Description

Reinforcing device of assembled frame beam and assembled frame beam comprising same

Technical Field

The utility model belongs to the technical field of the building and specifically relates to a reinforcing apparatus of assembled frame roof beam and contain device's assembled frame roof beam is related to.

Background

Generally, when the reinforcement at the top of the beam end in the fabricated frame structure is insufficient, a steel plate or carbon cloth needs to be adhered to the corresponding portion for performing an equivalent reinforcing treatment. Because this part is located near the node and often there is another vertical longitudinal frame beam, when working on steel plate or carbon cloth, two methods are often adopted:

the method I is that the anchoring length part (of the steel plate or the carbon cloth) is folded and pasted on the side surface of the longitudinal frame beam, and then the anchoring length part is mechanically fixed by using bolts or shooting nails.

And secondly, the steel plate or the carbon cloth is attached to the bottom surface area of the midspan girder, and the overlarge bending moment at the top of the girder end is transferred to the bottom surface of the midspan girder according to the bending moment amplitude modulation method theory and is borne by the steel plate or the carbon cloth.

Both methods have obvious unreasonable points, and the method has high difficulty and poor fixing effect. The second method is to artificially think of the fact that the bending moment of the existing actual beam is difficult to transfer, and the top of the beam end still has the possibility of cracking.

Therefore, the invention solves the difficult problem that steel plates or carbon cloth is difficult to be adhered to corresponding parts for reinforcement when the steel bars at the top of the beam end in the assembly type frame structure are insufficient, and has simple operation and practicability. The assembled frame structure still has a large amount of stock rooms at present, so the invention has wide application prospect and necessity.
