Abstract
The utility model relates to a tower crane foundation construction tool, in particular to a control form for positions of foundation bolts of a fixed tower crane, achieves accurate positioning of foundation bolts and guarantees non-displacement of foundation bolts in concrete casting. The control form for positions of foundation bolts of the fixed tower cranes structurally comprises a rectangular frame, bolt positioning boards are fixed at positions of adjacent two corners of the frame, four foundation bolt holes are arranged on each bolt positioning board, connecting bolt holes are arranged at butt joint edges of the frame, and connecting bolts are disposed in the connecting bolt holes. The control form is simple in structure and reasonable in design, can accurately position positions of the 16 bolts of the tower crane and guarantees smooth construction.
Description
Technical field
The utility model relates to a kind of tower crane construction tool, is specially fundamentally foot bolt Position Control mould of a kind of fixed type tower crane.
Background technology
Although tower crane is not engineering entity ingredient, but having a strong impact on construction safety, should carry out quality control according to the equipment Foundations quality specifications during construction, part constructor thinks little of the tower crane quality control on construction, construction quality problem often occurs, or economic loss or stay potential safety hazard.Such as; in requiring, tower crane description basic technology generally all emphasizes; pre-embedded anchoring bolts must not be welded; but the site operation personnel are easy construction; at will with stone bolt and the welding of tower crane reinforcing bar; seriously reduced the mechanical property of stone bolt; stayed larger potential safety hazard; but foot bolt how regularly actually? the stone bolt relative position requires accurate especially again; and when the cast vibrated concrete, stone bolt is subjected to displacement, in case be subjected to displacement, can't lay the tower crane pedestal; tower crane then frame does not get up immediately, and can't adjust.The method of often taking is to take the method for bar planting again to implant stone bolt, and the expense of so both having taken a lot of work material has been incured loss through delay the duration again.
Summary of the invention
The utility model is accurately located for solving stone bolt, guarantees simultaneously the unshift problem of stone bolt when concreting, and fundamentally foot bolt Position Control mould of a kind of fixed type tower crane is provided.
The technical solution of the utility model is, a kind of fixed type tower crane is foot bolt Position Control mould fundamentally, structure comprises the framework of rectangle, position at two adjacent angles of framework is fixed with the Bolt to position plate, the Bolt to position plate is provided with four anchor (bolt) holes, butt joint edge at framework is provided with the connecting bolt hole, and connecting bolt is installed in the connecting screw hole.
Mould described in the utility model is Split type structure, need two moulds during use, two butt joint edges are bolted, and four Bolt to position plates of such two moulds lay respectively at the position at foursquare four angles, form tower crane bolt position fixed mould.
After the colligation of tower crane reinforced mesh is complete, said apparatus is placed, 16 hole correspondences are enclosed within on 16 stone bolt that place in advance on it, use pad, nut that stone bolt is fixed on this mould firmly.Even die location has been subjected to displacement when concrete perfusion, the relative position of 16 eyelets (being stone bolt) on the mould can not change yet, and when installing and fixing the tower crane pedestal, the situation of just having avoided stone bolt to wear to advance the foundation bolt eyelet occurs.
The utility model is simple in structure, and is reasonable in design, 16 bolt positions of tower crane accurately can be located, and guarantees that construction is smooth and easy.
Description of drawings
Fig. 1 is structural representation of the present utility model
Among the figure: 1-framework, 2-Bolt to position plate, 3-anchor (bolt) hole, 4-connecting bolt, 5-butt joint edge.
The specific embodiment
As schematically shown in Figure 2, a kind of fixed type tower crane is foot bolt Position Control mould fundamentally, structure comprises the framework 1 of rectangle, position at two adjacent angles of framework 1 is fixed with Bolt to position plate 2, Bolt to position plate 2 is provided with four anchor (bolt) holes 3, butt joint edge 5 at framework is provided with the connecting bolt hole, and connecting bolt 4 is installed in the connecting screw hole.
Bolt to position plate 2 is the steel plate of 300mm * 300mm * 10mm, upward respectively bores the anchor (bolt) hole of 4 ￠ 30 on it by stone bolt relative position among the tower crane figure, and the center distance in hole is the center distance of bolt.(specification 50mm * 50mm * 5mm) welds 2 bearings and forms a rectangular frame four 5# angle steel of framework 1 usefulness of rectangle, and make a call to two connecting bolt holes at that the vertical leg that does not have a backed angle steel, connect when being used for using and fix two fan moulds.Two other mould also can be welded the same rectangle of formation.Separately make the same mould of two fans, conveniently carry and deposit.Look for a smooth location during welding, guarantee the relative position absolutely accurate of bearing and bearing and upper eyelet thereof.
After the colligation of tower crane reinforced mesh is complete, this two fans mould is connected with bolt, 16 hole correspondences are enclosed within on 16 stone bolt that place in advance on it, use pad, nut that stone bolt is fixed on this mould firmly.Even die location has been subjected to displacement when concrete perfusion, the relative position of 16 eyelets (being stone bolt) on the mould can not change yet, and when installing and fixing the tower crane pedestal, the situation of just having avoided stone bolt to wear to advance the foundation bolt eyelet occurs.
