Description

[Detailed Description of the Invention] The present invention relates to a roof structure having an effect of preventing falling snow.

Traditionally, in snowy areas, to prevent accidents caused by falling snow from roofs, snow stoppers and rod-shaped snow stoppers (angles, pipes, logs, square timbers), etc. are fixed to roof tile bars, crevices, rafters, etc. In the case of roofs with tile sticks, angles 12 are fixed to tile sticks 11 as shown in Fig. 1, but these tend to damage the roofing material and cause water leakage because the load is concentrated on the attachment point. This was not very desirable from the standpoint of design and the ability to maintain footholds during snow removal. However, in snowy areas, prevention of falling snow is stipulated by local ordinances and is an inspection item for buildings.
There was a strong desire for improvements to snow stoppers, etc.

Therefore, the inventor of the present invention repeatedly conducted research to solve the drawbacks of the conventional methods, and found that installing a separate snow stopper on the roof after construction damages the roofing material and spoils the aesthetics, and that snow stoppers are not installed on the roof itself. They discovered that these drawbacks could be overcome by making it more effective, and devised the present invention.

In other words, the present invention is applicable to a roof structure in which long metal roofing materials are covered in parallel with the crosspieces in the longitudinal direction on a sloped roof with crosspieces installed at predetermined intervals on the roofing board. The part has a rising part that is bent upward at the part located closest to the ridge, or has a ridge-side folded part that is folded back 180 degrees upward from the part located closest to the ridge, and is a crosspiece. The part that touches the top surface is nailed with a nail fitted with a washer, and the eave side part of the roofing material is attached to the ridge side of the crosspiece and the ridge side part of the eave side roofing material nailed to the crosspiece. The folded part of the eave side that is in contact and bent downward by 180 degrees is connected to the folded part of the eave side of the washer attached to the nail that is nailing the roofing material on the eave side or the folded part of the ridge side of the roofing material on the eave side. To provide a roof structure that utilizes crosspieces, which are characterized by being stopped, as a snow stopper.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a roof structure using crosspieces according to the present invention as a snow stopper will be described in detail based on embodiments shown in the drawings.

FIG. 2 is a perspective view of an embodiment of a roof constructed using a roof structure that uses crosspieces according to the present invention as a snow stopper, and FIGS. 3 and 4 respectively show
End views showing different embodiments in an X-ray cross section,
Figures 5 to 8 show various embodiments of roof structures that utilize the crosspieces according to the present invention as snow stoppers.
is a cross-sectional explanatory view perpendicular to the crosspiece, B is a perspective explanatory view,
FIG. 9 is a perspective view showing a method of connecting longitudinal ends of the roofing material.

In the drawing, reference numeral 1 indicates a roof sheathing board, which is constructed by waterproofing the top surface by asphalt roofing or the like, as in the past. 2 are crosspieces installed almost parallel to the ridge on the roof board 1 at predetermined intervals of 20 to 100 cm, and are installed at eaves to improve drainage of melted snow and rainwater flowing on the metal roofing material, which will be described later. against 1/10
It is preferable that it is provided diagonally with a slope of 0 to 1/50. 3 is a long metal roofing material whose longitudinal direction is parallel to the crosspiece 2;
The ridge-side portion 3a has an upwardly bent rising portion at the most ridge-side portion as shown in FIGS. It has a ridge-side folded part 3a that is folded upward by 180 degrees from the side part, and is nailed to the top surface 2a of the crosspiece 2 with nails 4 fitted with washers 5. 3 eave side part 3
b is a fifth eave-side folded portion 3c that is in contact with the ridge side surface 2b of the crosspiece 2 and the ridge-side portion 3a of the eaves-side roofing material 3 nailed to the crosspiece 2 and bent downward by 180 degrees. As shown in Figures 7 and 7, a washer 5 attached to a nail 4 nailing the roofing material 3 on the eaves side is fixed to the eaves side, or as shown in Figures 6 and 8, It is locked to the ridge side folded portion 3d of the side roof material 3.

The length of the ridge-side folded portion 3d of the roofing material 3 or the eave-side length of the washer 5 is determined by the angle of the roof, the ease with which rainwater is blown up by typhoons, etc.

As shown in FIG. 3, this roofing material 3 has a structure in which almost the entire surface of the central portion 3f between the portions that abut on the crosspieces 2 on both sides parallel to the longitudinal direction is in contact with the roofing board 1. In addition to this, as shown in Fig. 4, there is also used a structure that has a part in the center of the central part 3f between both sides parallel to the longitudinal direction that comes into contact with the ridge side 2b and top surface 2a of the crosspiece 2. can. It is preferable that this roofing material 3 be covered in one piece from end to end, but if it is necessary to connect them, they can be connected using metal tape 6 or the like as shown in FIG. At the same time, it is good to have a water-stop effect, and if the building is large and the distance from one end of the roof to the other is long and the roofing material 3 is covered with a through-hole, the rain gutter installed at the longitudinal end of the roofing material 3 is If the amount of water flowing into the roof 7 becomes too large, it is preferable to install gutters running from the ridge to the eaves at appropriate intervals in the middle of the roof, as shown in FIG. An end plate member (not shown) is fixed to the side end of the roofing material 3 facing the rain gutter 7 so that the crosspiece 2 is not exposed, and the gap between the end plate member and the roofing material 3 is filled with caulking material. Just seal it. Furthermore, if the nail holes 3e through which the nails 4 penetrate when nailing the roofing material 3 are made as elongated holes in the longitudinal direction of the roofing material 3, thermal expansion and contraction of the roofing material 3 due to temperature changes can be absorbed. It is preferable because it can be bent, and each bending and folding part is 3 to 3 times thicker than 0t bending, where the plate thickness is
It is preferable to bend by 20t because there is less damage to the coating film or coating layer.

When a roof structure using the crosspieces according to the present invention as described above is used as a snow stopper, the structure has the following advantages and is of great practical value.

A: Snow that has fallen on the roofing material gets caught on the ridge side of the crosspiece and does not slide down to the eave side, ensuring a reliable snowfall prevention effect.

B. Because the crosspieces are installed at specified intervals across the roof, the force is not applied only to the fixed part of the snow stopper, as is the case when using conventional snow stoppers, but the force is applied evenly to the entire roof. Therefore, the snow load capacity is reasonable.

C. Since the snow stopper does not have to be installed on the roof later, the design can be much improved.

D: There is no snow stopper installed on the roof that could cause damage, so there is no risk of water leakage.

E Since almost the entire surface of the roofing material is in contact with the crosspieces or field boards, it can be used as a foothold when removing snow.

F. Since the structure is such that the snow stopper is not installed on the roof, there are no protrusions on the roof that would pose an obstacle when removing snow.

G The structure is such that the eave side part of the ridge side roofing material covers the ridge side part of the eave side roofing material to be nailed, so it is good for rain protection.

H: Molding is simple, and difficult construction techniques are not required.
