Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a corner tie bracket for fixing a corner portion of a formwork when constructing a concrete structure, and more particularly, to a multi-corner tie bracket capable of structurally and firmly fixing a corner portion of a formwork .
In general, a formwork is a general form of a formwork panel for forming a structure by pouring concrete and a platform for holding the panels in an accurate position. The concrete is kept in a constant shape and dimensions, It is used for the purpose of proper curing of concrete by preventing the leakage of air and preventing the influence of outside air.
For this purpose, when a large concrete structure such as a retaining wall or a bridge pier is conventionally used, a form panel made of wood, plywood or metal is mainly used. However, recently, when a concrete wall is constructed, a unit panel formed by connecting a plate- A method of forming a mold for an inner wall and an outer wall by assembling the mold, filling the space between the mold with the reinforcing bar and concrete, curing it, and removing the mold are widely used.
Particularly, in the construction of the outer wall of the concrete structure, the corner portion where the wall surface of the outer wall is in contact with the wall surface is usually maintained at a right angle. Due to the corner portion forming such a right angle, there was.
As a method that has been conventionally used, a plate form on which a wall surface is laid without using a separate corner form is aligned so that its both ends are perpendicular to each other, and then these are fixed with a separate fixing member, i.e., a corner tie bracket ), And so on.
FIG. 1 is a view showing a state where a corner portion of a form is fixed through a corner tie bracket when a concrete main tower of a conventional bridge is constructed.
As shown in FIG. 1, a conventional

In addition, when the angle of the corner of the wall to be installed is designed to be an obtuse angle greater than 90 degrees or an acute angle smaller than 90 degrees, the shape of the
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a corner tie bracket, So that it is structurally robust and can be fixed easily.
According to an aspect of the present invention, there is provided a multi-corner tie bracket comprising: a fixing part fixed to a mold frame; A rotary member rotatably coupled to one side of the fixing unit; A tie rod coupled through the rotating member; And a fastening member fastened to the tie rod and closely held on the outer surface of the rotary member.
The fixing unit includes a fixing plate fixed to the mold frame, a support plate coupled to the fixing plate and closely supported on the outer surface of the mold frame, a support surface coupled to the support plate, And a vertical plate formed thereon.
At this time, the rotating member may have a circular outer surface, and the supporting surface may have a curved surface shape corresponding to the outer surface of the rotating member.
The tie rod may be installed perpendicular to the central axis of the rotary member.
The support plate may have a through hole through which the tie rod passes.
At this time, the through-hole may be formed long in the front-rear direction of the support plate so that the tie rod can be freely changed in angle.
The vertical plate may be coupled to the support plate in a state where a pair of the vertical plates are disposed parallel to each other with the through hole interposed therebetween.
Further, a spacing member may be provided between the pair of vertical plates.
According to the multi-corner tie bracket structure of the present invention having the above-described configuration, even when a situation occurs in which the angles of the corners where the molds on both sides meet at the time of the mold work are not exactly perpendicular to each other, It is advantageous that the working surface of the force acting in the direction and the working surface of the force are always vertical so that the mold corner portion can be firmly and stably fixed.
In addition, since it is not necessary to change the shape of the base of the corner tie bracket according to the angle formed by the corner portion of the mold as in the conventional art, there is an advantage that the time and cost can be greatly reduced.
In addition, there is an advantage that it is possible to perform the fixing operation of the mold corner part through the single multi-corner bracket easily and quickly regardless of the corner angle formed by the mold.
