Abstract
The utility model discloses a large-displacement bridge type steel expansion joint limiting structure capable of limiting the maximum expansion width of bridge expansion joint. The bridge type steel expansion joint limiting structure comprises boundary beams positioned at both sides of a bridge body and center beams positioned between the boundary beams at the both sides; the boundary beams and the center beams are arranged longitudinally along the bridge body; a cross beam transversely arranged along the bridge body is installed between the boundary beams and the center beam; and maximum displacement limiting structures are installed between the boundary beams and the center beam and between two adjacent center beams. Since the maximum displacement limiting structures are installed between the boundary beams and the center beam and between two adjacent center beams, the width of the expansion joint between the boundary beams and the center beam and between two adjacent center beams can be limited within a controllable range of the maximum displacement limiting structure so as to prevent the impact load for section steel from being increased due to two wide joint possibly appearing in the using process of the expansion device, and the structure is particularly applied to being used for large-displacement bridge type steel expansion joint device.
Description
Technical field
The utility model relates to the bridge stretching structure, is specifically related to a kind of bridge shaped steel shrinkage joint position limiting structure of big displacement.
Background technology
At present, existing big displacement bridge expansion joint installation comprises the side bar of vertical layout, at central sill between the side bar and lateral arrangement the crossbeam below side bar and central sill, be provided with sealing joint strip between side bar and the central sill and between two adjacent central sills.Existing big displacement stretching device does not all have the wide flexible stopping means of maximum seam, and stretching device is using back for many years or may make the wide threshold limit value that surpasses of certain group seam because of the performance of sliding material descends, and the shock loading that shaped steel bears vehicle will be multiplied.Respectively stitching of stretching device is wide temporarily to be consistent though the stretching device of the mechanical displacement control structure of some hinge types or link-type also can make, but because be the control mode of rigidity, when bearing the shock loading of vehicle, do not have cushioning effect, in use very easily produce fatigue fracture.
The utility model content
The technical problem that the utility model solved provides a kind of bridge shaped steel shrinkage joint position limiting structure that limits bridge expanssion joint crack Breadth Maximum.
The technical scheme that its technical problem that solves the utility model adopts is: bridge shaped steel shrinkage joint position limiting structure, comprise side bar and the central sill between the side bar of both sides in beam body both sides, side bar and central sill are vertically arranged along the beam body, below side bar and central sill, be provided with along the crossbeam of beam body lateral arrangement, be provided with the maximum displacement position limiting structure between side bar and the central sill and between adjacent two central sills.
As optimized technical scheme, described maximum displacement position limiting structure adopts flexible stainless steel wire rope to make.
Further be, be set with supported box on side bar, be fixedly connected with supporting frame below each central sill, the crossbeam movable set is in supported box and supporting frame; The maximum displacement position limiting structure is connected between supported box and supporting frame and adjacent two supporting frames.
The beneficial effects of the utility model are: owing to be provided with the maximum displacement position limiting structure between side bar and the central sill and between adjacent two central sills, flexible gap width between side bar and the central sill, between adjacent two central sills can be limited in the control range of maximum displacement position limiting structure, thereby prevent that indivedual slits that stretching device may occur are wide and cause the increase of vehicle in long-term use the shock loading of shaped steel.Though the displacement control system of stretching device has guaranteed the displacement uniformity of stretching device basically, but the utility model is provided with the great endurance quality that improves stretching device on common big displacement quantity stretching device, is particluarly suitable for promoting the use of above the bridge shaped steel expansion gap device of big displacement.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional view of A-A direction among Fig. 1.
Be labeled as among the figure: side bar 1, central sill 2, crossbeam 3, maximum displacement position limiting structure 4, supported box 5, supporting frame 6.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1 and Figure 2, bridge shaped steel of the present utility model shrinkage joint position limiting structure, comprise side bar 1 and the central sill between both sides side bar 12 in beam body both sides, side bar 1 is vertically arranged along the beam body with central sill 2, below side bar 1 and central sill 2, be provided with, it is characterized in that: be provided with maximum displacement position limiting structure 4 between side bar 1 and the central sill 2 and between adjacent two central sills 2 along the crossbeam 3 of beam body lateral arrangement.When bridge is flexible, flexible gap width between side bar 1 and the central sill 2, between adjacent two central sills 2 can be along with variation, and this maximum displacement position limiting structure 4 by being provided with, flexible gap width between side bar 1 and the central sill 2, between adjacent two central sills 2 can be limited in the control range of maximum displacement position limiting structure 4, thereby prevent that indivedual slits that stretching device may occur are wide and cause the increase of vehicle in long-term use the shock loading of shaped steel.This maximum displacement position limiting structure 4 can adopt mechanisms such as telescopic sleeve, slide block to realize, the maximum elongation amount of promptly controlling sleeve, slide block is to realize control maximal dilation seam width.As optimal way, described maximum displacement position limiting structure 4 adopts flexible stainless steel wire rope to make.It is simple in structure to adopt flexible wire ropes can make as maximum displacement position limiting structure 4, and in addition, flexible wire ropes also has certain damping action, the moment impact that brings in can the slowly-releasing telescopic process.
For forming support protective effect to crossbeam 3, on side bar 1, be set with supported box 5, below each central sill 2, be fixedly connected with supporting frame 6, crossbeam 3 movable sets are in supported box 5 and supporting frame 6; Maximum displacement position limiting structure 4 is connected between supported box 5 and supporting frame 6 and adjacent two supporting frames 6.Then bridge makes crossbeam 3 in supported box 5 and supporting frame 6 slippages in telescopic process.
