Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof plate mounting bracket for mounting a metal roof plate called a folded plate on a base material.

[0002]

2. Description of the Related Art There are various types of structures for mounting roof panels as described above. For example
As disclosed in Japanese Patent No. 537773, there is one in which an engaging portion having a substantially V-shaped cross section is formed to bulge outward at an upper portion of a rising portion rising obliquely.

The fitting for attaching such a roof plate is provided with a rising portion rising obliquely upward from the end of the horizontal fixing portion in accordance with the cross-sectional shape of the roof plate, and the upper ends of these rising portions arranged in a V shape are arranged. It has a shape in which it is connected by a receiving portion, and is formed by bending a strip-shaped metal plate.
Further, a locking claw for locking the roof plate is cut and raised at the upper part of the rising portion.

It is preferable to use the roof plate and the mounting bracket having such a structure because a relatively firm mounting state can be obtained.

However, when the locking claws are cut and raised in this manner, the positional relationship between the locking claws and the rising portion is constant and cannot change.

For this reason, since the roof is generally inclined from the ridge to the eaves, if the upper surface of the base material for fixing the mounting metal is not inclined, another member is attached in advance to incline the inclined surface. I had to install it later.
However, this work is troublesome and leads to a longer construction period, and if there is a mistake, it is difficult to redo it.

Further, if the roof is installed while ignoring the slope, even if the slope of the roof is extremely gentle, the roof plate will be overloaded and a firm mounting state cannot be obtained.

[0008]

SUMMARY OF THE INVENTION Therefore, the main object of the present invention is to enable easy and rational roofing while obtaining a strong fixed state.

[0009]

[Means for Solving the Problems] The means for achieving this is to install a roof plate provided on a main body frame for fixing a locking claw for locking an engaging portion formed at a lower portion of a rising portion of the roof plate on a base material. A metal fitting, wherein the locking claw is formed by mounting a locking claw member which is separate from the main body frame, and the locking claw member follows the inclination of the roof plate to be mounted with respect to the main body frame. It is a roof plate mounting bracket that is rotatably mounted.

That is, when the roof is raised, the main body frame is first fixed to a predetermined position on the base material. At this time, it is not necessary to consider whether the upper surface of the base material is inclined according to the slope of the roof. Subsequently, the roof plate is placed, and the engaging portion of the roof plate is locked to the locking claw member. Since the locking claw member is rotatable with respect to the main body frame, this locking only needs to be carried on the roof plate, and when the locking claw member locks the engaging portion, the locking claw member is It is in a state of rotating so as to correspond to the gradient of. By the locking, the installation of the roof plate is completed.

As the roof plate used here, it is preferable to use one having a structure in which a buffer portion is connected to an engaging portion formed in the lower portion of the rising portion. That is, by forming a groove having a triangular cross-section with respect to the rising portion, the engaging portion is formed on the inner surface side above the groove, and the lower end of the engaging portion has an acute angle with respect to the engaging portion. It is advisable to form the above-mentioned buffer portion which is connected to the rising portion with an obtuse angle. In such a roof plate, when negative pressure is applied, deformation occurs upward in the lower part of the roof plate, that is, in the flat part and the rising part, but since the engaging part is formed in the lower part of the rising part, It is possible to suppress the deformation of the flat portion and the rising portion at a small stage, and it is difficult to transmit the deformation to the engaging portion. Further, since the deformation of the rising portion is small in this way, it is possible to prevent the engaged fastener portion from opening. In addition, since the buffer portion that does not transmit the deformation below the engaging portion of the rising portion is formed under the engaging portion of the roof plate, the above effect can be further improved.

The top surface of the main body frame may be formed to be convex upward and curved along the front-rear direction. Supports sloping roof boards without damaging them.

If the tip of the locking claw member that comes into contact with the roof plate is set to have a relatively short dimension about the center of rotation or if the corner is curved, the outside of the locking claw member will be removed. Even if the side surface is tilted, the amount by which the tip of the locking claw member projects when rotated can be suppressed, so that reliable locking can be performed and the contact portion with the roof plate can be wide. It can contribute to firm fixation.

Further, if the engaging claw member is attached by using a stepped bolt or a stepped rivet, it can be manufactured relatively easily and inexpensively, and the rotation can be performed mainly with the bolt or the rivet. Rotation of the locking claw member is also smooth. Another means is a roof structure using the roof plate mounting bracket.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing the structure of a roof 1. This roof 1 has locking claws 4 of a roof plate mounting bracket 3 (hereinafter referred to as a bracket) fixed on a base material 2.
Then, the engaging portion 6 of the metal roof plate 5 (folded plate) is locked, and the adjacent roof plates 5 are fastened and coupled to each other to raise the roof.

