Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire-resistant structural wall, and more particularly, to a fire-resistant bulkhead of a pit or fire-block, or a fire-blocking area or a near-fire-blocking area, or the like. The present invention relates to a fire-resistant structure wall constituting an outer wall structure.

[0002]

2. Description of the Related Art A building constructed in a fire protection area or a quasi-fire protection area designated in a city planning area, or a building exceeding a predetermined scale or a predetermined number of floors, is a part which may be spread or spread. Alternatively, the structure constituting the fire compartment or pit compartment must be designed to have a predetermined fire-prevention structure or fire-resistant structure. 2. Description of the Related Art In general, many fireproof or fireproof walls are designed as relatively heavy walls with relatively high specific gravity and high rigidity, such as reinforced concrete structures, PC board structures, ALC board structures, concrete block structures, and the like.

[0003] However, due to the construction period, construction cost or structural restrictions, especially in a residential building or a middle-to-high-rise building in which the wall body must be designed as a lightweight structural wall of a dry construction method, both sides of the steel frame are required. A fire-resistant partition wall of a dry construction method in which a fire-resistant board material is adhered to an outer wall near a boundary of an adjacent land, or a fire-resistant structural wall of a fire prevention section or a pit section is practically adopted in many designs or construction examples. .
For example, pit sections such as elevator shafts, staircases, duct shafts (DS) or piping shafts (PS) in steel structures are often used in many construction cases to connect refractory boards such as gypsum board to mounting hardware, screws and screws. A double-sided board-mounted light iron partition wall fixed to both sides of a lightweight steel base frame with an adhesive or the like, or a fire-resistant and flame-retardant board fixed to the indoor side surface of a steel frame and a steel frame Is designed and constructed in a wall structure such as a fire-resistant bulkhead in which the exposed surface of the pit is coated with a fire-resistant coating material.

[0004] Here, the area inside the pit section, or
The surface to be heated of the fire-resistant wall is hard to tolerate the exposure of the steel material for reasons of fire prevention and fire resistance.Therefore, when constructing a wall such as a pit section, a temporary scaffold is installed in the area inside the pit or outside the building,
Strict refractory coating operations are generally required to coat a steel surface with a predetermined thickness of refractory coating or refractory building material.

[0005]

However, this kind of fire-resistant light iron partition wall is designed to have a specific structure and a dry structure wall structure that is certified or approved to exhibit the desired fire protection performance or fire resistance performance. Therefore, the degree of freedom of design or construction is limited to a considerable extent, and therefore, it must be strictly carried out based on the prescribed method of construction and the details of installation, and as a result, pits Not only is it necessary to install temporary scaffolding etc. in the area within the division or outside of the building, but also the worker is required to strictly install the double-sided board of the fire compartment wall or fire wall in an environment with extremely poor workability or construction efficiency. Construction must be carried out. Such a construction form results in forcing a worker to perform complicated high-altitude work in a limited narrow area or a building dense area, which is not desirable from the viewpoint of safety and health of the construction work.

[0006] By using a fire-resistant wall such as a PC board or an ALC board as a fire protection partition wall in a building or an outer wall of a fire protection area, a fire-resistant coating process of a steel frame can be omitted to some extent. However, this type of construction, in which a heavy-weight wall of this type is carried into a narrow area at a high place or in a densely-built area of a building, and is fixed to the main structure of the building, is adopted by design from the viewpoint of workability and safety. There are difficult circumstances. In addition, in consideration of the safety and workability of building work, for example, for steel frame main structure, etc., reinforced gypsum board, or a special reinforced board having fire resistance performance laminated or stuck in multiple layers, A construction form of constructing a fire compartment wall or a fire wall can be adopted in design. However, this type of wall is generally not provided with an inner frame structure, and is subject to relatively limited restrictions on wall height or wall width from the viewpoint of wall strength or wall rigidity. Absent.

The present invention has been made in view of such circumstances, and an object of the present invention is to eliminate the need for installing temporary scaffolds or the like in a pit section area or a building external area, and to provide a general purpose building. It is an object of the present invention to provide a fire-resistant structural wall in which a board-lining method of a board material for exterior construction is performed from the indoor side so that a fire-resistant partition wall or a fire wall can be constructed relatively easily.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a steel linear member constituting a steel frame, a steel joint or a steel frame of a wall structure. In a fire-resistant structural wall in which a building board material is fixed and constructed as a fire wall or a fire protection partition wall, the steel linear member is made of fire-resistant steel, and the building board material is stretched from the indoor side to the steel linear member. Provided is a fire-resistant structural wall characterized in that it is adapted to be worn.

