The morning glory unit 5 is installed so as to project diagonally upward from the horizontal plane at a predetermined inclination angle (installation angle) with respect to the temporary scaffolding 1, and holds the morning glory sheet 8 surrounding and holding the morning glory sheet 8 for receiving falling objects. The frame 10, the flap 20, the rod-shaped diagonal member 30, the hanging rope 40, the frame receiving metal fitting 50, and the diagonal material receiving metal fitting 60 are provided.

The morning glory sheet 8 is a rectangular soft double sheet made of resin, and while realizing the weight reduction of the morning glory unit 5, it can reliably catch falling objects and is foldable, so that it is excellent in portability.

The frame 10 is a rectangular frame having the same shape as the morning glory sheet 8 in an assembled state, and includes an upper frame 11, a lower frame 12, a right vertical frame 15, and a left vertical frame 17. The upper frame 11 and the lower frame 12 are detachable from the right vertical frame 15 and the left vertical frame 17, and are fixed with bolts.

The right edge of the morning glory sheet 8 is fixed to the right vertical frame 15, and the left edge is fixed to the left vertical frame 17. In the state where the frame 10 is assembled, the morning glory sheet 8 is the right vertical frame 15. It is stretched tightly between the left vertical frame 17 and the left vertical frame 17 to block the inside of the frame 10 which is a rectangular frame.

On the other hand, when the frame 10 is disassembled and the right vertical frame 15 and the left vertical frame 17 are brought close to each other in parallel, the morning glory sheet 8 can be easily folded and placed at a high place of the scaffolding 1, which is the installation location. The morning glory sheet 8 and the like can be easily carried.

In the frame 10, the portion of the lower frame 12 is rotatably connected to the support column 2 of the scaffold 1 by a frame receiving metal fitting 50 described later about a horizontal axis parallel to the side surface of the scaffold 1. At the left and right ends of the lower end surface of the lower frame 12, vertically erected plate-shaped members are installed as receiving metal fitting connecting portions 13 for connecting to the frame receiving metal fitting 50. A connecting hole 13a is formed in the receiving metal fitting connecting portion 13.

The right vertical frame 15 and the left vertical frame 17 are provided with diagonal lumber connecting portions 16 and 18 on their side surfaces, and the diagonal lumber connecting portions 16 and 18 can rotate about a horizontal axis parallel to the side surface of the scaffold 1. The diagonal lumber 30 is connected to the lumber 30. The diagonal lumber connecting portions 16 and 18 are plate-shaped members erected on the side surfaces of the vertical frames 15 and 17, and connecting holes 16a and 18a are formed. The frame 10 is supported by the diagonal members 30 connected to the diagonal member connecting portions 16 and 18 so as to be installed on the scaffold 1 at a predetermined installation angle.

The flap 20 is a metal plate for closing the gap between the frame 10 and the scaffold 1 so that a falling object does not pass and fall downward, and is rotatably connected to the lower frame 12. ing.

The diagonal member 30 is a stretchable square pipe, and includes an outer cylinder pipe 31, an inner cylinder pipe 35, and a telescopic fixing pin 38 for fixing the expansion and contraction of the outer cylinder pipe 31 and the inner cylinder pipe 35. The inner cylinder pipe 35 is inserted into the outer cylinder pipe 31, and the length of the diagonal member 30 is variable because the outer cylinder pipe 31 and the inner cylinder pipe 35 slide relative to each other.

When installed on the scaffold 1, the outer cylinder pipe 31 located on the lower side is connected to the scaffold 1 side, and the inner cylinder pipe 35 located on the upper side is connected to the frame 10 side. At the lower end of the outer cylinder pipe 31, a plate-shaped member as a receiving metal fitting connecting portion 32 rotatably connected to the diagonal member receiving metal fitting 60 is installed. A connecting hole 32a (not shown) is formed in the receiving metal fitting connecting portion 32.

