1. Foundation requirements
The basic foundation planning of container houses generally requires rigid foundations and does not allow sinking or deformation cracking; the foundation needs to be compacted on the backfill.
2. Container house hoisting
After the container room of the single room is processed into finished products at the factory and transported to the construction site by the transport vehicle, the crane is hoisted to the specified position. When lifting, use four steel wire ropes to fix the four angle steel plate on the corner with bolts.
3. Container house field device
The on-site installation of the container house generally includes the following aspects: chassis positioning, structural assembly, and wallboard, walking circuit, and footing. At this point, the single container house is basically assembled.
4, Fire prevention and equipment
The container house is made of color steel plate with rock wool and slag wool which has its own fireproof and heat insulation properties; the space of the container house in the place, the placement of the fire exit, the fire interval, the number and arrangement of the fire stairs, the placement and quantity of the fire extinguisher All of them meet the relevant requirements. Fire exits shall be provided around the container house;
Fire separation interval: the interval between flammable and explosive dangerous goods warehouses should be greater than 25m;
The container houses arranged in groups shall not exceed 10 buildings in each group, and the interval between each building shall not be less than 3.5m, and the group and group shall not be less than 10m;
Safe evacuation: When the container house is 2 floors, 2 evacuation stairs should be set; the width of the evacuation stairs and corridor should not be less than 1m; the height of the outer corridor railing should not be lower than 1.05m.
5, Application and maintenance
Temporary construction and application should establish and establish various management systems such as safety and security, sanitation and epidemic prevention, fire protection, use of living facilities and life management. When the activity room exceeds the planned service life, the house structure and the enclosure should be fully reviewed, and the safety performance should be evaluated. Regularly carry out publicity and education on the safety, public security, fire protection, sanitation and epidemic prevention, environmental maintenance and other personnel of the living quarters.
Emergency plans for temporary construction of disasters such as preventing floods and floods should be established. A comprehensive review should be arranged before the rain and snow, and a solid reinforcement method should be adopted. During the operation of the container house, the original planning function shall not be changed. The applied load of the floor should not exceed the planned value. When the applied load of the floor exceeds the planned value, the structure should be evaluated for safety. During the operation of the container house, it is not allowed to open holes, punch holes or modify the structure at will, and the partition wall and retaining members shall not be removed by private lines. It is strictly forbidden to privately install, renovate and remove the temporarily constructed wires, electrical installations and electrical equipment. It is strictly forbidden to use high-power electrical equipment such as induction cookers. Do not store flammable or explosive chemical dangerous goods in the living area. With the temporary construction of air conditioning and heating equipment, the indoor temperature control should comply with relevant rules.
Arrange the relevant personnel to regularly check and maintain the temporarily constructed construction. The problems and safety hazards found during the review process should be promptly adopted. Before the mobile homes within the rule-period of the weekly transfer are assembled from the beginning, the main components should be viewed and maintained to meet the quality requirements. The maintenance of container room fittings shall comply with the following rules: Weld seams of load-bearing frames shall not be welded, and welds with serious corrosion shall be rust-repaired; the active link parts of structural parts shall be repaired with anti-rust oil after repair; When a tortuous deformation occurs, it should be corrected or replaced in time; when the door, window and accessories are broken or damaged, they should be corrected or replaced in time.
6, Removal and recycling
The removal of the temporary construction follows the criteria of “who installs, who withdraws”; when there is an unsafe situation that may jeopardize the temporary construction of all stability, the guidelines of “reinforcement and then removal” should be followed. Before the construction is removed, the construction unit shall prepare the removal construction plan, safety operation procedures and adopt relevant dust and noise reduction, accumulation, eradication and waste. Before the construction is removed, the work of water cut, power cut, and gas cut in the scope of removal should be done. During the removal process, the site shall not use the distribution box that was temporarily constructed.
The removal of the construction shall comply with the environmental protection requirements, and the removed construction materials and construction waste shall be sorted in time. Floors and operating channels shall not collect and build materials and build garbage. The construction of garbage should be carried out according to the rules and must not be burned at the construction site. Fences and warning signs shall be placed around the construction area, and special personnel shall be placed in custody. Temporary construction may not be carried out in the event of severe weather such as winds, fog, rain or snow. When the temporary construction with a height of more than 2m is removed, the operator should operate on the specially constructed scaffolding or stable structural parts, and the operator is strictly prohibited from standing on the component to be dismantled. After the withdrawal, the venue was cleaned up in time.
