Abstract

The utility model discloses a kind of bending resistance hollow steel tube concrete supports, including oval inner tube, circular outer pipe and inner support, oval inner tube concentric is placed in circular outer pipe, the outer wall of the long axis direction of oval inner tube is connect by round reinforcing bar with circular outer pipe respectively, cavity between oval inner tube and circular outer pipe is filled with concrete, inner support is placed in oval inner tube, and is abutted with the inner wall of oval inner tube.The utility model enhances the internal intensity of component by round reinforcing bar, oval internal tube replaces casting concrete by inner support, round reinforcing bar is cooperated to improve the whole bending resistance of building jointly, and member dead weight is greatly lowered, and has saved a large amount of concrete material.

Description

A kind of bending resistance hollow steel tube concrete support
Technical field
The utility model belongs to steel pipe processing technique field, in particular to a kind of bending resistance hollow steel tube concrete support.
Background technique
In concrete filled steel tube, steel pipe can make concrete be in three dimension stress state, and steel pipe can be improved in concrete Rigidity, the two play a role jointly, so that bearing capacity substantially enhances.It is safe and reliable etc. excellent since with intensity height, stability is good Point, in recent years, steel pipe concrete bracket are widely used in soft rock roadway support, and achieve preferable supporting effect.
Currently used for the CFSTsupport member of roadway support, first Prefabricated concrete-filled steel tube bracket is (in pipe before constructing First not casting concrete), it transports to tunnel, component is installed on by the tunnel to supporting by casing, is then poured to component inside Build customary commercial concrete.These components alleviate the awkward situation that soft-rock tunnel is difficult to supporting to a certain extent, but scene is propped up In shield, often there is bending failure in component, and component bending resistance is insufficient, and member dead weight is excessive, is unfavorable for itself stress.
Utility model content
For the technical problems in the prior art, the utility model provides a kind of bending resistance hollow steel tube concrete branch Frame.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of bending resistance hollow steel tube concrete support, including oval inner tube, circular outer pipe and inner support, the ellipse Inner tube concentric is placed in circular outer pipe, and the outer wall of the long axis direction of the ellipse inner tube passes through round reinforcing bar and circle respectively Outer tube connection, the cavity between the ellipse inner tube and circular outer pipe are filled with concrete, and the inner support is placed in ellipse In inner tube, and abutted with the inner wall of oval inner tube.
Preferably, the inner support includes central siphon, supporting plate and supporting plate, the outer wall of the central siphon is uniformly distributed to be set there are four axial The supporting plate set, the supporting plate are connected with supporting plate far from one end of central siphon, and the supporting plate has to be cooperated with the inner wall of oval inner tube The outer surface of fitting, the central siphon and circular outer pipe concentric are arranged.
Preferably, the supporting plate and shaft pipe welding, the supporting plate and supporting plate weld.
A kind of this practical new novel bending resistance hollow steel tube concrete support, has the advantages that the utility model The internal intensity of component is enhanced by round reinforcing bar, oval internal tube replaces casting concrete, cooperation by inner support Round reinforcing bar improves the whole bending resistance of building jointly, and member dead weight is greatly lowered, and has saved a large amount of concrete Material.
Detailed description of the invention
Fig. 1 is a kind of bending resistance hollow steel tube concrete support schematic cross-sectional view in the utility model.
Specific embodiment
It is with reference to the accompanying drawing and specific real to make those skilled in the art better understand the technical solution of the utility model Example is applied to elaborate to the utility model.
As shown in Figure 1, a kind of bending resistance hollow steel tube concrete support, including oval inner tube 1, circular outer pipe 2 and Nei Zhi Frame, oval 1 concentric of inner tube are placed in circular outer pipe 2, and the outer wall of the long axis direction of oval inner tube 1 passes through circular steel respectively Muscle 3 is connect with circular outer pipe 2, and the cavity between oval inner tube 1 and circular outer pipe 2 is filled with concrete 4, and inner support is placed in ellipse In circular inner pipe 1, and abutted with the inner wall of oval inner tube 1.
In the present embodiment, inner support includes central siphon 5, supporting plate 6 and supporting plate 7, and the outer wall of central siphon 5 is uniformly distributed, and there are four axial settings Supporting plate 6, supporting plate 6 is connected with supporting plate 7 far from one end of central siphon 5, and supporting plate 7 has to be bonded with the cooperation of the inner wall of oval inner tube 1 Outer surface, central siphon 5 and 2 concentric of circular outer pipe are arranged.
In the present embodiment, supporting plate 6 and central siphon 5 are welded, and supporting plate 7 and supporting plate 6 weld, the inner wall of supporting plate 7 and oval inner tube 1 It abuts, the form connected using this on-fixed, increases the toughness and elasticity between supporting plate 7 and oval inner tube 1, enhance The anti-bending strength of component entirety.
One of the utility model bending resistance hollow steel tube concrete support when in use, enhances structure by round reinforcing bar The internal intensity of part, oval internal tube replace casting concrete by inner support, and round reinforcing bar is cooperated to improve structure jointly Whole bending resistance is built, and member dead weight is greatly lowered, and has saved a large amount of concrete material.
Above embodiments are only the exemplary embodiment of the utility model, are not used in limitation the utility model, this is practical new The protection scope of type is defined by the claims.Those skilled in the art can be in the essence and protection scope of the utility model It is interior, various modifications or equivalent replacements are made to the utility model, this modification or equivalent replacement also should be regarded as falling in originally practical new In the protection scope of type.
