Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal joint structure for a thatched roof.

[0002]

2. Description of the Related Art In the so-called side-roofed roof, a plurality of roofing boards are continuously arranged in a direction orthogonal to the water gradient direction of the roof (hereinafter referred to as "horizontal direction"). As the joint structure, there are (1) a type in which the end of one roof plate is overlapped with the end of the other roof plate, and (2) a type in which two adjacent roof plates are horizontally connected by a joint metal fitting. .

As a lateral joint structure of the type (2), there is, for example, JP-A-6-10452.
FIG. 6 shows an example of this lateral joint structure. Reference numeral 2 in FIG. 6 is a joint metal fitting, which is arranged between the two roof plates 1 and 1 which are horizontally adjacent to each other. This joint fitting 2
Is a water receiving part 3 arranged below the roof plates 1 and 1
And a cover part 4 for waterproofing by covering the connection part between the roof plates 1 and 1 from the upper side. And
Insertion grooves 3a, 3 formed on the left and right sides of the water receiving portion 3 in FIG.
By inserting the roof plates 1 and 1 into a, the horizontally adjacent roof plates 1 and 1 are horizontally connected.

However, in the horizontal joint structure as described above, it is troublesome to assemble the joint metal fitting 2 consisting of two parts on site, and therefore the workability is unsatisfactory. FIG. 7 shows an example of a lateral joint structure developed in view of the above problems. In the horizontal joint structure shown in FIG. 7, horizontally adjacent roof plates 11, 11 are connected via joint fittings 12. FIG. 8 is a sectional view showing this lateral joint structure. In FIG. 8, the joint metal fitting 12 is formed by bending a single metal plate, and is provided below the connecting portion and a center portion 12a that covers the connecting portions between the roof plates 11 and 11 from above. The water receiving parts 12b and 12b are provided. Further, a sealing material 13 is attached to the lower side of both water receiving portions 12b, 12b to prevent water from leaking to the base material 14. Center part 1
An insertion groove 12c into which the roof plate 11 is inserted is formed between 2a and the water receiving portion 12b. This insertion groove 12c
Has a structure in which the inserted roof plate 11 is sandwiched and stably supported. The water receiving portions 12b and 12b extend from the center portion 12a to both sides in the horizontal direction, and are located below the roof plates 11 and 11, respectively. Each water receiver 1
A folded-back portion 12d that is folded back upward is formed at the tips of 2b and 12b. Further, as shown in FIG. 7, a folded portion 12e is also formed at the upper end of the water receiving portion 12b in the water gradient direction. By these folded portions 12d and 12e,
Even if rainwater enters through the gap between the roof plates 11 and 11 and the center portion 12a, the water receiving portions 12b and 12
Since b becomes a saucer and receives rainwater, base material 1
Rainwater is prevented from entering the 4th grade. Water receiver 12
The rainwater received by b flows down in the direction of the water gradient and is discharged.

[0005]

However, in the lateral joint structure as described above, it is necessary to use the joint metal fitting 12 having a size and shape that match the size of the roof plate 11, so that the size of the roof plate 11 is changed. In that case, it is necessary to prepare a joint fitting 12 having a shape that can cope with each case, and there is a disadvantage that the cost cannot be sufficiently reduced in the end. For example, if the size of the center portion 12a in the water gradient direction is adjusted to correspond to the working width of the roof plate 11 (region L in FIG. 7), the size of the water receiving portion 12b in the water gradient direction is equal to the water receiving portion 12b. Since it is necessary to always make the joint metal 12 longer than that,
The cost of forming the joint fitting 12 increases. Further, the joint fitting 12 can absorb a dimensional change by deforming the center portion 12a like a spring against deformation and displacement such as expansion and contraction of the roof plate 11 due to difference in temperature and temperature, strong wind, snow, etc. However, the amount of deformation and displacement of each roof plate 11 on the roof is not uniform, and the roof plate 1
If the deformation (or displacement) of No. 1 is locally concentrated, the joint fitting 12 may be displaced with respect to the roof plate 11 or may be detached from the roof plate 11.

