Construction method of skyline plate assembled roof coating waterproof layer at gutter

Abstract

The invention provides a construction method of a skyline plate assembled roof coating waterproof layer at a gutter. The construction method comprises the steps of pouring polymer mortar, pasting a polyethylene polypropylene fiber coiled material, spraying a concrete interface agent, applying an additional waterproof layer, and laying a first waterproof layer, a second waterproof layer and a third waterproof layer, so that the waterproof effect at the gutter reaches the level I, wind uplift resistance, dislocation resistance and aging resistance can be effectively achieved, all the steps are mutually linked and completed at a time, the construction mode of a conventional waterproof layer at the skyline plate assembled roof gutter is overturned essentially, and the overall load of a skyline plate roof is reduced. The construction method has the obvious and outstanding characteristics and can further be used for waterproof construction of other parts of the assembled roof and even a conventional building roof and the like.

Description

technical field [0001] The invention belongs to the technical field of building roof waterproof construction, and in particular relates to a construction method of a skyboard assembled roof paint waterproof layer at a gutter. Background technique [0002] For prefabricated buildings, the production of the gutter is generally to set up a grooved skyboard on one side of the outer wall panel, the other side of the grooved skyboard is connected to the roof panel, and the upper left end of the grooved skyboard is equipped with a water barrier. The upper right end of the skyslab is equipped with aerated concrete blocks, and the construction process of the gutter waterproofing is combined with figure 1 A brief description is as follows: [0003] 1. Pouring concrete leveling layer 6: Continuously pour a certain thickness of fine stone concrete on the inner surface of roof panel 1, aerated concrete block 3, grooved sky panel 5, water retaining plate 4 and outer wall panel 2 and wipe...

AI Technical Summary

Problems solved by technology

[0011] 1. When the wind is strong, a wind vortex will be formed on the side wall of the gutter, and the wind vortex will cause a small amount of shaking on the skyboard of the entire roof. These shakings will cause debonding and cracking between the waterproof membrane layer and the roof. When the waterproof membrane is laid Welding at the seams, especially the yin and yang corner welding is complicated, and shaking will also cause these welds to be pulled apart. The above two situations will cause the roof to lose its waterproof effect

[0012] 2. Under the influence of strong winds or surrounding vibrations, the roof slabs will be misaligned or separated, and the waterproof membrane will be separated from the slab due to shear force or internally broken due to tension, so that the building roof cannot meet the original design Waterproof requirements, this phenomenon is especially common in coastal areas with strong typhoons or in the area affected by the vibration of railway trains

[0013] 3. The waterproof membrane is pasted with the concrete leveling layer with an adhesive. The aging period of the adhesive is often shorter than that of the waterproof membrane. When the waterproof membrane is within the normal service life, the adhesive has aged and failed. As a result, the entire waterproof layer is laid empty on the roof, and a leaking water channel is formed between the waterproof layer and the roof. The sky slab is soaked in water for a long time and eventually causes the slab to rot or even fall off. The waterproof function cannot be realized, and the safety of the building cannot be guaranteed. Assure

[0014] How to eliminate and solve the above-mentioned problems is one of the common research topics in this field, but so far, no research results to solve the above-mentioned problems have been seen.
