Generally, when building and civil engineering structures are constructed, walls are formed by injecting concrete into a concrete injection space and curing it.

Such a mold requires a spacing device that maintains a gap between the pair of panels constantly until curing is completed. The molds are of the form of plywood, aluminum panels or steel molds A variety of spacing devices have been introduced.

Such a mold requires a spacing device that keeps a gap between the pair of panels constant until the curing is completed. The form is a form of plywood or an aluminum panel or a steel steel foam (gum) or a euro foam Depending on the type of formwork, various spacing devices are being introduced.

Conventional spacing devices can be represented by two types according to the type of the formwork panel to be used. Firstly, a gap keeping device used in a formwork assembly which is used by assembling a large number of small- 1a, a coupling hole is formed at both ends of the mold panel, and the pair of mold panels is coupled through the pair of mold panels so that the coupling hole is exposed to the outside of the mold panel, so that a separate coupling pin or the like is inserted into the coupling hole, Respectively.

That is, in the mold assembly having the gap maintaining device 3 according to the prior art 1, when the projecting portion of the gap maintaining device is inserted into the joint portion between the panel frames 2 of the Eurofoam panels 1, 3a to fix the gap holding device at the same time as the form panel is engaged.

After the curing of concrete is completed, the fixing pin is removed, the fixing member is separated, and the form panel is disassembled to complete the concrete structure.

In this case, in the conventional space maintaining apparatus, since the exposed portion formed with the coupling hole protrudes outside the concrete wall, it is necessary to cut all the protruded portions, so that the construction time is increased and the workability is deteriorated.

In order to secure a firm bonding force, the conventional spacer is usually made of a metal material such as steel.

In a wall exposed to the outside of a concrete structure, rainwater or the like penetrates through the gap of the cut-off bolts, and there is a problem of rusting.

Another conventional technique, as shown in Fig. 1B, is a gap maintaining device 6 (hereinafter referred to as " Prior Art 2 ") used in a gantry made of a large foam.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a spacing device for a mold assembly according to the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 2 to 5, the gap holding device 30, which is easy to fasten and separate according to the present invention,

An apparatus for maintaining a space between a pair of form panels (10) forming a space (S) in which concrete is placed,

A seperatel bolt 31 located in the installation space S and having a screw portion 31a at both ends thereof;

An exposed portion 34 which is connected to the corresponding thread portion 33 and is protruded to the outside of the formwork panel 10 and is fixed to the joist 20 of the panel 10, (32); And

A wedge member 38 for fixing the main body bolt 32 to the main thread member 20 through a slit hole 22 provided in the main thread member 20 and a slit hole 35 provided in the exposed portion 34, ). ≪ / RTI >

2 and 3, the form panel 10 is for forming a structure such as a wall, and typically, a pair of form panels 10 are spaced apart from each other, To prevent mutual expansion or deformation of the form panels 10 due to lateral pressure generated when the concrete is cured.

The form panel 10 includes a board 11 on which concrete is interposed and a panel frame 12 connected to the board 11 by bending outward on both sides of the board 11,

The hollow member 11 is formed with a through hole 11A through which the gap holding device 30 can be inserted or joined.

The board member 11 and the panel frame 12 may be integrally formed using an aluminum material or the like in order to attain light weight effect and durability at the same time,

Or a synthetic resin in which a foaming agent is mixed on the center portion to form micro pores, thereby ensuring a lightening effect. In addition, the foamed material is molded into a synthetic resin having no or little mixing of the foaming agent, A method in which the material is molded so as to have a predetermined elastic force can be considered.

The board member 11 and the panel frame 12 are integrally formed by a molding method such as extrusion and injection for the purpose of reducing manufacturing cost and are basically suitable for use as a molding panel in a synthetic resin such as foamed urethane In order to ensure the strength, the physical properties can be specified by mixing various additives such as a hardener.

As shown in FIG. 2, the panel frame 12 is used to couple the formwork panel 10 with the general panel 1,

The panel frame 12 is formed with two contact portions, i.e., an outer projection portion 13 and an inner projection portion 14, for fastening with ordinary panels 1,

And it is possible to prevent deformation due to concrete curing and to form a gap between the outer projecting portion 13 and the inner projecting portion 14 through engagement with the general panel 1 to thereby form a tool for disassembling or assembling For example, it is preferable to use a sucker foot drawing (so-called paruru) insertion.

The outer projecting portion 13 and the inner projecting portion 14 form a flat contact surface so as to be in close contact with the corresponding projecting portions 2a formed on the panel frame 2 of the general panel 1 to prevent the concrete from flowing out desirable.

3 and 4, a fastening hole 12A for fastening with other panels is provided in the panel frame 12 of the board member 11 along a vertical direction at predetermined intervals,

The form assembly can be fixed using a fastening pin (not shown) and a wedge pin (not shown) through the fastening hole 12A.

Also, when the side pressure is applied to the panels due to the generation of side pressure while the concrete is placed in the pouring space S formed by joining with the general panel 1, the joining of the panels may be deformed.

