Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hanging jig used for lifting spancrete laid as a composite floor slab in building construction.

[0002]

[Prior art]

 Conventionally, in laying the span cleats 30, as shown in FIG. 5, a wire is directly hung on the span cleats 30 to be hung by a crane and laid.

[0003]

[Problems to be solved by the device]

 In the conventional laying work of the span cleats 30, it is dangerous to remove the wires, and after the wires are removed, the side surface part 33 of the span cleats 30 is brought into close contact with the side surface part 33 of the span cleats 30 laid before it. It was also necessary to make adjustments.

The present invention has been made in view of the above-mentioned matters, and an object thereof is to make span cleats laying safe and easy.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention forms a suspension jig for suspending span cleats, and the suspension jig has the structure described below.

That is, a hanging plate 15 that hangs downward is provided on the lower surface of the top plate 1, and the side surface of the hanging plate 15 can be inserted horizontally into the hole 32 formed in the end surface 31 of the span cleat 30. A rod-shaped body 22 was provided, and a hanging metal fitting 2 capable of engaging a hanging rope was attached to the upper surface of the top plate 1 to form a steel spancrete hanging jig.

[0007]

As shown in FIG. 4, the spancrete suspension jig of the present invention is such that the rods 22 of the spanclet suspension jig are inserted into the holes 32 at positions near the side surface 33 of the end face 31 of the spancleat 30. Then, the suspension jigs for span cleats are attached to the end faces 31 of the span cleats 30 at four positions.

Then, the rope is engaged with the hanging metal fitting 2 of the hanging jig for spancrete, and the crane is hoisted. Since the span cleat hanging jig is attached to the end surface 31 of the span cleat 30, there is no cord on the side surface portion 33 of the span cleat 30.

Therefore, with the span cleats 30 suspended by the ropes of the crane, the side surface portion 33 of the span cleats 30 can be laid in close contact with the side surface portion 33 of the span cleats 30 laid in front thereof.

【Example】

 Hereinafter, an embodiment of the present invention will be described. 1 and 2 show an embodiment of the present invention.

In this embodiment, an H-section steel having a width of 200 mm and a height of 200 mm is cut into a length of about 200 mm to form a main body. Then, the side portions on both sides of the lower plate 26 of the main body and the other side portion (the side portion on the right side in FIG. 1) of the top plate 1 of the main body are each cut by a width of 50 mm. The width of the other side portion of the top plate 1 is narrower than that of one side portion of the top plate 1 (the side portion on the left side in FIG. 1).

By processing the main body made of H-shaped steel as described above, a hanging plate 15 that hangs downward is provided on the lower surface near the other side of the top plate 1, and at the lower end of the hanging plate 15, What is provided with a lower plate 26 which is parallel to the top plate 1 is formed.

A reinforcing plate 16 is attached to one side surface of the hanging plate 15 formed as described above by welding. The reinforcing plate 16 is attached at a position slightly lower than the central portion of the reinforcing plate 16. A hole 17 is provided.

A base portion of a rod-shaped body 22 formed of a pipe is fitted into the mounting hole 17 and fixed by welding, so that the side surface of the hanging plate 15 is perpendicular to the hanging plate 15 in a horizontal direction. A rod-shaped body 22 that projects to the side is provided.

The rod-shaped body 22 formed of the pipe is formed to have an outer diameter that can be removably inserted into a hole 32 formed in an end surface 31 of a spancrete 30 made of concrete which is laid as a synthetic floorboard. .

Further, on the upper surface of the top plate 1, above the rod-shaped body 22, a suspending metal fitting 2 for engaging a hanging rope is fixed by welding in the same direction as the rod-shaped body 22. ing.

A screw hole 3 is formed on one side of the top plate 1, and a fixing bolt 8 is screwed into the screw hole 3, and a lower end of the fixing bolt 8 is A holding metal fitting 9 that projects horizontally is provided.

Next, a method of using the embodiment will be described. As shown in FIG. 4, the suspension jigs for the span cleats of the above-described embodiment are provided with four rod members of the suspension cleats for spun cleats in the holes 32 at positions near the side surface portions 33 on both sides of the left and right end surfaces 31 of the span cleats 30. 22 are respectively inserted.

Then, the set bolt 8 is screwed in, and the upper surface of the span cleat 30 is pressed by the holding metal fitting 9 provided at the tip of the set bolt 8 to fix the span cleat suspension jig to the span cleat.

Next, as shown in FIG. 4, a rope is engaged with the hanging metal fitting 2 of the hanging jig for the spancrete, and it is lifted by a crane. Since the span cleat hanging jig is attached to the end surface 31 of the span cleat 30, there is no cord on the side surface portion 33 of the span cleat 30.

Therefore, in a state in which the span cleats 30 are suspended by the ropes of the crane, the side surface portion 33 of the span cleats 30 can be laid in close contact with the side surface portion 33 of the span cleats 30 laid in front thereof.

When the span cleat 30 is pressed by the holding metal 9 of the stop bolt 8, when the span cleat 30 is not lifted by a crane, even if another object hits the rope or the span cleat hanging jig, The spancrete hanging jig does not come off from the spancrete 30.

However, even when the stop bolt 8 is not provided, when the hoisting jig for spancrete is pulled by the rope in the direction in which the rod-shaped body 22 is inserted into the hole 32 when hoisting by the crane. , The suspension jig for spancleats cannot be removed.

FIG. 3 shows another embodiment, and the same portions as those in the previous embodiment are designated by the same reference numerals and the description thereof is omitted. In this embodiment, two rod-shaped bodies 22 are provided in parallel on the hanging plate 15 of the spancrete hanging jig.

Further, the pressing fitting 9 provided on the stop bolt 8 may be formed in a disc shape. Further, if the hanging plate 15 is made strong, the lower plate 26 can be removed.

[Effect of device]

 Since the spanclet suspension jig of the present invention is inserted into the hole 32 formed in the end surface 31 of the spancleat 30 and mounted, it is easy to mount, and the spanclet suspension jig mounted on the spancleat 30 at the time of lifting. Is safe because there is no risk of slipping, tilting or falling of the spancrete 30.

Since no rope for lifting is present on the side surface portion 33 of the span cleats 30, the side surface portion 33 of the span cleats 30 is hung in the side surface portion of the span cleats 30 in front of the span cleats 30 in a suspended state. It was possible to hang it in close contact with the 33, and it became unnecessary to move the spancrete 30 after moving it down and adjust it laterally.