At the upper end of the inner cylinder pipe 35, a gravity pin (folding pin) 36 for rotatably connecting to the diagonal lumber connecting portions 16 and 18 of the frame 10 is installed. The gravity pin 36 includes a main body pin fixed to the tip of the inner cylinder pipe 35 and a rotating tip pin rotatably connected to the main body pin. The gravity pin 36 is installed so as to project in a direction orthogonal to the extending direction of the inner cylinder pipe 35.

When the gravity pin 36 is inserted into the connecting holes 16a and 18a of the diagonal member connecting portions 16 and 18 with the rotating tip pin coaxially positioned with respect to the main body pin, only the rotating tip pin hangs downward due to its own weight. Therefore, the upper end of the diagonal member 30 is connected so as not to come off from the diagonal member connecting portions 16 and 18. At this time, the tip of the diagonal member 30 is rotatably connected to the frame 10 with the main body pin of the gravity pin 36 as a rotation axis (horizontal axis parallel to the side surface of the scaffold 1).

The telescopic fixing pin 38 is a pin for locking the outer cylinder pipe 31 and the inner cylinder pipe 35 in the sliding direction to fix the length of the diagonal member 30, and the pin is locked in the locking direction (pin hole 33) by a coil spring. It is urged in the direction in which it fits in). By fixing the length of the diagonal member 30 with the morning glory unit 5 installed, the installation angle, which is the inclination angle of the morning glory sheet 8 and the frame 10 with respect to the horizontal plane, can be fixed.

The outer cylinder pipe 31 is formed with six pin holes 33 for inserting the telescopic fixing pin 38 (see FIG. 3), and the inner cylinder pipe 35 is for inserting the telescopic fixing pin 38. A pin hole 37 (not shown) is formed in one place.

The outer cylinder pipe 31 and the inner cylinder pipe 35 are relatively slid so that the pin hole 33 and the pin hole 37 of any one of the first to sixth pin holes 33 face each other in the slide direction. In this state, the telescopic fixing pin 38 is installed at a predetermined position on the outer cylinder pipe 31 and the pin is passed through the pin hole 33 and the pin hole 37 to fix the diagonal member 30 so that it cannot slide. Can be done.

The first pin hole 33-1 formed in the outer cylinder pipe 31 is a lock position where the diagonal member 30 is the longest, and is formed on the side closest to the inner cylinder pipe 35 (upper end side) of the outer cylinder pipe 31. There is. The second pin hole 33-2, the third pin hole 33-3, ..., The sixth pin hole 33-6 is gradually lowered from the position of the first pin hole 33-1 (inner cylinder pipe 35). It is formed at the position moved to the side away from).

As the lock position by the telescopic fixing pin 38 moves to the second pin hole 33-2, ..., The sixth pin hole 33-6, the fixing length of the diagonal member 30 gradually shortens. In the state where the morning glory unit 5 is installed on the scaffold 1, the installation angle of the frame 10 can be changed by changing the length of the diagonal member 30 (see FIG. 5).

FIG. 5 (a) shows a storage state in which the installation angle is a storage angle of 90 °, FIG. 5 (b) shows a retracted state in which the installation angle is a retract angle of 54.5 °, and FIG. 5 (c) shows a retracted state. , Indicates a retracted state where the installation angle is a retracted angle of 45 °. FIG. 5 (d) shows a retracted state in which the installation angle is a retract angle of 35.5 °, and FIG. 5 (e) shows a standard installation state in which the installation angle is a standard installation angle of 26 °.

At the installation site of the morning glory unit 5, when the diagonal member 30 is locked in the first pin hole 33-1 by the telescopic fixing pin 38, the installation angle of the frame 10 is 90 ° standing vertically. Similarly, when the diagonal member 30 is locked in the second pin hole 33-2 by the telescopic fixing pin 38, the installation angle of the frame 10 is 90 °.

