Description STEEL SECTION CONNECTION DEVICE
Technical Field
[1] The invention relates to steel section connection device. More particularly, the invention relates to a steel section connection device with which steel sections can be connected by means of simple snap quick connection or fitting. Background Art
[2] Since such steel sections, however, are fabricated to a given length during the manufacturing process, they are cut to the required length and then connected again as necessary. An example of such connection is bolt connection or welding. That is to say, it is to connect two sections by means of bolts and nuts after abutting them then to form bolt holes. For bolt holes, rivets can be used instead of bolts.
[3] For welding joint, two steel sections are abutted to weld the abutted portions into an integral whole. If required, bolts, rivets and welding joints can be used together.
[4]
Disclosure of Invention Technical Problem
[5] However, such this prior art method of connecting steel sections has a number of disadvantages. That is, bolt holes must be made for each steel section connection one by one. After that bolts and nuts must be used to couple them one by another, so the process requires much time and, accordingly, is not cost effective. In particular, for a place where there is much load or vibration, an additional problem is that the connecting bolts and nuts are self-loosening.
[6] Since the welding joint is a permanent connection, it is impossible to disconnect welded sections without marks and defects (for example, alien substances are likely to be mixed and cavities, cracks, and other deformations are likely to occur). Therefore, for a place where there is much load or vibration, non-destructive inspection must be carried out for each connection after welding-this is a labor-consuming and inefficient process. In particular, it is hard to attain the precise constructiveness and safety as the welded portion can be deformed or its mechanical properties can change because of welding heat.
[7]

Mode for the Invention
[70] Hereinafter, the invention will be described in more detail with reference to the accompanying drawings showing preferred embodiments of the invention. [71] Embodiment 1
[72] Fig.1 is an exploded perspective view of a steel section connection device according to one embodiment of the invention. Fig.2 is a perspective view showing the assembled steel section connection device in Fig.1, and Fig.3 is a top view of the first steel section fixing frame 300 shown in Fig.1. [73] As shown in Figs.1 to 3, the steel section connection device according to one embodiment of the invention consists of a first steel section ('angle') 100, a wedge member 200 and a first steel section fixing frame 300. [74] The first steel section 100 is L-shaped in its longitudinal cross section, and this con-
figuration is typically well known from the prior art.
[75] The wedge member 200 is shaped approximately a trigonal prism, but has an inclined surface 220 on one side. Such a wedge member 200 is made of metal. The height of the wedge member 200 is equal or smaller than that of the vertical wall 310.
[76] The first steel section fixing frame 300 consists of an approximately triangular bottom plate 330, a vertical wall and an inclined wall 320, both walls projecting vertically from the bottom plate 330.
[77] The vertical wall 310 is formed to be perpendicular so that one surface of the first steel section 100 can be tightly coupled, and has a given height from the bottom plate 330. The inclined wall 320 projects from the bottom plate 330 to be inclined at a given angle toward the vertical wall 310. Such an inclined wall 320 has an internal wall and an outer wall inclined by the same angle, and has the same slope as that of the inclined surface 220 of the wedge member 200, particularly.
[78] One side of the inclined wall 320 is spaced from one side of the vertical wall 310 by the same or greater space than the thickness of the first steel section 100. In the space, the first steel section 100 is fitted. Therefore, a gap between one side of the inclined wall 320 and a side of the vertical wall 310 will suffice if it is the same as the thickness of the first steel section 100 or allows the first steel section to be fitted.
[79] The approximately triangular space formed by the top part of the inclined wall 320 and the top part of the vertical wall 310 is dimensioned large enough so that the wedge member 200 could pass through the space. This is for assembling the wedge member before the first steel section 100 is fitted.
[80] After separately manufacturing each wall 310 and 320 and the bottom plate 300, the first steel section fixing frame 300 described above can be welded thereto. It can be integrated therewith by casting or forging or a combination of forging, welding and casting.
[81] Fig.4 is a perspective view of the first example of a wedge member 200 shown in
Fig.1. As shown in Fig.4, the top surface of the wedge member 200 is an isosceles right-angled triangle and the wedge member consists of two vertical surfaces 210, one inclined surface 220 and the bottom surface (not lettered). The wedge member 200 is shaped to make a larger contact area. Two vertical surfaces 210 are made for tight coupling to the bent portion of the first steel section 100. The inclined surface 220 has the same slope as that of the inclined wall 320 of the first steel section fixing frame 300. This is made so that the inclined surface 220 can be tightly coupled to the internal surface of the inclined wall 320 of the first steel section fixing frame 300. The middle part of the wedge member 200 can be provided with an empty space.
[82] Fig.5 is a perspective view of the second example of a wedge member 200 shown in
Fig.1. As shown in Fig.5, teeth 235 are formed in horizontal direction on the boundary
surface (inclined surface, vertical surface) of the wedge member 200 to form a tooth- profiled surface 230. Such a tooth-profiled surface 230 increases friction force between the first steel section 100 and the first steel section fixing frame 300 which adjoin one another, so that the first steel section 100 can be coupled with a greater pull force. The teeth 235 can be large or small. The middle part of the wedge member 200 can be provided with an empty space.
[83] Fig.6 is a perspective view of the third example of the wedge member 200 shown in
Fig.1, As shown in Fig.6, the area adjoining to the inclined wall 320 can be further reinforced.
[84] Fig.7 is a cross section showing the first example of the position fixing means to the steel section connection device shown in Fig.2. As shown in Fig.7, the position fixing means is a coupling means used to achieve uniform coupling of the wedge member 200 to the first steel section fixing frame 300 or to fix them. There is a recess 240 in the wedge member 200 to make an empty space; the recess being open toward the bottom plate 330.
[85] One end of the first spring 245 is fitted in the recess 240 to push up the wedge member 200, and the other end thereof is supported by the bottom plate 330. Owing to the elasticity of the first spring 245, the wedge member 200 attempts to intervene between the first steel section 100 and the inclined wall 320 all the time, thereby causing high friction force ensuring strong connection. In order to disconnect the first steel section 100, it is required to hit the wedge member 200 with a hammer to lower the wedge member 200 and then to take out the first steel section 100.
[86] Fig.8 shows a cross section showing the second example of the position fixing means to the steel section connection device shown in Fig.2. As shown in Fig.8, there is a recess 240 in the wedge member 200 to make an empty space, which is open toward the bottom plate 330. The bolt hole 247 is provided on top of the recess 240.
[87] The fixing bolt 250 is fitted in the bolt hole 247 to ensure thread engagement. One end of the fixing pin 260 is fixed to the inclined wall 320 of the wedge member 200 by means of welding, and the middle part thereof is bent so that the fixing bolt 250 could pass through twice. The free end of the fixing pin 260 is exposed so that one can hold it with his hand. There is a plate spring in the middle part of the fixing pin 260 to ensure elasticity so that the fixing pin 260 is always at the given angle.
[88] The second spring 270 is applied around the fixing bolt 250, and lets the fixing pin some space therein 260. Accordingly, tightening the fixing bolt 250 results in raising the wedge member 200, and loosening the fixing bolt 250 results in lowering the wedge member 200.
[89] Either or both of the plate spring of the fixing pine 260 and the second spring 270 can be not used.
[90] Fig.9 shows a cross section showing the third example of the position fixing means to the steel section connection device shown in Fig.2.
[91] As shown in Fig.9, the height of the vertical wall 310 can be half of the height shown in Fig.8. For the position fixing means, the size and direction of the fixing pin 260 can be modified.
[92]

