Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a fitted-type folded-plate roof. More specifically, the present invention relates to a small-sized folded-plate roof having a configuration in which a working width is widened by relatively lowering a mountain height called a roof deck or an 88 type. The purpose of the roofing material is to provide a fitted-type folded plate roof that is manufactured by improving the roofing material formed by the existing processing machine for folded plate roofing plates.

[0002]

[Prior art]

 Conventionally, as this type of small folded plate roof 1, there is known a structure in which a roof material 2 shown in FIG. The roofing material 2 uses a triple-layered roofing material 2 as shown, and has outwardly downwardly bent portions 5a and 5b formed at upper ends 4a and 4b at both ends, respectively. The upper bases 4c, 4c of the intermediate part are connected to the inclined part 7 having the lower base 6.

The roofing material 2 comprises a plurality of roofing materials 2 laid by using a tight frame 3 having a triple configuration described below, thereby forming a stacked small folded plate roof 1. That is, as shown in FIG. 11, the tight frame 2 in which the sword bolts 9 are respectively implanted in the support portions 8 on the respective top surfaces, the leg pieces 10 are erected on the beams of the building by welding or the like. ing.

Then, the upper bottom 4 a (4 b, 4 c) of the roofing material 2 is brought into contact with the support portion 8 of the tight frame 3 while the roofing material 2 is along the left and right inclined pieces 11, 11,. Then, the sword tip bolt 9 is passed through the bolt hole 12 of the upper bottom 4a (4b, 4c) opened by the sword tip bolt 9, and the upper bottom 4a (4b, 4c) of the roofing material 2 is passed through the support portion 8 of the tight frame 3. After tightly contacting with each other, at least a packing 13 and a waterproof washer 14 are interposed between the threaded portions of the sword-point bolts 9 and the nuts 15 are fastened to form a stacked small folded-plate roof 1 having a plurality of roofing materials 2 laid thereon. Have been.

[0005] The tight frame 3 having the sword-point bolt 9 described above can be used to open a bolt hole 12 through the sword-point bolt 9 in the upper bottom 4a, 4b, 4c of the roofing material 2 to be used. Since the waterproof washer 14 and the nut 15 are required, the number of parts increases, and there are problems such as an increase in installation efficiency and an increase in installation cost.

[0006] Further, the presence of the sword bolt 9 in the support portion 8 may cause an unexpected accident during construction. In addition, if the bolt hole 9 is not opened at the center of each of the upper bottoms 4a, 4b, 4c of the roofing material 2 with the sword bolt 9 at the time of construction, the sword bolt 9 is forcibly passed through the bolt hole 12 so that the bolt hole 12 is formed. Some of them are large and become the main cause of rain leakage, and the roof surface that is constructed is distorted or bent, which is not desirable for aesthetics.

[0007]

[Problems to be solved by the invention]

 Recently, in order to solve the problems of the foldable small folded-plate roof having the above-mentioned configuration, mountain-shaped ribs are formed on the tops of the roof material, and locking steps are formed on both shoulders of these ribs. Therefore, a so-called boltless fitting type mounting structure for a folded plate roof has been developed in which a fixed bolt such as a sword bolt is not provided on the folded plate (see Japanese Utility Model Application Laid-Open No. 60-1333025).

[0008] However, when the locking step is locked to the elastic locking pieces of both shoulders of the lock frame, the top of the rib has a flat shape. Therefore, the top of the rib and the top of the lock frame are in a tight contact state with no gap, and the rainwater causes a capillary phenomenon, which poses a serious problem as a roof.

In addition, the above-mentioned locking piece is provided at the upper end of the inclined shoulders by cutting the three sides of the left and right and the lower end while leaving the upper end, and is provided in an inclined manner, and has a configuration having elasticity. However, if an external force is applied to the locking piece when the locking step of the rib is locked to the locking piece, or if the roof receives wind pressure or the like, it becomes difficult to maintain an appropriate inclined shape of the locking piece. However, there is a fatal problem as a roof because the locking step is disengaged from the locking piece due to the bending of the locking piece or the displacement of the shoulder, and the folded plate comes off the lock frame. .

[0010] The above-mentioned roofing material 2 is generally formed into a triple structure by using a material such as a 914 mm wide zinc iron plate, but is partially formed into a 610 mm width or 762 mm width. Is also employed. It is said that the stacked small folded roof 1 has a relatively low mountain height while maintaining a certain level of strength, thereby widening its working width, and pursuing economic efficiency. Its applications range from factories, warehouses, offices to general homes, apartments, garages, etc. Among the stacked folded roofs, this small folded roof 1 is the most widely used construction method. The machine is the most popular model nationwide.

For many years, the applicant of the present application has been engaged in the development, manufacture and sale of metal folded-plate roof parts, and in view of the spread of the forming machine for the lap-type small folded-plate roof, the applicant has been considering the existing technology. As a result of repeated research and development of a new type of small-sized folded-plate roof with a new configuration, the above-mentioned problems have been solved. The purpose is to provide.

