Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a construction method for a tiled roof using tiled timbers and an assembled timber panel used therefor.

[Prior Art] Conventionally, as a tile roof construction method that does not use roofing soil, for example, as shown in Fig. 8, a waterproof sheet is used as a roof base on a roof surface (Ao) made of field boards (4'). A waterproof layer (5°) is laid, and on top of that, horizontal tile beams (1
2') are arranged and fixed at intervals corresponding to the climbing leg dimension (0) of the tile (K), and the curved edge (K1) on the back of the rear end of the tile (K) is engaged with this tile crosspiece (12'). The so-called hanging sill construction method, in which roof tiles (K) are placed side by side in sequence, is widely known.

In addition, as a durable construction method for tiled crosspieces, the applicant has proposed a vertical crosspiece (I
F) are arranged according to the dimensions of the tile (K) in the horizontal direction, and the engaging part (K2) on the curved edge (K1) of the rear end of the tile is attached to the longitudinal crosspiece ( 11') and proposed a construction method in which they are installed in parallel in the vertical direction (Japanese Patent Laid-Open No. 19435/1986).
Publication No. 2).

[Problems to be Solved by the Invention] However, in these hooking beam construction methods, the horizontal beams are allocated and marked according to the climbing foot dimensions of the tiles, and a large number of horizontal beams are arranged and fixed by nailing (the beam is fixed). ), and the work is extremely time-consuming. In particular, in the case of a construction method that uses vertical beams, the vertical beams also require the same sorting, marking, and cross-cutting as the horizontal beams, which increases the amount of work required for the construction work and lengthens the construction period. The work also requires considerable skill.

In addition, before the above-mentioned work of laying the bridges, the troublesome work of laying a waterproof layer as a roof base on the roof surface is additionally required.

In particular, the construction of this waterproof layer involves spreading waterproof sheet materials such as kraft paper impregnated with asphalt, sheets of paper coated with rubber or synthetic resin, and partially overlapping them. The sheet material is laid in the same way and fixed at the overlapped portions using staples or nailing, but since this sheet material is thin and wide and long, it is difficult to handle and is easily blown up or rolled up by the wind. Therefore, the installation work is difficult, especially when working on a roof with a large slope or during strong winds, making it extremely difficult and dangerous work, leading to an increase in the number of work hours.

In view of the above, the present invention aims to simplify the work of arranging a large number of crosspieces in parallel when constructing a tiled roof using tiled crosspieces. The assembly crosspieces arranged in a grid pattern and formed into a predetermined planar shape are arranged and fixed in parallel on the roof surface. In particular, in this invention, a waterproof sheet material is stretched on the lower surface of the assembly crosspieces. This invention was invented for the purpose of simultaneously and easily constructing a waterproof layer by constructing a crosspiece.

[Means for Solving the Problems] The first aspect of the present invention is a method of constructing a tiled roof to solve the above three problems, in which a plurality of vertical and horizontal beams are installed at predetermined intervals with one side facing upward. are arranged in a lattice pattern and joined at their intersections to form a predetermined planar shape determined according to the roof surface.A waterproof material is applied to the lower surface of the assembly crosspiece over the entire surface. Using the required number of prefabricated crosspiece panels made by stretching sheet materials, the prefabricated crosspiece panels are sequentially arranged side by side on the roof surface where the field surface is formed, and at the joints between adjacent panels, one panel The extended end of the sheet material of the first panel and the sheet material of the other panel are arranged and fixed side by side so as to overlap each other, and roofing tiles are sequentially placed side by side on the assembled crosspiece panel to perform tile roofing.

The second aspect of the present invention relates to an assembled crosspiece panel used for constructing the above-mentioned tiled roof, in which a plurality of vertical and horizontal crosspieces are arranged in a lattice shape at predetermined intervals with one side facing upward. An assembled crosspiece is formed by joining together at the intersection,
A waterproof sheet material is stretched over the entire surface of the lower surface of the assembled frame. In particular, the sheet material is characterized in that the sheet material is at least one of the upper and lower sides and/or at least one of the left and right sides. It is preferable that the end portion of the sheet extends from the assembly crosspiece so that it can be overlapped with the sheet material of an adjacent panel.

[Function] According to the present invention described above, when constructing a tiled roof, on a roof surface on which a field surface is formed, assembled crosspiece panels having a predetermined planar shape determined according to the roof surface are sequentially assembled. These are installed and fixed side by side, so that the vertical crosspieces and the horizontal crosspieces can be easily installed side by side at predetermined intervals over the entire roof surface.

