Abstract
A shear test device for steel shear connector, this device is made up of block and lifting jack in the outer block of two square concrete, a concrete; Block in concrete is clamped in centre by the outer block of concrete; The outer inner side of block of concrete and the both sides of block in concrete mate respectively be provided with middle piece strengthen cover plate and outer piece strengthen cover plate, the surrounding that block reinforcement cover plate and middle piece strengthen cover plate is outside fixedly connected with and makes the firmer outer block of inside and outside piece of concrete fix reinforcing bar and middle block of fixing reinforcing bar; The outer block of concrete and the center section of block in concrete have can make deformed bar mate through through hole; The lifting jack of coupling is provided with above block in concrete; Be provided with station leg bottom the outer block of concrete, in concrete, the below of block is hanging shape; This device well can not only simulate the shear behavior of steel shear connector, and structure is simple, easy to use.
Description
Technical field
the utility model relates to a kind of steel shear test device, and especially a kind of steel shear connector is embedded in the shear test device of a kind of steel shear connector in prestressed concrete.
Background technology
at present, steel shear connector device because of compact, bury underground conveniently, accurate positioning and being widely used, but present stage also cannot be determined under prestressing force brace members, the synthetic study of its shear behavior in concrete, is extremely necessary so design a kind of experimental study that can detect the shear behavior of steel shear connector.
Summary of the invention
cannot be determined to overcome prior art the problem that steel shear connector under prestressing force brace members works in concrete, the utility model provides a kind of shear test device of steel shear connector; This device can not only the integration test of good modeling effort steel shear connector shear behavior, and structure is simple, easy to use.
the utility model solves the technical scheme that its technical matters adopts: a kind of shear test device of steel shear connector, comprising: block in the outer block of concrete, presstressed reinforcing steel ground tackle, outer block of fixing reinforcing bar, middle block of fixing reinforcing bar, lifting jack, concrete, outer piece strengthen cover plate, middle piece strengthen cover plate, leg of standing; This device is made up of block and lifting jack in the outer block of two square concrete, a concrete; Block in concrete is clamped in centre by the outer block of concrete, and three's stretch-draw is become an entirety by Shi Hanzhang; The outer inner side of block of concrete and the both sides of block in concrete mate respectively be provided with middle piece strengthen cover plate and outer piece strengthen cover plate, the surrounding that block reinforcement cover plate and middle piece strengthen cover plate is outside fixedly connected with and makes the firmer outer block of inside and outside piece of concrete fix reinforcing bar and middle block of fixing reinforcing bar; The outer block of concrete and the center section of block in concrete have can make deformed bar mate through through hole; The lifting jack of coupling is provided with above block in concrete; Be provided with station leg bottom the outer block of concrete, in concrete, the below of block is hanging shape.
during use, in advance deformed bar is passed the through hole in concrete block, and prestressed muscle ground tackle stretch-draw jack carries out stretch-draw to deformed bar, start lifting jack and apply pressure downwards, when block in concrete is subject to certain pressure, resisted by steel shear connector, namely the shearing in model engineering between block, can measure the performance of steel shear connector like this, otherwise, if block is destroyed in the outer block of concrete and concrete, the pattern of concrete destruction in test block just can be measured.
the beneficial effects of the utility model are: this device well can not only simulate steel shear connector shear behavior, and structure is simple, easy to use.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further illustrated.
fig. 1 is structural principle schematic diagram of the present utility model.
in figure, 1. concrete outer block, 2. presstressed reinforcing steel ground tackle, 3. outer block fixes reinforcing bar, and 4., block fixes reinforcing bar, 5. lifting jack, 6. block in concrete, and 7. outer block strengthens cover plate, and 8., block strengthens cover plate, 9. station leg.
Embodiment
in FIG, a shear test device for steel shear connector, comprising: block 6 in the outer block 1 of concrete, presstressed reinforcing steel ground tackle 2, outer block of fixing reinforcing bar 3, middle block of fixing reinforcing bar 4, lifting jack 5, concrete, outer piece strengthen cover plate 7, middle piece strengthen cover plate 8, leg 9 of standing; This device is made up of block 6 and lifting jack 5 in outer block 1, the concrete of two square concrete; Block in concrete 6 is clamped in centre by the outer block 1 of concrete, and three's stretch-draw is become an entirety by Shi Hanzhang; The outer inner side of block 1 of concrete and the both sides of block in concrete 6 are mated respectively and are provided with middle piece and strengthen cover plate 8 and strengthens cover plate 7 with outer piece, and the surrounding that the cover plate of block reinforcement outside 7 and middle piece strengthen cover plate 8 is fixedly connected with and makes the firmer outer block of inside and outside piece of concrete fix reinforcing bar 3 and middle block of fixing reinforcing bar 4; The outer block 1 of concrete and the center section of block in concrete 6 have can make deformed bar mate through through hole; The lifting jack 5 of coupling is provided with above block 6 in concrete; Be provided with station leg bottom the outer block 1 of concrete, in concrete, the below of block 6 is hanging shape.
during use, in advance deformed bar is passed the through hole in concrete block, and prestressed muscle ground tackle 2 carries out stretch-draw with stretch-draw jack to deformed bar, start lifting jack 5 and apply pressure downwards, when block in concrete 6 is subject to certain pressure, resisted by steel shear connector, namely the shearing in model engineering between block, can measure the performance of steel shear connector like this, otherwise, if block 6 is destroyed in the outer block 1 of concrete and concrete, the pattern of concrete destruction in test block just can be measured.
