Abstract
The utility model belongs to the technical field of expansion joint, which discloses an expansion device support, displacement controlling box, characterized in that: comprising a displacement box arranged on the two ends of the cross beam, a support is arranged between the bottom of the cross beam and the displacement box, the top surface of two ends of the cross beam is provided with a groove, the top part of the displacement box, where is matched with the groove on the top surface of the cross beam, is provided with a fixing hole, shearing springs are fixedly arranged between the top surface of the cross beam and the displacement box. The expansion device support, displacement controlling box is provided with the shearing springs, when the edge beam on the cross beam is shifted by the heat-expansion and cold-contraction, the several shearing springs arranged in the longitudinal direction of the cross beam are shifted synchronously, taking guarantee the whole movement of the edge beam. The shearing springs are substitutes for the upper support and the control device of the original expansion device, so the parts are reduced, the size of the displacement box is smaller, and the installation is simple.
Description
Technical field
The utility model belongs to the shrinkage joint technical field, relates in particular to a kind of stretching device support, displacement control casing.
Background technology
Presently used bridge expanssion joint is at the two ends of bridge crossbeam the displacement case to be set, and between crossbeam end face, bottom surface and displacement case upper and lower bearing is set respectively.The bridge expanssion joint of this structure, the upper bracket of its crossbeam end face is only played a supporting role, when the side bar on the crossbeam produces displacement because of expanding with heat and contract with cold, several upper brackets that vertically are provided with along crossbeam need to move simultaneously to guarantee the whole displacement of side bar, therefore also are provided with control device in the displacement case so that several upper brackets move simultaneously.Like this, make that just whole stretching device parts are more, displacement box body size is bigger, and trouble is installed, and the link that goes wrong is more.
The utility model content
It is few that problem to be solved in the utility model just provides a kind of parts, and displacement box body size is little, and simple stretching device support, displacement control casing are installed.
For addressing the above problem, the technical solution adopted in the utility model is: comprise the displacement case that is arranged on the crossbeam two ends, be provided with bearing between crossbeam bottom surface and displacement case, the end face at described crossbeam two ends has groove, the top of displacement case and crossbeam end face groove matching part have fixing hole, are fixed with shear spring between crossbeam end face and displacement case.
Its additional technical feature is: described shear spring is the block rubber that has the upper and lower steel plate that is connected as a single entity with it, upper and lower steel plate has the upper and lower fixed block that is connected as a single entity with it respectively, last fixed block snaps in the fixing hole of displacement box top, and following fixed block snaps in the groove of crossbeam end face.
Stretching device provided by the utility model supports, displacement control casing, be provided with the shear spring that the block rubber that has the upper and lower steel plate that is connected as a single entity with it constitutes between the end face at crossbeam two ends and displacement case, shear spring fixes by the groove of upper and lower fixed block on the upper and lower steel plate and crossbeam, the fixing hole of displacement case.When the side bar on the crossbeam produced displacement because of expanding with heat and contract with cold, the block rubber of several shear springs that vertically are provided with along crossbeam produced displacement simultaneously under last fixed block and upper steel plate effect, whole mobile to guarantee side bar.This shear spring has substituted the effect of upper bracket and control device in the original stretching device, makes parts reduce, and displacement box body size reduces, and installs simple.
Description of drawings
Accompanying drawing is for the utility model stretching device supports, the structural representation of displacement control casing.
The specific embodiment
Below in conjunction with accompanying drawing structure and the use principle that the utility model stretching device supports, casing is controlled in displacement is described in further details.
As shown in the figure, the utility model stretching device supports, displacement control casing comprises the displacement case 2 that is arranged on crossbeam 1 two ends, 2 in crossbeam 1 bottom surface and displacement case are provided with bearing 3, be provided with central sill 4 above the crossbeam 1, side bar 5 and weather strip 6, the end face at crossbeam 1 two ends has groove 7, the top of displacement case 2 has fixing hole 8, between the end face at crossbeam 1 two ends and displacement case 2, be provided with shear spring 9, shear spring 9 is by having the upper steel plate 10 that is connected as a single entity with it, the block rubber 12 of lower steel plate 11 constitutes, upper steel plate 10, have the last fixed block 13 that is connected as a single entity with it on the lower steel plate 11 respectively, following fixed block 14, last fixed block 13 snaps in the fixing hole 8 at displacement case 2 tops, and following fixed block 14 snaps in the groove 7 of crossbeam 1 two ends end face.
During use, stretching device is placed on basic reservation place, cast is good then gets final product.When the side bar on the crossbeam 15 produced displacement because of expanding with heat and contract with cold, the block rubber 12 of several shear springs 9 that vertically are provided with along crossbeam 1 produced displacement simultaneously under last fixed block 13 and upper steel plate 10 effects, whole mobile to guarantee side bar 5.
Claims (2)
1. stretching device support, displacement control casing, comprise the displacement case that is arranged on the crossbeam two ends, be provided with bearing between crossbeam bottom surface and displacement case, it is characterized in that: the end face at described crossbeam two ends has groove, the top of displacement case and crossbeam end face groove matching part have fixing hole, are fixed with shear spring between crossbeam end face and displacement case.
2. stretching device according to claim 1 supports, displacement control casing, it is characterized in that: described shear spring is the block rubber that has the upper and lower steel plate that is connected as a single entity with it, upper and lower steel plate has the upper and lower fixed block that is connected as a single entity with it respectively, last fixed block snaps in the fixing hole of displacement box top, and following fixed block snaps in the groove of crossbeam end face.
