DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is used not only for a bridge such as a highway, but also for assembling a scaffold by suspending it with a chain or the like. The hanging shelf scaffolding protection side wall can also be used for a conventional hanging shelf scaffold.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a perspective view for explaining a method of constructing a hanging shelf scaffolding protective side wall, FIG. 2 is an explanatory view showing a state in which a frame is locked to a frame supporting member, and FIGS. 3 to 5 show a locking mechanism. FIG. 6 is a schematic diagram illustrating a frame and a replacement member. 1 is a suspension chain, 2 is a main beam, 3 is a shelf, 4 is a locking member, 12 is a frame support member, 14 is a frame, and 17 is a replacement member. To the main beams 2, 2, a locking member 4 which can be engaged independently to lock a support member 12 supporting the protective side wall is attached. The locking member 4
Any shape can be used as long as it can stand on its own. For example, as shown in FIG. 3 to FIG. 5, a structure composed of a support 5, a diagonal member 6, and a pedestal 7 is conceivable. Then, as shown in FIG. 3A, the pedestal 7 is attached to the main beam 2 by an attachment mechanism such as a screw 8 and is held independently. As the attachment mechanism, any other mechanism can be used. For example, as shown in FIG. 3B, a locking mechanism 10 which engages with a pin 9 provided on the main beam 2 is used.
And a fixing method using a combination of both the screw 8 and the locking mechanism 10 is also conceivable.

Further, as shown in FIGS. 5 (a) to 5 (c),
The diagonal member 6 is configured to be extendable, and the pedestal 7 and the column 5 are rotatably supported by the pin shaft 11 and the like, and the angle of the column 5 is changed by the extension mechanism 20 to increase the work space. You can also.

The diagonal member 6 is formed as shown in FIGS.
Depending on the receiving strength of the column, not only one but also two to four, etc., can be considered.

Further, an engaging portion 13 provided with an attachment mechanism such as a screw is formed at the upper end of the locking member 4, that is, at the upper end of the column 5. The frame support member 12 is fixed to the engaging portion 13 as shown in FIG. The engagement portion 13 and the frame support member 12 may be detachably attached, or may be configured integrally.

The frame support member 12 is provided with a receiving portion 16 at a predetermined position for engaging with a claw member 15 provided on the frame 14 shown in FIG. The frame body 14 has an opening formed in the center, and a locking claw 18 for locking a replacement member 17 such as a painting panel is swingably attached to the frame body 14, and is held when the replacement member 17 is mounted. , Constituting a protective side wall. A packing member 19 made of rubber or the like is adhered to the outer periphery of the frame 14, so that when the plurality of frames 14 are juxtaposed right and left and up and down, the respective frames 14 come into close contact with each other. . In particular, when a replacement member having a soundproofing member is used, the soundproofing effect can be enhanced, and it is possible to prevent equipment, tools, and the like from falling through gaps. The mounting position of the claw member 15 is designed so as not to obstruct equipment associated with scaffolding, such as a hanging chain (see FIG. 1).

The replacement member 17 is shown in FIG.
(C) Painting panels shown in (c), other than those that provide aesthetics, are formed of soundproofing members to prevent noise in the workplace from leaking to the outside, and have a net-like shape that has a ventilation effect and prevents falling objects. It can be replaced or used as necessary, such as a commercial advertising board or a commercial advertising board.
Further, in a strong wind or the like, the swing of the scaffold due to the wind can be reduced by removing one or a plurality of replacement members. In addition, the frame 14 has a double structure as shown in FIG. 2B at the uppermost portion of the protective side wall or at both left and right ends, and one of the frame members can be slid in the long side direction or the short side direction. By holding, the length can be adjusted at the uppermost portion or both ends, and the gap can be eliminated.

