Description

[Detailed explanation of the invention] A. Purpose of the invention (a) Industrial application field This invention relates to a mobile platform for storing and transporting pipe supports (formwork supports) used at concrete construction sites.

(b) Prior Art Pallets used in aluminum processing factories for storing long aluminum materials are well known. As shown in Figure 5, it is a pallet consisting of a flat floorboard with four pillars attached to the four corners.

(c) Problems to be solved by the invention The conventional pallet for storing long aluminum materials, which are approximately rectangular parallelepiped in shape and have no irregularities on the outside, is replaced by a pipe support S, that is, a lower pipe as shown in Fig. 4. A pipe support (hereinafter referred to as a "support") has a complex configuration and shape, with square plates at one end of the upper and lower pipes, and a threaded pipe 21 in the middle. ).
There are many problems with using it as is for storage and transportation. First of all, in the conventional pallet, the flat floorboard and the cargo are in close contact with each other, so it is not possible to insert the claw of a forklift between them. Therefore, there is a drawback in that it is not possible to separate and take out only the support for the cargo from the pallet. Therefore, the first problem to be solved is to allow the claws of the forklift to fit between the pallet pedestal and the storage support.
b.Next, in the case of conventional pallets with flat floor plates, when only the supports are hoisted by a crane with wires attached, the pallet pedestal is flat and the supports are stored along it, so when a load is applied, the wires are The state becomes a U-shaped state. At that time, the square-shaped loads are squeezed into a U-shape, causing the loaded positions of the supports to shift and become staggered, or the supports to be tilted because they cannot maintain their horizontal position. As a result, the upper tube inserted into the lower tube of the support may come off and fall outside. Furthermore, if the pedestal is flat, it takes an immeasurable amount of mental and physical effort to organize not only the first tier of cargo but also each tier of cargo in an orderly manner. In order to save such labor and solve the above problem, the second problem to be solved is to make it possible to stack supports on pallets so that they are stacked in a U-shape from the beginning. cThirdly, the pallet of the conventional technology only receives the load using four supports, and while it is not a big problem if the load is light such as aluminum, if 50 supports are stored, the weight will be approximately 1
If there are only four supports, the supports will easily open outward and be damaged due to the weight of the supports, and it is dangerous to store the supports stacked on pallets. Therefore, the third problem to be solved is to ensure that the strength of the pallet columns is maintained even when the load of the supports is increased. dFinally, the conventional pallet has a plate-shaped pedestal, which makes it heavy, and there are only places to hold the pallet at both ends.
The disadvantage is that it must be carried by people. Therefore, the fourth problem to be solved is to reduce the weight of the pedestal as much as possible while maintaining its strength so that it can be easily carried by one person when empty.

