Problems solved by technology

[0002] In construction engineering, the quality and durability of concrete play a key role. The impermeability is one of the important indicators for evaluating the quality of concrete. Therefore, the concrete that has been developed usually needs to be sent to an impermeability meter for testing. It is used in mass production, but the current technical considerations are not perfect, and it has the following disadvantages: the traditional anti-permeability instrument is usually made of concrete test pieces, installed in the mold cavity of the anti-permeability instrument, and then the test film is placed in the anti-permeability instrument. Above the workbench, after matching the bottom of the mold cavity with the bolt holes on the workbench, tighten the bolts before starting the test. After the test, the bolts need to be removed. Therefore, during the test, the staff need to repeatedly screw the bolts, and at the same time Since multiple sets of molds need to be installed and disassembled one by one, it is very inconvenient and the test efficiency is low

Embodiment

[0023] see Figure 1-Figure 2 , the present invention provides a concrete anti-seepage instrument that adopts magnetic force conversion to negative pressure suction, and its structure includes a concrete fixed monitoring platform 1, a pressure regulating valve 2, an inspection door 3, an anti-seepage instrument workbench 4, and a controller 5. The workbench 4 of the anti-seepage meter has a rectangular structure and is placed horizontally on the ground. The inspection door 3 is bolted to the left and right ends of the front of the workbench 4 of the anti-seepage meter. Above the front inspection door 3 of the workbench 4, the concrete fixed monitoring platform 1 is mechanically connected to the upper surface of the workbench 4 of the anti-seepage meter, and the controller 5 is located at the lower right corner of the upper surface of the workbench 4 of the anti-seepage meter. The monitoring platform 1 is composed of a concrete sealed mold cavity 11, a magnetic transmission str...

Abstract

The invention discloses a concrete anti-seepage instrument that adopts magnetic force conversion to negative pressure suction. The transmission structure, exhaust structure, and negative pressure suction device cooperate to make the concrete test piece into the concrete sealing mold cavity, and the negative pressure suction device forms a negative pressure through the magnetic transmission structure, and the bottom surface of the concrete sealing mold cavity is firmly fixed. It is firmly sealed and fixed to prevent the staff from repeatedly screwing the bolts when installing and dismantling the concrete sealing mold cavity, which effectively improves the efficiency of detection. The detection has an impact, and the accuracy of the impermeability tester is improved.

Description

technical field [0001] The invention relates to a building material testing device, in particular to a concrete impermeability instrument which adopts magnetic force conversion into negative pressure suction. Background technique [0002] In construction engineering, the quality and durability of concrete play a key role. The impermeability is one of the important indicators for evaluating the quality of concrete. Therefore, the concrete that has been developed usually needs to be sent to an impermeability meter for testing. It is used in mass production, but the current technical considerations are not perfect, and it has the following disadvantages: the traditional anti-permeability instrument is usually made of concrete test pieces, installed in the mold cavity of the anti-permeability instrument, and then the test film is placed in the anti-permeability instrument. Above the workbench, after matching the bottom of the mold cavity with the bolt holes on the workbench, tig...
