DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body fixing plate used for fixing a vehicle body via a stand when repairing a deformed vehicle body or the like of an automobile.

[0002]

2. Description of the Related Art A conventional vehicle body fixing plate 1 of this type is
As shown in FIG. 4, a large number of pedestals 4 for bonding and fixing to a concrete floor 3 are welded to the lower surface of a plate body 2 formed of a steel plate having an elongated rectangular shape and a relatively large thickness, for example, about 12 mm. It is provided. In addition, 1 along the longitudinal direction penetrating up and down at the center in the width direction of the plate body 2.
In addition, a number of long holes 5 are formed, and a large number of other small holes 6 are formed, for example, ten. In this example,
Twelve pedestals 4 are provided, each of which has a central hole 8 with a counterbore 8 through which one anchor bolt 7 is inserted, and two horizontal screw holes on both sides of the hole 8. A male screw 9 is screwed into the screw hole so as to protrude downward. This body fixing plate 1 has a length of 1500
4 mm are used as a set, and the anchor bolts 7 and the male screws 9 are used, for example, so that two sheets are parallel to each other on both sides at approximately wheel intervals of a normal car so that they are continuous in the longitudinal direction and the upper surface is horizontal. At the desired location on the floor of the workplace. FIG. 5 shows a use form of the vehicle body fixing plate 1, in which the vehicle body 1
1 is fixedly supported in a state of being lifted from the floor surface. The stand 10 for supporting the vehicle body is disposed so as to straddle the long hole 5 and is fixed to the plate 1 using a metal fitting that engages with the long hole 5. Each stand 10 is connected to the vehicle body 11 by an upper clamp 12, and is integrally connected to each other by combining two vertical beams 13 and two horizontal beams 14 connecting each other in a cross-girder shape. .

In repairing a vehicle body using such a vehicle body fixing plate 1, a deformed portion of the vehicle body is pushed or pulled to cause a composition deformation to be repaired. For example, one end is connected to the vehicle body. The chain is pulled using a lever block or a hydraulic cylinder. In this case, the direction of pulling and the point of attachment vary depending on the deformation of the vehicle body. In order to support this pulling reaction force, the other end of the chain connected to the lever block, the other end of the chain connected to a pulley installed at an appropriate position for adjusting the pulling direction, the pulley, etc. When it is necessary to fix and support, and when the point of application of the portion where such a reaction force acts is on the floor side, an appropriate position is selected from a large number of long holes 6 of the plate 1 and selected. Engage a special hook,
The end of the chain is connected to this hook, or the chain is hung on a pulley formed integrally with the hook, and the long hole 5 is used for fixing the stand, and the long hole 6 is used for pulling substantially downward. It is designed to be used as a reaction force application part.

[0004]

However, in an actual operation, the elongated hole 5 for fixing the stand is often used as a point of application for supporting the above substantially downward pulling force. Since a large pulling force is often applied in order to repair the vehicle body, when used to a certain extent, the opening edge of the long hole 5 of the plate body 2 undergoes plastic deformation in a state of being partially displaced upward, and the stand 10 There is a problem that the upper surface on which the camera is mounted is not flat and a good stand cannot be installed. The stand 10 is installed on a horizontal surface, and the vehicle body is fixed and supported in a horizontal posture.
Since the purpose is to repeatedly perform the plastic deformation for measuring and repairing the vehicle body, it is extremely inconvenient for the measuring operation that the upper surface supporting the stand is not horizontal.
Although the deformation of the plate 1 is caused by insufficient strength, the body fixing plate 1 originally installed on the floor of this type is characterized by its simplicity. Doing so is not preferable because it increases the weight and makes the moving operation for transportation and installation inconvenient.

It is an object of the present invention to provide a vehicle body fixing plate which can prevent deformation of a stand support surface and can be easily installed.

[0006]

According to another aspect of the present invention, there is provided a fuel cell system having a groove formed by both side walls and a bottom wall, and having an engaging edge protruding inward at an upper end of the both side walls so as to face each other. A groove-shaped member having a fixing wall with a bottom wall extending outward on both sides and having an anchor bolt hole formed therein, the cross-sectional shape of which is uniform in the longitudinal direction and has a predetermined length, and fixing of the groove-shaped member on both sides. An upper surface formed by the engagement edge formed by extending a predetermined width outward in the width direction by partially overlapping each other on the upper side of the use edge portion, and having an upper surface located outside the fixing edge portion. And an upper surface extending member on both sides having an anchor bolt engaging portion (claim 1).

The means of the present invention is used, for example, by placing it on a flat concrete floor and fixing it with anchor bolts. In handling up to the installation, since the groove-shaped member and the upper surface extension members on both sides are formed separately, the weight per unit is small and easy to handle. In its use, a hook-shaped member can be engaged with the engaging edge of the channel member to exert a substantially upward force. That is, the upward force can be sufficiently counteracted by the presence of the side wall and the bottom wall connected to the engaging edge. Compared with a conventional flat plate in which a long hole is formed and an edge of the long hole is used as an engaging edge, the engaging edge of the means of the present invention is remarkably stronger in strength in that it has a configuration continuous with the side wall and the bottom wall. It is excellent and is not easily deformed even when an upward force such as pulling up a part of the engaging edge acts.

[0008] The channel member is formed of hot extruded die steel (Claim 2).
The grooved member can also be formed by cutting and welding a plate material, but the cross-sectional shape (mainly the size of the radius at the corner of the inner surface of the groove) that affects welding, removal of distortion, and strength is preferable. In view of the production cost, the hot extruded material is more advantageous in view of the formation cost. With this configuration, it is possible to obtain a vehicle body fixing plate that is excellent in strength and has very little variation in strength.

A screw hole is formed in the fixing edge at both sides of the anchor bolt hole, and a male screw for horizontal adjustment is screwed into the screw hole so as to protrude from the lower surface of the fixing edge. There is a feature (claim 3). In this configuration, when fixing the channel member to the floor with anchor bolts,
The level of the upper surface of the groove-shaped member can be adjusted by operating the male screw screwed into the screw hole.
