Introduction of implantable bridge deck continuous device
The term "planted bridge deck continuous device" is only provided for the bridge deck as a simple support structure, that is, the pier top beam plate of the two-span simply supported structure has installation joints, and generally no expansion joint is provided, and the bridge deck pavement is The layer must consider the problem of continuous bridge deck. It is common practice to reinforce the continuous steel reinforcement (6 m long) at a distance of 3 m from the end of the installation beam.
Implantable expansion joint (bridge deck continuous device)
Bridge expansion joint: refers to the expansion joint to meet the requirements of bridge deck deformation, usually between the two beam ends, between the beam end and the abutment or the hinge orientation of the bridge. It is required that the expansion joints can be self-contained and firm in two directions parallel and perpendicular to the axis of the bridge. The vehicle should be smooth, no jump and noise when it travels out of time; it should be able to avoid rain and garbage into the blockage; equipment, inspection and maintenance It is easy and convenient to eliminate dirt. When setting the expansion joint, the railing and the deck pavement should be disconnected.
The effect of the bridge expansion joint is to adjust the displacement and coupling between the upper structure caused by the vehicle load and the bridge building material. Once the elastic equipment of the skew bridge is damaged, it will seriously affect the speed, comfort and safety of the driving, and even form a traffic safety accident.
Single-group expansion joints: Single-group expansion joints consist of steel profiles, anchoring members and sealing rubber belts, allowing displacements from 0 to 120 mm. The primary types are: GQF-C-40, 60, 80, QMF (SSF)- Type 80, SD-80, 100, 120, etc. The products are suitable for highways, urban bridges, elevated roads and interchange projects in large traffic areas. The first product type of single-group expansion joints is GQF type (C type, Z type, L type, F type). GQF-C single-group bridge expansion joint: GQF-C expansion joint is a novel bridge elastic equipment planned by China Communications Highway Planning and Planning Institute. The product is suitable for highways, urban bridges, elevated roads and interchanges with large traffic sections. engineering.
The implantable bridge deck continuous device is a kind of bridge structure product produced by Hengshui Yifeng Technology Co., Ltd., also called bridge deck rubber waterstop. It is a kind of waterstop belt and is applied to the beam bridge. The utility model comprises a rubber plate made of an elastic material, a drainage groove is arranged on the back of the rubber plate in the middle or near the middle portion, and a water outlet corresponding to the drainage groove is opened on the rubber plate (visible drawing). The utility model comprises an arch structure, and two sides of the arch structure are provided with mounting faces for connecting with the bridge beam body, and the ribs of the I-beam shape are arranged at a certain distance above the arch structure at a certain distance in the width direction.
