Description

  The present invention relates to a stanchion for folding plate roofing work that is removably attached to the folded plate roof at the time of folding plate roofing work, and in particular, a support column for mounting safety equipment, and a support member that supports the support column. The support member is related to a stanchion for folding plate roofing work that spans a goby adjacent to the folded plate roof.

  The stanchions for folded plate roofing work as described above need to be frequently changed to change the attachment position of the stanchions with respect to the folded plate roof in accordance with the progress of the folded plate roofing work. Therefore, as a stanchion for the folded plate roofing work as described above, four fixings for gripping a gob (ridge) formed along the mountain portion of the folded plate roof at the bottom of the support member (base). Each fixing member has two substantially U-shaped gripping pieces each having an upper flange and a lower flange, and bolts and nuts for fastening and fixing the upper flanges of these gripping pieces to the support member, The lower flange of the two gripping pieces opens and closes with the upper flange as a fulcrum by adjusting the tightening of the nut against the bolt, so that the two gripping pieces grip the goby of the folded plate roof and the support member becomes the folded plate roof There is one configured to be able to be switched between a fixing state and a state in which the two gripping pieces release the grip of the folded plate roof against the goby and release the fixing of the support member to the folded plate roof (for example, Patent Document 1). reference).

JP 2009-215736 A

  In the configuration described in Patent Document 1, it is necessary to open and close two gripping pieces using four tools, such as an impact wrench and a spanner, every time the stanchions are rearranged. Therefore, it takes time to change the stanchions, and there is room for improvement in improving construction efficiency. In addition, there is a risk of stagnation of work due to slipping and losing bolts, nuts, tools, etc. during reordering work, and there is room for improvement in this respect from the standpoint of improving construction efficiency.

  In view of this situation, the main problem of the present invention is that the replacement of the stanchions according to the progress of the folded plate roofing work can be performed easily and quickly without using a tool, and the construction in the folded plate roofing work is performed. This is to improve efficiency.

The first characteristic configuration of the present invention is:
In a stanchion for folding plate roofing work comprising a support column for mounting safety equipment and a support member that supports the column, and the support member is stretched over adjacent goby of the folded plate roof.
A pair of fixtures that removably fix both ends of the support member to the goby;
The fixing tool employs a lever-operated toggle clamp mechanism that can be easily switched between a state where the gob is held between the ends of the support member and a state where the holding is released by lever operation. There is in point.

According to this configuration, when the worker attaches the stanchion to the folded plate roof, the support member of the toggle clamp mechanism is operated by operating the lever of each toggle clamp mechanism after the stanchion support member is passed over the adjacent goby of the folded plate roof. The stanchions can be easily attached to the folded plate roof by sandwiching each gob between each end portion of the slab and each toggle clamp mechanism.
In addition, when the worker removes the stanchion from the folded plate roof, the lever operation of each toggle clamp mechanism is performed, and the end of the support member and each goblet clamped by each toggle clamp mechanism are released, so that the stanchion is removed. It can be easily removed from the folded roof.
As a result, the worker can change the stanchion according to the progress of the folding roofing work without using tools such as impact wrench and wrench, or by sliding down bolts, nuts, tools, etc. This can be done easily and quickly without causing a stagnation of work.
As a result, it is possible to improve the construction efficiency while ensuring safety by using a stanchion in the folded-plate roofing operation.

The second characteristic configuration of the present invention is:
The support column is supported by one end portion of the support member, and the pair of toggle clamp mechanisms are provided between the one end portion of the support member for supporting the support column and the other end portion opposite to the one end portion. It is in the point where it is deployed.

According to this configuration, for example, when the support column is supported by the central portion of the support member and the pair of toggle clamp mechanisms are arranged and arranged on both end sides of the support member with the support column interposed therebetween, the operator can When the lever of the toggle clamp mechanism located on the right side is operated, the lever of the right toggle clamp mechanism is operated with the right hand while holding the column with the left hand. When the lever of the toggle clamp mechanism located on the left side of the column is operated, the lever of the left toggle clamp mechanism is operated with the left hand while holding the column with the right hand. That is, when performing lever operation of each toggle clamp mechanism, the effort which changes the hand to operate according to the position of a toggle clamp mechanism will arise.
On the other hand, in the second characteristic configuration of the present invention, the support column is supported by one end portion of the support member, and the pair of toggle clamp mechanisms are arranged adjacent to the center side of the support member. The lever operation of each toggle clamp mechanism can be easily performed with the other hand while holding the column with the other hand. That is, when the lever of each toggle clamp mechanism is operated, there is no need to change the operating hand according to the position of the toggle clamp mechanism.
As a result, it is possible to improve the operability of each toggle clamp mechanism when rearranging the stanchions according to the progress of the folded plate roofing work, thereby further improving the construction efficiency in the folded plate roofing work. Can be planned.

