Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated buildings, in particular to a prefabricated hollow shear wall suitable for multi-storey houses. Background Technique

[0002] Driven by the rural revitalization strategy, prefabricated housing, as an innovative building model, is gradually becoming an important trend in housing construction in rural areas.

[0003] Although the existing precast composite shear wall structure does not require manual formwork support and removal operations compared with the traditional cast-in-place process, which reduces a large amount of human and material resources consumption, the pouring process is cumbersome, and the precast solid shear wall structure has a large amount of concrete used, a heavy self-weight of the wall after forming, and is not easy to install. Further, for the multi-storey building structure using solid shear walls, the unit cost is high, which does not meet the requirement of being economical and affordable. Content of the Utility Model

[0004] Aiming at the deficiencies in the existing technology, the utility model provides a prefabricated hollow shear wall suitable for multi-storey houses, which solves the problems of difficult installation and high economic cost caused by the large amount of concrete used in the existing precast solid shear wall structure.

[0005] According to the technical solution of the utility model, a prefabricated hollow shear wall suitable for multi-storey houses includes a wall body, the wall body is divided into concrete inner and outer leaf plates and concrete ribs, the concrete ribs are vertically and fixedly connected to the concrete inner and outer leaf plates, a steel mesh is distributed in the concrete inner and outer leaf plates, the concrete ribs enclose a "field"-shaped pouring cavity and are distributed in the concrete ribs, and a foam board is arranged in the pouring cavity for filling.

[0006] The technical principle of the utility model is as follows: The operator prepares the mold, steel bars, concrete and foam board, first binds the inner steel mesh, then pours the concrete into the mold to form the concrete inner and outer leaf plates and the concrete ribs and compacts them, then arranges the foam board in the hollow area and fixes it, then binds the outer steel mesh, and then uses the truss bars to fix the two layers. The mold is moved under the mixer, and then the concrete is poured for the second time. After coagulation, it is vibrated and compacted again. Different from the pouring process of the traditional precast composite wall panel, the wall panel pouring adopts integral pouring and forming, avoiding the turnover of the mold. Moreover, since the foam board is built in to replace the concrete, the self-weight of the wall is reduced. In this way, the problems of difficult installation and high economic cost caused by the large amount of concrete used in the existing precast solid shear wall structure are solved.

[0007] Compared with the prior art, the utility model has the following beneficial effects: By setting the concrete ribs, the wallboard has a certain integrity even if it is not solid, improving its bearing capacity. At the same time, the built-in foam board replaces the concrete, which can not only meet the strength requirements, but also save the amount of concrete used and reduce the self-weight of the wall. Moreover, compared with the traditional structure of clamping the insulation layer with inner and outer concrete leaf plates, the "grid" structure makes the wall more stable and not easily damaged. In this way, the problems of difficult installation and high economic cost caused by the large amount of concrete used in the prior art of prefabricated solid shear wall structures are solved.

[0014] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further elaborates on the utility model in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0015] The following further explains the technical solutions in the utility model in combination with the drawings and embodiments.

[0016] As Figure 1-5As shown in the figure, an embodiment of the present utility model provides an assembled hollow shear wall applicable to multi-story houses, which includes a wall body 1. The wall body 1 is divided into an inner and outer concrete leaf plates 6 and a concrete rib 7. The concrete rib 7 is vertically and fixedly connected to the inner and outer concrete leaf plates 6. A steel mesh 2 is distributed in the inner and outer concrete leaf plates 6. The concrete ribs enclose a "field"-shaped pouring cavity, which is distributed in the concrete rib 7. A foam board 4 is arranged in the pouring cavity for filling purposes.

[0017] Specific operation process: The operator prepares the mold, steel bars, concrete, and foam board 4. First, tie the inner steel mesh 2, then pour the concrete into the mold to form the inner and outer concrete leaf plates 6 and the concrete rib 7 and compact it. Then, arrange the foam board 4 in the hollow area and fix it, and then tie the outer steel mesh 2. Then, use the truss bars 3 to fix the two layers. Move the mold under the mixer, and then pour the concrete for the second time. After it solidifies, vibrate it again to make it dense. Different from the traditional precast laminated wall panel pouring process, this wall panel pouring adopts an integral pouring and forming method, avoiding the need for mold turning. Moreover, since the foam board 4 is built-in to replace the concrete, the weight of the wall body 1 is reduced. By setting the concrete rib 7, even though the wall panel is not solid, it has a certain integrity, improving its bearing capacity. At the same time, the built-in foam board 4 replaces the concrete, which can not only meet the strength requirements but also save the amount of concrete used and reduce the weight of the wall body 1. In this way, the problems of difficult installation and high economic cost caused by the large amount of concrete used in the assembled solid shear wall structure in the prior art are solved.

[0018] According to another embodiment of the present utility model, as Figure 2 、 5 shown, an assembled hollow shear wall applicable to multi-story houses, a truss bar 3 is connected between the steel meshes 2. The truss bar 3 includes an upper chord bar 12, a lower chord bar 13, and an inclined web bar 14. Two of the lower chord bars 13 are connected to one upper chord bar 12 through the inclined web bar 14, forming a "person"-shaped cross-section when viewed from the cross-section. The truss bar 3 connects the upper and lower layers of the steel mesh 2. The upper chord bar 12 is arranged parallel to the steel mesh 2 of one layer. Two of the lower chord bars 13 are arranged parallel to the steel mesh 2 of the other layer. The lower chord bar 13 and the upper chord bar 12 are connected by the inclined web bar 14, and the inclined web bar 14 forms a "person"-shaped cross-section between the two layers of steel meshes 2.

[0019] According to another embodiment of the present utility model, as Figure 1 shown, an assembled hollow shear wall applicable to multi-story houses, a groove body 5 is reserved at the top of the wall body 1. Concrete can be poured into the groove body 5 to facilitate the connection between the wall bodies 1, making the connection between the walls more convenient and reliable.

[0020] According to another embodiment of the present invention, Figure 1 As shown, a prefabricated hollow shear wall suitable for multi-story buildings has embedded bolts 8 installed on the top and right side of the wall 1, and an embedded bolt box 9 installed on the left side of the wall 1. The vertical seam connection adopts a dry connection method, inserting the embedded bolts 8 on the right side of the wall into the embedded bolt box 9 on the left side of the other wall for connection. The horizontal seam connection adopts a dry and wet connection method, and the connection between the plate and the wall 1 is partially cast in place. The embedded bolts 8 on the upper side of the wall are then inserted into the embedded bolt box 9 on the lower side of the wall on the upper floor for connection.

[0021] According to another embodiment of the present invention, Figure 4 As shown, a prefabricated hollow shear wall suitable for multi-story buildings has a steel mesh 2 divided into two layers, with each layer including transverse reinforcement 10 and vertical reinforcement 11. These reinforcements 10 and 11 are equidistantly arranged and perpendicular to each other within the same plane. This equidistant arrangement ensures sufficient overall support after concrete pouring, preventing partial gaps. Furthermore, concrete ribs 7 can be installed between the upper and lower layers, enhancing the wall panel's integrity and carrying capacity.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting.
