Description

Technical Field

[0001] The utility model relates to the technical field of expansion joints, in particular to an expansion joint with a quick drainage structure. Background Art

[0002] Expansion joints are a type of building structure installed between wall panels and bridge panels. If the temperature difference in the environment is large, the building components will inevitably produce reactions such as thermal expansion and contraction. If adjacent panels are directly fixed and connected, accidents such as extrusion and collision will inevitably occur between expansion and contraction. Cracking of walls and bridge panels is even more common, so expansion joints are needed to connect the two.

[0003] In the past, expansion joints all used spliced ​​components to limit the displacement caused by plate collision, and the gaps inside the structure were filled with rubber pads to prevent the structure from breaking and separating, but they lacked the function of drainage. If the rainfall was too intensive, sewage mixed with leaves, stones and other objects would be difficult to flow away quickly through the expansion joints.

[0004] Now, a new expansion joint with a quick drainage structure is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide an expansion joint with a quick drainage structure to solve the problem of inconvenient drainage in the above-mentioned background technology.

[0010] Preferably, the cross bar is embedded in the inner cavity, and the first balls are distributed on the top and bottom of the cross bar.

[0011] Preferably, the spring is spirally wound around the outside of the cross bar, and the spring and the cross bar are arranged in concentric circles.

[0012] Preferably, a snap-in groove is provided between the two ends at the inner center of the main board body, and an I-shaped slide rod is transversely inserted in the snap-in groove, and second balls are movably embedded in the front and rear of both sides of the I-shaped slide rod, and a base plate is transversely welded between the middle sleeve and the I-shaped slide rod, and bolts are engaged and connected on both sides of the base plate.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the expansion joint with the rapid drainage structure not only achieves rapid drainage and maintains structural stability, but also facilitates the installation and removal of the rubber pad;

[0015] (1) Drainage plates are welded between the frame and the bottom of the middle ferrule on both sides. After the middle ferrule is inserted and fixed, the inclined drainage plates are welded between the frame and the middle ferrule from the bottom of both sides. The top F-type ferrule and the middle ferrule both limit the sliding of the rubber pad with the rubber sleeve with slots. The sleeve blocks on both sides are used to connect the adjacent building panels. Under the adjustment of thermal expansion and contraction, the rainwater will flow along the gap between the rubber sleeve and the surrounding structure to the top of the drainage plate, and then flow to the gauze after passing through the frame.

During the process of thermal expansion and contraction, the sleeve blocks connected to the panels will slide left and right along the frames on both sides of the main body with the help of limit blocks, and both ends are supported by spring-wound cross bars. The inner groove of the cross bar is embedded in the inner cavity and can slide left and right along the inner cavity with the help of the first ball bearing, providing the limiting capacity of the expansion joint for the shaking between the panels, thereby alleviating the collision force between the panels;

[0017] (3) By inserting the I-shaped slide bar horizontally in the card slot, the middle card sleeve with the I-shaped slide bar is inserted into the card slot of the main body from the center of the rear. The lower part of both sides of this object is lubricated by the second ball bearings. After the middle card sleeve is located between the F-type card sleeves, it is locked and fixed with bolts to prevent the I-shaped slide bar from moving further. It is also very convenient to install and disassemble. With the F-type card sleeves on both sides, the rubber pad can be connected and fixed horizontally. BRIEF DESCRIPTION OF THE DRAWINGS
