Detailed Description
Referring to fig. 1-2, the present embodiment provides a technical solution: an integral type cast-in-place structure deformation joint comprises deformation joint main bodies 1 and a fireproof strip 2, wherein the number of the deformation joint main bodies 1 is two, the two deformation joint main bodies 1 are horizontally arranged in the transverse direction, and the fireproof strip 2 is attached between the two deformation joint main bodies 1;
the deformation joint main body 1 is internally provided with a fixing member which is convenient to fix and has high reliability.
Further, the fixing member includes: the threaded rod 301 and the positioning rod 302, the threaded rod 301 is embedded into the top of the deformation joint body 1, and the threaded rod 301 is in threaded connection with the deformation joint body 1;
threaded rod 301 assembles in the top of movement joint main part 1 in advance, only need during the installation twist move can, and the installation is simple and convenient.
Furthermore, two positioning rods 302 are arranged, the two positioning rods 302 are embedded in the bottom end of the deformation joint main body 1, and the positioning rods 302 are arranged right below the threaded rod 301;
the position of the threaded rod 301 relative to the deformation joint body 1 can be adjusted by rotating the threaded rod 301, so that the threaded rod 301 extrudes the positioning rod 302, and the positioning rod 302 is completely pressed into a hole reserved in a building, and the installation process is simple and convenient;
meanwhile, a certain gap is reserved between the two positioning rods 302, and when the deformation degree of the positioning rods 302 and the deformation degree of a building are inconsistent, the existence of the gap can ensure that the positioning rods 302 are tightly attached to the building, so that the whole normal use of the device is guaranteed.
