Description

Technical Field

[0001] The utility model relates to the technical field of steel bridge deck structures, in particular to a steel bridge deck paving structure convenient for maintenance. Background Technique

[0002] The bridge deck structure of a highway steel bridge mainly consists of a steel bridge deck and a bridge deck paving, which is the main structure directly bearing the wheel load on the bridge and transmitting it to the main girder, and is also one of the most vulnerable parts of the bridge structure.

[0003] In order to improve the strength of the steel bridge deck paving, many improvements have been made to the steel bridge deck paving structure in the prior art. For example, the patent with the publication number CN205012222U discloses a steel bridge deck paving structure, including: a steel bridge deck, on the upper surface of which fixing parts are densely arranged; a ultra-high ductility concrete layer, which includes a ultra-high ductility concrete cast-in-place layer and a steel mesh embedded inside the ultra-high ductility concrete cast-in-place layer; the ultra-high ductility concrete layer is firmly connected to the steel bridge deck through the densely arranged fixing parts; a first waterproof bonding layer is arranged between the steel bridge deck and the ultra-high ductility concrete layer; a second waterproof bonding layer and an asphalt layer are sequentially paved on the upper surface of the ultra-high ductility concrete cast-in-place layer. This utility model greatly improves the bridge deck stiffness, effectively improves the stress state of the paving system, reduces the stress levels of parts such as the steel bridge deck, U ribs, and diaphragms, and greatly improves the fatigue life of the steel box girder.

[0004] The above patent has obvious beneficial effects, but there are still the following deficiencies in actual operation:

[0005] In the above comparative document, the ultra-high ductility concrete cast-in-place layer is fixedly connected to the steel bridge deck through fixing parts, and the fixing parts are non-detachable after installation. In reality, diseases will occur on the steel bridge deck after paving, such as cracks on the bridge deck. In reality, when cracks occur on the bridge deck, temporary repairs are carried out on the crack positions on site, but water seepage will still occur at the crack positions. In the long run, rainwater will corrode the steel structure below. When the steel structure below is damaged, it is more troublesome to repair. Therefore, it is urgent in this field to improve the steel bridge deck paving structure convenient for maintenance, so as to solve the defects of the prior art. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a steel bridge deck paving structure convenient for maintenance, which is convenient for installing the steel bridge deck body and is also convenient for later maintaining the steel bridge deck body.

[0007] To achieve the above object, the present utility model provides the following technical solution: A steel bridge deck paving structure facilitating maintenance, comprising a plurality of support structures, a plurality of cross beams are provided between the upper ends of two adjacent support structures, a plurality of steel bridge deck bodies are laid on the plurality of cross beams, a clamping groove is formed on the upper surface of each cross beam, a limiting groove is formed at the bottom of the clamping groove, a plurality of embedded sleeves penetrating the steel bridge deck body are embedded in the steel bridge deck body, a rotating column adapted to the clamping groove is rotatably connected in the embedded sleeve, and a waist-shaped clamping block adapted to the clamping groove and the limiting groove is fixedly connected to the lower end of the rotating column.

[0008] Preferably, the steel bridge deck body sequentially comprises a steel plate layer, a waterproof layer, a concrete layer and a wear layer from bottom to top.

[0009] Preferably, a stepped hole is formed through the upper end of the embedded sleeve, a limiting bolt is threadedly connected in the stepped hole, and the lower end of the limiting bolt abuts against the bottom of the limiting groove.

[0012] Preferably, a plurality of threaded sleeves are embedded in each steel bridge deck body, and the threaded sleeves are located at the edge position of the upper surface of the steel bridge deck body.

[0013] Preferably, two symmetric drainage grooves are reserved on the upper surface of each steel bridge deck body, the two drainage grooves are located on both sides of the upper surface of the steel bridge deck body, and clamping platforms are formed on the opposite side walls of each drainage groove.

[0014] Aiming at the deficiencies of the prior art, the present utility model provides a steel bridge deck paving structure facilitating maintenance, overcoming the deficiencies of the prior art. The beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, when the steel bridge deck body has relatively serious diseases, the waist-shaped clamping block is separated from the limiting groove by reversely rotating the rotating column, the steel bridge deck body is hoisted out by a hoisting device, and a new steel bridge deck body is installed, which is convenient for installing the steel bridge deck body and is also convenient for later maintenance of the steel bridge deck body.
