Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated wall technology, and in particular to a direct-clamp prefabricated wall system. Background Technology
[0002] Prefabricated walls refer to wall systems formed by assembling prefabricated wall components (such as concrete slabs, steel structure slabs, and wood structure slabs) on-site using mechanical hoisting and reliable connection technologies (such as sleeve grouting and bolt connections). Their core objective is to reduce on-site wet work and improve construction efficiency and quality.
[0003] Existing prefabricated wall systems have the following shortcomings in use:
[0004] Traditional wall decoration panels are mostly fixed as a whole. If a part is damaged, a large area of the wall needs to be removed, resulting in high maintenance costs and construction waste. At the same time, prefabricated walls rely on welding, bolting, or grouting for connection, which is complicated and inefficient. Utility Model Content
[0005] The purpose of this utility model is to solve the problems of traditional wall decoration panels, which are mostly fixed as a whole. When a part is damaged, a large area of the wall needs to be removed, resulting in high maintenance costs and construction waste. At the same time, prefabricated walls rely on welding, bolting, or grouting for connection, which is cumbersome and inefficient. Therefore, a direct-clamp prefabricated wall system is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A direct-clamp prefabricated wall system includes multiple clip-on integrated keels. Decorative panels are provided on both sides of two adjacent clip-on integrated keels. Insert strips are inserted at both ends of each clip-on integrated keel. An installation mechanism is provided between the clip-on integrated keel and the decorative panel. When the decorative panel is installed between two clip-on integrated keels, the installation mechanism can fix the decorative panel.
[0008] In one possible design, the mounting mechanism includes two back-mounted keels, which are L-shaped. One side of each back-mounted keel has two mounting holes for inserting bolts. Bolts are inserted into the mounting holes. Both sides of the decorative panel have threaded holes for use with the bolts. One end of the bolt is threaded into the threaded hole.
[0009] In one possible design, a locking block is welded to one side of the back-mounted keel, and one end of the back-mounted keel is engaged between the integrated card-type keel and the insert strip via the locking block.
[0010] In one possible design, rock wool is filled between the two said integrated card-type keels.
[0011] In one possible design, a sponge strip is placed in the gap between the back-mounted keel and the integrated card keel to improve stability.
[0012] In one possible design, the back-mounted keel and the card block are an integrated structure.
[0013] In this application, during use, first install the top and bottom keel at the installation location, then fix the integrated clip-on keel to the desired location. Fill the space between two adjacent integrated clip-on keels with rock wool, insert the insert strip (made of metal) into the integrated clip-on keel, then move the back-hanging keel to one side of the decorative panel, aligning the mounting holes of the back-hanging keel with the threaded holes of the decorative panel. Then remove the bolt, pass the bolt through the mounting hole and rotate it to connect the threads, ensuring the bolt is tightly against the back-hanging keel for fixation. Finally, place a sponge strip on one side of the integrated clip-on keel, and the decorative panel is secured into the integrated clip-on keel via the clips on the back-hanging keel. Between the sponge strip and the insert strip, the decorative panel can be fixed. After fixing, the sponge strip will be fixed to the back-hanging keel and the card-type integrated keel through a straight clip. Each panel can be disassembled and installed independently, which facilitates the replacement of metal composite decorative panels, reduces the content of later maintenance work, and reduces maintenance costs. The decorative panel is a metal composite decorative panel. The metal composite decorative panel has a very light weight, which can reduce the load on the building structure and improve the overall performance of the building. The specifications of the metal composite decorative panel are: length 2400 / 3000mm; width 600 / 1200mm. Then repeat the above operation to install multiple decorative panels.
[0014] The beneficial effects of this utility model are as follows:
[0015] In this utility model, the direct-clamp type prefabricated wall system allows each metal composite decorative panel to be disassembled and installed independently through direct-clamp assembly. When a decorative panel is partially damaged, only that panel needs to be disassembled and replaced, without the need to demolish a large area of the wall. This greatly reduces the workload of later maintenance, lowers maintenance costs, and also reduces the generation of construction waste, which is in line with the concept of green environmental protection.
[0016] In this utility model, the prefabricated wall system with a straight clip-on design fixes the decorative panel through an installation mechanism (back-hanging keel, bolts, etc.). During installation, the back-hanging keel is first fixed to the decorative panel with bolts, and then the decorative panel is inserted between the clip-on integrated keel and the insert strip through the clips of the back-hanging keel to complete the installation. There is no need for complicated welding, grouting and other processes. The operation is simple and quick, which greatly improves the construction efficiency and shortens the construction period.
[0017] In this invention, each metal composite decorative panel can be disassembled and installed independently through a direct-clamp assembly. When a certain decorative panel is partially damaged, only that panel needs to be disassembled and replaced, without the need to demolish a large area of the wall, which greatly reduces the workload of later maintenance and lowers maintenance costs.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example
[0024] Reference Figure 1-4 A direct-clamp prefabricated wall system, used in the field of prefabricated walls, includes: multiple clip-on integrated keels 3, decorative panels 1, insert strips 4, installation mechanisms, rock wool 2, and sponge strips 5. Decorative panels 1 are provided on both sides of every two adjacent clip-on integrated keels 3. The decorative panels 1 are metal composite decorative panels with extremely light weight, which can reduce the load on the building structure and improve the overall performance of the building. Their specifications are 2400 / 3000mm in length and 600 / 1200mm in width.
[0025] Both ends of the integrated card-type keel 3 are fitted with inserts 4, which are made of metal and are used to cooperate with the integrated card-type keel 3 to provide a structural basis for the snap-fit connection of the back-hanging keel 6.
[0026] The mounting mechanism is used to secure the decorative panel 1 when it is installed between two integrated clip-on keels 3. The mounting mechanism includes two back-hanging keels 6, which are L-shaped. One side of each back-hanging keel 6 has two mounting holes for bolts to pass through. Both sides of the decorative panel 1 have threaded holes for bolts to mate with. One end of the bolt is threaded into the threaded hole, thereby achieving a fixed connection between the back-hanging keel 6 and the decorative panel 1.
[0027] A locking block 7 is welded to one side of the back-hanging keel 6. The back-hanging keel 6 and the locking block 7 are an integral structure. This integral structure enhances the connection strength between the back-hanging keel 6 and the locking block 7, and improves the stability of the entire installation mechanism. One end of the back-hanging keel 6 is locked between the card-type integrated keel 3 and the insert strip 4 through the locking block 7, further fixing the decorative panel 1 between the two card-type integrated keels 3. Example
[0028] refer to Figure 1-4 Improvements based on Example 1:
[0029] Rock wool 2 is filled between the two integrated keel 3. Rock wool 2 has good sound insulation and heat insulation performance, which can effectively improve the sound insulation and heat insulation effect of the wall and create a quieter and more comfortable indoor environment.
[0030] A sponge strip 5 is placed in the gap between the back-mounted keel 6 and the card-type integrated keel 3. The sponge strip 5 can fill the gap, reduce the shaking of the decorative panel 1 caused by vibration or external force, and improve the stability of the wall.