In particular, the assembled crosspiece panels used in the present invention have a waterproof sheet material stretched over the entire lower surface, so when they are installed and fixed side by side as described above, the joints between adjacent assembled crosspiece panels By arranging and fixing the extending end of the sheet material of one panel and the sheet material of the other panel in a superimposed manner, a waterproof layer as a roof base can be simultaneously constructed without the same problem.

That is, by using the assembled crosspiece panel of the present invention in which the end of the sheet material on at least one of the upper and lower sides of the panel and/or at least one of the left and right sides extends from the assembled crosspiece, for example, the panels adjacent to the left and right can be At the joints between panels, the sheet material from the other panel is placed on the extended end of the sheet material from one panel, and at the joints between panels that are vertically adjacent in the slope direction, the sheet from the lower panel The assembly crosspieces may be placed side by side butt against each other so that the end of the sheet material of the upper panel is placed on the upper side extending end of the material, thereby creating a waterproof layer of waterproof sheet material. This means that the construction can be carried out without the risk of rainwater entering.

Moreover, according to the assembled panel panel of the present invention, the assembly panel consisting of both vertical and horizontal panels serves as a shape preservation and holding frame for the thin and wide waterproof sheet material stretched thereon, and can be easily assembled into a regular-shaped panel. The waterproof sheet material can be easily handled, and there is no risk of the waterproof sheet material being blown up or rolled up by the wind during the installation work, making the construction work easy.

Therefore, a tiled roof can be constructed by simply arranging and fixing the assembled crosspiece panels in parallel as described above, and placing the tiles on top of the panels while sequentially securing them to the crosspieces in the same manner as in the conventional hanging crosspiece construction method.

[Example] Next, embodiments of the present invention will be described below based on the drawings.

In the figure, (1) is a rafter that is placed over the main building (2), eaves girder (3), and ridgepole, and (4) is a roof board that is stretched over the rafter ((). These constitute the long surface (A).

The assembled crosspiece panel <10> used in the present invention has the following configuration as illustrated in FIGS. 1 to 4 and FIG. 5 (FIG. 6).

Each has multiple vertical crosspieces (11) and horizontal crosspieces (12),
They are arranged in a vertical and horizontal grid pattern at predetermined intervals set according to the tile dimensions, etc., and nailing means (
13), etc., to form an assembly crosspiece (20) having a predetermined planar shape and size determined according to the roof surface (A).

In the case of the assembly crosspiece (20) of the embodiment shown in FIGS. 1 to 4, the horizontal crosspiece (I2) has tiles (K) arranged side by side in order, and has a curved edge (K1>) between the rear ends. The interval (11) corresponding to the climbing leg dimension ( ) □) of the tile (K) so that it can be locked.
The vertical crosspieces (11) are arranged in parallel with the horizontal crosspieces (12).
), the tiles (K) are successively attached to the curved edges (K1).
The horizontal layout of the tiles (K) is arranged at intervals (4z) corresponding to the dimensions so that the tiles (K) can be placed side by side so as to lock the engagement recesses (K2) in a part of the tiles.

A sheet material (15) of a waterproof material constituting a waterproof layer (5) for the roof base is stretched over the entire surface of the lower surface of the assembly crosspiece panel (10).
). In particular, the sheet material (t5) of the assembled crosspiece panel (10) is such that, as shown in the figure, one of the upper and lower sides of the panel, for example, the upper side, and the sheet end on one of the left and right sides of the panel (10) sheet material (15
) is formed to extend a required length (approximately 10 to 20 cm) from the assembly crosspiece (20) so that it can be overlapped with the assembly crosspiece (20). (
15a) indicates an extending end on the upper side, and (15b) indicates an extending end on the left and right sides.

In addition, assembled timber panels (10) used for regular roof surfaces
Usually, the ends of the sheet material (i5) are extended at one of the upper and lower sides and one of the left and right sides as described above, but for example, panels that are installed side by side only on the left and right sides, such as for eaves roofs, etc. In this case, one of the sheet ends on the left and right sides should be extended, and in the case of panels that are arranged side by side only vertically, it is sufficient to just have one sheet end on the top and bottom sides extended. In addition, it is also possible to extend the sheet end portions at each side around the panel as described above and cut off the unnecessary extended end portions during installation.

This sheet material (15) may be, for example, waterproof paper made by impregnating paper with asphalt, waterproof sheet material made by coating or laminating paper or cloth with rubber or synthetic resin, or synthetic resin film or sheet, or foamed material such as foamed polyethylene. A waterproof sheet material is used that can be used as a sheet, or as a base material for a roof such as these sheets.

