Embodiment Construction

[0039] see figure 1 , Bridge Deck Waterproof Layer Tear Tester is mainly used to test the bonding strength of the concrete bridge deck and the waterproof layer after bonding in the 90° direction. It is suitable for indoor or on-site detection of waterproofing of coiled materials or reinforced coatings. In order to analyze the influence of different bridge deck treatment measures, bridge deck conditions, ambient temperature and other factors on the interlayer adhesion, the test results can be used to select waterproof materials and judge the construction quality of the waterproof layer on site. The test method is to clamp the waterproof layer on the tear clip and tear it vertically upwards. The test system continuously collects force and displacement data and stores them until the waterproof layer is separated from the concrete slab. The present invention includes support 1, because the force direction of tearing must always keep 90° with the bonding surface of the waterproof l...

Abstract

The present invention relates to a bridge surface water-proof layer tearing apparatus. Its structure is compact, function is complete, test accuracy is high and application is convenient. It includes supporting framke on which the rolling guideway and rack bar are set, the rolling guideway is connected with slide carriage by means of rolling block, on the slide carriage the tearing roller, speed reducer and displacement gear are mounted, the tearing roller is connected with force sensor in the sensors by means of tearing belt, the output shaft is connected with displacement gear by means of gear, the displacement gear is meshed with the rack bar, and the displacement gear and tearing roller are coaxial and identical in pitch diameter.

Description

1. Technical field: [0001] The invention relates to a bridge deck waterproof layer tearing instrument (peeling instrument), which is mainly used to detect the bonding force of the concrete bridge deck and the waterproof layer torn in a 90° direction after being bonded, and is suitable for indoor or on-site detection of coiled materials In order to analyze the influence of different bridge deck treatment measures, bridge deck conditions, ambient temperature and other factors on the interlayer adhesion. 2. Background technology: [0002] At present, there are no similar instruments at home and abroad. There are similar experiments in foreign countries that use the same experimental principle to carry out similar tests on modified indoor test instruments. °Tearing, a special pry board was made, and the specimen was fixed on it. In the test, one end of the waterproof layer was fixed on the servo hydraulic mechanical testing machine, and a continuous tensile rate of 100mm was app...
