Safety and precautions for fire-resistant container houses
Fire-proof residential container is a kind of steel structure board house. Now many board houses also use light steel keel as the main structure, so the use of steel structure in the construction industry is becoming more and more extensive. Today, the editor will mainly tell you about the hoisting method of steel structures, and understand the details of on-site construction of hoisting, such as on-site management, hoisting point selection and crane station selection, which are all important points in hoisting construction.
Safety and precautions for fire-resistant container houses
(1) Site and road treatment of the hoisting construction site: After the backfilling of the foundation works, a site with a width of 6-7m must be set aside 1.0m from the axis of the building as a road for cranes to travel, and the foundation is required to be solid and able to withstand the weight of the cranes. , in order to ensure the safety of hoisting machinery and hoisting operations.
(2) The hoisting adopts the backward hoisting.
(3) Selection of hoisting points: For the hoisting of steel columns, due to the small height of the steel columns, less than 16 meters, one or two hoisting can be used: for the hoisting of steel beams, two points are used when the length of the hoisting steel beam is less than 20 meters. When the length of the lifting steel beam is more than 20 meters, the four-point method is used for hoisting.
(4) Selection of crane station: The lifting capacity of the crane station must be guaranteed to meet the hoisting of components.
(5) Check calculation of the hoisting component body: Before the component body is hoisted, the construction check calculation of the body component should be carried out in terms of strength and stability to ensure that the body hoisting is feasible.
