Description

[0001] The present invention relates to an anchor bolt lock device,

More particularly, the present invention relates to an anchor bolt locking device for gang-foam, more specifically, a safety cover for opening and closing an anchor bolt of a gang form is simple, but structural rigidity is maintained so that opening and closing of the safety cover can be stably performed for a long period of time The present invention relates to an anchor bolt lock device of a gang-shaped type capable of stably performing opening and closing of a safety cover.

The gang form is mainly used for the installation and dismantling of exterior wall formwork and formwork and the cage for plastering and plastering work in a flat top / It is a form.

The gangbang is used for constructing the outer wall of the entire building, and the gangbang is a large structure having a weight of about 3 to 4 tons and a height of about 9 m.

This type of gangway is pulled up to the upper layer by using a tower crane. After the tower crane hook is attached to the gangway hoisting ring, the anchor bolt is dismantled and the gangway is pulled up and fixed with anchor bolt again. The process of constructing the outer wall is repeated.

At this time, the gang form is composed of an iron plate surface and a vertical member vertically installed on the outer side of the iron plate surface, and a lifting ring protrudes above the vertical member.

At this time, the lifting hook is normally formed in an inverted U-shape, and a safety hook is provided on the surface of the gang. The anchor bolt is closed by the operation of the safety hook and connected to the crane. Before lifting the anchor bolt, A safety device is installed so that it can not be used. An example of this is proposed in Korean Utility Model Registration No. 20-0470106. The anchor bolt locking device includes a vertical member vertically installed on a front surface of a gang form, a lift ring fixed to the vertical member to protrude from the upper surface of the gang form, and an anchor bolt for fixing the gang form A safety cover cradle fixed to the front surface of the vertical member and projecting forward of the vertical member; A safety cover hinged to the front surface of the safety cover cradle, the top edge of the safety cover being hinged to the front surface of the safety cover cradle, the safety cover closing the left and right side surfaces and the front and bottom surfaces of the anchor bolt, A first pulling member hinged to an upper portion of a front surface of the safety cover and extending in a vertical direction; A second pulling member whose front end engages with an upper end of the first pulling member and extends in a longitudinal direction; And a safety hook part whose lower end engages with the rear end of the second pulling member and is movable in the vertical direction from the front side of the lifting loop. Further, when the shackle for connecting the crane is connected to the safety claw part and lifts up the safety claw part, the first and second pull members are raised and the front surface of the safety cover is rotated upward so that the anchor bolt can be accessed Do.

The anchor bolt locking device has a structure in which the lower end portion of the first pulling member is hinged to the upper portion of the front surface of the safety cover to extend vertically in the vertical direction and the front end portion of the second pulling member is engaged with the upper end portion of the first pulling member, The safety collar has a structure in which the lower end of the safety collar engages with the rear end of the second pulling member and is movable in the vertical direction from the front side of the lifting collar. In order to control opening and closing of the safety cover, the safety collar and the first and second pulling members When the safety cover is raised and lowered, the coupling portion between the safety claw portion and the first pulling member, and the coupling portion between the first pulling member and the second pulling member are structurally weak, and the structure is complicated There are many problems in combining the safety collar and the first and second pulling members.

Further, the anchor bolt locking device has a structure in which the upper edge of the safety cover is hinged to the front surface of the safety cover cradle. When the first pulling cradle rises, the safety cover rotates about the hinge of the front surface of the safety cover cradle, 1 The lower end of the pulling member is hinged to the upper part of the front surface of the safety cover, so that the first pulling member is forced to ascend and descend in a constant trajectory during the rotation of the safety cover. This also causes the joint between the safety collar and the first pulling member and the joint between the first pulling member and the second pulling member to become fragile.

Accordingly, in order to solve the problems of the conventional gang-shaped anchor bolt locking device, the present invention has a simple structure of a safety cover for opening and closing an anchor bolt of a gang form, while maintaining a structural rigidity, It is an object of the present invention to provide an anchor bolt lock of a gangue which can be carried out.
