the first prefabricated part body and the second prefabricated part body are oppositely arranged and enclosed to form a preformed hole, and the preformed hole concrete structure is formed by pouring once after the prefabricated parts of the concrete preformed hole are fixed;
and the post-pouring layer is poured on the surface layer of the concrete structure with the reserved hole.
Preferably, the areas of the bottom surfaces of the prefabricated parts of the concrete preformed holes are larger than the areas of the top surfaces of the prefabricated parts.
Preferably, the first prefabricated part body and the second prefabricated part body are both made by demolding of a mold.
Preferably, the longitudinal sections of the first prefabricated part body and the second prefabricated part body are both right-angled trapezoids.
Preferably, the first prefabricated part body and the second prefabricated part body are bonded into a whole through structural adhesive.
Preferably, the precast concrete preformed hole component is of a wedge-shaped structure.
The beneficial effects of the utility model reside in that:
1. the utility model adopts the concrete preformed hole prefabricated component which is firmly fixed before the foundation is poured and can be directly used after the foundation is poured without disassembling and assembling the mould;
2. the concrete preformed hole prefabricated component in the utility model is of a wedge-shaped structure, thereby ensuring that the structure of the preformed hole can not be damaged when the structure such as a screw is pulled out of the concrete structure of the preformed hole;
3. the utility model discloses make things convenient for the site operation to pour the equipment basis, avoid the manual work to disassemble the mould in narrow and small preformed hole, greatly improved work efficiency, facilitate promotion.

fig. 2 is the utility model discloses well concrete preformed hole prefabricated component's schematic structure.
Description of reference numerals:
1-precast concrete preformed hole member, 110-first precast member body, 120-second precast member body;
2-a preformed hole concrete structure and 3-a post-cast layer.
Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.
As shown in fig. 1-2, in particular, a novel concrete preformed hole structure comprises a concrete preformed hole prefabricated part 1, a preformed hole concrete structure 2 and a post-cast layer 3;
the precast concrete component 1 comprises a first precast component body 110 and a second precast component body 120, wherein the first precast component body 110 and the second precast component body 120 are both in a U-shaped groove structure;
the first prefabricated part body 110 and the second prefabricated part body 120 are oppositely arranged and enclosed to form a preformed hole, and the preformed hole concrete structure 2 is formed by one-time pouring after the concrete preformed hole prefabricated part 1 is fixed;
and the post-cast layer 3 is poured on the surface layer of the reserved hole concrete structure 2.
According to the structure, the post-cast layer 3 is used for mending the reserved holes, and the post-cast layer 3 is formed by secondary casting after the concrete structure 2 with the reserved holes is cast.
Specifically, the areas of the bottom surfaces of the concrete preformed hole prefabricated parts 1 are all larger than the areas of the top surfaces.
Specifically, the longitudinal sections of the first prefabricated part body 110 and the second prefabricated part body 120 are both right-angled trapezoids.
Preferably, the precast concrete member 1 with a preformed hole has a wedge-shaped structure.
By adopting the structure, the structure of the reserved hole can not be damaged when the structure such as a screw and the like is pulled out from the concrete structure 2 of the reserved hole.
As another specific solution, the first prefabricated part body 110 and the second prefabricated part body 120 are both made by demolding from a mold.
Before the construction, make a plurality of concrete preformed hole prefabricated component 1 through the mould, convenient and fast has reduced the work of carrying out the mould and demolising in the preformed hole, is subject to the space in the preformed hole, and the work of demolising the template is hardly gone on, has increased the construction degree of difficulty.
