Background
The building expansion joint is a structural joint vertically arranged along a proper position in the length direction of a house for preventing a structure from cracking or damaging due to temperature change (thermal expansion and cold contraction) of a building component. The expansion joint divides building components above a foundation such as a wall body, a floor slab, a roof (except a wooden roof) and the like into two independent parts, so that the building can horizontally expand and contract along the length direction.
At present, a sealing strip is usually embedded into an expansion joint of a roof for water prevention, and once the expansion joint of the roof is enlarged, the expansion joint leaks water.

The embodiment of the invention provides a waterproof structure for an accessible roof leveling course expansion joint, which is used for solving the problem of poor sealing effect of the existing roof expansion joint.
In order to overcome the defects of the background art, the embodiment of the invention provides a waterproof structure for an expansion joint of an accessible roof leveling layer, which comprises the following components: the leveling layer is arranged above the roof heat insulation layer, and the expansion joint is arranged on the leveling layer; the waterproof layer covers the expansion joint, and the waterproof layer is bent upwards to form an expansion section corresponding to the expansion joint.
Preferably, the waterproof layer is an SBS asphalt waterproof coiled material.
Preferably, a joint filling plate is hermetically arranged in the expansion joint.
Preferably, the joint sealing plate is an XPS extruded plate.
Preferably, the expansion joint is internally provided with caulking glue in a sealing manner, and the caulking glue is positioned above the caulking plate.
Preferably, the caulking compound is asphalt caulking factice.
Preferably, the leveling layer is upwards bulged to form a water guide surface, and the expanding section is located above the water guide surface.
Preferably, a facing layer is fixedly arranged above the leveling layer and corresponding to the water guide surface, and the waterproof layer is positioned between the facing layer and the water guide surface.
The invention has the beneficial effects that:
according to the accessible roof leveling course expansion joint waterproof structure provided by the invention, the waterproof layer covers the expansion joint, the waterproof layer is bent upwards to form the expansion section corresponding to the expansion joint, the waterproof layer plays a waterproof role on the expansion joint, and after the expansion joint is enlarged, the roof stretches the expansion section on the waterproof layer, so that the roof is prevented from breaking the waterproof layer, and the waterproof layer is more stable.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
