JP5177341B2 - Folded plate and its fixing frame and ceiling bracket - Google Patents

Description

  The present invention relates to a so-called folded plate (hereinafter referred to as “folded plate”) made of a steel plate piece bent with a roofing material, a fixing bracket (hereinafter referred to as “frame”), and a ceiling bracket. More specifically, a folded plate that can be fixed by a so-called one-touch method that does not use bolting or bolts and nuts and is only pushed in from above, a frame that is used to fix the folded plate, and a roof that is covered with the folded plate It relates to a ceiling bracket that can be placed and fixed even in places where there are no beams.

  When a plurality of folded plates are used together, so-called peaks and valleys are formed alternately and continuously, and a roof with peaks and valleys of a desired size can be made.

  Conventionally, roofs of large buildings such as factories, warehouses, and gymnasiums are made by joining a plurality of folded plates obtained by bending long steel plates. Many of these are provided with a collar for joining the folded plates and using a braid.

  Also, fixing of folded plates has been mainly performed by fixing bolts and nuts to a tight frame (fixed frame) arranged in advance on the beam.

  For example, a metal folded plate that forms a chevron while superimposing both side surfaces and has a structure that can withstand the load of an operator or a load of snow (see Patent Document 1).

Furthermore, the proposal of the metal folding plate which does not require a support frame only for construction is made (refer patent document 2).
JP 7-11742 A JP 2000-192614 A Patent Documents 1 and 2 are completely different from the configuration and effects of the present invention.

  When rolling a wide roof with a steel plate, it is inevitable that a seam is formed due to restrictions in the production of the steel plate. Therefore, a method is widely used in which a steel plate such as a coil is bent in various ways to form a folded plate, which are joined together.

  Among them, as a folded plate joining means, a folded plate provided with a flange is widely adopted. However, in this method, dust or dust enters the heel after construction, and a so-called straw phenomenon occurs during rainfall, and an accident such as rainwater entering the attic inevitably occurs.

Moreover, in the conventionally proposed folded plate, a method using a bolt is adopted for fixing the folded plate and the frame, and much time is required for the fixing work.
Furthermore, what provided the collar part in the joining of the said folded plate requires the crimping operation | work of a collar part for fixation of a folded plate.

  That is, after the folded plates are combined, the collar portion is temporarily tightened with a temporary tightening machine, and then finally tightened with a final tightening machine (electric seamer). This caulking required a lot of labor and time for the work, and it was difficult to shorten the construction time as a whole.

  In addition, the long folded plate has problems such as a caulking defect due to a molding error during molding and a damage accident of the rust preventive coating film of the folded plate due to the caulking operation.

  Further, the bolt holes penetrating the folded plate and the damage to the coating film cause the rusting of the folded plate at an early stage, resulting in problems such as impairing the durability of the roof.

Moreover, the folded plate of the conventional structure is a system which uses the caulking part of a collar part for the attachment of the ceiling bracket of the ceiling material to the part without a beam.
That is, at the time of caulking work, a method has been widely adopted in which the end of the hanging metal fitting is simultaneously sandwiched between the caulking locations, the hanging metal fitting is held, and the hanging element is suspended. In the above method, one end of the hanging metal fitting is simply clamped at the crimped portion of the collar portion, and it is not firmly fixed.

  Also, with this method, the end of the hanging bracket is pinched at the caulking location when caulking, resulting in a step, and this step becomes an obstacle, causing the locking machine (electric seamer) to fall off and causing the caulking failure. This is a cause of occurrence, and a lot of time and effort, which increases the working time.

  Furthermore, since the above-mentioned fixing method uses a weak holding force (holding state) sandwiched by caulking, the fixing force is originally weak, and a strong load is applied to the folded plate and the suspended ceiling such as an earthquake, typhoon or strong wind. There were not a few accidents such as slipping and dropping off of fixed brackets.

  Accordingly, as a result of intensive research to solve the above-mentioned problems, the inventor can omit the caulking work and the use of bolts and nuts by the following means, and the construction is easy and the ceiling of rainwater The folded plate that can completely prevent the intrusion into the machine and does not require maintenance is completed, and the above problems are solved.

