JP4287352B2 - Belt for connecting master rope - Google Patents

Description

  The present application relates to a mounting belt that is attached to a pillar when an altitude worker stretches a master rope between pillars to prevent a crash at a construction site.

As an example of a conventional product, there is a rope-like basement rope in which a hook is provided at one end of a rope as shown in FIG. 8, a three-hole ring and a hook are inserted in an intermediate portion, and the other end is connected to the three-hole ring. there were.
When attaching this mounting rope to the pillar, the length between the hooks of the mounting rope can be adjusted by moving the three-hole ring, turning it once or more around the pillar, and hooks at both ends to one end of the master rope It was locked to the provided locking ring or the like.
In the case of a conventional mount rope, it is simply turned around to the pillar, so it will slide down during installation, so that it can be taken by another worker to prevent it from slipping, or a parent rope should be stretched to some extent. One worker was going back and forth between the pillars to raise the lowered mounting rope to a predetermined position.
Therefore, when the master rope was laid, it took time and manpower to increase costs. In addition, the risk of a crash disaster increased when one worker moved over the beam.

In order to solve the problem of the mounting rope, there is a ratchet mechanism fastener disclosed by the present applicant in Japanese Patent Laid-Open No. 2003-41780.
This belt fastener was suitable for the structure of a high-rise building construction. It is a structure with a large separation between the pillar and the outer wall, so there are almost no restrictions when attaching the mounting belt, and because of the thick pillar, the attachment is easy and the ratchet is stretched as the belt length increases. For the purpose of being able to work safely by reducing the protrusion from the pillar, which can be securely tightened by adopting a mechanism, and it may be dangerous for workers walking on the beam if it is large and protrudes from the pillar It was developed and has achieved some results at the construction site of a large high-rise building.
JP 2003-41780 A

Conventional products are large fasteners that employ a ratchet mechanism suitable for the thick pillars of high-rise buildings, and are difficult to use as they are for thin pillars in low-rise buildings.
Moreover, in low-rise houses, the pillars are also thin, and if the ALC outer wall plate is located outside the pillars, there is only a few millimeters between the pillars and the outer walls, and the pillars located at the corners also have a smaller mounting space. It provides a mounting belt having a structure that is compact and less expensive than conventional ratchet mechanism fasteners and that is easy to use in a narrow space during installation and can be securely fixed to a thin column.

  Therefore, in this application, since it must be a small one that is suitable for low-rise housing where the space for mounting the pillars is limited, a toggle mechanism (pull-type clamp) is adopted, and a base belt that can be fixed securely with a simple structure. To get. Further, the adjustment of the belt length corresponding to the size of the column can be easily adjusted as a buckle structure, and the belt is securely clamped to solve the problem.

By adopting the present application as described above, it is a thin column of a low-rise house, and it has a shape, structure, and movable range that fits within the space of the two columns exposed even at the corner where the mounting location (space) is restricted, It can be securely installed.
Therefore, it is possible to safely install the master rope alone without the belt being loosened and the fastening tool falling and falling to the operator's feet.

Detailed examples of the present application:
In the present application, the plate material is bent in a U-shape, one end of the bottom part 11 is folded back to provide a stopper 12, a belt mounting shaft 14 and a belt bending shaft 15 are disposed between the opposite side parts 13, and a spring 16 is provided. a contact fitting 1 comprising providing a lock shaft 17 to keep the protruding state outward from always opposite side portions 13 by distributing,
Similarly, the plate material is bent in a U-shape, and an opening 22 is provided at the bottom 21, and an upper plate 24 provided with a belt insertion hole 23 and a lower plate 25 are connected to the opening 22 by a rivet 26. A lock fitting 2 comprising a sliding plate 27 to form a buckle portion 28, and a receiving portion 30 that is perforated in one of the opposite side portions 29 to receive the protruding portion of the lock shaft 17,
The hook locking ring 33 obtained by bending the plate material into a substantially U shape is formed so that the opposite side portion 13 on the opposite side of the contact fitting 1 to the lock shaft 17 and the opposite side portion on the opposite side of the receiving portion 30 of the lock fitting 2. 29 and the U-shaped end portions of the hook locking ring 3 as the base end portions, the U-shaped inner sides of the contact fitting 1 and the lock fitting 2 are opposed to each other, and the base end portions are hinged 4 and, sewn polymerization unit folded 5 group end belt annulus 51 provided, by inserting the該輪shaped portion 51 in the belt mounting shaft 14 of the contact fitting 1, among the belt middle portion of the contact fitting 1 placed side, guided by the belt bending axes 15, further turn out side of the lock fitting 2, inserted into the belt insertion hole 23 of the buckle portion 28, inserting the belt end leaving the inner side again opening 22 and a structure disposed on the outer side.

  The belt length adjustment of the present application is performed at the buckle portion 28. However, as shown in FIG. 5, the belt 5 has a force acting in the direction of pulling the upper plate 24. It is in a state of being strongly sandwiched between the edges of the opening 22 of the base 21 and is securely fixed without slipping.

5 and 6 show the mounting state of the mounting belt of the present application. FIG. 5 shows a state in which the mounting belt is attached to a 50 mm prism and FIG. 6 shows a state in which it is attached to a 75 mm prism. 12 is applied, the contact metal fitting 1 and the lock metal fitting 2 are brought into a substantially right angle state, and the slack of the belt 5 is removed in this state.
Then, when holding the belt 5 end and the lock fitting 2 and holding it on the column side, the lock fitting 2 rotates around the hinge 4 axis as a fulcrum, the lock shaft 17 is fitted into the receiving portion 30, and the lock fitting 2 is locked. At the same time, the belt tightening is completed.
Then, hooks provided at both ends of the master rope are locked to the hook locking ring 3, and the tensioner of the master rope is operated so as to be stretched between the columns. (Not shown)

  The mounting location (space) of the present application is to attach the ALC outer wall plate to the outside of the column, but there is only a few millimeters gap between the column and the outer wall plate, and adopting a belt so that it can be arranged in the gap, Since only the two surfaces of the pillar are exposed at the corner, the shape, structure, and movable range fit within the space of the minimum two surfaces.

In the removing method of the present application, if the lock shaft 17 is pushed down to be removed from the receiving portion 30 and the end of the belt 5 is pulled to rotate the lock fitting 2, the tightening can be easily released.
Then, the belt 5 is removed from the buckle portion 28, and the belt 5 located on the pillar and the outer wall plate is removed.

  As a general order, the mounting master rope is installed before the ALC outer wall plate is attached to ensure the safety of the worker when the outer wall plate is attached. However, after the outer wall plate is attached, one end is removed. After that, even when attaching again by attaching a sash or the like, since it is a belt type, it can be easily inserted through the gap between the column and the outer wall plate.

  FIG. 7 is a perspective view showing another embodiment of the tightening machine used for the mounting belt of the present application, in which the belt 5 can be easily detached from the buckle portion 28, and the opening 22 is stepwise. The slide plate 27 is notched so that the slide plate 27 can be freely inserted and removed, and can be more easily attached and removed.