Next, a method for constructing a hanging shelf scaffold according to the present invention will be described. 7 is an explanatory view for explaining a mounting state of a hanging shelf scaffold, FIG. 8 is a sectional view showing an engagement state between a main beam and a shelf plate in another embodiment, and FIG. 9 is a sectional view showing a honeycomb structure. It is. 2 is a main beam, 3 is a shelf plate forming a scaffold, 21
Is a concave portion, 22 is a locking portion, 27 is a suspension protrusion, and 28 is a holding member for connecting components. As shown in FIG. 7, the shelf 3 is engaged between the pair of main beams 2, 2 suspended by a chain. As shown in FIGS. 7B to 7E, the main beam 2 is integrally formed with a T-shaped suspension projection 27 at an upper section. Further, the suspension chain 1 is used to suspend the suspension projection 1 via a component coupling clamping member 28 which can be clamped by the suspension projection 27. After being held in engagement with the suspension projection 27, the component coupling holding member 28 is hung by a crane or the like via a commonly used coupling tool. Further, in the present invention,
Instead of passing a cross beam called a roll between these main beams,
The shelf 3 is placed over the suspended main beam 2,
The end of the shelf 3 is fitted into a recess formed by the T-shaped suspension projection 27 and fixed with a bolt 30. As a result, there is no gap in the hanging shelf scaffolding, and a scaffold is formed by the cross beam and the shelf, and the long sides of the shelf are sequentially engaged to form a hanging shelf scaffold as in the conventional case. It does not protrude. In addition, in the conventional hanging shelf scaffold, when a part of the shelf is taken, the engagement relationship with other shelves is broken, and an unnecessary part is removed, or the cross beam is exposed even after the removal,
There is a problem that work is difficult. On the other hand, in the hanging shelf scaffold of the present invention, it is possible to remove a part of the shelf if necessary, whereby a complete space is opened in the scaffold and work becomes easier. In addition, if the main beam is used, since the suspension projections are continuous in the longitudinal direction, any position of the main beam can be clamped by the clamping member in the hanging shelf scaffolding assembly work, and the assembling work can be performed. Becomes extremely simple. According to this method, it can be formed only by extruding a T-shaped projection on the main beam, and does not require any special processing such as welding.
It has a simple configuration. As a shelf locking mechanism for another hanging shelf scaffold, as shown in FIG. 8, a locking portion 22 for engaging with the concave portion 21 of the main beam 29 is provided on the shelf 35, and the locking portion 22 is connected to the main beam. 29, the shelf board 35
May be defined and held between the main beams 29, 29. Therefore, when assembling the shelf, the scaffold can be quickly formed by a simple operation by engaging the engaging portion 22 of the shelf 35 with the main beam 29 suspended by the suspension chain. Further, FIG.
As shown in (a), a reinforcing member 2 made of a honeycomb structure formed of paper, plastic, or the like is provided inside a shelf plate 36.
3 is inserted. Although the effect provided by the honeycomb structure is a well-known matter, the shock applied to the shelf can be eliminated by dispersing the shock inside the honeycomb structure. Therefore, by inserting the reinforcing member of the honeycomb structure into the shelf, a strong shelf can be obtained, and the plate itself can be formed thinner and lighter than before.

[0013] Similarly, as shown in FIG.
If the reinforcing member 23 of the honeycomb structure is fitted into the inside of
The main beam 37 can also be reinforced, and a thin, lightweight and strong main beam can be obtained. Therefore, by inserting the honeycomb structure, the strength of the members can be increased, sufficient strength can be maintained even without the cross beam conventionally required, and the assembly work is extremely simple because the weight can be reduced. Can be done.

[0014]

As described above, the present invention does not require a cross beam which has been used in the prior art, and makes it possible to assemble a hanging shelf scaffold extremely efficiently and easily. The hanging shelf scaffold can be reliably formed, and a part of the shelves can be removed to form a necessary space. In addition, the replacement member can provide any effects such as noise reduction in the workplace, aesthetic appearance, advertising effects, etc., a very simple configuration, a stable finish can be obtained by anyone, and conditions such as strong winds. The change allows quick response such as replacement of a replacement member. Further, by providing the self-supporting locking member, it is possible to easily prevent the danger of the work place, enlarge the work space, and the like. In addition, since the frame for the suspended scaffolding protective side wall can be extended in the longitudinal direction or the short side direction, the length of the frame at the end can be adjusted, and there is no gap in the protective side wall, and there is a danger of falling. It can also be prevented. Furthermore, by forming a T-shaped suspension projection on the main beam and providing a holding member for component connection, the main beam can be suspended at an arbitrary position on the main beam, and the shelf can be fitted to the suspension projection. By joining, the shelf can be securely held, and the assembling work of the hanging shelf scaffold can be performed very simply and reliably.