In order to prevent the above problems, the panel frame 12 of the present invention projects in the lateral direction from the outer projecting portion 13, as shown in an enlarged view of the lower side of FIG. 2, And an auxiliary protrusion 14 contacting the outer surface of the base 2a.

Since the auxiliary protrusion 14 is in contact with the corresponding protrusion of the general panel 1, frictional force is generated against the side pressure caused by concrete curing, thereby preventing deformation of the mold assembly.

As shown in the enlarged view of FIG. 2, the panel frame 12 is extended from the outer projecting portion 13 in the projecting direction of the panel frame 12 to open contact portions when the panels are disassembled, And a relieving protrusion 15 capable of relieving the receiving pressure is further provided.

That is, when disassembling the form assembly, the dissolving protrusion 15 is instantaneously pressed in one direction of the lateral direction of the board member 11 so that the frictional force acting on the contact surface between the outer protruding portion 13 and the corresponding protruding portion 2a is instantaneously The disassembling operation of the panel can be easily performed.

As described above, since the panel frame 12 can ensure a predetermined amount of elastic force, it is possible to eliminate the frictional force by pressing the dissolving protrusion 15.

Further, the expression of opening the contact portion encompasses the concept that the contact portion is finely dropped by momentary pressurization, so that the right of the present invention should not be excessively literally interpreted.

3 to 5, the main body bolt 32 is formed integrally with the corresponding threaded portion 33 and the exposed portion 34, and the exposed portion 34 is provided with a gap holding device And a slit hole 35 formed in the longitudinal direction so as to penetrate in a vertical direction and into which the wedge member 38 can be inserted. When the form assembly is installed, the corresponding threaded portion 33 is positioned in the installation space S After concrete pouring and curing, only the body bolt 32 including the corresponding thread portion 33 is separated from the concrete wall while being separated from the seperate bolt 31.

When the main body bolt 32 is removed, a hole corresponding to the space in which the corresponding screw portion 33 is embedded is formed in the concrete wall. Therefore, the screw portion 31a of the seperate bolt 31 is buried in the concrete wall, It is not necessary to remove the end portion of the septa bolt 31 projecting to the outside of the wall unlike the conventional spacing maintenance apparatus.

In addition, a separate stopper is inserted into the hole formed by separating the main body bolt 32 to be coupled to the threaded portion 31a of the seperate bolt 31, or the seperated bolt 31 is buried in the concrete with concrete or the like Rainwater or the like penetrates and the seep bolt 31 is rusted.

The threaded portion 31a of the septa bolt 31 is formed with a male screw thread and the corresponding threaded portion 33 of the body bolt 32 is formed on the inner wall surface with a female screw thread corresponding to the male screw thread, It is possible to assemble and separate the main body bolt 32 and the main body bolt 32, thereby making it possible to reuse the main body bolt 32.

The corresponding threaded portion 33 has a conical shape with a narrow width in the direction of engagement with the septic bolt 31,

It is preferable that the main bolt 32 is loosened and separated from the septa bolt 31 while the frictional force with the concrete is released.

Therefore, the present invention requires only the septa bolt 31 as a consumable material, and the configuration of another interval maintaining device can be reused, and therefore, it is highly available and versatile.

Next, as shown in FIG. 3 to FIG. 5, the nut portion 36 is introduced at the outer end of the exposed portion 34 so that the body bolt 32 can be easily fastened and separated.

The nut portion 36 is preferably made of a hexagonal nut like a conventional one by rotating the body bolt 32 by a tool such as a wrench or a wrench which is commonly used,

4, a tool insertion hole 23 is formed in the connection portion between the support plate 21 and the board member 11 so that the user can insert the tool. do.

The tool insertion hole 23 can be used for installing and dismounting the form panel 10 when the cabinets 20 and the form panel 10 are integrally formed.

The horizontal widths of the support members 21 and the connection plates 27 are equal to or slightly larger than the distances between the inner surfaces of the panel frames 12 of the form panels It is preferable to be coupled in a detent manner between the panel frames 12,

When the joist material 20 and the form panel 10 are used separately from each other, when the joist material 20 is joined or separated between the panel frames 12 of the form panel, the tool insert hole 23 is used You can work on it.

The tool insertion hole 23 may be formed by joining the joist 20 and then drilling the hole corresponding to the tool insertion hole 23 at the time of manufacturing the joist 20, 10). ≪ / RTI >

The tool insertion hole 23 can be used to disassemble the form panel 10 or the joist line 20 or all of them using the principle of leverage by inserting a disassembly tool or the like during disassembly work,

Furthermore, it has a function of securing a field of view so that the exposed portion 34 of the gap maintaining device 30 can be accurately inserted into the support hole 27A of the wiring material 20 during installation work.

Further, it is more preferable that the tool insertion hole 23 is provided on one or both of the upper and lower support plates to increase the workability.

The wedge member 38 is preferably formed to be equal to or slightly smaller than the length of the slit hole 22 and the slit hole 35. The wedge member 38 is formed to have a slit groove 22 and a slit groove 22 so that the wedge members 38 are not separated from the slit grooves 22 and the slit holes 35 after the wedge members 38 are inserted.

