Description A SPACE ADIABATIC BLOCK

Technical Field

[1] The present invention relates to a space-adiabatic block, and more particularly, a space-adiabatic block having an improved structure in which masonry construction is easily performed and gaps between blocks during construction are not formed. Background Art

[2] There are many methods of constructing a wall body for a building. Among them, in a masonry construction method, blocks are doubly stacked in a using cement mortar, an adiabatic material is inserted and built in the middle of the blocks and then both sides or one side of the wall body is plastering-treated.

[3] However, when the wall body is constructed using the above-described masonry construction, it is difficult by a usual worker (not a person skilled in masonry construction) to make a block- stacking work. Even when the person skilled in masonry construction stacks blocks, many gaps between blocks are actually formed, and even when an adiabatic material is installed in the middle of the wall body, insulation, soundproof and waterproof are not perfect. Thus, in spite of the strengthening of standards for using an adiabatic material by the government, there are problems that insulation of general buildings is not perfect and high costs for air-conditioning and heating are required in maintenance. Disclosure of Invention Technical Problem

[4] The present invention provides a space-adiabatic block of which construction is easy so that a user can perform masonry construction conveniently and in which insulation, soundproof and waterproof are perfectly achieved.

[5] The present invention also provides a space-adiabatic block in which subsequent processes such as plastering inside a wall body or exterior finishing needs not to be performed and costs for subsequent processes and a construction period can be remarkably reduced. Technical Solution

[6] According to an aspect of the present invention, there is provided a space-adiabatic block comprising: a first mortar groove 11, 21 or 31 which is formed to be long in a portion of upper ends of the space-adiabatic block; a second mortar groove 12, 22 or 32 which is formed to be long in at least one of vertical sides of the space-adiabatic

block; a mortar pin groove 13, 23 or 33 which is formed in each of the second mortar grooves 12, 22 and 32, starts from the corner end of each of the second mortar grooves

12, 22 or 32 and extends to the lower end of each of the second mortar grooves 12, 22 and 32 and into which a spray rod Gl of a urethane gun G is injected; and a pin body groove 14, 24 or 34 which is formed in a portion in which each of the first mortar grooves 11, 21 and 31 and each of the mortar pin grooves 13, 23 and 33 intersect and in which a body P2 of a connection pin P engaged in each of the mortar pin grooves

13, 23 and 33 is installed.

[7] Each pair of inclined surfaces 1 Ia and 12a, 21a and 22a, 31a and 32a may be formed in both insides of each pair of the first and second mortar grooves 11 and 12, 21 and 22, 31 and 32 respectively, so that cross-sections of each pair of the first and second mortar grooves 11 and 12, 21 and 22, 31 and 32 can be inverted-trape»id-shaped.

[8] A space groove may be formed in a front side of the space-adiabatic block to be deeply dug to direct toward the same direction as that of each of the first mortar grooves 21 and 31. At least one reinforcement protrusion 25a or 35a may be formed in the space groove 25 or 35 so as to improve overall durability.

Best Mode for Carrying Out the Invention

[21] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

[22] The space-adiabatic block according to the present invention has three embodiments, and each of the embodiments are defined as a first space-adiabatic block 10, a second space-adiabatic block 20, and a third space-adiabatic block 30.

[23] FIG. 1 is a perspective view of a space-adiabatic block according to an embodiment of the present invention, and FIG. 2 is a side view of the space-adiabatic block of FIG. 1 from a direction of arrow A.

[24] As illustrated in FIG. 1, the space-adiabatic block according to an embodiment of the present invention (hereinafter referred to as a first space-adiabatic block 10) comprises a first mortar groove 11 formed to be long in a portion of upper ends of the space- adiabatic block, a second mortar groove 12 formed to be long in at least one of vertical sides of the space-adiabatic block, a mortar pin groove 13 starting from the corner end of the second mortar groove 12 and extending to the lower end of the second mortar groove 12, and a pin body groove 14 which is formed in a portion in which the first mortar groove 11 and the mortar pin groove 13 intersect and in which a body P2 (see FIG. 10) of a connection pin P engaged in the mortar pin groove 13 is installed.

