Description

TECHNICAL FIELD

[0001] The utility model relates to prefabricated building technical field, concretely relates to a tongue and groove type steel frame light outer hanging wallboard system. BACKGROUND

[0002] In the petrochemical industry, chemical industry, pharmaceutical industry, textile industry and other industries, these industries often involve flammable and explosive substances in the production process, and once an explosion occurs, the consequences are unpredictable. Therefore, the setting of the explosion vent wall becomes a key measure to ensure safety in production. For example, in the reaction workshop and storage tank area of a chemical plant, the explosion vent wall can quickly release pressure through the pre-set weak link when an explosion occurs, reduce the damage to the main structure, and effectively prevent the spread of explosion shock waves and debris.

[0042] Specific implementation steps

[0043] 1. Prefabricated panel wall: according to the column distance and wall height of the main structure, the whole wall is divided into several panel walls, and the size specifications of the panel walls are unified as much as possible to improve the processing efficiency.

[0044] According to the deepening drawing, the hoisting hole is first punched on the main frame, and the hoisting hole is arranged at a position 1 / 6 of the length of the steel frame from the two ends of the steel frame. The sealing plate 15 is welded at the connection between the bottom main frame 11, the top main frame 12 and the auxiliary frame 13 and the reinforcing rib 16.

[0045] The bottom main frame 11, the top main frame 12 and the reinforcing rib 16 are welded to form the main structural frame of the panel wall.

[0046] The reinforcing mesh 14 is laid and welded and fixed with the main structural frame.

[0047] The structural frame of the panel wall is placed on the mold, and since the four sides of the steel frame itself form a side mold, it is not necessary to support the mold again. The foam concrete 17 with a density of 400 kg / m³ is poured, and the fiber anti-cracking mesh can be embedded on both sides of the panel wall.

[0048] After normal maintenance and reaching the hoisting and transportation conditions, the panel wall is loaded and transported to the construction site. Before loading, the air-tight strip 8 can be installed on the steel frame to improve the installation efficiency on site.

[0049] 2. On-site installation: after the on-site line positioning, the composite wall panel is installed in sequence from bottom to top. The composite wall panel is welded to the main structure through the bottom main frame 11 and the top main frame 12.

[0050] Considering the interlayer displacement of the main structure, the deformation ability of the sealing material and the installation error, etc., the joint between the outer hanging plate wall needs to be reserved 15mm-35mm.

[0051] At the joint, the fireproof sealing material 7 is filled in the inner side of the air-tight strip 8 fixed on the plate wall in advance, and the outer side is inserted into the backing material 4 and sealed with the sealant 3.

[0052] After the sealant 3 reaches the strength, the light aggregate concrete 2 is used to fill the groove.
