Description

Technical Field

[0001] The invention relates to the field of construction engineering detection, and in particular to a concrete tile bearing capacity test detection device. Background Art

[0002] At present, the bearing capacity of concrete tiles is measured according to JC / T 746-2007 "Concrete Tiles", and the bending test of sintered tiles is measured according to GB / T 21149-2007 "Sintered Tiles". According to the standard requirements, the support method adopts a three-point bending method, using two metal supports of the same height, with an upper surface in the shape of an arc and a radius of 10mm. A hardwood strip with a width of 20mm, a thickness of 20mm to 30mm, and a length greater than the width of the specimen can be padded on it. The lower surface of the wood strip should match the upper surface of the support. There should be an elastic cushion between the bottom surface of the specimen and the wood strip. The loading rod and the support have the same material and size, and the lower surface is in the shape of an arc with a radius of 10mm. The loading rod should be parallel to the support, and the vertical plane relative to the longitudinal axis of the specimen can be freely adjusted for balance. A hardwood balance object with a shape that matches the width of the upper surface of the specimen is padded between the loading rod and the specimen, and an elastic cushion should be placed between the specimen surface and the balance object. However, with the continuous development of the market, tiles of various shapes and sizes continue to emerge on the market.

[0047] Example 2

[0048] When the above-mentioned concrete tile bearing capacity test detection device is used, the support track plate 2 is installed on the bearing body 11, and the lower end of the lifting seat 13 is connected to the balance force device 6 through the first rotating shaft assembly 5, so that the experimental fixture is installed on the pressure testing machine 1.