[25] Watery cement mortar is filled or polyurethane is sprayed and fired and filled in the first and second mortar grooves 11 and 12.

[26] The cross-sections of the first mortar groove 11 and the second mortar groove 12 may be in verted- trapezoid- shaped. To this end, inclined surfaces 1 Ia and 12a are formed in both insides of the first and second mortar grooves 11 and 12, respectively, as illustrated in FIG. 2. The inclined surfaces 11a and 12a are formed so that, when the first space-adiabatic block 10 made of cement and mortar is formed using molding, both inner corners of the first and second mortar grooves 11 and 12 can be prevented from being grated.

[27] Any one of both ends Pl and P3 of the " τ= "-shaped connection pin P is inserted in the mortar pin groove 13 and simultaneously, watery cement mortar or polyurethane is filled in the mortar pin groove 13. The mortar pin groove 13 extends to the lower end of the second mortar groove 12 and a side portion thereof is deeper than the second mortar groove 12. In this case, the extended length of the mortar pin groove 13 varies according to the size of the first space-adiabatic block 10. For example, the size of the first space-adiabatic block 10 is small and when the length of the second mortar pin groove 12 is about 100 mm, the extended length of the mortar pin groove 13 is about 50 mm and the size of the first space-adiabatic block 10 is large and when the length of the second mortar pin groove 12 is about 200 mm, the extended length of the mortar pin groove 13 is about 150-170 mm. In other words, the extended length of the mortar pin groove 13 is extended to a position in which, as the size of the first space-adiabatic block 10 increases and the length of the second mortar groove 12 increases, the mortar pin groove 13 approaches the lower end of the second mortar groove 12.

[28] A space-adiabatic block according to another embodiment of the present invention will now be described.

[29] FIG. 3 is a perspective view of a space-adiabatic block according to another embodiment of the present invention, FIG. 4 is a side view of the space-adiabatic block of FIG. 3 from a direction of arrow B, FIG. 5 illustrates space grooves formed in the front and rear sides of the space-adiabatic block of FIG. 3, and FIG. 6 illustrates reinforcement protrusions formed in space grooves when the space-adiabatic block of FIG. 3 is fabricated in a larger size.

[30] As illustrated in FIG. 3, the space-adiabatic block according to another embodiment of the present invention (hereinafter referred to as a second space-adiabatic block 20) comprises a first mortar groove 21 formed to be long in a portion of upper ends of the space-adiabatic block, a second mortar groove 22 formed to be long in at least one of vertical sides of the space-adiabatic block, a mortar pin groove 23 starting from the corner end of the second mortar groove 22 and extending to the lower end of the second mortar groove 22, and a pin body groove 24 which is formed in a portion in which the first mortar groove 21 and the mortar pin groove 23 intersect and in which a body P2 (see FIG. 10) of a connection pin P engaged in the mortar pin groove 23 is installed.

[31] In this case, as illustrated in FIG. 4, a space groove 25 is formed in a front side of the second space-adiabatic block 20 to be deeply dug to direct toward the same direction as that of the first mortar groove 21. However, a space groove 25' may also be formed

in both front and rear sides of the second space-adiabatic block 20, as illustrated in FIG. 5.

[32] Watery cement mortar is filled or polyurethane is sprayed and fired and filled in the first and second mortar grooves 21 and 22.

[33] The cross-sections of the first mortar groove 21 and the second mortar groove 22 may be in verted- trapezoid- shaped. To this end, inclined surfaces 21a and 22a are formed in both insides of the first and second mortar grooves 21 and 22, respectively, as illustrated in FIG. 4. The inclined surfaces 21a and 22a are formed so that, when the second space-adiabatic block 20 made of cement and mortar is formed using molding, both inner corners of the first and second mortar grooves 21 and 22 can be prevented from being grated.

