The strut 10 is made up of a plurality of pieces and is a basic member of this device, and the strut connecting means 20 connects the strut 10 when the strut 10 is extended.
It is inserted between 10 and 10 minutes. The brace connecting means 50 connects and reinforces the columns 10, 10 via braces 57, and forms a temporary surface together with the columns 10, 10, . The brace connecting means 80 is formed so that at least one part of one brace 57 can be bent, and in conjunction with rotatably supporting the brace 57 on the brace connecting means 50, the brace connecting means 80 reduces the distance between adjacent columns 10 and 10. One scaffold holding means 100 introduced for adjustment is for horizontally suspending the scaffold 120 on the pillar 10.

The horizontal beam attachment means 150 connects the horizontal beam 160 to the support 10°10.
The horizontal beam 160 is used to reinforce the temporary surface, maintain an arbitrary distance between the columns 10 and 10, and furthermore, the scaffold 120
This is a member used as an upper handrail.

The details of the above components will be described below.

As shown in FIG. 12, the support column 10 is made of a hollow cylindrical member made of aluminum, and has a length of, for example, 1900 mm.

Note that several types of dimensions may be used, and the dimensions can be arbitrarily selected.

A plurality of small holes 11 and large holes 12 are provided in the support column 10 along the axial direction. As shown in FIG. 13, the small holes 11 are arranged in sets of two, facing each other at 180 degrees at the same height.
This is to fix the insertion joint 14 described later.

On the other hand, as shown in FIG. 14, the large holes 12 are 9
A set of four pieces are arranged at equal intervals of 0 degrees, and are used to mount the brace connecting means 501, scaffolding holding means 100, etc., described later, so as to be immovable in the axial direction and unrotatable. Note that the support rod member 13 also has a similar configuration.

The column connector P120 has an insertion joint 14 and a column bending joint 21, and the insertion joint 14 used in this repair example has the structure shown in FIGS. 16 and 17.

In the figure, the insertion joint 14 has an insertion part 15 for insertion into the upper support 10 and an insertion part 18 for insertion into the lower support 10, and has an insertion part 15 for insertion into the upper support 10 and an insertion part 18 for insertion into the lower support 10. Tsuba 1
7 is formed. The insertion portion 15 is also provided with a pair of screw holes 16.16. The insertion portion 18 is similarly provided with a pair of screws 19°1;). screw hole 19
．． 19 is conveniently of a smaller diameter than the screw hole 16.16.

(Also, fit the upper support 10 into the insertion part 15 and tighten the two bolts of the circular spring 27 with bolts (see Figure 18(a)), and the insertion joint 14 is integrated with the upper support 10. Fixed.

Similarly, if the lower support 10 is also fixed integrally, the upper and lower supports 10
゜10 can be connected integrally.

In this case, the spring 28 of the bolted circular spring 27 is elastically fitted and held on the support column 10, so that it can be collected easily.

Such a connection state, in which there is no fear of dropping, is shown in FIGS. 18 and 19.

In addition, as shown in Fig. 15, the horizontal @160 has the same #l pattern as the support 10, and has the same insertion joint (14) as above.
A screw hole 19° 19.16 is provided for connection using a screw hole, and there is no need to provide a hole in the middle.

Next, the brace connecting means 50 is an 8-turn type, which includes a rotary type shown in FIGS. 6 and 7 and a fixed type shown in FIGS. 8 and 9, and is used when folding a temporary surface. The fixed mold is used when forming a temporary surface while keeping it in a planar shape.

In FIGS. 6 and 7, a rotary brace connecting means 5
0 consists of one member 51 and the other member 61, the one member 51 is attached to the column 10 so as not to be axially displaceable and non-rotatable, and the other member 61 is fitted onto the column 10 above. Here, the other member 61 is rotatable with respect to the support column 10, and is formed so that it can be placed in the same room at a predetermined angle.