In this way, the reason why the different lengths of the diagonal members 30 have the same installation angle of 90 ° is that, as a type of scaffold 1, the frame scaffold and the wedge-tied scaffold have a height per step (in the height direction of the tread plate 3). This is because the intervals) are different. The first pin hole 33-1 is a hole for a wedge-tied scaffold (1.8 m), and the second pin hole 33-2 is a hole for a framework scaffold (1.7 m).

In the present embodiment, the installation interval between the frame receiving metal fitting 50 and the diagonal member receiving metal fitting 60 is substantially the same as the height per step of the scaffolding 1 (interval between the tread plates 3), and the hole 33 for the first pin. Except for the case of fixing in 1, the relationship between the length of the diagonal member 30 and the installation angle of the frame 10 is described on the assumption that the scaffold 1 is a frame scaffold (height per step is 1.7 m). Therefore, when the installation distance between the frame receiving metal fitting 50 and the diagonal material receiving metal fitting 60 is different from about 1.7 m, such as when the scaffolding 1 is a wedge-tied scaffolding, the relationship between the length of the diagonal material 30 and the installation angle of the frame 10 Will also be different.

At the installation site of the morning glory unit 5, when the diagonal member 30 is locked by the hole 33-3 for the third pin, the installation angle of the frame 10 is 54.5 °, and the diagonal member 30 is at the hole 33-4 for the fourth pin. When locked, the installation angle of the frame 10 is 45 °. Similarly, when the diagonal member 30 is locked in the fifth pin hole 33-5, the installation angle of the frame 10 is 35.5 °, and when the diagonal member 30 is locked in the sixth pin hole 33-6. The installation angle of the frame 10 is 26 °.

Generally, the protrusion length of the morning glory unit 5 installed on the scaffold 1 from the scaffold is required to be 2 m or more, and the protrusion length becomes shorter as the installation angle, which is the inclination angle of the frame 10 from the horizontal plane, increases. It ends up. Therefore, the standard installation angle of the morning glory unit 5 is usually set to about 20 to 30 °.

In the present embodiment, the installation angle of 26 ° locked by the hole 33-6 for the sixth pin is set as the standard installation angle of the morning glory unit 5, and since there are obstacles such as utility poles and trees at the site, the standard installation mode is When the frame 10 or the like interferes with an obstacle and the morning glory unit 5 cannot be installed, only the frame 10 that interferes with the obstacle is appropriately adjusted to the evacuation angles of 35.5 °, 45 °, and 54.5 ° for the obstacle. You can avoid things.

Further, the installation angle of 90 ° locked by the holes 33-1 for the first pin and the holes 33-2 for the second pin is such that the morning glory sheet 8 is blown by the strong wind and the morning glory unit 5 and the morning glory unit 5 and the morning glory unit 5 This setting is used when the frame 10 is stored so that the scaffold 1 is not broken. In the stored state where the installation angle is 90 °, which is the storage angle, the morning glory sheet 8 is in close contact with the side surface of the scaffolding 1, so by tying it with a rope or the like, the morning glory unit 5 and the scaffolding 1 may collapse due to strong winds. Can be prevented.

The hanging rope 40 is a rope for lifting the upper frame 11 of the frame 10, and one end thereof is fixed to the upper parts of the vertical frames 15 and 17. When the morning glory unit 5 is installed, the other end is tied to the scaffolding 1 side, and the upper part of the frame 10 is lifted. By using the hanging rope 40 in addition to fixing the length of the diagonal member 30 by the telescopic fixing pin 38 described above, the installation angle of the frame 10 can be maintained more stably.

The frame receiving metal fitting 50 is a clamp fixed to the support column 2 of the scaffold 1, and rotatably supports the lower frame 12 which is the lower part of the frame 10. As a result, the frame 10 is rotatably connected to the scaffold 1 with a horizontal axis parallel to the side surface of the scaffold 1 as a rotation axis.

As shown in FIG. 6, the frame receiving metal fitting 50 has an upper clamp portion 51 that is fastened and fixed to the support column 2, a frame receiving portion 52 that supports the frame 10, and a frame receiving portion 52 that is predetermined to the clamp portion 51. It is provided with an upper gap forming member 55 that is connected and fixed with a gap.

