Description

{FIXING APPARATUS FOR MOLD PANEL}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold fixture, and more particularly, to a mold fixture used to extend a new wall above an already formed wall.

Generally, a concrete wall is a concrete wall which is supported by soil on one side of a tuff and on the other side when a form is installed on both sides in a subway construction.

The concrete wall is constructed by placing the concrete in the direction opposite to the soil on the terraced ceiling, then installing the concrete wall on the outer wall of the concrete, and placing the concrete in the space formed by the soil and the form do. At this time, the joint wallpaper zone is fixed to one end of the anchor bolt embedded in the floor concrete, thereby preventing the form from being pushed out due to the concrete pouring.

As in the case of such a composite wall, there is used a device for supporting a formwork in the construction of a concrete structure, which comprises a vertical support vertical to the ground, a lower end fixed to the vertical support, And a plurality of reinforcing bars coupled between the vertical support and the inclined support so as to connect the free ends of the vertical support and the horizontal support to each other.

In this regard, the Korean Registered Utility Model No. 20-0381406 discloses a " support for fixing a form ", specifically, a slope regulating plate having a predetermined width and length at the end of a horizontal support, A slant fixing plate is formed on the upper end surface of the end surface of the ground contact plate and the upper surface of the upper end of the vertical support plate so as to be fixedly supported by a second slant support base having both end portions connected to the slant fixing plate. A sufficient grounding area can be ensured while maintaining the vertical state of the vertical support regardless of the vertical position of the vertical support.

On the other hand, when the height of the concrete concrete wall is relatively high, there is a possibility that the entire wall can not be laid at one time. At this time, a certain portion of the concrete wall is formed first and the new concrete wall is extended on the formed concrete wall Construction can be done in a way.

In this regard, the Korean Registered Utility Model No. 20-0167204 discloses "a device for supporting a concrete wall formwork ", specifically, a support for supporting the formwork for a wall in a substantially vertical phase, a support rod for supporting the support, And a bracket connected to the brace bar by being fixed at a position spaced a certain distance from the side of the brace. The bending part fixed to the concrete bracket by an anchor or the like is formed at one side of the bracket, A pair of protrusions are formed on the inner side so as to be assembled to the other ends of the support rods and a pair of pedestals integrally connected to the bottom surfaces of both side ends of the support rods are integrated. The struts can be placed on the support rods and installed up to the upper part of the underground space, The side lifting a concrete hapbyeok, the other side, discloses the subject to be supported by a solid and stable base of the pair.

However, in the case where the concrete sidewall is installed in two stages, it is inappropriate to use the devices of the above-described type when the height of the newly formed wall (upper wall) is relatively low And it is very inefficient because only a part of the form can be used even if it is installed). Therefore, development of a device therefor is required.

In addition, when a small-sized concrete wall is required to be installed, it is required to develop a device capable of forming a concrete wall more quickly and easily, and a device capable of firmly supporting the formwork even when the thickness of the used formwork is uneven Development is required.
