Abstract

PURPOSE:To simplify repair work by securing a support piece to a bottom portion of a corrugated slate roof, placing a newly installed roof slate on the old roof, and connecting opposing curved portions of neighboring newly installed roof slates together via the support piece. CONSTITUTION:Support pieces C are secured at specified intervals on the bottom portion 2 of an existing corrugated slate roof A. A new roof slate B is placed on the corrugated slate roof A with the top and bottom portions 3 and 4 of the slate B respectively placed on the top and bottom portions 1 and 2 of the slate A. Curved portions 5 for connection of the neighboring roof slates B are connected to each other via the support piece C. This makes it possible to simply repair the roof while retaining the function of a building without removing the corrugated slate roof A.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention enables the construction of an existing corrugated slate roof while leaving the existing corrugated slate roof as is.
This invention relates to a repaired roof on which a new roof can be constructed.

[Prior art and its problems] Conventionally, corrugated slate roofs have existed, but
If these become old or corroded after long-term use and rainwater enters the room, it becomes necessary to replace the roof with a new one, and the existing roof must be removed and replaced with a new roof. Was.

During this removal, it is important to protect equipment, products, etc. at companies, factories, etc., as dust may accumulate during removal, piles of parts such as removed groove plates may fall, and the interior may leak in case of rain. Because of the tent.

It was necessary to put up tents, etc., and furthermore, the work and operations of companies, factories, etc. had to be temporarily suspended, and the losses and damages inflicted on companies and factories were enormous.

In addition, in gymnasiums, it is not recommended to install tents, etc., because if the floor surface leaks from rain, many slip accidents occur during competitions, or the floor surface warps, making it impossible to hold official competitions. It was mandatory.

In addition, if re-roofing work is carried out on ordinary houses while the residence is still occupied, there is a possibility that the roof will be exposed to rain, and the areas that have been removed must be re-roofed on the same day.
The work was inconsistent (it had the drawbacks of being troublesome and having poor work efficiency.

In either case, it takes time and effort to remove the existing roof,
Furthermore, it not only halts operations at companies, factories, etc., but also increases the number of days needed to install a new roof and increases construction costs, among other disadvantages.

[Means to solve the problem] Therefore, the present invention has been devised to solve the above problems.

As a result of repeated research, the invention was developed by fixing supports at predetermined intervals to the valleys of an existing corrugated slate roof, which has alternating arc-shaped valleys and arc-shaped peaks. Newly installed troughs with approximately the same shape as the troughs of the roof, and new crests with approximately the same shape as the ridges of the roof alternately, and a protrusion that bulges upward from the top along the longitudinal direction of the newly installed crests. The newly installed peaks and the newly installed troughs are placed above the ridges and the newly installed troughs are above the troughs, respectively! 3! By installing a new roof sheet on top of the corrugated roof and fixing the opposing bends of the adjacent new roof sheet to a support, the new roof was covered with a repaired roof. This solves the above problem by allowing a new roof to be built on top of the roof while leaving it as it is.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 6.

The roof is an existing corrugated slate roof made of slate 1 and lumber, and arc-shaped peaks 1 and arc-shaped troughs 2 are alternately and continuously formed in a substantially sine curve shape. Here, as shown in FIG. 2, the upper side of the neutral axis CC is referred to as the crest 1, and the lower side is referred to as the trough 2.

B is a newly installed roof, and includes a plurality of newly installed roof panels B.

B1. It is composed of... The new roof board B.

In this case, newly installed peak portions 3 and newly installed valley portions 4 are continuously formed alternately. The newly installed crest 3 has a shape that is substantially the same as the ridge 1, and the newly installed trough 4 has a shape that is substantially the same as the trough 2. The newly formed peak portion 3 can be superposed on the peak portion 1, and the newly formed valley portion 4 can be superposed on the valley portion 2 in a substantially intimate manner. A protruding portion 3 a is formed at the top of the newly installed mountain portion 3 to bulge upward along the longitudinal direction of the newly installed mountain portion 3 . The protrusion 3
Inside a, the existing corrugated slate roof A is covered with structural material 12.
The protruding parts of fixing tools S such as bolts and nuts for fixing roofing are housed therein.

Further, a connecting bending portion 5 is formed outward from the top portion of the newly installed mountain portion 3 at the outermost end. As an embodiment of the connecting bending part 5, a rising piece 5b is formed from the outer end of the horizontal piece 5a, a top piece 5C is formed inward from the upper end of the rising piece 5b, and an edge of the top piece 5C is formed. A hanging piece 5d is formed. An upwardly inclined edge 5e is formed on the side of the rising piece 5b from the lower end of the hanging piece 5d.

B2 is a cap material, and fitting portions 7.7 are formed from both ends of the upper surface portion 6 in the width direction.

8. Support lower part 9
and a tongue piece metal fitting 10.

A linear elongated hole 8a is bored in the support upper part 8.

