Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel structure enclosure system, and particularly relates to a waterproof joint of structural member out of metal roof and a processing and installation method. BACKGROUND

[0002] The metal roof is widely applied to industrial plants, large-scale stadiums, warehouse logistics facilities and other buildings due to the characteristics of light weight, high strength, convenient construction and good durability. However, the part where the structural member (such as a pipeline, a support, a fan, an antenna pedestal and a steel column) penetrates out of the metal roof is a weak link of the waterproof project, and the related water leakage problems account for more than 60% of the metal roof leakage accidents, which seriously restricts the quality of the metal roof.

[0003] The joint of the structural member out of the roof is prone to become a “high-risk penetration point” of rainwater, snowmelt and condensate water: rainwater forms “pressure water” under the action of wind and penetrates into the indoor along the gap between the structural member and the roof; when the snow melts, the water penetrates through the capillary action or the gap. If the waterproof treatment is improper, it will cause damage to indoor equipment, corrosion of structural steel bars, failure of the thermal insulation layer due to dampness, and even affect the safety and service life of the building; for industrial scenes such as electronic plants, it may also interfere with the production process and cause economic losses.

[0004] The traditional waterproof method has obvious limitations: the sealant is easily affected by ultraviolet rays, temperature changes and vibration, and appears aging, cracking and falling off, and the service life is only 3-5 years; the adhesion between the roll material and the metal roof and the structural member is poor, and the roll material is prone to curling under wind pressure or structural deformation; and the node processing lacks systematic design and does not consider the drainage path and expansion compensation, which is difficult to adapt to the dynamic deformation of the roof.

Then, the few purlins 33 are installed, before the roof panel 34 is fixed formally, the few purlins 33 are inserted into the clamping groove and placed in the middle, so that the few purlins 33 are kept in a non-connected state with the steel plate 31 to reserve a sliding space. Then, the fixing and sealing treatment of the roof panel 34 is performed: butyl cement 40 is pasted around the position below the roof panel 34 corresponding to the few purlins 33, butyl sealing tube glue 39 is pre-coated at the place where the roof structure nail 38 is applied, and the roof panel 34 and the few purlins 33 are tightly connected by using the roof structure nail 38; for the hole at the wave peak of the roof panel 34, the rubber inner plug 36 is embedded into the hole by 5 mm in depth, then the polyurethane sealing glue 37 is fully coated on the gap between the rubber inner plug 36 and the hole and on the rubber inner plug 36, to complete the local sealing.
