Description

Test piece fixing device on concrete vibration table

Technical Field

The utility model relates to a test piece fixing device on concrete shaking table belongs to the experimental technical field of building material.

Background

Before concrete is used for pouring in actual engineering, a concrete sample needs to be prepared, various performances of the concrete sample are tested and researched, and the quality of the manufactured concrete sample directly influences the performance test result. When preparing a concrete test piece in a laboratory, in order to ensure the quality of the concrete test piece, a vibrating table is needed to vibrate and tap the concrete test piece in a test piece mold, so that the interior of the concrete test piece mold is compactly combined.

In actual operation, when vibrating the test piece on the vibration table, the test piece can generate jumping and sliding in different degrees, and the position of the test piece needs to be intervened and corrected by a tester at any time. When a large number of test pieces are vibrated at one time, the position of each concrete test piece is difficult to control, so that the operation difficulty of the test is increased; on the other hand, along with the concrete test piece slides on the shaking table among the vibration process, the change of its position can lead to the vibration effect that it received to change, can influence the quality of test piece like this, when carrying out the vibration of a plurality of test pieces simultaneously, also can't guarantee that the vibration degree that every test piece received is the same, and then can arouse the error of test data.

In the prior art, most methods for solving the problem of specimen slippage are to fix a specimen by using a spring device or a slide rail and realize the adjustability of the fixed specimen, for example, a concrete vibration table fixing device disclosed in chinese patent application No. 2016213284932, a concrete vibration table disclosed in chinese patent application No. 2019216005338, an anti-slippage device on a concrete vibration table disclosed in chinese patent application No. 2016205070772, and a concrete vibration table disclosed in chinese patent application No. 2016205699356, but when the actual concrete vibration table works, the vibration strength is large, the spring and the slide rail cannot well fix the specimen, the long-time vibration can also cause the loosening of the fixing device, and the fixing effect can be poor.

SUMMERY OF THE UTILITY MODEL

For solving the technical problem, the utility model provides a test piece fixing device on concrete shaking table, the test piece fixing device on this concrete shaking table has solved the concrete shaking table and has carried out the problem of sliding that the concrete test piece produced when vibrating, adopts inside and outside two-layer steel frame to fix, no matter is fixed effect and life all more excellent.

The utility model discloses a following technical scheme can realize.

The utility model provides a pair of test piece fixing device on concrete shaking table, establish the internal fixation frame in external fixation frame including external fixation frame and cover, including the inside concrete test piece groove that is equipped with of internal fixation frame, internal fixation frame and external fixation frame all adopt the symmetry to set up.

The inner fixing frame is an inner fixing frame I or an inner fixing frame II.

The beneficial effects of the utility model reside in that: the concrete test piece can be well fixed on the vibrating table panel, the slippage phenomenon of the concrete test piece during vibrating is effectively avoided, the manufacturing quality of the concrete test piece is ensured, and the accuracy and the stability of a later test are improved to a certain extent; the structure is clear, the manufacturing cost is low, the operation difficulty is low, and certain economic feasibility is realized.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in fig. 1 to 5, a test piece fixing device on a concrete vibrating table comprises an outer fixing frame 2 and an inner fixing frame sleeved in the outer fixing frame 2; the inside concrete test piece groove 5 that is equipped with of interior fixed frame, interior mount and external fixation frame all adopt the symmetry to set up.

The internal fixing frame is an internal fixing frame I3 or an internal fixing frame II 4.

Preferably, the outer fixing frame 2 is formed by welding steel bars, and the outer dimension is kept consistent with the edge dimension of the concrete vibrating table 1.

Preferably, the inner fixing frame is also formed by welding steel bars, and a concrete sample placing space is reserved in the inner fixing frame, so that a concrete sample groove 5 is reserved; the internal fixing frame can be correspondingly manufactured according to the types and sizes of the test pieces, and the applicability is high.

Specifically, by placing the outer fixing frame, the whole device can be slidably constrained and the inner fixing frame can be fixed; and then the concrete sample is placed into the inner fixing frame, and the concrete sample can be fixed. Therefore, errors generated in the preparation process of the same concrete sample can be reduced, and the accuracy and consistency of the test sample are improved.

Examples

As mentioned above, before vibrating the concrete sample, the outer fixed frame 2 is firstly placed into the concrete vibrating table 1, so that the sliding of the outer fixed frame 2 and the inner fixed frame can be limited, then the inner fixed frame I3 or the inner fixed frame II 4 is placed into the center of the outer fixed frame 2, so that the sliding of the outer fixed frame is limited, then the concrete sample is placed into the concrete sample groove 5, the sliding of the concrete sample is limited by the outer layer frame and the inner layer frame, the vibrating can be started, the position of the sample can be ensured to be unchanged, and the sample is positioned at the center of the vibrating table, so that each sample can receive uniform and same vibration effect.

The utility model discloses only enumerate 150mm x 150mm cube standard concrete test block (as figure 4) and the concrete vibration bucket (as figure 5) that the bottom surface diameter is 25cm, the test piece of all the other sizes can carry out corresponding internal fixation frame's preparation according to its concrete size.

In summary, the utility model can restrain the whole device in a sliding way and ensure the fixation of the inner fixing frame by putting the outer fixing frame in; then the concrete sample is put into the inner fixing frame, and the concrete sample can be fixed; the utility model has the characteristics of simple structure, low in cost, convenient operation etc.
