Description

[Detailed Description of the Invention] <Industrial field of application> The present invention relates to a metal foam sizing tool used for concrete construction at a construction site. Specifically, it is easy to stack a large number of metal foams. The present invention relates to a bundling tool that can be bundled securely and reliably.

<Prior Art> In general, a large number of metal foams are used during concrete construction at a construction site, but when not in use, they are often stored in a warehouse. At the time of use, they are unloaded and transported, piled up on site and awaiting use. After the construction is completed, these metal foams are carried onboard to the washing area for cleaning, and then they are mounted on the vehicle again and stored in a highly loaded state. This series of work is repeated every time the site changes.

<Problems to be solved by the invention> By the way, since many of these metal foams are conventionally stored simply in a stacked state, the above-mentioned series of unloading and carrying work is troublesome, especially in a warehouse. There is a problem in that it is troublesome because it requires special consideration so that the upper part does not collapse during stacking or transportation on the vehicle, and it tends to be messy at the site and makes the environment dirty.

Therefore, the present invention proposes a large number of metal foam groups, for example 40
We provide a focusing tool that can easily and securely bind and unbundle 50 metal foams in a stacked state.
Therefore, the object is to solve the above problems.

<Means for Solving the Problems> In order to achieve the above object, the present invention comprises a pair of left and right vertical columns made of angle members and horizontal abutting plates attached to the upper and lower end portions of these columns. At least one of the contact plates is connected to the column via a connecting means that is adjustable in vertical movement, and a retaining projection is provided on the upper surface of the lower contact plate to project upward. Is.

In order to bind the metal foams more reliably, it is preferable that protrusions are provided on the lower surface of the upper contact plate and the upper surface of the lower contact plate to prevent them from coming off.

Further, a hook for hanging may be formed on the side surface of the column.

<Operation> The above-mentioned focusing device is a set of two, and is attached to both side surfaces of the metal foam group A .. That is, the angle-shaped left and right columns are closely contacted so as to cover the corners of the stacked metal foam group, the upper and lower contact plates sandwich the upper and lower sides of the metal foam group, and a vertically movable adjustable connecting means is used. Tighten the upper and lower contact plates against the metal foam group to fix them. As a result, a large number of metal foam groups are bundled into a cube.
In this case, if protrusions are provided on the lower surface of the upper contact plate and the upper surface of the lower contact plate to prevent them from coming off, it is ensured that these protrusions come into contact with the inner surface of the frame plate of the metal foam A and the bundling tool comes off. To be prevented.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

1 to 7, horizontal metal contact plates 2 and 2 are attached to the upper and lower end portions of a pair of right and left vertical columns 1 and 1 made of a metal angle material. The lower plate 2 is a pillar
The upper contact plate 2 is fixed to the columns 1,1 by means of welding or the like, and the upper contact plate 2 is connected to the columns 1,1 by vertically movable connecting means. In the embodiment, the connecting means causes the vertical bolt 4 fixed to the contact plate 2 to pass through the bolt receiving hole 5 of the horizontal receiving plate 10 formed in series with the support column 1 and the nut 6 at the through end. It is configured by screwing.

Instead of the upper contact plate 2, the lower contact plate 2 may be movably connected to the support column 1 through the same connecting means as described above. Further, as the connecting means, a shrimp metal fitting which is generally used as a tightening metal fitting may be used. In this case, the tightening between the upper and lower metal fittings (2) and (2) can be performed with one touch. It can be done quickly and conveniently.

Thus, projections 3 are provided on the lower surface of the upper contact plate 2 and the upper surface of the lower contact plate 2 to prevent them from coming off, and when the metal foam is focused, it abuts against the inner surface of the frame plate A ₁ of the metal foam A for focusing. Prevents the tool from coming off the metal foam.

Further, in the embodiment, an auxiliary strut 11 is provided at an intermediate portion between the left and right struts 1,1. The auxiliary column 11 reinforces the focusing tool and, as shown in FIG. 4, prevents the central row of metal foam from coming off when the three rows of metal foam groups are focused.

Further, a hook 7 for hanging which is convenient for hoisting by a crane or the like is provided on the side surface of the columns 1, 1. The hook 7 may be formed in a C shape as shown in FIG.

Furthermore, a groove portion 8 is formed on the lower surface of the lower strut 2 and
On the upper surface of each, there are provided protrusions 9 each of which fits into the groove portion 8. This prevents lateral displacement when the metal foam groups A ... Focused by the concentrator of the present invention are stacked above. It can be prevented. In this case, as shown in FIG. 7, if the projection 9 is provided with a step 9a so that the edge of the groove 8 abuts against it, the deviation in the step direction can be prevented at the same time.

<Effects of the Invention> Since the present invention is configured as described above, a large number of metal foam groups can be easily and surely bundled into a cubic shape, so that they can be stacked in an organized and safe manner in a warehouse or on-site. It can be stored and gives a beautiful appearance, saves storage space, and can be stored in a three-dimensionally organized manner so that the inventory number can be determined at a glance, and in addition, unloading and transportation work is easy. It also has an excellent effect that it can be performed safely.

Since there is a protrusion on the upper surface of the lower contact plate to prevent it from coming off,
There is an effect that it is possible to more reliably prevent the metal foam A from coming off from the concentrator due to the protrusion contacting the inner surface of the frame plate of the metal foam A.
