Description

Technical Field

[0001] This utility model relates to the field of precast slab connection technology, specifically to the tenon and mortise installation structure of four types of reinforced concrete precast slabs. Background Technology

[0002] Prefabricated construction is an important development direction in the modern construction industry. Its core lies in the pre-production of building components in a factory, followed by transportation to the site for assembly. As the main horizontal load-bearing components in a building, the connection performance between prefabricated slabs and the main structure is crucial, directly affecting the structure's integrity, stability, and seismic performance. Mortise and tenon joints, a clever connection method originating from traditional Chinese wooden architecture, achieves connection through the interlocking of protrusions and grooves on components. In recent years, this method has been introduced into the connection of reinforced concrete prefabricated components to achieve efficient and reliable assembly construction. However, existing mortise and tenon joint structures for prefabricated slabs still face some technical bottlenecks that urgently need improvement in practical applications.

[0003] The existing tenon-and-mortise installation structure for the four types of reinforced concrete precast slabs has the following shortcomings: 1. Many existing mortise and tenon connections rely on manual reinforcement or simple pinning after the components are in place, lacking an efficient and automatic locking mechanism. After the tenon is inserted into the mortise, the tightness of the connection point often depends on the experience of the construction workers, making it difficult to guarantee a consistent locking effect for each connection. There is a risk of loosening due to vibration or external force, affecting the initial reliability of the connection.

[0004] 2. When it is necessary to correct misaligned precast slabs, the existing mortise and tenon joint separation process is extremely inconvenient. The tightly fitted mortise and tenon joints generate significant static friction and interlocking forces, typically requiring strong manual prying to separate them. This process is not only time-consuming and labor-intensive, but more importantly, the rough handling can easily cause irreversible damage to critical components such as the tenon or mortise, potentially rendering the entire precast slab unusable, increasing maintenance costs and construction safety risks. Utility Model Content

[0005] The purpose of this utility model is to provide a tenon and mortise installation structure for four types of reinforced concrete precast slabs.

[0006] To achieve this objective, the present invention adopts the following technical solution: It provides four types of precast reinforced concrete slab tenon and mortise installation structures, including wall panels, as well as connection mechanisms and auxiliary mechanisms; The connecting mechanism is set on the outer wall of the wall panel. The connecting mechanism includes a tenon and mortise assembly and a locking assembly. The tenon and mortise assembly is set on the outer wall of the wall panel, and the locking assembly is set on the tenon and mortise assembly. The auxiliary mechanism is installed on the outer wall of the wall panel. The auxiliary mechanism includes an external support component and a reinforcing component. The external support component is installed on the tenon and mortise component, and the reinforcing component is installed on the outer wall of the wall panel.

[0007] Preferably, the tenon and mortise assembly includes a tenon plate and a mortise groove, with the tenon plate fixedly installed on the outer wall of the wall panel and the mortise groove formed on the outer wall of the wall panel.

[0008] Preferably, the locking assembly includes three mounting slots, three mounting bases, six first springs, six retaining seats, and six retaining grooves. Each mounting slot is formed on the outer wall of the tenon plate. The three mounting bases are fixedly installed inside the three mounting slots. The six first springs are fixedly installed on both sides of the outer wall of the three mounting bases. The six retaining seats are fixed to the other end of the six first springs. The six retaining grooves are formed on both sides of the inner wall of the mortise.

[0009] Preferably, all six card holders are made of alloy material, and the outer surface of each of the six card holders is provided with a beveled surface.

[0010] Preferably, the corners of the mortise are all provided with rounded corners, which are in conjunction with the beveled surface.

[0011] Preferably, the external support assembly includes a connecting groove, three second springs, and a top block. The connecting groove is formed on the outer wall of the tenon plate, each second spring is fixedly installed inside the connecting groove, and the top block is fixedly installed at the other end of the three second springs.

