In a conventional temporary frame scaffold, for example, a torii-type or gate-type building frame is juxtaposed at a predetermined interval, and these opposing building frames are crossed in a scaffolding plate and an X shape at the upper and lower ends thereof. Are connected to each other, and a similar building frame is added upward using a joint on the upper side, and assembled at a desired height.
[0003]
However, a large space is created between the brace connected to such a building frame and the scaffolding plate attached to connect the upper end or the lower end of the building frame. When a worker who works in the carelessly steps out of the scaffolding board, there is a risk of falling down from the space together with the body.
[0004]
On the other hand, a temporary frame scaffolding provided with handrails between upper end portions and lower end portions of opposing building frames, or between upper end portions and lower end portions of each brace connected to the building frame is disclosed in, for example, -107518. According to this, it is said that the installation of the handrail can prevent the worker from falling from the scaffolding board.
[0005]
[Problems to be solved by the invention]
However, even in such a conventional temporary framework scaffold, the handrail is not high enough to be easily grasped by the hand on the scaffold plate, in other words, near the middle of the brace, so it can be used as a substantial handrail. There was a problem that it was difficult. In addition, such a handrail has a problem in that it is troublesome to attach or detach it to a building frame or a brace when assembling or disassembling a temporary frame scaffold, and in particular, it causes a significant decrease in scaffold assembly efficiency. .
[0006]
The present invention solves the above-mentioned problem, and the handrail can be arranged at an intermediate height that can be easily grasped by a worker on the scaffolding plate, and the space between the brace and the scaffolding plate and both sides of the bracelet An object of the present invention is to provide a brace device with a handrail that can reduce the space and can be easily and quickly stored, transported, and mounted on a temporary frame scaffold by assembling the handrail together with the brace so that it can be folded. .
[0007]
[Means for Solving the Problems]
In order to achieve the above object, one means of the present invention comprises two pairs of braces, at least one handrail, and a bracket provided in the middle of the handrail, and each brace has an intermediate between each brace. In the brace apparatus that is pivotally supported at the crossing position, the bracket is composed of a support piece coupled in a direction perpendicular to the handrail and a plate-like stop piece provided in a horizontal direction from the support piece. Is inserted above the crossing position of each brace, and the support piece is pivotally supported at the crossing position of the pair of breaths.

In this case, a holding piece facing the support piece is provided at the end of the stop piece, the two pieces are held by the support piece and the holding piece, and the support piece, the two breaths and the holding piece are pivotally supported. It is preferable.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
As shown in FIG. 1, the basic structure of the breathing apparatus of the present invention comprises two pairs of breaths 1, 2, at least one handrail 5, and a bracket 6 provided in the middle of the handrail 5. 2, a bracket 6 is rotatably supported at an intermediate crossing position between the braces 1 and 2. As shown in FIGS. 3 and 4, the bracket 6 is composed of a support piece 6A and a plate-like stop piece 6B continuously provided in the horizontal direction from the support piece 6A. The support piece 6A is pivotally supported via the shaft 3 at the intersecting position of the pair of braces 1 and 2 by being inserted above the intersecting position.
[0011]
In this case, the support piece 6A is coupled in a direction perpendicular to the handrail 5, that is, vertically.
Further, as shown in FIG. 4, a holding piece 6C facing the support piece 6A is provided at the end of the stop piece 6B, and the two pieces 1 and 2 are held between the support piece 6A and the holding piece 6C, and the support piece 6A. The two braces 1, 2 and the holding piece 6C are pivotally supported together by the shaft 3.
However, it can be used without the holding piece 6C.
[0012]
The details will be described below.
[0013]
1 and 2 are a front view and a plan view showing a brace apparatus with a handrail according to the present invention, in which two breaths 1 and 2 are pivotally supported by a support shaft 3 at an intersecting position. Both ends of these braces 1 and 2 are detachably connected to a pair of vertical members 4 and 4 constituting a building frame P of a temporary frame scaffold by a gravity lock mechanism using a gravity lock pin 4a. As this connection structure, any well-known structure in which a pin can be easily and quickly attached and locked through a hole can be employed.
[0014]
A handrail 5 is constructed between the pair of vertical members 4 and 4. A bracket 6 protrudes from the center portion of the handrail 5 so as to face upward, and this bracket 6 is pivotally supported by a support shaft 3 that supports the braces 1 and 2. Accordingly, each of the braces 1 and 2 and the handrail 5 can be rotated about a single support shaft 3 as shown in FIGS.
[0015]
The handrail 5 integrally has a substantially L-shaped bracket 5A as shown in FIGS. 1 and 2 at both ends, and is detachably coupled to the longitudinal member 4 via the bracket 5A. Yes.
[0016]
In FIG. 1, an intermediate beam 10 is installed on each of the braces 1 and 2 facing below the handrail 5. That is, the middle rail 10 is rotatably supported by the gravity lock pin 4b support shaft near one lower end portion of one of the braces 1, and the multi-end slides via a ring 12 near the lower end portion of the other brace 2. It is inserted freely.
