Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a horizontal roof made of a plurality of long roof plates connected in parallel in the width direction and attached to a base material such as rafters. It is.

(Prior Art) A conventional horizontal roof is disclosed in Japanese Utility Model Application No. 59-117725.

As shown in Fig. 5, this horizontal roof
an upper inner rising portion 3 having an inverted U-shaped cross section rising from one edge in the width direction; a flat portion 4 extending along the main body portion 2 from an edge of the upper inner rising portion 3; 4 and a seal attachment portion 5 rising from the edge of the body portion 2.
an inclined part 6 extending downward from the other end in the width direction; a hanging part 7 hanging down from the edge of the inclined part 6; and a hanging part 7 extending inward from the lower edge of the hanging part 7. A plurality of roof panels 1 having stepped engagement portions 8 are arranged in parallel in the width direction, and each roof panel 1
One end of the base material 1 in the width direction is attached to the base material 1 through a hanger 9 that is fitted into the upper inner rising portion 3 from above.
0, and the engaging part 8 of one roof board 1 adjacent in the width direction is connected to the engaging part 8 surrounded by the main body part 2, the upper inner rising part 3, and the flat part 4 of the other roof board 1. The engaging portion 8 is inserted into the mating recess 11 and
By the plunge engagement into the engagement recess 11, the two adjacent roof panels 1, 1 are connected in the longitudinal direction thereof, and the seal attachment portion 5 of the other roof panel 1 is connected.
The sealing member 12 attached to the one roof plate 1
The connecting portion of both roof panels 1, 1 is sealed in the longitudinal direction by being brought into pressure contact with the inclined portion 6 of the roof panels 1, 1.

This horizontal roof is constructed by fixing one end of the roof plate 1 on the eave side (the one on the left side in FIG. 11 on the other end side of the roof plate 1 on the ridge side (the one on the right side in the figure) is thrust into engagement over the entire length in the longitudinal direction, and then one end of the roof plate 1 on the ridge side It is assembled by repeating the roofing work from the eaves side to the ridge side, in which the roofing section is fixed to the base material 10 using hangers 9.

(Problem to be solved by the invention) However, in such a conventional horizontal roof, the connection between the adjacent roof panels 1, 1 causes the engaging portion 8 to move in the parallel direction of the roof panels 1... This is done by inserting the engagement part 8 into the engagement recess 11 along the longitudinal direction, and in this engagement connection part, the engagement part 8 is pulled out from the engagement recess 11 along the parallel direction of the roof panels 1. There is no means provided to prevent this from happening, and the function of preventing it from coming off is only achieved by fixing the hanger 9 to the base material 10, so it is inevitable that it will be affected by wind, etc. There is a possibility that the engagement and connection portion of the roof panels 1, 1 may become loose.

Furthermore, since the degree to which the engaging portion 8 enters the engaging recess 11 cannot be visually recognized from the outside and cannot be confirmed from the external appearance of the connecting portion of the roof panels 1, 1, the engaging recess of the engaging portion 8 cannot be confirmed from the outside. Coupled with the fact that the engagement with No. 11 is carried out over a long range along the longitudinal direction of the elongated roof board, there is a possibility that such engagement will not be carried out sufficiently and reliably over the entire length in the longitudinal direction. . As described above, if there is a portion where the engagement part 8 is not fully engaged in the engagement recess 11, the engagement part 8 may come off the engagement recess 11 due to the influence of the wind or the like. The rattling will become more noticeable, and
Depending on the poor engagement of the engaging portion 8, the parallelism of the roof panels 1 may not be ensured, which may result in poor external appearance. Even if the parallelism of a pair of roof panels 1, 1 becomes defective, the degree of defect is so slight that the worker will not notice it, but the roof panels 1, 1 that were subsequently installed... In view of the relationship, the degree of parallelism failure becomes so large that it can be clearly recognized visually. When the degree of failure becomes visible, the operator naturally notices that there is a failure in the engagement of the engaging part 8, but in this case, if he tries to correct the parallelism, he will have to do roofing work. You have to start over from the beginning, which is extremely tedious.

Furthermore, if there is a portion of the engagement portion 8 that is poorly engaged, the degree of pressure contact of the seal member 12 to the inclined portion 6 will not be uniform in the longitudinal direction, making it impossible to achieve a good sealing effect and causing the above-mentioned backlash. There is a risk that rainwater may enter.

The object of the present invention is to provide a horizontal roof that solves these problems in conventional roofs.

(Means for Solving the Problems) That is, the horizontal roof of the present invention is a roof plate made by bending a metal plate, and rises from one edge in the width direction of the main body and further extends toward the inside of the main body. an inner fitting concave portion that hangs down from the edge of the upper inner rising portion and further bends inwardly and upwardly of the main body; and from the other widthwise edge of the main body. An outer fitting concave portion that hangs down and further bends toward the inner side and upper side of the main body. It is fixed to the base material through the fitted hangers, and the outer fitting recess of one roof plate adjacent in the width direction is fitted into the inner fitting recess of the other roof plate from the lower side. A sealing member extending along the longitudinal direction of the roof board is inserted between opposing surfaces of the outer fitting recess and the inner fitting recess.

