Description
The present invention relates to a through-sleeve fixing pin for fixing a through-sleeve, etc. installed in the upper formwork during the building construction process, in particular, simply fixing the through-sleeve, etc. in the upper formwork made of aluminum that is light, durable and semi-permanent use It is made of hardened plastics to easily remove the formwork after concrete pouring, and has a cylindrical body with a groove having a constant width from the bottom to a certain height, and formed at both ends of the groove and having a larger diameter than the body. It consists of a head having a diameter larger than the diameter of the fastening means insertion groove of the through sleeve formed in the upper portion of the body and the narrowing jaw formed narrower toward the lower end to easily fix the through sleeve to the formwork by hitting the head with a hammer or the like. It provides a through sleeve fixing pin that can be.
In general, in order to construct a wall or floor in a building process such as an apartment, a frame is formed by formwork, and concrete is poured into or between the formwork to form a floor and a wall by removing the formwork. At this time, before curing the concrete, various kinds of through sleeves were fixed to the formwork and concrete was poured.
Figure 1 shows an embodiment of the
As a method of fixing the through sleeve to the formwork as described above, in the case where the formwork is wood such as plywood, the nail is inserted into the fixing means insertion part and lowered with a hammer or the like to fix the through sleeve to the formwork.
However, at present, many construction sites are using semi-permanent formwork made of aluminum alloy in order to be used semi-permanently, to improve the work convenience of the worker, and to reduce the labor cost of carpenters generated when assembling the formwork. When using the aluminum formwork as described above it was not possible to use a fixing means such as nails or screws as in the conventional wooden formwork.
Accordingly, as a method for fixing the through sleeve to the aluminum formwork as described above, a hole is formed at the center of the position where the through sleeve of the aluminum formwork is installed, and a through sleeve having a temporary cover is positioned on the hole. Next, a hole is formed in the center of the temporary cover, and the transfer bolt passes through the formwork upper surface from the bottom of the hole formed in the formwork. Next, the transfer bolt is passed through a hole formed in the temporary cover of the through sleeve, a metal rod having a length larger than the diameter of the through sleeve is inserted into the passed portion, and then a nut is formed on the metal rod to form an aluminum die. The through sleeve was fixed to.
However, as described above, the method of fixing the through sleeve by using the transfer bolt is difficult to accurately position the through sleeve at the designed position, and there is a problem that the through sleeve may be shaken or displaced from the correct position by using one fixing means. .
In addition, there is a problem that the through sleeve may be deformed or damaged during the fastening of the nut because the nut must be tightened in order to prevent the inflow of the bottom of the through sleeve.
In addition, it is complicated and cumbersome to insert the horizontal bar into the transfer bolt and tighten the horizontal bar with bolts. There was also a problem because it takes a lot of time.
In order to solve the above problems, the present invention provides a through sleeve fixing pin which can be inserted into a fixing means insert formed at the bottom of the through sleeve currently used to fix the through sleeve to the aluminum formwork with a simple hammering. Its purpose is to make it easy to dismantle the formwork without additional work when dismantling.
In addition, fixing in the molded state without the need to form a hole in the temporary cover of the through sleeve
Since the means insert part is used as it is, no additional fixing is required, and a plurality of fixing parts are fixed to the formwork, so that a gap occurs at the bottom of the formwork and the through sleeve, thereby preventing the inflow of concrete at the source.
In order to achieve the above object, the present invention, the cylindrical body having a diameter equal to or less than the inner diameter of the fixing means insertion portion of the form fixing part formed on the lower end of the through sleeve, the hook formed by vertically cutting the middle portion of the body A jaw flow groove, and formed on both sides of the flow groove, the upper end is larger than the diameter of the fixing means insertion portion and toward the lower end of the tapering shape of the tapered shape the same as the diameter of the body, the end integrally formed on the lower end of the body It provides a through sleeve fixing pin, characterized in that consisting of a guide portion having a narrower shape toward the top, and formed on the body and having a head having a diameter larger than the inner diameter of the fixing means insertion portion.
The through sleeve fixing pin provided according to the present invention is inserted into the fixing means insert formed at the bottom of the currently used through sleeve to provide a through sleeve fixing means for fixing the through sleeve to the aluminum formwork with a simple hammering installation of the through sleeve. The work is simple and can be dismantled easily without disassembly.
In addition, fixing in the molded state without the need to form a hole in the temporary cover of the through sleeve
Since the means insert portion is used as it is, no additional fixing is required, and by fixing a plurality of fixing parts to the formwork, a gap may be generated at the bottom of the formwork and the through sleeve, thereby preventing the concrete from being introduced.
Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
First, Figures 2 and 3 show an embodiment of a through sleeve fixing pin for fixing the through sleeve to the aluminum formwork according to the present invention, the same as the inner diameter of the fixing means insertion portion of the formwork fixing portion formed on the bottom of the through sleeve A
In addition, the

4 is a partial cross-sectional view of fixing the through sleeve to the aluminum formwork using the through sleeve fixing pin according to the present invention. In order to use the through sleeve fixing pin, the through sleeve is positioned at the designed position of the
In general, when the aluminum formwork is re-installed on the upper layer, since the formwork on its place is installed at the position of the upper layer, the hole formed to fix the through sleeve to the formwork can be used as it is. There is no need for additional drilling.
Next, Figure 5 shows another embodiment of the through sleeve fixing pin according to the present invention, the
Next, Figure 6 shows another embodiment of the through sleeve fixing pin according to the present invention, a cylindrical body having a diameter equal to or less than the inner diameter of the fixing means insertion portion of the form fixing portion formed on the bottom of the through sleeve ( 31), the locking
The through sleeve fixing pins of FIGS. 5 and 6 pass through holes formed in the fixing means inserting portion and the formwork formed in the through sleeve fixing portion to fix the through sleeve to the formwork as described in FIG. 4.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be appreciated that one embodiment is possible. Accordingly, the true scope of the present invention should be determined by the technical idea of the claims.
