Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a box panel used for exterior of a building or the like, and a mounting structure thereof.

[Conventional technology]

This type of box panel is made by pressing a steel plate into a rectangular shallow box shape, and extending the mounting flanges from the four side walls. As shown in Fig. 9, the outer surface of the structure has a grid pattern. The flanges 1a and 1b of the adjacent box panel 1 are overlaid on the outer surface of the base material 2 such as the assembled angle material, and the tapping screws 5 are tightened together to connect the panels 1 and 1.
The groove-like joint 3 formed between them was filled with the backup material 6 and the caulking material 7. See, for example, Japanese Utility Model Laid-Open No. 60-46711 and Japanese Patent Publication No. 62-166937.

[Problems to be solved by the device]

In such a conventional box panel and its mounting structure, when rainwater penetrates into the joint 3 due to deterioration of the caulking material 7, the flanges 1a and 1b are bonded to each other directly or through a seal material (packing material) in a close contact manner. There is no place for water to escape. Therefore, backup material 6
The rainwater that had soaked into the water was likely to stay for a long time as it was, and this made it easy for corrosion to occur in the screw-fastened portion where the coating was interrupted and in the screw 5. Such corrosion can lead to box panel detachment from the structure.

Yet another conventional example is Japanese Utility Model Laid-Open No. 59-157051, which will be described with reference to the accompanying drawings for explaining the present invention. The four side peripheral walls (1A to 1A) of a box panel 1 formed in a rectangular box shape. The mounting flanges (1a to 1d) extend outwardly from 1D). Of these four side peripheral walls (1A to 1D), the lower peripheral wall 1B on the lower side and one of the left and right first side peripheral walls 1C
Is the upper peripheral wall 1A on the upper side and the other left and right second side peripheral walls.
Dimension lower than 1D. Thus, as shown in FIGS. 5 and 6, when the box panels 1 are arranged vertically and horizontally, the upper and lower flanges 1a and 1b and the left and right flanges 1c are arranged.
It is known to provide a ventilation gap with 1d. There, a packing material (corresponding to the spacer 4 of the present invention) is interposed in a lateral joint 3 corresponding to FIG. There is.

However, also in the above-mentioned conventional example, when the joint 3 in the vertical direction corresponding to FIG. 6 of the present invention is viewed, the left and right flanges 1c and 1d are in close contact with each other via the seal member.
Therefore, in this respect, the problem due to the infiltration of rainwater due to the deterioration of the seal member has not been solved yet. Also, in the horizontal and vertical joints 3, it is necessary to prevent rainwater from entering the inside of the structure.
Intrusion is prevented by interposing a separate member, and this point is also a top-down of construction.

Further, when the box panels 1 are mounted side by side in the vertical and horizontal directions, rainwater flows through the joints 3, particularly in the vertical direction. Therefore, the point at the corner of each box panel 1 must be cleaned up. This point is ignored.

Therefore, the purpose of the present invention is to provide an exterior box panel that can easily and easily prevent rainwater from entering the inside of the building section, regardless of whether the rainwater enters the interior of the joint vertically or horizontally. And its mounting structure.

An object of the present invention is to make it possible to achieve a perfect rain finish when the box panels are mounted side by side vertically and horizontally.

[Means for solving the problem]

The box panel according to the present invention is formed in a rectangular box shape as shown in FIG. 1, and the mounting flanges 1a to 1d extend outward from the peripheral walls 1A to 1D of the four sides, and the peripheral walls of the four sides. Of 1A-1D, lower peripheral wall 1B on the lower side
And the left or right first side peripheral wall 1C is the upper peripheral wall 1A on the upper side.
And the dimensions are set lower than the other left and right second side peripheral walls 1D.

The rising pieces 1e and 1f are formed on the outer edges of the flanges 1a and 1d of the upper peripheral wall 1A and the second side peripheral wall 1D so as to stand outward, and these upper peripheral wall 1A and the second side peripheral wall 1D are formed. Spacers 4 that receive the flanges 1b and 1c of the lower peripheral wall 1B and the first side peripheral wall 1C of the adjacent panel are integrally attached to the flanges 1a and 1d at appropriate positions on the outward surface.

