Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a through-hanging member for a thatched roof that extends from the ridge side to the eaves side of the roof, and a thatched roof structure that uses the through-hanging member. is there.

[0002]

2. Description of the Related Art In the technique of roofing a roofing board for side roofs from the eaves side to the ridge side, in order to prevent the roofing board from being damaged,
Since a large-scale scaffold is required to be assembled, there is a problem in that the construction cost is high, and there is a problem in that workability is deteriorated due to the existence of the scaffold.

Therefore, in recent years, a technique has been developed in which a side-roofing roofing board is roofed from the ridge side to the eaves side, and various hanging structures used for that purpose have been proposed. There is.

As one of the suspenders, as shown in FIG. 6, a supporting portion 34 of an eaves side underlayer material 33 is formed on a mounting plate 32 fixed on a supporting member 31, and the supporting plate 34 is mounted on the ridge side of the mounting plate 32. A rising portion 35 is erected at the end of the ridge, and a supporting step portion 36 of the ridge-side base material 33 bent toward the eaves is formed at the upper end of the rising portion 35, and a receiving plate 37 is provided on the eaves side of the supporting step portion 36. Stand up,
There is one in which a folding back locking plate 38 to the eaves side is formed at the upper end of the receiving plate 37 and an eaves side roof plate hooking portion 39 is formed at the eaves side end of the locking plate 38 (Japanese Patent Publication No. 3-3386
No. 9).

When the horizontal thatched face plate 41 is roofed from the ridge side to the eaves side using this suspension 40, the hooking part 39 of the suspension 40 is attached to the eaves side engaging part 42 of the face plate 41 on the ridge side. The fitting plate 32 of this suspension 40 is fitted and fixed on the support member 31, then the ridge side of the eaves-side face plate 41 is inserted into the suspension, and the joint portion 43 of this face plate 41 is hooked. The procedure for locking to 39 is taken.

[0006]

By the way, in the suspension 40 having the above-mentioned structure, the face plate 41 on the ridge side only rides on the locking plate 38 of the suspension 40, and the face plate 41 on the eaves side. In that case, it is engaged and connected to the face plate 41 on the ridge side, and the joint portion 43 is only slightly locked to the hook portion 39 of the suspension 40, and when wind pressure is applied, Even if the wind pressure is not so strong, there is a problem in that the face plates 41, 41 that are engaged and connected are lifted to cause abnormal noise and rainwater enters the inside.

Further, since the suspension 40 is a width ridge, it is fixed to a support member 31 such as a metal rafter arranged at a predetermined pitch, and the face plates 41, 41 are attached to the suspension 40.
In the case where the face plates 41, 41 are attached, there is a concern that the face plates 41, 41 may be flexibly deformed between the arrangement portions of the suspension 40 when a large load such as snow is applied to the joint portion of the face plates 41, 41.

The present invention has been made in view of the above circumstances, and an object thereof is to reliably prevent lifting of a side-roofing roof panel when it is subjected to wind pressure and to receive a large load. Even if it is, flexural deformation of the roof plate is effectively prevented, and even if rainwater enters the inside, a through-hanger that reliably prevents the inflowing rainwater from flowing down onto the support member, The point is to provide a horizontal thatched roof structure using this through suspension.

[0009]

[Means for Solving the Problems] That is, according to the present invention, as a hanging member for a thatched roof, which is a roofing roof that extends from the ridge side of the roof to the eaves side, it is provided with end portions which are adjacent to each other and are butted against each other. Specifically, the board structure is fixed on the supporting member in a state where the adjacent ends are abutted against each other, and the water that bends upward from the eaves side end of the board part is used. Standing part for receiving, rising part bent upward from the ridge-side end of the board part, folded part bent from the upper end of this rising part to the eaves side, and eaves side end of this folded part Part for bending the eaves side roof plate, which is bent toward the ridge downward from the section, a second folded part that is bent from the lower end of the inclined part to the eaves side, and an end part of the folded part on the eaves side. Of the erected part that bends upward from the The holding part is integrally formed by one metal plate, and the standing part for receiving water is bent at the eaves side end of the base plate part, while the ridge side edge of the ridge side roof plate support part is formed. Is characterized in that it is formed so as to face the width of the gutter formed by the inclined surface portion, the second folded portion and the upright portion (claim 1).

Preferably, the water-stop ridge is bulged in the ridge side of the water receiving upright portion of the base plate portion (claim 2).

When constructing a thatched roof, a downwardly bent hanging part is continuously provided at the eave side end of the thatched roofing plate, and a lateral thatched roofing plate extends from the lower end of this hanging part toward the ridge. The rise prevention part of the horizontal roofing board is connected to form a recess on the lower surface of the eaves side of the thatched roofing board. That is, the locking portion that bends from the upper end to the eaves side is continuously provided.

