Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a corner connection device for installing ALC strip panels on the exterior walls of high-rise buildings. Background Technology

[0002] ALC panels are short for autoclaved lightweight aerated concrete partition walls. They have advantages such as being lightweight, fireproof, soundproof, environmentally friendly, economical, and easy to install. They can be used as exterior wall panels. After the ALC panels are installed, sealing strips are used to seal the gaps between them. At the corners, the sealing strips are fixedly connected by a corner connecting device to improve the sealing effect.

[0003] Existing corner connection devices mainly use L-shaped bent connecting blocks as the main body. The two ends of the connecting block are connected to the connecting ends of two sealing strips by bolts or welding to complete the corner connection. However, the connection between the connecting block and the sealing strip is directly exposed, which is prone to corrosion and rust over time, causing rainwater to seep in. Therefore, we need to propose a corner connection device for installing ALC strip panels on the exterior walls of high-rise buildings. Utility Model Content

[0007] The positioning mechanism includes a lead screw, the outer surface of which is provided with two rotating threads of the same length but opposite direction. A ball slider is sleeved on the outer side of the rotating threads. A connecting rod is fixedly connected to one side of the ball slider, and a positioning plate is fixedly connected to one end of the connecting rod.

[0008] Both ends of the connecting block are fitted with sealing sleeves on the outer side. A sliding block is fixedly connected to one end of the sealing sleeve, and the sliding block is slidably connected to the sliding groove. Bolts are threaded to both sides of the other end of the sealing sleeve.

[0009] Preferably, the two end faces of the connecting block are respectively attached to the two sealing strips, and the sealing sleeve covers the outside of the connection between the connecting block and the sealing strips.

[0010] Preferably, the sliding block is embedded inside the sliding groove and forms a sliding limiting structure with the sliding groove.

[0011] Preferably, one end of the bolt passes through the sealing sleeve, and the other end of the bolt is threadedly fixed to the sealing strip.

[0012] Preferably, the lead screw is movably connected to the connecting block, and the top end of the lead screw passes through the connecting block.

[0013] Preferably, the connecting rod passes through the inner side of the connecting block and is slidably connected to the connecting block.

[0014] Preferably, the two positioning plates are symmetrically arranged, and one side of the positioning plate is attached to the inner surface of the ALC plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a connecting block placed at the corner where two ALC plates meet, so that both ends of the connecting block are respectively attached to the two sealing strips. Then, the sealing sleeve is slid outward, and the sliding block and sliding groove limit the movement of the sealing sleeve to ensure the stability of the movement of the sealing sleeve.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A corner connection device for installing ALC strip panels on the exterior wall of a high-rise building includes: two symmetrically arranged ALC panels 1, with sealing strips 2 fixedly connected to the opposite sides of the two ALC panels 1; a connecting block 3 is centrally located on the opposite sides of the two sealing strips 2, with a pair of sliding grooves 4 on the outer surfaces of both ends of the connecting block 3, and a positioning mechanism 5 centrally located on the inner side of the connecting block 3. The connecting block 3 is placed at the corner of the connection between the two ALC panels 1, so that both ends of the connecting block 3 are respectively attached to the two sealing strips 2, and then a sealing sleeve 6 is slid outward. The sliding block 7 cooperates with the sliding grooves 4 to limit the movement of the sealing sleeve 6, ensuring the stability of the movement of the sealing sleeve 6, so that the sealing sleeve 6 is located on the outer side of the connection between the connecting block 3 and the sealing strip 2, and finally fixed by bolts 8. The connection device with a sealing structure can seal the corner of the sealing component and reduce the problem of rainwater infiltration.

[0026] The positioning mechanism 5 includes a lead screw 9. The outer surface of the lead screw 9 has two rotating threads 10 of the same length but opposite direction. A ball slider 11 is sleeved on the outer side of the rotating threads 10. A connecting rod 12 is fixedly connected to one side of the ball slider 11. A positioning plate 13 is fixedly connected to one end of the connecting rod 12. By rotating the lead screw 9, the two rotating threads 10 are driven, causing the ball slider 11 to drive the connecting rod 12 and the positioning plate 13 to move synchronously in opposite directions, thereby realizing the rapid positioning of the connecting block 3 and the ALC plate 1. The sealing sleeve 6 slides along the sliding groove 4 through the sliding block 7 to the joint between the connecting block 3 and the sealing strip 2, and is then fixed by bolts 8, forming a sealing barrier to the external environment and effectively preventing rainwater penetration.

