DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a suspender, a roofing material, and a roofing material cap, each of which is made of a metal plate. In addition, the present invention relates to a roof structure having excellent waterproofness and excellent workability, in which fixing means such as fixing nails and screws are not exposed on the outer surface.

[0002]

2. Description of the Related Art There are various types of roof structures using a roof plate made of a metal plate. In recent years, a roof structure in which a recently roofed shape approximates a tiled state has been used in Japan. It is becoming more and more used because of its relationship with the sense of design. The roof structure whose roofing shape is similar to that of a tiled roof is corrugated at regular intervals parallel to the direction of rainwater flow from the ridge to the eaves, and is perpendicular to the direction of rainwater flow. Roof slabs with steps in the direction are placed on top of the base material, overlapping at the top and bottom and left and right ends, respectively, and fixed to the base material by penetrating fixing means such as nails and screws at the top of the roof slab material The structure to be made is common.

However, the conventional shingle structure employing such a fixing method has various disadvantages as listed below. The appearance is poor because fixing means such as nails and screws are exposed on the roof surface. The fixing means such as nails and screws that are exposed corrodes, so there is a problem in strength.In addition, when this fixing means is made of a material that generates rust, the rust stains the roof surface and the durability of the roof plate The appearance may be degraded, and there is a high risk of rainwater leaking from around holes drilled in the shingle to penetrate the fixing means. When a large number of tiles are formed by one metal plate in order to improve the efficiency of the roofing work, two or more workers are required for the positioning, and the number of locations where the fixing means is used increases.
The above disadvantages are promoted. Roof slabs that have a number of steps parallel to the eaves from the ridge and that are continuously formed across the entire width are damaged in the direction perpendicular to the direction from the ridge to the eaves. Even if a slight impact is applied from an out-of-plane direction, the roof slab material may be damaged at the step, and handling is very troublesome. Since the roof shingles are stacked one on top of the other, the roof shingles are sequentially shifted by the thickness of the roof shingles as the roofing progresses. Some skill is required. Since the edges of the roof sheet material are stacked one on top of the other and sequentially roofed, it must be sequentially roofed from one side, and it takes time to roof a large area. Since the roof shingles are stacked one on top of the other and the roof is sequentially roofed, rainwater intrusion cannot be prevented unless the overlapping portion is sufficiently removed, and if the overlapping portion is sufficiently removed, the material is uneconomical. is there. Since the roof shingles have a structure in which the ends are overlapped and sequentially roofed, adjacent roof shingles must be peeled off when performing partial repair, which is troublesome. Since the roof is united when it is roofed, the effects of thermal expansion and the like are accumulated, and there is a risk of deformation and rainwater leakage.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art and, despite the fact that the roofed shape is similar to a tiled state, a fixing nail or the like on the outer surface. It is an object of the present invention to provide a roof structure which is not exposed to a fixing means such as a screw or the like and is not a structure in which end portions of a roof slab material are overlapped with each other and are sequentially roofed.

[0005]

The inventors of the present invention have conducted various studies to solve the above-mentioned problems, and as a result, have a substantially U-shape with an open upper portion, and have the upper and lower ends on both sides of a roof plate material described later. The arc-shaped engaging pieces, which are formed in close contact with the arc-shaped engaging pieces, are respectively extended over the entire length. At the bottom, fixed at fixed intervals in parallel with the direction of rainwater flow by means of fixing means, then a mountain is formed in the center in the width direction, and at the part exposed to the roof surface when constructed, it is fixed in the direction of rainwater flow A circle continuously formed on a slightly upwardly inclined flat surface portion which is continuous on both sides of a portion exposed to the roof surface when the long roof sheet material having the step portions formed at intervals is exposed to the roof surface when constructed. A circle formed at the upper end on both sides of the suspender The springs are brought into close contact with each other by the spring action thereof, and then continuously on both sides of the central portion where the stepped portion is formed at the same interval as the stepped portion of the roof slab material, over the entire length on the inner surface side. An arcuate engagement piece formed at a side end of the roofing sheet material, which is formed at a side end of the roofing sheet material, which is continuous with the flat surface portion of the long roofing sheet material cap having a flat surface portion which is bent in a slightly upwardly inclined state. When the arc-shaped pressing pieces on both sides, which are formed by being curved upwardly over the entire length in a shape along the shape, are pressed in close contact with the arc-shaped engaging pieces of the roof plate material by the spring action, the roof was lifted. The shape is similar to the state of being tiled by the steps provided on the roof sheet material and the cap for the roof sheet material, fixing means such as fixing nails and screws are not exposed on the outer surface, and the ends of the roof sheet material are connected. Instead of roofing, push in from above and engage Since only,
The present invention was completed by investigating that a roof structure having good workability and excellent water resistance was obtained.

