Description

Technical Field

[0001] This utility model relates to the field of keel connection technology, and in particular to an ultra-heavy-duty aluminum alloy keel under-mount connection system. Background Technology

[0002] According to market research and surveys, the ultra-heavy-duty ceiling joist systems currently used in the market, capable of supporting more than 1000 kg / m², have the following shortcomings in structural design, installation, maintenance, and use:

[0003] 1. Some load-bearing ceiling structures used in the market have non-standard and unreasonable structural designs that do not fully consider the premise of safe use. The keel materials are lightweight and the wall thickness is thin, which brings certain hidden dangers to the safety, quality and subsequent use of the project.

[0004] 2. Most of the connections used in the market are made of steel. The processing and installation of the connectors are complicated and require shearing, punching, bending, and surface processing, which prolongs the manufacturing and installation cycle, increases the unit price of the products, and makes the ceiling very heavy, which affects the load-bearing capacity of the factory design and also affects the cost of the factory.

[0005] 3. The usage method is relatively simple and does not fully consider the addition or removal of facilities and equipment during the use of cleanrooms. When modifications are needed, the dismantling and installation are inconvenient and difficult to complete.

[0006] 4. Installation and daily maintenance are inconvenient. Cleanroom installation is usually in the final stage of the entire project and is carried out simultaneously with the factory's facilities and equipment. Therefore, it requires a short construction period, fast speed, and quick and easy dismantling and installation during daily use.

[0007] Therefore, designing a simple and easy-to-install ultra-heavy-duty aluminum alloy keel under-mount connection system has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] In view of the shortcomings or deficiencies of the prior art, the technical problem to be solved by this utility model is to provide an ultra-heavy-duty aluminum alloy keel under-mount connection system.

[0009] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0010] A heavy-duty aluminum alloy keel under-mount connection system includes:

[0011] The keel body is configured as a closed square structure;

[0012] The upper part of the keel body is provided with an upper groove, which is connected to the horizontal adjustment structure through a connector;

[0013] The bottom of the keel body is provided with a lower groove for connecting parts to be engaged, and the two sides of the upper groove are provided with slot structures for engaging support parts.

[0014] Furthermore, the upper groove and / or the lower groove are provided with an anti-slip structure.

[0015] Furthermore, one end of the support member is bent and inserted into the slot structure, and the other end of the support member is set close to one side of the keel body.

[0016] Furthermore, the bottom of the support member is bent at 90° and adjacent support members are spliced ​​together to form a continuous groove for placing ceiling panels.

[0017] Furthermore, the outer side of the slot structure is provided with an arc-shaped opening.

[0018] Furthermore, the connector uses a T-bolt, and a flange lock nut is fitted onto the T-bolt.

[0019] Furthermore, the keel body is made of aluminum alloy and has an oxide coating on its surface.

[0020] Compared with the prior art, this application has the following technical effects:

[0021] In this application, both the upper and lower slots contain placement screws, which, when connected to anti-reverse nuts, allow for easy assembly of multiple keel frames on the ground using only simple tools. Installation can then be completed by lifting the frames with a lift, simplifying installation and maintenance. Maintenance only requires removing relevant parts for disassembly, replacement, or repair. The cutting and assembly process is straightforward; materials are extruded and cut, undergoing preliminary processing in the factory before on-site assembly. This results in a short construction period and relatively low skill requirements for workers, thus reducing labor and processing costs. Furthermore, the keel body is made of high-strength aluminum alloy, which enhances the strength of the keel connectors, ensuring safety and convenience during installation and use.
