Abstract

The invention discloses a method for overlapping a high polymer self-adhesive film waterproof coiled material and a modified asphalt waterproof coiled material in vertical face. The base plate and the root of the outer wall are high polymer self-adhesive film waterproof coiled materials, and the outer wall is modified asphalt waterproof coiled materials, and the two coiled materials are connected by using a thermoplastic blind rivet belt because the two coiled materials cannot be directly connected. The free end of the high polymer self-adhesive film waterproof coiled material and the thermoplastic blind nail belt are tightly attached to the concrete outer wall together, the width of the thermoplastic blind nail belt is about 200mm, the long strip is provided with a through long groove, nail shooting holes are formed in the groove, and after the free end of the high polymer self-adhesive film waterproof coiled material and the thermoplastic blind nail belt are tightly attached to the concrete outer wall, nails are shot in the groove to fix the waterproof coiled material. The external wall modified asphalt waterproof coiled material is paved upwards from the lower part of the blind rivet belt by adopting a hot melting method (the blind rivet belt can be bonded with the modified asphalt waterproof coiled material when heated), and finally the lower part of the thermoplastic blind rivet belt is blocked by a sealing material. The method has simple operation method and good waterproof effect.

Description

Polymer self-adhesive film waterproof coiled material and modified asphalt waterproof coiled material elevation lap joint method Technical Field The invention relates to the field of basement outer wall waterproof construction, in particular to a waterproof coiled material with a base plate being a high polymer self-adhesive film, and an outer wall being a lap joint working condition of a modified asphalt waterproof coiled material. Background With the increasing of high-rise buildings and large public buildings and the requirement of space to underground, the basement and underground engineering are more and more, the underground waterproof engineering is more and more important, and whether underground waterproof is successful or not is not the basic requirement of the using function of the building or the structure, the structural safety and the service life of the building are affected to a certain extent, meanwhile, the investment can be saved, the engineering cost is reduced, and the maintenance is reduced. The high polymer self-adhesive film waterproof coiled material has the advantages of puncture recovery, weather resistance, self-healing, excellent physical properties and more stable chemical properties, is widely applied to the horizontal surface paving of underground waterproof engineering, but is rarely applied to the vertical surface of the underground engineering (such as a concrete outer wall). Most engineering design facades at the present stage are still modified asphalt waterproof coiled materials. The foundation slab is a macromolecule self-adhesive film waterproof coiled material, and the outer wall is a modified asphalt waterproof coiled material, which is unavoidable in engineering construction conditions. According to the lap joint method between two different coiled materials, at present, only the modified asphalt waterproof coiled materials are reserved upwards from the position of a foundation mat layer before the foundation mat is constructed, and the modified asphalt waterproof coiled materials are paved upwards along an outer wall after the foundation mat is poured, so that the lap joint transition of the waterproof coiled materials with two different materials is realized. The construction method has good waterproof effect, but if the modified asphalt waterproof coiled material is not reserved in advance during construction, the construction problem that the high polymer self-adhesive film waterproof coiled material and the modified asphalt waterproof coiled material cannot be overlapped during waterproof construction of the basement outer wall is faced. In order to make up for the defects of the prior art, the invention discloses a method for overlapping a polymer self-adhesive film waterproof coiled material and a modified asphalt waterproof coiled material in a vertical plane. The thermoplastic blind rivet belt is simple to process and customize, the rivet shooting and sealing materials are engineering general materials, the operation method is simple, and the waterproof effect is good. Disclosure of Invention The technical problem that this patent was to solve is to the not enough of above-mentioned current construction method, and provides a polymer self-adhesive glued membrane waterproofing membrane and modified asphalt waterproofing membrane facade overlap joint method, and the technical scheme that this patent adopted is: Step 1, a thermoplastic blind rivet belt with the width of about 200mm is long and is provided with a through long groove, a rivet shooting hole is arranged in the groove, and the thermoplastic blind rivet belt can be well bonded with a hot-melt modified asphalt waterproof coiled material when heated; and 2, adhering the high polymer self-adhesive film waterproof coiled material expanded from the foundation base plate along the vertical face to a height of about 1000mm, and reserving a 150mm wide free end at the horizontal edge of the uppermost part. And 3, folding the free end of the 150mm wide polymer self-adhesive film waterproof roll, tightly attaching the outer side of the waterproof roll to the thermoplastic blind nail belt, and attaching the inner side of the free end to the concrete outer wall.
