Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and more specifically to a prefabricated modular splicing wall structure. Background Technology

[0002] In the modern construction industry, with the ever-increasing demands for construction efficiency and quality, traditional wall construction methods can no longer meet the requirements of speed, efficiency, and environmental protection. Traditional wall construction often requires a large amount of on-site wet work, such as bricklaying and plastering. These operations are not only time-consuming and labor-intensive, but also generate a large amount of construction waste, which is detrimental to environmental protection.

[0003] To address these issues, modular prefabricated wall structures have emerged. These structures utilize prefabricated wall panels that are then rapidly assembled on-site, significantly improving construction efficiency, reducing wet work, and minimizing construction waste. However, existing modular prefabricated wall structures often suffer from complex assembly processes, poor stability, and an inability to accommodate corner connections, requiring additional tools and causing inconvenience. This ultimately impacts the overall performance of the wall structure and construction efficiency.

[0004] Therefore, how to provide a modular splicing wall that is easy to disassemble and clean, convenient to maintain, energy-saving and environmentally friendly, and meets the requirements of fast, efficient and environmentally friendly construction, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a prefabricated modular splicing wall structure, which solves the problems of complex splicing and poor stability of prefabricated building wall structures in the prior art. It can adapt to the connection of the corner parts of the wall and ensure the overall performance and construction efficiency of the wall.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A prefabricated modular splicing wall structure includes corner wall panels at the corners of the wall, multiple main wall panels on the wall surface, and connecting blocks.

[0008] The corner wall panel and the main wall panel are provided with a first assembly groove on one side and a second assembly groove on the other side; the first assembly groove and the second assembly groove between the corner wall panel and the two opposite sides of the adjacent main wall panel, and between the two opposite sides of two adjacent main wall panels are arranged opposite to each other and are connected; the sidewalls of the first assembly groove and the second assembly groove are fixed with limit rods.

[0009] The connecting block is embedded in the first assembly slot and the second assembly slot and is fastened to the two limiting rods by locking members to connect the corner wall panel and the main wall panel or two adjacent main wall panels.

[0010] The beneficial effects of this utility model are that limiting rods are provided in the first and second assembly slots between the corner wall panel and the main wall panel, and between the opposite side walls of two adjacent main wall panels. The connecting block is embedded in the first and second assembly slots and is fastened to the limiting rods by locking parts. This solution enables rapid assembly of the wall, simplifies the construction process, and improves construction efficiency. It solves the problems of complex splicing and poor stability of prefabricated building wall structures in the prior art, and can adapt to the connection of the corner part of the wall, ensuring the overall performance of the wall and construction efficiency.

[0011] Preferably, the connecting block includes a plate-shaped block and a locking block; the first assembly slot and the second assembly slot are arranged vertically and offset; the plate-shaped block is adapted to the assembly cavity where the first assembly slot and the second assembly slot are joined; both limiting rods are provided at the slot opening ends of the first assembly slot and the second assembly slot and are arranged vertically and offset, and the plate-shaped block is provided with insertion holes corresponding to the limiting rods vertically and vertically; a locking groove is provided on the bottom wall of the first assembly slot or the second assembly slot corresponding to the limiting rod;

[0012] The plate-shaped block is assembled in the assembly cavity; the two limiting rods are inserted into the insertion holes and fastened by the locking member; there are two locking blocks, which are fixed at the upper and lower ends of both sides of the plate-shaped block, and the two locking blocks are locked into the two locking slots in a one-to-one correspondence.

[0013] The beneficial effects of the above technical solution are that the first assembly slot, the second assembly slot, and the slot form a "Z" shaped groove, and both limiting rods are inserted into the plate-shaped block and fastened by locking components. The slot is engaged in the slot, and the splicing method is simple and reliable. Moreover, by using the limiting rods to insert into the plate-shaped block, the plate-shaped block can be embedded in the first and second assembly slots, making the structure more compact. At the same time, the limiting rods can prevent the plate-shaped block from swaying left and right in the limiting slot, ensuring the stability of the connection between the corner wall panel and multiple main wall panels.

[0014] Preferably, the plate-shaped block has a first limiting groove at both its upper and lower ends; the limiting rod is inserted into the first limiting groove. The limiting rod is accommodated by the first limiting groove, resulting in a simple and compact structure.

