The installation process and operation effect of the formwork fixing device of the first embodiment of the present invention made in this way will be described as follows.

The installation process of the first embodiment of the present invention will be described assuming a state in which the side formwork SP and the corner formwork CP are arranged in a rectangular column shape, as shown in FIGS. 1 and 10 .

First, the operator rotates the first fixing bolt part 155 of the first fixing part 151 to loosely adjust the gap between one end of the frame 111 and the first body 153 of the first fixing part 151 . . And the operator pulls the extension member 175b of the second fixing part 171 so that the fixing pin 175a is separated from the fixing hole part 111b of the frame 111 . In this state, the operator moves the second body 173 of the second fixing part 171 in the longitudinal direction of the frame 111 . At this time, the operator holds the extension member 175b at a position where the end of the first position retaining pin 157 and the end of the second position retaining pin 177 are at least greater than the width of the side formwork SP. ) is placed. Then, the fixing pin 175a is inserted into one of the fixing holes 111b of the frame 111 by the elastic force of the elastic member 175c of the second fixing part 171 . The interval between the first position retaining pin 157 and the second position retaining pin 177 is at least the width of the side formwork (SP) plus the thickness of the corner formwork (CP) in contact with both sides of the side formwork (SP). to maintain the ideal.

In this state, the operator attaches the first position retaining pin 157 coupled to the first fixing part 151 and the second position maintaining pin 177 coupled to the second fixing part 171 to the wedge of the corner formwork (CP). It is placed in the pinhole portion (h). Then, the operator rotates the first fixing bolt part 155 by inserting it into the tool insertion part 155c of the first fixing part 151 using a tool such as a skewer. Then, the screw thread portion 155a of the first fixing bolt portion 155 is guided to the screw groove portion 111a of the frame 111 and rotates while the frame 111 and the first body 153 of the first fixing portion 151 are rotated. reduce the spacing of Then, the distance between the first position holding pin 157 and the second position holding pin 177 is also reduced. And the first position retaining pin 157 and the second position retaining pin 177 fix the corner formwork CP and the side formwork SP while penetrating the wedge pin hole h of each corner formwork CP. .

That is, the first position retaining pin 157 and the second position retaining pin 177 pass through the wedge pin hole portion h of the corner formwork CP and are formed on both sides of the side formwork SP through another wedge pinhole portion ( h) is inserted through it.

The operator may sequentially install the fixing member assemblies 101 , 103 , 105 , and 107 on each of the four surfaces of the tetragonal pillar in this way. In addition, the operator may install the fixing member assemblies 101 , 103 , 105 , 107 at various heights. Even if an operator works in the process of installing the fixing member assemblies 101, 103, 105, and 107, the first position retaining pin 157 and the second position retaining pin 177 are attached to the corner form (CP). It can be easily inserted into the wedge pin hole (h) of the Of course, the operator can easily install the fixing member assemblies 101 , 103 , 105 , and 107 while repeatedly installing the fixing member assemblies 101 , 103 , 105 , and 107 at a predetermined height even when installing from a high position.

That is, the frame 111 is subjected to a force at a short distance to prevent the bending phenomenon in which the frame 111 is bent. As such, the frame 111 prevents the bending phenomenon and prevents the frame 111 from being bent even when the fixing member assemblies 101, 103, 105, and 107 are installed or when concrete is poured, so that the column can be precisely constructed. .

Subsequently, the operator connects the corner fixture 201 to the fixing member assembly 101 and another fixing member assembly 103 disposed adjacent thereto. That is, the operator hooks the support part 215 of the corner fixture 201 to the first locking part 113 of the fixing member assembly 103 (for convenience of description, the same reference numerals as those of the fixing member assembly 101 are given). Then, the operator inserts a tool such as a skewer into the tool insertion portion 219b of the tightening portion 219 of the corner fixture 201 and rotates it. Then, while the screw thread portion 219a of the tightening portion 219 is rotated along the screw groove portion 217a of the connecting portion 217, the end of the tightening portion 219 is the second fixing portion 171 of the fixing member assembly 101. ) is in close contact with the support surface 179a of the second locking part 179 installed in the . Accordingly, the corner fixture 201 connects the fixing member assembly 101 and the other fixing member assembly 103 disposed adjacent thereto from the corner formwork CP side by tightening in a pulling direction to each other.

The operator installs the remaining corner fixtures 203, 205, and 207 in the same manner as described above to connect the fixing member assemblies 101, 103, 105, and 107 in the form of one band. Of course, the operator installs the respective corner fixtures 201, 203, 205, and 207 in the same manner as described above for the fixing member assemblies 101, 103, 105, and 107 installed at different heights.