[0012]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention relates to a method of forming a roof material processed by an existing forming machine for a small folded-type roof with an upper bottom portion at one end of the roof material using a special forming machine. To the bottom portion connected to the flat portion, the other end to the top bottom portion on the other end side of the roofing material, and the middle to the top bottom portion in the middle of the roofing material to the top portion on the other end side. The gist is that it is composed of a folded-plate roof molded in the same manner as that described above.

[0013]

[Action]

 According to the present invention, when the upper and lower portions formed by the curved portion and the constricted portion are fitted by pressing down from above the locking portion of the tight frame, the left and right constricted portions are opened, and the tight portion is opened. The top part and the top part of the roof plate can be easily fitted to the locking part of the frame, and the fitting state is strengthened by the constricted part, so that the detachment can be prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described. FIG. 1 is a perspective view showing a folded shingle of the first embodiment of the present invention, FIG. 2 is a schematic explanatory view showing an example of forming the shingle, and FIG. FIG. 4 is a front view showing a folded roof with the same roof plate, FIG. 5 is a perspective view showing a folded roof of the second example, and FIG. 6 is a folded roof of the third example. FIG. 7 is a perspective view showing a main part of a different tight frame, FIG. 8 is a front view showing a folded-plate roof using the same roof plate, and FIG. 9 is an example of using a special forming machine. FIG.

A folded sheet shingle 20 of the first example shown in FIGS. 1 and 2 is obtained by modifying a roof material 2 constituting a conventional lap-type small folded sheet roof 1 and forming the sheet as shown in FIG. To give a new configuration. That is, the portion of the upper bottom 4a having the bent portion 5a on one end side of the roofing material 2 has an upward flat portion 21 having a loose outer end portion and a "-"-shaped portion formed on the inner end portion of the flat portion 21. A curved portion 22 and a recess 24 formed by a constricted portion 23 formed by bending the upper end side of the inclined portion 7 of the roofing material 2 are formed. A bent portion 25 is formed on the upper end side of the inclined portion 7 of the roof material 2 following the constricted portion 23.

On the other hand, the portion of the upper bottom 4b having the bent portion 5b on the other end side of the roofing material 2 is a loose upwardly arcuate portion connected to the right and left “C” -shaped curved portions 30 in the same manner as described above. 31 and the upper end side of the inclined portion 7 of the roofing material 2 are formed as a top portion 33 composed of a constricted portion 32 connected to the curved portion 30. The middle upper bottoms 4c, 4c of the roofing material 2 are formed into the lugs 36, 36 having the same structure as the lug 33.

In the figure, 26 is a folded portion provided at the outer end of the flat portion 21, and 27 is a hollow drain portion provided in the flat portion 21. A backing material 28 made of an inorganic fiber sheet or the like is stuck on the back surface of the roofing material 20 as shown by a one-dot chain line in FIG. 1 to provide heat insulation, fire resistance, dew-proofing, sound absorption and the like. Although the performance is ensured, the backing material 28 may be either before or after forming, and the folded shingle 20 is desirably formed in a triple configuration as described above. However, the present invention is not limited to this. Reference numeral 29 denotes a lower bottom, and reference numeral 34 denotes an extension part of the upper part 33.

The folded shingle 20 having such a configuration is newly provided with a lower thickness than the roof material 2 formed by the existing forming machine for lap-type small folded shingles, which is widely used as described above. The structure of the conventional roofing material 2 is improved by adding the components such as the ribs 24, the ribs 33, and the ribs 36. In other words, the conventional roofing material 2 is formed by an existing lapping type small folding board roof forming machine, and the new lower part 24, the upper part 33, and the lower part 36 are formed by the existing lapping type. By using a new forming machine that is different from a small folding roof forming machine, the existing forming machine can be used effectively, and a new folded sheet shingle can be purchased only at the cost of purchasing a new forming machine. 20 takes into account the economics of molding.

Next, a description will be given of a step of forming the folded roof panel 20 shown in FIG. First, the upper bottom 4a is bent in a plurality of times and the bent portion 5a is bent substantially in a hanging manner to form a hanging portion 500. The hanging portion 500 is sequentially turned over, and the upper end 4a becomes an upward flat portion 21 having a loose outer end. A plurality of forming processes are performed as described above to form a flat portion 21 having a concave draining portion 27 having a folded portion 26 at the outer end.

The bent portion 5b of the upper bottom 4b is bent at its outer end to form a beveled portion 501 having a gentle angle, which is subjected to a plurality of bending processes to obtain a curved portion 30, a constricted portion 32, and an extended portion. The protrusion 33 is formed. At the same time, in the portion in contact with the upper bases 4a, 4b and the inclined portion 7, the curved processing to be the curved processing surface 502 is repeated a plurality of times, and the bent portion formed of the curved portion 22 and the constricted portion 23 connected to the flat portion 21 is formed. 24, a loose upward arcuate portion 31 connected to the left and right curved portions 30, and an upper portion 33 formed by a constricted portion 32 are formed.

On the other hand, a portion in contact with the upper bases 4 c, 4 c and the inclined portion 7 includes an upwardly curved portion 31 continuous with the left and right curved portions 30 by repeatedly performing a curved process as the curved surface 503, and a constricted portion. Each of the portions 36 formed with the portion 32 is formed. In addition, these forming processes are performed through a plurality of processing steps using a forming roll or a piece member (not shown). The inclined portion 7 has a first bent portion 25 formed therein.