[34] Any one of both ends Pl and P3 of the " τ= "-shaped connection pin P is inserted in the mortar pin groove 23 and simultaneously, watery cement mortar or polyurethane is filled in the mortar pin groove 23. The mortar pin groove 23 extends to the lower end of the second mortar groove 22 and a side portion thereof is deeper than the second mortar groove 22. In this case, the extended length of the mortar pin groove 23 varies according to the size of the second space-adiabatic block 20. For example, the size of the second space-adiabatic block 20 is small and when the length of the second mortar pin groove 22 is about 100 mm, the extended length of the mortar pin groove 23 is about 50 mm and the size of the second space-adiabatic block 20 is large and when the length of the second mortar pin groove 22 is about 200 mm, the extended length of the mortar pin groove 23 is about 150-170 mm. In other words, the extended length of the mortar pin groove 23 is extended to a position in which, as the size of the second space-adiabatic block 20 increases and the length of the second mortar groove 22 increases, the mortar pin groove 23 approaches the lower end of the second mortar groove 22.

[35] The space grooves 25 and 25' are implemented while being deeply dug in front and/ or rear side of the second space-adiabatic block 20 to direct toward the same direction as that of the first mortar groove 21. Due to the space grooves 25 and 25, when the wall body is constructed using the second space-adiabatic block 20, space layers are formed in the middle of the wall body so that an insulation and soundproof efficiency is improved and a thermal conductive loss is minimized. The front side portion of the second space-adiabatic block 20 in which the space groove 25 is formed is close to an adiabatic material A.

[36] On the other hands, the second space-adiabatic block 20 may be fabricated in a larger

size. In this case, the inner space of the space groove 25 of the second space-adiabatic block 20 increases and the strength at which the second space-adiabatic block 20 withstands the external shock needs to be increased. To this end, as illustrated in FIG. 6, at least one reinforcement protrusion 25a is formed in the space groove 25 to be long along the space groove 25.

[37] Next, a space-adiabatic block according to another embodiment of the present invention will now be described.

[38] FIG. 7 is a perspective view of a space-adiabatic block according to another embodiment of the present invention, FIG. 8 is a side view of the space-adiabatic block of FIG. 7 from a direction of arrow C, and FIG. 9 illustrates reinforcement protrusions formed in space grooves when the space-adiabatic block of FIG. 7 is fabricated in a larger size.

[39] As illustrated in FIG. 7, the space-adiabatic block according to another embodiment of the present invention (hereinafter referred to as a third space-adiabatic block 30) comprises a first mortar groove 31 formed to be long in a portion of upper ends of the space-adiabatic block, a second mortar groove 32 formed to be long in at least one of vertical sides of the space-adiabatic block, a mortar pin groove 33 starting from the corner end of the second mortar groove 32 and extending to the lower end of the second mortar groove 32, a pin body groove 34 which is formed in a portion in which the first mortar groove 31 and the mortar pin groove 33 intersect and in which a body P2 (see FIG. 10) of a connection pin P engaged in the mortar pin groove33 is installed, and a space groove 35 implemented while being deeply dug in front and/or rear side of the third space-adiabatic block 30 to direct toward the same direction as that of the first mortar groove 31. In this case, a corner groove 36 is formed in the rear side of the third space-adiabatic block 30 along its corners so that a stripe line L can be formed in horizontal and vertical directions when the wall body is stacked.

[40] Watery cement mortar is filled or polyurethane is sprayed and fired and filled in the first and second mortar grooves 31 and 32.

[41] The cross-sections of the first mortar groove 31 and the second mortar groove 32 may be in verted- trapezoid- shaped. To this end, inclined surfaces 31a and 32a are formed in both insides of the first and second mortar grooves 31 and 32, respectively, as illustrated in FIG. 8. The inclined surfaces 31a and 32a are formed so that, when the third space-adiabatic block 30 made of cement and mortar is formed using molding, both inner corners of the first and second mortar grooves 31 and 32 can be prevented from being grated.

