Description

INDUSTRIAL APPLICABILITY The present invention is installed between a lower layer folded plate roof and an upper layer folded plate roof in a two-layer type folded plate roof, and can be easily and quickly attached to the lower layer folded plate roof, and the upper layer folded plate roof. The present invention relates to a roof support and a two-layer folded plate roof that can support a plate material very strongly.

Conventionally, a two-layer folded-plate roof (including steeply inclined walls) consisting of a lower-layer folded-plate roof and an upper-layer folded-plate roof has been constructed. exist in large numbers. In particular, due to recent weather conditions, measures against global warming, and enhancement of energy-saving measures, there is an increasing demand for double-layer folded-plate roofs, even for metal roofs, depending on the purpose of the building. These roofs include a new two-layer type roof and a modified roof in which a new roof is newly installed on top of an existing roof. The lower layer folded-plate roof is constructed with a metal folded-plate type roof plate material. Folded-plate roofs also exist that have a substantially wall-like shape constructed at a steep slope, and there are many such folded-plate roofs.

In this type of double-layered roof, many roofs are constructed of folded-plate roofing materials having lower and upper ridges. In some cases, a folded-plate roof is constructed by connecting the folded-plate roof plate members to each other. A support is provided between the upper folded-plate roof and the lower folded-plate roof, the support is mounted on the lower folded-plate roof, and the upper folded-plate roof is supported on the lower folded-plate roof by the support. It is supported.

In many of the folded-plate roofs of this type, the roof supports are installed on the lower-layer folded-plate roof using the raised-plate portions of the lower-layer folded-plate roof. In other words, the rake-type folded-plate roof has a structure in which the folded-plate roof plate is fixed to the roof supports only by connecting the hangers and the rake-fastening portions of the folded-plate roof plate members.

However, the rake part has a relatively small cross-sectional shape, and in the configuration in which the rake part is used to attach the roof support, the structure of the roof support tends to be complicated. . In addition, when negative pressure from the wind acts on each folded-plate roof plate material, the wider the flat surface is, the greater the negative pressure external force acts, and the folded-plate roof plate material is lifted upward. . In recent years, the number of large and powerful typhoons has increased due to changes in the natural environment, and the scale of these typhoons tends to increase.

For this reason, in a two-layer type folded-plate roof, there is a tendency that the joints between the folded-plate roof plates become dislodged from the roof supports and are blown away. There is a strong need to improve the durability of folded-plate roofs. Therefore, the bracket is devised to firmly fix the folded-plate roof plate material together with the hanger.

JP 2014-40720 A

Therefore, the region of the locking receiving portion (5) of the roof material mounting portion (3) in Patent Document 1 is small, and the locking range with the locking portion (12) of the folded plate roof material (10) is also narrow. The locked state is not necessarily perfect, and there is a good chance that the lock receiving portion (5) and the locking portion (12) will come off due to strong winds.

In addition, many of the Hachijime type roofs are of the Maruhase type. Therefore, in order to fix the joints of the folded-plate roof boards to the roof brackets, a hook for roof construction is required, and therefore, a space for placing the hooks on the roof bracket is required. becomes.

Thus, the above problem was solved.

In the first aspect of the invention, the clamping leg member includes the fitting mounting member and the clamping leg member, and the fitting mounting member has the base plate-shaped portion and the bulging portion. The holding leg member has two supporting legs, and the lower ends of both supporting legs have fitting projection pieces that protrude inward in the width direction (Y direction). The roof support according to the present invention is particularly suitable for being placed on the lower folded-plate roof of a two-layer folded-plate roof to support the upper folded-plate roof.

In particular, from the lower ends of the support legs of the roof supports toward the inside in the width direction (Y direction) with respect to the fitted bends formed in the rising portions of the folded-plate roof materials that constitute the two-layer folded-plate roof. The fitting protruding pieces formed by the above are fitted together, and both support legs are tightened with fasteners, so that the roof support can be fixed extremely strongly to the underlying folded-plate roof. An internal screw member is provided on the lower surface side of the clamping top portion of the clamping leg member and fixed by means such as welding. Welding and the fixing bolt work synergistically by screwing the fixing bolt together with fixing the hanger to the fixed inner screw member by screwing the fixing bolt to be fixed. The connection between the fitting mounting member and the clamping leg member can be made extremely strong.

Further, the base plate-shaped portion is rectangular, and both ends in the Y direction, that is, in the longitudinal direction, are used as fitting ends. That is, since both ends of the rectangular base plate portion in the Y direction are used as the fitting end portions, the fitting end portions are straight when fitted to the fitting bent portion of the folded-plate roof plate material. A large and effective matching range can be ensured.

