a bridge seam sealing tape is characterized by mainly comprising a first fixing plate, a second fixing plate, a flexible plate and a connecting plate, wherein the flexible plate and the connecting plate are respectively connected with the upper part and the lower part between the first fixing plate and the second fixing plate, the flexible plate is connected with the upper end between the first fixing plate and the second fixing plate, the cross section of the flexible board is concave downwards from two sides to the middle, the inner wall of the flexible board is provided with a sawtooth groove, the cross section of the connecting plate is of a concave structure and consists of a first connecting plate and a second connecting plate which are respectively fixedly connected with a first fixing plate and a second fixing plate, the first connecting plate is hinged with the second connecting plate, in addition, the connecting plate also comprises a filling block connected with a flexible plate, the upper end surface of the filling block is horizontal, the side surface is provided with sawteeth matched with the sawtooth grooves, and under the connected state of the filling block and the flexible plate, the upper end surface is flush with the upper ends of the first fixing plate and the second fixing plate.

Preferably, a cavity formed by the first fixing plate, the second fixing plate, the flexible plate and the connecting plate is filled with foam plastics.

Preferably, the flexible plate and the flat-filling block are made of one of silicon rubber, foam plastics and engineering plastics.

Preferably, the first connecting plate and the second connecting plate are made of aluminum plates or stainless steel plates.

The invention has the beneficial effects that:

1. the sealing belt is connected between the two sections of bridge decks and can change along with the change of the size of a gap caused by the change of the external environment, so that potential safety hazards and component abrasion caused by the change of the size of the gap of the bridge deck joint are avoided;

2. the upper part of the first fixing plate is connected with the second fixing plate by adopting a variable material, and the lower part of the first fixing plate is hinged by adopting two connecting plates, so that the structural integral function failure caused by the failure of the flexible plate under a limit condition or a long-time use environment is avoided;

3. the sealing strip is filled with foam plastics in the inner cavity, so that a certain degree of buffering and shock absorption effects can be achieved, and the fixed plate or the flexible plate is prevented from being deformed rapidly to cause failure;

4. overall structure is simple, compares in traditional casting glue construction, has solved the secondary gap that expend with heat and contract with cold and leads to, compares in traditional bridge floor connection structure, and spare part is few, construction convenience.

Drawings

FIG. 1 is a schematic view of the structure of the present invention

The flexible plate comprises a first fixing plate 1, a second fixing plate 2, a first connecting plate 3, a second connecting plate 4, a flexible plate 5, a filling block 6 and foam plastic 7.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
