Abstract

PURPOSE:To enhance the workability of application of a frame-resistance cover for a steel framed column, a steel framed beam or the like. CONSTITUTION:A frame resistant panel 2 formed with cut-grooves 3 as folding lines at its one of surfaces and bonded at its the other surface with flexible vinylon meshes 4 in parts between which the cut-grooves 3 are laid, is folded into a U-shape along the cut groove 3 as a folding line. Two panels of such kinds are attached to a steel framed column 1, surrounding the latter.

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fireproof coating structure for a steel frame such as a steel column or beam, in which a fireproof panel is attached to a steel frame such as a steel frame to form a fireproof coating covering the outer periphery of the steel frame.

0002

[Prior Art] This type of fire-resistant coating structure for a steel frame can be used for exterior coating at the same time as fire-resistant coating by simply attaching fire-resistant panels to the steel frame. Compared to attaching a decorative board to a steel frame, it requires fewer man-hours and is superior in work efficiency. Conventionally, for a steel column that is an example of such a fireproof covering structure, as shown in FIG. While they are in contact, join them together by driving 6 nails, etc.
These panels 2 were attached by nailing or the like to mounting plates 5 that were adhesively fixed to a plurality of locations spaced apart in the longitudinal direction of the steel column 1.

0003

[Problems to be Solved by the Invention] However, when using the above-mentioned prior art, if there is an unevenness in a panel whose end surface contacts the inner surface of an adjacent panel, the outer surface of that panel and the end surface of the adjacent panel become flush. If the panels were not placed in the same position, the streets would become uneven and the appearance would be very unsightly, so it took a lot of effort to adjust the groundwork to eliminate the unevenness of the panels. Furthermore, since adjacent panels are joined at the corners, the corners are inevitably weak, requiring reinforcement such as corner beads, which increases the number of work steps. In short, although the workability is better than when spraying a fireproof coating, there is still room for improvement in terms of workability. An object of the present invention is to improve workability.

0004

[Means for Solving the Problems] The features and structure of the fireproof coating structure for a steel frame according to the present invention are such that the outer peripheral corner portion of the fireproof coating includes a cut groove for bending the panel on one side of the panel. At the same time, a flexible reinforcing material is glued to the other side so as to cover the panel portion located across the cut groove, and the panel is placed at a position where the bent part at the cut groove corresponds to the outer corner corner. It is located in a state where it is attached to a steel frame structure.

[0005]

[Operation] Since the outer corner is formed by the bent part of the folded panel, in other words, the outer corner is formed by one panel, there is no misalignment of the panel parts that sandwich the outer corner. Moreover, one panel has a cross-sectional shape that is resistant to bending, such as an angle shape or a U-shape.

[0006]

[Effects of the Invention] Therefore, according to the present invention, it is possible to form an outer peripheral corner with good passage simply by attaching the panel to the steel frame.
What's more, since the panels themselves are reinforced, there is no need to reinforce the outer corners, which greatly reduces work effort and improves workability.

[Example] As shown in Fig. 1, H
This is a fireproof coating structure for a steel column 1 using shaped steel, and a fireproof coating A covering the outer periphery of the steel column 1 is formed by attaching a fireproof panel 2 to the steel column 1. As shown in FIG. 2, the panel 2 has cut grooves 3 for bending the panel having a V-shaped cross section extending from the upper end of the panel to the lower end of the panel on one side of each of two locations in the width direction. On the other side, vinylon mesh 4, which is an example of a flexible reinforcing material, has a width spanning the panel portion located across the cut groove 3, and is glued so as to extend from the top edge of the panel to the bottom edge of the panel. It is configured so that it can be bent into a U-shape using the groove 3 as a folding line, and is formed into a U-shape by adhesively fixing the opposite side surfaces 3a, 3a of the cut groove 3 that come into contact with each other during bending. And the fireproof coating A is
Two U-shaped panels 2 are arranged with their opposing pieces 2A overlapping the outside of the flange 1A of the steel column 1 and forming a rectangle as a whole, and placed above and below the steel column 1. The connecting plate part 2B of the panel 2 is fixed to the attached mounting plate 5 at a spaced interval with nails 6, etc., and the end of the opposing piece 2A is fixed with the nail 6 to the mounting bar 7 glued to the outer surface of the flange 1A of the steel column 1.
etc., and is configured in a fixed manner.

[Another Embodiment] [1] The U-shaped panel 2 shown in the above embodiment is arranged so that the connecting plate portion 2B is parallel to the flange 1A of the steel column 1, as shown in FIG. The fireproof coating A is constructed by installing the steel frame and attaching it to the steel column 1.

[2] As shown in FIG. 4, a cut groove 3 is formed at one location in the width direction of the panel 2, and a reinforcing material 4 is bonded to form an L-shaped panel 2. The fireproof covering A is constructed by arranging the four pieces at the outer peripheral corners and attaching them to the steel column 1.

[3] As shown in FIG. 5, cut grooves 3 are formed at four locations in the width direction of the panel 2, and reinforcing materials 4 are bonded to form the panel 2 into a rectangular shape that covers the entire circumference of the steel column 1. This is attached to the steel column 1 to constitute the fireproof covering A. In this case, the panel 2 will be bent so as to wrap around the steel column 1.

[4] In the above embodiment, application to the steel column 1 was shown, but the present invention can also be applied to a steel beam. In the case of a steel beam, a total of three sides, both sides and the bottom of the beam, will be covered.

[5] In the above embodiment, an H-shaped steel column is shown as the steel frame 1, but the shape of the steel frame 1 can be changed as appropriate.

[6] In the above embodiment, the rectangular fireproof coating A is shown, but in the present invention, the fireproof coating A can also be configured to have a triangular, pentagonal or more polygonal shape.
