Abstract
The utility model discloses a section connecting structure of a super wide air duct; the air duct adopts a bucket structure with the square cross section, and the air duct is jointly connected section by section; the corresponding air duct wall connecting structure of two adjacent air ducts is that the inside and outside of the air duct wall are provided with a connection steel plate respectively and the two connection steel plates clamp the corresponding air duct wall of the two adjacent air ducts and are fixedly connected with the corresponding air duct walls of the two adjacent air ducts respectively; soft polytetrafluoroethylene (PTFE) is arranged and bonded between the connection steel plate and the air duct wall. The connecting structure between the sections of the air duct adopts flexible connection which is very simple, the construction is simple and the cost is low; the soft polytetrafluoroethylene (PTFE) is adopted as the sealing material between the air duct wall and the connection steel plate, thus the sealing effect is achieved while the strength requirement is also obtained.
Description
Technical field
The utility model belongs to the syndeton of ultra-wide steel plate wind pipe, is specifically related to the structure that the airduct segmentation connects.
Background technology
In recent years, on the airport, the occasion that needs to carry a large amount of air such as conference and exhibition center, gymnasium, powerhouse of hydropower station, the application of heavy in section airduct increases day by day, but in design and work progress, do not have corresponding reference frame, main dependence experience and the simple theoretical selection that designs with relevant parameter of calculating, the safety coefficient of choosing under a lot of situations is excessive, causes the waste of material and energy consumption.
Ultra-wide steel plate wind pipe is because volume too greatly can't integral hoisting; Can only segmental hoisting, section with section between the sealing problem that is connected just need adequate solution.
Summary of the invention
The utility model provides a kind of super wide airduct to divide section connection structure at the deficiency of prior art, this syndeton easy construction, and good airproof performance, cost is low.
Below introduce structure of the present utility model in detail, a kind of super wide airduct divides section connection structure, described airduct is that its cross section of barrel-like structure is a square, this airduct is formed by connecting by one section one section, the wind pipe wall syndeton of two neighboring sections airduct correspondence is, respectively be provided with one inside and outside the described wind pipe wall and connect steel plate, these two connect the wind pipe wall that steel plate clamps described two neighboring sections airduct correspondence, and corresponding with this two neighboring sections airduct respectively wind pipe wall is fixedly connected; Connect between steel plate and the wind pipe wall soft polytetrafluoroethylene (PTFE) be set, described soft polytetrafluoroethylene (PTFE) be connected between steel plate and the wind pipe wall bonding.
Optimally, described two neighboring sections airduct has the wind pipe wall of four groups of correspondences, so the two neighboring sections airduct is provided with four groups of independently wind pipe wall syndetons.
The utility model has the advantages that the syndeton between airduct section of the present utility model and the section has adopted the mode that is flexible coupling very simple, its easy construction, cost is low.Wind pipe wall be connected between the steel plate with soft polytetrafluoroethylene (PTFE) as encapsulant, can play sealing function, can reach requirement of strength again.
Description of drawings
Figure of description 1 is a main cutaway view of the present utility model.
The specific embodiment
Below in conjunction with Figure of description utility model is done further to disclose.
Embodiment 1:
See also Figure of description, a kind of super wide airduct divides section connection structure, described airduct is that its cross section of barrel-like structure is a square, this airduct is formed by connecting by one section one section, wind pipe wall 1 syndeton of two neighboring sections airduct correspondence is, respectively be provided with one inside and outside the described wind pipe wall 1 and connect steel plate 2, these two connect the wind pipe wall 1 that steel plate clamps described two neighboring sections airduct correspondence, and corresponding with this two neighboring sections airduct respectively wind pipe wall is fixedly connected; Connect between steel plate and the wind pipe wall soft polytetrafluoroethylene (PTFE) 3 be set, described soft polytetrafluoroethylene (PTFE) be connected between steel plate and the wind pipe wall bonding.
Described two neighboring sections airduct has the wind pipe wall of four groups of correspondences, so the two neighboring sections airduct is provided with four groups of independently wind pipe wall syndetons.
Carry out insulation at the bottom of the crossbeam that its concrete construction method is junction between the adjacent airduct, and top pressing board and screw rod at the bottom of beam, have been reserved, each clamps two sections airduct upper ends with a wide connection steel plate of the thick 500mm of 5mm inside and outside the end face wind pipe wall of adjacent two sections airduct correspondences, fixes with nut.Connect and use the thick soft polytetrafluoroethylene (PTFE) of 5mm bonding between steel plate and the end face wind pipe wall, the effect of wear-resisting wiping when stretching to play sealing and airduct.The wide connection steel plate of two thick 500mm of 5mm of external application clamps in other three junction wind pipe walls of two neighboring sections airduct, uses bolting, and is middle bonding as encapsulant with the thick soft polytetrafluoroethylene (PTFE) of 5mm.
Claims (2)
1, a kind of super wide airduct divides section connection structure, described airduct is that its cross section of barrel-like structure is a square, this airduct is formed by connecting by one section one section, the wind pipe wall syndeton that it is characterized in that two neighboring sections airduct correspondence is, respectively be provided with one inside and outside the described wind pipe wall and connect steel plate, these two connect the wind pipe wall that steel plate clamps described two neighboring sections airduct correspondence, and corresponding with this two neighboring sections airduct respectively wind pipe wall is fixedly connected; Connect between steel plate and the wind pipe wall soft polytetrafluoroethylene (PTFE) be set, described soft polytetrafluoroethylene (PTFE) be connected between steel plate and the wind pipe wall bonding.
2, super wide airduct according to claim 1 divides section connection structure, it is characterized in that described two neighboring sections airduct has the wind pipe wall of four groups of correspondences, so the two neighboring sections airduct is provided with four groups of independently wind pipe wall syndetons.