According to the above configuration of the present invention, the steel linear member is made of fire-resistant steel that can be exposed in the area within the fire protection zone or near the boundary of the adjacent area of the fire protection area. Therefore, it is possible to carry out the board attaching work from the indoor side area without carrying out the work of attaching the building board material from a narrow area such as a fire protection section area or a building dense area. In this specification,
The term refractory steel is used for refractory steel for building structures (FR steel: Fire
Resistant Steel) is used as a concept that includes steel materials coated with fire-resistant paint. In addition, refractory steel for building structures is a steel that has been put into practical use as a result of research and development of structural steel in recent years, and FR steel has a higher temperature range than conventional steel for general structural use. Can exhibit the structural strength of Accordingly, FR steel has recently attracted particular attention as a very advantageous building material for improving the fire resistance of buildings. For example, in a high-temperature atmosphere at a steel material temperature of 600 ° C., at least ／ of normal temperature. By adopting FR steel that can be specified as a steel material that can hold the proof stress, in a structure that can control the steel material temperature at the time of fire not to exceed 600 ° C., the coating thickness of the fireproof coating material is significantly reduced, Or,
The refractory coating itself can be effectively omitted. Further, in the present specification, the fire-resistant paint means a heat-resistant non-foamable paint and a foamable paint that can withstand a high-temperature atmosphere of 600 ° C. or more. The heat-resistant non-foamable paint suppresses the rise in steel material temperature by the heat insulating effect and the action of preventing the diffusion of flammable products, and the foamable paint foams when heated.
A heat resistant film is formed on the surface of the steel material.

A general-purpose gypsum board having a thickness of 30 mm or the like can be appropriately used. Preferably, from the viewpoints of fire prevention and fire resistance and strength, 12.5
gypsum board having a thickness of not less than 1 mm
The gypsum board 11 is preferably a waterproof gypsum board in which the base paper for both sides of the gypsum board and the core material have been subjected to a waterproof treatment in consideration of the influence of weather conditions during construction and the like. . Furthermore, the pit side gypsum board 1
Before inserting one edge into the inserts 48, 58, the adhesive is applied to the edge of the gypsum board 11 or the studs 4, 5,.
6 and the runners 2, 3 are applied to the board contact surfaces. More preferably, a sealing agent is injected or applied in the grooves of the inserts 48, 58, on the board contact surfaces of the studs 6 and the runners 2, 3 and / or on the edges of the gypsum board 11. Insertion part 48, 58, stud 6
Airtight and watertight treatment is performed on the contact portions with the runners 2 and 3. The adhesive or the sealing agent increases the bonding strength between the gypsum board 11 and the studs 4, 5, 6 and the runners 2, 3, and improves the out-of-plane rigidity and impact resistance of the partition wall W. In particular, the sealing agent inserted between the insertion portions 48, 58, the studs 6, and the runners 2, 3 and the edge of the gypsum board 11 not only improves the airtightness and watertightness of the partition wall W. In addition, the sound insulation performance of the partition wall W is improved, and the elastic deformation capability of the sealing agent itself can follow the interlayer displacement of the building while maintaining the desired adhesive strength, which is practically advantageous. As a sealing agent, a modified silicone sealing agent for refractory structures can be preferably used. A suitable modified silicone sealant may be, for example, a bond refractory joint sealant 120 (manufactured by Konishi Co., Ltd.) having a refractory performance for 2 hours. This kind of scouring agent foams and expands under high heat at the time of fire and forms a nonflammable carbonized layer. Thus, it is possible to apply a fire-resistant joint treatment to the wall surface of the pit-side gypsum board 11, which can prevent the flame from entering the room and suppress a rise in the temperature of the heating side surface following the expansion of the joint portion.

The runners 2, 3 thus constructed

It is stuck to the surface of the gypsum board 12. The upper gypsum board 13 is stuck on the lower wall surface in an arbitrary direction and position such as a vertical stretching mode or a horizontal stretching mode, and an interconnecting portion or joint portion of the gypsum board 13 is
The joint is processed by the joint processing material. Upholstered plasterboard 13
For example, any form of gypsum board such as a taper board for a joint method can be suitably used. In general,
After the application of the gypsum board 13, a desired interior finishing material such as a paint or a cloth material is applied to the indoor side board surface by an appropriate application means such as sticking, applying, spraying or bonding.

If desired, a non-combustible heat insulating material such as glass wool or rock wool, or a foamed resin material having self-extinguishing properties may be used for the pit-side plaster board 11 and the indoor-side gypsum board 1.
2 is charged or filled in the hollow layer P formed between the two.