First, the roof plate 5 is, as shown in FIG.
As a whole, a flat portion 5a having an appropriate width is formed at an intermediate portion in the left-right direction, and rising portions 5b and 5b are raised from both sides of the flat portion 5a toward the outer oblique upper side, and from the upper end of these rising portions 5b to the outer side. The tops 5c extending horizontally toward the roof, and from the tips of these tops 5c, the fasteners 5d, 5e that can be locked to each other with another adjacent roofing plate 5
Is a standing shape. And the rising portion 5b,
The engaging portion 6 and the buffer portion 5f are formed on the lower side of 5b. That is, by forming a groove having a triangular cross-section with respect to the rising portions 5b, 5b, the engaging portion 6 is formed on the inner surface side above the groove, and the lower end of the engaging portion 6 is engaged. The buffer portion 5f is formed that is connected to the portion 6 at an acute angle α and is connected to the rising portion 5b at an obtuse angle β.

The metal fitting 3 comprises a main body frame 7 and a locking claw member 8 having the locking claw 4. The main body frame 7 is formed by bending a strip-shaped metal plate, and is formed in a mountain shape that fits under the connecting portion of the roof plate 5. That is, the fixing pieces 7a are provided on both left and right sides, and the fixing pieces 7a are
A rising piece 7b that extends obliquely upward from the inner edge of is extended. Then, the upper ends of these rising pieces 7b are connected to each other by the piece 7c. The receiving piece 7c is formed in a shape in which the upper surface is convex upward and curved in the width direction (front-back direction), and the front and rear side edges of the receiving piece 7c and the rising piece 7b are bent downward to reinforce the shape. The piece 7d is formed. Further, a reinforcing rib 7e that is convex upward is provided from the lower portion of the rising piece 7b to the fixed piece 7a.

A recess 7f is also formed in the receiving piece 7c, and a positioning metal fitting 9 is fixed to the recess 7f.

The positioning metal member 9 includes a vertical piece 9a interposed between the fastening portions 5d and 5e of the adjacent roof plate 5, and the vertical piece 9a.
and a fixed piece 9b for supporting a. The recess 7f has a size and a width sufficient to accommodate the fixing piece 9b, and is fixed by the rivet 10. It may be bolted or fixed by welding. Further, the fixed position is set so that the vertical piece 9a is located at the middle in the left-right direction.

The locking claw member 8 is formed to be relatively narrow, close to the width dimension of the main body frame 7, and fixed to the lower portion of the rising portion 7b of the main body frame 7. That is, a square through hole 7g is formed at a fixed position of the rising portion 7b, and the locking claw member 8 attached through this through hole 7g is shown in FIG.
As shown in FIG.
And a protruding piece 8b protruding outward from the lower end edge of the overlapping piece 8a.
And the locking claw 4 extending obliquely downward from the tip of the projecting piece 8b. A round through hole 8c is formed in the center of the polymerized piece 8a, and the polymerized piece 8a is rotated about the through hole 8c in either the front or rear direction.

From the overlapping piece 8a to the projecting piece 8b and the locking claw 4, the bending piece 8 is bent to the left and right side edges to the lower surface side.
In order to improve the strength by forming d, the press is made so that the bending piece 8d of the overlapping piece 8a does not hit the main body frame 7 during the above rotation so that the upper and lower portions in the length direction are wide. Deform by processing. Material cost can be reduced rather than widening the whole, and the above-mentioned deformation further increases the strength of the polymerized piece 8a.

The width of the locking claw 4 of the locking claw member 8 is set to be relatively short with respect to the center of rotation so that the locking claw 4 which is inclined is locked when it is rotated. Since the amount by which the claws 4 project is suppressed, reliable locking can be performed by this, and the contact portion with the roof plate 5 can be widened, which contributes to a firm fixing.

The locking claw member 8 is attached by inserting a bolt into each of the through holes 7g and 8c, and a stepped bolt 11 is used as the bolt. This stepped bolt 11
The stepped portion 11a is set to be slightly thicker than the combined thickness of the main body frame 7 and the overlapping piece 8a, and has a root corner portion 11b at the lower part that fits into the through hole 7g of the main body frame 7.
The stepped bolt 11 is inserted from the lower surface side into the through hole 7g formed in the main body frame 7, and the nut 1 is attached to the male screw portion 11c.
By engaging 2 with each other, the locking claw member 8 is attached in a rotatable state.

