[0029] Furthermore, the anchor hole and the anchor groove 104 are filled with anchoring agent. Figure 2 As shown, the anchor hole and the anchor groove 104 are filled with anchoring agent, and the anchoring agent in the anchor groove 104 is filled to be flush with the inner side surface of the first side plate 102, which can not only increase the connection strength between the chemical anchor 3 and the first side plate 102, but also avoid the chemical bolts, chemical anchor nuts 4, the first embedded steel plate 105, etc. from being exposed to air and water for a long time, thereby extending the service life of the chemical bolts and improving the stability and durability of the structure.

[0030] The above embodiment is optimized, the bottom of the anchor groove 104 is pre-buried with a first pre-buried steel plate 105, the head of the chemical anchor 3 is fixed to the first pre-buried steel plate 105 through the chemical anchor nut 4, and the tail of the chemical anchor 3 passes through the first pre-buried steel plate 105 and extends into the anchor hole.

A perfusion hole 109 is provided on the top surface of the first side plate 102, and the perfusion hole 109 extends downward to communicate with the anchor hole. When the upper and lower anchor holes are on the same vertical plane, the perfusion hole 109 extends downward from the top surface of the first side plate 102 to the upper anchor hole, and then extends downward to the lower anchor hole. The anchoring agent can be perfused into the upper and lower anchor holes through the perfusion hole 109. The anchoring agent in the anchor groove 104 can be filled on the inner side of the first side plate 102.

[0033] In this embodiment, a plurality of longitudinal bars and a plurality of stirrups are provided in the bottom plate 101, the first side plate 102 and the second side plate 103, and the longitudinal bars in each part are connected by stirrups, and the longitudinal bars at the connection between the side plate and the bottom plate 101 are respectively connected to the stirrups in the two plates.

[0034] like Figure 5-Figure 6 As shown, the splicing end edge of the bottom plate 101 is recessed downward to form a recessed portion 106, and the recessed portions 106 of the adjacent drainage gutter prefabricated components 1 are arranged opposite to each other to form a splicing groove, in which a connecting steel plate 8 is arranged, and the two ends of the connecting steel plate 8 are respectively fixed to the bottom surfaces of the recessed portions 106 on both sides.

By arranging the connecting steel plate 8 in the splicing groove, and fixing the two ends of the connecting steel plate 8 to the recessed portions 106 of the two drainage gutter prefabricated components 1, the splicing of the two drainage gutter prefabricated components 1 is achieved, thereby improving the integrity of the assembled drainage gutter.

[0035] In one embodiment, an embedded sleeve 108 is embedded in the bottom plate 101 below the recessed portion 106, and the connecting steel plate 8 is connected to the embedded sleeve 108 through a connecting bolt 9. The connecting steel plate 8 is provided with a hole for the connecting bolt 9 to pass through, and the connecting bolt 9 passes through the connecting steel plate 8 and is connected to the embedded sleeve 108, thereby fixing the connecting steel plate 8 in the recessed portion 106 of the bottom plate 101.

[0037] Furthermore, the recessed portion 106 is filled with an anchoring agent. Figure 6 As shown, the recessed portion 106 is filled with an anchoring agent until it is flush with the top surface of the base plate 101. On the one hand, this can prevent the connecting bolts 9, the connecting steel plate 8 and the second embedded steel plate 107 from being exposed to air and water for a long time, thereby extending the service life of the connecting bolts 9 and the connecting steel plate 8 and maintaining the connection strength and stability. On the other hand, the anchoring agent has higher strength and adhesion after solidification, further improving the stability of the structure.

[0038] In one embodiment, the height of the second side plate 103 is lower than the height of the first side plate 102. The drainage gutter prefabricated member 1 of this embodiment is a U-shaped structure, and the height of the second side plate 103 away from the PTW wall 2 is lower than the height of the first side plate 102 close to the PTW wall 2, which helps to enhance the stability of the overall structure and can also better adapt to the outline of the building.

[0039] In this embodiment, the drainage gutter is modularly manufactured in the factory in advance, and then the drainage gutter prefabricated member 1 is transported to the construction site for assembly. During the assembly of the drainage gutter prefabricated member 1, it is necessary to first fix a set of triangular brackets 5 on the PTW wall 2 as temporary support, and then remove the triangular brackets 5 after the drainage gutter prefabricated member 1 is fixed on the PTW wall 2. The triangular brackets 5 can be reused, saving the template support cost.

[0040] In one embodiment, the triangular bracket 5 includes two horizontal bars 501, two vertical bars 502, two vertical bars 503 and two diagonal braces 504. The two horizontal bars 501 and the two vertical bars 502 are connected to form a rectangular frame, and the two corners of the rectangular frame close to the PTW wall 2 are respectively connected to one end of the two vertical bars 503, and the two corners of the rectangular frame away from the PTW wall 2 are respectively connected to the other ends of the two vertical bars 503 through the two diagonal braces 504. Among them, the horizontal bars 501, the vertical bars 502, the vertical bars 503 and the diagonal braces 504 can all be made of steel.

[0041] Furthermore, a fixing steel plate 505 is welded to the top of each vertical rod 503, and the fixing steel plate 505 is detachably connected to the PTW wall 2 via detachable connectors 506 on both sides of the vertical rod 503. Specifically, the detachable connector 506 can adopt a matching structure of bolts and sleeves, and when the PTW wall 2 is prefabricated, the sleeve 108 is embedded at the corresponding position of the prefabricated wall panel 201, and when the triangular bracket 5 is manufactured, the hole for the bolt to pass is reserved at the corresponding position on the fixing steel plate 505, and before the drainage gutter prefabricated component 1 is assembled, the bolts are passed through the holes on the fixing steel plate 505 and screwed into the corresponding embedded sleeves 108, so that the triangular bracket 5 is stably fixed on the PTW wall 2; after the drainage gutter prefabricated component 1 is assembled, the triangular bracket 5 is separated from the PTW wall 2 by screwing out the bolts, and then recycled.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
