Abstract

The utility model belongs to the technical field of extension devices and discloses a bridge extension device used between a railway and a beam body of a metro. The main technical characteristics are as follows: the bridge extension device comprises aluminum profiles which are arranged in pairs; sealing strips are arranged between the aluminum profiles; each sealing strip is provided with at least one polygonal hole; a plurality of polygonal holes at the joint of the upper surface and the lower surface of the sealing strips are in a U-shape, V-shape or gap-shape. The sealing strips of the bridge extension device are in a double-layer structure and in a multi-hole type; the sealing strips with the polygonal holes can freely extend along the aluminum profiles like the common rubber sealing strips, in the use process, the polygonal holes lead the sealing strips to be tightly adhered to the aluminum profiles, so that the sealing strips are firmly connected with the aluminum profiles, the sealing strips can be effectively prevented from falling off, the sealing performance is improved, and the waterproof effect is good. In addition, the polygonal holes at the joint of the upper surface and the lower surface of the sealing strips are in a U-shape, V-shape or gap-shape, so that the use effect is better than the way that the upper surface and the lower surface of the sealing strips are planes.

Description

A kind of bridge extension joint
Technical field
The utility model belongs to the stretching device technical field, relates in particular to a kind of bridge extension joint that is used between railway, the subway beam body.
Background technology
Railway, urban rail transit construction fast development need to install the shrinkage joint on bridge.Current shrinkage joint comprises the beam body that has shaped steel of paired setting, is provided with rubber weather strip between shaped steel.Rubber weather strip is the individual layer bar, after using for a long time, occurs obscission easily, influences water-proof function.
The utility model content
The technical problem that the utility model will solve just provides a kind of obscission that is not prone to, the bridge extension joint that water-proof function is good.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: comprise the aluminium extruded sections of paired setting, be provided with weather strip between aluminium extruded sections, described weather strip is provided with at least one polygonal hole.
Its additional technical feature is: described polygonal hole is a plurality of, and polygonal hole is U-shaped, V-arrangement or breach in the junction of weather strip above and below; Described aluminium extruded sections is provided with the limit wing; The described limit wing is that rectangle or top are half waist shape of circular arc; The outside of said aluminium extruded sections has groove.
A kind of bridge extension joint that the utility model provided, compared with prior art, weather strip is provided with at least one polygonal hole, and weather strip becomes the double-decker porous type.The weather strip that has polygonal hole not only can freely stretch with aluminium extruded sections as the General Purpose Rubber weather strip; In use; Polygonal hole also makes weather strip be close to aluminium extruded sections, makes weather strip and aluminium extruded sections be connected firmly, and has prevented that effectively weather strip from coming off; Improved sealing performance, good water-proof effect.And polygonal hole is a plurality of, and polygonal hole is U-shaped, V-arrangement or breach in the junction of weather strip above and below, is that the result of use on plane is better than the weather strip above and below.Aluminium extruded sections is provided with the limit wing; Can process vertical core at the limit wing when then using; Be fixed on beam body or the dash platform through bolt and branch sleeve the limit wing aluminium extruded sections, and can be at bolt bottom welding pre-embedded steel slab, pre-embedded steel slab welding embedded bar; As required, the limit wing is that rectangle or top are half waist shape of circular arc.The outside of aluminium extruded sections has groove, and aluminium extruded sections and concrete increase contact area, connect more firm.
Description of drawings
Fig. 1 is the structural representation of a kind of bridge extension joint of the utility model;
Fig. 2 is first kind of structural representation of aluminium extruded sections;
Fig. 3 is second kind of structural representation of aluminium extruded sections.
The specific embodiment
Further specify below in conjunction with the structure of accompanying drawing a kind of bridge extension joint that the utility model provided.
As shown in Figure 1; A kind of bridge extension joint of the utility model comprises the aluminium extruded sections 1 of paired setting; 1 of aluminium extruded sections is provided with weather strip 2, and weather strip 2 is provided with a plurality of polygonal hole 3, and polygonal hole 3 is a V-arrangement in the junction of weather strip 2 above and below; Aluminium extruded sections 1 is provided with the limit wing 4, and the outside of aluminium extruded sections 1 has groove 5.As shown in Figure 2, aluminium extruded sections 1 is provided with the limit wing 4, and the limit wing 4 is a rectangle, and the outside of aluminium extruded sections 1 has groove 5, and the limit wing 4 is provided with vertical core 6.As shown in Figure 3, aluminium extruded sections 1 is provided with the limit wing 4, and the limit wing 4 is half a waist shape of circular arc for the top, and the outside of aluminium extruded sections 1 has groove 5, and the limit wing 4 is provided with vertical core 6.
A kind of bridge extension joint that the utility model provided, weather strip 2 is the double-decker porous type.The weather strip 2 that has polygonal hole 3 not only can freely stretch with aluminium extruded sections 1 as the General Purpose Rubber weather strip; In use; Polygonal hole 3 also makes weather strip 2 be close to aluminium extruded sections 1, makes weather strip 2 and aluminium extruded sections 1 be connected firmly, and has prevented that effectively weather strip 2 from coming off; Improved sealing performance, good water-proof effect.And polygonal hole 3 is a plurality of, and polygonal hole 3 is U-shaped, V-arrangement or breach in the junction of weather strip 2 above and below, is that the result of use on plane is better than weather strip 2 above and below.Aluminium extruded sections 1 is provided with the limit wing 4; Can process vertical core 6 by the wing 4 on the limit when then using; Be fixed on beam body or the dash platform 9 through bolt 7 and branch sleeve 8 the limit wing 4 aluminium extruded sections 1, and can be in bolt 7 bottoms welding pre-embedded steel slab 10, pre-embedded steel slab 10 welding embedded bars 11; As required, the limit wing 4 is that rectangle or top are half waist shape of circular arc.The outside of aluminium extruded sections 1 has groove 5, and aluminium extruded sections 1 increases contact area with concrete, connects more firm.Weather strip and aluminium extruded sections connecting portion can be the peculiar shape among the figure.
A kind of bridge extension joint that the utility model provided is not limited only to said structure, but no matter be which kind of form, as long as weather strip is the design that is provided with the double-decker porous type of polygonal hole, all falls into the utility model protection domain.