This sheet material (15) has vertical and horizontal crosspieces (11) (12)
The assembled crosspiece (2) is attached to the lower surface of the lower crosspiece by adhesive means, etc., and the horizontal crosspiece (12) is arranged on the lower side.
0), the surface has uneven stripes (25a) as shown in the figure.
) (25b) using a corrugated sheet of synthetic resin,
The uneven stripes (25a) and (25b) are bonded in the direction of the roof slope using the raised stripes (25b) to create a gap between the horizontal crosspiece (12) and the sheet material (15) due to the grooved stripes (25a). This is suitable because it can ensure drainage in the slope direction.

Among them, if a corrugated synthetic resin foam sheet is used, it will also have a heat insulating effect.

Of course, by forming a groove on the bottom side of the horizontal crosspiece (12), etc.
It is also possible to provide drainage properties by other means.

In addition, as shown in the figure, the assembly crosspieces (2o) of the assembled crosspiece panel (10), which is generally rectangular in plan, used for a normal roof surface (A), have vertical crosspieces (II) arranged on one of the left and right sides. , and each vertical crosspiece (11) at each interval ()L) using this as a reference.
On the other side opposite to this, the end (12a) of the horizontal crosspiece (12) is connected to the vertical crosspiece (11) (11).
A length corresponding to the interval ()+) of l1jl is left in a protruding shape, and a horizontal crosspiece ((2) is placed on one of the upper and lower sides, for example, on the lower side as shown in the figure, and using this as a reference, the above-mentioned The horizontal crosspieces (12) are arranged at intervals (j!t), and on the upper side opposite to this, the ends (lla) of the vertical crosspieces (tl) are arranged at intervals between the horizontal crosspieces (12) (12). ()3)
It is preferable to leave it in a protruding shape for a length corresponding to .

By forming the vertical and horizontal crosspieces (II) (12) as described above, when installing the assembled crosspiece panels (1o) in parallel on the roof surface (^), the ends of the horizontal crosspieces (12) ( X
Za) or the end (lla) of the vertical crosspiece (11) is butted against the vertical crosspiece (11) or horizontal crosspiece (12) on the side of the adjacent assembled crosspiece panel (10), respectively. The extending ends of the sheet material (15) are arranged so that the crosspieces (11) and (12) can be arranged in a straight line at regular intervals, and are stretched on the lower surface at the joints between the panels that are adjacent to each other on the left and right and on the top and bottom in the slope direction. Part (15a) (15b
) and the adjacent panel (7) (see) H (15) overlap, and this overlapping portion is suppressed by the crosspiece.

For normal roof surfaces, the assembled crosspiece panels (10) having the above configuration are mainly used, but if tile seats are not attached to the eaves and both left and right bolts of the roof surface, the above structure is used as a whole. The same basic configuration is possible, especially in the case where a tile seat with a roughly triangular cross section is placed on the lower side corresponding to the tip of the eaves instead of the horizontal crosspiece, or a vertical tile seat with a roughly triangular cross section on one of the left and right sides is placed on the vertical crosspiece. Instead, a panel is used (not shown), which is arranged to form an assembly crosspiece, on which a waterproof sheet material (15) is stretched in the same manner as described above, and has a grooved bottom.

Although not shown, both vertical and horizontal crosspieces are installed near the bright line where the roof surfaces of a hipped roof intersect, or near the valley where the roof surfaces of a T-shaped roof intersect. In addition to being arranged in the same manner as above, the assembly crosspieces are roughly triangular in plan and have hypotenuses corresponding to corner ridges or valleys, and a waterproof sheet material is stretched on the lower surface of the assembly crosspieces in the same manner as above. Use wooden panels. In the case of this embodiment as well, the edge of the sheet is extended to a required length at the side where it joins an adjacent panel, if necessary.

In addition, in the above-mentioned example, the vertical crosspiece (11) is a roof tile (
Although the assembled crosspiece panels (lO) are arranged on the horizontal crosspieces (12) so as to lock the horizontal crosspieces (12), the present invention is applicable to the general horizontal crosspiece construction method, the so-called hook construction method.
Even in the case where a vertical crosspiece is disposed under a horizontal crosspiece to provide a gap for water drainage, the same method as described above can be carried out as shown in FIGS. 5 and 6.

