Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pedestal for placing plywood, ALC, concrete plate or the like away from the ground or floor surface at a construction site or the like. It relates to a prefabricated wheel to be used.

[0002]

2. Description of the Related Art Plate materials such as plywood, ALC, and concrete plates as building materials are stored in a stacked state when stored at a building site before use, but are directly mounted on the ground or floor. If it is placed, troubles such as absorption of moisture and dirt will occur, so generally two sleeper-shaped pillar members called circles are placed in parallel on the ground or the like, and a plate material is laminated thereon. It is mounted. However, since this columnar member is made of wood or ALC, it is heavy, and it is difficult to easily move the columnar member when moving, and there is a problem that workability is extremely poor.

[0003]

In view of the above, conventionally, a synthetic resin cycle that can be reduced in weight has been disclosed in Utility Model Registration No. 25776.
No. 43, for example. This cycle is made of a synthetic resin strip formed into a corrugated shape, and is placed on a ground or the like in a state where its plane is set upright, and is used as a platform for building plate materials. However, although this cycle is lighter and more convenient to use than conventional columnar members, in order to use a cycle that fits the size of the plate material to be placed, it must be of various widths and heights. Need to make
The problem of increased manufacturing costs was met.

[0004] In other words, when building boards are stacked and placed on the ground or floor, the wood used for the building need only be approximately the same length as the width of the wood. If the width is longer than the width of, the end of the tree protrudes from under the plate and becomes an obstacle. Also, if the length of the wood is extremely short compared to the width of the wood, the mounting condition of the wood will be unstable, so use a wood that has a length corresponding to the width of the wood used. However, there are various widths of the building boards, and if various lengths of wood are manufactured in accordance with the width, the cost of molds and the like will increase, and the manufacturing cost will increase. There was a problem that we had to buy various lengths of wood.

[0005] The present invention has been made in view of the above points, and an object of the present invention is to provide an assembling cycle tree which is lightweight, can be freely changed in length, and can be used conveniently.

[0006]

In order to achieve the above-mentioned object, the present invention provides a prefabricated cycle board which is formed by combining a plurality of component pieces, and the component pieces are provided on one side. A concave portion is formed in a shape having a convex surface portion provided on the other surface side, a fitting concave portion is provided at one end on both sides of the concave portion with the same cross-sectional shape in the vertical direction, and a fitting concave portion is provided on the other of the two side ends. A fitting convex portion that can be fitted to is provided with the same cross-sectional shape in the vertical direction,
The plurality of component pieces are arranged side by side with every other turned upside down, and the fitting concave portion and the fitting convex portion of each adjacently facing component piece are fitted and connected. I do. Here, the planar shape of the component piece can be formed in a semi-cylindrical shape, an arc shape, a trapezoidal shape, or the like.

[0007]

In the assembly type wheel assembly having such a configuration, an arbitrary number of component pieces are arranged side by side with every other being turned upside down, and the fitting recesses of the adjacent opposing component pieces are arranged. The fitting protrusions are fitted to the fittings to assemble a cycle of any length. Basically, this assembling cycle is manufactured by manufacturing a large number of one type of component pieces and combining the component pieces. For example, when the component pieces are molded with synthetic resin, only small component pieces are used. Can be manufactured inexpensively, including the mold manufacturing cost. In addition, at the time of use, since the number of component pieces to be connected can be changed arbitrarily and the length of the cycle can be changed arbitrarily, the user can appropriately change the length of the plate at the site according to the size of the plate material to be put on Since a wheelchair of various lengths can be assembled and can be disassembled and transported when moving, it is easy to move.

In the case where two types of component pieces, that is, a component piece having a low height and a component piece having a high height, are manufactured, a form in which these two types of component pieces are stacked vertically is arranged side by side.
The configuration in which the lower component is located on the upper side and the configuration in which the higher component is located on the upper side are alternately arranged, and the respective configuration pieces are arranged. By fitting the parts, it is possible to assemble a cycle having a height obtained by adding the heights of the two types of component pieces. Therefore, when two types of component pieces having different heights are manufactured, it is possible to assemble a cycle of component pieces of each height, as well as a height obtained by adding the heights of the two types of component pieces. Cycles can also be assembled and formed.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a perspective view of the assembled assembled wheel, and FIG. 2 shows a front view (a), a plan view (b), a rear view (c), and a side view (d) of the component piece alone. I have. As shown in FIG. 2, the assembly type shoe is formed by connecting a plurality of component pieces 1, and the component piece 1 is basically formed into a shape obtained by bending a flat plate into an arc shape in plan view. A fitting concave portion 2 and a fitting convex portion 3 corresponding to the fitting concave portion 2 are provided at both end portions thereof.

