Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roof construction method that can be easily and quickly constructed using a roof board in which tensioning through holes and fastening through holes have been drilled in advance.

Conventionally, in order to construct a roof using folded roof sheets, the length of the roof sheet in the longitudinal direction ranges from relatively short (about a few meters) to long span (about 50 meters).
Most of the above) are installed on-site with holes drilled and bolts, nuts, etc. When holes were drilled on site in this way, the positions were often misaligned, and some holes were incomplete because the work was done on roofs with poor footing. In particular, for long-span roof panels, it is actually impossible to drill holes in advance because a roof panel forming machine is installed on site and coiled metal plates are processed there to form the roof. Although the long-span roof shingles are reliable against rain, they require many workers, and for example, it takes a lot of time to position them in the longitudinal direction. The construction work was inefficient considering the size of the project.
In view of this, the applicant made the length of the roof plate relatively short in the longitudinal direction, provided a joint part, and conducted research and development to ensure that the joint part can be closed in the rain.

Therefore, the roof construction method of the present invention was invented to more efficiently perform roof construction using roof sheets. Furthermore, the present invention solves the problem that a roof board that has all holes drilled cannot be constructed at a site where the pitch between the structural members is appropriately different.

Next, the construction method will be explained using drawings and the like. First, to describe the roof plate A and other constituent materials used in this roof construction method, the roof plate A consists of a peak part 1 and a valley part 2, which are continuous in the width direction,
Appropriate length in the longitudinal direction (for example, about 5 m to about 20 m
m). The peak portion 1 and the valley portion 2 are divided by the neutral plane of the roof board A, and the upper side is referred to as the peak portion 1 and the lower side is referred to as the valley portion 2. The mountain portion 1 has a trapezoidal mountain shape in cross section, and the valley portion 2 has a bottomed V shape. In addition, the roof plate A may have peaks 1 and 1 formed on both sides of one valley 2 (see Figures 1 and 8), or a plurality of peaks 1 and valleys 2 may be formed alternately. Sometimes it is done. Tensioning through holes 3, 3 are bored in the top surfaces 1a, 1a of the mountain portions 1, 1 on the water side (right side in FIG. 2) of the roof plate A. The top surfaces 1a, 1a of the outer peaks 1, 1 are provided with fastening holes 4,
4... are drilled in large numbers at regular intervals. The tightening through-hole 3 and the tightening through-hole 4 are also drilled in advance at the factory. Here, the fastening through hole 3 is for attaching a bolt 12 of the roof bracket 9, which will be described later, and the fastening through hole 4 is for attaching a bolt and nut 13, which will be described later, between the top surfaces 1a and 1a. be. Reference numeral 5 denotes an upward step, which is provided at the water side (right side in FIG. 2) end of the roof board A. Reference numeral 6 denotes a downward step, which is provided at the end of the roof board A on the water side (the left side in FIG. 6).
The upward stepped portion 5 and the downward stepped portion 6 are the joint portion 1 which will be described later.
5, and there is a downward step 6 on the water side end of the roof board A located on the eaves side of the roof.
is not provided, a trailing portion 7 is formed, and, although not shown, an upward step portion 5 is not provided at the water side end of the roof plate A located on the ridge side of the roof. A plurality of structural members 8 are provided on the upper part of the structure at predetermined intervals in parallel to the eaves. Reference numeral 9 denotes a roof bracket, which is composed of a chevron portion 10 and a bottom portion 11, and has a tip-shaped bolt 12 protruding from the top portion 10a of the chevron portion 10. It has the above-mentioned structural members, and next, to describe its specific construction method, the mountain part 1 on the water side of the roof board A is connected to the mountain part 9 of the roof bracket 9 on the structural member 8 at an appropriate position. 10, and insert the bolt 12 through the fixing hole 3 of the crest 1 on the water side (see Fig. 2). Then, bolts 12, 12... (second
(in the figure, the left side and the middle) are positioned and penetrated onto the top surface 1a of the mountain portion 1 (see FIG. 4). In the embodiment, at the tip of the bolt 12 of the roof bracket 9,
A pipe a having an inner diameter slightly larger than the outer diameter of the bolt 12 is driven into the part where the top surface 1a of the mountain part 1 protrudes slightly upward (positioning), and a hole is drilled as shown in FIG. Then, an adjacent roof panel A is placed parallel to the roof panel A thus constructed. That is,
Place the peaks 1, 1 so that their top surfaces 1a, 1a overlap, align the upper and lower fastening through-holes 4, 4, insert them, and screw them with the bolt/nut 13 (fifth (see figure). Further, nuts 14 are screwed onto the bolts 12 protruding from the top surface 1a (excluding the bolts 12 at the joint portion 15 on the water side, which will be described later).
(see figure). In this way, the lowermost roof, that is, the roof on the eaves side is constructed. Then, the bolts 12 on the tops 10a of the chevrons 10 of the roof brackets 9 of the structural members 8 are inserted into the bolts 12 of the roof brackets 9 of the structural members 8 at appropriate positions (see Fig. 6). reference). and,
As mentioned above, the bolts 12, 12 of the roof brackets 9, 9 located on the lower surface of the same roof board A are positioned and passed through the top surface 1a of the angular part 1, and the bolts 12, 12, . . . Plate A is installed side by side, the top surfaces 1a, 1a are overlapped, and the upper and lower fastening through holes 4, 4 are aligned (see FIG. 7). And Boruto Natsu 13
Nuts 14 are screwed onto bolts 12 protruding from the top surfaces 1a and 1a (excluding bolts 12 at a joint portion 15 on the water side, which will be described later). Here, a joint part 15 having a gap is formed by the lower end of the upper roof panels A, A and the upper end of the lower roof panels A, A (on the eaves side).
Repeat these steps sequentially on the ridge side to construct the roof.