  The folded plate of the present invention is obtained by bending a single long steel plate, and has a structure that does not require caulking work and fixing means such as bolts and nuts for the folded plate for joining, and the folded plate When the seams are joined together, the cut surface of the steel sheet (not rust-proofed) is not exposed on the surface of the roof, so it is possible to completely prevent rainwater from entering and prevent early rusting. I made it.

  That is, the joining of the folded plates is a structure in which the inserted pieces provided on the folded plates to be joined are inserted into the V-shaped receiving grooves provided on the inclined wall surfaces forming the ridges of the folded plates.

  In addition, since the V-shaped receiving groove for joining the folded plates is formed on the inclined wall surface, and the mouth of the V-shaped receiving groove is open to the inclined wall of the mountain portion, the V-shaped receiving groove is temporarily placed in the V-shaped receiving groove during stormy weather. Even if rainwater enters the rainwater, if the rain stops, the rainwater will naturally fall quickly and drain out of the groove because the intrusion groove is inclined. A state does not arise.

  In the joining work of the folded plates, the seam-hanging work, which often damages the rust-preventing coating on the folded plates, which causes early rusting of the folded plates, is made unnecessary.

  The folding plate of the present invention can be bent using a conventional molding machine, and only the molding roller of the molding machine needs to be replaced, and the manufacturing cost of the folded plate is not significantly increased.

  The frame of the folding plate fixing bracket of another invention is a dedicated fixing bracket used for fixing the folded plate of the present invention, and both are used to provide a folded plate having a new structure. I was able to.

  Further, the ceiling bracket for the ceiling material according to another invention utilizes the unique structure of the folded plate according to the present invention, and can be arbitrarily attached even in a place without a beam, etc., and has sufficient strength. This is a high ceiling material hanging bracket.

The folded plates of the present invention are joined together by using the folded plate fixing metal frame according to another invention, and firmly fixing the set folded plates from above without using fastening means such as tightening or bolts / nuts. The so-called one-touch push-in method can be used to fix the folded plate, simplifying the work content and significantly improving workability.

  Since this folded plate is not provided with a saddle, there is no need to apply a seam, and there is no rainwater, dust or dust intrusion into the saddle, so there is no inundation into the attic due to capillarity. Even if it rains for a long period of time, there will be no leakage.

  In addition, if the folded plate of the present invention is used, and when the folded plate is fixed, bolts, nuts, screw nails, etc. are not used for the folded plate itself. And prevent corrosion and prolong the life of the roof.

  Furthermore, since the roof where the folded plates are joined is provided with seams at the side of the mountain, the watertightness is extremely high as a whole, and in the event of a typhoon or heavy rain, there is blowing from the side such as rainwater. However, it can completely prevent rain leakage and there is no worry of water leakage.

  Further, the maintenance work is hardly required, the maintenance cost is low, and it is economical.

  In addition, many parts of the construction work do not require specialized technology and knowledge, and there are few specialists who supervise and supervise the construction, and the construction cost can be reduced by reducing labor costs.

Depending on the working environment, there are cases where the folded board is used from the right side to the left side and from the left side to the right side, but this folded board has an asymmetrical shape. However, since this upper frame is also asymmetrical, using this frame is convenient because the roof can be freely opened from any direction by reversing the position of the upper frame left and right.
In addition, since the frame is separated into an upper frame and a lower frame, the position of the upper frame can be moved left and right even when the folded plates are joined together in a long folded plate. There is an effect that the work of attaching the folded plate to the frame can be smoothly performed without imposing an excessive burden on the folded plate.

  In addition, if the ceiling bracket of the ceiling material according to another invention is used, it is possible to mount the required number of parts where there are no beams, and the ceiling bracket of the ceiling material with sufficient load resistance and high safety. Is obtained.

