Description

INDUSTRIAL APPLICABILITY According to the present invention, when a long folded plate type metal roof is laid, a folded plate roof plate such as a long roof plate material can be easily and quickly transported to a predetermined position at a roof construction site, and is transported. It relates to a construction transfer device that can significantly reduce the labor of workers at the time.

Conventionally, in the case of a folded plate type metal roof and a large area, a molding machine for forming the roof plate is first installed at the height of the roof construction site of the structure. The molding machine is to be removed when the roof construction work is completed. A worker who placed the roof plate formed by molding from a metal plate material by this molding machine at appropriate intervals at the roof construction site so as to be in the same direction as the longitudinal direction thereof, placed the roof plate. It is supported and transported and is roofed on structural materials such as beams. However, since the molding machine is a heavy object and is installed in a high place, an extremely strong scaffold is assembled, and it is extremely difficult to move the molding machine easily.

Therefore, in the case of roofing a metal folded plate roof, generally, the molded folded plate roof plate is transported from the vicinity of the installation location of the molding machine and roofed in sequence. That is, the worker had to carry the tightening roof plate from the thatched roof near the installation location of the molding machine to the unthatched roof plate. In the transportation work, all the workers must move in step with each other so as not to cause deformation of the roof plate material during transportation, which means that the stride length and walking speed of the workers are different from each other, especially the roof plate material. However, when the length was long, the weight was heavy, a large number of workers were required, and it was difficult to transport the tightening roof plate.

For this purpose, various transport machines for transporting folded plate roof plates have been developed at construction sites, and the main ones are disclosed in the patent documents. The main ones are extremely complicated in structure, cumbersome to handle, and it took a long time for workers to get used to them. In particular, most of the conveyors are provided with traveling members such as wheels, rollers or sleds that come into direct contact with the rails. In such a structure, if the building material to be transported is long and heavy, friction occurs between the transport machine and the rail, which puts a heavy burden on the worker and also causes noise in the work. It is easy to occur.

Further, the use of an air pallet or an air caster is considered as a means of transporting construction materials at a construction site. However, the air pallet or air caster needs to have a substantially flat road surface. Therefore, it was not possible to use an air pallet or an air caster at a construction site where a mountain shape and a valley shape are repeatedly continuous, such as a roof.

Therefore, an object of the present invention is that when a long building plate material formed by a molding machine at a construction site such as a roof is transported near an unthatched portion of a roof, it can be transported with an extremely small force, and is simple and easy. It is an object of the present invention to provide a construction transport device which can be quickly transported, can be arranged in a state where a folded plate roof plate can be easily constructed at a construction position, and can have an extremely simple structure.

The construction transport device according to claim 1, wherein the construction transport device according to claim 1 is provided with a fixed table provided on the upper surface side of the transport base and on which the building materials can be placed. By doing so, the above problem was solved. In the description of any one of claims 1, 2, 3 or 4, the invention of claim 5 solves the above-mentioned problem by using a construction transport device in which the transport base is formed in an oval shape . .. In the description of any one of claims 1, 2, 3, 4 or 5, the invention of claim 6 has both rising side surfaces of the transport rail outward in the width direction of the flat road surface toward the upper end. The above-mentioned problems have been solved by using a construction transport device that serves as an expanding inclined surface .

The invention of claim 7 is the above-mentioned by making the invention of claim 7 a construction transport device provided with a handle in the transport base in the description of any one of claims 1, 2, 3, 4, 5 or 6. Solved the problem. According to the invention of claim 8, in the construction transport device according to any one of claims 1, 2, 3, 4, 5, 6 or 7, a motor unit is provided as a power source for driving the ventilation mechanism unit. However, the above problem was solved by using a construction transport device installed on the transport base as the power supply section of the motor section .

According to the invention of claim 9, in the construction transport device according to any one of claims 1, 2, 3, 4, 5, 6 or 7 , a motor unit is provided as a power source for driving the ventilation mechanism unit. However, the above problem was solved by making the power supply unit of the motor unit a construction transfer device installed outside the transfer base and connected to the motor unit by an electric cable.