In the above explanation, the tensioning through-hole 3 was bored in the top surface 1a of the peak 1 on the water side of the roof board A. Top surface 1 of part 1
Even if holes are to be made in point a, the construction method is the same as described above. In the figure, 16 is a wall.

Next, the effects will be explained.

In the present invention, the length in the longitudinal direction of the roof plate A consisting of the peaks 1 and the valleys 2 is set to an appropriate length, and the top surface 1a of the peaks 1, 1 near one end in the longitudinal direction,
Tightening through holes 3, 3 are bored in 1a, and the top surfaces 1a, 1
A large number of fastening through holes 4, 4... are drilled at regular intervals in other parts of a, and roof brackets 9 are fixed to a plurality of structural members 8 of the structure at appropriate positions on the structural member 8. By inserting the fixing hole 3 of the roof plate A into the bolt 12 on the top 10a of the chevron part 10 of the roof bracket 9 and screwing the nut 14, the roof plate A of an appropriate length can be attached. Longitudinal positioning can be easily done through the tensioning through-holes 3, which makes it possible to neatly align the tips of the eaves and ridge side edges after roofing. Working on roofs can be made especially safe by stopping the machine reliably at any point. In addition, after inserting the bolt 12 into the tensioning through hole 3, the roof bracket 9 located on the lower surface of the same roof plate A is inserted.
By positioning the bolt 12 so that it passes through the top part 1a of the mountain part 1, even if the spacing between the structural members 8, 8 varies depending on the site, the same roof plate A It can be roofed at any site and has versatility, and the positioning of the through hole 3 is automatically determined by the presence of the tensioning through hole 3, and it can be done easily and quickly using pipe a etc. .
In this way, by drilling the tensioning through-hole 3 in advance in the top surface 1a near one end in the longitudinal direction, not only good workability but also safe workability can be ensured. Furthermore, the top surfaces 1a, 1a of the peaks 1, 1 of the adjacent roof panels A, A are screwed together with bolts and nuts 13 through pre-drilled fastening holes 4, 4. The vertical positions of the fastening holes 4, 4, etc. are precisely aligned, and there is no need for the holes to be misaligned or incompletely drilled as in the conventional case, and the screwing work of the bolts and nuts 13 is also simplified. It can be done quickly and the screwing area can be made waterproof. In addition, by sequentially roofing such roof panels A from the eaves side so that there is a joint part 15 at the edge of the upper and lower roof panels A, it is possible to handle the roof panels A of an appropriate length. is good, and unlike long-span roof construction,
Roofing can be done with a minimum number of workers, and in addition to the above-mentioned excellent workability, construction costs can be reduced.
