Abstract

The utility model discloses a light smoke exhaust pipeline, wherein the pipe wall of the smoke exhaust pipeline is formed by bonding three layers of materials; the inner layer and the outer layer are both light heat insulating materials, and the middle layer is fiberglass grinding cloth or steel wire gauze; the intersection surface of the pipeline is in a hollow square structure, four interior angles of the hollow square structure are chamfers, and are respectively embedded with a circular reinforcing steel bar with the diameter of 3.5mm-8mm. The light smoke exhaust pipeline has the advantages of simple structure, light weight and good shake-proof and crack-proof performance, and the heat insulating performance and pipeline water-proof performance are improved greatly, which reaches the national fire fighting standard requirement further.

Description

The lightweight smoke discharging pipe

Technical field

The utility model relates to a kind of building accessory, specifically is a kind of lightweight smoke discharging pipe.

Background technology

Smoke discharging pipe in the traditional architecture thing is to adopt cement and mortar to be made; if make the flue that meets the fire-fighting requirement; just must spread cement mortar and make its tube wall thickening; can make that so again the weight of whole smoke discharging pipe is very big; thereby make the carrying of highrise building have great hidden danger; and be not easy to manually operate at the scene; therefore; when construction; the workman can use inferior materials and turn out substandard goods usually, causes the tube wall of smoke discharging pipe thin excessively, ftractures easily when the back internal-external temperature difference of plastering is excessive; pipeline antiseepage ability is also poor, and protecting against shock intensity does not reach code requirement yet.

The utility model content

Technical problem to be solved in the utility model provides the lightweight smoke discharging pipe of a kind of cracking resistance, antivibration, insulation, good heat-insulation effect.

The utility model solves the problems of the technologies described above with following technical scheme: the tube wall of the utility model lightweight smoke discharging pipe is to be formed by the trilaminate material bonding, the inside and outside two-layer light heat insulation material that is, and middle one deck is glass fiber reticular cloth or gauze wire cloth.

The cross-sectional structure of described lightweight smoke discharging pipe is the square hollow structure, and its four angles are embedded with the circular reinforcing bar post that a diameter is 3.5mm～8mm respectively.

Four interior angles of described lightweight smoke discharging pipe are chamfering.

The utility model lightweight smoke discharging pipe has the following advantages:

1. the utility model is simple in structure, in light weight, and its proportion alleviates 40-50% than former traditional product, also alleviates its floor built-loading simultaneously.

2. thermal and insulating performance improves, and further reaches the NFA code requirement.

3. the pipeline waterproof performance improves.

4. pipeline antivibration, cracking resistance are good.

Description of drawings

Fig. 2 is the A-A cross section cross-sectional schematic of Fig. 1.

Fig. 3 is the D-D generalized section of Fig. 2.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As shown in drawings, be installed in and have the smoke evacuation interface 2 that connects smoke extracting tube on the tube wall of the smoke discharging pipe 1 between the adjacent two layers floor, this smoke evacuation interface 2 has certain distance apart from the top floor, the tube wall of smoke discharging pipe 1 is to be formed by the trilaminate material bonding, cladding material 5 and inner layer material 6 are light heat insulation material, and middle layer material 4 is glass fiber reticular cloth or gauze wire cloth; The cross-sectional structure of smoke discharging pipe 1 is the square hollow structure, and its four interior angles are chamfering, is embedded with the circular reinforcing bar post 3 that a diameter is 3.5mm～8mm respectively on four angles.

Described light heat insulation material can adopt perlitic blister light heat insulation material, also can adopt other light noninflammable material.

The utility model adopts inside and outside two-layer light heat insulation material to clip the glass fiber reticular cloth or the gauze wire cloth of middle one deck; can strengthen its tube wall impact strength; when thermal current contacts tube wall in the pipe; directly contact with the blister light heat insulation material; its heat insulating material is just brought into play its thermal resistance anti-flaming function; protect its tube wall to stablize effectively and do not caused cracking or carbonization by thermalization or burning, make pipeline protect this premises temperature stabilization effectively, more effectively fire preventing stretches.

The utility model lightweight smoke discharging pipe finished product in July 28 in 2010 Nikkei Guangxi Zhuang Autonomous Region product quality supervision and inspection institute carry out simple random sampling check, its presentation quality, size, vertically load, anti-soft impulse and fire endurance all comply with the national standard requirements.

Claims

1. lightweight smoke discharging pipe, the tube wall that it is characterized in that it are to be formed by the trilaminate material bonding, the inside and outside two-layer light heat insulation material that is, and middle one deck is glass fiber reticular cloth or gauze wire cloth.
