Description
Technical field
The present invention relates to girders to widen area through bolt of long stem connection in secondary beam, and in particular to the girder of being dismounted for multiple times is secondary
Beam widens area and runs through bolt of long stem connecting node and connection method.
Background technology
Currently, for prefabricated assembled primary and secondary beam nodes in building structure connection generally there are three types of form：1 precast main beam
Upper cast-in-place concrete secondary beam, this node are slow due to needing supporting module, speed of application；2 prefabricated secondary beams are shelved on precast main beam side
Edge realizes the connection of primary-secondary beam by cast-in-place node area concrete, and the speed of application of this node is fast, but globality is poor；3 is pre-
Secondary beam processed is shelved on precast main beam edge, and integrated connection, construction are realized by the cast-in-place concrete for building secondary beam and node area in part
Speed, therefore the application in Practical Project is wider.But it can cause to be easy to happen cracking phenomena at node, construction quality is not
Easily ensure, position of joints easily becomes weak link.
Invention content
The present invention is to be easy at the node for solving to use caused by the connection method of existing prefabricated assembled primary and secondary beam nodes
Cracking phenomena occurs, construction quality is not easy to ensure, position of joints easily becomes weak link, the company of prefabricated assembled primary and secondary beam nodes
Connecing the node point connection caused by method is inconvenient to dismantle, the problem of cannot carrying out being dismounted for multiple times, and then provides being dismounted for multiple times
Girder widens area in secondary beam and runs through bolt of long stem connecting node and connection method.
The present invention adopts the technical scheme that in order to solve the above problem：It includes girder, secondary beam end local widening area, more
A anchor slab, multiple prestressing force bolt of long stem and multiple high-strength nuts, the upper surface in secondary beam end local widening area are machined with multiple
The stirrup widened is machined with multiple through-holes on anchor slab, and multiple prestressing force bolt of long stem levels are inserted on girder, secondary beam end office
The both sides that area and secondary beam junction end are widened by portion are set vertically respectively there are two anchor slab, on girder with time beam end part is installed
Widen on the opposite girder side in area and set there are two anchor slab, one end of each prestressing force bolt of long stem passes through time beam end locally to add
Wide area is simultaneously arranged on anchor slab, and the other end of each prestressing force bolt of long stem is arranged on the anchor slab of girder, and each prestressing force is long
The often end of bar bolt is anchored at by high-strength nut on anchor slab respectively.
The method is realized according to the following steps：
Step 1：Make girder and secondary beam：It pours girder and secondary beam, and carries out local widening in one end of secondary beam and formed time
Beam end local widening area reserves the duct of stress bolt of long stem insertion in widening on section for girder and secondary beam, is pouring
Multiple stirrups widened are uniformly arranged when secondary beam end local widening area above secondary beam end local widening area；
Step 2：Connection：Multiple stress bolt of long stem are inserted into respectively on girder and time beam end local widening area, and secondary
The both sides of beam end local widening area and secondary beam junction end are set vertically respectively there are two anchor slab, on girder with secondary beam is installed
Anchor slab there are two being set on the opposite face in end local widening area, one end of each stress bolt of long stem passes through high-strength nut and secondary beam
The other end of the anchor slab anchoring being arranged in the local widening area of end, each stress bolt of long stem passes through high-strength nut and close girder
On anchor slab anchoring, and then complete assembled girder secondary beam widen area run through bolt of long stem connecting node connection.
The beneficial effects of the invention are as follows：
The connection of the present invention prefabricated assembled primary and secondary beam nodes suitable for building structure.The present invention is compared with prior art
It has the advantages that：1. the construction of the present invention is convenient, speed of application is fast, construction quality is easily guaranteed that；2. the side of the present invention
Method makes the firm and reliable connection of primary-secondary beam, can reach and connect identical even higher bearing capacity and reliability with cast-in-place primary-secondary beam
Purpose；3. the present invention keeps the rigidity at node big, deformation is small, it is not easy to it is existing that cracking occur due to applying prestressing force to node
As.
