Description

Technical Field

[0001] This application relates to the technical field of curtain walls, and in particular to a prefabricated curtain wall structure for building exterior walls. Background Technology

[0002] Currently, prefabricated curtain walls refer to a non-load-bearing exterior wall system in which curtain wall panels such as glass and aluminum plates, supporting frames, insulation layers, sealing systems, and connectors are assembled into complete unit panels in a factory, transported to the construction site, and then installed as a whole onto the keel frame of the building's exterior wall using hoisting equipment.

[0003] After the hoisting equipment lifts the unit panels to the designated construction location, the construction workers need to work together to fine-tune the position of the unit panels to ensure precise alignment with the keel frame. Finally, the unit panels are fixed to the outside of the keel frame using fasteners. However, during the fixing process, the unit panels are prone to displacement due to wind loads or improper operation by the construction workers. If the displacement exceeds the acceptable range, the unit panels will not be able to be installed smoothly on the keel frame, thus increasing the construction difficulty and making it difficult to ensure the stability of the unit panels during the installation and fixing process. Utility Model Content

[0004] This application provides a prefabricated curtain wall structure for building exterior walls, which can ensure the stability of unit panels during the installation and fixing process, and ensure that the unit panels and the keel frame can be accurately aligned, thereby facilitating construction.

[0015] The present application will be further described in detail below with reference to the accompanying drawings.

[0016] This application discloses a prefabricated curtain wall structure for building exterior walls.

[0017] Reference Figure 1 , Figure 2 The prefabricated curtain wall structure for building exterior walls includes a frame 1 for fixed installation on the building exterior wall, and unit panels 2 for installation on the exterior facade of the frame 1. The frame 1 has insertion slots 10 located below the unit panels 2. The length of the insertion slots 10 extends along the width of the unit panels 2. Three support members 3 are slidably installed within the insertion slots 10. The unit panels 2 are mounted on top of the support members 3, which support the unit panels 2, thereby ensuring the stability of the unit panels 2.

[0018] like Figure 3 , Figure 4As shown, a first fastener 30 is fixedly installed on the support member 3. The first fastener 30 is a fastening bolt and is vertically installed. A sliding groove 100 communicating with the insertion groove 10 is passed through the inner side wall of the keel frame 1. The first fastener 30 is slidably installed in the sliding groove 100 along with the support member 3, and the top of the first fastener 30 protrudes from the top opening of the sliding groove 100. A fastening nut is threadedly connected to the top of the first fastener 30. The fastening nut tightens and fixes the first fastener 30 and the support member 3 to the keel frame 1.

[0019] like Figure 3 , Figure 4 As shown, the bottom of the unit plate 2 is provided with positioning grooves 20 corresponding to the support members 3, and the ends of the support members 3 are respectively inserted and fixed in their respective positioning grooves 20. Through the mutual insertion and cooperation between the support members 3 and the positioning grooves 20, the displacement of the unit plate 2 along its own width direction can be effectively prevented.

[0020] like Figure 4 , Figure 5 as well as Figure 6 As shown, a limiting frame 4 is fixedly installed on the side wall of the unit panel 2 facing the keel frame 1, and is inserted into the inner side wall of the keel frame 1. The outer side wall of the limiting frame 4 is in contact with the inner side wall of the keel frame 1. Multiple sets of positioning components 5 are arranged circumferentially around the limiting frame 4 on the inner side wall of the keel frame 1. The limiting frame 4 is provided with positioning holes 40 that are one-to-one with the positioning components 5. The positioning components 5 are interlocked with their respective positioning holes 40, and the interlocking of the two restricts the unit panel 2 from detaching from the outer facade of the keel frame 1.

[0021] like Figure 4 , Figure 5 as well as Figure 6 As shown, the positioning component 5 includes a positioning post 50 slidably disposed on the keel frame 1. The sliding direction of the positioning post 50 is perpendicular to the insertion direction of the limiting frame 4 into the keel frame 1. The tail of the positioning post 50 is limited within the keel frame 1, and the end of the positioning post 50 is used to insert into its respective corresponding positioning hole 40. The positioning component 5 also includes a positioning spring 51 for pushing the end of the positioning post 50 into the positioning hole 40. The positioning spring 51 extends and retracts along the sliding direction of the positioning post 50, and is limited within the keel frame 1. One end of the positioning spring 51 is fixedly connected to the positioning post 50, and the other end of the positioning spring 51 is fixed within the keel frame 1.

