Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an outer wall panel attached to an outer wall frame of a building.

[Prior Art] As shown in FIG. 7, a conventional outer wall panel attaches a fitting 3 to an outer wall frame (concrete outer wall) 1 of a building, and fixes a body fitting 12 to the fitting 3. The upper edge portion of the lower outer wall panel 13 and the lower edge portion of the upper outer wall panel 13 are attached to the body metal fitting 12 with screws and attached, and the joint material is filled with the sealing material 14.

[Problem to be Solved by the Invention] However, in the above-mentioned conventional outer wall panel 13, the sealing material 14 at the joint portion is deteriorated or peeled off by ultraviolet rays or the like and leaks water, thereby corroding the mounting hardware 3 and the body metal fitting 12 or the like. However, there are problems such as intrusion into the cracked portion of the concrete outer wall 1.

In addition, there is a possibility that rainwater or the like that has accumulated in the horizontal joints may flow down onto the surface of the outer wall panel 13 and become dirty.

The present invention has been made in order to solve the above-mentioned conventional problems. The purpose of the present invention is to omit the filling of the sealing material, eliminate the adverse effect due to the filling, and make the horizontal joint part a gutter structure with rainwater. It is an object of the present invention to provide an outer wall panel that does not have a risk of falling down onto the surface of the outer wall panel and that can reliably and smoothly discharge invading rainwater and the like.

[Means for Solving the Problems] The outer wall panel of the present invention has a downward inclined portion and a rising portion formed at the upper end portion of the panel body, and a downward inclined portion and a hanging portion formed at the lower end portion of the panel body. In the outer wall panel, the rising portion and the hanging portion are oriented in parallel with the panel main body, and the interval between the hanging portion and the panel main body is made smaller than the interval between the rising portion and the panel main body. At the time of attaching, a gap is formed between a rising portion of the lower outer wall panel and a hanging portion of the upper outer wall panel.

Further, an upper inclined portion is further formed on an upper end edge of the rising portion.

Furthermore, a bent portion is formed at both end portions.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes an outer wall skeleton of a reinforced concrete building, in which anchor bolts 2 are appropriately buried, and bracket-like mounting hardware 3 is fastened and fixed thereto.

Reference numeral 4 denotes a metal frame, which is, for example, a long metal formed by extruding a metal such as aluminum, and is mainly formed with a strip-shaped engaging side plate 4a and three guide grooves 4b. They have the same cross-sectional shape in the longitudinal direction. Both ends of the guide groove 4b are open.

The three guide grooves 4b are open outward in a direction in which the adjacent guide grooves 4b are orthogonal to each other, and lips 4c are formed on both sides of the opening entrance portion. .

Therefore, in order to fix the body edge metal fitting 4 to the mounting hardware 3, the head 5 a of the mounting bolt 5 is inserted from the end opening of the guide groove 4 b, and the jaw portion is fixed. The screw portion 5b is made to protrude outward while being locked to the lip 4c, and the screw portion 5b is inserted into the mounting hole of the mounting hardware 3, and tightened and fixed by the nut 5c. At this time, since the mounting bolts 5 are freely slid along the guide grooves 4b, regardless of the mounting pitch of the mounting hardware 3, the mounting bolts 5 have the same length regardless of the length of the rim hardware 4. Regardless, the mounting position can be fixed while arbitrarily adjusting. Accordingly, the metal shell 4 can be cut to any length.

A fitting hole is formed in the end face of the hook side plate 4a, and a round bar projecting from the end face of the other frame fitting 4 is inserted into the fitting hole.
Connect.

Reference numeral 6 denotes a metal outer wall panel. At an upper end portion of the panel body 6 ', a lower inclined portion 6a which is bent inward and downward, and is formed so as to rise upward from a tip of the lower inclined portion 6a. A bent rising portion 6b, and an upper inclined portion 6c bent further inward and upward from the upper end of the rising portion 6b.
Are formed.

The downward inclined portion 6a has a gutter structure so that rainwater or the like that has entered the joint does not flow down to the surface of the outer wall panel 6 and contaminate the panel surface. It is designed to flow to.

