[Problems to be Solved by the Invention] However, in the case of applying a fireproof coating to a steel frame such as a beam or column of such a steel frame structure,
In the fireproof coating method in which the steel frame is preliminarily attached before the steel frame is erected, it is possible to attach the fireproof coating material to the main part of the steel frame in advance, but the joint parts of beams and columns, beams and beams, columns and columns, etc. It was impossible to preliminarily put a fireproof coating material on the so-called useless portion such as the periphery thereof. Therefore, in such a case, after the construction is completed, for example, a floor should be laid on the remaining portion after the construction is completed, and scaffolding should be assembled, so that in such a case, The fireproof coating material has to be carried in each time and lifted up to be attached or sprayed, which requires extra work and further lengthens the construction period.

Therefore, an object of the present invention is to solve the above problems in the prior art by providing another fireproof coating material for fireproof coating of a failed portion such as a joint portion of a steel frame such as a beam or a column of a steel frame structure. It is an object of the present invention to provide a steel frame fireproof coating method that can be placed in advance and can be attached so as to fireproof the bad portion such as the joint portion of the steel frame when constructing the steel frame.

[0005]

In order to achieve the above object, according to the present invention, a steel frame fireproof coating method is preliminarily preliminarily attached to a main portion of a steel frame such as a beam or a column of a steel frame structure. For the fireproof covering material, the fireproof covering material for the useless parts such as the joints of steel frames such as beams and columns is attached to the outside of the previous fireproof covering material using a connecting member such as a hinge in advance in a folded state, and the steel frame In the case of erection, the subsequent fire-resistant coating material is attached to the useless portion such as the joint by rotating around the connecting member so as to cover the useless portion.

[0006]

Therefore, according to the present invention, by means of the above-mentioned means, on the fireproof coating material which is preliminarily attached to the main portion of the steel frame such as the beam or column of the steel structure, the useless portion such as the joint portion of the steel frame of the beam or column is provided. Another refractory covering material is placed in advance in a folded state by using a connecting member such as a hinge, and the other refractory covering material is rotated around the connecting member when the steel frame is erected and folded. It can be attached so as to cover the useless part by expanding from to the extended state.

Other objects, features and advantages of the present invention will become apparent from the following detailed description in conjunction with the accompanying drawings.

1 to 10 of the drawings show a fireproof coated steel frame structure manufactured by the steel frame fireproof coating method according to the present invention. For example, the fire-resistant coating materials 2 and 3 are preliminarily attached in advance to both sides and the lower side of the main portion of the steel frame 1 such as a beam or a pillar of a steel frame structure, and then the ends of the fire-resistant coating materials 2 and 3 on both sides and the lower side Further, another refractory covering material 10, 11 for the useless portion 5 such as a joint portion is pivotally attached to both sides and the lower side at one end respectively by a connecting member 12 such as a hinge, and is attached in a folded open state as shown in the drawing. To be These first fireproof coatings 2,
Other refractory coating materials 10 and 11 after 3 are steel sheets 6, 7, 16 and 17 such as zinc-plated steel sheets, colored steel sheets, and vinyl chloride steel sheets, and inorganic fiber materials such as rock wool, glass wool, ceramic fiber, and alumina fiber. Inorganic fiber board, inorganic fiber felt, foam insulation material such as phenol foam, molded board such as calcareous board or gypsum board, fire resistant insulation material 8, 9, 18, 19 which is lined. It is preferable to cut it to a required size in advance so that it can be attached to the periphery of the steel frame 1 in accordance with the size of the steel frame 1 in a factory or to make it into a required shape in advance. Further, although the steel frame 1 is shown as a steel material having an H-shaped cross section, any cross-sectional shape such as square steel and round steel can be used, and the cross-sectional shape of the steel frame is not limited.

In this way, around the steel frame 1 of the steel frame structure,
First, as shown in FIG. 1, two main refractory coating materials 2, 2 are attached to the steel frame 1 in advance from both sides of the steel frame 1, and then another fire resistant coating material 3 is attached from the lower side of the steel frame 1 to the steel frame 1. Attached in advance on the lower side, the fireproof coating material 2 on three sides of the steel frame 1,
3 is attached. In this way, the main fire-resistant coating materials 2 and 3 pre-fabricated in the factory or the like are preliminarily attached to the three sides of the steel frame 1 on both sides and the lower side before being erected. Yet another refractory covering 1 for useless part 5 of
0 and 11 are pivotally attached in advance by a connecting member 12 such as a hinge near the ends of the refractory coverings 2 and 3 and folded outside the refractory coverings 2 and 3 as shown. Can be installed in

Thus, the refractory coverings 10, 11 for the spoiled portion 5 pivotally mounted on the preceding refractory coverings 2, 3 by means of hinge-like connecting members 12 on both sides and underside of the steel frame 1. Is constructed as shown in FIGS. 8 and 9. First, the fireproof coating material 10 for both sides of the steel frame 1 is made so that the steel plate 16 partially overlaps the first fireproof coating material 2 as shown in FIG. A space 20 without the fireproof heat insulating material 18 is provided in the steel sheet 16 and the fireproof heat insulating material 18 is lined on the steel plate 16, and the upper bent portion 21 is bent outward to form the first fireproof coating material 2.
The folds 21 are adapted to be hooked onto the initial refractory covering 2 to aid in support when mounted by means of a connecting member 12 thereon. In addition, the fireproof coating material 11 for the lower side
As shown in FIG. 9, a space 22 without the fireproof heat insulating material is provided so that the steel sheet 17 partially overlaps the steel sheet 7 of the first fireproof coating material 3, and the fireproof heat insulating material 8 of the fireproof coating material 2 on both sides is positioned. Thus, the space portion 23 without the fireproof heat insulating material 19 is opened, and thus the fireproof heat insulating material 19 is lined with the iron plate 17 in a state in which the three sides are opened.

Thus, as shown in FIGS. 1 and 2, before the steel frame 1 is erected, the main fireproof coating materials 2 and 3 are previously attached to both sides and the lower side of the main part of the steel frame 1 in advance. In addition, the refractory covering materials 10 and 11 for the useless portion 5 such as the joint portion are pivotally attached by the connecting member 12 and are preliminarily attached as shown in FIGS. 3 and 4. Next, after constructing the steel frame 1 as shown in FIG. 5 and connecting the joint portion with the joint plate and bolts and nuts, etc., first, the fireproof coating material 10 in the folded state is connected as shown in FIG. It rotates around 12 and coats the dead part 5 so as to be continuous with the fireproof coating material 2, and then the lower fireproof coating material 1
Similarly, 1 is rotated around the connecting member 12 to cover the useless portion 5, the fireproof coating material 11 is temporarily fastened to the fireproof coating material 10 by the fastening member 25 such as a buckle, and later fixed with screws or the like. Then, as shown in FIG. 7, the useless portion 5 of the steel frame 1 is completely fireproof coated.
