Description

Apparatus and method for manufacturing through-sleeve for wall retaining wall having a multi-threaded thread in which a stopper and a cylindrical part are integrally formed.

The present invention relates to an apparatus and a method for manufacturing a wall retaining wall through-sleeve having a multi-threaded thread in which a hooking jaw or a hooked thread is formed on an inner circumferential surface of a cylindrical sleeve, and a cap and a cylinder are integrally formed. The present invention relates to an apparatus and a method for manufacturing a through sleeve which can be easily and quickly adjusted by a multi-threaded coupling method or a locking step and a slide method so that the cylindrical portion and the stopper are integrally formed.

The walls of the building must have through-holes through which ventilation, air-conditioning, sprinklers, electrical wiring, sewage, air conditioning ducts, firefighters, gas pipes, and air conditioners pass.

In general, in order to make a through-hole in a building, after fixing a through-sleeve having a certain diameter and width inside the formwork, the concrete is poured to make a through-hole.

The through-sleeve is fixed to the upper end of the through-fitting sleeves as shown in Fig. 1a and fitted with a "b" -shaped coupling piece on the upper end of the fixture, and fixed the bent end of the coupling piece above the formwork, the fastener is also Secure to the formwork.

However, the conventional through-sleeve is fixed to the building formwork through a coupling piece of a constant length, not only is not free to adjust the height, and to install the through-sleeve in the building formwork, after fixing the upper end of the coupling piece to the building formwork, Since the process of fixing the lower end of the coupling piece to the through sleeve is cumbersome, there is a problem that the efficiency of the work is lowered.

In addition, when the width of the building formwork is not constant, it is impossible to adjust the length of the width of the through-sleeve according to the conditions of the site to be installed, there was a problem that can not produce a standardized through-sleeve.

On the other hand, in the case of mounting the through-sleeve in the formwork as shown in Figure 1b in order to increase the strength of the concrete wall inside the formwork between the bars are formed in the form of female, male of a certain size between the tightly formed bars at regular intervals. It was difficult to install the sleeve by inserting the sleeve and adjust the length by the exact height and the width of the formwork, and even though it was inserted between the rebars, the length of the formwork should be as long as the width of the formwork. When adjusting, it is possible to adjust only by rotating the entire through sleeve body that is not fixed. This installation is difficult to install nails or fixtures for fixing in a state where the installation height of the through-sleeve is arbitrarily set inside the formwork where the space is narrow, and the rotation of the through-sleeve with female and male screws requires considerable force. In addition, this rotation and height adjustment in the narrow space was more difficult. In addition, when the sleeve is replaced due to a defective product, it is difficult to maintain due to the fact that it is separated only by rotation.

Patent No. 10-1709634 filed by the present applicant in order to solve the problems described above is a multi-line thread that can be easily and quickly adjusted to the formwork by adjusting the length of the width of the through-sleeve screw thread as shown in FIG. Although the description of the through-sleeve has been described, as shown in FIG. 2B, one side is opened to separate the core forming the inside of the first cylinder by injection molding the through-sleeve in which the thread is formed inside the first cylinder. It was made in the shape, and prepared by crime prevention to separate the core through the open one side. As a result, the plug portion and the first cylindrical portion cannot be formed integrally, and thus, the cylindrical portion and the stopper must be manufactured separately, so that each mold is required and the manufacturing process and the assembly process increase, thereby increasing the production cost.
