Problems solved by technology

In the design in which the surface of the wood of these wooden beams and columns is exposed to the interior, the desired fire resistance can be obtained by performing fire-resistant design (Japanese: 火え代设计), but in such a When fire-designed beams and columns form penetrations, fire resistance will be lost at the penetrations, and the fire will spread from the penetrations to the surrounding areas. impact on the supporting force

Embodiment Construction

[0024] Such as figure 1 and figure 2 As shown, the fire-resistant cladding material 10 for a penetration portion according to a preferred embodiment of the present invention is used for the purpose of forming, for example, a passage for piping and wiring in a fire-resistant beam 20 as a fire-resistant structural member of a wooden building. When the penetration portion 11 is formed, by carrying out refractory coating on the inner peripheral surface of the penetration portion 11, it can effectively avoid losing the fire resistance of the fire-resistant beam 20 in the portion of the penetration portion 11 and affecting the supporting force of the load-bearing layer of the fire-resistant beam 20. . The fire-resistant coating material 10 for the penetration portion of the present embodiment is preferably formed simply, accurately, and inexpensively using a commercially available gypsum board, and has a function of enabling simple and low-cost fire-resistant coating of the penet...

Abstract

Provided is a penetration part fireproof coating material (10) used when a fireproof coated penetration part (11) is provided to a fireproof beam (20) which is a fireproof structural member constituting a wooden building. The penetration part fireproof coating material is cylindrically formed when a plurality of gypsum board pieces (13a) formed from a gypsum board (13) are integrally joined to each other in a state of being laminated in the thickness direction. When a plurality of preferably annular gypsum board pieces (13a), which are cut off from the commercially available gypsum board 13 that has a thickness of 9.5-25.5 mm, are fixed to each other by use of a metal fastener such as a staple (14) preferably, the penetration part fireproof coating material (10) is cylindrically formed bythe gypsum board pieces being integrally joined to each other in a state of being laminated in the thickness direction.

Description

technical field [0001] The present invention relates to a fire-resistant coating material for a penetration portion, and more particularly, to a fire-resistant coating material for a penetration portion used when a through-hole covered with fire-resistant coating is provided in a wooden building. Background technique [0002] When a fire occurs inside a wooden building, in order to limit the fire to a certain range and prevent it from spreading to other places, it is preferable to install a fire compartment. A fire compartment is a compartment that divides a building into several parts by using fire-resistant floors, walls, ceilings, fire doors, etc. It is surrounded and formed by equal wall bodies (hereinafter referred to as "fire compartment body"). In addition, it is sometimes necessary to provide penetrations for piping, wiring, etc. in the surrounding fire compartments. As a structure for forming penetrations in the fire compartments, for example, Figure 6 of (a), Fi...
