Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention, when roofing a metal folding plate for repair on an existing roof with corrugated slate, is constructed by a construction method in which the corrugated slate does not meet the construction standard. Therefore, when the waves of the corrugated slate are not roofed at an equal pitch in the direction perpendicular to the flow direction of the water gradient, the intervals between the peaks of the refurbished folding roof material are equal pitches in the direction perpendicular to the flow direction of the water gradient. It is possible to fix the tight frame on the corrugated slate so as to make a good appearance so that the peaks of the refurbished roofing material for refurbishment are evenly pitched. The present invention relates to a tight frame for a renovated folded plate roof material to be implemented.

[0002]

In the field of construction, asbestos slate has long been used as a roofing material because of its excellent fire resistance, water resistance and durability. In particular, a building having a roof covered with corrugated asbestos slate, which has excellent fire resistance, is often used in factories and warehouses in terms of fire protection. Since a considerable number of years have passed since such a building was constructed, as described above, in recent years, a lot of repairs have been required to the roof covered with corrugated asbestos slate.

There are three types of corrugated asbestos slate, large wave slate, medium wave slate and small wave slate, depending on the wave pitch, but most of the roof is a large wave slate (wave pitch: 130 mm, wave height: 39mm, thickness: 6.3mm, 1 sheet:
7 mountains and a half) are used, and this large wave slate (hereinafter,
The corrugated slate) is roofed on the main building material of the building in a state where it is sequentially fixed laterally and upward using hook bolts. The construction standard for forming the roof surface of a building with such a corrugated slate is to fix the ends of the corrugated slate to 1.5 laterally one by one and to fix them sideways, so that the entire roof surface is fixed. Thus, the waves of the corrugated slate have a uniform pitch and form a straight line in the flow direction of the water gradient.

Conventionally, in order to refurbish such a roof with corrugated slate, as shown in FIG. 5, a corrugated portion 1a 'and a corrugated slate 2 which are in contact with the back surface of the corrugated portion 3a of the refurbished folding plate roofing material 3 are shown.
The tight frame 1'in which the upper surface of the valley portion 2a and the valley portion 1b 'which abuts is integrally formed is used. That is,
The work of fastening the ridges 1b 'on both sides of the tight frame 1'to the upper faces of the ridges 2a of the corrugated slate 2 and fixing them to the main material 4 with drill screws is performed sequentially on the side and the upstream side of the roof surface. After that, the back surface of the mountain portion 3a of the refurbished folded plate roof material 3 is brought into contact with the upper surface of the mountain portion 1a 'of the tight frame 1'and the mountain portion 3a of the refurbished folded plate roof material 3 and the tight frame 1 are contacted. The work of fixing the "mountain portion 1a" of the 'with the drill screw was repeatedly performed to the side and the upstream side.

However, since the corrugated slate 2 that is rewound on the roof surface to be repaired is not only a construction error at the time of construction but also clamped on the main material 4 by hook bolts as described above, the corrugated slate 2 is caused by wind. The abutment part with the hook bolt may wear out and shift to the side. As a result, when looking at the roof surface to be repaired, the wave troughs 2a and peaks of the corrugated slate 2 are in the water gradient flow direction. There are quite a few cases where the whole is bent without forming a straight line. Therefore, the lower part is fixed directly to the waveform slate 2,
The conventional tight frame 1'where the refurbished folding plate roofing material 3 is directly fixed to the upper portion is used.
Since the position of the mountain portion 3a of the roof is regulated by the wave condition of the corrugated slate 2, the mountain portion 3a of the refurbished folding plate roofing material 3 is bent as a whole when looking at the roof surface. In addition to the drawback that the design effect is significantly impaired, there is a drawback in that if the degree of lateral displacement is large, the repairing folding plate roof material 3 cannot be fixed to the tight frame 1 '.