Then, the above-mentioned hanging gutter component parts (sloping surface part, second folding part and standing part) of the hanging part are fitted into recesses formed in the lower surface part of the eaves side of the thatched roof plate. When the through suspension is pulled up to the eaves side by using the standing part for receiving water as necessary, and the adjacent ends of the through suspension are abutted against each other, the through suspension is suspended. The child is fixed on the support member, and then the ridge side of the eaves side thatched roof board is inserted between the board part of the through suspension and the rising prevention part of the ridge side roof board, The locking part continuously provided on the ridge side of the roof plate is locked to the slope part of the suspension through the locking member, and the side thatched roof plate is roofed from the ridge side to the eaves side (claim 3).

In the side-roof roof structure using the through-hangers described above, the concave portion formed on the eaves side of the ridge-side roof plate is fitted and held in the trough component of the through-hanger, and the ridge side of the eaves-side roof plate. The side-roof roof plate is retained on the through-hanger in a state in which the locking portion formed on the side is locked to the slope portion of the through-hanger and hardly moves up and down. Even if it receives a strong wind pressure, it does not float up, and the generation of abnormal noise due to the uplift is effectively prevented.

Further, since the sling has a structure of a long through sling, the supporting strength of the roof plate by this through sling is high. Therefore, for example, a snow cover is formed at the joint between the roof slats. Even if a large load is applied due to, for example, flexural deformation of the roof plate is effectively prevented.

In addition, rainwater is blown through between the eaves side of the ridge side roof plate and the ridge side of the eaves side roof plate, and this is between the locking part of the eaves side roof plate and the slope part of the through suspension. Through the gap,
Even if the water flows around to the rising portion side of the through suspension, the water flows to the substrate portion side of the through suspension and is received by the standing portion for receiving water, and also according to claim 2. As described above, when the swelling portion for stopping water is swollen, the swelling portion is also received by the swelling portion, and the invading rainwater does not drop on the support member.

On the other hand, the above-mentioned rainwater blown in is between the second folded-back portion of the through suspension member and the rising prevention portion of the ridge-side roof plate, and between the hanging portion of the through suspension member and the upright portion of the ridge-side roof plate. Even if it wraps around the support part side of the through suspension through the gap between the support and the ridge side of the through suspension, the ridge-side end edge of this support part is provided with the slope portion of the through suspension, the second folded portion, and the upright portion. Since it is exposed within the width of the gutter formed by and, the water that has spilled to the support part side due to the above-mentioned capillary phenomenon falls into the trough of the through suspension, and this invading rainwater also falls on the support member. It doesn't fall to.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a cross-sectional view of a joint portion of side-roofing roofing plates 2 and 2 with a through suspension 1.

A second folded portion 10 bent from the lower end of the sloped portion 9 to the eaves side, a standing portion 11 bent upward from the end of the folded portion 10 on the eaves side, and an upper end portion of the standing portion 11. From the ridge side to the ridge side, and the ridge-side edge a of the support portion 12 of the ridge-side roof plate 2 is formed.
Is configured so as to face the width of the gutter A formed by the sloped portion 9, the second folded portion 10 and the upright portion 11.

The lateral thatched roof plate 2 is a long bent product of, for example, a coated steel plate, and a downwardly curved hanging portion 21 is continuously provided at the eave side end of the lateral thatched roof plate 2. A slope portion 22 is continuously provided at the lower end of the hanging portion 21, and a rising prevention portion 23 of the side thatched roof plate 2 is continuously provided on the ridge side so as to be connected to the slope portion 22. While forming a recess B on the lower surface of the eaves, the ridge-side end of the thatched roof plate 2 is provided with a standing portion 24 that is bent upward in a dogleg shape. An engaging portion 25 that bends to the eaves side is continuously provided from the upper end of the.

It should be noted that the floating prevention portion 23 of the roof plate 2 and the end portions 26 and 27 of the locking portion 25 are bent so that the respective end faces are not directly exposed to the weather.
In addition, a backup material 28 such as a wood wool cement plate is provided on the lower surface of the roof board 2 to improve the heat insulation and sound insulation of the roof.

When constructing a side-roof roof using the above-mentioned through suspension 1 and the thatched roofing board 2, as shown in FIG. 3, a part of the trough A of the through suspension 1, that is, a slope portion 9 and 2
The part of the gutter by the folded-back part 10 and the standing part 11 of
The through-hook 1 is pulled to the eaves side by fitting and holding it in the recess B on the eaves side of the thatched roof board 2 and utilizing the standing portion 5 for receiving water. The through suspension 1 is fixed on the support member 3 in a state where the adjacent ends are abutted against each other.

