Building drain pipe

Technical Field

The utility model relates to the field of pipeline tools, in particular to a building drain pipe.

Background

Noise and vibration are important factors affecting the health of the living environment, and with technological progress and importance of the living health elements, the improvement of the building acoustic environment is required to get more attention of society and users. The 3A high-requirement houses, green buildings, healthy houses, ecological buildings and the like all provide index control requirements for the building acoustic environment, but in the implementation link, the design and construction implementation of the building acoustic environment also lack corresponding technical support. For example, in the case of pipeline drainage noise, in the case of common three-room two-room and four-room two-room, due to irregular water drainage of a toilet, bath drainage, washing drainage and the like, time distribution is scattered and frequent, and drainage noise and pipe vibration exceed design control indexes, so that the living of adjacent households is influenced. The light pipe used in large quantity on site replaces the traditional cast iron water pipe, the drainage noise disturbance is increasingly serious, and the development of a pipeline sound insulation construction method and a construction technology which meet the sound insulation environment-friendly requirement is particularly necessary.

CN201593666U discloses a building sound insulation drain pipe, including inner tube (1) and cladding at the outer tube of inner tube (1), this outer tube is detained mutually by two semicircle pipes (2) and constitutes, semicircle pipe (2) inner wall sets up soundproof cotton (3). Although the sound insulation effect is achieved, the sound insulation device is simple in structure and easy to damage under the condition that hot water and cold water are frequently alternately flushed.

Disclosure of Invention

In order to overcome the defects in the prior art, the utility model provides the building drain pipe which has the structure capable of reducing noise, simultaneously playing the functions of heat insulation and heat dissipation, increasing the thickness, slowing down aging and prolonging the service life.

In order to achieve the aim of the utility model, the utility model adopts the following technical scheme:

a construction drain pipe comprising: the inner plastic layer, the first hot melt adhesive of inner plastic layer bonding, the first hot melt adhesive bonding is the steel wire net of cross structure, the steel wire net is through the outer plastic layer of two bonding of hot melt adhesive, the inner plastic layer inner wall is the arc in protruding along drain pipe length direction integrated into one piece connection, evenly be equipped with the through-hole along drain pipe length direction between inner plastic layer and the outer plastic layer, outer plastic layer lateral wall integrated into one piece connects the outer arch of T font, and is equipped with semi-circular outer arch between the outer arch of adjacent T font.

Compared with the prior art, the utility model has the advantages that: through arch and through-hole in the arc structure, when its structure effectively plays the noise reduction, the protruding and semi-circular protruding function of heat insulation and heat dissipation outward of adjacent T font, interior plastic layer bonding hot melt adhesive one, hot melt adhesive one bond be the wire net of cross structure, the wire net increases its thickness through hot melt adhesive two bonding outer plastic layers, slows down ageing and increase life.

As an improvement, the inner plastic layer, the first hot melt adhesive, the steel wire mesh, the second hot melt adhesive and the outer plastic layer are integrally formed. The double-layer structure and the through holes between the double-layer structure play a role in silencing.

As an improvement, the other end of the inner bulge is in a tip structure. The sound brought by water flow can be effectively reduced.

As an improvement, a gap is arranged between the semicircular outer bulge and the T-shaped outer bulge and is fixedly connected, and the semicircular outer bulge and the outer plastic layer are integrally formed; the side surface of the middle part of the T-shaped outer bulge is of a slope surface structure. And the heat dissipation and silencing effects are improved.
