STANDARDS OF NEW DESIGN AND CONSTRUCTION FACTORY OF 329 CONSTRUCTION COMPANY
329 Construction Company Limited is a large contractor in Saigon, specializing in the construction of new construction, renovation, upgrading and repair of industrial factories.
With many years of experience in the construction field, 329 Construction Company Limited is committed and guaranteed to bring to customers the most perfect works, the best quality and the most reasonable prices.
In order to completely build a quality and durable factory, 329 Company always adheres to the following design standards:
Standard of design of the factory floor
If the design of the factory floor is on soft ground, it is necessary to The foundation must be treated in accordance with the geology, to avoid foundation subsidence.
When designing the factory floor, the contractor must ensure according to the technology requirements to choose the suitable background structure for each type of foundation as follows:
Concrete floor
Steel
floor Cement tiled floor
Plank, wood, plastic floor.
If the design of the workshop is for the warehouse area, the viaduct is used for loading and unloading materials, the floor of the workshop is required to be flat.
The factory floor surface requires a hard lining with a minimum thickness of more than 0.1m and a fast drainage system to avoid water stagnation.
The design of the concrete factory floor must be divided into cells with a maximum length of 0.6m, between the foundation cells, they must be inserted with Bitumen panels.
The width of the summer platform is required to be 0.2-0.8m, with a slope of 1-3%.
Standards for design drawings for the foundation of the factory
The standard for the design of the foundation of the factory must be consistent with the physical and mechanical properties of the foundation and the typical natural properties of the building foundation.
The design of the factory foundation has a height of the foundation surface lower than the ground surface with the following difference:
For reinforced columns: 0.2m difference
For columns with wall inserts: 0.5m difference
For reinforced concrete columns steel : 0.15m difference
For the height of the steel column base of the corridor, viaduct to park the pipes between workshops, must be at least 0.2m higher than the leveling height.
The design of the factory column foundation with expansion joints and the workshops with the expected expansion needs to be designed in common for two adjacent columns.
For foundations under brick walls, masonry walls, if it is a frameless house: the foundation depth is less than or equal to 15cm, it is necessary to design wall support beams and the upper surface of the supporting beams must be at least 3cm lower than the finished foundation.
The design of the workshop foundation for the part subjected to high temperature impact must be protected using a layer of heat-resistant material, the foundation subject to corrosive impact must use anti-corrosion material.
Factory roof design
standards Standard factory roof slope according to materials : Factory roof slope depends on roofing materials :
Factory uses asbestos-cement roof sheets : 30-40% slope
Standard degree corrugated iron roof slope: 15-20% slope
Factory roof tiled roof: slope 50-60%
Reinforced concrete roof factory roof slope: 5-8%
slope Factory roof slope less than 8%, heat joints must be arranged in the waterproof reinforced concrete layer and the distance between the thermal joints is over 24m along the house.
For the design of the factory's drainage system at the roof, it depends on the roofing material and technology requirements:
For the design of the workshop with a roof door or a level roof with a deviation of 2 roofs greater than or equal to 2.4 m must have gutters and drains. If the difference between the two roofs is less than 2.4m, it is not necessary to make a gutter, but measures must be taken to strengthen the lower roof in the amount of storm water.
For mixed roofs with lighting and ventilation functions, vertical glazing is mandatory. The length of the roof door is less than 84m, set back 1 step from the gable column. Roof doors must not have heating, steaming or moving devices.
If the workshop generates heat, moisture, and movement, it is necessary to have a ventilated roof door so that it must have a roof to prevent rain from entering, without glazing, but only leaving a gap with a height of 0.15 - 0.3m.
Arrange an angle to prevent rain from falling less than 150 for rain-resistant manufacturers or in the space where the shutters are arranged, the angle of anti-rainfall of the upper roof can be increased by 450, the spokes must not be made of metal. fragile material.
The roof door part requires fixed glazing, the lower part is open, the upper part has a racing roof and the glass thickness is >= 3mm. If the design drawing has a crane, the roof door must be fitted with a glass protection net of at least 0.7mm wide. If the reinforced glass does not need a protective net: the glass is installed vertically and equal to the projection of the door frame when the door frame is tilted or horizontal.
When designing a workshop, the choice of roof types such as: factory drawings of dome, sawtooth, letter M, frill,... must depend on technology and workshop orientation.
Design standards for walls and partitions of factories
If a brick wall is used, it must have a rain-proof, moisture-proof layer with a cement mortar of grade 75, 20cm long, placed horizontally on the floor when finishing.
For partition walls, they should be designed so that they can be easily disassembled.
When designing factory walls, it is necessary to design a maximum span of 12m, a maximum height of 6m.
Design standards for windows and doors
The maximum height of the door is 2.4m from the floor and must be able to open and close the door.
Window height greater than 2.4m must be fixed into a fixed frame for protection and in case of necessity, a door must be installed
