[0025] In addition, the terms "first", "second", "third" and the like are only used to distinguish description, and cannot be understood as indicating or implying relative importance.

[0026] As Figures 1-3As shown, a window sill coping prefabricated component includes a concrete prefabricated block 5 located at the first floor position of the window wall 2 and two groups of reinforcing molds 6 detachably arranged on the outer wall body 1 on both sides of the concrete prefabricated block 5. The length of the concrete prefabricated block 5 is not less than the length of the window wall 2. The prefabricated concrete prefabricated block 5 is directly stacked on the outer wall body 1. The masonry construction of the window wall 2 is carried out above the concrete prefabricated block 5. The partition wall 3 is stacked on the inner side of the outer wall body 1 in which the concrete prefabricated block 5 is stacked, thereby ensuring the synchronous construction of the window wall 2 and the partition wall 3, and avoiding the extension of the construction period. The transverse embedded steel bars 501 are embedded in the concrete prefabricated block 5. The embedded steel bars 501 extend to the reinforcing molds 6 at both ends. The reinforcing steel bars 401 are arranged in the reinforcing molds 6. One end of the reinforcing steel bars 401 is embedded in the bearing column 4 connected with the outer wall body 1. The other end of the reinforcing steel bars 401 is overlapped and tied with the embedded steel bars 501. The window sill coping formed by pouring on the inner side of the reinforcing mold 6 and the concrete prefabricated block 5 form common transverse tensioned steel bars in the form of overlapped steel bars, thereby ensuring the overall forming strength and the uniformity of settlement of the window sill coping.

[0027] Further preferably, in order to guide the rainwater flowing through the window sill coping out of the window sill and prevent the rainwater from flowing back to the window sill, as shown, Figure 5 As shown, the side of the concrete prefabricated block 5 away from the partition wall 3 is provided with a water guide inclined surface 502. The water guide inclined surface 502 is inclined downward along the upper surface of the concrete prefabricated block 5. The height of the water guide inclined surface 502 is not more than 1 / 4 of the height of the concrete prefabricated block 5. The width of the water guide inclined surface 502 is not more than 1 / 5 of the height of the concrete prefabricated block 5.

[0028] Further preferably, the number of the embedded steel bars 501 and the reinforcing steel bars 401 is three. The embedded steel bars 501 and the reinforcing steel bars 401 are arranged side by side along the width direction of the concrete prefabricated block 5. The type of the embedded steel bars 501 and the reinforcing steel bars 401 is one or more of HRB400, HRBF400 and RRB400. In order to ensure that the strength grade of the window sill coping formed by pouring concrete reaches the required C25 grade, the required overlapped length of the transverse tensioned steel bars, i.e. the overlapped and tied length of the embedded steel bars 501 and the reinforcing steel bars 401, is not less than 64 times the diameter of the embedded steel bars 501. In the embodiment, the diameter of the embedded steel bars 501 is 6mm. The above-mentioned overlapped length of the steel bars is greater than or equal to 384mm.

[0029] As shown, Figure 3 and Figure 4As shown, the reinforcing mold 6 comprises a formwork 601 on both sides of the outer wall body 1, a plurality of clamping plate groups distributed along the length direction of the formwork 601 outside the two formworks 601, and the clamping plates 602 of each clamping plate group are fixedly connected at positions above the formwork 601 through the tensioning bolts 603 and the locking nuts 604. The tensioning bolts 603 are located above the formwork 601, and the clamping plate groups achieve the effect of clamping the formwork 601, compared with the traditional punching and screwing reinforcement method of the formwork 601, the formed window sill coping does not need to be repaired, and the sealing effect is good. Further preferably, the distance between the upper end of the formwork 601 and the outer wall body 1 is equal to the height of the concrete prefabricated block 5, so that the window sill coping of the concrete prefabricated block 5 is directly poured and formed in the formwork 601.

[0030] Further preferably, in order to improve the stability of the reinforcing mold 6, the upper ends of the clamping plates 602 of each clamping plate group are provided with a connecting plate 605, the two ends of the connecting plate 605 are connected with the clamping plates 602 through rotating nails, and two vertically arranged keels 606 are fixed outside the formwork 601, and the clamping plates 602 of each clamping plate group are clamped and connected with the formwork 601 through the keels 606, so as to ensure the firmness of the formwork 601.

[0031] When the above technical solution is implemented, the formwork 601 is used to preform a concrete prefabricated block 5 with three embedded steel bars 501, which has a size of 100*300*1000mm, so as to match the construction of a 1m window wall 2, and the formed concrete prefabricated block 5 has a water guide inclined surface 502 with a height of 20mm and a width of 50mm, after the above concrete prefabricated block 5 is stacked at the construction position of the window wall 2, the synchronous masonry construction of the window wall 2 and the partition wall 3 can be carried out, which does not affect the construction period of the wall body, such as Figure 1 and Figure 2 As shown, the construction personnel simultaneously implant reinforcing steel bars 401 corresponding to the embedded steel bars 501 of the concrete prefabricated block 5 in the load-bearing column 4, use iron wires to bind the reinforcing steel bars 401 and the embedded steel bars 501 that are overlapped together, and install the reinforcing mold 6 on both sides of the outer wall body 1, one end of the formwork 601 in the reinforcing mold 6 abuts against the load-bearing column 4, and the other end extends to the outside of the concrete prefabricated block 5, and then the concrete is poured into the reinforcing mold 6, after the concrete is solidified, the mold is removed, the construction of the window sill coping is completed, the window sill coping and the concrete prefabricated block 5 share the horizontal reinforcing bars, and the overall forming strength and the settlement uniformity are ensured.

[0032] The above only describes preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