Further, in view of preventing roof corrosion and the like, in order to reliably prevent leakage of water from the water receiving portion 12b, the folded portion 1
It is necessary to precisely form the 2d and 12e so that water does not leak from between the connecting portions, which is troublesome to form. Further, as shown in FIG. 8, in this joint fitting 12, a gap is easily formed between the water receiving portions 12b, 12b formed on both sides of the center portion 12a, and as shown in FIG. , Both water receiving part 12
Since there is a portion where the boundary between b and 12b is not covered by the center portion 12a, there is a space between the water receiving portions 12b and 12b and the folded portions 12e and 12 of the water receiving portions 12b and 12b.
It is necessary to precisely form the space between the e to prevent water leakage. In view of this, it is conceivable to frequently use the sealing material 13 to prevent water leakage, but since the number of parts increases, it takes more time to form the joint metal fitting 12 and the cost can be reduced. Disappear. Moreover, when the joint fitting 12 is deformed or displaced due to the deformation or displacement of the roof plate 11, the sealing material 13 is likely to be peeled off, and the sealing effect is not sufficiently exerted.
There is also a concern that the meaning of installing 3 will be lost.

The present invention has been made in view of the above-mentioned problems. (A) A pair of leg portions formed on the insertion cover portion is inserted between bearing portions protruding from the water receiving portion, By adopting joint fittings that are pressed against each other with a biasing force in the direction of separation, even if deformation or displacement such as expansion and contraction occurs on the roof plate due to cold and heat etc., the mounting state of the joint fittings is maintained stable , (B) Since the joint fitting is composed of two parts, the insertion cover part and the water receiving part, it is possible to easily cope with the shape of the roof plate and reduce the cost only by adjusting the shape of the insertion cover part. c) A horizontal joint structure for a thatched roof, which provides high waterproofness due to the rising part that extends continuously over almost the entire circumference of the water receiving part except the lower end in the water gradient direction, and can reliably prevent corrosion of the roof due to flooding. Provide For the purpose of Rukoto.

[0008]

According to a first aspect of the present invention, a horizontal joint for a thatched roof is formed by horizontally connecting, via joint fittings, roof plates connected in a direction orthogonal to the water gradient direction of the roof. A structure, wherein the joint fitting is

In this horizontal joint structure for a thatched roof, the insertion cover portion acts like a spring and elastically deforms to absorb the deformation and displacement of the roof plate due to the difference in temperature and temperature. At this time, the insertion cover portion presses both legs against the bearing portions of the water receiving portion so as to press them, so that they cannot be easily separated from the water receiving portion even when a considerably strong external force acts. Therefore, the insertion cover portion is unlikely to be displaced or come off from the roof plate, and the mounted state is stable. If the displacement force acting on the insertion cover is released,
The insertion cover part will return to its original shape due to the elastic force of the insertion cover part or the leg part. There is no concern that the insertion cover part will be displaced with respect to the water receiving part, and the insertion cover part will surely return to the original mounting state.
Further, the size of the roof plate can be dealt with by adjusting the size of the insertion cover part, and the water receiving part does not need to be adjusted in size, so that high versatility with respect to the size of the roof plate can be obtained.
In addition, the center part is assembled, ensuring upward bending
Since it has a different shape, the pressure on the rising part of both legs is

It is possible to prevent disengagement and abnormal mounting condition.

According to a second aspect of the present invention, the water receiving portion is one component formed by processing a metal plate, and the pressure bearing portion is a rising portion formed by forming an edge portion of the water receiving portion to stand up. If the rising portion is configured to continuously extend over substantially the entire circumference of the water receiving portion except the lower end in the water gradient direction, leakage from the water receiving portion to the outside can be reliably prevented by the rising portion. .

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a horizontal joint structure for a thatched roof of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 is a cross-sectional perspective view showing a horizontal joint structure of a horizontal thatched roof according to this embodiment. In FIG. 1, reference numeral 20
Is a roof plate, 21 is a joint metal fitting, and the roof boards 20, 20 continuously provided in a direction orthogonal to the water gradient direction of the roof (hereinafter referred to as “horizontal direction”) are horizontally connected via a joint metal fitting 21. The joint fitting 21 is a water receiving portion 2 arranged below the horizontal connecting portions of the two roof plates 20, 20 which are horizontally connected.
2 and an insertion cover portion 23 that is mounted on the upper side of the water receiving portion 22 and covers the lateral connection portion from the upper side to prevent rainwater from entering.

