Embodiment 1

[0038] Embodiment 1, structure 1, uses a flexible flashing belt for waterproofing.

[0039] The working principle of the waterproof and breathable membrane is that in the state of water vapor, the water molecule clusters are very small. According to the principle of capillary movement, they can penetrate to the other side. When the water vapor condenses into water droplets, the particles become larger, and under the action of tension Under the environment, the water molecules can not be separated from the water droplets for reverse osmosis, which plays the role of breathability and waterproof.

[0040] At present, the internationally popular waterproof and breathable membrane is composed of polypropylene fabric + polymer breathable membrane + grid reinforcement + polypropylene fabric, which has been widely used in external wall insulation systems to improve the performance of the insulation system. This embodiment is aimed at the anti-flooding treatment of the overlapping join...

Embodiment 2

[0045] Embodiment two, such as figure 2 , the following takes the waterproof treatment of the flooding structure at the pipe outlet on the wall as an example to illustrate:

[0046] In the roof, a waterproof casing 51 is provided, and an insulating layer 52 and an outer decorative surface 53 are provided on the roof surface, and the flashing belt 1' is used at the lap joint between the waterproof casing 51 and the wall 5 When using this flashing belt, because the spunbonded olefin film has wrinkles, it can form effective stretching, and can be deformed to adapt to the shape of the waterproof casing to achieve the purpose of waterproofing.

[0047] In fact, in large-scale public buildings and civil buildings, thermal insulation treatment is required, and this structure is suitable for all, and does not affect the subsequent setting and treatment of thermal insulation layer construction.

[0048] The flexible flashing belt used in the above two embodiments is described below: ...

Embodiment 3

[0056] Embodiment three, such as figure 1 with figure 2 As shown, the structure is the same as that of Embodiment 1 and Embodiment 2, the difference lies in the difference in material selection and construction process.

[0057] The waterproof coiled material in the prior art used in the flashing belt adopts splicing to treat the parts to be treated. Waterproof membrane is a rollable sheet waterproof material. According to its main waterproof composition materials, it can be divided into three categories: asphalt waterproof material, polymer modified waterproof membrane and synthetic polymer waterproof membrane (SBC120 polyethylene polypropylene fiber composite membrane). There are PVC, EVA, PE, ECB and other waterproof membranes. Commonly used construction techniques are adhesive fixing method construction and heating heat sealing construction.

Abstract

The invention discloses a waterproof joint structure for a door / window hole. The waterproof joint structure comprises a building main body, a component, a flashing belt and a sealant, wherein a hole for mounting the component, the flashing belt and the sealant are arranged on the building main body; the flashing belt is attached to an overlapping part of the hole and the component, and the overlapping boundary of the hole and the component is completely covered by the flashing belt; a heat-preservation layer and a decorative layer are sequentially arranged on the outer sides of the flashing belt and the building main body; the sealant is adhered to a gap between the decorative layer and the component. According to the waterproof joint structure, by virtue of double-effect treatment of the flashing belt and the sealant, optimal waterproof effects are achieved; the flashing belt has the characteristics of excellent aging resistance, persistent adhesion, excellent stretching ductility, convenience in construction and capability of effectively preventing water leakage and seepage, and the problems of non-ideal using effects of a rigid flashing plate for a wall body hole and a component part and difficulty in the use of the rigid flashing plate are solved.

Description

technical field [0001] The invention relates to the joints for waterproofing engineering on the external wall doors and windows of buildings, wall openings, wall pipes and other parts, which can achieve a better waterproof effect. Background technique [0002] With the development of buildings, people have put forward higher requirements for the quality of living room construction and the anti-flooding and anti-leakage of construction projects. For example, in the existing exterior door and window projects (especially in large-scale curtain wall projects), the gap between the door and window frame and the wall is waterproofed with foamed polyurethane and sealant, but due to the different sizes of the gaps, foaming Polyurethane is not easy to completely fill the gaps, and the sealant is easy to age, so the long-term waterproof effect cannot be achieved, resulting in leakage at the doors and windows, which is inconvenient for later maintenance and cannot fundamentally solve th...