  Conventionally, roofing of large buildings such as factories, warehouses, and gymnasiums is performed by joining a large number of long folded plates obtained by processing a long metal plate to spread a roof of a predetermined area.

  The folded plate of the present invention is produced in an integrated manner by bending a long steel plate that has been subjected to various rust prevention treatments in advance with a dedicated molding machine.

  Also, in order to prevent damage accidents during the transport of folded plates and save transportation costs, a dedicated molding machine is installed on the ground of the construction site to produce the folded plates continuously and use them immediately. A method can also be adopted.

  In order to further improve the work speed, a dedicated molding machine is pulled up to the height of the roof on the stage adjacent to the construction site, and the folded plate is continuously formed and processed immediately. It is also possible to adopt the method used for

  The steel plate material used in this invention is a so-called color steel plate. For example, a color zinc iron plate, a vinyl chloride steel plate, an aluminized steel plate, a color stainless steel plate, a fluororesin steel plate, a gallium steel plate, a weatherproof Alster steel plate, and other various steel plates that can be bent can be used.

  A steel plate having a thickness of 0.6 mm to 1.00 mm can be used. It can be appropriately selected according to the length between beams to be passed and its application. Preferably, the one with a thickness of 0.6 mm to 0.8 mm is easy to bend and to handle and join the folded plates easily.

  Next, the structure of the folded plate of the present invention will be described.

  The folded plate of the present invention is formed by bending a long sheet of steel as it is with a dedicated molding machine. Therefore, the folded plate is not provided with any parts such as cutting, notching, welding, and excision.

  A lower right inclined wall and a lower left inclined wall are provided with a valley (bottom) of a predetermined width in the longitudinal direction of the steel sheet, and are valley-folded via folding lines at both edges of the valley, and inclined obliquely upward and outward. V-shaped receivers in a state of projecting on the back side of the wall surface, which are mountain-folded through the folds at the upper edge of each inclined wall surface and provided with openings on both wall surfaces. Grooves are connected to each other, mountain folds are made through the fold lines at the upper edge portions of the V-shaped receiving grooves, and the upper right inclined wall and the upper left inclined wall are connected to each other. Have the same inclination angle as that of the lower right inclined wall and the lower left inclined wall, and both inclined walls protrude slightly in the direction of the valley horizontally.

  The left and right upper inclined wall surfaces have the same angle of inclination as the lower inclined wall surfaces, and the entire inclined wall surface horizontally moves in the direction of the valley portion from both lower inclined wall surfaces so as to protrude slightly. This is an indispensable structure for joining the folded plates together.

  A horizontal top is continuously provided in the outer direction through a fold line through a fold line at each upper edge of the upper right slope and the upper left slope wall. The V-shaped receiving groove is provided at a substantially intermediate position between the widths of the left and right inclined wall surfaces.

  Next, a mountain fold is made through the fold lines at the outer edge edges of the two top portions, and the right outer inclined wall surface and the left outer inclined wall surface are connected in a diagonally lower outer direction, and the fold line at the lower edge edge of the right outer inclined wall surface is formed. Through the valley and then folded back to the outside.

  Next, a mountain fold is made through a fold line at the lower edge of the left outer inclined wall surface, an insertion piece is horizontally arranged, and a fold is made by folding back upward through a fold line at the right edge of the insertion piece.

Moreover, the width | variety of the right-and-left top part is formed a little wider than the width | variety of the left top part than the width | variety of a right top part.
This structure is necessary for the operation of joining the folded plates together.

  In order to make it more difficult for the joined folded plates to fall out of the V-shaped receiving groove, the following inserted pieces are removed at the place where the folded plates are joined, that is, where the inserted piece is inserted into the V-shaped receiving groove. Prevention means can also be provided.

  The folded plate is joined in a state where the narrowed portion is expanded and pushed into the narrowed portion near the bottom of the V-shaped receiving groove, so that the insertion piece is inserted at the bottom of the V-shaped receiving groove. Is inserted and fixed near the bottom of the narrow groove of the V-shaped receiving groove with both side walls sandwiched.

