Description

Waterproof structure of roof deformation joint

Technical Field

The utility model relates to a roofing waterproof construction technique, concretely relates to waterproof construction of roofing movement joint.

Background

In the field of house construction, particularly residential projects, roof deformation joints are common, such as halls, roofs with no people on machine rooms, roofs with people on flat roofs, garage planting roofs and the like. The roof deformation joint has more structural forms, and the construction experience accumulation on site is also more, but generally speaking, the waterproof effect in the early stage of part deformation joint is better, and through artificial damage or improper protection of finished products, the waterproof structure durability is poorer, and the long-term waterproof effect does not reach the expectation. And part roofing waterproof structure process is loaded down with trivial details, and the detail is handled more, and the process quality is not in place to the accuse, influences whole water-proof effects easily. In addition, the deformation joint needs to consider the influence of factors such as temperature, foundation, earthquake and the like on the building, and the waterproof structure needs to consider the flexibility of the waterproof structure to ensure the free deformation of the buildings at the two sides of the deformation joint, so that the deformation joint is prevented from cracking and even being damaged to cause leakage.

a waterproof structure of a roof deformation joint comprises a concrete floor slab, wherein at least one deformation joint is arranged in the middle of the concrete floor slab, and the waterproof structure is characterized in that a left reverse ridge and a right reverse ridge are respectively arranged on the concrete floor slabs on the left side and the right side of the deformation joint, the left reverse ridge is higher than the right reverse ridge, foamed plastic is arranged between the left reverse ridge and the right reverse ridge, a horizontal cover plate which completely covers the left reverse ridge and the right reverse ridge is arranged on the left reverse ridge, and a side joint is formed between the horizontal cover plate and the top surface of the right reverse ridge; a rubber water stop belt with the top extending into the horizontal cover plate and poured in the horizontal cover plate is pre-buried in the right reversed bank, and the rubber water stop belt is arranged along the length direction of the right reversed bank; and plugging fillers for sealing the side seams are arranged in the side seams and on the outer sides of the rubber water stops. Therefore, the left reverse ridge and the right reverse ridge effectively raise the height of the concrete floor slab on two sides of the deformation joint, so that accumulated water at the concrete floor slab is prevented from flowing to the deformation joint preliminarily, and preliminary water prevention is formed; the side seam formed between the horizontal cover plate and the right reverse ridge can provide a deformation space for the concrete floor, so that the free deformation of buildings (structures) on two sides of the deformation seam is effectively ensured, and the leakage caused by the cracking and even the damage of the deformation seam is prevented; the deformation joint is completely shielded by the horizontal cover plate, the rubber waterstop and the right reverse ridge, so that rainwater is effectively prevented from entering the deformation joint; the plugging filler filled in the side seams can further improve the waterproof effect at the side seams and improve the durability of the waterproof structure at the deformation seams. The waterproof structure is simple in overall structure and convenient to construct.

Furthermore, a leveling layer and a waterproof layer are sequentially arranged on the upper end face of the concrete floor slab, the outer end faces of the left reverse ridge and the right reverse ridge from inside to outside, the waterproof layer of the left reverse ridge extends upwards, covers the horizontal cover plate, turns over downwards and extends into the inner side of the plugging filler, then continues to extend to the outer side of the right reverse ridge, and finally horizontally extends to the leveling layer of the concrete floor slab on the right side. Therefore, the arranged waterproof layer has no seam at the deformation joint, is integrally laid, and has good waterproof effect.

Further, a protective layer covering the waterproof layer is arranged on the waterproof layer, and the protective layer is made of cement mortar with the thickness of 15-25 mm. Like this, the protective layer can avoid the waterproof layer to expose outside, forms effective protection to the waterproof layer, simultaneously, can also increase the laminating degree between waterproof layer and the screed-coat.

Furthermore, the protective layer arranged on the horizontal cover plate is obliquely arranged towards the right reverse ridge direction, and the inclination of the inclination is 1.5% -2.5%. Like this, set up the slope back on horizontal apron, can effectively guide apron department rivers flow direction.

Furthermore, the leveling layer at the intersection of the concrete floor slab and the left and right reversed sills is a round angle, a waterproof additional layer is arranged at the round angle and between the waterproof layer and the leveling layer, and the width of the waterproof additional layer at the round angle is not less than 250 mm. Like this, waterproof layer corner rounding off inadequately can be avoided in the fillet part, avoids the fragile problem in waterproof layer corner, and waterproof additional layer can effectively increase the water-proof effects of waterproof layer corner, effectively promotes the firmness in waterproof layer corner.

Further, the waterproof additional layer is polyurethane type waterproof paint with the thickness of 1-1.5 mm. Therefore, the thickness of the waterproof layer is set properly, and the waterproof effect is good.

Further, the plugging filler comprises asphalt hemp threads arranged on the inner side and asphalt factice plugged on the outer side of the asphalt hemp threads. Therefore, the plugging filler is used for double plugging, and the waterproof effect is good.
