Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 This invention relates to a fall-prevention frame used when performing construction on the roof of a building.

[0002]

[Prior art]

 When constructing a new building or on a roof for renovation, for example, when building a roof or roofing tiles, build a temporary scaffold around the building and use this temporary scaffold to climb up and down the roof and raise and lower materials. I am trying to do.

[0003]

[Problems to be solved by the device]

 By the way, since the temporary scaffolding is installed with a predetermined space between it and the tip of the roof, there is a gap between the tip of the roof and the temporary scaffolding, and materials on the roof drop from this gap, There is a problem that an accident occurs in which the worker falls.

Therefore, an object of this invention is to be able to close a gap formed between the tip of the roof and the temporary scaffolding, and reliably prevent a material from dropping from the gap and a fall accident of an operator. The purpose is to provide a fall prevention frame for roof construction.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the device of claim 1 connects two closing members with a hinge so that the angle can be changed, and one side edge of the closing member holds a lateral pipe of a temporary scaffolding. It adopts a configuration with a lock.

According to a second aspect of the present invention, the closing member is formed by stretching a mesh on a rectangular frame body, and the two closing members are configured such that the frame bodies are connected to each other by a hinge.

Here, for the hinge, the hinge plates fixed to the respective frame bodies are overlapped, and the overlapping portions of both plates are joined with bolts and nylon nuts in a half-tightened state, so that the angles of both blocking members can be freely set. At the same time, it has a structure that holds the angle setting state.

[0008]

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described with reference to the illustrated examples.

As shown in FIGS. 1 and 2, the temporary scaffolds 2 provided around the building 1 are arranged so as to form a predetermined space with the tip of the roof 3, and the temporary scaffolds 2 have a constant space. It is constructed by a combination of a vertical pillar 4 standing upright and a horizontal pipe 5 fixed to the vertical pillar 4 at appropriate intervals in the vertical direction. Above the temporary scaffold 2, the circumference of the roof 3 and the temporary scaffold 2 are formed. A fall-prevention frame 6 for closing a gap created between is detachably attached.

As shown in FIGS. 3 and 4, the fall prevention frame 6 has two closing members 7 and 8 connected by a plurality of hinges 9 so as to be variable in angle, and one side edge of the closing member 7 It has a structure in which a plurality of hooks 10 are provided.

The closing members 7 and 8 are formed by arranging a metal mesh 12 on a rectangular frame body 11 made of an angle material or the like and reinforcing the frame body 11 with a reinforcement 13 using a flat bar. The closing members 7 and 8 are connected to each other by a frame 9 and a hinge 9.

As shown in FIG. 3 (C), the hinge 9 has two hinge plates 14 and 15 welded to each other's frame bodies 11 and 11 overlapped with each other, and the overlapped portion with a bolt 16 It is formed by fixing it in a half-tightened state with a nylon nut 17, and fixing a stopper 18 to the rear edge of one hinge plate 15.

Both of the closing members 7 and 8 can be unfolded from the two-folded state in which they are overlapped with each other by the connection with the hinge 9, and the two-folded state and the unfolded state of the desired angle can be obtained by the joint tightening force of the hinge 9. It is designed to be held and the angle can be changed manually.

The horizontal lengths of the closing members 7 and 8 may be set according to the intervals between the vertical columns 4 of the temporary scaffold 2, and if a plurality of different lengths are prepared, the site is prepared. It is possible to meet the conditions of.

The fall prevention frame of the present invention has the above-mentioned structure, and is located above the tip of the roof 3 above the temporary scaffold 2 provided around the building 1, as shown in FIGS. 1 and 2. The fall prevention frame 6 which is folded in half is attached to the horizontal pipe 5 in a hanging shape by locking the hook 10 so that the roof 3 is surrounded.

In this state, the other closing member 8 is pushed down against the one closing member 7 hung on the horizontal pipe 5, the hinge 9 is tilted toward the roof 3 side as a fulcrum, and the tip thereof is brought into contact with the roof 3. For example, by means of one closing member 7 suspended on the lateral pipe 5 and the other closing member 8 located between the lower end of this closing member 7 and the upper surface of the roof 3, the space between the tip of the roof 3 and the temporary scaffold 2 It is possible to close the gap generated in the.

As a result, the fall prevention frame 6 can prevent accidents in which the material falls from the roof 3 or the worker falls.

In addition, when raising or lowering a material on the roof 3 or raising or lowering a worker, the other closing member 8 is pushed up so that both closing members 7 and 8 are folded in two, and the tip of the roof 3 and the temporary scaffolding 2 are formed. Open the gap.

[0019]

[Effect of device]

 As described above, according to the present invention, the gap formed between the tip of the roof and the temporary scaffold can be closed by simply attaching it to the upper horizontal pipe of the temporary scaffold in a suspended manner, and the material from the rooftop can be closed. It is possible to reliably prevent the fall of the building and the accident of the fall of the worker, and improve the safety of the work on the roof of the new construction and the reform.

Further, since the two closing members are connected to each other at variable angles, if they are folded in half while suspended on the temporary scaffolding, the gap between the tip of the roof and the temporary scaffolding is opened, and the material is raised and lowered. There is no hindrance to the lifting of workers and workers.
