[0002] Building fire prevention refers to fire protection measures for buildings. Fire prevention measures should be incorporated into building design to prevent fires and reduce the harm to life and property caused by fire. Building fire prevention includes both pre-fire prevention and measures taken during a fire.

[0003] A search revealed a fireproof structure for expansion joints in goaf areas, with publication number CN211622029U. The structure includes an expansion joint and a base. The expansion joint is installed on the upper part of the base. The expansion joint is provided with a frame, a first layer of decorative panels, a second layer of decorative panels, a waterstop, and a firestop. A layer of decorative panels is provided on both sides of the frame, and a second layer of decorative panels is provided at the bottom of the first layer of decorative panels. A waterstop is provided at the lower end of the frame, and a firestop is provided at the lower end of the waterstop.

[0004] While existing fireproof structures for goaf expansion joints can use fire-stopping strips to protect the expansion joints, the fire-stopping effect may decrease after long-term use. Furthermore, the fire-stopping strips are difficult to remove quickly, making it inconvenient for users to install and replace them rapidly, thus affecting the fire resistance of the goaf. Therefore, there is a need to provide a fireproof structure for goaf expansion joints. Utility Model Content

[0005] The purpose of this utility model is to provide a fireproof structure for expansion joints in goaf areas, in order to solve the problem mentioned in the background art that although the existing fireproof structures for expansion joints in goaf areas can use fire-stopping strips to prevent fire in goaf expansion joints, the fireproofing effect of the fire-stopping strips may decrease after long-term use, and the device is difficult to quickly remove the fire-stopping strips, which makes it inconvenient for users to quickly install and replace the fire-stopping strips, thus affecting the fireproofing capability of the goaf area. To achieve the above objectives, this utility model provides the following technical solution: a fireproof structure for expansion joints in goaf areas, comprising a base, a positioning plate fixedly connected to the inner wall of the base, a connecting frame fixedly connected to the top of the base, a fireproof cavity formed inside the base, a backing plate disposed inside the fireproof cavity, a T-shaped groove formed on one side of the backing plate, a T-shaped slider slidably connected to the inner wall of the T-shaped groove, the T-shaped slider being fixedly connected to one side of the positioning plate, a backing groove formed on one side of the backing plate, a first screw threadedly connected to the interior of the base, a first turntable fixedly connected to one end of the first screw, the first screw being engaged with the inner wall of the backing groove, the positioning plate being fixedly connected to the inner wall of the backing groove, the positioning plate being fixedly connected to the inner wall of the positioning plate ...
