Convenient disassembly and assembly, short installation period, especially suitable for emergency engineering needs.
The house is light in weight, and15t truck can carry all parts of 80M2 trailer, so it is convenient and economical to transport.
Standardized standard components can be used to assemble mobile homes with different areas and uses according to users' needs.
The main material of phosphorus-magnesium mobile house is phosphorus-magnesium sandwich mobile board, which is characterized by good heat insulation effect. Convenient installation and disassembly. Products are especially suitable for large factories, construction engineering headquarters, engineering management departments, urban construction sites, offices, staff quarters, kitchens, restaurants, warehouses, cement depots and large construction sites.
Verb (abbreviation for verb) Types and styles of mobile homes:
Types: light steel combined house, mobile house, cement trailer, container trailer, color steel box, phosphorus magnesium trailer, etc.
Style: (single layer) single slope. (Single layer) Double slope (Double layer) Single slope. (Double deck) Double slope.
Six, mobile home use:
Offices, sales offices, classrooms, shops, teahouses, exhibition halls, hospitals, dormitories, canteens, industrial workshops, warehouses, parking lots, simple sheds, single-slope houses, mobile kiosks, mobile villas, on-site temporary facilities, etc.
Seven, area calculation method:
[1] 1. The area of the board house is calculated by multiplying the length and width of the external wall by the number of floors.
2. Outdoor stairs and walkways are calculated according to the sum of the projected areas of the natural layer.
3. The awning is calculated as half of the horizontal projection area.
4, the wallboard does not calculate the construction area.
5. Total area = (1)+(2)+(3).
There are two stairs on the standard floor, one on the left and the other on the right. When the stairs increase or decrease by 4.5CM2, increase or decrease the stairs according to this number.
7. Unless otherwise specified, the calculation method of quantities shall be adjusted and settled according to the above calculation formula.
Seven. Pricing principle of mobile residence: mobile residence
Calculated by square meter: square number * unit price+freight = final price.
Installation method of trailer:
Movable board houses are similar to buildings, and the surrounding and partition foundations are leveled. It is better to use reinforced concrete, which is relatively strong; Then erect columns, connect the skeleton with beams, and install partitions, external walls and door and window frames; Along the floor, then install a layer upwards, and then install the roof truss and roof panel; Finally, install doors and windows. , and pull the vertical bracket. There are sanitary ware and hardware.
In fact, this is a light steel structure, which is very similar to a heavy steel structure factory building.
The concealed work of the mobile home refers to the parts to be covered by the next process after the last process is completed. If the concealed work is not done well, it is futile to decorate the surface beautifully.
"Concealed engineering" can be divided into water installation, electrical installation and moisture-proof and waterproof engineering. Every one of these projects can't be ignored. Problems in any link may bring serious economic losses and even endanger personal safety. The construction technology and material appraisal of waterproof engineering can avoid unnecessary economic losses and injuries. [Edit this paragraph] Trailer 1 Precautions for use. If the color steel board room uses polystyrene as the sandwich panel, it is necessary to pay attention to fire prevention. If welding construction is not allowed near the wall, a fire prevention device should be installed on the heating furnace in winter, and metal pipes should be used when laying indoor lines. The metal pipes should be reliably grounded or fire-resistant pipes, and sleeves should be added for protection when passing through the wall. It is forbidden to use blowtorch on the roof that needs waterproof treatment! When the roof tile iron sheet is less than 0.6 mm in the open area, a lightning rod should be installed in the house.
2, color steel board room should pay attention to the wind. Color steel plate houses are light in weight, simple in structure and weak in wind resistance. In order to improve the wind resistance, customers should try to choose the board houses of regular manufacturers, and don't just pay attention to the cheap price, leaving future troubles. For customers who have installed windproof board houses, 4×4 angle steel can be fixed on the roofs above the front and rear walls along the length direction of the board houses.
3, light steel structure residential purlin model should not be too small, after the completion of construction, it depends on the connection and reinforcement of each part.
Mobile home structure:
1, roof truss, purlin, the main beam is assembled and welded by 40 # angle steel and some 50 # channel steel, and the minor beam is made of 40 # angle steel in a T-shape.
2. Corner columns and center columns are made of channel steel and angle steel columns.
3. The floor is made of solid calcium silicate board, specification: 1500mm×750mm×40mm.
4. The wallboard is calcium silicate board, and the specification is: 1500mm×2700mm×30mm.
5, there are two kinds of roof tile:
(1): Nailless waterproof, heat-insulating and fireproof composite board.
(2): 840 corrugated tile, color steel plate, with sealing plate (red, green, yellow and blue for users to choose).
6. Paint the interior and exterior walls, so paint the steel structure members.
7. Ordinary wooden doors with luxurious ball locks are installed at the door, and the windows are push-pull plastic steel windows, with two windows in one room. Specification of plastic-steel window: 1460mm×900mm.
Characteristics of light steel trailer:
Light steel trailer 1. The number of disassembly and assembly can reach 8- 10 times.
2. Wind resistance grade 9
3. The seismic capacity is 7.
4. Fire rating 1.
5. The average dead weight is 60kg/ m2.
6. Floor slab bears live load 160kg/ m2.
7. The installation time is 100 m2/ day.
8. Each demolition loss is 2-6%
