Description

Variable cross-section type shear wall for high-rise residence and drainage vertical pipe thereof

Technical Field

The utility model relates to a high-rise residential engineering field especially relates to a high-rise residential variable cross section formula shear force wall and drainage riser thereof.

Background

In the design engineering in recent years, high-rise houses need increasingly compact household type, the size of toilets is small, and the problems that sanitary ware is compactly arranged and the position where a vertical drainage pipe can be installed is limited exist. Due to structural rigidity requirements and the like, shear walls are usually of a stepped variable cross-section design in hectometer high-rise buildings. When a traditional drainage vertical pipe passes through a floor slab and meets a variable cross section of a shear wall, a 45-degree Z-shaped elbow is usually arranged on the floor slab to perform transition treatment on the drainage vertical pipe.

The traditional installation mode of the vertical drainage pipe has the following problems:

1. the second elbow is 150-300 mm higher than the ground, and the use of the toilet is influenced.

2. Due to the specification and size of the second elbow (DN100 axial deviation of the second elbow is about 150mm), and the deviation size of the shear wall is generally 50-100 mm, the outer wall of the drainage vertical pipe on the variable cross-section layer is far away from the wall (about 150mm), so that the attractiveness and the use of a toilet are affected.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a high-rise residence variable cross section formula shear force wall and drainage riser thereof, the utility model discloses a realize like this:

a variable cross-section shear wall for high-rise buildings, comprising:

the wall body, the wall body is cascaded increase from top to bottom section thickness, the section thickness change department of wall body sets up the floor, the upper end of wall body is close to floor department sets up the recess.

Preferably, the groove is 500mm high and 200mm wide, and the groove depth of the groove is the same as the variable cross-section offset dimension of the wall body.

A high-rise building drainage riser is suitable for the variable cross-section type shear wall of the high-rise building, and comprises the following components:

the first flexible cast iron drain pipe is arranged above the floor and penetrates through the floor, a cast iron second-shaped elbow is arranged below the first flexible cast iron drain pipe, and a second flexible cast iron drain pipe is arranged below the cast iron second-shaped elbow.

set up in the floor top and run through the first PE drain pipe of floor, the below hot melt butt joint 22.5 second word elbow of first PE drain pipe, the below hot melt butt joint second PE drain pipe of 22.5 second word elbow, the top of 22.5 second word elbow sets up the fire collar, the fire collar is hugged closely the downside surface of floor.

The beneficial effects of the utility model reside in that:

1. the groove is formed in the upper end of the wall body close to the floor slab for abdicating, so that the mounting position of the second-shaped elbow is changed, the second-shaped elbow is prevented from protruding above the floor slab, the use space of a toilet is reduced, and meanwhile, the aesthetic feeling is increased.

2. A22.5-degree Z-shaped elbow is used in the PE pipe, and compared with a traditional 45-degree Z-shaped elbow, the PE pipe is better in flow guiding and water guiding capacity and better in drainage effect. Meanwhile, the fire-proof ring is additionally arranged, so that the fire-proof capability of the PE drain pipe is improved, and the potential safety hazard is reduced.