[0015] Preferably, the upper and lower ends of the locking block are each provided with a second limiting groove, which communicates with the first limiting groove. The second limiting groove connects to the first limiting groove, thereby increasing the cavity of the first limiting groove and facilitating the docking between the connecting block and the limiting rod.

[0016] Preferably, the locking element includes a strip plate and a rod; a groove is formed on the surface of the plate-shaped block; the strip plate is placed in the groove; the rod is fixed to the front panel of the strip plate and penetrates the bottom wall of the groove to be inserted into the limiting rod. The groove accommodates the strip plate, ensuring the smoothness of the wall surface of the spliced ​​wall; the insertion of the rod into the limiting rod achieves the fastening between the connecting block and the main wall panel and the corner wall panel.

[0017] Preferably, it also includes a locking bolt, the threaded end of which penetrates the panel of the strip plate and screws onto the bottom wall of the groove. The locking bolt secures the strip plate to the plate-shaped block.

[0018] Preferably, the strip plate has a relief groove on the side panel away from the plate-shaped block for accommodating the locking bolt. The relief groove accommodates the locking bolt, ensuring that the head of the locking bolt will not protrude from the edge of the plate-shaped block after the strip plate is locked to the plate-shaped block, thus guaranteeing the overall smoothness of the spliced ​​wall.

[0019] Preferably, the device further includes two locking blocks, which are respectively fixed to the upper and lower ends of the strip-shaped plate. The panel of the plate-shaped block has a first receiving groove communicating with the first limiting groove, and the locking block has a second receiving groove communicating with the first receiving groove. The locking block enters the second limiting groove through the first and second receiving grooves and abuts against the limiting rod. The receiving groove corresponds to the locking groove position. Since the limiting rod is inserted into the first limiting groove, a gap will appear between the limiting rod and the second limiting groove. The locking block, by entering the second limiting groove through the receiving groove, can fill this gap, preventing the limiting rod from detaching from the plate-shaped block and improving the stability of the wall assembly.

[0020] Preferably, the corner wall panel or the main wall panel is fixed with positioning posts at the top and bottom of the second assembly groove, and a positioning groove adapted to the positioning posts is opened at the side of the first assembly groove. The positioning posts and positioning grooves realize the positioning and docking during the wall splicing process.

[0021] Preferably, both the corner wall panel and the main wall panel are prefabricated wall panels.

[0022] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a prefabricated modular splicing wall structure, which has the following beneficial effects:

[0023] 1. Rapid assembly, improved construction efficiency: The wall structure of this utility model uses prefabricated wall panels, which are then rapidly assembled on the construction site, greatly simplifying the construction process and improving construction efficiency; at the same time, the design of connecting blocks and locking parts makes the connection between wall panels easier and faster, further shortening the construction cycle.

[0024] 2. Stable structure and improved wall performance: The wall structure of this utility model achieves tight connection and stable fixation between wall panels through the combined use of connecting blocks and locking parts; the ingenious design of components such as limiting rods, clips, and insert rods enables the wall panels to interlock and support each other during splicing, thereby improving the overall stability and seismic performance of the wall.

[0025] 3. Easy to disassemble and maintain: The wall structure of this utility model is very easy to disassemble. Simply loosen the locking bolts to easily separate the wall panels. This easy disassembly feature not only facilitates the maintenance and replacement of the wall, but also makes the wall structure more flexible when it needs to be modified or expanded.

[0026] 4. Environmentally friendly and energy-saving, reducing construction costs: The wall structure of this utility model adopts a modular design, which can greatly reduce on-site wet work and reduce the generation of construction waste, which is beneficial to environmental protection; at the same time, the production and transportation of prefabricated wall panels are also more efficient, which can further reduce construction costs.

[0043] Participate in the attached Figures 1-8 This utility model embodiment discloses a prefabricated modular splicing wall structure, including a corner wall panel 1 corresponding to the corner of the wall, multiple main wall panels 2 corresponding to the wall surface, and connecting blocks 3;

[0044] The corner wall panel 1 and the main wall panel 2 are provided with a first assembly groove 4 on one side and a second assembly groove 5 on the other side. The first assembly groove 4 and the second assembly groove 5 between the corner wall panel 1 and the opposite sides of the adjacent main wall panel 2, and between the opposite sides of two adjacent main wall panels 2 are arranged opposite to each other and connected. Limiting rods 7 are fixed to the side walls of the first assembly groove 4 and the second assembly groove 5.