Flange 1a and 1d of upper peripheral wall 1A and second side peripheral wall 1D
Is continuous at the corner portion 1g, and a tongue piece 1h is extended upward from the corner portion 1g.

Thus, as shown in FIGS. 5 and 6, each box panel 1 is fastened to the outer surface of the structure through its flanges 1a to 1d, and between the adjacent panels,
As shown in the drawing, the tongue piece 1h is joined inside and outside so as to wrap around to the back surface side of the lower end portion of the flange 1d of the second side peripheral wall 1D of the box panel 1 located above, and is formed between adjacent panels. The joints 3 in the vertical and horizontal directions are filled with caulking material 7 and attached.

[Action]

The box panel 1 is fixed to the outer surface of the structure through the flanges 1a to 1d so that the joints 3 run vertically and horizontally. At this time, the box panels 1.1 adjacent to each other vertically,
As shown in FIG. 5, in the lateral joint 3 between the two,
The flange 1b of the lower peripheral wall 1B of the upper panel 1 is received outside the flange 1a of the upper peripheral wall 1A of the lower panel 1 via the spacer 4, and the rainwater that has infiltrated into the joint 3 is guided between the flanges 1a and 1b. A trough-shaped passage is formed along the inner depth of the joint 3, and the rising piece 1e provided on the flange 1a of the upper peripheral wall 1A prevents rainwater from flowing into the back side of the structure.

Further, as shown in FIG. 6, the box panels 1, 1 adjacent to each other on the left and right have a spacer 4 on the outer side of the flange 1d of one of the left and right second side peripheral walls 1D at the joint 3 in the vertical direction between them. The flange 1c of the other left and right first side peripheral wall 1C is received, and the joint 3 is formed between the flanges 1c and 1d.
A trough-shaped passage for guiding rainwater that has invaded inside is formed vertically along the inner depth of the joint 3, and the rainwater is provided on the rear surface of the building by the rising piece 1f provided on the flange 1d of the second side peripheral wall 1D. It is blocked from flowing into the side.

The rising pieces 1e and 1f have a function of preventing rainwater from flowing into the inside of the structure at joints and reinforcing the flanges 1a and 1d provided with the rainwater.

When the box panel 1 is mounted vertically and horizontally, how to prevent rainwater from entering the back side of the structure at joints 3 of adjacent corners becomes a problem. In this respect, in the present invention, the flanges 1a and 1d of the upper peripheral wall 1A and the second side peripheral wall 1D are continuous at the corner portion 1g, and the tongue piece 1h is extended upward from the corner portion 1g. In the attached state 1, the tongue piece 1h of the lower panel 1 goes around to the rear surface side of the lower end portion of the flange 1d of the second side peripheral wall 1D of the upper panel 1 and is joined inside and outside. Therefore, rainwater does not enter the inside of the structure at the corners of the box panels 1.

[Effect of device]

Therefore, according to the box panel of the present invention, even if rainwater penetrates deeply into the joint 3 due to the deterioration of the caulking material 7, it does not stay inside for a long time and prevents the screwed portion from corroding early. The durability can be improved.

By arranging the spacer 4, the inner and outer widths of the peripheral wall of the flange mounted on and connected to the spacer 4 are reduced,
The substantial depth of the joint 3 becomes shallower than the thickness of the panel, and the filling amount of the caulking material 7 can be reduced only by that, and the construction can be speeded up by shortening the caulking processing time.

Furthermore, the rainwater that has infiltrated into the joints 3 is the start-up piece 1e provided on the flanges 1a and 1d of the upper peripheral wall 1A and the second side peripheral wall 1D.
In 1f, it does not flow into the back side of the structure. Since the rising pieces 1e and 1f also reinforce the flanges 1a and 1d, the vertical and horizontal joints 3 are properly exposed, and the box panel 1 can be securely and easily attached to the structure.

Since the spacer 4 is integrally attached to the upper peripheral wall 1A and the second side peripheral wall 1D, the box panel 1 on site
It can be done easily and securely.

Further, due to the presence of the tongue piece 1h, rainwater can be prevented from wrapping around to the back side of the structure at the corners of the adjacent panels 1, especially at the joints 3 in the vertical direction, and also in this respect, the rain finish can be perfected. .