In order to raise the roof 1 using the metal fitting 3 constructed as described above, first, the metal fitting 3 is fixed to a predetermined position on the base material 2. It may be fixed by welding. continue,
The roof plate 5 is placed on the base material 2 from above, and the engaging portions 6 of the rising portions 5b of the roof plate 5 are locked by the locking claws 4 of the metal fitting 3. With the metal fitting 3 just fixed on the base material 2, the locking claw member 8 is rotatable in any of the front and rear directions as shown in FIG. Therefore, when the roof plate 5 is placed and locked, the locking claw member 8 freely moves. That is, it is possible to fix the roof plate 5 in accordance with the required gradient when the roof plate 5 is attached.

An imaginary line 5c in FIG. 5 indicates the inclination of the roof plate 5, and the locking claw member 8 automatically tilts at an angle corresponding to this inclination to lock the roof plate 5. When fixing the metal fitting 3,
In addition to not having to worry about the inclination of the upper surface of the base material 2, the locking claw member 8 rotates in either the front or rear direction, so the direction of the front and rear direction of the metal fitting 3 does not matter, and the direction is simple and quick. You can perform various fixing work. In addition, the receiving piece 7 of the main body frame 7
Since the upper surface (top surface) of c is formed to be convex upward and curved along the front-rear direction, the roof plate 5 can be supported without being damaged.

After the roof plate 5 is locked to the metal fitting 3, the fastening portions 5d and 5e of the roof plate 5 may be connected to each other.

As described above, since the roof inclination can be automatically coped with without considering the inclination of the base material 2 when fixing the metal fitting 3, the roofing operation is simple and can be performed in a short time.

Further, since the roof plate 5 has a structure in which the cushioning part 5f is connected to the engaging part 6 formed in the lower part of the rising part 5b, the roof plate 5 is subjected to a negative pressure. Lower part, that is, the flat portion 5a and the rising portion 5b
However, since the engaging portion 6 is formed in the lower portion of the rising portion 5b, the deformation of the flat portion 5a and the rising portion 5b can be suppressed at a small stage. Can be difficult to convey to. Further, since the deformation of the rising portion 6 is small as described above, it is possible to prevent the engaged fastening portions 5d and 5e from opening. In addition, under the engaging portion 6 of the roof plate 5, a rising portion 5b is provided.
Since the buffer portion 5f which does not transmit the deformation below the engaging portion 6 in the above is formed, the above effect can be further improved.

Since the locking claw member 8 is formed separately from the main body frame 7, the structure of each member can be simplified.
The process is easy, and the cost can be reduced. The mounting can be performed by the stepped bolts 11, the assembling work is extremely easy, and the manufacturing cost can be reduced.
In addition, since the rotation can be performed around the stepped bolt 11, the rotation of the locking claw member 8 is also smooth.

FIG. 6, FIG. 7 and FIG. 8 show a metal fitting 3 according to another example.
FIG. That is, in the metal fitting 3 of FIG. 6, the locking claw member 8 is formed without forming the bent pieces 8d on both front and rear edges, and the ribs 8e that are convex upward are formed on both the left and right sides for reinforcement instead. ing. The metal fitting 3 of FIG. 7 is also formed of a single metal plate, but the locking claw 4 of the locking claw member 8 is formed by bending from below. The metal fitting 3 in FIG. 8 is formed by pressing a single metal plate into a thin box shape having three walls integrally formed around the metal plate, and locking claws 4 are formed on both front and rear edges thereof. . By forming it into a thin box shape, the locking claw member 8 having high strength can be obtained. Each of the locking claws 4 has rounded corners to soften the contact with the roof plate 5. Since the parts other than the above parts are the same as those in the above description, the same reference numerals are given and detailed description will be omitted.

[0031]

As described above, according to the present invention, when mounting the roof plate, after fixing the roof plate mounting metal fitting at a predetermined position, the roof plate is placed and the engaging portion is used as the locking claw member. All you have to do is lock it. That is, there is no need to consider the inclination of the upper surface of the base material, and the work of inclining the upper surface of the base material in advance is not necessary, and the work can be performed simply and quickly, which contributes to shortening the construction period. Further, since the locking claw member automatically rotates to follow the slope of the roof to lock the roof plate, it is possible to obtain a firm fixed state without forcing the roof plate.

Further, since the locking claw member is formed separately from the body frame, the structure of each member can be simplified. Therefore, the processing is easy and the cost can be suppressed. Moreover, the attachment may be performed by, for example, stepped bolts or stepped rivets, and the assembling work is easy.
