BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a cable support insert to be mounted on a deck plate, and more particularly to a cable support insert for a floor formwork which can be mounted on a deck plate extremely easily.

[0002]

2. Description of the Related Art Conventionally, an insert is an insert device described in Japanese Utility Model Publication No. 2-17048 previously proposed by the applicant and a cable for a deck plate described in Japanese Patent Application No. 3-32137. There are supporting inserts. In addition, JP-A-60
-141963 discloses a member to be mounted on a plywood slab formwork.
Is shown .

The former device is one in which an insert is inserted into a mounting hole drilled in a deck plate and mounted, and is embedded in a slab. From below the fixed insert,
A suspension iron wire for suspending a cable is used by inserting and fixing it inside the insert.

The latter insert, like the former device, is one in which the insert is inserted and inserted into the mounting hole of the deck plate, and a rod-shaped suspension is projected below the insert, and this suspension is mounted. The cable is inserted into and supported by the insertion port formed on the side surface of the cable. Furthermore, plywood slab formwork
For the components to be attached to the
A disk-shaped member is embedded in the bottom surface of the
The reet supports the member .

[0005]

However, in the former device, it is necessary to insert and fix the suspension iron wire for suspending the cable for each insert, and thus the cable suspending work is troublesome.

On the other hand, the latter insert is inconvenient for suspending a cable which does not follow the opening direction because the opening direction of the insertion opening opened on the side surface of the suspension body is restricted to a fixed direction. is there. Moreover, when the cable is inserted into the insertion port and the wiring is completed, it is difficult to change the wiring direction of the cable thereafter.

Also, a member to be mounted on the slab formwork of plywood
This concrete supports the member,
Since the member is disk-shaped, the embedded part is small.
Therefore, there is a problem in the supporting strength of the member .

Therefore, the present invention has been devised to solve the above-mentioned problems, and it is easy to mount the insert and suspend the cable, and also to secure it securely.
An object of the present invention is to provide a cable support insert for floor formwork that can obtain strength and can route cables in any direction.

[0009]

In order to achieve the above-mentioned object, the first means of the present invention is an inserting portion 1 to be inserted into a mounting hole P1 opened in a floor form P, and this inserting portion. 1 and a locking portion 2 that locks at the upper opening edge of the mounting hole P1 are provided, and the cable Q is bound and supported in a through hole 3 that penetrates the insertion portion 1 and the locking portion 2. The flexible linear tightening tool 4 is inserted and fixed, the locking portion 2 projects above the floor form P, and the tightening tool 4 forms a loop above this locking portion 2.
Then locked .

Further, the tightening tool 4 for binding and supporting the cable Q according to the second means of the present invention is equipped with a separator 5 for separating the binding portion into a plurality of portions.

[0011]

According to this invention, the insertion portion 1 is inserted from the upper portion of the mounting hole P1, and the engagement portion 2 provided on the upper portion of the insertion portion 1 engages with the upper surface of the floor form P. Then, the tightening tool 4 inserted into the through hole 3 penetrating the insertion portion 1 and the locking portion 2 binds and locks the cable Q.

Further, the tightening tool 4 is fixed by locking the loop portion formed on the upper portion of the locking portion 2 to the locking portion 2.

The separator 5 separates the binding positions of the cables Q into a plurality of stages.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 is an insertion portion which is inserted from above into a mounting hole P1 formed in the floor form P. Floor form P shown
Shows a floor form P using a deck plate, but the mounting hole P1 may be opened in the floor form P using a control panel. When the floor form P is a deck plate, the mounting hole P1 is drilled using a dedicated punch having a punch punch at the tip of the slide hammer. At this time, the mounting hole P1 is formed in a tapered tubular shape along the shape of the tip of the punching punch, so that the shape of the insertion portion 1 also fits in the tapered tubular shape. (See FIG. 1).

The locking part 2 is provided on the upper part of the insertion part 1 and is locked to the upper edge of the opening of the floor form P. In the locking portion 2 of the illustrated example, a tubular portion 2B is projectingly formed on the upper portion of the locking flange 2A that is locked to the upper edge of the opening of the mounting hole P1, and a feather-shaped reinforcing piece 2C is formed on the peripheral side surface of the tubular portion 2B. It is provided radially to strengthen the locking portion 2 (see FIG. 2).

The through hole 3 penetrates the insertion portion 1 and the locking portion 2 in the vertical direction, and the tightening tool 4 is inserted therein. The through hole 3 shown in the drawing has a stub shape having a narrowed longitudinal center portion, and the tightening tool 4 is forcibly clamped at the narrowed central portion (see FIG. 3). By doing so, rattling of the tightening tool 4 inserted into the through hole 3 is prevented, and since the opening portion of the through hole 3 is wide, the work of inserting the tightening tool 4 is facilitated. Further, when the insertion portion 1 and the locking portion 2 are integrally molded of plastic, the through hole 3 can be easily molded.

The tightening tool 4 has a flexible linear shape.
We plan to use a bind wire whose wire is covered with vinyl resin. At this time, the tightening tool 4 is inserted into the opening end portion bent in two toward the lower side of the through hole 3, and the bent portion of the upper part of the through hole 3 is formed into a loop shape, so that the tightening tool 4 is locked. 2 is locked (see FIG. 2). Then, twisting is applied to the downwardly projecting portion of the through hole 3, and the twisted portion is unwound to bind the cables Q, so that the unwound length of the twisted portions allows the cable Q to be bound. It can be set (see FIG. 4). Further, FIG. 5 shows a state in which the two tightening tools 4 are inserted into the through hole 3 in a twisted state.

FIG. 6 shows a separator 5 attached to the tightening tool 4. This separator 5 is used when bundling the cables Q by dividing them into a plurality of stages.
Planes such as a flat S shape like A, a flat 3 shape like a 3 type 5B, and a shape that binds together two tightening tools 4 into one like a overlapping type 5C are planned. ing.

[0020]

The present invention achieves the original purpose by being configured as described above. That is, according to the first aspect of the present invention, the fastener 4 for binding the cable Q by simply inserting the device insert from above the floor form P into the mounting hole P1.
Since it is possible to mount the above, it is possible to save the labor of inserting the suspension iron wire into each insert as in the conventional insert device. Moreover, since the tightening tool 4 has a flexible linear shape,
The cable Q can be routed in any direction.

Further, since the locking portion 2 projects above the floor form P, the confirmation becomes easy even if it is mounted in the recess of the deck plate. Further, since the tightening tool 4 is locked above the locking portion 2 in a loop shape, the tightening tool 4 inserted into the through hole 3 can be easily fixed, and the loop portion should not be stepped. Even if it is turned sideways due to being caught, since this loop portion is buried inside the inner part of the slab, there is an advantage that a reliable fixing force can be obtained.

According to the second aspect, since the cables Q can be bound in a plurality of stages, wiring in multiple directions is possible at one time.

As described above, according to the present invention, the mounting work of the insert and the suspending work of the cable are easy, and moreover, the cable can be routed in any direction, and a reliable fixing force can be obtained. It has various beneficial effects.
