DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof repair method for installing and repairing a new metal sheet roof material without tearing down an old roof material of a factory or the like and removing it. is there.

[0002]

2. Description of the Related Art When roof materials of large factories, warehouses, gymnasiums, etc. become obsolete, if they are removed and new roof materials are installed, it will not be possible to operate the factories or use warehouses during the construction period. Becomes Therefore, a new metal roofing material is stacked on the existing roofing material without removing it (for example, Japanese Utility Model Publication No. 63-46576).

[0003] Fig. 3 shows a typical example. A metal fitting 6 having a hat-shaped cross section is arranged so as to straddle a mountain portion 10 of an existing tile bar roofing material 1 in a factory or the like, and a drill tapping screw is attached to a leg end thereof. At 81, a screw is fixed to the purlin 3 via a base material 4 made of a wooden board or the like, and an end on one side of the new metal sheet roof material 2 adjacent to the top surface of the metal fitting 6 is drilled and tapped. A method of fixing with a screw 82, overlapping the end on the other side with the screw 82 and fixing with a means such as caulking is adopted.

As described above, according to the conventional construction method, drilling is performed on a base material and a main building when a new metal plate roof is installed, so that construction waste, dust, dust, and the like fall inside the building. Therefore, extensive curing is required, such as setting up tents at operating factories, warehouses in use, and gymnasiums to prevent falling objects. Also, depending on the building, the location of the main building may be irregular, so that the metal fittings cannot be mounted at a desired location.

Therefore, the present invention provides a new metal sheet roofing material,
The task was to provide a roof repair method that can be installed on existing tile rod roofing material with good workability and good installation stability without generating construction waste, dust, dust, etc. is there.

[0006]

The roof repair method according to the present invention is characterized by using a clamp fitting which advantageously utilizes the shape of the crest of a roofing material for a roof tile having substantially vertical sides on both sides. And a clamp having a U-shaped cross section and a frame in which the leg ends of the opposing side walls are bent inward, and a screw member that penetrates and tightens the side walls to push the side walls toward each other. . And this clamp metal is arranged so that it may straddle the mountain part of the existing roofing material of a tile rod, a screw member is tightened, the mountain part is pinched from both sides by both leg ends, and the clamp metal is fixed. The ridges of the newly-installed metal sheet roof material are superimposed on a large number of clamps fixed in this way, and these are screwed and fixed to the clamps (claim 1). Therefore, existing roofing materials,
There is no need to process the base material, the purlin, etc., and a new metal sheet roof material can be easily installed without generating waste, dust, dust and the like.

[0007] As the clamp, the cross section is substantially inverted U
A frame having a stepped portion formed in the middle portion of the side walls opposed to each other in a U-shape, a bolt penetrating the upper part of both side walls, and a clamp fitting composed of a nut tightened into a screw point of the bolt can be suitably used. ). This clamp fitting can be easily positioned on the crest by engaging the step with the top surface both ends of the crest of the tile rod roofing material. It can be fixed to the peak.

[0008]

FIG. 1 is a view showing a main part of a roof repaired according to the present invention, and FIG. 2 is a view showing a clamp fitting used for carrying out the present invention. As shown in FIG. 1, the existing roofing material 1 made of metal is made of a metal plate.
The roof bar 3 is installed in the main purlin 3, and has a tile bar 10 orthogonal to the main purlin 3 at a predetermined interval.

[0009] In the tile rod portion 10, the opposite end of the adjacent roofing material 1 is bent in the vertical direction, and the bottom wall of a U-shaped cross section 12 disposed between the vertical walls 11 on both sides holds the wooden bristle board 4. It is fastened to the purlin 3 by a drill tapping screw 83 penetrated. Then, both ends of the shallow U-shaped cap 13 arranged on the upper part of the hanging member 12, the upper end of the side wall of the hanging member 12, and the upper end of the vertical wall 11 of the roofing material 1 are overlapped and folded and joined. It is.

A clamp member 5 is fixed to the tile rod portion 10 so as to be gripped. As shown in FIG. 2, the clamp 5 includes a frame 51 formed of a steel plate having a thickness of about 2.0 mm to 2.5 mm, a bolt 52, and a nut 53. The upper portion of the frame 51 has an inverted U-shaped cross section in which the opening side is slightly widened, and the left and right side walls 51 facing each other are bent outward and further spread downward in a C-shape via a stepped portion 513 that is bent further downward. It is bent inward like a hook. Holes 514 for allowing the bolts 52 to pass therethrough are provided in the upper portions of the side walls 51 at corresponding positions. The interval between the left and right step portions 513 is an interval corresponding to the interval between the left and right protruding edges 14 of the tile bar portion 10 of the existing tile bar roof 1, and the interval between the left and right leg ends 512 is Left and right vertical walls 11 of the tile bar 10
It is larger than the interval between them.

When installing a new metal sheet roofing material 2, first, clamp metal fittings 5 are arranged on a tile rod portion 10 of an existing tile rod roofing material 1 so as to straddle the same. The clamp fitting 5 is positioned by engaging the left and right steps 513 with the left and right protruding edges 14 of the tile bar 10. When the nut 53 is tightened into the threaded end of the bolt 52 penetrated by the hole 514 between the left and right side walls 511 of the clamp 5, the side walls 511 are pushed in a direction approaching each other, and the left and right leg ends 512 integrated with this. By clamping the vertical wall 11 of the tile bar 10 from both sides, the clamp metal 5 is firmly locked to the tile rod 10 as shown in FIG.

On the other hand, the newly-installed metal sheet roofing material 2 is composed of a number of long roofing materials that cover the space between the respective tile rod portions 10 of the existing roofing material 1 and has a heat insulating material 7 attached to the back surface. The opposite end of each adjacent roofing material 2 rises obliquely, the upper end on the upper side has a saucer shape, and the upper end on the other side is shaped to cover it. To install each roofing material 2, the upper end of the tray-shaped end on one side is drilled with a tapping screw 8 from above.
4 is screwed in and fixed to the clamp 5. 840 is a washer. Then, the upper end of the other end is overlaid on the upper end of one end fixed with the drill tapping screw 84,
The edge is fixed by caulking to the locking projection 23 on one side.
As a result, the ridges 2 formed at the ends of the roofing material 2 on both sides
1 covers the existing tile rod portion 10 and the clamp fitting 5.

[0013]

According to the roof repair method of the present invention, the existing roof material, base material, purlin, etc. are not processed, and therefore, the construction is carried out in the state of use of the building without dropping debris, dirt and dust in the building. can do. In addition, since the clamp fitting clamps and fixes the tile bar portion of the existing roof material, the workability can be easily and stably attached. The present invention,
The present invention is not limited to the above-described structure of the tile rod portion, but can be widely applied as long as both side surfaces have a vertical wall shape capable of sandwiching the same from both sides. In addition, the structure of the ridge of the newly-installed metal sheet roofing material is not limited to the above structure, and other structures, for example, the upper end flat portion of the rising end of the adjacent roofing material are overlapped, and the top surface of the clamp is screwed. An appropriate structure such as fastening together with members can be taken.
