Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of installation and connection devices, specifically a quick installation and connection device for prefabricated wall panels. Background Technology
[0002] Prefabricated walls refer to building walls constructed using traditional on-site construction methods. These walls are manufactured in a factory, transported to the construction site, and then installed by splicing. Prefabricated walls require installation and connection devices during on-site installation.
[0003] A search revealed a patent, CN214994879U, which discloses a prefabricated wall panel connector. The connector includes bolts that pass through a first fixing block and a second fixing block. The first fixing block is fixedly installed on one side of a first connector. The first connector has a slot for connection and is fixedly installed on one side of a first wall panel. The second fixing block is fixedly installed on a second connector, which is also fixedly installed on one side of a second wall panel. A slide rail is fixedly installed inside the second connector, and a slider is slidably installed on the slide rail. Self-tapping screws are used to install the first connector onto one side of the first wall panel and the second connector onto one side of the second wall panel through mounting holes. Moving the second connector inserts a rod into the slot, moving the connecting rod causes the slider to move downwards along the slide rail. A positioning pin is then used to fix the connecting rod, completing the connection and fixation of the first and second wall panels. This design is convenient to construct, easy to disassemble, and saves time and effort.
[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:
[0005] The aforementioned comparative document describes the installation and connection of two wall panels by bolting two protruding first fixing blocks. However, in reality, the first fixing blocks in the aforementioned comparative document protrude from the side of the wall panel. Since the wall panel needs to be painted or decorated after installation, the protruding first fixing blocks will affect the later painting or decoration, reducing the practicality of the installation and connection device. Therefore, there is an urgent need in the art to improve the installation and connection device to solve the defects of the prior art. Utility Model Content

[0027] 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.
[0028] Please see Figures 1-5 The prefabricated wall panel quick installation connection device includes a connecting frame 1 and a connecting groove 3 opened on opposite sides of the wall panel body 2 and adapted to the connecting frame 1. A pre-embedded connecting cylinder 4 with one end adapted to the inner side wall of the connecting groove 3 is pre-embedded in the wall panel body 2. Through openings 6 adapted to the pre-embedded connecting cylinder 4 are opened through opposite sides of the connecting frame 1. A connecting bolt 5 with one end threaded to the end of the pre-embedded connecting cylinder 4 is inserted in the through opening 6.
[0029] Specifically, the pre-embedded connecting cylinder 4 is embedded inside the prefabricated wall panel body 2 during the prefabrication process. Each wall panel body 2 has at least two connecting grooves 3 on opposite sides. First, one wall panel body 2 is erected and fixed in position. The connecting bracket 1 is inserted into the connecting groove 3, and the through-hole 6 is aligned with the position of the pre-embedded connecting cylinder 4. One end of the connecting bolt 5 is inserted through the through-hole 6 and its end is threaded to the pre-embedded connecting cylinder 4. Then, the second wall panel body 2 is erected and its side connecting groove 3 is snapped onto the side of the pre-embedded connecting cylinder 4. The connecting bolt 5 is again threaded to the pre-embedded connecting cylinder 4 through the through-hole 6. The two connecting bolts 5 are then tightened to complete the installation connection of the two wall panel bodies 2. The installation structure is simple and the operation is convenient. When the surface of the wall panel body 2 is painted later, cement or other fillers are used to fill the inside of the connecting bracket 1 to improve the practicality of the prefabricated wall panel installation connection device. If the area of the wall panel body 2 is small, two or more wall panel bodies 2 can be connected on the ground through the connecting bracket 1 and the connecting bolt 5 before assembly.
[0030] As a technical optimization of this utility model, a pre-embedded connecting cylinder 4 is fixedly connected to a pre-embedded platform 7 at one end. The pre-embedded platform 7 is pre-embedded in the wall panel body 2. A pre-embedded steel plate 8 is fixedly connected to the end of the pre-embedded platform 7 away from the pre-embedded connecting cylinder 4. The pre-embedded steel plate 8 is pre-embedded in the wall panel body 2. Several pre-embedded reinforcing bars 9 are fixedly connected to the side of the pre-embedded steel plate 8 away from the pre-embedded platform 7. One end of the pre-embedded reinforcing bars 9 is hook-shaped and welded to the reinforcement inside the wall panel body 2.
[0031] Specifically, when the wall panel body 2 is prefabricated, the pre-embedded connecting cylinder 4 is positioned in the connecting groove 3, and the pre-embedded reinforcing steel bar 9 is welded to the internal reinforcement of the wall panel body 2. The connection strength of the pre-embedded connecting cylinder 4 is improved by the pre-embedded platform 7, the pre-embedded steel plate 8 and the pre-embedded reinforcing steel bar 9, thereby improving the connection strength of the adjacent wall panel bodies 2 after installation and connection.
[0032] As a technical optimization of this utility model, the connecting frame 1 is provided with a first sealing plate 10 and a second sealing plate 11 on opposite sides, one side of which is flush with the side of the wall panel body 2. The first sealing plate 10 is fixedly connected to a connecting threaded rod 12 that penetrates the second sealing plate 11 on the side close to the second sealing plate 11. The second sealing plate 11 is provided with a countersunk hole 13 that is adapted to the connecting threaded rod 12 on the side away from the first sealing plate 10. The side of the connecting threaded rod 12 located in the countersunk hole 13 is threaded with a locking nut 14. A grouting hole 19 is provided through the second sealing plate 11.
[0033] Specifically, after the wall panel body 2 is installed and connected, the first sealing plate 10 is tightly attached to one side of the connecting frame 1, and the second sealing plate 11 is tightly attached to the other opposite side of the connecting frame 1. The connecting threaded rod 12 passes through the second sealing plate 11, and the locking nut 14 is threadedly connected to the side of the connecting threaded rod 12. The locking nut 14 is located in the countersunk hole 13. The locking nut 14 is locked, and grout is injected into the connecting frame 1 through the grouting hole 19 to further improve the stability of the wall panel body 2 after installation and connection, and does not hinder the surface painting of the wall panel body 2. When painting the wall panel body 2, the first sealing plate 10 and the second sealing plate 11 are rust-proofed.
[0034] As a technical optimization of this utility model, it also includes an embedding groove 16 opened on the opposite side of the wall panel body 2. An elastic sealing strip 15 is embedded in the embedding groove 16. An elastic protruding strip 17 is provided on the opposite side of the sealing strip 15. A snap-fit groove 18 adapted to the protruding strip 17 is opened on the opposite side wall of the embedding groove 16.
[0035] Specifically, before installing and connecting two adjacent wall panel bodies 2, an elastic sealing strip 15 is embedded in the embedding groove 16, and an elastic protruding strip 17 is snapped into the snap-fit groove 18 to limit the sealing strip 15. When not squeezed, one side of the sealing strip 15 extends beyond the side of the wall panel body 2. After the two wall panel bodies 2 are installed and connected, the two sealing strips 15 are tightly pressed together, and the two wall panel bodies 2 are tightly attached to each other. There are no gaps between the sealing strips 15 of the two wall panel bodies 2, thereby improving the sound insulation effect after the wall panel bodies 2 are installed and connected.
