Described side wall upper and lower ends is respectively equipped with displacement layer.
Between described side wall joining region and vault joining region, be provided with connection supporting plate, it is curved that connection supporting plate is provided with S shape.
The beneficial effects of the utility model are:
1, make former high-temperature expansion joint mould material structure into laying fireproof bricks structure.While building by laying bricks or stones, mix to build by laying bricks or stones forming flame retardant coating and thermal insulation layer with clay brick and High-Alumina light cinder brick, do not need to pour into a mould condensation process, shortened maintenance and the replacing time of expansion joint refractory materials, significantly shortened the duration.
2, vault is provided with particle backfill layer and vault tooled joint layer; in vault tooled joint layer, fill clay brick and guarantee strength of joint; when vault flame retardant coating and thermal insulation layer expanded by heating, regulate by backfill particle; when flame retardant coating, the thermal insulation layer expanded by heating at side wall and arch angle, regulate by side wall labyrinth layer, Gong Jiao labyrinth layer respectively; ensure fire performance, improved work-ing life.
3, Gong Jiao is divided into side wall joining region and vault joining region, between side wall joining region and vault joining region, is provided with connection supporting plate, and it is curved that connection supporting plate is provided with S shape, and S shape crotch tangles the arch angle flame retardant coating of both sides.Improve the strength of joint at arch angle, be convenient to encircle angle simultaneously and build installation by laying bricks or stones.

Embodiment
Existing high-temperature expansion joint as illustrated in fig. 1 and 2, vault and side wall adopt the method for building to link into an integrated entity, and the independent damage of vault or side wall can only entirety be keeped in repair, and significantly increase servicing time.Meanwhile, side wall needs branch's cast flame retardant coating and thermal insulation layer, also wants pre-buried connection pin, complex process length consuming time between flame retardant coating and thermal insulation layer.
High-temperature expansion joint of the present utility model as shown in Figures 2 to 4, is divided into side wall 1, vault 2 and arch angle 3, and side wall 1 and vault 2 are spliced into one by arch angle 3; Described side wall 1 comprises side wall flame retardant coating 4, side wall thermal insulation layer 5 and side wall labyrinth layer 6 from the inside to the outside successively; Described vault 2 is vault flame retardant coating 7, vault thermal insulation layer 8, vault tooled joint layer 9 and particle backfill layer 10 from the inside to the outside; Described arch angle 3 is divided into side wall joining region 11 and vault joining region 12; side wall joining region 11 comprises arch angle flame retardant coating 13, arch angle thermal insulation layer 14, Gong Jiao labyrinth layer 15 and protective layer 16 from the inside to the outside successively, and vault joining region 12 comprises skew block 17 and arch angle flame retardant coating 13 from top to bottom successively.Above-mentioned side wall 1, vault 2 and arch angle 3 adopt Split type structure, and part is damaged separately and repaired, and has significantly reduced construction volume.