In the fitting mounting member, the bulging portion has a structure that bulges upward from the base plate-like portion as a base, so that the bulging portion has a substantially shell-like structure or a substantially monocoque structure. . Therefore, the base plate-shaped portion and the bulging portion can mutually reinforce each other, and the fitting attachment member can have excellent mechanical strength.

A lower layer folded plate made of a folded plate roof plate material having a bent portion to be fitted to which the fitting projection piece of the support leg portion can be fitted and locked when constructing a two-layer folded plate roof. By loosening and tightening the fasteners to the roof, the roof supports can be easily and quickly installed on the lower folded plate roof.

In addition, by forming downwardly folded bent pieces at both the fitting end portions of the base plate-shaped portion, the mechanical strength of the fitting end portions at both Y-direction ends of the base plate-shaped portion is further increased. can be improved. Furthermore, by adding a configuration in which the corners of the Y-direction end faces of the bulging portion and the high top and low top are rounded to the above configuration, a folded plate can be attached to the fitting end of the fitting mounting member. When fitting the bent portion of the roof plate material, the roundness facilitates the fitting and makes it difficult for the bent portion to be damaged. Furthermore, in the invention of claim 1, the base plate-shaped portion of the fitting mounting member and the pinching top portion of the pinching leg member are welded together, so that the roof support can have an extremely strong structure. can.

According to the invention of claim 2, if the bulging portion of the fitting mounting member has a low apex formed on one side of the stepped rising surface portion and a high apex formed on the other side, it is possible to achieve a fastening type folding. In a shingle roof, the low top is suitable for the installation of a tie-down hanger. If the clamping top portion of the clamping leg member is formed in a flat shape, the fitting mounting member can be easily installed on the clamping top portion of the clamping leg member. Welding is suitable as a fixing means for the fitting attachment member to the clamping top portion, and the manufacture of the roof support can be simplified, making it suitable for mass production.

Both the support leg portions of the holding leg member are formed with hanging leg pieces, and the lower ends of the both hanging leg members are formed with flat leg pieces extending outward. If a structure in which an inclined leg piece is formed which is inclined outward and downward from the outer end of the piece, it is more suitable for a folded-plate roof plate material having a bent portion to be fitted.

In the invention according to claim 3 , a resin-coated portion is provided below and partly of both the fitting projection pieces and both the support leg portions of the clamping leg member. A resin-coated portion coated with a resin is provided below and partly of both the fitting projection pieces and both the supporting leg portions of the leg member. When the roof supports of the present invention are used to construct a two-layer folded plate roof, even if heat at high or low temperature is transmitted from the upper layer folded plate roof to the roof supports, The lower and part of both support legs of the sandwiching leg members of the roof support are covered with a resin coating portion, which blocks the transmission of heat to the lower layer folded plate roof and the interior of the lower layer folded plate roof. It can prevent low temperature or high temperature from being transmitted to the

In the fourth aspect of the present invention, a part of the fitting mounting portion is provided with a resin-coated portion that is coated with resin, so that the upper-layer folded-plate roof can be configured as an upper-layer folded-plate roof at high temperatures such as in summer. The sheet roof board material may thermally expand and contract along the longitudinal direction (X direction), resulting in misalignment with respect to the roof supports, which may generate vibration and noise. In such a case, the resin-coated portion of the fitting mounting member can minimize the generation of vibration and noise due to misalignment with the upper folded-plate roof, thereby suppressing the plate rattling phenomenon.

Hereinafter, an embodiment of a roof support A of the present invention and a two-layer folded plate roof B using the roof support A will be described with reference to the drawings. First, the roof support A according to the present invention will be described, and then the two-layer folded plate roof B using the roof support A will be described. The roof support A is suitable for use with a two-ply folded-plate roof B, which consists primarily of folded-plate-type metal shingles. In particular, the roof support A is suitable for use with a riveted-type folded-plate roof.

In the present invention, the X direction and the Y direction are used as terms indicating directions. The two-layer folded-plate roof B constructed by the roof support A of the present invention has a plurality of folded-plate roof members 8, 8, . (See FIGS. 1(A) and 5(A), etc.). Also, the longitudinal direction of each folded-plate roof plate material 8 is defined as the X direction. Therefore, the longitudinal direction of the structural member to which the roof support of the present invention is attached is the Y direction [see FIG. 1(A)]. These X and Y directions also apply to the roof support A, and follow the X and Y directions of the two-layer folded plate roof B in a state of being incorporated into the two-layer folded plate roof B. Also, the X direction may be recognized as the front-rear direction. The X direction and Y direction are shown in the figure.

