Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a plate enclosure structure surrounding columns such as H-shaped steel or square steel, and particularly relates to a plate enclosure structure for columns when installed in a fire-resistant coating structure. .

[Conventional technology]

Conventionally, in buildings made of steel frames, columns made of H-shaped steel or square steel must be coated with a fire-resistant coating by wet spraying in order to have a fire-resistant structure. However, if it is only sprayed to a predetermined thickness, it will not be finished as an interior decoration, so it must be further plastered, but cracks easily occur due to earthquakes, etc.

Therefore, it was necessary to spray a fireproof coating, let it dry, and then surround it with boards, etc., making the work complicated.

Therefore, as shown in FIG. 3, it has been proposed to surround the H-shaped steel using a fire-resistant coated molded plate.
Note that an explanation will be given here using an H-shaped column as an example.

In the same figure, 3 is an H-shaped column made of H-shaped steel.
This consists of parallel facing plates 1, 1 and a connecting plate 2 bridging the center of each facing plate 1, 1. Reference numerals 14 and 15 are formed from fire-resistant coated molded plates, and 14 is a side plate that covers the outer surfaces 1a and 1a of both opposing plates 1 and 1 of the H-shaped pillar 3,
Reference numeral 15 denotes a face plate that is attached to bridge the ends of the opposing plates 1,1. Reference numerals 16 and 17 indicate waste plates that serve as a base for attaching the side plates 14 and face plate 15, and 16 and 17 are disposed on the outer surface 1a side of the opposing plate 1, and 17 is an H-shaped column 3. It is arranged so as to fit into the recesses 1d, 1d formed in the. These sacrificial plates 16 and 17 are fixed to the H-shaped column 3 with adhesive. Said side plate 14
is attached to the sacrificial plate 16 with screws 14b, and the face plate 1
5 is attached to the sacrificial plate 17 with screws 15b. In this way, the H-shaped column 3 is surrounded by the side plate 14 and the face plate 15 and constructed as a fire-resistant square column.

[Problem that the invention attempts to solve]

However, in the conventional pillar plate enclosure structure, the waste plates 16 and 17 must be cut to match the actual size of the H steel on site, which requires labor and inaccurate dimensional angles. Since it is fixed to the H-shaped pillar 3 through
7 was more likely to peel off than the H-shaped pillar 3, which caused a problem in the fixing force of the side plate 14 and face plate 15, resulting in low structural reliability.

Therefore, the object of the present invention is to obtain a plate enclosure structure for columns made of H-shaped steel, square steel, etc., which is structurally highly reliable.

[Means for solving problems]

The plate enclosure structure of the column of the present invention is located on both sides 1f, 1f sides of the outer surfaces 1a, 1a of the opposing plate 1 of the column 3, and the upper and lower ends are fitted into upper and lower horizontal runners 6, 7 having a U-shaped cross section. Studs 9 and 10 are provided on which the sacrificial board 8 is attached to the opposing board 1 side, and these studs 9,
10, the side edges 4a and 5a of the side plate 4 and face plate 5 were fixed.

[Effect]

Since a sacrificial board such as gypsum board is interposed between the studs 9 and 10 and the facing board 1, even if the studs 9 and 10 are pushed from the side board 4 side, this does not directly hit the facing board 1, so no metallic sound is generated. , the studs 9 and 10 do not move at all because they are supported by a sturdy facing plate.

Further, the ends of the face plate 5 are attached to the studs 9, 10, and the studs 9, 1 are attached immediately adjacent to the studs 9, 10.
Since the edge of the opposing plate 1 is along the mounting surface of the face plate 5, the studs 9,
10 deflection does not occur at all. Therefore stud 9,
There is no need to increase the thickness or dimensions of the plate 10 or to provide reinforcement.

[Example of idea]

Hereinafter, the column enclosure structure of the present invention will be explained based on FIG. 1 of the drawings. Incidentally, the same parts as those in the conventional example shown in FIG. 2 are designated by the same reference numerals, and the explanation thereof will be omitted.

In the figure, 4 and 5 are made of fire-resistant coated molded plates, 4 is a side plate that covers the outer surfaces 1a and 1a sides of both opposing plates 1 and 1, and 5 is a bridge between the tips of both opposing plates 1 and 1. The figure shows the face plate installed as shown in the figure. 6 and 7 are upper and lower horizontal runners with a U-shaped cross section, and 8 is a waste board. 9 and 10 are the outer surfaces 1a of the opposing plate 1 of the H-shaped column 3;
It is a stud provided so as to be located on both sides 1f and 1f side of 1a, and on the inner side, that is, on the opposing plate 1 side, a sacrificial plate 8 is attached with screws 8b.

The upper and lower ends of the studs 9 and 10 are fitted into the upper horizontal runner 6 and the lower horizontal runner 7. 11 is hole 1
The upper and lower ends are fixed to the lower horizontal runner 17 and the upper horizontal runner (not shown), which are fixed to the floor and ceiling by riveting via 7a, and auxiliary studs 12 serve as the base of the face plate 5, and 12 is connected to the side plate 4. Side edges 4a, 5a of face plate 5
It is a corner bead that covers.

Next, the construction order will be explained.

First, the upper and lower horizontal runners 6 and 7 cut to approximately the same length as the width of the opposing board 1 are fitted so as to bridge the upper and lower ends of the studs 9 and 10 cut to the length from the floor to the ceiling. A frame-like frame having approximately the same external shape as the outer surface 1a of the facing plate 1 is made by combining them, and a waste plate 8 is placed on one side.
Attach with screw 8b.

A frame body made up of the studs 8, 9, runners 6, 7, and sacrificial plate 8 is placed against the outer surface 1a of the opposing plate 1 so that the sacrificial plate 8 side is in contact with the outer surface 1a side. Then, fix the upper and lower horizontal runners 6 and 7 to the ceiling and floor sides, respectively, with studs 7a.
Fix it with etc. A stud 11 whose upper and lower ends are fitted into a lower horizontal runner 17 and an upper horizontal runner (not shown) is installed between the ends of the opposing plates 1 and 1.

Note that it is not necessary to use this stud 11 depending on the size of the H-shaped steel. The side plates 4 and face plate 5 made of fire-resistant coated molded plates are pasted onto the base thus provided. That is, both ends of the side plate 4 are connected with screws 4.
b to the studs 9 and 10, and the face plate 5 is attached to the sides of the studs 9 and 10 and the auxiliary stud 11 by fixing both ends and the center with screws 5b and 15b. Finally, corner beads 12 are attached to the squares of the butt portions of the side plates 4 and the face plates 5 for reinforcement.

In the above embodiment, a structure surrounding a column made of H-shaped steel was described, but the present invention can also be applied to a structure surrounding a rectangular column as shown in FIG.

[Effect of idea]

As explained above, in the plate enclosure structure of the H-type steel or square steel of the present invention, the studs are provided in close contact with both ends of two opposing sides of the H-type steel or square steel through the sacrificial plate, so that the studs and Since there is no direct contact with steel, there is no metallic noise, and there is no deflection of the studs due to external pressure. Therefore, there is no need to reinforce the studs, and the thickness and dimensions of the studs can be reduced to reduce costs.