That is, one member 51 has a small hole 53. It is formed from a cylindrical portion 52 having a large hole 54 and an ear member 55 having a hole 56, and a circular spring (27) with a bolt (not shown) is passed through the small hole 53 or the large hole 54 into the screw hole 11 or 12 of the support 10.
It is fixed to the support column 10 by fixing it to. A short member 59 of a brace (57) is rotatably connected to the hole 56 via a pin 67. , the other member 61 has a small hole 63.
Ear member 6 having a cylindrical portion 62 having a large hexagon 64 and a hole 66
Bolt 29 of circular spring 27 with bolt
through the small hole 63 or large hole 64 and screw hole 1 of the support 10.
1 or 12, it is fixed to the support column 10. Therefore, by selecting the screw hole 11 (12) of the support column 10 into which the bolt 29 is inserted, the support column 10 can be fixed at a predetermined angle in the circumferential direction. In this embodiment, the angle can be changed every 90 degrees, but the angle can be set steplessly.

Therefore, the angle of the five short members of the brace (57) rotatably connected to the ear member 65 via the pin 67 can be changed relative to the five short members connected to the ear member 55. That is, although FIG. 6 shows a connected state in which the temporary surface is a flat surface, it is possible to bend the ear member 65 of the other member 61 at a right angle to the ear member 55 of the one member 51 to bend the temporary surface at a right angle. This makes it possible. Note that the insertion openings for the braces 57 (short members 59) of the both ear members 55 and 56 are H-shaped.

On the other hand, the fixed type brace connecting means 50 shown in FIGS. 8 and 9 has one member 75 and the other member 7 connected to the cylindrical portion 71.
7 are arranged facing each other.

Both members 75.77 have holes 76.78 for inserting pins 67.67 that rotatably support the brace 57 (short member 59).
is provided. Of course, the cylindrical part 71 has columns (10
) is provided with a hole 7272 for fixing.

Now, the brace connecting means 80 is a means for making the axis of the brace itself bendable and for keeping the axis in a straight line.

Here, the brace connecting means 80 is connected to the first
As shown in FIG. 10, the brace 57 is formed from one long piece 58 and two short pieces placed on both sides of the brace 57. Two pieces (one set) are arranged on both sides. However, this brace connection means 80 may be used to connect at least one of the braces 57 as described above.
Therefore, in FIG. 1, the short member 59 on the inclined upward side and the brace connecting means 80 are omitted, and the long member 58 is directly connected to the brace connecting means 50. In this way, when one brace 57 is formed from one long piece 58 and one short piece five pieces,
One brace connection means 80 is installed in the downward direction shown in FIG.
1 set) is preferable for assembly work.

In FIGS. 2 to 4 showing the axis line holding state of the brace 57 (long material 58, short material 59), the first stage of brace connection 8
0 is composed of one member 81, the other member 91, and a locking means 85, which are rotatably supported by a shaft 94 through 180 degrees.

For example, the long member 58 of the brace is inserted into the small portion 82 of the member 81 and bolted through the bolt hole 83. The short member 59 is bolted to the small portion 92 of the other member 91 through a bolt hole 93.

Long lumber 58. Both short members 59 are made of hollow rectangular tubes as shown on the right side of FIG. The length of the elongated member 58 is approximately the same as the length of the support column 10.

The two long members 58, 58 intersect at different levels in the center and are rotationally connected by a shaft 6.

The locking means 85 also includes a locking member in which a hook 96 and an opening knob 97 are integrally provided, a spring 87 that biases the locking member, and a rivet 86 that fixes the base end of the spring 87 to the other member 91. It is formed from. The hook 96 is attached to one member 8
The release knob 9 is fitted into the hook hole 84 of 1 so as to be retractable.
7 is fitted into a hole 98 of the other member 91.

Therefore, in the illustrated axis holding state, since the hook 96 is inserted into the hook hole 84 by the biasing force of the spring 87, both members si, 9t cannot rotate about the axis 94, but the brace 57 ( The long members 58 and the short members 59) are in a straight state and can withstand the tensile force. Here, in order to bend the brace axis, the release knob 97 can be pushed in against the biasing force of the spring 87, and the hook 96 should be inserted into the hook hole 84.
move away from the inside.

As a result, the long member 58 and the short member 59, that is, the brace 57, can be bent freely around the axis 94, and the long member 58 and the short member 59 can be bent until they become parallel.

Note that the brace connecting means 80 is not limited to this disclosed structure, and may be implemented by partially modifying the disclosed structure.
For example, as shown in FIG.

