Description

Technical Field

[0001] This invention belongs to the field of prefabricated building technology, specifically relating to an industrialized prefabricated eaves gutter retaining wall for pitched roofs without formwork support. Background Technology

[0002] During the construction of prefabricated buildings, structures such as eaves gutters and retaining walls on the top floor are not suitable for large-scale prefabrication due to the different top-floor designs of various buildings. Currently, they are mostly constructed using cast-in-place methods.

[0003] When constructing existing eaves gutter retaining walls, it is usually necessary to first build a wall of a certain height by pouring or bricklaying, then tie steel bars on top of the wall and set up formwork according to the sloping roof before pouring the retaining beam (horizontal beam), or after pouring or bricklaying the wall, erect the retaining beam on the wall, then place the sloping roof purlins on the retaining beam at an angle, and then fill the gap between the purlins and the retaining beam with bricks. Both of these construction methods are relatively complicated, have low construction efficiency, and poor safety. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an industrialized prefabricated eaves gutter retaining wall for pitched roofs that does not require formwork, adopts a prefabricated structure, can be assembled and installed, and facilitates improved construction efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0006] An industrialized, formwork-free prefabricated eaves gutter retaining wall for pitched roofs includes an embedded horizontal beam. An inner formwork frame is provided on the inner side of the embedded horizontal beam, and an outer formwork frame is provided on the outer side of the embedded horizontal beam. A top formwork frame, inclined downwards from the inside to the outside, is formed between the top of the inner and outer formwork frames, with the inclination of the top formwork frame matching the inclination of the pitched roof. A horizontally arranged bottom formwork frame is formed between the bottom of the inner and outer formwork frames. Stepped side formwork frames are formed between the left and right ends of the inner and outer formwork frames, respectively. An empty column-beam connection area is formed between the side formwork frames and the outer formwork frame.

[0007] The inner mold frame, outer mold frame, top mold frame, bottom mold frame, and side mold frame are each covered with steel mesh, and the steel mesh on each mold frame together form a wall filling cavity. At least one of the steel meshes has a pouring port that communicates with the wall filling cavity. The two ends of the embedded beam are prefabricated with column-beam connecting plates extending into the column-beam joint area. The top mold frame is prefabricated with a first connector for connecting with the roof panel.

[0008] As a preferred technical solution, the end of the inner mold frame is provided with a splicing baffle that seals the column-beam joint area and facilitates splicing with the adjacent eaves gutter retaining wall.

[0009] As a preferred technical solution, the side mold frame is prefabricated with a sealing nut, and the splicing baffle is connected to the side mold frame by bolts.

[0010] As a preferred technical solution, the embedded crossbeam is an I-beam or a rectangular beam.

[0011] As a preferred technical solution, the inner mold frame is prefabricated with a second connector for connecting to the roof panel.

[0012] As a preferred technical solution, the inner mold frame includes two horizontal keels, one above the other, and several vertical keels are arranged between the two horizontal keels.

[0013] As a preferred technical solution, the longitudinal keel includes a coarse longitudinal keel and a fine longitudinal keel, which are arranged alternately, and the coarse longitudinal keel also serves as the second connecting member.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects:

[0015] (1) A retaining wall skeleton structure is formed by embedded beams, inner mold frames, outer mold frames, top mold frames, bottom mold frames, and side mold frames. Each of the inner mold frames, outer mold frames, top mold frames, bottom mold frames, and side mold frames is covered with steel mesh. The steel mesh on each mold frame together encloses a wall filling cavity. At least one of the steel meshes has a pouring port communicating with the wall filling cavity. Thus, after lightweight aggregate concrete is poured into the wall filling cavity in the factory, a single eaves gutter retaining wall can be formed. The inclination of the top mold frame is consistent with the inclination of the sloping roof. The top formwork frame is prefabricated with a first connector for connecting to the roof panel, which allows for quick assembly and connection of the eaves gutter retaining wall and the roof panel. Since the side formwork frame is stepped, an empty column-beam connection area is formed between the side formwork frame and the outer formwork frame. The two ends of the embedded beam are prefabricated with column-beam connecting plates extending into the column-beam connection area. In this way, by setting up the column-beam connection area, the embedded beam and the structural column can be quickly assembled and connected through the column-beam connecting plates, which also realizes the assembly connection of the individual eaves gutter retaining wall and the structural column, making construction quick and convenient.

[0016] (2) The end of the inner mold frame is equipped with a splicing baffle that seals the column-beam joint area and facilitates splicing with the adjacent eaves gutter retaining wall. After the adjacent eaves gutter retaining walls are connected to the structural columns, the column-beam joint area can be sealed and covered by the splicing baffle. Then, insulation material can be filled to achieve a seamless connection between the adjacent eaves gutter retaining walls.

