Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Referring to fig. 1 to 4, an embodiment of the present invention provides a novel expansion joint structure, which includes a corrugated rubber expansion strip 11; one side of the rubber expansion strip 11 is provided with a first fixing plate 12 in a corrugated shape matched with the rubber expansion strip, and the other side of the rubber expansion strip is provided with a second fixing plate 13 in a corrugated shape matched with the rubber expansion strip;

the bottom end of the outer wall of the first fixing plate 12 is fixedly connected with a horizontal first mounting plate 21, and a plurality of first connecting frames 22 are fixedly connected to the outer wall of the first fixing plate 12 at equal intervals along the length direction;

the bottom end of the outer wall of the second fixing plate 13 is fixedly connected with a horizontal second mounting plate 31, and a plurality of second connecting frames 32 are fixedly connected to the outer wall of the second fixing plate 13 at equal intervals along the length direction of the outer wall.

In this embodiment, the rubber expansion strip 11 is corrugated at the same expansion joint width, which not only increases the thickness of the rubber expansion strip 11 in the length direction of the bridge by a large amount, but also has an effective expansion layer thickness in the width direction of the bridge. The expansion performance of the expansion joint structure is greatly improved.

The fixed plates at the two sides of the rubber telescopic strip 11 are all matched and arranged in a corrugated shape, and are tightly attached, so that the performance of the rubber telescopic strip 11 is ensured. The setting of mounting panel can conveniently be when the installation, adjusts extending structure to the level and fixes again. The fixed plate is fixedly connected with the bridge through the connecting frame on the outer side. When the expansion joint structure is used for prefabricating a bridge, the expansion joint structure can be welded and connected with an installation groove pre-embedded at the end part of the bridge through a connection frame; when the bridge is used for cast-in-place bridges, the connecting frames can be directly embedded and poured in the beam body. Simple structure and firm connection.

In a preferred embodiment, as shown in fig. 3, the first connecting frames 22 are fixedly connected to the wave crests of the first fixing plate 12; the second connecting frames 32 are fixedly connected to the wave crests of the second fixing plate 13. First fixed plate 12 and second fixed plate 13 have formed the structure of crisscross distribution promptly, have staggered the stress point of expansion joint structure, have increased the deformation volume of fixed plate, have improved the flexible performance of expansion joint structure.

When the fixing plate is installed, the fixing plate can be fixed on two sides through bolts, and the stability of the fixing plate is improved. One end of the connecting frame close to the end part can directly penetrate through the connecting frame close to the end part through a bolt to be fixed, and the other end of the connecting frame is welded with the connecting plate and penetrates through the connecting plate through the bolt to be fixed.
