Abstract

PROBLEM TO BE SOLVED: To provide an attachment fitting for a protective net for high place work, which enables a hook for attachment of the protective net to a beam to be easily attached to and detached from the beam in the high place work on a wooden building site and the like, and which prevents scratches from being left on the beam.SOLUTION: An attachment fitting for a protective net for high place work has a saddle-like fitting body 20 that is elongated along top and side surfaces of a beam 10 for attaching the protective net 30 for the high place work. At least one tip of the fitting body 20 is provided with a hook 22. A rope 31 for surrounding the periphery of the protective net 30 is detachably hooked to the hook 22.

Description

  The present invention relates to a mounting fitting for a protective net for preventing a worker, a building material, and the like from falling in a high place work such as a wooden construction site.

  For example, in wooden construction, there is a state in which the ceiling of the first floor, in some cases the floor of the second floor, and the ceiling and roof of the second floor are not blocked in the initial stage of building a frame such as a pillar or a beam. When working on the 1st and 2nd floor beams, a protective net is attached to the space formed by each beam extending in the vertical and horizontal directions to prevent the falling of workers and building materials. Yes.

  Conventionally, the protection net is attached by attaching a plurality of hooks to the side surfaces of the beam at appropriate intervals by screwing or the like, and suspending a rope surrounding the protection net around these hooks.

However, the method of attaching the hook to the side surface of the beam by screwing or the like as described above has a drawback that it takes time and labor to attach and remove the hook, and the beam remains damaged.
Therefore, an object of the present invention is to provide a mounting bracket for a protective net for working at high places, which makes it possible to easily attach and detach the hook as described above and does not leave any damage to the beam.

In order to solve the above problems, the first invention is a mounting bracket for a protective net for working at high places, and a hook-shaped bracket main body extending along the upper surface and the side surface of the beam to which the protective net is attached, and the bracket main body A protective net mounting bracket for a work at high places, comprising a hook that is provided at at least one of the tip ends of the cable and detachably hooks a rope that surrounds the periphery of the protective net.
According to a second aspect of the present invention, there is provided a mounting bracket for a protective net for working at heights, wherein the hook is detachably provided on the bracket main body.
Furthermore, the third invention is characterized in that the tip of the hook is spirally inclined with respect to the former end side portion of the hook and extends to the side of the former end side portion. This is a mounting bracket for a protective net for the machine.

According to the first invention or the third invention, the hook for hanging the rope surrounding the protective net is provided on the hook-shaped metal fitting main body extending along the upper surface and the side surface of the beam. The attachment and detachment can be easily performed, and the beam is not damaged and the beam is not damaged.
Further, according to the second invention, since the metal fitting main body and the hook are configured separately, an effect that manufacture is easy can be obtained.
Furthermore, according to the third aspect of the invention, an effect is obtained in which the rope surrounding the protective net does not bounce off the hook.

It is a partial top view which shows one Embodiment of this invention. It is sectional drawing by the AA line of FIG. It is a partially expanded front view which shows other embodiment of this invention. It is sectional drawing by the BB line of FIG.

One embodiment of the present invention is shown in FIGS.
FIG.1 and FIG.2 is a figure which shows a part of house in the middle of construction. In FIG. 1, reference numeral 10 denotes a beam, which is provided at the upper end of the column 11 as shown in FIG. In FIG. 2, 12 is a base, 13 is a foundation, and the beam 10 is for forming a ceiling on the first floor or a floor on the second floor of the house.

  In FIG. 1, a plurality of beams 10 extend vertically and horizontally, and in FIG. 1, three rectangular spaces 14A, 14B, and 14C are formed at the upper left, lower left, and right. A plurality of mounting brackets 20 according to the present invention are placed on each beam 10. These mounting brackets 20 are disposed on the beams 10 at positions close to the corners of the spaces 14A, 14B, and 14C, respectively, and are further disposed at an appropriate interval as necessary.

  As shown in FIG. 2, the mounting bracket 20 includes a hook-shaped bracket main body 21 extending along the upper surface and the left and right side surfaces of the beam 10, and hooks 22 provided at the left and right tip portions of the bracket main body 21, respectively. The rope 31 surrounding the protective net 30 is detachably hung on the hook 22. Note that the hook 22 may be provided only at one end of the metal fitting body 21.

  Next, the operation of the mounting bracket 20 will be described. The mounting bracket 20 has the bracket main body 21 formed in a bowl shape as described above, and is formed so as to be simply placed on the beam 10. The beam 10 is not damaged, and therefore, the beam 10 is not damaged.

  Further, if the mounting bracket 20 is arranged at a position close to the corners of the spaces 14A, 14B and 14C as described above, the mounting bracket 20 can be positioned even if the mounting bracket 20 is not fixed to the beam 10 with screws or the like. There is no deviation, and the load acting on the protective net 30 can be received.

"Other embodiments"
3 and 4 show another embodiment of the present invention, and the metal fitting body 21A of the attachment metal fitting 20A extends along the upper surface and the left and right side surfaces of the beam 10 like the metal fitting body 21 described above. As shown in FIG. 4, the left and right tip portions 21B are inclined and extended away from the side surface of the beam 10, and an S-shaped hook 22A is provided in the hole 21C opened there. It is designed to be detachable.

  Thus, if the metal fitting main body 21A and the hook 22A are configured separately, the manufacture becomes easy. If holes 21C are provided at both ends of the metal fitting body 21A as shown in the drawing, the hooks 22A can be appropriately provided on either one or both of the left and right sides of the metal fitting body 21A.

Further, as shown in FIG. 3, the hook 22A has a distal end side portion 22a that is spirally inclined with respect to the original end side portion 22b, and the distal end side portion 22a has an original end portion as shown in FIG. It extends to the side of the side portion 22b. If comprised in this way, the rope 31 surrounding the circumference | surroundings of the protection net | network 30 will not rebound and will not remove | deviate from hook 22A.
If the hook 22 of the mounting bracket 20 shown in FIGS. 1 and 2 has the same shape as the hook 22A shown in FIGS. 3 and 4 and is integrally formed with the bracket main body 21, the rope 31 rebounds. Needless to say, it is possible to eliminate the breakout caused by.
