Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a modular building wall form. Background Art

[0002] Modular integrated construction involves breaking down individual buildings into modules based on spatial structure, apartment layout, and functional zoning. These modules are then prefabricated in a factory and transported to the construction site for installation. The resulting building entity meets safety, reliability, and relevant functional requirements. Compared to traditional construction methods, modular integrated construction offers advantages such as high efficiency, energy conservation, and environmental friendliness.

[0003] Chinese patent CN218933525U discloses a modular building wall formwork that requires no disassembly. The formwork includes a first formwork and a second formwork, with truss bars installed on the first formwork. This modular wall formwork does not integrate the shear wall reinforcement. Therefore, after the modules are installed at the construction site and before pouring the shear wall concrete, the shear wall reinforcement is tied on-site. However, the presence of the truss bars makes on-site reinforcement tying difficult.

[0004] Therefore, there is an urgent need for a wall formwork that can gather the shear wall stress reinforcement. Utility Model Content

DETAILED DESCRIPTION

[0037] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below with reference to the accompanying drawings and through specific implementation methods. Figure 2 For reference, the axial direction of the first steel bar 6 is defined as the "vertical direction", the axial direction of the tensioning device 8 is defined as the "left-right direction", and the axial direction of the second steel bar 5 is defined as the "front-back direction".

[0038] Example 1

[0039] like Figures 1 to 4 As shown, a modular building wall formwork is shown. In this embodiment, the cross-section of the modular building wall formwork is rectangular, meaning that the modular building wall formwork has no corners. The modular building wall formwork comprises a first formwork 1 and a second formwork 2, arranged in parallel and spaced relation, and a reinforcement cage. Installed between the first and second formworks 1 and 2, the reinforcement cage extends parallel to the first formwork 1, with one side connected to the first formwork 1 and the other to the second formwork 2. The reinforcement cage includes two vertically extending edge members, each mounted at either end of a second reinforcement 5. Both edge members are connected to a plurality of second reinforcements 5.

[0040] The utility model increases the integration of the modular building wall formwork by installing the steel cage between the first formwork 1 and the second formwork 2. When the modular building wall formwork is used to assemble house construction, there is no need to tie the steel cage on site, which solves the problem of difficult on-site tying of the steel cage, reduces on-site construction procedures, speeds up construction progress, and improves construction efficiency.

[0041] The first formwork 1 and the second formwork 2 may be configured such that one is a wall formwork for concrete pouring 3 and the other is a metal formwork, such as an aluminum formwork or a steel formwork. Alternatively, both the first formwork 1 and the second formwork 2 may be wall forms for concrete pouring. In this embodiment, the example of both the first formwork 1 and the second formwork 2 being wall forms for concrete pouring is used.

[0042] In this embodiment, one of the first and second formworks 1 and 2 serves as an exterior wall, and the other serves as an interior wall. If one of the first and second formworks 1 and 2 is a metal formwork, the metal formwork serves as the exterior wall. If both the first and second formworks 1 and 2 are concrete wall forms, either one can serve as the exterior wall. Insulation, exterior wall decoration, wooden wall panels, etc. can be installed on the exterior side of the exterior wall (the side of the exterior wall away from the steel cage is defined as the exterior side). These insulation, exterior wall decoration, wooden wall panels, etc. can be prefabricated directly on the exterior side of the exterior wall as needed, eliminating the need for on-site processing or decoration of the exterior wall during construction. This reduces on-site construction workload and increases production speed. Both the first and second formworks 1 and 2 are prefabricated modules constructed from steel bars and concrete. Specifically, both the first and second formworks 1 and 2 are constructed using ECC (fiber cement composite) concrete with a thickness of 15 mm to 30 mm. Due to the high strength and toughness of ECC concrete, wall forms of the same thickness are stronger than those constructed from conventional concrete. That is to say, in this application, the wall formwork cast using ECC concrete has a smaller thickness than the wall formwork cast using ordinary concrete while maintaining the same strength.

[0043] like Figure 2As shown, the edge member further includes a plurality of third steel bars 112 arranged in a vertical direction and a plurality of stirrups 111 arranged in a horizontal direction. The plurality of third steel bars 112 are arranged in a rectangular parallelepiped shape. The plurality of stirrups 111 are spaced apart and sleeved on the plurality of third steel bars 112 arranged in the rectangular parallelepiped shape. The stirrups 111 are rectangular rings and are welded to the plurality of third steel bars 112. Specifically, the plurality of third steel bars 112 are divided into two columns of third steel bars, and the two columns of third steel bars are arranged in a one-to-one correspondence with the two columns of first steel bars.

