The invention discloses a kind of polygon steel pipe concrete column, including inside for the polygonal steel pipe of concrete perfusion, the inner wall surface of the polygonal steel pipe is equipped with to the reinforcement rib structure protruded inside pipe and then applies to the concrete and hold restraining force tightly.The outer wall of the polygonal steel pipe is equipped with dent, and the back side of the dent protrudes from the inside of the polygonal steel pipe, and a plurality of dent forms the reinforcement rib structure.The a plurality of dent positioned at the same polygon steel pipe outer wall is two-by-two with respect to the groove structure or notch configuration for combining setting and then formation round shape.The anchor ear effect that the present invention is formed due to set ribs, not only increases the cement bearing capacity of rectangular conduit, and but also the bond strength between steel pipe walls and cement increases, so as to improve the synthesis stress problem of steel core concrete column.
Description
Technical field
The present invention relates to a kind of polygon steel pipe concrete columns.
Background technique
Concrete filled steel tube is a kind of novel building system, it is to be formed using the internal cement of outer steel pipe in pressure-bearing
Restraining force, to increase the technique of the bearing capacity of column, about twice is can be improved in the more general cylinder of bearing capacity.
However, applied steel pipe shape, square tube or rectangular tube have very big shortcoming, that is, round tube is to pipe compared with round tube
Interior cement has the effect of anchor ear power (or restraining force) very and square tube or rectangular tube are difficult to reach round tube.
Wherein reason is mainly that square tube or rectangular tube only have each corner to have preferable restraining force to cement in pipe,
And the plane tube wall of surrounding, to cement restraining force very little, this just causes, and square tube or rectangular tube are compared compared with round tube, possessed carrying
Power about loses 30 percent.
Summary of the invention
Purpose of the invention is to overcome the shortcomings in the prior art, provides a kind of polygon steel pipe concrete column.
In order to achieve the above object, being achieved through the following technical solutions:
A kind of polygon steel pipe concrete column, including inside for the polygonal steel pipe of concrete perfusion, the polygon steel
The tube wall surface of pipe is equipped with to the reinforcement rib structure protruded inside pipe and then applies to the concrete and hold restraining force tightly.
Preferably, the outer wall of the polygonal steel pipe is equipped with dent, and the back side of the dent protrudes from the polygon steel
The inside of pipe, a plurality of dent are staggered or uniformly distributed and form the reinforcement rib structure.
The a plurality of dent for being preferably located at the same polygon steel pipe outer wall combines setting in turn relatively two-by-two
Form the groove structure or notch configuration of round shape.
Preferably, every arc-shaped strip of dent, the groove structure or the notch configuration are in long oblate or circle
Shape or class rectangle shape.
Preferably, the inner wall of the polygonal steel pipe is equipped with a plurality of reinforcement rib of self-deformation, every ribs
The both ends of muscle are fixed in the inner wall of the polygonal steel pipe, and the deformation section for reinforcing rib is to the inside of the polygonal steel pipe
Protrusion.
Preferably, the reinforcement rib is arc-shaped or waveform is bent.
Preferably, the reinforcement rib is triangular in shape or rectangular bent.
The beneficial effect of polygon steel pipe concrete column of the present invention includes:
By plane tube wall surface of the special processing technology to rectangular tube, ribs (or in tendon shape or plate) is set, with
Reinforce plane tube wall to the restraining force (improving 10%-20%) of cement, to increase column bearing capacity (improving 5%), enhancing is put down
Anchor ear power (increase 10%-20%) of the facial canal wall to cement in cylinder.

Specific embodiment
The present invention is described in detail with reference to the accompanying drawing:
A kind of polygon steel pipe concrete column, including inside for the polygonal steel pipe 1 of concrete perfusion, the polygon steel
(surface including inner wall or outer wall) is equipped with to the reinforcement rib structure protruded inside pipe and then to the concrete on the tube wall of pipe 1
Apply and holds restraining force tightly.
More preferably, the polygonal steel pipe 1 can be rectangular steel pipe, rectangular steel tube, diamond shape steel pipe, parallelogram
In the existing constructions such as steel pipe, hexagon steel pipe, octagon steel pipe it is conventional it is thinkable can similar substitution polygonal steel pipe.
Enumerate the example of two different structure forms respectively below for ribs:
Embodiment one:
As depicted in figs. 1 and 2, the outer wall surface of above-mentioned polygonal steel pipe 1 is set by way of punching press or laser-induced thermal etching
Dent 2 is set, the back side of the dent 2 protrudes from the inside of the polygonal steel pipe 1, and a plurality of dent 2 is with having high and low fall
Be staggered laying or the uniformly distributed formation reinforcement rib structure.
As shown in figure 1, positioned at a plurality of dent 2 of same 1 outer wall of polygonal steel pipe, opposite combine is arranged two-by-two
And then form the groove structure or notch configuration 3 of round shape.More preferably, be formed by different tube wall surfaces groove structure or
Notch configuration 3 there are high and low fall is arranged in a staggered manner.
Further, in conjunction with shown in Fig. 3 and Fig. 4, half extended to tube wall center is also can be set in the tube wall edge of steel pipe 1
Dent 2 is cut, the dent 2 on different tube wall edges is also possible to there are high and low fall be arranged in a staggered manner.
More preferably, there can be interval between two adjacent dents 2 or not be spaced, every dent 2 is in arc
Shape strip, the groove structure or the notch configuration 3 are in long oblate or round or class rectangle shape.
Embodiment two:
As shown in Figures 5 to 9, the inner wall surface of the polygonal steel pipe 1 is equipped with self-deformation and uniformly distributed a plurality of
Reinforce rib 4 (reinforcing bar), every both ends for reinforcing rib 4 are fixed in the inner wall of the polygonal steel pipe 1, the ribs
The deformation section of muscle 4 is protruded to the inside of the polygonal steel pipe 1.
As shown in Figure 6 and Figure 7, more preferably, the reinforcement rib 4 is arc-shaped or waveform is bent.Such as Fig. 8 and Fig. 9
It is shown, or, the reinforcement rib 4 is triangular in shape or rectangular bent.
Polygon steel pipe concrete column provided by the present invention, due to the anchor ear effect that set ribs is formed, not only
Improve the cement bearing capacity of rectangular conduit, and but also the bond strength between steel pipe walls and cement increases, thus
Improve the synthesis stress problem of steel core concrete column.
