Abstract
The utility model discloses a kind of hollow steel pipe concrete column for slope of highway supporting, it includes outer steel pipe and interior steel pipe, outer steel pipe is arranged concentrically with interior steel pipe, the more horizontal stiffeners for extending radially through interior steel pipe along interior steel pipe are distributed with the circumference of interior steel pipe, composite steel rib ring is provided between outer steel pipe and interior steel pipe, horizontal stiffener welds with steel ring, the equally distributed longitudinally reinforced reinforcing bar of the more circumferences along steel ring is welded with the outside of steel ring, the inwall of outer steel pipe has been distributed uniformly and circumferentially polylith and has strengthened steel plate, strengthen both ends and welding that steel plate seals in longitudinally reinforced reinforcing bar, concrete solid is perfused with the space that outer steel pipe and interior steel pipe enclose.The utility model can take into account bearing capacity, shock resistance and cooperative bearing performance.
Description
Technical field
Technical field of civil engineering is the utility model is related to, more particularly to a kind of hollow steel for slope of highway supporting
Pipe concrete column.
Background technology
Concrete filled steel tube is to insert a kind of new composite structure formed in steel pipe by concrete.Because steel pipe mixes
The advantages of Xtah Crude Clay structure can more effectively play two kinds of materials of steel and concrete each, can be such that concrete is in the structure
Three dimension stress state, its compression strength can significantly improve, while overcome the shortcomings that local buckling easily occurs for steel-tube construction.
In recent years, it has been widely used in supporting field.
The hollow steel pipe concrete column that currently there are, led in addition to concrete without other attachment structures between two steel pipes
The cooperative bearing poor-performing of steel pipe and concrete is caused, both can not effectively interact in enclosed space, plus steel pipe
The cast of inner concrete belongs to concealed work, and the pouring quality of concrete is difficult to ensure, so as to greatly reduce concrete filled steel tube
The original bearing capacity of post and shock resistance.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of hollow steel pipe coagulation for slope of highway supporting
Earth pillar, bearing capacity, shock resistance and cooperative bearing performance can be taken into account.
In order to solve the above technical problems, the technical scheme that the utility model uses is:One kind is provided and is used for highway side
The hollow steel pipe concrete column of slope supporting, including outer steel pipe and interior steel pipe, the outer steel pipe are arranged concentrically with interior steel pipe, described interior
The more horizontal stiffeners for extending radially through interior steel pipe along interior steel pipe, the outer steel pipe and interior steel are distributed with the circumference of steel pipe
Composite steel rib ring is provided between pipe, the horizontal stiffener welds with the steel ring, is welded with the outside of the steel ring
The equally distributed longitudinally reinforced reinforcing bar of the more circumferences along steel ring, the inwall of the outer steel pipe have been distributed uniformly and circumferentially
Polylith strengthens steel plate, both ends and the welding strengthened steel plate and seal in longitudinally reinforced reinforcing bar, is enclosed in the outer steel pipe and interior steel pipe
Close in the space formed and be perfused with concrete solid.
The beneficial effects of the utility model are:It is different from the situation of prior art, the week of the present utility model in interior steel pipe
The horizontal stiffener through interior steel pipe is set up, steel ring and longitudinally reinforced reinforcing bar are set between interior steel pipe and outer steel pipe,
Horizontal stiffener and longitudinally reinforced reinforcing bar weld with steel ring, and the reinforcement steel plate on outer steel pipe inwall seals in longitudinally reinforced again
Reinforcing bar both ends are simultaneously welded, and inside, concrete perfusion entity between outer steel pipe, so as to take into account bearing capacity, shock resistance
With cooperative bearing performance.
Brief description of the drawings
Fig. 1 is the structural representation for the hollow steel pipe concrete column that the utility model embodiment is used for slope of highway supporting.
Fig. 2 is the plan structure signal for the hollow steel pipe concrete column that the utility model embodiment is used for slope of highway supporting
Figure.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only part of the embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refering to Fig. 1 and Fig. 2, the hollow steel pipe concrete column for slope of highway supporting of the utility model embodiment includes
Outer steel pipe 1 and interior steel pipe 2, outer steel pipe 1 are arranged concentrically with interior steel pipe 2, and more are distributed with the circumference of interior steel pipe 2 along interior steel pipe 2
The horizontal stiffener 3 for extending radially through interior steel pipe 2, be provided with composite steel rib ring 4 between outer steel pipe 1 and interior steel pipe 2, laterally strengthen
Reinforcing bar 3 welds with steel ring 4, and the outside of steel ring 4 is welded with the equally distributed longitudinally reinforced steel of the more circumferences along steel ring 4
Muscle 5, the inwall of outer steel pipe 1 have been distributed uniformly and circumferentially polylith and have strengthened steel plate 6, strengthened steel plate 6 and seal in longitudinally reinforced reinforcing bar 5
Both ends and welding, be perfused with concrete solid 7 in the space that outer steel pipe 1 and interior steel pipe 2 enclose.
Due between outer steel pipe 1 and interior steel pipe 2 in addition to having concrete solid 7, also horizontal stiffener 3, steel ring
4th, the reinforcing bar reinforcement structure that waling 5 and reinforcement steel plate 6 are formed, therefore bearing capacity, shock resistance and association can be taken into account
Same stress performance.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
