Description

Technical Field

[0001] This utility model relates to the field of steel structure wall panel technology, and in particular to a steel structure prefabricated wall panel node. Background Technology

[0002] Under the wave of industrialization in construction, prefabricated buildings have become the core direction for the transformation and upgrading of my country's construction industry due to their advantages such as high construction efficiency, green environmental protection, and controllable quality. Among them, steel structures occupy an important position in prefabricated buildings due to their high strength, light weight, and excellent seismic performance. As the enclosure or load-bearing component of steel structure buildings, the connection nodes between the wall panels and the main structure are the key links affecting the overall performance of the building.

[0003] However, existing steel structure prefabricated wall panel joints have the following disadvantages:

[0004] (1) In traditional steel structure buildings, the installation of wall panels at corners requires on-site cutting and grinding of the wall panels to match the angle, which consumes a lot of manpower and time, and it is difficult to form multi-directional constraints. Under the action of earthquakes, wind loads, etc., the wall panels are prone to loosening and node deformation due to stress concentration, which may even affect the overall stability of the building.

[0005] (2) Traditional nodes fix multiple wall panels independently, lacking a synchronous constraint mechanism. Relative sliding or separation may occur between wall panels or between wall panels and the main structure, making it difficult to form a unified whole under stress. Under load, node failure may occur due to excessive local stress.

[0006] Therefore, this utility model provides a steel structure prefabricated wall panel node. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The problem solved by this utility model is to provide a highly practical prefabricated steel structure wall panel node, which solves the problems mentioned in the background art, such as consuming a lot of manpower and time, being prone to wall panel loosening due to stress concentration, node deformation, and difficulty in forming a unified whole under stress.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: a steel structure prefabricated wall panel node, including a connector, wherein the top of the connector has four sides with grooves, the inner sidewall of the groove is slidably connected to a connecting block, one side of the connecting block is fixedly connected to a wall panel, the top of the connector is provided with a fixing block, the top of the fixing block is provided with multiple countersunk holes, the inner sidewall of the countersunk holes is provided with screws, and the top of the connector is provided with multiple first threaded grooves that are compatible with the screws.

[0011] Optionally, L-shaped plates are provided on both sides of the front and back of the wall panel. One side of the L-shaped plate contacts the surface of the connector. Multiple round holes are opened on the surface of the L-shaped plate, and bolts are installed inside the round holes. The front and back of the wall panel and the surface of the connector are all provided with second threaded grooves that are compatible with the bolts. The L-shaped plates are attached to the wall panel and the connector respectively through the flanges on both sides. With the fastening effect of the bolts, a bidirectional force-bearing reinforcement structure is formed, which enhances the connection rigidity of the two.

[0012] Optionally, a T-shaped guide strip is fixedly connected to the inner wall of the slide, and a T-shaped slide groove adapted to the T-shaped guide strip is opened on the other side of the connecting block, providing a precise guiding reference for the sliding of the connecting block, ensuring that the wall panel moves along the preset trajectory during installation, greatly reducing the alignment error during assembly and improving construction efficiency.

[0013] Optionally, a soft pad is provided between the connector and the fixing block. The soft pad is made of rubber. When the soft pad is compressed, it can fill the tiny gap between the two, effectively blocking the intrusion of rainwater, dust and other impurities, and improving the waterproof and dustproof performance of the joint.

[0014] Optionally, a positioning block is fixedly connected to the bottom of the fixing block, and a positioning groove adapted to the positioning block is opened on the top of the connector. The precise matching between the positioning block and the positioning groove can quickly achieve alignment with the connector during the installation of the fixing block, reduce on-site adjustment time, and improve construction efficiency.

[0015] Optionally, a washer is provided on the inner bottom wall of the countersunk hole. The washer is fitted onto the surface of the screw to evenly distribute the screw's tightening force onto the fixing block, preventing the surface of the fixing block from being dented or damaged due to excessive local pressure, thus protecting the integrity of the component.

[0016] (III) Beneficial Effects

[0017] This utility model provides a steel structure prefabricated wall panel node, which has the following beneficial effects:

[0018] 1. This steel structure prefabricated wall panel node, through the cooperation of the sliding grooves distributed on the four sides of the connector and the T-shaped guide strip, allows wall panels in different directions to be quickly embedded into adjacent sliding grooves with the help of connecting blocks. There is no need for complicated on-site measurement or cutting, and it directly matches the angle requirements of the building corner. The T-shaped guide structure ensures the stable sliding of the connecting block while strictly limiting the vertical displacement, ensuring the verticality and positional accuracy of the wall panel at the corner, which greatly improves the assembly efficiency of the corner. The L-shaped plate double-fits and fixes the adjacent wall panel and the connector at the corner, forming a multi-directional force constraint system, which effectively disperses the stress concentration at the corner.