The insertion cover portion 23 is formed by bending a single metal plate, and is provided between the roof plates 20 and 20 which are horizontally connected to each other, and a center portion 23a disposed between and above the roof plates 20, and the center portion 23a. Legs 2 that are bent into a shape having roof plate insertion grooves 23b into which the roof plate 20 is inserted
3c and. The roof plate insertion groove 23b holds the inserted roof plate 20 and provides pull-out resistance.
FIG. 2 is an exploded perspective view showing the joint fitting 21.
As shown in FIG. 2, from the lower end of the center portion 23a in the water gradient direction (on the left front side of the paper surface in FIG. 2), an engaging bent portion 23d engaged with the lower end of the water receiving portion 22 in the water gradient direction is provided. ing. The roof plate insertion groove 23b corresponds to the insertion groove according to claim 1. As shown in FIG. 1, the roof plate 20 has a structure in which a heat insulating sheet 20b made of a resin foam or the like and having a thickness of several mm is attached to the lower surface of a steel plate 20a for a roof plate. When it is inserted into the plate insertion groove 23b, sufficient waterproofness can be obtained.

As shown in FIG. 2, the water receiving portion 22 is
A single metal plate is bent to form an elongated plate.
A plurality of stopper projections 22a having a shape projecting upward (upward in FIG. 2) are formed in the central portion in the width direction (direction perpendicular to the longitudinal direction) of the water receiving portion 22. Water receiver 2
A curved portion 22b is formed at the upper end (right rear side in FIG. 2) in the water gradient direction. At the lower end of the water receiving portion 22 in the water gradient direction (on the left front side in FIG. 2), there is provided a positioning folding portion 22c for positioning the roof plate 20 inserted into the roof plate insertion groove 23b of the leg portion 23c. A flange-shaped rising portion 22d is provided so as to project upward on almost the entire circumference of the outer peripheral portion of the water receiving portion 22 excluding the lower end in the water gradient direction. Since this rising portion 22d does not form only the lower end of the water receiving portion 22 in the water gradient direction, the water that has fallen into the water receiving portion 22 is discharged according to the water gradient so as to flow down from the vicinity of the positioning folding portion 22c, and the water is discharged. It falls on another roof plate (not shown) that is connected to the lower side in the gradient direction. The rising portion 22
d can be easily formed by a roll molding machine or the like, and since it extends continuously over substantially the entire circumference of the water receiving portion 22, high waterproofness can be secured. The rising portion 22d also has a function of supporting the biasing force acting from both legs 23c and 23c of the insertion cover portion 23 attached to the water receiving portion 22, and corresponds to the pressure supporting portion according to claim 1.

Since the stopper protrusion 22a is a ridge extending along the longitudinal direction of the water receiving portion 22, it also contributes to the reinforcement of the water receiving portion 22. Then, as shown in FIG. 1, when the insertion cover portion 23 is mounted on the water receiving portion 22, the positioning curved portions 23e formed on the both leg portions 23c, 23c of the insertion cover portion 23 and the both leg portions 23c, 23c. The clearances 23f existing therebetween come into contact with the stopper protrusions 22a, respectively, whereby the positioning is stably performed.

In the disassembled state shown in FIG. 2, the separation distance between the positioning curved portions 23e, 23e of the two leg portions 23c, 23c is determined by the distance between the stopper protrusions 22a, 22a abutting on the positioning curved portions 23e, 23e. It is slightly longer than the distance, and in the assembled state shown in FIG.
c and 23c are inserted into the water receiving portion 22 such that they are elastically deformed by bringing them closer to each other. Therefore, the tips of the leg portions 23c, 23c inserted into the water receiving portion 22 are both biased by the elasticity of the insertion cover portion 23 or the leg portions 23c themselves, and are pressed against the rising portion 22d with a biasing force. The insertion cover part 23 is elastically deformed by the center part 23a shown by the phantom line in FIG. 1 against the external force applied by the weather such as strong wind and snow, or the deformation or displacement of the roof plate 20 caused by the difference in temperature. Correspondingly, at this time, by the biasing force of the leg portion 23c to the rising portion 22d, the insertion cover portion 2 to the water receiving portion 22
The mounted state of No. 3 is stably maintained, and even when the insertion cover 23 is repeatedly deformed or displaced or returned to its original shape, the mounted state can be stably maintained.

