Description
Technical Field
The invention relates to the technical field of waterproof structures, in particular to a waterproof structure for a basement exterior wall construction joint.
Background
A basement is a room whose floor is more than one-half of the net height of the room below the outdoor ground level. Multi-storey and high-rise buildings require a deeper foundation and to take advantage of this height, basements are built under the bottom floor of the building. The basement is built below the bottom layer of the house, so that the land efficiency of the building can be improved. Some high-rise building bases are buried deeply, basements are built by fully utilizing the depth, and the economic effect and the using effect are good. The basement is divided into common basements and emptying basements according to functions; according to the structural material, the concrete structure basement has a brick wall structure and a concrete structure basement, and according to the structural form, the concrete structure basement has a full basement and a half basement. The construction joint (construction joint) refers to a joint formed between the concrete poured before and after the concrete is poured in sections due to design requirements or construction requirements in the concrete pouring process. The construction joint is not a real existing joint, and only because the initial setting time of the first poured concrete is longer than the initial setting time, a joint surface exists between the first poured concrete and the later poured concrete, and the joint surface is called as the construction joint. At a construction joint, because the basement outer wall is in a short special geographical position and is easily corroded by external moisture, a waterproof structure is needed to reduce the corrosion of rainwater.
At present, chinese patent with publication number CN207348109U discloses a waterproof antiseep basement structure, and it includes basement structure body, basement structure body have concrete bottom surface and side wall, characterized by: be provided with the guiding gutter on concrete bottom surface, the setting of indoor floor drain, lower well or lighting shaft of guiding gutter slope, still be provided with half open-ended PVC pipe in the guiding gutter bottom, PVC pipe below the opening, behind the sealed gluey shutoff of gluing above the PVC pipe in the guiding gutter, the waterproof leaking stoppage of sealing glue layer upper portion reuse is precious floating, concrete bottom surface and side wall have the lower corner at handing-over position, the guiding gutter be close to and be on a parallel with the setting of lower corner department, concrete bottom surface and side wall on have one deck polymer waterproof mortar layer, concrete bottom surface and side wall on have one deck infiltration crystallization waterproof layer. Although the waterproof and anti-leakage basement structure has a good waterproof and anti-leakage effect, the waterproof effect of the polymer waterproof mortar layer is not high, if the polymer waterproof mortar layer is gradually eroded due to long-term rain erosion, the waterproof effect is lost, and the problem needs to be solved urgently.