In this embodiment, the base plate 4 of the through suspension 1 is mounted between the standing portion 5 for receiving the water and the raised portion 6 by using the screw c with the packing b for stopping water. Although it is fixed to the support member 3, fixing means such as a rivet can be arbitrarily selected.

Next, as shown by a phantom line in FIG. 3, the ridge side of the eaves side thatched roof plate 2 is placed between the board portion 4 of the through suspension 1 and the floating prevention portion 23 of the ridge side roof plate 2. , And lower the eaves side of the eaves side roof board 2 to the support member 3 side,
The locking portion 25 on the ridge side of the eaves side roof board 2 is locked to the sloped portion 9 of the suspension 1 through.

After that, the structure of the trough of the through suspension 1 is fitted and held in the concave portion B of the roof plate 2 on the eave side, and the through suspension 1 is pulled toward the eave by the standing portion 5 for receiving water. , And in a state where the adjacent ends of the through suspension 1 are butted against each other,
The through suspension 1 is fixed on the support member 3, and the eaves side roof plate 2
The locking part 25 of the above is repeatedly locked through the sloped part 9 of the suspension 1, and the side thatched roof plate 2 is roofed from the ridge side to the eaves side.

In the side-roof roof structure using the through-hanger 1 described above, the recess B on the eaves side of the side-roofing roofing plate 2 is fitted and held in the trough component of the through-hanger 1 and the side-roof. The locking part 25 on the ridge side of the plate 2 is locked to the slanted surface part 9 of the through suspension 1 so that the side-roofed roof plate 2 is held by the through suspension 1 with almost no vertical movement. Therefore, the lateral thatched roof plate 2 does not float up even when a strong wind pressure is applied, and the generation of abnormal noise due to the floatation is effectively prevented.

Further, because of the structure of the through suspension 1,
The supporting strength of the roof plate 2 by the through suspension 1 becomes high,
From this, even if a large load such as snow is applied to the joint between the roof plates 2 and 2, the flexural deformation of the roof plate 2 is effectively prevented.

When it rains, rainwater that flows by licking the eave-side hanging part 21 of the thatched roof plate 2 is drained before reaching the slope portion 9, and the eave-sided thatch. Although it drips onto the roof board 2, rainwater may blow between the eaves side of the ridge side roof board 2 and the ridge side of the eaves side roof board 2 when it rains with wind. It is considered that rainwater may flow around the rising portion 7 side of the through suspension 1 through the gap d between the sloped portion 9 of the through suspension 1 and the locking portion 25 of the eaves side roof plate 2 that is locked to this. To be

However, this water is passed through the substrate portion 4 of the through suspension 1.
It flows to the side and is received by the raised portion 6 that bulges on the substrate portion 4. Even if the raised portion 6 overflows, it is received by the standing portion 5 for receiving water, and the rainwater that has invaded. Does not fall on the support member 3.

Alternatively, the rainwater blown between the eaves side of the ridge side roof plate 2 and the ridge side of the eaves side roof plate 2 is the second of the through suspension 1
Through the gap between the folded-back portion 10 and the rising prevention portion of the ridge-side roof plate 2 and into the gap between the upright portion 11 of the through suspension 1 and the hanging portion 21 of the ridge-side roof plate 2, and due to the capillary phenomenon. Even if it wraps around the supporting portion 12 side of the through suspension 1, since the ridge-side end edge a of this supporting portion 12 faces the width of the gutter A formed in the through suspension 1, Part 1
The water that has spilled around to the second side will fall into the gutter A, and the rainwater that has entered does not fall onto the support member 3.

A lateral thatched roof panel 2 according to another embodiment is shown in FIGS. In the lateral thatched roof plate 2 shown in FIG. 4, a part of the rising prevention portion 23 of the roof plate 2 is bent downward, and the bent portion is used as the draining portion 29.
In the side-roof roofing board 2 shown in (1), a part of the floating prevention portion 23 of the roofing board 2 is bulged downward, and the bulging portion is formed in the draining portion 29.

In the various embodiments described above, the fixing means for fixing the screw c is adopted as the fixing means for the through suspension 1 with respect to the supporting member 3, and the packing b for stopping water is provided. Therefore, water leakage through this screw c does not occur.

On the other hand, the provision of the above-mentioned raised portion 6 is suitable not only for improving the waterproofness but also for increasing the strength of the through suspension 1 together with the standing portion 5 for receiving water. It is needless to say that, if the fixing means having such a water stopping function is provided, it is not always necessary to provide the raised portion 6 on the substrate portion 4, and the raised portion 6 can be omitted and implemented. Therefore, in the embodiment shown in FIGS. 4 and 5, the raised portion 6 is omitted.