[0045] The connecting block 3 is embedded in the first assembly groove 4 and the second assembly groove 5 and is fastened to the two limiting rods 7 by locking members to connect the corner wall panel 1 and the main wall panel 2 or two adjacent main wall panels 2.

[0046] In this embodiment, both the corner wall panel 1 and the main wall panel 2 are prefabricated wall panels.

[0047] See appendix Figures 1-4 The connecting block engages with the main wall panel and the corner wall panel through the first and second assembly slots. The connecting block and the limiting rod are fastened by the locking device, which can lock the connecting block, the main wall panel and the corner wall panel to form a stable spliced ​​wall structure.

[0048] In this embodiment, the connecting block 3 includes a plate-shaped block 31 and a locking block 33; the first assembly groove 4 and the second assembly groove 5 are arranged vertically and offset; the plate-shaped block 31 is adapted to the assembly cavity where the first assembly groove 4 and the second assembly groove 5 are connected; two limiting rods 7 are provided at the groove ends of the first assembly groove 4 and the second assembly groove 5 and are arranged vertically and offset, and the plate-shaped block 31 is provided with insertion holes corresponding to the limiting rods 7 vertically and vertically; a locking groove 6 is provided on the bottom wall of the first assembly groove 4 or the second assembly groove 5 corresponding to the limiting rod 7.

[0049] The plate-shaped block 31 is assembled in the assembly cavity; two limiting rods 7 are inserted into the insertion holes and fastened by locking parts; there are two locking blocks 33, which are fixed at the upper and lower ends of both sides of the plate-shaped block 31 respectively, and the two locking blocks 33 are locked into the two locking slots 6 one by one.

[0050] Participate in the attached Figure 5 and 7 The locking blocks are fixed to both ends of the plate-shaped block in a diagonal arrangement. Slots are opened between the two limiting rods and the bottom walls of the first and second assembly slots. These two slots, along with the first and second assembly slots, form a "Z"-shaped groove. The locking blocks and the plate-shaped block form a Z-shaped block that matches the "Z"-shaped groove. The locking blocks and slots are compatible, and the plate-shaped block is compatible with the first and second assembly slots. The connecting blocks and limiting rods are fastened by locking components. The wall panels are quickly assembled through snap-fit ​​and locking mechanisms, greatly simplifying the construction process, improving construction efficiency, and shortening the construction period.

[0051] In order to further optimize the above technical solution and ensure that the limiting rod does not affect the engagement of the plate-shaped block in the first and second assembly slots, the upper and lower ends of the plate-shaped block 31 are provided with first limiting slots 311; the limiting rod 7 is inserted into the first limiting slot 311.

[0052] The first limiting groove, which extends through the upper and lower ends of the plate-shaped block, accommodates the limiting rod, ensuring the interlocking performance between the plate-shaped block and the first and second assembly grooves.

[0053] To further optimize the above technical solution, the first limiting groove is enlarged to facilitate the docking between the connecting block and the limiting rod. The upper and lower ends of the card block 33 are provided with second limiting grooves 331, which are connected to the first limiting groove 311.

[0054] In this embodiment, the locking component includes a strip plate 32 and a plug rod 35; a groove 313 is provided on the panel of the plate-shaped block 31; the strip plate 32 is placed in the groove 313; the plug rod 35 is fixed on the panel of the strip plate 32 and passes through the bottom wall of the groove 313 to be inserted into the limiting rod 7.

[0055] like Figure 6 and 7As shown, the block 31 and the limiting rod 7 are connected by a strip plate 32; the limiting rod 7 has a limiting hole 71; the upper and lower ends of the groove bottom wall of the groove 313 are provided with insertion holes 314 that correspond to the limiting blocks 71 on the two limiting rods 7; the insertion rod 35 passes through the insertion hole 315 and is inserted into the limiting hole. The side panel of the strip plate 32 away from the insertion rod 35 is on the same plane as the panel of the plate block 31. The structure is compact, beautiful and smooth. By using the cooperation of the insertion rod 35 and the limiting hole 71, the connecting block 3 is spliced ​​with the main wall panel 2 and the corner wall panel 1.

[0056] To ensure the strip plate can be inserted into the two limiting rods, the width of the strip plate is more than twice the width of the limiting rods. The two limiting rods are staggered vertically, and the strip plate can completely cover the two limiting rods. Furthermore, the two insertion holes on the strip plate corresponding to the limiting holes are staggered to ensure that the strip plate can be inserted into the two limiting rods.

