JPS5919087Y2 - handrail holder - Google Patents

Description

[Detailed description of the invention] This invention has a support section, a pair of parallel arm rods, and a stay attached to a handrail holder that is rigidly connected to each other. When a handrail is installed slightly above the eave, the handrail can be easily attached to a post installed below the eaves, and the purpose is to ensure that the impact load received during a fall is supported without buckling. A specific example will be detailed below with reference to the drawings.

Reference numeral 1 denotes a support column, and locking tools 2 and 3 are provided protrudingly at appropriate positions on the upper end and side surface.

This locking device may be a so-called gravity lock, which is engaged by springing a non-return pawl and climbing over it, and released by pushing the pawl.

Arm rods 4 and 5 of equal length that project parallel to the sides are fixed to the lower part of the support column 1, and clamps 6.
7 will be provided.

These clamps have an arc-shaped piece that hugs the outer periphery of the column P and is fastened to the other piece with bolts and nuts.

The length of both arm rods 4 and 5 is made longer than the horizontal dimension from the installation position of the support P to the eaves.

The arm rods 4 and 5 are also connected at both ends by stays 8 parallel to the support portions 1 which are separately fixed to the arm rods 4 and 5, respectively, and are positioned relative to each other.

In the drawings, 11 is the building, 12 is the roof, 13 and 14
15 is a locking tool protruding upward from the upper surface of the arm rod 4,
It locks another handrail.

G is the ground and 16 is the road board.

The illustrated handrail receiver can be installed directly on the ground G or under the eaves 14.
Post P installed above and secured to building 11 by wall connection
Then, use clamps 6 and 7 to firmly fix arm bars 4 and 5.

The column 1 is now fixed at two points spaced apart on the column P, making it stable, and due to the lengths of the arm rods 4 and 5, it is positioned outward from the eaves 13.

At this time, the locking tool 3 is positioned above the eaves 13.

These handrail receivers are installed along the eaves at appropriate intervals, and the handrail is constructed and locked between adjacent handrail receiver locking tools 2, 2 and between 3, 3.

This creates a handrail near the eaves, which prevents workers from falling, and makes work safer by grabbing the handrail when working at the eaves.

The load that the handrail receiver receives due to grasping by a working tool or falling of a working tool can be sufficiently withstood by the frame structure made up of the column 1, arm rods 4 and 5, and stay 8, and the two-point support provided by the clamp 6.7.

According to the present invention, a pair of arm rods are fixed to the lower part of the support section, project laterally, are longer than the horizontal dimension from the position of the support support to the eaves, are of equal length, and are parallel to each other. Since the mutual spacing is determined by the support part fixed to the support part and the parallel stay, this part forms a rigid frame structure.
It has a high resistance to buckling, and even if the support is installed near the building to increase its stability, the support can be installed outside the eaves, and therefore the support can be attached extremely stably to the support. By erecting and locking the handrail between the locking devices of adjacent handrail holders without causing it to stick or wobble, the handrail can be easily placed near the eaves, thereby fully protecting the safety of the work tools. It has various effects such as being able to be used repeatedly and of course being able to be used repeatedly.