A hook 7 for hooking is attached to the back side of the rising portion 6b. The hook 7 is hooked on the hooking side plate 4a of the metal shell 4, and the outer wall panel 6 is temporarily hooked on the metal shell 4. At the same time, the level (height) of the panel is accurately mounted.

The upper inclined portion 6c has a function of discharging rainwater or the like that has entered the inside of the panel to the horizontal joint of the groove structure.

On the other hand, at the lower end of the outer wall panel 6, a downward inclined portion 6d bent inward and downward and a hanging portion 6e bent downward from the tip of the downward inclined portion 6d are formed. ing. The hanging part 6e has a hole for screwing.

The hanging portion 6e is set so as to overlap with the outer side of the rising portion 6b of the outer wall panel 4, and is fixed with screws while being screwed to the hanging side plate 4a with fixing screws 9 with the liner 8 interposed therebetween.

The rising portion 6b and the hanging portion 6e are oriented parallel to the panel body 6 ', and the distance between the hanging portion 6e and the panel body 6' is smaller than the space between the rising portion 6b and the panel body 6 '. Therefore, the liner 8 forms a gap G between the hanging portion 6c and the rising portion 6b. Therefore,
As shown in FIG. 2A, external air can freely flow through the gap G into the inner space of the outer wall panel 4,
There is no evil of the pump action like the conventional closed type,
Because of the drainage effect, the inner space does not become wet and corrosion does not occur.

At both end portions of the outer wall panel 6 are formed bent portions 6f which are bent inward, and as shown in FIG. Since the tip of 6f is slidably abutted on the surface of the vertical grain base plate 10, it not only prevents intrusion of rainwater etc., but also mutually expands and contracts due to thermal expansion etc. of the outer wall panel 6 and the vertical grain base plate 10. It is designed not to be deformed or damaged by excessive force when sliding.

A water return 10a is formed on both sides of the vertical joint base plate 10 so as to embrace the bent portion 6f, and the outer wall panel 6
To prevent water from entering the backside.

Reference numeral 11 denotes a water stop plate, which is attached so as to cover the gap between the upper inclined portions 6c of the left and right outer wall panels 6, as shown in FIG. A cutout portion 11a is formed in the water stop plate 11, and the vertical joint base plate 10 is fitted into the cutout portion 11a, so that the water stop plate 11 can be surely set at an accurate position.

Next, a description will be given of a panel replacement operation such as a case where the outer wall panel 6 is repainted or repaired for damage.

First, the fixing screws 9 at the upper end and the lower end of the outer wall panel 6 to be removed are removed. In this way, even if all the upper and lower fixing screws 9 are removed, the outer wall panel 6 is hung on the hanging side plate 4a of the metal shell 4, so there is no danger of falling.
You don't need to support it by hand.

When the fixing screw 9 at the upper end of the outer wall panel 6 is removed, the lower end of the upper outer wall panel 6 is also removed at the same time. Therefore, following the work of removing the fixing screw 9, as shown in FIG. The lower portion of the panel 6 is pulled out, and the hook 7 for hooking is removed from the hook side plate 4a of the metal shell 4, and the target outer wall panel 6 is removed.

When the outer wall panel 6 that has been repainted or repaired is to be mounted, the above-described procedure of the removal operation may be performed in reverse.

As shown in FIG. 6, the guide groove 4b of the metal shell 4 of the present embodiment is oriented in three directions, and the mounting bolt 5 can be inserted into any of the three directions. In addition, as shown in FIGS. 7 (A) and 7 (B), the outer wall panel can be stuck in any position and direction according to the structure and shape of the outer wall skeleton and the manner in which the outer wall panel is stuck.

The number of the guide grooves is not limited to this.

[Effect of the Invention] Since a gap is formed between the rising portion of the lower outer wall panel and the hanging portion of the upper outer wall panel,
Not only can external air flow freely into the inside space, but also because of the drainage effect, there is no adverse effect of the pumping action as in the conventional closed type, and the inside space becomes wet and corrosion occurs There is no fear of doing.
