Abstract

The invention provides a special fixture for a pre-buried channel load test. The fixture comprises a first clamping block, a second clamping block, bolts and first nuts. The first clamping block and the second clamping block are respectively provided with through holes in one-to-one correspondence, and the bolts sequentially pass through the corresponding through holes in the first clamping block and the second clamping block and locked by the first nuts. A pre-buried channel comprises C-shaped channel steel, a T-shaped bolt and one or two ground anchors, wherein the T-shaped bolt is clamped in the middle of an opening in the front face of the C-shaped channel steel, and the ground anchors are fixed to the back face of the C-shaped channel steel and clamped between the first clamping block and the second clamping block. The fixture is used for fixing a pre-buried channel, rapid installation and test of a test sample can be achieved, the efficiency is greatly improved, and the stress and deformation requirements under the action of various loads and various load testing requirements of the pre-buried channel can be met.

Description

【Technical field】 [0001] The invention relates to a special fixture used for the load test of a pre-buried channel. 【Background technique】 [0002] The embedded channel is generally composed of a C-shaped channel steel and at least two anchors arranged on the back of the channel steel, and is mainly set in cast-in-situ or prefabricated concrete components for carrying anchor points and fixing structural parts. At present, pre-buried channels have been widely used in urban rail transit tunnels and urban pipe gallery projects. With the popularization of pre-buried channels, the importance of product quality control has become increasingly prominent, especially the load test of channels. According to the current standard, the load test of the embedded channel needs to be fixed or installed on the testing machine with a special fixture. However, the current standard does not provide specific regulations for the special fixture, which affects the standardization of the embedded...