This assembled crosspiece panel (10) is placed on the lower side of the horizontal crosspieces <12> arranged at intervals ()1) corresponding to the climbing leg dimensions.
For example, a plurality of comparatively thin vertical crosspieces (31) for maintaining a gap with the roof surface (A) are arranged at about the same intervals as the rafters (1), and the horizontal crosspieces (12) and the vertical crosspieces (12) The crosspieces (2()) are connected and integrated by nailing means (13) at their intersections to form an assembled crosspiece (20).The thickness of the vertical crosspiece (21) in this case is about 5 to 15 mm. Then, a waterproof sheet material (15) is glued and stretched over the entire surface of the lower surface of this assembly crosspiece (20) to the lower crosspiece (21), and the joint edge with the adjacent panel is The sheet end on one of the upper and lower sides of the panel and/or one of the left and right sides is extended a required length in the same manner as described above.

Each of the above-mentioned crosspiece assemblies (lO) is manufactured in a factory, etc., and at that time, by using appropriate formwork and equipment, the dimensions are determined, arranged, joined, and waterproof sheets + 4'
(15) The tensioning etc. can be performed mechanically and easily. The size is set appropriately depending on the tile dimensions and the roof surface, but the vertical and horizontal dimensions for square tiles are usually about 1.0 to 3.0 m, and the vertical and horizontal dimensions for triangular tiles are usually about 1.0 to 3.0 m. Each is set within a range of about 1.0 to 2.0 m. Also, vertical crosspiece (11) and horizontal crosspiece (12)
is usually made of wood with a thickness of about 10 to 25 mm.

In addition, other crosspiece materials such as synthetic resin materials and metal materials can be used. In the case of synthetic resin materials and metal materials, vertical and horizontal crosspieces (
11) and (12) can be formed integrally. In this case as well, it can be carried out by adding steps to the vertical and horizontal crosspieces (11) and (12) and stretching the sheet material (5) on the lower crosspieces.

When constructing a tiled roof using the tile beam assembly (10) of the present invention using the tile beam construction method, the roof surface (A) of a normal flat rectangular shape such as a gable roof is shown in FIG. Use the required number of rectangular assembly panels (lO) shown in Figure 5, and use the square assembly shown in Figure 1 or Figure 5 for hipped roofs, T-shaped roofs, and other roofs with ridges or valleys. This is carried out using the required number of crosspiece panels (10) and triangular assembled crosspiece panels.

First, as shown in Figure 7(a), the field board (4)
On the roof surface (A) on which the
Layout is performed according to the layout and a marking mark (22) is added, and a marking <23> is made in the direction of the roof slope at the required position of the mark (22).

At this time, in some cases, the roof surface (
A) A standard crosspiece or tile seat is fixed to the eaves or shrine by nailing.

After the above inking, as shown in Figure 7 [b], inking (2
3) In line with the lines and marks (22), the assembled crosspiece panels (10) are sequentially arranged side by side on the roof surface (A), and nailing means is applied to each predetermined location (mainly at the location of the lower crosspiece). etc. to fix it to the roof surface (A).

At this time, since the waterproof sheet material (15) is stretched on the lower surface of the assembled crosspiece panel (10), when the adjacent assembled crosspiece panel (1 (1)
0), one of the nokunel sheet materials (
The extending end (15a) at the side of (15) or (15)
b) and the end of the sheet material (I5) of the other panel are arranged and fixed side by side so as to overlap.

For example, at the joint between left and right adjacent panels, the extending end (15) of the sheet material (15) of one panel is
b) Place the sheet material (15) of the other panel on top,
In addition, at the joint between panels that are vertically adjacent in the slope direction, the upper side extending end (1) of the sheet material (15) of the lower panel
The assembly crosspieces (20) are arranged and fixed in parallel so as to butt against each other so that the flat end of the sheet material (15) of the upper panel is placed on top of 5a). As a result, the waterproof layer (5) made of the sheet material (I5) as a roof base can be laid simultaneously with the construction of the ridgepole without the risk of rainwater etc. intruding over the entire roof surface (A).

Therefore, by arranging the assembled crosspiece panels (1o) in parallel, not only can the vertical and horizontal crosspieces (11) and (12) be installed side by side at predetermined intervals over the entire roof surface (A), but also A waterproof layer (5) can also be installed as a roof base.

In particular, each of a plurality of vertical crosspieces (11) and horizontal crosspieces (12)
) and the sheet material that forms the waterproof layer can be handled as an integrated panel, and can be fixed side by side as they are, so each crosspiece can be
Compared to the case of arranging and fixing books one by one, tasks such as assignment, marking, arranging, and nailing on the roof surface can be greatly simplified.

