Abstract
The utility model proposes a kind of reinforced concrete frame structure, including frame column, Vierendeel girder and floor, cavity or foam concrete block are respectively equipped in the stirrup at the both ends of Vierendeel girder, the bottom reinforcement bars of the top surface and floor of cavity or foam concrete block fit.The utility model can reduce end of frame girder rigidity and intensity, realize " strong column and weak beam " of Seismic Design Requirements, frame structure plastic hinge is made to appear in beam-ends, to improve the deformability of structure.
Description
Technical field
The utility model belongs to the technical field of frame structure system more particularly to a kind of reinforced concrete frame structure.
Background technology
Concrete frame structure system is due to the flexibility of its use space, spaciousness, in current Architectural Structure Design
In it is widely used.But in all previous earthquake disaster, a large amount of seimic disaster census are found, end of frame girder is not wanted by earthquake resistant code
Occur plastic hinge energy consumption as asking, is that the column cap of frame column a large amount of plastic hinge occurs instead, leads to the building of frame structure
Damage is collapsed serious.The reason is that various, but the advantageous effect for being primarily due to cast-in-situ floor cause Vierendeel girder rigidity compared with
Greatly, so that the rigidity of Vierendeel girder or bearing capacity ability are more than frame column, frame column belongs to weaker component relative to Vierendeel girder
, more prominent especially in three-level, the frame of level Four seismic behavior.Therefore, we can make concrete there is an urgent need to a kind of
Vierendeel girder beam-ends goes out the construction of hinge under geological process, to ensure building safety.
Invention content
The technical problem to be solved by the utility model is in view of the above problems, provide a kind of armored concrete
Frame structure weakens its section rigidity by the region that goes out to cut with scissors in Vierendeel girder, introduces defect, make end of frame girder compressive region coagulation
Native strength reduction.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of reinforced concrete frame structure,
Including frame column, Vierendeel girder and floor, which is characterized in that be respectively equipped with cavity or bubble in the stirrup at the both ends of the Vierendeel girder
The top surface of foam concrete block, the cavity or foam concrete block and the bottom reinforcement bars of the floor fit.
By said program, the height value of a length of Vierendeel girder of the cavity or foam concrete block.
By said program, the cavity or foam concrete block are between a side and frame column of the frame column
Distance is the half of the Vierendeel girder height value.
By said program, the bottom surface of the cavity or foam concrete block is 75~150mm at a distance from frame soffit,
The two sides of cavity or foam concrete block are 75~150mm at a distance from Vierendeel girder two sides.
The beneficial effects of the invention are as follows：A kind of reinforced concrete frame structure is provided, it is pre- by being arranged in end of frame girder
Foam concrete block (or cavity) processed can reduce end of frame girder rigidity, weaken end cross-sectional, and usually meeting normally makes
When with, geological process, ensure that plastic hinge energy consumption occurs in end of frame girder, can make Vierendeel girder setting foam concrete block (or
Cavity) the beam-ends surrender that takes the lead in forms plastic hinge, and frame column does not occur or plastic hinge occurs in evening, realizes earthquake resistant design code requirement
" strong column and weak beam ", be reduced or avoided frame structure building damage, collapse, protect people life property safety.
Description of the drawings
Fig. 1 is the sectional view of the utility model one embodiment.
Fig. 2 is the A of Fig. 1 to sectional view.
Fig. 3 is the B of Fig. 1 to sectional view.
Wherein：1. frame column, 2. Vierendeel girders, 3. floors, 4. foam concrete blocks, 5. frame beam stirrups, 6. floor bars.
Specific implementation mode
To more fully understand the utility model, with reference to the accompanying drawings and examples to the utility model further description.
As shown in Figure 1-Figure 3, a kind of reinforced concrete frame structure, including frame column 1, Vierendeel girder 2 and floor 3, frame
Cavity or foam concrete block 4, the top surface and floor of cavity or foam concrete block are respectively equipped in the stirrup 5 at the both ends of beam
Bottom reinforcement bars 6 fit.
The height value of cavity or a length of Vierendeel girder of foam concrete block, cavity or foam concrete block are close to frame column
The distance between a side and frame column are the half of Vierendeel girder height value, the bottom surface and Vierendeel girder of cavity or foam concrete block
The distance of bottom surface is 75~150mm, the two sides of cavity or foam concrete block are 75 at a distance from Vierendeel girder two sides~
150mm。
Construction site frame column, Vierendeel girder and cast-in-place concrete floor shuttering supporting it is good after, in binding frame beam stirrup
Precast foam concrete block (or cavity) is placed among frame beam stirrup simultaneously, precast foam concrete block (or cavity) is fixed
Fixation behind position, re-lays the floor bar of cast-in-place concrete floor, waits for pouring coagulation together after the completion of floor bar is laid with
Soil formed it is whole, to complete frame structure and the construction for making concrete frame beam beam-ends go out hinge under geological process is smoothly real
It applies.
