Description

[Detailed description of the device]

[Field of Industrial Application] [0001] The present invention is capable of detaching mutual side edges of a covering sheet when a covering sheet is stretched on a scaffolding constituent member in order to ensure safety during construction at a construction site. The present invention relates to a cover sheet connecting clasp for connecting and fixing a side edge of a cover sheet to a scaffold constituting member such as a metal pipe constituting a scaffold in a detachable manner.

[Prior Art] [0002] Conventionally, a safety cover sheet is stretched at a construction site by wire or rope attached to a metal ring on a side edge of a cover sheet adjacent to a metal ring attached to a side edge of each cover sheet. The scaffold component constructed on the outside of the building under construction is covered with a covering sheet by connecting it to the scaffold component constructed of iron pipes and fixing it. Had secured the safety of.

[Problems to be Solved by the Invention] A large-scale building is used as a covering sheet tensioning means for connecting side edges of the covering sheet using a conventional wire or rope and fixing the covering sheet to a scaffolding constituent member. In this case, a large number of cover sheets are used, and a large number of metal rings are attached to each cover sheet. Therefore, when tensioning the cover sheets, insert wires, ropes, etc., into the metal rings one by one. The work of connecting and the work of removing the wires, ropes, etc. that were tied at the time of removing the coated sheet were extremely inefficient because they required a large number of work steps. In particular, since the installation and removal of the covering sheet in the construction of high-rise buildings is often disturbed by wind and rain, connecting and disconnecting with wires or ropes has also been a factor that reduces the work efficiency at the construction site.

[Means for Solving the Problems] The present invention uses a conventional wire, rope or the like by using a dedicated connecting band in order to efficiently perform the tensioning and removing operations of the covering sheet. It solves the problem of the means. That is, one end side of the soft resin strip is formed as a connecting end portion and the other end side is formed as a fitting end portion, and the connecting end portion is provided with a plurality of fitting holes intermittently, and Along with the multiple fitting grooves provided on both sides of the dowel hole in the longitudinal direction, it is continuous, and there is a notch continuous with the fitting groove on the tip side at the center of the tip of the connecting side that is inclined and protrudes toward the fitting groove. The fitting end is formed by intermittently projecting a plurality of fitting bodies that fit into the fitting holes, and is connected by the connecting portions that fit into the cuts and fitting grooves, and is fitted to the tip. It is a covering sheet connection clasp for construction work with a side tip. The fitting body protruding from the fitting end is formed in a spherical shape or a hemispherical shape.

[Operation] The operation will be described with reference to FIGS. 6 and 7. The present invention is bent at the time of use, and the plurality of fitting bodies 6 and the connecting portions 7 of the fitting end portion 2 are fitted into the plurality of fitting holes 4 and the fitting groove 5 of the connecting end portion 1, respectively, as shown in FIG. By doing so, the fitting end portion 2 is connected to the connecting end portion 1 to form a ring shape. At this time, the notch 3 at the center of the connecting-side tip portion 8 that is inclined and protrudes serves as a guide into which the connecting portion 7 of the fitting end portion 2 is fitted. Therefore, by widening the tip end side of the notch 3, further fitting can be achieved. It will be easier.

When the present invention is used at a construction site, as shown in FIG. 7, the fitting end portion 2 on one end side is inserted into the metal ring 11 attached to the side edge portion of one covering sheet 10. Then, the back side of the scaffolding component 12 is rotated and inserted into the metal ring 11 of the side edge of the adjacent covering sheet 10, and after tightening, the fitting end 2 is fitted into the connecting end 1 to be connected. Thereby, the side edge portions of the cover sheet 10 can be easily connected to each other, and the side edge portions of the cover sheet 10 can be fixed to the scaffold constituting member 12. Therefore, it is possible to efficiently connect and fix the metal rings, which are mounted on the side edges of the plurality of covering sheets, and the scaffolding members.

To remove the fitting end 2 and the connecting end 1, the fitting-side tip 9 of the fitting end 2 is pulled in the detaching direction, so that the fitting body 6 and the connecting portion 7 are fitted into the fitting hole 4 Also, it can be easily pulled out from the fitting groove 5 and removed.

[Embodiment] An embodiment shown in FIGS. 1, 2, 3, 4, and 5 will be described. One end side of the flexible flexible resin band body is configured as the connecting end portion 1 and the other end side is configured as the fitting end portion 2. As shown in FIGS. 4 and 5, a plurality of fitting holes 4 penetrating through the connecting end portion 1 are formed in a row and are intermittently formed, and each fitting hole 4 is provided with a plurality of fitting holes provided on both sides in the longitudinal direction. A notch 3 is provided at the center of the connecting-side tip portion 8 which is continuous with the groove 5 and which is inclined and protrudes toward the fitting groove 5 side, and whose tip side is wide and which is continuous with the fitting groove 5 on the tip side. The fitting end 2 has a plurality of fitting bodies 6 fitted in a fitting hole 4 formed in the connecting end 1 and arranged in a row so as to project in an intermittent manner. It is made continuous by the connecting portion 7 fitted in 5, and the tip is provided with a fitting-side tip 9 used for removal and fitting.

The fitting body 6 is formed into a spherical shape or a hemispherical shape, and the connecting portion 7 is formed into a circular cross section, so that the fitting end 4 and the fitting groove 5 of the connecting end portion 1 can be easily fitted and removed. Become.

[Advantage of the Invention] The present invention connects the side edges of the covering sheet to each other and the scaffolding component by simply and firmly connecting the connecting ends and the fitting ends at both ends. The cover sheet can be stretched efficiently to ensure safety at the construction site by fixing it by fixing it.When removing the cover sheet, pull the tip of the mating end to fit it. Since the mating end and the connecting end can be easily separated, the site work involved in the construction work can be greatly reduced. In addition, resin molding facilitates large-scale production and can be used repeatedly, which is extremely economical.
