Abstract
The invention relates to an anchoring method for using a steel pipe to reinforce a compressed component. The method comprises the following steps of (1) leveling a ground surface; (2) anchoring an anchoring plate; (3) welding the anchoring plate and a steel pipe; (4) welding reinforcing ribs between the steel pipe and the reinforcing plate; and (5) casting a concrete protector. The method has the advantages that the application range is wide; the rigidity, the extensibility and the shear and vibration resistance functions of a reinforced column are favorably improved; the anchoring effect is good, the anchoring reliability is high, and the construction is convenient; the anchoring requirement is met, and meanwhile the engineering cost is reduced; and wide application prospect is realized.
Description
Technical field
The present invention relates to the civil construction project technical field, specifically a kind of anchoring process when adopting steel pipe to reinforce compressed member.
Background technology
Reinforced concrete structure is the topmost form of structure of China, and existing a large amount of existing structures need to carry out reinforcement and strengthening owing to the damage in the use procedure, disaster or use Functional change; In addition, along with encased structures and Appication, the research that this class formation is reinforced and use the attention that also is subject to gradually the researcher.In many reinforcement means, adopting steel pipe to reinforce compressed member is a kind of effective reinforcement means, not only can its bearing capacity and stiffness of Effective Raise, can also improve its anti-seismic performance.When using steel pipe to reinforce compressed member, effective anchoring on steel pipe and basis is to transmit the key that steel tube place shares load, also be that the performance steel pipe improves the necessary condition of its ductility to the effect of contraction that is reinforced compressed member, and help to improve antidetonation, shear behavior and the rigidity that is reinforced compressed member.
Summary of the invention
The purpose of this invention is to provide a kind of anchoring process when adopting steel pipe to reinforce compressed member, by welding, bolt and anchor plate steel pipe and basis be linked to be an integral body, realize steel pipe and basis effective anchoring so that the reinforcement effect of steel pipe be not fully exerted.
The anchoring process that the present invention is a kind of when adopting steel pipe to reinforce compressed member comprises the steps:
1, gets out anchoring at foundation ground and carry out levelling with bolt hole and to ground;
2, two semicircle annular anchor plates are anchored in ground to postwelding;
3, after steel pipe is reinforced compressed member, adopt weld seam to be connected anchor plate and steel pipe;
4, between steel pipe and anchor plate, weld stiffening rib;
5, concreting protective on the anchoring system that is formed by anchor plate, stiffening rib and bolt.
Described stiffening rib is steel plate or shaped steel.
The advantage of the anchoring process when the present invention adopts steel pipe to reinforce compressed member is:
1, the method applied range, the anchoring the during compressed members such as use steel pipe reinforced steel concrete, concrete filled steel tube and steel pipe is taken root and can be adopted the method;
When 2, adopting the method that steel pipe is carried out anchoring, the load effective communication that steel tube place can be shared arrives the basis, and helps to improve rigidity, ductility, shearing resistance and the antihunt action that is reinforced post.Not only anchoring effect is good for the method, anchorage reliability is high, and easy construction;
3, before using steel pipe reinforcing compressed member, just anchor plate is fixed on the ground, can when reinforcing, play certain location and fixation to steel pipe;
4, the concrete protective body that waters after not only can further strengthen anchoring by the bonding between steel pipe and the concrete, can also play a very good protection to anchoring system;
5, can reduce project cost when satisfying the anchoring requirement, be with a wide range of applications.
Description of drawings
Fig. 1 is the anchoring system schematic diagram before building;
Fig. 2 is the anchoring system schematic diagram after building.
Wherein: 1-ground, 2-anchor plate, 3-bolt, 4-steel pipe, 5-fillet weld, 6-stiffening rib, 7-concrete protective body.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further specified: as shown in Figure 1 and Figure 2, a kind of anchoring process when adopting steel pipe to reinforce compressed member comprises the steps:
1, gets out anchoring at foundation ground and carry out levelling with bolt hole and to ground;
2, use bolt anchoring in ground to postwelding two semicircle annular anchor plates;
3, after steel pipe is reinforced compressed member, adopt fillet weld to be connected anchor plate and steel pipe;
4, between steel pipe and anchor plate, weld stiffening rib;
5, concreting protective on the anchoring system that is formed by anchor plate, stiffening rib and bolt.
Described stiffening rib is steel plate or shaped steel.
