Description

H shaped steel web adjustable drilling casement

Technical field

The utility model belongs to mould, especially relates to a kind of boring mould.

Background technology

Existing steel-structure factory building and framework, adopt the H section steel manufacture more and more universal, in the fabrication and installation of H shaped steel steel-structure factory building and framework, post and post, post and beam, high-strength bolt is adopted in connection between the Liang Yuliang more and more, traditional being welded to connect just gradually is eliminated, and adopt high-strength bolt to connect, also more and more thereupon at the web of H shaped steel or the boring amount on the flange plate, state-of-the-art method for drilling is to adopt three-dimensional drilling machine on H shaped steel web or flange plate, but it is higher to purchase this complete equipment expense, and apparatus body is bigger, also higher to site area and environmental requirement on every side, at present, generally the bore mode of Cai Yonging is to adopt the hollow magnetic force of import to bore or common magnetic force brill outfit locating template, 1, adopt the hollow magnetic force of import to bore, need before the boring manually to mark the position line in each hole on H shaped steel web or wing plate, also will check and approve pitch-row each other repeatedly after make in each hole, it is bigger influenced by human factor, quality has deviation unavoidably, and holding time is more; 2, adopt common magnetic force to bore and be equipped with locating template, but locating template fixedly is more thorny thing, conventional method: the locating template point is welded on the H shaped steel web or flange plate that needs boring, drilling finishes the back worn crator of sanding machine, because this bore mode has slight damage to mother metal, for the position that component quality is had relatively high expectations, this mode is not allowed to; As on H shaped steel web or flange plate, marking the boring position line by locating template earlier, also can only mark the edge line in hole, and the drill center position is determined not, be difficult to guarantee that its boring does not depart from, so also be difficult to guarantee the drilling quality requirement.

Summary of the invention

The purpose of this utility model provides a kind of H shaped steel web adjustable drilling casement, improves the efficient of holing and guarantee drilling quality on H shaped steel web, the reduction of erection time, reduces production costs.

The purpose of this utility model is achieved like this: a kind of H shaped steel web adjustable drilling casement, it is characterized in that: this H shaped steel web mainly is made up of locating template, fixed mount, handle, adjusting screw bolt and nut with the adjustable drilling casement, locating template is made by steel plate, its thickness is 8mm-12mm, its length is less than the width of H shaped steel web to be holed, on locating template, bore datum hole, decide according to drawing design the size of this datum hole, position, depicts horizontal and vertical center line as reference center's line on the upper surface of locating template; Fixed mount is inverted right angle U-shaped, form by the steel plate cutting, thickness is 20mm-25mm, the width of the straight trough of this fixed mount is greater than the thickness of H shaped steel flange plate to be holed, the degree of depth is greater than the height of this H shaped steel flange plate to be holed, be welded on the lower end of a side of this fixed mount nut and screw is about to setting, and the lower end Duan Ze of another side of fixed mount is oblique overhanging; With locating template have one of reference center's line face up and its length is about to horizontal positioned, symmetry and compartment of terrain, the front and back fixed mount that vertically is welded respectively on the left end limit of locating template upper surface and right-hand member limit, an oblique overhanging end that is about to two fixed mounts that are provided with before and after being is fixed with the corresponding welding in same end limit of the upper surface of locating template, and the handle that between upper end, is welded with the front and back fixed mount on limit, for carrying or mechanical this H of handling shaped steel web adjustable drilling casement with hand, the difference spinning is regulated bolt in the nut on each fixed mount.

During use, H shaped steel is lain on ground or the support, web to be holed is faced up, this web boring mould is placed on the position that H shaped steel need hole, straight trough correspondence on each fixed mount is on the flange plate of H shaped steel two sides, reference center's line of adjusting on the locating template makes it consistent with the centre of location line on the H shaped steel web, tighten the adjusting bolt on each fixed mount, itself and H shaped steel two flank listrium surfaces are held out against, place the magnetic force brill then and begin boring by the datum hole on the locating template, guarantee drilling quality, after institute's hole jewel is intact, regulates bolt, take off this boring mould for loosening four, iron filings are removed totally, so just can be put into the bore operation in other places.

The H shaped steel web adjustable drilling casement that the utility model proposes, rational in infrastructure, easy to use and reliable, drilling efficiency height on H shaped steel web, drilling quality is good, has shortened the duration, has reduced production cost.

Now in conjunction with the accompanying drawings and embodiments the H shaped steel web that the utility model proposed is further described with the adjustable drilling casement.