Further, when the arc-shaped pressing piece of the roof sheet material cap is pressed against the arc-shaped engaging piece of the roof sheet material by the spring action thereof, the arc-shaped pressing piece is continuously provided on both sides in the width direction of the roof sheet material cap. The inner surface side is slightly bent upwards over the entire length and is slightly upwardly continuous on both sides of the flat part that is bent and formed on the roof surface when the roof shingle is constructed. If a slight space portion is formed between the inclined flat surface portion and the space portion, the space portion functions as an equal pressure space, so that the arc-shaped pressing piece of the roof plate cap and the arc-shaped engagement of the roof plate material. It was also found that the amount of rainwater reaching the contact portion with the piece was reduced, and the water leakage resistance was further improved.

[0007] Further, the side ends of the arcuate engagement pieces formed on both sides of the roof slat protrude from the side edges of the arcuate engagement pieces formed on the upper ends on both sides of the suspender to open upward. If a groove is formed, rainwater that has invaded along the arc-shaped engaging pieces formed on both sides of the roof plate is guided to the eaves along the groove, It was also found that the water leakage was further improved.

Further, a rib is provided at the bottom of the suspender over the entire length so as to protrude upward with a fixing member such as a nail or a screw for fixing the suspender on the base material of the roof penetrating therethrough. If the overhanging portions are provided so as to protrude upward so that the head of the fixing means can be supported above the bottom portion, the protrusions enter along the arc-shaped engagement pieces formed on both sides of the roof plate material. It has also been found that water that has come and falls on the bottom of the suspension can be prevented from entering the base material of the roof from the through-hole portion of the fixing means, and the durability can be further improved.

[0013]

In order to construct the roof structure according to the present invention by using such components, first, the base material 1 of the roof is provided with a substantially rectangular opening having an upper part opened in parallel with the direction of rainwater flow from the ridge to the eaves. Arc-shaped engaging pieces 2a are formed over the entire length of the roof sheet material 4 at the upper ends on both sides thereof, and arc-shaped engaging pieces 4a formed on both sides of the roof plate 4 in close contact with each other. A fixing means 3 is provided at the bottom portion 2b of the elongated suspender 2 at a constant interval W at which the arc-shaped engaging piece 4a of the roof plate 4 just fits and engages with the arc-shaped engaging piece 2a of the suspender 2. Fix with. Next, a long roof plate material in which a mountain portion 4b is formed at the center in the width direction and a step portion 4c is formed at a constant interval L in a direction of rainwater flow in a portion exposed to the roof surface when being constructed. 4 at a constant interval W
Each of the suspension members 2 is fixedly engaged with the corresponding arcuate engagement piece 2a formed at the upper end of the suspension member 2 by the spring action thereof. After that, the step 4c of the roof plate 4
The stepped portion 5b is formed at the same interval L as that of the flat portion 5c which is formed by being bent in a state of being inclined upward slightly over the entire length on the inner surface side, continuously on both sides of the central portion where the stepped portion 5b is formed. For a long roof shingle which is curved upwardly over its entire length in a shape along the arcuate engagement piece 4a formed at the side end of the roof shingle 4 to form arc-shaped pressing pieces 5a on both sides. If the arc-shaped pressing piece 5a of the cap 5 is pressed in close contact with the arc-shaped engaging piece 4a of the roof sheet material 4 by its spring action, the roofed shape becomes the roof sheet material 4 and the roof sheet material cap 5, respectively. It is similar to the state of being tiled by the steps 4c and 5b provided in the roof, and the fixing means 3 such as fixing nails and screws are not exposed on the outer surface. Instead, just push the roof plate 4 and the roof plate cap 5 from above and engage them. Thus, a roof structure with good workability and excellent water resistance is completed.

