Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a renovation of a corrugated slate roof. More specifically, the present invention relates to a roof-top repair structure in which a new corrugated slate is roofed on a roof renovation without removing the corrugated slate of the existing roof.

[0002]

2. Description of the Related Art In order to renovate an old corrugated slate roof, a method has conventionally been adopted in which an existing corrugated slate is peeled off and a new corrugated slate is then roofed. However, in this method, it is necessary to stop the work under the roof or to move the article under the roof to another place. These measures are irrational from the viewpoint of workability and economy, and in recent years, a method of reforming while performing work under the roof as usual has been proposed. One is a method in which a new waveform slate is directly overlaid on an existing waveform slate roof (Japanese Patent Application Laid-Open No. 62-41855), and the other is disclosed in Japanese Patent Application Laid-Open No. 59-217858. This is the purlin method. In this, as shown in FIGS. 9 and 10, a safety net 90e is put on an existing waveform slate 90a, and a new main house (referred to as an additional main house) 90c is arranged above the main house 90b. This is a structure in which a new waveform slate 90d is laid on the attached purlin 90c and fixed to the purlin 90b with bolts 90f.

Another one is shown in FIGS. 11 and 12.
In the structure disclosed in Japanese Utility Model Publication No. 6-40742, a corrugated foamed polystyrene sheet 1 having the same corrugation as the corrugated slate 101a is placed on an existing roof covered with the corrugated slate 101a.
01b without any gaps, and a repair corrugated sheet 101
This is a structure in which c is roofed and fixed with fixing bolts 101d.

[0004] Compared with the new method of replacing with a corrugated slate, the rebuilding method of roofing is excellent in shortening the construction period and in workability, and is also excellent in reducing the removal cost of the existing roof, and improving the sound insulation and heat insulation by the roofing. Furthermore, by interposing a heat insulating material in the middle of the double roof, the sound insulation and the heat insulation are further improved.

[0005]

However, in the method of directly stacking a new waveform slate, the projecting portion of the existing fixing bolt hits the new waveform slate, so that it must be removed. If not removed, the new waveform slate may be damaged or damaged.

In addition, in the attaching purlin method, a new purlin is provided on the existing corrugated slate, so that the roof thickness is about three times the existing thickness. In addition, since the new purlin is received at each peak of the existing waveform slate, the new purlin must be as strong as the existing purlin, so that the height is high and the weight is heavy. Therefore, problems arise in terms of design and structure.

Further, in a method in which a foamed polystyrene foam corrugated sheet is spread over an existing corrugated slate roof without any gap, and a repair corrugated sheet is fixed thereon, a new corrugated slate is formed with a foamed polystyrene foam corrugated sheet. The fixing bolts may be loosened due to the temporal change of the foamed polystyrene corrugated sheet due to ultraviolet rays, heat, and the like, and the mounting strength of the roof material may be reduced.

[0008] It is an object of the present invention to provide a roofing repair structure which does not increase the thickness of the roof as much as possible, reduces the weight of the purlin, and does not apply the load of a new corrugated slate to the heat insulating material. It is a structure.

[0009]

The inventor studied various construction methods and structures to solve the above-mentioned drawbacks.
The present invention has been made by finding a structure that avoids the influence of the existing fixing bolt protrusions and solves the problem of height and weight due to the mounting purlin and the problem of the temporal change of the heat insulating material.

That is, the same shape as the waveform of the waveform slate, and the cross section perpendicular to the waveform direction has a U-shaped opening downward (hereinafter referred to as a U-shape in cross section) By using the corrugated spacer of (1), the entire surface of the existing corrugated slate in the corrugated direction is received in the entire corrugated direction of the new corrugated slate. Even when a heat insulating material is interposed between the existing waveform slate and the new waveform slate, stable fixing can be performed because the heat insulating material is not fixed through the heat insulating material.

According to the present invention, in order to achieve the above object, the invention according to claim 1 is provided on an existing corrugated slate roof.
In addition, in the roofing repair structure with a corrugated slate, a corrugated spacer with a U-shaped cross section processed according to the corrugation of the corrugated slate is arranged so that the corrugation fits on the corrugated slate of the existing corrugated slate roof, The repairing waveform slate is disposed on the waveform spacer so that the waveforms match, and the repairing waveform slate, the waveform spacer, and the existing waveform slate are fixed to the purlin.

