The formwork panel 10 includes a board member 11 to which concrete is interviewed, and a panel frame 12 bent outwardly on both sides of the board member 11, and

The null member 11 has a through hole 11A formed therein through which the gap retaining member 30 is inserted and coupled or separated.

The null member 11 and the panel frame 12 may be integrally formed using an aluminum material, etc. to simultaneously obtain a lightening effect and a guarantee of durability.

Alternatively, it is molded integrally with a synthetic resin mixed with a foaming agent on the center to form micropores to secure a lightening effect, and at the same time, the foam is not mixed or a small amount of synthetic resin is molded so that the particle composition is dense and hard. The manner in which it is molded to have a predetermined elastic force can be considered.

The board member 11 and the panel frame 12 are preferably integrally manufactured by molding, such as extrusion or injection, in order to reduce manufacturing costs. Basically, the board member 11 and the panel frame 12 are suitable for being used as a formwork panel in a synthetic resin such as urethane foam.

The tool insertion hole 23 can be used to dismantle the formwork panel 10 or the joist wire 20 or both by using a principle of a lever by inserting a dismantling tool or the like during the dismantling operation.

In addition, during the installation operation has a function to ensure the field of view so that the exposed portion 34 of the gap holding member 30 can be accurately inserted into the support hole (27A) of the joist wire 20.

And the tool insertion hole 23 is more preferably provided in any one or both of the upper, lower support plate to increase the workability.

Subsequently, as shown in FIG. 4, the wedge member 38 is inserted through the slit groove 22 of the joist wire 20 and the slit hole 35 of the main body bolt 32, thereby maintaining a spacing member ( 30) is fixed to the Jang wire (20), that is, the formwork panel 10 to maintain the spacing of the formwork panel 10, as well as to respond to the side pressure according to the concrete placing and curing.

The wedge member 38 is preferably formed to be the same as or smaller than the length of the slit groove 22 and the slit hole 35, the slit groove 22 and the slit groove (on both sides of the head 38a) The exposed portion wider than the length of 22 to prevent the wedge member 38 from being separated from the slit groove 22 and the slit hole 35 after insertion.

The tail portion of the wedge member 38 has a tip portion 38b so that the first entry into the slit groove 22 or the slit hole 35 can be made smoothly.

The wedge member 38 may be manufactured separately and used in the formwork assembly of the present invention,

In order to reduce manufacturing cost and secure versatility, it can be used as a wedge member 38 by borrowing a commonly known wedge pin commonly used in construction sites.

According to the present invention, the gap holding member 30 is fixed by being hit by the wedge member 38 and being fitted to the exposed portion 34 of the long wire member 20 and the gap maintaining member 30 to fasten the die panel 10. And to maintain the interval,

Since the wedge member 38 can be coupled and separated through the impact of the tool, the working time can be significantly shortened compared to the prior art.

Next, with reference to Figures 2 to 6 will be described the installation and disassembly operation of the formwork assembly having a spacing member easy to fasten and detach according to the present invention. For convenience of description, it will be described by representing the example that the wire rod 20 is used in a state coupled to the formwork panel 10.

First, the user combines the formwork panel 10 and the general panel 1 through the

fastening holes

12A and 2a of the panel frames 12 and 2 to produce a large form that fits the width of the wall.

In the production of large foam, the formwork panel 10 and the general panel 1 can be arranged not only in the same line, but also be arranged in a zigzag manner, so that the panels can be effectively joined to the side pressure by increasing the bonding and supporting force between the panels. have.

In addition, as well as using the formwork panel 10 and the general panel (1) can be utilized as a large form by interconnecting only the formwork panel 10 of the present invention, in this case, the panel frame of the formwork panel 10 ( 12, the formwork panel 10 without the auxiliary protrusions 15 or without the auxiliary protrusions 15 will be utilized.

After installing the large foam produced at a predetermined interval so that the board member 11 to face each other in the installation place to form a pouring space (S) in the space therebetween,

The user passes the gap retaining member 30 in the state where the sepa bolt 31 and the main body bolts 32 are coupled through the support hole 27A of the long wire member 20 and the through hole 11A of the null member 11. To assemble.

At this time, if it is difficult to insert the gap retaining member 30 due to a problem such that the positions of the supporting holes 27A or the through holes 11A do not coincide with each other, the protruding hitting part 37 of the body bolt 32 is tooled. You can force the hit with.

The gap retaining member is inserted into the formwork panel in a coupled state or by inserting the other side of the Sepha bolt into the panel while the main body bolt is coupled to one side of the inner rod, and then the other main body bolt is inserted into the opposite formwork panel to be mutually coupled. You can do that.

At this time, the exposed portion 34 of the body bolt 32 is formed to have a length wider than the width of the connecting member 27 of the null member 11 and the joist wire 20 hitting the projecting hitting portion 37 And the separation operation of the body bolt 32 using the nut portion 36 to be described later is not limited.

When the insertion of the gap retaining member 30 is completed, the slit groove 22 of the long wire member 20 and the slit hole 35 of the exposed portion 34 are aligned, and then the wedge member 38 is disposed on the slit groove 22 and the It is inserted into the slit hole 35 to complete the coupling of the space keeping member 30 and the installation of the formwork assembly.

When the mold assembly is completed in this way, after the concrete is poured into the pouring space (S), when the curing is completed, the nut part 36 protruding to the outside of the connecting plate 27 of the joist wire 20 using a tool bolt 32 After the bay is separated from the Sephabolt 31, the construction of the wall is completed by dismantling the panels.

In this case, in the case of construction of high-rise building, it is impossible to manufacture large foam that can cover all walls.

Since the slab construction is performed at the same time between each floor, or after completing the wall construction, the slab construction is performed,

After constructing a large foam having a predetermined height (for example, the height of one floor) and completing a wall, the large foam itself is dismantled from the wall in a state where only the main bolt 32 is separated, and then transported to a crane or the like to construct the next wall. It is desirable to make use of it.

In addition, when the wall construction by using the installation and disassembly of the large foam itself, as described above, the main body bolt 32 is reusable, a large number of main body bolts 32 in the state of removing only the main body bolt 32 If not separately stored there is a risk of loss, as well as waste of labor and work time due to the transport of the body bolt 32 may be a problem.

Thus, as shown in FIG. 6, when the main body bolt 32 is separated from the Sepha bolt 31, the corresponding screw part 33 is exposed to the outside of the connecting plate 27 of the joist wire 20. The above problems can be solved by inserting the wedge member 38 into the slit groove 22 and the slit hole 35 in a state.

That is, the main body bolt 32 of the present invention, as described above, the length of the exposed portion 34 is formed to have a length equal to or greater than the width of the null member 11 and the connecting plate 27, the main body bolt Unlike in the installation work of the form assembly, 32 is inserted in the opposite direction, that is, the exposed portion 34, not the corresponding screw portion 33, into the support hole 27A of the connecting plate 27, and the slit groove 22 And the wedge member 38 used in the state in which the slit hole 35 is aligned and inserted into the slit groove 22 and the slit hole 35 to fix only the main body bolt 32 to the joist wire 20. there is,

It is not necessary to separately store the main body bolt 32 and the wedge member 38 or separately transport the large foam itself or each panel when transporting the wall construction time and has the effect of reducing labor.

In the above description of the present invention with reference to the accompanying drawings, a form assembly having a spacing member that is easy to fasten and remove having a specific shape and structure has been described with reference to the present invention various modifications, changes and substitutions by those skilled in the art It is possible that such modifications, changes and substitutions should be interpreted as falling within the protection scope of the present invention.