[0057] To further optimize the above technical solution, improve the interlocking performance between the plate-shaped block and the corner wall panel and the main wall panel, and ensure the limiting performance of the limiting rod on the plate-shaped block, a locking block 34 is also included. There are two locking blocks 34, which are respectively fixed to the upper and lower ends of both sides of the strip plate 32. The panel of the plate-shaped block 31 has a first receiving groove 312 that connects to the first limiting groove 311, and the locking block 33 has a second receiving groove 332 that connects to the first receiving groove 312. The locking block 34 enters the second limiting groove 331 through the first receiving groove 312 and the second receiving groove 332 and abuts against the limiting rod 7.

[0058] The first and second receiving grooves are interconnected and correspond to the corresponding slot positions. Locking blocks are fixed diagonally to both ends of the strip panel, forming Z-shaped blocks. The thickness of the locking blocks is greater than the thickness of the strip panel. The locking blocks are engaged within the receiving grooves, and the strip panel abuts against the concave bottom wall of the groove. Through engagement and insertion rods, the stability of the strip panel's connection with the limiting rod within the groove is ensured. The engagement of the locking blocks within the receiving grooves prevents the strip panel from falling off. By filling the gaps between the receiving grooves, limiting grooves, and limiting rods with the locking blocks, the two limiting rods cannot detach from the plate-shaped block, ensuring the interlocking performance between the plate-shaped block and the main wall panel and corner wall panel, thus improving the stability of the splicing.

[0059] To further optimize the above technical solution and ensure the stability of the connection between the strip plate and the plate-shaped block, a locking bolt 36 is also included. The threaded end of the locking bolt 36 penetrates the panel of the strip plate 32 and is screwed into the bottom wall of the groove 313.

[0060] A locking hole 315 is provided in the middle of the bottom wall of the groove 313, and a threaded hole 322 is provided in the middle of the panel of the strip plate 32. The threaded end of the locking bolt 36 is screwed into the threaded hole 322 and the locking hole 315 in sequence to lock the strip plate 32 and the plate block 31, so that they form a stable Z-shaped connecting block.

[0061] To further optimize the above technical solution and ensure the aesthetics of the connecting block, a relief groove 321 for accommodating the locking bolt 36 is provided on the side panel of the strip plate 32 away from the plate block 31.

[0062] In other specific embodiments, to ensure accurate positioning of the splicing between the main wall panels and between the main wall panels and the corner wall panels, the corner wall panel 1 or the main wall panel 2 is fixed with positioning posts 8 at the top and bottom of the second assembly groove 5, and the side end of the first assembly groove 4 is provided with positioning grooves 9 that are adapted to the positioning posts 8.

[0063] The splicing wall structure provided in this embodiment allows for the prefabrication of required wall panels before construction, followed by delivery to the construction site for on-site assembly. The main body of the wall is assembled using multiple main wall panels. At wall corners, corner wall panels connect the main wall panels on both sides, thus completing the overall splicing process of the wall. The specific splicing process is as follows:

[0064] Insert the connecting block into the first assembly slot of one of the main wall panels or corner wall panels from the top side. At this time, the locking block enters the first rectangular slot, one side of the connecting block abuts against one side of the main wall panel, and the limiting rod corresponds to the second limiting slot.

[0065] Then move the connecting block down so that the limiting rod is inserted into the second limiting groove. Then move the connecting block laterally. At this time, the locking block on one side of the connecting block is fully engaged with the locking groove. The plate-shaped block of the connecting block is located in the first assembly groove. In this state, the limiting rod moves into the first limiting groove, and the connecting block is connected to one of the main wall panels.

[0066] Move the other main wall panel from top to bottom, first aligning the limiting rod with the second limiting groove, then move it laterally to complete the connection of the two main wall panels;

[0067] Next, the strip plate is brought into contact with the bottom wall of the groove. At this time, the locking block enters the first and second receiving grooves. The locking block is located on the side of the limiting rod near the slot, so that the two limiting rods cannot be disengaged. The insertion rod enters the limiting hole on the limiting rod to achieve the engagement of the insertion rod and the limiting rod, and the limiting rod is limited again. The locking bolt is rotated, and the locking bolt engages the strip plate with the bottom wall of the groove on the plate block, thereby locking the strip plate and the plate block together and completing the final fixation between the connecting block and the main wall panel and the corner wall panel.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
