Description

Technical Field

[0001] This utility model relates to the field of precast concrete assembled houses, specifically a vertical connection structure for the structural nodes of a precast concrete assembled house module wall. Background Technology

[0002] Precast concrete is poured elsewhere, not on the final construction site. Precast concrete of various sizes and shapes can be reinforced with fibers to enhance its reliability and resilience after cracking. In recent years, precast concrete has become a favorite in the construction industry due to its low cost and excellent performance. Its wide variety of styles and weights, coupled with excellent flexural strength and performance, have led to its widespread application in road barriers, water storage tanks, exterior walls, building construction, and decoration. Precast concrete can accelerate the industrialization of housing, which is one of the key areas of my country's economic system reform. For example, the authorized patent with publication number CN217379409U (Reinforced Concrete Composite Wall) includes: a first precast wall panel including multiple first fixing structures; a second precast wall panel including multiple second fixing structures; multiple first fixing cages, each including multiple first fixing rings and disposed between the first and second precast wall panels; multiple first fixing rods; multiple second fixing rods, parallel to the first fixing rods and extending along a first direction; and concrete poured between the first and second precast wall panels. These first fixing rings overlap with the first and second fixing structures respectively, allowing the first and second fixing rods to pass through the overlapping area. This reinforced concrete composite wall has a stable connection structure, giving the composite wall high load-bearing capacity. The existing wall technology mentioned above lacks precision in the vertical connection process, cannot adjust the distance between the stirrups of the two assemblies according to the assembly requirements, lacks versatility, and is relatively troublesome to assemble on site, making it inconvenient to complete the interlocking installation on site. The connection of a single straight rebar is not stable enough. Utility Model Content

[0003] The purpose of this utility model is to provide a vertical connection structure for the modular wall structure of a precast concrete assembly house, so as to solve the problems mentioned in the background art, such as insufficient accuracy of the vertical connection process of the wall, inability to adjust the distance of the stirrups between the two assemblies according to the assembly requirements, insufficient versatility, and the fact that on-site assembly is relatively troublesome, inconvenient to complete the interlocking installation on-site, and the instability of single straight steel bar connection.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vertical connection structure for a precast concrete modular wall structure, comprising a first vertical steel reinforcement group, a first concrete wall, a first stirrup, a second concrete wall, a second stirrup, a third concrete wall, a fourth concrete wall, and a second vertical steel reinforcement group. The first concrete wall and the third concrete wall, as well as the second concrete wall and the fourth concrete wall, are connected by interlocking holes formed by the outer ends of the first stirrup and the second stirrup on their inner sides. The interlocking holes are formed by the interlocking holes formed by the first vertical steel reinforcement group and the second vertical steel reinforcement group arranged vertically, and the components are bound together with tie wire.

[0005] In a further embodiment, the inner walls of the first concrete wall, the second concrete wall, the third concrete wall and the fourth concrete wall are all provided with reinforcing bars. The reinforcing bars are tied to the first stirrup and the second stirrup, and the reinforcing bars are bent into a horizontal U-shaped structure, with their two ends extending into the floor slab mold cavity and the floor slab mold cavity, respectively.

[0006] In a further embodiment, both the first vertical steel bar group and the second vertical steel bar group are configured as trapezoidal structures. The bottom of the first vertical steel bar group is configured as a curved structure, and the top steel bar of the second vertical steel bar group extends out, so that the end of the first vertical steel bar group and the top of the second vertical steel bar group are arranged side by side and attached.

[0007] In a further embodiment, both the first stirrup and the second stirrup are square structures, and multiple sets of both the first stirrup and the second stirrup are provided. The distance between the first stirrup and the second stirrup assembled together can be adjusted.

[0008] In a further embodiment, the first, second, third, and fourth concrete walls are each provided with a top plate and a bottom plate at both ends, and the bottom plate of the first concrete wall is connected to the top plate of the second concrete wall, and the bottom plate of the third concrete wall is connected to the top plate of the fourth concrete wall.

[0009] In a further embodiment, the joints between the first concrete wall, the second concrete wall, the third concrete wall and the fourth concrete wall are provided with pre-casting areas, and the sealing connection is strengthened by a sealing structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. The first, third, second, and fourth concrete walls of this utility model are assembled using multiple sets of superimposed first and second stirrups, which makes the assembly more stable. The walls can be vertically assembled using the first and second vertical steel reinforcement groups. The extended end of the second vertical steel reinforcement is inserted into the first and third concrete walls and can be connected and sealed with concrete. Force is transmitted through the first and second vertical steel reinforcement groups, which facilitates the connection.

[0011] 2. During the splicing process, the first and second stirrups of this utility model can be adjusted to offset each other, which can improve the flexibility of wall assembly and effectively improve the versatility of wall assembly. Both the first and second vertical steel bar groups are designed as trapezoidal structures, which make the wall assembly more stable compared to straight steel bars. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figure 1-8 This utility model provides an embodiment of a vertical connection structure for a precast concrete modular wall structure, comprising a first vertical steel reinforcement group 1, a first concrete wall 3, a first stirrup 4, a second concrete wall 5, a second stirrup 6, a third concrete wall 7, a fourth concrete wall 8, and a second vertical steel reinforcement group 9. The first concrete wall 3, the third concrete wall 7, the second concrete wall 5, and the fourth concrete wall 8 are all connected by staggered interlocking of the outer ends of the first stirrup 4 and the second stirrup 6 on their inner sides to form interlocking holes. The multiple vertically assembled first stirrup 4 and second stirrup 6 are interlocked and installed by the staggered interlocking of the first vertical steel reinforcement group 1 and the second vertical steel reinforcement group 9, and are bound together by tie wire.
