AI Technical Summary
In the existing technology, the construction process of cast-in-place capping at the window sill position is complicated, which affects the masonry progress and poses quality risks. It is difficult to achieve efficient and safe window sill capping construction with the existing technology.
Prefabricated concrete blocks are equipped with top reinforcement, which are embedded in the blocks and manufactured at the same time as the concrete blocks to ensure that the top reinforcement extends beyond the sides of the blocks. Positioning saddles are set on the sides for positioning, so that the window sill can be completed in one-time masonry.
Efficient construction at the window sill position was achieved, intermediate waiting time was avoided, construction efficiency was improved, quality risks were reduced, and the continuity and safety of construction were ensured.

[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.
[0021] Please refer to Figs. 1-3 A reinforced concrete component for fabricated building, comprising a concrete precast block 1 precasted by concrete, a plurality of top pressing reinforcements 2 are arranged in the concrete precast block 1, one end of each top pressing reinforcement 2 exceeds the side surface of the concrete precast block 1, the number of the top pressing reinforcements 2 is two, the top pressing reinforcements 2 are precasted simultaneously with the concrete precast block 1, the length of the concrete precast block 1 and the top pressing reinforcements 2 in the same direction is not less than 250mm, and the length of the top pressing reinforcements 2 exceeding the side surface of the concrete precast block 1 is not less than 200mm.
[0022] Specifically, the window sill position wall construction procedure in the embodiment is as follows:
[0023] S1: prefabricating the concrete prefabricated block 1, manufacturing a mold matched with the wall to be built, and prefabricating the concrete prefabricated block 1 by embedding two top pressing reinforcements 2 in the concrete prefabricated block 1 during prefabrication;
[0024] S2: installing the concrete prefabricated block 1 at the window sill position when building the wall, such as Fig. 3 , the top pressing reinforcements 2 of the two concrete prefabricated blocks 1 are placed opposite to each other, and then the wall above is completely built;
[0025] S3: window sill top pressing formwork, binding reinforcement and overlapping with the top pressing reinforcement 2, and finally pouring C25 concrete.
[0026] The width of the concrete prefabricated block 1 is the same as the wall thickness, the height is the same as the window sill top pressing thickness, and the length is greater than 250 mm, which ensures the connectivity of the poured top pressing and the wall. The top pressing reinforcement 2 has the same specification as the window sill top pressing reinforcement, and the reserved length of the top pressing reinforcement 2 is greater than 200 mm, which satisfies the reinforcement overlapping of the top pressing.
[0027] As a technical optimization scheme of the utility model, the side surface of the two top pressing reinforcements 2 in the concrete prefabricated block 1 is provided with a plurality of positioning horse stools 3, the positioning horse stools 3 are used for positioning the top pressing reinforcement 2 at the middle position of the concrete prefabricated block 1, the number of the positioning horse stools 3 is four, the positioning horse stools 3 are welded or bound on the side surface of the top pressing reinforcement 2, and the positioning horse stools 3 are in U shape.
[0028] Specifically, when the concrete prefabricated block 1 needs to be manufactured, first, a mold (such as a formwork) is manufactured according to the size of the concrete prefabricated block 1, and a matched positioning horse stool 3 is manufactured. When the concrete prefabricated block 1 is prefabricated, the positioning horse stool 3 and the top pressing reinforcement 2 are bound or welded.
