A plywood formwork (20) comprising a reinforcement material (25) and arranged in a surplus space with the column formwork (1) disposed on both sides of the formwork (10) and the formwork (10); And a support frame 31 disposed between the second plywood 23 and the vertical panel 13 and a hinge coupled to an end of the yoke 15B for the vertical panel, to allow the pivoting operation. ) And a pin member (35) which penetrates the support bracket (31) and the vertical panel (13) and passes through the fixing bracket (33) to be orthogonal to each other. Consists of including, the coupling means 30 for connecting the bow formwork 10 and the plywood formwork (20).

First, the formwork assembly according to the present invention is for constructing a pillar and a beam connected in a horizontal direction to an upper portion of the pillar,

It is provided in a plurality of pillar formwork (1) in the vertical direction, the bor formwork 10 is installed on the upper portion of each pillar formwork (1) to construct a beam connecting each pillar.

As shown in Figures 1 to 4 the mold 10 according to the present invention is

It is configured to construct a beam connecting the pillars 1 by placing concrete as a structure for constructing a beam for connecting the pillars 1 provided on both sides.

That is, the formwork 10 according to the present invention includes a horizontal panel 11 forming a bottom surface of the formwork, and a vertical panel 13 disposed on both sides of the horizontal panel 11 to form both side wall surfaces of the formwork. Done by

The horizontal panel 11 and the vertical panel 13 are connected to each other in accordance with the length of the beam,

The horizontal panel 11 and the vertical panel 13 are provided with edges at outer edges, and when the respective panels are connected, the edges of adjacent panels are fixed to each other.

And the outer surface of the horizontal panel 11 is provided with a plurality of support members (13e) in the longitudinal direction, the support member (13e) is provided with a plurality of horizontal panel yoke (15A) side by side in parallel to each other Supporting the horizontal panels (13),

The yoke 15B for the vertical panel is also in contact with the support member in the transverse direction to the outside of the vertical panels 13 to support the vertical panels 13 connected to each other.

In particular, the yoke (15B) for the vertical panel is connected or fixed by a fixing member such as a bracket to the support member for fixing to the vertical panel (13),

Alternatively, the Sephata for reinforcing the resistance of the vertical panel 13 against the side pressure caused by the flow concrete filled in the mold 10 in the vertical panel yoke (15B) provided on both sides, to maintain the gap between the two side wall surface In addition, both ends of the space maintaining members such as the Sepha bolt is connected to the yoke for vertical panel (15B) is installed on the outside of the vertical panel (13).

In this case, each panel uses a standardized product having a certain size,

The length of the beam installed between the two pillars 1 is determined according to the distance between the two pillars 1, and the formwork 10 for constructing the beam is also manufactured to correspond to the length of the beam.

In this case, after installing each of the standardized panels according to the length of the beam, a surplus space may not be generated between the column formwork 1 and the formwork 10, the standardized panels can not be installed,

In such a case, the plywood or wood is manufactured to correspond to the surplus space at the site, thereby installing the plywood formwork 20 to be manufactured on-site between the pillar formwork 1 and the formwork 10.

Therefore, after pouring concrete into the formwork 10 and plywood formwork 20, when the concrete is cured, the formwork 10 and plywood formwork 20 are dismantled.

At this time, the order of dismantling work of each formwork first dismantles the plywood formwork 20, and then dismantles the formwork 10.

This is because the formwork 10 is structurally configured to support the load of the formwork 10 by supporting the support 2 in the vertical direction to the horizontal panel yoke 15A.

After disassembling the plywood formwork 20, in which such a support 2 is not installed, the support 2 is dismantled, and the bow formwork 10 is then dismantled.

However, the dismantling work of the plywood formwork 20 is constructed between the column formwork 1 and the formwork 10 so that the pressure in the transverse direction acted by the formwork 1 and the formwork 10 is limited, There is a problem that the dismantling work is difficult.

Therefore, in the present invention, by connecting the bobbin formwork 10 and plywood formwork 20, and introducing a coupling means 30 for easy and easy dismantling of the plywood formwork 20 to solve the problems as described above. do.

