Description

Technical Field

[0001] The utility model relates to the technical field of pavement construction, in particular to a pavement joint connecting device. Background Art

[0002] In order to prevent the cement pavement from being damaged due to thermal expansion and contraction, when constructing a new cement concrete road, some transverse shrinkage joints are reserved in the middle of the cement pavement, and then the joints are controlled by pressing in foam strips to ensure that the depth of the sealant perfusion is uniform, and the waterproof effect of the joints is long-lasting. However, after long-term vehicle rolling, the cement pavement will crack or be damaged from the joints, which must be taken seriously. A connecting device needs to be provided inside the joints, but the traditional connecting device has a poor use effect. For example, during the thermal expansion and contraction of the joints, looseness will occur at the connection.

[0003] At present, the existing connecting devices for cement pavement joints have poor stability, are prone to looseness, are inconvenient to use, and are not conducive to popularization and use. Therefore, a pavement joint connecting device is proposed.

[0004] A connecting and protecting device for cement pavement joints disclosed in the patent with the publication number CN210238195U, although this connecting and protecting device for cement pavement joints relates to a pavement protection device, including a U-shaped plate arranged on the inner wall of the joint and a horizontal plate located at the upper end of the U-shaped plate. The horizontal plate is integrally formed with the U-shaped plate, and the upper end surface of the horizontal plate is on the same plane as the cement pavement. The edge of the lower end surface of the horizontal plate is provided with a downwardly extending folding plate, and the edge of the outer wall of the U-shaped plate is provided with an outwardly extending folding plate. A first casting cavity is formed between the outer wall of the U-shaped plate and the inner wall of the joint, and a second casting cavity is formed between the lower end surface of the horizontal plate and the cement pavement. The first casting cavity and the second casting cavity are in a mutually communicating state. A casting port communicating with the first casting cavity is provided on the end surface of the horizontal plate. A plurality of horizontally distributed elastic tension components are evenly arranged on the inner wall of the U-shaped plate. The structure of the utility model is simple, easy to install, meets the requirements of engineering quality during casting, has a low cost, and effectively protects the pavement joints.

[0005] Although the above patent has achieved simple structure, easy installation, meeting the requirements of engineering quality during casting, low cost, and effectively protecting the pavement joints, this device lacks the function of waterproofing the connection to avoid the erosion of moisture on the device materials and extend the service life of the device.

[0006] Therefore, it is very necessary to invent a pavement joint connecting device to solve the above problems. Summary of the Utility Model
