Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transportation system for building materials used for constructing a multi-storey building such as a multi-storey housing complex.

[0002]

2. Description of the Related Art A conventional method of transporting building materials will be described by taking a multi-storey housing as shown in FIG. 6 as an example. As shown in the drawing, a plurality of dwelling units are arranged with a boundary wall 2 therebetween.
In the construction work of a multi-story apartment T in which an open corridor 3 is arranged on one side and a balcony 5 is arranged on the other side, each dwelling unit ~
When a gypsum board for carrying out the interior of the above is carried into each dwelling unit, conventionally, the construction elevator 11 as the vertical moving means installed adjacent to the open corridor 3 has been used for lifting the gypsum board. .

Then, the gypsum board lifted up to a predetermined floor by the construction elevator 11 was carried out from the construction elevator 11 to the open corridor 3 by human power, and was carried into each dwelling unit through the open corridor 3.

The gypsum board for interior use is usually 3LDK, although it depends on the size of each dwelling unit in a multi-story apartment house.
In the type of dwelling unit, it is about 40 pieces per unit and weighs 5
About 00kg is required.

Open the corridor 3 with such a quantity of gypsum board
Wheelbarrows may be used to transport each unit to each dwelling unit, but since the entrance to each dwelling unit is only the width of the entrance door, it is necessary to load a grabbread with gypsum board to handle it. In particular, during construction, there is a step on the floor surface due to construction wiring and members to protect it, and scraps cut off at the site during construction. In addition, since there is a step of about 50 mm between the open corridor 3 and the indoor slab, a great deal of effort is required to overcome the step, and normally when a large weight is loaded on one wheelbarrow. Two to three workers are required, and if the weight can be carried by one person, the transportation efficiency is poor.

In the case of a multi-story housing, a rising part (a rising part of the tip of the nose of a cantilever slab) is often formed at the end of the open corridor 3, and in this case, it is provided at the end of the open corridor. Stage 12 for loading heavy materials
Difference between the floor and the floor of the open corridor 3 (250mm-1300mm
Temporary slopes corresponding to the degree will be used, and more effort will be required to handle the wheelbarrow.

[0007] Therefore, generally, without using a wheelbarrow, unloading from the construction elevator 11 to the open corridor 3 and transporting / carrying from the open corridor 3 to each dwelling unit 3 to 3 are carried out.
The reality is that it is done by four people.

However, according to this method, it takes a long time to unload the work elevator 11, and during that time, the use of the work elevator 11 is restrained, or a plurality of workers are required. There is a problem that it takes a lot of labor.

Further, in order to facilitate the loading and unloading of materials to and from the construction elevator, a slide frame configured to be switchable between a state of being housed in the construction elevator and a state of projecting from the construction elevator, and a slide frame formed thereon A construction elevator incorporating a loading and unloading device with a trolley mounted so as to be capable of reciprocating movement is disclosed in Japanese Utility Model Laid-Open No. 5-6233.
No. 8, which is proposed by JP-A-5-97356.
A device for vertically moving a dolly itself with casters has also been proposed, as in Japanese Patent Laid-Open Publication No.

These devices can be expected to have a great effect in terms of facilitating the loading and unloading of building materials to and from vertical moving means such as a construction elevator. With regard to the horizontal movement of carrying in, there are unsolved problems such as multiple workers being required and a lot of human labor is required, and a great deal of labor is required for overcoming a step or climbing and descending a slope. There is almost no difference from the above-mentioned conventional example.

As a solution to such a problem, the present inventor has devised a construction material transfer system as shown in FIGS. 7 and 8.

This construction material transfer system is provided with wheels 14
A power source for rotating a is provided (for example, a hydraulic motor driven by an electric motor using a battery as a power source), and a roller conveyor 14b having a large number of rollers rotatably mounted on the upper surface is provided. The required number of trolleys 14 are placed on the unloading floor, while the construction elevator 11
A large number of rollers are rotatably mounted on the lifting floor 11a in the vertical moving means such as the above, and on the intake stage 12 fixed to the end of the open corridor 3 on the unloading floor with angle members, bolts, nuts, etc. Roller conveyor 1 formed by pivoting
In addition, the open corridor 3 on the unloading floor is equipped with a hydraulic unit powered by AC 100V and a double-acting hydraulic cylinder driven by the hydraulic unit, and has a large number of balls rotatable on its upper surface. An elevating table 13 equipped with a ball conveyor 21 composed of bearings is installed to absorb the height difference between the take-in stage 12 and the upper surface of the carriage 14.

