Description

  This invention is a roofing construction method for a metal fitting type folded plate roofing material, and in particular, it is possible to easily and quickly connect the ends of adjacent roofing materials by a goose joint, and roofing construction can be performed. Further, the present invention relates to a roofing method for a fitting type folded plate roofing material having an excellent appearance and excellent strength against windstorms at a seam fastening joint.

  As a method of roofing to factories, warehouses, stores, etc., one side edge in the width direction is conventionally connected via a roof bracket (tight frame) fixed at a certain interval on the roof base (beam). One metal folded plate roofing material provided with an inner goby side fitting part formed in the part, and an outer gore side fitting part (upper goby) formed on the other side edge in the width direction of the roofing material ) Is connected to other adjacent roofing materials, and the metal folded plate roofing materials are sequentially connected to each other, and the construction method of lifting the roof in a boltless state (fitting type) is known. (Patent Documents 1 and 2).

  As such a conventional fitting type folded plate roof material, the shape of the inner / outer goby side fitting part is an inverted L-shaped square goby (Patent Document 1), an approximately arc-shaped round goby (Patent Document 2). ), And some of which are substantially triangular goby.

  However, in the roof plate of Patent Document 1, when upward pressure is generated by blowing wind on the main plate portion, at least one of the inner goby side fitting portion (reverse L shape) and the outer gouge side fitting portion is used. When the rotational moment due to wind pressure or other factors is applied, the gouge joint is easily disengaged, or when the worker walks on the roof and generates downward pressure, There was a problem of loosening and coming off.

  Moreover, in the folded-plate type roof board of patent document 2, the structure of the inner / outer goby side fitting part which is a junction part of roof materials consists of a fitting structure of a circular cross section, and after fitting, it is negative by wind blowing up. Although it has a stable strength against pressure and pressure caused by the operator's stepping, it cannot be said that the gouge fastening processability is good, and the bending position of the top part of the outer goat side fitting part becomes uneven during the gouge fastening process. The problem to be solved remained that it was easy, the tightening force was weak, and straightness was easily lost.

  When the bending position of the outer goby is not constant (for example, as shown in FIG. 11, when the core of the outer goby is closer to the right side (FIG. 11 (a)) or the left side (FIG. 11 (b)) than the center. ), The strength of the goby is reduced.

  In addition, when the inner / outer goby side fitting part is made of a triangular goby, it is easy to fasten and tightly fit, and after fitting has a stable strength against wind pressure, Since the fold (folded line) at the top of the side fitting portion is sharp, it is difficult to cope with the distortion of the existing roof foundation and tight frame, and there is a problem that the straightness of the appearance and the shape accuracy are poor.

  In addition, the metal plate has a tolerance (0 to +7 mm) in the width of the original plate, and the error is absorbed by the inner gouge side fitting portion and the outer gouge side fitting portion formed on both side edges of the metal plate. Therefore, the shape of the fitting portion changes for each metal plate, and the inner goby side fitting portion and the outer gouge side fitting portion may not be completely fitted.

  In addition, in construction work of such a fitting type roofing material, it is difficult to determine whether the gouge tightening fit state is good or bad from the outside at the time of construction. It is extremely important to determine the shape of the.

Hereinafter, the present invention will be described with reference to typical embodiments.
The fitting type folded-plate roof material used for the roofing construction method of the present invention shown in FIG. 1 is a rectangular metal plate bent into a waveform in the width direction, and is formed at the center in the width direction. Inclined side plate portions 2, 2 ′ that are folded up and raised from both side ends in the width direction to the portion 1, and are further provided from the upper ends of the inclined side plate portions 2, 2 ′. The horizontal portions 3 and 3 'projecting in the horizontal direction are connected in series, and the free end portions of the horizontal portions 3 and 3' are provided on the outer goby side fitting portion 4 and the inner goze side, which will be described in detail later. Each of the fitting portions 5 is bent.

