However, the traditional shear hinge is a solid bar (as shown in fig. 1), is positioned in the middle of the floating plate or floats on the surface of the floating plate, has small sectional area, needs to be provided with 4 groups, and still can not resist bending moment and shearing force well. In the actual use process, the steel rail at the plate seam still has the conditions of larger stress and larger deformation, and the plate end fastener also bears great stress and is easy to damage, thereby influencing the service life of the plate end fastener. In order to improve the stress condition of the steel rail and the fastener, the floating slab end adopts a method of encrypting the slab end vibration isolator to increase the rigidity of the slab end, thereby increasing the manufacturing cost.

As shown in the figure, the shear hinge 3 includes a shear unit 31 connected with the first floating plate 1 and a limiting unit 32 embedded in the second floating plate 2, where the shear unit 31 adopts a steel structure with a U-shaped cross section. The limiting unit 32 adopts a cylindrical structure matched with the shearing unit 31, so that the shearing unit 31 can be inserted into the cylindrical structure.
When the shear device is used, the shear unit 31 connected with the first floating plate 1 is inserted into the limiting unit 32 positioned in the second floating plate 2, wherein a plate seam of about 30mm is reserved between the first floating plate 1 and the second floating plate 2, concrete 7 is poured into the U-shaped steel structure through the opening of the U-shaped steel structure of the part of the shear unit 31 positioned between the first floating plate 1 and the second floating plate 2, and the advantage of combination of the concrete 7 and the U-shaped steel structure is utilized to form a square steel tubular beam structure. The U-shaped steel structure of the shearing resistant unit 31 is combined with the concrete 7, so that the sectional area of the U-shaped steel structure is far larger than that of the traditional shear hinge 3, and the shearing resistance of the single shear hinge 3 is greatly improved, and the shearing resistance of the single shear hinge 3 is higher than that of the traditional shear hinge 3 of 4 groups, so that each slab joint can meet the shearing resistant requirement only by arranging 2 groups of shear hinges 3. And the U-shaped steel structure of the shear hinge 3 is combined with the concrete 7, so that the moment of inertia of the cross section is larger, and the shear hinge has good bending resistance. In addition, as the shear hinge 3 is arranged right below the steel rail, the stress of the steel rail and the stress of the plate end fastener are reduced, thereby avoiding the problem of using an encrypted vibration isolator to increase the rigidity of the plate end and greatly reducing the cost.
Preferably, the shear hinge 3 further comprises a first longitudinal bar fixing ring 33 connected with the shear unit 31, wherein the longitudinal bars 4 of the first floating slab 1 are inserted into the first longitudinal bar fixing ring 33 so as to fix the shear unit 31 on the longitudinal bars 4 of the floating slab, thereby omitting a binding step and greatly enhancing the concrete binding force with the first floating slab 1. Likewise, the shear hinge 3 preferably further comprises a second longitudinal bar fixing ring 34 connected with the limiting unit 32, and the longitudinal bars 4 of the second floating slab 2 are inserted into the second longitudinal bar fixing ring 34 so as to fix the limiting unit 32 on the longitudinal bars 4 of the floating slab, thereby omitting the binding step and greatly enhancing the concrete binding force with the second floating slab 2. During manufacturing, when the first floating plate 1 and the second floating plate 2 are poured, the longitudinal steel bars 4 of the first floating plate 1 are inserted into the first longitudinal bar fixing rings 33, the longitudinal steel bars 4 of the second floating plate 2 are inserted into the second longitudinal bar fixing rings 34, and concrete 7 in the U-shaped steel structure is poured simultaneously when the first floating plate 1 and the second floating plate 2 are poured, so that the first floating plate 1 and the second floating plate 2 are tightly combined with the shear hinge 3 to form a whole, and the shearing resistance is further improved.
It should be noted that, although the cross section of the shear unit 31 is shown as a U-shape in this embodiment, it should be noted that, in other embodiments of the present invention, the cross section of the shear unit 31 may be other closed or non-closed ring-shaped steel structures. Here, the closed or non-closed ring-shaped steel structure includes a circular ring, an elliptical ring, a rectangular ring, a hexagonal ring, etc., and the circular ring (as shown in fig. 8, the stopper unit 32 fitted thereto is shown in fig. 9), the elliptical ring, the rectangular ring, the hexagonal ring, etc., may be closed or non-closed (i.e., have an opening), and when the ring-shaped steel structure is closed, a portion of the shear unit 31 between the first floating plate 1 and the second floating plate 2 is provided with a concrete pouring port 35 so that the concrete 7 is poured into the inside of the ring-shaped steel structure through the concrete pouring port 35. When the ring-shaped steel structure is not closed, then the opening of the ring-shaped steel structure is used as a concrete pouring opening 35 to pour concrete 7 into the inside of the ring-shaped steel structure through the concrete pouring opening 35.
Further, when the cross section of the ring-shaped steel structure is U-shaped, a reinforcing plate 36 (shown in fig. 7) parallel to the side walls of the U-shaped structure is preferably provided at the center of the bottom of the ring-shaped steel structure in order to further improve the shear and bending resistance of the shear hinge 3. And preferably a reinforcement cage is also provided inside the annular steel structure.