As shown in Fig.10, two first steel section fixing frames 300 are coupled one to another to form a second steel section fixing frame 400. In this case, for the coupling of two first steel section fixing frames 300, they are arranged to be coupled while the first steel section 100 is at 90 . That is, the bottom plate 330 of one first steel section fixing frame 300 is integrated to the vertical wall 310 of the other steel section fixing frame 300. In this case, each of the first steel sections 100 of the second steel section fixing frame 400 can be individually connected or disconnected. Of course, the aforementioned position fixing means can be applied thereto. The same description of the first steel section fixing frame 300 in the first embodiment holds true for the configuration and operation of the second steel section fixing frame 400, not discussed in detail herein.

As shown in Fig.11 , in order to connect a couple of the first steel section 100 in a straight line, a third steel section fixing frame 420 is used. That is, the third steel section fixing frame 420 is formed by coupling a pair of first steel section fixing frames 300. That is, the bottom plate 330 of one of the first steel section fixing frames 300 is fixed to the bottom plate 330 of the other first steel section fixing frame 300. In this case, each of the first steel sections 100 of the third steel section fixing frame 420 can be individually connected or disconnected.

frame 440 is used. That is, the fourth steel section fixing frame 440 is formed by connecting three first steel section fixing frames 300 together. That is, to the vertical wall 310 of one of the first steel section fixing frames 300, the bottom plate 330 of the other two of the first steel section fixing frames 300 is fixed, respectively. In this case, the first steel section 100 of the fourth steel section fixing frame 440 can be individually connected or disconnected.

As shown in Fig.13, in order to connect two first steel sections 100 in parallel, a fifth steel section fixing frame 460 is used. That is, the fifth steel section fixing frame 460 is formed by coupling two first steel section fixing frames 300 together. That is, the vertical wall 310 of one of the first steel section fixing frames 300 is fixed to the vertical wall 310 of the other first steel section fixing frames 300. In this case, the first steel section 100 of the fifth steel section fixing frame 460 can be individually connected or disconnected.
