Problems solved by technology

[0004] -In the workshop manufacturing process, together with processes such as cutting and welding, several machines such as cutters, press brakes and sealing machines are used, making handling and forming expensive
[0005] -Once manufactured, storage, handling, road transport and delivery are costly due to large pipe cross-sections occupying a large volume
[0006] - Unloading, storage and on-site handling to point of installation is also expensive

Embodiment Construction

[0035] first reference Figure 1-4 In the illustrated embodiment, the tubular duct member of generally rectangular cross-section is assembled from first and second pairs of opposing generally flat steel sheet panels 10,10 and 12,12. Panels 10 and 12 are joined along adjacent longitudinal edges by mutually cooperating jaws 14 and 16 ("longitudinal" herein referring to the direction of fluid flow in the finished conduit). Jaw 14 through the image 3 The lateral extensions of a single steel sheet blank are folded in the manner shown to form along opposite edges of the panel 10, while the jaws 16 are formed by Figure 4 The lateral extensions of a single steel sheet blank are folded to form along opposite edges of the panel 12 in the manner shown. exist image 3 and 4 , the lettered area of ​​the blank corresponds to the similarly lettered portion of the folded panel. The panels 10 and 12 also include folded steel sheet end flanges 18 also formed from the blank shown. These ...

Abstract

A duct member comprising a plurality of sheet metal panels (10, 12) joined along adjacent longitudinal edges by cooperating folded sheet metal jaws (14, 16) which are pushed together so that Corresponding securing surfaces (28, 30) on each jaw engage each other to hold the edges of the sheet metal together. One (14) of the jaws includes a body (36) of resilient material that is compressed between the jaws and reversely biases the jaws to hold said securing surfaces (28, 30) in abutment against each other.

Description

technical field [0001] The present invention relates to a pipe member, ie a length of pipe joined end to end to form pipes for eg air and gas distribution systems. Background technique [0002] Typically, pipes are fabricated and assembled in workshops. They are then transported to site where they are combined with fittings such as reducers, tees, elbows, elbows etc. to form air and gas distribution systems. [0003] The disadvantages of existing products are: [0004] - In the workshop manufacturing process, together with processes such as cutting and welding, several machines such as cutters, press brakes and sealing machines are used, making handling and forming expensive. [0005] - Once manufactured, storage, handling, road transport and delivery costs are relatively high because of the large volumes occupied by the large pipe cross-sections. [0006] - Unloading, storage and on-site handling to the point of installation is also expensive. [0007] current technolog...