  The roofing material used in the present invention is fitted to the inner goby side fitting portion 5 of one roof plate by covering the outer gobe side fitting portion 4 of the other roof plate from above via a metal fitting described later. The roofing can be done by a boltless construction method in which the adjacent roofing materials are joined together in the width direction. In addition, description of the shape and structure of a roof board is mainly described based on the cross-sectional shape of this roofing material.

  The characteristic structure of the roof material used in the present invention is the cross-sectional shape of the outer goby side fitting portion 4 and the inner gobe side fitting portion 5 and the fitting structure at the time of the gouge fastening. First, the outer goby side fitting portion 4 will be described. As shown in FIG. 2, the outer goby side fitting portion 4 is located at the free end portion of the horizontal portion 3 protruding from the inclined side plate portion 2 of the roof, and the state before the goze tightening process rises substantially vertically. A right leg 4a as a base side leg, a dome-shaped head 4b connected to the upper end of the right leg 4a, and an extension of the head 4b on the inner goat side fitting after the gouge fastening A left leg portion 4c as a side end portion side leg portion extending along the leg portion 5a of the joint portion 5 is provided in a row, and the cross-sectional shape has a substantially bowl shape, The entire side fitting portion 5 is covered. Here, in the dome-shaped head 4b, a portion having a different curvature (small curvature radius) from the other, which should be a starting point of bending at the top, is another portion (large curvature radius) on both sides in the width direction. Are formed so as to be smoothly connected.

  On the other hand, as shown in FIG. 2, the inner goby-side fitting portion 5 is located at the position of the free end of the horizontal portion 3 ′ protruding from the inclined side plate portion 2 ′ and rises substantially vertically. And a mountain-shaped head portion 5b formed continuously with the upper end portion of the leg portion 5a, and the entire cross-sectional shape has a substantially umbrella shape.

  According to the roofing construction method of the present invention, as shown in FIG. 2, the outer leg side fitting portion 4 is placed on the inner goby side fitting portion 5, and then the left leg of the outer goby side fitting portion 4 is covered. The portion 4c is deformed by being pushed down from the position indicated by the dotted line to the position indicated by the solid line along the leg portion 5a of the inner goby side fitting portion 5 located on the inner side. By tightening the leg part 5a and the horizontal part 3 'of the joint part 5, the gouge fastening process can be performed firmly.

  That is, according to the present invention, the negative pressure due to wind blowing or the like is applied to the left or right of the roof plate in the direction indicated by the arrow in FIG. The left and right overhanging parts 4e and 4e 'at the lower end of the dome-shaped head 4b of the outer goat side fitting part 4 and the left and right of the lower part of the mountain-shaped head 5b of the inner goat side fitting part 5 The overhanging portions 5d and 5d ′ collide with each other, and the rotation of the roof plate is restricted, so that the fitting can be prevented from loosening or coming off.

  The inner goat side fitting portion 5 is formed with a folded overlap portion 5c that is folded and overlapped with the lower surface of the non-leg portion side, that is, the free end portion side. Thereby, the chevron head 5b can be reinforced, the deformation at the time of the gouge tightening process is suppressed, the accuracy of the shape is improved, and the tolerance (error) of the original plate width is absorbed by the folded overlap portion 5c. Therefore, the inner goby side fitting part 5 can always be maintained in the same shape, and the inner gobe side fitting part 5 and the outer goby side fitting part 4 can be firmly fitted. . The folded overlap portion 5c may be folded back to the upper surface side of the inner goat side fitting portion 5 in addition to being folded back to the lower surface side of the inner goby side fitting portion 5 as shown in FIG.

  Further, it is preferable that the horizontal portions 3 and 3 ′ are inclined slightly downward toward the base portion 1 side. Thereby, it can prevent that water permeates into the goat fastening joint part of the inner goby side fitting part 5 and the outer gore side fitting part 4.

