Embodiment Construction
[0014] Combined with the specific implementation of the project, the present invention is further described so that those skilled in the art can better understand the present invention, but the present invention is not limited thereby.
[0015] In the engineering design, the roof waterproofing is 3mm+3mm SBS modified bitumen waterproofing membrane, and the waterproofing protective layer of the membrane is 40mm thick C20 fine stone concrete protective layer, a method for anti-cracking and split-silo pouring of the roofing waterproofing protective layer. The specific implementation steps are as follows:
[0016] S100: After the waterproof construction of the roofing membrane is completed, apply a layer of cement:sand:special bonding interface agent on the waterproofing surface of the membrane with a ratio of 1:2:0.5.
[0017] S200: On the waterproof layer, according to the position of the roof rainwater pipe and the drainage slope, the interval is not more than 6m, and the positi...

The invention belongs to the technical field of roof waterproof construction, and particularly relates to an anti-cracking separated bin pouring method for a roof waterproof protection layer. Comprising the following steps that S100, after waterproof construction of the roof coiled material is completed, the waterproof surface of the coiled material is coated with a waterproof layer; s200, dividing the positions of dividing joints on the waterproof layer according to the positions of roof rainwater pipes and the drainage gradient and the distance not larger than 6 m, and popping up a control line; s300, waterproof strips are pasted to the positions of the separation seams, and the two sides of the separation seams are fixed by using cement mortar to form slopes; s400, after the waterproof strips are installed, mortar cakes are pasted in the divided lattices according to the thickness of a concrete protection layer and the drainage gradient, concrete pouring is carried out according to lattices, intervals and bins during concrete pouring, and concrete pouring is carried out twice; and S500, during concrete pouring, the anti-crack steel wire mesh is pressed internally, and after concrete pouring is completed, secondary surface finishing is conducted before initial setting, and surface cracks are eliminated. According to the method, cracks of the thin and fine aggregate concrete protective layer of the roof are effectively avoided.
Description
technical field [0001] The invention belongs to the technical field of roof waterproof construction, and in particular relates to a method for preventing cracking of a roof waterproof protective layer and pouring into separate warehouses. Background technique [0002] With the development of social economy and civilization, people's living demand for building products is also getting higher and higher. The construction quality of buildings is the foundation of enterprise survival. Quality control involves every construction process. The cracking of the stone concrete waterproof protective layer is also a common problem and difficulty in quality control. It is often caused by improper construction methods or lack of construction technology, causing concrete cracking, affecting the appearance, and serious roof leakage, causing certain economic losses to the top-level residents. and resulting in a series of conflicts. Solving the problem of cracks and cracks in the waterproof ...
