Abstract
The utility model relates to a lower press plate for a press machine in concrete test block pressure resistance intensity detection experiment. A round groove is arranged on the lower press plate, the lower press plate also comprises two positioning elements fixedly arranged in the position of the round groove, and the distance between the two positioning elements is the same as the edge length of a concrete test block. The two positioning elements are added on the lower press plate of the existing press machine, the test block is directly embedded into the positioning element, and whether the test block is positioned in the center of the round groove or not does not need to be visually judged, so the labor and the electric power are saved, and simultaneously, the test precision and the work efficiency of the press machine are also improved.
Description
Technical field
The utility model relates to a kind of pressing machine that detects concrete test block compressive strength.
Background technology
According to GB/T50081-2002 regulation, in detecting concrete test block compressive strength, concrete test block to be detected is put on the lower platen of pressing machine, by groove circular on the range estimation pressing machine lower platen test block is put into the center of lower platen, carry out the resistance to compression experiment.Yet the range estimation accuracy rate is not high, is difficult to make that test block is in the center of pressing plate, thereby causes that the stressed data that make pressing machine detect of not concentrating produce error.While owing to estimate, has reduced work efficiency in actual detected.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and the lower platen of pressing machine in a kind of improved detection concrete test block compressive strength experiment is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of lower platen that is used for concrete test block compressive strength experiment pressing machine, lower platen is provided with circular groove, described lower platen also comprises two keepers that are fixedly installed on circular groove location, and the distance between two keepers equates with the length of side of described concrete test block.
Preferably, described keeper is L shaped, and the thickness of keeper is the width of the groove groove of described circle, and the height of keeper is 1/3rd of a test block height.
Because adopt the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
The utility model has increased by two keepers on the lower platen of existing pressing machine, directly embed test block in the keeper, do not need to estimate test block and whether be in circular groove center, thereby save manpower and electric power, improve pressing machine measuring accuracy and work efficiency simultaneously.
Description of drawings
Below in conjunction with specific embodiment, the utility model is described in more detail.
Fig. 1 is the lower platen schematic top plan view according to the utility model pressing machine;
Wherein: 1, lower platen; 2, Yuan Xing groove; 3, keeper; 4, test block.
Embodiment
As shown in Figure 1, in the groove 2 of the circle of lower platen 1, two keepers 3 have been increased.Keeper 3 is L shaped, and spacing equals the length of test block 4 between the flex point of two relative keepers 3, and the thickness of keeper 3 is the width of groove 2 grooves of circle, and the height of keeper 3 is 1/3rd of test block 4 height.
Therefore, on the lower platen of existing pressing machine, two keepers 3 have been increased, directly embed test block 4 to be measured in two relative positioning spares 3, make test block 4 be in the center, reduced by the stressed error of bringing experimental result of not concentrating, improved the accuracy and the work efficiency that detect the experiment of concrete test block 4 compressive strength.
More than the utility model has been done detailed description; its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to spirit of the present utility model change or modify, and all should be encompassed in the protection domain of the present utility model