Hereinafter, prior to describing the coupling means 30, a description will first be made of the plywood formwork 20 connected to the boring die 10 by the coupling means 30,

Next, the coupling means 30 will be described in more detail.

First, as shown in FIGS. 1 to 4, the plywood formwork 20 according to the present invention is

The first and second plywoods 21 and 23 corresponding to the horizontal panel 11 and the vertical panel 13 of the formwork 10 and the outer surfaces of the plywoods 21 and 23 in the transverse direction. And a reinforcement 25 connected in the longitudinal direction.

That is, the plywood formwork 20 is made of plywood to correspond to the surplus space to form a bottom surface of the formwork by placing the first plywood 21 in the horizontal direction, the vertical direction on both sides of the first plywood 21 By placing the second plywood 23 connected to form a side wall of the formwork.

In addition, it is supported by connecting the reinforcement 25 in the transverse direction and the longitudinal direction to each of the plywood 21, 23,

In this case, the reinforcing material provided in the second plywood 23 is padded on the upper and lower portions of the second plywood 23 to be disposed side by side in the horizontal direction, and the right side of the second plywood 23. It consists of a longitudinal reinforcement 25B which is padded and connected in the form orthogonal to the transverse reinforcement 25A.

In addition, the first plywood 21 is disposed between the pillar formwork 1 and the horizontal panel 11 by being installed on an extended portion of the horizontal panel yoke 15A,

The second plywood 23 is disposed between the pillar formwork 1 and the vertical panel 13 by connecting the longitudinal reinforcement 25B to the support member 3 provided at the corner of the pillar 1. .

1 to 5, the coupling means 30 according to the present invention is

It is configured to connect the formwork 10 and the plywood formwork 20 installed in the surplus space to integrate each formwork.

Coupling means 30 according to the present invention is pivotally hinged to the end of the support frame 31 and the vertical panel yoke 15B disposed between the second plywood 23 and the vertical panel 13 A fixed bracket 33 which is operable and supports the support frame 31;

And a pin member 35 penetrating the support frame 31 and the vertical panel 13 and penetrating the fixing bracket 33 to be orthogonal to each other.

First, the support frame 31 has a cross-sectional shape of a 'c' shape, is connected to the body 31A having a receiving portion 31C therein, and longitudinally connected to the side surface of the body 31A. It consists of a pair of 1st contact support part 31B which protruded toward the panel 13 side.

And the body 31A of the support frame 31 is vertically disposed between the second plywood 23 and the vertical panel 13,

At this time, one side surface of the body 31A, that is, the side surface formed in the direction opposite to the vertical panel 13 is in contact with the cross section of the horizontal reinforcement member 25A installed on the upper and lower portions of the second plywood 23. .

In this case, the second plywood 23 is configured to protrude toward the vertical panel 13 rather than the transverse reinforcement 25A,

The body 31A is configured to support the protrusion 23a of the second plywood 23 laterally.

In addition, the core (40) is inserted into the receiving portion (31C) of the body (31A), the neck 40 is configured to contact the protrusion (23a) of the second plywood (23),

The neck 40 is in the direction of facing each other, namely transverse because the body 31A having a 'C' shape is in contact with the lateral reinforcement 25A and the edge portion 13a of the vertical panel 13. When pressure acts in the direction, stress may be concentrated in the body 31A and deformation may occur. Therefore, the support frame 31 is inserted into the accommodating part 31C and resists the lateral pressure acting on the body 31A. Stiffness).

In addition, after the concrete formwork 10 and plywood formwork 20 is installed, when the concrete is placed in this inner space because the concrete has a high fluidity, when the concrete is poured, the second plywood 23 and the vertical panel 13 Side pressure is applied.

At this time, since the protrusion 23a of the second plywood 23 is not supported by the lateral reinforcing member 25A, the second core plywood 23 is a weak part by resisting the lateral pressure caused by concrete. By supporting the protrusion 23a of the reinforcement of the rigidity of the second plywood 23.

In addition, the first contact support part 31B is connected to the other side of the body 31A, that is, the inner side and the outer side of the side part arranged toward the vertical panel 13, and protrudes toward the vertical panel 13,

In particular, the first contact support part 31B provided on the inner side is configured to protrude in the inward direction of the formwork by the thickness of the second plywood 23.

