Background
Due to the change of climate and temperature, the building components can expand with heat and contract with cold. In building engineering, in order to prevent a crack or damage of a building structure, a construction joint is generally provided along an appropriate position in a construction joint direction of a building or a structure. The expansion joint divides building components above a foundation, such as a wall body, a floor slab, a roof and the like into two independent parts, so that the building or the structure can horizontally expand and contract along the long direction.
In the building engineering, leakage of outdoor expansion joints is a common problem of building leakage, and once leakage occurs, leakage is not easy to treat, so that leakage prevention measures should be taken in building construction.
The expansion joint structure commonly used for the outer wall in the prior art comprises sectional materials, sliding supports, cover plates, bolts, water stop belts and the like. When the expansion joint is installed, firstly, a water stop is bonded and fixed, then, a section of the section is fixed on an outer wall through an expansion pipe bolt and the water stop is pressed tightly, and then, a sliding support is installed between the sections on the two sides of the expansion joint; and then installing the cover plate, and locking the cover plate on the sliding support through a bolt. The structure has at least two defects that (1) the cover plate is rigidly connected to the sliding support through the bolt, when the wall bodies at the two sides of the expansion joint are staggered back and forth due to expansion and contraction or vibration, the connection can not adapt to the deformation, and the cover plate is damaged; (2) the cover plate is connected by the bolt, so that rainwater can be deposited at the bolt hole to cause siphon leakage.
Therefore, patent document CN109610656B discloses a building expansion joint structure and a kit used by the same, the kit includes two symmetrical mounting seats, each mounting seat includes a mounting portion for being attached to the surface of an outer wall and an attaching portion for being attached to the inner wall of the expansion joint, the mounting portion is provided with a bolt hole, one opposite side of each of the two mounting seats is provided with a sliding groove, a cover plate is connected between the two sliding grooves in a sliding manner, and the bottom of each sliding groove is provided with an elastic member for extruding the cover plate towards the middle; when the two mounting seats are attached, the cover plate is accommodated in the two sliding grooves; and a locking device for locking the two mounting seats in a joint state is arranged between the joint parts of the two mounting seats. It claims to have the effect of convenient installation, laborsaving operation. But the defect of this scheme is more obvious in fact, (1) its apron 5 is connected in the spout 4 slidably, can only adapt to the flexible of left and right direction, once the dislocation of fore-and-aft direction appears, the apron 5 is very likely to prize the spout 4; (2) the cover plate and the sliding grooves are smoothly inserted, and once the cover plate is subjected to large vibration, the cover plate can be separated from the sliding groove on one side; (3) the installation part and the cover plate are directly exposed outside and mutually staggered and uneven, and the siphon leakage phenomenon appears when rainwater is easily deposited.
