And various inventions are disclosed in JP-A-8-199723. In addition, the present applicant has also filed Japanese Patent Application No. 8-1834.
No. 70 and some other inventions described in the drawings are proposed.

[0003] The use of metal tiles for roofs of detached houses and condominiums in this way, and the use of roof panels or building wrappings, which have been completed as roofing materials, produced as functionally integrated unit members at factories. However, technological development of a unit type roof constructed as a hanging work from the ground side by a crane or the like or a construction method for constructing the same roof has been partially completed for a long time. It has been done.

[0004]

[Problems to be solved by the present invention] However, in the above-mentioned proposals for technical development, it is necessary to construct a part of a roof that has been left uncovered at a construction site on a roof surface after installing a panel, or a roofing material that is easily damaged. It was said that the project had no mention of the method of suspension at the site.
In other words, it is only at the stage of bundling of individual partial technologies, and the fact is that there is no general technology that can be said to have been completed and practically completed by constructing the roof.

It can be said that the Japanese housing industry is one of the most remarkable industrialized countries in the world. One of the goals is to produce the components in the factory as much as possible, and to reduce or reduce the work on the construction site as much as possible. In general, it is not technically easy to unitize up to the stage including the final finishing material. The reason lies in the difficulty of connecting parts between panels and connecting parts with members of other parts. In other words, the final finishing material must satisfy the aesthetic appearance and the protection against the external environment, that is, the heat, water, sound insulation and durability, which is a problem to be solved in the above-mentioned parts. Is difficult. In order to convert on-site work to in-plant work and achieve total economic effects, unitization of each part must be developed in a well-balanced manner.

[0006] As for the roof, there is no example of unitizing it to the stage where no roofing material is required at the construction site. Also, there is no total idea including the on-site construction method. For this reason, the actual situation is that the shortening of the construction period for roofs and the progress of industrialization have not been realized. In particular, in Japan, the benefits of being able to construct a roof that can rain in a short period of time with a lot of rain are enormous for both the construction side and the orderer side. Therefore, the desire to achieve this is very high.

In order to complete a roof in a short period of time, especially in one day, all of the following problems must be solved at the same time, which is why this has not been realized today. 1. At the construction site, all necessary parts such as roofing materials and water drainage must be installed on a single panel.

[0008] 2. The rain at the joints between panels is perfect, stable and durable. 3. There is no need for special skills or craftsmanship for the construction for that,
General workers should be able to perform the work. 4. The ridge members for storing the top of the roof panel are also complete with all ridge wrapping and necessary related parts, and can be constructed without special skills or craftsmanship at the time of site installation.

[0009] 5. The rain should be complete, reliable and durable. 6. Roof panels satisfying the above conditions and building methods for building members at the construction site have been established as appropriate methods. That is, a hanging metal fitting and a device related thereto that enable safe, reliable, and economical construction work in a short time without damaging a panel member and a ridge member having a rain finishing mechanism, which can be attached to a finishing material. Is prepared.

The problem to be solved by the present invention is to solve the above problems 1 to 6 which have not been solved as a whole as a system.

[0022]

BEST MODE FOR CARRYING OUT THE INVENTION A unit-type metal tile roof according to the first aspect of the present invention, as shown in FIG. A plurality of unitized roof panels 3 are suspended on the main building 2 of the building, and the unitized building wrapper 4 is suspended in the building.

The roof panel 3 is, as exemplified in FIG.
A rafter 5 as a necessary related part, a base plate 6, and a waterproof sheet such as asphalt roofing as a waterproof material is installed on the upper surface of the base plate 6, and further, a metal roof 7 is integrally combined to provide a functional composite. Unit.
The roof panel 3 shown in FIG. 1 has a length (for example, 4.8 m) that extends continuously from the roof ridge to the eaves in the flow direction (for example, 4.8 m). (For example, 1.8 m). When the metal roof tile 7 is cut in the width direction, the standard cross-sectional shape is manufactured as shown in FIG. 3, and the roof flow direction is basically the same as the roof panel and is continuous from the roof ridge to the eave tip in the flow direction. Made to length. This metal tile 7 is a roof panel 3
Are laid one after the other in the width direction. In addition,
The length of the roof panel 3 is divided into a plurality of parts from the roof ridge to the eaves in the flow direction.
It is also possible to successively add and construct by the method disclosed in the specification and the drawings of 183470.

