Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a spacer for fixing a mold,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a spacing holder for fixing a mold for constructing a structure, and more particularly to a spacing holder for holding a mold for fixing a mold, And a mold structure using the same.

Typically, the form is constituted by a pair of opposing panels for forming a wall or the like of the building, so that the concrete can be installed between the pair of panels.

On the other hand, an isolation member such as a seperator or a seperatel is used between the pair of panels so as to keep the interval constant.

The isolator is fixed to the outside of the mold through a fixing member such as a fin.

In order to engage with the fixing member, joint portions formed at both ends of the isolation member protrude to the outside of the formwork, and the rest except the protruding ends are embedded inside the concrete.

Therefore, when the concrete is cured and the form is dismantled, it is troublesome to cut the end of the insulating member protruding to the outside of the concrete.

In addition, the fixing member coupled with the isolating member must be fixed to the inner and outer panels of the mold using washers and nuts, respectively, and the dismantling must be performed in the reverse order of the fixing operation.

In addition, the conventional mold panels require a long time to be manufactured due to the use of the wood panel, and most of them are damaged in the process of removing the mold after the curing of the concrete is finished, It is troublesome to install it.

In order to solve the problem of the above-mentioned wood panel, dies having both inner and outer dies are used. Since the inner and outer molds are all made of a metal material, the mold is advantageous in that it can be reused repeatedly and can be used as a scaffold.

However, in order to fix the above-mentioned wood and metal panels with the isolating member, it is necessary to drill the hole every time the installation is performed, so that the life of the mold is short and the reuse limit is not overcome.

Korean Registered Utility Model No. 20-0458451 (Registered on January 31, 2012) Korean Public Utility Model No. 20-2010-0008813 (Released on September 6, 2010)

The vertical member 320 serves to connect the panels 310 connected to both ends and to serve as a bracket to which the interval holder 100 described above is connected.

Meanwhile, the vertical member 320 may be made of steel to vertically reinforce the panels 310 fastened to both sides.

In addition, the vertical member 320 has the same height as the panel 310, has a relatively narrow width as compared with the panels 310, and can be positioned alternately with the panel 310.

At this time, through-holes are formed in the side walls of the panel 310 and the vertical member 320 at regular intervals along the vertical length direction, thereby forming the formwork 300.

Subsequently, the vertical member 320 is formed into a flat plate so as to form a planar wall of the structure, and is formed in a beam shape whose other surface is open so that the cross section has a substantially 'C' shape, A through hole 321 is formed.

The first through hole 321 is for inserting the gap holding tool 100 described above. The gap holding tool 100 is inserted through the first through hole 321 formed in two vertical members facing each other and fixed The gap between the molds 300 on both sides can be maintained.

The vertical member 320 has a hollow coupling block 100 to allow the gap holder 100 passing through the vertical member 320 to be coupled to the vertical member 320 through the fixing members 200 and 210. [ (330).

The coupling block 330 includes a second through hole 331 formed to correspond to the first through hole 321 and a plurality of partition walls 332 forming a space for insertion of the fixing members 200 and 210 ).

(a), the long fitting member 120 is provided with the first through hole 321 of the vertical member 320 and the second through hole 321 of the coupling block 330 facing the mutually facing isolation members 110 at both ends, After passing through the through hole 331, the long connection member 120 is screwed to both ends of the isolation member 110. At this time, the position of the long fitting member 120 can be adjusted in the process of screwing.

After the partition wall 332 of the coupling block 330 is inserted between the first fixing portions 201 of the fixing member 200 and the first insertion groove 203 of the first fixing portion 201 is inserted The fastening member 200 and the spacer 100 can be completely fixed to the coupling block 330 by being seated in the coupling groove 121 of the long fitting member 120.

Similarly, the fixing member 200 and the gap holder 100 are completely fixed to the coupling block 330 in the same manner in the opposite side vertical member 320 facing the vertical member 320, 320 may be maintained.

As described above, when the gap between the vertical members 320 is maintained, the panel 310 is coupled to both sides to complete the formwork 300, and then the concrete is cured by pouring the concrete.

4 (b) shows a state in which the long fasteners 120 and the mold 300 are separated from each other in the isolating member 110. As shown in FIG.

That is, after the curing of the concrete is completed, the threaded portion of the separating member 110 and the long fitting member 120 is separated and the disassembling operation of the die 300 is performed while the long fitting member 120 is coupled to the die 300 .

At this time, the empty space generated by separating the isolation member 110 and the long fitting member 120 is buried with mortar or the like to perform the finishing work.

The separating member 110 is installed in a state of being embedded in the concrete and includes a long fitting member 120 separated from the separating member 110, a fixing member 200, a panel 310, a vertical member 320, Can be recycled again.

Although not shown in FIGS. 1 to 4, the isolation member 110 may have a circular flange-shaped engagement protrusion along the periphery of the long fitting member 120. This is because after the curing of the concrete is completed, 110 and the long fitting member 120 can be easily separated from each other, thereby improving the speed of disassembling work and the working efficiency.
