Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the exterior structure of architectural structures.

[Prior art and problems to be solved] Conventionally, in an exterior structure in which a plurality of exterior panels are successively installed horizontally along the outer surface of a building, for example, the present applicant has filed an application dated August 10, 1980. As shown in the example of "Fireproof Exterior Structure of Building Structures" (Japanese Patent Application No. 59-166489), exterior boards are applied to the pillars or studs of the building, and these are fixed with fixing devices such as nails or stainless steel screws. I was trying to do that.

However, with this type of exterior structure, even if strings or steel wires are stretched to level the exterior panels with respect to the building (positioning the exterior panels horizontally), there is no guideline for this, making work difficult. When fixing an exterior plate to a manufactured column, it is necessary to drill a hole in the column and fix it with screws, so the construction work takes a long time. Furthermore, since a large number of fixing devices are used, the overall cost tends to be high, especially when expensive stainless steel screws are used as the fixing devices.

The present invention has been made to solve these conventional problems, that is, to improve workability for attaching exterior panels, shorten construction time, and further reduce costs.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention includes long metal mounting members that are mounted vertically along the outer surface of a building at appropriate intervals from each other; It has a board-roofed exterior structure including a plurality of exterior plates that are sequentially fixed to the outside of the attachment member in the longitudinal direction of the attachment member. Further, the lower end of the exterior plate is folded inward to form a fitting portion having a substantially inverted U-shaped cross section into which the upper end of another exterior plate adjacent to the lower end is fitted, and the mounting member is provided with a fitting portion of the exterior plate. A hook-shaped claw bent downward corresponding to the shape of the upper edge of the mating part,
A flat claw located below the hook-shaped claw and protruding in a substantially horizontal direction by a distance corresponding to the vertical dimension of the fitting portion is cut and raised outward, and an exterior is provided between the hook-shaped claw and the flat claw. The exterior plate is fixed to the mounting member by deforming the flat claw toward the hook-shaped claw while holding the plate fitting portion.

[Function] The present invention is constructed as described above, and has a structure in which a plurality of horizontally roofed exterior panels are connected and engaged with the lower exterior panels at the fitting portions formed at the lower ends thereof. For this reason, a strong outer wall can be constructed by simply providing a small number of fixing points to the long metal mounting member. The exterior plate can be fixed to the mounting member by simply deforming the flat claw at the lower end while holding the fitting portion of the exterior plate between the two. The work to deform the flat claws is simply a simple caulking operation, for example, by hitting the flat claws from slightly below with a hammer, so it is necessary to drill screw holes in the mounting post and attach the exterior plate with screws as in the conventional method. It is significantly easier to work than the process of tightening, and requires less time for construction. Also,
Since no nails or screws are required for fixing, the exterior structure is inexpensive.

On the other hand, regarding the leveling work, the positioning of the exterior plate relative to the mounting member is automatically done using the hook-shaped claws and flat claws, so it is not necessary, and the longitudinal positioning of the mounting member is done using the hook-shaped claws or flat claws as clues. This can be done relatively easily since strings or steel wires can be stretched. Therefore, in the present invention, construction workability and work efficiency are improved also in terms of leveling work.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 5.

In Figure 1 or Figure 2, 11 is a horizontally constructed C
A long member made of shaped steel; 12 is the long member 11;
elongated metal mounting members 20 fixed perpendicularly to each other via fixing devices 13 such as screws;
is a pair of claws 1 to be described later on the mounting member 12.
This is an exterior board that is horizontally roofed through 4 and 15.

The mounting member 12 has a shape in which flanges 12b are protruded from both sides of a groove 12a whose cross section is open to the outside. A plurality of pieces are fixed at appropriate intervals. Further, as shown in FIG. 3, the flanges 12b on both sides are provided with a hook-shaped claw 14 bent downward from the middle and a flat claw 15 projecting horizontally at a predetermined interval (described later). The pair of claws 14 and 15 are provided at a plurality of locations at intervals corresponding to the width of the exterior plate 20 in the vertical direction.

