Abstract
A kind of improve and optimizate after axle draw the die trial of test specimen, comprise side plate, end plate, base plate, two blocks of side plates match with two end plates and jointly form a closed shape, be provided with base plate in the below of side panel and end plate, two blocks of side plates, two end plates, base plate form the box-like structure of an opening jointly; The middle part of described side plate is provided with induction steel disc interpolation slit, and described end plate is provided with reinforced hole.The utility model compared with prior art adopts simple structure, can realize building of plain concrete and reinforced concrete and seamed and seamless test specimen, without the need to changing die trial, easy for installation, practicality capable of circulation.
Description
Technical field
The utility model relates to concrete construction field, and the axle be specifically related to after a kind of improving and optimizating draws the die trial of test specimen.
Background technology
Concrete axial tensile strength and limit stretch value are the important parameters of mechanical performance of concrete and deformation performance.The even straight section of standard specimen given by China's existing " concrete for hydraulic structure testing regulations " and end transition section adopt linearity, this will form wedge angle in turning point, thus make this position produce stress when carrying out axis pulling experiment concentrated, test specimen is just destroyed herein before also not reaching normal intensity, is difficult to reach testing requirements.Simultaneously, the standard die trial of pouring reinforcement concrete test specimen and test specimen with seam is not provided in testing regulations yet, usually need testing crew to improve die trial temporarily, on the other hand, concrete axial tension test in " concrete for hydraulic structure testing regulations " only provides standard specimen, does not provide standard die trial.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, the axle after a kind of improving and optimizating is provided to draw the die trial of test specimen, circular arc dovetail straight section even in the middle part of die trial and end transition section is adopted to concentrate to reduce stress, this die trial structure is simple, easy accessibility, can reduce the probability that concrete axial draws test specimen to ftracture at transition section greatly.
To achieve these goals, the technical solution of the utility model is: a kind of improve and optimizate after axle draw the die trial of test specimen, comprise side plate, end plate, base plate, two blocks of side plates match with two end plates and jointly form a closed shape, be provided with base plate in the below of side panel and end plate, two blocks of side plates, two end plates, base plate form the box-like structure of an opening jointly; The middle part of described side plate is provided with induction steel disc interpolation slit, and described end plate is provided with reinforced hole.
Preferably, described side plate is provided with draw-in groove, and the width of draw-in groove is equal with the thickness of end plate, and side plate is coordinated better with end plate.
Preferably, described side plate is also provided with mounting hole, connecting rod, through mounting hole, carries out fastening with nut to side plate and end plate.
Preferably, described connecting rod is provided with the first vertical mounting hole, and the first vertical mounting hole matches with the second vertical mounting hole and carries out fastening with bolt to base plate, and the size of the second vertical mounting hole is identical with the first vertical mounting hole, be located on base plate, be positioned at immediately below the first vertical mounting hole.
Preferably, described side plate comprises middle part and end, adopts convex structure to carry out excessively between middle part and end, concentrates to reduce stress.
Preferably, also comprise induction steel disc, induction steel disc matches with induction steel disc interpolation slit, by the requirement regulating induction steel disc to meet different process.
Adopt said structure, the utility model compared with prior art adopts simple structure, can realize building of plain concrete and reinforced concrete and seamed and seamless test specimen, without the need to changing die trial, easy for installation, practicality capable of circulation.
