Mobile container houses can achieve wind, water, earthquake, and lightning protection through structural design, standardized construction, and daily maintenance. Four landing solutions are provided for each of the four requirements:
1, Windproof: relying on steel structure design to meet the corresponding level of windproof requirements
The main body of a qualified movable container house is a light steel structure. Conventional products can withstand strong winds of 9-13 levels, while reinforced products can withstand strong winds of 12 levels or above. The wind resistance can be strengthened through the following methods:
During the installation phase, choose a flat and solid site, fix the foundation properly, and avoid building in soft, low-lying or slope areas
Strictly follow the design specifications when building multiple layers, and increase the overall weight and tie fixation of the structure
Before issuing a strong wind warning, reinforce the box connection in advance, clean up the surrounding high-altitude debris, and avoid external impact damage
2, Waterproof: full process protection from production installation to use
Container room water leakage often occurs in the joints and roof connections, and can be effectively waterproofed through standardized processes:
Production and processing stage: The folding version will be equipped with a dedicated waterproof device at the connection point, and the top plate will be designed with convex edge ring groove insertion and sealing gasket to achieve dual protection; Qualified weather resistant sealant will be applied to the gaps of the roof panels, and the steel plates will be processed into a concave convex joint structure to reduce the probability of water leakage
Installation stage: Install sealing strips at the connection positions of the boards, apply waterproof adhesive to the internal and external corners and joint seams, lay waterproof rolls or coatings on the top plate, and conduct water storage tests and inspections after completion
Usage stage: Design inclined drainage channels on the roof, clean the drainage channels regularly to avoid debris blocking the drainage, regularly check for cracks in the sealant and aging of the sealing strip, and repair and replace them in a timely manner
3, Seismic resistance: The structure itself has natural advantages and can be reinforced and improved
The main body of the container house is a fully steel modular structure, which is designed to withstand earthquakes of magnitude 8 and has inherent seismic advantages
Steel itself has good ductility and can absorb seismic energy through deformation. Modular design can adapt to foundation deformation and reduce the overall risk of damage
Strengthen the foundation during construction, choose pile driving or compaction treatment according to geological conditions, and improve the stability of the foundation
Optimize node connections, use high-strength bolts or welding to ensure connection reliability, use lightweight decoration materials as much as possible indoors, and fix furniture and equipment to avoid secondary damage
Regularly inspect the structure, promptly repair node damage after multiple relocations, and ensure structural strength
4, Lightning protection: Comprehensive system protection+regular maintenance can ensure safety
Container houses are often built on outdoor construction sites, and lightning protection systems must be in place. The core relies on dual protection of grounding and lightning protection devices:
Establish a good grounding system (core): Use galvanized steel pipes or angle steel to drive more than 1.5 meters underground as grounding electrodes, and then connect them with flat iron to form a grounding grid, controlling the grounding resistance to be below 10 ohms; If the soil resistivity is high, salt or charcoal can be sprinkled to assist in reducing the resistance, and finally the grounding electrode can be sealed with concrete to avoid rainwater erosion
Install lightning protection device: Weld galvanized round steel with a diameter of 12mm or more along the edge of the roof as lightning protection strip, and fix it with brackets every 1 meter; Lightning rods with a height exceeding 1 meter above the roof can also be installed; If it is a metal roof, the roof can be directly used as a lightning arrester, as long as it is reliably connected to the grounding system
Standardize internal wiring: wires should be shielded through metal tubes, and the vertical part of the main line should be arranged as close as possible to the center of the building to avoid being close to the down conductor and reduce the induction range
Regular maintenance inspection: Check the grounding resistance every six months. Before the thunderstorm season, check whether the lightning protection strip is broken, whether the bracket is loose, and whether the lightning rod is corroded. If the value exceeds the standard, rectify it in a timely manner.
