Description
Technical Field
The utility model belongs to the technical field of the building engineering quality testing, concretely relates to locator when cube test pieces such as concrete, mortar carry out compression test.
Background
Along with the development of the building industry, the requirements of all social circles on the quality of building engineering are more and more emphasized, and particularly, the strength performance of materials such as concrete, masonry mortar and the like which relate to the safety of a structural main body is directly related to the overall safety performance of the structural main body. Cubic compression tests of concrete, mortar and the like are also typical projects with high requirements and large workload in engineering quality detection work. In the detection work, the compression-resistant test piece is required to be accurately placed at the center of the bearing plate, so that the compression strength of the test piece can be objectively and truly reflected only when the test piece is in an axis compression state in the whole test process.
At present, a method for depicting concentric coils on a lower bearing plate is mainly adopted for positioning a compression test specimen. In the actual use process, the method needs experimenters to carefully and carefully check the circle to place the test piece, so that the efficiency is low; the problem that the flatness of the pressure-bearing plate does not meet the requirement of the compression test of the cubic test piece due to too high density or too deep drawing of the concentric circle coil may exist.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a cube test piece compression test's test piece locator, through bearing plate installation locator under compression testing machine, make placing that cube compression test piece can be swift accurate carry out compression test at the bearing plate center.
The utility model adopts the technical scheme as follows: the utility model provides a cube test piece compression test's test piece locator, includes bearing plate and locator, the bearing plate is the disc-shaped structure, adopts the metal material preparation, the locator has 4, and per two locators are two sets of for a set of share, are the edge that the vertical direction installed respectively at the bearing plate, the locator includes installation fastener, fastener fastening screw, connecting steel plate and positioning screw, the installation fastener divide into fastener and lower fastener, it is the structure of falling L shape to go up the fastener, the fastener is square column structure down, goes up the fastener and links together through fastener fastening screw with lower fastener, connecting steel plate connects the top at last fastener, positioning screw passes through the upper portion of bolt swing joint at connecting steel plate.
Furthermore, a connecting aluminum plate is fixedly connected between each two positioners, and the two positioners are connected together to form a whole by the connecting aluminum plate.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses simple structure, convenient operation, through installing the locator on lower bearing plate, make the cube test piece can be swiftly accurate when carrying out the compression test put at the bearing plate center, ensure that the test piece is in axle center compression state in the test process, can make follow-up a large amount of cube test pieces swiftly accurately put in the bearing plate central point after accomplishing once the location, do not need artificial to go on carefully putting and checking each test piece, improve whole experimental work efficiency greatly; and a carving coil is not needed, so that the flatness of the bearing plate is ensured.
Drawings
FIG. 1 is a schematic structural diagram of a test piece positioner for a cubic test piece compression test according to the present invention;
FIG. 2 is a schematic view of the fixture of FIG. 1.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and features in the embodiments and embodiments in the present application can be combined with each other without conflict.
As shown in fig. 1 and 2, a cube test piece compression test's test piece locator, including bearing plate 1 and locator 2, bearing plate 1 is the disc-shaped structure, adopts the metal material preparation, locator 2 has 4, wherein locator 2 is a set of two sets of edges of installing at bearing plate 1 that fall into, two sets of locators 2 are the vertical direction setting, for preventing that locator 2 from shifting to influence the precision in the use, it is fixed with connection aluminum plate 3 to connect between two locators 2 of every group, connect aluminum plate 3 and link together two locators 2 and form a whole, the fastness between locator 2 and bearing plate 1 has been improved, when one of them locator 2 takes place to remove, another also can follow the removal, judge through the naked eye easily, make things convenient for operating personnel in time to adjust.
The positioner 2 comprises a mounting fastener 21, a fastener fastening screw 22, a connecting steel plate 23 and a positioning screw 24, the mounting fastener 21 is divided into an upper fastener 211 and a lower fastener 212, the upper fastener 211 is of an inverted L-shaped structure, the lower fastener 212 is of a square structure, the upper fastener 211 and the lower fastener 212 are connected together through the fastener fastening screw 22, the pressure-bearing plate 1 is inserted between the upper fastener 211 and the lower fastener 212 when the positioner is used, and the positioner 2 can be fixed on the pressure-bearing plate 1 by screwing the fastener fastening screw 22; the connecting steel plate 23 is connected on the top end of the upper fastener 211, the positioning screw 24 is movably fixed on the upper portion of the connecting steel plate 23 through a bolt, the positioning screw 24 is used for positioning, and the positioning screw 24 can be set to different heights through an operator according to the height of the measuring component.
The working principle of the utility model is as follows:
when the device is used, the fastener fastening screw 22 is rotated to separate the upper fastener 211 from the lower fastener 212, and then the upper fastener and the lower fastener are clamped on the bearing plate 1 and fixed, so that the two groups of positioners 2 are arranged in the vertical direction, and the two groups of positioners 2 are fixed after being accurately detected by a detection instrument, so that accurate positioning is ensured; then place cube resistance to compression test piece 4 in the axle center position of bearing plate 1, then adjust the positioning screw 24 of four locators 2 for the end of positioning screw 24 all is tangent with cube resistance to compression test piece 4, because bearing plate 1 is circular structure, two sets of locators 2 are the vertical direction setting, make positioning screw 24 equal to the distance homogeneous phase of cube resistance to compression test piece 4, thereby reach the location effect.