[0022] like Figure 4 , Figure 5As shown, the end of the positioning post 50 is provided with a guide ramp 52 located outside the keel frame 1. The guide ramp 52 is located on the side wall of the positioning post 50 facing the insertion direction of the limiting frame 4. The guide ramp 52 is used to guide the limiting frame 4 to smoothly pass over the positioning post 50. As the limiting frame 4 gradually pushes the positioning post 50 into the keel frame 1, the positioning spring 51 will be gradually compressed and store potential energy. When the positioning hole 40 moves to be directly opposite the positioning post 50, the positioning post 50 will be inserted into the positioning hole 40 under the elastic force of the positioning spring 51. Through the mutual insertion and cooperation of the positioning post 50 and the positioning hole 40, the unit panel 2 can be effectively restricted from detaching from the keel frame 1. At the same time, it also ensures the precise alignment of the unit panel 2 with the keel frame 1, ensuring the stability of the unit panel 2 during the installation and fixing process, thereby facilitating subsequent construction.

[0023] like Figure 2 , Figure 3 As shown, a limiting groove 11 is provided on the outer wall of the keel frame 1 along the vertical direction, and the length of the limiting groove 11 extends along the length direction of the keel frame 1. The limiting groove 11 is symmetrically arranged on the left and right sides of the unit plate 2, and a side cover plate 6 is inserted into the limiting groove 11 along the horizontal direction. Two sets of plug-in strips 21 are provided on the outer surface of the unit plate 2, and the two sets of plug-in strips 21 are symmetrically arranged on the left and right sides of the unit plate 2, and the cross-section of the plug-in strips 21 is approximately T-shaped. The plug-in strips 21 in the same group are arranged sequentially at intervals along the length direction of the unit plate 2, and the length of the plug-in strips 21 extends along the width direction of the unit plate 2. The side cover plate 6 is provided with a side slot 60 that is inserted and fixed to the plug-in strips 21, and the shape of the side slot 60 is adapted to the shape of the plug-in strip 21. The side cover plates 6 located on both sides of the unit plate 2 can further restrict the unit plate 2 from detaching from the keel frame 1, and further improve the stability and reliability of the unit plate 2.

[0024] like Figure 2 , Figure 3 As shown, multiple second fasteners 61 are installed on the outer surface of the side cover plate 6. The second fasteners 61 are fastening bolts, which tighten and fix the unit plate 2 to the outer surface of the keel frame 1.

[0025] like Figure 2 , Figure 3 As shown, the bottom of the keel frame 1 is provided with a bottom cover plate 7 located between the side cover plates 6. The bottom cover plate 7 covers the outside of the support member 3. The bottom cover plate 7 covers the support member 3 and the insertion groove 10, thereby further enhancing the sealing protection of the insertion groove 10, reducing the probability of external rainwater entering the interior of the keel frame 1 through the insertion groove 10, and improving the waterproof level.

[0026] like Figure 2 , Figure 3As shown, four positioning plates 70 are fixedly installed at the bottom of the bottom cover plate 7, and the positioning plates 70 are arranged at intervals along the length of the bottom cover plate 7. The positioning plates 70 are inserted into the keel frame 1 from top to bottom. Four third fasteners 12, each corresponding to a positioning plate 70, are provided on the outer surface of the keel frame 1. The third fasteners 12 are bolts, which tighten and fix the positioning plates 70 to the keel frame 1, thereby limiting and fixing the bottom cover plate 7.

[0027] like Figure 2 , Figure 3 As shown, a side insert 62 is fixedly installed on the side wall of the side cover plate 6 facing the bottom cover plate 7. The cross-section of the side insert 62 is also T-shaped. The bottom cover plate 7 is provided with a connecting groove 71 that is inserted and fixed to the corresponding side insert 62. The shape of the connecting groove 71 is adapted to the shape of the side insert 62. Through the mutual insertion and cooperation of the side insert 62 and the connecting groove 71, the limiting and fixing effect of the side cover plate 6 on the unit plate 2 can be further improved, and the connection reliability between the two can be enhanced.

[0028] The implementation principle is as follows: The mutual insertion and engagement of the support member 3 and the positioning groove 20 effectively prevents the unit panel 2 from shifting along its width. The positioning component 5 and its corresponding positioning hole 40 mutually insert and engage, further restricting the unit panel 2 from detaching from the outer facade of the keel frame 1. This also ensures precise alignment of the unit panel 2 with the keel frame 1, guaranteeing the stability of the unit panel 2 during installation and fixing, thus facilitating subsequent construction. The side cover plates 6 located on both sides of the unit panel 2 further restrict the unit panel 2 from detaching from the keel frame 1, further enhancing the stability and reliability of the unit panel 2. The mutual insertion and engagement of the side insert 62 and the connecting groove 71 further improves the limiting and fixing effect of the side cover plate 6 on the unit panel 2, enhancing the connection reliability between the two.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
