Description

[Detailed Description of the Invention] This invention relates to a handrail device installed between the structures of a gate-type scaffold. The purpose is to propose a handrail device that is easy to install, reliable, and can improve the safety of frame scaffolds.

Traditionally, handrails have been installed between gate-shaped scaffolds to increase safety. However, handrails were not installed between the gate-shaped scaffolding structures, resulting in low safety.

This idea was made in view of the above circumstances. The following will explain the embodiments shown in the drawings.

As shown in FIGS. 1 and 2, this handrail device A is gate-shaped and consists of a handrail rod 1 and vertical rods 2 and 2' pivotally attached to both ends of the handrail rod 1. ', and a sliding tube 4 loosely fitted at one end in the longitudinal direction.

One vertical rod 2 is pivotally connected to a plate-shaped bracket 3 that protrudes horizontally on the outside of the rod body 1', and the other vertical rod 2' is attached to a plate-shaped bracket 3 that protrudes horizontally on the outside of the sliding tube 4. It is pivotally attached to the bracket 3' and is rotatable in the same vertical downward plane in the longitudinal direction of the sliding rod 1. A groove for screw hole sliding is bored in the side surface of the sliding tube 4, and it is slidable in the longitudinal direction, and by screwing the bolt 5, the sliding tube 4 is pressed against the handrail rod 1. Can be fixed.

A holding fitting 6 having an L-shaped cross section is fixed to the end-direction surface of the two brackets 3 and 3', and is opened toward the end of the handrail rod 1 to hold the building site between the two brackets 3 and 3'. It constitutes a recessed portion 7.

A pin hole 8 is drilled at the tip of the vertical rod 2, 2' into which a lock pin for fixing a brace provided at the building site is inserted and locked. Furthermore, on the vertical rods 2 and 2',
A handrail lock pin is provided for the intermediate handrail, and a curved portion is formed at the bottom to serve as both a simple frame and a torii gate form.

This handrail device A has the above-mentioned configuration, and when installing this device on the gate-shaped scaffold B, as shown in FIG.
7 along the inner surfaces of the buildings 9, 9, respectively, and move them in the vertical direction, and fit and lock the lock pins 10, 10 for fixing the braces of the buildings 9, 9 into the pin holes at the tips of the vertical rods 2, It is fixed in the length direction of the building lot 9, that is, in the height position. Next, slide the sliding pipe 4 toward the end, press it, press the building blocks 9, 9 into the recesses 7, 7 of the two holding fittings 6, 6, and tighten the bolts 5. The sliding pipe 4 is fixed and the handrail device A is installed between the building lots 9 and 9.

The structure of this device is as described above. This device holds the building site with the holding fittings at both ends of the handrail rod, and at the same time, a locking pin for fixing a brace is installed in the pin hole at the tip of the vertical rod. It can be installed between gate-type scaffolding structures by fitting and locking.

Therefore, it can be easily attached and detached, and the attached thing will not fall off or shift its position during use, making it possible to improve the safety of the framework scaffold.

A sliding tube having a holding fitting and a vertical rod is attached to one side of the rod main body of the handrail rod, and is slidable in the longitudinal direction of the handrail rod. Therefore, even if the spacing between buildings changes when installing this handrail device on a gate-type scaffold, it can be easily installed to match the spacing (this sliding range is 1219 mm to 1200 mm, 914 mm to 900 mm).
mm, 762mm to 750mm, and 610mm to 600mm to match existing gate-shaped scaffolds. ).

The holding fitting is provided with a recess, making it easy and reliable to attach when holding.

Since the vertical rod is pivotally attached to the handrail rod, the handrail rod can be rotated in the longitudinal plane, and it can be conveniently stored compactly during disassembly and storage.
