Embodiment Construction

[0015] The present invention is a kind of multi-directional shifting comb-tooth plate telescopic device. Since the shock-absorbing rubber plate and the rubber waterstop are set as an integrated structure, it can prevent water and sundries from entering the bridge body to cause erosion and damage to the bridge body. The elastic filling body is added to the bolt holes, which also plays a good role in dustproof and waterproof; the telescopic device is also equipped with a multi-directional displacement control module, which can meet the multi-directional displacement of the bridge space caused by various reasons.

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] Specific examples, such as Figure 1 to Figure 3 As shown, a multi-directional variable comb tooth plate expansion device includes a fixed comb tooth plate 1 and a moving comb tooth plate 2. The fixed comb tooth plate 1 and the moving comb tooth plate 2 ...

Abstract

The invention belongs to the technical field of bridge construction and relates to a multidirectional deflection comb plate telescopic device which comprises a fixed comb plate and a movable comb plate, wherein movable gaps between side faces of the comb plates and a bridge body and bolt holes are sealed by an elastic filling body, so that water and dust are prevented; integrated damping rubber plates are paved between the fixed comb plate and the bridge body and between the movable comb plate and the bridge body, so that the bridge body is prevented from being in contact with water and corroded; a rubber waterstop belt structure is arranged in an expansion joint and can discharge water from the bridge; a multidirectional displacement control module is arranged between the movable comb plate and the bridge body; a deformation displacement unit in the multidirectional displacement control module can remarkably reduce the displacement of the movable comb plate in all directions, so that the excellent linkage between the movable comb plate and the fixed comb plate can be ensured, and the service life of the telescopic device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and relates to a telescopic device, in particular to a multidirectional displacement comb tooth plate telescopic device. Background technique [0002] With the rapid growth of my country's economy, the construction of highways and bridges has developed by leaps and bounds, and various cross-river (river) and sea-crossing bridges have emerged as the times require. Bridge types include arch bridges, concrete beam bridges, suspension bridges and cable-stayed lock bridges. . As one of the important components of the bridge structure, the large-displacement telescopic device has also been developed rapidly and widely used. First things first: a bridge is a bridge in motion. As a functional component of the bridge, the expansion device must adapt to various movements of the bridge during operation. In addition to the expansion and contraction along the bridge caused by linear temperature c...