[0006] Further, in the process in which the present inventors are studying the repair of the roof surface that is being roofed by the corrugated slate, the roof that is constructed by the corrugated slate does not meet the construction standard, that is, the corrugated roof. The slate has 0s between its ends.
There are quite a few buildings that have roofs (hereinafter referred to as "half-mount piled roofs") that are sequentially fixed laterally on the main building material in a state in which only five piles are stacked (hereinafter referred to as "half-mount piles"). I found that. In such a half-sloped roof, adjacent pitch slate must be close to each other in order to lengthen the width of the half-sloped portion of the corrugated slate. Shorter than (130mm) (usually 115)
Therefore, the pitch of waves is not the same on the entire roof surface. Therefore, if a conventional tight frame is used in which the position of the crests of the refurbished folded-plate roofing material is regulated by the wave condition of the corrugated slate, it is not possible to use the conventional tight frame where the pitch of the corrugated slate waves is offset. The pitch of the tight frame does not match the pitch of the roof part of the folding plate for repair and the pitch of the tight frame, and the pitch of the tight frame as it is fixed to the side. The disadvantage was that the fold plate roof material for repair could not be roofed because the gap could not be tolerated. And further,
This defect was exacerbated by the fact that the width of the half pile of each corrugated slate was not uniform.

Furthermore, the conventional tight frame 1'has a valley 1b '.
Is fixed by contacting with the valley portion 2a of the waveform slate 2, the pitch of the ridge portion 1a 'of the tight frame 1'will inevitably match the pitch of the wave of the waveform slate 2. Since the pitch of the mountain portion of the refurbished folded plate roof material must be an integral multiple of the wave pitch of the corrugated slate 2, the shape of the refurbished folded plate roof material was limited.

[0008]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art, and when corrugating a metal folding plate for repair on an existing roof surface with corrugated slate, Since the existing roof composed of slate is a half-mountain roof, when the waves of the corrugated slate are not evenly pitched in the direction perpendicular to the flow direction of the water gradient, the troughs and peaks of the corrugated slate wave are Even when it is bent as a whole without forming a straight line in the flow direction of the water gradient, or when the pitch of the peaks of the renovated folding plate roof material is not an integral multiple of the wave pitch of the corrugated slate , The ridge of the tight frame, which is fixed by abutting the upper surface of the ridge on the roof of the refurbished folded plate roof material, fixes the ridge of the tight frame linearly in the flow direction of the water gradient and at equal pitches in the flow direction of the water gradient. Fix it with and refurbish the folded plate roofing material for good appearance. Providing a repair folded plate tight frame roofing for carrying out the construction method and the method of repair for folding plate roofing that can be an object.

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned problems, the present inventors have constructed a structure in which a lower part is directly fixed to a corrugated slate and a repair folding plate roof material is directly fixed to an upper part. If you use a tight frame where the peaks and valleys of the corrugated slate are integrally formed, the position of the peaks of the refurbished folded-plate roofing material will be determined corresponding to the troughs of the corrugated slate. Is not straight in the direction of the flow of the water gradient but is bent as a whole, it is affected by this bending and is also affected by the deviation of the pitch of the corrugated slate, and the folding plate roof material for repair Paying attention to the fact that it is not possible to cope with the case where the pitch of the crests is not an integer multiple of the pitch of the wave of the waveform slate, the tight frame is formed by contacting the upper surface of the troughs of the wave slate, and the troughs are formed. The space is horizontal A lower frame formed on the lower frame and a mountain portion to be fixed by abutting against the back surface of the mountain portion of the repaired folding plate roofing material at a pitch matching the pitch of the mountain portion of the repaired folding plate roofing material, and Dividing into an upper frame where the crests are formed on a horizontal surface, forming the lower frame so that both ends are valleys, and arranging so as to straddle the half crests of the corrugated slate In the case of, the part that straddles the half-pile overlap is arranged adjacent to the valley at one end where a long hole is formed in the longitudinal direction, and the wave pitch becomes shorter due to the existence of the half-ply overlap of the corrugated slate. The waveform slate is formed by forming the pitch between the troughs on both sides of the portion that straddles the half-pile overlap portion to be short by a length similar to the length, and overlapping the troughs at the ends of the adjacent lower frames. Arranged to straddle the half-mountain stack For those that are made to contact with the valley of the corrugated slate and fix with screws with a drill screw while absorbing the difference in the width of the half pile of the corrugated slate at the position of the valley where the elongated hole is formed. At the same time, the horizontal surface of the upper frame is brought into contact with the horizontal surface of the lower frame, and the work of screwing with a drill screw at this abutting position makes the position of the mountain portion of the upper frame linear in the flow direction of the water gradient. The present invention has been completed by clarifying that it is possible to make a renovated folded-plate roofing material with a good appearance by sequentially performing the steps laterally and upwardly of the roof.

