Description

Technical Field

[0001] This utility model relates to the field of prefabricated wall technology, and more specifically, it relates to a connection structure between prefabricated wall modules. Background Technology

[0002] In recent years, prefabricated building technology has been widely used in the construction industry due to its high construction efficiency and good environmental performance. As a core component, the modular installation quality of prefabricated walls directly affects the precision and safety of the overall building structure.

[0003] However, in actual construction, it was found that traditional precast wall panels have significant installation positioning defects when splicing adjacent panels. In existing technology, precast wall panels usually adopt a flat edge design. However, since the two adjacent precast wall panels are relatively independent, if the adjacent precast wall panels are misaligned after being hoisted into place, and because the precast wall panels are heavy, it is difficult to manually fine-tune and align them, which affects the final overall installation quality.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a connection structure between prefabricated wall modules.

[0006] The technical solution of this utility model is:

[0007] A connection structure between prefabricated wall modules includes a plurality of prefabricated wall modules arranged in an array. Adjacent prefabricated wall modules are arranged in an array along the vertical direction with a plurality of connecting components for limiting the two modules to move away from each other in the planar direction. Each of the prefabricated wall modules is provided with a fixed long beam at the top and bottom. The length of the fixed long beam is equal to the sum of the widths of the prefabricated wall modules. The fixed long beam and the prefabricated wall modules are fixedly connected by screws.

[0008] The present invention is further configured such that the connecting component includes a male fastener and a female fastener that cooperate with each other. The male fastener and the female fastener are respectively fixedly connected to the opposite side of adjacent precast wall modules by screws. A positioning male end is fixedly connected to the side of the male fastener facing the female fastener. The female fastener has a positioning port that cooperates with the positioning male end. The positioning male end includes an extension and a limiting part. The limiting part is located at the end of the extension that is away from the male fastener and has a diameter larger than the extension. The positioning port includes a placement part and a mating part. The width of the placement part is larger than the diameter of the limiting part, and the width of the mating part is equal to the diameter of the extension.

[0009] The present invention is further configured such that, on the side of the female fastener away from the male fastener, there are mutually symmetrically arranged limiting members between the placement part and the mating part, the limiting members are rotatably connected to one side of the female fastener, the limiting members extend in a direction that approaches each other, and the minimum distance between two adjacent limiting members is less than the diameter of the extension part.

[0010] The present invention is further provided that a torsion spring is provided between the limiting member and the female fastener, and the torsion spring has elastic deformation potential energy that causes the two limiting members to rotate toward each other.

[0011] The present invention is further configured such that the connecting component includes a connector, and two adjacent precast wall modules have interconnected notches on their sides that are close to each other. The connector is embedded in the notch. The connector has an annular cross-section. The connector has symmetrically arranged circular holes for bolts to pass through on its side away from the notch. The connector has symmetrically arranged strip holes for bolts to pass through on its side facing the notch. An isolation member is integrally formed in the middle of the connector.

[0012] The present invention is further configured such that the connecting component includes two U-shaped steels, the two U-shaped steels are respectively fixed to the opposite side of two adjacent precast wall modules by screws, the length of the U-shaped steels is equal to the length of the precast wall modules, the U-shaped steels are provided with interpenetrating waist-shaped holes, and the two adjacent U-shaped steels are centrally symmetrically arranged and fixedly connected by bolts passing through the waist-shaped holes.

[0013] The beneficial technical effects of this utility model are:

[0014] By employing connecting components, the distance between adjacent precast wall modules can be limited, allowing for the pre-installation of adjacent precast wall modules and preventing misalignment caused by mutual offset. This ensures installation quality. After the pre-installation of all precast wall modules is completed, fixed beams are used to secure all precast wall modules, completing the installation of the entire wall. This results in a neater wall installation, maximizing time and labor cost savings while ensuring safety and stability. Attached Figure Description

[0023] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] Example 1,

[0025] A connection structure between prefabricated wall modules, such as Figure 1 and Figure 2 As shown, the system includes several prefabricated wall modules 1 arranged in an array. Adjacent prefabricated wall modules 1 are vertically arranged with several connecting components to restrict them from moving away from each other in the planar direction. Each prefabricated wall module 1 has a fixed long beam 7 at its top and bottom. The length of the fixed long beam 7 is equal to the sum of the widths of the prefabricated wall modules 1. The fixed long beam 7 and the prefabricated wall modules 1 are fixedly connected by screws. By setting the connecting components, adjacent prefabricated wall modules 1, after being hoisted to their respective positions, can be fixed together, restricting them from moving away from each other, thereby preventing misalignment of adjacent prefabricated wall modules 1. The fixed long beam 7 provides reinforcement, ensuring the installation effect.

