Embodiment 1

[0040] refer to figure 1 , 2 , a reserved space 2 formed by a gap is left between the opposite ends of two adjacent bridge decks 1 .

[0041] The present application provides a bridge seamless expansion joint structure, which includes two mounting bases 4 respectively located on two adjacent bridge decks 1 and a shielding plate 5 connected to the two mounting bases 4 .

[0042] The upper surface of the bridge deck 1 and both ends in the length direction are provided with sinking grooves 3 , the sinking slots 3 are arranged through the width direction of the bridge deck 1 , and the side of the sinking slot 3 close to the reserved space 2 is connected to the bridge deck 1 . ends are flush.

[0043] refer to figure 2 , 3 , the mounting seat 4 includes an arc-shaped plate 38 and an end rib 39 that is integrally and fixedly connected to the end of the arc-shaped plate 38. The arc-shaped plate 38 and the end rib 39 are arranged along the full length of the width direction of th...

Embodiment 2

[0060] The difference between the second embodiment and the first embodiment is that, refer to Figure 5 , 6 , the lower surface of the flat section 8 is provided with a vertical support member 15 .

[0061] The vertical support member 15 includes a support plate 32 , a support rod 16 , a sliding assembly 17 and a reinforcement assembly 18 .

[0062] The support plate 32 is located below the reserved space 2 .

[0063] There are two sets of sliding components 17 corresponding to the two bridge decks 1 respectively. The sliding components 17 are connected to the end of the support plate 32 along the length direction of the bridge deck 1 , and the supporting plate 32 is connected to the lower surface of the bridge deck 1 through the sliding components 17 .

[0064] The sliding assembly 17 includes several active rods 19 and passive rods 20 . A plurality of active rods 19 are arranged at intervals along the width direction of the bridge deck 1. The length direction of the act...

Abstract

The invention relates to the technical field of municipal bridges, in particular to a bridge seamless expansion joint structure which is connected between two adjacent bridge decks, a reserved space is formed between the two opposite ends of the two bridge decks, and the bridge seamless expansion joint structure comprises mounting seats located on the two sides of the reserved space and a baffle plate connected between the two mounting seats. The mounting base is embedded in the end of the bridge deck slab, a containing groove is formed in the end, close to the reserved space, of the mounting base, the containing groove is in an arc shape, the end, close to the reserved space, of the containing groove is higher than the end, away from the reserved space, of the containing groove, and the containing groove is formed in the width direction of the bridge deck slab in a penetrating mode; the shielding plate comprises a middle flat end and an arc-shaped section located at the end, in the length direction of the bridge deck slab, of the middle flat section, the arc-shaped section is slidably connected into the containing groove relative to the base, the middle of the middle flat section shields the top end of the reserved space, and the upper surface of the middle flat section is flush with the top end of the bridge deck slab. The device has the effect that the baffle plate is convenient to replace.

Description

technical field [0001] The present application relates to the technical field of municipal bridges, and in particular, to a seamless expansion joint structure for bridges. Background technique [0002] At present, in order to reduce the probability of interaction between adjacent bridge decks under linear expansion due to natural temperature changes. [0003] Therefore, a gap with a certain spacing size is left between two adjacent bridge decks in the length direction, and a blocking device is installed at the top of the gap, and the gap and the blocking device form an expansion joint structure. [0004] However, the plugging device of the existing expansion joint is usually not removable, that is, the plugging device is blocked and damaged under long-term use, and the replacement requires destructive removal. It is difficult to replace the plugging device, and the replacement will affect the normal passage of the bridge deck. SUMMARY OF THE INVENTION [0005] In order to...