[0010] That is, the main body of the component piece 1 has a semi-cylindrical shape obtained by cutting a cylinder of an arbitrary size vertically at the center of its plane, and has a semi-cylindrical concave surface portion 4 on the front side. Then, it is formed to have a semi-cylindrical convex surface portion 5 on the back side. Both end portions of the main body of the component piece 1, that is, both end portions of the concave surface portion 4 form flat surfaces 6, 7 extending vertically to the front side, and the fitting concave portion 2 and the fitting convex portion 3 The flat surfaces 6, 7 on the side have the same cross section in the vertical direction. The fitting concave portion 2 is formed in a dovetail shape wider than the opening, and the fitting convex portion 3 is formed in a shape that can fit tightly into the fitting concave portion 2. That is,
The fitting convex portion 3 is formed by extending a cylindrical portion having an outer diameter larger than the thickness of the plate-shaped portion at the tip of the plate-shaped portion. It is formed as a recess.

The component 1 having such a structure can be easily formed by injection molding or the like using a general-purpose synthetic resin material. Since it is possible to assemble and form only the component piece 1, the manufacturing cost including the cost of the molding die is not so required. In addition, the component pieces 1 can be mass-produced using the same mold injection molding machine, and the manufacturing cost can be further reduced.

The component 1 is vertically symmetrical with respect to the central horizontal line in the front view (a). The fact that the component pieces 1 are formed vertically symmetrically about the central horizontal line is important when the component pieces 1 are combined to form a cycle, and the component pieces 1 are formed vertically symmetrically about the central horizontal line. This makes it possible to assemble the cycle while alternately inverting the component pieces 1 having the same shape up and down.

That is, when assembling a cycle, first,
A number of component pieces 1 are arranged side by side, and every other component piece 1 is turned upside down. That is, the component piece 1 in which the concave portion 4 faces the front.
And the component pieces 1 with the convex portions 5 facing the front are alternately arranged,
The fitting concave portion 2 of each component piece 1 and the fitting convex portion 3 of the adjacent component piece 1 are arranged so as to face each other. And
The fitting concave portion 2 of each component piece 1 is fitted to the fitting convex portion 3 of another adjacent component piece 1. This completes the cycle as shown in FIG. The number of the constituent pieces 1 to be combined can be arbitrarily determined, and accordingly, a cycle of an arbitrary length can be easily assembled according to the width of a plate material to be actually put on the top. Further, since the above-described assembling is possible even at a construction site, the required number of component pieces 1 can be stacked and carried in a reduced size, for example, so that the wood can be assembled to a required length at the site.

In the assembled cycle, as shown in FIG. 3, a pair of cycles are placed side by side on the ground or floor, and a building plate B is placed thereon. Of course, after use, each component 1 can be disassembled and separated, miniaturized and easily carried.

FIG. 4 shows a perspective view of a doubled woodblock. This cycle is made of a plurality of component pieces 1 as described above.
It is formed by combining 0 horizontally. Each of the constituent pieces 10 has the same structure except that the height of the constituent piece 1 is doubled. That is, the component piece 10 is formed into a shape bent so as to have an arc shape in a plan view, and the fitting concave portion 12 and the fitting convex portion 13 that can be fitted into the fitting concave portion 12 are formed at both end portions. It is provided and configured. The fitting recess 12 is formed in a dovetail shape wider than the opening similarly to the fitting recess 2, and the fitting protrusion 13 is formed at the tip of the plate-like portion similarly to the fitting protrusion 3. A cylindrical portion having an outer diameter larger than the thickness of the plate-like portion is formed so as to extend therefrom, and is formed into a shape capable of being tightly fitted in the fitting concave portion 12.

That is, the fitting concave portion 12 is different only in length from the fitting concave portion 2, and the fitting convex portion 13 is only different in length from the fitting convex portion 3, and has the same sectional shape. are doing. Therefore, the fitting concave portion 12 can be fitted with the fitting convex portion 3, and the fitting concave portion 2 can be fitted with the fitting convex portion 13. Therefore, as shown in FIG. 5, the low-height component pieces 1 and the high-height component pieces 10 are vertically overlapped with each other, and the vertical relation between the adjacent high-height component pieces 1 and 10 is higher. And the case where the component piece 10 is located on the upper side is alternately arranged and connected. Then, when the fitting concave portions and the fitting convex portions on both side ends of the adjacent and opposing constituent pieces 1 and 10 are fitted, as shown in FIG. 5, the height obtained by adding the heights of the constituent pieces 1 and 10 Can be assembled.

As described above, by merely manufacturing two types of component pieces 1 and 10 having different heights, a wheel having the height as shown in FIG. 1 and the height of the component piece 1 as shown in FIG. Height is component piece 1
A zero-height cycle and a height as shown in FIG.
And 10 can be assembled and formed.

Cycles having different heights can be selectively used according to the condition of the ground on which they are placed. For example, when the ground is relatively hard, a cycle combined with component pieces 1 having a low height is used. In the case where the ground is relatively soft and there is a possibility that the cycle will sink into the ground, the tall component piece 10 or the component pieces 1 and 1
Use a zero-cycle. Furthermore, for example, when there is a step on the ground or floor, a high-cycle can be placed at a position with a low step and a low-cycle can be used at a position with a high step.

FIGS. 6 and 7 show examples in which the planar shape of the component piece is changed. The component piece 20 of FIG. 6 is formed in an arc shape whose planar shape is shorter than the semi-cylindrical shape. By thus making the shape in plan view a short arc shape, as shown in FIG.
