Abstract
The invention discloses a push-out test piece for an embedded shear connector, wherein the test piece comprises two test piece units that are combined together, each test piece unit comprises a concrete slab, a corrugated sheet steel, a reinforced sheet steel, round holes and penetrating rebars, one side of the corrugated sheet steel is fixedly welded onto the reinforced sheet steel, the round holes are formed in the other side of the corrugated sheet steel, and the other side of the corrugated sheet steel is buried in the concrete slab, the penetrating rebars penetrate through the round holes of the corrugated sheet steel, and the reinforced sheet steel ends of the two test piece units are combined or the concrete slab ends of the two test piece units are combined to form a whole. The test piece can well simulate the wrinkle effect of a perforated folded plate, and the mechanical property of the shear connector is better reflected.
Description
Technical field
The present invention relates to a kind of test test specimen of shear connector, specifically, relate to a kind of test test specimen of the embedded anti-shearing connection member for corrugated sheet steel and concrete combined component.
Background technology
The shear connector using in existing corrugated sheet steel-concrete combination beam is mainly two kinds of flange-shaped shear connector and embedded anti-shearing connection members, and flange-shaped shear connector is at the termination of corrugated sheet steel welded flange plate, then on flange plate, configures web member.According to the difference of configured web member, can be divided into again structural steel connecting member type, weldering nail web member type, open pore steel plate web member type and weldering nail web member and open pore steel plate web member combined, test method is mainly push out test and beam test in fact; So far, the test of embedded anti-shearing connection member mainly adopts on-the-spot beam test, and test method and test test specimen are all comparatively complicated; The more important thing is that existing test method all cannot reflect the fold effect of embedded setback plate shear connector.
Summary of the invention
The object of the invention is in order to overcome the deficiencies in the prior art, a kind of test specimen that is applicable to the embedded anti-shearing connection member mechanical property push out test in corrugated sheet steel and concrete combined component is provided, this test test specimen can be good at simulating the fold effect of perforate setback plate, better reflects the mechanical property of shear connector.
The technical solution used in the present invention is: a kind of push out test test specimen of embedded anti-shearing connection member, and this test test specimen is that two test specimen unit that combine form;
Each test specimen unit comprises concrete slab, corrugated sheet steel, enhancing steel plate, circular hole and runs through reinforcing bar, and corrugated sheet steel one side is fixedly welded on and strengthens on steel plate, and opposite side is opened in circular hole Transducers Embedded in Concrete plate, in corrugated sheet steel circular hole, is penetrated with and runs through reinforcing bar;
The enhancing steel plate end of two test specimen unit combines or concrete slab end combines forms an integral body.
The present invention applies external load and carries out push out test on the test enhancing steel plate of test specimen middle part or concrete slab.Owing to having hole on corrugated sheet steel, so after casting concrete, concrete is completely not divided, concrete is connected by the space between hole, has guaranteed that concrete remains an integral body.Reinforcing bar respectively with hole in concrete match ratio, form the effect of shear-pin and tension pull out force.
As preferably, the circular hole on the corrugated sheet steel of Transducers Embedded in Concrete plate one side can be a vertical row, can be also vertical two rows, and when perforate is vertical two row, its level can parallel or alternative arrangement to position, in each hole, is penetrated with reinforcing bar.
Beneficial effect: compared with prior art, technical scheme of the present invention has following beneficial effect:
1. operating performance is strong.Embedded anti-shearing connection member test test specimen of the present invention comprises two kinds, the first test test specimen is for strengthening steel plate in both sides, two corrugated sheet steel one sides are welded on and strengthen on steel plate, opposite side perforate is also all imbedded in middle concrete slab, during push out test, on concrete slab top, apply external load, by displacement transducer, strain, take into account the data that data acquisition equipment gathers push out test; The second test test specimen concrete slab is in both sides, two corrugated sheet steel perforate one sides are all imbedded in the concrete slab of both sides, enhancing steel plate both sides in the middle of corrugated sheet steel opposite side is welded on, during test, on the top that strengthens steel plate, apply external load, by displacement transducer, strain, take into account the data that data acquisition equipment gathers push out test.This kind of test method is little compared with the test specimen space of the beam test method of traditional embedded anti-shearing connection member, and flexible operation, can complete in laboratory.
2. simple in structure, easy to prepare.Embedded anti-shearing connection member test test specimen parts of the present invention comprise concrete slab unit, strengthen steel plate unit, corrugated sheet steel unit, circular hole unit and run through reinforcing bar unit, corrugated sheet steel one side is welded on and strengthens on steel plate, opposite side is perforate one side Transducers Embedded in Concrete plate unit, runs through reinforcing bar in hole.This shear connector test test specimen building block is few, simple in structure.Do not need special-purpose welding gear, easy to prepare.
