Abstract

PURPOSE: To orderly and high-efficiently load many kinds of or a number of materials on a load-carrying platform by a method wherein frames are vertically stacked in such a way that a recessed groove formed in one of a base frame and a vertical frame arranged at the load-carrying platform of a vehicle is fitted in a protrusion formed on the other. CONSTITUTION: A vertical frame 1 comprises a pair of stays 2 and 2 consisting of a square pipe; rungs 3, 3 to intercouple the stays; and a lower frame 4 consisting of a square pipe to intercouple the lower ends of the stays 2 and 2. Installation foundations 5 and 5 are fixed to the lower ends of the stays 2 and 2. In an installation foundation 5, a protrusion 6 having size enough to fit in the hollow part of the stay 2 is integrally protruded form the lower end of each of the stays 2 and 2. Recessed grooves 7 and 7 are formed in the hollow opening parts of the upper ends of the stays 2 and 2. A base frame 9 forms an integral frame 12 in such way that the lower ends of the stays 2 and 2 of the vertical frame 1 are welded to the respective two ends of horizontal frames 10 and 10. Protrusions 16 and 16 fitted in the recessed grooves 7 and 7 are formed on the under surfaces of the two ends of an upper frame 15.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transportation cradle capable of efficiently transporting residential building materials to the site.

[0002]

2. Description of the Related Art Conventionally, when a large material such as a beam or a roof truss is transported to a construction site by a truck, these materials are piled up as much as possible and loaded on a loading platform for transportation.

[0003]

When the materials are transported in a stacked state as described above, when a large amount of materials are loaded, there is a disadvantage that the members are rubbed against each other and scratched, or the coating or plating is peeled off. For this reason, the amount of material that can be loaded in one truck is naturally limited. Also,
When loading while moving each material storage place in sequence, the worker does not know what to load in the next storage space, so it is not possible to load while considering the arrangement of materials,
Eventually, there is a drawback that the loading becomes inefficient and the transportation efficiency becomes poor.

An object of the present invention is to solve the above-mentioned conventional drawbacks so that various kinds or a large number of materials can be loaded on a bed of a transportation vehicle in an orderly and efficient manner.

[0005]

In order to solve the above-mentioned problems, according to the present invention, a base frame installed on a cargo bed of a transportation vehicle and vertical frames standing upright at opposite ends of the base frame are provided. It is characterized in that a concave groove provided at one upper end of the base frame and the vertical frame and a projection provided at the other end are fitted to each other so that two or more mounts can be vertically stacked.

In the above description, the gantry comprises a plurality of gantry units arranged at intervals in the front-rear direction of the bed of the transport vehicle, and a large material such as a beam or roof truss is laid across the pedestal frames of these gantry. It is possible to install it.

Further, it is conceivable that the upper frame is mounted so as to straddle the upper ends of the vertical frames to reinforce the gantry frame, and further, another material is placed on the upper part.

[0008]

As described above, according to the present invention, it is possible to load materials into each cradle frame in an orderly manner, and by stacking these cradle frames in two or more stages,
It is possible to stack many materials in multiple stages without stacking them on top of each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, (1) is a vertical frame, and a pair of parallel columns (2) and (2) made of square pipes.
And a horizontal bar (3) (3) made of a round bar or a round pipe that connects the columns (2) and (2), and a lower frame of a square pipe that connects the lower ends of the columns (2) and (2) It is composed of (4) and. Installation bases (5) and (5) having a trapezoidal cross section with an open lower surface are fixed to the lower ends of the columns (2) and (2). In addition, as shown in FIG. 2, in this installation base (5), a projection of a size that fits in the hollow portion of the column (2) at the lower end of the column (2).
(6) is integrally projected. In this example, each strut
(2) The hollow opening at the upper end of (2) is formed with the concave groove (7) (7) of the present invention.
It is assumed that.

(9) is a pair of horizontal rectangular horizontal pipes (10) (10) parallel to each other, and a round bar or a round pipe connecting the horizontal frames (10) (10). This is a stand frame of the present invention comprising horizontal crosspieces (11) (11) ... Welded to form an integrated pedestal (12).

The upper frame (15) is a square pipe having the same length as the length between the pair of vertical frames (1) (1), and the concave grooves (7) are formed on the lower surfaces of both ends thereof. Approximately U-shaped projections (16) and (16) that fit into (7) are integrally provided. Further, similarly, projections (17) (17) ... Which are short cuts of the square pipe are provided on the upper surface and the central portion of both ends.

The mount 12 constructed as above is shown in FIG.
And, as shown in Fig. 4, according to the length of the material to be loaded, a plurality of materials (19) are stacked on the loading platform (20) of the transportation vehicle (18) at a front and rear space and stacked in an appropriate amount. In addition, the material (20) that does not require a high side frame such as the vertical frame (1) is placed between the upper frames (15) and (15). In this case, a wide object can be placed by using the upper frame (15) without the two central protrusions (17) (17).

Further, as shown in FIG. 4, projections (6) at the lower ends of the other pedestals (12) are provided at the upper ends of these pedestals (12) and concave grooves (7) (7) (7) (7) at the upper end of the vertical frame (1). Other materials can also be loaded between the upper racks (12) while fitting them from above, and by stacking the materials in multiple stages in this manner, many materials can be placed at the same location. It can be efficiently loaded onto the loading platform as compared to the case of stacking on. In FIG. 4, the upper frame (15) is not used, but it is of course possible to attach the upper frame (12) to the upper end of the vertical frame (1).

FIG. 5 shows another mount on top of the mount (12).
(21) is installed. This second mount (21)
Has a width approximately half that of the first gantry (12), and is provided with an H-shaped pedestal frame (22) and vertical frames (23) at both ends of the pedestal frame (22) as viewed from above, Inside the installation base (24) with a trapezoidal cross section provided at the lower end of the frame (23), the first base (12)
The same projection (25) is provided. Then, the first mount (1
2) First, attach the upper frame (15) as described above, and then open the upper groove (1) of the protrusion (17) of the upper frame (15).
The protrusions (25) of the second pedestal (21) are fitted and installed on the 8) from above. Reference numeral (26) denotes a material placing frame installed on the base frames (22) and (22) of the pair of second mounts (21) and (21) thus installed. The second mount (21) may have the same width as the first mount (12).

[0015]

As described above, according to the present invention, since it is possible to stack the gantry in two or more steps and to load the building materials while partitioning the building materials, it is possible to compare a large number of materials on the same plane. The materials are less likely to be rubbed against each other and damaged, and more materials can be loaded than in the conventional case, and the transportation efficiency can be significantly improved. Further, since there is less risk of being damaged in this way, it is possible to omit packaging or packing with corrugated cardboard or plastic, and there is an effect that the disposal processing of these is unnecessary.