  By utilizing the above-described state of the V-shaped receiving groove and the insertion piece, protrusions are provided in the vicinity of the groove bottoms of both V-shaped receiving grooves and at positions corresponding to the insertion piece, respectively. When the inserted piece is inserted into the fixed state, it can be locked to each other.

  That is, on the lower groove side wall near the groove bottom of both the left and right V-shaped receiving grooves, a ridge provided upward in the groove inner direction, and provided downward at a position corresponding to the ridge in the groove near the tip of the insertion piece. Since the protruding ridges are pressed and closely contact each other and engage with each other and the protruding ridges are hooked, the insertion piece is not easily detached from the V-shaped receiving groove.

  The shape of the projecting ridge to be hooked is a convex shape having a semicircular or triangular shape in cross section, but may be any other shape as long as it can be hooked and prevented from falling off.

  Further, in place of the above-mentioned protrusions, protrusions and recesses fitted to the protrusions may be provided at positions corresponding to the protrusions, and the protrusions may be fitted into the recesses to serve as dropout prevention means. it can.

  Next, a frame for fixing the folded plate will be described.

  First, the structure of the frame of the present invention will be described.

  The frame of the present invention is composed of an upper frame and a lower frame, and is used by fixing the folded plate by screwing the upper frame and the lower frame with bolts and nuts.

  This frame is designed and manufactured in advance to a size that can be accommodated inside the crest formed by folded plates. When the folded plates are joined together, the frame abuts the inside of the crest formed by the folded plates. The dimensions are such that they are stored in close contact with the mountain.

  The frame according to the present invention is used for fixing the folded plate according to the present invention. However, it is convenient to use the lower frame by horizontally forming the lower frame so that a predetermined number of peaks and valleys are laterally continuous.

  In this frame, a lower frame is preliminarily processed in a state in which a predetermined number of peaks and valleys are continuously arranged side by side in accordance with the shape of the peaks and valleys formed by the folded plates to be used. Then, they are placed facing each other on the beam passing the folded plate and fixed with screws or the like.

  The folded frame is put on this frame by putting the folded plate on the frame that connects the upper frame to the lower frame fixed to this beam etc., and the folded plate can be joined together, and the folded plate can be fixed, The roof is open.

Using a band-shaped metal plate, flat and horizontal, leaving the central part as a flat part, both sides are bent into a broad mountain shape, and legs are formed, and each leg is horizontally extended to the lower end. Form a fixed foot.
A horizontally long bolt hole is provided on the substantially entire length of the flat portion, and this is used as a lower frame.

  The bent portion of the lower frame may be either square or slightly rounded.

  The bending angle of the lower frame is set to the same angle as that of the lower inclined wall surfaces on the left and right sides of the ridge formed when the folded plates are joined together.

  Next, the upper frame disposed on the flat portion of the lower frame and screwed to the lower frame is a metal plate having the same width as that of the lower frame, and has a substantially U-shaped recessed portion opened outward at the center portion. And a pressing plate having upper pressing pieces on both sides of the recessed portion.

Next, a support column is planted at the center point of the recessed portion of the press plate, and a top plate is horizontally placed at the tip, and is fixed by welding.
Bolt holes for screwing bolts are screwed into the left and right recesses through the support posts at symmetrical positions.

  The size of the top plate is adapted to match the shape of the ceiling inside the mountain portion formed by the folded plate, and is set to a size that makes contact. The top plate whose width is slightly narrower than the left side is fixed to the top of the column in a state of being biased to the top of the column in accordance with the structure inside the mountain.

  The upper frame is composed of a presser plate, a support column, and a biased top plate.

  The structure in which the lower frame and the upper frame are separated and screwed together with bolts and nuts is used when folding the roof using folded plates, depending on the working environment, from the right side to the left side. In some cases, the folded plate has a left-right asymmetric shape, but if this frame is used, any position can be reversed by reversing the position of the upper frame. There is an advantage that the roof can be opened from any direction.

