Description

{FORM FIXED BOLT LOCKING SYSTEM}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mold fixing bolt locking system installed in a mold so as to prevent a safety accident that may occur during a mold releasing operation in a mold for outer wall construction of a high-rise apartment or a building.

It is necessary to use a dowel fixing bolt locking system which can prevent a safety accident due to a fall that may occur during the operation of the outer wall construction of a high-rise apartment or a building.

In addition, in the conventional safety device provided at the upper end of the formwork, the square concrete washer, the wing nut, and the cedar bolts used as the form fixing bolts are locked at the lower end of the form because the initial concrete compressive strength is not exhibited, It is necessary to develop a locking system for fixing a dowel fixing bolt which can lock both the gang-fixing bolts and the sidewalls of the gantry fixing bolts.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems occurring in the prior art, and it is an object of the present invention to provide a method of constructing a plurality of rectangular washers and wing nuts, which are used as a means for fixing a work fixing bolt to a concrete outer wall, , And to provide a locking system for a dowel fixing bolt that can lock or unlock a sidewall bolt.

Further, the lock cover capable of locking or unlocking the plurality of square washers, wing nuts, and sidewalls is provided with a locking bolt lock system that can always maintain a locked state before pulling the safety hook of the form top.

It is another object of the present invention to provide a mold fixing bolt lock system capable of simultaneously operating a lock cover at an upper end portion and a lower end portion through a safety collar even if the distance from the upper end of the form to the lower end of the form becomes about 3M or more.

According to an aspect of the present invention, there is provided a dock fixing bolt locking system comprising: a base member installed adjacent to an L anchor fixing bolt; And a lock cover having an obtuse-angled cross-section that can lock or unlock the L anchor fixing bolt by pivotally coupling with the hinge; And an operation knob which can include a pulling shaft and connect the pulling shaft and the safety loop, and a safety loop which is fixed to the operation knob and is installed adjacent to the lifting loop of the gang form and the hinge, An elastic body supported by the base material to provide an elastic force to the lock cover; a guide member fixed to the lock cover bracket and the lock cover bracket; And a movable base member moving in a horizontal direction according to the guide of the guide member; And a movable base member that moves in a horizontal direction in accordance with the guide grooves and guide grooves, and the operation knob further includes a knob jaw and an operation groove.

According to the locking system for fixing the dowel fixing bolts according to the embodiment of the present invention, the dowel fixing bolt is fixed to the crane through the lock cover which locks or opens the square washer, wing nut, It is possible to prevent a safety accident caused by the fall of the form caused by disassembly in advance and to make the lock cover have an obtuse angle and to increase the rotation angle and to provide a sufficient curing period Which is fixed to the outer wall of concrete of the lower layer, and the rectangular washer, wing nut and cedar bolt fixing the formwork, it is possible to prevent the safety accident that may occur by disassembling the form fixing bolt in advance It is effective.