The frame receiving portion 52 includes a gravity pin (folding pin) 53 which is a connecting pin for rotatably connecting the frame receiving portion 52 and the frame 10 (frame receiving metal fitting connecting portion 13), and the gravity pin 53 passes through the frame receiving portion 52. The connecting hole 52a to be formed is formed.

The frame receiving metal fittings 50 are installed at the boundary portion between the two morning glory units 5 which are installed adjacent to each other in the lateral direction without a gap, and support the two frames 10 on both sides. Therefore, the frame receiving portion 52 is provided with two connecting holes 52a for connecting the frame 10 on one side and two connecting holes 52a for connecting the frame 10 on the other side.

As shown in FIG. 7, the gravity pin 53 is passed through the three holes in a state where the receiving metal fitting connecting portion 13 (connecting hole 13a) of the frame 10 is located between the two connecting holes 52a of the frame receiving portion 52. , The frame 10 and the frame receiving metal fitting 50 are connected. The frame 10 can rotate with respect to the scaffold 1 using the gravity pin 53 as a rotation axis (horizontal axis parallel to the side surface of the scaffold 1). Note that FIG. 7 shows a connected state of only the frame 10 on one side.

The gap forming member 55 is a plate-shaped member that extends horizontally from the clamp portion 51 toward the outside while standing vertically, and is connected to the center of the frame receiving portion 52 in the left-right direction. By installing the gap forming member 55, a gap is created between the side surface of the scaffold 1 and the frame 10, and the soundproof panel 4 can be installed in this gap, as will be described later.

The slanted lumber receiving metal fitting 60 is a clamp fixed to the support column 2 of the scaffolding 1 below the frame receiving metal fitting 50, and rotatably supports the lower end of the slanted lumber 30. As a result, the diagonal member 30 is rotatably connected to the scaffold 1 with a horizontal axis parallel to the side surface of the scaffold 1 as a rotation axis.

As shown in FIG. 8, the diagonal member receiving metal fitting 60 includes a lower clamp portion 61 fixed to the support column 2, a diagonal member receiving portion 62 that supports the lower end of the diagonal member 30, and a clamp portion 61 that clamps the diagonal member receiving portion 62. It is provided with a lower gap forming member 65 that is connected and fixed with a predetermined gap.

The diagonal member receiving portion 62 includes a gravity pin (folding pin) 63 for rotatably connecting the diagonal member receiving portion 62 and the receiving metal fitting connecting portion 32 of the diagonal member 30. The gravity pins 63 are welded and fixed to the left and right sides so as to project outward from the vicinity of the tips on both sides of the U-shaped diagonal member receiving portion 62.

When the tip pin of the gravity pin 63 is inserted into the connecting hole 32a of the diagonal member 30 in a horizontally raised state, the tip pin hangs downward due to its own weight, and the diagonal member 30 is rotated so as not to come off from the diagonal member receiving metal fitting 60. It is movably connected.

The gap forming member 65 is a plate-shaped member that extends horizontally from the clamp portion 61 toward the outside while standing vertically, and is connected to the center of the diagonal member receiving portion 62 in the left-right direction. By installing the gap forming member 65, a gap is created between the front side surface of the scaffold 1 and the diagonal member 30. As will be described later, the soundproof panel 4 can be installed in this gap.

The configuration of the morning glory unit 5 according to the present embodiment has been described above. Next, the installation procedure for installing the morning glory unit 5 on the scaffolding 1 at the construction site will be described. The morning glory unit 5 is disassembled and packed in a small package, and is carried to a high place installation place of the scaffold 1, where it is assembled and installed.

As shown in FIG. 2, when the morning glory unit 5 is disassembled, the upper frame 11, the lower frame 12 with the flap 20, the morning glory sheet 8, the right vertical frame 15, and the left vertical frame 17 are integrated. It is divided into two diagonal members 30, two hanging ropes 40, two frame receiving brackets 50, and two diagonal member receiving brackets 60.

