[Industrial applications]

 The present invention relates to a load collapse preventing fastening jig capable of isolating a plurality of suspended loads for a predetermined period and binding them in a tight state.

[0002]

[Prior art]

 At the recent building construction sites, in order to rationalize the carrying-in work, for example, beam members etc. are collectively lifted and carried in every 3 to 4 pieces. In general hoisting work, the hoisting load is surrounded by a pair of hoisting wires, and each hoisting wire is slung on the hook of the crane wire to hoist it. Therefore, when hoisting 3 to 4 pieces together, the load during the hoisting is unstable. Yes, there is a risk of falling apart and falling. Therefore, in the past, the lifting work was performed after connecting the pieces with bolts and nuts.

By the way, in recent years, particularly in construction sites, automated machines such as auto-clamps and auto-crows have been introduced to streamline the work. In order to effectively utilize these automated machines, the load between each suspended load is increased. It is necessary to carry them into the site with the intervals kept constant. In other words, if the suspended loads are transported to the loading position while they are in close contact with each other, the machine cannot clamp them, and if they are separated and then clamped, the operating efficiency will be low.

Therefore, based on these requirements, conventionally, both ends of this jig are bolted and tightened with a spacer jig or the like while keeping the suspended load at a constant interval.

[0005]

[Problems to be solved by the device]

 However, with the above method, although there is certainty to prevent a fall accident, the work of unpacking after being brought to the site is laborious and requires labor because the work of unfastening the bolts and nuts is done. Since this is the idle time of the machine, it was not always possible to rationalize or speed up the work.

This invention solves the above problems, and its purpose is to secure a plurality of suspended loads by binding them while isolating them from each other for a certain period of time. Is provided.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is a jig for fastening a suspended load arranged in a plurality of rows on a pallet, wherein the jig is orthogonally disposed on an upper portion of each suspended load, In addition, a top end retainer provided with a belt passing guide on the upper part, a spacer projecting integrally under the top end retainer and entering between the suspended loads, and both ends suspended from both sides of the pallet, the belt A belt that is inserted through the through guide and surrounds the outer circumference of the suspended load, and a fastener that is arranged in a part of the belt and that adjusts the belt so that the belt can be compressed and loosened are provided.

[0008]

[Action]

 According to the above configuration, the spacer is inserted between the suspended loads by disposing the top end presser on the upper portion of the suspended loads arranged in a row. If both ends of the belt are connected to the pallet in this state, the suspended load is surrounded by the belt. Then, if the belt is tightened by using a fastener, the suspended loads are moved closer to each other by the belt lashing and are fixed by the spacer at a constant interval.

When the pallet is installed at the carry-in position and the belt is loosened by operating the fastener, the belt is removed from the pallet and the unloading is completed.

The seat belt 6c is arranged, and a rubber plate 7 for cushion is arranged on the upper surface of the horizontal frame 6b, and the base ends of the suspension belts 4 are locked to both ends of the horizontal frame 6b.

Further, a pair of locking brackets 8 for the fastening jig 2 are provided in a protruding manner on both sides of the vertical frame 6a.

The suspension belts 4 are all formed to have the same length, and a suspension ring 4a that is detachably connected to a suspension jig 5 is attached to the free end side. The hanging jig 5 is made by welding hanging wire locking portions 9 to both ends of H-shaped steel having a length equal to the length between the horizontal frames 6b. The hanging ring 4a is locked on both sides of the locking portion 9. A pair of hooks 10 are integrally provided, and both ends of a suspension wire 12 suspended from a crane hook 11 are annularly connected to the locking portion 9.

A pair of the fastening jigs 2 are provided, and in this case, the top end retainer 15 and the top end retainer 15 which are arranged orthogonal to the upper surface of the suspended load stacked in a row on the pallet 3. It is composed of a fastening belt 16 which is wound around and has both ends releasably attached to the locking bracket 8 and a fastener 17 arranged on a part of the fastening belt 16.

As shown in the enlarged view of FIG. 2, the top end holding member 15 has a bracket 19 welded to both ends of a U-shaped steel material 18 and also serves as a belt, and a belt guide roller 20 is attached to the tip of the bracket 19. It is rotatably held, and the belt loops 21 are arranged at two central positions. The spacers 22 are integrally provided on the lower portions of the steel materials 18 at the lower portions of the respective belt loops 21.

The spacing between the spacers 22 is equal to the width of each beam member 14 when the suspended load is the beam member 14 made of three H-shaped steels, and the width of each spacer 22 is between the beam members 14. It is set to a desirable interval, that is, an interval where it can be immediately chucked by an automatic machine such as a clamp device when it is transported to the loading position.

The fastening belt 16 is wound around the top of the top end presser 15 through the bracket 19 and the belt loop 21, and is fastened to the short fixing belt 16 a connected through the fastener 17. The adjustment belt 16b having a long length is provided, and each end of the adjustment belt 16b is provided with a connecting member 23 that can be engaged with and disengaged from the locking bracket 8 as shown in FIG.

As the fastener 17, for example, the structure shown in Japanese Patent Publication No. 3-75765 is adopted. Although the details of this are omitted, the end portion of the fixed belt 16a is connected to one end side of the buckle 17a, and the end portion of the elastic belt 16b is connected to the winding shaft 17b pivotally supported at the other end of the buckle 17a. It is a connection.