[0026] The connecting assembly includes a male fastener 2 and a female fastener 3 that cooperate with each other. The male fastener 2 and the female fastener 3 are respectively fixedly connected to the opposite side of adjacent precast wall modules 1 by screws. A positioning male end 21 is fixedly connected to the side of the male fastener 2 facing the female fastener 3. The female fastener 3 has a positioning port 31 that cooperates with the positioning male end 21. The positioning male end 21 includes an extension 211 and a limiting part 212. The limiting part 212 is located at the end of the extension 211 away from the male fastener 2 and has a diameter larger than the extension 211. The positioning port 31 includes a placement part 311 and a mating part. 312, the width of the placement part 311 is greater than the diameter of the limiting part 212, and the width of the mating part 312 is equal to the diameter of the extension part 211. A clearance groove for the positioning male end 21 to pass through is provided on the side of the precast wall module 1 with the female fastener 3. After the positioning male end 21 is inserted into the positioning port 31 by the male fastener 2 and the female fastener 3, the mating part 312 at the positioning port 31 is used to limit the distance between two adjacent precast wall modules 1 and their relative positioning, thereby preventing the phenomenon of skew.

[0027] On the side of the female fastener 3 facing away from the male fastener 2, symmetrically arranged between the placement part 311 and the mating part 312 are limiting members 4. The limiting members 4 can extend into the relief groove. The limiting members 4 are rotatably connected to one side of the female fastener 3. The limiting members 4 extend in the direction of mutual approach, and the minimum distance between two adjacent limiting members 4 is less than the diameter of the extension part 211. A torsion spring is provided between the limiting members 4 and the female fastener 3. The torsion spring has elastic deformation potential energy that causes the two limiting members 4 to rotate in the direction of mutual approach. By setting the limiting members 4, after the extension part 211 extends into the mating part 312, the limiting members 4 can be reset under the action of the torsion spring, which can prevent the positioning male end 21 from re-entering the placement part 311 and disengaging from the positioning port 31 of the placement part 311.

[0028] Working principle: First, one precast wall module 1 is hoisted to the corresponding position. Then, another precast wall module 1 is hoisted to one side. The operator fine-tunes the precast wall module 1 so that the positioning male end 21 aligns with the placement part 311 of the positioning port 31. The two precast wall modules 1 are brought closer together so that the positioning male end 21 passes through the placement part 311 and extends into the clearance groove. The crane is lowered, and the limiting part 212 first contacts the limiting member 4. Due to gravity, the limiting member 4 rotates in a direction away from each other. The torsion spring is deformed by external force until the extension part 21 of the positioning male end 21... 11 extends fully into the mating part 312 and the limiting part 212 moves away from the limiting part 212. The torsion spring resets, driving the limiting member 4 to reset, so that the limiting members 4 move closer to each other, thereby preventing the positioning male end 21 from re-entering the placement part 311 and disengaging from the positioning port 31. The pre-installation of two adjacent prefabricated wall modules 1 is completed to prevent misalignment caused by mutual offset, ensuring the installation quality. After the pre-installation between all prefabricated wall modules 1 is completed, the fixed long beam 7 is used to fix all prefabricated wall modules 1 to complete the installation of the entire wall.

[0029] Example 2 differs from Example 1 in that:

[0030] like Figure 3 , Figure 4 and Figure 5 As shown, the connecting component includes a connector 5. Two adjacent precast wall modules 1 have interconnected notches on their sides, into which the connector 5 is embedded. The connector 5 has an annular cross-section. On the side of the connector 5 away from the notch, there are symmetrically arranged circular holes 51 for screws to pass through. On the side of the connector 5 facing the notch, there are symmetrically arranged strip holes 52 for screws to pass through. Since the precast wall module 1 is a wooden wall, screws are driven into the wall through the circular holes 51 and then through the strip holes 52, thus fixing the connector 5 to the precast wall module 1. The strip holes 52 allow for fine-tuning after the screws pass through, achieving the effect of fine-tuning the precast wall module 1 and ensuring the leveling of adjacent precast wall modules 1. The connector 5 completes the pre-installation between adjacent precast wall modules 1. An integrally formed separator 53 in the middle of the connector 5 isolates two screws on the same connector 5, making installation more convenient.

[0031] Example 3 differs from Example 1 in that:

[0032] like Figure 6 and Figure 7As shown, the connecting assembly includes two U-shaped steels 6. The two U-shaped steels 6 are respectively fixed to the opposite side of two adjacent precast wall modules 1 by screws. The length of the U-shaped steel 6 is equal to the length of the precast wall module 1. The U-shaped steel 6 has through holes 61. The two adjacent U-shaped steels 6 are centrally symmetrical and fixedly connected by bolts passing through the holes 61. Using the U-shaped steels 6, the U-shaped steels 6 of the two adjacent precast wall modules 1 are interlocked to form two U-shaped steels 6 that are centrally symmetrical and whose holes 61 are interconnected. Because the holes 61 are waist-shaped, the connecting space between the two holes 61 is relatively large, allowing for fine-tuning of the two precast wall modules 1. Then, bolts are used to pass through and hexagonal nuts are used for reinforcement to complete the fixation of the two U-shaped steels 6, thereby completing the pre-installation of the two adjacent precast wall modules 1.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