At the installation location in a high place, first, the frame receiving metal fitting 50 and the diagonal lumber receiving metal fitting 60 are fastened and fixed to a predetermined place on the support column 2 of the scaffold 1. The installation interval between the frame receiving metal fitting 50 and the diagonal material receiving metal fitting 60 is substantially the same as the height per step of the scaffolding 1, and normally, the lower diagonal material receiving metal fitting 60 is fixed to the support column 2 in the vicinity of the upper side of the tread plate 3. The upper frame receiving metal fitting 50 is fixed to the support column 2 in the vicinity of the upper side of the tread plate 3 which is one step higher.

Subsequently, the lower frame 12 is connected and installed with respect to the frame receiving metal fitting 50. Specifically, as shown in FIG. 7, a region in which the receiving metal fitting connecting portions 13 installed on the left and right sides of the lower frame 12 are sandwiched between the two connecting holes 52a of the frame receiving portion 52 of the frame receiving metal fitting 50. The gravity pin 53 is passed through the three holes of the connecting hole 52a, the connecting hole 13a, and the connecting hole 52a. As a result, the lower frame 12 is rotatably connected to the scaffold 1 about a horizontal axis parallel to the side surface of the scaffold 1.

Subsequently, the morning glory sheet 8 is attached to the lower frame 12. Specifically, the lower ends of the right vertical frame 15 and the left vertical frame 17 that sandwich the morning glory sheet 8 are fixed to the lower frame 12 with bolts. Subsequently, the upper frame 11 is similarly fixed to the upper ends of the right vertical frame 15 and the left vertical frame 17 with bolts. This completes the assembly of the frame 10.

Next, the diagonal member 30 is installed. Specifically, by passing the gravity pin 36 located at the upper end of the diagonal member 30 through the connecting holes 16a and 18a of the diagonal member connecting portions 16 and 18 installed in the vertical frames 15 and 17 of the frame 10, the diagonal member is passed. The upper end of 30 is rotatably connected to the vertical frames 15 and 17 of the frame.

Then, the lower end of the diagonal member 30 is parallel to the side surface of the scaffold 1 by passing the gravity pin 63 of the diagonal member receiving portion 62 of the diagonal member 60 through the connecting hole 32a of the receiving metal fitting connecting portion 32 at the lower end of the diagonal member 30. It is rotatably connected to the scaffold 1 around a horizontal axis (see FIG. 9).

During the installation work of the diagonal member 30, the frame 10 is stored in a state where the installation angle is approximately 90 °, and the diagonal member 30 is stored in the first pin hole 33-1 or the second pin hole 33-2. This is performed in a locked state, that is, in a state where the scaffold is fixed at a length substantially the same as the height per step of the scaffold 1.

Subsequently, after removing the telescopic fixing pin 38, while holding one end of the hanging rope 40, the frame 10 having an inclination angle of 90 ° is hung and tilted to a desired installation angle. When the installation angle is set to 26 °, which is the standard installation angle, the inclination angle of the frame 10 is gradually reduced from 90 ° until the installation angle is approximately 26 °.

When the inclination angle of the frame 10 is approximately 26 °, one end of the hanging rope 40 is tied to the scaffold 1, and the telescopic fixing pin 38 is connected to the sixth pin hole 33-6 and the pin hole 37 facing each other. By inserting and locking the length of the diagonal member 30, the frame 10 is fixedly installed at a standard installation angle of 26 °.

After that, as shown in FIG. 4, the flap 20 is appropriately tilted toward the scaffold 1 side to close the gap, thereby completing the installation work of the morning glory unit 5. Even when the soundproof panel 4 is installed on the side surface of the scaffold 1 for soundproofing, as shown in FIG. 10, the gap forming member 55 of the frame receiving metal fitting 50 and the gap forming member of the diagonal material receiving metal fitting 60 By installing the soundproof panel 4 in the portion of 65, the soundproof panel 4 can be installed without interfering with the morning glory unit 5.

