Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a fireproof joint structure of a wall formed by using a panel.

[Conventional technology]

In general, when a panel is used to form a wall, for example, a horizontal or vertical stretched inner or outer wall, the joint of the panel ends, the so-called joint structure is fireproof, waterproof, external appearance, and also in terms of construction. It was a big neck.

[Problems to be solved by the device]

That is, in the case of a fire, there is usually a drawback that only one iron plate is present in the joint portion and the wall foundations such as studs and furring strips burn. In addition, in terms of waterproofing, there was a disadvantage that rainwater leaked to the back surface of the wall from the nail head and the abutting portion of the panel. Further, Jikkou 54-26647 is known as an improved joint of this kind. However, with this structure, not only is it difficult to process the clip, but there is too much waste of material, and there are no waterproof tongues at both longitudinal ends of the belt-like seat plate, and there is leakage of rainwater to the back surface of the wall. . Since the pawl claws have a shape that is easily elastically deformed, the band-shaped cover is easily removed.
Since a large gap is required between the ends of the outer wall plate, especially a gap in which the palm-growing claw can be deformed, the heat insulation of the joint is poor. It is necessary to process the edges of the exterior plate. There were drawbacks such as.

[Means for Solving the Problems]

In order to eliminate such drawbacks, the present invention uses, for example, a locking body in which one plate is formed in a substantially T-shaped cross section, a cover provided with locking tongues, and the wall base material described above. We propose a fireproof joint structure of a wall, which is composed of a fireproof inorganic sheet provided between the body and a long panel, and has greatly improved heat insulation and fireproofness.

[Constitution of device]

Hereinafter, one embodiment of a wall fireproof joint structure (hereinafter, simply referred to as joint) according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a vertical cross-sectional view showing the above purpose, 1 is a locking body, 5 is a cover, 11 is a fireproof inorganic sheet, 12 is a panel, α is a wall base material such as a stud, β is a fixture, γ Is a caulking material. To further explain, as shown in FIG. 2 (a), the locking body 1 is made of a long body, for example, a metal plate, a synthetic resin plate, or a combination thereof, and is roll-formed,
By bending, pressing, extruding, drawing, injection molding, or a combination of these, a vertical T-shaped cross section is formed, and it is mainly attached to waterproof base materials, isolation walls, guides, and furring strips. It serves as a portion, a pressure fixing portion having a width wider than the joint width of the fireproof inorganic sheet 11, which will be described later, and a locking portion. That is, the locking body 1 is composed of a horizontal plane portion 3 projecting along the longitudinal direction at the central portion with respect to the short direction of the surface 2a of the long vertical plane portion 2 and a vertical plane portion 2 above the horizontal plane portion 3. It is formed from an upper horizontal surface 3a formed by an obtuse angle close to a right angle, that is, a so-called slightly inclined surface, and a lower horizontal surface 3b formed at a lower portion of the horizontal surface portion 3 at an angle perpendicular to the vertical surface portion 2. The fitting portion 4 at the tip of the horizontal surface portion 3 has a dovetail groove shape such as an isosceles shape, an isosceles trapezoidal shape, a rhombus, a square, a square, a semicircle, and an ellipse in cross section.
Any shape may be used as long as the cover 5 to be described later is fitted and then locked so as not to be separated from external force. Further, the cover 5 is a long member having elasticity as shown in FIG. 2B, for example, a metal plate (color steel plate, PVC steel plate, aluminum plate, stainless plate, copper plate, etc.), synthetic resin plate, etc.
Similar to 1 , roll forming, bending, pressing, extrusion, drawing, injection molding, or a combination of these forms an L-shaped cross section, and the upper end of the short decorative surface 6 is approximately right angle inward.

To explain further, the cover 5 is mainly composed of the joint portion 13, the end portion of the panel 12 forming the joint portion 13, and the head of the fixing tool β struck on the end portion of the panel 12 by brain strike or the like. The part particularly located on the lower side is covered after mounting the panel, and functions as a decorative surface and a waterproof surface. The fireproof inorganic sheet 11 is made of rock wool, glass wool,
Ceramic wool, carbon fiber felts, foamed gypsum sheets (product name KG sheet), or sheet-like materials obtained by adding a fireproofing agent to these sheets and having a thickness of about 1 to 10 mm.

Next, a construction example will be briefly described with reference to FIG. 1. A plurality of fireproof inorganic sheets 11 are provided on a wall base material α such as a stud and a pitch corresponding to the length of the panel 12, a so-called joint portion 13. The joint portion 13 is arranged in a wide width at a substantially central position, and at the same position, a plurality of locking bodies 1 are laid at each pitch so as to cover the fireproof inorganic sheet 11, and a vertical surface portion thereof is provided. 2 is fixed via a fixing tool β such as a nail. Next, the end of each panel 12 is placed on the surface 2a of the vertical surface 2 to cover it, and the end of each panel 12 is contacted with the upper horizontal plane 3a and the lower horizontal plane 3b. And fix the panel 12. After that, the cover 5 is fitted into the fitting insertion portion 4 so that the insertion piece 7 is located above the cover 5, and the joint portion 13

[Effect of device]

As described above, in the fireproof joint structure of the wall according to the present invention,
Since the upper horizontal surface and the insert piece are slightly inclined, the draining effect is improved. Further, since the iron plate and the fireproof inorganic sheet are arranged wider than the joint width on both the upper and lower back surfaces of the joint, which is the weakest point in fire prevention, the fireproof performance is greatly improved. Since the horizontal surface of the locking body can be used as a guide during panel construction, there is no need to pay attention to the joint spacing, and there is a feature of excellent workability. Further, since the locking body and the cover have a simple structure, there is an advantage that they can be manufactured at low cost.