In addition, the first longitudinal bar fixing ring 33 and the second longitudinal bar fixing ring 34 are elongated holes, at least two longitudinal bars 4 of the first floating plate 1 are inserted into the same first longitudinal bar fixing ring 33, and at least two longitudinal bars 4 of the second floating plate 2 are inserted into the same second longitudinal bar fixing ring 34. According to the shear hinge 3 provided by the invention, the first longitudinal bar fixing rings 33 are arranged into the long holes, so that at least two longitudinal bars 4 of the first floating plate 1 are inserted into the same first longitudinal bar fixing ring 33, and therefore, when the space between the longitudinal bars 4 on the first floating plate 1 has errors, the shear hinge can still be inserted into the same first longitudinal bar fixing ring 33, and the working efficiency is improved. Likewise, the second longitudinal bar fixing rings 34 are provided with elongated holes, so that at least two longitudinal bars 4 of the second floating plate 2 are inserted into the same second longitudinal bar fixing ring 34, and therefore, when an error exists in the space between the longitudinal bars 4 on the second floating plate 2, the second floating plate can still be inserted into the same second longitudinal bar fixing ring 34, and the working efficiency is improved.
In this embodiment, the number of the first longitudinal rib fixing rings 33 is two, and the two first longitudinal rib fixing rings 33 are spaced apart along the length direction of the shear unit 31, so that the longitudinal reinforcing bars 4 of the first floating plate 1 sequentially pass through the two first longitudinal rib fixing rings 33, thereby improving the connection reliability of the first floating plate 1 and the shear unit 31. It should be noted that, although two first longitudinal rib fixing rings 33 are shown in this embodiment, it should be understood by those skilled in the art that in other embodiments of the present invention, the number of first longitudinal rib fixing rings 33 may be more than two, for example, three, four, etc., and the longitudinal bars 4 of the first floating plate 1 sequentially pass through the plurality of first longitudinal rib fixing rings 33.
Similarly, in this embodiment, the number of the second longitudinal bar fixing rings 34 is two, and the two second longitudinal bar fixing rings 34 are spaced apart along the length direction of the spacing unit 32, so that the longitudinal bars 4 of the second floating plate 2 sequentially pass through the two second longitudinal bar fixing rings 34, thereby improving the connection reliability of the second floating plate 2 and the spacing unit 32. It should be noted that, although two second longitudinal bar fixing rings 34 are shown in this embodiment, it should be understood by those skilled in the art that in other embodiments of the present invention, the number of second longitudinal bar fixing rings 34 may be more than two, for example, three, four, etc., and the longitudinal bars 4 of the second floating plate 2 sequentially pass through the plurality of second longitudinal bar fixing rings 34.
In addition, in other embodiments of the present invention, a plurality of first longitudinal bar fixing rings 33 arranged along the width direction of the shear unit 31 may be disposed on the shear unit 31, and the plurality of longitudinal bars 4 of the first floating plate 1 are uniformly and correspondingly inserted into one or a row of first longitudinal bar fixing rings 33 arranged along the length direction. Similarly, a plurality of second longitudinal bar fixing rings 34 arranged along the width direction of the limiting unit 32 may be disposed on the limiting unit 32, and the plurality of longitudinal bars 4 of the second floating plate 2 are inserted into one or a row of second longitudinal bar fixing rings 34 arranged along the length direction in a one-to-one correspondence manner.
Further, one end of the cylindrical structure far away from the shear unit 31 is closed, and an elastic filling layer 5 is arranged at one end of the cylindrical structure far away from the shear unit 31, and the elastic filling layer 5 can be made of high polymer materials such as rubber polyurethane, so that the elastic filling layer has elasticity, a telescopic space can be provided, and deformation and telescopic action of the floating plate caused by temperature cannot be influenced.
Further, the exhaust hole 6 is further formed in the cylinder wall of the cylindrical structure and used for exhausting and draining air when the concrete 7 in the floating slab and the shear hinge 3 is poured, so that the gas in the limiting unit 32 is prevented from being condensed, the pouring of the concrete 7 is influenced, the pouring compactness of the concrete 7 is ensured, and the formation of a cavity is prevented.
In addition, the lubricating layer is coated on the inner wall of the limiting unit 32 and used for isolating the concrete 7, preventing the concrete 7 from being adhered to the inner wall of the limiting unit 32, and ensuring that the shearing-resistant unit 31 can longitudinally slide in the limiting unit 32, so that deformation and expansion and contraction of the floating plate caused by temperature are not influenced.
Further, since the shear unit 31 is exposed to the air at the seam between the first floating plate 1 and the second floating plate 2 after the installation of the shear hinge 3 is completed, it is preferable to coat an anti-corrosive material (e.g., hot dip galvanizing, etc.) on the portion of the shear unit 31 between the first floating plate 1 and the second floating plate 2 to prevent the shear unit 31 from rusting, extending the service life thereof.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
