Abstract
The utility model relates to a steel pipe sleeve connector which comprises a steel sleeve used for butting a first steel pipe and a second steel pipe, wherein the steel sleeve is tightly sleeved outside the first steel pipe and the second steel pipe which have the same outer diameter and fixed with the steel pipes through two groups of self-tapping screws, wherein one group of the self-tapping screws vertically penetrates the sleeve wall of the steel sleeve and the pipe wall of the first steel pipe from outside to inside, and the other group of the self-tapping screws vertically penetrates the sleeve wall of the steel sleeve and the pipe wall of the second steel pipe from outside to inside. The steel pipe sleeve connector has the advantages of no damage to the strength of the butted steel pipes, saved material, low integrated cost and convenient and rapid construction, is suitable for connection for all steel pipes, and is particularly suitable for connection among the rectangular, square and circular thin-wall steel pipes.
Description
Technical field
The utility model relates to a kind of steel pipe connector, particularly a kind of connector that connects thin-wall steel tube.
Background technique
Traditional docking mode of steel pipe generally has welding, bolt connection, crab-bolt to connect and be connected with compression sleeve.Its deficiency is that tradition connects complex process, and cost is higher, and construction is inconvenient, is unsuitable for the thin-wall steel tube butt joint.For thin-walled light steel tube material, because wall is thin, traditional Placement causes damage to material easily, influences structural safety.
The model utility content
In order to solve light thin wall steel pipe interconnection technique problem, overcome the deficiency of traditional welding, bolt and crab-bolt Placement, the utility model proposes a kind of steel pipe socket coupling sleeve.Not only have effect safe and reliable, with low cost, also have installation rate fast, be convenient to advantages such as operation.
The scheme that the utility model is dealt with problems is:
A kind of steel pipe socket coupling sleeve, comprise the steel bushing that is used to dock first steel pipe and second steel pipe, described steel bushing tightly is enclosed within outside first steel pipe and second steel pipe with same outer diameter as, fix by two groups of self tapping screws between steel bushing and the steel pipe, wherein one group of self tapping screw is from vertically penetrating the steel bushing barrel and the first steel pipe tube wall outside to inside, and another group self tapping screw is from vertically penetrating the steel bushing barrel and the second steel pipe tube wall outside to inside.
The cross section of described first steel pipe, second steel pipe and Steel Sleeve can be rectangle or circle.
The pipe thickness of described first steel pipe and second steel pipe can be identical or inequality.
The external diameter of the external diameter of described first steel pipe, second steel pipe is identical with the internal diameter of steel bushing.
Described first steel pipe also holds out against in the steel bushing neutral position mutually with the termination of docking of second steel pipe.
Described self tapping screw can evenly be arranged at interval along the Steel Sleeve border.
The beneficial effects of the utility model are as follows: the utility model does not damage the intensity of steel pipe, saves material, and overall cost is cheap, and convenient and quick construction is applicable to the connection of all steel pipes, is particularly useful for the connection between thin-walled rectangle, the square and round steel pipe.
Description of drawings
Fig. 1 is the utility model steel pipe socket coupling sleeve structural representation.
Fig. 2 is the sectional drawing of the A-A section illustrated embodiment one square steel pipe sleeve coupler of Fig. 1.
Fig. 3 is the sectional drawing of the A-A section illustrated embodiment two round steel pipe sleeve couplers of Fig. 1.
Reference character: 1-steel bushing, 2-the first steel pipe, 3-the second steel pipe, 4-self tapping screw.
Embodiment
Below in conjunction with drawings and Examples model utility is described further:
This steel pipe socket coupling sleeve, as Fig. 1, Fig. 2, shown in Figure 3, between first steel pipe 2 and second steel pipe 3, connect by steel bushing 1, the interior sectional dimension of described steel bushing 1 is identical with the outer sectional dimension of first steel pipe 2 or second steel pipe 3, and first steel pipe 2 is identical with second steel pipe, 3 outer sectional dimensions, and the termination, joint of first steel pipe 2 and second steel pipe 3 is positioned at steel bushing 1 neutral position and holds out against mutually.Fixing between described connector steel bushing 1 and the steel pipe by self tapping screw 4, self tapping screw 4 is evenly arranged along the sleeve border, wherein one group of self tapping screw 4 is from vertically penetrating the barrel of steel bushing 1 and the tube wall of first steel pipe 2 outside to inside, another group self tapping screw 4 is from vertically penetrating the barrel of steel bushing 1 and the tube wall of second steel pipe 3 outside to inside, and self tapping screw 4 quantity are determined according to calculating.
Described Steel Sleeve connector, the cross section outside dimension of first steel pipe 2 and second steel pipe 3 is identical with the cross section inside dimension of steel bushing 1, guarantees that steel pipe is connected closely with Steel Sleeve.First steel pipe 2 is identical with the cross section outside dimension of second steel pipe 3, thickness of steel pipe can be identical also can be different.The wall thickness of described Steel Sleeve is not less than the higher value of first steel pipe 2 and second steel pipe, 3 wall thickness.
Fig. 2 is the schematic cross section of square steel pipe sleeve coupler, and Fig. 3 is the schematic cross section of round steel pipe sleeve coupler.The two difference is the sectional shape difference of steel pipe.The shape of sleeve pipe changes with the alteration of form of steel pipe.