[0044] like Figures 1 to 3 As shown, the steel cage includes a plurality of first steel bars 6 spaced apart in a vertical direction, a plurality of tie bars 12, and a plurality of second steel bars 5 spaced apart and arranged parallel to the first formwork 1. The plurality of first steel bars 6 are arranged in two parallel and spaced rows, and the plurality of second steel bars 5 are arranged in two parallel and spaced rows. The two second steel bar rows are installed on opposite sides of the two first steel bar rows. Each second steel bar row includes a plurality of second steel bars 5 spaced apart in a vertical direction. The first steel bars 6 are connected to the second steel bars 5. The first steel bars 6, the second steel bars 5, and the edge members are all connected to the tie bars 12. The plurality of tie bars 12 are arranged in multiple layers in a vertical direction, each layer including multiple tie bars 12. Specifically, the tie bars 12 are arranged in a left-right direction and are welded to the first steel bars 6, the second steel bars 5, and the edge members. One end of the tie bar 12 is connected to the first formwork 1, and the other end is connected to the second formwork 2.

[0045] The tie rod 12 can be a first connecting rod of a straight structure, and the two ends of the first connecting rod are respectively embedded in the first template 1 and the second template 2. It can also be, for example Figure 6 As shown, the tie rod 12 includes two parallel second connecting rods 121 spaced apart in an upper and lower arrangement. A U-shaped connecting frame 122 is perpendicularly connected to the same end of the two second connecting rods 121. The U-shaped connecting frame 122 is arranged parallel to the first template 1. In this embodiment, there are two U-shaped connecting frames 122, which are respectively mounted at both ends of the first connecting rod and embedded in the first template 1 and the second template 2.

[0046] like Figures 1 to 3 As shown, when the tie bar 12 is the first connecting rod, multiple pre-embedded anchor bars 7 extending in the vertical direction are installed in both the first formwork 1 and the second formwork 2. The multiple pre-embedded anchor bars 7 are arranged at intervals in the front-to-back direction, and the multiple pre-embedded anchor bars 7 are arranged one-to-one with the multiple tie bars 12 in each tie bar layer. One end of the tie bar 12 is connected to the pre-embedded anchor bar 7 in the first formwork 1, and the other end of the tie bar 12 is connected to the pre-embedded anchor bar 7 in the second formwork 2.

[0047] When the tie rod 12 includes two second connecting rods 121 and a U-shaped connecting frame 122, the embedded anchor bar 7 is not installed in the template where the U-shaped connecting frame 122 is located, and the embedded anchor bar 7 is provided in the other template, and the second connecting rod 121 is connected to the corresponding embedded anchor bar 7.

[0048] Example 2

[0049] Unlike Example 1, in this embodiment, one of the first formwork 1 and the second formwork 2 is a concrete wall formwork, and the other is a metal formwork, wherein the metal formwork can be an aluminum formwork or a steel formwork. Furthermore, in this embodiment, the first formwork 1 is a concrete wall formwork, and the second formwork 2 is a metal formwork.

[0050] The modular building wall formwork also includes multiple tensioning devices 8, which are used to connect the first formwork 1 and the second formwork 2. The tensioning devices 8 are arranged perpendicular to the extension direction of the first formwork 1. One end of the tensioning device 8 is connected to the first formwork 1, and the other end is connected to the second formwork 2. The tensioning devices 8 are connected to the steel cage. Specifically, the steel cage is used to resist shear forces and increase the integration of the modular building wall formwork. The axial direction of the tensioning device 8 extends in the left-right direction, and the first wall 1 and the second wall 2 both extend in the front-to-back direction. One end of the tensioning device 8 is connected to the corresponding embedded anchor bar 7, and the other end of the tensioning device 8 is detachably connected to the metal formwork.

[0051] Specifically, in this embodiment, one end of the pulling device 8 is embedded in the first template 1, and the other end is detachably connected to the second template 2. Furthermore, the pulling device 8 includes a first pair of pull rods, a first nut, and a second pair of pull rods. One end of the first pair of pull rods is embedded in the first template 1, and the other end is threadedly connected to the first nut. The first nut is placed in the second template 2 away from the end of the first pair of pull rods. One end of the second pair of pull rods is fixedly connected to a connector, and the other end passes through the second template 2 and is threadedly connected to the first nut. The first pair of pull rods and the second pair of pull rods are connected by the first nut, and the connector is placed on the outside of the second template 2. The pulling device 8 connects the first template 1 and the second template 2.

[0052] like Figure 1 As shown, the embedded anchor bars 7 and the steel cage are welded to the tensioning devices 8. The plurality of tensioning devices 8 are divided into a plurality of tensioning layers spaced apart in the vertical direction; each tensioning layer includes a plurality of tensioning devices 8 spaced apart in the horizontal direction.

[0053] In this embodiment, when the tie rod 12 includes two second connecting rods and a U-shaped connecting frame, there is only one U-shaped connecting frame, and the U-shaped connecting frame is embedded in the template of the concrete wall template.

[0054] like Figure 4As shown, when using the present invention, both ends of the modular building wall formwork are connected to the concrete structural column to secure the modular building wall formwork, and then concrete is poured into the modular building wall formwork. The concrete structural column is provided with a plurality of first structural bars 9 extending vertically and a plurality of structural stirrups 10 arranged horizontally. The plurality of first structural bars 9 are arranged in a rectangular parallelepiped structure, and the plurality of structural stirrups 10 are sleeved on the plurality of first structural bars 9.
