The bracket for the scaffold is composed of an arm and a vertical member extending downward from the arm, and a brace that supports the arm and the vertical member at an angle,
A wedge fixed to the base end of the arm is inserted into and attached to the engaging frame of the support on the scaffold side. The scaffold plate mounted on this scaffold bracket had hook-shaped hooks provided at four corners, and the hooks were hooked on the arms of a pair of scaffold brackets. Since the wedge and the arm are fixed in this manner, the arm does not rotate in the scaffold bracket, and the scaffold plate is merely placed on such a scaffold bracket.

[0003]

In such a conventional scaffolding set for a building, when the scaffolding plate temporarily hinders the work after being set up, the scaffolding plate is used for the scaffolding. It was completely removed from the bracket, and the scaffold bracket itself was completely removed from the support. This is because there is a risk that a worker moving the scaffold will be obstructed if these are mounted. The work of removing and re-installing in such a case is very complicated, and it is necessary to store the removed scaffold plate and scaffold bracket separately, and the construction period is prolonged due to poor workability associated with the scaffold plate and scaffold bracket. It was also the cause.

Thus, the arm portion 12 can be rotated in the horizontal direction with respect to the fixing portion 14 about the U-shaped pin 50 and the bolt 54 as a rotation axis.

Next, a scaffold according to an embodiment of the present invention will be described. As shown in FIGS. 3A to 3C, the scaffold 60 is formed by fixing a net 64 to a rectangular frame 62. At both ends on one side (upper side in FIG. 3A) of the four corners of the frame body 62, mounting fittings 66 as first hooking means are fixed. As shown in FIGS. 4A and 4B, the mounting bracket 66 includes a side plate 67a, a front plate 67b, and a side plate 67c, and is formed in a substantially U-shaped plate as a whole. A notch groove 68 is formed in the front plate 67b. The notch groove 68 is formed in a substantially inverted L-shape, and the tip portion of the L-shape is formed in an arc shape. The width P of the notch groove 68 and the diameter Q of the tip portion are formed slightly larger than the diameter of the shaft 34. A hole 70 is formed in the side plate 67c. Hole 70
Is formed slightly larger than the diameter of the U-shaped pin 50,

Is formed in a hook shape, and a lock plate 78 is mounted on the side surface thereof via rivets 74 and 76 so as to be movable obliquely up and down.

Next, a construction scaffold set according to an embodiment of the present invention will be described. The minimum unit of the architectural scaffold set is constituted by the pair of brackets 10 and the scaffold plate 60 supported thereby. As shown in FIG. 8, the bracket 10 is mounted on a column 90. The wedge 36 is fixed by being driven into a support fitting 92 of the column 80. As shown in FIG. 2, the V-shaped bracket 40 is in contact with the peripheral surface of the column 90. The mounting bracket 66 of the scaffold 60 is hooked on the shaft 34, and the hook 72 is hooked on the end of the arm 16. At the tip of the shaft 34, a retaining portion 34a having a large diameter is provided, so that the mounting bracket 66 is not easily detached from the shaft 34. Hook 7
The second lock plate 78 attaches the scaffold plate 60 to the bracket 10.
5 is located at the lowermost end of the movable range (the state of FIG. 5) so that the hook 72 does not easily come off the arm 16. FIG. 8 shows only one side of the scaffold plate 60, but the bracket 10 and the support column 90 are installed in a pair, and the scaffold plate 60 is supported by both brackets 10. The mounting bracket 66 at the other end is similarly connected to the shaft 3
4 and the hook 72 at the other end is likewise attached to the arm 16.
Is hung on the end. A jack base and a base plate (not shown) are attached to the lower end of the support column 90.

