Description

SEMI-AUTOMATIC TURN STILE GATE

The present invention relates to a semi-automatic rotary gate for preventing unstable opening of a rotary gate during a high-altitude operation process.

Generally, prefabricated scaffolds are used as construction materials for civil works or construction sites.

The prefabricated scaffold is connected to the plurality of scaffold bars so as to cross each other, and is installed on the outer wall of the building or the civil engineering site. Therefore, the worker can install the scaffolding on the prefabricated scaffold at the elevation work site which is considerably elevated from the ground, and can steadily carry out construction and civil works.

However, there is a problem that a safety accident that falls in a state in which the operator can not accurately recognize the access portion may occur in the process of passing through the access portion provided between the assembled scaffolds.

Accordingly, in order to prevent the worker from falling out of the entrance / exit portion, a rotation gate is provided at the entrance / exit portion provided on the prefabricated scaffold. However, since the rotation gate is freely rotatable in the inside or outside direction of the access portion, when the operator unstably opens the rotation gate, the rotation gate may fall and cause a safety accident.

1 to 3, the semiautomatic rotary gate 100 according to the first embodiment of the present invention is configured to open and close an entrance portion 13 provided between the scaffolds 11 installed at a high work position And is rotatably installed.

More specifically, the semi-automatic rotation gate 100 includes a door frame 10 formed to have a size corresponding to the size of the opening of the door 13, And a clamping part 30 fixed to the rotary hinge 20 and fixing the door frame 10 to the scaffold 11.

The access portion 13 refers to a portion provided on the outer wall of a building or the like and opened to a predetermined size between the scaffolds 11 where the elevating work proceeds. That is, the entrance portion 13 may be formed as an opening defined by the scaffolds 11 in a predetermined size. The door frame 10 can be rotatably installed on the scaffold 11 forming the entrance 13.

The door frame 10 may be formed by assembling a plurality of frame bars, or may be provided by a plate-shaped panel (not shown). In this door frame 10, a rotary hinge may be provided on the scaffold 11 so as to be rotatable in a semiautomatic manner.

The rotary hinges 20 may be provided at equal intervals along one side edge of the rotation center position of the door frame 10. The rotary hinge 20 may be provided with a spring member (not shown) therein to enable the door frame 10 to automatically return to the rotated state. That is, the door frame 10 can be automatically rotated to a position where it closes the entrance portion 13 by the elastic force of the spring member (not shown) in the state where no external force is applied.

The rotary hinge 20 is capable of rotational operation in one direction, and rotation operation in the reverse direction is restricted, which is known, and its detailed configuration and operation are omitted. The rotary hinge (20) is provided with a clamping portion (30).

FIG. 4 is a plan view schematically showing a state in which a clamp portion is provided on a rotating hinge in the semi-automatic rotation gate of FIG. 1, and FIG. 5 is a plan view schematically showing a state in which the clamp portion of FIG. 4 is opened.

As shown in Figs. 4 and 5, the clamp portion 30 refers to a portion fixed to the scaffold 11, and a part thereof is rotatably installed. Therefore, it is possible to fix the scaffold 11 in the state that the scaffold 30 is rotated and opened, and fix the scaffold 11 to the scaffold 11 using a fastening means such as a bolt (not shown).