As described above, the roof structure according to the present invention comprises the steps of first fixing the hanging members 2 on the base material 1 of the roof at a predetermined interval W in parallel with the direction of rainwater flow from the ridge to the eaves. The arcuate engagement piece 4a formed at the side end of the roof plate 4 is pushed into the arcuate engagement piece 2a formed at the upper end of the suspender 2 from above, and is engaged closely by the spring action. And the arc-shaped engaging piece of the roof plate 4
The step of pressing the arc-shaped pressing piece 5a of the roofing sheet material cap 5a into the upper part 4a from above and pressing it closely by the spring action thereof can be constituted, and these steps should be performed in this order. As long as you protect it, you can do it completely independently, and it is not necessary to overlap the ends of the roof sheet material like the conventional roof structure,
Workability is very good.

In the roof structure according to the present invention thus configured, rainwater sprayed on the roof surface and possibly leaking onto the base material 1 of the roof is as follows.
A flat surface formed by bending the roof plate material cap 5 in a state of being slightly upwardly inclined over the entire length on the inner surface side continuously on both sides of a portion exposed to the roof surface when the roof plate material cap 5 is constructed in the width direction. A flat part 4d that is slightly upward and continues on both sides of the part exposed to the roof surface when the part 5c and the roof plate 4 are constructed
The rainwater invades only the innermost portion between the flat portion 5c of the roof plate material cap 5 and the flat portion 4d of the roof plate material 4, and then the rainwater enters the circle of the roof plate material cap 5. Even if it penetrates upward due to the capillary action along the contact portion between the arc-shaped pressing piece 5a and the arc-shaped engaging piece 4a of the roof sheet material 4, the arc-shaped pressing piece 5a of the roof sheet material cap 5 and the arc-shaped piece of the roof sheet material 4 will not work. The portion in close contact with the engagement piece 4a is the arc-shaped engagement piece 4a of the roof plate 4.
, The capillarity is blocked at this portion, and the cap falls into the upper surface of the flat portion 4d of the roof plate material cap 5 and flows down toward the eaves. It does not reach the top of the piece 4a.

In particular, the roof sheet material cap 5 and the roof sheet material 4 are formed in such a shape that a slight space S is formed between the plane part 5c of the roof sheet material cap 5 and the plane part 4d of the roof sheet material 4. In this case, the space S forms an equal pressure space having the same pressure as that of the roof outer surface. Therefore, the space S is formed at the close contact portion between the arc-shaped pressing piece 5a of the roof-sheet material cap 5 and the arc-shaped engaging piece 4a of the roof-sheet material 4. The phenomenon of rainwater infiltration is greatly reduced.

Furthermore, if there is any construction defect, or if snow accumulated on the eaves in a cold region freezes, water accumulated on the ridge side from the frozen portion will cause the flat portion 5c of the roof plate cap 5 to be caught. And the flat plate portion 4d of the roof plate member 4 enters the inside of the roof plate member 4, and enters beyond the tops of the arc-shaped engaging pieces 4a formed on both sides of the roof plate member 4. At the side ends of the arcuate engagement pieces 4a formed at both sides, the arcuate engagement pieces formed at the upper ends on both sides of the suspension 2
In the case where a groove 4e protruding from the side edge of 2a and opening upward is formed, the water that has entered the groove 4e
Since the water flows down toward the eaves at 4e, the rainwater does not fall to the substantially U-shaped bottom 2b where the upper part of the suspension 2 is open.

If the groove-shaped portions 4e are not formed at the side ends of the arc-shaped engaging pieces 4a formed on both sides of the roof plate 4, the grooves 4e are formed on both sides of the roof plate 4. The water that has entered beyond the top of the arcuate engaging piece 4a that has entered the arcuate engaging piece 4a from the top of the arcuate engaging piece 4a of the roof plate 4
Even if it falls on the bottom 2b, which has a substantially U-shape with the upper part of the suspender 2 open along 4a, fixing of the nails or screws for fixing the suspender 2 on the base material 1 of the roof In order to prevent the means 3 from penetrating into the base material 1 of the roof from the penetrated hole,
The bottom 2b of the suspension 2 is provided with a rib 2c projecting upward through a portion through which the fixing means 3 for fixing the suspension 2 is fixed on the base material 1 of the roof. The water resistance can be further improved by providing an overhang portion 2d protruding upward so as to support the head of the fixing means 3 for fixing the suspension 2 above the bottom portion 2b.

