Description
Technical field
The invention belongs to Structural Engineering and technical field of bridge engineering, be specifically related to a kind of shear stiffness controllable section steel and concrete combined connection component and using method thereof.
Background technology
The mechanical property of steel and concrete combined structure not only is subjected to the influence of self material property, and with the shearing resistance effect of bonding surface connector much relations is arranged.The main at present connector that uses all has a common characteristic, and promptly connector has very big shear stiffness from the beginning, can't consider the requirement of work progress and material property.Particularly combining structure bridge concrete is applied the prestressed construction stage,, make and steel and concrete acting in conjunction cause loss of prestress and concrete to damage because the shear stiffness of connector is very big; Another kind of rough sledding is that steel work has limited concrete shrinkage strain, causes producing time internal force in the concrete, shrinks the crack easily.
Summary of the invention
The object of the present invention is to provide a kind of rigidity-controllable section steel and concrete combined connection component and using method thereof.
Rigidity-controllable section steel and concrete combined connection component that the present invention proposes are made up of pipe 1 and filling member 2, and pipe 1 is the hollow structure in middle part, and filling member 2 is positioned at this hollow part, and described filling member 2 is the mixture of high hardness resin and silica sand.
Among the present invention, described pipe 1 outer wall is smooth, also can be threaded 11 or the end have nut 12.
One of the rigidity-controllable section steel that the present invention proposes and using method of concrete combined connection component, this combined connection component directly is arranged between steel plate 3 and the concrete 5, concrete grammar is: pipe 1 one ends are welded on the steel plate 3, and filling filling member 2, be furnished with in length and breadth to reinforcing bar 4 around the pipe 1, concreting 5 again, and pipe 1, filling member 2, reinforcing bar 4 all are positioned at concrete 5.
The rigidity-controllable section steel that the present invention proposes and the another kind of using method of concrete combined connection component, this combined connection component is used between perforate steel plate 6 and the concrete 5, concrete grammar is: perforate steel plate 6 is welded on the steel plate 3, the pipe 1 that is filled with filling member 2 is penetrated the through hole of perforate steel plate 6, arrange in length and breadth to reinforcing bar 4, concreting 5 again, and pipe 1, reinforcing bar 4 and perforate steel plate 6 all are positioned at concrete 5.
The using method of rigidity-controllable section steel of the present invention and concrete combined connection component, specific practice is that pipe is welded on the steel plate, perhaps pipe is penetrated in the perforate steel plate, and in pipe, fill the mixture of high hardness resin and silica sand, concreting connects steel and concrete requirement to reach.High hardness resin is a colloid, will harden after placing certain hour, and the time that reaches sclerosis can be regulated by the addition of adjusting hardener.In resin, cooperate a certain proportion of silica sand, can improve modulus of elasticity and viscosity.That is to say that this high hardness resin mortar is a kind of material of rigidity retarded type, and can adjust lag time that the pipe of filling with it uses as combined connection component, it just has ageing on intensity and rigidity.In addition, can on pipe, engrave screw thread, also can nut be installed in the pipe end, with the pulling capacity between opposing steel and the concrete.
Because the shear stiffness of combined connection component belongs to controllable type, the present invention has following characteristics:
(1) according to the different needs of structure stress, select the form of controllable stiffness type combined connection component, round steel pipe can be welded on the steel plate, and fill the high hardness resin mortar and use, also the pipe of filling the high hardness resin mortar can be applied in the perforate steel plate and use;
(2) can reduce combining structure prestressing force and apply the adverse effect of stage structure stress;
(3) can reduce the influence of concrete shrinkage deformation in the combining structure, prevent the generation of concrete shrinkage crack;
(4) making of controllable stiffness type combined connection component is simple, can improve the adverse effect to the combining structure stress performance such as work progress, concrete shrinkage deformation.
Rigidity-controllable section steel and concrete combined connection component that the present invention proposes have the advantages that shear stiffness can be regulated: the construction stage shear stiffness when promptly allowing relative slippage between steel and concrete is less, but can guarantee not break away from; Shear stiffness operation stage when needing to combine fully between steel and concrete can reach very big again, and is basic identical with common connector performance, can satisfy the requirement of material property and work progress better.
