Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an anti-

More particularly, the present invention relates to an apparatus and method for preventing deformation of a brace for a formwork and a reinforcing bar to prevent a brace provided on the outside of the form from being transmitted, ≪ / RTI >

Generally, a concrete form is maintained in a straight form and a form, so that a long bracket is installed in the lateral direction on the outer surface of the formwork so that any form does not protrude to the outside.

Therefore, a brace support is provided on the form to support the braces so that the braces do not fall out of the form.

However, since the support bracket is detachable from the frame, it is necessary to attach the bracket when installing the bracket and to remove it when removing the bracket, so that it is troublesome to install and dismount the bracket and the bracket is installed at a predetermined position of the die, There was a drawback that it was very inconvenient to use.

In order to cast concrete during the construction of the building, concrete is poured into the mold to form a frame, and when the concrete is hardened, the form is separated. In order to prevent the concrete from being pushed outward due to the internal pressure of the poured concrete, A fixing support member is installed and fixed.

The above-mentioned support member for fixing the formwork is composed of a support base, a fixing base and a brace, and the connection and disassembly of the support base, the fixing base and the brace are simplified, thereby facilitating the installation and disassembly of the formwork.

As shown in FIG. 1, each of the connecting members is assembled by a combination of a bolt and a nut.

A through hole is formed in each of the assembling parts of the support frame 2 and the support frame 3 so that the support frame 1 can be fixed to the floor surface with the wedge nail, The bolts 7 are inserted into the through holes in accordance with the through holes of the brace 1 and the brace 3 and are passed through the through holes so that the nuts are fastened to the ends of the bolts 7 exposed to the outside of the through holes, The support member is assembled.

However, as shown in FIG. 1, the conventional support member for fixing a mold as described above has a structure in which the position of the through hole formed in the support base 2, the brace 3, and the fixture 1 to insert and assemble the bolts 7 It is difficult to match the through holes and the thread of the bolt 7 is caught by the entrance of the through hole so that the bolt 7 is tightened by tightening the inserted bolt 7 without easy insertion and separation. So that the productivity is deteriorated.

Such conventional braces for supporting formwork and reinforcing bars have the risk of accidental conduction of the walls due to sliding of the braces, which prevents conduction of the form due to omission of the bottom wedge during high walled frame and reinforced concrete work.

In addition, there is a problem that a safety accident such as a fall of a worker due to a foot being walked by a worker due to long-term maintenance of a plywood wedge supporting the pipe brace occurs.

That is, in the conventional form bracing, when the plywood is supported on the bottom of the bracing, the bracing rod is supported by a nail or the like so that the bracing rod is not slid. After the bracing is removed, An accident occurs, and a safety accident that an operator falls and hurts is generated.

For example, Patent Document 1 below discloses a 'fastening brace for a form'.

The fastening bracing frame according to the following Patent Document 1 has a flange formed at a joint portion of a concrete form and a joint hole at a flange formed at one side between the joint holes, and a longitudinal hole is formed at the insert portion to sandwich the wedge pin A bolt is provided so as to protrude in a direction orthogonal to the form clamping pin at the outer engaging jaws of the form fastening pin and the form fastening pin so that the upper end of the bolt becomes the receiving portion and the lower portion of the receiving portion has the guide protrusion.

A "b" type brace strap is provided on the outside of the brace bracket, a hole is drilled in the vertical strap of the brace strap, the bolt is inserted, and the tightening nut is screwed from the outside.

A guide hole is formed in the horizontal plate so that a lower guide protrusion of the pedestal mount portion is engaged and the pedestal strap is slid along the bolt length direction and a hinge shaft connection pipe is formed outside the lower end of the pedestal strap, Hinge the top hinge axis of the left thread rod.

The lower end of the left-hand thread rod is screwed to the upper side of the buckle having the screw holes formed at the upper and lower ends thereof, the turnbuckle type brace screwed to the lower side screw hole of the buckle and the hinge shaft connection pipe of the fixed plate to the lower side hinge shaft of the right screw, And a fixing plate formed with a nail hole and a groove portion.

The following Patent Document 2 discloses a 'strut support for a concrete form'.

The strut support member for a concrete form according to the following Patent Document 2 is a concrete form attached to the outer periphery of a rectangular plate body so that a certain height protrudes from the surface of the plate body at right angles to the surface of the plate, And a pedestal formed in a plane with the plate body and having a predetermined height at the upper end of the plate body so as to be perpendicular to the plate body and coupled to the lower end of the concrete form as a fastener.

A through hole penetrating through the upper edge of the lower end of the concrete form and a width corresponding to the bottom width of the brace, the inner bottom surface having a diameter corresponding to the diameter of the through hole toward the through hole A rotation shaft having a length corresponding to the length of the through hole is formed to form a male screw bolt at a lower end of the rotation shaft and an extension is formed at an outer end thereof.

A bracket supporting portion formed at an inner side of the protrusion by forming a protrusion having a length corresponding to the height of the bracket vertically at the end of the protrusion, a rotating shaft of the bracket supporting member is inserted into the through hole, Install the washer and flat washer and screw the retaining nut so that the strut supports rotate in the middle of the bottom of the concrete formwork.