The third characteristic configuration of the present invention is:
It is in the point provided with the diagonal which covers the upper part of the said support | pillar, and the edge part of the said supporting member.

According to this configuration, it is possible to increase the support strength of the support column to which the safety belt is attached via the master rope, thereby improving the safety of the operator in the folding plate roofing work performed using the safety belt. Can be made.
In particular, as a structure of the stanchion, when a structure in which the support column is supported by one end portion of the support member and a single diagonal member is installed on the upper portion of the support column and the other end portion of the support member is adopted, If the stanchion mounting position is set so that the diagonal material is positioned at the opposite side of the column with respect to the area where the operator may fall from the folded plate roof during roofing work, work should be done When a person is about to fall from the folded plate roof, the load at that time can be applied to the diagonal as a tensile force. Thereby, compared with the case where the load when an operator is about to fall from the folded-plate roof acts as a compressive force on the diagonal material, the strength of the diagonal material can be effectively utilized for reinforcing the column. . That is, as compared with the case where a plurality of diagonal members are provided, it is possible to effectively increase the support strength of the support column while facilitating carrying by reducing the weight of the stanchion. As a result, it is possible to improve the safety of the operator in the folded plate roofing work performed using the safety belt attached to the support via the master rope.

The fourth characteristic configuration of the present invention is:
The support member is formed in an H shape in which the both end portions are placed on the gob and the lateral width of the both end portions is wider than the lateral width of the intermediate portion across the both end portions.

According to this configuration, in a state where the stanchion is attached to the folded plate roof, both end portions of the support member formed wide are placed on the goby of the folded plate roof. The backlash of the stanchion with respect to a folded-plate roof can be suppressed more effectively.
As a result, it is possible to improve the stability of the stanchions attached to the folded-plate roof while making it possible to easily and quickly change the stanches according to the progress of the folded-plate roofing operation.

The fifth characteristic configuration of the present invention is:
The said support | pillar exists in the point which the height position of the upper end is set to the low height position which does not interfere with the roof material conveyed on a folded-plate roof using a trolley | bogie.

According to this configuration, when the operator transports a roof material such as a plurality of folded plates on the folded plate roof using a carriage during the folded plate roofing work, the stanchion is not re-ordered. However, it is possible to avoid a possibility that the transportation is hindered by a stanchion attached to the folded roof.
Thereby, conveyance of the roofing material on a folded-plate roof can be performed smoothly, and as a result, the improvement of the construction efficiency in folded-plate roofing work can further be aimed at.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the stanchion 1 for folding plate roofing according to the present invention can be attached to the folded plate roof 2 so as to be refillable. For example, as shown in FIG. 1, a master rope 3B as an example of a safety tool 3 is passed over a plurality of stanches 1 attached to the folded-plate roof 2, and the safety rope 3 is connected to the master rope 3B. The safety belt 4 (see FIG. 2) worn by the operator is attached via the safety block 3A (see FIG. 2) as an example, or as shown in FIG. In addition, by attaching the worker's safety belt 4 to the single stanchion 1 via the safety block 3A, it is possible to ensure the safety of the worker at the time of folding plate roofing work.