The engine is used as a power source for driving the blower mechanism portion in the construction transfer device according to any one of claims 1, 2, 3, 4, 5, 6 or 7 , according to the invention of claim 10. The above-mentioned problems have been solved by using a construction transport device.

According to the first aspect of the present invention, the transport body is provided with a blower mechanism unit, a power supply unit, and a telescopic skirt portion, and is floatable and movable on the transport rail by the transport body itself. Therefore, the transport body can move on the transport rail with almost no resistance, and the worker who transports a long object such as roof construction can easily perform the work of installing it in a predetermined position with a very small number of workers. It can be done easily.

In particular, by arranging a plurality of transport rails in parallel, installing a transport body on each transport body, and mounting a building material such as a long roof plate on the plurality of transport bodies, a plurality of transports are carried. Only by moving one of the bodies by the worker, the weight of the building material is related to the other body, so all the bodies can be moved at the same time, and the building material can be transported. It plays.

The use of an air pallet or an air caster is considered as a means for transporting construction materials at a construction site, but the air pallet or the air caster needs to have a substantially flat road surface. Therefore, it was not possible to use an air pallet or an air caster at a construction site where a mountain shape and a valley shape are repeatedly continuous, such as a roof. Therefore, in the present invention, the transport rail 7 is used together with the transport body A, and the transport body A is moved via the transport rail 7. As a result, it is possible to smoothly and quietly transport the roof at the roof construction site where the unevenness is continuous.

Further, the telescopic skirt portion of the transport body has a larger front-rear direction than the width direction, and the transport rail has rising side surfaces formed on both sides of the flat road surface in the width direction. Since the width direction of the transport body is set to fit, the transport body can move on the transport rail without tilting in the front-rear direction.

Further, in the invention of claim 1, since the air escape hole is formed near the end of the transport rail, the air in the telescopic skirt portion is released when the transport body reaches the position of the air escape hole. , The carrier becomes inoperable. As a result, when the carrier accidentally goes into a runaway state, the carrier can be automatically stopped to prevent the carrier from falling from the transport rail due to the runaway. Further, the carrier can be stopped at a desired position by determining the position at which the carrier stops in advance and forming an air escape hole at this position.

In the invention of claim 2, the transport base is provided with a slide table that slides in the front-rear direction along the longitudinal direction of the transport base, and the slide table is provided with a mounting surface for construction materials, and the mounting surface is provided. The structure that allows the surface to project beyond the tip of the transport base makes it easy to place the construction material placed on the transport body in a predetermined position when used at a construction site. In the invention of claim 3, the slide table is provided with an elastic member that always returns to the initial position, so that after installing the construction material in a predetermined position, the carrier is returned to the original position and the next construction material is specified. It can be done efficiently when repeating the work of transporting to the position.

In the invention of claim 4, since the fixed table provided on the upper surface side of the transport base and on which the building material can be placed is provided, the blower mechanism unit, the power supply unit, and the like are not interfered with each other. Building materials can be placed on the transport base, and the mounting space can be effectively used.

In the invention of claim 5, since the transport base is formed in an oval shape, when the transport body comes into contact with the compatible ascending side surface of the transport rail, it is less likely to receive an impact and smooth movement can be maintained. In the invention of claim 6, both the rising side surfaces of the transport rail are inclined surfaces that expand outward in the width direction of the flat road surface toward the upper end, so that air ejected from below the transport body is discharged from the transport rail. The slanted shape can be smoothly sent out from the ascending side surface to the outside of the transport rail, and the movement of the transport body can be further improved. In the invention of claim 7, since the transport base is provided with the handle, the operability of the worker can be made extremely good.

In the invention of claim 8, the construction conveyor of the present invention can be self-propelled by having a motor unit as a power source for driving the ventilation mechanism unit and installing the power supply unit of the motor unit on the transport base. .. In the invention of claim 9, a motor unit is provided as a power source for driving the ventilation mechanism unit, and the power supply unit of the motor unit is installed outside the transport base and connected to the motor unit by an electric cable. , The loading space of the transport base is widened, and more building materials can be placed. In the invention of claim 10, since the engine is used as the power source for driving the blower mechanism unit, the power supply unit becomes unnecessary and the load capacity can be increased.