Thereby, the board width required as the outer goby side fitting part 4 and the inner goat side fitting part 5 can be reduced as compared with the roofing material of FIG. 2 formed so that the legs rise substantially vertically, Accordingly, the height from the base portion 1 of the roof material to the top of the fitting portions 4 and 5 can be increased, so that the rigidity and strength of the entire roof material against bending can be improved.

  Further, the dome-shaped head portion 4b of the outer goat side fitting portion 4 is a fold-shaped portion that has a different curvature (small radius of curvature) from the other portion, that is, a ridge portion that should be the starting point of bending at the top. The line 4d is clearly formed. By providing this fold line 4d, the outer goat side fitting portion 4 is more clearly identified at the start of bending at the time of the gouge tightening process, and can be easily molded, and at the same time, there is no variation in the ridge line (ridge), Moreover, even if the roof base (beam material) and tight frame are not uniform and some positional deviation occurs, the deviation of the core can be blurred, and the appearance of the roofing can be finished beautifully.

  As in the case of FIG. 2, the outer gouge side fitting portion 4 and the inner gouge side fitting portion 5 are covered with the outer gouge side fitting portion 4 on the inner goze side fitting portion 5, The left leg portion 4c ′ of the goby side fitting portion 4 is deformed by being pushed down from the position indicated by the dotted line in the figure to the position indicated by the solid line, and the inner leg side fitting portion 5 located inside by the left leg portion 4c ′. By tightening the leg portion 5a, the gouge fastening can be performed firmly.

  In the fitting type folded plate roofing material used in the present invention, the inclined side plate portions 2 and 2 ′ that substantially support the outer goby side fitting portion 4 and the inner gouge side fitting portion 5 are basically arranged in FIG. 1 to a plurality of small steps 2a and 2b are formed, and an overhanging recess 2c referred to as a so-called “ago” that is recessed toward the base portion 1 at the upper end portion adjacent to the horizontal portions 3 and 3 ′. 2c ′ is formed, and these overhanging recesses 2c and 2c ′ function to be engaged with the claw pieces 7 and 7 ′ cut and raised from the side plate of the tight frame 6 as described below. Yes.

  FIG. 4 shows a state in which the roof material used in the present invention is mounted on a metal fitting (tight frame) 6 fixed to the roof base. As is apparent from this figure, the roof material is attached to the tight frame 6 through the claw pieces 7 and 7 ′ projecting from the upper portions on both sides of the tight frame 6. At the same time as dropping the base portion 1 into the bottom of the tight frame 6, the protruding claw pieces 7, 2 c ′ are provided in the protruding concave portions 2 c, 2 c ′ provided at the upper ends adjacent to the horizontal portions 3, 3 ′ of the inclined side plate portions 2, 2 ′. This is done by locking 7 '.

  And it fits so that the outer goby side fitting part 4 of the roof material to construct next may be covered with the inner gobe side fitting part 5 of the roof material of the side previously attached as mentioned above. . Thereafter, as shown in FIG. 2 or FIG. 3, the right leg portion 4a and the left leg portion 4c of the outer goat side fitting portion 4 are subjected to gouge fastening processing by an electric seam processing machine (seamer) (not shown). The side fitting portion 4 and the inner goat side fitting portion 5 are in a state of being firmly fitted to each other as shown by a solid line in FIG. 2 or FIG.

  Further, in the modification shown in FIG. 3, the right leg portion 4 a ′ and the left leg portion 4 c ′ of the outer goby side fitting portion 4 and the leg portion 5 a ′ of the inner goat side fitting portion 5 are formed so as to rise obliquely. Therefore, when using a metal plate having a constant original plate width (for example, 762 mm), the leg portion of the fitting portion can be less than the roof material in which the leg portion of the fitting portion is raised substantially vertically. The peak height to the top of the roof can be increased, and the rigidity and strength against bending of the entire roofing material can be improved.