Moreover, this assembly crosspiece (20) serves as a shape-retaining and holding frame for the sheet material ((5)) stretched thereon,
There is no fear that the sheet materials will be blown away by the wind during the parallel installation work, and the construction work can be carried out easily.

In addition, in the above construction method, the upper crosspiece is a vertical crosspiece (11)
If so, the sheet material (15) is attached at the bottom of the panel.
It is also possible to extend the end portion of the sheet material and overlap the end portion of the sheet material (i5) on the upper side of the panel adjacent to the lower side in the slope direction. In addition, an assembled crosspiece panel in which the sheet material (15) has an extending end (15b) on both the left and right sides of the panel, and an assembled crosspiece panel in which the sheet material does not have an extended end on both the left and right sides are used. The construction method of the present invention can also be carried out by arranging them alternately and arranging them in parallel.

Furthermore, by sequentially arranging the assembled crosspiece panels in parallel from the end of the roof surface (A), the above markings and reference markings can be omitted.

After the assembled timber panels (10) are arranged in parallel as described above, tile roofing is carried out in the same manner as in the conventional hooking timber construction method. In other words, the horizontal crosspiece (12) has a curved edge (
K1) and the engaging portions (K2) on the curved edge (K1>) may be sequentially arranged in parallel in the roof slope direction and the lateral direction while being locked on the longitudinal crosspieces (11>). Tiled roofs can be easily loosened.

In addition, by using the assembled crosspiece panel (lO) shown in Figure 5, a gap is created between the waterproof layer <5> made of waterproof sheet material (15) and the horizontal crosspiece (12) as shown in Figure 6. In addition, it can be installed in parallel with a waterproof layer (5
) can be laid at the same time as the construction of the piers.

Although not shown in the diagram, a tiled roof with an insulating structure can be constructed by interposing an insulating material such as synthetic resin foam over almost the entire surface between the upper crosspiece and the waterproof sheet material. can.

Furthermore, the present invention is applicable not only to the roof surface of a general wooden house in which the field surface is formed by field temporary construction as described above, but also to the roof surface of a general wooden house where the field surface is formed by laying a hard cement board on the main building material such as shaped steel. They can be used side by side in the same manner as described above on the roof surface of a field, or on the roof surface of a so-called RC field where mortar or the like is layered on an RC concrete slab to form a field surface.

In addition, the present invention can be suitably used for constructing tiles of various shapes such as S-shape as well as Japanese-style tiles, and can also be applied to roof re-roofing.

[Effects of the Invention] As described above, according to the construction method of the present invention, it is possible to easily construct the vertical and horizontal piers in a state where they are arranged side by side at predetermined intervals by simply arranging and fixing the assembled crosspiece panels side by side on the roof surface. Compared to the case where each crosspiece is installed and fixed one by one on top of the waterproof layer, the slope is lower. It is possible to greatly simplify various operations such as laying, allocating, marking, arranging, nailing and fixing the waterproof layer on the roof surface. Moreover, the juxtaposition of each crosspiece becomes straight, and the juxtaposition of the tiles secured to these crosspieces also becomes neat, making it possible to construct a tiled roof without requiring any skill.

In particular, in the present invention, by using an assembled crosspiece panel in which a waterproof sheet material is stretched on the lower surface of the assembled crosspiece, it is possible to fix the panels in parallel and to lay a waterproof layer of sheet material on the same IPj. There is no need to install a waterproof layer as a roof base separately from the construction of the crosspieces, and it can be laid over the entire roof surface simply by arranging the assembled crosspiece panels in parallel as described above, so it is naturally carried out. It can be easily installed using timber construction. Moreover, at the joints between adjacent panels, the extended end of the sheet material of one panel is overlapped with the sheet material of the other panel, so the waterproof layer can be laid without the risk of rainwater entering. .

Therefore, it is possible to significantly shorten the construction period for constructing a tiled roof, and also to improve the efficiency and rationalization of the construction work.

Further, according to the assembled crosspiece panel of the present invention, the vertical and horizontal crosspieces and the sheet material constituting the waterproof layer can be handled as a regular-shaped panel, making transportation such as carrying it up to the roof, installation work, and other handling easier. The assembled beams serve as a holding frame for sheet materials that are easily blown away by the wind, making work particularly dangerous in strong winds or on roofs with large slopes compared to when installing a waterproof layer alone. It gets easier.

The present invention can be suitably used for roofs made of wood, steel frames, or RC structures, and can also be applied to reroofing, contributing to rationalization of tile construction.
