With the continuous development and progress of the times, steel structure workshop is more and more common in our life. In the past, we can only imagine that we can see the effect picture before it is built. In recent years, with the continuous development of science and technology, steel structure animation has gradually come to our vision, which can more intuitively show the wonderful after completion, which is invisible increase in the process of customer negotiation Added a few points to the odds.

Precautions for roof design of steel structure workshop

Anti seepage: prevent rainwater from seeping into metal roof panel from outside.Rainwater mainly enters the metal roof through lap joints or joints.In order to achieve the function of anti-seepage, it is necessary to adopt concealed fixation after using sealing washer at the screw mouth, use sealant or welding treatment at the lap joint of the plate, and it is better to use a full-length plate to eliminate the overlap, and tight waterproof treatment of abdominal distension at various joints.

Fire prevention: the metal roof material will not burn in case of fire, and the flame will not penetrate the metal roof panel.

Anti wind pressure: resist the local maximum wind pressure, and the metal roof panel will not be pulled off by negative wind pressure.The wind resistance performance is related to the buckle force of metal roof panel and fixed seat, and the density of fixed seat.

Sound insulation: to prevent sound from being transmitted from outside to inside or from inside to outside.The sound insulation material (usually made of insulation cotton) is filled in the metal roof layer. 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 sound insulation materials.It should be noted that sound insulation materials have different blocking effects on different frequencies of sound.

Ventilation: indoor and outdoor air exchange.Air vent shall be set on metal roof.

Moisture proof: prevent the condensation of water vapor in the bottom layer of metal roof and metal roof layer, and drain the water vapor in the metal roof layer.The solution is to fill the metal roof with insulation cotton, lay waterproof membrane on the metal roof bottom plate, and have ventilation nodes on the metal roof panel.

Load bearing: Bear construction load, rain water, dust, snow pressure and maintenance load.The load-bearing performance of metal roof panel is related to the cross-section characteristics of plate type, the strength thickness of material, the way of force transmission and the spacing of purlins (auxiliary purlins).

Lightning protection: lead the lightning to the ground to prevent the lightning from breaking through the metal roof and entering the room.

Heat preservation: prevent heat transfer on both sides of metal roof to stabilize indoor temperature.The insulation function is realized by filling thermal insulation materials (glass wool and rock wool commonly used) under the metal roof panel. The thermal insulation effect is expressed by U value, and the unit is w / m2k.The thermal insulation performance is determined by the following factors: the raw material, density and thickness of the insulation cotton; the humidity of the insulation cotton; the connection mode between the metal roof panel and the lower structure (to prevent the “cold bridge” phenomenon); the repeated ability of the metal roof layer to heat radiation.

Daylighting: improve indoor lighting through skylight during the day to save energy.When the lighting board or glass is arranged at the specific position of the metal roof, the service life of the skylight shall be coordinated with the metal roof panel, and the waterproof treatment shall be done at the joint of the skylight and the metal roof panel.

Beautiful: the metal roof has good texture and pleasant color.

Control thermal expansion and cold contraction: control the shrinkage displacement and direction of metal roof panel.To ensure that the metal roof panel will not be damaged by the stress caused by thermal expansion and cold contraction in areas with large temperature difference.

Anti avalanche: the metal roof in the snowfall area is equipped with snow barrier railings to prevent the snow from sliding suddenly.

Icicle: to prevent rain and snow from forming icicles at the cornice.
