Abstract
The utility model provides a self-support type fire-resistant ventilation duct structure comprising a hoisting rod, section steel and a wall body, wherein, a ventilation duct consists of a plurality of baud plate pipelines connected through baud plate joint strips, L-shaped lightgage steel joists and self-tapping screws therebetween, and the baud plate pipelines are fixed on the wall body through the section steel and the hoisting rod after being connected. The duct, which is made up of baud plates in the above manner, not only is excellent at resisting fire, but also can be used as an air supply duct, due to relatively low heat conductivity of baud plates, to effectively reduce energy loss, thereby achieving the purpose of saving energy. The utility model facilitates construction, is resistant to moisture, avoids emitting harmful gases in case of fire, and is simple to install and long in service life.
Description
Technical field:
The utility model relates to the ventilation equipment technical field, refers in particular to a kind of self supporting type fire prevention ventilation shaft structure.
Background technology:
Present ventilation shaft all is by the iron sheet airduct, sprayed fire proofing coats with lacquer on airduct then, the fire protecting performance of this kind pipeline directly is subjected to the influence of fire resistant coating spraying thickness, and fireproof paint is oil paint, non-environment-friendly products, iron pipeline gets rusty easily, greatly reduce the service life of pipeline, and iron plate also is combustion-supporting material when fire, coating can distribute pernicious gas when fire, jeopardize the crowd
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of self supporting type fire prevention ventilation shaft structure of being made by the baud plate is provided.
For achieving the above object, technical scheme provided by the utility model is: a kind of self supporting type fire prevention ventilation shaft structure, it includes suspension rod, shaped steel, body of wall, ventilation shaft is by connecting to form by baud plate seam lath, L type lightgage steel joist and tapping screw between a plurality of baud plate pipelines, and the baud plate pipeline after the connection is fixed on the body of wall by shaped steel and suspension rod.
The rectangular duct that described baud plate pipeline is made up of polylith baud plate, rectangular duct inside lock place is provided with L type lightgage steel joist, and the baud plate is fixed on the L type lightgage steel joist by tapping screw.
Connection seam crossing between the described baud plate pipeline is provided with L type lightgage steel joist, and L type lightgage steel joist is provided with baud plate seam lath outward, and tapping screw connects baud plate seam lath, L type lightgage steel joist, baud plate pipeline successively.
Described baud plate pipeline is installed on the shaped steel, and shaped steel is fixed on the suspension rod, and suspension rod is fixed on the body of wall by dilating screw.
After having adopted said structure, the pipeline that the baud plate is made not only has good fire line, and because the thermal conductivity factor of baud plate is lower; As air supply duct, can effectively reduce the loss of energy, reach purpose of energy saving, and easy construction, quick, and moisture resistance, water-fast, can not produce pernicious gas during fire, long service life is installed simply.
Description of drawings:
Fig. 1 is the utility model airduct structural representation.
Fig. 2 is an A place cutaway view among Fig. 1.
Reference numeral: 1-suspension rod, 2-shaped steel, 3-dilating screw, 4-body of wall, 5-L type lightgage steel joist, 6-baud plate, 7-tapping screw, 8-baud plate pipeline, 9-baud plate seam lath.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing 1 and accompanying drawing 2, preferred embodiment of the present utility model is: the main a kind of self supporting type fire prevention ventilation shaft structure that is made by the baud plate, it includes suspension rod 1, shaped steel 2, body of wall 4, ventilation shaft is by passing through baud plate seam lath 9 between a plurality of baud plate pipelines 8, L type lightgage steel joist 5 and tapping screw 7 connect to form, wherein, the rectangular duct that baud plate pipeline 8 is made up of polylith baud plate 6, rectangular duct inside lock place is provided with L type lightgage steel joist 5, baud plate 6 is fixed on the L type lightgage steel joist 5 by tapping screw 7, baud plate 6 mainly is to be made by silicate, and very strong fire prevention is arranged, moisture resistance, water-fast function; Connection seam crossing between the baud plate pipeline 8 is provided with L type lightgage steel joist 5, is provided with baud plate seam lath 9 outside the L type lightgage steel joist 5, and tapping screw 7 connects baud plate seam lath 9, L type lightgage steel joist 5, baud plate pipeline 8 successively.Baud plate pipeline 8 after the connection is installed on the shaped steel 2, and shaped steel 2 is fixed on the suspension rod 1, and suspension rod 1 is fixed on the body of wall 4 by dilating screw 3; After having adopted the baud plate, mounting process is simple, only need lay down tapping screw 7 in the time of change and get final product, safeguard very convenient, long service life.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the variation that all shapes according to the utility model, principle are done all should be covered by in the protection domain of the present utility model.
