Description

[Detailed description of the invention] (a) Industrial application field The present invention particularly relates to a metal core wood in the construction of a roof made of metal tile sticks.

(b) Conventional technology Wooden or vinyl chloride cores were used for the core of tile stick roofs, but in recent years fire-resistant structures have become more important, and metal cores such as stainless steel and iron have been used. Trees are needed.

This metal core is often used in the shape of a semicircle, which is made by cutting a pipe in half, and the predetermined positions for attaching the core to the field material are marked out at equal intervals perpendicular to the ridge. Then, a semicircular metal core is attached and a valley tile is roofed. At that time, the tops of the left and right rising walls of the valley tile are nailed to the metal core with tapping screws, and then the core is attached from above. It was covered with a cap.

(c) Problems that the invention aims to solve This roof with tile sticks is attractive because of the strength of the impressive mountain tiles that run from the ridge to the eaves. In order to produce such a powerful mountain tile, the center of the circle drawn by the mountain tile must be positioned above the field surface. If you don't do this, the mountain tiles will look like they're sunken between the valley tiles, and you'll lose the sense of volume and the powerful beauty.

In order to bring out the powerful beauty of mountain tiles,
For example, when using a wooden core, as shown in Figure 6, by nailing a half-round processed material 20 onto the rootstock 19 and adjusting the height of the rootstock 19,
The center of the circle drawn by the finished mountain tile was positioned above the field surface.

However, with conventional semicircular metal cores, unlike wooden cores, the height of the core cannot be adjusted, so the center of the circle drawn by the core is at the same position as the surface of the field material. Ta. As a result, the center of the circle drawn by the mountain tiles was in the same position as the surface of the field wood, and the mountain tiles appeared to be sunk between the valley tiles, losing their powerful beauty.

Also, when nailing valley tiles to a metal core, a tapping screw is used to cover the core with a cap, so the head of the tapping screw forms a convex portion on the surface of the core, as shown in Figure 7. This also made it look bad. Furthermore, in this case, if dissimilar metals are used, one of the metals will quickly deteriorate due to electrolytic corrosion. For example, if a copper roofing material is used, corrosion will often occur because copper is a very noble metal in the ionization series and the metals that come into contact with the copper are often base compared to the copper. For this reason, if the core cap and the tapping screw are in such contact that the head of the tapping screw forms a convex portion on the surface of the copper core cap, the tapping screw will corrode due to electrolytic corrosion. Generally for roofing materials
Tapping screws made of 18 chrome stainless steel are used, but since they are dissimilar metals, corrosion cannot be avoided if the contact is large.

Furthermore, in order to provide the strength of the semicircular metal core, it is necessary to use a thick one, which inevitably increases the cost.

The present invention aims to solve these problems.

(d) Means for solving the problem The present invention combines a core wood body and rib material.

The main body of the core wood is formed by providing recesses at the bottom of both sides of the arc-shaped part, hanging from both the left and right lower ends of the arc-shaped part to form side parts, and then bending both ends of the side parts outward. The metal plate is roll-formed to form a flange.

The upper side of the rib material draws an arc along the circular arc portion, and the portion facing the concave portion of the core body is cut out.

A metal core for roofing with tile rods is used, in which these ribs are installed at appropriate intervals inside the core.

(e) Action Mark out the predetermined position for attaching the core wood on the field material, arrange the core wood body along the marked line, and attach the screw that does not require a pilot hole to the flange (screws that do not require a pilot hole are It is a screw that can perform the three steps of drilling, tapping, and fastening in a single process.

A metal valley tile is laid between each core body, and the upper end of the valley tile is fixed to the recessed part of the core body using a screw that does not require a pilot hole, and a core tree cap is attached.

(F) Example A first example of the present invention will be described based on the drawings.

The core body 1 shown in FIG. 3 is formed by roll-forming a metal plate. Both sides of an arcuate portion 2 are bent inward to form hook portions 4, and the side portions 5 are made to hang down. A flange 6 is formed by bending both ends outward. A recessed portion 3 is provided which is recessed inward from the hook portion 4 of the arcuate portion 2.

The rib material 7 shown in FIG. 4 is made of a metal plate, and its upper side draws an arc along the arc of the arc-shaped part 2 of the core body 1, and the support upper surface that is bent and comes into contact with the arc-shaped part 2 8, and the part facing the recess 3 is cut out to prevent the rib material 7 from coming into contact with the screws that are driven when fixing the valley tile to the core wood. The rising portion 12 of the rib material 7 is bent to form a supporting side surface 9 that comes into contact with the side surface portion 5 of the core body 1. The lower end of the rib material 7 is bent to form a support bottom surface 10, and both ends of the support bottom surface 10 are extended to a length that allows the flange 6 of the core body 1 to be fitted. Then, both ends thereof are raised to form a holding portion 11.

