In the figure, reference numeral 1 denotes a transport cart, which is formed by combining a cart 2 and a support frame 3. As shown in FIGS. 3 and 4, the carriage 2 has four universal casters 5 attached to the bottom of the carriage body 4, and support frame receiving portions 6 formed of square pipes on both front and rear sides face each other upward. Two are attached diagonally so that Furthermore, one stopper member 30 </ b> A is attached to the center bottom of the carriage body 4.

As shown in FIG. 5, the support frame 3 is provided with a loading base portion 8 in the lateral direction, and a building material side support portion 10 that supports the side surface of the building material such as gypsum board in the vertical direction can be opened and closed by a hinge 12. It has a connected structure. The two L-shaped frames 11 of the side surface L shape combining the loading base portion 8 and the building material side surface support portion 10 connect the upper portions of the left and right building material side surface support portions 10 with hinges 13 so that they can be opened and closed. When opened, the side surfaces of the two building material side support portions 10 have a reverse side V shape. As shown in FIG. 1, the opening angle of the inverted V-shape of both the building material side surface support portions 10 is about 7 degrees so that the upper portion does not hit the building base material 20 such as gypsum board on the left and right loading base portions 8. Is set.

The stacking base portion 8 is a square pipe and is formed in a square frame shape, and a rubber mat 16 is mounted on the front and rear sides. Stoppers 18 are attached to the lateral ends of the stacking base portions 8 on both sides.

Further, as shown in FIG. 1, an angle adjusting portion 19 formed of a square pipe is attached to the bottom portion of the stacking base portion 8, and the support frame 3 is attached to the carriage 2 so that the lower portion of the building material side support portion 10 is received by the support frame. When inserted into the part 6, the angle adjusting part 19 comes into contact with the carriage main body 4. As a result, the opening angle between the loading base portion 8 and the building material side surface support portion 10 is 90 degrees. In this state, the width on the left and the right is, for example, about 660 cm, and is formed narrower than the entrance width of the room door, which is 700 cm.

As shown in FIG. 6, the support frame 3 folds the left and right L-shaped frames 11 during storage and transportation, folds the loading base portion 8 in the building material side support portion 10 in the direction of the arrow, and supports the building material side surface support of the L shape frame 11. The truck 10 is brought into contact with the unit 10 to be in a compact state, and the carriage 2 is transported to the site as it is.

When the stacking base portion 8 is spread on the upper surface of the cart body 4, the angle adjusting portion 19 comes into contact and becomes a right angle.

For example, when a building material 20 such as a plaster board is carried into each room of an apartment under construction, the building material 20 taken from the intake port is placed on the left and right loading base portions 8 of the transport carriage 1 with a balance between left and right and front and rear. Then, it is fixed with a strapping belt 21. Thereafter, the floor surface 26 of the hallway is transported from behind the transport cart 1 by hand, and is carried into the room from the opening of the door mounting portion of the room under construction.

Since the opening width of the door mounting portion of the room is about 700 cm and the width of the transport carriage 1 is made to be about 660 cm narrower than this, the transport carriage 1 loaded with a large amount of building material 20 can easily pass. It is possible to improve the workability by 5 times or more compared to the work that has been carried into the room by carrying several sheets at a time, and it is possible to shorten the time for the carry-in work and reduce the fatigue of the operator.

Next, the case where it takes in the 2nd floor of buildings 23, such as a condominium and an apartment, is explained. As shown in FIG. 7, an intake stage 25 is attached in front of the intake port 24 of the building 23, and two concave rails 27 are laid on the floor surface 26 on the upper and second floors. The concave rail 27 has a structure in which the inner side of the building is open and is closed by providing a tire stopper at the front end side of the outer side. Between the left and right concave rails 27, as shown in FIG. Is provided between the concave rails 27 along the same.

The stopper mounting rail 28 is formed of a square pipe as shown in FIG. 9, and the other stopper member 30B is mounted on the top thereof. A U-shaped groove 31 is formed on the upper side surface of the stopper member 30B, and a U-shaped holding metal fitting 32 formed of a spring material is inserted therein. The stopper member 30B can be adjusted in its mounting position on the stopper mounting rail 28 with a tightening knob 33.

One stopper member 30A protrudes downward from the center of the bottom surface of the cart body 4A. The stopper member 30A has a structure in which a cylindrical body 36 is fixed to a bracket 35. The cylindrical body 36 is fitted to the U-shaped holding bracket 32 of the other stopper member 30B, so that the transport carriage 1 is attached to the stopper. The rail 28 is locked and fixed.

The transport cart 1 having the above-described configuration is moved to the tip side of the concave rail 27, and one stopper member 30A of the transport cart 1 and the other stopper member 30B of the stopper mounting rail 28 are fitted and locked. In this state, as shown in FIG. 7, a building material 20 such as a plasterboard that has been transported by being bundled by several tens of trucks is lifted by the tow truck 38 and suspended on the transport carriage 1 and placed on the left and right stacking base portions 8. To do.

At this time, if it is not horizontally suspended, the balance may be lost and the wheel may be removed. However, since the carriage 1 is fixed to the mounting rail 28 by the stopper 30, the wheel can be prevented from being removed and stably loaded.

Next, when the transport carriage 1 is pushed by hand and the stopper 30 is released, it travels on the concave rail 27 and transports it into the building 23 and travels on the floor surface 26 as it is from the opened end. The carriage 1 can be carried in any direction because the free casters 5 are attached to the four corners. When the building material 20 comes to the front of the room where the building material 20 is attached to the wall in this way, it is carried into the room from the opening of the door attachment part of the room.

For this reason, the worker is freed from heavy labor, has little fatigue, and can maintain the willingness to work in the next process. As a result, the construction period can be shortened as a whole, the construction cost can be reduced, and the safety of the working environment can be improved.

FIG. 10 shows a transport cart 1 according to another embodiment of the present invention. In this configuration, the extension base portion 40 is attached to the front and rear of the stacking base portion 8 so as to be extendable and detachable. The extension base portion 40 is obtained by attaching two round pipes 42 to both ends of a square pipe 41 in a plane U shape and attaching a rubber mat 16 on the square pipe 41. The round pipe 42 is inserted in front of and behind the square pipe constituting the stacking base portion 8 and fixed by a pipe fixture 43 with a predetermined length.

This is suitable for transporting long scaffolds because the area of the loading base portion 8 is enlarged, and when storing, the loading base portion 8 containing the support frame 3 and the extension base portion 40 as shown in FIG. It becomes compact by folding.

In the above description, the building material 20 such as a plaster board is shown in the building 23. However, when the building material 20 is brought into the construction site in the back of a narrow road where the truck on the side of the roadway cannot enter, the concave rail 27 is provided on the road. You may make it lay and carry in. In this case, the concave rail 27 may be curved by providing a radius. The building material 20 to be transported is not limited to gypsum board, but can be widely applied to transport of lightweight concrete panels, control panels, bundled small diameter pipes, and the like. It can also be used when parts, products, or agricultural products are transported not only at the construction site but also within the factory.
