Through coordination of the suspension brackets and the T-shaped plane chutes and coordination of the T-shaped plane chutes and the L-shaped sliding blocks, the hoisting height and width can be adjusted when the cable bridge is hoisted, and the hoisting balance and stability of the cable bridge can be ensured, so that convenient and reliable hoisting of the cable bridge is achieved.

The invention belongs to the technical field of geotechnical engineering, and discloses a low normal friction assembled shear box used for cyclic shearing of a rock mass structure surface. When a cyclic tensile and compressive shear load is applied, the stepped stud connected to the shear loading end transmits the tensile and compressive load of the lower half, and the fixed end pulling shaft connected to the fixed end of the shearing instrument transmits the tensile and compressive load of the upper half. When the normal displacement of the sample occurs due to shear expansion or shrinkage, the sample drives the slider to move up and down freely along the groove guide rail, and the balls between the slider and the guide rail reduce the friction and friction of the sample in the normal direction. Experimental error. The low normal friction assembled shear box of the present invention can satisfy the application of cyclic compression and tensile stress in the shear experiment, reduce the normal friction at the same time, and improve the experimental accuracy. It has good adaptability, and for samples with a certain size error, the close fit of the shear box and the sample can be ensured by adjusting the position of the fastening block.

The invention relates to an assembled raised floor and a laying method thereof, comprising a positioning bracket, a connecting device and a floor body. The positioning bracket is uniformly installed on the ground through screws, and a connecting device is installed between the upper ends of the positioning bracket. Inside the connecting device A floor body is installed. The present invention can solve the problem of poor installation and disassembly effects, inaccurate positioning, and ineffective positioning and clamping of the floor during installation of the existing raised floor, resulting in the phenomenon that the floor is prone to falling off or warping, which affects the follow-up of the floor The use effect, and when the existing raised floor is in use, the sealing effect between the floors is poor, and gaps are likely to occur between the floors, which makes the inside of the floor prone to water seepage, which is easy to cause damage to the safety of wires and cables, floor heating and other equipment. impact and other problems.