The roof support A in the present invention is basically composed of a fitting mounting member A1 and a clamping leg member 5. As shown in FIG. The present invention has a plurality of embodiments, each of which is composed of a fitting attachment member A1 made of metal and a clamping leg member 5 made of metal. There are two types of mating attachment A1. A point common to the two types is that they are composed of a base plate-like portion 1 and a bulging portion 2 (see FIGS. 1(B), 2, etc.). There are two types of fitting mounting member A1, and the folded plate roof to be constructed is divided into a fastening type folded plate roof (see Fig. 1) and a fitting type folded plate roof (see Fig. 6). .

The first type is suitable for a fastened type folded-plate roof. [See FIG. 2(A), FIG. 3, etc.]. The plate thickness of the base plate portion 1 is normally about 2 to 2.5 mm for reference.

The bulging portion 2 is a portion that is a convex bulge when viewed from above the base plate-like portion 1 and a concave portion when viewed from below. It has a closed structure [see FIGS. 1(B), 2(A), (B), and 3]. Specifically, it is shaped like a substantially rectangular container in which a capsule is divided in half. The bulging portion 2 has a substantially rectangular shape when viewed from above, and its four corners are rounded, that is, formed in an arc shape [Figs. etc.].

Further, the bulging portion 2 is formed to have a maximum area so as to be accommodated inside the base plate-shaped portion 1 [Figs. reference〕. That is, the planar shape of the bulging portion 2 is set to occupy a large proportion of the range of the planar shape of the base plate portion 1 (see FIGS. 2A, 3A, and 3B). The four corners of the bulging portion 2 are arc-shaped, so that the four corners of the base plate-like portion 1 are left as flat portions. In addition, there remains a slightly substantially flat portion near the long side of the base plate portion 1 (see FIGS. 1(B), 2(A), (B), and 3, etc.).

The bulging portion 2 is provided with a step rising surface portion 21 at an intermediate portion in the Y direction [see FIGS. 1(B), 2(A), 3, etc.]. The step rising surface portion 21 is a substantially vertical surface that is orthogonal to the Y direction or the longitudinal direction of the bulging portion 2 . A portion on one side in the Y direction of the step rising surface portion 21 is a low top portion 22 , and a portion on the other side in the Y direction is a high top portion 23 . The low apex 22 is positioned lower than the high apex 23 (see FIGS. 1(B), 2(A), 3, etc.).

The lower top portion 22 is a portion to which a hanger is fixed, specifically a portion to which a tightening hanger 86, which will be described later, is attached. 2, see Figure 3, etc.). The hanger fixing hole 22a is a portion through which the threaded shaft portion of the fixing bolt 42 for fixing the later-described tall tightening hanger 86 on the low top portion 22 is inserted. Specifically, the diameter of the hook fixing hole 22a is preferably such that the screw shaft portion of the fixing bolt 42 can be loosely inserted (inserted with a margin).

Both side surfaces of the bulging portion 2 in the Y direction (longitudinal direction), that is, the outwardly facing side surfaces of the low top portion 22 and the high top portion 23 are formed as inclined surfaces that are outwardly inclined from above to below. It is An inclined surface continuous to the low top portion 22 side is called a low inclined surface 24, and an inclined surface continuous to the high top portion 23 side is called a high inclined surface 25 [FIGS. etc.]. A corner portion 22t between the low top portion 22 and the low inclined surface 24 is rounded in an arc shape.

Similarly, a corner portion 23t between the high top portion 23 and the high slope surface 25 is also rounded (see FIGS. 1(B), 2(A), (B), and 3). Further, side surface portions 26, 26 are formed on both sides along the X direction of the fitting mounting member A1. The side surface portion 26 is a side surface continuous in the Y direction over the low top portion 22, the high top portion 23, the low inclined surface 24 and the high inclined surface 25 (see FIGS. 2A, 2B and 3).

Both ends of the base plate portion 1 in the longitudinal direction, that is, in the Y direction are mating end portions 11, 11 [see FIGS. ]. Both the fitting ends 11, 11 are the opposite short side portions of the rectangular base plate portion 1 and form straight edges. Both of the fitting ends 11, 11 are fitted to the fitting bent portions 84, 84 of the folded-plate roof plate material 8 of the lower-layer folded-plate roof B1 constituting the two-layer folded-plate roof B, which will be described later. It serves to secure the roof support A to the shingle roof B1 (see FIG. 1). In other words, the entire fitting end portion 11 of the base plate portion 1 can abut on the fitted bent portion 84 of the folded-plate roof plate material 8 . The fitting end portion 11 is positioned at the same position as the lower ends of the lower inclined surface 24 and the higher inclined surface 25 of the bulging portion 2 .

Both of the fitting end portions 11, 11 are formed with bending pieces 11a folded toward the lower surface side of the base plate portion 1 (see FIGS. 2A and 3). Both bending pieces 11a are formed to have a substantially horizontal "U" cross-sectional shape (see FIGS. 1(B), 2(A), 3, etc.). Alternatively, it is bent so as to form a substantially reversed "V" shape.

