The color steel plate activity room is a building that is quick and easy to dismantle. Not only is the practicality very strong, but it also has environmental protection and energy saving. Here we will talk about the dismantling method and dismantling process of Caigang House. Basic ideas before the dismantling of Caigang: Pre-demolition work: comprehensively check whether the fastener connection, wall-connecting parts and supporting system of the scaffold meet the requirements of the construction; supplement and improve the demolition order and measures in the construction plan according to the inspection result, and implement it after approval by the competent department; responsible for the project construction People perform the dismantling of safety technology; remove debris and obstacles on the scaffold. When dismantling, it should be done: The demolition work must be carried out layer by layer. It is forbidden to work up and down at the same time; the wall parts must be removed with the scaffold layer by layer. It is strictly forbidden to remove the entire wall or several layers before removing the scaffold. Section height difference should not be greater than 2 steps, if more than 2 steps should be added to reinforce the wall; when the scaffold is dismantled to the height of the last long pole in the lower part, it should be erected in place after temporary reinforcement and then removed. With wall parts; when the scaffolding is segmented and separated, the ends of the scaffold that are not to be dismantled shall be provided with wall elements and transverse bracing reinforcements in accordance with the requirements of the specification; all constitutional parts are strictly prohibited from being thrown to the ground. The following is the removal method of color steel house: 1. Before the demolition work begins, the branch lines leading to the demolished buildings, such as wires and natural gas pipelines, should be cut off or relocated. 2. Prior to the demolition of the building, safety rails should be set up around the entrance and other people should not be allowed to enter. 3. The demolition of buildings shall comply with the demolition plan and proceed from top to bottom. It is prohibited to dismantle several floors at the same time. Demolition workers should stand on a scaffold or a stable structure to operate. When a certain part is removed, other parts must be prevented from collapsing. After the beams and columns are removed, the entire structure of the load-bearing parts should be removed. 4. Before the demolition, structures that are in danger of collapse should be temporarily reinforced with pillars. 5. When demolishing a building, many people are not allowed to gather and concentrate materials on the floor, and larger or heavier materials are removed According to the requirements of the drawings and the characteristics of the color board building, the dismantling process is: 1. Demolition of the house bread side → Demolition of the roof panel → Demolition of the second floor partition plate → Demolition of the C-steel beam on the roof → Demolition of the surrounding two-story tie bar → Removal of the lower buckle plate → Demolition of the wooden floor → Demolition of the corridor steel plate → Demolition of the lower partition wall → Second floor Demolition of C-shaped steel girders on floors, removal of surrounding columns, cleaning of site materials. 2. The demolition work should be carried out by the relevant professional qualification manufacturers, and unauthorized removal is forbidden; the other principle of demolition is “first dismantling and then dismantling, and later dismantling firstâ€. When the electric box is installed on the floor of the movable house, the wooden ladder is used. The ascending ladder on the person-to-roof is also applied with a wooden ladder or temporary scaffolding up to the roof; all the edges of the roof are removed and the roof panel is removed one by one in the order. Then put it in the tool bag or special tool box. Then remove the second floor partition board and upload the partition board to the ground to keep enough space for the removal of the second floor. After dismantling the C-shaped steel girder on the roof, the dismantling staff cooperate with it to pass down and transport it away from the activity house site. Remove the color steel plate around the second floor including the pull rod and clean the site. Then remove the lower gusset. Remove the two-story wooden floor and clean the site. Dismantled the two-story corridor steel plate, including the railing corridor demolition. Remove a partition wall, remove the upper floor beam C-shaped steel, and clean up the field. The two-story C-shaped steel beams were dismantled in sequence, and the surrounding columns including the color steel plates were dismantled in a sequence. After all the above are removed in sequence, the materials of all the color board houses shall be cleared out of the construction site. The materials of the reconstructed activity room must be re-entered and must be checked and checked before being used.
