Abstract
The utility model discloses a shearing force mortise-tenon, which is characterized in that the shearing force mortise-tenon comprises an upper plate and a lower plate, wherein corresponding surfaces are formed on a relative end of the upper plate and the lower plate, one of the corresponding surfaces is equipped with a slider, the other one corresponding surface is equipped with a chute, the slider is located in the chute, and a gap is arranged between the top portion of the slider and the bottom portion of the chute. The shearing force mortise-tenon is matched with a rubber supporting seat to be fixedly arranged between a bridge beam and a bridge pier, the direction of the slider follows the bridge direction, when the upper plate and the lower plate bear the horizontal shear of the bridge direction, the slider can slide in the chute, when the upper plate and the lower plate bear the horizontal shear of the transverse direction, the slider and the chute are matched to play the role of locating and bearing the horizontal shear.
Description
Technical field
The utility model relates to a kind of bridge construction architectural detail, plays the shearing trip of the horizontal force between bridge and the bridge pier of preventing in particularly a kind of bridge construction.
Background technology
General elevated road, railway or bridge mostly are to support bridge by many bridge piers to form, and in order to strengthen the safety of bridge, the shearing trip of the damping device and the horizontal force of preventing are installed between bridge and bridge pier usually.Existing shearing trip normally utilizes the rod iron that is fixed between bridge and the bridge pier horizontal force of preventing, known rod iron is embedded between bridge and the bridge pier, precision that it is installed and gap are difficult for grasping, and be not suitable for the Structural Engineering of modernized High Speed System, and lifting surface area is little and inhomogeneous, causes the difficulty on the design and construction easily.
Summary of the invention
The purpose of this utility model is: provide a kind of convenient construction, the shearing trip of the horizontal force between bridge and the bridge pier of can effectively preventing.
The technical solution of the utility model is:
A kind of shearing trip is characterized in that: this shearing trip comprises upper plate and lower plate, forms corresponding surface at upper plate and lower plate opposite end, wherein a corresponding surface is provided with slide block, another corresponding surface is provided with chute, and slide block is arranged in chute, between the top of slide block and the chute bottom gap is arranged.
Supplementary technology scheme of the present utility model is as follows:
Preferably, described gap is 10～30mm.
Preferably, slide block is arranged on the upper plate bottom, and corresponding chute is arranged on the lower plate top.
Preferably, the cross section of slide block is a rectangle.
Preferably, also have a dismountable fixed head to be installed on upper plate and the lower plate.
Preferably, be fixed with the anchorage rod iron, be fixed with grappling rod iron down in the lower plate bottom at the upper plate top.
Preferably, be provided with the tension annulus at last anchorage rod iron and following anchorage rod iron top.
The beneficial effects of the utility model are: the utility model is and neoprene bearing is used and is fixedly mounted between bridge and the bridge pier, wherein the slide block direction be along bridge to, when upper plate and lower plate bear along bridge to horizontal shear the time, slide block just slides in the chute, when upper plate and lower plate are born horizontal horizontal shear, hold to cooperate by slide block and chute and play the location and bear the horizontal shear effect.
Description of drawings
Fig. 1 is that the axle of the utility model shearing trip is surveyed view.
Fig. 2 is the elevation of shearing trip shown in Figure 1.
Fig. 3 is the vertical view of shearing trip shown in Figure 1.
Wherein, Reference numeral: 1 is upper plate, and 2 is lower plate, and 3 is slide block, and 4 is chute, and 5 is last anchorage rod iron, and 6 are following grappling rod iron, and 7 is the tension annulus.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model, as shown in Figure 1, a kind of shearing trip that is used to bear horizontal shear between bridge and the bridge pier that is installed in, this shearing trip and neoprene bearing are used, and neoprene bearing bears vertical power, and the shearing trip bears horizontal force.This shearing trip comprises upper plate 1 and lower plate 2, form corresponding surface at upper plate 1 and lower plate 2 opposite ends, on upper plate 1 bottom corresponding surface, be provided with the slide block 3 that a cross section is a rectangle, on the corresponding surface of lower plate top, be provided with chute 4, slide block 3 is arranged in chute 4, the two also can oppositely be provided with, and between the top of slide block 3 and chute 4 bottoms gap is arranged, and the scope in gap is good with 10～30mm.For the ease of upper plate 1 and lower plate 2 are separately fixed on bridge and the bridge pier, and maintenance certain intensity, the upper plate top is fixing also have on anchorage rod iron 5, fixing in the lower plate bottom also have grappling rod iron 6 down, is provided with tension annulus 7 at last anchorage rod iron 5 with following anchorage rod iron 6 tops.
Owing in installation process, need to keep the distance between upper plate 1 and the lower plate 2, be convenient to the location, can also be on upper plate 1 and lower plate 2 dismountable a fixed head be installed, be used to keep the distance between the two, to guarantee the gap between slide block 3 and the chute 4.
