To achieve the above object, according to the present invention, there is provided a vertical bar comprising: a rectangular hollow vertical bar having a through hole formed at a predetermined position in an upper and a lower portion, a coupling pin being inserted and welded to the through hole; And a channel-type horizontal bar having through holes formed on both sides of a central portion of the vertical bar are welded to each other.

In the present invention, the channel type horizontal bar is formed with inclined portions having inclined angles at predetermined positions on both sides, and inclined angles formed at certain positions on both sides are 10 to 20 degrees.

The present invention also provides a method of manufacturing a hollow bar, comprising: preparing a vertical bar by cutting a rectangular hollow bar to a predetermined length; Forming a through-hole at a predetermined position in the upper and lower portions of the prepared vertical bar; Preparing an engaging pin having a through hole formed at one end thereof; Fitting a coupling pin into the through-hole of the vertical bar, welding and joining the coupling pin; Preparing a horizontal bar by cutting the channel bar into a predetermined length; Forming an inclined portion on both sides of the horizontal bar at a predetermined position; Forming a through hole at a predetermined position of the horizontal bar; And welding the horizontal bar to both sides of the center of the vertical bar.

The present invention has the following effects by means of the solution of the above problems.

First, according to the present invention, since a channel horizontal bar is welded and coupled to a vertical hollow bar of a rectangular hollow, and the engagement pin is coupled to the through hole of the vertical bar, The workability of connection of the form panel is improved.

Secondly, according to the present invention, since the wedge pin is fastened to the coupling hole of the square panel and the through hole formed in the horizontal bar of the channel type, it is possible to smoothly cope with the side pressure of the concrete applied to the connecting portion of the form panel There is an effect.

FIG. 3 is a perspective view of the front perspective view of FIG. 1 as seen from the bottom; FIG.
FIG. 4 is a view showing a state of use of a mold fixture for building, which is an embodiment of the present invention. FIG.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a rear perspective view of a formwork fastener of the present invention, FIG. 3 is a perspective view of the front view of FIG. 1 viewed from the bottom, FIG. 4 is a perspective view of the formwork fastener of FIG. Fig. 2 is a view showing the state of use of the mold fastener of the invention.

As shown in FIGS. 1 and 2, the present invention is characterized in that a through hole 12 is formed at a predetermined position on the upper and lower sides, and a connecting pin 30 is inserted into the through hole 12, A vertical bar 10 and a channel type horizontal bar 20 joined to both sides of a central portion of the vertical bar 10. A horizontal bar 20 is formed on both sides of the center of the vertical bar 10 The method of joining is welding and welding.

The horizontal bar 20 of the channel type horizontal bar 20 is formed with a through hole 22 at one side thereof and the horizontal bar 20 of the form fastener 100 is inserted into the through hole 22, A wedge pin 50 is inserted to fix the wedge pin 50 to the base plate 20 and the horizontal bar 20 of the die fixture 100 is fixed to the engaging hole 40 of the die plate 40 by the wedge pin 50. [ And the form panel 40 is connected and fixed.

In order to facilitate handling of the mold fixture 100 and to improve the workability in connection and fixing of the mold panel 40, the channel horizontal bar 20 has a constant inclination angle a at certain positions on both sides An inclined portion 24 is formed.

Here, the inclination angle (a) of the inclined portion 24 is preferably 10 to 20 degrees in order to improve workability in connection and fixing of the formwork panel 40.

Next, a description will be made of a method of manufacturing a mold fastener for a building according to an embodiment of the present invention.