It is formed from a stainless steel pin etc. driven into. Further, the rotating arm 1.05 is biased in the closing direction by a spring (not shown). Note that the locking fitting 102 is attached to the rotating arm 1.
Even if 05 is omitted, the function can be achieved by the action of the pin 104.

On the other hand, the lower end 113 of the inclined portion 111 is provided with a circular arc surface 114 circumscribing the support column 10 and a pin 115 protruding from the circular arc surface 114.

Therefore, the pin 104 of the post locking fitting 102 and the pin 115 of the inclined part 111 are connected to the holes 11<11 of the post 10, respectively.

Further, the scaffold 120 consists of a dimensionally fixed scaffold board 121 shown in FIGS. 25 and 26 and a dimensionally expandable scaffold [131] shown in FIG. 27.

The scaffolding board 121 is used when the brace 57 is in an axis-maintaining state, that is, when the distance between adjacent pillars to and lo is maximized, and the scaffolding board 131 is used when the brace 57 is in a bent state and the supporting pillar i is in a bent state.
It is used when the interval between o and io is set appropriately.

In FIG. 25, the scaffold board 121 is made of an extruded material with a plurality of perforated upright cone-shaped non-slips 122 provided on the upper surface,
A hook portion 144 consisting of a projecting portion 145° and a hook 146 is provided at both ends thereof.

Therefore, by inserting the hook 146 through the notch 107 provided in the straight portion 108 of the scaffold holding means 100 and moving it in the horizontal direction, the scaffold board 121 is placed horizontally between the adjacent scaffold holding means 1.00, 100. can do.

It is composed of a movable arm 164 and a shaft 165. However, since it has the same structure as the pillar locking fitting 102, detailed explanation will be omitted.

Note that 165 shown in FIG. 1 is a jack base.

Next, the operation of this embodiment formed including the above-mentioned structural elements will be explained together with the assembly procedure.

First, as a basic configuration, the case of assembling one temporary surface unit will be described with reference to FIGS. 1 and 10.

In this embodiment, it is assumed that one unit consisting of a pair of two pillars 10 and 10 will be successively connected in advance, and one unit will be folded as shown by the two-dot chain line on the left side of Fig. 10. ing. That is, a fixed brace connecting means 50 is fixed to each support column 10.10 of the two cars, and each brace connecting means 50 has one end of a brace 57 (5 short members) rotatably supported. There is. Therefore, in this state, each brace connecting means 80 is in a freely bendable state, and the brace 57 is stored in parallel between both supports 10 and 10.

Note that both braces 57 (elongated members 58) are connected to the brace connecting means 50 in a stepped manner, and the intermediate portions of the elongated members 58 are rotatably supported by pins 67.

Therefore, when both struts 10.10 are expanded, the braces 57 (58, 59) are in a straight line, forming one temporary surface, as shown by solid lines in FIG. In this case, each brace connecting means 80 is connected to the shaft by means of a locking means 85 (see FIG. 3). ! Selected to hold state.

Subsequently, a horizontal beam attachment means 150 is attached to each column 10.10 via a column locking part 161 (see FIG. 20). This is extremely simple since it is sufficient to insert the pin 163 into the hole 11 (12) of the support column 10.

Then, by tightening each threaded handle 157 to the horizontal beam 160 fitted into the cylindrical portion 152, the temporary surface is made even stronger as shown in FIG. Further, a scaffold holding means 100 is attached to the upper end of each support column 10. pin 10
4 into the hole 11 (12) of the support column 10, it is simple and quick.

Here, a jack base 165 is attached to the lower side of each column 10, and both columns 10 and 10 are erected.

Next, a scaffold board 121 is placed between both scaffold holding means 100, 100.
Scaffolding for the first floor will be formed by laying it horizontally.

In addition, in order to bend the next temporary surface that is connected to the right support column 10 in FIG. , a rotating type consisting of one member 51 and the other member 61 should be selected.

It should be noted that it goes without saying that the items to be attached to the support column 10, such as the brace connection means 50, may be attached to the support column 10 in advance or may be attached each time as necessary.

