The steel structure produced by Dalian Guangtong Steel Structure Co., Ltd. has the advantages of light weight, high strength, good overall rigidity, corrosion resistance, environmental protection and energy saving. The eight key points of design and construction of steel structure workshop of Dalian Guangtong Steel Structure Co., Ltd. are as follows:
1. bearing capacity
The steel structure workshop shall be able to bear the construction load, rainwater, dust, snow pressure and maintenance load. The bearing capacity of the metal roof slab is related to the section characteristics of the slab type, the strength and thickness of the material, the mode of force transmission, and the spacing of purlins (auxiliary purlins).
The building area of the steel structure workshop is generally large. In the daytime, improving the indoor lighting through the skylight can save energy. When arranging the lighting board or glass at the specific position of the metal roof, the service life of the skylight shall be coordinated with the metal roof panel, and the connection between the skylight and the metal roof panel shall be waterproof.
Especially in the rainy season in summer, prevent the condensation of water vapor in the metal roof bottom layer and metal roof layer, and drain the water vapor in the metal roof layer. The solution is to fill thermal insulation cotton in the metal roof layer, lay waterproof membrane on the metal roof bottom plate, and there are ventilation nodes on the metal roof panel.
4. lightning protection
There are many thunderstorms in summer. When designing steel structure workshop, it is necessary to lead the lightning to the ground to prevent the lightning from breaking through the metal roof and entering the room.
5. fire prevention
In the process of using steel structure workshop, fire is a big hidden danger, so fire prevention measures should be taken. In case of fire in the steel structure workshop, the metal roof materials will not burn and the flame will not penetrate the metal roof panel.
6. seepage control
In addition to leakage prevention, the steel structure workshop must also prevent rainwater from seeping into the metal roof panel from the outside. Rainwater mainly enters into the metal roof through lap joints or nodes. To achieve the function of anti-seepage, it is necessary to use the sealing washer at the screw mouth and then use the hidden fixation, and use the sealant or welding treatment at the overlap of the plate.
7. noise insulation
The general steel structure workshop is mostly used in the production workshop. In the process of production and construction, it is inevitable that there will be noise. In order to prevent the sound from outside to inside or from inside to outside, the steel structure workshop will be built. The metal roof layer is filled with sound insulation materials (usually insulation cotton), and the sound insulation effect is expressed by the difference of sound intensity on both sides of the metal roof layer. The sound insulation effect is related to the density and thickness of the sound insulation material. It should be noted that the sound insulation materials have different blocking effects on the sound of different frequencies.
8. thermal insulation
On the other hand, we should keep warm in winter. Prevent the heat transfer on both sides of the metal roof of the steel structure workshop, and make the indoor temperature stable. The thermal insulation function is realized by filling thermal insulation materials (commonly used glass wool and rock wool) under the metal roof panel. The thermal insulation effect is expressed in U value, and the unit is w / m2k. The heat preservation performance is determined by the following factors: the raw material, density and thickness of the heat preservation cotton; the humidity of the heat preservation cotton; the connection mode between the metal roof panel and the lower structure; and the repeated ability of the metal roof to the heat radiation.
