Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing a suspended floor from rolling.

2. Description of the Related Art It has been considered to arrange a stage-type floor in a large space in a building to give an accent to the space. As such a structure, hanging columns are suspended from beams constituting a structure of a building, and a floor frame is supported at a lower end of the hanging columns.

Problems to be Solved by the Invention In the above, the floor with accents may have an adverse effect on a rather heavy one, for example,
If there is a pillar below the floor, the space will be unnecessarily limited. Therefore, it is preferable that the floor is used as a suspended floor and the mounting is not large. Therefore, a suspension pillar that supports the floor is also lightweight and easy to mount, but this has the disadvantage that the floor is liable to roll. The present invention is such that the floor can be rolled with a simple structure.

Means for Solving the Problems In order to solve the above problems, according to the present invention, a U-shaped or U-shaped support is projected from the floor frame to the side thereof, and a floor frame is provided between the support pieces of the support. The vertical plate of the lateral beam or column is interposed, and the vertical plate is clamped by the tip of a bolt screwed in from the side of the support.

Similarly, in the second invention of this application, a pair of holding plates are vertically extended across a side surface of a floor frame suspended and supported via suspension columns and both vertical plates of beams or columns on the side of the floor frame. The vertical plate is clamped by the tightening force of bolts which are arranged on the left and right sides of the plate and are inserted across the holding plate.

In the above-mentioned structure of the present invention, in the first invention, first, a beam or column plate is interposed between the support pieces of the U-shaped or U-shaped support tool projecting to the side from the floor frame. To prevent the floor from swaying while being clamped by bolts screwed into the support.

Further, in the second invention, the floor frame is supported by the holding plate straddling the vertical plate of the structural body and the vertical plate of the floor frame, and the roll is prevented.

Embodiment An embodiment of the present invention will be described below together with the floor mounting structure.

FIG. 11 shows the mounting structure of the floor frame.
Reference numerals 1 and 1 denote structural beams of a building made of H-shaped steel and arranged such that the flanges 2 and 2 are vertically parallel. Are structural pillars of a building, which are also made of H-shaped steel, and whose flanges 4 and 4 are installed so as to be parallel to the left and right. At the center of the web 5, strip-shaped rib plates 26 and 26 are flanged. The web 5 is welded in advance to the front and back surfaces of the web 5 in parallel with 4, Although not shown in this figure, beam 1
It is attached across the upper end of the pillar 3. 6 is a floor frame,
Four H-shaped steels are joined in a rectangular frame shape, and the flanges 7 of the H-shaped steels are welded to each other so as to be vertically parallel. In this figure, the left front side of the figure is the floor front side, and first, on the rear side, the vertical plate 11 at the upper end of the suspension pole 10 is fixed to the stiffener plate 9 whose upper part is welded to the side of the web 8 of the beam 1. The horizontal plate 12 at the lower end of the suspension column 10 is fixedly supported on the upper surface of the floor frame 6. On the other hand, also on the front side, a pipe-shaped suspension pillar 13 having its upper end fixed to the side surface of the upper beam 1 is hung downward, and the floor frame 6 is supported at its lower end.

FIG. 12 and FIG. 13 show a detailed mounting structure of the suspension pole 13 supporting the front side, and a slit 14 is formed at an upper end of the suspension pole 13 over a certain length from the end face thereof.

A bolt 37 screwed into the support piece 29 from outside the bent portion 35
Are brought into contact with the flange 4 to clamp the flange 4 therebetween.

In the floor frame 6 attached as described above,
As shown in FIGS. 6 to 8, a plurality of band-shaped bars 40, 40... Are arranged in parallel, and the bars 40, 40. However, it is attached so as to cover the entire space in the floor frame 6. The grating material 42 is installed with both ends of the crosspiece 40 mounted on the upper surface of the flange 7 below the floor frame 6. A plurality of bolts 44 are welded to the upper surface of the flange 7 in an upright state in advance, and the bolts 44 are arranged so as to protrude into the gap between the crosspieces 40, 40.
45 is a holding metal bent into an inverted Ω shape when viewed from the side, and both right and left pieces are placed over the upper surface of the crosspiece 40 adjacent to each other, and the bolt is formed in a bolt hole formed in the center part. Insert the tip of the bolt 44, fit the holding bracket 45 outside the bolt 44, and further tighten the nut 46 screwed to the tip,
The holding member 45 presses and fixes the grating material 42. FIG. 10 is a view of the floor frame 6 as viewed from below, and the grating material 42 forms a pattern on the back surface of the floor.

Next, on the upper surface of the grating material 42, a top plate 48 made of a color plywood or the like, a plurality of tree joists 49, a base plate 50 made of a particle board or the like, and a floor plate 51 made of a large number of flooring materials are attached in order from the bottom. . First, a support plate 52 made of a thin metal plate is attached by welding in advance over the upper surfaces of the pair of parallel bar members 40, 40 of the grating member. Then, the top plate 48 is placed on the upper surface of the support plate 52, and a screw 54 is inserted from below into a screw hole 53 formed in the center of the support plate 52, and the tip is screwed into the top plate 48. I am trying to fix it.
The wooden joists 49 installed on the upper surface of the top plate 48
Is fixed by screws 55 screwed from below. Furthermore,
A base plate 50 is laid on the upper surface of the joist 49, and the floor plate 51 is placed thereon. On the end faces of these floorboards 51, ridges 56 are formed on one side and grooves 57 are formed on the other side,
These are fitted to each other. At this time, the ridge 56 of the floor plate 51 arranged at the end is fitted into the lower surface of the upper flange 7 of the floor frame 6 to prevent the floor frame 6 from floating upward. In addition, the grating material
The floor components from 42 to the floor plate 51 are accommodated within the range of the thickness of the floor frame 6 so as not to protrude from the floor frame 6.

Effect of the Invention As described above, according to the present invention, a beam or column plate is interposed between support pieces of a U-shaped or U-shaped support tool projecting laterally from a floor frame, and the support tool is provided. This structure prevents the floor from swaying in the state of being clamped by bolts screwed into the plate, so that it can be easily mounted simply by screwing the bolts through the plate.
In addition, a structure such as a beam or a column only needs to have a vertical plate that is usually mounted, and there is no need to perform significant remodeling or processing. On the other hand, also in the second invention of this application, it is only necessary to mount the pair of holding plates over the structure such as the pillar and the vertical plate of the floor frame and tighten the bolts, and the same effect is obtained.
