Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal panel used for a wall or a roof, and more particularly to a roof panel which is easy to construct and has excellent water resistance, a suspension thereof, an engaging structure and a construction method. Regarding

[0002]

2. Description of the Related Art Generally, the structure of a metal roof panel is
As shown in FIG. 10, the suspension 71 is fixed to the side of the base plate 70, and the drain 72 is installed so as to be arranged inside the suspension 71, and the engaging portion 71 a of the suspension 71,
71a, engaging portions 73a, 73 of the roof panels 73, 73
a is engaged. Then, the cap 74 is fitted into the gap between the roof panels 73, 73, and the roof panel 7
The engagement portions 74a, 7 of the cap 74
4a is engaged.

Therefore, even if rainwater that has fallen on the roof panel 73 enters from the abutting position of the roof panel 73 and the cap 74, the drain 72 is arranged at the position where the rainwater drips. Is discharged to the outside. Since roof members such as the roof panel 73 and the drain 72 are bent by a bending machine, a bending machine corresponding to the number of roof members is required.

[0004]

However, the above roof members such as the roof panel, the cap, and the suspension have the following problems. The number of roof parts such as roof panels, suspensions, caps, drains, etc. was large, and it took a lot of time and effort to build the roof.

Since the number of parts of the roof member is large, a bending machine corresponding to those roof members is required. Especially, when it is necessary to perform on-site processing, transportation of the bending machine and installation space of the bending machine are required. The effort, such as securing, has dramatically increased.

[0006] Since the roof panel uses the cap, there are two places where rainwater penetrates on both sides of the cap, and the amount of infiltration into the roof panel inevitably increases.
The increase in the amount of rainwater flowing in the drain causes the evaporation of rainwater and the moisture that has permeated and evaporated due to the capillary phenomenon to cause corrosion of the back side of the roof panel and the cut edge of the roof panel, and leakage of rainwater. Became.

Since the drain is placed on the waterproof paper and used, the waterproof paper laid over time adheres to the bottom surface of the drain. Therefore, each member has thermal expansion,
The waterproof paper was torn by moving from its original installation position due to the vibration of the wind, and the waterproof function of the original waterproof paper was deteriorated. For roof panels that use caps, after engaging the roof panels with the suspenders, the caps are installed between the roof panels, so it is necessary for the operator to ride on the roof panels, and the roof panels need to be recessed. It was causing such things as.

When the suspension and the roof panel are engaged with each other, a gap is opened at the engaging position, so that the roof panel flaps under the influence of wind and the like, which promotes deterioration of the roof panel. In addition, the opening of the gap at the engaging portion facilitated infiltration of rainwater.

When the drain is installed so as to be lateral to the inclination of the roof, the rainwater remains in the drain, especially when a steel plate roof panel is used. A large amount of humidity is applied to the small edge (cut edge) and the back side of the roof panel to accelerate the occurrence of rust,
This caused damage to the roof panels.

The present invention was devised to solve the above-mentioned problems. The number of roof members is reduced and the appearance is not impaired, the construction time and labor are shortened, and a single bending process is performed. A machine is sufficient, and it prevents rainwater from invading the inside of the roof panel, except for the cause of damage to the waterproof paper on the base plate.Furthermore, it can be installed without the operator riding on the roof panel that has already been installed. It is an object of the present invention to provide a roof panel that can minimize the work of allocating the suspension and can strengthen the engagement between the suspension and the roof panel, the suspension, the engaging structure, and the construction method.

The folding stepped portion 10 of the roof panel 1 can be engaged with the bending fixing portion 32 of the one rising portion a. Note that the same configurations as those in FIG.

Next, as shown in FIG. 3, another form of the roof panel will be described. The same components as those in FIG. 1 will be described with the same reference numerals. The roof panel 1 includes first and second engaging portions 3 and 7 at one end and the other end of a flat flat portion 2. The first engagement portion 3 includes a bent portion 4 formed by folding one end of the flat portion 2 toward the flat portion 2 side, and a vertical portion 5 formed by bending the tip side of the bent portion 4 downward. The vertical portion 5 is composed of a goby engaging portion 6 which is formed by bending the tip end side upward at a predetermined angle.

Further, as shown in FIG. 3, the second engaging portion 7 has an abutting portion 8 in which the other end of the flat portion 2 is formed in a stepped manner,
A hanging portion 9 formed by extending downward from the contact portion 8;
A horizontal support portion 11 is formed by bending the lower end side of the hanging portion 9 in the horizontal direction, a projecting portion 12 formed by projecting one end side of the horizontal supporting portion 11 downward, and one end of the projecting portion 12 stands up. It is composed of the engagement rising portion 13 formed above. The roof panel 1 has a heat insulating material on the back side,
A backup member 38 is provided.

Further, as shown in FIG.
Is a fastening portion 21 that is fastened to the base plate 35, and a rising portion 23 that is formed by standing up from the vicinity of one end side of the fastening portion 21.
A mounting portion 22 formed on a part of the retaining portion 21 separated by the rising portion 23, a bending portion 24 formed by bending the upper end side of the rising portion, and one of the bending portions 24. An extension support portion 25 formed horizontally from the end, and a locking projection 2 formed by bending the tip end side of the extension support portion 25 downward.
7 and an abutment support portion 28 formed below the locking projection 27 via the attachment portion 26.

