Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical curing device for covering an opening provided in a vertical wall to ensure the safety of passersby.

[0002]

2. Description of the Related Art In a building under construction, when an opening is formed in a vertical wall such as an entrance / exit of an elevator, it is necessary to take measures to prevent a worker from falling in the opening. In view of this point, in the related art, FIGS.
As shown in Fig. 2, a long member (42) is horizontally placed above and below a protrusion provided at both ends of the opening (40), for example, a pair of separators (41) used for holding a space between concrete formwork. After erection and restraining both long materials (42) with washers (43),
A nut (44) screwed to the end of the separator (41) is tightened to press the long member (42) against the vertical wall (45) to construct a fall prevention fence.

In addition to this, as shown in FIG. 6, a long member (50)
In some cases, a fall prevention fence in which U-shaped fixtures (51) are detachably attached to both ends is used. this is,
With the long member (50) removed, fix both fixtures (51) to both side walls (45) of the opening (40) with bolts (52), etc., and then fix them between both fixtures (51). Long material of appropriate length (5
0) is erected to construct a fall prevention fence.

[0004]

However, since any of the fall-prevention fences uses a long material of a fixed size, the width cannot be changed. Therefore, it is necessary to use another fall prevention fence having different lengths of the long material for the openings having different widths. Therefore, the operator has to make various kinds of fences in advance and store them, and appropriately select one that fits the width of the opening, which is inconvenient to handle. Particularly in the fence shown in FIG. 6, if the wall thickness changes, the opening width (s) of the fixing tool (51) needs to be changed accordingly, so that not only the long member (50) but also the fixing tool (51). It is necessary to prepare a large number of types, and the above-mentioned harmful effects appear more remarkably.

Further, in the structure shown in FIGS. 5A to 5C, the nut (44) needs to be tightened, whereas in the structure shown in FIG. 6, the bolt (52) needs to be tightened.
When constructing fall prevention fences in a large number of openings, the on-site assembly labor becomes excessive.

[0006] Therefore, an object of the present invention is to provide a vertical curing device which can handle openings of any width and wall thickness with a single device and can be attached by a simple operation.

[0007]

In order to achieve the above object, the device of the present invention is a device for curing an opening provided in a vertical wall, and is a fixed frame and a movable frame supported by the fixed frame. It is provided on the frame and the fixed frame, and the movable frame opens the opening.

The fixed side locking device and the movable side locking device are formed by stacking the base end portions of a pair of L-shaped holding members and abutting each other in a U-shape. Allowing the approaching / separating movements of both locking devices in the overlapping part,
A fixing means for fixing both locking tools at an arbitrary position is provided.

Positioning means for positioning the movable frame slid to a predetermined position with respect to the fixed frame may be provided.

[0010]

With the above construction, since the guide portion slides and guides the movable frame in the direction of opening and closing the opening, the width of the device can be varied. Therefore, it can be attached to an opening of any width.

Further, the fixed side locking tool and the movable side locking tool are
The base ends of a pair of L-shaped holding members are overlapped with each other and abutted against each other in a U shape, and the overlapping parts of both locking members allow the approaching and separating motions of both locking members. In addition, if the fixing means for fixing the both at an arbitrary position is provided, it is possible to adjust the opening width of both the locking tools to an arbitrary width and hold the opening width.

When the movable frame is slid to hold the vertical wall by both locking members and then the movable frame is positioned by the positioning means, both locking members will not be disengaged from the held vertical wall.
Therefore, it is not necessary to fix the locking tool to the vertical wall with a bolt or the like after installation in the opening.
