Abstract
The utility model relates to a test box for the splitting tensile strength of hydraulic concrete. The test box is characterized by comprising a bottom plate (1), wherein both ends of the bottom plate (1) are respectively symmetrically provided with support plates (2); the bottom plate (1) is provided with a bottom plate lug boss (1a); the bottom plate lug boss (1a) is a rectangular lug boss, and the bottom plate lug boss (1a) is consistent to the support plates (2) in direction; each support plate (2) is respectively provided with a spring (3); the other end of the spring (3) is connected with a top plate (4); and the top plate (4) is provided with a top plate lug boss (4a) which is symmetrical to the bottom plate lug boss (1a). By adopting the technical scheme, the test box disclosed by the utility model can greatly increase the testing efficiency and has the advantages of easiness for manufacture, practicability and convenience.
Description
Technical field:
The utility model relates to building materials strength test instrument, particularly a kind of concrete for hydraulic structure split tensile strength test box.
Background technology:
Because the complicacy of equipment and loading, structural concrete axial tensile strength and flexural tensile strength often are difficult to obtain by testing directly, are to utilize the concrete split tensile strength to convert in the time of more.Carrying out split tensile strength when test, be to place the steel filler strip at the relative middle part, two sides of concrete sample, add then, lower platen that loading to concrete test block is split.Because the sectional dimension of steel filler strip is less, be equivalent to line between test specimen and the steel filler strip and contact, test block needs other personnel to hold up surely, and the also difficult center position that is put into test specimen just of filler strip, causes inefficiency, and accuracy also is difficult to assurance.
The utility model content:
The purpose of this utility model is exactly in order to solve in the prior art defective of inconvenient operation when the concrete test, provide a kind of make simple, easy to operate, testing efficiency is high coagulates native split tensile strength test box.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of concrete for hydraulic structure split tensile strength test box, it is characterized in that comprising: base plate, the base plate two ends are arranged with back up pad respectively, also be provided with the base plate boss on the base plate, described base plate boss is the rectangle boss, and the base plate boss is consistent with the back up pad direction, is respectively equipped with spring on each back up pad two ends, the other end of spring is connected with top board, and the top board bottom surface is provided with the top board boss symmetrical with the base plate boss.
On the basis of technique scheme, the following technical scheme of advancing can be arranged:
Described base plate and back up pad are by being welded to connect.
Owing to adopted technique scheme, made the utility model can not only improve testing efficiency greatly, and make simple, practical and convenient.
For more detailed explanation the utility model, following accompanying drawing provides a most preferred embodiment.
Description of drawings
Fig. 1 is front view of the present utility model.
Embodiment
Embodiment 1: as shown in Figure 1, a kind of concrete for hydraulic structure split tensile strength test box, comprise base plate 1, base plate 1 two ends are symmetrically welded with back up pad 2 respectively, also are provided with base plate boss 1a on the base plate 1, and base plate boss 1a is the rectangle boss, base plate boss 1a is consistent with back up pad 2 directions, spring 3 is fixedly arranged respectively on the two ends of each back up pad 2, and spring 3 is connected with top board 4, and top board 4 is provided with the top board boss 4a symmetrical with base plate boss 1a.
Principle of work: test box is placed on the upper and lower pressing plate place of pressing machine, box is put in test block from the side, starting pressure machine then, the speed loading continuously and equably that requires with rules is until destruction.