Hereinafter, the present invention will be described with reference to the drawings. The folded plate transport receiver of the present invention is a building device for transporting a building material 9 used as a roof plate material to an installation position at a roof construction site of a construction site (see FIGS. 7 to 9). The building material 9 transported by the construction transport device of the present invention is, for example, a folded plate type metal member, specifically a roof plate material, which is long in the longitudinal direction and is generally about. It is about 50 m to about 100 m.

As shown in FIGS. 8 and 9, the building material 9 such as a folded plate roof plate has a valley-shaped main plate 91 bent in a bottomed V shape in the width direction, and has a flat bottom surface portion. Inclined side surface portions 91b and 91b are formed on both sides of the 91a in the width direction. Bending portions 92 and 92 for connection are formed on both sides of the valley-shaped main plate 91 having a bottomed V shape in the width direction.

As for the connecting bent portions 92 and 92, in the steel type building material 9, one of the connecting bent portions 92 is the lower portion 92a and the other is the upper portion 92b. Further, as the building material 9, although not particularly shown, there is a fitting type, and the connecting bent portions 92 and 92 have a cap material added as a separate member to the connecting bent portions 92 and 92. There is a structure that fits.

As shown in FIGS. 1 and 2, the construction transport device in the present invention includes a transport body A and a transport rail 7. Further, the transport body A mainly includes a transport base 1, a blower mechanism section 2, a power supply section 3, and a telescopic skirt section 4. The transport base 1 is an oval (including an ellipse) or rectangular plate-shaped member [see FIG. 2B]. The transport base 1 is a portion on which the building material 9 is placed, and has strength and rigidity sufficient to withstand the weight thereof. The transport base 1 is made of wood, synthetic resin, metal, or the like, but is preferably lightweight.

The blower mechanism portion 2 serves to send air to the telescopic skirt portion 4 [see FIGS. 2 (C) and 2 (D)]. The blower mechanism portion 2 has substantially the same structure as a general air blower, and includes a blower portion 21 and a power source 22 for driving the blower portion 21. As the blower unit 21, a substantially general blower is often used. The blower portion 21 has substantially the same structure as a general air blower, and is equipped with an impeller inside.

A motor unit 22a and an engine 22b exist as a power source 22 for driving the blower unit 21. In the embodiment in which the motor unit 22a is used, the power supply unit 3 for supplying electricity to the motor unit 22a is provided. In many of the blower mechanism portions 2, the blower portion 21 and the motor portion 22a have an integrated body. The blower mechanism unit 2 and the power supply unit 3 of the motor unit 22a thereof are installed and fixed on the transport base 1 [see FIGS. 1 (A) and 1 (B)].

As the power supply unit 3, a substantially general small generator is often used. The power supply unit 3 has a structure that can be detached from the ventilation mechanism unit 2 of the transport base 1 so that the power supply unit 3 can be replaced [see FIG. 1 (B)]. By installing the power supply unit 3 on the transport base 1, the operation becomes easy to handle. Further, the power supply unit 3 is not installed on the transport base 1, but is installed at a predetermined position on the work site, is connected to the motor unit 22a of the ventilation mechanism unit 2 by the power cable 31, and the ventilation mechanism unit 2 is driven. [See FIG. 11 (A)].

The type in which the power supply unit 3 is not installed on the transport base 1 has an advantage that the weight of the transport body A itself can be reduced and the load capacity of the building material 9 to be transported can be increased. An engine 22b such as gasoline or diesel may be used as the power source 22 for driving the blower mechanism 2 [see FIG. 11 (B)]. When the engine 22b is used, the output shaft of the engine is directly connected to the ventilation mechanism unit 2 to blow air. When the engine 22b is used, the power supply unit 3 becomes unnecessary.

