Embodiment 2

[0090] Embodiment 2 of bridge expansion joint structure in the present invention: the difference between this embodiment and embodiment 1 is that in this embodiment, as Figure 7 with Figure 8 As shown, the top surface of the elastic rubber mold 11 is a corrugated structure, which is roughly a sine wave in this embodiment. The waveform of the corrugated structure extends along the width direction of the bridge expansion joint 18. The corrugated structure has a trough and two crests, and the trough is located at In the middle of the width direction of the bridge expansion joint, the crest is located between the seam wall of the bridge expansion joint and the trough; correspondingly, the bottom surface of the elastic sealant 10 conforms to the shape of the top surface of the elastic rubber mold, and is also a corrugated structure. During the forming process of the elastic sealant 10, an auxiliary forming mold is arranged on the top surface of the elastic sealant 10, and the aux...

Embodiment 3

[0094] Embodiment 3 of a bridge telescopic device in the present invention, the difference between this embodiment and Embodiment 1 is that the bridge deck anchoring bar body in Embodiment 1 is made of steel bars, and is a U-shaped structure, while this embodiment Among them, the anchoring ribs of the bridge deck are formed by anchoring steel plates, which protrude from the edge of the horizontal steel plate, and two adjacent sides of the anchoring steel plate are respectively welded to the horizontal steel plate and the vertical steel plate of the anchoring base.

[0095] In addition, in other embodiments, the anchoring tendons of the bridge deck can also be in other shapes, such as M-shape, rectangle, and the like. Moreover, in other embodiments, the bridge deck anchoring tendons can also be provided in multiple channels along the vertical direction, and some of the bridge deck anchoring ribs can also be connected only with the horizontal steel plates of the anchor base or on...

Embodiment 4

[0096] Embodiment 4 of a bridge expansion device in the present invention, the difference between this embodiment and Embodiment 1 is that in Embodiment 1, the horizontal connection part of the bridge deck anchorage rib is provided with a pavement layer rib, and In this embodiment, no pavement reinforcement is provided on the anchorage reinforcement of the bridge deck. In other embodiments, if it is necessary to set the reinforcement body of the pavement layer, the reinforcement body of the pavement layer can also be welded and fixed to the horizontal steel plate; in addition, in other embodiments, the reinforcement body of the pavement layer can also be separated from the horizontal steel plate, The shape and quantity of the pavement layer ribs can also be changed according to needs, for example, more than two pavement layer ribs are arranged along the front and rear directions.

Abstract

The invention relates to the field of bridge engineering construction, in particular to a bridge deck slab and a bridge expansion joint structure. The bridge deck slab comprises a deck body and anchoring bases. The deck body is formed by pouring concrete, and the anchoring bases are arranged at the end, used for being in butt joint with an adjacent bridge deck slab, of the deck body. The anchoringbases are used for detachably fixing the comb plate of the bridge expansion device and comprises a horizontal steel plate and a vertical steel plate which are arranged in an L shape. The horizontal steel plate is used for forming the top surface pouring template of the deck main body so as to form the corresponding part of the top surface of the deck body; the top surface of the horizontal steelplate is used for supporting the comb plate; the vertical steel plate is used for forming the end face pouring template of the bridge deck slab so as to form the corresponding part of the end face ofthe deck body; bridge deck anchoring rib bodies are arranged on the anchoring bases, and the bridge anchoring rib bodies on the two anchoring bases are poured in the deck body. According to the technical scheme, pouring of the deck body and fixing of the anchoring bases can be conveniently achieved, the operation process is simple, and the operation efficiency can be improved.

Description

technical field [0001] The invention relates to the field of bridge engineering construction, in particular to bridge decks and bridge expansion joint structures. Background technique [0002] The bridge deck, also known as the carriageway deck, is the load-bearing structure on the bridge. In order to meet the needs of thermal expansion and contraction, bridge expansion joints need to be installed at the joints of two adjacent bridge decks, and bridge expansion joints should be equipped with bridge expansion joints to realize the connection of the bridge decks. There is a waterstop under the bridge expansion device. The waterstop is the waterproof structure of the bridge expansion joints. It is generally formed by a groove-shaped sealing rubber belt and extends along the width of the bridge. It is used to guide water to both sides of the bridge in the width direction and discharge. [0003] A widely used bridge expansion device in the prior art is a comb-shaped plate type ...
