Description

Technical Field

[0001] This utility model relates to the field of aerated concrete wall panel installation technology, and in particular to a modular hybrid connection device for autoclaved aerated concrete wall panels. Background Technology

[0002] Autoclaved aerated concrete (AAC) wall panels are increasingly used in prefabricated buildings due to their advantages such as lightweight, heat insulation, and fire resistance. The existing connection methods between wall panels mostly rely on pre-embedded steel bars in the panels, and the connection between adjacent wall panels is achieved by welding or pouring concrete during installation.

[0003] A search revealed a prior art autoclaved aerated concrete wall panel (publication number: CN120273463A), comprising: A plate body, wherein a connecting groove is provided on one side of the plate body; An internal support assembly, comprising vertical and horizontal reinforcing bars, which are distributed intersectingly within the slab. Multiple connecting reinforcing bars are arranged in two rows on the side of the slab away from the connecting groove. The end of the connecting reinforcing bar closest to the slab is connected to the corresponding horizontal reinforcing bar. When two adjacent slabs are spliced, the connecting reinforcing bars are inserted into the inside of the connecting groove.

[0004] The construction process is complicated, requires high skills from on-site workers, and the quality is not easy to control. Since the connector consists of multiple deformable claws, the connection needs to be aligned and squeezed into the groove one by one, which makes the installation process complicated and inconvenient. The deformable nature also results in poor strength after installation.

[0005] To this end, we propose a modular hybrid connection device for autoclaved aerated concrete wall panels. Utility Model Content

[0006] The present invention mainly addresses the aforementioned technical problems of inconvenient installation and poor strength by providing a modular hybrid connection device for autoclaved aerated concrete wall panels.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a modular mixing and connection device for autoclaved aerated concrete wall panels, comprising: The frame and two wall panels respectively set on both sides of the frame; A longitudinal connection structure is provided on the top and bottom surfaces of the frame to vertically connect two frame pieces. The longitudinal connection structure includes longitudinal insertion holes and connectors. Longitudinal insertion holes are provided on both the top and bottom surfaces of the frame, and the connectors can be inserted into the longitudinal insertion holes. A horizontal connecting structure is provided, with two sides of the frame for locking two horizontally connected frames. The horizontal connecting structure includes a main body and ribs. A lateral connecting groove is provided on each side of the frame. A slidable rib is provided on each side of the main body. The ribs and the main body together form a wedge-shaped structure. The wedge-shaped structure can be inserted into the lateral connecting groove to lock the two frames.

[0008] In a preferred embodiment of this utility model, the longitudinal insertion hole is a horizontally cross-section I-shaped groove, the depth of the longitudinal insertion hole is less than the height of the frame, and the connector forms a block that fits with the longitudinal insertion hole with a clearance, the height of the connector being greater than the depth of the longitudinal insertion hole.

[0009] In a preferred embodiment of this utility model, the lateral connecting groove is a groove with a trapezoidal horizontal cross-section, and the depth of the lateral connecting groove is equal to the height of the frame.

[0010] In a preferred embodiment of this utility model, the transverse connection structure further includes an extrusion block and an adjusting screw. The adjusting screw is rotatably connected to the main body, and the extrusion block is threadedly connected to the adjusting screw. The adjusting screw can push the two ribs to move towards each other.

[0011] In a preferred embodiment of this utility model, the main body is a rectangular rod, with two ribs slidably disposed on both sides of the main body.

[0012] In a preferred embodiment of this utility model, the extrusion block is a trapezoidal block with a threaded hole through it, and the adjusting screw can engage with the threaded part of the extrusion block and push the extrusion block to move between the two ribs.

[0013] In a preferred embodiment of this utility model, the transverse connection structure further includes guide rods, at least two guide rods are fixedly installed on the side wall of the rib, the main body is provided with a sliding groove that fits the guide rods with a clearance, and the guide rods are slidably disposed in the sliding groove.

