Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for a groove cover which is bridged between structures, for example, at least one of frames forming a seismic isolation structure.

[0002]

2. Description of the Related Art Generally, gaps are provided at appropriate intervals around a frame of a seismic isolation structure in consideration of vibrations caused by an earthquake, and a groove cover is usually provided at a place where vehicles and pedestrians pass. FIG. 1 shows an example of a conventional method, in which a groove cover 2 to which a ramp 1 having inclined surfaces on both sides is fixed is bridged between a frame A and a frame B having a seismic isolation structure.

[0003] In such a groove cover, the vehicle is pushed and moved by the traffic of the vehicle, and tends to fall off the groove edge and fall off. Similar to the normal mounting structure of the groove cover, the groove cover is attached to the recess formed at the groove edge or the receiving metal fitting attached to the recess, or the protrusion or the protrusion protruding downward from the groove cover is formed in the groove. If fitted, the groove lid described above can be prevented from falling off, but it cannot respond to shaking such as an earthquake, and may fall off, deform, or jump out of the groove and hinder vehicle traffic. is there.

Japanese Patent Application Laid-Open No. 1-125476 discloses that one end of an erecting member 5 is tilted up and down by a hinge 6 on one of a seismic isolation structure 3 and a surrounding ground 4 as shown in FIG. And the other end of the erection member 5 is connected to the structure 3
Alternatively, a structure that is movably laid over the ground 4 is disclosed. In the figure, reference numerals 7 and 8 denote finishing members having the same thickness as the erection member 5 and finished on the structure 3 and the ground 4, and 9 denotes a flexible gasket which can be elastically deformed.

[0005]

FIG. 2 shows a supporting structure of a groove cover.
With the structure shown in the above, the gutter can be supported without falling off due to the shaking of an earthquake or the like, deforming or jumping out of the groove.
As shown in FIG. 3, when the gap C narrows significantly, the end of the groove cover may protrude beyond the gasket, and when the vehicle passes, the end of the groove cover may hinder the passage. Eliminating the finishing member and gasket to solve this problem creates a step at the end of the groove lid, which causes an impact when the vehicle passes, which may damage the hinge or cause a pedestrian to pass. May cause tripping.

[0006] It is an object of the present invention to provide a groove lid support structure that can solve the above-mentioned problems.

[0007]

According to the present invention, one end of a groove cover is connected to one of the structures having an appropriate distance, and preferably one of the structures is connected by a hinge so as to be tiltable up and down. The support structure of the groove lid having the other end movably supported, wherein the support surface of the structure that movably supports the groove lid end is an inclined surface that descends forward toward the opposing structure. I do.

According to the present invention, the groove end face and the inclined surface that ride on the inclined surface form an acute groove. Since the thickness of the gutter is usually less than 10 cm and not thick, it is less likely to cause a shock when a vehicle passes or a stumbling block when a pedestrian walks, but enables smoother traveling and traffic. It is preferable to provide a ramp which is hung on an inclined surface at the end of the groove, and it is more preferable that the ramp is connected to the groove lid by the above-mentioned hinge means so that the groove can be raised.

By providing a ramp extending over the groove, a step with the end face of the groove lid is eliminated, and by allowing the ramp to be raised, the ramp end is supported in close contact with the inclined surface. In the groove lid of the present invention, in order to smoothly move on the structure, a rod having a contact surface with the structure in an arc shape is fixed to the other end of the groove lid movably supported by the structure, It is desirable to provide rolling means such as rollers and rollers.

As the hinge means used in the present invention, a hinge for pivotally mounting a groove cover, a locking groove provided in one of the structures,
An example is a rod that is attached to a groove lid, is fitted with a locking groove, and has a contact surface with the groove bottom and is formed of a rolling means such as a rod, roller, or roller. Among them, the latter is preferable in that the rolling means such as a rod, a roller, a roller, or the like can be mounted simply by fitting it into the locking groove, and the mounting is easy.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the supporting structure of a groove cover shown in FIGS. 4 and 5, a projecting portion 12 projecting toward a frame B of a seismic isolation structure is formed on a frame A as a structure.
An inclined surface 11 is formed so that the frame B can enter under the protruding portion. One end of the groove lid 13 is connected to the protruding portion 12 by a hinge 14 as a hinge means so as to be able to tilt up and down, and the other end is connected to a ramp 15 so as to be tiltable up and down by a hinge 16 which is also a hinge means. Have been. Rods 17 and 18 each having a circular cross section are fixed to portions where the groove cover end and the ramp end meet the inclined surface 11.

According to the present embodiment, when the skeleton B of the seismic isolation structure shown in FIG. 4 is displaced to the position indicated by the solid line or the position indicated by the alternate long and short dash line in FIG. 5, the rods 17, 18 move along the inclined surface 11, The groove lid end is supported on the inclined surface. The ramp end is also supported on the skeleton B over the inclined surface 11 or the inclined surface 11. In the example shown in FIG. 6, a plate 23 is formed in a recess 22 formed in the protrusion 21 of the frame A.
Rod 2 having a circular cross-section secured to the end of a groove cover 25 in a locking groove 24 formed between the plate 23 and
6 can be fitted. The remaining structure is the same as that of the above-described embodiment shown in FIGS.

According to this embodiment, the groove cover 25 is mounted by fitting the groove cover 25 such that the rod 26 at one end fits into the locking groove 24 and the rod 17 at the other end rides on the inclined surface 11.
Is bridged between the skeletons A and B.

[0014]

According to the first aspect of the present invention, one end of the groove cover is connected to one of the structures, so that the groove cover is pushed and moved by the traffic of the vehicle and does not fall off. Even if one of the structures is displaced relative to one of the structures, the other end of the groove cover can be dealt with by moving on the other structure. There is no risk of hindering traffic, the influence of steps at the end of the groove lid is reduced, enabling smooth running and traffic of vehicles and pedestrians. It has effects such as that.

According to the second aspect of the invention, it is possible to cope with vertical displacement of the other structure. According to the third aspect of the present invention, the groove lid can be easily attached and detached. According to the fourth aspect of the invention, the end of the groove lid can be smoothly moved.

By providing the ramp as in the fifth aspect of the present invention, there is no step with the groove lid, and the vehicle and the pedestrian can run and pass smoothly without being caught. When the ramps are connected by hinges as in the invention according to claim 6, it is possible to cope with vertical displacement of the other structure.