[0027] Both ends of the connecting block 3 are fitted with sealing sleeves 6 on the outer side. One end of the sealing sleeve 6 is fixedly connected to a sliding block 7, which is slidably connected to the sliding groove 4. The other end of the sealing sleeve 6 is threaded with bolts 8 on both sides. By setting a positioning mechanism 5, the lead screw 9 cooperates with two rotating threads 10 to make the two ball sliders 11 drive the two connecting rods 12 to move synchronously in opposite directions, so that the two positioning plates 13 are respectively attached to the inner surfaces of the two ALC plates 1, thus completing the installation of the connecting block 3. Conversely, the connecting block 3 can be disassembled. By setting a pair of positioning mechanisms 5 that can be adjusted synchronously, the installation and disassembly of the connecting parts can be carried out quickly, improving the convenience of using the connecting parts.

[0028] The two end faces of the connecting block 3 are respectively attached to the two sealing strips 2. The sealing sleeve 6 covers the outside of the connection between the connecting block 3 and the sealing strip 2. The sealing sleeve 6 completely wraps the joint surface between the connecting block 3 and the sealing strip 2. The sealing performance is further enhanced by elastic material or waterproof coating to avoid corrosion and leakage caused by long-term exposure.

[0029] The sliding block 7 is embedded inside the sliding groove 4 and forms a sliding limiting structure with the sliding groove 4. The groove depth of the sliding groove 4 matches the size of the sliding block 7 to ensure that the sealing sleeve 6 remains stable during movement, avoids displacement or falling off, and thus ensures the accuracy of the sealing coverage.

[0030] One end of the bolt 8 passes through the sealing sleeve 6, and the other end of the bolt 8 is threadedly fixed to the sealing strip 2. The bolt 8 is made of rust-proof material, and a sealing gasket is provided at its threaded connection to further enhance the waterproof performance of the connection and facilitate disassembly and maintenance.

[0031] The lead screw 9 is internally and movably connected to the connecting block 3, and the top end of the lead screw 9 passes through the connecting block 3. The top end of the lead screw 9 is provided with a rotating handle or a hexagonal groove, which makes it easy to drive its rotation with a tool to achieve synchronous adjustment of the positioning plate 13 and simplify the installation process.

[0032] The connecting rod 12 passes through the inner side of the connecting block 3 and is slidably connected to the connecting block 3. A guide groove or lubrication layer is provided between the connecting rod 12 and the connecting block 3 to reduce frictional resistance, ensure the smooth movement of the positioning plate 13, and improve adjustment efficiency.

[0033] Two positioning plates 13 are symmetrically arranged, and one side of the positioning plate 13 is attached to the inner surface of the ALC plate 1. The positioning plate 13 is made of wear-resistant rubber or elastic metal material, and its contact surface is provided with anti-slip texture to enhance the friction with the ALC plate 1 and prevent loosening after installation.

[0034] Working principle: When using this utility model, the connecting block 3 is placed at the corner where the two ALC plates 1 are connected, so that both ends of the connecting block 3 are respectively attached to the two sealing strips 2. Then, the top of the screw 9 is rotated, so that the screw 9 rotates inside the connecting block 3. The screw 9 cooperates with the two rotating threads 10, so that the two ball sliders 11 drive the two connecting rods 12 to move synchronously in opposite directions, so that the two positioning plates 13 are respectively attached to the inner surfaces of the two ALC plates 1, completing the installation of the connecting block 3. Then, the sealing sleeve 6 is slid outward. The sliding block 7 cooperates with the sliding groove 4 to limit the movement of the sealing sleeve 6, ensuring the stability of the movement of the sealing sleeve 6, so that the sealing sleeve 6 is located on the outer side of the connection between the connecting block 3 and the sealing strip 2. Finally, the sealing sleeve 6 is fixedly connected to the sealing strip 2 by the bolt 8. The sealing sleeve 6 seals and protects the connection between the connecting block 3 and the sealing strip 2, reducing the leakage problem.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