In the roof panel 3, the overlap splicing end A on the right side in FIG. 2 where the roof panel to be post-processed overlaps has a length extending over the entire length in the flow direction of the roof at an inner portion along the outer edge of the panel. Is installed on the base plate 6 by gluing, etc.
The outer edge 7a of the metal roof tile 7 is located slightly inside the outer wall 8a of the dump gutter 8. On the other hand, at the lap splicing end B on the opposite side (left side in FIG. 2) that is superimposed on the roof panel of the previous construction, the flow direction of the roof is located between the metal tile 7 and the base plate 6 along the end. A draining roof pier 9 having a length corresponding to the entire length of the roof is fixed to the base plate 6 with screws 10. The draining roof pier 9 is, for example, a molded product made of steel. The metal tile 7 is fixed to the draining roof pier 9 with a self-tapping screw 11 having a vertical downward facing top portion of a mountain portion straddling the draining roof pier 9. In addition,
Instead of the self-tapping screw 11, the metal tile 7 can be fixed with a wood screw directly screwed into the base plate 6 through a through hole formed in the drainage roof pier 9. Outer edge 7 of the metal roof tile 7
b is the required lap joint size (about 75) from the outer edge of the roof panel 3 over the entire length in the flow direction of the roof.
mm).

The roof pier 12 in FIG. 2 is also a steel molded product, for example, a pier having a short length in the direction of the roof flow on the upper surface of the base plate 6, and a row of ridges in a specific mountain having a metal roof tile 7. It is fixed with wood screws 13 at two places, the side and the eaves side. The length may be the entire length in the flow direction. The role of the roof pier 12 is like a ruler that determines the mounting position of the metal tile 7 in the manufacturing process of the roof panel 3 by using the mountain portion of the metal tile 7. Thus, the metal roof tiles 7 to be installed on one roof panel 3 in a plurality of ratios are fixed to the drained roof pier 9 as described above, and detailed illustration is omitted. A hole for a screw is made, and the hole is fastened to the base plate 6 with a wood screw through this hole, and a sufficient water stop and a waterproof material are applied to secure the hole.

The drainage roof pier 9 is provided on the premise that the roof panel 3 is to be constructed by lap splicing as shown in FIGS. 4 and 5, beyond the outer wall 8a of the dumping gutter 8 of the preceding panel on the left side in the figure. Outer edge 7a of metal roof tile 7 of the preceding panel (adjacent)
The water return portion 9a, which has a downward slope and extends to a position where a slight gap (about 10 mm so as not to hinder the drainage of infiltration water) is left, causes interference with the outer wall 8a of the dump gutter 8. Not in height position.

Accordingly, the roof panel 3 shown in FIG. 2 has a construction in which the hanging operation proceeds in the order from the left to the right of the roof as shown in FIGS. 4 and 5, the roof panel 3A on the left side in the figure, which is suspended and installed on the main house 2 of the hut group in advance, is adjacent to the roof panel 3B on the right side in the figure, which is suspended from the rear at the center K position. The rafters 5, 5 are vertically lowered so that a gap of about 2 mm is left. Then, the ends of the adjacent metal roof tiles 7 and 7 are exactly overlapped with a predetermined overlap size, and the front return sloped water return portion 9a of the drainage roof pier 9 extending to the left in the drawing is provided with the drainage gutter 8 Outer wall 8
a without leaving any interference with the outer edge 7a of the adjacent metal roof tile 7 beyond the outer wall 8a of the gutter 8. Therefore, even if the rainwater that has permeated the overlapping portions of the metal tiles 7 and 7 gushes to the right from the outer edge 7a due to heavy rain or strong wind, the fountain must be inclined downward in front of the drainage roof pier 9. The water hits the water return portion 9a and falls toward the front side, and is stored in the drain gutter 8. Therefore, the rainwater never leaks between the two adjacent rafters 5, 5, and there is no problem of the rain breakage (water stoppage, waterproofing) at the overlapping portion. In addition, regarding the roof panel which forms a gable at the left end of the roof and a gable at the right end, the drainage roof pier 9
And the outer edge 7 of the metal roof tile 7
The b and 7a are arranged so as to be aligned with the outer edge of the panel, and are pressed down and fixed to the base plate 6 with a wood screw to ensure good rain and good aesthetics.

