Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.
Example one
As shown in fig. 1, the present embodiment discloses a formwork device for a concrete pouring preformed hole, which includes a hole supporting plate 1, wherein the hole supporting plate 1 is circular in the present embodiment. A notch 101 is arranged on the circular hole supporting plate 1, and a detachable loose piece 2 which forms a closed graph with the shape of the hole supporting plate 1 is arranged at the notch 101. Both sides of breach 101 all are provided with curb plate 3, and the tip of curb plate 3 all welds on the inner wall of hole fagging 1, and loose piece 2 passes through 4 tight connections of pendant and between two curb plates 3.
The pendant 4 includes two bolts 401 of arranging side by side, and two bolt 401's screw thread end all run through behind the preformed hole on two curb plates 3 with corresponding nut 402 threaded connection, all overlap on two bolts 401 and be equipped with link 403, and link 403 fixes on loose piece 2. Screwing the nut 402 drives the two side plates 3 to clamp the middle loose piece 2.
Be provided with at least a set of overlap plate group 5 between two curb plates 3, overlap plate group 5 is including welding the overlap plate monomer 501 on two curb plates 3 respectively, the front end portion coincidence of two overlap plate monomers 501, and all be provided with through-hole 502 on two overlap plate monomers 501, after screwing nut 402 and drive the loose piece 2 of two curb plates 3 clamp centre, through-hole 502 corresponds each other on two overlap plate monomers 501, at this moment, run through-hole 502 through bolt assembly or round pin axle, make two overlap plate monomers 501 link together, thereby strengthen two curb plates 3 and holistic structural strength. In this embodiment, the number of the through holes 502 on each single overlapping plate 501 is one, and besides this embodiment, the number of the through holes 502 on each single overlapping plate 501 may be plural.
In order to further improve the overall structural strength, in this embodiment, one side of each side plate 3 is provided with a plurality of reinforcing plates 6, one end of each reinforcing plate 6 is welded on the corresponding side plate 3, and the other end is welded on the inner wall of the hole supporting plate 1.
In this embodiment, the both ends face of hole fagging 1 is the parallel and level terminal surface, and this kind of structure is applicable to wall or prefabricated component and pours the reservation for planar hole. When the hole supporting plate is used, the end face of the hole supporting plate 1 is flush with the outer surface of a wall body or a prefabricated part.
As shown in fig. 2, the utility model is used as follows:
before the holes are poured, the reinforcing mesh 8 is erected, the wall formwork 7 is arranged around the reinforcing mesh 8, the holes are reserved in the reinforcing mesh 8, the hole supporting plate 1 is placed in the holes, one end face of the hole supporting plate 1 is attached to one side wall formwork 7, and the hole supporting plate 1 penetrates through the through hole 502 through a pin shaft or a bolt assembly and then is fixed on the wall formwork 7.
After pouring and solidifying, the bolt 401, the nut 402 and the pin shaft of the connecting through hole 502 are taken down, the movable block 2 is knocked by using tools such as a hammer, the movable block 2 moves along one side, the movable block 2 can be taken down, and the hole supporting plate 1 can be separated from the reserved hole by enabling the two side plates 3 to be close together due to certain elasticity of the hole supporting plate 1.
Example two
As shown in fig. 3, in this embodiment, both end surfaces of the hole supporting plate 1 are arc surfaces, and this structure is suitable for a wall surface or a prefabricated component to be a planar hole pouring reservation. The rest of the structure is identical to the first embodiment, and is not described herein again. It should be noted that, in this embodiment, since both end surfaces of the hole supporting plate 1 are arc surfaces, in the casting mode, the wall form to be cast around should be arc.
The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should also be able to make various modifications and improvements to the technical solution of the present invention without departing from the spirit of the present invention, and all such modifications and improvements are intended to fall within the scope of the present invention as defined in the appended claims.
