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 corner tie bracket 80 is installed on a mold frame 20 supporting a rear portion of a mold panel 10, which is formed for forming an outer wall corner portion of a concrete pillar.

That is, the mold frame 20 is connected to the rear part of the both side mold panels 10 to be in contact with each other at right angles to each other through the timber beam 12, and the corner tie brackets 80 So that the both-side corner tie bracket 80 is connected to the tie rod 60 and fixed.

The tie rods 60 penetrating between the both side pedestals 40 in a state where the triangular shaped pedestal 40 provided on the both side corner tie brackets 80 are fixed tightly to the outer surface of the side mold frames 20, The wing nut 50 is fastened to the triangular pedestal 40 so as to be closely attached to the outer surface of the triangular pedestal 40 so that the corner portions of the both side panel 10 can be firmly fixed.

However, when the fixing operation of the mold corner portion is performed using the conventional corner tie bracket 80 structure as described above, when the corner portions between the side mold frames 20 are precisely perpendicular, the fixing operation of the corner portion is relatively smooth The wing nut 50 can not be firmly brought into close contact with the outer surface of the pedestal 40 because the pedestal 40 is inclined by the angular deviation when the two formwork frames 20 are not exactly orthogonal to each other .

As the wing nut 50 is fixed to the outer surface of the pedestal 40, the wing nut 50 is structured to be unstably fixed. As a result, when the concrete 30 is poured into the formwork panel 10, There is a problem that the form panel 10 is pushed outward due to the load of the mold 30 and consequently the quality of the construction is deteriorated.

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 pedestal 40 is changed and changed according to the angle of the corner of the formwork. Therefore, there is a problem that the workability is significantly deteriorated, and the time and cost according to the hypothesis of the form can be excessively consumed.