(Example) Hereinafter, the structure of the present invention will be specifically explained based on the example shown in FIGS. 1 to 3.

The horizontal roof of this embodiment has a plurality of roof plates 21...
A plurality of rafters 30, which are base materials, are connected in parallel in the width direction and are perpendicular to the longitudinal direction of the roof board 21.
(only one is shown).

As shown in FIGS. 1 and 2, each roof plate 21 is obtained by bending a long rectangular metal plate, such as a colored steel plate, and has ridges that are vertically inconsistent at both ends in the width direction. A main body part 22 having a shape in which the side flat plate part 22a and the eave side flat plate part 22b are connected by an inclined plate part 22c, a rising plate part 23a rising from one end edge in the width direction of the main body part 22, and the rising plate part 23a. Plate portion 23a
An upper inward rising portion 23 having an L-shaped cross section and a flat plate portion 23b extending inward from the upper edge of the main body in parallel with the ridge side flat plate portion 22a, and the flat plate portion 2
A hanging plate part 24a hanging down from the edge of the hanging plate part 24a, a flat plate part 24b extending inward from the lower edge of the hanging plate part 24a in parallel to the ridge side flat plate part 22a, and the flat plate part 24b. An internal fitting recess 24 having a substantially U-shaped cross section and a rising plate portion 24c rising from an edge in the width direction of the body portion 22, a hanging plate portion 25a hanging from the other edge in the width direction of the main body portion 22, and the hanging plate portion A cross section consisting of a flat plate part 25b extending inward from the lower edge of the eave side flat plate part 22b in parallel with the eave side flat plate part 22b, and a rising plate part 25c rising from the width direction edge of the flat plate part 25b. A substantially U-shaped outer fitting concave portion 25 and the rising plate portion 2
A draining portion 26 extends from the upper end edge of the main body inward and downward in an inclined manner.

A band-shaped sealing member 27 made of an elastic material is attached to the rising plate portion 24c of the inner fitting recessed portion 24 of each roof plate 21 and extending along the longitudinal direction thereof.

One end side portion in the width direction of each roof plate 21, that is, the ridge side portion has a plurality of hangers 29 fitted into the upper inner rising portion 23 and inner fitting recessed portion 24 from above.
... (only one is shown) is fixed to each rafter 30. Each hanger 29, as shown in FIG.
A substantially U-shaped support piece 29a attached to cover the hanging plate part 24a of the upper inward rising part 23 and the inner fitting recessed part 24, and a support piece 29a extending from one end of the support piece 29a to the rafter 30. It is made of metal and consists of a mounting piece 29b that is attached by a stop such as a self-drilling screw, and the other end of the support piece 29a is the upper surface of the flat support plate 24b of the inner fitting recess 24. is in contact with.

The other end side portion in the width direction of each roof plate 21, that is, the eave side portion, has its outer fitting concave portion 25 facing the eave side (as shown in Fig. 1).
It is connected to one end in the width direction of the roof sheet 21 on the eave side by fitting from the lower side into the inner fitting recess 24 of the adjacent roof sheet 21 (lower left direction side). In this connected state, the eave side flat plate part 22b of the main body part 22 is superimposed on the flat plate part 23b of the upper inner rising part 23, and the rising plate part 25c of the outer fitting recessed part 25 and the flat plate part 23b of the upper inner rising part 23 are overlapped. The carrier plate portions 25b are the hanging plate portions 24a of the inner fitting recessed portions 24, respectively.
The sealing member 27 that is in contact with the flat plate portion 24b and affixed to the rising plate portion 24c of the inner fitting recessed portion 24 connects the rising plate portion 24c and the outer fitting recessed portion 25 facing thereto. It is also clamped with the hanging plate portion 25a. In this condition, one roof board 2
The outer fitting recess 25 of one roof plate 21 is fitted into the inner fitting recess 24 of the other roof plate 21 from below, so that the inner fitting recess 24 is attached to the rafters 30 by the hangers 29. Coupled with the fact that the roof panels 21, 21 are fixedly held, the roof panels 21, 21 are firmly connected without wobbling in the parallel direction of the roof panels 21, and the connected portion of the roof panels 21, 21 is connected in the longitudinal direction. The entire length is well sealed by the sealing member 27, and rainwater is prevented from entering into the back side of the roof board inside.

