Description

[Technical field]

[0001] The present invention relates to a walkway plate for forming a walkway on a folded plate roof. [Background technology]

[0002] As a walkway installed for maintenance and construction on a folded plate roof, for example, the one described in Patent Document 1 is known. This walkway is installed on the upper surface of a folded plate roof constructed by laying folded plates on the beams of the roof frame in the same direction as the folding lines of the folded plates, and a support material is spanned between at least two adjacent peaks of the folded plate roof, both ends of the support material are fixed using the roof connecting bolts used in constructing the folded plate roof, and a walkway material is installed on the support material in the same direction as the folding lines of the folded plates, and both ends of the fixing band that presses the upper surface of the walkway material in the transverse direction are fixed to the support material by bolt connection. This allows workers performing maintenance and construction on the folded plate roof to walk without being bothered by the uneven shape of the folded plate roof.

[0003] [Patent Document 1] JP 2009-7796 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the walkway of Patent Document 1, both ends of the fixing band that presses the top surface of the walkway material in the horizontal direction are fixed to the receiving material by bolt connections, making it difficult to install the walkway material without any gaps in the direction perpendicular to the fold lines.

[0005] Patent Document 1 also discloses a walkway installed on the top surface of a folded-plate roof constructed by laying folded plates on the beams of a roof frame, in an arrangement perpendicular to the fold lines of the folded plates, in which walkway materials are placed on each peak of the folded-plate roof in an arrangement perpendicular to the fold lines of the folded-plate roof, and both ends of the fixing bands that press the top surface of the walkway material in the horizontal direction are fixed using the roof connecting bolts that were used to construct the folded-plate roof.With this walkway, although the walkway material can be extended in a direction perpendicular to the fold lines, it is difficult to install the walkway material without gaps in the same direction as the fold lines, because both ends of the fixing bands that press the top surface of the walkway material in the horizontal direction are fixed using the roof connecting bolts that were used to construct the folded-plate roof.

[0006] The present invention has been made in consideration of the above circumstances, and has as its object to provide a plate for a walkway that enables the laying of a walkway in both the same direction as the fold lines of a folded plate roof and in a direction perpendicular to the fold lines. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a walkway plate that is installed on the peaks of a folded plate roof via a long intervening member that extends in the same direction as the fold lines of the folded plate roof to form a walkway, wherein a convex portion is formed at one end in the left-right direction and a concave portion that fits into the convex portion is formed at the other end, the convex portion is fixed to one intervening member fixed to one peak of the folded plate roof, and the other end is fixed to another intervening member fixed to the other peak of the folded plate roof, and one edge portion and the other edge portion in the front-to-rear direction are parallel to each other.

[0008] The intervening member may be fixed to the peak portion of the folded plate roof by clamping a seam portion that protrudes upward at the peak portion of the folded plate roof.

[0009] Furthermore, the intervening member may have a groove formed therein, the protruding portion may have an insertion hole formed therein, and the protruding portion may be fixed to the first intervening member by a bolt inserted into the insertion hole being screwed onto a nut of a nut-equipped plate inserted into the groove of the first intervening member. At this time, the other end portion may have a notch formed therein, and the other end portion may be fixed to the other intervening member by a bolt inserted into the notch being screwed onto a nut of a nut-equipped plate inserted into the groove of the other intervening member.

[0010] Furthermore, a bent piece bent downwardly may be formed on the one edge portion or the other edge portion so as not to interfere with the one intervening member and the other intervening member, with the convex portion fixed to the one intervening member and the other end portion fixed to the other intervening member. Effect of the Invention

[0011] According to the walkway plate of the present invention, it is possible to lay the walkway in the same direction as the fold lines of the folded plate roof, as well as in a direction perpendicular to the fold lines. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

[0014] As shown in Fig. 1, the walkway plate 1 according to this embodiment is installed on the peak 2 of a folded-plate roof 4 having a peak 2 and a valley 3 via a long mounting bracket 6 extending in the same direction as the fold lines 5 of the folded-plate roof 4, forming a walkway 7. The mounting bracket 6 is fixed to the peak 2 by clamping the seam 8 protruding upward from the peak 2.

[0015] As shown in Figure 2, the walkway plate 1 is a stainless steel plate having a convex portion 10 formed at one end 9 in the left-right direction (perpendicular to the plane of the paper in Figure 2(b)) of a rectangle, and a concave portion 12 of an approximately inverted concave-convex shape formed at the other end 11 to fit into the convex portion 10, and one (front) edge portion 13 and the other (rear) edge portion 14 in the front-to-back direction (left-to-right direction in Figure 2(b)) are straight and parallel to each other.