Next, an architectural scaffold set of the present embodiment,
The operation of the scaffold bracket and the scaffold plate will be described.
The method of use when the scaffold 60 and the bracket 10 are temporarily unnecessary is performed as follows. (1) The lock plate 78 of the hook 72 is moved obliquely upward to release the lock of the hook 72 on the arm 16 of the bracket 10. (2) As shown in FIG. 7, the scaffold plate 60 is rotated upward by about 90 degrees around the shaft 34. (This state is referred to as a retracted position.) At this time, the notch groove 68 of the mounting bracket 66 is provided.
Since being formed in a substantially inverted L-shape, the shaft 34 is located in the L-shaped distal end portion (portion Q in FIG. 4 (b)), even in a state of being rotated in 90-degree upper mounting bracket 6
6 does not come off the shaft 34. (3) As shown in FIG. 6, the arm 12 of the bracket 10 is rotated toward the scaffold 60 (upward in FIG. 6).
(This state is referred to as an evacuation position.) In this state,
As shown in FIG. 10, the hole 70 of the mounting bracket 66 and the fixing piece 1
7 are polymerized with the holes 17a. (4) As shown in FIGS. 6 and 9, the lower end 53 a of the short shaft 53 is pulled out from the hole 46 by moving the U-shaped pin 50 upward, and the hole 70 of the mounting bracket 66 and the hole 1 of the fixing piece 17 are removed.
7a. In this state, the scaffold 60 and the arm 12 of the bracket 10 are fixed by the U-shaped pin 50. U
The lower end 53a of the short axis 53 of the U-shaped pin 50 is
7a, the scaffold plate 60
When the arm 12 of the bracket 10 attempts to return to the original position, a force acts to bend the lower end 53a of the short axis 53 of the U-shaped pin 50. The force acts on the lower end 53a of the short axis 53.
The scaffold 60 and the arms 12 of the brackets 10 do not return to their original positions unless they are bent and cut.
When using the scaffold plate 60 and the bracket 10 again,
The above operation is performed in reverse. 9 and 10, in order to show a fixed state, the frame 62 and the like of the scaffold plate 60 are omitted and the notch groove 68 and the hole 70 of the mounting bracket 66 are shown. In FIG. 10, the lower end 53a of the short shaft 53 of the U-shaped pin 50 is located lower than shown in the figure when fixed, but is shown higher than it actually is for the same reason.

With this configuration, the architectural scaffold set, scaffold bracket and scaffold plate of the present embodiment have the following effects. -When the scaffold 60 is temporarily unnecessary, the scaffold 6
0 is rotated upward by about 90 degrees with the shaft 34 of the bracket 10 as the center of rotation, and the arm 12 of the bracket 10 is rotated toward the support column 90. Because we can secure the moving space,
There is no need to remove the scaffold plate 60 and the bracket 10 from the support column 90 and lower it from the scaffold. Therefore, the work can be performed smoothly, and the construction period can be shortened. -When the scaffold plate 60 is temporarily unnecessary, the scaffold plate 60 is fixed to the bracket 10 only by the fixing portion 14 of the bracket 10.
Can be supported in a state where the shaft 34 is rotated upward by about 90 degrees with respect to the center of rotation.
The arm portion 12 of the bracket 10 can be turned in the horizontal direction without removing the arm portion 12 from the zero. Therefore, it is not necessary to remove both the scaffold plate 60 and the bracket 10 from the support column 90, so that the operation can be performed smoothly and the construction period can be shortened. The scaffold 60 and the arm 12 turned to the side of the support 90 can be fixed at the position by the U-shaped pin 50 so that the scaffold 60 and the arm 12 are restored to their original positions. There is no risk of returning to the position, and the safety of the worker can be ensured. The notch groove 68 of the mounting bracket 66 of the scaffold plate 60 is formed in an inverted L-shape, and when the scaffold plate 60 is rotated, the shaft 34 is located at the tip of the L-shape. Since the mounting bracket 66 does not come off the shaft 34 even after the movement, the safety of the worker can be ensured.