Therefore, in a horizontal roof with such a configuration, the ridge side part of the eave side roof board 21 (the one on the left in FIG. 3) is
It is fixed to the rafters 30 through the hangers 29 that are fitted into the upper inward rising portion 23 and the inner fitting recessed portion 24 from above, and the roof on the ridge side is attached to the inner fitting recessed portion 24. Fit the outer fitting concave portion 25 of the eave side portion of the plate 21 (the one on the right side in the figure) from the lower side,
Further, the ridge-side flat plate portion 22a of the main body portion 22, which is the ridge-side portion of the ridge-side roof plate 21, and the upper inward rising portion 2
3 and the inner fitting concave portion 24 are fixed to the rafters 30 through the hangers 29, and the roofing work is repeated from the eaves side to the ridge side. By the way, the fitting of the outer fitting recessed part 25 into the inner fitting recessed part 24 is performed by the roof plate 21 on the ridge side.
While tilting with respect to the roof board 21 on the eave side, pull it towards the ridge side, and first, guide the inner fitting recessed part 24 relatively between the eave side flat support plate part 22b of the main body part 22 and the draining part 26. (FIG. 3A), while the inner fitting recess 24 is guided by the water cutter 26, the lower end portion thereof is placed within the outer fitting recess 25, that is, between the hanging plate part 25a and the rising plate part 25c. (Fig. 3B), the ridge side flat part 22 of the ridge side roof board 21
a and the eave side flat plate part 22b are respectively received by the rafters 30... and the ridge side flat plate part 22a of the eave side roof board 21 (and the hanger 29... which holds it). This can be done easily and reliably by rotating the roof plate 21 on the ridge side downward (FIG. 3C). In this case, as long as the lower end portion of the inner fitting recess 24 protrudes even slightly into the outer fitting recess 25, the outer fitting recess 25 will then move into the inner fitting recess as the roof plate 21 rotates. 24 over its entire length in the longitudinal direction, and there is no possibility of incomplete fitting of the outer fitting recess 25 to the inner fitting recess 24 in the longitudinal direction. Further, due to the presence of the draining portion 26, it performs a guiding action during fitting, and the insertion of the inner fitting recessed portion 24 into the outer fitting recessed portion 25 is performed better than in the case where the draining portion 26 is not provided. You will be killed.

Note that the structure of the horizontal roof is not limited to the above embodiment, and for example, as shown in FIG. The ridge side roof board 21 is changed from the state shown in FIG. 3A to the state shown in FIG. The inner fitting recess 2 of the outer fitting recess 25 is minimized to minimize interference with the eave side roof board 21 when changing the
It is possible to adopt a shape devised so that the fitting operation to 4 can be performed more easily. Furthermore, the cross-sectional shape of the upper inward rising portion 23 is shaped like a step or approximately C-shaped as shown in FIG.
They can also be formed in a letter shape. Further, the sealing member 27 may be inserted between the facing surfaces of the inner fitting recessed portion 24 and the outer fitting recessed portion 25, and may be attached to the hanging plate portion 25a side and attached to the rising plate portion 25.
c and the hanging plate portion 25a, the flat plate portions 24b, 2
5b and between the hanging plate part 24a and the rising plate part 25c, or all of them can be inserted therein. Further, although it is not necessary to provide the draining plate 26, if it is provided in an inclined shape and long as in the above embodiment, the ridge side flat plate portion 22a of the main body portion 22
Rainwater entering the upper inward rising portion 23 from between the flat plate portion 25b of the outer fitting recess 25 and the hanging plate portion 24a of the inner fitting recess 24 and the outer fitting recess 2
5 can be effectively prevented from entering from between the upper inner rising portion 25c of the outer fitting recessed portion 25.
It has the advantage that it also functions as a guide plate that makes it easier and more reliable to fit into the inner fitting recess 24.

(Effect of the invention) The horizontal roof of the invention connects adjacent roof sheets by fitting the outer fitting recess into the inner fitting recess from the lower side. The wobbling of the plates in the parallel direction is effectively prevented,
The connection between the roof panels is strong and will not be adversely affected by wind, etc.

Furthermore, in connection work between roof panels, as long as the lower end of the inner fitting recess protrudes even slightly into the outer fitting recess, the outer fitting recess can be properly fitted into the inner fitting recess. will be held. If there is a place where such plunge fitting is not performed at all, the appearance of the roof shingles will change markedly in the vertical direction at this place, and such an abnormality in the appearance will be clearly confirmed by the operator. This makes it possible to carry out correction work immediately. Therefore, according to the present invention, even though the roof panels are long, the connection between the roof panels by fitting the outer fitting recess into the inner fitting recess can be achieved by redoing the roofing work. This can be done properly and reliably over all parts in the longitudinal direction without causing such troubles, and it is possible to provide a horizontally-roofed roof with good appearance and good appearance.

Moreover, since the outer fitting recess is properly fitted into the inner fitting recess in this way, the sealing action by the sealing member inserted between the opposing surfaces of both parts extends over the entire longitudinal direction. In addition to the fact that the process is performed uniformly and well, and as mentioned above, there is no wobbling,
There is no risk of rainwater entering through the joints between the roof panels.
