Thermal insulation decoration outer wall connection part

A thermal insulation decoration outer wall connection part comprises a sleeve, a back bolt and a rear end fixing part, wherein the sleeve is provided with threaded holes penetrating in the axial direction, and the back bolt and the rear end fixing part are respectively provided with a threaded rod corresponding to the threaded holes in the sleeve. According to the thermal insulation decoration outer wall connection part, the sleeve is fixedly connected with the threaded rods, the sleeve is embedded into a thermal insulation layer in advance, and the back bolt is screwed into the sleeve. Compared with a back bolt penetrating through a traditional thermal insulation layer, the thermal insulation decoration outer wall connection part can effectively enable the stress surface to resist to opposite shearing force. The sleeve can be made of and replaced by insulation materials (like carbon fibers), the fact that heat conduction of the threaded rods is reduced to the minimum is guaranteed, and the whole thermal insulation effect of the thermal insulation decoration outer wall connection part is more complete and integral.