[0019]

As described in detail above, the roof structure according to the present invention comprises a step of fixing suspension members on the base material of the roof at regular intervals in parallel with the flow direction of rainwater from the ridge to the eaves by fixing means. A step of pushing the arcuate engagement pieces formed on both sides of the roofing plate material into the arcuate engagement pieces formed on the upper ends on both sides of the suspender from above, and bringing the arcuate engagement pieces into close contact by the spring action thereof; A step of pressing an arc-shaped pressing piece of the roofing sheet cap into the arc-shaped engaging piece of the roofing sheet material from above and pressing the same in close contact by the spring action thereof. If you follow this order, you can do it completely independently, not only do you need to overlap the edges of the roof sheet material like the conventional roof structure, but also Repeat Since nor requires skill to align linearly with eaves went shifted sequentially by the thickness portion of the roof plate according proceeds roofing as follows thatched by going structure, workability is extremely good.

In the above three steps, a fixing means such as a nail or a screw is used only for fixing the hanging member on the base material of the first roof, and the nail is attached to the roof surface in a completed state. Since the fixing means such as screws and screws are not exposed, not only the appearance is good, but also the fixing means corrodes, causing problems in strength and rust generated from the fixing means stains the roof surface or penetrates the fixing means Therefore, there is no danger of rainwater leaking into the base material of the roof from around the hole drilled. If a system is used to build a building using standardized members, such as a prefabricated house, the work of fixing the hangers at regular intervals on the base material of the roof must also be performed at the factory in advance. If done, it is also possible to perform the roofing work without using any fixing means on site.

Further, in each of the above three steps, the roofing work can be performed in a short time by a small number of workers by using long members. It is divided into a roof plate cap and these members do not have a step on both sides thereof. In addition, the roof plate material has an arc-shaped engaging piece, and the roof plate cap has an arc shape. Since the pressing pieces are formed over the entire length, they are reinforced in the longitudinal direction, so that these members are not damaged.

Also, since the roof shingle and the roof shingle cap constituting the roof surface are not fixed by the fixing means, the roof shingle and the roof shingle cap are removed from the roof shingle and the new roof shingle are removed when performing a partial repair. It is possible to easily replace a roofing material or a roofing material cap which needs to be replaced or repaired with a roofing material or a roofing material cap.

Even if the roof sheet material and the roof sheet material cap constituting the roof surface are not fixed by the fixing means as described above, even if the roof sheet material is lifted by negative pressure or the like and tends to come off the roof surface. When the roof shingle is constructed, the flat part continuous on both sides of the part exposed to the roof surface presses the flat part continuous on the inner surface on both sides in the width direction of the roof shingle cap. Since the arc-shaped pressing piece of the roof cap presses the arc-shaped engaging piece of the roof slat more firmly, the phenomenon that the roof shingle is removed from the roof surface together with the roof slat cap does not occur.

Since the edge of the adjacent roof plate is cut off at the position of the suspender, the plate elongation due to thermal expansion or the like is not absorbed by the arcuate engagement piece and is not deformed. There is no danger.

When the roof plate is constructed, the flat portion formed on the inner surface side and bent slightly upward over the entire length continuously on both sides in the width direction of the roof plate material cap and the roof plate material are applied. If a slight space portion is formed between both sides of the portion exposed to the roof surface and a plane portion inclined slightly upward continuously to form a constant pressure space, the water leakage resistance is further improved.

Also, the side ends of the arcuate engaging pieces formed on both sides of the roof plate project from the side edges of the arcuate engaging pieces formed on the upper ends on both sides of the suspender and open upward. Or a rib protruding upward across a portion through which a fixing means for fixing the suspender on the base material of the roof penetrates is provided at the bottom of the suspender. If the overhang is provided so that the head of the roof plate can be supported above the bottom, water that has invaded beyond the tops of the arcuate engagement pieces formed on both sides of the roof shingle is provided. Can be prevented from penetrating into the base material of the roof from the hole penetrated by the fixing means at the bottom of the suspender even if it falls on the bottom of a substantially U-shape where the upper part of the suspender is open. The water resistance is further improved.

The industrial value of the roof structure according to the present invention having various effects as described above is very large.