FIG. 3 shows a tight frame 40 used for the folded shingle 20. In the tight frame 40, support portions 44 having locking portions 43 are formed at both ends of the top surfaces of inclined pieces 42, 42 provided with left and right “U” -shaped bulging portions 41 for reinforcement. In addition, as shown in the figure, the supporting portion 44 has a rigid structure by providing reinforcing slopes 45 on the front and rear side edges. In the figure, 46 is a fixing hole at the time of molding, and 47 is a leg piece.

FIG. 4 shows an example in which the tight frame 40 is used. That is, each leg piece 47 is fixed to the beam 48 of the building by welding or the like and erected as in the past, and the inclined portions 37, 37,. The upper and lower ribs 24, 33, 36 of the folding board roof plate 20 are engaged with the locking parts 43, 43 of the support part 44 of each tight frame 40, respectively. Next, the upper part 33 is fitted to the lower part 24a of the adjacent folded plate roof plate 20a, and the folded plate roof plates 20, 20a,... Are successively laid to form a fitting type folded plate roof. ing.

FIG. 5 shows a folded shingle roof plate 50 of the second example, which is flat instead of the loosely upwardly curved arc portion 31 connected to the “U” -shaped bent portion 30 of the top portion 33 and the top portion 36. The other features are the same as those of the first example.

The folded roof panel 55 of the third example shown in FIG. 6 is different from the first example in that a second bent portion 56 is formed in the center of each inclined portion 37, and the other configurations are the first example. In combination with the bent portion 25, the bent roof plate 55 is prevented from warping. In these second and third examples, though not shown, a backing material may be attached.

The tight frame 40 described above can be used for the folded roof panel 55 of the third example, but the tight frame 58 of FIG. 7 may be used. It goes without saying that the title frame 58 may be used.

The tight frame 58 has upper and lower supporting pieces 60 formed on the upper ends of the left and right inclined pieces 42, 42 through vertical standing parts 59, 59, as viewed from the side. Draw-formed portions 61, 61,... Formed by drawing at the four corners of the support portion 60 are formed, and from the upper ends of the upright portions 59, 59, the upper ends of the inclined pieces 42, 42 are formed. Then, locking pieces 62, 62 having three sides cut at the left, right, and lower ends are provided. The locking piece 62 has a curved portion 63 on the base end side and a bent portion 64 on the distal end side as shown in the figure, and is integrally formed so as to protrude from the support portion 60. In the figure, reference numeral 65 denotes a window hole for forming the locking piece 62.

FIG. 8 shows a fitting-type folded plate roof of the third example of the folded-plate roof plate 55 and the tight frame 58, and the fitting-type folded plate of the first example shown in FIG. The description is omitted because it is substantially the same as the roof.

FIG. 9 shows an example of use of a forming machine 70 capable of forming and processing the above-mentioned folded shingles 20, 50 and 55 exclusively. In other words, in FIG. 9A, a forming machine 70 capable of exclusively forming and forming the fitting-type folded plate roof plates 20, 50, and 55 is added to the existing forming machine 71 for the small-sized folded plate roof. This is an example of forming a new folded roof shingle 20, 50, 55 in a connected state, which is the most ideal type of the present invention.

FIG. 9 (2) shows a fitting type folded plate roof plate 20, 50 by using a forming machine 70 capable of exclusively forming the small stacked folded plate roof 1 formed separately or at another place. 9 and FIG. 55 are shown. FIG. 9 (3) shows a state in which a fitting-type folded plate roof plate 20, 50, 55 is formed by a forming machine 70 capable of forming and processing the forming material 72 exclusively for this purpose. Respectively, and its application can be used in a wide range, and the existing molding machine 71 can be effectively used.

[Effect of the invention]

 According to the present invention, after forming the conventional lapping type roofing material by the conventional lapping type small folding roof forming machine, the mating type is newly provided by a new forming machine. A folded shingle can be formed. Therefore, the cost is much lower than the cost of manufacturing a new series of molding machines, and the conventional molding machines are not wasted and are economical.

Further, according to the present invention, since the upper, lower, and lower portions of the folded shingle are provided with a constricted portion connected to the bent portion, the strength is significantly improved and the strength is increased. In addition, the engagement with the tight frame and the fitted state of the folded shingles are firm, and the detachment thereof can be prevented.

Further, in the folded shingle, a gap is formed in the engagement portion of the tight frame with the support portion due to the arc portion of the engagement portion, so that a capillary phenomenon such as rainwater can be prevented.

In particular, according to the present invention, since one end is formed in a flat portion having a folded portion, the strength of the flat portion is increased, and the width of the flat portion in the flat portion is widened or narrowed. The tolerance of the board width can be absorbed, and the curving and bending of the lower part can be reduced with respect to the upper part to be fitted. Further, since the top portion is fitted to the upward flat portion, the fitting is tight and the fitting portion of the tight frame is firmly fitted.
