Description

TECHNICAL FIELD The present invention relates to a vertical support for attaching a baseboard provided on the side of a scaffold board, and a temporary scaffolding system using the vertical support. and a temporary scaffolding system using the same.

In recent years, in temporary scaffolding at construction sites and civil engineering sites, in order to prevent accidents such as workers falling from scaffolding boards and tools falling, A skirting board is arranged on the outside of the scaffold board on the opposite side, and many proposals regarding this skirting board have been made.
For example, Patent Literature 1 discloses a baseboard fixing bracket, which is a clip for fixing a baseboard to a scaffold board. However, since the baseboard is basically configured to be locked to the protrusion at the tip of the support, it is likely to fall off due to impact or vibration.
Further, the skirting board for scaffolding disclosed in Patent Document 2 is fixed by a fixed arm to the vertical support and fixed to the horizontal member by a fixed arm. Since it is also fixed by pressing, there is also a problem that it is likely to fall off due to impact or vibration because it is a locking structure.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a vertical support for temporary scaffolding capable of firmly and easily fixing baseboards arranged on the side surface of a scaffold board at a construction site or the like to the vertical support; It is intended to provide a temporary scaffolding system using it.

In order to solve the above-mentioned problems, the present invention provides a vertical pillar, which is a vertical pipe in a temporary scaffold, in which a horizontal scaffolding pipe is attached to the vertical pillar by a pipe mounting bracket, a scaffolding plate is attached to the horizontal scaffolding pipe, and the scaffolding is provided. A vertical strut provided with a baseboard on the side surface of a plate, wherein a baseboard mounting bracket for mounting a baseboard bar is fixed to the upper part near the piping mounting bracket, and the baseboard mounting bracket surrounds the vertical strut. Four T-shaped fitting holes are provided at equal intervals, and the T-shaped fitting holes consist of a short side facing the axis of the vertical support and a long side perpendicular to the short side. The baseboard is fixed by inserting a long baseboard locking piece provided at the end of the baseboard into the hole, and the baseboard can be attached to each of the four fitting holes from any of the three directions. and a temporary scaffold system for constructing a temporary scaffold by combining them.

According to the vertical pillars for temporary scaffolding of the present invention and the temporary scaffolding system for constructing a temporary scaffold by combining them, the baseboard mounting hardware is fixed to the vertical pillars in advance by welding or the like. There was no vertical support to which baseboard mounting metal fittings were fixed to the vertical support of the scaffold, and special metal fittings or clamps were used to attach the baseboard. Therefore, it took a long time to work, and there was a danger that the metal fittings and clamps would fall off. On the other hand, in the present invention, since the baseboard mounting hardware is already fixed to the vertical support, the time required for the baseboard mounting work can be shortened, and there is no risk of the worker or tool falling. Furthermore, the mounting work can be done easily without worrying about the positional relationship. In addition, since the baseboard is incorporated into the fitting hole of the baseboard mounting bracket which is firmly fixed in advance by welding or the like, the baseboard is not detached from the vertical support and is safe. Before assembling the temporary scaffolding on site, it can be attached by a simple operation of inserting the baseboard locking piece on the side of the baseboard into the fitting hole.

A preferred embodiment of the vertical support for temporary scaffolding of the present invention and a temporary scaffolding system using the same will be described below with reference to the drawings.
First, as shown in FIG. 1, the temporary scaffolding according to the embodiment of the present invention is constructed by fixing a pipe fitting 6 and a baseboard fitting 7 to a vertical post 1 by welding or the like. As with the conventional temporary scaffolding, the pipe fittings 6 are fixed to the vertical pillars 1 through the connection devices 21 by the horizontal scaffolding pipes 2, but in the embodiment of the present invention, the skirting board fittings 7 are further fixed. One of the features is that

FIG. 2 is a diagram of a system in which a temporary scaffolding is constructed by combining the vertical struts of the present invention. FIG. Supports 1 are formed, scaffolding boards 4 are strung over horizontal scaffolding pipes 2 every 1800 mm by appropriately combining them to form a passage, and a handrail part 3 is attached to both sides of the passage formed by the scaffolding boards 4 or a building. A skirting board 5 is incorporated on the outside of the . Reference numeral 11 in FIG. 2 denotes a joint, and as shown in FIG. 2(b), it is possible to form a vertical strut having a desired height by joining the joints at the joint 11 as appropriate.
A feature of the temporary scaffolding system of the present invention is that baseboard mounting brackets 7, which can be attached to baseboards in multiple directions, are installed in appropriate places about 8 cm (5 to 25 cm) above pipe mounting brackets 6 of conventional vertical posts 1. One of the features is that they are fixed in advance by welding or the like.

