Abstract

The utility model relates to a house fume removing and venting tube, belonging to the building material, and composed of a main air tube 1 and a side air tube 2 which are separated by a tube interlayer 6. The tube wall of the side air tube 2 is provided with a venting hole 3, and the upper part of the side air tube 2 is provided with a communicating opening communicated with the main air tube 1. The top of the main air tube 1 is provided with a tube neck 8. In installation, the bottom of the side air tube 2 is seated on a floor, and the top is close to a house ceiling. In the floor remain hole of the tube neck 8 of the main air tube 1, the main air tubes 1 of all floors are connected tail to end. The utility model has the advantages of low cost, convenient construction, high strength and small land occupation, can be built from a second floor or above, and is especially adapted to high buildings.

Description

House fume removing and ventilation pipe

The utility model belongs to constructional materials, is a kind of smoke-discharging and ventilating pipe.

The smoke evacuation in existing house, ventilating duct is built by laying bricks or stones with the common brick mortar, or use concreting, though this kind pipeline has solved house smoke-discharging and ventilating problem, construction is complicated, must begin to build by laying bricks or stones from first floor, it is big to take up room, and the situation of falling the cigarette often takes place the cost height, the department of construction in recent years adopts prefabricated pipeline to do air chimney, uses but be not suitable for highrise building.

The purpose of this utility model is to provide that a kind of to take floor space little, and quick construction conveniently can be used for high-rise building, does not need to do the flue basis, and cost is low, the smoke-discharging and ventilating pipe of reversing smoke free.

Solution of the present utility model is a kind of pipeline of being made by cement and glass fiber mesh of design.Pipeline is separated into air main and crosswind pipe by the pipeline interlayer, on the crosswind tube wall ventilation opening is arranged, and the connected entrance that is communicated with air main is arranged at crosswind pipe top, and the air main of each pipeline joins end to end, and forms the house smoke-discharging and ventilating pipe that is communicated with up and down.

Below in conjunction with accompanying drawing the utility model is specified:

Fig. 1 is the utility model schematic diagram;

Fig. 2 is the utility model cut-away view.

The utility model is by air main 1, crosswind pipe 2 constitutes, and has pipeline interlayer 6 to separate between air main 1 and the crosswind pipe 2, on crosswind pipe 2 tube walls ventilation opening 3 is arranged, the connected entrance 7 that is communicated with air main 1 is arranged at top, crosswind pipe 2 port closeds, air main 1 port open, neck 8 is arranged at the top of air main 1, air main 1, the tube wall 4 of crosswind pipe 2 and pipeline interlayer 6 is made by cement, and there is interlayer 5 centre, and interlayer 5 can adopt glass fiber mesh.The thickness of tube wall 4 is 0.8-1.5cm, can adopt M ₁₀Cement.The height of ventilation opening 3 can be determined according to specific requirement, can connect with the exhaust hood pipeline, is used for kitchen exhaust, grate also can be installed be used for the lavatory ventilation.This air chimney can be designed to an air main, and two crosswind pipes are used for the kitchen, the building that the lavatory is adjacent.The air chimney height is one deck building height, neck 8 height are identical with slab thickness, air chimney is installed when building the building, the bottom of crosswind pipe 2 is sitting on the floor, and the house ceiling is pressed close at the top, and the neck 8 of air main 2 is in the preformed hole of floor, air main 1 is end to end, constitute a cover air chimney of building, do not need to establish air chimney, can more than two layers or multilayer, begin to build air chimney as the building bottom.Because the interval of pipeline interlayer 6, the flue gas in the air main 1 can not seal in crosswind pipe 2.

The utility model is simple in structure, and cost is low, easy construction, and the intensity height, floor space is few.