Here, temporary commercial supports 10, braces 57, etc., which are arranged on the left and right sides, should be connected in advance to each support 10 for one unit, which includes the part shown by the two-dot line f in Fig. 10. For example, it is understood that equipment for constructing a temporary surface of desired dimensions can be handled as a train and an integral part.

Also, both supports 10. with the brace 57 in a bendable state.
When the interval between 10 and 10 is set appropriately, the interval is the horizontal 'eJl! with respect to the horizontal beam 160. This can be done by adjusting the tightening position 'Il of the handle 14150.

Furthermore, when configuring the second floor scaffolding, as shown in FIG. Good, second floor support 10. Horizontal beam attachment means 1 also between 10
It is more preferable to provide a horizontal beam 160 via the scaffold 120. In particular, if the horizontal beam 160 is provided at a predetermined height relative to the scaffold 120, it can be used as a handrail.

Incidentally, regardless of the location conditions, the levelness of the scaffold 120 is adjusted by operating the handle of the jack base 165. As shown in FIG. 11, this second floor scaffolding can also have the same structure as the first floor scaffold shown in FIG. 10.

Until the above-mentioned temporary surface is formed, the conventional wedge-driving hammer operation and complicated operations such as screwing together a large number of bolts and nuts are not required, and the assembly can be performed quickly and accurately.

Next, FIG. 31 shows how to sequentially combine such 1-unit temporary construction surfaces to form a 4-unit, 3rd floor scaffolding.

It is sufficient to connect them as shown in Fig. 32. In this case, the 34th
As shown in the figure, in order to bend the leftmost temporary surface and the rightmost temporary surface at a right angle or at a predetermined angle, the brace connecting means is attached to the 2nd and 4th pillars 10 from the left side shown in FIG. 50 may be equipped with a rotary mold (see FIGS. 6 and 7) formed from one member 51 and the other member 61 that are relatively rotatable.

Other pillars 10, 1.0. . . may be a fixed type in which the cylindrical portion 71 is fitted and fixed (see FIGS. 8 and 9).

In order to more reliably hold the other temporary surfaces upright before bending the leftmost temporary surface and the rightmost temporary surface, as shown in FIG. Also, using a mold having a latch A of 1.02, support rod member 1 is
3 as an auxiliary arrangement, the assembly work can be made even faster.

Thus, the overall temporary construction procedure is steps A-G shown in FIG.
This can be done quickly and easily by following the steps below.

A large number of units in which a plurality of columns 10 are connected by a plurality of braces 57 are erected and expanded as shown in step A to form a temporary surface for the first floor scaffolding. In this case, the support rod member 1
3 (see Fig. 33) in some places allows for safe and reliable assembly with a small number of people.

Next, as in step B, the next temporary surface is bent around the support column 10 to which the rotating brace connection means 50 (see FIGS. 6 and 7) has been attached in advance. This allows the temporary surface to stand on its own as a whole. At this point, the support rod member 13 can also be removed.

According to step C, connect the next temporary surface unit in sequence.
Both supports 10.1 may be installed depending on work convenience and ground conditions at the erection site.
The water EF beam 160 is fixed upward and downward while adjusting the span between 0 and 0 (step D). In the case of a predetermined span, the first stage 80 of the brace connection is opened to maintain the axis.

Basically, the scaffolding holding means 100 is attached to all the supports 10 as shown in step [B].

Next step + (i) Establish the first floor scaffold by horizontally placing the scaffolding board 121 (131) as shown in F.

Next, using the insertion joint 14, a large number of units for 2 attachments are erected upward (step G), and then steps B- and -F' are repeated for the second floor.

Regarding the third floor scaffolding, steps A to F can be repeated for L of the second floor scaffolding.

As a result, as shown in FIG. 37, it is possible to form an efficient temporary scaffolding that immediately corresponds to the shape of the building.

According to this embodiment, the struts 10 and 10 are connected by the brace 57 which is formed so that the axis holding state and the axis bendable state can be selected by the brace connecting means 80. Erection of 10 degrees can be done quickly and easily, and on-site equipment transportation, assembly, and disassembly work can be significantly eliminated. In addition, the span can be adjusted appropriately, a temporary surface that fits the building dimensions can be formed without waste, and there is no accidental protrusion, so there is no danger and there is no need to worry about maintenance such as intrusion by outsiders. It is also possible to achieve the appearance and cleanliness that Totora has been particularly concerned about in recent years.