Hereinafter, the construction method of the refurbished folded-plate roofing material according to the present invention will be described in detail while explaining the tight frame for refurbished folded-plate roofing material according to the present invention with reference to the drawings. FIG. 1 is a front cross-sectional explanatory view showing a state in which one embodiment of a tight frame for a refurbished folded plate roof material according to the present invention is fixed on a half-mounting roof and the refurbished folded plate roof material is roofed by the method of the present invention. 2 is an explanatory view of a sectional view taken along the line AA of FIG. 1, and FIG. 3 is another embodiment of a tight frame for a renovated folding plate roof material according to the present invention, which is fixed on a half-height roof and is folded for renovation by the method of the present invention. Fig. 4 is a cross-sectional explanatory view showing a state in which a plate roofing material is roofed, and Fig. 4 shows that the tight frame for a repaired folding plate roofing material according to the present invention is fixed on a half-mounting roof and the repairing folding board roofing material is roofed by the method of the present invention. It is an enlarged front cross-section explanatory drawing in the center part of the tight frame for refurbishment folding board roof materials in the state where it was.

In order to carry out the method of the present invention, first, at both ends, a valley portion 1aa which abuts the upper surface of the valley portion 2a of the corrugated slate 2 is formed, and the trough portion 2a of the corrugated slate 2 is arranged so as to straddle the half-mounted portion 2b. As for the slate, the part that straddles the half-pile portion 2b is arranged adjacent to the valley 1aa at one end where the long hole 1ac that is long in the longitudinal direction is formed, and the half-pile portion of the corrugated slate 2 is present. Due to this, the pitch between the troughs 1aa on both sides of the portion straddling the half-height overlapping portion 2b is shortened by a length similar to the length at which the wave pitch is shortened, and the troughs 1aa are formed on the horizontal surface 1ab. The lower frame 1 and the mountain portion 1a are formed at a pitch matching the pitch of the mountain portion 3a of the refurbished folding plate roof material 3, and the upper side is formed on the horizontal surface 1bb between the mountain portions 1ba. Reinforced folded plate roof material tight according to the present invention consisting of frame 1b It is to prepare the frame 1.

As the lower frame 1a of the tight frame 1 for a modified folded roof material according to the present invention, a corrugated slate 2 is used.
Since the half-pile part 2b of the ply has a half-pitch part, the pitch of the part is shorter than the wave pitch of the normal waveform slate 2 and the pitch of the wave is not uniform. When the lower frame 1a having a length substantially the same as the width of the corrugated slate 2 is used, the pitch between the troughs 1aa arranged so as to straddle the half-mounting portion 2b of the corrugated slate 2 is The length of the corrugated slate 2 is shortened by a length close to the length at which the pitch of the wave is shortened due to the presence of the half-pile, and is long in the longitudinal direction at the valley 1aa at one end arranged adjacent to the portion straddling the half-ply portion 2b. When the lower frame 1a having the long hole 1ac formed therein and the lower frame 1a having a length shorter than the width of the corrugated slate 2 are used, the half-stacked portion 2b of the corrugated slate 2 is used. Pitch between valleys 1aa arranged across The length of the corrugated slate 2 is shortened by a length close to the length at which the pitch of the wave is shortened due to the presence of the half-pile, and is long in the longitudinal direction at the valley 1aa at one end arranged adjacent to the portion straddling the half-ply portion 2b. It is possible to use a combination of the lower frame 1a having the long holes 1ac formed therein and the lower frame 1a having the valleys 1aa formed at intervals of an integral multiple of the wave pitch of the waveform slate 2.