[0014] This utility model provides a modular mixing and connection device for autoclaved aerated concrete wall panels. It has the following beneficial effects: 1. This modular hybrid connection device for autoclaved aerated concrete (AAC) wall panels prefabricates the wall panels and frame into standard modules, requiring only two simple steps on-site: "plugging in" and "locking." Longitudinally, rapid positioning and initial connection are achieved through the plugging of connectors into I-shaped holes; laterally, the wedge-shaped structure expands and locks by rotating the adjusting screw. The entire installation process requires no welding or wet work, reducing the traditional connection work that takes hours to minutes, significantly improving construction efficiency. This invention employs a hybrid connection mechanism combining longitudinal positioning plugging and lateral mechanical locking. The longitudinal connection provides excellent shear and pull-out resistance, ensuring effective transmission of vertical loads; while the lateral wedge-shaped locking structure generates significant friction through the tight interlocking of ribs and trapezoidal grooves, forming a reliable tensile and bending joint. This hybrid connection method collectively ensures the excellent integrity and seismic performance of the wall panel system, with reliable connections and good structural integrity.

[0015] 2. This modular hybrid connection device for autoclaved aerated concrete wall panels, through longitudinal insertion and fitting gaps and a certain adjustment range of wedge structure, enables the device to have good fault tolerance, effectively absorb the small dimensional errors generated during the production, transportation and installation of wall panels and frames, reduce installation difficulty, ensure the flatness of the final wall surface, and has strong fault tolerance and high installation accuracy.

[0016] 3. This modular hybrid connection device for autoclaved aerated concrete wall panels, through the cooperation of guide rods and sliding grooves in the transverse connection structure, ensures that the ribs will not deflect during the sliding process and can only perform precise linear motion. The adjusting screw pushes the trapezoidal extrusion block, converting the rotational motion into the linear expansion of the ribs. The mechanical principle is clear, the force transmission path is well-defined, ensuring the stability and repeatability of the locking force. The structural design is ingenious, and the force path is clear. Attached Figure Description

[0019] A modular hybrid connection device for autoclaved aerated concrete wall panels, such as Figure 1 and Figure 2 As shown, it includes: The frame 10 and two wall panel bodies 11 respectively disposed on both sides of the frame 10; A longitudinal connection structure is provided on the top and bottom surfaces of the frame 10 to vertically connect the two frames 10. The longitudinal connection structure includes a longitudinal insertion hole 12 and a connector 13. The top and bottom surfaces of the frame 10 are provided with longitudinal insertion holes 12, and the connector 13 can be inserted into the longitudinal insertion hole 12. In this solution, a wall panel body 11 is installed on the front and rear walls of the frame 10 to form a module. In order to achieve vertical connection between the two modules, the connector 13 is inserted into the longitudinal insertion hole 12 of one of the frames 10, and then the longitudinal insertion hole 12 of the other frame 10 is aligned with the protruding connector 13 and inserted. In this way, the two frames 10 can be vertically connected, and the frame 10 as a whole is symmetrical, which greatly improves the standardization and convenience of producing the frame 10.

