Problems solved by technology

[0003] Traditional steel structure roof raised skylights are mostly waterproofed by thermally bonding SBS around the skylight, but there will be water between the peaks, and the waterproof membrane will age after a few years, so the leakage is more common and seriously affects Use function, and the SBS waterproof skirt affects the exterior appearance of the building, which leads to poor waterproof quality of the existing steel structure roof raised skylight. In order to restore its waterproof effect, it is necessary to replace the waterproof membrane and re-bond SBS. It will not only increase the cost of construction and maintenance in the later period, but also bring unnecessary troubles to consumers.

Embodiment 1

[0031] The steel structure roof raised skylight waterproof construction method of the present invention comprises the following steps:

[0032] S1. Construction preparation: drawing construction drawings and purchasing materials;

[0033] S2. Construction positioning: Determine the position of the skylight opening on the roof panel according to the drawings and perform positioning by marking, and reduce the size of each side of the opening by 50mm for later production of the internal diversion groove, and lay pedestrian passages around the opening of the skylight to prevent falling from high altitude;

[0034] S3. Opening cutting: Drill four holes with a diameter of 12mm at the four corners of the defined skylight opening, and use a reciprocating saw blade to cut off all the peaks at the roof where the skylight is installed, and then use a hand-held shears to cut the roof In the flat area, avoid the insulation cotton, fold up the cut roof panel and remove it, and clean the roo...

Embodiment 2

[0045] Dingyu logistics warehousing project 2# logistics warehouse project: the structure type is steel structure, the ground floor is partly two floors, the construction area is 3052㎡, the start date is October 8, 2018, the construction method is the same as the embodiment, and the completion date is 2019 On October 8, after the installation was completed, a single-stage water spray test was carried out, and there was no water seepage or wet stains, and it has been used so far without damage.

Embodiment 3

[0047]Construction of Beijing Jiaotong University Seaside Rail Transit Comprehensive R&D Experimental Base (Tender 1)-B7# project: the structure is a portal steel frame light steel structure, the ground floor is partly two floors, the construction area is 4520.97㎡, and the start date is April 2018 On the 5th, the construction method was the same as that of the embodiment, and the completion date was May 31, 2019. After the installation was completed, a single-stage water spray test was carried out, and there was no water seepage or wet stains, and it has been used so far without damage.

[0048] The steel structure roof raised skylight waterproof construction technology used in Examples 1-3 uses the double waterproof construction method of outer deflector + inner diversion groove, which can not only ensure the waterproof purpose of installing raised components on the steel structure roof, but also achieve economical efficiency. Aesthetic effect. The construction components are...

Abstract

The invention relates to the technical field of house building engineering, in particular to a waterproof construction method for a convex skylight of a steel structure roof. The method is simple and fast to assemble on site, attractive and elegant after being installed, good in waterproof effect, long in service life and capable of reducing leakage and aging conditions and saving later-period maintenance cost. The method includes the steps of S1, construction preparation; S2, construction positioning; S3, opening cutting; S4, supporting channel steel installation; S5, color steel plate sewing; S6, inner diversion trench mounting: reinforcing four corners of an inner diversion trench by adopting corner plates and durable structural adhesives, and fixedly mounting the inner diversion trench at an opening of the skylight; S7, skylight frame mounting; S8, rhombic flow guide plate installation; S9, wave crest rubber plug installation; S10, bottom side drain hole forming; and S11, water return prevention rain cover arrangement.

Description

technical field [0001] The invention relates to the technical field of building construction engineering, in particular to a waterproof construction method for a raised skylight on a steel structure roof. Background technique [0002] With the development of the construction industry, building materials are constantly being updated. Steel structure buildings have become more and more popular. Due to their advantages of light weight, high strength, and short construction period, they are more and more widely used in industrial buildings. Moreover, most factories now choose to install roof raised skylights, fans and other components in order to obtain a comfortable environment and lower energy consumption. [0003] Traditional steel structure roof raised skylights are mostly waterproofed by thermally bonding SBS around the skylight, but there will be water between the peaks, and the waterproof membrane will age after a few years, so the leakage is more common and seriously aff...