As described above, in the case where the corrugated slate 2 of the lower frame 1a is arranged so as to straddle the half-hilled portion 2b, the valley at one end is arranged adjacent to the portion that straddles the half-hilled portion 2b. A long hole 1ac that is long in the longitudinal direction is formed in the portion 1aa, but the valley portion 1a at the other end of the lower frame 1a is formed.
In a, a long hole is formed in the longitudinal direction of the lower frame 1a so that a drill screw can be inserted into the purlin 4 through the valley portion 1aa and the corrugated slate 2 of the superposed lower frame 1a.
1ac may be drilled or screw holes may be drilled.

It is also important that any of the lower frames 1a described above is provided with a concave rib 1ad over the entire length of the horizontal surface 1ab formed between the valleys 1aa of the lower frame 1a. This is preferable because the strength of the side frame 1a can be increased. The horizontal frame 1bb formed between the upper frame 1b and the mountain portion 1ba of the tight frame 1 for a refurbished folded roof material also has a concave rib of the lower frame 1a. The upper frame 1 is formed with a concave rib 1bc that is inserted and engaged in the 1ad.
It is preferable because the strength of b can be increased, and when the upper frame 1b is fixed to the lower frame 1a as described later, the upper frame 1b can be easily aligned with the lower frame 1a and the upper frame 1b can be easily aligned. It is preferable because the position of the water gradient with respect to the flow direction is accurately defined.

Then, such a mountain portion of the upper frame 1b
The concave rib 1bc formed on the horizontal surface 1bb formed between the 1ba has a shape such that the head of the drill screw 5 for fixing the upper frame 1b to the lower frame 1a can be housed in the concave rib 1bc. It is preferable to have the drill screw 5 because the head of the drill screw 5 can be prevented from coming into contact with the back surface of the repaired folding plate roof member 3.

[0016]

To carry out the method of the present invention and to roof the refurbished folded-plate roofing material 3 on the existing half-pile roof on which the corrugated slate 2 has been roofed, first, the lower frame 1a and the upper frame as described above are used.
Prepare a tight frame 1 for a refurbished folded roof material consisting of 1b and 1b. Next, the valley 1aa at the end of the adjacent lower frame 1a
The valleys 2a of the waveform slate 2 in a state where they are superimposed on each other.
The lower surface of each valley portion 1aa of the lower frame 1a is brought into contact with the upper side, and at this contact position, the drill screw is inserted into each valley portion 1aa of the lower frame 1a.
And the corrugated slate 2 are passed through the valleys 2a of the corrugated slate 2, respectively, and screwed into and fixed to the main material 4. At this time, if the lower frame 1a has a length that is substantially the same as the width of the waveform slate 2, the overlapping positions of the troughs 1aa of the adjacent lower frames 1a are shifted and the waveform slate 2 is The difference in width between the half-mounting portions 2b is absorbed, and the drill screw penetrates the corrugated slate 2 and is screwed into the main material 4 at the valleys 1aa of the lower frames 1a. Also, the lower frame 1a has a waveform slate 2 respectively.
Has a length shorter than the width of the corrugated slate 2 and the pitch between the valleys 1aa arranged so as to straddle the half-slope portion 2b of the corrugated slate 2 is such that the pitch of the waves becomes shorter due to the existence of the half-slope layer of the corrugated slate 2. A lower frame 1 having a long hole 1ac extending in the longitudinal direction at a valley 1aa at one end arranged adjacent to a portion that is short by a length similar to
a and a valley 1 at an interval that is an integer multiple of the pitch of the wave of the waveform slate 2.
When the combination with the lower frame 1a in which aa is formed is used, the former lower frame 1a is arranged so as to straddle the half-overlapped portion 2b of the corrugated slate 2 and the former lower frame 1a. Valley 1a at the end of and lower frame 1a of the latter
The overlapping position with the valley portion 1aa at the end of the above is shifted, and the drill screw penetrates the corrugated slate 2 and is screwed into the main material 4 at the valley portion 1aa of each lower frame 1a. This work can be easily performed if screw holes are formed in each valley 1aa of the lower frame 1a.

