In the prior art shown in FIG. 10, the new roof needs to be fixed at the position of the hook bolt on the existing roof. Therefore, it was necessary to prepare a new roof according to the mounting dimensions of the existing roof. For example, if the distance between adjacent hook bolts in the girder direction of the roof does not match the dimensions of the new roof, it was necessary to drill holes in the existing roof in the mountainous area without hook bolts. In addition, if the distance between the hook bolts on the existing roof is large in the girder direction of the roof, there is a risk that the new roof will sink.

The present application is a structure in which a corrugated metal roofing material is mounted on a corrugated slate roof. Fixtures are attached to hook bolts that secure the corrugated slate roof. The auxiliary fixture has an upper surface and support legs extending outward and downward from both ends of the upper surface. The upper surface of this auxiliary fixture is arranged on the mountain portion of the corrugated slate roof, and the lower end of the support leg is placed on the valley portion of the corrugated slate roof. Then, the corrugated metal roofing material is fixed on the fixture and the auxiliary fixture by the fastener.

In the present application, the corrugated metal roofing material is fixed to the fixture at the position of the hook bolt on the corrugated slate roof, and is also fixed to the auxiliary fixture at the position without the hook bolt. Therefore, for example, even if the distance between adjacent hook bolts in the girder direction of the roof and the dimensions of the corrugated metal roofing material do not match, an auxiliary fixture is placed and used in the mountainous area where there is no hook bolt. It only needs to be drilled in the corrugated slate roof. Further, even when the separation distance between the hook bolts on the corrugated slate roof is large in the girder direction of the roof, the corrugated metal roofing material is supported by the auxiliary fixture, so that sinking is unlikely to occur.

In the corrugated slate roof S of this embodiment, the roofing material on which the mountain portion S1 and the valley portion S2 are formed is fixed to the roof base by using the hook bolt F. The hook bolt F projects toward the surface side from the mountain portion S1 of the corrugated slate roof S. This hook bolt F does not protrude from all the mountain portions S1 of the corrugated slate roof S. Therefore, there is also a mountain portion S1 in which the hook bolt F does not protrude.

The corrugated metal roofing material N of this embodiment is a roofing material on which a mountain portion N1 and a valley portion N2 are formed, and a fastener B is driven from the surface side of the mountain portion N1 to be fixed to the roof. It is desirable that the formation pitches of the peaks N1 and valleys N2 of the corrugated metal roofing material N of this embodiment are the same as the formation pitches of the peaks S1 and valleys S2 of the corrugated slate roof S.

A corrugated metal roofing material N on which a mountain portion N1 and a valley portion N2 are formed is attached to the fixture K of the present embodiment. As the fixture K of the present embodiment, a plurality of fixtures K are fixed to the hook bolts F on the corrugated slate roof S, the corrugated metal roofing material N is placed on the hook bolts F, and the fixture K from the surface side of the corrugated metal roofing material N.

Further, the plurality of groove lines K111 are also formed in a direction substantially parallel to the flow direction of the roof when the fixture K of the present embodiment is attached to the hook bolt F on the corrugated slate roof S.

When the hook bolt F is not vertical on the corrugated slate roof S, the fixture K of this embodiment is also attached in an inclined state. However, the fixture K of this embodiment has an upper surface formed in a curved shape that is convex upward. Since the structure is such that it is in contact with the back surface of the corrugated metal roofing material N, metal fitting marks do not appear on the corrugated metal roofing material N. It is desirable that the upwardly convex curvature is formed by adding the height dimension of the fixture K of the present embodiment to the radius of the mountain portion S1 of the corrugated slate roof S.

Further, when a fastener B such as a screw is driven into the fixture K from the surface side of the corrugated metal roofing material N, the tip of the fastener B is caught in the groove line K111, and the fixture B is placed on the fixture K. It does not slip and become difficult to stab. The number of grooves K111 and the distance between the groove lines K111 and K111 do not matter, but when the fastener B is driven, it does not slip on the corrugated metal roofing material mounting portion K11 over the range where the tip can hit. It is desirable that the groove lines K111 are formed at appropriate intervals.

The fixture K of this embodiment is composed of an upper member K1 and a lower member K2. Therefore, the mounting height of the corrugated metal roofing material N can be adjusted simply by changing either the upper member K1 or the lower member K2. Therefore, either the upper member K1 or the lower member K2 can be a common member regardless of the mounting height. Further, since the mounting height may be adjusted by either the upper member K1 or the lower member K2, the degree of freedom in design is high.