The roof panel 3 is roughly divided into two types of structures for the rain closing (water stoppage, waterproof) treatment at the upper end on the ridge side (FIGS. 6 and 7). However, there is no essential difference between the two structures, and a waterproof plate 14 having a shape and arrangement surrounding the outside of the upper end of the metal roof tile 7 from the bottom surface to the end surface and the upper surface is fixed to the field plate 6 with screws 15. In addition, a configuration in which a drainage plate on the ridge wrapping side, which will be described later, is mounted on the upper part of the water stop plate 14 and has a superposed portion 14a which is in close contact is basically common. The water stop plate 14 in FIG. 6 has the overlapping portion 14a oriented substantially parallel to the base plate 6,
The water stop plate 14 of FIG. 7 is different in the configuration in which the overlapping portion 14a is provided in a state of being bent inward. The difference is that
Since it is exhibited in relation to ridge parcel 4, its significance will be described later.

Reference numeral 19 in FIGS. 6 and 7 denotes the roof panel 3.
Of the water stop plate 14 (see FIG. 5) cut off at the spliced portion so as not to interfere with each other because it is necessary to hang it on the upper surface of the hut set 1 and install it in a spliced manner. (Water stoppage, waterproof)
An angle-shaped joint fitting which is inserted into the back side of the water-stop plate 14 so as to be wrapped in a necessary length in the longitudinal direction from the back side of the hut assembly 1 at the joint of the missing portions of 14 and installed. A considerable gap 25 is provided between the bottom surface of the water stop plate 14 and the base plate 6 to facilitate the insertion of the joint fitting 19.

Next, the wrapper 4 is also roughly classified into two types according to the two types of structures of the waterproof plate 14 (FIG. 8, FIG. 8).
(FIG. 10). However, the ridge packet 4 has a plurality of bracket-shaped fixing brackets 16 projecting vertically downward at the center of the lower surface thereof at intervals in the longitudinal direction, and substantially on both sides in the inclined direction over the entire length of the lower surface in the ridge direction. The ventilation member 17 is provided in a symmetrical arrangement, and a draining plate 18 is provided integrally on the lower surface of the ventilation member 17 so as to overlap and adhere to the overlapping portion 14a of the waterproof plate 14 of the roof panel 3. The unit configuration is basically the same. A bolt 42 and a receiving hardware 40 are attached to a lower portion of the fixing bracket 16 with a nut 43 in advance. The ventilation member 17 is a structural material in which a large number of ventilation holes penetrating in the flow direction of the roof are formed in a honeycomb shape. The difference between the embodiment of FIG. 8 and FIG. 10 relating to the ridge package 4 is the difference in the form housed in the ridge portion as shown in FIG. 9 and FIG. 11, and therefore will be described based on FIG. 9 and FIG.

In the embodiment shown in FIG. 8 and FIG. 9, the drain plate 18 on the side of the wrapper 4 corresponds to the fact that the waterproof plate 14 of the roof panel 3 has the overlapping portion 14a substantially parallel to the flow direction of the roof. It is formed in the shape of a flat plate which is superimposed on the overlapping portion 14a so as to be in close contact therewith, and the positioning and fixing can be easily and stably performed by the overlapping portions 14a, 14a on both the right and left sides, which are, in other words, good mountain-shaped sitting. ing. Drainer 18
Has a water-stop wall 18a at the back end for stopping rainwater that flows through the ventilation member 17 in case there is rainwater. However, the mountain-shaped ridge envelope 4 itself is also provided at a position slightly outside the outer edge of the ventilation member 17 with a waterproof step portion 4a for shielding rainwater in a strong wind from directly blowing into the ventilation member 17. Is provided, there is no need to worry about rainwater blowing into the ventilation member 17 even during a typhoon.