[0019] 2. This steel structure prefabricated wall panel node, with its T-shaped guide strip and sliding engagement with the connecting block, provides a unified guiding benchmark for the installation of multiple wall panels, ensuring the consistency of the installation axis of each wall panel and reducing assembly errors from the source. The fixing block, through the precise alignment of the positioning block and the positioning groove, further ensures the synchronous pressing of all connecting blocks, avoiding overall structural misalignment caused by the fixing deviation of a single wall panel. It is suitable for multi-wall panel connection scenarios such as cross intersections and T-shaped interfaces, improving the assembly quality of complex nodes. After the fixing block is locked with screws, the longitudinal pressure on the connecting block and the lateral constraint of the T-shaped structure work together to limit the sliding or detachment of the wall panel in the groove, integrating multiple dispersed wall panels into a unified whole under stress.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 4This utility model provides a technical solution: a steel structure prefabricated wall panel node, including a connector 1, the four sides of the top of which have grooves to provide installation tracks for the connecting block 2, which is a mechanical transmission bridge between the wall panel 3 and the main steel structure. The four sides of the top of the connector 1 are provided with grooves to provide precise guidance and limit for the connecting block 2, so that the connecting block 2 can slide stably in a preset direction. The inner side wall of the groove is slidably connected to the connecting block 2, which transmits the load on the wall panel 3 to the connector 1. At the same time, through the sliding cooperation with the groove, the wall panel 3 can be conveniently installed and its position adjusted. The wall panel 3 is fixedly connected to one side of the connecting block 2. The top of the connector 1 is provided with a fixing block 4. The top of the fixing block 4 is provided with multiple countersunk holes. The inner side wall of the countersunk holes is provided with screws 5. The screws 5 pass through the countersunk holes of the fixing block 4 and cooperate with the first thread groove of the connector 1. The fixing block 4 and the connector 1 are firmly connected by the thread locking force. The top of the connector 1 is provided with multiple first thread grooves that are compatible with the screws 5.

[0027] Both sides of the front and back of the wall panel 3 are provided with L-shaped plates 6. One side of the L-shaped plate 6 is in contact with the surface of the connector 1. Multiple round holes are opened on the surface of the L-shaped plate 6, and bolts 7 are installed inside the round holes. The front and back of the wall panel 3 and the surface of the connector 1 are provided with second threaded grooves that are compatible with the bolts 7. The L-shaped plate 6 is attached to the wall panel 3 and the connector 1 respectively through the flanges on both sides. With the fastening effect of the bolts 7, a bidirectional force-bearing reinforcement structure is formed to enhance the connection rigidity of the two.

[0028] The inner wall of the slide is fixedly connected with a T-shaped guide strip 8, and the other side of the connecting block 2 is provided with a T-shaped slide groove that matches the T-shaped guide strip 8, which provides a precise guiding reference for the sliding of the connecting block 2, ensuring that the wall panel 3 moves along the preset trajectory during installation, greatly reducing the alignment error during assembly and improving construction efficiency.

[0029] A soft pad 9 is provided between the connector 1 and the fixing block 4. The soft pad 9 is made of rubber. When the soft pad 9 is compressed, it can fill the tiny gap between the two, effectively blocking the intrusion of rainwater, dust and other impurities, and improving the waterproof and dustproof performance of the joint.

[0030] The bottom of the fixing block 4 is fixedly connected to the positioning block 10, and the top of the connector 1 is provided with a positioning groove that matches the positioning block 10. The precise fit between the positioning block 10 and the positioning groove can quickly achieve alignment with the connector 1 when the fixing block 4 is installed, reducing on-site adjustment time and improving construction efficiency.

[0031] A washer 11 is provided on the inner bottom wall of the countersunk hole. The washer 11 is fitted onto the surface of the screw 5 to evenly distribute the tightening force of the screw 5 onto the fixing block 4, so as to avoid the surface of the fixing block 4 from being dented or damaged due to excessive local pressure, thus protecting the integrity of the component.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: When wall panel 3 needs to be installed at the corner, wall panels 3 in different directions can be embedded into the grooves on the adjacent sides of connector 1 through connecting blocks 2. Since the grooves are distributed along the four sides of connector 1, they match the angle requirements of the building corner. Connecting blocks 2 are slidably connected to the inner wall of the groove, and the T-shaped guide strip 8 in the groove cooperates with the T-shaped groove of connecting block 2. This ensures that connecting block 2 slides stably in the groove and limits the vertical displacement of connecting block 2, ensuring the verticality and positional accuracy of wall panel 3 when installed at the corner. At the same time, L-shaped plates 6 can be attached to the side of adjacent wall panels 3 at the corner and the surface of connector 1 respectively, and further fixed by bolts 7, enhancing the integrity and anti-torsion performance of the corner node and preventing loosening due to concentrated force at the corner.

[0034] The second step: Slide the connecting blocks 2 of each wall panel 3 into the corresponding T-shaped guide strips 8 along the corresponding slide grooves. The T-shaped structure guides and prevents the connecting blocks 2 from falling out of the slide grooves, while ensuring that the installation axes of the wall panels 3 are consistent, reducing assembly errors. After all the wall panels 3 are positioned, cover them with the fixing blocks 4. The positioning blocks 10 at the bottom of the fixing blocks 4 are embedded in the positioning grooves of the connectors 1, achieving precise alignment between the fixing blocks 4 and the connectors 1. Then, lock the fixing blocks 4 and the connectors 1 with the screws 5 in the countersunk holes. The pressure of the fixing blocks 4 acts on the top of the connecting blocks 2, restricting the sliding of the connecting blocks 2 in the slide grooves, thereby fixing multiple wall panels 3 simultaneously on the connectors 1 to form a stable multi-panel connection system.