[0016] The walkway plate 1 is formed with an anti-slip portion 15 to prevent workers from slipping when walking, and a drainage hole 16 to drain rainwater, etc. The protrusion 10 is formed with an insertion hole 17, the end 11 is formed with a notch 18, and the peripheral portions 13 and 14 are formed with bent pieces 19 and 20, respectively, which are bent downward so as not to interfere with the mounting bracket 4 when the walkway plate 1 is attached to the mounting bracket 6.

[0017] 3, the mounting bracket 6 includes long aluminum split brackets 21 and 22, a bolt 23 that passes through an insertion hole (not shown) formed in each of the split brackets 21 and 22, and a nut 24 that screws onto the bolt 23. A clamping portion 25 is formed at the bottom of the split bracket 21, and a clamping portion 26 is formed at the bottom of the split bracket 22. With the clamping portion 25 and the clamping portion 26 clamping the seam portion 8, the split brackets 21 and 22 are fastened together by the bolt 23 and the nut 24, whereby the mounting bracket 6 is fixed to the peak portion 2 so as to be aligned in the same direction as the fold lines 5 of the folded-plate roof 2.

[0018] At the top of the mounting bracket 6, sandwiched between the split brackets 21 and 22, a groove 27 is formed which is narrow at the top and bottom and wide at the middle. A nut-equipped plate 28 shown in Fig. 4 is inserted into the groove 27. The nut-equipped plate 28 is formed by welding a nut 31 to a plate body 30 in which an insertion hole 29 is formed, so that the nut 31 is aligned with the insertion hole 29. The plate body 30 is inserted into the wide middle part of the groove 27, and at this time the nut 31 is located at the narrow lower part of the groove 27.

[0019] As shown in Figure 5, the convex portion 10 of the walkway plate 1 is placed on the upper surfaces 32, 33 of the split brackets 21 and 22 of one mounting bracket 6 (the left mounting bracket 6 in Figures 5 and 6) fixed to one ridge portion 2 of the corrugated roof 4, and a bolt 35 passing through the insertion hole 17 via a washer 34 is inserted through the insertion hole 29 of a nut-equipped plate 28 inserted into the groove portion 27 of the mounting bracket 6 and screwed into the nut 31, thereby fixing the plate to the one mounting bracket 6.

[0020] In addition, the end 11 of the walkway plate 1 is placed on the upper surfaces 32, 33 of the split brackets 21 and 22 of another mounting bracket 6 (the right-hand mounting bracket 6 in Figures 5 and 6) fixed to the other ridge 2 adjacent to the above-mentioned one ridge 2 of the corrugated roof 4, and the bolt 37 passing through the notch 18 via the washer 36 is inserted through the insertion hole 29 of the nut-equipped plate 28 inserted into the groove 27 of the mounting bracket 6 and screwed into the nut 31, thereby fixing it to the other mounting bracket 6.

[0021] As a result, as shown in Figure 6, the walkway plate 1 is installed so that it spans one mounting bracket 6 and the other mounting bracket 6, and in this state, the bent pieces 19 and 20 do not interfere with either mounting bracket 6.

[0022] When the walkway plates 1 are installed in a line in the same direction to lay the walkway 7 in the same direction as the fold lines 5 of the folded-plate roof 4, the next walkway plate 1 can be fixed to a pair of mounting brackets 6 (one mounting bracket 6 and the other mounting bracket 6) so as to be located in front of the walkway plate 1 already fixed to the pair of mounting brackets 6. At this time, the edge portion 14 of the next walkway plate 1 is parallel to and in contact with (or close to) the edge portion 13 of the already fixed walkway plate 1, and the two walkway plates 1 are installed side by side without any gaps (without any gaps or with a small gap). The next walkway plate 1 may be placed behind the already fixed walkway plate 1 so that its edge portion 13 is in contact with (or close to) the edge portion 14 of the already fixed walkway plate 1.

[0023] When the walkway plates 1 are installed in a line in order to lay the walkway 7 in a direction perpendicular to the fold lines 5 of the folded-plate roof 4, the next walkway plate 1 is fixed to one mounting bracket 6 and the mounting bracket 6 adjacent to the left of the first mounting bracket 6 so that it is located to the left of the walkway plate 1 already fixed to the first mounting bracket 6 and the other mounting bracket 6. At this time, the recess 12 of the next walkway plate 1 fits into and contacts (or is close to) the protrusion 10 of the already fixed walkway plate 1, and the two walkway plates 1 are arranged side by side without any gaps (without any gaps or with a small gap). The next walkway plate 1 may be placed to the right of the already fixed walkway plate 1 so that its protrusion 10 contacts (or is close to) the recess 12 of the already fixed walkway plate 1.

