Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a notch cover in a steel floor slab, which is a plate formed in a grid shape from a metal strip steel plate and is used for a groove lid or the like. Also applies.

[0002]

2. Description of the Related Art Steel floor slabs are connected to each other in the width direction for the purpose of distributing the loaded load to adjacent steel slabs and increasing the strength of the entire steel slab. It is done by tightening the sides of the steel floor slab with the bolts of
When connecting from the top surface of the steel floor slab, a notch is provided in a part of the top surface of the steel floor slab to set the bolt or insert the tool to perform the work. It was left open.

Therefore, when a pedestrian passes over the steel floor slab, it may be dangerous because it may trip over the notch, or the tire of a passing vehicle such as a bicycle or an automobile may reach the notch. When it fell, an impact was generated and the driver was uncomfortable.

Further, since the notch is exposed, dirt, dust, and the like adhere to the threaded portion of the bolt, and during regular inspection, these must be removed before loosening the bolt to open the panel. The workability was extremely poor.

Further, when fixing the steel floor slab and the receiving beam by bolts, it is necessary to provide a notch portion, and there are similar drawbacks. In this case, however, the steel plate is more U-shaped than in the past. There is only a method of inserting a cover that has just been bent into the notch, and this cover causes a metallic noise when the vehicle is passing, which is a noise problem.

[0006]

SUMMARY OF THE INVENTION Therefore, the present invention eliminates the above-mentioned drawbacks and covers the opening of a steel floor slab with a notch cover to prevent the steel floor slab from coming off due to vibration when the vehicle is passing. Provided is a notch cover in a steel floor slab that does not generate noise and can be easily removed.

[0007]

The cutout cover of the present invention is a cover formed in the shape of a box without a bottom, and is actually owned by the applicant of the present invention, which can be firmly fixed to the periphery where the cutout is formed. This is a device in which the noise control device of the grooved lid disclosed in Japanese Patent Publication No. 59-12310 is used as a clip.

[0008] In addition, a pulling hole or a notch is provided on the upper surface of the notch for easy attachment and detachment, and a feature is added so that it can be easily removed by inserting a handy tool such as a screwdriver and prying. Is.

Further, the notch is provided at the clip mounting position on the side wall portion of the notch cover so that the seating of the cover can be stably performed without floating by the clip, and the positioning when mounting the clip is easy. The feature is that it can be done.

When connecting steel floor slabs in the width direction,
As shown in FIG. 1, when a receiving seat is provided in the cutout portion of the steel floor slab to fix the cutout portion cover in a stable state, and when the steel floor slab and the receiving beam are fixed by bolts, the case shown in FIG. As shown in, a peripheral wall formed by cutting a channel material, a square pipe material, or the like into a ring is attached to the base plate, and the notch portion is covered with a longer side wall portion than the notch portion cover shown in FIG.

[0011]

In the present invention, the utility model number 59-1 owned by the applicant of the present application
Since the groove lid noise suppressor disclosed in Japanese Patent No. 2310 is used as a clip, the peripheral wall of the steel floor slab forming the notch and the notch cover can be firmly fixed, and the notch part The cover is stably placed on the receiving seat or the base plate, does not come off due to vibration when the vehicle passes, noise can be prevented, and it can be easily attached and detached during inspection. It can be easily removed by providing a drawing hole or notch on the upper surface of the notch cover and inserting a handy tool such as a screwdriver to pry.

[0012]

EXAMPLE Next, one embodiment of the present invention will be described in detail with reference to FIG. 1. When connecting steel floor slabs to each other in the width direction, a connecting bolt for attaching a connecting bolt to the steel floor slab (1) is used. The notch (X) is provided on the upper surface of the steel floor slab (1), the receiving seat (2) is provided at the bottom of the notch, and the notch (X) is provided in the notch (X). Block (X), and
A notch cover (3) whose upper surface is flush with the upper surface of the steel floor slab (1) is provided, and clips (4) are attached to opposite side surfaces of the notch cover (3). And the clip (4) is attached to the steel floor slab (1) to form a notch (X) by press fitting the steel floor slab (1) with the peripheral wall and the notch cover (3). And can be firmly fixed on the receiving seat (2) through the clip (4).

Further, another embodiment of the present invention will be described in detail with reference to FIG. 2. In the case of fixing the steel floor slab (1 ') and the receiving beam (Y) with the bolt (Z), the steel floor slab is fixed. In order to attach the fixing bolt (Z) to (1 '), the notch (X') is provided on the upper surface of the steel floor slab (1 '), and the base plate (5) of the steel floor slab (1') is used. Then, a peripheral wall is attached with a channel material (6) at a lower position where the cutout portion (X ′) is located, and clips (4) are attached to both sides of the channel material (6) on the cutout portion cover (3 ′). By press-fitting into the steel floor slab (1 ') while mounted on the wall, the peripheral wall and the notch cover (3') formed by the channel material (6)
Can be firmly fixed via the clip (4), and the notch cover (3 ') is stably arranged on the base plate (5).

The notch cover (3 ') may be provided with a pull-out hole or a notch for facilitating attachment and detachment so that a handy tool such as a screwdriver can be easily inserted and removed. , The cutout portion cover (3)
Concavities and convexities may be formed on the upper surface of each of (3 ') to prevent slipping.

[0015]

According to the present invention, the notch portion of the steel floor slab has the following features.
There is no danger of pedestrians tripping and getting injured because it is covered with a notch cover, and even for passing vehicles such as bicycles and automobiles, since the notch cover is covered by the notch cover, there is no impact. Does not occur, and since earth and sand and dust do not directly adhere to the connecting bolts or the fixing bolts, the bolts can be removed easily and periodic inspections can be performed easily.

Further, since the notch cover is firmly fixed by the clip, it does not come off due to vibration when a vehicle or the like is passing, noise can be prevented, and the upper surface of the notch cover is pulled out. If the hole or notch is formed, it can be easily attached and detached using a handy tool such as a screwdriver.

Further, by forming the unevenness on the surface of the notch cover, it is possible to obtain an extremely beneficial effect such as not impairing the slip preventing effect of the steel floor slab.