  When the lower frame and the upper frame are connected with bolts and nuts, a substantially tuning fork-shaped gap is formed between the horizontal flat portions on the left and right of the lower frame and the upper presser pieces at both ends of the recessed portion of the presser plate of the upper frame. It is formed. When the folded plates are joined together, the gap is formed in a structure in which left and right V-shaped receiving grooves formed to protrude from the left and right sides are inserted into the gap.

  The overall height of the frame is approximately the same height from the lower end of the lower frame to the top plate of the upper frame, from the valley to the top of the ridge formed by the folded plate, and the inclination angle of the legs of the lower frame is The angle is the same as that of the lower inclined wall surfaces on the left and right sides of the mountain, so that they are in close contact with the back sides of both lower inclined wall surfaces without gaps.

  Next, a method for mounting and fixing the folded plate using the frame of the present invention will be described.

  With this folded plate and this frame, the folded plate itself does not use any fixing means such as bolts, nuts, screws, nails, etc., and it is simple and good quality roofing means by attaching the folded plate to the frame. Can be provided.

A case where the folded plates are joined from the right side to the left side will be described.
Prepare the lower frame that fits the crests and troughs of the folded plate to be used in advance by laterally shaping the specified number of crests and troughs horizontally, and fix them on the opposing beams. And put. The fixing means for the lower frame may be an appropriate method. Further, the upper frame is loosely connected to the lower frame with bolts and nuts. The folded plate is inserted between the fixed frames, and the folded plate is attached and joined together.

  The folded plates according to the present invention can be joined by a simple operation of joining folded plates in order from one direction.

First, the position of the folded plate as the starting point is determined according to the valley and mountain of the lower frame, and first, the upper frame is screwed and fixed in advance at the center position of the bolt hole of the lower frame as the starting point.
Next, all the upper frames located on the left side of the starting point other than the above, that is, downstream, are loosely screwed and connected to the lower frame with bolts and nuts, and the upper frame is installed in the horizontally long shape provided on the lower frame. Place the bolt holes so that they can move freely from side to side. With this configuration, it is possible to finely adjust the fixing position of the folded plates, and it is possible to fix adjacent folded plates to a more appropriate relationship position and prevent unnecessary force from being applied to the folded plates.

Place the narrow top of the two folded plates on the frame, and then place the wide top over the narrow top, Start.
The joining of the folded plates is a joining method that skillfully utilizes the flexibility and elasticity of the folded plates themselves.

Therefore, in order to fix the folded plate of the present invention to the frame, it is not necessary to use any fixing means such as screws, nails or bolts / nuts for fixing the folded plate to the frame. is there.
It can be fixed simply by joining the folded plates and attaching them to the frame, and the roof can be made.

  As a result, there are no bolt holes, screws, nail holes, or the like in the folded plate, so that water leaks from the nail holes or the like and premature rusting from the portions does not occur.

Moreover, since there is no rusting or deterioration from a nail hole etc., the useful life of a roof can be extended.
In addition, the seaming is a structure in which a peak can be formed by pressing the upper folded plate downward with the top of the wider side covering the top of the narrower side. Made it easier.

  Next, with the two folded plates, the folded plate on the upper side with the wider top portion is placed in a state where the folded top portion is stacked on the narrowed top portion, and the upper folded plate is moved downward from above. When pressed down strongly, both folded plates are deformed as a whole, and the inserted piece provided on the upper folded plate is inserted into the V-shaped receiving groove provided on the lower folded plate. Inserted and fitted with snapping, the joining of the two folded plates is completed.

  Both the folded plate placed on the upper side and the folded plate on the lower side are subjected to a force from above and deformed. Even if the inserted piece is inserted into the V-shaped receiving groove, If it returns to the state which does not add, since the folded board is bent, it has the property to return to the original shape before a deformation | transformation immediately.

  Since this folded plate is obtained by bending a thin steel plate having a thickness of 0.6 mm to 1.00 mm into a valley fold and a mountain fold, the folded plate itself has a considerable bend as a whole. Since it has elasticity that can withstand bending deformation, it is a structure that makes it easy to join folded plates by the above-described operation using the bending and deformation described above.