FIG. 3 shows a vertical cross section along the direction of the water gradient of the horizontal joint structure for the thatched roof. In FIG. 3, the roof plate 20 includes a lower end turnback portion 20c projecting downward from a lower end in the water gradient direction (upper right in FIG. 3), an engaging turnback portion 20d projecting upward from an upper end in the water gradient direction, and the engaging member. It is provided with a fixing flange 20e formed further upward in the water gradient direction from the combined turn-back portion 20d. Lower end folded portion 22
The c is fitted between the positioning folded-back portion 22c of the water receiving portion 22 and the engaging bent portion 23d of the insertion cover portion 23 in a retractable manner. Therefore, the roof plate 20 is stably supported at a predetermined position at the same time when it is inserted into the roof plate insertion groove 23b.

On the other hand, the engaging bent portion 20d is engaged with an engaging bent portion 24a projecting from the lower end of another roof plate 24 which is continuously provided on the upper side of the roof plate 20 in the water gradient direction. The roof plate 20 is fixed to a target position by fixing the fixing flange 20e to the base material 26 with nails 25 or the like. At this time, since the fixing flange 20e is in a state of being supported on the rising portion 22d near the curved portion 22b, the roof plate 20 is in a state of being stably supported at both upper and lower ends in the water gradient direction, and strong wind or the like can be obtained. It is designed not to be easily displaced by external force.

FIG. 3 shows the assembled state when the gradient is 2/10 or more. When the gradient is less than this, as shown in FIG. 4, the packing 27 and the clip 28 are shown.
By using together, the fixing flange 20e can be fixed to the base material 26.

As described above, according to the horizontal joint structure of the thatched roof, the roof plate 20 is stably supported, and even when the roof plate 20 is deformed or displaced due to a difference in temperature between warm and cold. The deformation amount and the displacement amount can be absorbed by the deformation of the insertion cover portion 23. Moreover, the insertion cover portion 23 is inserted into the water receiving portion 22 in a state where both the leg portions 23c, 23c are biased, so that even if the insertion cover portion 23 is deformed by the deformation or displacement of the roof plate 20, the roof plates 20, 2,
There is no concern that it will deviate from 0 or that the wearing condition will be abnormal. Therefore, according to the horizontal joint structure of the thatched roof, even if an external force acts due to a difference in temperature and temperature, strong wind, snow, etc., or the repeated action of the external force, the roof plate 20 and the joint fitting 21 are stably attached. Can be maintained, resulting in a longer roof life. Also,
When the external force acting on the insertion cover portion 23 is released, the insertion cover portion 23 returns to the original shape, but at this time, both the leg portions 23c, 2 with respect to the rising portion 22d of the water receiving portion 22.
Since the pressure contact state of 3c is maintained by the urging force,
The plug-in cover portion 23 surely returns to the original mounted state.

In the horizontal joint structure of the thatched roof, the initial assembled state may be such that the curved state of the center portion 23a is secured as shown by the phantom line in FIG. In this case, both legs 23c, 23
The pressure contact state of the c with the rising portion 22d can be reliably maintained, and the pressure contact force of the both leg portions 23c, 23c with respect to the rising portion 22d can be sufficiently secured, so that the deformation resistance of the roof after the construction is increased, and as a result, The strength of the roof is improved. Further, even when the displacement force in the direction away from the joint fitting 21 acts on the roof plate 20, the two leg portions 23c, 23c of the insertion cover portion 23 are expanded by the urging force to extend from the roof plate insertion groove 23b. Roofing board 2
Since the separation of 0 is prevented, the joint fitting 21 is prevented from coming off and the mounting state is abnormal.

In addition, in the horizontal joint structure of the thatched roof, for example, the roof plate insertion groove 23b is inserted into the roof plate 20 on the left side in FIG. 1, and then the roof plate 20 on the right side in FIG.
1 is inserted into the roof plate insertion groove 23b to horizontally connect the roof plates 20 and 20 to each other in the horizontal direction, the space between the roof plate 20 on the left side in FIG. Since the positioning is accurately performed and the insertion state is stable, the next insertion operation of the roof plate 20 can be easily performed, and thus the workability of the installation of the roof plate 20 on the entire roof is improved. At this time, the joint metal fitting 21 is handled in the same manner as the joint metal fitting made of one component, and it is easy to handle at the construction site on the roof, and the workability can be further improved.