On the other hand, the exterior plate 20 is made of an integrally bent product such as aluminum, painted steel plate, or flame-retardant synthetic resin plate, and is fitted into the upper edge of the flat plate part 21 as shown in FIGS. 4 and 6. The fitting portions 23 are formed on the lower edges of the portions 22 so as to be located closer to the indoor side than the flat plate portions 21, respectively. That is, the fitting part 22 is provided on the upper edge of the flat plate part 21 via two connecting parts 24, 24 formed in a curved shape with an inclination higher on the indoor side and lower on the outdoor side, and the fitting part 23 is provided on the flat plate part 21. The vertical section is formed into a substantially inverted U-shape through the connecting portion 26 extending from the lower edge of the portion 21 toward the indoor side, and the lower end 27a of the indoor wall 27 of the fitting portion 23 is lower than the lower end of the connecting portion 26. It protrudes downward. In addition, the distance between the hook-shaped claw 14 and the flat claw 15 mentioned above is
The fitting portion 23 or the top portion 27b of the indoor wall 27
The dimension is determined to substantially match the dimension from the bottom end portion 27a to the bottom end portion 27a.

Further, a fitting piece 28 is provided longitudinally protruding from one end in the left and right direction of the flat plate part 21, and this fitting piece 28 is connected to the flat plate part 2 through a connecting part 29 which is slightly bulged toward the indoor side.
1, the upper part is continuous with the fitting part 22, and the lower part is cut out so as to be located on an extension line of the flat plate part 21. At the other end in the left and right direction of the flat plate portion 21, a fitting recess 3 whose horizontal cross section is approximately U-shaped is provided via a continuous portion 30.
1 is located on the indoor side of the flat plate portion 21. The fitting recesses 31 are machined to a height position corresponding to that of the flat plate part 21 and are provided along almost the entire height of the flat plate part 21, and the lower end of the fitting recess 31 is shown in a partial horizontal cross-sectional view. As clearly shown in FIG. 5, it is bent so as to be located on the upper surface of the continuous portion 26. The positional relationship between the fitting portion 28 and the fitting recess 31 with respect to the flat plate portion 21 is such that, in this embodiment, the fitting piece 28 is fitted to the left side of the exterior plate 20 and the fitting piece 28 is fitted to the right side when viewed from the indoor side, as shown in FIG. Although the mating recesses 31 are formed, it goes without saying that they can be arranged and formed in the left-right direction opposite to that described above.

Next, a method for roofing an outer wall using the exterior board 20 of this embodiment will be explained.

First, as shown in FIGS. 1 and 2, the first exterior plate 20 is attached to the top of the long metal attachment members 12 that are vertically arranged at appropriate intervals. This is done by fitting the indoor side wall 27 of the fitting part 23 of the exterior plate 20 between the hook-shaped claw 14 and the flat claw 15 of each mounting member 12, as shown in FIG. While maintaining this state, the flat claw 15 is struck from slightly below with a hammer or the like to deform it to the hook-shaped claw 14 side and lower the indoor wall lower end 27a.
and the flange 12b.
Although not shown, the upper end of the uppermost exterior plate 20 is attached to the mounting member 1 via an appropriate fixing device such as a screw.
2 or fixed to the beam of the building. In addition, the exterior plate 20
When fitting the fitting part 23 between the hook-shaped claw 14 and the flat claw 15, the outer plate 20 and the indoor wall 27 are elastically deformed as necessary so that the fitting part 23 can fit into the hook-shaped claw 14 bent downward. Let's make it possible. Next, the first exterior plate 20 and the other exterior plates 20 that are connected to the first exterior plate 20 in the lateral direction are fitted with the other fitting piece 28 into one fitting recess 31, and the fitting piece 28 is placed adjacent to the other fitting piece 28. It is supported on the continuous portion 26 of the exterior plate 20. Then, the fitting piece 28 is narrowed by the upper and lower connecting parts 24 and 26 and positioned in the vertical direction, and the fitting piece 28 is positioned in the left-right direction by contact between the connecting part 30 of the fitting recess 31 and the connecting part 29 of the fitting piece 28. do.

Next, in this way, a plurality of exterior plates 20, 20
... is laterally laid as many times as necessary, and then the exterior panels 20 are attached further to the lower level. To do this, first fit the fitting part 22 of the first exterior plate 20 on the lower side into the fitting part 23 of the exterior plate 20 directly above it, and then fit the fitting part 23 of the lower side exterior plate 20 in the same manner as described above. After fitting between the hook-shaped claw 14 and the flat claw 15, the flat claw 15 is caulked and fixed to the mounting member 12. Furthermore, in order to attach another lower side exterior plate 20 that is laterally connected to this lower side exterior plate 20,
The other fitting portion 28 of the fitting recess 31 of one of the other lower side exterior plate 20 and the first lower side exterior plate 20 is fitted. At this time, the other end of the lower side exterior plate 20 that will be attached later is slightly lowered and tilted in advance, and the fitting part 22 thereof is gradually moved to a horizontal position while fitting into the fitting part 23 of the upper side exterior plate 20. so that it fits into both the side and upper exterior plates 20. Further, the procedure for fixing the lower end fitting portion 23 of the lower-stage side exterior plate 20 attached later to the mounting member 12 has already been repeatedly explained.

