Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a hanging frame for suspending a plate-like object in a horizontal state, and in particular, a hanging frame for suspending a plate-like object such as an asphalt pine etc. to a large extent. The present invention relates to a hanging frame that is configured to be supported in a horizontal state without being tilted or bent, and to enable safe cargo handling and laying work at construction sites, etc.

(Prior art) When handling a plate-like object that is wider than the conventional one, a hanging frame of a size that almost matches the width and length of the plate-like object is used, and a substantially horizontal line is placed under the hanging frame. There are cases where it is required to support plate-shaped objects and carry out cargo handling.

However, if the plate-like body is relatively rigid or flexible and there is no effect even if it is bent or deflected, the shape and structure of the hanging frame will change. Although this is not a particular problem, it is conventionally used when the plate-like object is extremely susceptible to bending, or when it is undesirable to carry out cargo handling in a bent state. Depending on the hanging frame used, this may not be sufficient.

For example, when dealing with plate-like materials such as asphalt pine used at civil engineering construction sites, which have a very large area and are heavy, and which are relatively weak against bending, etc., conventional Hanging frames have the disadvantage of not being able to adequately accommodate these characteristics.

The above-mentioned asphalt pine is a relatively large plate with a thickness of 3 to 8 cm, a width of 2 to 7 m, and a length of 5 to 10-odd meters, and its weight is several tons to tens of tons. The main body is made up of asphalt mastic with reinforcing members inserted between them. The asphalt pine can then be laid at the foundation of a breakwater to prevent the foundation from being scoured by waves, or installed at the bottom of a caisson to increase the caisson's sliding resistance due to waves, or used to protect river banks. foundations, protection members for the foundations of underwater structures,
It is also used as a mat member to prevent water leakage.

Asphalt pine with the above structure is manufactured to a specified size at a manufacturing yard on land, lifted by a crane, transported by truck or ship, and installed at the construction site. In such cases, a crane is used to unload the load to the site where the foundation is to be laid, the ground is leveled in advance, the foundation is sunk and laid, and a structure is built directly on top of the foundation. Construction of foundation rubble, etc.

As mentioned above, when handling asphalt pine, it is necessary to use a lifting device such as a crane.
- Using a hanging frame as shown in Publication No. 18454,
In many cases, we handle plate-shaped materials such as asphalt pine.

This hanging frame is as shown in Figs. 10 and 11, and the hanging frame 1' is approximately made up of side beams 2 and 3 arranged vertically and horizontally, and vertical beams 5 etc. that connect the side beams. The asphalt mat 30 is constructed in a lattice shape, and is supported through a support member 33 provided protruding from the lower part of the support member 33.
A wire rope 31 provided at the end of the wire rope 31 is locked and suspended.

However, when hanging the asphalt pine 30, if the asphalt pine 30 is bent in the state shown in the figure, accidents may occur such as cracks or bends when lifting or lowering the asphalt pine 30 to the ground. There were times when the expensive asphalt pine became unusable.

Therefore, in order to prevent the above-mentioned accidents from occurring, it is necessary to use a hanging frame that maintains the asphalt pine horizontally with respect to the hanging frame and prevents it from bending. In many cases, a hanging frame of a size matching the size of the asphalt pine is used. However, since the size of components such as asphalt pine varies depending on the construction site, the hanging frame must be specially manufactured or modified for each site. This cost is also a major cause of rising construction costs.

Furthermore, when a suspension frame is manufactured in a factory and transported to a construction site, there are restrictions on its length and width in order to load it onto a truck and drive it on public roads. Although they are manufactured in a state in which they are assembled and assembled on-site by tightening bolts, etc., the labor and cost of assembly are extremely burdensome.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned drawbacks of the hanging frame conventionally used, and consists of the members constituting the hanging frame as relatively small section members. By assembling the members in a slidable manner, it is possible to set the size of the hanging tool according to the size of the plate-like object, and by reducing the size, transportation is made easier. The purpose of the present invention is to provide a hanging frame that can be easily assembled, and furthermore, to provide a hanging frame that can sufficiently handle the loading and unloading of plate-like materials that are relatively susceptible to bending, such as asphalt pine. The purpose is

(Means and effects for solving the problems) The hanging frame of the plate-shaped body of the present invention is constructed by combining pipes having a square or round cross section, and the upper part thereof has the following features:
In addition to protruding hanging tools that are fixed to the crane's hanging rope, the side beams provided on both sides in the width direction each have a large number of projecting ropes attached to the ends of the asphalt pine. Equipped with hanging hardware.

The hanging frame of the present invention also includes a side beam disposed in the longitudinal direction, a vertical beam disposed in a direction perpendicular to the side beam from the end thereof, and for connecting the side beams on both sides.
It is constituted by a plurality of vertical and horizontal beam members arranged in the middle thereof.

The hanging frame of the present invention is formed by a plurality of section members divided into L-shape, T-shape, cross-shape, etc., and by combining these members, the hanging frame can be configured. It's summery.

In addition, when combining each section member, a fixed connection part and a slidable connection part are used, and in the sliding connection part, one frame member is connected to the other frame member. On the other hand, since the connecting part is formed in such a way that it can slide and be fixed,
If the width and length of the plate-like objects, such as asphalt pine, differ, the width and length of the hanging frame will be changed accordingly, and the lifting work will be carried out in a manner that does not apply excessive force to the plate-like objects. Furthermore, when transporting the hanging frame, it can be reduced to fit the size of the truck bed.

Therefore, the size of the hanging frame of the present invention can be changed to suit different sizes of asphalt pine depending on the construction site, making it possible to use a different hanging frame for each site.