[Connection device 21 for horizontal scaffold pipe 2]
Therefore, as shown in FIGS. 2(a) and 2(b), the pipe mounting bracket 6 and the baseboard mounting bracket 7 are pre-arranged so as to correspond to each other. Here, as shown in FIG. 3, the pipe mounting bracket 6 is fixed to the vertical support 1 by driving a fixing key 211 through the connection device 21, and the horizontal scaffolding pipe 2 is assembled to the pipe mounting bracket 6. A scaffolding board 4 is attached to a horizontal scaffolding pipe 2. - 特許庁
At this time, it should be noted that the fixing key 211 to be driven into the connection device 21 needs to be positioned slightly away from the outer circumference of the pipe of the vertical support 1, and it is necessary to select such a type of connection device. This is because the baseboard mounting bracket 7 is arranged slightly above the pipe mounting bracket 6 in the present invention, so that the fixing key 211 is placed in close contact with the outer periphery of the pipe as in the conventional case. This is because it interferes with the driving operation of 211.
Although the connection device 21 shown in FIG. 3 is used in this embodiment, this connection device 21 will be described in more detail with reference to FIGS.
FIG. 4 is a perspective view of the pipe fitting 6 before the connection fitting 2 is assembled. For this purpose, as shown in FIG.
When assembling, as shown in FIGS. 5, 6, and 7, first, the tooth-shaped fitting portion 213 provided at the tip of the connection device 21 is fitted into the fitting hole 61 of the pipe fitting 6 ( Figure 6). Next, in order to fix this fitted state, the movable member 212 moves toward the pipe outer circumference 12 along the oblique surface 215 and the long hole 216 of the movable member 212 by driving the fixed key 211 . , the connecting device 21 and the horizontal scaffolding pipe 2 are firmly fixed to the vertical support 1 by the extruding portion 214 at the end of the movable member 212 on the pipe outer circumference 12 side protruding from the main body of the connecting device 21 . A leaf spring 218 provided on the fixing pin 217 in FIGS. 5 and 6 pushes the movable member inward when the connecting device 21 is removed from the temporary scaffolding.

[Baseboard 5]
Next, as shown in FIGS. 8 and 11, baseboards 5 are attached vertically to the necessary portions of the side surfaces of the scaffolding board for the safety of workers and the prevention of tools from falling. The tree 5 has an L-shaped cross section consisting of a vertical surface 52 and a horizontal surface 53. At both ends of the baseboard 5, baseboard locking pieces 51 are inserted into fitting holes 71 of the baseboard mounting bracket 7 and directed downward. is provided.
Here, the overall shape of the baseboard 5 is not L-shaped, and may be simply flat. Further, the baseboard locking pieces 51 may be separated from the baseboard 5 and fixed to both ends of the baseboard 5 afterward.
Also, the function of the baseboard locking piece 51 may be such that it is simply inserted into the fitting hole 71 from above downward and removed by simply pulling it upward, or it may be easy to insert but difficult to remove. Structure, for example, an umbrella stopper structure consisting of an inclined surface, a horizontal surface, and a spring, when the baseboard locking piece 51 is inserted, it moves along the slope against the spring force, and when it is removed, the horizontal surface is engaged. A stopper structure that stops at the hole 71 may be used.

[Baseboard mounting bracket 7]
The baseboard mounting hardware 7 for mounting the above-described baseboard to the vertical support 1 will be described with reference to FIGS. 9 and 10. FIG.
As shown in FIGS. 9 and 10, the baseboard mounting bracket 7 is provided with four fitting holes 71. The fitting holes 71 are formed so as to surround the vertical support 1 (or the vertical support hole 72). Four T-shaped fitting holes 71 are provided at equal intervals, and these fitting holes 71 are T-shaped with a short side 711 facing the axis X of the vertical support 1 and a long side 712 perpendicular thereto. Although this T-shape is a shape in which the top and bottom are compressed, this is a shape for increasing the mounting direction of the baseboard 5 from two to three.
That is, as shown in FIGS. 3 and 11, the baseboard 5 is fixed by inserting a locking piece 51 provided at the end of the baseboard into the fitting hole 71, and as shown in FIG. The baseboard locking pieces 51 of the baseboard 5 can be inserted into the respective fitting holes 71 from any of the three directions orthogonal to the left and right sides of the vertical support 1, and the fitting holes 71 of the baseboard mounting brackets 7 can be inserted. 71 are provided on the outer periphery of the vertical support 1 at equal intervals (also at intervals of 90 degrees), so that the baseboards 5 can be attached in 3 directions×4=12 directions.

[Assembled configuration]
FIG. 11 shows a temporary scaffold in which a horizontal scaffold pipe 2 is attached to the pipe mounting bracket 6 of FIG. A temporary scaffolding is completed by inserting locking pieces 51. As a whole temporary scaffolding, as shown in FIG. It is preliminarily fixed by welding or the like, and the provision of a temporary scaffolding system in which the pair of pipe fittings 6 and the baseboard mounting fittings 7 are fixed to each other makes it possible to attach the baseboards as in the past without special metal fittings, Since the baseboard mounting bracket 7 is fixed in advance instead of using a clamp, the baseboard 5 can be easily incorporated.

Since the embodiment of the present invention is configured as described above, in a temporary scaffolding system for constructing a temporary scaffold by combining vertical posts for temporary scaffolding, baseboard mounting brackets are previously welded to the vertical posts. However, there is no vertical support where baseboard mounting hardware is fixed to the vertical support of temporary scaffolding by welding, etc., and special hardware or clamps are used to attach baseboards. As a result, it took a long time to work, and there was a danger that the metal fittings and clamps would fall. In addition, it was not a simple task because it was sometimes necessary to install while looking at the positional relationship of the baseboards. In addition, since the baseboard is incorporated in the fitting hole of the baseboard mounting bracket, the baseboard does not come off from the vertical support and is safe.

In the present invention, since the metal fittings for mounting the baseboard are already fixed to the vertical support, the time for mounting the baseboard can be shortened, and there is no concern about the danger of falling workers or tools. Furthermore, the mounting work can be done easily without worrying about the positional relationship. Before assembling the temporary scaffolding, it can be attached by a simple operation of inserting the baseboard locking piece on the side of the baseboard into the fitting hole. In addition, it can be installed by a simple operation of inserting the baseboard locking piece on the side of the baseboard into the fitting hole even when it is installed outside the site.
It goes without saying that the present invention is not limited to the above embodiments as long as it does not impair the characteristics of the present invention. Any shape other than that shown in FIGS. 8 and 11 may be used as long as the tree 5 can be inserted into the fitting hole 71 of the baseboard mounting bracket 7 and fixed.
