Description

[Detailed description of the invention] This invention is based on the unbonded PC steel wire placed on the slab formwork.
Alternatively, the present invention relates to a support fitting that is placed on a beam formwork and supports the beam formwork appropriately.

Unbond placed continuously in concrete
The PC steel wire must be placed with high precision in a substantially suspended curve.

Conventionally, unbonded PC steel wires have been installed by hanging them from the upper reinforcement on the slab, or by placing them on arbitrary spacers placed on the slab formwork each time. However, there was no suitable method or metal fittings for either method, which significantly reduced the accuracy of construction.

Particularly when bar-shaped spacers are used, it takes time and effort to bundle and wire multiple unbonded PC steel wires, and it is difficult to secure an appropriate height.

The purpose of this invention is to eliminate the disadvantages of the above conventional example,
To provide a support fitting for unbonded PC steel wire for construction, which can bundle and accurately support a plurality of unbonded PC steel wires, is easy to handle, and has excellent workability.

However, according to the present invention, the purpose of the lever is to drill a through hole for fixing a nail in the horizontal end of the substantially V-shaped support leg that will touch the ground, and to attach a nut to the top horizontal part of the support leg. A column using a bolt is screwed to this nut so that its lower end protrudes through the center of the support leg, a positioning nut is screwed in the middle of the column, and a plurality of unbonded PC steel wires are attached to the upper end. A horizontally elongated U-shaped catch seat with a width large enough to fit books side by side is provided, a through hole is formed in the upper part of the left and right rising walls of the catch seat, a bent locking part is formed at one end between the through holes, and a locking part is formed at the other end. This is achieved by removably mounting a locking pin with a snap pin insertion hole drilled in the top.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a partially cutaway front view showing an embodiment of the support fitting of the present invention, FIG. 2 is a partial side view of the same, and FIG. 3 is a perspective view of the same.

In the figure, 1 is a roughly V-shaped supporting leg that widens at the end, and is made of metal plate material, and has a horizontal lower end 1a that becomes the grounding part.
A through hole 2 for nailing was bored in the hole.

A nut 3 is attached to the top horizontal part 1b of the support leg 1 by passing through it, a support column 4 using a bolt is screwed to the nut 3, and the lower end thereof is made to penetrate and protrude so as to be located at the center of the support leg 1.

The center of the lower surface of an oblong U-shaped seat 5 is fixed to the upper end of the support 4, and a through hole 6 is formed in the upper part of the rising wall 5a at the right and left ends of the seat 5.

The locking pin 7 has a bent locking portion 7a formed at one end and a through hole 9 for inserting the snap pin 8 at the other end.
is passed from the through hole 6 of one rising wall 5a of the seat 5 to the through hole 6 of the other rising wall 5a, and the locking pin 7 is mounted in the opening 5b of the seat 5.

Note that the inner dimensions of the catch seat 5 are, for example, unbonded.
The length should be enough for three PC steel wires 10 to be inserted side by side.
Also, the distance from the bottom of the catch seat 5 to the lower end of the through hole 6, that is, the lower end of the locking pin 7 to be mounted, is the unbonded distance.
The diameter is approximately equal to the diameter of the PC steel wire 10.

A plate nut 9 may be screwed onto the support 4 for positioning.

Next, I will explain how to use it.
The receiving seat 5 is attached to the frame, dimensions are determined for positioning on a formwork such as a slab, and the supporting metal fitting of the present invention is placed. At that time, the support leg 1 is nailed through the through hole 2.

On the other hand, the length of the catch 5 is adjusted by moving the catch 5 up and down with respect to the support leg 1 by appropriately rotating the support 4 screwed into the nut 3.

The locking pin 7 is not mounted on the catch seat 5 yet, so three unbonded PC steel wires 10 are inserted in a row from the opening 5b of the catch seat 5, and the through hole 6 of one rising edge 5a of the catch seat 5 is inserted. From there, insert the end of the locking pink 7. In this way, the locking pin 7 is passed through between the through holes 6, 6, and the snap pin 8 is attached to the through hole 9 at the end. There is no escape from the
In addition, a plurality of unbonded PC steel wires 10 are connected to the locking pin 7
It is fixed in the catch seat 5 via.

In addition, the length adjustment of the catch seat 5 may be performed after fixing the unbonded PC steel wire 10 to the catch seat 5, and finally the support leg 1 may be nailed.

As mentioned above, the unbond for construction of this invention
For the support fittings for the PC steel wire, a horizontally elongated U-shaped catch is provided on the support leg that widens at the end so that it can move up and down, and a locking pin is removably installed in the opening of the catch, so the unbonded PC steel The wire can be supported at an appropriate height, efficiently securing a substantially suspended curve, and multiple PC steel wires can be bundled easily and easily by simply attaching and detaching a single locking pin. Moreover, it can be done quickly and has good workability.
