Abstract

PURPOSE:To simplify repair work of a roof by securing a support piece at the bottom portion of a corrugated slate roof, disposing a newly installed roof slate having a bottom portion with a curvature radius smaller than that of the bottom portion of the corrugated slate roof on the bottom portion of the corrugated slate 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 at an arcuate bottom portion 2 of an existing corrugated slate roof A. A newly installed roof B is disposed by placing an arcuate bottom portion 4 on the bottom portion 2 of the corrugated slate roof A. The bottom portion 4 of the roof slate B is formed with a curvature radius R1 smaller than the curvature radius R2 of the bottom portion 2 of the corrugated slate roof A. On both ends in the width direction of the roof slate B are provided curved portions 5 for connection. The opposing curved portions 5 of the neighboring roof slates B are connected to each other via the support piece C. This makes it possible to place the roof slate B without removing the corrugated slate roof A and to repair the roof simply while retaining the function of a building.

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.

[Conventional technology and its problems]

Traditionally, corrugated slate roofs have existed,
If these become dilapidated or corroded after long-term use, allowing rainwater to enter the room, it will be necessary to replace the roof with a new one. The roof was being reroofed.

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. Therefore, it was necessary to set up a tent roof 55, etc., and furthermore, the work or operation 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, 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 essential to lay a

In addition, in -C houses, if reroofing work is carried out while the residence is still occupied, there is a possibility that it will be damaged by rain, and the removed areas must be replaced with a new roof on the same day.
The disadvantage was that the work was inconsistent, cumbersome, and inefficient.

In either case, it takes time and effort to remove the existing roof,
Furthermore, there were disadvantages such as not only halting business operations at companies, factories, etc., but also increasing the number of days required to install a new roof and making the construction cost relatively high.

[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, in which arc-shaped valleys and arc-shaped peaks continue alternately. An arc-shaped newly installed roof board having a bottom portion and a chevron-shaped portion, the curvature of the arc-shaped bottom portion being smaller than the curvature of the valley portion of the corrugated slate roof, and connecting bent portions formed at both ends in the width direction. The bottom is in the valley of the corrugated slate roof! ! The new roof was installed on top of the corrugated slate roof, and the opposing connecting bends of the adjacent new roof sheets were fixed, and the new roof was covered with the repaired roof, allowing the existing corrugated slate roof to remain as it was. Then, a new roof can be built on top of it, which solves the problem mentioned above.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 7.

A is an existing corrugated slate roof, which is made of slates 1 to 1, and has arc-shaped peaks l and arc-shaped valleys 2 that are alternately formed in a continuous substantially sine curve shape. Here, as shown in FIG. 2, the upper side of the neutral axis cc is referred to as the crest l, and the lower side is referred to as the trough 2.

B is a newly installed roof, and B is a plurality of newly installed roof boards.

It is composed of The new roof board B1 has chevron portions 3 and arcuate bottom portions 4 formed in succession alternately, and a connecting bent portion 5.5 is formed from the outer end of the top portion of the chevron portion 3 on the outermost side. (See Figure 3).

The newly installed roof board B, as shown in Figures 2 and 3,
Three chevron parts 3, 3. . . . In addition to the embodiment in which connecting bent portions 5, 5 are formed from the top portions of the chevron portions 3, 3 on both outer sides, four or more chevron portions as shown in FIG. 3.3. ...may consist of more than one. In these cases, the chevron portions 3.3 on both outer sides have a shape divided into about half of the center side. In addition, the arcuate bottom 4
is formed so that its curvature R1 is smaller than the curvature R2 of the valley portion 2 of the existing corrugated slate roof A, as shown in FIG. Specifically, a substantially central portion of the arcuate bottom portion 4 can come into contact with the surface of the valley portion 2 . Moreover, the chevron portion 3 is formed higher than the chevron portion 1 of the corrugated slate roof A, and by pressing the chevron portion 3 of the newly installed roof board B1 downward, the chevron portion 3 opens outward, as shown in the figure. The arcuate bottom portion 4 is configured to be able to come into contact with the center of the valley portion 2 at the same time.

Alternatively, when the chevron portion 3 is slightly open outward,
By attaching the new roof plate B to a support C, which will be described later, the chevron portion 3 is appropriately shortened in the width direction, and the arcuate bottom portion 4 can come into contact with the valley portion 2.

The connecting bent portion 5 is a piece 5 that rises from the outer end of the horizontal piece 5a.
b is formed, and an inclined piece 5c is formed downwardly inward from the upper end of the rising piece 5b. A folded edge 5d is formed on the rising piece 5b side from the lower end of the second piece 5c.

B2 is a cap material, and fitting portions 7 are formed at both ends of the upper surface portion 6 in the width direction.

Reference numeral C denotes a support device, which is composed of an upper support portion 8 and a lower support portion 9. The support upper part 8 has side parts 8b, 8b rising from both ends in the width direction of an arcuate support bottom 8a having a flat valley-shaped cross section, and tongue pieces 8c, 8c extending outward and downward from the upper ends of the rising side parts 8b, 8b. has been done. Its rising side 8b
, 8b, the folded pieces 8d, 8 are folded outward from both ends in the front and back direction.
d is formed. The support lower part 9 extends from both ends in the width direction of the arcuate support bottom part 9a having a flat valley-shaped cross section to support side parts 9b.

9b is formed, and horizontal support top portions 9c, 9c are bent outward from the upper ends of the support side portions 9b, 9b. The arcuate support bottom portions 8a, 9a have a radius of curvature similar to that of a roadway, and are configured to have a radius of curvature equal to or slightly smaller than the radius of curvature of the valley portion 2 of the existing corrugated slate roof A.