The blower mechanism portion 2 communicates with the telescopic skirt portion 4 mounted on the lower surface side of the transport base 1 by a blower pipe 23 penetrating the transport base 1. Then, the air generated by the blower mechanism portion 2 is supplied to the telescopic skirt portion 4. The telescopic skirt portion 4 is mounted as a substantially floating ring on the lower surface side of the transport base 1 [see FIGS. 1 (C) and 2 (B) to (D)].

It is attached to the lower surface side of the transport base 1 by a strip-shaped fixing member 42 that is long so as to pass through the center in the front-rear direction and the width direction of the telescopic skirt portion 4, and is tubular along the outer peripheral direction of the transport base 1. It was formed in. It is configured so that air collects inside the telescopic skirt portion 4, and when the telescopic skirt portion 4 is filled with air, it becomes a floating ring having a substantially oval shape or a “0” shape (see FIGS. 1, 2, etc.). ).

By storing the air supplied from the blower mechanism portion 2 via the blower pipe 23 inside the tubular telescopic skirt portion 4, the skirt portion 4 is deformed into a floating ring shape from the deflated state. A plurality of air blowing holes 41 are formed in the tubular telescopic skirt portion 4 [see FIGS. 1 (C) and 2 (B) to (D)].

The air blowing hole 41 is formed on the inner peripheral side of the telescopic skirt portion 4, and air is collected in the gap portion surrounded by the telescopic skirt portion 4, and the carrier A can be floated by the air. Further, as another embodiment of the telescopic skirt portion 4, two or more circular floating ring-shaped ones may be arranged along the longitudinal direction on the lower surface side of the transport base 1 [see FIG. 11 (C)). ].

The transport rail 7 serves to guide the transport body A in a predetermined direction. Therefore, the transport rail 7 may be simply referred to as a rail. The transport rail 7 is composed of a flat road surface 71 and a rising side surface 72, and the flat road surface 71 is a substantially uniform flat surface. Rising side surfaces 72, 72 that are symmetrical to each other are formed on both sides of the flat road surface 71 in the width direction [FIGS. 1 (A), (C), (D), 2 (C), (D), FIG. 3 reference〕.

The rising side surface 72 rises and is formed on the upper side of the flat road surface 71. The rising side surface 72 is formed in an inclined shape so as to expand outward from each other from the lower end, which is the bending point with the flat road surface 71, toward the upper side [FIGS. 1 (A), 1 (B), See Figure 3]. Further, the compatible ascending side surfaces 72 and 72 may be formed at right angles to the flat road surface 71. The transport rail 7 is formed as a long length, and one of the transport rails 7 is used as it is. Further, a plurality of transport rails 7, 7, ... may be connected in the longitudinal direction for use.

The length dimension of the transport base 1 in the longitudinal direction is formed to be larger than the width dimension of the transport rail 7. As a result, the transport base 1 can be reciprocated accurately along the longitudinal direction of the transport rail 7 with its longitudinal direction in the front-rear direction, and can move in a stable state without swinging along the longitudinal direction of the transport base 1. Will be. An upper part 5 is provided on the transport base 1.

The upper part 5 is a part of equipment that mainly serves as a loading. A specific example of the upper part 5 will be described. A slide table 51 that slides in the front-rear direction along the longitudinal direction of the transport base 1 is provided. The slide table 51 is provided with a mounting surface 51a for construction materials, and the mounting surface 51a is a place on which the building material 9 is placed. A mounting holding plate 51b that is inclined outward and upward is formed at the front end of the mounting surface 51a described above [FIGS. 1 (A), (B), 2 (C), (D)). reference〕.

The mounting holding plate 51b holds the building material 9 loaded on the mounting surface 51a, and serves to maintain a stable mounting state. The slide table 51 is installed on the transport base 1 via the slide rail member 52, and is installed so as to be reciprocally movable along the longitudinal direction of the transport base 1. Specifically, the slide table 51 is installed on the front side of the transport base 1 [see FIGS. 1 (A), (B), 2 (A), (C), (D)]. Further, the slide table 51 is provided with an elastic member 52a that always returns to the initial position, and is set to return to the original position after sliding. Specifically, a coil spring is used for the elastic member 52a [see FIGS. 2 (A) and 2 (C)].

