Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a vehicle body floor plate mounting portion structure for mounting a bolted component such as a rope hook to a vehicle body floor plate, and particularly to a space between adjacent ridges of the vehicle body floor plate. By welding a bracket with a step and a mounting part on the floor, the floor surface is flattened, the floor plate mounting part is rustproofed, and the dead space between the adjacent ridges of the floor plate is effectively used. In addition, the present invention relates to a method for increasing the rigidity of the floorboard.

[Conventional technology]

In this type of vehicle floor plate mounting structure, conventionally, the parts are fastened to the floor pan by a weld nut and bolts welded to the lower surface of the bolt holes drilled in the floor pan, and the front part of the weld nut is fastened. It is known that a downward projection is formed on the floor pan at the position, and the projection is used to waterproof the component mounting portion (for example, see Japanese Utility Model Laid-Open No. 59-129677).

[Problems to be solved by the device]

In the conventional body floor plate attachment structure, the projection formed downward on the floor pan at the front position of the weld nut provides a temporary waterproof effect for water that travels from the front to the rear on the bottom surface of the floor pan. Although you can expect it, you cannot expect the waterproof effect of the water splashed by the tire, and the water adheres to the weld nut and the tip of the bolt to cause rust, and the floor pan also has a bolt hole. Since there are holes in the weld nut, there is a problem that water will leak due to infiltration water from the non-welded part of the weld nut, and rust will occur in the parts mounting part. There is a problem that the rigidity of the is reduced.

The present invention solves the above-mentioned problems of the prior art. By welding a bracket having a step portion and a mounting portion between adjacent ridges of a vehicle body floor plate, the floor surface is flattened and the vehicle body floor plate is also designed. It is not necessary to provide any mounting holes on the floor to prevent rust at the floor plate mounting portion, and by positioning the mounting holes between the adjacent ridges, the dead space between the adjacent ridges is effectively used. Also, an object of the present invention is to provide a vehicle body floor plate mounting portion structure capable of increasing rigidity of the floor plate by connecting adjacent ridges with a bracket.

[Means for solving the problem]

In order to achieve the above object, in the body floor plate mounting portion structure of the present invention, mounting holes are formed between the adjacent ridges of the floor plate in which the concave lines and the concave lines are alternately formed continuously. A bracket having an attached mounting portion and a step portion continuously provided on both sides of the mounting portion is laid across the recessed line by welding, and the mounting portion is formed by each step portion with respect to the protruding line. Are recessed.

[Action]

The mounting structure of the vehicle body floor plate configured as described above,
Since a bracket having a mounting hole in the center is welded between the adjacent ridges of the floor plate formed on the uneven strip, it is not necessary to provide any mounting hole on the vehicle body floor plate and the bolted The bracket having the mounting hole, which is a mounting portion of the component, is completely shielded from the lower portion of the vehicle body floor plate, which is the outside of the vehicle body, and does not come into contact with water outside the vehicle.

In addition, since the mounting portion where the mounting hole of the bracket is bored is recessed by the step portion between the adjacent ridges, when the bolted parts are mounted in the mounting hole with the bolts and nuts, Since the bolts and nuts are built into the recessed dead spaces between adjacent ridges, they do not protrude above the protruding ridges of the vehicle body floor plate, so they do not interfere with the use on the vehicle body floor plate, and the recessed groove dead space is effective. Can be used.

Furthermore, since the bracket is installed between the adjacent ridges of the vehicle body floor plate, since the adjacent ridges are connected by the bracket, the rigidity of the vehicle body floor plate can be increased.

〔Example〕

An embodiment will be described with reference to the drawings. Reference numeral 1 is a floor plate of a vehicle body, and the floor plate 1 is composed of concave ridges 2 and convex ridges 3 alternately connected by step portions 4.

On the other hand, the bracket 5 includes a mounting portion 6 at the center, welded portions 7 and 7 at both ends, and step portions 8 and 8 between the mount portion 6 and the welded portions 7 and 7.
And the mounting part 6 has a step part 8,8 for each weld part 7,7.
The mounting hole 9 is provided at the center of the mounting portion 6 by
And a nut is attached to the lower surface of the mounting hole 9.
10 is welded.

The welded portions 7, 7 at both ends of the bracket 5 are welded to the upper surfaces of the adjacent ridges 3, 3 of the floor plate 1, and the lower surface of the nut 10 welded to the mounting portion 6 of the bracket 5. Has a gap with respect to the concave portion 2 of the floor plate 1, and each step portion 8 of the bracket 5 is brought into contact with each step portion 4 of the floor plate 1, and the corresponding contact portion is welded if necessary. It is something.

The mounting structure of the vehicle body floor plate in the embodiment is configured as described above, and for example, the rope hook 11 can be attached to the mounting portion 6 of the bracket 5 by tightening it with the bolt 12, and the nut 10 and the bolt 12 of the mounting bracket. The front end of the bolt 12 can be built in the dead space of the recess 2 of the floor plate 1, and the head of the bolt 12 can be immersed in the dead space of the recess 2 of the floor plate 1 as well.

Reference numeral 13 is a wheel house integrated on the side of the floorboard 1.

[Effect of device]

The present invention is configured as described above, and since the bracket having the mounting hole that is the mounting portion of the bolted component is installed by welding between the adjacent ridges of the floor plate, the bracket Since it is completely cut off from the lower part of the car body floor plate, it is possible to prevent rusting of the mounting part of the bolted parts.Also, the mounting part where the bracket mounting hole is drilled has a step between adjacent ridges. Since the bolts and nuts are mounted in the mounting holes with bolts and nuts, the bolts and nuts are built into the recessed dead space between the adjacent ridges, so Since it does not protrude to the upper surface of the convex strip of the vehicle body, it does not interfere with the use on the floor plate of the vehicle body, and the dead space of the concave strip can be effectively utilized, and the bracket is installed between the adjacent convex strips of the vehicle body floor plate. Since those who are, for next 設凸 conditions are connected by the bracket, in which it is possible to achieve the rigidity of the vehicle body floor.
