Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a cavity device used for constructing a wall in an assembled structure. Background Art

[0002] With the rapid development of modern building industrialization, prefabricated buildings, as a new type of building model, have attracted widespread attention due to their significant advantages such as high efficiency, energy saving, and environmental protection. Prefabricated buildings use factory-prefabricated components and assemble and install them on site, which greatly shortens the construction period, improves the construction quality, and significantly reduces the impact on the environment. However, in the process of promoting and applying prefabricated buildings, the problems existing in traditional prefabricated walls have gradually become prominent.

[0003] Traditional prefabricated walls mainly use reinforced concrete or steel structures. Although these structures have high strength and stability, they are heavy. This not only increases the difficulty of hoisting and transportation costs during construction, but also reduces installation efficiency and increases construction period. In addition, overweight walls may also lead to insufficient bearing capacity of the foundation, posing a potential threat to the safety of the building structure. Utility Model Content

[0004] The purpose of the utility model is to provide a cavity device for constructing a wall in an assembled structure, so as to solve the technical problem in the prior art that the prefabricated wall itself is heavy, which not only increases the difficulty of lifting and transportation costs during the construction process, but also reduces the installation efficiency and increases the construction period.

[0005] The technical problem to be solved by the utility model can be achieved through the following technical scheme: a cavity device for constructing a wall in an assembled structure, comprising a wall, vertical steel bars, transverse steel bars, hollow pipes and steel bar connectors, wherein a plurality of the hollow pipes, vertical steel bars and transverse steel bars are provided, and the vertical steel bars are equidistantly arranged laterally on the outside of the wall, the transverse steel bars are equidistantly arranged vertically on the outside of the wall, the steel bar connectors are fixedly arranged at the intersection of the vertical steel bars and the transverse steel bars, the hollow pipes are equidistantly arranged on the inside of the wall, and the inside of the wall is provided with pipe fixings for fixing the hollow pipes.

[0006] As a further solution of the utility model: the pipe fixing part includes a first clamping plate, a second clamping plate, a bolt and a nut, the first clamping plate and the second clamping plate are symmetrically provided with a limiting groove for clamping the hollow pipe and a fixing groove for clamping the vertical steel bars, the first clamping plate and the second clamping plate are also provided with a through hole, the bolt is penetrated through the through hole, and the nut is connected with the bolt in cooperation.

[0007] As a further solution of the utility model: the limiting groove and the fixing groove are further provided with slots which are staggered and distributed with each other.

[0008] As a further solution of the utility model: the hollow tube is made of PVC material.

[0009] As a further solution of the utility model: both ends of the hollow tube are equipped with sealing end covers.

[0010] As a further solution of the utility model: the steel bar connector is a connecting wire.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By setting hollow pipes in the wall and forming multiple cavities, the overall weight of the wall is greatly reduced. This not only reduces the difficulty of hoisting and transportation costs during construction, but also improves installation efficiency and shortens the construction period.

[0013] 2. The staggered slots enable the pipe fixture to adapt to the hollow pipes of different diameters or sizes by adjusting the spacing between the first clamping plate and the second clamping plate. This highly adaptable feature enables the cavity device to be applied to a wider range of prefabricated buildings to meet different building needs.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 4 As shown, a cavity device for constructing a wall in an assembled structure includes a wall 1, vertical steel bars 2, transverse steel bars 3, hollow pipes 5 and steel bar connectors 4. A plurality of hollow pipes 5, vertical steel bars 2 and transverse steel bars 3 are provided, and the vertical steel bars 2 are arranged equidistantly and laterally on the outside of the wall 1, and the transverse steel bars 3 are arranged equidistantly and vertically on the outside of the wall 1. Specifically, the vertical steel bars 2 and the transverse steel bars 3 are arranged equidistantly on the outside of the wall 1 to form a grid-like skeleton structure to enhance the overall strength and stability of the wall 1. The steel bar connector 4 is fixedly arranged at the intersection of the vertical steel bars 2 and the transverse steel bars 3, and the steel bar connector 4 is used to fix these steel bars to ensure that they are firmly connected at the intersection. The hollow pipes 5 are arranged equidistantly on the inner side of the wall 1, and the inner side of the wall 1 is provided with pipe fixings 7 for fixing the hollow pipes 5. The hollow pipes 5 are arranged equidistantly on the inner side of the wall 1 and are fixed by the pipe fixings 7. These hollow pipes 5 not only reduce the overall weight of the wall 1 , but also form a plurality of cavities in the wall 1 , which helps to improve the thermal insulation and sound insulation performance of the wall 1 .

[0024] Specifically, first, vertical steel bars 2 and transverse steel bars 3 are arranged equidistantly on the outside of the wall 1, and these steel bars are arranged perpendicularly and staggered to form a grid-like skeleton structure. This structure not only enhances the overall strength and stability of the wall 1, but also provides a solid foundation for subsequent fixing and pouring.

[0025] At the intersection of the vertical steel bars 2 and the transverse steel bars 3, steel bar connectors 4 are used for fixing to ensure that the steel bars are firmly connected at the intersection to form a stable overall structure.

[0026] Next, hollow pipes 5 are arranged at equal intervals on the inner side of the wall 1, and these hollow pipes 5 are connected and fixed to the corresponding vertical steel bars 2 through pipe fixing members 7. These hollow pipes 5 form multiple cavities in the wall 1, while reducing the overall weight of the wall 1.

