Abstract
The utility model provides a novel concrete post structure comprising claw steel, a connecting member and concrete. After the concrete is hardened, the claw steel, the connecting member and the concrete generate a favorable bonding force to be reliably combined together, thereby ensuring that the claw steel, the connecting member and the adjacent concrete can be together deformed under the action of an external load. The claw steel is a steel-made entity and comprises a plurality of steel claws extending outside the connecting edges of the entity, and the collecting edges are the gathering positions of the plurality of steel claws. The connecting member comprises a steel tube and a reinforcing steel bar connecting member and fixes the relative position of the claw steel through connecting with the claw steel. The novel concrete post structure can strengthen the constraint force of steel materials on the concrete, enhance the capacity of limiting the expansion of tiny cracks of the concrete and improve the compressive ultimate strength of the concrete and the joint working efficiency of steel materials, thereby improving the load bearing capacity of a concrete structure.

Background technology
At present, reinforced concrete structure obtains general development in the builing industry of various countries, constitute reinforced concrete structure material---steel concrete is made up of reinforcing bar and two kinds of diverse materials of physical and mechanical property of concrete.Concrete anti-pressure ability is strong and resistance to tension is very weak, and the tension of steel and anti-pressure ability are all very strong.Concrete and these two kinds of materials of reinforcing bar co-operation that combines, make concrete mainly bear pressure, reinforcing bar mainly bears pulling force to satisfy the instructions for use of engineering structures.
By retrieval, with the immediate technology of the utility model be the steel concrete rod structure, be characterized in making the material of reinforcing bar and these two kinds of different in kinds of concrete to combine and co-operation effectively.Possesses a series of advantage: rationally utilize the performance of reinforcing bar and two kinds of materials of concrete, well durable and fire resistance, globality and normability etc. preferably.But also there are some shortcomings in the steel concrete rod structure:
A. dead load is bigger;
B. reinforcing bar to concrete restraint forces a little less than, the ability of restriction concrete microcrack expansion is relatively poor, concrete ultimate compressive strength is lower;
C. build and take a lot of work, comprise the making of reinforcing bar, in place and colligation etc.
The utility model content
The purpose of this utility model is to remedy above-mentioned the deficiencies in the prior art, and a kind of new concrete rod structure is provided.Concrete is subjected to than strong constraint, strengthens the ability of restriction concrete microcrack expansion, improve concrete ultimate compressive strength, reduce the member section of concrete structure, reduce dead load.
For achieving the above object, the utility model provides a kind of new concrete rod structure, comprise pawl steel, connector and concrete, after the hardening of concrete, produced good adhesion stress between pawl steel and connector and the concrete, it is combined reliably, guarantee that pawl steel and connector and adjacent concrete can be out of shape jointly under the effect of outer load.
Described pawl steel is a kind of steel entity, is made up of the overhanging some steel pawls in the limit that crosses of entity, and the described limit that crosses is the place that converges of some steel pawls.
Ordinary circumstance, pawl ladle are drawn together two limit steel pawls and a middle steel pawl, and wherein the angle between two limit steel pawls is 270 °, and the angle between middle steel pawl and the limit steel pawl is 30-60 °, and two limit steel pawls have same width and thickness; The width of middle steel pawl is not less than limit steel pawl, and its thickness is not more than limit steel pawl.
Described pawl steel, ordinary circumstance has four kinds of production methods: directly rolling; Utilize T steel to bend; Utilize angle steel and band steel weldering system; Utilize three band steel weldering systems.Preferred preceding two kinds of production methods.
Described pawl steel, its outward flange to the distance of concrete surface is that thickness of concrete cover is 0-50mm.
Described connector comprises connector of steel tube and rebar connector, by with fix pawl steel relative position being connected of each pawl steel, connected mode for the welding.
Described connector of steel tube, ordinary circumstance is used to connect the middle steel pawl of each pawl steel.
Described rebar connector, ordinary circumstance is used to connect the limit steel pawl of adjacent pawl steel.Can also adopt a reinforcing bar to replace some rebar connectors, be linked in sequence helix shape along adjacent pawl steel.Its thickness of concrete cover is 15-40mm.
The utility model can strengthen steel to concrete restraint forces, strengthens the ability of restriction concrete microcrack expansion, improves concrete ultimate compressive strength, improves the co-operation efficient of steel, thereby improves the supporting capacity of concrete column structure.
Preferably, the utility model is that example is further described with the square sectional.
A. to form the cross section by concrete be foursquare solid column to a new concrete rod structure.
B. described a kind of concrete structure is provided with four pawl steel in concrete, the pawl steel lays respectively at four bights in cross section, the orientation column angle, limit that crosses of pawl steel, and two limit steel pawls are parallel to the horizontal edge and the longitudinal edge of square sectional respectively, and middle steel pawl overlaps with diagonal.The thickness of concrete cover of pawl steel is 0-50mm.
C. described a kind of new concrete rod structure is provided with connector, comprises connector of steel tube and rebar connector, by with fix pawl steel relative position being connected of each pawl steel, connected mode for the welding.Rebar connector is along mast axis direction pitch arrangement as required.
D. described connector of steel tube is used for connecting the middle steel pawl of whole pawl steel.
E. described rebar connector is used for connecting the limit steel pawl of adjacent pawl steel.Can also adopt a reinforcing bar to replace some rebar connectors, be linked in sequence helix shape along adjacent pawl steel.Its thickness of concrete cover is 15-40mm.
The utility model compared with prior art, the good effect of its advantage and generation is embodied in:
1, because the unique shape that has of pawl steel, its horizontal distortion is subjected to the direct restriction of connector of steel tube again, so compare with plain bars, the restriction ability of surrounding concrete is increased greatly.
2, because concrete along with on every side the constraint enhancing, the ability of restriction concrete microcrack expansion can be strengthened, concrete ultimate compressive strength also increases thereupon simultaneously, the supporting capacity of concrete column structure is improved, so the cross section of concrete component can reduce, help reducing dead load, generally can save concrete 20-40%.
3, because the pawl steel is arranged on the bight of structural section as main steel, the every pawl steel capital can effectively participate in resisting the moment of flexure effect of horizontal stroke, vertical both direction, the cooperative efficient of steel can be higher, so help reducing steel using amount, can save steel 5-20%.