[42] Any one of both ends Pl and P3 of the " τ= "-shaped connection pin P is inserted in the mortar pin groove 33 and simultaneously, watery cement mortar or polyurethane is filled in the mortar pin groove 33. The mortar pin groove 33 extends to the lower end of the second mortar groove 32 and a side portion thereof is deeper than the second mortar groove 32. In this case, the extended length of the mortar pin groove 33 varies according to the size of the third space-adiabatic block 30. For example, the size of the third space-adiabatic block 30 is small and when the length of the second mortar pin groove 32 is about 100 mm, the extended length of the mortar pin groove 33 is about 50 mm and the size of the third space-adiabatic block 30 is large and when the length of the second mortar pin groove 32 is about 200 mm, the extended length of the mortar pin groove 33 is about 150-170 mm. In other words, the extended length of the mortar pin groove 33 is extended to a position in which, as the size of the second space- adiabatic block 30 increases and the length of the second mortar groove 22 increases, the mortar pin groove 33 approaches the lower end of the second mortar groove 32.

[43] Due to the space groove 35, when the wall body is constructed using the third space- adiabatic block 30, space layers are formed in the middle of the wall body so that an insulation and soundproof efficiency can be improved and a thermal conductive loss can be minimized. The front side portion of the third space-adiabatic block 30 in which the space groove 35 is formed is close to an adiabatic material A.

[44] A decoration stripe line L directing toward horixmtal and vertical directions is formed in the corner groove 36 when the wall body is constructed using a plurality of third space-adiabatic blocks 30.

[45] On the other hands, the third space-adiabatic block 30 may be fabricated in a larger size. In this case, the inner space of the space groove 35 of the third space-adiabatic block 30 increases and the strength at which the third space-adiabatic block 30 withstands the external shock needs to be increased. To this end, as illustrated in FIG. 9, at least one reinforcement protrusion 35a is formed in the space groove 35 to be long along the space groove 35.

[46] A method of constructing the wall body using the first, second and third space- adiabatic blocks 10, 20 and 30 will now be described.

[47] FIG. 10 illustrates a wall body constructed using the space-adiabatic block of FIGS.

1 through 9, and FIG. 11 illustrates the operation in which polyurethane is sprayed and fired from a spray rod of a polyurethane gun inserted in mortar pin grooves and is filled in a second mortar groove and a mortar pin groove when the wall body of FIG. 10 is constructed.

[48] When the wall body is constructed using the first, second and third space-adiabatic blocks according to the present invention, a used material may be watery cement mortar or polyurethane (U). In this case, watery cement mortar is scooped using a tool such as kote and polyurethane (U) is sprayed using a spray rod Gl of a well-known urethane gun G.

[49] In order to construct the wall body using the first, second and third space-adiabatic blocks, firstly, a piece of the first space-adiabatic block 10 is put on a corner outside the wall body to be stacked, and subsequently, the third space-adiabatic block 30 is put outside the wall body in a line so that the space groove 25 is directed toward the direction in which the adiabatic material is disposed, and then, watery cement mortar is filled or polyurethane (U) is sprayed in the second mortar groove 32 and the mortar pin groove 33, thereby one-step stacking the third space-adiabatic block 30.

[50] After that, watery cement mortar is filled or polyurethane (U) is sprayed and fired in the first mortar groove 31 that is formed to be long on upper ends of the third space- adiabatic block 30 that forms one step.

[51] Subsequently, the third space-adiabatic block 30 is continuously stacked using the previously-described one-step method so that blocks outside the wall body are stacked to the depth of a previously -cut adiabatic material.

[52] Of course, the depth of the previously-presented adiabatic material A is cut to the depth at which the " τ= "-shaped connection pin P is inserted.

[53] When blocks outside the wall body are stacked to the depth of the adiabatic material

A, the adiabatic material A is disposed in a line and the second space-adiabatic block 20 is put inside the wall body. In this case, the space groove 25 of the second space- adiabatic block 20 is directed toward the adiabatic material A and subsequent processes are performed using the same method as construction outside the wall body.