  In addition, all the upper frames located downstream other than the starting frame are loosely connected in a state where the horizontally long bolt holes provided in the lower frame can be freely moved left and right. When the folded plates are joined, the position where the upper frame is fixed is naturally defined by the position of the ridge formed by the folded plates, and the fold that forms the ridge at the defined position is defined. Moves when pushed by the board. Therefore, what has been moved to the correct position is left as it is or if it has not been moved to the correct position, the position may be moved and adjusted, and then screwed and fixed.

  As described above, this frame is separated into an upper frame and a lower frame, and the upper frame is configured to be able to move its fixed position by moving a horizontally long bolt hole in the lower frame. Even when the folded plates are joined, the joining can be performed accurately and smoothly without imposing excessive load (stress) on the folded plates such as excessive bending or pushing.

  In addition, the inside of the ridge is in contact with both lower slope walls of the ridge inwardly to prevent the lateral shaking of the ridge, and the flat part of the lower frame and the presser of the upper frame Since the gap between both sides formed by the pressing piece of the plate is mounted with the V-shaped receiving groove protruding inside the peak portion being inserted into the gap, the folded plate is moved to the left and right of the peak portion. The top plate of the upper frame is in contact with the top of the mountain from the inside of the mountain and supports it from below to prevent the mountain from moving to the left and right. In this configuration, the load bearing strength of the top of the mountain is reinforced.

  As a result, the joined folded plates are firmly fixed to each other by the mounting of the frame, and even if an external force is applied, they are not displaced or moved.

  Each part of the frame that is attached to the inside of the ridge is attached to the inside of the ridge, so that the folded plate attached to the frame is stable and fixed with no rattling. And the fixed state is maintained for a long time.

  In addition, the mounting of the frame in the peak portion is as if a strong skeleton is put inside the hollow peak portion, so that it does not easily generate a dent of the folded plate against an external impact. There is also a function to give impact.

  If you repeat the steps of fixing and attaching the folded plate to the frame, you can make a roof.

  The folded plate of the present invention is formed by bending a single steel plate, the folded plate has no breaks, and does not require bolts, nuts, screws, nails, or the like for fixing, and the folded plates are joined together. Since it is fixed so that water does not enter from the joint between the plates, it is possible to completely prevent rainwater from entering.

  Furthermore, if the folded plate of the present invention is used, two steps of a complicated temporary fastening operation requiring a great amount of labor and time and a final fastening operation by a seamer can be omitted, and the working time and labor can be greatly reduced.

  Furthermore, since the folded plate itself does not require fixing work with bolts, nuts, screws, nails or the like, in addition to the labor saving in the previous period, the working time can be further shortened.

  In addition, since this folded plate has a configuration that can be easily joined, the expertise of roofing work has been significantly reduced, so that fewer specialists are required to direct the work and construction costs can be reduced.

  In addition, the dimensions and proportions of each part of this folded plate (for example, the relationship between peak and valley) are designed and molded in advance according to the requirements of the building to be constructed. It has the advantage that it can be adopted and made of any size and can be obtained with an appearance and aesthetics suitable for the building.

  Next, a ceiling bracket for a ceiling material according to another invention will be described.

  Conventionally, the ceiling material suspension fittings can be arranged at appropriate places by using the beams, and the ceiling material suspension fittings can be arranged by appropriate means.

However, a large building without a pillar in the room inevitably has many places without beams.
However, it is necessary to evenly arrange ceiling brackets from a safety standpoint even in places where there are no beams, etc., and from the cost standpoint, separate construction is required for the placement of suspension brackets. However, it has been a conventional problem to enable the arrangement of the hanging metal fittings by simple means.

  For this purpose, conventionally, a method has been widely adopted in which one end of a hanging metal fitting is sandwiched between the joint surfaces of the ridge portion of the folded plate, and the ceiling member is suspended by caulking the heel portion.

  As described above, this has caused various problems, but the hanging bracket of the present invention solves this problem.

