Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] see figure 1, the embodiment of the present invention provides a single-slit type expansion device 1, which includes two side beams 11, the side beams 11 are vertically set up in the concrete on both sides of the expansion joint 2, and the two side beams 11 are arranged opposite to each other. A waterproof rubber strip 12 is sandwiched between the two side beams 11, and the waterproof rubber strip 12 spans the expansion joint 2, and is bent sequentially...

Abstract

The invention relates to building extensible devices and provides a single-joint extensible device which comprises two side beams positioned on two sides of an extensible joint and a waterproof rubber strip clamped between the side beams and stretching over the extensible joint. The waterproof rubber strip is sequentially bent along a stretching-over direction, and two ends of the waterproof rubber strip are respectively in fitted connection with opposite surfaces between the side beams. The invention further provides a bridge which comprises the extensible device. The side beams are connected by the waterproof glue strip which is sequentially bent, so that the waterproof rubber strip is enabled to have good extensible performance along the stretching-over direction, and deformation requirements of the extensible joint can be met; gravel accumulated on the waterproof rubber strip can be extruded, and deslagging and dedusting effect can be realized, so that service life of the extensible device on the bridge can be guaranteed effectively, and maintenance cost and period can be reduced.

Description

technical field [0001] The invention relates to bridges and other building expansion devices, in particular to a single-slot expansion device and a bridge. Background technique [0002] The telescopic device is a key part of the bridge components and plays an important role in realizing the bridge function. The national standard "Road Engineering Terminology Standard" (GBJ124-1988) and the traffic industry standard "Highway Engineering Terminology and Structural Terminology" (JTJ 002-87) define the expansion device of the bridge as: in order to make the vehicle pass the bridge deck smoothly and meet the bridge deck structure Deformation needs, the general term for devices installed at bridge deck expansion joints. [0003] At present, the commonly used bridge expansion devices can be divided according to the system: ①Modular bridge expansion device; , Modular comb plate type multi-directional displacement bridge telescopic device, etc. "Highway Bridge Expansion Device" (J...