The metal valley tile is curved downward, its both ends are raised up, and it is bent along the hook part of the core wood body 1.
Furthermore, the end portion is curved so as to overlap the recess 3 to form a rising wall 14 of the valley tile.

The core wood cap 15 draws an arc along the arc-shaped part 2 of the core body 1, and both lower ends thereof are bent to fit into the hook part 4 to form a fitting part 16, and its tip is lowered downward. Further, it is folded back inward to form an unnecessary folded portion 17.

When performing construction using the core wood body 1, rib material 7, core wood cap 15, and metal valley tile constructed as described above, first, a predetermined position for attaching the core wood to the field material is marked out.

Rib materials 7 are inserted into the core wood body 1 at appropriate intervals,
The holding part 11 of the rib material 7 is bent inward to sandwich the flange 6.

The core wood body 1 is arranged in line with the marking line, and it is fixed to the field material etc. using screws that do not require pilot holes on the flange 6. At this time, since the rib material 7 is attached to the core wood body 1, the core body 1 The wooden body 1 can be easily arranged and fixed on field materials without expanding or narrowing.

A metal valley tile is installed between each core wood body 1, and a rising wall 14 of the valley tile is stacked on the recess 3 and fixed with tapping screws.

In this way, metal valley tiles are successively laid on the roof.
Thereafter, by covering the core wood cap 15 and fitting the fitting part 16 into the hook part 4, the core wood cap 1 is closed.
5 to the core wood body 1.

Further, a second embodiment of a method of assembling the core wood cap 15 and the valley tiles using a hanger will be explained based on FIG. 5. Unlike the first embodiment, the core wood main body 1' does not have a hook portion 4, and has a circular arc-shaped portion 2 that draws an arc.
A metal plate is roll-formed so that concave portions 3 are provided below both sides of the circular arc portion 2, and are suspended from both left and right lower ends of the circular arc portion 2 to form side portions 5, and both ends thereof are bent outward to form flanges.

The rib members 7 of the first embodiment are fitted into the core body 1' at appropriate intervals, and the holding portions are bent inward to sandwich the flanges. Arrange the core wood body 1' in line with the marking line on the field material, and attach it to the field material or the main building material with screws that do not require pilot holes to the flanges, and then attach each core wood body 1' to the core wood body 1'. While roofing with a valley tile in between, the end barge part 18' of the hanger is engaged with the barb part 20 of the valley tile, and the hanger 18 is fixed in the recess 3 of the core body 1'.
Cover with the core wood cap 15, and fit the lower ends of the core wood cap 15 to the seam of the valley tile.

Incidentally, even without the presser portion 11, the rib material can be attached to the core body by fixing the flange 6 and the support bottom surface 10 with rivets.

(g) Effects of the invention With the conventional semicircular metal core, the height of the core cannot be adjusted. As a result, the center of the circle drawn by the finished mountain tile was in the same position as the surface of the field wood, and the mountain tile appeared to be sunk between the valley tiles, losing its powerful beauty. but,
The metal core wood for roofing tile sticks according to the present invention allows the height of the side part to be set according to the size of the valley tile and core wood cap, so the center of the circle drawn by the finished mountain tile can be adjusted. It can be positioned above the field level. In this way, the powerful and powerful beauty of mountain tiles can be expressed.

Furthermore, recesses are provided below both sides of the arc-shaped part, and when securing the valley tile to the main body of the core, the ends of the valley tile are overlapped in the recess and secured with tapping screws, and even when using a hanger. In order to secure the hanger in the recess, the tapping screw that secured the valley tile will be driven into the recess. In this way, the head of the tapping screw is hidden in the recess, and even when the core cap is covered, there is no problem of the head of the tapping screw creating a protrusion on the surface of the core cap.

In addition, since the tapping screw does not touch the core cap in this way, even if dissimilar metals are used for the core cap and the tapping screw, the problem of one being damaged quickly due to electrolytic corrosion is solved.

Regarding the thickness of the metal core, conventional semicircular metal cores were made of iron and required a thickness of 3.0 mm or more in order to provide strength, but the thickness of the metal core of the present invention for tile stick roofing Since the metal core wood has ribs that support and reinforce the core body, the core body has sufficient strength even with a thickness of about 0.8 mm to 1.0 mm. Therefore, it can be produced at low cost and provided at low cost.

The present invention can also be used in construction methods that do not require field materials.