  That is, using the V-shaped receiving groove formed to protrude from the left and right inclined wall surfaces toward the inside of the peak portion of the folded plate of the present invention, the suspension bracket of the present invention is attached and fixed thereto, and the beam or the like Even in places where there is no space, the ceiling brackets can be arbitrarily placed.

  The structure of the ceiling bracket of the present invention will be described below.

  This hanging bracket is made up of a metal plate top plate, bottom plate, long nut (high height), and all screw rods (those that are threaded over the entire length of the metal rod). In addition, the screw rods are assembled and used by screwing all the screw rods.

A rectangular metal plate is used as the lower plate of the flat plate, and female screw holes are formed in both the left and right ends of the lower plate so as to pass through the lower plate upward from the back of the lower plate. . On the lower plate, a metal plate having the same width is formed to form a concave portion that is recessed in a substantially U shape with the central portion opened outward, and an upper plate having both sides of the concave portion as pressing pieces is formed. The upper plate is the same length as the lower plate.
Furthermore, in order to make it easy to attach the hanging bracket, the corners on the surface side on both sides are respectively set so that the tip portions on the opposite surface side of the upper plate and the lower plate are sharp and thin like a single-edged blade. The shape was cut at an angle.

With this configuration, a gap having a predetermined width substantially in the shape of a tuning fork is formed at both ends of the lower plate and the upper plate.
This gap formed by the lower plate and the upper plate pressing piece extends from the entire groove of the V-shaped receiving groove provided on the left and right sides protruding from the inside of the peak, that is, from the groove opening to the groove bottom.

  A frame 30 that is a fixing member for a folded plate used together with the folded plate 1 of the present invention will be described below with reference to FIGS. 1, 2, 3, 5, 6, and 7.

  The frame 30 is composed of a lower frame 38 and an upper frame 43, which are screwed together with bolts 39c, 39d and nuts 37, 37a.

A strip-shaped metal plate having a thickness of 3 mm, a width of 35 mm, and a length of 564 mm is used, leaving a flat central portion having a length of 120 mm to be a flat portion 31, and both sides thereof being bent into a substantially chevron shaped like a divergent leg 32, 33 is formed and the bending angle is 120 degrees with respect to the ground. Fixed legs 34 and 35 extending horizontally outward are formed at both lower ends of the legs 32 and 33, respectively.
Further, the flat portion 31 is provided with a horizontally long bolt hole 36 having a total length of 96 mm into which the bolts 39 c and 39 d are screwed and a hole width of 12 mm.

  The height of the lower frame 38 is 83 mm, and the width from the valley core to the valley core is 500 mm. The angle of inclination of the legs 32 and 33 is the inclination of the peak portion formed by joining the folded plates 1 together. The same inclination angle as the wall surfaces 7 and 10 is set to 120 degrees.

The height of the lower frame 38 is set to 83 mm so as to contact the lower side walls of the V-shaped receiving grooves 11 and 12 provided on the inclined wall surfaces 7 and 10 of the mountain portion.

The upper frame 43 disposed on the flat portion 31 of the lower frame 38 and screwed with the bolts 39c, 39d and nuts 37, 37a will be described.
A metal plate having the same width as that of the lower frame 38 is used to form a substantially U-shaped recessed portion 41 having a central portion opened outward, and a pressing plate 39 having pressing pieces 39a and 39b having a width of 30 mm on both sides. As a result, the pressing pieces 39a and 39b of the pressing plate 39 and the lower flat portion 31 form a substantially tuning-fork-shaped gap that opens up and down on both sides. The gap depth is 30 mm and the gap width is 5 mm.

  The width of both pressing pieces 39a and 39b is 35 mm. The depth of the recessed portion 41 is 5 mm, and the inner dimension of the recessed portion is 35 mm.

  The presser pieces 39a and 39b are positioned on the groove sidewalls on the upper side of the V-shaped receiving grooves 11 and 12 that are bent from the left and right sides in the inner direction of the crest formed by the joined folded plate 1. The V-shaped receiving grooves 11 and 12 are sandwiched from above and below by the holding pieces 39a and 39b and the flat portion 31 of the lower frame 38.

