Description

Technical Field

[0001] This invention relates to the field of building partition technology, and in particular to a suspended high partition system and its construction method. Background Technology

[0002] In the construction industry, partition walls are often required on rooftops to achieve spatial division and functional zoning. The main structure and roof steel structure are susceptible to deformation due to environmental and temperature changes. Since traditional high partition walls are directly fixed to the main structure, with the upper part fixed to the steel truss, the wall itself is affected by the combined deformation of the main structure and the roof truss, leading to cracks or even damage. This shortens the lifespan of the partition wall, adversely affecting the safety and stability of the building and the overall structural stability. Therefore, there is an urgent need to design a partition wall structure that can better adapt to the deformation of the main structure and roof structure to ensure the stability of the overall structure. Summary of the Invention

[0021] The beneficial effects of this invention are reflected in:

[0022] 1. This invention provides a suspended high partition wall system and its construction method, which uses clamps to connect to the roof steel structure, fixing the high partition wall to the roof steel structure in a suspended manner. This suspension method allows the high partition wall to move freely during the deformation of the main structure and the roof steel structure, thereby avoiding the impact of displacement or deformation on the overall structure. Compared with traditional fixing methods, the suspended high partition wall of this invention can better adapt to the deformation of the main structure and the roof steel structure, thus ensuring the stability and safety of the partition wall. At the same time, the suspension method can also reduce the impact on the main structure and improve the overall structural performance of the building.

[0023] 2. The present invention provides a suspended high partition wall system and its construction method. A horizontal expansion joint structure is set between the light steel keel partition wall and the concrete structural beam, which provides a certain vertical movement space for the light steel keel partition wall, so that the deformation between the light steel keel partition wall and the concrete structural beam is consistent. A vertical expansion joint structure is also set in the light steel keel partition wall, which provides a certain lateral movement space. This setting allows the light steel keel partition wall to have a certain displacement adjustment space without affecting the wall structure.

[0024] 3. The present invention provides a suspended high partition wall system and its construction method. The fixing components are connected to the steel truss using clamps. The use of clamps not only solves the problem of connecting the square steel keel frame to the steel truss, but also avoids the deformation caused by traditional welding methods after the steel truss is unloaded. Traditional high partition walls are often fixed by welding, but the welding process requires heating, which can easily cause deformation of the steel truss, thereby affecting the stability and aesthetics of the roof steel structure. The clamps use a locking connection, which does not require direct welding, thus avoiding such problems.

[0025] 4. The suspended high partition wall system and its construction method provided by the present invention use a square steel keel frame as the skeleton material of the light steel keel partition wall, which is the source of the stability and support capacity of the light steel keel partition wall; the square steel keel frame uses lightweight and sturdy steel pipe material, which has the characteristics of being lightweight and durable; the excellent toughness and strength of the square steel keel frame also ensures the stability of the high partition wall during transportation, installation and use.

The main objects and other advantages of the invention may be realized and obtained by means of the methods particularly pointed out in the description. Attached Figure Description