As shown in FIGS. 1 to 7, the folded plate roof 2 is continuous with a tight frame 21 welded to each upper surface of a plurality of parallel beams 20 in a direction in which the tight frame 21 extends in a posture extending over the multiple tight frames 21. It is formed by attaching a plurality of folded plates (roofing material) 22 and the like arranged side by side. Each tight frame 21 is formed in a wave shape in which trough portions 21A supported by the beams 20 and crest portions 21B supporting the folded plate 22 are alternately positioned. And it has the hanging element 21C for the gouge fastening extended upward from each peak part 21B. Each folded plate 22 includes a trough portion 22A that enters the trough portion 21A of the tight frame 21, a first crest portion 22C having a lower goby 22B for fastening a gob, and a second crest portion 22E having an upper goby 22D for fastening a goat. It is formed in the shape provided with.
Thereby, at the time of folding plate roofing, the lower gob 22B of each folded plate 22 covers the corresponding hanging element 21C of each tight frame 21, and the upper gob 22D of each folded plate 22 is below the adjacent folded plate 22 After placing the plurality of folded plates 22 on the plurality of tight frames 21 in order from the lower side in the roofing direction so as to cover the goby 22B, the overlapping hanger 21C, lower goby 22B and upper goby 22D are The folded-plate roof 2 can be formed by using an external fastening machine to tighten the gouge. And the goby 2B extended in the longitudinal direction of the folded-plate roof 2 is formed in the mountain part 2A of the folded-plate roof 2 by the above-mentioned goze fastening.
In FIG. 1, illustration of a beam intersecting with the beam 20, a tight frame 21, and the like is omitted.

  As shown in FIGS. 2 to 7, each stanchion 1 reinforces the support member 10 spanned on the adjacent goby 2 </ b> B of the folded plate roof 2, the support 11 for supporting the safety equipment supported by the support member 10, and the support 11. And a pair of fixtures 13 for detachably fixing the support member 10 to the folded plate roof 2. Thereby, each stanchion 1 is comprised so that the change with respect to the folded-plate roof 2 according to progress of the folded-plate roofing operation | work is possible at the time of folded-plate roofing operation | work.

  The support member 10 includes a pair of first members 14 arranged in parallel, and a second member 15 extending over the center of each first member 14. Thus, the support member 10 is formed in an H shape in which the lateral width of both end portions 10A is wider than the lateral width of the intermediate portion 10B across the both end portions 10A. Each first member 14 has a top plate portion 14A placed on the adjacent goby 2B of the folded plate roof 2, and a vertical wall portion 14B that contacts the outer edge of the head 2Ba in the adjacent goby 2B. The cross-sectional shape is formed in an L shape. The second member 15 has a U-shaped cross section so as to have a groove 15 </ b> A extending over the pair of first members 14. Further, the second member 15 extends over the adjacent mountain portion 2 </ b> A of the folded plate roof 2 and has a length that fits between the adjacent goby 2 </ b> B of the folded plate roof 2. Reinforcing flat plate members 16 are welded to both ends of the second member 15 in the longitudinal direction, and the holding pieces 17 provided in the fixture 13 are moved back and forth between the bottom surface of the groove 15A and the flat plate member 16. A permissible opening 18 is formed. The edges of the top plate portion 14 </ b> A of the first member 14 are welded to both ends of the second member 15 in the longitudinal direction and the outer surface of the flat plate member 16.

  The support 11 has a downward U-shaped connecting portion 11 </ b> A provided at the lower end thereof supported by one end of the second member 15 in the support member 10. A ring portion 11B for attaching a safety tool is provided at the upper end portion of the column 11.

  One end of the diagonal member 12 is welded to the upper portion of the column 11. The other end portion of the diagonal member 12 is welded to the flat plate member 16 located on the opposite side of the support member 10 from the support member 10 on the column connecting side. Accordingly, the diagonal member 12 extends over the upper portion of the support column 11 and the end of the support member 10 on the side opposite to the support column support side.

Each fixture 13 employs a lever-operated toggle clamp mechanism 13. Each toggle clamp mechanism 13 includes a fixing member 13A screwed to the second member 15, an operation lever 13B supported slidably by the fixing member 13A, and a sliding rod 13C slidably supported by the fixing member 13A. And a link member 13D for linking the operation lever 13B and the sliding rod 13C. And the clamping piece 17 mentioned above is bolt-connected by the front-end | tip of the sliding rod 13C.
Thus, when the operation lever 13B is swung, each toggle clamp mechanism 13 slides the sandwiching piece 17 together with the sliding rod 13C in conjunction with this operation, so that the sandwiching piece 17 is supported by the support member 10. It is comprised so that it may withdraw from the opening 18 of this. With this configuration, each toggle clamp mechanism 13 has a predetermined operation by swinging the operation lever 13B in a state where the support member 10 of the stanchion 1 is stretched over a predetermined goby 2B adjacent to the folded plate roof 2. Each goby 2B can be easily switched between a state in which each first member 14 of the support member 10 and each holding piece 17 are held and a state in which the holding is released.