This is because the second plywood 23 is not in contact with the vertical panel 13 to form a space (S) spaced apart at a predetermined interval,

The side surface of the first contact support part 31B disposed in the inward direction is arranged in the separation space S.

Therefore, the side of the first contact support 31B is in contact with the concrete surface placed inside the formwork to form the inner surface of the formwork,

At this time, the side of the first contact support portion 31B is formed on the same plane as the inner surface of the second plywood 23 and the vertical panel 13 so that the concrete surface can be formed evenly,

The connection between the second plywood 23 and the vertical panel 13 resists the side pressure caused by the flowable concrete placed in the formwork to reinforce the rigidity at the connection.

In particular, when the dismantling work of each formwork, the first contact support portion (31B), when the support frame 31 is dismantled, the separation space (S) is formed between the formwork (10) and the plywood formwork (20) According to the dismantling order of the formwork as described above, when the dismantling work of the plywood formwork 20 is performed first, the dismantling work of the plywood formwork 20 can be easily performed, thereby reducing the convenience and work time of the dismantling work. Through this, work efficiency can be improved.

In addition, a second through hole 31a is formed in the body 31A, and a third through hole 13c is disposed at a position corresponding to the second through hole 31a in the edge portion 13a of the vertical panel 13. ) Is provided.

Next, as shown in FIGS. 4 to 5, the fixing bracket 33 is connected to the front plate 33A through which the first pin member 36 is coupled, and the upper and lower portions of the front plate 33A. A pair of support plates 33B which are in contact with the support frame 31,

And a connecting plate 33C connected to a part or all of the supporting plate 33B, protruding to one or both sides of the supporting plate 33B, and hinged to an end of the yoke 15B for the vertical panel. It is done.

That is, the front plate 33A of the fixing bracket 33 forms the outer surface of the fixing bracket 33, and a first through hole 33a through which the first pin member 36 penetrates is formed at the center thereof. ,

The support plate 33B is connected to the upper and lower sides of the front plate 33A in a horizontal direction so that the inner side part supports the frame 10 when the bobbin die 10 and the plywood die 20 are connected by the coupling means 30. 31 is pressed against the outer surface of the support.

In addition, the connecting plate 33C extends from both sides of each of the supporting plates 33B as shown in FIGS. 6 and 7 and is arranged at the top and the bottom thereof.

As shown in Figure 6 or protrude in both directions of the support plate 33B,

Alternatively, as shown in FIG. 7, it is possible to be formed to protrude in one direction of the support plate 33B.

In addition, as shown in Figure 5 to Figure 7 between the connecting plate 33C end of the vertical panel yoke (15B) is inserted and hinged,

Each connecting plate 33C is provided with a first pinhole 33b, and the vertical panel yoke 15B is provided with a second pinhole 15a so as to correspond to the first pinhole 33b.

The pivot pin 34 is coupled to the first and second pin holes 33b and 15a to allow the fixing bracket 33 to pivot in the horizontal direction with the pivot pin 34 as the central axis. do.

This is the case that the bobbin formwork 10 and plywood formwork 20 are connected by the coupling means 30 according to the present invention.

Yoke for vertical panels directly to support the support frame installed between the vertical panel of the formwork and the second plywood of the plywood formwork,

Alternatively, there is a method of supporting a support frame by introducing a separate bracket and mounting it on the yoke for the vertical panel.

First, the direct support method by the vertical panel yoke is configured so that the end portion of the vertical panel yoke is in contact with the outer surface of the support frame, when the formwork is installed, the support frame is first installed between the formwork and plywood formwork. After that, install the yoke for the vertical panel,

On the contrary, when dismantling the formwork, the yoke for the vertical panel is first dismantled, and then the support frame is separated between the formwork and plywood formwork.

Next, when a separate bracket is used, for example, when using the 'c' shaped bracket, the bracket supports the support frame while being fitted at the end of the yoke for the vertical panel, and the yoke for the vertical panel for stable support of the bracket. The end of is extended to abut the outer surface of the support frame is disposed.

