JPS5924764Y2 - Handrail support on temporary pedestal - Google Patents

Description

[Detailed description of the invention] This invention utilizes steel materials such as H-shaped steel piles to create heavy temporary constructions such as truck entry trestles or trolley piers for the entry of transport vehicles and heavy machinery, from the lining plate. This invention relates to handrail supports to prevent accidents from falling.

Conventionally, handrail supports used for this type of use are often welded to horizontal members on steel-frame desks or simply tightened with bolts.

For this reason, the former consumes significant amounts of materials, is uneconomical, and is highly dangerous.

In addition, the latter particularly has problems such as damage to the handrail support or displacement around the bolts due to lateral displacement of the lining board (deck).

The purpose of the handrail post of this invention is to overcome the drawbacks of the above-mentioned conventional construction methods.

An example of the handrail support according to this invention, which is related to the above object, will be explained with reference to the drawings.

Reference numeral 1 denotes a post main body, 2 a handrail support metal fitting provided on the upper part of the post main body, and 3 a clamping part provided at the lower part of this post main body 1, which forms a horizontal clamping groove 4 on the side surface and the clamping part. The lining plate support has a piece 5 protruding along the upper side of 3.

Reference numeral 6 denotes a clamping bolt screwed from the upper piece 3a of the clamping part 3 toward the clamping groove 4, and if it is a bi-tension bolt with a protrusion at the tip, it can be strongly tightened with effective biting force against steel materials. .

Reference numeral 7 denotes a female thread into which this clamping bolt 6 is screwed, and 8 and 8 denote two clamping receiving parts protruding from the lower piece 3b of the clamping part 3 facing the clamping bolt 6. If a bi-tension with a tip projection is used, the same effect can be obtained.

The means for arranging the clamping receiving parts may be in any position around the clamping bolt 6, and as long as there are two or more, the metal fittings can rotate around the clamping bolt 6. disappears.

As shown in Figs. 5 and 6, the handrail support of this invention with the above structure is constructed by erecting a lining plate C on the horizontal member B on the steel frame shaft A, and then attaching the support main body to the side of the lining plate C. The clamping groove 4 of the clamping part 3 is inserted into the flange end face of the horizontal member B in order to abut the piece 5 of the lining plate support No. 1, and the clamping bolt 6 is tightened from above.

Furthermore, a handrail rod is attached to the upper part of the main column 1 by means of a handrail rod support fitting 2.

Note that E indicates the toe plate.

The handrail support of this invention as described above is more versatile, more economical, and safer than the conventional welded support.

Also, compared to something that is simply tightened with bolts, there is no slippage or rotation about the bolt, and it can be securely attached by coming into contact with the side surface of the lining plate.

In particular, since two or more clamping receiving parts are disposed in a protruding manner opposite to the clamping bolt, attachment to the steel material becomes more reliable.

Therefore, it is very safe as a handrail support for preventing falls on a heavy temporary gantry.

Also, in terms of construction, a highly reliable metal fitting can be provided by tightening only the clamping bolts from above.

Claims (1)

[Scope of utility model registration request] A clamping part having a horizontal clamping groove is provided at the lower part of the column on which the handrail is attached, and a piece of the lining board support is provided along the upper side of the clamping part, and the clamping part is clamped from the upper part of the clamping part. A handrail support for a temporary gantry, characterized in that a clamping bolt is threaded toward the groove, and two or more clamping receivers are arranged to protrude from the lower part of the clamping part facing the clamping bolt.