B. Structure of the invention (a) Means for solving the problems The structure of the invention will be explained based on the drawings. 1st
The figure is a perspective view of the support pallet according to the present invention, FIG. 2 is a plan view of the bottom frame, and FIG. 3 is a perspective view of one support. First of all, as shown in Fig. 2, the four sides of two horizontal frames a, two vertical frames b, and two vertical bars c supporting them are made of a rectangular bottom frame made of steel pipes. 1. Round holes d are provided at the four corners of the bottom frame 1, and a small protrusion e is attached to the center of the upper surface of the horizontal frame a. Next, as shown in Fig. 1, the round hole d
Insert the four supports 2, 3, 4, and 5 into the bottom frame 1.
Install it vertically. Supports 2 to 5 are steel pipes with the same shape, so their configuration is similar to that of the third model.
The explanation will be based on the support column 2 shown in the figure. The main body of the support column 2 has an outer diameter slightly smaller than the round hole d provided in the bottom frame 1, and the lower end portion 2' of this main body is connected to the bottom frame 1.
It is thicker than the round hole d, and is configured in the shape of a bowl facing down. Next, as shown in FIG. 1, the bottom surface of a U-shaped steel pipe 6 with a clamp, which has cylindrical clamps m attached to one opposing support pillar 2 and 3 at both ends and is suspended between the supports, and the other The bottom surface of the U-shaped steel pipe 7 with clamps, which has cylindrical clamps n attached to the opposing supports 4 and 5 at both ends and is suspended between the supports, is a small protrusion provided at the center of the upper surface of the horizontal frame a. It is placed and supported on top of e. Above the clamp m is a spring 8 with a clamp, which has a cylindrical clamp p attached to one of the opposing columns 2 and 3 at both ends and is suspended between the columns, and above the clamp n. There is a spring 9 with a clamp, which has cylindrical clamps q attached to the other opposing columns 4 and 5 at both ends, and is suspended between the columns. Please note that the support palette (hereinafter referred to as "palette")
It is called. ), the clamp m of the U-shaped steel pipe 6 with a clamp and the supports 2, 3 are connected to the bottom of the U-shaped steel pipe 6 with a clamp and a small protrusion in the center of the upper surface of the horizontal frame a of the bottom frame 1. Weld e and
In addition, the clamp n of the U-shaped steel pipe 7 with a clamp and the supports 4 and 5 are welded, and the bottom surface of the U-shaped steel pipe 7 with a clamp is welded to the small protrusion e in the center of the upper surface of the horizontal frame a of the bottom frame 1. , 3, 4, and 5 may be welded to the round holes d, which are the connection points of the bottom frame 1, respectively. Also, the lower end portions 2' of the main bodies of columns 2 to 5
Hooks F on which the lifting wires are hooked are attached to ~5' respectively, and the U-shaped steel pipes 6 and 7 with clamps are removed from the clamps m and n, and the springs 8 and 9 with clamps are removed from the clamps p and q. respectively pleated rubber tubes 10, 11, 12, 13
Cover with

(b) Effect The structure of the present invention makes the pallet lightweight and strong.
Storage, organization, handling, movement, and transportation of supports function functionally. In addition, pillars 2 to 5 of this palette
In configuring the springs 8 and 9 with clamps, the supports are stacked one after another on a pallet, and when the height reaches approximately the top of the four pillars 2 to 5, the allowable limit of support loading is determined. If this pallet is constructed in such a way that the clamps p and q of the springs 8 and 9 with clamps are locked to the supports 2 and 3 and 4 and 5, respectively, so that the supports are reliably bound by the elasticity of the springs. In other words, the springs 8 and 9 with clamps are set at a height such that the tops of the clamps p and q of the springs 8 and 9 with clamps are slightly higher than the tops of the supports 2 to 5, and the springs 8 and 9 with clamps are set at such a height that the tops of the clamps p and q of the springs 8 and 9 with clamps are slightly higher than the tops of the supports 2 to 5, so that support bundling within the allowable limit can be achieved. If it is configured so that it can be locked to the supports 2 to 5, when only one pallet is used, the clamp of the spring with clamp is pushed down and tightened to bind all the supports, but when stacking pallets, Even if the lower pallet spring clamp is loosened, the bowl at the bottom of the upper pallet support will push down the lower spring clamp at the upper end of the lower pallet support, so the lower pallet will be supported. are tied together by the elasticity of the spring and do not move.

C. Effects of the invention (a) A bottom frame made of steel pipes as an intermediate support and a framework, and a U with a clamp placed on the small protrusions of the bottom frame.
Since the pedestal is made up of shaped steel pipes, there is a gap in the pedestal (a), so the pallet is light and easy to carry when empty, and the support (b) can be easily stored and organized. This saves labor and allows the claw of the forklift to be inserted after loading the c-support, allowing the support to be taken out from the pallet alone.Also, when taking out the d-support, it is easy to hang the crane wire, and the support can be easily removed. The load shall not collapse when lifted.

(b) The pallet support is supported by a U-shaped steel pipe with a clamp and a spring with a clamp, and a bowl-shaped member is provided at the bottom end of the support, so it is possible to store a heavy support with a complex external structure. This has the advantage that the strength of the supports is maintained and does not deform, and pallets can be stacked safely and reliably.