Therefore, when installing the formwork, after installing the support frame, yoke for the vertical panel should be installed,

On the contrary, even when dismantling the formwork, the yoke for the vertical panel is first dismantled, and then the support frame is separated between the formwork and plywood formwork.

In other words, the support method as described above is inconvenient to dismantle the yoke for the vertical panel in order to dismantle the support frame, especially during the dismantling work of the formwork, thereby reducing the work efficiency.

In the present invention, the fixing bracket 33 is hinged to the yoke 15B for the vertical panel, and the support plate 33B abuts on the support frame 31 so as to be supported by the yoke 15B for the vertical panel. Since the support of the support frame 31 becomes unnecessary, the yoke 15B for the vertical panel does not need to extend to the support frame 31.

Therefore, during the construction of the formwork, after turning the fixing bracket 33 to the outside direction at the end of the vertical panel yoke (15B), the support frame 31 between the formwork 10 and plywood formwork 20 Place it,

The fixing bracket 33 is pivoted inward to fasten the first pin member 36 to support the support frame 31 by the support plate 33B of the fixing bracket 33.

On the contrary, when dismantling the formwork, after removing the first pin member 36, the fixing bracket 33 is rotated outward and then removed, and the support frame is formed between the formwork 10 and the plywood formwork 20. (31) can be removed immediately.

Therefore, when dismantling the formwork, it is not necessary to dismantle the vertical panel yoke (15B) to dismantle the support frame 31, without disturbing the vertical panel yoke (15B) in the state that the vertical panel yoke (15B) is fixed By being able to dismantle the support frame 31, not only the dismantling work is easy and easy, but also the work efficiency can be improved.

In addition, the connecting plate 33C is formed by cutting the inner edge portion in a round shape to form a rounding portion 33c so as to prevent the inner edge portion from being disturbed by other structures during the pivoting operation. It is desirable to make the turning operation smooth.

Meanwhile, the plywood die 20 may be installed at one end or both ends of the beam according to the beam being constructed. In this case, the fixing bracket 33 may also be installed at one end or both ends of the vertical panel yoke 15B.

In this case, as shown in FIGS. 6 and 7, the connecting plate 33C may be formed on one side or both sides of the support plate 33B.

First, as shown in FIG. 6, when the connecting plate 33C is formed in both directions of the support plate 33B, the connecting plate 33C is installed at both ends of one vertical panel yoke 15B regardless of the rounding part 33c. Since the fixing bracket 33 can be produced in one form.

Next, as shown in FIG. 7, when the connecting plate 33C is formed in one side of the support plate 33B, the connecting plate 33C is installed only at one end portion of one vertical panel yoke 15B by the rounding part 33c. Since the fixing bracket 33 is made in two forms corresponding to each end of the yoke (15B) for the vertical panel.

Therefore, in the case where the connecting plate 33C is arranged in one direction, when the fixing bracket 33 is installed on the yoke 15B for the vertical panel, the fixing bracket 33 has a directionality,

When the connecting plate 33C is arranged in both directions, the fixing bracket 33 can be installed on the yoke 15B for the vertical panel without directivity, thereby improving workability.

In particular, it is possible to manufacture the fixed bracket 33 in one form, which has the advantage of increasing productivity and economics.

Furthermore, the pin member 35 of the coupling means 30 includes a first pin member 36 having a coupling hole 36a and a second pin member 37 having a fastening hole 37a.

The first pin member 36 and the second pin member 37 are coupled in a form perpendicular to each other.

In this case, the side edge portion 13a of the vertical panel 13 is provided with a pair of second contact supporting portions 13b protruding toward the support frame 31 to correspond to the first contact supporting portions 31B. End face of each contact support portion abuts,

On the contact portions of the first and second contact supporting portions 31B and 13b, the first and second inserting portions 31b and 13d having half grooves are joined to each contact supporting portion to form a hole-shaped insertion portion.

The insertion portions 31b and 13d are arranged at positions corresponding to the first through holes 33a of the fixing bracket 33.