Further, for example, in order to correspond to the working width L1 of the roof plate 20 shown in FIG. 3, it is sufficient to adjust only the dimension of the insertion cover portion 23 in the water gradient direction, and the insertion cover portion 23 in the horizontal direction can be adjusted. It is not necessary to change the dimensions, the shape of the water receiving portion 22, or the like. Specifically, for example, after adjusting the dimensions of the metal plate before forming, forming is performed to form the inserting cover 23, so that the inserting cover 23 having a shape corresponding to the working width L1 can be easily obtained. To be In this way, in the horizontal joint structure of the thatched roof, high versatility can be obtained with respect to the working width L1 of the roof plate 20, so that it is possible to use a wide variety of structures as in the conventional techniques shown in FIGS. 7 and 8. It is not necessary to prepare a special joint fitting, and as a result, the cost can be reduced.

Further, since the water receiving portion 22 is formed in a plate shape from a single metal plate, there is no joint or the like in the middle, and high water resistance is obtained. Moreover, since the rising portion 22d formed around the water receiving portion 22 also has no seam, waterproof treatment with a sealing material or the like is unnecessary. As described above, since the horizontal joint structure of the thatched roof is composed of two parts, the insert cover portion 23 can be highly versatile, while the water receiving portion 22 can be highly waterproof. Moreover, both the insertion cover portion 23 and the water receiving portion 22 can be formed by a simple forming operation, so that the forming cost can be reduced.

FIG. 5 is a sectional perspective view showing a second embodiment of the horizontal joint structure for a thatched roof of the present invention. In the horizontal joint structure for a thatched roof of the present embodiment, instead of the insertion cover portion 23 of the horizontal joint structure for the thatched roof of the first embodiment described above, an insertion cover portion indicated by reference numeral 30 in FIG. 5 is adopted. ing. The roof plate 20 and the water receiver 22 are
This is similar to the lateral joint structure of the lateral thatched roof of the embodiment. As shown in FIG. 5, the insertion cover portion 30 is formed by bending a single metal plate, and includes a center portion 30a located at the center and both sides of the center portion 30a in the horizontal direction (in FIG. 5). Roof plate insertion grooves 30b, 30b formed on the left and right)
And a pair of leg portions 3 extending from the vicinity of the roof plate insertion grooves 30b, 30b to both sides of the center portion 30a in the horizontal direction.
0c and 30c. The roof plate insertion groove 30b corresponds to the insertion groove described in claim 1. Both legs 3
0c and 30c are inserted between the rising portions 22d on both sides in the horizontal direction of the water receiving portion 22, and the insertion cover portion 30
Alternatively, the legs 30c are urged by the elasticity of the legs 30c themselves to be pressed against the rising portions 22d.

That is, the insertion cover portion 30 is composed of the two leg portions 3.
Since 0c and 30c are fitted between the rising portions 22d on both sides in the horizontal direction by the urging force in the direction in which they are separated from each other, the attachment state to the water receiving portion 22 is stably ensured. Moreover, since the bending angle of the positioning bending portion 30d formed in the middle of the both leg portions 30c, 30c is about 30 ° at maximum, when the inserting cover portion 30 is subjected to a horizontal displacing force, this displacing force is applied. The leg portion 30c bears most of the load due to the axial force, and the displacement of the insertion cover portion 30 is reliably prevented. Therefore, in the insertion cover portion 23 shown in FIG. 1, a part of the horizontal displacement force is absorbed by the elastic deformation of the positioning curved portion 23e formed on the leg portion 23c, whereas the lateral displacement of the present embodiment. In the lateral joint structure of the thatched roof, the absorbing ability of the displacement force in the leg portion 30c of the insertion cover portion 30 is relatively small, and instead, the leg portion 30
Since the displacement force is counteracted by the axial force of c, the displacement amount of the insertion cover portion 30 with respect to the external force is slightly suppressed, and inconveniences such as disengagement and abnormal mounting state can be more reliably prevented.

Needless to say, the present invention is not limited to the above-described embodiment, and the shapes of the insertion cover and the water receiving portion can be changed as appropriate.
