Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a reinforcing bar transport device that can easily and simply transport reinforcing bars arranged in a lattice in a construction work site, and a reinforcing bar transport device using the same. It is about the method.

<Conventional technology> Conventionally, there was no rebar transporting device suitable for transporting reinforcing bars arranged in a lattice pattern, so several people carried bundles of reinforcing bars that were carried to predetermined locations using cranes, etc. The reinforcing bars were transported by hand, with workers working in groups to place the reinforcing bars one by one in a predetermined position.

<Problem to be solved by the invention> However, even a 38φ, 12m straight reinforcing bar used in many construction works weighs approximately 100kg.
Because of this, a single reinforcing bar must be transported by as many as 5 to 6 workers, and even if one worker is absent, the small transport and reinforcement work must be interrupted. There was a problem. Furthermore, manually transporting heavy reinforcing bars by workers poses a safety problem, and some kind of improvement has been desired.

The present invention was devised to solve the above-mentioned conventional problems, and provides a reinforcing bar that can easily and safely transport and safely carry heavy reinforcing bars even on reinforcing bars arranged in a lattice pattern. The purpose of the present invention is to provide a transportation device and a transportation method using this transportation device.

<Means for Solving the Problems> In order to achieve the above object, in the present invention, among the reinforcing bars arranged in a lattice pattern, a reinforcing bar between a pair of left and right wheels that is in rolling contact with two mutually parallel reinforcing bars, respectively. A reinforcing bar transporting device includes a frame having an intermediate portion pivoted at a proper position so as to be tiltable back and forth, a reinforcing bar receiver provided at the front end of the frame, and a handle provided at the rear end of the frame. . Further, the present invention is characterized in that the two reinforcing bars transporting devices configured as described above are arranged separated by a predetermined distance to transport the long reinforcing bars.

〈Operation〉 As a result, long and heavy reinforcing bars can be easily and safely transported and placed by a small number of people by rolling the wheels using the previously placed reinforcing bars as rails. That's what I do.

<Example> Examples of the present invention will be described in detail below based on the drawings.

FIG. 1 is a perspective view showing an embodiment of the reinforcing bar transporting device according to the present invention, in which wheels 3, 3 running on the upper surface of vertical reinforcing bars 2, 2 arranged on a reinforcing bar temporary receiving angle 1 are placed at both ends. At the center of the axle 4, which is attached to the
The middle part of the frame 5 is fixed. Here, the vehicle has a cylindrical flat tire 3a having a predetermined width.
and a circular tire 3b with a larger diameter than the flat tire 3a.
The circular tire 3b is integrally fixed to the outside of the flat tire 3a, and both tires 3
A and 3b are rotated together. The outer circumferential surface (running surface) of the flat tire 3a is made of an iron plate or the like, and the circular tire 3b is made of a pneumatic rubber tire as in the case of conventionally known tires.

On the other hand, the frame 5 is composed of a fork 5a extending front and upward from the axle 4, and a lever arm 5b extending rearward and upward from the axle 4,
A handle 6 is attached to the tip (rear end) of this lever arm 5b.
while fixing the lever arm 5b to the fork 5.
It is longer than a.

Further, a reinforcing bar receiver 7 formed of an angle material is fixed near the tip of the fork 5a, so that reinforcing bars can be placed on this reinforcing bar receiver 7.

When transporting, for example, horizontal reinforcing bars 8 that are superimposed on vertical reinforcing bars 2 using the reinforcing bar transporting device configured as described above, the lever arm 5 is used as shown in FIG.
After lifting the fork 5b greatly forward and inserting the tip of the fork 5b under the reinforcing bar 8, the lever arm 5a is rotated in the direction of the arrow in the figure by operating the handle 6, and the reinforcing bar 8 is scooped up with the fork 5b. Then, as shown in FIG. 3, the flat tires 3a of the wheels 3 are brought into contact with the upper surface of the vertical reinforcing bars 2 to a predetermined position. In addition, during this transportation, the wheels 3, 3 mounted on both ends of the axle 4 come into contact with the upper surfaces of the vertical reinforcing bars 2, 2 adjacent to each other, and the height of the handle 6 is adjusted to lift the fork 5b. By adjusting the angle, the weight applied to the handlebar 6 can be reduced by positioning the reinforcing bar receiver 7 directly above the axle 4, thereby maintaining good balance in the left-right and front-back directions even with heavy reinforcing bars. and can be transported safely. For example, when climbing over the horizontal reinforcing bars 8, the circular tire 3b, which is formed to have a larger diameter than the flat tire 3a, comes into contact with the horizontal reinforcing bars 8, 8 as shown on the right side of FIG. Even when the horizontal reinforcing bars 8, 8 are overlapped on the top surface, the reinforcing bar transport device can be easily moved, and after transporting the reinforcing bars to a predetermined position, the handle 6 can be turned wide as shown in Fig. 4. The reinforcing bars 8 placed on the reinforcing bar receiver 7 may be released forward by lifting and rotating.

FIG. 5 shows another embodiment of the present invention, in which circular tires 3b, 3b are integrally fixed on both sides of a flat tire 3a, and a bracket 9 and a frame 5 for supporting an axle are provided. By interposing the swinging mechanism 10 in the horizontal plane between the wheels 3 and 3, the direction of the frame 5 can be easily changed while preventing the wheels 3 from falling off the reinforcing bars 2, 2 due to the circular tires 3b, 3b. I'm trying to make it possible.

FIG. 6 shows a state in which long reinforcing bars are transported according to the second invention, and two reinforcing bars are transported at a predetermined distance apart depending on the length of the reinforcing bars 8 to be transported. By using the device, even long reinforcing bars that are heavy and difficult to handle can be transported stably and easily.

In addition, in order to increase the adaptability to changes in the pitch of the vertical reinforcing bars 2, 2 and to the lap portion, the width of the flat tire 3a should be made wider, for example, about 3 to 4 times the width of the reinforcing bars, or more, and the width of the horizontal reinforcing bars, etc. In order to improve the overcoming performance of the wheels, it is desirable to construct the circular tires 3b, 3b with pneumatic rubber tires or the like, but the specific structure of the wheels 3 is arbitrary. Further, in the embodiment, a fork 5b is provided in front of the reinforcing bar receiver 7 to improve the performance of scooping up reinforcing bars, but the fork 5b may be omitted in some cases.

<Effects of the Invention> As explained above, according to the present invention, even heavy reinforcing bars can be easily and safely transported to a predetermined position by two workers, thereby reducing the burden on the crane. The unloading work, the bundling work, and the small-scale transportation and reinforcement work of reinforcing bars can be performed in parallel, thereby shortening the reinforcement process. Furthermore, since the transport device has a simple structure and is light in weight, it can be easily moved by hand. Furthermore, it is needless to mention in detail that long heavy objects such as reinforcing bars can be easily transported not only on reinforcing bars arranged in a lattice pattern but also on flat ground.
