Overall rigid waterproof system of building

Abstract

The invention discloses an overall waterproof system of a rigid building. The overall waterproof system comprises a gutter waterproof unit, a parapet wall waterproof unit, a ridge waterproof unit, a gable edge waterproof unit, a roof panel, a wall panel, a roof purline, a heat insulation layer and the like. A gutter in the waterproof system is not directly connected with the roof purline, and the gutter has a slope, so that the problems of poor heat insulation performance, many cold bridges, water accumulation in the gutter and the like due to direct connection of the gutter and the gutter supporting beam in the prior art are thoroughly solved; through inner and outer flashing pieces, a flashing conversion piece, a ridge water blocking plate and the like in the waterproof system, the mode of spreading sealant and then performing direct connection through tensioned rivets is changed into indirect connection, so the problem of water leakage on the roof due to ageing of daub is thoroughly solved, and the waterproof performance of a light steel colored plate building is greatly improved; and because of a sliding bracket, a building main body and accessories are connected tightly and firmly and can slide relatively, and the service life of the gutter is greatly prolonged.

Description

technical field [0001] The present invention relates to an integral rigid waterproof system for buildings, in particular to an integral rigid waterproof system for indoor gutters, roof ridges, gable sides, or parapet tops and under parapets and other building units of steel structures or light steel color plate buildings. . Background technique [0002] Steel structures and light steel structures have been widely used in various civil buildings, industrial plants, cold storages, workshops, exhibition halls and other buildings. In general, the roofs of buildings are designed in the shape of "herringbone" for drainage needs , while the roof of a large industrial factory building may be composed of multiple "herringbone" shapes. At this time, a gutter system should be installed at the intersection of the two "herringbone" shapes to drain the water in the middle of the roof; in addition, the gable is Architectural elements, with the needs of people's aesthetics and market econo...

AI Technical Summary

Problems solved by technology

[0004] One is water leakage at the roof ridge joints: the existing technology is to lay cement under the plug board first, and then use rivets or self-tapping screws to directly fix the plug board on the roof panel, which will easily cause the cement at the nail hole to age and leak And winter snow is blown into the roof ridge from both sides of the plug plate with the wind, and after melting, it enters the room and causes roof leakage;

[0005] The second is water leakage at the gutter joints: the steel plate gutter of the prior art is located on two symmetrical C-shaped steel gutter joists, the steel plate gutter is connected to the metal roof panels on both sides of the gutter, and the C-shaped steel gutter The gutter joist is directly connected with the steel plate gutter, and the indoor heat will be transferred to the gutter joist through the steel frame beam, and then transferred to the steel gutter by the gutter joist. When the indoor temperature and humidity reach a certain level, the gutter or C The bottom of the steel joist will cause condensation, water dripping, and heat loss on the indoor roof in winter, which will affect the indoor temperature effect; in addition, because the gutter joist is placed in a horizontal state, there is no slope on the gutter, and water is easy to accumulate in the middle of the gutter , It is easy to cause the gutter to rust, shorten the service life of the gutter, and also shorten the service life of the building itself;

[0006] The third is water leakage at the top node of the parapet wall: when the inner and outer flashing boards at the top of the parapet wall in the prior art are overlapped and connected at the top, they are all laid with full-length sealant or cement, and then connected with pull rivets. Finally, it often becomes a fatal water leakage point;

[0007] The fourth is water leakage at the node under the parapet wall: in the prior art, when installing flashing boards and auxiliary flashing parts on the metal roof panel under the parapet wall, the flashing parts are connected to the gable support angle steel, and then the daughter wall is installed on the upper end of the gable support angle steel. The inner side of the wall is sealed and fixed with self-tapping screws. Since the flashing parts and the side-span metal roof panels are covered with sealing tape or cement, and are connected by suture nails or rivets, when the sealing tape or cement ages, a large amount of The nail holes in the metal roof become fatal water leakage points, and the auxiliary flashing parts are also directly connected to the roof panel, which increases the chance of water leakage on the metal roof panel. The plates are pressed tightly, and the relative sliding between them is uncertain. For example, during construction, the self-tapping screws that fix the inner sealing plate of the parapet wall are often fixed on the gable support angle steel. Therefore, it is easy to cause the connection hole here. torn and leaking

[0008] To sum up, in the prior art, waterproof parts such as ridge plug boards, flashing boards, and gutters are directly connected to the roof panels, and only flexible waterproof materials such as cement are used to plug leaks, and the flexible waterproof materials are easily aging materials. Although the technicians in the industry are constantly working on improving the aging resistance of the sealant, the longest can only reach 5 to 8 years at present, while the life of steel structures and light steel color plate buildings can reach 50 to 70 years. Therefore, the use of flexible waterproof materials greatly shortens the service life of the building
