The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.As shown in Figure 1, device of the present invention be a kind of on bridge expanssion joint, be provided with can be with the flexible linkage of bridge floor beam body.Be embedded with embedded bar 2 and 5 in the bridge floor of both sides, shrinkage joint or beam body 6, this is same as the prior art.The supporting steel plate 9 at the supporting steel plate 11 of whole device and two ends equably in the present invention, and vertically be arranged on the both sides at shrinkage joint, between per two supporting steel plates 9,11, be provided with the spring leaf 10 (number of spring leaf 10 is decided as required) of fixedlying connected with adjacent supports steel plate 9,11.On supporting steel plate 9,11, be provided with and the contour upper steel plate 8 of deck paving horizontal plane, be provided with at the end face of a plurality of spring leafs 10 and support backing plate 13.At supporting steel plate 9,11 with support backing plate 13, and be filled with waterproof seal 12 in the space that surrounded of upper steel plate 8.The supporting steel plate 9 at two ends and employing double welding 7 such as embedded bar 2, anchor plate 4 are connected to one in this device.Whole device, except the supporting steel plate 9 at two ends with pontic is fixedlyed connected, the other parts of this device (except that waterproof seal 12) are mutually permanently connected and are integral body, in fact whole device is suspended on the shrinkage joint, therefore, good integrity, it can be flexible simultaneously with pontic.After this device connected, the concrete of mating formation of again that the sub-concrete of C50 microlith 3 is cast-in-place and flattening device both sides certain width can be open to traffic after cast-in-situ concrete is solidified.This figure illustrated embodiment is the device that is used for D160 and following less beam-ends shrinkage joint.
Be vertical view as shown in Figure 3, on this figure in order to show upper steel plate 8, with real thin demonstration on right-hand the 2nd supporting steel plate of figure is exactly upper steel plate 8, shown in the dotted line on supporting steel plate 9 both sides on its right also is upper steel plate, spring leaf 10 is arranged on two supporting steel plates 9 as can be seen from the figure, between 11, spring leaf 10 is at least 3, also can be for a plurality of, when a plurality of spring leafs at two supporting steel plates 9, when forming the arrangement of a spring leaf 10 between 11, its end face level height is consistent, described support backing plate 13 just is arranged on a plurality of spring leafs 10, and with spring leaf 10 for not fixedlying connected, be support backing plate 13 at two dotted lines in the illustrated left side, described waterproof seal 12 just is arranged on this and supports on the backing plate 13, to support between backing plate 13 and the upper steel plate 8 and two supporting steel plates 9, fill in space between 11, plays the effect of waterproof and sealing.
Accompanying drawing 4 is depicted as the vertical view of another embodiment, and in the diagram, the dotted line of supporting steel plate 9,11 both sides on both sides is depicted as upper steel plate 8, and the big dotted line of central authorities is represented beam-ends edge 18, just the edge at shrinkage joint.Described stride the seam steel plate 14 be shown in the little dotted line, this embodiment is the device that is used for the above big beam-ends shrinkage joint of D160, combine with accompanying drawing 2 and to see, it is more much bigger than upper steel plate 8 that this strides seam steel plate 14, directly cover on the shrinkage joint, main effect is to stride seam to support, and bears vehicular load, simultaneously tie-beam seam both sides extensible member.
In a word, the major function of apparatus of the present invention is to make bridge beam body capable of expansion and contraction, makes driving comfortable simultaneously, prevents that rainwater from flowing into the beam seam.The groundwork principle is: the operating principle of anchor connector is very intuitively, plays the anchor connection effect in the use.The operating principle of steel bomb reed is, when beam seam telescopic variation, and steel bomb reed generation elasticity displacement and satisfy flexible requirement; The wheel pressure that steel frame is afforded passes to the beam body simultaneously.Steel frame then bears wheel pressure at any time, and provides working space for spring leaf and waterproof seal.