[0017]
Further, in FIG. 5, a horizontal member 13 that connects the upper and lower vertical members 4 and 4 constituting the building frame P is installed between the upper horizontal member 13 and each vertical member. In order to prevent buckling, a reinforcing member 14 provided with a ladder-shaped cross member 14a is connected. In addition, the working scaffold board 15 is constructed by the well-known locking method to the horizontal members 13 and 13 which oppose.
[0018]
The brace apparatus with a handrail of the present invention is attached to each vertical member 4 configured as described above and constituting the building frame P. With the completion of the construction work, the brace apparatus with a handrail is constructed as follows. Removed from P body. First, the brackets 5 </ b> A at both ends of the handrail 5 are removed, and both ends of the handrail 5 are made free with respect to each vertical member 4. At this time, the handrail 5 is supported by the braces 1 and 2 while maintaining a substantially horizontal state via the support shaft 3 of the bracket 6 at the center. In this state, the braces 1 and 2 are rotated in the directions of arrows X and Y in FIG. 1 with respect to the handrail 5 so that the handrail 5 and the braces 1 and 2 are folded and overlapped. At this time, the ring 12 of the crosspiece 10 slides in the Z direction and can be stacked along the brace 1 without falling off the brace 2.
[0019]
Moreover, this brace apparatus with a handrail is expanded in X shape as shown in FIG. 1 at the time of the incorporation to a temporary frame scaffold. At this time, the handrail 5 is positioned above the scaffold plate 15 by, for example, about 90 cm, so that the operator can easily grasp the handrail 5 by hand during the work, and can perform the work safely and quickly. Can proceed.
[0020]
Further, an intermediate beam 10 is provided below each brace 1 and above the scaffold plate 15 so as to block the space between them, so that the intermediate beam 10 can contact the leg of the worker. In this case, it is possible to prevent an operator from accidentally removing his / her foot from the scaffold plate 15, thereby preventing the worker from falling through the space.
[0021]
Further, since the braces 1, 2, the handrail 5 and the middle rail 10 can be compacted by overlapping them in a rod shape, there is an advantage that they can be transported, stored and mounted on the temporary frame scaffolding easily, quickly and at low cost.
[0022]
Next, the installation process of the breathing device will be described.
[0023]
The braces 1 and 2 and the handrail 5 are initially overlapped substantially horizontally, but when they are erected on the building frames P and P, the braces 1 and 2 are rotated in the direction of the arrow Q and expanded into an X- Next, the upper and lower ends of the braces 1 and 2 are hooked on the gravity lock pins 4a of the longitudinal member 4, and then both ends of the handrail 5 are coupled to the longitudinal member 4 via the bracket 5A.
[0024]
What should be noted here is that the stopper piece 6B of the bracket 6 is inserted above the intersecting position of the braces 1 and 2, and this stopper piece 6B is formed in a plate shape. The brace 1 and 2 are in contact with each other and supported.
[0025]
For this reason, the support piece 6A always stands vertically downwards, and as a result, the handrail 5 is always arranged horizontally and prevented from hanging around and rotating. For this reason, if the braces 1 and 2 are joined to the longitudinal members 4 and 4, the handrail 5 is inevitably disposed horizontally, and the bracket 5A can be joined to the longitudinal member 4 without interfering with the transverse member 14a of the reinforcing member 14.
[0026]
If the stop piece 6B does not exist, the handrail 5 is pivoted about the support shaft 3 and hung, and when the braces 1 and 2 are joined to the vertical member 4, the handrail 5 is inclined. When this is attempted to rotate horizontally, the brackets 5A at both ends may be caught by the cross member 14a of the reinforcing member 14 and may not be horizontal. However, in the present invention, since the handrail 5 is horizontal when the braces 1 and 2 are joined as described above, it is possible to align the handrail 5 so as not to be caught by the cross member 14a.
[0027]
Further, when the braces 1 and 2 are folded and expanded in an X-shape as shown in FIG. 1 and installed on the vertical members 4 and 4, the middle rail 10 is horizontal as shown in FIG. It turns toward the direction. It should be noted here that in the present invention, the stopper piece 6B of the bracket 6 is inserted above the intersecting position of the braces 1 and 2, so that the upper portions of the braces 1 and 2 are rotated in the directions of arrows Q and Q. When expanded to the maximum position, the breaths 1 and 2 abut against both sides of the stopper piece 6B and are prevented from rotating further. For this reason, it is possible to prevent the breaths 1 and 2 from being excessively rotated, and the breaths 1 and 2 are not vertically stacked. That is, if the stop piece 6B is not provided, the breaths 1 and 2 may rotate in the direction of the arrow Q, and may be in a vertical state as a result of excessive rotation. In this case, the ring 12 of the middle rail 10 may slide down and come off. However, in the present invention, the amount of rotation of the breaths 1 and 2 is restricted by the stopper piece 6B, so that the breaths 1 and 2 do not become vertical and the ring 12 does not come out.
[0028]
【The invention's effect】
According to the invention of each claim, since the stop piece of the bracket is inserted between the braces, the stop piece is supported by the brace to hold the handrail horizontally and restrict the amount of rotation of the brace.
[0029]
As a result, when the brace device is installed on the building frame, the handrail can be coupled to a predetermined mounting position without interfering with other members while being in a horizontal state.