The outer wall of the building is constructed by repeating this process all the way down to the lowest level.

Next, other embodiments regarding the application or shape of the mounting member 12 will be described. It should be noted that corresponding parts in each embodiment, including the above-mentioned embodiment, are denoted by the same reference numerals in the drawings.

First, FIG. 7 shows an example in which the sound insulation and heat insulation effects are enhanced. In this method, when the mounting member 12 is nailed to the stud 41 of the building via a fixing device 13 such as a nail, a first board 42 made of a wood wool board or the like is interposed, and this board 42 and the mounting member flange 1 are interposed.
2b, a second board material 43 made of wood wool board or the like is sandwiched between the board member 2b and the board member 2b. Needless to say, the second plate member 43 is squeezed between the mounting member 12 in the figure and another mounting member (not shown) adjacent thereto.

Other examples of the cross-sectional shape of the mounting member 12 are shown in FIG. 8 and subsequent figures. Mounting member 1 in Figure 8
2 has the same basic shape as that of the previous embodiment, but hook-shaped claws 14 and flat claws 15 are cut and raised on the groove bottom 12c, and flanges 1 are formed on both sides of the groove 12a.

The difference is that it is fixed by That is, in this case, the groove 12a of the mounting member 12 faces inside the building. 9 and 10 show the flange 12 of the groove bottom 12c of the mounting member 12 shown in FIG.
b, and groove bottom 12c.
The stepped portion 12d is formed by bending so that the width of the mounting member 12 becomes gradually narrower toward the end.
FIG. 10 shows an application example of this mounting member 12, in which a plurality of the mounting members 12 are fixed at equal intervals to the indoor wall surface 44 of the building via fixing devices 13 such as nails, and each of the adjacent mounting members 12 is , 12 stepped portions 12d,
A board material 45 made of wood wool board or the like is spanned over 12d, and then an exterior board 20 is attached. According to this embodiment, the plate material 45 is firmly held between the stepped portion 12d and the exterior plate 20, and the stepped portion 12 is sandwiched between the plate material 45 and the indoor wall surface 44.
An air layer 46 with a thickness corresponding to the height up to d
is ensured, resulting in extremely excellent heat insulation. Furthermore, FIG. 11 and FIG. 12 each show the stud 4
The flange 12 is attached only from one end side of the base portion 12e, which is nailed to the flange 12 through a fixing device 13 such as a nail.
The mounting member 12 having a cross-sectional shape with a raised side wall portion 12f having an angle b is shown. According to these, the amount of materials used and the weight for constructing the mounting member 12 can be reduced. In the case of FIG. 12, the side wall portion 12f is also raised from the other end of the base portion 12e, which is intended not only to reduce the weight, but also to support the exterior plate 20 (not shown) in the direction of the interior. This is intended to ensure the same level of rigidity as the first embodiment.

[Effects of the Invention] The present invention is configured as described above, and the plurality of exterior panels that are laterally installed are connected and engaged with the lower exterior panels at the fitting portions formed at the lower ends thereof. Because of the structure, a strong outer wall can be constructed by simply providing a small number of fixing points to the long metal mounting member. The exterior plate can be fixed to the mounting member by simply deforming the flat claw on the lower end side using, for example, a hammer while holding the fitting portion of the exterior plate between the claws. Therefore, the work is extremely easy and the construction time can be shortened. On the other hand, the positioning of the exterior plate with respect to the mounting member is done naturally using the hook-shaped claws and flat claws, and the leveling of the mounting member can be easily done by using the hook-shaped claws or flat claws as clues to easily stretch the thread or steel wire. It can be carried out. Therefore, in the present invention, construction workability and work efficiency are improved in terms of leveling work, and as a result, construction can be specifically completed in approximately one-third of the time required by conventional methods.

Further, as described above, the present invention does not require fixing tools such as nails or screws when attaching the exterior plate, so that a relatively inexpensive exterior structure can be achieved.