By forming both bent pieces 11a at both fitting end portions 11, 11 of the base plate portion 1, the mechanical strength of both fitting end portions 11, 11 can be improved, and the folded-plate roof plate material 8 can be folded. The contact state with the fitted bent portion 84 can be made more reliable. Furthermore, when the fitted bent portion 84 of the folded-plate roof plate material 8 is fitted to the fitting end portion 11 of the fitting mounting member A1, the inner surface side of the folded-plate roof plate material 8 is prevented from being damaged. be able to.

As a first modified example of the fitting mounting member A1, the area occupied by the bulging portion 2 with respect to the base plate portion 1 is reduced. In this embodiment, many flat portions of the base plate portion 1 appear. That is, in the fitting mounting member A1 in the first modified example, the base plate-like portion 1 has a wide portion where the bulging portion 2 is not formed, and both sides of the base plate-like portion 1 in the Y direction are present. Flat portions are present not only in the portion but also in both sides in the X direction.

Further, as a second modification of the fitting mounting member A1, the lower inclined surface 24 and the higher inclined surface 25 of the bulging portion 2 may be substantially vertical. As a result, the fitting mounting member A1 can further narrow the forming range of the bulging portion 2 and enlarge the flat portion of the base plate-shaped portion 1 . As in the second modified example of the fitting mounting member A1, the shape of the fitting end portions 11, 11 of the base plate-like portion 1 is reduced by reducing the formation area of the bulging portion 2 with respect to the base plate-like portion 1. protrudes further, and the angle of the bent piece 11a portion at the fitting end portion 11 becomes even more acute, so that it can be easily bitten into the fitted bent portion of the folded-plate roof plate material, and the folded-plate roof plate material 8 for the roof The fixed state with respect to the support can be further strengthened.

In the fitting mounting member A1 of the first modification and the second modification as well, as described above, the base plate portion 1 is formed with the bulging portion 2 so that the bulging portion 2 halves the capsule. It is shaped like a split container. Therefore, the bulging portion 2 has a substantially shell-like structure or a substantially monocoque structure, and the base plate-like portion 1 and the bulging portion 2 can mutually reinforce each other. Synergistically, it can be made excellent in mechanical strength.

Next, the clamping leg member 5 is composed of a clamping top portion 51, support leg portions 52, 52, fitting projection pieces 53, 53, a fastener 55, etc. [Figs. 1(B) and 2(A)] , (D), see FIG. 3A]. The clamping top portion 51 is formed as a flat surface (see FIGS. 1(B), 2(A), and 3(A)). The clamping top portion 51, the support leg portions 52, 52, and the fitting projection pieces 53, 53 are integrally formed from a single metal strip material by press working or the like [Figs. ), see FIG. 3(A), etc.].

On the clamping top portion 51 is a portion on which the fitting mounting member A1 is mounted and fixed. Specifically, the fitting attachment member A1 is fixed on the clamping top portion 51 by welding. For this reason, the clamping top portion 51 is preferably formed to have a flat surface so that welding can be easily performed. The fitting mounting member A1 is preferably connected so that the center in the width direction (Y direction) and the center in the width direction (Y direction) of the clamping top portion 51 of the clamping leg member 5 match or substantially match. A connecting fixing hole 51a is formed in the clamping top portion 51 (see FIGS. 2A, 2B, 2A, 2D, 3, etc.). An internal screw member 41 is fixed to the lower surface side of the clamping top portion 51 and to the portion where the connection fixing hole 51a is formed [Figs. ), etc.].

In order to achieve such a configuration, the position of the hanger attachment hole 22a formed in the lower top portion 22 of the fitting mounting member A1 and the position of the connection fixing hole 51a of the clamping top portion 51 of the clamping leg member 5 are adjusted. , the position in the width direction (Y direction) of the connection fixing hole 51a formed in the clamping top portion 51 is biased to one side in the width direction (Y direction) of the clamping top portion 51 [Fig. B), see FIG. 2(A)].

Therefore, the internal screw member 41 is also fixed to the lower surface side of one side of the clamping top portion 51 in the width direction (Y direction) in accordance with the position of the connection fixing hole 51a. Welding is used as means for fixing the inner screw member 41, and this welded portion is called a welded fixing portion W1 [see FIGS. 1(B), 2, and 3(B)]. Here, one side refers to either the right end side or the left side end side in the width direction (Y direction).

The internal screw member 41 is a cylindrical member having an internal screw 41a therein. Specifically, the internal screw 41a is formed inside a metallic cylindrical member. The screw shaft portion of the fixing bolt 42 is screwed into the internal thread 41a (see FIGS. 1(B) and 2(A)).