Reference numeral 22 in the figure denotes a pedestal that can be moved up and down manually, and is installed in a dwelling unit. Trolley 14
May be operated by an operator on board, or may be driven unattended by automatic control using a computer.In this embodiment, wired remote control is possible. An operator holds the operation box and walks near the carriage 14 to control the carriage 14.

The operation of this transfer system is as follows. For example, when the building material W on the ground is carried into a dwelling unit on the unloading floor, first, one worker operates the forklift 15 to load the building material W together with the pallet 23 on the vertical moving means 11.

Next, another worker boards together with the building material W in the vertical moving means such as the construction elevator 11, and vertically moves the building material W to the unloading floor by the vertical moving means.

On the unloading floor, the worker who has vertically moved together with the building material W horizontally moves the building material W together with the pallet 23 to the lifting table 13 via the stage 12.

Thereafter, the height of the elevating table 13 is adjusted to the height of the trolley 14, and the building material W is loaded together with the pallet 23 on the trolley 14 laterally attached to the elevating table 13. In this case, the carry-out direction from the lift table 13 to the carriage 14 is at a right angle to the carry-in direction from the take-in stage 12 to the lift table 13, but a ball conveyor 21 is provided on the upper surface of the lift table 13. Therefore, the transfer direction can be freely changed.

Next, the above-mentioned worker operates the carriage 14,
The trolley 14 is horizontally moved to each dwelling unit through the open corridor 3, and the building material W together with the pallet 23 is once placed on the cradle 22 to be unloaded, and the trolley 14 is returned to its original position. In addition, it is desirable that the number of the carriages 14 is two or more in order to reduce the working time.

According to this, the construction material W can be carried in by one worker for one trolley 14 and one worker for operating the forklift 15, and the trolley 14 can be equipped. Since the wheels 14a are driven by the power source described above to move the carriage 14 horizontally, it is possible to easily climb over a step and reduce labor.

However, in the above transport system,
Roller conveyors 19 and 2 are provided on the lifting floor 11a and the intake stage 12 in the vertical moving means such as the construction elevator 11.
Since 0 is provided, it is difficult to ensure safety because there is a risk that an operator may accidentally put his / her foot on the roller conveyors 19 and 20 during lifting, horizontal movement, or other walking. There was room for improvement.

[0021]

SUMMARY OF THE INVENTION The present invention has been made with the above points in mind, and the purpose of the present invention is to reduce labor and to improve the floor surface of the vertical moving means. The purpose of the present invention is to provide a material conveyance system that can easily ensure safety because special equipment such as a roller conveyor is not required.

[0022]

The technical means taken by the present invention to achieve the above object are as follows. That is, the material transfer system according to the first aspect of the present invention is equipped with a vertical moving means provided over a plurality of floors of a building and a power source capable of getting on and off the vertical moving means and rotating wheels. It is equipped with a trolley, and on the loading floor, materials are loaded on the trolley and the trolley is loaded into the vertical moving means, and the trolley is vertically moved after the materials are vertically moved to the unloading floor by the vertical moving means. It is characterized by unloading from the means to the unloading floor, horizontally moving the trolley to a predetermined position, and unloading the material from the trolley.

The material transfer system according to the second aspect of the present invention is equipped with vertical moving means provided over a plurality of floors of a building, and a power source capable of getting on and off the vertical moving means and rotating wheels. And a loading stage provided on at least the unloading floor.On the loading floor, loading of materials on the trolley and loading of the trolley onto the vertical moving means are carried out, and the vertical moving means is used to reach the unloading floor. It is characterized in that after the material is vertically moved together with the dolly, the dolly is unloaded from the vertical moving means through the loading stage to the unloading floor, and the dolly is horizontally moved to a predetermined position to unload the material.

