Description

[Detailed Description of the Invention] Conventionally, the roof construction method uses metal plates that are placed horizontally along the water slope of the roof, perpendicular to the rafters installed from the scale toward the eaves. In order to maintain waterproofness and strength, a hanger is hooked to the water return part of the roof deck and fixed with a presser hanger, and on top of that, a hanger is hooked to the lower edge of the roof board located on the upper level. A construction method is used in which the roof is assembled with horsetails and fixed in the upper direction of the Rvc.

The vertical joints of the horizontally-roofed roof boards are handled by combing them together or by butting the left and right roof boards together, laying water cutting boards on the base, and covering the 9M root surface with a joint cover. . But horizontal roof f! Rainwater easily ran down the roof, and rainwater easily leaked through the joints when a strong wind blew.

For this reason, the subsurface of the roof should be waterproof underlayment material + 2) 7 suf.
Waterproofing materials such as roofing are installed. However, in order to fix the roof shingles, the hangers are nailed directly through the waterproof board and fastened to the foundation, so when rainwater seeps from the storm surface of the roof, it soaks into the foundation through the nail holes, and both There were problems such as causing teeth grinding, further corroding the base, and reducing the strength Q of the building. In some cases, the roof panels are fixed at the top using molded metal rafters, but since holes are made in the rafters, it is impossible to prevent water from seeping in from that point. It had the disadvantage of being

The present invention addresses these five drawbacks and inconveniences, and relates to the structure of a completely waterproof roof made of thatch (thatch) without making any holes in the roof subsurface.

Examples will be described below with reference to figures.

A metal plate with a predetermined thickness, one width, and a length is jutted out horizontally from side to side over the entire length at the center in the longitudinal direction! A supporting rail 1 is formed by vertically projecting a protruding piece 2 having a flange forming a straight cross section, and bending the protruding piece 2 slightly downward to form a drain 3c (Fig. 1). The fixing metal fitting 4 has a holding piece 4b shaped to hold the upper flap 5a/:j3b of the support rail from both sides. When installing the hanger (Figure 2), if the hanger, support rail, and roof board are made of solid metal, prevent direct contact by pasting a film on the back of the fixing bracket in advance. Because you can.

Selection of materials used becomes easy (Figure 6).

The waterproof board 5 that is inserted between the support rails 1 has a St.
It has a fixed edge, and the periphery in the longitudinal direction has raised portions 5a, 5a that match the height of the support rail O protrusion, forming a U-shaped cross section (FIG. 3).

The roof plate 6 attached to the support rail 1 is a molded metal plate, and the upper side of the roof plate has a water return part 6a protruding from the roof surface in the longitudinal direction, which also serves as waterproofing, and the lower side of the roof plate is attached to the adjacent roof. The top side of the board is folded down toward the back surface of the roof board, and the end portion is further bent inward so that the top side of the board can be aligned with the 6 folds of the water return section (Fig. 4).

Examples of this roof panel will be described with reference to FIG. 5 to the second section.

The support rail 1 is installed at a place such as the main building of a building frame, at 6 degrees from the roof surface of the base of the roof, at equal intervals of 1 m parallel from a to the eaves.
Several strips are firmly fixed to the base flange 3a of the support rail L1 using fasteners 9 such as screws or nails. If one length is insufficient from the support rail counterfeit ridge to the eaves, insert the small n of the support rail 1 from the top and bottom of the fitting groove 12a of the fitting 1-12 as shown in Figure W410 and the second part to the desired length. can be inherited. In this case, the sealant is filled with a sealant to make it waterproof.

After fixing the support rails, attach the support rails l, ll[,
The waterproof board 5 is inserted in a fitted state and installed from the first type to the eaves without any gaps. If the waterproof board is short compared to the flow of the roof, make a waterproof board of any length by making the upper and lower overlapping allowances sufficiently long and sealinking the waterproof board to the overlapped part. The nails and holes drilled in the base flange 3a in order to fasten the support rail 1 to the base structure 8 are completely covered by this waterproof board 5 and do not appear on the surface of the roof 9, and are attached to the roof base in the form of a waterproof sheet. is formed, creating a completely waterproof base (Figure 5).

Horizontal roofing boards 6 are installed on the roof subsurface installed in this way.
is placed horizontally at a predetermined position perpendicular to the support rail 1, and the hanger block of the fixing fitting 4 is firmly hung on the water return part 6a of the upper side, and the upper part of the support rail 10 is held by the holding piece 4b. :,
/e3b is bent and fixed with a decoy that holds it from both sides (Fig. 7).Since the support rail P also serves as a support rail, the position of the fixing metal fittings will not shift, and the roofing should be done accordingly.

A beautiful roof without distortion can be constructed.

In addition, the flap 6b on the lower side of the upper roof sheet 6 is assembled and hooked onto the water return portion 6a of the lower roof sheet 6, and the lI of the fixing metal fittings 4 is installed in the same manner as described in 1liI. Hang one piece 4a, stop it, and raise it in the WA direction (Figure 8).For the vertical joint of the roof board 6Q, assemble the joint part of the two adjacent boards in the center of the support rail. A method is used in which a joint cover is separately assembled on the roof surface with a joint cover or a joint cover that is butted together. in this case,
Since the roof subsurface is in the same condition as the rain gutter, it has good drainage and is completely waterproof, so there is no need to lay a patch board such as a drainage board on the lower floor as in conventional construction methods, and the roof board can be directly installed. It is possible to save 0 work steps and materials used.

8. Do not use nails or other fasteners to fix the roof panels directly to the main body.
Because it is a construction method in which the nails are fixed with 100mm bolts, even if the vibration of the building or the thermal expansion of the base material occurs, the force can be absorbed at the fixed point, so the nail hole does not become large and the strength does not decrease as with conventional construction methods. The effect on roof shingles can be determined.

As shown in Fig. 9, the support rail has a two-tiered structure, with a heat material 1 such as a wood wool t-ment plate placed on the base plate 5/3a.
0, and the above-mentioned waterproof board 5 can be used for insulation.

A soundproof roof can be created, and since an appropriate ventilation layer can be created between the roof subsurface and the roof shingles, it is also effective in preventing dew condensation on the back side of the roof shingles.

The roof is made of blue shingles to prevent wind and rain, but even if water leaks from the overlapped seams of the shingles to the back of the shingles, there is a drain 3c at the tip of the upper flap of the support rail, so white water will not drain away. The waterproof board is placed on the surface of the waterproof board 5, and plays the same role as a rain gutter, draining water immediately from the house toward the eaves, so it has a double waterproofing effect and is safe. Insulation material on the back side of the board
If it is built into a shape that can be incorporated, it will also be effective in insulating the roof and reinforcing the roof shingles.

With this roof construction system, the spacing of the support rails and the width of the waterproof board can be adjusted to match the length of the roof for any roof with IA construction, and the width of the waterproof board can be adjusted accordingly. They can be installed at arbitrary intervals, and when it comes to the working width of the roof board, the zero position can be determined by freely sliding the fixing fittings in the longitudinal direction of the support rail. , the shape of the water return part that is fixed 1IJr'lJr of each roof board.

By shaping it to match its size.

It has a wide range of application as it can be used commonly.

The materials used are support rails, Ii! iI fixed fittings and roof plates are molded metal plates such as galvanized iron plates, colored iron plates, stainless steel, and aluminum. As long as the waterproofing board has excellent waterproofness and corrosion resistance, it does not require much strength, and a metal product such as a synthetic resin board or an aluminum board can be used.