The suspension 20 has a rising portion 23.
The curved portion 24 and the curved portion 24 form a first locking portion A of the suspension 20, and the locking protrusion 27, the mounting portion 26, and the contact support portion 28 form a second locking portion B. In addition, in FIG. 1, a bent portion is provided at an intermediate position of the hanging portion 9, but this portion is necessary when fixing with a suspender, and in the configuration of the roof panel 1 shown in FIG. It doesn't matter.

Therefore, as shown in FIGS. 4 and 3, when the roof panel is attached to the roof portion of the building, the following procedure is performed. First, as shown in FIG. 4 (a), the first engaging portion (not shown) of the first roof panel 1 is engaged with the starting position of the roof, and the second engaging portion of the roof panel 1 is
Move the suspension 20 from the position of the solid line to the position of the virtual line,
The engaging rising portion 13 of the second engaging portion is connected to the first
The protrusion 12 of the roof panel 1 is placed and supported on the placing portion 22 of the suspension 20 while being locked by the engaging portion A. Then, the hanger 20 is fixed to the side of the base plate 35 by a fastening means such as a bolt.

Next, as shown in FIG. 4B, the first engaging portion 3 of the adjacent roof panel 1 is connected to the second engaging portion of the suspension member 20.
When pushed downward from between the supporting portion 26 and the hanging portion 9 of the existing roof panel 1, as shown by a solid line to a virtual line in FIG. 4B, the lower surface of the bent portion 4 of one roof panel 1 The side presses the upper surface of the contact portion 8 of the existing roof panel 1 via the seal member 36, and the lower end portion of the goby engaging portion 6 presses the seal member 37 on the horizontal support portion 11 of the existing roof panel 1. . The seal members 36 and 37 are attached in advance to the contact portion 8 of the roof panel 1 and the horizontal support portion 11 at predetermined positions.

Therefore, as shown in FIG. 4C, the second
The protruding portion 12 of the engaging portion 7 serves as a fulcrum on the mounting portion 22 of the hanging member 20, elastically deforms the second engaging portion 7 portion of the existing roof panel 1 downward, and the goby engaging portion 6 of the roof panel 1 is formed. Temporarily descends below the locking projection 27 of the suspension 20 (see FIG.
(C)) After that, the elastically deformed second engaging portion 7 is restored, so that the goby engaging portion 6 engages with the second engaging portion B of the suspension 20 as shown in FIG. 3. The protrusion 27 can be reliably engaged. In addition, since the abutting portion 8 of the existing roof panel 1 and the bent portion 4 of the adjacent roof panel 1 abut and support each other stronger, the abutting portion 8 and the bent portion 4 are It becomes difficult to infiltrate rainwater from between. Of course, the waterproof property can be enhanced by providing the seal member 36 between the contact portion 8 and the bent portion 4.

In the vicinity of the first engaging portion of the flat portion 2 of the roof panel 1, a concave portion 2 formed along the roof inclination direction is formed.
a. Therefore, a gap can be formed at the joint portion of the roof panels 1 and 1 (the position of the bent portion 4 of the first engaging portion and the contact portion 8 of the second engaging portion) at substantially the same distance as the concave portion 2a. When installed, it looks as if a cap had been installed, giving it an accent on the exterior and a good-looking appearance. Also,
A plurality of concave portions 2a may be provided at predetermined positions on the flat portion 2 in the vicinity of the second engaging portion 7 of the roof panel 1.

Even if rainwater comes in through the joint between the roof panels 1 and 1, the second engaging portion 7 can serve as a drain as a whole. That is, most of the invading rainwater flows through the space surrounded by the hanging portion 9, the seal member 37 and the vertical portion 5 and is discharged.
This is because the goby engaging portion 6 engages with the suspender 20 due to the elastic deformation of the second engaging portion with the protruding portion 12 as a fulcrum, so that the bent portion 4 and the contact portion 8 interpose the seal member 36 therebetween. This is because they come into firm contact with each other, and rainwater that enters the inside is minimized. Further, since the seal member 37 located below the goby engaging portion 6 is not irradiated with sunlight, deterioration due to ultraviolet rays does not occur and its waterproof function can be maintained for a long time.

Therefore, the laying direction of the roof panel 1 is
Rainwater will not be adversely affected when it is laid from high to low or laterally. This is because rainwater easily accumulates in the drain (in the space surrounded by the hanging portion 9, the seal member 37 and the vertical portion 5) when the roof panel 1 is laid horizontally, and the vaporized water vapor evaporates. This is because the inside of the seal member 36 is prevented from entering the inside of the seal member 36 to the outside, or most of it is discharged to the outside from the seal member 36 side or to the outside from the discharge port.

Further, since the protruding portion 12 of the second engaging portion supports the second engaging portion on the mounting portion of the suspender 20, the lower surface of the horizontal supporting portion 11 of the second engaging portion 7 is , Are engaged in a state of being separated from the side of the base plate. Therefore, even if the waterproof paper (not shown) is provided on the side of the base plate 35, it does not cause the deterioration of the waterproof paper.

