How to improve the sound insulation effect of steel structure workshop?

The construction of steel structure workshop is mainly divided into the following parts: 1, embedded parts, (which can stabilize the workshop structure) 2, columns, generally using H-beams or C-beams (generally using angle steel to connect two C-beams) 3, beams, generally using C-beams and H-beams, (the height of intermediate products depends on the span of beams) 4, purlins: generally using C-beams and Z-beams. 5, support, brace, generally round steel. 6. There are two kinds of ceramic tiles, one is single tile (color steel tile). The second is composite plate. Polyurethane or rock wool is sandwiched between two layers of color-coated boards, which plays the role of warm in winter and cool in summer, as well as sound insulation and fire prevention.

The external wall panel adopts double-layer wallboard system, with ordinary concrete precast slats on the outside and light steel keel gypsum board on the inside; The interior partition wall is made of light steel keel gypsum glass wool.

The main advantages of Shibuya/Steel Structure Workshop are as follows:

1, light weight, high strength and large span: although the density of steel is higher than other building materials, its strength is very high. Under the same stress, the steel structure has small self-weight and can be made into a long-span structure. 2. Short construction period: the structural parts of the workshop are mainly prefabricated in the factory, transported to the site and installed, and the assembly work is convenient to build. 3. High fire resistance: when the surface temperature of steel is within 150℃, the strength changes little, and when the temperature exceeds 150℃, the strength decreases obviously. Generally, the surface of steel structure will be coated with fire retardant paint, and then a protective film will be formed to make the components fire-resistant to the limit. Of course, it is also very important to divide the fire zone reasonably and use the fire shutter.

1. Type of steel sandwich: the sandwich (common wooden board) existing in the steel sandwich, that is, the first floor space of the building is divided into two floors in the form of horizontal floor separation. The type of building where the partition is located.

Seepage prevention and waterproof: rainwater mainly penetrates through joints or gaps. In order to prevent seepage and water, it is necessary to use a sealing washer at the screw mouth, and then adopt a hidden fixing method. The overlapping parts of the plates are treated with sealant or welding. The long board is to eliminate overlap, and the bulge at the joint is strictly waterproof.

The unit price is around, usually a single layer. Double-decker, generally-roughly the unit price. The spacing between the national steel bars of the upper and lower millimeters shall not be greater than.

Sound insulation: Fill the metal roof with sound insulation materials (usually glass wool), or coat the surface of metal tile with heat insulation and reflective paint.

If you don't want to use plywood, if the density of the auxiliary keel is dense enough, after laying a layer of steel mesh on it, you can even use fine steel bars and cement to pour a floor with a thickness not exceeding.

Ventilation and cooling: Generally, there is no super-high-power heating equipment in high-rise factories, people are not very dense, and there is no odor and dust. Just use the roof ventilator+gas building. The steel structure workshop with high structure and long span is to install an exhaust fan with large exhaust air volume on the roof to exhaust the air to the outside; Forming indoor negative pressure; A large amount of fresh air forcibly enters the workshop from around the workshop, forming air convection; The effect is better.

Good lighting: install lighting boards or lighting glass at special positions on the roof. Considering the service life of the skylight and its coordination with the roof panel, the joints must be waterproof.

If there is no fixed condition for laying parallel to the short side, it can also be laid parallel to the long side. Then weld the secondary keels between the primary keels. The auxiliary keel can be made of equilateral angle steel with the specification of 1000 or above.

Better factories are built of steel structures. The construction site and effect of thick and fast-loading partition wall structure (sound insulation) light and fast-loading partition wall are shown in the figure. Then the conduit is laid between two layers of steel bars in advance, and the conduit is buried in concrete. It is generally not recommended to dig the buried pipe of the floor after the completion of the floor, which will affect the quality of the floor more or less. And there is an extra slotting fee.

Noise control at the boundary between the computer room and the production workshop should be considered from the following aspects:

1, plant construction of plant equipment room

Under the condition of ensuring the rationality of the infrastructure layout of the equipment room of the production plant, the machinery room and equipment room of the plant should be provided with sound absorption and insulation layers, sound insulation doors and windows, and the equipment room of the plant should be divided into areas and equipped with precision equipment that meets the seismic requirements. Minimize the impact of noise and vibration on the surrounding environment. According to different noise sources, corresponding sound insulation and noise reduction measures are taken.

2. Foundation excavation

During foundation excavation, vibration isolation should be carried out. For example, a vibration isolation trench is set around the foundation. Generally, a vibration isolation trench with a depth of 1 m and a width of 0.4 m is dug, a rubber damping pad is added above the damping layer, and other necessary treatments are made on the rubber damping pad. Finally, the vibration isolation trench is leveled with the ground with steel plates.

3, equipment installation noise cover

For machinery and equipment with noise as the main source, it is necessary to reduce noise radiation from the noise source and install sound insulation cover, which can make other noise control measures play a greater role, thus improving the overall sound insulation and noise reduction effect. Due to the different requirements of sound source equipment for sound source type, overall size, ventilation and heat dissipation, it is necessary to conduct on-site investigation, analysis, design scheme, and manufacture sound insulation cover.

4, equipment installation

When installing equipment, it is necessary to design shock absorption and take vibration isolation and shock absorption measures at the bottom of the equipment. According to the weight and vibration frequency of the equipment, the shock absorption treatment is designed. Commonly used shock absorption products include shock absorption rubber, spring shock absorber, rubber shock absorption pad, shock absorption platform and so on. According to the connection mode of seismic source and supporting seismic source, vibration reduction/isolation methods can be divided into active vibration reduction and passive vibration reduction. According to different forms of vibration, solid vibration isolation and damping vibration reduction can be used to control it. The selection of damping materials should be based on actual working conditions, such as ambient temperature, source amplitude, weight, stiffness, vibration frequency, etc. After professional analysis, the technical scheme of shock absorption is formulated and the correct shock absorption products are selected.
