Description

Technical Field

[0001] This utility model relates to the field of building decoration materials technology, specifically to a crack-resistant splicing structure for lightweight partition boards. Background Technology

[0002] Lightweight partition walls are commonly used non-load-bearing partition wall materials in construction projects. They are characterized by their light weight, convenient construction, fire resistance, and moisture resistance, and are widely used in partition projects for residential, commercial spaces, and industrial plants. Their splicing structure, as the core component connecting multiple wall panels to form a complete wall surface, primarily functions to achieve interlocking between panels through mechanical interlocking and adhesive bonding, ensuring the integrity and stability of the wall surface.

[0003] In existing technologies, lightweight partition wall panels often employ a simple tenon-and-groove joint structure. However, this method presents several problems in practical applications: First, the rigid contact between the traditional tenon and groove joint is prone to stress concentration due to temperature deformation, humidity changes, or external impacts, leading to cracking at the joints. Second, the joints lack effective sliding buffer designs, preventing the absorption of minor displacements caused by the panel's weight or environmental factors, thus exacerbating stress accumulation at the interface. Third, the positioning reliability of the joint structure is insufficient; the groove joint can easily detach from the tenon due to loosening of the interlocking tenon, affecting the overall safety of the wall surface. These problems directly shorten the service life of the lightweight partition wall panel joints and increase subsequent maintenance costs. Utility Model Content

[0004] The purpose of this invention is to address the problems of insufficient crack resistance and poor connection stability in existing lightweight partition wall panel splicing structures, and to provide a crack-resistant splicing structure with elastic buffering, dynamic positioning and efficient bonding functions. By optimizing the male and female tenon mating method and adding auxiliary buffer components, the stress concentration resistance and long-term reliability of the splicing interface are improved.

[0005] The technical solution provided by this utility model is a crack-resistant splicing structure for lightweight partition boards, including a first wall panel and a second wall panel. The upper end of the splicing end face of the first wall panel is provided with a protruding male tenon, and the upper end of the splicing end face of the second wall panel is provided with a grooved female tenon that matches the male tenon. At the same time, the lower end of the splicing end face of the first wall panel is provided with the same female tenon as the second wall panel, and the lower end of the splicing end face of the second wall panel is provided with the same male tenon as the first wall panel. The front end of the male tenon is slidably connected to a plug-in tenon through a guide groove, and the lower part of the inner side of the female tenon is provided with a positioning groove that matches the shape of the plug-in tenon. The two vertical surfaces of the male tenon are fitted with an elastic crack-resistant layer, which protrudes 0.5-2mm from the surface of the male tenon. The female tenon is provided with a limiting insertion hole that matches the positioning groove above the positioning groove, and a positioning pin is inserted through the limiting insertion hole.

[0006] As a preferred technical solution of this utility model, the guide groove is a dovetail groove, the plug-in tenon is provided with a corresponding dovetail tenon at the guide groove, and the bottom of the plug-in tenon is not provided with a dovetail tenon at the positioning groove.

[0007] As a preferred technical solution of this utility model, the plug-in tenon is provided with an auxiliary hole at the limiting insertion hole to help slide up and down, and the top of the plug-in tenon is provided with a recessed lifting ring to assist in lifting the plug-in tenon during disassembly.

[0008] As a preferred technical solution of this utility model, the elastic anti-crack layer is a closed-cell foam rubber strip or a silicone sealing strip, the cross-section of which is T-shaped and is embedded in the side of the tenon through a dovetail groove.

[0009] As a preferred technical solution of this utility model, the groove of the female tenon is provided with chamfered bevels on both sides, the chamfer angle is 30°-45°, and the chamfer depth matches the protrusion height of the elastic anti-crack layer.

[0010] As a preferred embodiment of this utility model, the limiting insertion hole penetrates the tenon on the first wall panel and the second wall panel, and the positioning pin matches the size of the limiting insertion hole.

[0011] As a preferred technical solution of this utility model, the positioning pin is composed of a T-shaped insertion end and a plate-shaped limiting plate, and the two are fixedly connected by bolts. The first wall plate and the second wall plate are provided with fixing grooves at the limiting insertion hole that match the shape of the insertion end and the limiting plate.

