Description

[Detailed Description of the Invention] The present invention relates to an opening/closing handrail for fall prevention that is attached to the end side of a framework scaffold.

Frame scaffolds are assembled at construction sites using building frames, simple frames, bracket frames, cloth boards, etc., and contribute to the ease, safety, and workability of construction work.

In order to further improve safety, frames have been installed on the gable side of frame scaffolds to prevent people from falling.

This frame generally has a configuration in which a clamp provided on the frame is secured to a horizontally short rod provided between a gusset rod that extends inwardly from the building frame and a side frame of the building frame. Met.

As a result, the frame cannot be opened or closed, and to do so requires the frame to be attached and detached each time, which requires a great deal of time and effort.

In addition, since the dimensions of the frame are fixed, it is necessary to select and manufacture the frame according to the dimensions of the building frame, which reduces work efficiency, increases the number of frame models, and increases the cost of procuring equipment. With the increase in the number of machines and the number of models, there were problems such as the need for human resources to maintain and manage the machines.

In view of the above, it is an object of the present invention to provide a frame scaffolding opening/closing handrail that can be easily attached to and removed from a building frame, can be opened and closed as appropriate, and can be expanded and contracted to a predetermined size.

An example of the present invention will be explained in detail based on the drawings.

Reference numeral 1 denotes a conventionally known so-called torii-type building frame, 2 its gusset rod, 3 and 3a lock rods provided on the inner surface of the side rods, and hook pieces 4 and 4a that can be freely retracted from the lock rods 3 and 3a. is provided.

There are also ladder-type building frames, simple frames, bracket frames, etc. in the row of torii-type building frames 1, but these have almost the same configuration as the torii-type building frames 1.

Reference numeral 5 denotes a columnar body having support pieces 7, 7a provided in a direction perpendicular to the axis thereof, each having a through hole 6° 6a to be inserted into the lock rod 3, 3a. In this embodiment, the support pieces 7, 7a are Column 5
Its base is fixed to the upper and lower ends of the pillar 5 and to the side surface of the column 5, and the upper and lower support pieces 7.7a are attached so as to be at the same position when viewed from the vertical direction.

A handrail frame 8 that can be opened and closed is hinged to the column 5.

The hinge means may be a hinge, but in this embodiment, the handrail frame 8
The short i10, 10a fixed to one side rod 8a is loosely fitted to the column 5, and the stopper fixed to the column 5 is loosely fitted to the column 5. 9
．． 9a, and is configured to suppress vertical movement of the handrail frame 8.

A telescoping handrail frame 12 is extendably provided on the other side beam 8c and horizontal beam 8b of the handrail frame 8, and can be expanded and contracted by screwing back a thumb screw 11.11a etc. screwed onto the horizontal beam 8b. is regulated.

The thumbscrews 11 and 11a are preferably provided with elongated holes 12c on the inner surface of the horizontal rod 12b of the telescoping handrail frame 12, and the thumbscrews 11
．． It is preferable to insert the tip of the handrail frame 11a to prevent the telescopic handrail frame 12 from coming off the handrail frame 8.

Reference numeral 13 denotes a locking tool attached to the extendable handrail frame 12, which is used by wrapping it around the appropriate location of the gusset rod or gusset rod 2 of the building frame 1 to fix the opening/closing handrail to the building frame 1. .

Next, to explain the usage status of this invention, first, the building frame 1
The through holes 6, 6a of the support pieces 7, 7a are inserted into the lock rods 3, 3a, and the support pieces 7 are successively inserted while pressing the hook pieces 4, 4a.
, 7a is inserted, and when it is disengaged from the hook pieces 4, 4a, the hook pieces 4.4a protrude, and the support pieces 7, 7a are fixed to the locking rods 3, 3a, so that the column 5 is attached to the building frame. Attached to 1.

Then, screw back the thumbscrews 11 and 118, extend the telescopic handrail frame 12 as shown in Figure 2, and align it with the gusset 2. Next, screw in the thumbscrews 11 and 11a, and move the telescopic handrail frame 12 to the handrail frame 8.
to be integrated into.

Next, by locking the locking tool 13 to the gusset 2, the opening on the end side of the framework scaffold is closed with the opening/closing handrail.

It can be opened by simply engaging and disengaging the locking tool 13, and the opening/closing handrail of the present invention can be easily removed by reversing the above-mentioned operation.

Furthermore, when installing it on the opposite gable side, any means may be used, such as reversing the method of the present invention or installing it in the normal state on the locking rod of the opposite side rod of the building frame 1.

As explained in detail above, the present invention involves fitting a supporting piece of a column into a lock rod, hinged to this column a handrail frame having a telescoping handrail frame so as to be able to open and close freely, and attaching the support piece to the telescopic handrail frame. Since the locking device is configured to control the above-mentioned opening and closing, it is possible to effectively prevent people on the wife's side from falling, and when the handrail frame is opened, building materials and people can freely enter and exit from the wife's side. As a result, the workability is further improved.

Moreover, since the extendable handrail frame is made to be freely extendable and retractable, as long as the dimension between the locking rods 3.degree. 3a is constant (usually, it is a specified dimension).

), it can be freely adapted to building frames of various dimensions.

This makes it possible to reduce the number of types of equipment, which is economical, and also has advantages such as ease of maintenance, management, and handling.

have an effect. Furthermore, since the telescoping handrail frame is a telescoping type, it saves on materials, has excellent strength, and has the advantage of greatly simplifying the structure.
