Abstract
The utility model discloses a criss-crossing type extending and contracting device which comprises a plurality of edge beam structural steel arranged in the longitudinal direction and the transverse direction and an anchoring rib plate for fixing the edge beam structural steel. Extending and contracting seams arranged on the interval portions of the edge beam structural steel, rubber sealing strips for connecting every two edge beam structural steel are arranged on the extending and contracting seam portions, and crossing extending and contracting seams are arranged on the crossing portion in the longitudinal direction and the transverse direction. The criss-crossing type extending and contracting device is characterized in that the rubber sealing strips are integral crossing rubber sealing strips formed in a compression molding mode. The structural steel is integrated with the anchoring rib plate of a bridge structure, the adopted integral crossing rubber sealing strips formed in the compression molding mode is in total sealing connection with the structural steel in the crossing portion by considering the angle of the crossing extending and contracting seams, and the watertightness of the extending and contracting device is ensured.
Description
Technical field
The utility model relates to a kind of stretching device, particularly relates to a kind of cruciform shape stretching device, belongs to building fields such as highway and railroad bridge.
Background technology
Staggered form stretching device in the market is made up of side bar shaped steel and rubber seal tape, and side bar shaped steel is mainly selected the special-purpose shaped steel of stretching devices such as C, F, Z type for use; Rubber weather strip is mainly selected according to stroke 60mm, 80mm, is applied in abutment or the bridge position of bridge widening usually; The embedded bar of cross section shaped steel and bridge construction connects into integral body, handles and the rubber seal strip adoption is glued, leaks with the effect of natural conditions fracture for a long time, and the bearing that can influence bridge substructure uses, even influences the bridge beam body structure.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is, a kind of cruciform shape stretching device is provided, adopt the monolithic devices intersection rubber weather strip of compression molding, in conjunction with intersecting the angle at shrinkage joint, be tightly connected fully with the shaped steel of infall, guarantee the dense water of stretching device.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the cruciform shape stretching device, comprise vertical and horizontal several side bar shaped steel and the fixing anchoring gusset of side bar shaped steel, described side bar shaped steel interval is provided with the shrinkage joint, the place is provided with the rubber weather strip that connects two side bar shaped steel at described shrinkage joint, be provided with the intersection shrinkage joint at vertical and horizontal infall, it is characterized in that: described rubber weather strip is the monolithic devices intersection rubber weather strip of compression molding.
Aforesaid cruciform shape stretching device is characterized in that: described side bar shaped steel is " Z " type, " C " type, " E " type or " F " type side bar shaped steel.
Aforesaid cruciform shape stretching device is characterized in that: the maximal dilation amount of described rubber weather strip is 80mm.
Aforesaid cruciform shape stretching device is characterized in that: described intersection shrinkage joint is 80 mm along crisscross maximal dilation amount.
The beneficial effects of the utility model are:
1. can the intersection stretching device rationally be set connect bridge one-tenth integral body according to the flexible requirement of bridge beam body;
2. the anchoring gusset of shaped steel and bridge construction connects into integral body, adopts the monolithic devices of compression molding to intersect rubber weather strip, in conjunction with the angle at intersection shrinkage joint, is tightly connected fully with the shaped steel of infall, guarantees the dense water of stretching device.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 vertical view of the present utility model.
The specific embodiment
For further disclosing the technical solution of the utility model, describe embodiment of the present utility model in detail below in conjunction with accompanying drawing: as depicted in figs. 1 and 2, the cruciform shape stretching device, comprise " Z " type side bar shaped steel 1, " F " type side bar shaped steel 2 and the fixing anchoring gusset 3 of side bar shaped steel, vertical and horizontal " Z " type side bar shaped steel 1 and " F " type side bar shaped steel 2 are provided with intersection shrinkage joint 4 at infall, and intersection shrinkage joint 4 is 80 mm along crisscross maximal dilation amount.
Intersection 4 places, shrinkage joint are provided with the monolithic devices intersection rubber weather strip 5 of the compression molding that connects two side bar shaped steel, and the maximal dilation amount of rubber weather strip 5 is 80mm.Adopt the monolithic devices of compression molding to intersect rubber weather strip 5, in conjunction with the angle at intersection shrinkage joint 4, be tightly connected fully with the shaped steel of infall, guarantee the dense water of stretching device.
More than by description of listed embodiment, basic design of the present utility model and basic principle have been set forth.But the utility model never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on the technical solution of the utility model of change all should belong to protection domain of the present utility model.