[0017] (3) The eaves gutter retaining wall adopts a prefabricated structure, which facilitates industrialized and modular production, integrates the surrounding beam and the wall into one, and does not require on-site formwork, making assembly and construction convenient.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0028] like Figure 1 , Figure 2 and Figure 7As shown, the industrialized prefabricated eaves gutter retaining wall for pitched roofs without formwork includes an embedded horizontal beam 1, which can be an I-beam or a rectangular steel beam. An inner formwork frame 2 is provided on the inner side of the embedded horizontal beam 1, and an outer formwork frame 3 is provided on the outer side of the embedded horizontal beam 1. A top formwork frame 4 is formed between the top of the inner formwork frame 2 and the outer formwork frame 3, which is inclined downward from the inside to the outside. The inclination of the top formwork frame 4 is consistent with the inclination of the pitched roof. A bottom formwork frame 5 is formed between the bottom of the inner formwork frame 2 and the outer formwork frame 3. Stepped side formwork frames 6 are formed between the left end of the inner formwork frame 2 and the right end of the outer formwork frame 3. An empty column-beam joint area 7 is formed between the side formwork frame 6 and the outer formwork frame 3.

[0029] The inner mold frame 2, outer mold frame 3, top mold frame 4, bottom mold frame 5, and side mold frame 6 are each covered with steel mesh 8 (for reference). Figure 3 (The steel mesh 8 is only partially shown in the diagram). The steel meshes on each mold frame together enclose the wall filling cavity. At least one of the steel meshes 8 has a pouring port 9 that communicates with the wall filling cavity. In this way, after pouring lightweight aggregate concrete into the wall filling cavity in the factory, a single eaves gutter retaining wall can be formed.

[0030] refer to Figure 1 and Figure 4 The embedded beam 1 has prefabricated column-beam connecting plates 10 extending into the column-beam junction area 7 at both ends. Thus, by setting the column-beam junction area 7 and using the column-beam connecting plates 10, a prefabricated connection between the embedded beam 1 and the structural column 12 can be quickly achieved (see reference). Figure 6 This means that the prefabricated connection between the individual eaves gutter retaining wall and the structural column is achieved, making construction quick and convenient. (Reference) Figure 2 and Figure 8 Since the inclination of the top mold frame 4 is consistent with the inclination of the sloping roof, the top mold frame 4 is prefabricated with a first connector 11 for connecting with the roof panel 13. The pre-reserved first connector 11 facilitates the quick assembly connection between the eaves gutter retaining wall and the roof panel 13.

[0031] refer to Figure 5 and Figure 6 The inner mold frame 2 is fitted with a splicing baffle 14 at its end to seal the column-beam junction area 7 and facilitate splicing with adjacent eaves gutter retaining walls. The side mold frame 6 has two or three levels of steps. The space at the inner step facilitates the installation of the splicing baffle 14, while the space at the outer step forms the column-beam junction area 7. The side mold frame 6 is pre-fabricated with sealing nuts, so that the splicing baffle 14 and the side mold frame 6 can be quickly connected by bolts. After the adjacent eaves gutter retaining walls are connected to the structural columns 12, the column-beam junction area 7 can be sealed and covered by the splicing baffle 14, and then insulation material can be filled to achieve a seamless connection between the adjacent eaves gutter retaining walls.

[0032] The inner mold frame 2 is prefabricated with a second connector for connecting with the roof panel 13. In this way, when the height of the retaining wall is greater than 600mm, the second connector can be used to achieve auxiliary reinforcement and support between the retaining wall and the roof panel 13.

[0033] refer to Figure 3 In this embodiment, the inner frame 2 includes two horizontal keels 21, and several longitudinal keels are arranged between the two horizontal keels 21. The longitudinal keels include thick longitudinal keels 22 and thin longitudinal keels 23. The thick longitudinal keels 22 and thin longitudinal keels 23 are arranged alternately. In this way, the thick longitudinal keel 22 can directly serve as the second connector. During installation, the connector for assembly is directly connected to the second connector by bolts, which can effectively realize the auxiliary reinforcement and support of the retaining wall and the roof panel 13. The structure is simple and practical.

[0034] The eaves gutter retaining wall adopts a prefabricated structure, which facilitates industrialized and modular production. The eaves gutter retaining wall directly integrates the surrounding beam and the wall into one piece, eliminating the need for on-site formwork and making assembly and construction convenient.

[0035] The above description is merely an illustrative embodiment of the present invention and is not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention.
