Description

[Detailed description of the invention] a. Field of industrial application The present invention relates to a mounting member for a steel frame fireproof coated structure, and in particular, it provides a sufficient fireproof structure through simple construction and is equipped with a fireproof board that also serves as a finishing material. Concerning new improvements to make it possible.

b. Conventional technology A variety of configurations have been adopted for this type of steel frame fireproof coating structure that has been used in the past, but generally fireproofing materials are mixed with water and adhesive and sprayed directly onto the surface of the steel frame. There are two main types of construction methods: wet construction methods, in which fireproofing is applied or coated, and dry construction methods, in which plate-shaped fireproofing materials are cut into the desired shape and then attached and covered using adhesives, nails, etc.

In addition, as a document disclosing such a steel frame fireproof coating structure, there is Japanese Patent Application Laid-Open No. 1989-1989 proposed by the present applicant.
33965 and JP-A-61-126252 can be disclosed.

That is, in the configuration disclosed in Japanese Patent Application Laid-open No. 60-33965, although not shown in the drawings, the L
The jig is formed around the beam using a steel frame fireproof covering jig, which is constructed by connecting a plurality of jig members shaped like a letter so as to be slidable so as to surround the beam.

Once this jig was set up, a fireproof board was attached to the outside of the jig.

In addition, in the configuration disclosed in JP-A No. 61-126252, although not shown in the drawings, a foldable fireproof board is cut to a length that can be fitted to the H-shaped steel. A fireproof board was attached as a spacer to the groove-shaped part of an H-beam or steel column, and finishing material was attached to the outside surface.

c. Problems to be solved by the invention Since the conventional steel frame fireproof covering structure is configured as described above, it has had the following problems.

(1) First, in the case of the above-mentioned wet construction method, the outer surface of the steel frame became uneven, making it extremely difficult to attach interior finishing materials in the subsequent process.

(2) In addition, in the case of the dry construction method described above, since the fireproof board made of extremely lightweight material was used for installation, the impact resistance during the fireproof test was not sufficient.

Furthermore, it had to be cut on site to match the shape of the steel frame, which was time-consuming and increased costs.

Furthermore, the strength of the fireproof board is low and the surface is rough, so it could not be used as an interior finishing material.

(3) In addition, in the case of the configuration disclosed in JP-A No. 60-33965, it is necessary to cover the surroundings of the H-shaped steel and steel columns with a covering jig, and when applying it to the steel frame of the entire building, It was time-consuming and costly, and there were problems with practicality.

(4) Also, in the case of the configuration disclosed in JP-A-61-126252, the spacer is cut and attached to the steel frame,
Since the fireproof board is installed directly on top of this spacer, the fireproof board and the steel frame are almost connected to each other, and if there is a problem with the verticality or horizontality of the steel frame construction, sufficient finishing accuracy cannot be adjusted.

This invention was made to solve the above problems, and in particular, it is a fireproof steel frame that has a sufficient fireproof structure with simple construction and can be fitted with a fireproof board that also serves as a finishing material. The purpose is to obtain a mounting member for a covered structure.

d Means for solving the problem The mounting member for steel frame fireproof coating structure according to the present invention is as follows:
A mounting member for a steel frame fireproof covering structure that connects a bar member having an opening groove in the longitudinal direction and a connecting member disposed perpendicularly to the bar member, which has a generally long plate shape as a whole and extends in the same direction. a main body consisting of a holding part and a tongue piece; a fitting part formed on the holding part in a direction perpendicular to the surface of the holding part and fitting into the opening groove of the bar member; and the tongue piece. a pair of L-shaped protrusions that protrude outward along the surface of the tongue piece from the longitudinal side thereof and have a clamping part that clamps the connecting member at the end thereof,
The holding portion is formed in a direction perpendicular to the surface of the tongue piece.

e Effect In the mounting member for a steel frame fireproof sheathed structure according to the present invention, when the fitting portion is fitted into the opening groove of the bar member, the tongue piece is attached in a direction perpendicular to the position of this opening, that is, toward the other bar member. Therefore, when a connecting member is inserted and held in this tongue piece, the connecting member can be provided between each bar member very easily and can function as a beam. Therefore, with this attachment member, a connecting member can be easily provided between each bar member.

f. Embodiments Hereinafter, preferred embodiments of the mounting member for a steel frame fireproof covering structure according to the present invention will be described in detail with reference to the drawings.

In the drawings, the reference numeral 1 indicates a mounting member for a steel frame fireproof coating structure (hereinafter referred to as the mounting member). , a main body portion 4 consisting of a holding portion 2 and a tongue piece 3 extending in substantially the same direction.
A pair of fitting parts 5 are formed at both ends of this holding part 2 in a state of bending and protruding in a direction perpendicular to the surface of this holding part 2.

These fitting parts 5 are formed with mounting holes 5a for guiding nails, screws, etc.

Furthermore, a pair of protrusions 6 are provided on the holding portion 2 side of the tongue 3, which protrude from the longitudinal side 3a of the tongue 3 in a direction perpendicular to the outside along the surface of the tongue 3. These protrusions 6 are generally L-shaped in their entirety, and have a pair of clamping parts 6b formed in a direction perpendicular to the surface of the tongue piece 3 at their ends. has mounting hole 6a
is provided.

Next, the configuration shown in FIGS. 2 to 4 uses the mounting member 1 and the second and third mounting members 7 and 8 to form a U-shaped bar member around a steel frame 9 made of H-shaped steel. 10 and the connecting member 11 are shown attached. First, each second mounting member 7 is welded.