[54] When insides of the wall body are stacked to the depth of the previously -cut adiabatic material, both ends Pl and P3 of the " τ= "-shaped connection pin P are inserted in the mortar pin grooves 23 and 33 of the space-adiabatic walls 20 and 30 stacked inside and outside the wall body so that the adiabatic material A and the second and third space-adiabatic blocks 20 and 30 stacked on both sides of the adiabatic material A are formed as one body.

[55] Here, a portion of the wall body constructed using the second space-adiabatic block

20 forms an interior of a building and a portion of the wall body constructed using the third space-adiabatic block 30 forms an exterior of the building.

[56] In addition, watery cement mortar or polyurethane (U) used as a filling material is

filled in a mortar groove or a mortar pin groove and then is solidified after a predetermined amount of time so that the second space-adiabatic block 20 different from the second space-adiabatic block 20' and the third space-adiabatic block 30 different from the third space-adiabatic block 30' are formed as one body.

[57] Here, when space-adiabatic blocks are disposed in a line, watery cement mortar does not need to be scooped to sides of each block or polyurethane (U) does not need to be sprayed thereon like in the conventional construction method. This is because the mortar pin grooves 13, 23 and 33 are formed in a vertical direction. That is, watery cement mortar flows into gaps of the mortar pin grooves 13, 23 and 33 in which a groove gap between blocks is secured, but does not flow sideways so that a work for filling watery cement mortar in the first mortar grooves 11, 21 and 31 formed to be long on upper ends of the space-adiabatic block, the second mortar grooves 12, 22 and 32 in a vertical direction and the mortar pin grooves 13, 23 and 33 can be simultaneously finished at one time.

[58] Snce, even when construction is performed using polyurethane (U), the spray rod

Gl of the urethane gun G is easily injected into the mortar pin grooves 13, 23 and 33, the space-adiabatic blocks are disposed in a line without the need of spraying polyurethane (U) onto each of sides of the space-adiabatic block and then, as a post- work, polyurethane (U) is sprayed onto sides of each of the mortar pin grooves 13, 23 and 33.

[59] In addition, polyurethane (U) sprayed by the spray rod Gl of the urethane gun G injected into the mortar pin grooves 23 and 33 is fired, expanded and ascended on the lower ends of the second mortar groove 12, 22 and 32, is filled in the mortar pin grooves 13, 23 and 33, is expanded and solidified so that the second space-adiabatic block 20 different from the second space-adiabatic block 20' and the third space- adiabatic block 30 different from the third space-adiabatic block 30' are formed as one body.

[60] Snce, when space-adiabatic blocks are disposed in a line, watery cement mortar does not need to be scooped to sides of each block or like in the conventional construction method, the above-described operation is simply and quickly performed so that the construction speed of the wall body can be remarkably increased.

[61] When the wall body is stacked using the above-described method, due to the corner groove 36 formed in the third space-adiabatic block 30, a decoration stripe line L directing toward horixmtal and vertical directions is naturally formed at a surface formed with the third space-adiabatic block 30 outside the wall body.

[62] While the present invention has been particularly shown and described with

reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims. Industrial Applicability

[63] As described above, the space-adiabatic block according to the present invention comprises a first mortar groove formed to be long in a portion of upper ends of the space-adiabatic block, a second mortar groove formed to be long in at least one of vertical sides of the space-adiabatic block, a mortar pin groove starting from the corner end of the second mortar groove and extending to the lower end of the second mortar groove, and a pin body groove which is formed in a portion in which the first mortar groove and the mortar pin groove intersect and in which a body of a connection pin engaged in the mortar pin groove is installed. Thus, when space-adiabatic blocks are stacked, construction is easy so that a usual worker (not a person skilled in masonry construction) can perform masonry construction conveniently, a space layer is formed in the middle of the wall body so that a thermal conductive loss is minimized and insulation, soundproof and waterproof are perfectly achieved and the thickness of the wall body to be constructed can be reduced.

[64] Furthermore, subsequent processes such as plastering inside a wall body or exterior finishing after the wall body is constructed can be omitted and costs for subsequent processes and a construction period can be remarkably reduced.