  A support column 40 having a height of 63 mm is planted at the center point of the recessed portion 41, and a top plate 42 having a length of 40 mm and a width of 30 mm is placed horizontally at the tip, and fixed by welding.

  Although the widths of the top portions 13 and 14 forming the peak portions provided on the folded plate 1 of FIG. 1 are asymmetrical on the right side and the left side, the size of the top plate 42 depends on the folded plate 1 for the above reasons. The right side portion 42a of the support column 40 is slightly narrower (17mm) than the left side portion 42b (23mm) and is formed in a biased size so as to conform to the inner shape of the mountain portion to be formed. It is. In addition, bolt holes into which bolts 39c and 39d are screwed are provided in the left and right concave portions of the support column.

  When the folded plate 1 is joined together, the frame 30 is in contact with the inside of the crest formed by the two folded plates 1 so that the entire frame 30 is accommodated so that the frame 30 can be closely attached without any gaps.

The height of 146 mm of the frame 30 is substantially the same height from the lower end of the lower frame 38 to the top plate 42 and from the valley portion 2 to the top portions 13 and 14 inside the peak portion formed by the folded plate 1.
The inclination angles of the legs 32 and 33 of the lower frame are set to 120 degrees so as to be in close contact with the back sides of the lower inclined wall surfaces 5 and 8 at the left and right of the mountain portion, so that they can be mounted without a gap.

  When the upper frame 43 and the lower frame 38 are screwed together with bolts and nuts, the overall dimensions of the frame 30 are 146 mm in height, 500 mm in width, and 35 mm in depth.

Next, a method for joining the folded plates 1 will be described with reference to FIGS. 3, 5, and 6.
In this embodiment, an example is shown in which the roof is run from the right side to the left side.
A lower frame 38 adapted to the crests and troughs of the folded plate 1 to be used is formed in a horizontal manner so that a predetermined number of crests and troughs are laterally continuous. Place each one on top.
The frame 30 that is the starting point for starting rolling is placed by screwing and fixing the upper frame 43 at the center of the bolt hole 36 of the lower frame 38 with bolts 39c, 39d, nuts 37, 37a in advance.
The folded plates 1 are arranged in accordance with the peak portions and the valley portions 2 of the frame 30.

  With the two folded plates, the top 14 of the top of the folded plate on the upper side is arranged in a state of being superimposed on the top 13 of the narrowed top, and the top 14 of the upper folded plate is When pushed down strongly as shown by arrow 20a from above, both folded plates 1 are deformed as a whole, and the inserted piece 22 provided on the folded plate 1 on the upper side is moved downward. It is inserted into the V-shaped receiving groove 11 provided in the folded plate 1 and fits with a snap.

  The frame 30 located on the left side, that is, downstream of the frame 30 at the starting point loosely couples the upper frame 43 to the lower frame 38 with bolts 39c, 39d and nuts 37, 37a, and the upper frame 43 is pushed. In such a state that it can move to the left and right, it is shifted to the left side of the bolt hole 36 provided in the lower frame 38 (FIG. 6).

  The upper frame 43 is loosely connected with bolts 39c, 39d and nuts 37, 37a in a state where the horizontally long bolt hole 36 provided in the lower frame 38 can be freely moved left and right. When the folded plate 1 is joined, the position at which the upper frame 43 should be fixed is naturally defined by the shape and position of the ridge formed by the folded plate 1 at the same time as the joining. It is pushed and moved by the folded plate that forms the ridge to the position.

Therefore, the upper frame 43 that has moved to the correct position is adjusted as it is or the upper frame 43 that has not moved to the correct position is adjusted by moving its position in the direction of the arrow 43a (see FIG. 6). Thereafter, the bolts 39c and 39d and the nuts 37 and 37a may be screwed and fixed.
Thus, the joining of the two folded plates 1 is completed. Repeat this to open the roof.
