Boring fixation element of conctructions
Sphere of technique
Technical solution concerns boring fixation element of constructions for dismantle screw connection with other bar material. This connection can be applied for fixation of billboards, traffic signs, light buildings or also for construction of solar systems.
Present state of technique
So far known boring fixation elements have the lower part determined for boring into soil solved oracticallv exclusively as r"."°t drills. It is known e.g. fixation element which is equiped on its lower end with twist drill fixed on a shaft, whereas the shaft on upper level of drill is expanding by means of conic section to upper tubular part. Twist drill has in its whole part the same area of webs and it is made on the shaft only in extension to 360°. This arrangement results in problematic regulation of boring element in stony soil where it is possible to tamping* of twist drill' with & stone. Owing io tampmg tπe element' stops boring to deep of Soil and'if the serviceman does not stop its activity twist drill can be'totaliy' 1 ' 1 < ' destructed'by acting pressures.
InF order to eurήiriate these problems a new rather different solid boring basis was made. This bas'« consists of the substance equiped at the lower end with a helix placed over the too. Area of he'ix web is spreadine from top towards the end and at the sarne time helix has extension bigεer than 3&IT. 1 his arangement is less risky trom the, point of view nt tamping (e.g. by . stone) and so following possible destruction. On the other hand neither at this arangement , sufficient space is formed for optimal passage of soil or stony subsoil at drilling. , ,
OtheHack of present boring elements i≤ their connection- with other elements of fixed ' construction. Tt is realized practically exclusively building-in of end of ohe^ eiernent fά ' tøther 0 and fixation with' bnetfansverse connecting element on bbringhube. ft is khoWri iπ practice that sucfr connection is not sufficient especially at bigger constructions (such as construction of solar, systems) and in exact weather conditions.
Sύbstatfce ohechπical 1 solution
Borine fixation element of constructions according to put forvard technical solution contribute, to significant extent to removal of above mentioned lacks, ot so tar Known boring
elements. This boring element is similarly known as fixation elements formed by boring tube at the lower end of which there is conus fastened by finished apex.
Substance of technical solution results in that two blades at least are fixed to conus whose areas at conus towards from too UD are gradualy expanding and further boring tube has at its upper end kept two connecting elements at least.
The blades can be two ones with the advantage that they are placed at conus against to each other under angles 15 to 75°. As for the form of blades it is advantageous if they have the form o f round curve whereas round parts of blades are oriented towards from axis of conus.
Connecting elements placed in the web of boring tube are oriented with advantage of their axes perpendicular to axis of boring tube and they are rne srews which can be adva • nJ tage w ! ith them.
Boring fixation element of constructions according to given technical solution is advantageous especially by optimal solution of its boring part. The use of separate blades instead of connected helix prevents from tamping and makes space for optimal passage of soil or stony subsoil at drilling. It also speeds conspicuously time of screw boring and makes sure better guidance of boring tube in demanding direction. Owing to the use of two connecting elements at least placed at upper end in the web of boring tube it is optimalized even connection of boring fixation element with other elements of construction and so it suits to 1 even particular applications and climate conditions.

Example of practicability
_Boring fixation element of constructions of solar systems ( pict. 1 and 2) is formed by boring tube 4_ at the lower end of which conus is fixed finished with an apex. Two blades J_ are fixed to conus 2 whose areas at conus 2_are expanding up in the direction from apex 3_. Boring tube 4_has at its upper end two (pict 4) or three (pict.5) connecting srews kept in the web which with their axes are oriented perpendicular to the axis of boring tube 4.
Blades J_have the form of area of round curve, where round parts of blades l_are oriented towards from axis of conus. Blade expand i at conus 2_ (start of a curve) is less outstanding at boring element for more permeable terrain (earth ) - see pict. 2 and more outstanding at boring element for bad permeable (stony) terrain - see pict. 3.