Although the present embodiment has been described in detail above, in the present embodiment, the length of the diagonal member 30 for supporting the frame 10 at a predetermined tilt angle can be adjusted in six stages, and the installation angle of the frame 10 can be set to five. It can be adjusted in stages.

Therefore, at the standard installation angle (26 °), even if the frame 10 that greatly protrudes outward from the scaffolding 1 collides with an obstacle such as a utility pole or a tree, the installation angle is set to 35.5 °, which is the evacuation angle. By adjusting to 45 ° and 54.5 °, the morning glory unit 5 can be installed while avoiding obstacles in the field.

Further, in the present embodiment, when the diagonal member 30 is locked to the first and second longest states for fixing at 90 ° (holes for the first pin 33-1 and holes 33-2 for the second pin), the diagonal members 30 are locked. The installation angle of 30 is 90 °, which is a storage angle, and the diagonal member 30 is stored in a vertical state parallel to the side surface of the scaffold 1. Therefore, even when the frame 10 is raised in a strong wind and tied to the scaffolding with a rope to be fixed, by locking the length of the diagonal member 30, the frame 10 is safely prevented from being blown by the morning glory sheet 8 even in a strong wind. Can be stored.

In addition, with conventional scaffolding, when the scaffolding sheet and frame are raised and stored, the length of the diagonal lumber cannot be adjusted, so it is necessary to remove the diagonal lumber from the scaffolding and store the frame. It was very time-consuming.

On the other hand, in the present embodiment, the diagonal member 30 is configured to be extendable to a state in which the frame 10 is raised so as to be in a stored state at an installation angle of 90 °, and the diagonal member 30 and the scaffolding 1 are connected to each other. The frame 10 can be stored and the strong wind countermeasure work can be efficiently performed only by changing the lock position of the telescopic fixing pin 38 and adjusting the length of the diagonal member without the need to remove the frame 10.

In particular, in the present embodiment, two pin holes 33 (first pin hole 33-1 and second pin hole 33-2) are prepared corresponding to the stored state in which the installation angle is the storage angle of 90 °. One type of morning glory unit 5 can be used for two types of scaffolding (framework scaffolding and wedge-tied scaffolding) with different heights per step.

Further, in the present embodiment, the frame receiving metal fittings 50 and the diagonal lumber receiving metal fittings 60 for connecting the morning glory unit 5 to the supporting columns 2 of the scaffolding 1 are clamped portions 51 and 61 fixed to the supporting columns 2 and the frame receiving portions. Gap forming members 55 and 65 for forming a gap having a predetermined length are provided between the 52 and the diagonal member receiving portion 62.

Therefore, even when the soundproof panel 4 is installed on the side surface of the scaffolding 1 so that the construction noise does not leak to the outside, the soundproof panel 4 is installed in the gap secured by the gap forming members 55 and 65. As a result, the soundproof panel 4 can be installed on the scaffold 1 without interfering with the members constituting the morning glory unit 5 such as the frame 10.

Although the embodiments of the present invention have been described above, the embodiments of the present invention are not limited to the above embodiments, and various modifications can be made without departing from the gist of the present invention. For example, the size, shape, material, etc. of the members constituting the morning glory unit can be changed as appropriate.

Further, in the above embodiment, the standard installation angle of the morning glory unit is 26 °, the evacuation angles for avoiding obstacles are 35.5, 45 °, 54.5, and the storage angle is 90 °, but the standard installation angle and the evacuation angle are appropriate. It can be changed. Further, it is necessary to set at least one evacuation angle, and it is desirable to set two or more evacuation angles.

Further, in the above embodiment, as the telescopic fixing member for fixing the length of the diagonal member, a fixing pin to be inserted into a pin hole formed in the outer cylinder pipe and the inner cylinder pipe is adopted, but as the telescopic fixing member. Is a member capable of fixing the expansion and contraction of the diagonal member, such as a combination of bolts and nuts and screwing, and members having other configurations can be appropriately adopted.
