Description
Technical field
The utility model belongs to stretching device technical field, relates in particular to a kind of longitudinal extension device that the constuction joint of two bridges can be linked together that is used in.
Background technology
Stretching device be arranged between two beam bodies that form bridge, between beam body and abutment for solving the linkage because of gap between horizontal direction is expanded with heat and contract with cold or other reasons causes beam body or beam body and abutment.And along with the development of transportation industry, its road surface, bridge are constantly widened on original basis; To the road surface being paved by the cubic metre of earth and stone, its widened section can be added on maintenance according to the amplitude of its sinking; But for the bridge of widening, be difficult to by repairing to eliminate because the sedimentation after construction or construction causes two beam bodies formed construction settlement joint that misplaces up and down.And this up and down settlement joint that dislocation forms can make motor vehicle be difficult to cross over or leap can cause certain jolting, vibrate, and long-term jolting not only can cause motor-driven vehicle going to be affected, to the more important thing is the damage that can cause bridge beam body.
Utility model content
The purpose of this utility model is just to provide and a kind ofly can connects longitudinal extension device between two beam bodies, that can realize longitudinal strain.
Realizing the technical scheme that the utility model above-mentioned purpose adopts is:
A longitudinal extension device, comprises
What can longitudinally be individually fixed in the weather-resistant steel plate of beam side portion and be fixed on corresponding beam side portion some arranges reeded fixedly matrix;
On described weather-resistant steel plate and described fixedly matrix, along the longitudinal lap joint of beam body, have across shrouding;
Described across weather-resistant steel plate side corresponding to shrouding two bottom sides and fixedly matrix side be respectively arranged with permanent magnet and fixed bias circuit, described permanent magnet can produce magnetic attraction with weather-resistant steel plate, and described fixed bias circuit snaps in the groove of described fixedly matrix;
Described fixedly matrix corresponding across shrouding place, be provided with window, at this window place, be provided with the hinge plate that sidepiece can be fixing with corresponding beam body, this hinge plate is connected with described fixed bias circuit axle.
In addition, the additional technical feature that forms above-mentioned longitudinal extension device comprises:
---at described hinge plate and described fixed base interblock, be provided with and be connected base;
---described hinge plate and described fixed base interblock are fixed by connecting bolt;
---described stretching device across shrouding and the fixed bias circuit that is fixed together with it, be subsection setup.
A kind of longitudinal extension device provided by the utility model, have the following advantages: one, between the longitudinal slot moving towards along bridge due to two beam bodies formations before and after widening, be overlapped with a side by magnet piece with the fixing weather-resistant steel plate of beam body produce magnetic attraction across shrouding, and should be overlapped on corresponding Bridge Beam side across the opposite side of shrouding, and pass through the connected Hinge mechanism being formed with fixed bias circuit by hinge plate and be connected, thereby realize lapping plate to widening being connected longitudinally of beam body of bridge and widened bridge, can be so that motor vehicle passes through between two beam bodies, can't produce vibration, its two, because longitudinal extension device is in the process of two beam bodies relative motion, can remain contacting of face and face, there is not stress concentration phenomenon, whole stretching device can link together all the time closely, makes to realize seamless link between two beam bodies, its three, because the critical piece of stretching device is steel part, without aging phenomenon exist, long service life, and this stretching device is segment design, changes easy to maintenance.
Accompanying drawing explanation
The structural representation of the longitudinal extension device that Fig. 1 provides for the utility model;
Fig. 2 is above-mentioned longitudinal extension device A-A bridge deck structure schematic diagram;
Fig. 3 is for being above-mentioned longitudinal extension device B-B bridge deck structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the structure of longitudinal extension device provided by the utility model is described in further detail.
The structural representation of the longitudinal extension device providing for the utility model as shown in Figure 1,2 and 3.The structure that forms this device comprise respectively (arrow) C-C longitudinally by embedded bar 14 be fixed on weather-resistant steel plate 11 on beam body 5 sidepieces and longitudinally (arrow) C-C be fixed on corresponding to several of another curb girder body 6 sidepieces and be provided with the fixedly matrix 7 of groove 8, at above-mentioned weather-resistant steel plate and 9 of longitudinal slots fixedly producing along two beam bodies on matrix, be overlapped with longitudinally across shrouding 1; This across weather-resistant steel plate side corresponding to the both sides of shrouding bottom and fixedly matrix side be respectively arranged with permanent magnet 13 and fixed bias circuit 15, this permanent magnet can produce magnetic attraction with weather-resistant steel plate, and fixed bias circuit is matched in the groove 8 of fixing matrix and can relatively rotates; Above-mentioned fixedly matrix corresponding across shrouding place, be provided with window 12, at this window place, being provided with sidepiece can be with corresponding beam body 6 by service sleeve and the fixing hinge plate 2 of bolt 16,15 of this hinge plate 2 and fixed bias circuits are rotationally connected.
The operating principle that forms above-mentioned longitudinal extension device is: transverse joint plate 1 and fixed bias circuit 5 are fixed together, and with the hinge plate 2 being fixed as one with beam body and reeded fixedly matrix 7 is set forms revolute pairs, and fixed bias circuit 15 is stuck in relative rotation in groove, no matter the widened section of bridge beam body is to sink or projection, it is connected in all can rotate around fixed bias circuit 15 across shrouding between two beam bodies, make movable turning cylinder and fixedly matrix vertical force is reasonably delivered to beam body.Moving up and down by fixed bias circuit 15 of beam body realizes moving horizontally by fixedly moving horizontally realization between matrix and weather-resistant steel plate between two beam bodies, across the permanent-magnet block arranging under shrouding, can prevent the bob of transverse joint plate.