Thus, the lower frame 1a is converted into the waveform slate 2
When fixed to the upper frame 1b, the horizontal surface 1bb of the upper frame 1b is brought into contact with the horizontal surface 1ab of the lower frame 1a, and the two screws 1a and 1b are fixed by the drill screw 5 at this contact position. This is done sequentially to the side of the roof and above so that the position of the mountain portion 1ba becomes linear in the direction of the water gradient flow. At this time, the rib 1ad is formed over the entire length of the horizontal surface 1ab of the lower frame 1a and the upper frame 1a.
When the rib 1bc that is inserted into and engaged with the rib 1ad of the lower frame 1a is formed on the horizontal surface 1bb of b, the upper frame 1b is positioned and regulated in the water gradient flow direction. This can be performed easily and the head of the drill screw 5 for fixing the lower frame 1a and the upper frame 1b can be inserted into the rib 1bc to be hidden.

Thereafter, the back surface of the mountain portion 3a of the repair folding plate roof material 3 is brought into contact with the upper surface of the mountain portion 1ba of the upper frame 1b, and at this contact position, the upper frame 1b and the repair folding plate roof material 3 are contacted. The work of fixing the and is sequentially performed to the side of the roof and to the upper side, so that the construction of the fold plate roof material 3 for repair is completed. At this time, the mountain portion 1ba of the upper frame 1b and the mountain portion 3a of the repaired folded plate roofing material 3 may be fixed by a drill screw screwed from the upper surface of the repaired folded sheet roofing material 3. The sword bolt is fixed to the mountain portion 1ba of the frame 1b, and the mountain portion 3a of the repaired folding plate roof material 3 is struck in the vicinity of this sword bolt portion to the mountain portion 3a of the repaired folded plate roof material 3 If the nut is screwed and fixed after passing the bolt,
Since the work for fixing the refurbished folding plate roof material 3 to the upper frame 1b can be performed only from above, workability is improved.

[0019]

As described in detail above, the method for constructing a folded sheet roof material for repair according to the present invention and the tight frame for a folded sheet roof material for repair according to the present invention for carrying out this method have corrugated slate. If the existing roof is a half-mountain roof that does not meet the construction standards, and if the waves of the corrugated slate are not evenly pitched in the direction perpendicular to the flow direction of the water gradient, the troughs and peaks of the corrugated slate Even if is not a straight line in the flow direction of the water gradient and is bent as a whole, but the pitch of the ridges of the refurbished folding plate roof material is not an integral multiple of the wave pitch of the corrugated slate. However, the mountain part of the tight frame, which is fixed by abutting the upper surface of the mountain part of the refurbished folding plate roof material, is linear in the water gradient flow direction and in the water gradient flow direction, etc. Appearance of refurbished folded plate roofing material fixed at the pitch Than is capable of Ku clothes.

Then, the existing roof with the corrugated slate does not meet the construction standards. Due to the non-uniform width, it is not possible to fix the ridges of the tight frame linearly in the flow direction of the water gradient and at equal pitches in the flow direction of the water gradient, and to roof the renovated folded plate roofing material with good appearance. Was solved at once.

Further, if ribs are formed on the horizontal surfaces of the lower frame and the upper frame, respectively, the strength of the lower frame and the upper frame can be improved, and the work of fixing the upper frame on the lower frame can be performed. Can be performed easily and quickly, the position of the upper frame in the flow direction of the water gradient is surely regulated, and the screw head for fixing the upper frame on the lower frame is inside the rib of the upper frame. Since the folded fold plate roof material for repair and the head of the screw do not come into contact with each other, there is an effect that the fold plate roof material for repair is not easily damaged. In this way, the folding plate for renovation according to the present invention can easily and surely cover the refurbished folding plate roof material on the existing roof in which the corrugated slate has been roofed in the state of the half-story roof that does not meet the construction standard. The method for constructing a roofing material and the tight frame for a modified folded sheet roofing material according to the present invention for carrying out this method have a great industrial value.
