Therefore, the structural features and functions of the folded-plate roof can also be utilized to easily install the folded-plate roof with good workability. The materials necessary for installing the walkway W2 are also convenient and economical enough that only the fixed band 8 is required.

As described above, the corridors W1 and W2 of the present invention can be freely installed after the folded-plate roof is completed. Therefore, it is not necessary to examine the corridor installation at the stage of the steel frame drawing of the roof. Can be arranged with free route.
And the walkway W1 installed in the same direction as the crease of the folded plate 3 as in the invention according to claim 1, and the walkway installed in an arrangement orthogonal to the crease of the folded plate 3 as in the invention according to claim 2. When W2 is installed in an arrangement where it can be walked to each other at necessary points, as shown in FIG. W1 and W2 can be installed lightly. Therefore, when these corridors W1 and W2 are used, it is possible to safely and freely walk on the roof for checking or repairing whether the folded-plate roof is worn out or damaged, or leaks.

The corridor W1 installed on the upper surface of the folded plate roof in the same direction as the folding line of the folded plate 3 bridges the receiving material 5 straddling at least two adjacent mountains of the folded plate roof, and both ends of the receiving material 5 are The roof connecting bolt 4A or 4B used for the construction of the folded plate roof is fixed.
Then, both ends 8a of the fixing band 8 on which the corridor material 7 is laid on the receiving member 5 in the same direction as the folding line of the folded plate 3 and the upper surface of the corridor material 7 is pressed in the transverse direction, The receiving material 5 and the bolt 9 are joined and installed.

The walkway W2 installed in an arrangement perpendicular to the folding line of the folded plate 3 is arranged to be orthogonal to the folded line of the folded plate roof, and the walkway material 7 is placed on the top of each mountain of the folded plate roof. Both ends 8a of the fixing band 8 that presses the upper surface of the material 7 in the transverse direction are fixed and installed by using the connecting bolt 4A or 4B for roof used for constructing the folded plate roof.
Thus, a state where the walkway W1 (FIG. 1) installed in the same direction as the folding line of the folded-plate roof and the walkway W2 (FIG. 6) installed in an arrangement orthogonal to the folding line of the folded-plate roof can be walked with each other. By connecting to, the walkways W1 and W2 can be installed vertically and horizontally on the upper surface of the folded roof (FIG. 9).

FIG. 1 partially shows an embodiment of a walkway W <b> 1 installed on the folded plate roof in the same direction as the folding line of the folded plate 3.
As shown in FIG. 5, this folded plate roof is usually prepared by being fixed to the upper surface of the steel beam 1 constituting the roof frame, and a tight frame having a wave shape substantially the same shape and the same size as the folded plate section. 2 is formed by superimposing piles of metal folded plates 3 formed on a substantially V-shaped half-and-half type or a substantially W-shaped half-and-half type by processing a steel plate or the like. In a place where 2 is present, the tight frame 2 and the two folded plates 3 stacked on the tight frame 2 are connected together with a roof connecting bolt 4A used upward. In addition, at the position where the folded plates need to be connected to each other even between the spans of the steel beam 1 and the tight frame 2, the two folded plates 3, 3 are connected together with the roof connecting bolt 4B used upward. A folded roof is built. Incidentally, the span of the steel beam 1 and the tight frame 2 is usually about 3 to 7 m, the pitch between the peaks of the metal folded plate 3 is usually about 45 cm, the height of the mountain is about 200 mm, and the plate thickness is 0.6 to 1. It is about 2 mm.

  In installing the corridor W1 in the same direction as the folding line of the folded plate 3 as shown in FIG. 1 on the upper surface of the folded plate roof constructed as described above, as described in detail in FIGS. In the case of the present embodiment, the hat type shown in FIG. 3 is arranged across two adjacent mountains of the folded plate 3 (however, not limited to the two mountains, but may be a plurality of two or more mountains). The receiving member 5 using light weight steel in an inverted state is bridged, and the both ends of the receiving member 5 are the above-described roof connecting bolts using the inverted hat-shaped groove bottom portion upward for the construction of the folded plate roof. The nut 6 is fastened and fixed firmly using either 4A or 4B. That is, in the longitudinal direction of the walkway W1, the receiving member 5 arranged at a pitch suitable for supporting the walkway material is selected by using either of the roof connection bolts 4A or 4B at a position suitable for the arrangement, Fix both ends.

