Referring to fig. 1, one surface of the outer cement mortar 72 is sequentially provided with a waterproof roll 74, an isolation layer, and a fine stone concrete protection layer 75. In this embodiment, the waterproof sheet 74 is a SBS waterproof sheet 74 with a thickness of 3+3mm, which is a sheet-like waterproof sheet 74 that can be rolled and is made of asphalt using styrene-butadiene-styrene (SBS) thermoplastic elastomer as modifier as impregnating and coating material, and the upper surface of the sheet-like waterproof sheet is covered with polyethylene film, fine sand, mineral sheet (granule) material or aluminum foil, copper foil or other isolation material. The isolation layer adopts the polyethylene film of 0.4mm thick, and the thickness of pea gravel concrete protective layer 75 is 40 mm. The isolation layer sets up between waterproofing membrane 74 and fine aggregate concrete protective layer 75, can effectual protection waterproofing membrane 74 not damaged by fine aggregate concrete protective layer 75, and waterproofing membrane 74 self has further improved the waterproof performance of roofing simultaneously.
The side of the fine stone concrete protective layer 75 facing away from the insulation layer is provided with a reinforced concrete bottom plate 76 and a drainage layer 77 which are both 100mm thick and have the same thickness. Drainage blanket 77 can tentatively discharge the processing to the rainwater on the roofing, and in reinforced concrete bottom plate 76 can completely cut off moisture and enter into pea gravel concrete protective layer 75, the effectual structural strength who increases the building.
The implementation principle of the embodiment is as follows: a water stop 46 is added to the upper portion of the deformation joint 3 so that moisture is not easily discharged from below the deformation joint 3, and a center plate 42 made of an aluminum alloy material and an upper metal frame 41 are covered above the water stop 46 and then fixed by expansion bolts and a first elastic rubber band. On the one hand, the waterproof performance of the building structure is improved, on the other hand, the integral roof structure is smooth in surface, and meanwhile, the metal frame and the central plate are connected with the first wall and the second wall, so that the structural strength of the roof is improved, and the anti-seismic performance is improved.
Elasticity kink forms the U-shaped rivers passageway that supplies the rainwater circulation, and waterproof portion has further increased the waterproof performance of movement joint down, and original protrusion has been eliminated with outermost plastic surface course of second wall body and reinforced concrete slab to first wall body simultaneously, has improved the smoothness nature of roofing drainage. The deformation joint is arranged to result in the loss of the strength of the building structure to a certain extent, the reinforcing plate effectively compensates the loss of the structural strength, and the anti-seismic performance and the service life of the reinforcing plate are improved.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
