Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a stage for carrying in and out of suspended loads, which is provided in an opening in a part of a floor or wall of a building for carrying in and out of materials. It is related to.

<Conventional technology> At construction sites in urban areas, materials are transported in and out.
Openings are created in the floors of each floor inside a building, and a crane is used to unload the cargo and bring the suspended cargo onto each floor.

In such a case, in the conventional method, as shown in FIG. This is done by the worker taking in the information.

<Problems to be Solved by the Present Invention> The conventional techniques described above have the following problems.

(i) When loading and unloading the suspended load 5, remove the handrail 7 to prevent falling.

As a result, work is carried out under extremely dangerous conditions.

In order to take in the suspended load 5 suspended by the crane 6, it is necessary to pull the suspended load 5 in the horizontal direction.

As a result, the work tool is pulled in the opposite direction to the retracting direction, increasing the risk of falling.

(c) When the suspended load 5 is taken in, the wire 61 of the crane 6 hits the floor 4 of the upper floor and is pulled further inward.

Therefore, there is a possibility that the wire 61 may be damaged.

(2) It is necessary to remove and attach the handrail 7 every time the suspended load 5 is carried in and out.

Therefore, the work becomes complicated and the handrail 7 may not be attached until the next loading/unloading operation, which is dangerous.

Kuho> The worker needs to move when pulling the suspended load 5 laterally.

For this reason, wearing a safety belt makes it difficult to move and work, so it is often dangerous to work without a safety belt.

OBJECT OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and provides a stage for loading and unloading suspended loads that can safely and easily carry out loading and unloading operations for suspended loads. The purpose is to provide.

<Configuration of the Present Invention> An embodiment of the present invention will be described below with reference to the drawings.

In this embodiment, a case will be described in which an opening is provided in a floor surface, but the present invention can also be applied to a case in which an opening is provided in a wall surface of a building.

Stage (Fig. 1.2) The stage 1 is a plate having a sufficient area on which the hanging load 5 can be placed.

The stage 1 may be, for example, a structure in which scaffolding boards 12 are attached to the upper surface of Hfflls or steel members having an inverted C-shaped cross section arranged at equal intervals.

A protrusion 13 is formed at one end of the Hall, and a long hole 14 is formed near the protrusion 13 along the long side direction of the Hall.

Further, a fastener 16 having a hole 15 is attached to the lower part of the other end of the Hall, and a pivot fitting 18 having a pin 17 is attached to the upper part thereof.

Entrance〉Fence body (Fig. 1.2) Fence body 2 is formed into a plate-like body by placing nets etc. on steel rods, for example, and the width and height are determined taking into consideration the fall prevention effect. .

A projection 21 is formed at one end of the fence 2, and a long hole 22 is formed near the projection 21 along the long side direction of the fence 2.
Attach the shaft support fitting 23 that has been opened.

Kuha〉The receiver is a metal fitting (Fig. 1.2) The shape of the receiver and the metal fitting 3 is, for example, two parallel plates, one with the middle part and the other with the end at right angles. It is composed of plates connected in the direction.

As shown in FIG. 2, this receiving metal fitting 3 has a short locking part 31 and a long fastening part 32 located in parallel.

and a bolt hole is opened in the plate connecting them.

A hole 33 is formed in the fastening part 32.

A pivot fitting 35 having a pin 34 is attached between the locking part 31 and the fastening part 32.

<2> How to assemble each member (Fig. 1.2) Fit the pins 17 of the pivot bracket 18 of the stage 1 into the long holes 22 of the pivot bracket 23 of the fence body 2, and assemble the fence body 2. Attach rotatably.

The bracket 3 is fixed to the floor body 4 at the edge of the opening 41 with bolts 36.

At this time, the locking portion 31 and the fastening portion 32 are fixed so as to face the center of the opening 41 and with the locking portion 31 facing upward.

The metal fittings 3 of this receiver are attached at two places at a certain interval, but before fixing them, the elongated holes 14 at both ends of the stage 1
The pin 34 of the pivot bracket 35 is fitted to the stage 1, and the stage 1 is rotatably mounted.

