Description

Processing tool for adjusting slab hole size}

The present invention relates to a treatment device for slab hole size adjustment, and more particularly, to a treatment device to be constructed by adjusting the hole size of the slab to a desired diameter using a simple treatment device.

Conventionally, when a hole is formed in a slab and the final hole size is determined and installed, when concrete is to be poured, conventionally, a separate formwork for grouting or concrete casting of the slab hole is used. The work was carried out with a support column at the bottom of the slab.

Therefore, there is the hassle of rebuilding the formwork for concrete placement of small holes, and when the height of the slab is high, reinforcement work must be accompanied with high supporting columns to fill the small holes. There were problems such as high cost.

Accordingly, the present invention is to provide a treatment device for slab hole size adjustment to provide a simple processing device to solve the problems as described above, so that the slab hole can be easily processed even without a formwork as in the prior art.

The support means 30 is a hollow support tube while forming a cylindrical shape so as to have a predetermined length and easy to stand vertically. However, solid shapes or square shapes can be used as much. In addition, a thread is formed on the outer surface.

2 is a cross-sectional view of the clamping means 40. As shown in the drawing, the clamping means 40 includes upper and lower nut members 41 and 42 fitted to the supporting means 30, and the nut member 41. As shown in FIG. A plurality of handle members 44 for easily rotating the nut member 41 on the circumferential surface of the upper nut member 41. The structure is equipped.

The nut members (41, 42) is the support pipe 30 is a support tube 30 is formed in the outer surface is spirally fastened by screwing, therefore, it is possible to move up and down by the spiral of the support means (30) will be.

In addition, the rotation means 50 is coupled to the support means 30, as shown in Figure 3, the hub member 51 which serves as a central axis, and rotates along the circumferential surface of the hub member 51 It is a structure consisting of a rolling member 52 is coupled to a plurality possible.

In addition, the rolling member 52 is composed of a wheel member 53 provided at both ends and a connecting member 54 for connecting the wheel member 53, as shown in Figure 4, the connecting member In 54, a separate rotatable connecting pipe 55 is provided, and a support 56 is fixed to the connecting pipe 55.

The connecting member 54 is formed with a space portion 54a for allowing the connecting pipe 55 to be rotatable.

Between the support 56, the plate 57 to block the hole 11 of the slab 10 is fixed, respectively. These plates 57 are made of steel and welded one by one to the spaces between the supports 56 to fix the eight pieces of plate 57 in the drawing.

On the other hand, the bottom of the support 56 is provided with a separate spacing holding piece 56a, and a separate reinforcing plate 31 is fixed outward from the support means 30 above the center thereof. In addition, a separate nut 32 is screwed to the lower portion of the support means 30 so that the support means 30 is detachable.

In addition, the pulling means 70 to allow the processing apparatus according to the present invention to be expanded and contracted is connected to the support 56 of the rolling member 52 of the rotating means 50 from the clamping means 40.

As shown in FIG. 1 or FIG. 6, the pulling means 70 is made of steel, has a thin thickness, is first formed in a circular shape, and the circular part 71 is a nut member which is the clamping means 40. 41 is fitted to the outer surface of the connecting member 43 between the nut member 42, a plurality of wires 72 connected along the circumference of the circular portion (71). The lower end of the wire 72 is coupled to the support 56, the hook 73 is formed is connected to the ring 56b formed on the support 56, it is fixed.

In the present invention, since eight supports 56 are provided for convenience, the wires 72 are connected correspondingly.

In addition, as shown in Figure 1, the hook means 60 is fitted to the support means 30, the body portion 61 and a plurality of extending support formed at regular intervals in the circumferential direction of the body portion 61 It consists of a hook part 62 of the form.

In the drawings, reference numeral 80 denotes a space holder made of wood, 90 grout, and 100 sleeve.

The present invention configured as described above is inserted into the hole 11 of the slab 10 together with the sleeve 100 of the desired size and filled with the grout 90 between the gap between the hole 11 and the sleeve 100 and cured. After that, it may be separated from the sleeve 100 again.

That is, the hole 11 is blocked when the sleeve 57 is unfolded when the sleeve 100 is inserted to adjust the size of the hole and the plate 57 is unfolded after the insertion is completed.

During the unfolding operation is to be unfolded by its own weight, the support 56 is rotated in the rolling member 52 provided in all directions from the hub member 51 of the rotating means 50 provided in the lower portion of the support means 30 It is possible that the plate 57 is unfolded as the support 56 is rotated. The support 56 is rotatable within the range of the space 54a of the connecting member 54 while being coupled with a separate connecting tube 55 provided in the connecting member 54. At this time, the rotation operation of the support 56 is possible by the pulling means 70, during the unfolding operation, the rotation angle of the support 55 is to rotate only within 60 degrees from the horizontal plane.

After unfolding in this way, the hook portion 62 of the hook means 60 provided on the upper end of the support means 30 may be hanged between the predetermined interval holding zone (90).

When dismantling again after completion of construction, the hook means 60 is separated from the support means 30, and the support means 30 is further lowered downward. At this time, the support means 30 has a sufficient length so that the support 56 and the plate 57 blocking the holes of the sleeve 100 can be folded. Subsequently, when the nut members 41 and 42 of the clamping means 40 are moved in a threaded direction in the upper direction of the supporting means 30, the wire 72 of the pulling means 70 is pulled out and is in an unfolded state. It is sufficient to retract the 57 from the sleeve 100.

The extent to which the support 56 and plate 57 are retracted is not completely folded, but may be folded within a range of approximately 60 degrees, and after folding, may be pulled out through the hole of the sleeve 100 upwards, or The hook means 60 and the clamping means 40 may be separated and then dropped down.

In addition, the nut 32 serves to connect and connect it in a state in which the support tube 30 is divided, so that when the nut 32 is to be stored without use, the nut 32 is released after disassembling and storing. This is to facilitate storage because the support means 30 has a certain length.

Thus, according to the present invention, it is possible to adjust the construction of the slab hole size through a simple treatment device, reducing the work time, and can be directly applied to other hole sizes, thereby saving construction costs. It is.
