Description

  The present invention relates to an outer wall construction structure in which a plurality of outer wall plates are constructed while being joined up and down and constructed to construct an outer wall.

Conventionally, as shown in FIG. 5, the upper lower solid portion 91 provided on the upper side of the outer wall plate 90 is overlapped with the lower upper solid portion 92 provided on the lower side of the outer wall plate 90 so that the plurality of outer wall plates 90 are vertically moved. There is an outer wall construction structure 9 formed by joining and constructing.
In the outer wall construction structure 9, the lower end corner portion 921 at the lower end of the design surface 900 of the upper outer wall plate 90 and the joint joint portion 93 formed at the upper end of the design surface 900 of the lower outer wall plate 90 are front and rear. The upper lower solid portion 91 and the lower upper solid portion 92 are joined so as to coincide with each other in position.

  However, as shown in FIG. 6, the upper outer wall plate 90 protrudes too much forward with respect to the lower outer wall plate 90 due to unevenness of the outer wall base surface, construction error, or dimensional error of the outer wall plate 90, and the like. The corner portion 921 may protrude forward from the joint portion 93. Accordingly, when a step S is generated between the lower end corner portion 921 and the joint joint portion 93, the shadow of the lower end corner portion 921 is reflected on the joint joint portion 93 due to sunlight L from obliquely above. And the shadow is continuously formed over the left-right direction of an outer wall surface, and the external appearance of the design surface 900 may be parted and the beauty | look may be impaired.

Further, as a means for preventing shadows from being formed at the joint portions of the upper and lower wall plates, a wall plate joint structure in which a chamfered portion is provided at the lower end portion of the surface has been proposed (see Patent Document 1).
However, the wallboard construction structure of the above-mentioned patent document 1 is intended for an outer wall having a seamless large wall finish. For this reason, slight deviations are easily noticeable, and the inclination of the chamfered portion cannot be increased. Therefore, only a slight shift is assumed as the shift before and after the wallboard.
Accordingly, it is difficult to sufficiently cope with unevenness of the outer wall base surface, construction error, dimensional error of the outer wall plate, and the like when the outer wall is constructed.

  This invention is made | formed in view of this conventional problem, and intends to provide the outer wall construction structure excellent in the external appearance design property.

The present invention is an outer wall construction structure in which an outer wall is constructed by joining an outer wall plate having an upper lower solid part provided on the upper side and a lower upper solid part provided on the lower side while joining together a plurality of sheets. There,
The outer wall plate has a horizontal joint part and a convex part formed between the horizontal joint part on the design surface,
The lower end portion of the design surface is provided with a lower end inclined portion inclined backward, and the upper end of the design surface is provided with a joint joint portion that is recessed from the convex portion,
In the two outer wall plates joined together in the vertical direction, the lower end inclined portion of the upper outer wall plate and the joint joint portion of the lower outer wall plate are arranged adjacent to each other in the vertical direction, and the joint joint The front end of the part is arranged to protrude forward from the lower end of the lower inclined part,
The joint joint portion includes a joint slope portion inclined backward as it goes downward from the front end portion, and a joint flat portion formed in a vertical direction from a lower end of the joint slope portion. It is in the construction structure (Claim 1).

Next, the effects of the present invention will be described.
In the outer wall construction structure, the lower end inclined portion inclined rearward is formed at the lower end portion of the design surface of the outer wall plate. Therefore, the shadow of the lower upper solid part of the upper outer wall plate can be prevented from being formed on the joint joint.
In addition, the front end portion of the joint joint portion in the lower outer wall plate projects forward from the lower end portion of the lower end inclined portion in the upper outer wall plate. Therefore, it is possible to prevent the shadow of the lower upper solid part of the upper outer wall plate from being formed in the joint part.

That is, the lower side of the upper outer wall plate may be shifted forward or the upper side of the lower outer wall plate may be shifted backward due to unevenness of the ground surface of the outer wall, construction error, or dimensional error of the outer wall plate. If the front end portion of the joint joint portion is located in front of the lower end portion of the lower end inclined portion, the shadow of the lower upper solid portion of the upper outer wall plate is not formed on the joint joint portion.
And a design surface can be continuously expressed in the whole outer wall, without dividing a design surface linearly in the said joint part. As a result, it is possible to obtain an outer wall construction structure excellent in appearance design.

Moreover, the said joint part has the joint inclination part inclined toward the back as it goes below from the said front-end part, and the joint flat part formed toward the perpendicular direction from the lower end of this joint inclination part.

Is arranged. As shown in FIG. 2, the depth D of the horizontal joint portion 2 is from the most forwardly projecting portion of the convex portion 101 of the outer wall plate 10 disposed adjacent to the top and bottom to the bottom line A of the horizontal joint portion 2. The distance before and after.

  Further, as shown in FIG. 1, the amount of forward projection a of the front end portion 130 of the joint joint 13 with respect to the lower end portion 121 of the lower end inclined portion 120, and the joint flatness of the joint joint 13 with respect to the lower end portion 121 of the lower end inclined portion 120. The amount of forward protrusion b of the portion 133 has a relationship of 0.3a ≦ b ≦ 0.9a.

Moreover, the joint inclination part 132 has an angle of 5-30 degrees with respect to the perpendicular direction.