[0020] like Figure 2 and Figure 3 As shown, a transverse connection structure is provided, with two sides of the frame 10 for locking two horizontally connected frames 10. The transverse connection structure includes a main body 20 and ribs 21. A lateral connection groove 14 is opened on each side of the frame 10. A slidable rib 21 is provided on each side of the main body 20. The ribs 21 and the main body 20 together form a wedge structure. The wedge structure can be inserted into the lateral connection groove 14 to lock the two frames 10. The longitudinal insertion hole 12 is a horizontally cross-section I-shaped groove. The depth of the longitudinal insertion hole 12 is less than the height of the frame 10. The connector 13 forms a block that fits with the longitudinal insertion hole 12 with clearance. The height of the connector 13 is greater than the depth of the longitudinal insertion hole 12. The lateral connection groove 14 is a horizontally cross-section trapezoidal groove. The depth of the lateral connection groove 14 is the same as the height of the frame 10. like Figure 3 and Figure 4 As shown, the transverse connection structure also includes an extrusion block 22 and an adjusting screw 23. The adjusting screw 23 is rotatably connected to the main body 20, and the extrusion block 22 is threadedly connected to the adjusting screw 23. The adjusting screw 23 can push the two ribs 21 to move towards each other. The main body 20 is a rectangular rod, and the two ribs 21 are slidably arranged on both sides of the main body 20. The extrusion block 22 is a trapezoidal block, and a threaded hole is opened through the extrusion block 22. The adjusting screw 23 can be threadedly engaged with the extrusion block 22 and push the extrusion block 22 to move between the two ribs 21. The transverse connection structure also includes a guide rod 24. At least two guide rods 24 are fixedly installed on the side wall of the rib 21. The main body 20 is provided with a sliding groove that is clearance-fitted with the guide rod 24, and the guide rod 24 is slidably arranged in the sliding groove. In this scheme, when the extrusion block 22 is not installed with the guide rod 24, the two ribs 21 are close to the sides of the main body 20. At this time, the joint formed by the main body 20 and the ribs 21 can be horizontally placed into the lateral connecting groove 14 of the two horizontally adjacent frames 10. Then, the extrusion block 22 is placed on top of the main body 20. With the help of a hex wrench, the adjusting screw 23 is turned. The adjusting screw 23 pushes the extrusion block 22 into the space between the two ribs 21. The inclined surface of the extrusion block 22 pushes the two ribs 21 to move towards each other. The ribs 21 drive the corresponding guide rod 24 to slide in the groove. The two ribs 21 move away from each other until they touch the inner wall of the lateral connecting groove 14. At this time, the main body 20 and the two ribs 21 form a wedge structure to lock the two horizontally adjacent frames 10.

[0021] The working principle of this utility model is as follows: First, two autoclaved aerated concrete wall panel bodies 11 are fixedly installed on both sides of the metal frame 10 in the factory to form a complete and standardized wall panel module unit. The top and bottom surfaces of the module are pre-drilled with longitudinal insertion holes 12, and the two sides are pre-drilled with lateral connection grooves 14.

[0022] Vertical (vertical) installation: When vertically splicing the upper and lower wall panels, the operator inserts the lower half of the connector 13 into the longitudinal insertion hole 12 at the top of the lower wall panel module. Since the height of the connector 13 is greater than the depth of the insertion hole, its upper end will be exposed. Then, the longitudinal insertion hole 12 at the bottom of the upper wall panel module is aligned with the exposed upper end of the connector 13, and the module is placed downwards to complete the quick alignment and initial connection of the upper and lower modules. The I-shaped insertion hole and the shape of the connector effectively limit the horizontal displacement.

[0023] Horizontal (left-right) installation: When horizontally splicing adjacent wall panels on the left and right sides, the operation procedure is as follows: Insertion: The components of the horizontal connection structure (the main body 20 and the two ribs 21 in the retracted state) are horizontally inserted into the lateral connection slots 14 of the two adjacent frames 10.

[0024] Locking: Place the extrusion block 22 above the main body 20, and use a tool to rotate the adjusting screw 23. The rotation of the adjusting screw 23 drives the extrusion block 22, which is threaded with it, to move downward.

[0025] Expansion: The trapezoidal inclined surface at the lower end of the extrusion block 22 contacts the inclined surface at the upper end of the two ribs 21 and continuously applies downward pressure. This pressure is decomposed into a horizontal component, which forces the two ribs 21 to move in opposite directions (i.e., expand outward) along the constraint of the guide rod 24 and the sliding groove on the main body 20.

[0026] Consolidation: The outer surfaces of the two ribs 21 eventually abut tightly against the trapezoidal inner inclined surface of the lateral connecting groove 14. Through the self-locking effect between the inclined surfaces, a huge normal pressure and friction are generated, thereby firmly locking the two adjacent frames 10 together to form a stable horizontal connection.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
