Description

Reversible fixture scaffold guardrail stand column clamp

Technical Field

The utility model relates to a scaffold frock piece, concretely relates to can fall formula frock scaffold guardrail stand anchor clamps for the scaffold in shipbuilding field sets up usefulness.

Background

In the existing ship engineering, the problem that the top end of part of an ultrahigh product cannot pass through a factory building gate or equipment is solved after a scaffold platform is arranged. When the high-altitude operation of each professional project of the ship is repaired, a safe and stable construction platform is needed by a constructor. The height of an enterprise factory building or equipment is fixed and unchanged, the height of products accepted by an enterprise is too high sometimes, the height of the products can enter a factory building gate just barely, or the products can pass through high-altitude equipment such as a gantry crane barely, and therefore the top of the products can ensure that a scaffold platform for high-altitude construction of workers cannot pass through due to the fact that the scaffold platform is ultrahigh. Along with the circulation of products, the enterprise scaffold building worker needs to set up and remove the top scaffold platform for many times so that after the platform is set up through a gate or high-altitude equipment, other electric welders, assemblers, painters and other work type construction teams can go up to carry out dry construction, and the repeated setting and dismantling causes the waste of a large amount of manpower and material resources, and causes unsmooth work, incoordination and serious work errors of various work types. Early scaffold frame guardrail stand welds at product top platform edge, can cause hull steel structure surface damage, and the later stage needs to polish in a large number and repair the weld beading welding slag. Another kind of comparatively improved scaffold guardrail stand presss from both sides tight at product top platform edge through the bolt, and its advantage is that can not cause hull steel construction surface damaged, and the repair work is not polished to the later stage, and it is as an organic whole that it is not enough to locate stand railing and bolt anchor clamps, dismantles and need take the whole dismantlement of spanner by the builder, has striden the worker and still can have the problem such as the harmonious mistake of worker between the worker.