The upper member K1 of this embodiment has slide portions K13 and K13 at the lower ends of the leg portions K12 and K12. The upper member K1 of the present embodiment has an inner contact portion and an outer contact portion formed at the lower ends of the leg portions K12 and K12, and has a shape that holds the slidable portion K23 of the lower member K2 from the outside. It has become. Therefore, when the slide portion K13 and the slide portion K23 are engaged with each other, the vertical position and the girder position where the upper member is attached are fixed, and the structure is such that the upper member is slid only in the flow direction of the roof. Further, in this embodiment, since the sliding portion K23 of the lower member K2 is held from the outside, the sharp edge to the outside does not protrude, and the back surface of the corrugated metal roofing material N is covered. It has a structure that is not easily damaged.

The shape and structure of the slide portion K13 and the slide portion K23 of this embodiment are examples, and when the slide portion K13 and the slide portion K23 are engaged, the vertical position and the girder direction in which the upper member K1 is attached are attached. The structure may be such that the position in the roof is fixed and the structure is slid only in the flow direction of the roof.

The lower member K2 of this embodiment has a bottom surface K21 having a hook bolt fixing portion K211. In this embodiment, the bottom surface K21 is formed in a curved shape that is convex upward in accordance with the shape of the mountain portion S1 of the corrugated slate roof S.

Further, when the lower member K2 of the present embodiment is attached to the hook bolt F on the corrugated slate roof S, the hook bolt fixing portion K211 is formed by a notch from the end portion on the underwater side to the substantially central portion of the bottom side. .. The hook bolt fixing portion K211 is engaged with the hook bolt F on the corrugated slate roof S, and is used to fix the lower member K2 to the hook bolt F on the corrugated slate roof S. Therefore, the corrugated metal roofing material N can be attached without making a hole in the corrugated slate roof S.

In this embodiment, the water upper end portion of the lower member K2 is bent upward to form the impact receiving portion K24. The lower member K2 is fixed to the hook bolt F on the corrugated slate roof S by engaging the hook bolt fixing portion K211 with the hook bolt F on the corrugated slate roof S and striking the impact receiving portion K24 with a hammer or the like. Will be done.

The lower member K2 of this embodiment is formed with support portions K22 extending upward from a pair of both end edges of the bottom surface K21. The pair of both end edges of the bottom surface K21 are arranged so as to face the gable side of the roof when the corrugated metal roofing material mounting portion K11 of this embodiment is attached to the hook bolt F on the corrugated slate roof S. In this embodiment, the support portion K22 is formed above the pair of edge edges of the bottom surface K21, that is, from the pair of both end edges of the bottom surface K21 toward the corrugated metal roofing material N side. The mounting height of the corrugated metal roofing material N can be adjusted by the height dimension of the bearing portion K22, that is, by the lower member K2 of this embodiment.

The lower member K2 of this embodiment has a sliding portion K23 at the upper end of the bearing portion K22. In the present embodiment, the slide-to-slide portion K23 has a structure in which the upper end of the support portion K22 is bent outward and a notch is formed in the bent portion so that the edge protrudes both outside and inside. .. In this embodiment, the outer edge and the inner edge of the slide portion K23 are strongly contacted with the outer contact portion and the inner contact portion of the slide portion K13. Due to the structure, the upper member K1 and the lower member K2 are integrated so that once the slide portion K13 and the slide portion K23 are engaged with each other, they are difficult to come off. In this integration, no additional member such as a stud is required, and the cost can be kept low.

In the lower member K2 of this embodiment, a stop portion K231 is formed at one end of the slide-to-slide portion K23. The position where the underwater end edge of the slide portion K13 abuts on the stop portion K231 is an appropriate combination position of the upper member K1 and the lower member K2. Further, even when the sliding portion K13 and the sliding portion K23 are loosely engaged, the stopping portion K231 can prevent the upper member K1 from sliding down to the water side of the lower member K2.

The auxiliary fixture H of this embodiment has an upper surface H1 and support legs H12 extending outward and downward from both ends of the upper surface H1. A corrugated metal roofing material mounting portion H11 on which a plurality of groove lines H111 are formed is formed on the upper surface H1 of the auxiliary fixture H of this embodiment. The plurality of groove lines H111 are formed in a direction substantially parallel to the flow direction of the roof when the auxiliary fixture H of the present embodiment is installed on the corrugated slate roof S.

When the formation pitches of the peaks N1 and valleys N2 of the corrugated metal roofing material N and the formation pitches of the peaks N1 and valleys N2 of the corrugated slate roof S are the same, the auxiliary fixture H of this embodiment is It is installed when the overlapping portion of the corrugated metal roofing materials N and N hits the mountain portion S1 of the corrugated slate roof S without the hook bolt F. If the corrugated slate roof S and the corrugated metal roofing material N have the same girder dimensions, the overlapping portion between the corrugated metal roofing materials N and N always hits the mountain portion S1 where the hook bolt F of the corrugated slate roof S is located. .. However, when the girder dimensions of the corrugated slate roof S and the corrugated metal roofing material N are different, the overlapping portion of the corrugated metal roofing materials N and N does not necessarily hit the mountain portion S1 where the hook bolt F of the corrugated slate roof S is located. Not exclusively. Therefore, the auxiliary fixture H of the present embodiment is used to fix the overlapping portion of the adjacent corrugated metal roofing materials N and N.

