Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a framework scaffold used at construction sites, etc., and particularly relates to a scaffolding device erected outside a building frame.

[Prior Art] As is well known, at construction and demolition sites of buildings, etc., it is customary to erect scaffolding and span scaffolding boards along the outside of the building, and to perform work thereon. Between the scaffolding and the building, frame pillars 1 and brackets 2 of the building frame are fixed as shown in Figure 6 to prevent workers from falling and to work on building walls, etc., and plywood or Scaffolding boards 3 made of steel plates are stretched across the building.

[Problems to be solved by the invention] The conventional scaffolding device described above has the following problems, and improvements are desired.

That is, in structures such as buildings, it is necessary to assemble and install formwork 4 in order to cast concrete for external walls, etc., and to remove and dismantle the formwork after completion of the external wall construction. Therefore, if the brackets are fixed in accordance with the workability during assembly and installation or dismantling of the formwork, when the formwork is removed, that is, during finishing, the distance between the scaffolding board and the building (opening size) is too large and the building will fall. There is a risk of this, and furthermore, it will hinder the finishing work.

On the other hand, if the opening size is narrowed to ensure workability during finishing and to prevent falls, it becomes very difficult to install and remove the formwork, and as a result, as shown in Figure 7, the bracket 5 must be moved diagonally. and install it,
Since the scaffolding boards 6 had to be hung and the scaffolding boards had to be removed in areas where there would be gaps, there was a serious safety problem.

[Means for Solving the Problems] The present invention was made in order to eliminate the problems of the conventional scaffolding board device. A scaffold board device comprising a scaffold board support bracket fixed horizontally and a two-ply expandable scaffold board installed between each of the support brackets, the scaffold board support bracket comprising: A horizontal member for hanging a scaffold board, a vertical member vertically connected to the inside of the horizontal member, a pipe clamp attached outwardly to the upper end of the vertical member, and a circle attached outwardly to the lower end of the vertical member. It consists of an arcuate receiving part and a reinforcing member that diagonally connects the inside of the lower end of the vertical member and the inside of the outer end of the horizontal member, and the horizontal member is inserted into the outer cylinder and the outer cylinder so as to be freely retractable, The scaffold board has an inner cylinder formed with a stopper to prevent the scaffold board from coming off at the outer end, and the scaffold board has a pair of rectangular scaffold board units made of steel, and the long sides of the pair are foldably connected by a hinge. Hook-shaped locking pieces are fixed to both sides of the scaffold board unit near the front and rear ends.

[Example] Hereinafter, the scaffold board device of the present invention will be specifically described based on the illustrated example.

Figures 1 to 5 show an embodiment of the scaffold board device of the present invention, in which a scaffold board support bracket is installed near the upper end of one of the frame pillars 11 constituting each frame 10 of the assembled framework scaffold. 12 is attached so as to be horizontal with the frame pillar 11, and a foldable scaffold board 13 is constructed on the upper surface thereof.

The scaffold board supporting bracket 12 is
3, and a vertical member 15 connected vertically to the inner end of the cylindrical horizontal member 15.
, a pipe clamp 16 attached to the upper end of the vertical member 15 facing outward, and an arcuate receiving part 1 attached to the lower end of the vertical member facing outward.
7, and a reinforcing member 18 obliquely attached between the inner lower end of the vertical member 15 and the inner outer end of the horizontal member. The horizontal member 14 is made up of an outer cylinder 14a and an inner cylinder 14b inserted into the outer cylinder so as to be able to move forward and backward.A stopper 19 for preventing the scaffold board 13 from coming off is attached to the outer end of the inner cylinder 14b. There is.

On the other hand, as shown in FIGS. 1 to 2B, the scaffold board 13 has hook-shaped locking pieces 20 near the front and rear ends on both sides.
A pair of scaffolding units 13a, 1 to which 21 is fixed
3b are foldably connected by hinges 22, 22. Each of the scaffolding units 13a and 13b has a rectangular frame 23 made of channel material, and a top plate 2 made of a steel plate with a non-slip surface.
At the same time, a bottom plate 25 made of a steel plate with a non-slip surface is similarly fixed to the bottom of one of the scaffolding board units, that is, the scaffolding board unit 13b located on the building side when the scaffolding board is expanded. are doing. In addition, the reference numeral 26 in the figure is a reinforcing plate placed inside the hinge mounting surface, and the reference numeral 27 is an arc-shaped stopper piece attached to the base of the locking piece 20, and as shown in FIG. , 28 has a locking piece 2
It is attached by inserting pins 29, 29 provided at the base of 0.

Now, to explain how to use the scaffold board device of the present invention having the above configuration, as shown in FIG. Horizontal member 1
4 are connected, and the receiving portion 17 is fitted to the frame post 11, so that the horizontal member 14 is horizontally fixed to the frame post 11.

Then, the locking piece 2 of the scaffold board 13 in the folded state
0 and 20 are placed and supported by hanging them on the horizontal member 14. Furthermore, after the formwork of the building is dismantled and removed, that is, during finishing work, the inner cylinder 14b is pulled out and fixed from the horizontal member outer cylinder 14a of the support bracket 12, as shown in FIGS. 4 and 5. , After that, the folded scaffolding board 13b is expanded and the locking pieces 21, 21 of the scaffolding unit 13b are opened.
is engaged with the inner cylinder 14b.

[Effects of the Invention] Since the scaffolding board device of the present invention has the above-described configuration, it has the following effects.

In other words, it is possible to secure the scaffolding by folding or expanding the scaffolding board according to the construction procedure of the building, and it is also possible to adjust the opening dimensions between the scaffolding and the building. This not only prevents accidents from falling between objects and objects from falling, but also ensures a safe work floor and greatly improves work efficiency.

Furthermore, the scaffold board device of the present invention can be easily installed at the time of assembling the framework scaffold, and can be said to be extremely practical.