〔Example〕

In Fig. 1 and Fig. 2, the box panel 1 is made by press-forming a steel plate into a shallow square box shape and is coated with it. The upper, lower, left and right peripheral walls 1A, 1B, 1C, 1D are attached to the mounting flange 1a.・ 1b, 1c, and 1d are extended to the outside and are connected in series.

As shown in FIG. 3, each box panel 1 is screwed while forming joints 3 of an appropriate width along a base material 2 assembled in a grid pattern on the outer surface of the structure.

Of the peripheral walls 1A to D, the inner and outer widths of the lower peripheral wall 1B corresponding to the lower side in FIG. 1 and the first side peripheral wall 1C adjacent to the left side thereof are the same as the upper peripheral wall 1A corresponding to the upper side and the right side adjacent to the upper peripheral wall 1A. The size is set smaller than the inner and outer widths of the two side peripheral walls 1D.
Also, each flange 1a of the upper peripheral wall 1A and the second side peripheral wall 1D
The overhang amount of 1d is set to be approximately the same as the maximum joint width, and each flange 1b of the lower peripheral wall 1B and the first side peripheral wall 1C
The overhang amount of 1c is set smaller than the joint width.

Further, at a plurality of suitable places (three in the figure) on the outward surface of the wide flanges 1a and 1d located on the upper side and the right side,
Spacers 4 formed by bending a steel plate are integrally attached by spot welding or an adhesive. The spacer 4 is the fifth
As shown in FIGS. 7 to 7, the protruding height is defined so that the outer surfaces of all the panels are flush with each other while receiving the lower flange 1b and the right flange 1c of another panel adjacent to the upper side and the right side. .

When assembling the panel, the lower flange 1b and the left flange 1c of the box panel 1 are placed on the spacers 4 of the upper flange 1a and the right flange 1d of the adjacent panel 1 which is previously attached, and then the tapping screw 5 or the self-drilling Each panel 1 is fixed to the base material 2 by passing screws and the like through the spacers 4 to the base material 2 and fastening them. As a result, joints 3 having a desired width are formed between the adjacent panels 1 and 1, and the joints 3 are filled with the backup material 6 and the caulking material 7 in order from the outside for waterproofing.

From the edges of the upper side flange 1a and the right side flange 1d, rising pieces 1e and 1f are provided so as to be folded back outward so that the flanges (1a located inside and outside the adjacent panels 1 and 1) are
And 1b, and 1c and 1d), a gutter-shaped passage for guiding rainwater that has entered the joint 3 is formed vertically and horizontally along the inner depth of the joint 3.

The upper side flange 1a and the right side flange 1d are continuous at a corner 1g as shown in FIG.
The tongue piece 1h is extended upward from 1g to prevent vertical running water from flowing out to the back side (base material side). That is, as shown in FIG. 4 and FIG. 7, the upper end portion (tongue piece 1h) of the right side flange 1d of one panel 1 is on the rear surface side of the lower end portion of the right side flange 1d of the adjacent panel 1 located above this. It goes around and wraps inside and outside to join.

[Another embodiment example]

In the above embodiment, the adjacent box panels 1.1 are attached to the base material 2 only by the screws 5 penetrating the flanges (1a-1b.1d-1c) and the spacer 4, but the flanges 1a. After first screwing it to the base material 2 at a position deviated from 4, the flange 1b of another panel 1
The specification may be such that 1c is screwed to the base material 2 via the spacer 4. In this case, the flange of another panel 1
The spacers 1b and 1c may be screwed only to the spacer 4 and penetrated into the base material 2 without being fixed. Further, the panel 1 and the base material 2, and the spacer 4 and the flange may be fixed to each other by welding or the like. Although the base material 2 in the drawing is a frame having an L-shaped cross section, the flange may be fixed to a metal fitting or the like fixed to the frame.

The spacer 4 is, for example, a start-up piece 1e
It may be formed by bending a part of 1f to the outer surface side of the flanges 1a and 1d, and is not necessarily limited to the specification of being formed separately from the box panel 1 and attached later.