[0012] Preferably, the reinforcing component includes six reserved slots and a filling port, the six reserved slots being respectively opened inside six slots, and the filling port being opened on the outer wall of the wall panel.

[0013] The beneficial effects of this utility model are: 1. This connection structure achieves automatic locking and enhanced strength of the wall panel connection through the coordinated operation of locking and tenon / mortise components. The core mechanism involves the locking component automatically engaging when the tenon of one wall panel is inserted into the mortise of another. During insertion, the retainer on the tenon is compressed by the rounded corner of the mortise, pressing down on the first spring and retracting into the mounting groove. When the tenon is fully inserted and the retainer aligns with the mounting groove, the spring force is released, instantly ejecting the retainer, leaving it half-engaged in the retainer and half-remaining in the mounting groove, acting like an automatic latch. This completes the mechanical interlock between the two wall panels, effectively enhancing the horizontal connection strength. Furthermore, the design includes provisions for strength enhancement. Once the connection is confirmed to be durable and does not require disassembly, cement grout can be injected into the mortise through the filling port on the wall panel. The cement grout fills all gaps between the tenon and the mortise, hardening to form a unified structure that significantly improves the rigidity and shear strength of the connection, allowing multiple wall panels to better cooperate in vertical stress distribution. If disassembly is required, the card holder can be pushed back by inserting a steel rod into the reserved slot, achieving a flexible unity of reversible connection and permanent reinforcement.

[0014] 2. This design integrates an external support component into the auxiliary mechanism, primarily for the safe and efficient separation of wall panels when needed. The core of this component is an energy mechanism pre-compressed within the connection. When the tenon is fully inserted into the mortise, the inner wall of the mortise continuously compresses the top block in the external support component, thus storing energy in the second spring. When a steel bar is inserted through the pre-drilled slot of the reinforcing component, releasing the locking mechanism, the stored elastic potential energy of the second spring is released instantaneously, providing a controllable, directional thrust to the adjacent wall panels through the top block. This thrust effectively overcomes any static friction or slight adhesion between the wall panel connection surfaces, assisting in a smooth separation of a safe distance, greatly reducing the labor intensity and operational risks of manual prying. This design effectively improves the efficiency and safety of construction error correction. Attached Figure Description

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0019] Reference Figures 1 to 6 The four types of precast reinforced concrete slab tenon and mortise installation structures shown include wall panel 1, as well as connection mechanism and auxiliary mechanism; The connecting mechanism is set on the outer wall of the wall panel 1. The connecting mechanism includes a tenon and mortise assembly and a locking assembly. The tenon and mortise assembly is set on the outer wall of the wall panel 1, and the locking assembly is set on the tenon and mortise assembly. The auxiliary mechanism is installed on the outer wall of the wall panel 1. The auxiliary mechanism includes an external support component and a reinforcing component. The external support component is installed on the tenon and mortise component, and the reinforcing component is installed on the outer wall of the wall panel 1.

[0020] like Figures 1-6 As shown, the tenon and mortise assembly includes a tenon plate 2 and a mortise groove 3. The tenon plate 2 is fixedly installed on the outer wall of the wall panel 1, and the mortise groove 3 is opened on the outer wall of the wall panel 1. The connection between the two wall panels 1 is completed by inserting the tenon plate 2 of one wall panel 1 into the mortise groove 3 of another wall panel 1.

