And more particularly, to a form panel which is spaced apart to form a concrete placement space and in which the spacing of the placement space is maintained through a gap holding member, wherein the gap holding member penetrating through the board member A pair of support plates having a slit groove through which a wedge member for fixing a gap holding member to a long side of the board member is connected to the outside of the board member, The present invention relates to a mold panel in which a gap retaining member is fastened to a long reinforcement member including a long reinforcement member composed of a connection plate having a support hole for supporting a member.

Particularly, according to the present invention, since the tie-line material supports the board member against the side pressure of the concrete and is used as a fixing means of the gap holding member, it is easy to fasten the gap holding member and the structure is simple, .

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 member which keeps a gap between the pair of panels constantly until curing is completed. The form may be a mold formed of a plywood, an aluminum panel, a steel mold, Various spacing members have been introduced depending on the type of the form.

Conventionally, spacing retention members can be represented by two types according to the type of a form panel to be used. First, a spacing retention device (referred to as the prior art 1) used in a form assembly 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.

The tool insertion hole 23 can be used for installation and disassembly of the formwork panel 10 when the joist material 20 and the formwork panel 10 of the present invention 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 mold panel 10 of the present invention are used in a separated state and the joining material 20 is joined or separated between the panel frames 12 of the form panel, Can be used.

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). &Lt; / 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 member 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.

As shown in FIG. 5, the panel frame 12 is used to connect the panel member 10 of the form 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 includes an auxiliary protrusion 14 protruding laterally from the outer protrusion 13 and contacting the outer surface of the corresponding protrusion 2a of the general panel 1, .

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 to prevent the panel frame 12 from being deformed.

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 gap holding member 30 includes a seperate bolt 31 having both side threaded portions 31a and positioned in the pouring space S and embedded in the concrete,

And a body bolt 32 connected to the exposed portion 34 and composed of a corresponding threaded portion 33 which is positioned in the pouring space S and to which the threaded portion 31a is coupled.

The body bolt 32 is formed integrally with the corresponding threaded portion 33 and the exposed portion 34 so that the exposed portion 34 is formed in the longitudinal direction of the gap retaining member and vertically penetrates the wedge- The corresponding screw portion 33 is positioned in the installation space S when the form assembly is installed and the corresponding screw portion 33 is placed after concrete pouring and curing, Only the main bolt 32 is detached from the seperate bolt 31 and is separated from the concrete wall.

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, Unlike the conventional spacing member, it is not necessary to remove the end portion of the seperate bolt 31 projecting to the outside of the wall.

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 seperatel bolt 31 as a consumable material, and the configuration of the other spacing member can be reused, and therefore, it is very excellent in usability and versatility.

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,

The tool to be used may be different depending on the characteristics of the construction site.

In the present invention, the protruding hitting portion 37 protruding in the form of a column is formed at the outer end of the nut portion 36. When the body bolt 32 is fastened and detached, the user pushes the protruding hitting portion 37 ).

The main body bolt 32 is inserted into the through hole 11A of the board member 11 and can be inserted into the through hole 11A by a side pressure or the like due to the concrete curing, 11A < / RTI > may not be collinearly located at the correct position,

By allowing the user to strike the protruding striking part 37, convenience of fastening and separating operation of the body bolt 32 can be achieved.

The nut portion 36 is not damaged or damaged even if the user hits the outer end portion of the main body bolt 32 due to the protruding striking portion 37.

4, the wedge member 38 is inserted through the slit grooves 22 of the tongue-and-groove member 20 and the slit holes 35 of the main body bolt 32, 30 are fixed to the tongue-and-groove material 20, that is, the form panel 10, so that the space of the form panel 10 is maintained as well as the lateral pressure due to the concrete pouring and curing.

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 present invention is characterized in that the wedge member 38 is struck to fix the gap holding member 30 while being fitted to the exposed portion 34 of the gauze 20 and the gap holding member 30, And the gap is maintained. As a result,

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 of the formwork panel to which the gap retaining member is fastened to the long reinforcement 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 form panel 10 of the present invention will be described as an example.

The user first joins the form panel 10 of the present invention and the general panel 1 through the fastening holes 12A and 2a of the panel frames 12 and 2 to form a large foam that is in line with the width of the wall .

The form panel 10 and the general panel 1 of the present invention can be arranged in a zigzag arrangement as well as being arranged in the same line, thereby increasing the coupling and supporting force between mutually contacting panels, .

In addition to using the form panel 10 and the general panel 1, the form panel 10 of the present invention can be used as a large form by connecting only the form panels 10 of the present invention. The form panel 10 will be utilized which removes the auxiliary protrusion 14 from the frame 12 or without the auxiliary protrusion 14.

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 member 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, when insertion of the space holding member 30 is difficult due to the problem that the positions of the corresponding supporting holes 27A or the through holes 11A do not coincide with each other, the protruding striking portions 37 of the body bolts 32, So that it can be forcedly inserted.

The gap holding member is inserted into the formwork panel in a coupled state, or the other side of the septa bolt is inserted into the panel in a state where the main bolt is coupled to one side of the inner panel and then the other main bolt is inserted into the opposite form panel, .

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.

When the insertion of the gap holding member 30 is completed, the slit grooves 22 of the joist 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 assembly of the gap holding member (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 is inserted into the slit groove 22 and the slit hole 35 while the wedge member 38 is used with the slit hole 35 in alignment with the slit hole 35. 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.