The support upper part 8 is installed inside the support lower part 9, and the support side parts 9b, 9b of the support lower part 9 are locked with the folded pieces 8d, 8d formed on the rising side parts 8b, 8b of the support lower part 9. Both are in a polymerized state. At this time, the upper half of the rising side portions 8b, 8b of the lower support portion 9 is exposed upward. Configured like this,
The existing corrugated slate roof A that serves as the base is of a specified length,
A plurality of these are attached in a longitudinal direction (for example, from the eaves side to the line side), overlapping at the ends, but in reality, when looking at the unit slate roof panels in the longitudinal direction, they are attached in a meandering manner. In order to correct this meandering, the upper side parts 8b, 8b of the upper support part 8 and the tongue pieces 8c, 8c are installed so as to be shifted in the left and right direction as appropriate with respect to the lower support part 9. It is something that exists.

First, the support C is attached to the trough 2 of the existing corrugated slate roof A.
The support C is placed at a predetermined interval in the width direction of the same roof, and is located almost directly above the structural member 10 such as the main building, and the arcuate support bottoms 8a and 9a of the support C are attached to fixing devices such as 1' lil screws. 11
It is fixed to the structural member 10 at.

Next, the newly installed roof board B is placed between the adjacent supports C1C, and the arcuate bottom part 4 contacts the surface of the valley part 2.

That is, the interval between the adjacent arcuate bottom portions 4.4 across the chevron portion 3 corresponds to the trough portion 2.2 of the corrugated slate roof A.
When the interval is not equal to the distance between the two sides, the chevron portion 3 is shortened or widened in the width direction by the adjacent support C2C, so that the arcuate bottom portion 4 can come into contact with the valley portion 2.

[Effects of the Invention] In the present invention, supports C are installed at predetermined intervals in the troughs 2 of an existing corrugated slate roof where the arc-shaped troughs 2 and the arc-shaped crests l continue alternately. It is fixedly fixed and has an arcuate bottom portion 4 and a chevron portion 3, and the curvature of the arcuate bottom portion 4 is smaller than the curvature of the valley portion 2 of the corrugated slate roof A, and connecting bends are provided at both ends in the width direction. Newly installed roof board B forming part 5.5.

i5 to the trough 2 of the corrugated slate roof A.
! Repair work in which a new roof board B is placed on top of the corrugated slate roof A, and the opposing connecting bends 5, 5 of the adjacent new roof boards B are fixed to form the new roof B. By making it into a roof, firstly, the arcuate bottom part 4 comes into contact with the valley part 2 of the existing corrugated slate roof mA, making it possible to create a strong new roof B, and secondly, it has excellent heat insulation effect. 3. It is advantageous that there is no need to remove the existing corrugated slate roof A.

To explain these effects in detail, first, since the newly installed roof board B1 has the arc-shaped bottom part 4 and the chevron-shaped part 3,
The new roof board B can be expanded and contracted as needed in the width direction, and the width can be adjusted. Also, the curvature of the arcuate bottom 4 of the new roof board B1 of the new building fIB is the same as that of the existing corrugated slate roof. Since the curvature of the valley portion 2 of A is smaller than the curvature of the trough portion 2 of A, even if the arcuate bottom portion 4 shifts in the width direction, the position of the arcuate bottom portion 4 will be the same as that of the existing corrugated slate roof A. The lower surface of the arcuate bottom 4 comes into contact with the valley 2, and the corrugated slate roof A has progressed in deterioration, and the corrugated slate roof A
Even if the corrugated slate roof becomes brittle, the corrugated slate roof A
It has the effect of making it harder to damage and stronger.

That is, the arcuate bottom 4 and chevron portion 3 of the new roof board B are formed, and the curvature of the arcuate bottom 4 of the new roof board B is similar to that of the existing corrugated slate roof. The fact that the curvature of the valley part 2 is smaller than that works synergistically,
Even if the roofing pitch of the valley part 2 of the existing corrugated slate roof A is slightly off, the new roof board B
can be roofed over the entire length of the lower surface of the arcuate bottom 4 of the corrugated slate roof over the troughs 2 of the corrugated slate roof, and not only can the roofing be done in an extremely orderly manner, but it can also be roofed strongly.

As described above, it is possible to easily and quickly construct a new roof B while leaving the existing corrugated slate roof A, which has become extremely brittle, as it is, and to prevent damage to the aging corrugated slate roof A. The greatest effect is achieved where it is done.

In addition, as shown in Figures 6 and 7, the newly installed roof board B
Even if the pinch in the width direction between the arcuate bottom portion 4 and the chevron portion 3 of the roof board B is different, that is, the pitch of the arcuate bottom portion of the new roof board B is smaller than the pitch between the valley portions 2 and the peak portions 1 of the existing corrugated slate roof mA. Even if the pitch between 4 and the chevron 3 is formed small (see Fig. 6)
, the pitch between the arcuate bottom part 4 and the peak part 3 of the new roof board B is smaller than the pitch between the valley part 2 and the peak part 1 of the existing corrugated slate roof A. Even if the pinch is large (see Fig. 7), there is an advantage that the roof can be compressed during roofing, and it can correspond to any pitch of the existing corrugated slate roof A on the lower side.

In addition, by laying the new roof B on top of the corrugated slate roof A, if a void is formed between them, this will act as a heat insulating layer, improving the heat insulation performance and minimizing the occurrence of condensation. Also plays.

Furthermore, in the present invention, since the existing corrugated slate roof Δ is repaired (renovated) as it is, it naturally has the advantage that it can be constructed without impairing the function of the building (factory, company gymnasium, etc.).

Moreover, the new roof B can be selected from various types, and the ability to create a roof image that is completely different from the conventional one has a great effect.