With this configuration, the thickness of the roof is increased only by adding the height dimension of the corrugated spacer and the thickness of the repair corrugated slate. When the heat insulating material sandwiched between the waveform slate and the repair waveform slate is interposed, the heat insulator does not receive the load from the repair waveform slate.

According to a second aspect of the present invention, the corrugated spacer having a U-shaped cross section has an upper surface portion and vertical portions on both sides which hang down from the upper surface portion. A large number of vertical cuts are formed, and the cuts allow waveform deformation of the vertical portion.

By forming the corrugated spacer in this way, the workability and the weight of the corrugated spacer can be reduced.

According to a third aspect of the present invention, the corrugated spacer having a U-shaped cross section is in contact with the curved portions of the peaks and valleys of the waveform of the existing waveform slate at the vertical portions on both sides thereof. A vertical portion corresponding to a straight portion between the two bent portions is cut off.

By forming the corrugated spacer in this manner, the corrugated spacer can be easily mounted on the existing corrugated slate, and the weight of the corrugated spacer can be further reduced.

According to a fourth aspect of the present invention, the corrugated spacer having a U-shaped cross section is formed by a peak portion extending from a vertex to a contact point with a straight portion at a curved portion descending to both sides. A wave-shaped peak-shaped wave spacer is placed over each peak of the wave-shaped slate of the existing wave-shaped slate roof, and a repair-use waveform slate is provided on the wave-shaped spacer. It is characterized in that the partial waveform spacer and the existing waveform slate are fixed to the purlin.

By forming the corrugated spacer in this way, the spacer can be further reduced in weight.

The invention according to claim 5 is characterized in that a heat insulating material is arranged on a side of a corrugated spacer arranged on an existing corrugated slate roof.

With such a configuration, the sound insulation and heat insulation of the roof can be improved.

[0021]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1A is a perspective view showing six ridged corrugated spacers which are omitted in the middle and used in the repairing structure for a shingled roof of the present invention, and FIG. 1B is an enlarged view of the portion (A). It is. The corrugated spacer has a U-shaped cross section, and has an upper surface portion 11a and both vertical portions 11b hanging from the upper surface portion. The waveform of the spacer matches the waveform of the existing waveform slate and the waveform of the repair waveform slate. The width of the upper surface portion 11a is 40 to 80 mm, and positioning of the spacer on the existing fixing bolt makes it easy to position the temporary arrangement of the spacer, and the preferable width for disposing the spacer on the existing purlin is: 60 to 75 mm. The height dimension of the vertical portions 11b on both sides is 20 to 60 mm, and preferably 20 to 30 mm in order to cover the existing fixing bolt with a spacer and limit the thickness of the roof.

The thickness of the corrugated spacer made of iron plate can be appropriately selected in the range of 0.4 to 4.0 mm in accordance with the conditions of the place of use. It is desirable to use a steel plate of 0.6 to 1.2 mm in terms of weight reduction and workability. The durability of the corrugated spacer is improved by performing a color processing such as zinc coating or makeup.

The material of the corrugated spacer may be a metal such as aluminum or an alloy other than iron, or a resin such as a reinforced plastic.

FIG. 2A shows another wave crest spacer 2 having six peaks.
FIG. 1 is a perspective view showing a part 1 with an intermediate omission, and FIG. The width of the upper surface 21a and the height of the vertical portions 21b on both sides are the same as those of the spacer in FIG. In the case of this corrugated spacer, a number of cuts are formed in the vertical portion 21b in a direction substantially perpendicular to the upper surface portion 21a, and these cuts are formed when the spacer is bent from a straight state into a corrugated shape. In 21b, the strips formed by the above-mentioned cuts partially overlap each other at the peaks, and the above-mentioned cuts are opened at the valleys so that the strips spread fan-like with each other. Allows easy bending into a waveform.

FIG. 3 is a partially enlarged view of a corrugated spacer 31 formed by cutting off the abdominal portion 21c (linear portion) of the vertical portion 21b from the corrugated spacer shown in FIG. 2B. By cutting off the abdominal portion 21c (straight line portion), when the waveform spacer is arranged on the existing waveform slate, it easily adapts to the waveform and the mounting of the waveform slate is facilitated, and the weight of the waveform spacer is reduced. I can do it.