The material transfer system according to the third aspect of the invention is equipped with a vertical moving means provided over a plurality of floors of a building and a power source capable of getting on and off the vertical moving means and rotating wheels. And a loading stage and an elevating table provided at least on the unloading floor.On the loading floor, loading of materials onto the trolley and loading of the trolley onto the vertical moving means are performed, and the load is moved by the vertical moving means. Characteristically, the material is vertically moved to the unloading floor together with the dolly, and then the dolly is unloading from the vertical moving means to the unloading floor via the loading stage and the lifting table, and the dolly is horizontally moved to a predetermined position to unload the material from the dolly. I am trying.

In any of the first to third inventions, the loading of the material on the truck and the loading of the truck on the vertical moving means performed at the loading floor may be performed first. In other words, the material may be loaded onto the trolley, and then the trolley may be loaded into the vertical moving means, or the material may be loaded onto the trolley that has been loaded into the vertical moving means in advance. It is preferable that the trolley is configured such that it can be remotely controlled by wire. The building may be an office building, a hospital, a hotel, or the like, or may be a multi-story housing complex.
When the building is a multi-story housing with an open corridor on the side, the intake stage is installed in a state of overhanging from the open corridor, and the lifting table is installed in the open corridor. The vertical moving means may be a lift, a crane, a permanent elevator, etc. in addition to the construction elevator. The materials referred to in the present invention are meant to include construction materials, waste materials thereof, residual materials, medical equipment, exhibits, and the like. The use of the permanent elevator is effective for building renovation work and for carrying in and out large heavy exhibits in the building.

[0026]

According to the above construction, since the wheels are driven by the power source mounted on the truck to move in and out of the vertical moving means and to move the truck horizontally, no great labor is required.
It is possible to easily climb over a step and reduce labor. Further, since the dolly gets on and off the vertical moving means by its own power, it is not necessary to provide a roller conveyor or the like on the floor surface of the vertical moving means.

Reference numeral 15 is a forklift used when loading the building material W from the outside of the building to the construction elevator 11, as in the case where the loading floor is on the ground 18. Reference numeral 16 denotes an unloading device arranged on the unloading floor, which includes wheels 16a and a fork 16b which is vertically driven by an electric motor or hydraulic cylinder (not shown). In this embodiment, a simple fork is used in which the hydraulic cylinder is driven (pressure oil supply) by stepping on the pedal.

Next, the operation of the structure of the above embodiment will be described.

(1) Building material W loaded on the truck 17
One worker uses a forklift 15 to place a pallet 2 on an empty carriage 14 waiting inside the construction elevator 11.
3 is loaded.

(2) Another worker boards the construction elevator 11, and this worker operates the construction elevator 11 to vertically move the building material W together with the truck 14 to the desired unloading floor. . This worker is a construction elevator 11
Although it may be a dedicated worker, it is desirable that the worker who operates the carriage 14 moves the construction elevator 11 in order to reduce human labor.

(3) On the unloading floor, the wheels 14a are driven by the power source mounted on the carriage 14 to allow the carriage 14 to travel by itself, to pass the loading stage 12, and to move up and down the table 13.
To move on.

Are arranged in a straight line across the boundary wall 2, and an open corridor 3 is arranged on one side of these dwelling units to a group, and an open corridor 3
In loading the interior plaster board as the building material W into each dwelling unit on the 1st to 4th floors in the multi-storey housing T under construction in which the construction elevator 11 is installed near one end in the longitudinal direction of Table 2 shows the results of simulations using the method for transporting building materials and the above-described system for transporting building materials.

[0045]

[Table 2]

Strictly speaking, in Table 2 of the present transport system, there is a hop-on / off time of the dolly between BC and EF, but it is not expressed because it is very small. Construction elevator 11
Has a loading capacity of 900 kg, and the ascending / descending speed is 0.15 m.
/ Sec. In the conventional method of transporting building materials, there are four workers (one for operating the forklift 15 and three for manually transporting gypsum board), and one person has four gypsum boards at one time (50 kg in weight). Was to be transported. The specifications of the carriage 14 are as shown in Table 1, and 40 pieces of gypsum board (500 kg in weight) are loaded on the carriage 14 at one time. There are two workers (one for operating the forklift 15,
1 person was used to operate the trolley 14. In addition, in the case where two carriages are used in the present transportation system, after the first carriage is lifted, the construction elevator 11 is lowered in an empty state to load the second carriage. , Construction elevator 1
The broken line showing the descent of No. 1 in the first empty state is omitted.

