[0002] In the construction of multi-story and high-rise buildings, as a way to transfer the upper and lower axes of the floors, it is often necessary to reserve holes for laying out lines at appropriate locations on the floor slab. The traditional laying out holes and their closure generally follow the following three steps: 1. Openings are made in the flat formwork of the floor slab, and wooden or aluminum formwork is used to support the formwork and pour the floor slab concrete; 2. After the floor slab is poured and the laying out holes are formed, the laying out holes are covered with wooden formwork or flip-top iron sheets to ensure safe and civilized construction; 3. After the use of the laying out holes, formwork is supported below the opening of the laying out holes, and concrete is poured to seal the laying out holes. If necessary, reinforcement is required on the sides. The processing of the existing laying out holes in multi-story or high-rise buildings is cumbersome and time-consuming.
[0003] However, the prior art still has the following problems:
[0004] Firstly, when sealing the wiring holes of buildings in the prior art, most of the sealing structures are too complicated to seal the wiring holes, which results in a lot of time spent on sealing the wiring holes, thereby increasing the difficulty of the workers' work.
[0005] Secondly, when the conventional building wiring hole plugging structures are used to plug the wiring holes, most of the plugging structures cannot quickly plug the wiring holes, resulting in too low plugging efficiency of the wiring holes, thereby increasing the engineering time for plugging the wiring holes.
[0006] In view of the above problems, the inventor proposes a plugging structure for wiring holes in building construction to solve the above problems. Utility Model Content

When laying out the wires, the prefabricated block 15 is put forward to form a wire-laying hole; after the wire-laying hole is finally used, the prefabricated block 15 is finally embedded in the concrete wire-laying hole with the bonding mortar 14. The bonding mortar 14 cooperates with the concave and convex surface left by the non-bursting grouting tape 3 to better adhere and fix the prefabricated block 15 and the wire-laying hole to permanently seal the wire-laying hole. The lower part of the prefabricated block 15 is flush with the bottom of the concrete floor slab 16, and the upper part is flush with the upper end of the concrete floor slab 16, thereby realizing that the sealing structure can quickly seal the wire-laying hole.

[0034] Working principle: When the sealing structure needs to seal the layout hole, a square hole 8 is opened in the floor template 12, and a steel inverted cone mold 1 is provided. The steel inverted cone mold 1 is installed in the square hole 8 through the handle 4 to seal the square hole 8. At the same time, anti-chisel grouting tape 3 is respectively pasted on the four sides inside and outside the steel inverted cone mold 1. A steel mesh 2 and a cushion block 13 are pre-buried in the cavity of the steel inverted cone mold 1 to increase the strength of the prefabricated block 15 to be formed. A nylon belt is fastened to the steel mesh 2 in the steel inverted cone mold 1. Concrete 7 is poured on the floor template 12 and in the cavity of the steel inverted cone mold 1 respectively. At the same time, concrete 7 is poured in the steel inverted cone mold 1 to consolidate and form a prefabricated block 15. The thickness of the prefabricated block 15 is equal to the thickness of the floor template 12. The steel inverted cone mold 1 is taken out of the floor template 12 to form a wire-laying hole, and the non-chisel grouting belt 3 is removed.

The shape and size of the concrete prefabricated block 15 are the same as the thickness of the floor template 12. The shape and size of the wire hole are adapted to each other, so that the blocking structure can make the construction of blocking the wire-laying hole more convenient. When the wire-laying hole needs to be quickly blocked, the prefabricated block 15 is usually placed in the hole to ensure safe and civilized construction. When laying out the wire, the prefabricated block 15 is put forward to form the wire-laying hole; after the wire-laying hole is finally used, the prefabricated block 15 is embedded in the square hole 8 with the bonding mortar 14. The bonding mortar 14 cooperates with the concave and convex surface left by the non-bursting grouting tape 3 to better adhere and fix the prefabricated block 15 and the wire-laying hole to permanently block the wire-laying hole. The lower part of the prefabricated block 15 is flush with the bottom of the concrete floor slab 16, and the upper part is flush with the upper end of the concrete floor slab 16, so that the blocking structure can quickly block the wire-laying hole.
