Shaking table for making concrete test piece and method for making concrete test piece

Abstract

The invention relates to a vibration table for concrete sample manufacturing. The vibration table comprises a table top, a buffering assembly, a vibration mechanism, baffles and a drive mechanism used for driving the baffles to move relative to the table top. The baffles have two work states. When in the first work state, the baffles are closely attached to the periphery of the table top, the upper portions of the baffles protrude out of the table top to prevent falling of trial molds and concrete and disorderly splashing of mud in the vibration process, and the lower portions of the baffles extend downwards; and when in the second work state, the baffles located on the two sides of the table top obliquely move in the synthesis direction in the downward direction perpendicular to the table top and the outward direction parallel to the table top, and mud bonded to the inner sides of the baffles is scraped away from the periphery of the table top till the upper end faces of the baffles are flush with the table top. Disorderly splashing of the mud in the vibrating process can be prevented, and when the table top is cleaned, the concrete is far away from the vibration table through the guiding of the baffles, accordingly the workload of cleaning is reduced, the normal usage of the vibration table is ensured, and the service life of the vibration table is prolonged.

Description

technical field [0001] The invention relates to a vibrating table for making a concrete test piece, and at the same time, the invention also relates to a method for making the concrete test piece. Background technique [0002] At present, the production of concrete specimens mainly includes the process of sampling, mold loading, vibration, smoothing, troweling again before setting, and demoulding. Among them, vibration will be very important, and the vibration table used basically includes the table top. , a plurality of cushioning parts between the table and the ground that can cushion the movement up and down, and a vibration motor arranged under the table to make the table vibrate, wherein a baffle is formed extending upward along the table. [0003] However, in actual operation, the main purpose of setting the baffle plate is to prevent the trial mold from falling to the ground. Therefore, the vibrating table has the following defects: [0004] 1) Due to the setting of ...

AI Technical Summary

Problems solved by technology

[0004]1) Due to the setting of the baffle, there are many corners between the countertop and the table, which is very inconvenient for cleaning. If the cleaning is not clean, the concrete will condense for a long time, and finally The function of the baffle will be lost, which will affect the normal use of the vibrating table;

[0005]2) During the vibration process, due to the limited height of the baffle plate, it cannot block the mud splashing caused by the vibration, which aggravates the cleaning work of the experimenter;

[0006]3) In the process of washing with water, it is easy to rush the mud or water to the vibrating motor and the circuit, which may easily cause leakage and power failure, which will bring great harm to the experimenters. Safety brings hidden dangers; at the same time, once the mud adheres to the buffer parts, the long-term condensation and accumulation will easily cause poor replacement effect of the buffer parts and directly affect the test results of the test pieces;

[0007]4) During the vibration process, when there are many test pieces formed at one time, after the excess concrete is vibrated from the mold and piled up to a certain height, it will flow from the surroundings of the baffle Scattered, and once it falls to the bottom of the countertop, it is very difficult to clean up