Further, the support lower part 9 is extended from both ends in the width direction of the arcuate bottom part 9a.
Rising side parts 9b, 9b are formed, and rising side parts 9b, 9
Locking portions 9c, 9c are formed at the upper end of b. The locking portions 9c, 9c are configured to be fixed to the support upper portion 8 at appropriate locations. The tongue piece metal fitting IO has tongue pieces 10b, 10b formed from the upper end of the arcuate bottom part 10a, the arcuate bottom part 10a is fixed to the arcuate bottom part 9a of the lower support part 9, and the tongue pieces 10b, 10b are attached to the linear shape of the upper support part 8. long hole 8
It is configured to protrude outward from point a.

The fixing device 11, such as a bolt, a nut or a drill screw, can be adjusted appropriately between the tongue lOb of the support C and the approximately center point of the arcuate bottom 9a of the lower support 9. The reason for this structure is that the existing corrugated slate roof A, which serves as the base, has a predetermined length, and this extends in the longitudinal direction (
For example, from the eave side to the line side, multiple slate roof panels are attached to each other, overlapping at the ends, but in reality, if you look at the unit slate roof panels in the longitudinal direction, they are attached in a meandering manner. In order to correct the meandering, as shown in FIG. 6, the support upper part 8 is installed so as to be appropriately shifted in the left-right direction with respect to the support lower part 9.

First, a support C is fixed to a structural member 12 such as a main building that supports an existing corrugated slate roof A using a fixing device 11.

Next, the newly installed roof board B is placed between the adjacent supports C3C &
3iU will be given. At this time, the new crest 3 is closely superimposed on the ridge 1, the new trough 4 is tightly overlapped with the trough 2, and the protruding strip 3a formed at the top of the new crest 3 is attached to the existing corrugated slate roof A. A fixing tool S protruding from the peak 1 of is housed.

〔Effect of the invention〕

In the present invention, the supports C are fixed at appropriate intervals within the valleys 2 of an existing corrugated slate roof A in which arc-shaped valleys 2 and arc-shaped peaks 1 are alternately continuous. Newly installed troughs 4 having approximately the same shape as the troughs 2 of the corrugated slate roof and newly installed peaks 3 having approximately the same shape as the peaks 1 are alternately continuous, and the new ridges 3 are aligned along the longitudinal direction of the new ridges 3. The newly installed peak part 3 of the newly installed roof board B1 is formed with a protruding strip 3a that bulges upward from the point, and connecting bent parts 5, 5 are formed at both ends in the width direction, at the peak part l-hi,
Newly installed troughs 4 are each placed on top of troughs 2, and a new roof board B1 is installed on the corrugated slate roof A, and the adjacent new roof board B is installed.
, B, by fixing the opposing connecting bends 5.5 to the support C to make the new roof B into a repaired roof.
Firstly, it is possible to construct a new roof B that is approximately the same as the existing corrugated slate roof A, and secondly, the new roof B can be made stronger.

To explain these effects in detail, first, the existing corrugated slate roof A has alternately continuous arc-shaped valleys 2 and arc-shaped peaks l, and the new valleys 4 and new peaks 3 alternately. A new roof board B, which is continuous and has a protruding strip 3a that bulges upward from the top part along the longitudinal direction of the newly installed mountain part 3, and connecting bent parts 5, 5 at both ends in the width direction, That valley part 2
Since the new trough 4 and the new trough 4 are approximately equal, and the crest 1 and the new crest 3 are approximately equal, the upper and lower parts can overlap as a whole. Slateffl+1! Even if A becomes brittle, the corrugated slate roof A is hard to be damaged and has the effect of being made strong.

That is, since the cross sections of the corrugated slate roof A and the new roof B are approximately equal, the corrugated slate roof A has
This will support the newly constructed building IB, and this will support the load in an evenly distributed manner over the entire surface.As a result, even if the corrugated slate roof A is extremely brittle, the material of the corrugated slate roof A will not be easily damaged, and will be strong. There are advantages that can be achieved.

As mentioned above, the existing corrugated slate roof A, which has become extremely fragile due to aging, will remain as is, while the new roof C will be constructed.
The greatest effect is that it can be constructed easily and quickly, and that it prevents damage to the existing corrugated slate mill.

In addition, even if the new roof C and the existing corrugated slate roof A overlap, and even if the upper part of the fixing tool S to which the corrugated slate roof A is attached protrudes above the peak part 1, the protruding strip 3
The new building Ic can be roofed in an orderly manner.

Furthermore, in the present invention, since the existing corrugated slate roof A is repaired (renovated) as it is, it naturally has the advantage of being able to be constructed without disrupting the functions of the building (factory, company gymnasium, etc.).

In particular, the present invention provides a new roof B that has the same cross-section as the existing corrugated slate roof A, so when roofing is done in an overlapping state, the vertical spacing is small, making it easier to attach to the existing corrugated slate roof. There is also the advantage that there is no need to change or change the installation of devices and components such as ventilation systems and windows that were installed when the system existed.
