[0019] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.
[0020] like Figures 1 to 4As shown, the industrialized formwork-free light aggregate prefabricated eaves gutter retaining wall floor slab includes a floor slab formwork 10 and a retaining wall formwork 20, and the floor slab formwork 10 and the retaining wall formwork 20 are connected by a connector 30; the floor slab formwork 10 and the retaining wall formwork 20 are respectively prefabricated with a steel skeleton 40, and the steel skeleton 40 is formed by binding a plurality of transverse steel bars and longitudinal steel bars; the inner and outer sides of the retaining wall formwork 20 are respectively covered with steel plate mesh 50, and the retaining wall formwork 20 and the steel plate mesh 50 are enclosed together to form a wall filling cavity, and a pouring port 21 connected to the wall filling cavity is opened on the upper part of the retaining wall formwork 20, and light aggregate concrete can be poured into the wall filling cavity of the retaining wall formwork from the pouring port 21. Since the floor slab formwork 10 is horizontally arranged, there is no need to cover the upper and lower surfaces with steel plate mesh. When pouring light aggregate concrete, it is only necessary to lay a layer of isolation membrane at the bottom of the floor slab formwork 10, and the upper part is smoothed after being poured.
[0021] refer to Figure 5 The steel skeleton in the floor slab formwork 10 and the steel skeleton in the retaining wall formwork 20 have a plurality of interconnected steel bars 41, which play a role of sharing and connecting in the two skeletons. After pouring lightweight aggregate concrete, the overall structural strength of the floor slab and the eaves gutter retaining wall can be improved.
[0022] refer to Figure 1 The floor formwork 10 is composed of two transverse cold-bent thin-walled steel sections 11 and two longitudinal cold-bent thin-walled steel sections 12. Figure 3 , the outer side walls of the transverse cold-bent thin-walled steel 11 and the longitudinal cold-bent thin-walled steel 12 are respectively concavely formed with structural grooves 13. The structural grooves 13 are preferably two and are arranged in an upper and lower distribution. By providing the structural grooves 13, on the one hand, the strength of the cold-bent thin-walled steel body can be improved, and on the other hand, water-swellable rubber strips and sound insulation rubber strips can be embedded in the grooves to ensure the sealing when adjacent floor slabs are assembled and spliced. The bottom of the retaining wall formwork 20 shares a transverse cold-bent thin-walled steel with the floor slab formwork 10, and the two sides and top of the retaining wall formwork 20 are also made of cold-bent thin-walled steel.
[0023] refer to Figure 6 and Figure 7The connecting member 30 includes a transverse connecting plate 31 and a longitudinal connecting plate 32. The transverse connecting plate 31 and the longitudinal connecting plate 32 are an integral structure. Vertical connecting plates 33 are welded to both sides of the transverse connecting plate 31. Reinforcing ribs 34 are arranged between the vertical connecting plates 33 on both sides. Connecting holes 35 are respectively opened on the transverse connecting plate 31, the longitudinal connecting plate 32 and the vertical connecting plate 33. In this way, the transverse connecting plate 31 is fixedly connected to the transverse cold-bent thin-walled steel 11 of the floor formwork 10, the longitudinal connecting plate 32 is fixedly connected to the longitudinal cold-bent thin-walled steel 12 of the floor formwork 10, and the vertical connecting plates 33 on both sides are fixedly connected to the retaining wall formwork 20, thereby realizing a reliable and stable connection between the floor formwork 10 and the retaining wall formwork 20, and the structural design is simple and reliable.
[0024] The structural design of the utility model is simple and reasonable. The floor slab and the eaves gutter retaining wall are directly prefabricated into an integrated structure in the factory. Through the design of the retaining wall formwork frame and the steel plate mesh, no formwork is required during the pouring operation of the eaves gutter retaining wall or on-site construction, which is beneficial to improving construction efficiency and shortening the construction period. At the same time, the construction safety is good and it is suitable for promotion and application in prefabricated buildings.
[0025] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
