Abstract

The invention discloses a high-strength bolt shear key structure and a constructing method of the high-strength bolt shear key structure. The high-strength bolt shear key structure comprises a steel beam composed of steel beam web plates and steel beam flange plates, a precast concrete plate, high-strength bolts and a connecting part formed by an upper cushion plate, a lower cushion plate and a supporting steel pipe, wherein the upper end and the lower end of the supporting steel pipe abut against and are fixed to the upper cushion plate and the lower cushion plate respectively, and the connecting part is cast in the precast concrete plate. The method includes the steps that the steel beam web plates and the steel beam flange plates are manufactured into the I-beam-type steel beam, meanwhile, the precast concrete plate is manufactured, the connecting part formed by the upper cushion plate, the lower cushion plate and the supporting steel pipe are cast in the designed position of the precast concrete plate, and the supporting steel pipe is clamped between the upper cushion plate and the lower cushion plate; the steel beam is paved with the precast concrete plate, and the supporting steel pipe of the connecting part serves as a formwork for hole drilling; the precast concrete plate and the steel beam flange plates are connected through bolts to be in an attached state, and the precast concrete plate and the flange plates can be connected through clamping force of the high-strength bolts.

Description

A kind of high-strength bolt shear key structure and construction construction method thereof
Technical field
The present invention relates to a kind of being used for and connect the high-strength bolt shear key structure of girder steel and precast concrete plank and build construction method, belong to civil works building technology field.
Background technology
Prefabricated assembled steel-concrete combined structure is combined into whole co-operation by shear connector by girder steel and precast concrete plank, can give full play to the advantage separately of Steel concrete bi-material, there is the advantages such as environmental friendliness, easy construction, good economy performance, apply increasingly extensive.
Shear connector is the critical component in steel-concrete combined structure, and form has a variety of.High-strength bolt shear key is formed the frange plate of precast concrete plank and girder steel to be connected by the chucking power of high-strength bolt, has the advantages such as quality of connection is easy to guarantee, quick construction is convenient, concrete slab replacing is easy, has broad application prospects.In at present common high-strength bolt shear key, concrete directly bears the pre-applied force of high-strength bolt, and in part, heavily stressed lower concrete creeping causes that the problem that high-strength bolt pretension is lax is more outstanding, causes the reduction of combining structure switching performance.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, easy construction, can effectively reduce the high-strength bolt shear key structure that pretension is lax and build construction method.
Technical scheme of the present invention is:
A high-strength bolt shear key structure, comprises the connector that girder steel, precast concrete plank, high-strength bolt and upper padding plate, lower bolster and supporting steel pipe that steel beam web plate and girder steel frange plate form form; The two ends up and down of described supporting steel pipe offset with upper padding plate and lower bolster respectively and are fixing, described girder steel frange plate, upper padding plate and lower bolster are equipped with the circular hole with high-strength bolt adaptation on the axis of supporting steel pipe, the internal diameter of described supporting steel pipe is not less than the diameter of above-mentioned circular hole, and described connector is built in precast concrete plank.
A kind of construction construction method of high-strength bolt shear key structure, first steel beam web plate and girder steel frange plate are manufactured to the girder steel of I-beam type, carry out the making of precast concrete plank simultaneously, and the connector being comprised of upper padding plate, lower bolster and supporting steel pipe is cast on the design attitude of precast concrete plank, and described supporting steel pipe is clipped in therebetween by upper padding plate and lower bolster; Then complete the field erection of girder steel, then on girder steel, carry out the laying of precast concrete plank, and utilize the supporting steel pipe of connector to hole as template; Finally that the frange plate bolt of precast concrete plank and girder steel is in place to fit-state, the chucking power by high-strength bolt makes both form connection.
The invention has the beneficial effects as follows: the present invention is simple in structure, easy construction, supporting steel pipe is not only the duct of high-strength bolt in precast concrete plank, and be the support frame of high-strength bolt, bear the most pre-applied force of high-strength bolt, thereby greatly reduce the pressure that concrete bears, concrete creeping significantly reduced, can effectively reduce the lax of high-strength bolt pretension, strengthen shearing concatenation ability and the intensity of combining structure.