In addition, the brace 57 is a rotating brace connecting hand V150.
(51, 61), so the angle of the temporary surface sandwiching the support 10 can be set appropriately, and the entire temporary surface can stand on its own, which is particularly useful. In addition, since no gaps are created accidentally, it is possible to perform work on the scaffold smoothly and safely, in addition to improving the appearance, safety, and R mechanical strength.

Further, since the scaffold holding means 100 can be quickly and reliably attached to each support column 10 by a pin insertion method, assembly and disassembly operations can be performed quickly and easily from this point of view as well. In addition, since the scaffold holding means 100 is also provided with a locking metal fitting 102 at the rear end, the support rod member 13 can be erected parallel to the support column 10 by using this metal fitting 102, and a temporary surface at the initial stage of assembly. Able to perform standing posture reliably. Furthermore, since the scaffold 120 has a fixed scaffold board 121 and an extendable scaffold board 131, the scaffold 120 can be configured in a one-touch manner no matter how the spacing between the columns io and to is adjusted.

In addition, the structure is such that the support 10 for forming the upper M attachment can be integrally extended and erected on the top of the support 10 by the support connection means 20 using the insertion joint 14 method.
The second floor scaffolding, which is the same as the first floor scaffolding, can be easily established in a short construction period and is extremely easy to disassemble.

Further, the brace 57 allows the axis of the long member 58, which is approximately equal to the size of the support 10, and the short members 59 and 59 provided at both ends thereof to be bent through the brace connecting means 80, and to maintain the axis. Since it has a connected structure, it can be assembled in advance between the supports 10 and 10, and its bulk is low, making it convenient to transport, and a temporary surface can be immediately formed by simply expanding it at the site. Further, the brace connecting means 80 connects the long member 58 and the short member 59 so that the long member 58 and the short member 59 can be bent at an arbitrary angle of 0 to 180 degrees, and when the angle reaches 180 degrees, the locking means 85 has a lock 96. Since the art materials 58, 59 can be automatically and physically formed, the temporary surface of the unit can be established to a predetermined size and sufficient strength can be maintained. Furthermore, during disassembly, the brace 57 can be easily bent by simply pushing the release knob 97.

Further, since the brace connecting means 50 for rotatably connecting the brace 57 to the support column 10 includes a cylindrical portion with an ear member for both the rotary type and the fixed type, it can be fitted to the support column 10 in advance. 57 can be easily connected and assembled both in the factory and on site. Furthermore, the angle of the rotating type can be set by fitting the other member 61 into the hole 111.2 of the support IO, and the bending angle of the temporary surface can be quickly and easily adjusted and changed, allowing the scaffold 120 to be adjusted according to the shape of the building. It is effective in forming.

Further, since the horizontal beam attachment means 150 can be attached and detached from the support column 10 in a one-touch manner, the horizontal beam 160 can be easily installed, and the temporary surface can be reinforced regardless of the distance between the support columns 10 and 10. It can also be used as a handrail.

Furthermore, the strut connection means 20 and the brace connection means 50
, the brace connecting means 80, the scaffolding holding means 100, the horizontal beam attaching means 150, etc. are attached by inserting, fitting, inserting, etc., and there is no need for screwing bolts and nuts or driving wedges as in the past. In addition to speeding up assembly and disassembly, there is no risk of falling or financial burden due to loss.
Additionally, temporary scaffolding can be constructed without emitting noise.

Therefore, the one member 22 and the other member 32 are connected to the support shaft 37.
It is impossible to rotate around . Therefore, the upper support 10
is connected in axial alignment to the lower strut 10.

Here, if you push the handle 45 to the right in the figure against the force of the spring 48, the hook 4, which is shorter than the handle 45, will release.
4 is removed from the hole 36 inward. In this state, the one member 22 and the other member 32 are rotatable about the support shaft 37. That is, the upper strut 10 can be rotated 180 degrees so as to be parallel to the lower strut 10.

Therefore, the struts 10 constituting the first scaffolding and the struts 10 constituting the second floor scaffolding are connected by this strut bending type strut connecting means 2.