[0021] like Figures 2-5 As shown, the locking assembly includes three mounting slots 4, three mounting bases 5, six first springs 6, six retaining seats 7, and six locking grooves 8. Each mounting slot 4 is formed on the outer wall of the tenon plate 2. The three mounting bases 5 are respectively fixedly installed inside the three mounting slots 4. The six first springs 6 are respectively fixedly installed on both sides of the outer wall of the three mounting bases 5. The six retaining seats 7 are respectively fixed to the other end of the six first springs 6. The six locking grooves 8 are respectively formed on both sides of the inner wall of the mortise 3. The six retaining seats 7 are all made of alloy material, and the outer surface of each of the six retaining seats 7 is provided with a chamfered surface. The corners of the mortise 3 are all provided with rounded corners. The rounded corners cooperate with the chamfered surfaces to lock the mortise 3. During the connection of the wall panel 1 via the tenon plate 2 and the mortise 3, the arc corner on the mortise 3 is continuously pressed by the beveled surface on the bracket 7, causing it to retract into the mounting groove 4 and compressing the first spring 6 as it retracts. After the tenon plate 2 is inserted into the mortise 3, the bracket 8 will align with the opening of the mounting groove 4, eliminating the pressure on the bracket 7. This releases the first spring 6, pushing the bracket 7 out and inserting it into the bracket 8. At this point, half of the bracket 7 is inside the bracket 8 and half is inside the mounting groove 4. This fixes the position of the two wall panels 1 after they are connected by the tenon and mortise assembly, thereby enhancing the connection strength.

[0022] like Figure 4As shown, the external support assembly includes a connecting groove 11, three second springs 12, and a top block 13. The connecting groove 11 is opened on the outer wall of the tenon plate 2. Each second spring 12 is fixedly installed inside the connecting groove 11. The top block 13 is fixedly installed on the other end of the three second springs 12. When the two wall panels 1 are connected, the inner wall of the mortise 3 of one wall panel 1 will press the top block 13 on the other wall panel 1, causing it to enter the connecting groove 11 and press the three second springs 12, so that the three second springs 12 are always in an energy storage state. When the connection between the two wall panels 1 is released through the reinforcement assembly due to incorrect installation, the three second springs 12 will be released at the moment of release and the top block 13 will quickly push out the connected wall panel 1, thereby assisting the staff in releasing the fixation of the locking assembly.

[0023] like Figure 5 As shown, the reinforcing component includes six reserved slots 9 and a filling port 10. The six reserved slots 9 are respectively opened inside the six slots 8, and the filling port 10 is opened on the outer wall of the wall panel 1. When it is necessary to release the fixing of the locking component, steel bars are simultaneously inserted into the six reserved slots 9 to push the card holder 7 out of the slot 8 and push it completely back into the installation slot 4, thereby releasing the fixing of the locking component. After the two wall panels 1 are connected and it is determined that they will not be released, cement grout is added into the groove 3 through the filling port 10 to fill the internal connection gap and enhance the connection strength.

[0024] The specific working process of this utility model is as follows: First, the initial connection of wall panels 1 is made by inserting the tenon 2 of one wall panel 1 into the mortise 3 of another wall panel 1. During this process, the retainer 7 on the tenon 2 is pressed by the rounded corner of the mortise 3, and its beveled surface guides the retainer 7 to overcome the elastic force of the first spring 6 and retract into the mounting groove 4. When the tenon 2 is fully inserted into the mortise 3, so that the opening of the mounting groove 4 is precisely aligned with the retainer 8, the retainer 7 loses external pressure, the first spring 6 quickly releases its elastic potential energy, and pops the retainer 7 out, so that half of it is embedded in the retainer 8 and half remains in the mounting groove 4, thereby automatically completing the mechanical locking between the two wall panels 1. At the same time, during the connection process, the inner wall of the mortise 3 will press the top block 13 of the outer support component, causing it to compress the second spring 12 and retract into the connecting groove 11, so that the second spring 12 is in a stored energy state. When it is necessary to disengage, a steel bar is simultaneously inserted into the reserved groove 9 of the reinforcing component to push the retainer 7 completely back into the mounting groove 4, thereby releasing the lock. At this point, the energy-storing second spring 12 will instantly push the connected wall panel 1 out through the top block 13, assisting in separation. If the connection is confirmed to be permanently reliable, cement grout can be injected into the mortise 3 through the injection port 10 on the wall panel 1 to fill all gaps and further enhance the integrity and strength of the connection.