Here, the installation and construction of the coupling means in the state of installing the formwork and plywood formwork

First, the fixing bracket 33 is pivoted inward with respect to the pivot shaft pin 34 so that the supporting plate 33B of the fixing bracket 33 abuts against the outer surface of the support frame 31.

When the first pin member 36 is penetrated through the first through hole 33a and the insertion portions 31b and 13d of the fixing bracket 33 in the outward direction, the first pin member 36 The coupling hole 36a is positioned on the space formed by the contact supporting parts.

In this state, when the second pin member 37 passes through the second through hole 31a of the support frame 31 and the third through hole 13c of the vertical panel 13,

The second pin member 37 is to pass through the space between the contact support,

In this case, the second pin member 37 is inserted through the coupling hole 36a of the first pin member 36 so that the first pin member 36 and the second pin member 37 are perpendicular to each other. Combined in form.

After the nut 36c is fastened to the screw portion 36b formed on the first pin member 36 to fix the first pin member 36,

The wedge pin 38 is fastened to the fastening hole 37a of the second pin member 37 exposed to the outside of the edge portion 13a of the vertical panel 13 to fix the second pin member 37. The installation work of the means is terminated.

In this case, however, the fixing operation of the first pin member 36 and the second pin member 37 may be performed by first fixing the second pin member 37 and then fixing the first pin member 36. It is also possible to carry out simultaneously.

Accordingly, the support frame 31 and the vertical panel 13 are integrally connected to each other by the pin members 36 and 37 so that the boring die 10 and the plywood formwork by the coupling means 30 are integrated. 20) are interconnected to form a form assembly for the construction of the beam.

On the contrary, when dismantling the formwork, the dismantling operation of the coupling means 30

First, the insertion part 31b (13d) and the first through hole in a state in which the nut 36c is completely removed from the threaded portion 36b of the first pin member 36 and separated from the first pin member 36. The first pin member 36 is separated and discharged from 33a.

Next, the wedge pin 38 is removed from the fastening hole 37a of the second pin member 37, and the third through hole 13c of the vertical panel 13 and the first pin member 36 are removed. The second pin member 37 is discharged from the coupling hole 36a and the second through hole 31a of the support frame 31.

In this state, when the fixed bracket 33 is pivoted outward by pivoting the pivot shaft 34 toward the central axis, the support frame 31 is formed even when the yoke 15B for the vertical panel is not dismantled. It becomes possible to separate between 10 and plywood formwork 20.

In this case, as the support frame 31 is separated, the first contact support part 31B, which is disposed inside and is in contact with the concrete surface, is separated from the concrete surface and is separated between the second plywood 23 and the vertical panel 13. The separation space S is formed.

The separation space (S) formed as described above secures a work space for input of a tool or device for dismantling the formwork, thereby facilitating the separation of the plywood attached to the concrete surface, thereby dismantling the plywood formwork 20. By facilitating the dismantling of the entire formwork, it is possible to improve the work efficiency by shortening the work time.

As described above, the coupling means 30 according to the present invention is integrated with the bobbin formwork 10 and the plywood formwork 20 to be integrated with each other.

On the contrary, when dismantling the formwork, the disassembly of the plywood formwork 20 is facilitated by the first contact support part 31B of the support frame 31, thereby improving the construction performance of the form assembly.

Furthermore, although not shown in the accompanying drawings, the insertion portion of each contact support portion through which the first pin member penetrates may be formed only in the first contact support portion or only in the second contact support portion, as necessary.

In this case, the insertion part is manufactured in the form of a hole so that the first pin member can be penetrated and coupled thereto.

In addition, when the neck is provided in the receiving portion of the support frame, the neck is provided with a fifth through hole (not shown) to correspond to the second through hole and the third through hole, or the second pin member is Pierced or pierced,

Alternatively, the neck may be cut and inserted into the accommodating part to be arranged above and below the second pin member.

The work order according to the construction and dismantling work as described above is only one example among various implementation methods and can be modified and changed in various ways according to the working conditions or the situation of the site.

In the above description with reference to the accompanying drawings, the present invention is easy to dismantle the die assembly easy to describe a specific shape and direction, the present invention can be variously modified and changed by those skilled in the art, such modifications and changes It should be construed as being included in the scope of the invention.