In the auxiliary fixture H of the present embodiment, when the fastener B such as a screw is driven into the upper surface H11 of the auxiliary fixture H from the surface side of the corrugated metal roofing material N, the tip of the fastener B becomes the groove line H111. It has a structure that allows it to be caught, so that it does not slip on the auxiliary fixture H and become difficult to pierce. The number of grooves H111 and the distance between the groove lines H111 and H111 do not matter, but when the fastener B is driven, it does not slip on the corrugated metal roofing material mounting portion H11 over the range where the tip can hit. It is desirable that the groove lines H111 are formed at appropriate intervals.

It is desirable that the upper surface H1 of the auxiliary fixture H of this embodiment is formed in a curved shape that is convex upward. For example, one of the support legs H12 may be arranged on the overlapping portion of the corrugated slate roofs S / S, and the auxiliary fixture H may be installed in an inclined state. In that case, in the case of the auxiliary fixture H of this embodiment, since the upper surface H1 is formed in a curved shape that is convex upward, the structure is such that the upper surface H1 is in contact with the back surface of the corrugated metal roofing material N. There is. Therefore, metal fitting marks do not appear on the corrugated metal roofing material N. It is desirable that the upwardly convex curvature is formed by adding the height dimension of the auxiliary fixture H of this embodiment to the radius of the mountain portion S1 of the corrugated slate roof S.

In the auxiliary fixture H of this embodiment, the upper surface H1 is arranged on the mountain portion S1 of the corrugated slate roof S, and the lower ends of the support legs H12 and H12 are placed on the valley portion S2 of the corrugated slate roof S. At this time, a space is formed between the mountain portion S1 of the corrugated slate roof S and the auxiliary fixture H. Due to this space, the fastener B for fixing the corrugated metal roofing material N does not reach the corrugated slate roof S.

The lower end of the support leg H12 of this embodiment has a downwardly convex curved surface. With such a shape, the corrugated slate roof S is less likely to be damaged, and the lower end of the support leg H12 fits into the valley portion S2 of the corrugated slate roof S, so that the auxiliary fixture H of this embodiment is stable. It will be in the state of being placed on. Further, even when one of the support legs H12 is arranged on the overlapping portion of the corrugated slate roofs S and S and the auxiliary fixture H is installed in an inclined state, the lower end of the support leg H12 is similarly the corrugated slate roof S. It fits in the valley portion S2, and the auxiliary fixture H of this embodiment is placed in a stable state. Further, several groove lines may be formed on the lower end surface of the support leg H12 of this embodiment. The formation of several groove lines makes it difficult to slip on the corrugated slate roof S.

It is driven into and fixed.

At this time, when one corrugated metal roofing material N is fixed by the fixture K with two or more ridges, the auxiliary fixture H does not necessarily have to be fixed to the corrugated slate roof S. By fixing one corrugated metal roofing material N with two or more piles, the design strength equivalent to that of a normal mounting structure is secured, and the ends of adjacent corrugated metal roofing materials N and N are connected to each other. This is because it is connected by the fastener B on the fixture K or the auxiliary fixture H, so that there is no risk of it being turned up by wind or the like.

By making the structure in which the auxiliary fixture H is not fixed to the corrugated slate roof S in this way, the corrugated metal roofing material N can be attached without making a hole in the corrugated slate roof S.

Next, the mounting structure of the corrugated metal roofing material of the present application will be described. The fixture K of this embodiment is fixed to the hook bolt F on the corrugated slate roof S. Further, in the auxiliary fixture H of the present embodiment, the upper surface H1 is arranged on the mountain portion S1 of the corrugated slate roof S, and the lower end of the support leg H12 is placed on the valley portion S2 of the corrugated slate roof S. A mountain portion N1 of a corrugated metal roofing material N is attached to an upper surface H1 formed in a curved shape of the fixture K and the auxiliary fixture H of this embodiment. At this time, the portion where the corrugated metal roofing material N is in contact is not limited to the upper surface formed by the curvature of the fixture K of the present embodiment and the central portion of the upper surface H1 formed by the curvature of the auxiliary fixture H. Absent. The corrugated metal roofing material N may be in contact with a part of the curved upper surface of the fixture K and the curved upper surface H1 of the auxiliary fixture H of the present embodiment.