[0027] After completing the above steps, the transverse reinforcement 3, the vertical reinforcement 2 and the hollow pipe 5 are cast to make them tightly combined together to form a complete wall 1. The casting material can be concrete or other suitable materials to ensure the firmness and durability of the wall 1.

[0028] By arranging the hollow pipe 5 in the wall 1 and forming a plurality of cavities, the overall weight of the wall 1 is greatly reduced. This not only reduces the difficulty of hoisting and transportation costs during the construction process, but also improves the installation efficiency and shortens the construction period.

[0029] The use of the grid-like skeleton structure and the steel bar connector 4 makes the wall 1 more stable and strong in structure. The addition of the hollow pipe 5 also improves the compression resistance and durability of the wall 1, and can effectively disperse and withstand external forces, thereby improving the overall stability of the wall 1.

[0030] The cavity device adopts a prefabricated structure, which can be prefabricated and assembled in the factory and then transported to the site for installation. This construction method simplifies the on-site operation process, improves construction efficiency and reduces construction costs.

[0031] By adjusting the arrangement density and size of the vertical steel bars 2, the transverse steel bars 3 and the hollow tubes 5, the thickness, strength and thermal insulation and sound insulation parameters of the wall 1 can be flexibly adjusted to meet the needs of different construction projects.

[0032] refer to Figure 3 and Figure 4 As shown, in some specific embodiments, the pipe fixing member 7 includes a first clamping plate 71, a second clamping plate 72, a bolt 73 and a nut 74. The first clamping plate 71 and the second clamping plate 72 are symmetrically provided with a limit groove 75 for clamping the hollow pipe 5 and a fixing groove 76 for clamping the vertical steel bar 2, so that the hollow pipe 5 and the vertical steel bar 2 can be firmly clamped between the first clamping plate 71 and the second clamping plate 72 at the same time. The first clamping plate 71 and the second clamping plate 72 are also provided with a through hole 77, and the bolt 73 is arranged in the through hole 77, and the nut 74 is connected with the bolt 73. This bolt 73 connection method is not only simple and easy, but also can effectively connect the two clamping plates tightly together, thereby ensuring the firm fixation of the hollow pipe 5 and the vertical steel bar 2.

[0033] refer to Figure 3As shown, in some specific embodiments, the limiting groove 75 and the fixing groove 76 are further provided with mutually staggered slots 78. The mutually staggered slots 78 enable the pipe fixing member 7 to adapt to the hollow pipes 5 of different diameters or sizes by adjusting the spacing between the first clamping plate 71 and the second clamping plate 72. This highly adaptable feature enables the cavity device to be applied to a wider range of prefabricated buildings to meet different building requirements.

[0034] In some specific embodiments, the hollow tube 5 is made of PVC material. PVC material has a low density, so the hollow tube 5 made is relatively light, which helps to reduce the overall weight of the wall 1. At the same time, PVC material also shows high strength and rigidity, can withstand certain external forces, and ensure the stability and safety of the wall 1. At the same time, PVC material has good corrosion resistance and can resist corrosion from a variety of chemical substances, including acids, alkalis, salts, etc. This allows the PVC hollow tube 5 to maintain stable performance even in a humid or corrosive environment, extending the service life of the wall 1.

[0035] refer to Figure 1 and Figure 2 As shown, in some specific embodiments, both ends of the hollow tube 5 are equipped with sealing end caps 6. The sealing end caps 6 are used to ensure the sealing of both ends of the hollow tube 5, thereby ensuring the safety and stability of the hollow tube 5 during use.

[0036] refer to Figure 1 and Figure 2 As shown, in some specific embodiments, the steel bar connector 4 is a connecting wire. When the steel bar connector 4 is a connecting wire, this connection method is generally called a binding connection. The binding connection is to tightly bind the vertical steel bars 2 and the transverse steel bars 3 together with the connecting wire to achieve the purpose of connection and fixation. During the binding process, the wire needs to pass through the intersection of the vertical steel bars 2 and the transverse steel bars 3, and is wound and tightened multiple times to ensure a firm connection between the steel bars.

[0037] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0038] In the factory or on-site prefabrication area, the vertical steel bars 2 and the transverse steel bars 3 are arranged in an equidistant and staggered manner to form a grid-like skeleton structure. The intersections of the vertical steel bars 2 and the transverse steel bars 3 are tied firmly using steel bar connectors 4 to form a stable overall structure. Subsequently, the hollow pipes 5 are equidistantly arranged at preset positions and connected and fixed to the vertical steel bars 2 using pipe fixtures 7.

[0039] Next, the transverse reinforcement 3, the vertical reinforcement 2 and the hollow pipe 5 are cast to make them tightly combined together to form a complete wall 1. The casting material can be concrete or other suitable materials to ensure the firmness and durability of the wall 1.

[0040] By arranging the hollow pipe 5 in the wall 1 and forming a plurality of cavities, the overall weight of the wall 1 is greatly reduced. This not only reduces the difficulty of hoisting and transportation costs during the construction process, but also improves the installation efficiency and shortens the construction period.

[0041] The use of the grid-like skeleton structure and the steel bar connector 4 makes the wall 1 more stable and strong in structure. The addition of the hollow pipe 5 also improves the compression resistance and durability of the wall 1, and can effectively disperse and withstand external forces, thereby improving the overall stability of the wall 1.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
