Fixation and encapsulation construction method and structure of water roof splicing seam with cantilever structure

Abstract

The invention discloses a fixation and encapsulation construction method and structure of a water roof splicing seam with a cantilever structure. An n-shaped fixation and encapsulation wall and waterproof anti-knock measures adopted in the wall form a first waterproof fixation and encapsulation structure, left and right water retaining walls and a waterproof anti-knock measures adopted in the walls form a second waterproof fixation and encapsulation structure, an original structure of a water roof carvel joint with the cantilever structure is well combined and used, seal fixing structure extension is carried out, a main water roof and a cantilever roof are subjected to integrated waterproof fixation and encapsulation, integration is high, the structure intensity is high, the impact resisting and vibration resisting properties are good, the good resonance adaptation is achieved, damage to the fixation and encapsulation structure due to vibration is avoided, draining is carried out whileseal water prevention is carried out, long-time water accumulation is prevented, the method and structure do not excessively depend on macromolecule waterproof materials, even if the macromolecule waterproof material fails due to aging, the good waterproof effect is still achieved, the service life is long, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to a waterproof sealing technology for roof joints, in particular to a construction method and structure for sealing joints of a water-engaged roof with a cantilever structure. Background technique [0002] The joints of water-filled roofs, especially the flat joints of water-filled roofs with cantilevered structures such as flat-roofed shops, in order to avoid leakage caused by water or accumulated water, the traditional sealing methods generally include There are two types, one is to cover the seams with the metal joint cover and waterproof sealing polymer adhesive material. The advantage of this method is that the construction is simple and the construction efficiency is high. However, in the joint If the joints are not disturbed or impacted, the effect is acceptable. Under harsh conditions such as long-term water storage, vibration, storm impact, and long-term high-temperature sunlight, the polymer material bonding material wi...

[0002] The joints of water-filled roofs, especially the flat joints of water-filled roofs with cantilevered structures such as flat-roofed shops, in order to avoid leakage caused by water or accumulated water, the traditional sealing methods generally include There are two types, one is to cover the seams with the metal joint cover and waterproof sealing polymer adhesive material. The advantage of this method is that the construction is simple and the construction efficiency is high. However, in the joint If the joints are not disturbed or impacted, the effect is acceptable. Under harsh conditions such as long-term water storage, vibration, storm impact, and long-term high-temperature sunlight, the polymer material bonding material will be aged. Failure, tearing and water seepage of the connection layer between the metal cover and the roof, and insufficient strength of the connection and sealing structure will affect the waterproof effect and the life of the sealing; the other is to cover it with concrete after laying a waterproof layer of polymer materials. , this kind of structure also has the situation that the structure is easy to be torn under vibration. Once a crack appears, it is bound to be prone to water seepage in the crack, and it will get worse and worse day by day

Moreover, since there is generally a roof enclosure structure between the overhanging structure and the flooded roof, no matter whether it is metal cover plate sealing or concrete filling, it is difficult to achieve integration, so the main flooded roof and the overhanging roof need to be separated If waterproof and solid-sealed construction is carried out, then the overall stability of the solid-sealed structure will be worse, and problems will occur more easily.

All in all, the traditional sealing method and structure of the flat joints of the cantilevered roof have disadvantages such as poor integrity, short service life, and poor shock and vibration resistance.
