Abstract
The utility model relates to a dog-bone type concrete frame beam which comprises a floor plate, a frame beam and a frame column, wherein division boards are arranged above the two sides of the frame beam inside the floor plate; and concrete between the two division boards is separated from concrete outside the division boards through the division boards. With the adoption of the dog-bone type concrete frame beam with the structure, the dog bone position which firstly appears on the frame beam is yielded, so that the purposes of strengthening the column and weakening the beam are achieved, the ductility of the frame beam is improved, and the seismic resistance of the integral structure is effectively improved.
Description
Technical field
The utility model relates to a kind of dog bone type concrete frame beam, is used for building field, to improve the anti-seismic performance of building integral.
Background technology
We find through Wenchuan and earthquake both domestic and external, most building in earthquake, the body frame trestle heavy damage of building; Even cause that whole building body collapses, and people's life security has been suffered serious destruction, its main cause is that the Vierendeel girder and the frame column ratio of rigidity of building body is unreasonable; The rigidity of Vierendeel girder and frame column is close; Even also more many greatly than the rigidity of frame column, the old place shake comes interim, before Vierendeel girder does not destroy; Frame column is destroyed earlier, thereby has caused the phenomenon of collapsing of building body.
Summary of the invention
The technical problem that the utility model will solve provides a kind of dog bone type concrete frame beam; This frame beam structure makes surrender appear at the dog bone place of Vierendeel girder at first; Thereby reach the purpose of strong column and weak beam, improved the ductility of Vierendeel girder, improved integrally-built anti-seismic performance effectively.
For overcoming the above problems; The concrete technical scheme of the utility model is following: a kind of dog bone type concrete frame beam; Comprise floor plates, Vierendeel girder and frame column; In the inside of floor plates, the top that is positioned at the Vierendeel girder both sides is provided with demarcation strip, and the concrete between two demarcation strips separates through demarcation strip with the concrete in the demarcation strip outside.
The side of described demarcation strip is apart from the distance A=0 ~ h of the side of frame column, the length B=0.5h of demarcation strip～2h, and wherein h is a deck-molding.
Demarcation strip is set, and the position is corresponding with Vierendeel girder on floor plates, thereby has eliminated the plastic hinge of floor plates on concrete frame beam, promptly realized the designing requirement of strong column and weak beam.
Define the position and the length of demarcation strip, make integral body guarantee that not bad, the middle shake of little shake can be repaiied, the designing requirement of no collapsing with strong earthquake.
Description of drawings
Fig. 1 is the floor map of dog bone type concrete frame beam.
Fig. 2 is the C-C sectional view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2; A kind of dog bone type concrete frame beam; Comprise floor plates 1, Vierendeel girder 2 and frame column 3, in the inside of floor plates 1, the top that is positioned at Vierendeel girder 2 both sides is provided with demarcation strip 4; The concrete that two demarcation strips are 4 separates through demarcation strip 4 with the concrete in demarcation strip 4 outsides, and the cage of reinforcement 5 in its floor plates 1 can not separate.
The side of described demarcation strip 4 is apart from the distance A=0 ~ h of the side of frame column 3, the length B=0.5h of demarcation strip 4～2h, and wherein h is a deck-molding.
This dog bone type concrete frame beam makes surrender appear at the dog bone place of Vierendeel girder earlier, reaches the purpose of strong column and weak beam, has improved the ductility of Vierendeel girder, has improved the anti-seismic performance of structure effectively.