Next, another embodiment of the present invention will be described. Since the suspension 20 has the same configuration as that described above, the same reference numerals are used in the description. FIG.
As shown in (a), the roof panel 1A includes a first engaging portion 3a and a second engaging portion 7a on one end side and the other end side thereof. The first engaging portion 3a has a bent portion 4a formed by bending the flat portion 1a of the roof panel 1A, a vertical portion 5a extending downward from the bent portion 4a, and a tip end side of the vertical portion 5a. It is configured by a goby engaging portion 6a formed by bending upward at an angle.

The second engaging portion 7a has a flat portion 1a.
At a predetermined position as a bent portion 8a, the bent portion 8a is bent downward to form a hanging portion 9a, and the lower end side of the hanging portion 9a is bent in the horizontal direction.
And one end of the horizontal support portion 11a is projected downward to form a projection 12a, and the projection 12 is formed.
The engagement rising part 13a is formed by rising from one end of a.

On the other hand, the suspender 20 for engaging the roof panel 1 has a stopper portion 21, a rising portion 23, a mounting portion 22, and
The curved portion 24, the extension support portion 25, the locking protrusion 27, the attachment portion 26, and the contact support portion 28 are included. The suspension 20 constitutes the first locking portion A by the rising portion 23 and the curved portion 24, and the locking projection 27 and the mounting portion 26.
And the contact support portion 28 constitutes a second locking portion B.

Therefore, the roof panel 1A is attached to the suspender 20.
When the roof panel 1A is attached by engaging with, the procedure is the same as the procedure shown in FIG. That is, first, if the first roof panel 1A is to be laid vertically, it is located on the higher side, or if it is to be laid horizontally, it is located at either the left or right end, and the first engaging portion of the roof panel 1A is predetermined. Engage in position (not shown). Then, the first locking portion A of the suspender 20 is engaged with the engaging rising portion 13a of the roof panel 1A, and the mounting portion 22 of the suspender 20 mounts and supports the protrusion 12a of the roof panel 1A. In this state, the suspension 20 is fixed to the base plate 35 with bolts or the like.

Next, the first engaging portion 3a of the adjacent roof panel 1A is lowered downward between the second engaging portion 26 of the hanging member 20 and the bent portion 8a of the existing roof panel 1A. Then, the lower end of the first engaging portion 3a presses the second engaging portion 7a downward via the seal member 37 provided on the horizontal supporting portion 11a of the existing roof panel 1A.

Therefore, the second engaging portion 7a elastically deforms downward with the protruding portion 12a being supported on the mounting portion 22 of the hanging member 20, and the first engaging portion 3a is suspended. It descends below the second locking portion B of the child 20. Then, when the pressing force by the first engaging portion 3a is released, the second engaging portion 7a of the existing roof panel 1A is restored, and the goby engaging portion 6a becomes the locking projection 27 of the suspender 20. It is securely engaged.

As shown in FIG. 5, the roof panel 1A
The recess 1b is provided in the flat portion 1a of the roof panel 1 in the vicinity of the first engaging portion 3a.
By providing the bent portions 4a and 8a between A and 1A separately from each other, the appearance is improved. Needless to say, the roof panels may be arranged so that there is almost no gap between adjacent roof panels. And the rainwater flowing on the roof surface is the roof panel 1A.

It is possible to reduce. In addition, since the interposition member is interposed between the one and the other rising portions, the one and the other rising portions of the suspension are fixedly supported, so that the supporting force of the suspension in the left-right direction is stabilized, and as a whole. Stabilize the supporting capacity of roof panels and suspensions.

(9) In the suspension, the first locking portion is composed of a rising portion and a portion in which the upper end of the rising portion is curved, and the second locking portion is formed by the locking projection, the mounting portion and the contact portion. By forming the contact support part, the first engagement part and the second engagement part of the roof panel support the goby engagement part or the engagement rising part so as not to move by the contact support part or the rising part. Therefore, when the roof panel is engaged with the suspension, the engagement is stable.

Further, by constructing the suspenders at the rising portions of the one and the other, it is possible to support the fixing of the roof panel, so that the roof panel can be more firmly engaged with the suspenders. Then, by having the rising fixing portion on the other rising portion, the bending step portion of the roof panel is formed by the bending fixing portion of one rising portion and the rising fixing portion of the other rising portion. Since it can be clamped and fixed, the roof panel can be extremely firmly engaged with the hanger.

(10) Since the roof panel is provided with the water blocking member which is an elastic member on the lower side of the first engaging portion, ultraviolet rays from the sun do not hit the waterproofing member and cause deterioration of the water blocking member. However, it has excellent waterproofness.

(11) The roof panel is laid horizontally and the second
Even if the rainwater is constantly accumulated in the drain formed by the engaging portion for a long time, the waterproof member provided on the lower side of the first engaging portion almost completely stops the water, so that ,
It does not give moisture to the edge portion, and it is possible to minimize the cause of deterioration of the roof panel.