FIG. 4 shows still another spacer 41, which is formed by only a peak portion extending from a vertex of a waveform to a contact point with a straight portion in a curved portion descending to both sides. As in the case of FIG. 2, the spacer 41 is also formed with a cut in the vertical portion 41b that hangs down from the upper surface, and bending is facilitated by the action provided by the cut. When repairing a shingled roof, this corrugated mountain spacer with a U-shaped cross section is placed over each of the peaks of the corrugated slate of the existing corrugated slate roof, and the corrugated slate for repair is placed on the corrugated spacer. Then, the repair waveform slate, peak waveform spacer, and existing waveform slate are fixed to the purlin at predetermined locations. This spacer is easy to handle because of its small size and light weight, and is easily adapted to existing waveform slate.

[0028]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In this embodiment, a JI called "large corrugated sheet" is used.
An existing roof that has been roofed with S-standard slate large corrugated sheets has been renovated with the overlapping roof repair structure of the present invention.

A corrugated spacer having a U-shaped cross section was cut into the vertical portions on both sides to form a corrugated slate.

As shown in FIG. 5, the corrugated spacer is provided on both sides vertical portions 51b, 51b of an iron plate main body 51 having a U-shaped cross section.
And a plurality of cuts 51b 'perpendicular to the upper surface 51a.
Is provided, and the length of the vertical portion is 25 mm for the portions 42A and 42B that are in contact with the top and bottom of the existing waveform slate.
And The corrugated spacer 21 shown in FIG.
It is. In addition, part 4 which touches the abdomen of existing waveform slate
The corrugated spacer 31 shown in FIG. 3 is obtained by shaping the iron plate main body 51 having a U-shaped cross section obtained by cutting 2C into a corrugated slate.

As shown in FIG. 6, the corrugated spacer 21 is disposed on the main roof so as to cover an existing fixing bolt (hook bolt-FIG. 8) 63 via a corrugated slate 62 of the existing roof.

At this time, as shown in FIGS. 6 and 7, at the overlapping portions 64 and 65 of the corrugated slate 62 of the existing roof, the height of the corrugated spacer 21 between the overlapping upper direction 64 and the overlapping lower direction 65 is changed. (Vertical part height) is overlapped and the lower end 65 side is raised by about 6 mm.
1 can be arranged horizontally at the same height. In FIG.
Reference numeral 66 denotes a repair waveform slate placed on the waveform spacer 21 disposed at the same height as described above. However, even if the height of the corrugated spacer 21 (the height of the vertical portion) is the same in the entire six ridges, the roof repair can be performed.

Thereafter, as shown in FIG. 8, which is a longitudinal sectional view of a main part of the roof repair structure, a corrugated glass wool heat insulating material having a thickness of 25 mm is provided on the side of the corrugated spacer 21 (corresponding to the area between adjacent existing purlins). 80, a new waveform slate 66 is arranged thereon, and the new waveform slate 66 is fixed to the existing purlin 82 via the existing waveform slate 62, the waveform spacer 21, and the heat insulating material 80 with the fixing bolt 81. Thus, a repaired roof repair structure of the present invention was completed.

In this embodiment, corrugated glass wool is used as the heat insulating material. However, flat glass wool can be provided in accordance with the corrugated slate. In addition to glass wool, rock wool, heat insulating material made of synthetic resin foam, or the like can be used. Can be used. The thickness of the heat insulating material can be appropriately selected according to the height of the corrugated spacer (the height of the vertical portion having a U-shaped cross section). It is advantageous to use a heat insulating material which is preferably the same as or slightly thicker than the corrugated spacer.

[0035]

According to the repair structure of the present invention, it is not necessary to remove the existing roof, so that the repair efficiency can be improved and the cost can be reduced, and the height of the new roof can be changed by the height of the corrugated spacer. By reducing the height of the corrugated spacer, the height of the roof after repair does not change so much that it does not impair the design of the building. As a result, a unique effect is obtained in that it has excellent fire resistance and fire resistance and can be used in semi-fire-resistant buildings.
