Description

Separator for concrete mold

The present invention is an improvement of the separator (form insulating material) that is installed to maintain the mold at a certain interval during concrete construction,

More specifically, it improves the structure of the brace so that the concrete juice can be injected into the brace installed in the male screw portion of the separator and the female screw coupling portion of the tightening bolt, thereby improving the appearance after the concrete construction and preventing the end of the brace from being excessively exposed. It was made possible.

Since the brace applied to the conventional separator is rounded to form a rounded frame as the end is enlarged in the shape of a trumpet, it has a structure that completely covers the outer circumference of the male threaded portion of the separator. If the mold is removed after curing, the inside of the brace is completely exposed to the outside, and when it comes into contact with moisture, it is oxidized to produce rust, which not only contaminates the concrete exterior wall but also causes the appearance to be ugly.

Therefore, it is a cumbersome defect to force the separation of the brace or to fill it in place by putting mortar separately.

The present invention was developed in order to correct the above drawbacks as described above in detail with reference to the accompanying drawings as follows.

Equipped with a fixing portion 101 formed with a chain coupling hole (2) and a cutting portion (3) on one side and a male screw portion (102) formed on the opposite side is screwed with the female screw portion (501) of the tightening bolt (5) washer ( (8) In the mold separator (1) fastened to the mold (6) (7) with the nut (9), the outer part is an enlarged portion (402) inside the male screw portion (102) of the separator (1). 403 is provided, the inner side is made of a configuration that is fixed to the male screw portion 102 inside the brace 4, the reduced connection portion 401.

To this end, the prop 4 of the present invention includes a configuration in which the inwardly bent portion 401a or the annular locking jaw 401b is formed in the connecting portion 401 to be forcedly coupled to the recess groove 103 of the separator. It includes a configuration in which the punching protrusion 401c is coupled to the recessed groove of the external thread by punching the connection portion 401 of the brace 4 to make the recessed groove on the surface and fit the groove. Forming a wrench engaging portion of the protrusions 502 and 503 is included, and is also designed to include a configuration in which two or more cut portions 403 are formed in the enlarged portion of the support 4.

When the present invention is installed between the molds (6) and (7), when the concrete juice solution is poured, the concrete juice solution is introduced into the cutout portion (403) formed in the brace (4), and the female screw portion 102 of the tightening bolt is formed. Sufficient concrete juice is added to the space between the circumference and the brace, so that it solidifies and cures in that state. When the mold is separated, only the male screw part with the tightening bolt is exposed, and the enlarged part of the brace 4 is embedded inside the concrete and is concealed. Construction is neat in appearance.

Therefore, more beautiful concrete can be poured, and the brace 4 is fixed by means of welding or binding to the male threaded portion of the separator 1, so it is installed on the mold to provide sufficient brace action even when the separator is tensioned to function as an insulating material. It is easy to manufacture and the cost can be reduced and the tightening bolt is a connection part formed with a female thread 501 is tapered, and the pliers coupling portion made of quadrilateral or hexagonal protrusions 502 and 503 at the outer end thereof. In this case, when the mold is separated, the fastening bolts 5 are easily disassembled, so that the use can be very convenient, and thus, there is an advantage that the effect of improving the performance of the work can be obtained.