From Table 2, the following can be understood. That is, as described above, 40 gypsum boards (500 kg in weight) are required for each dwelling unit, so that 240 g (3000 kg in weight) is required for all dwelling units on the 4th floor.

In the conventional work method, since the trolley 14 is not used and the weight of the trolley 14 is not applied, it is possible to lift as many gypsum boards as possible, and the elevator 11 for construction works 1
The lifting weight for each round was 800 kg. Therefore, the required number of gypsum boards can be lifted by performing the lifting operation four times.

On the other hand, in the above transport system,
The weight of one lift by the construction elevator 11 is 500 kg.
Therefore, in order to lift the required number of gypsum boards, it is necessary to perform lifting work six times.

However, since the carriage 14 is used,
Since the time required for the loading work A and the time required for the horizontal transfer (outward route) C to the horizontal transfer (return route) D are shorter than those of the conventional working method, each lifting operation is short. Is done in about the same time as the conventional work method,
Gypsum board can be loaded into all dwelling units. In other words, in the conventional work method, four workers were required, but with the above-described transport system, two workers can work in approximately the same time.

When two carriages 14 are used, as shown in Table 2, the construction elevator 11 is lowered while one carriage 14 is moving horizontally, and the second carriage 14 is moved. Loading work can be done for 14 and forklift 15
The total work time will be reduced to half by one person for each of the two operations and one for each of the two trucks, for a total of three people.

Although the vehicle weight of the trolley 14 depends on the loading capacity of the construction elevator 11, in the case of a general construction elevator 11, the vehicle weight is 1/3 or less of the loading capacity of the construction elevator 11. By suppressing the above, the carrying capacity of the carrying system according to the present invention is effectively exhibited. At the same time, it is preferable that the loading capacity of the trolley 14 is at least twice the weight of the vehicle body. Further, in consideration of the load on the slab of the building, the trolley 14 is preferably less than 1 ton including its own weight in the maximum loaded state.

In the above embodiment, the loading floor is the first floor, and the building material W is loaded from the outside of the building onto the trolley 14 waiting in the construction elevator 11. However, as the loading floor, The floor is not limited to the first floor as long as it is the floor that is the starting point of transportation. For example, when transporting from the 2nd floor to the 5th floor,
The second floor is the loading floor, and when transporting from the third floor to the second basement, the third floor is the loading floor. However, in these cases,
As shown in FIG. 3, the loading stage 12 and the lifting table 13 are installed not only on the unloading floor but also on the loading floor, and the trolley 14 loaded with the building material W is loaded onto the lifting floor 13 and the loading table. You will get into the construction elevator 11 via the stage 12.

In each of the above embodiments, the multi-storey housing T having the open corridor 3 composed of the cantilevered slab is assumed as the target of the transfer work. Therefore, the construction elevator 1
1 is provided between the open corridor 3 and the open corridor 3, and the step between the intake stage 12 and the floor of the open corridor 3 is a carriage 1
Although the lifting table 13 is provided so as not to hinder the traveling of No. 4, the lifting table 13 may be omitted when the step is 50 mm or less or when the capturing stage 12 is provided without the step. Further, when the construction elevator 11 is provided so as to be in close contact with the open corridor 3 and the step difference is 50 mm or less, the intake stage 12 and the lifting table 13 are
Both will be omitted.

If there is a building behind the site where a large truck cannot be entered, the construction elevator 11
Until the building material W is carried in by the trolley 14 and the trolley 1
4 may be placed directly on the construction elevator 11.

In each of the above embodiments, the vertical moving means may be a construction elevator 11, a lift, a crane or the like, or a permanent elevator. Further, in each of the above-described embodiments, the description has been given on the premise that the material is carried in, but the material is not carried out because the material carrying out such as waste material and residual material is the reverse step of the carrying-in step. Further, the present invention can be applied not only to the transportation of building materials, waste materials thereof, and residual materials, but also to the transportation of medical equipment in hospitals and the transportation of exhibits in exhibition halls.

[0057]

According to the present invention, which has the above-described structure, the wheels are driven by the power source mounted on the truck to move in and out of the vertical moving means and to move the truck horizontally. Can be easily overcome, labor can be reduced, and safety can be easily ensured because a roller conveyor or the like is not provided on the floor surface of the vertical moving means.