[0012] As a preferred technical solution of this utility model, the bottom of the female tenon is provided with a longitudinal guide groove, and the top of the longitudinal guide groove is connected to one side of the first wall panel and the second wall panel to form an adhesive injection channel. The angle between the adhesive injection channel and the wall surface is 45°-60°.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. Improved crack resistance: The elastic anti-crack layer (closed-cell foam rubber or silicone) embedded on both sides of the tenon can effectively buffer the stress caused by temperature and humidity changes between the boards. The design of protruding 0.5-2mm from the surface of the tenon ensures the elastic deformation space when in contact, while avoiding excessive protrusion that affects the splicing accuracy.

[0015] 2. Reliable dynamic positioning: The male tenon is slidably connected to the interlocking tenon through the guide groove of the dovetail groove-dovetail tenon structure. After the bottom of the interlocking tenon is inserted into the positioning groove of the female tenon, it achieves vertical locking. With the T-shaped positioning pin passing through the limiting insertion hole and fitting into the wall panel fixing groove, it can effectively prevent the female tenon from coming out of the male tenon due to vibration or external force, and improve the shear strength of the splicing node.

[0016] 3. Convenient assembly and maintenance: The 30°-45° chamfered bevel of the female tenon groove guides the male tenon to be inserted smoothly, and the lifting ring at the top of the interlocking tenon provides a force point for disassembly, making lifting easier; the longitudinal guide groove and 45°-60° adhesive injection channel design allow the adhesive to penetrate evenly to the splicing interface under the action of gravity, enhancing the reliability of bonding.

[0017] 4. Strong structural adaptability: The symmetrical male and female tenon interlocking structure can adapt to splicing requirements in different directions. The T-shaped cross section and dovetail groove embedding method of the elastic crack-resistant layer take into account both buffer performance and installation stability, and are suitable for connecting lightweight partition boards of various specifications.

[0037] Working principle

[0038] 1. Assembly process: Align the upper male tenon 3 of the first wall panel 1 with the upper female tenon 4 of the second wall panel 2, and use the chamfered bevel 14 of the groove of the female tenon 4 to guide the male tenon 3 to be inserted; at the same time, align the lower female tenon 4 of the first wall panel 1 with the lower male tenon 3 of the second wall panel 2 to complete the symmetrical assembly.

[0039] 2. Locking and positioning: Push the insertion tenon 6 to slide along the direction of the female tenon 4 until the bottom of the insertion tenon 6 is engaged in the positioning groove 7 of the female tenon 4, and make the insertion tenon 6 inserted into the positioning groove 7 below to achieve vertical locking; insert the T-shaped insertion end 15 of the positioning pin 10 into the limiting insertion hole 9, and fix the limiting plate 16 to the wall panel with the bolt 17 to limit the longitudinal displacement of the insertion tenon 6, and limit the lateral displacement of the male tenon 3 by the insertion tenon 6 to prevent it from coming out.

[0040] 3. Stress buffering: When the wall panel expands or contracts due to changes in temperature or humidity, the elastic anti-crack layer 8 on both sides of the tenon 3 undergoes elastic deformation to absorb the stress at the splicing interface and prevent cracking.

[0041] 4. Adhesive reinforcement: During construction, adhesive is injected into the longitudinal guide groove 19 through the adhesive injection channel 20. The adhesive is evenly filled into the gap between the male tenon 3 and the female tenon 4 along a 45° angle path. After curing, it works together with the elastic anti-crack layer 8 to improve the bonding strength and shear resistance of the splicing joint.

[0042] 5. Disassembly and maintenance: When disassembly is required, loosen the fixing bolt 17 of the positioning pin 10, and lift it upward through the lifting ring 13 and auxiliary hole 12 at the top of the insertion tenon 6 to disengage the insertion tenon 6 from the positioning groove 7. Then, the insertion tenon 6 can be pulled out along the guide slide 5 to complete the separation of the spliced ​​structure.

[0043] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
