Abstract
The utility model discloses a novel steel tube connecting way, which comprises an inner steel tube and an outer steel tube, wherein two inner steel tubes are arranged and respectively superposed with axes of the outer steel; one end of the inner steel tube is plugged in the outer steel tube and jointed in the same; the other end of the inner steel tube is connected with a flange; the external diameter of the flange is between the external diameter of the inner steel tube and the external diameter of the outer steel tube; cement paste is filled in a gap of a jointed section of the inner steel tube and the outer steel tube so as to form an expanding cement ring; and a sheath is covered at the connected position of the outer steel tube. The novel steel tube connecting way of the utility model has lower technical requirement to construction environment and operator and is convenient for construction; and the mounting time is greatly reduced; the inner steel tubes of the novel steel tube connecting way are connected by the flange; and the sheath is covered at the connected position of the outer steel tube so that the steel tube is beautiful in shape and smooth in connection.
Description
Technical field
The utility model relates to steel pipe linkage structure technical field, is specifically related to a kind of novel steel tube Placement.
Background technique
Welding and flange connection are mainly adopted in the connection of steel pipe at present.Welding is the method through heating, pressurization or both and usefulness; Two pipe fittings is produced the Placement that combines between atom; But when welding, localized hyperthermia can cause that stress concentrates and defective such as the deformation of member; And welding technique has higher requirements to operator's technology, and the existence of weld defects tends to influence node strength and fatigue behaviour; In addition, generally need suitable welding environment during welding operation, in the high-altitude and underwater operation inconvenience.It is that two pipe fittings is fixed on the flange plate that flange connects, and adds flange gasket between two flange plate, with bolton Connecting format together.But existing inner flange only can be owing to the connection between large diameter steel pipe, less than adopting inner flange to connect between the steel pipe of climbing in people's ability; Adopt the outward flange linkage structure, the outward flange of protrusion not only diminishes attractive in appearancely, and long-pending easily dirty, corrosion influences working life and safety.
Summary of the invention
To the deficiency of above-mentioned existing technology, the purpose of the utility model is to make steel pipe to connect not only easy construction but also can influence the steel pipe outer aesthetic, and a kind of novel steel tube Placement is provided.
The technological scheme of the utility model is: a kind of novel steel tube Placement; Steel pipe and outer steel pipe in comprising; Steel pipe has two in said, and respectively with said outer steel pipe dead in line, said interior steel pipe one end inserts in the said outer steel pipe and overlaps; The other end is connected with flange, the external diameter of said flange interior outer diameter of steel pipes and outside between the outer diameter of steel pipes; The gap location of the overlap joint section of steel pipe and said outer steel pipe is inserted cement slurry in said, forms the expanding cement ring.
Preferably, the overlap joint section of interior steel pipe is twined a circle stirrup, can strengthen the intensity that steel pipe connects.
Preferably, the overlap joint section of interior steel pipe winding one circle stirrup is a spirality.
Advantage and the good effect that the utlity model has are: a kind of novel steel tube Placement of the utility model, and not high to construction environment and operator's technical requirements, be convenient to construction, and significantly reduce the installation time; Steel pipe uses flange to connect in it, and the steel pipe joint is coated with crust, makes to connect by the steel pipe beautiful shape smooth.

Embodiment
As shown in Figure 1; A kind of novel steel tube Placement of the utility model; Steel pipe 1 and outer steel pipe 2 in comprising, said interior steel pipe 1 has two, respectively with said outer steel pipe 2 deads in line; Steel pipe 1 one ends insert overlap joint in the said outer steel pipe 2 in said, and the overlap joint section 3 of interior steel pipe 1 is twined a circle spirality reinforcing bar; The other end is connected with flange 4, the external diameter value of said flange 4 interior steel pipe 1 external diameter and outside between steel pipe 2 external diameters; Steel pipe 1 is inserted cement slurry with the gap location of the overlap joint section 3 of said outer steel pipe 2 in said, forms the expanding cement ring.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
Claims (3)