Further, the transport base 1 is provided with a power supply table 53 in which a power supply unit 3 for driving the blower mechanism unit 2 is installed [FIGS. 1 (A) to (C), FIGS. 2 (A), See (C), (D), etc.]. The power supply table 53 is configured to be slidable in the longitudinal direction on the transport base 1, and is installed on the transport base 1 via a slide member 54. The power supply unit 3 generates electricity and is a generator using a battery or an engine. The power supply table 53 has a slide configuration in which the transport base 1 can be reciprocated in the longitudinal direction.

In the power supply table 53, the position of the center of gravity G of the entire transport body A changes depending on whether the building material 9 is placed on the transport base 1 or not. At this time, the power supply table 53 is used for the power supply. By moving the table 53 in the longitudinal direction of the transport base 1, the position where the weight of the power supply unit 3 is applied changes, and as a result, the position of the center of gravity G of the entire transport body A can be changed [FIG. 6 (A). ), (B)].

The power table 53 is provided with a fixing device so as to slide and stay in a predetermined position, and may be fixed in a predetermined position. Specifically, although not shown in particular, lock bolts and the like are used. A handle 11 may be attached to the transport base 1. The handle 11 is used by an operator to move the transport body A by hand, or by connecting the handles 11 of the plurality of transport bodies A, A, ... To move the plurality of transport bodies A, A, ... At the same time. You can also do it.

Next, the stop mechanism at the terminal portion of the transport rail 7 of the transport body A in the present invention will be described with reference to FIGS. 4 and 5. An air escape hole 73 is formed at the terminal position of the transport rail 7 (see FIG. 3). The air escape hole 73 is formed on the flat road surface 71. Then, when the transport body A moves along the transport rail 7 and the transport body A reaches the position of the air escape hole 73, the air (air) discharged from the air blowout hole 41 of the telescopic skirt portion 4 is air. It is escaped from the relief hole 73 [see FIGS. 4 (C) and 5 (B)].

As a result, a large amount of air in the telescopic skirt portion 4 is discharged, and the pressure in the telescopic skirt portion 4 is sharply reduced. As a result, the telescopic skirt portion 4 is narrowed and the carrier A cannot be floated [see FIG. 4 (C)]. As a result, the transfer body A cannot be moved, and the transfer body A is stopped to move [see FIGS. 4 (C) and 5 (B)]. Since the air release hole 73 is provided in the transfer rail 7, when the transfer body A reaches the position of the air release hole 37, the vehicle cannot travel.

Then, when the transport body A is erroneously put into a runaway state, the transport body A is automatically or forcibly stopped, and it is possible to prevent the transport body A from falling from the transport rail 7 due to the runaway. Further, by determining in advance the position where the transport body A stops and forming the air escape hole 73 at this position, the transport body A can be stopped at a desired position.

Since a plurality of transfer rails 7 are often used by being connected in the longitudinal direction, air escape holes 73 are not formed in all the transfer rails 7, and a plurality of connected transfer rails 7, 7, ... The air escape hole 73 is formed only in the transport rail 7 which is finally located in the above. The shape of the air escape hole 73 is an oval shape, a circular shape, a rectangular shape, or the like. By forming the air escape hole 73 at the final position of the transport rail 7, even if the transport body A accidentally runs out of control, it can always stop at the final position of the transport body A, ensuring safety. ..

FIG. 10 is another embodiment of the carrier A of the present invention. A fixed table 55 is installed on the transport base 1 of the transport body A as an upper mounting portion 5. The fixed table 55 is provided with four legs 55b, 55b ... On a rectangular mounting top plate portion 55a. The fixed table 55 is provided so as to be located above the blower mechanism unit 2 and the power supply unit 3, and the lower ends of the leg portions 55b, 55b, ... Are fixed on the transport base 1. The fixed table 55 can obtain an effective space by the mounting top plate portion 55a.

