Background technology
In the buildings such as hydroelectric project power plant building, dam, water inlet, usually need the pre-embedded steel slab when concrete structure pouring, as the pad of the steel work such as later stage cable testing bridge, railing, gate slot.Traditional way is after structure reinforcing bars colligation, is connected by the pre-embedded steel slab with lacing wire, then formwork erection, then concreting with structure reinforcing bars spot welding.Because formwork erection carries out after pre-embedded steel slab location, usually because inaccurate, the fixing reason loosely in pre-embedded steel slab location, pre-embedded steel slab surface is difficult to be adjacent to template, after causing the complete form removal of concreting, pre-embedded steel slab can not expose the problem of concrete surface, artificial chisel must be adopted to remove concrete, to make pre-embedded steel slab exposure in concrete surface, waste time and energy.And after pre-embedded steel slab surface concrete cuts, there is the discrepancy in elevation in concrete surface and pre-embedded steel slab surface, causes difficulty to weld job between steel work and pre-embedded steel slab.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of pre-embedded steel slab being applicable to wooden model, this pre-embedded steel slab being applicable to wooden model is fastened by bolts power makes pre-embedded steel slab firmly locate accurately on wooden form the mode that pre-embedded steel slab surface and wooden model surface are close to, and ensure that pre-embedded steel slab can expose structural concrete surface, eliminate the operation of artificial chisel except pre-embedded steel slab surface concrete, and reduce the difficulty of steel work and pre-embedded steel slab weld job.
The utility model is achieved by the following technical programs.
A kind of pre-embedded steel slab being applicable to wooden model that the utility model provides, comprises wooden form, pre-embedded steel slab, lacing wire, bolt, the lumps of wood, nut; Described wooden form and pre-embedded steel slab surface are close to, and wooden form and pre-embedded steel slab are fixed through wooden form and pre-embedded steel slab attaching nut by bolt; Described lacing wire welding edges pre-embedded steel slab relative to wooden form another on the surface; The quantity of described lacing wire is more than two; Described wooden form is also fixed with the lumps of wood on the surface, between wooden form and nut relative to another of pre-embedded steel slab.
Also comprise billet, billet is fixed between nut and the lumps of wood; On the contact surface of billet and the lumps of wood, billet covers the lumps of wood completely.
Described lumps of wood length is more than or equal to the width of wooden form.
The diameter of described bolt is 20mm, and length is 20cm, and model is M16.
Described pre-embedded steel slab is Q235 steel plate, thickness 20mm.
The length of described lacing wire is greater than 50cm, and material is screw-thread steel, and diameter is 20mm.
Described wooden form is wood plywood material, and thickness is 1cm.
The beneficial effects of the utility model are: adopt bolt between pre-embedded steel slab and wooden form, apply a pressure, pre-embedded steel slab and wooden form surface can be tightly affixed, and between nut and wooden form, add billet, the lumps of wood to make it uniform force, avoid pre-embedded steel slab concreting vibrate work progress produce displacement; Further, avoid because of pre-embedded steel slab fix loosely can not be close to template surface produce the artificial chisel that needs remove the operation of pre-embedded steel slab surface concrete; Further, artificial chisel is except after pre-embedded steel slab surface concrete, and pre-embedded steel slab surface will be inconsistent with concrete surface planeness, cause difficulty to later stage welding for steel structure, will avoid the generation of this problem after adopting the utility model.

Detailed description of the invention
Further describe the technical solution of the utility model below, but described in claimed scope is not limited to.
A kind of pre-embedded steel slab being applicable to wooden model as shown in Figure 1 to Figure 3, comprises wooden form 1, pre-embedded steel slab 2, lacing wire 3, bolt 4, the lumps of wood 5, nut 7; Described wooden form 1 and pre-embedded steel slab 2 surface are close to, and wooden form 1 and pre-embedded steel slab 2 are fixed through wooden form 1 and pre-embedded steel slab 2 attaching nut 7 by bolt 4; Described lacing wire 3 welding edges pre-embedded steel slab 2 relative to wooden form 1 another on the surface; The quantity of described lacing wire 3 is more than two; Described wooden form 1 is also fixed with the lumps of wood 5 on the surface, between wooden form 1 and nut 7 relative to another of pre-embedded steel slab 2.
Also comprise billet 6, billet 6 is fixed between nut 7 and the lumps of wood 5; On the contact surface of billet 6 and the lumps of wood 5, billet 6 covers the lumps of wood 5 completely.
