Problems solved by technology
[0002] In the construction of steel structure industrial plants, there must be fire compartments. Common fire compartments generally use firewalls, fire shutter doors, independent water curtains, automatic sprinkler devices, fire monitors, etc. Firewall panels are the most commonly used fire compartments. The individual wall panels are fixed on the lightweight keel to form an overall firewall, but after the putty is applied, the fire panels often crack at the joints due to the vibration of large machinery in the factory building

Embodiment Construction
[0027] This example is a method for anti-seismic and anti-cracking of fireproof gypsum wallboard joints, including the following steps:
[0028] S1: The main keel 2 is fixed on the main structure 3 by welding, such as figure 1 As shown, the main keel 2 is welded and fixed around the interior of the main structure, and a main keel is welded at the center of the two opposite sides of the main structure 3, and the main keel is parallel to the length direction of the fireproof gypsum board 5;
[0029] S2: Fixedly connect the secondary keel 1 to the main keel 2. The secondary keel 1 and the main keel 2 can be connected by mechanical connection methods such as plugging and screw connection. The secondary keel 1 and the main keel 2 are connected to form a keel frame, and the keel frame and the main structure The welding is firm;
[0030] S3: if figure 2 As shown, the fireproof gypsum board 5 is fixed on the keel frame. The thickness, refractory material content and strength of the...

The invention provides a method for seismic cracking prevention of joints of a fireproof gypsum wallboard, and belongs to the technical field of construction. The method includes the following steps that 1, a main keel is fixed on a main structure; 2, a secondary keel and the main keel are connected to form a keel skeleton; 3, fireproof boards are fixed on the keel skeleton; 4, the fireproof boards are spliced; and 5, the joints of the fireproof boards are processed. The method has the beneficial effects that construction is simple, forming is beautiful, integrity is good after forming, cracking is greatly reduced, the construction speed is increased, and an effective guarantee is provided for the construction quality of the large area firewall.
Description
technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an anti-seismic and anti-cracking method for joints of fireproof gypsum wallboards. Background technique [0002] In the construction of steel structure industrial plants, there must be fire compartments. Common fire compartments generally use firewalls, fire shutter doors, independent water curtains, automatic sprinkler devices, fire monitors, etc. Firewall panels are the most commonly used fire compartments. The individual wall panels are fixed on the lightweight keel to form an overall fire wall. However, after the fire-proof board is puttyed, due to the vibration of large machinery in the factory building, cracks often occur at the joints. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a method for anti-seismic cracking of fireproof gypsum wallboard joints, so th...
