Construction method of water-stop wall for ground toilet with low-temperature hot water radiant heating

Abstract

The invention belongs to the technical field of building construction, and particularly relates to a construction method for a seepproof screen of a low-temperature hot water radiant heating floor toilet. The construction method comprises the following steps that the seepproof screen and a ground leveling layer of floor heating of an adjacent non-water room are constructed, the base layer of an upstream face of the seepproof screen is processed, the upstream face of the seepproof screen is painted with cement-based permeation crystalline waterproof paint, the pipe root, penetrating through the seepproof screen, of a floor heating pipe is wrapped and pasted with waterproof rolls, waterproof rolls are pasted to the upstream face of the seepproof screen, a protective layer of the rolls of the upstream face of the seepproof screen is constructed, and a closed water test of the seepproof screen is carried out. According to the construction method, the process design is novel, operation is easy to conduct, the application range is wide, operation can be carried out with water and wet, and the waterproof effect is good.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction method for a water-stop wall of a ground toilet with low-temperature hot water radiation heating. Background technique [0002] With the rapid development of the national economy and the continuous improvement of the living standards of urban people, people have higher requirements for the quality of the indoor environment, that is, fresh and hygienic air, comfortable and pleasant temperature, etc., coupled with the adjustment of energy structure, building energy conservation and household With the implementation of the metered heating charging system, a new heating method - low-temperature hot water ground radiation heating was born. This technology was born abroad in the 1930s and 1940s and rose in the 1970s. However, my country only introduced this technology in the 1980s. With the development of the technology of "replacing steel with...

Problems solved by technology

[0003] However, due to the many procedures and complex structure of the low-temperature hot water ground radiant heating system, the national, industrial and local standards are not yet clear about some detailed methods

For example: in the design of low-temperature hot water ground radiant heating system, two waterproof layers are required to be designed in the room with water, respectively on the structural layer and the fine stone concrete filling layer on the ground heating floor. If the circle is crossed, it is necessary to set up a water-stop wall at the door stack, and the water separator and water collector are usually installed in a room with water such as the bathroom. In addition to the original PPR cold and hot water pipes, it usually results in the door stack of the bathroom. The dense pipelines bring great difficulty to the construction of the water-stop wall. If there is a little carelessness, there will be leakage from the room with water to the adjacent room.
