[Problems to be Solved by the Invention] However, regarding the above-mentioned frame scaffolding, the workability of assembling the building frame at high places is low,
There is a problem that it is difficult to smoothly perform the assembly work. That is, when assembling a multi-stage frame scaffold, the assembling of the building frames at each stage is done by raising the scaffold at the lower stage. Since it has to be put in, the worker moves to the edge of the lower scaffold to work. Since the lower scaffold is a high place and there is no enclosure, the operator feels a psychological pressure. As a result, workers are likely to wander and it is difficult to assemble the building frame smoothly. Especially, the building frame weighs 14 to 20K.
Even in the case of g, it is relatively heavy to continuously perform work at high places, the operator is easily tired, and the work efficiency is further reduced.

When assembling the scaffolds on the upper floors, scaffold members such as a building frame are transported by using a building or a stairway between the already assembled scaffolds. The building frame is a torii type stairway space. Since it is larger than, it is difficult to carry it without hitting the walls and scaffolds of buildings.

The frame scaffolding is disassembled and stored after use, but the building frame is a torii type in which a pair of building frame columns are connected and fixed by a horizontal cross, and a large storage space is required, so inventory control is performed. Has become difficult. Also, although multiple types of building frames with different width dimensions are used depending on the installation location of the frame scaffolding,
A large storage space is required to keep these items available at all times, making inventory management even more difficult.

The present invention has been made to solve the above-mentioned conventional problems, and its problem is to construct a frame scaffold for smoothly carrying out assembly work, transportation work and inventory control at a high place. To provide a frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The building frame 1 shown in the figure is a torii type, and has a structure in which a pair of building frame pillars 2 and horizontal rails 3 can be assembled and disassembled.

As shown in FIG. 2, each building frame pillar 2 is provided with a building frame pillar body 2a made of a tubular body such as a steel pipe, and a building frame sleeve material 2b for reinforcement is integrated with this building frame pillar body 2a. It is provided in.
An auxiliary pin receiving portion 2c into which an auxiliary pin 3c of a horizontal rail to be described later is inserted is provided on the upper side of the building frame sleeve member 2b.

As shown in FIG. 3, the horizontal rail 3 is provided with a horizontal rail main body 3a made of a tubular body such as a steel pipe, and connecting pins 3b for inserting into the building frame main body 2a are provided at both ends of the horizontal rail main body 3a. It is provided so as to project vertically, and each connecting pin 3b is attached to each building frame pillar main body 2
Each building frame pillar 2 is integrally connected by being inserted in the upper end side of a. Further, an auxiliary pin 3c is provided at a position corresponding to the auxiliary pin receiving portion 2c of the building frame pillar in the middle portion of the horizontal rail main body 3a. The auxiliary pin 3c is shorter than the connecting pin 3b, and when the building frame columns 2 are connected by the horizontal rails 3, immediately after the connecting pin 3b engages with each building frame column body 2a, the auxiliary pin receiving portion. 2c is engaged. In addition,
The auxiliary pin 3c is preferably adapted to engage with the auxiliary pin receiving portion 2c at a time different from the time when the connecting pin 3b and the building frame main body 2a are engaged, and may be longer than the connecting pin 3b. .

The building frame 1 of this embodiment is constructed as described above, and one example of the work of assembling the building frame when assembling the frame scaffold will be described with reference to FIG.

In FIG. 4, the scaffold 4 in the lower stage shows each building frame 1 in the same manner as the conventional one shown in FIG. 5, after connecting the building frame columns 2 of the pair of left and right building frames with the horizontal crosspieces 3. It is assembled by connecting with a braces to form a frame, and a scaffolding plate (not shown) is hung over the horizontal rail 3 of each building frame. The upper scaffold 5 is compact and relatively lightweight because the height of the building frame columns 2 is almost the same as the upper back of an ordinary worker, and therefore the scaffolding board of the lower scaffolding 4 is hung before the scaffolding plates are bridged. 2 is lifted and connected to the lower building frame 1. Then, after going up to the scaffolding 4 on the lower stage and connecting the building frame columns 2 of the left and right building frames with the braces (not shown) to form a frame, the upper horizontal rail 3 is lifted and moved in the direction of the arrow A, and the connecting pin 3
b and the auxiliary pin 3c are inserted and assembled in the building frame pillar main body 2a and the auxiliary pin receiving portion 2c, respectively. At that time, the auxiliary pin 3c is shorter than the connecting pin 3b, and the connecting pin 3b engages with the auxiliary pin receiving portion 2c after engaging with the building frame main body 2a. 2a can be smoothly engaged. Further, by inserting the auxiliary pin 3c into the auxiliary pin receiving portion 2c, the building frame sleeve material 2b of each building frame column is located in the same plane, and the respective building frame columns 2 are firmly connected.

When assembling the scaffolding on the upper floor,
After framing the scaffold 5 on the upper stage, lift each building frame pillar 2 to B
It moves in the direction of the arrow and is inserted into the connecting pin 3b. After that, in the same manner as above, the horizontal frame 3 connects the respective building frame columns 2. In addition, after inserting the building frame pillar 2 of each step into the connecting pin 3b, it is connected to the lower building frame pillar 2 by an arm lock (not shown).

As described above, the assembling work of the building frame 1 of each stage of scaffolding is performed while being surrounded by the pre-framed lower stage scaffolding 4 or the assembled building frame column 2 and each member. Since 2 and 3 are compact and lightweight and easy to handle, the feeling of pressure from a high place can be reduced and the operation can be performed efficiently.
Further, the disassembling work can be performed as efficiently as the assembling work by performing the disassembling work in the reverse order of the assembling work.

After disassembling the scaffold, the members 2 and 3 are transported to and stored in a storage location. The building frame 1 is disassembled into a pair of building frame columns 2 and horizontal rails 3, and each member is Since 2 and 3 are compact and lightweight, they can be stored neatly without requiring a large storage space. Therefore, the transportation work to the storage location and the inventory control can be smoothly performed.

Further, since the width of the building frame can be variously changed only by using the horizontal rails having different lengths,
Even when storing multiple types of building frames with different widths depending on the installation location of the frame scaffold, a wide storage space is not required,
It is possible to smoothly manage the inventory of building frames.

In this embodiment, the auxiliary pin receiving portion is provided on the side of the building frame sleeve material. However, the building frame sleeve material is formed of a tubular body, and its upper end side is the same as the building frame pillar body. The sleeve material for the building frame may also be used by being opened.