On the receiving material 5, a walkway material 7 is installed in the same direction as the folding line of the folded plate 3. Incidentally, the corridor material 7 used here does not indicate a specially-designated material, but is basically used in the roof construction site such as a passage member described in JP-A-10-8709 or an existing scaffold board. It is sufficient if it can be used with existing ones.
The walkway material 7 constructed on the receiving material 5 is fixed by fixing both ends 8a of the fixing band 8 pressing the upper surface of the walkway material 7 in the transverse direction to the flange portion of the receiving material 5 with bolts 9. Has been. That is, the arrangement of the fixed band 8 is made to coincide with the position of the receiving material 5. As the fixing band 8, a belt-like thin steel plate having a combined width of about 100 mm, which is also in the field, can be used. As shown in FIG. 1, the receiving member 5 and the fixed band 8 are installed with an interval P of about 1.5 m in the longitudinal direction of the walkway material 7 with the length of the walkway material 7 being about 4 m. In addition, the code | symbol 10 in FIG. 1 has pointed out the connection part of the corridors 7 mutually. The structure of the connecting portion 10 will be described later with reference to FIG. The interval between the connecting portions 10 in FIG. 1 is naturally provided for every 4 m of the length of the one walking material 7.

  Since it is as above-mentioned, the walkway W1 of a present Example bridges the receiving material 5 between the at least two adjacent mountains of a folded-plate roof, and uses either of the connection bolts 4A or 4B for roofs for the both ends. Since the walkway material 7 is constructed on the receiving material 5, the route and place of installation can be arbitrarily selected and installed with a high degree of freedom. Needless to say, by removing the bolt 9 to which the fixing band 8 is fixed and further removing the receiving member 5, the walkway W1 can be removed or the installation route can be changed freely.

Next, based on FIGS. 6-8, the Example of the corridor W2 installed in the arrangement | positioning orthogonal to the crease of the folded plate 3 based on the invention described in Claim 2 is described.
Also in the case of the present embodiment, assuming the folded plate roof constructed as shown in FIG. 5 as an example, the upper surface of the folded plate roof is orthogonal to the folding line of the folded plate 3 as shown in FIG. In installing the walkway W2 in the arrangement, the walkway material 7 is first placed so as to straddle the tops of the folded plate roofs. And in the longitudinal direction of the walkway material 7, it is the position for every mountain peak which opened the 1 or several space | interval (every other space | interval in the Example of FIG. 6) by the unevenness | corrugation of a folded-plate roof, Comprising: As shown in FIG. 7, by selecting the position where the connecting bolt 4A or 4B is present, both ends 8a of the fixing band 8 pressing the upper surface of the corridor material 7 in the transverse direction are connected to the roof connecting bolt 4A or The walkway W2 is installed by tightening and fixing the nut 11 using any of 4B.

  In addition, FIG. 8 has shown the connection structure of the walk material 7 butt-connected in the longitudinal direction. In the illustrated connection structure, the end portions of the walkway materials 7 and 7 that are connected to each other are fitted and connected to the cylindrical connection device 10, and the connection device 10 is connected to each of the walkway materials 7 and 7 with a set screw 12. The connection structure is stabilized by fixing to the end. This connection structure is similarly implemented as the above-described connection structure 10 for the walkway material of the first embodiment.

  Also in the case of the present Example 2, the installation route and installation place of the corridor W2 can be chosen arbitrarily and can be installed with a high degree of freedom. Further, by loosening and removing the nut 11 of the fixed band 8 that presses the upper surface of the corridor material 7 in the transverse direction, it is possible to easily remove the corridor W2 or change the installation route freely. There is also.

  FIG. 9 shows the corridor W1 installed in the same direction as the folding line of the folding plate 3 of the first embodiment described above, and the arrangement perpendicular to the folding line of the folding plate 3 described in the second embodiment. Necessary and sufficient arrangement and position over the entire surface of the wide folded-plate roof by connecting the walkway W2 to the necessary route on the folded-plate roof and connecting them so that they can walk between each other. The walkway W1 and W2 which satisfy | fill is satisfy | filled the Example installed vertically and horizontally.

  Although the present invention has been described based on the illustrated embodiment, the present invention is not limited to the scope of the illustrated embodiment. The present invention includes modifications and applications including design changes made by those skilled in the art as needed without departing from the scope and spirit of the present invention. For example, with regard to the heat insulation and waterproofing treatment of the folded-plate roof, it is to be noted that construction with a known spraying system or installation of handrails as required for the walkways W1 and W2 is also carried out as necessary.