[0024] The walkway plate 1 in this embodiment is installed on the peak portion 2 of the folded-plate roof 4 via a long mounting bracket 6 extending in the same direction as the fold lines 5 of the folded-plate roof 4, forming a walkway 7. A convex portion 10 is formed at one end 9 in the left-right direction, and a concave portion 12 that fits into the convex portion 10 is formed at the other end 11. The convex portion 10 is fixed to one mounting bracket 6 fixed to one peak portion 2 of the folded-plate roof 4, and the end 11 is fixed to another mounting bracket 6 fixed to the other peak portion 2 of the folded-plate roof 4. Since the edge portion 13 of the first plate and the edge portion 14 of the second plate are parallel to each other, when the plates are arranged in the same direction as the fold lines 5 of the folded plate roof 4, the edge portions 13 or 14 are in contact with (or close to) the edge portions 14 or 13 of the adjacent plates for the walkway 1, and when the plates are arranged in a direction perpendicular to the fold lines 5 of the folded plate roof 4, the convex portions 10 or concave portions 12 are in contact with (or close to) the concave portions 12 or convex portions 10 of the adjacent plates for the walkway 1, and the plates for the walkway 1 are arranged in a direction perpendicular to the fold lines 5 of the folded plate roof 4. Therefore, according to the plate for the walkway 1, it is possible to lay the walkway 7 in the same direction as the fold lines 5 of the folded plate roof 4 and in a direction perpendicular to the fold lines 5.

[0025] Here, the mounting bracket 6 is fixed to the peak portion 2 of the folded plate roof 4 by clamping the seam portion 8 that protrudes upward at the peak portion 2 of the folded plate roof 4, and a known mounting bracket for installing equipment, etc. on a folded plate roof can also be used as the mounting bracket 6.

[0026] In addition, a groove portion 27 is formed in the mounting bracket 6, and an insertion hole 17 is formed in the convex portion 10 of the walkway plate 1, and the convex portion 10 is fixed to the mounting bracket 6 by screwing the bolt 35 inserted into the insertion hole 17 into the nut 31 of the nut-equipped plate 28 inserted into the groove portion 27, so that the convex portion 10 can be easily fixed to the mounting bracket 6.

[0027] Similarly, a notch 18 is formed in end 11 of walkway plate 1, and end 11 is secured to mounting bracket 6 by screwing bolt 37 inserted into notch 18 into nut 31 of nut-equipped plate 28 inserted into groove 27 of mounting bracket 6, thereby facilitating securing of end 11 to mounting bracket 6. In this embodiment, notch 18 extends in the left-right direction, so that the mounting position of walkway plate 1 relative to mounting bracket 6 in the left-right direction (extension direction of notch 18) can also be adjusted.

[0028] Furthermore, on the edge portions 13 and 14 of the walkway plate 1, with the convex portion 10 fixed to one mounting bracket 6 and the end portion 11 fixed to the other mounting bracket 6, bent pieces 19 and 20 bent downwardly so as not to interfere with the one mounting bracket 6 and the other mounting bracket 6, respectively, the walkway plate 1 is reinforced by the bent pieces 19 and 20 and the plate thickness can be made thin.

[0029] Although the embodiment of the present invention has been described above, the embodiment of the present invention is not limited to the above, and may be appropriately modified without departing from the spirit of the invention.

[0030] For example, in the above embodiment, the peripheral portions 13 and 14 are parallel in a straight line, but they may be parallel in a curved line, etc., and the bent pieces 19 and 20 may not be formed on both the peripheral portions 13 and 14, but may be formed on one or neither.

[0031] In addition, in order to insert a bolt for fastening to the mounting bracket 6, a notch or the like may be formed in the convex portion 10 instead of a through hole 17, or a through hole or notch or the like may be formed in the end portion 9 instead of the convex portion 10, or a through hole or the like may be formed in the end portion 11 instead of the notch 18, and a handrail 38 may be provided together with the walkway plate 1 as shown in Figure 7.

[0032] Furthermore, the convex portions 10 and concave portions 12 and the edge portions 13 and 14 of the walkway plate 1 may also be changed to various shapes. For example, as shown in Figure 8, the front-to-rear width of the convex portions 10 and concave portions 12 may be narrowed (Figure 8(a)), the edges of the convex portions 10 and concave portions 12 may be curved (Figure 8(b)), the edges of the convex portions 10 and concave portions 12 may be wedge-shaped (Figure 8(c)), the edge portions 13, 14 may be made oblique to the fold lines 5 of the folded plate roof 4 (Figure 8(d)), or the convex portions 10 and concave portions 12 may be moved closer to the rear edge portion 14 (Figure 8(e)).