In the embodiment shown in FIGS. 10 and 11, the mountain-shaped ridge 4 is bent in two stages, and a ventilation member 17 is provided on the lower surface of the lower side. The draining plate 18 is largely bent upward at the inner end position of the ventilation member 17, and the bent portion 18 b overlaps with the overlapping portion 14 a of the water blocking plate 14 so as to be in close contact with the overlapping portion.
According to a, the positioning and fixing can be easily and stably performed by the good sitting shape of the mountain shape (FIG. 11). The bent portion 18b of the draining plate 18 and the water blocking wall 18a are the ventilation member 1
It works to stop rainwater flowing through 7 as much as possible. The ridge packet 4 also includes a waterproof stepped portion 4a at a position slightly outside the outer edge of the ventilation member 17 for shielding rainwater in a strong wind from blowing into the ventilation member 17 as much as possible.

Thus, the metal tile roof realizes necessary and sufficient ventilation of the roof (ridge ventilation) due to the presence of the ventilation member 17 of the ridge packet 4. The rainwater that is going to enter the building during a strong wind or heavy rain is first supplied to the waterproof step portion 4 a of the building package 4.
The rainwater that has entered through the ventilation member 17 is blocked by the water blocking wall 18 a of the drain plate 18. In addition, since rainwater that tends to enter along the roof panel surface is blocked by the overlapping portion 14a of the water stop plate 14, the draining plate 18 and the water stop plate 14, a rain operation that completely prevents water leakage into the building is performed. Configure.

However, the combination of the components of the roof panel 3 and the components of the ridge wrapping is not limited to the above embodiment. In some cases, the ridge parcel 4 has only the fixing brackets 16 and all other components are unitized on the side of the roof panel 3 or the ridge parcel 4 includes the ventilation member 17, and the draining board 18 is provided on the roof. Various combinations such as a constituent material of the panel 3 can be used.

In addition, as another embodiment in which the upper end of the ridge side is different from the rain stop, as shown in FIG.
The ridge door 51 replacing the 4 is attached to the upper surface near the upper end of the roof panel. As shown in FIGS. 19A and 19B, the ridge-side door 51 has a portion in contact with the upper surface of the metal roof 7 in a wavy shape corresponding to the waveform of the metal roof 7, and a water-impervious surface 51 b rising vertically from the wavy portion. An overlapping portion 51a that is bent horizontally from the portion 51b is provided, and the draining plate 18 of the ventilation member 17 of the ridge wrapper 4 closely overlaps the overlapping portion 51a. The ridge door 51 of FIGS. 18 and 19A is made of a steel plate, and the ridge door 51 of FIG. 19A is made of a closed-cell foam synthetic resin or the like. The ridge door 51
Is used, a U-shaped joint fitting 52 is used at the upper end of the metal roof tile 7 instead of the angle-shaped joint fitting 19 described above.

On the premise of the above configuration, a method of constructing a unit type metal tile roof according to the invention described in claim 7 will be described. A plurality of roof panels 3 unitized in the above-described configuration are sequentially suspended on the upper surface of the hut group 1 in a predetermined order on the upper surface of the hut group 1 previously constructed, and then the unit package 4 unitized to the ridge is formed. It is carried out in the process of hanging and constructing.

The roof panel 3 is preferably suspended at three to four locations of the panel, ie, at one or two locations on the eaves side and at one or two locations on the ridge side, using soft metal roof tiles 7 or a field board 6 or the like. Using a detachable roof panel suspension mechanism that has a structure that does not damage the roof and is lifted from a ground site with a crane or the like (see FIG. 12). A roof panel 3 in which a plurality of rafters 5 are arranged in parallel as a roof panel suspension mechanism (see FIG. 1)