The present invention is not limited to the above-described embodiment, but can be embodied with the following modifications. -U-shaped pin 5 like bracket 100 shown in FIG.
Instead of 0, the rotation pin 102 and the fixed pin 104 may be connected by a chain 106. Upper part 1 of rotation pin 102
02a has a larger diameter than the hole 108 and does not fall downward. -As shown in Figs. 12 (a) to 12 (d), the shape of the cutout groove of the mounting bracket of the scaffold plate and the portion where the hole is provided may be changed. The mounting bracket 120 shown in FIG.
Is substantially T-shaped, and holes 124 and 126 are provided on both side surfaces. The width S of the notch groove 122 and the diameters T, S of the end portions are formed slightly larger than the diameter of the shaft 34. Hereinafter, the method of using the same will be described.
(1) The lock plate 78 of the hook 72 is moved obliquely upward to release the lock of the bracket 10 of the hook 72 to the arm 16. (2) As shown in FIGS. 13 and 14,
The scaffold plate 130 is turned about 90 degrees downward about the shaft 34. (This state is referred to as a retracted position.) At this time, since the notch groove 68 of the mounting bracket 120 is formed in a substantially T shape, the shaft 34 has a T-shaped tip portion (FIG. 12).
The mounting bracket 120 is located at the position T in FIG.
Never get out of the way. (3) Arm 1 of bracket 10
2 is rotated to the side of the scaffold plate 130 (the upper side in FIG. 13). (This state is referred to as a retracted position.) In this state, the holes 124 and 126 of the mounting bracket 120 and the fixing piece 17 are provided.
The hole 17a is polymerized. (4) The U-shaped pin 50 is moved upward to pull out the lower end 53a of the short shaft 53 from the hole 46 and insert it into the hole 124 of the mounting bracket 120, the hole 17a of the fixing piece 17, and the hole 126. In this state, the scaffold plate 130 and the arm 12 of the bracket 10 are fixed by the lower end 53a of the short axis 53 of the U-shaped pin 50. Scaffolding board 13
When the 0 and the bracket 10 are used again, the above operation is performed in reverse. In this case, since the scaffold plate 130 is pivoted downward, the scaffold plate 130 does not return to its original position without being fixed by the U-shaped pin 50. The lower end 53a of the short axis 53 of the U-shaped pin 50 has a hole 124 and a hole 1 of the fixing piece 17.
By being inserted through the hole 7a and the hole 126, the scaffold plate 130 and the arm portion 12 of the bracket 10 are more securely fixed. Furthermore, the mounting bracket 1 for the scaffold plate 130
Reference numeral 20 designates a notch groove 122 having a substantially T-shape. Since holes 124 and 126 are formed on both side surfaces, the scaffold plate 130 is rotated upward by about 90 degrees, and the arm portion 12 of the bracket 10 is moved to the scaffold plate 130. Can be fixed to the lower end 53a of the short shaft 53 of the U-shaped pin 50 at that position. In FIGS. 13 and 14, the mounting bracket 1 is omitted by omitting the frame and the like of the scaffold plate 130 to show a fixed state.
20 are shown with the notch grooves 122 and holes 124 and 126 appearing.

A mounting bracket 140 shown in FIG. 12 (b) is formed by forming a cutout groove 142 in an inverted L-shape. The width V of the notch groove 142 is formed slightly larger than the diameter of the shaft 34. The mounting bracket 150 shown in FIG. 12C has the notch groove 152 formed in a more polygonal shape than the notch groove 142. The width W of the cutout groove 152 is formed slightly larger than the diameter of the shaft 34. FIG.
The mounting bracket 160 shown in (d) has a notch groove 162 formed in a substantially inverted L-shape, and a hole 164 is provided only on the left side surface in FIG. The width X of the notch groove 162 and the diameter Y of the tip portion are formed slightly larger than the diameter of the shaft 34. Hereinafter, the method of using the same will be described.
(1) The lock plate 78 of the hook 72 is moved obliquely upward to release the lock of the hook 72 on the arm 16 of the bracket 10. (2) As shown in FIG. 15 and FIG.
The scaffold plate 170 is rotated about 90 degrees downward about the shaft 34. (This state is the evacuation position.)
(3) The arm 12 of the bracket 10 is rotated toward the scaffold plate 170. (This state is referred to as a retracted position.) In this state, the hole 164 of the mounting bracket 160 and the hole 17a of the fixing piece 17 overlap. (4) The U-shaped pin 50 is moved upward to pull out the lower end 53a of the short shaft 53 from the hole 46 and insert it into the hole 164 of the mounting bracket 160 and the hole 17a of the fixing piece 17. Lower end 5 of short axis 53 of U-shaped pin 50
3a, the scaffold plate 170 and the bracket 1
The zero arm 12 is fixed. When the scaffold plate 170 and the bracket 10 are used again, the above operation is performed in reverse.
In this case, since the scaffold plate 170 is pivoted downward, the scaffold plate 170 does not return to its original position without being fixed at the lower end 53a of the short shaft 53 of the U-shaped pin 50. Note that FIG.
16 and FIG. 16, in order to show a fixed state, the frame and the like of the scaffold plate 170 are omitted, and the notch groove 16 of the mounting bracket 160 is omitted.
2, a state in which a hole 164 appears. Also, in FIG. 16, the lower end 53a of the short shaft 53 of the U-shaped pin 50 is located lower than shown in the figure at the time of fixing, but is shown above the actual position for the same reason.
