Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a corrugated plate construction device used for tightening fasteners when attaching corrugated plates used for the roofs or walls of various structures to a main building or crosspiece. An object of the present invention is to provide a corrugated plate construction device which is attached to a tightening tool and can extremely easily and quickly fasten fasteners such as VV screws, self-tapping screws, or driving screws.

Previously, when installing corrugated boards, hook bolts were used and nuts were manually installed, but this corrugated board construction work is
Excessive tightening can crush the corrugated plate, while insufficient tightening can cause leaks, so a skilled worker is required to properly tighten the corrugated plate, resulting in low work efficiency. In recent years, corrugated plates have been installed using drill screws instead of hook bolts due to the lack of skilled workers and the need to shorten construction time due to rising labor costs.

However, general-purpose electric rotary tools used for tightening drill screws only have a simple rotational drive mechanism, and electric rotary tools developed specifically for drill screws have a clutch mechanism, but an adjustable knob. It does not have a torque control mechanism.

Therefore, when performing corrugated plate construction work with drill screws using these general-purpose or dedicated electric rotating tools,
Excessive tightening could crush the ridges of the corrugated plate and, in extreme cases, destroy the corrugated plate.

In order to prevent such excessive tightening, a special drill screw with a stopper installed at an appropriate position on the screw shaft according to the peak height of the corrugated plate has been developed. If the thread diameter is small, the internal thread may break due to excessive torque, or if the support member of the corrugated plate is thin, the internal thread may be tapped into the support member due to the impact when the stopper comes into contact with the support member and suddenly stops. If the screw diameter is still large and the breaking strength is high, tightening with the stopper has the disadvantage of causing damage to the bit of the tool, the clutch of the electric rotating tool, and other transmission mechanisms.

The present invention has been made in view of the current situation, and the other tightening of the electric rotary tool is only done by attaching it to the tool, and the stopper of the drill bit is set according to the peak height of the entire corrugated plate. In addition to being able to automatically tighten the flat washers and gaskets attached to the drill screws and other fasteners to the position shown in FIG. The object of the present invention is to provide a corrugated board construction device that can be carried out extremely easily and quickly without requiring any manual work.

In order to achieve the above object, the corrugated board construction device according to the present invention has an outer cylinder having legs at the F end that spans the convex strips of the corrugated board and abuts against the grooved strips on both sides, and an arcuate plate construction device at the lower end. an inner cylinder having a curved surface of A bit holder fitted to the upper part of the inner cylinder, a tightening tool bit held by the bit holder so that it can only rotate freely, and a magnet installed at the tip of the bit. holding means configured to suction and hold the head of the stopper on the tip of the bit; the stopper has a flat washer and a packing attached to its shaft, and tightening with the bit sometimes The present invention is characterized in that the tightening height is regulated by the lowest position of the inner cylinder, and the flat washer and packing are curved by the curved surface of the inner cylinder.
