Background technology
When traditional newly-increased floor is with original beam consolidation process, the combination problem of new-old concrete can be all encountered.It is new and old mixed
The combination for coagulating soil, mainly by snap-in force, bond and frictional force.Wherein mechanical snap power is maximum, account for about the half of binding force with
On；Bond is mainly generated by the gelling property of cement；Frictional force is related with the stress of component, when bearing pulling force, no
Frictional force can be generated.Due to improper measures, attention is inadequate, performs a task perfunctorily, and secured strict purpose is often not achieved in junction,
There is crack, leakage, intensity deficiency and other issues.
Utility model content
The utility model is insufficient in order to solve the problems, such as newly-increased intensity between floor and original beam column, provides a kind of intensity more
Good connection structure.
The utility model provides base case：Newly-increased floor and original beam connection structure, including newly-increased floor with it is original
Beam；Newly-increased floor includes concrete layer and extends transversely through and be fixed on the floor bar in concrete layer, and original beam offers building
Plate reinforced hole, floor bar are inserted into floor bar hole, are filled with structure glue between floor bar and floor bar hole, original beam with
The contact surface of newly-increased floor is painted with interfacial agents；It is additionally provided with shear reinforcement in newly-increased floor, shear reinforcement is shorter than floor bar, former
There is beam to offer shear reinforcement hole, shear reinforcement is inserted into shear reinforcement hole and is filled with structure glue.
The concrete layer of newly-increased floor makes newly-increased floor itself have stronger globality and structural strength with floor bar.
Floor bar is fixed with floor bar hole, increases the bonding strength of the two horizontal direction by structure glue, by the knot of floor bar
Structure carrys out the shearing force of load vertical direction.Brushing interfacial agents reduce the gap of the two junction.Shear reinforcement, shear reinforcement are set
The structural stress of newly-increased floor is not needed to undertake, one end of which is fixed in concrete layer, the other end is implanted by structure glue
In shear reinforcement hole, major function is to assist the newly-increased shearing force between floor and original beam of floor bar load.
Compared with prior art, it is the advantages of this programme：According to the connection structure between newly-increased floor and original beam by
The larger feature of vertical shearing power is provided with shear reinforcement, and shear reinforcement is not necessarily to such as what kind of length of floor bar, therefore saves
Cost, while effectively enhancing the shear resistance of newly-increased floor and original beam junction.
Scheme two：Outer wall for the preferred of basic scheme, the shear reinforcement is equipped with thread segment.Advantageous effect：Thread segment
Shear reinforcement is more effectively fixed in shear reinforcement hole by the friction coefficient that can effectively increase shear reinforcement.
Scheme three：Further include shearing resistance angle steel for the preferred of scheme two, the shearing resistance angle steel be equipped with integrally formed left plate with
Right panel, the left plate are posted and fixed in the lower face of newly-increased floor, and the right panel is posted and fixed in the side of original beam.Have
Beneficial effect：Left plate withstands newly-increased floor, and right panel is fixed on original beam, is increased by right panel and the vertical load force of left plate new
Increase the shear resistance of floor and original beam junction.
Scheme four：For the preferred of scheme three, anchor bolt is all made of between the left plate and newly-increased floor and right panel and original beam
It is fixed.Advantageous effect：Anchor bolt can increase the bonding strength between shearing resistance angle steel and newly-increased floor and original beam, avoid increasing newly
Floor stress is detached from.
Scheme five：For the preferred of scheme four, the right panel is located under newly-increased floor.Advantageous effect：Right panel stretches into newly-increased
The area that the leakage of shearing resistance angle steel can be reduced between floor and original beam improves beauty, but enhances difficulty of construction, while may apply
Increase the destruction to original beam during work.
