JPH08144469A - Fitting structure of projected corner of external wall - Google Patents

Abstract

PURPOSE: To provide a fitting structure of the projected corner of an external wall in which accessories at the projected corner can be safely and easily fixed without exposed fixing nails and hence a neat external appearance can be obtained. CONSTITUTION: Accessories 2 at projected corners having a L-shaped section are applied on the external face of a column 1. The hooked part 3A of the front end of a fixing metal tool 3 nailed at the external face of column 1 at the base 3B thereof, is fixed at the fixing step 2A installed in the side end of accessories. The accessories 2 at the projected corner are fixed to the side face of column 1 through the fixing metal tool 3. The external wall plates 4 are arranged to butt against the side end of the fixed accessories 2 and a sealing agent 6 is charged to cover the hooked part 3A of fixing metal tool 3 in the clearance 5 between joints of the accessories and the external wall plate 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for an outer wall protruding corner portion, and more particularly to an improvement of an outer wall protruding corner mounting structure constructed by using an outer wall plate.

[0002]

2. Description of the Related Art Conventionally, as an outer wall structure of a building, a so-called dry outer wall structure in which an outer wall plate made of fiber reinforced cement plate or the like is attached to a wall base material is known. By the way, in the case of these dry outer wall structures, at the projected corners of the outer wall, the end portions of the outer wall plates are abutted against each other, and the appearance is very poor and the waterproofness is not sufficient, as it is.
Normally, as shown in FIG. 5, a projected corner accessory A is used, the projected corner accessory A is nailed to a corner post C, and the outer wall boards B, B are connected to the side ends of the projected corner accessory A. By doing so, the appearance is adjusted and the waterproof property is improved. In order to eliminate discomfort with the outer wall board B, the outer corner board A is made of fiber reinforced cement when the outer wall board is a fiber reinforced cement board, for example.

[0003]

[Problems of the Prior Art] When the projected corner accessory A is made of fiber reinforced cement as described above, the material is hard and brittle, so that it may crack if the driving force at the time of nailing is large. There is also a structure in which outer wall plates are laminated at right angles as a projecting corner product, and in this case there is a problem that the laminated part may peel off due to the impact when nailing, so it is necessary to be extremely careful when installing. However, there was a problem that construction was not easy. In addition, after nailing and fixing, since the nail heads D are exposed at points along the side edge of the projected corner accessory, the external appearance of the projected corner becomes complicated, and there is also a drawback that the appearance is not neat.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems and has a neat appearance in which the protruding corner accessory can be fixed safely and easily, and the fastening nails are not exposed. The purpose of the present invention is to provide a mounting structure for the outer corner of the outer wall.

[0005]

That is, in the mounting structure for the outer wall projecting corner portion of the present invention, a projecting corner accessory 2 having an L-shaped cross section is applied to the outer surface of the projecting corner of the pillar 1, and the projecting corner part is provided. An engaging step portion 2A provided at a side end portion of the accessory 2 has a key-like engaging portion 3A at a tip thereof, and a base portion 3B is fixed to the outer surface of the pillar 1 by a nail 3.
The key-shaped portion 3A is engaged, the projected corner accessory 2 is fixed to the side surface of the pillar 1 through the fastener 3, and the outer wall plate 4 projects to the side end portion of the fixed projected corner accessory 2. It is characterized in that the sealant 6 is filled in the joint gap 5 between the projected corner accessory 2 and the outer wall plate 4 so as to cover the key-like engaging portion 3A of the fastener 3.

[0006]

In the mounting structure of the outer corner projecting portion of the present invention, when mounting the projecting corner accessory 2 to the pillar 1, the fixing metal fitting 3 nailed to the pillar 1 instead of directly driving the nail into the projecting corner accessory 2. Since it is fixed via the key-like engaging portion 3A, there is no possibility of damaging the projected corner accessory 2. Further, the key-like engaging portion 3A of the stopper 3
Is not exposed to the outside because it is covered with the sealant 6.

[0007]

Embodiments of the present invention will be described below. FIG. 1 is a perspective view of an embodiment of the present invention, FIG. 2 is an enlarged transverse sectional view of an essential part of the embodiment, FIG. 3 is an enlarged vertical sectional view of an essential part of the embodiment, and FIG. 4 is a perspective view of a stopper.

The outer wall projecting corner mounting structure of the present invention has a cross section L on the projecting corner outer surface of the pillar 1 provided at the corner of the building.
A character-shaped projecting corner accessory 2 is applied, and an engaging step portion 2A provided at a side end portion of the projecting corner accessory 2 has a key-like engaging portion 3A at its tip and the base portion 3B is the above-mentioned. The key-shaped portion 3A of the fastener 3 fixed to the outer surface of the pillar 1 by the nail is engaged, and the projected corner accessory 2
Is fixed to the side surface of the pillar 1 through a stopper 3, and an outer wall plate 4 is abutted on the side end portion of the fixed protruding corner accessory 2 to form a joint gap 5 between the protruding corner accessory 2 and the outer wall board 4. To the stopper 3
The sealant 6 is filled so as to cover the key-like engaging portion 3A.

Reference numeral 7 in the drawing denotes a waterproof sheet arranged on the lower ground of the projected corner accessory 2 and the outer wall plate 4. In the above,
When the outer wall board 4 is a fiber reinforced cement board,
It is made of fiber reinforced cement of the same material. Further, the projected corner accessory 2 may be integrally molded in an L-shaped cross section, or may be formed by abutting the strip sides of the outer wall plate 4 at a right angle and adhering and pasting at a right angle portion. As shown in FIG. 3, the lower end of the projected corner accessory 2 is fixedly supported by a lower end support fitting 8.

As shown in FIG. 4 (a), the fastener 3 is a molded body in which the key-like engaging portion 3A is erected on the base portion 3B, and as shown in FIG. The board 3B is provided with a cut 3C and the key-like engaging portion 3A is bent, or
As shown in (C), one substrate 3B may be bent in a stepwise manner and one end thereof may be used as the key-like engaging portion 3A.

[0011]

As described above, according to the outer wall projecting corner mounting structure of the present invention, the projecting corner member formed in the L-shaped cross section can be mounted without fear of being damaged at all, and moreover, it can be mounted. Since the stopper for fixing the corner material is covered by the joining step portion of the outer wall plate for joining, the appearance of the outer wall protruding corner portion also has a neat appearance. Therefore, there is an effect that the outer wall protruding corner can be attached and installed very easily.