  Each sandwiching piece 17 is formed so that its lateral width is inscribed in the groove portion 15 </ b> A of the second member 15. In the state where the goby 2B of the folded-plate roof 2 is held between the first member 14, the tip end portion of the holding piece 17 formed wider is narrower than the head 2Ba of the goby 2B, and the head 2Ba. It acts on the upright portion 2Bb located directly below the head.

With the above configuration, when the worker attaches the stanchion 1 to the folded plate roof 2, first, each first member 14 of the support member 10 in the stanchion 1 is a tight frame in a predetermined goby 2B adjacent to the folded plate roof 2. The support member 10 is hung on the adjacent goby 2B so as to be placed on the upper suspension joint tightening portion. Next, the operation lever 13B of each toggle clamp mechanism 13 is operated so that each holding piece 17 protrudes from each opening 18 of the support member 10 toward each gob 2B. It clamps with each 1st member 14 and each clamping piece 17. FIG. Thereby, the stanchion 1 can be easily attached to the folded-plate roof 2.
When the operator removes the stanchion 1 from the folded roof 2, the operation lever 13 </ b> B of each toggle clamp mechanism 13 is operated to retract each holding piece 17 into the groove of the second member 15, thereby supporting the member. The holding of each predetermined goby 2B by the 10 first members 14 and the holding pieces 17 is released. Thereby, the stanchion 1 can be easily removed from the folded roof 2.
In other words, the worker loses the replacement of stanchion 1 according to the progress of the folded-plate roofing work without using tools such as impact wrench and spanner, or by sliding down bolts, nuts, tools, etc. This can be done easily and quickly without causing a stagnation of work.
As a result, it is possible to improve the construction efficiency in the folded plate roofing operation.

In addition, the stanchion 1 includes a single diagonal member 12 that extends from the upper portion of the support column 11 and the other end portion 10Ab on the opposite side of the support member 10 to the one end portion 10Aa for supporting the support column. The support strength of the support | pillar 11 to which the safety belt | band | zone 4 is attached via the master rope 3B can be raised, and, thereby, improving the operator's safety in the folded-plate roofing work performed using the safety belt | band | zone 4 Can do.
In particular, when the stanchion 1 is attached to the folded-plate roof 2, the mounting posture is set to the position on the opposite side of the column 11 with respect to the region A where the operator may fall from the folded-plate roof 2 during roofing work. If the diagonal member 12 is set so as to be positioned, if an operator is about to fall from the folded plate roof 2, the load at that time can be applied to the diagonal member 12 as a tensile force. As a result, the strength of the diagonal member 12 can be effectively used for reinforcing the column 11 compared to the case where the load when the operator is about to fall from the folded plate roof 2 acts as a compressive force on the diagonal member 12. can do. That is, as compared with the case where a plurality of diagonal members 12 are provided, the support strength of the column 11 can be effectively increased while facilitating carrying by reducing the weight of the stanchion 1. As a result, it is possible to improve the operator's safety in the folded-plate roofing work performed using the safety belt 4 attached to the support 11 via the safety block 3A or the master rope 3B.

  By the way, if the worker attaches his / her own safety belt 4 to the single stanchion 1 via only the safety block 3A (see FIG. 2), the worker uses the master rope 3B that passes over the plurality of stanchions 1. Rather than (see FIG. 1), it becomes easier to change the stanchions 1 with respect to the folded-plate roof 2 according to the progress of the folded-plate roofing operation. As a result, it is possible to improve the construction efficiency while ensuring safety by using the stanchion 1 or the like in the folded-plate roofing operation.

Further, in this stanchion 1, since the pair of toggle clamp mechanisms 13 are disposed adjacent to the intermediate portion 10B between the support column 11 and the diagonal member 12 in the support member 10, the operator can use one hand. With the other hand, the operation lever 13B of each toggle clamp mechanism 13 can be operated without difficulty while holding the column 11 or the diagonal member 12.
And the intermediate part 10B of the support member 10 by which a pair of toggle clamp mechanism 13 is arrange | positioned is the support member 10 which has the length spanned over the adjacent goby 2B of the folded-plate roof 2, and one end part 10Aa of the support member 10 Since the bottom of a wide triangular space formed between the support 11 supported by the support member 10 and the diagonal member 12 extending between the upper portion of the support 11 and the other end 10Ab of the support member 10 is formed. When operating the operation lever 13B of each toggle clamp mechanism 13, it is possible to avoid the possibility that the operation lever 13B interferes with the diagonal member 12 and the operation of the operation lever 13B is hindered.
As a result, it is possible to improve the operability of each toggle clamp mechanism 13 when changing the stanchion 1 according to the progress of the folded-plate roofing work, thereby improving the construction efficiency in the folded-plate roofing work. Can be further achieved.

