Abstract

A damp insulation method for a hollow terrace, a wall and a column of underground engineering relates to an indoor waterproof and damp insulation structure of the underground engineering. When the concrete terrace is connected with the structural wall and the structural column, the accumulated water at the wall root bottom is led to the concrete terrace along the capillary action of the wall surface, and the connection part of the terrace, the wall and the column is wet. To solve these problems: firstly, the side surfaces of the wall and the column are fully adhered with a drainage lath, the side surfaces of the wall and the column are fixed by steel nails or adhesive tapes, then the drainage plate of the bottom plate is propped against the drainage plate of the side surfaces, a concrete surface layer is poured and tamped on the drainage plate of the bottom plate to form a hollow terrace with the drainage plates on the bottom surface and the side surfaces, so that the hollow terrace is separated from the structural wall and the column to achieve the damp-proof effect, and the inner surface of the basement is free of water seepage and moisture for a long time.

Description

Moisture insulation method for hollow terrace, wall and column of underground engineering

One, the technical field

The invention discloses a damp-proof method for floors, walls and columns of underground engineering, and relates to an indoor waterproof and damp-proof structure of the underground engineering.

Second, background Art

The invention provides a method for manufacturing an indoor hollow layer of an underground engineering, which is a series of continuously improved inventions and creations, mainly focuses on the overall plane quality of a plastic drainage plate, and lacks of a matched measure when a concrete terrace is connected with a structural wall and a structural column, so that accumulated water at the bottom of the wall is led to the concrete terrace along the capillary action of the wall surface, and the connection part of the terrace with the wall and the column is wet.

Third, the invention

The method comprises the steps of firstly, fully attaching a drainage batten with a fulcrum of 10-30 mm to the side surface of a wall or a column, fixing the drainage batten with a steel nail or an adhesive tape, then propping a drainage plate on the side surface with a bottom plate, pouring and tamping a concrete surface layer on the drainage plate on the bottom plate to form a hollow terrace with the drainage plate on the bottom surface and the side surface, and separating the hollow terrace from the structural wall or the column to achieve the moisture insulation effect. When the side drainage plate is lower than the concrete terrace, a foaming glue is arranged at the top end of the side drainage plate to seal a gap layer between the drainage plate and the wall surface, and then the terrace concrete is poured. When the side drainage plate is higher than the concrete terrace, after the concrete terrace reaches the strength, the drainage plate higher than the ground is cut flat, and the floor surface coating is made to seal the gap of the side drainage plate. When the side drainage plate is higher than the concrete terrace and the structural wall surface needs to be led, drained water, the drainage plate is paved upwards, fixed by the plastic keel and the expansion bolt, and cement mortar is coated to form hollow mortar coating, so that the gap layer is connected to the structural bottom plate surface.

Although the side drainage plate is arranged close to the structural bottom plate, the gap of the side surface is communicated with the gap of the bottom surface due to the unevenness on the plate surface, so that seepage water can flow out. The hollow layer is used for breaking the transmission of the capillary action, so that the detailed problem of the engineering quality is solved, and the inner surface of the basement is free of water seepage and moisture for a long time.

Description of the drawings

Fig. 1 is a cross-sectional view of a hollow floor, with drainage plates on both the bottom and sides.

Fig. 2 is a cross-sectional view of a hollow floor with a floor surface coating closing the side drainage plate voids.

FIG. 3 is a cross-sectional view of a hollow floor, and a foam rubber strip is sealed at the top end of a side drainage plate.

FIG. 4 is a cross-sectional view of a hollow floor, which is then extended upward to render a hollow wall.

Fifthly, specific implementation method

As can be seen from figure 1, a side drainage plate 3 is firstly paved on the surface 2 of a structural wall or a structural column, then a drainage plate 4 on a structural bottom plate 1 is propped against the side drainage plate 3, and then a concrete surface layer 5 is poured to form the hollow concrete terrace with the drainage plates on the bottom surface and the side surface.

The side drain bar 3 of figure 2 is higher than the concrete terrace 5, after the concrete terrace reaches intensity, cuts out the drain bar 3 flat, when making terrace surface coating 6, closes the space of side drain bar again.

The side drainage plate 3 of fig. 3 is lower than the concrete terrace 5, so the top end of the drainage plate 3 is firstly drilled with a foaming adhesive 7 to close the gap layer, and then the concrete terrace 5 is poured.

The side drainage plate 3 of fig. 4 is higher than the terrace 5, and then the drainage plate 8 is extended upwards, the keel and the drainage plate 8 are fixed by the plastic keel 9 and the expansion bolt 10, and then the surface painting 11 is made, so that the hollow mortar painting is formed.

Claims