Next, the use of the present invention will be described. First, the roof construction section B is set at the roof construction site. The roof construction portion B refers to a portion where a roof is constructed at a construction site of a building structure. In the roof construction portion B, a plurality of structural materials 81 such as purlins and furring strips constituting the base portion 8 of the roof of the built structure are juxtaposed (see FIGS. 7 and 8). Then, a plurality of receiving metal fittings 82, 82, ... Are juxtaposed and fixed to each structural member 81 at predetermined intervals along the longitudinal direction thereof.

Further, a molding machine 100 that rolls the building material 9 is arranged according to the construction position of the structural material 81 (see FIG. 7). A transport receiver (not shown) is installed along the extrusion direction of the building material 9 by the molding machine 100. Then, 4 to 5 building materials 9 extruded while being molded from the molding machine 100 are made, and first, the first part of the folded plate roof is constructed by 4 to 5 building materials 9, 9, ... [ See FIG. 8 (A)].

Then, the transport rail 7 is installed in the portion where the construction by the building material 9 is completed [see FIG. 8 (B)]. A plurality of transport rails 7 are installed in the longitudinal direction of the building material 9 so as to be orthogonal to the longitudinal direction of the building material 9 so as to be parallel to the building material 9 and at substantially equal intervals. The transport rail 7 is arranged up to the vicinity of the position where the building material 9 to be transported is to be installed and constructed [see FIG. 9 (A)]. Next, the transport body A is installed on the plurality of transport rails 7, 7, ... [See FIG. 8 (C)].

Next, the blower mechanism unit 2 of each carrier A is started. When the blower mechanism portion 2 starts, air is sent from the blower portion 21 into the telescopic skirt portion 4. As a result, air collects inside the telescopic skirt portion 4, air is ejected from the air blowing hole 41, the carrier A floats from the flat road surface 71 of the carrier rail 7, and the carrier A floats on the carrier rail 7. It becomes a state where it can move in the front-back direction.

Then, the building materials 9 to be installed are placed on the slide tables 51, 51, ... Of the plurality of transport bodies A, A, ... Arranged in parallel, and the plurality of transport bodies A, A, ... Move at the same time. The movement of each carrier A is performed by a worker. As a method of moving, if a worker pushes one of all the transport bodies A, A, ... In the moving direction, the building material 9 installed on all the transport bodies A, A, ... , A, ... Serves as a connecting member, and all the carriers A, A, ... Can move at the same time or stop at the same time (see FIG. 7).

When the plurality of transport bodies A, A, ... On which the building material 9 is placed reach the position where the building material 9 is installed and constructed, the movement of the plurality of transport bodies A is stopped and the plurality of transport bodies A are placed on the transport body A. The building material 9 is unloaded from the carrier A, and the upper portion 92b of the building material 9 conveyed by the carrier A is placed between the receiving metal fittings 82 and 82 while being superimposed [see FIG. 9 (C)]. ..

Here, in the case where the slide table 51 is provided on the upper mounting portion 5, when the transport body A reaches a predetermined transport position, the slide table 51 is pushed out to the front side of the transport body A, and the building material 9 is used. It is positioned on a predetermined installation position, and the building material 9 is lifted from the slide table 51. Then, the slide table 51 with no load is returned to the original position by the elastic member 52a, and when the building material 9 is lowered as it is, it can be installed at the installation position [see FIG. 9B]. This is repeated in sequence to construct a folded plate roof.

Further, by providing the air escape hole 73 at the terminal end of the transfer rail 7 located at the end of the plurality of connected transfer rails 7, the transfer body A automatically stops when the position of the air escape hole 73 is reached. Further, the air escape hole 73 serves as a stopper when the carrier A accidentally runs out of control.

In the present invention, as described above, the transport body A transports the construction material 9 such as the folded plate roof plate while floating the flat road surface. Then, in order to transport the roof plate material to a predetermined construction position at a site such as a folded plate roof in which mountain shapes and valley shapes are alternately continuous, a transport rail 7 is provided, and a transport body A is placed on the transport rail 7.