Further, in this stanchion 1, the shape of the support member 10 is such that the lateral width of both end portions 10A placed on the adjacent goby 2B of the folded roof 2 is wider than the lateral width of the intermediate portion 10B across the both end portions 10A. Since the stanchion 1 is attached to the folded plate roof 2 because it is H-shaped, both end portions 10A of the support member 10 formed to be wide are placed on the goby 2B of the folded plate roof 2. Thereby, the rattling of the stance 1 with respect to the folded-plate roof 2 in the width direction of the support member 10 can be suppressed more effectively.
As a result, the stability of the stanchion 1 attached to the folded plate roof 2 can be improved while allowing the stanchions 1 to be rearranged easily and quickly according to the progress of the folded plate roofing operation.

Furthermore, in this stanchion 1, when the shape of the supporting member 10 is the above-mentioned H type, when the stanchion 1 is attached to the folded-plate roof 2, each 1st which contacts the head outer edge of each goby 2B. The vertical wall portions 14B of the members 14 are also wide in width. Thereby, rattling around the vertical axis of the stanchion 1 with respect to the folded plate roof 2 can be effectively suppressed, and the stability of the stanchion 1 attached to the folded plate roof 2 can be improved.
And each clamping piece 17 which clamps the goby 2B of the folded-plate roof 2 between each 1st member 14 is also formed in the width | variety wide as mentioned above, Therefore The clamping range when the goby 2B is clamped between the first member 14 and the clamping piece 17 can be widened. Thereby, the stanchion 1 can be attached to the folded roof 2 more stably and firmly.
Moreover, in the state where the goby 2B of the folded plate roof 2 is held between the first member 14 and the holding piece 17, as described above, the front end portion of each holding piece 17 acts on the standing part 2Bb of the goby 2B. In the unlikely event that a tensile force acts on the upper portion of the stanchion 1 because the operator is likely to fall from the folded roof 2, the tip of the sandwiching piece 17 is caught on the head 2Ba of the goby 2B and the tensile force is applied. I will resist. And since the clamping piece 17 caught on the head 2Ba of the goby 2B is formed wide, the deformation of the goby 2B due to the catch can be suppressed.
As a result, the stanchion 1 can be attached to the folded-plate roof 2 more preferably and firmly. As a result, even if an operator is likely to fall from the folded-plate roof 2, the stanchion 1 is folded into the folded-plate roof. It is possible to avoid the possibility that the operator falls off the ground 2 and falls to the ground.

  Incidentally, the stanchion 1 having the configuration exemplified in the present embodiment is a folded plate in which 85 kg weight attached to the ring portion 11B of the support column 11 via the safety block 3A and the safety belt 4 is attached to the folded plate roof 2. When a strength confirmation test for dropping from the roof 2 was performed, it was confirmed that the state attached to the folded-plate roof 2 was maintained.

As shown in FIG. 8, a plurality of guide rails 6 for guiding the carriage are attached to and detached from the folded-plate roof 2 in order to enable conveyance of the folded board 22 using the plurality of carriages 5 on the folded-plate roof. It is laid as possible. And the support | pillar 11 sets the height position of the upper end to the low height position which does not interfere with the folded plate 22 conveyed on the folded plate roof using the several trolley | bogie 5 guided with each guide rail 6. FIG. Has been.
Thus, when the operator carries a plurality of folded plates 22 using the carriage 5 on the folded plate roof during the folded plate roofing work, the refilling of the stanchion 1 is not necessary. It is possible to avoid the possibility that the transportation is hindered by the stanchion 1 attached to the folded plate roof 2.
As a result, the folded plate 22 can be smoothly transported on the folded plate roof, and as a result, the construction efficiency in the folded plate roofing operation can be further improved.
