Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Depend on figure 1 It can be seen that when the plain concrete cushion layer 7 of the bottom plate has been poured and the waterproofing of the coiled material 5 has been done, the construction mix ratio made according to the moisture content of the materials on site is supplied by the concrete mixing station or mixed on site with ordinary macroporous concrete 1, and then the Ordinary macroporous concrete 1 is poured continuously on the surface of membrane waterproof 5 . The pouring thickness is properly selected within 100-150mm, mainly considering the local winter temperature and the degree to which the water content of the foundation is affected by seawater. Some, on the contrary, take a smaller one.

[0019] After 12 hours (final setting time) of ordinary macroporous concrete 1 pouring, steel bars can be installed thereon, and base plate impermeable concre...

Abstract

The invention relates to the field of construction engineering, in particular to a structure for preventing the cold penetration and the dewing of a basement base plate of a costal building and a construction method thereof. The structure mainly comprises a base plate plain concrete cushion, waterproof coiled materials, watertight concrete, shear wall watertight concrete, an outer shear wall insulating layer and a protection wall. The invention is characterized in that a layer of common hollow concrete is added between the basement base plate concrete and the waterproof coiled materials. By casting the common hollow concrete and adding the insulating layer to the basement base plate, the basement base plate concrete does not have the problems of cold penetration and dewing at a low outside air temperature. The invention expands the design idea for the field of the insulation of the basement base plate of the costal building, and provides an effective method for fundamentally solving the common quality troubles of the cold penetration and the dewing of the basement base plate in the construction industry, thereby allowing a construction enterprise or a using enterprise not to spend human resources, material resources and financial resources year after year in dealing with the problems. The invention has prominent economic benefits and combined revenues.

Description

Technical field: [0001] The invention relates to the field of construction engineering, in particular to a structure and a method for preventing basement floors of buildings facing the sea from being exposed to cold and dew condensation. technical background: [0002] For the basement projects of buildings facing the sea, heat preservation, anti-leakage and moisture-proof are important technical indicators and quality requirements. Hollow block insulation is used for external insulation and frame parts, but no matter in design or construction, the basement floor structure is not insulated. When the outside temperature is low, the freezing point of groundwater is very low due to the geological conditions near the sea, and the basement floor Concrete surfaces are prone to cold and condensation problems. After the project is put into use, under the premise of not destroying the concrete of the basement floor, no matter what measures are taken, this problem cannot be effectivel...