The tail portion of the wedge member 38 is formed to have a tip end portion 38b so as to smoothly enter the slit groove 22 or the slit hole 35 for the first time.

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

The wedge member 38 may be borrowed from a commonly used wedge pin commonly used in a construction site in order to reduce the manufacturing cost and ensure the versatility.

The wedge member 38 is struck to fix the gap holding device 30 while being fitted to the exposed portion 34 of the gap holding device 30 according to the present invention to secure the gap between the form panel 10 ) And the interval between them,

Since the wedge member 38 can be engaged and separated through the blow of the tool, the working time can be remarkably shortened as compared with the prior art.

Next, referring to Figs. 2 to 6, the installation and disassembly operation of the space holding device for a mold assembly according to the present invention will be described. For convenience of explanation, an example in which the joist material 20 is used in a state of being coupled to the formwork panel 10 will be described as an example.

The user first joins the form 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 foam that fits the width of the wall.

The form panel 10 and the general panel 1 can be arranged in a zigzag arrangement as well as being arranged in a line when the large foam is manufactured so that the coupling and supporting force between mutually contacting panels can be increased to effectively counter side pressure have.

In addition to using the form panel 10 and the general panel 1, it is also possible to connect the form panels 10 of the present invention to each other to form a large-sized foam. In this case, the panel frame 10 of the form panel 10 The dice panel 10 without the auxiliary protrusions 14 or with the auxiliary protrusions 14 removed therefrom will be utilized.

The manufactured large-size foam is installed at a predetermined spacing so that the plate members 11 are opposed to each other in the installation place, and a pouring space S is formed in the space therebetween,

The user passes the gap holding device 30 in a state in which the septa bolts 31 and the body bolts 32 are coupled through the through hole 11A of the board member 11 and the support hole 27A of the wire rope 20, .

At this time, if it is difficult to insert the space holding device 30 because the positions of the corresponding supporting holes 27A or the through holes 11A are not aligned with each other, So that it can be forcedly inserted.

The gap holding device according to the present invention is inserted into a form panel in a coupled state or inserted into a panel by inserting the other side of the bolt into the panel in a state where the bolt is coupled to one side of the inner panel and then inserting another bolt into the opposite panel To be combined with each other.

The exposed portion 34 of the main body bolt 32 is formed to have a length wider than the width of the connecting member 27 between the board member 11 and the wiring member 20, And the operation of separating the main body bolt 32 using the nut portion 36 to be described later is not restricted.

After the insertion of the gap maintaining device 30 is completed, the slit grooves 22 of the wire 20 and the slit holes 35 of the exposed portion 34 are aligned with each other, and then the wedge members 38 are inserted into the slit grooves 22, Is inserted into the slit hole (35) to complete the connection of the gap holding device (30) and the installation of the molding assembly.

When the curing is completed after the concrete is poured into the pouring space S, the nail portion 36 protruding outside the connecting plate 27 of the joist material 20 is inserted into the body bolt 32 using a tool, Only the seperate bolts 31 are separated from each other and the panels are disassembled to complete the construction of the wall.

At this time, it is impossible to manufacture a large-sized foam that can cover all the walls in the case of construction of a high-rise building,

Since the slab construction is performed simultaneously between the respective layers or after the wall construction is completed,

A large foam having a predetermined height (for example, a height of one layer) is manufactured to complete the wall, and then the main body bolt 32 is separated from the main body. Then, the large foam itself is disassembled from the wall and carried to a crane, It is preferable to be utilized in such a case.

The body bolt 32 can be reused as described above when installing the wall by using the installation and disassembly of the large foam itself. However, when the main body bolt 32 is separated from the body bolt 32, There is a possibility of loss of labor, waste of labor power due to transportation of the main body bolt 32, increase of working time, and the like.

6, when the main body bolt 32 is separated from the seperator bolt 31, the corresponding screw portion 33 is exposed to the outside of the connecting plate 27 of the long-term lead material 20 The wedge member 38 is held in the slit grooves 22 and the slit holes 35 in a state where the wedge member 38 is inserted into the slit holes 35, thereby solving the above problem.

In other words, since the body bolt 32 of the present invention is formed such that the length of the exposed portion 34 is equal to or longer than the width of the plate member 27 and the plate member 11, The exposed portion 34 is inserted into the support hole 27A of the connection plate 27 and the slit groove 22 is inserted into the support hole 27A in a direction opposite to the installation direction of the mold assembly, The wedge member 38 used in the state in which the slit hole 35 is aligned with the slit hole 35 is inserted into the slit groove 22 and the slit hole 35 so that only the body bolt 32 can be fixed there is,

It is not necessary to separately store or separate the body bolt 32 and the wedge member 38, which are separately formed at the time of carrying the large foam itself or each of the panels, thereby shortening the wall construction time and reducing labor.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the present invention is not limited to the described exemplary embodiments, but various modifications, alterations, and changes may be made by those skilled in the art.