The stage 1 is attached so that the scaffolding board 12 is positioned upward.

<How to bring in and take out suspended loads> The method of carrying in and out a hanging load according to the present invention is carried out as follows.

Figures 1 to 3) First, the hanging load 5
The stage l of the floor where the goods are carried in and out is extended into the opening 41.

Stage 1 on other floors is stored (.

When the stage 1 is extended, the base end of the stage 1 hits the locking part 31 of the metal fitting 3.

Therefore, the stage 1 can maintain a horizontal state.

Then, the fence body 2 is raised in the right angle direction, and the protrusion 21 is pulled down and fitted into the hole 15 of the fastener 1'6.

Therefore, the fence body 2 does not swing and can reliably achieve the effect of preventing falls.

Exit> Loading and unloading the suspended load (Fig. 3) Next, as shown in Fig. 3, the wire 61 of the crane 6
The suspended load 5 is lowered onto the stage 1.

Alternatively, the crane 6 lifts the suspended load 5 that has been transported to the stage 1.

At this time, the crane 6 can lift or suspend the load 5 only in the vertical direction.

Furthermore, since the stage l on the upper floor is housed, the wire 61 will not hit it.

kuha〉 Storing the stage (Figs. 1 to 3) After the work of loading and unloading the hanging load 5 is completed, the stage 1 is stored.

First, the fence 2 is pulled upward to disengage the protrusion 21 and the fastener 16.

Then, it is rotated to the scaffold board 12 side and folded.

Next, the stage 1 is pulled horizontally and raised until it is perpendicular to the floor 4.

Then, the protrusion 13 is fitted into the hole 33 of the shaft support fitting 35.

Therefore, the stage 1 does not swing and can reliably function as a fall prevention fence.

When extending the stage 1 again, first pull it upward to disengage the protrusion 13 and the pivot bracket 35, and then
Rotate it so it sticks out.

<Effects of the Present Invention> Since the present invention has been described above, the following effects can be expected.

Previously, when loading and unloading suspended loads, the handrails to prevent falls were removed.

As a result, work is carried out under extremely dangerous conditions.

However, in the case of the present invention, even when loading and unloading suspended loads, the foldable fence attached to the stage allows
It is possible to prevent workers from falling.

Therefore, no matter how high the work is, it is possible to load and unload suspended loads with safety first.

Conventionally, when a crane is used to retrieve a suspended load, it is necessary to pull the suspended load laterally, which can cause the worker to be pulled in the opposite direction to the retracting direction, creating a high risk of falling.

In contrast, in the present invention, since the suspended load can be placed on the projecting stage, the lifting operation by the crane can always be performed in the vertical direction.

Therefore, there is no need to pull the shipment horizontally, and when the worker pulls the shipment in the opposite direction, the crane wire hits it and pulls it further inward.
Wire damage may occur.

In the present invention, only the stage on the floor that takes in the suspended load can be extended, and the stages on the other upper floors can be stored.

Therefore, the wires will not hit the floors on the upper floors.

Therefore, it is economical as there is no damage to the wire, and
It is highly unlikely that an accident will occur due to wire cutting.

2) Previously, it was necessary to remove and install handrails every time a suspended load was loaded or unloaded, which made the work complicated, and the fence was sometimes not attached until the next loading/unloading operation. ,It is a danger.

However, according to the present invention, loading and unloading of suspended loads can be carried out simply by extending and folding the stage and fence.

Therefore, compared to the conventional method, the work can be performed very easily and quickly.

Kuho〉In the past, workers had to move when pulling suspended loads laterally, so if they wore a safety belt, they could not move.
Unable to work.

However, in the present invention, it is only necessary to lift and lower the hanging load straight onto the stage.

Therefore, it is not necessary to pull the hanging load laterally.

Therefore, since the worker does not have to move, he or she can work while wearing a safety belt.

〉 Hanging loads can be lowered vertically onto the stage and lifted vertically from the stage.

Therefore, the work can be done easily and the work time is shortened.
