BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated large formwork completed by connecting a plurality of formwork panels in parallel, and more particularly to a prefabricated large formwork having a plurality of formwork panels of the same shape, A large prefabricated large formwork is used to easily install the girders and strips, and this is used as a vertical formwork. In order to integrate the floor slabs and the vertical members, a prefabricated large formwork for the construction of the vertical members is lifted by the thickness of the floor slab To a floating installation structure of the form so as to maintain the state.

Conventionally, a prefabricated form (euroform, aluminum foam, etc.) has a structure in which the form panels are connected to each other by using a binding pin and a space-maintaining plate-form tie (flat tie). There is a problem that the binding pin can be detached due to the vibration of the electric compaction bar and a gap easily occurs between the form panels. In addition, since the flat tie is inserted into the machining gap of the binding rib that connects and assembles the form panel and the form panel, the flat tie protrudes out of the form panel. Therefore, in the assembled large form state, , Which is considerably uneconomical in terms of labor force requirements.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 illustrate a large-sized prefabricated formwork according to the present invention. The large-sized prefabricated formwork 100 of the present invention comprises a plurality of formwork panels 110 and a plurality of fasteners 110, (120, 130). 1 and 2 are classified according to the shape of the fastener.

The form panel 110 is a unit panel constituting the large formwork 100. The form panel 110 has a plate shape in which one surface is smooth and extends vertically from one end of the form plate 111 toward the other surface of the form plate, A coupling rib 112 formed on one side of the coupling rib 112 and having a coupling protrusion 112a formed on an outer surface thereof and a coupling protrusion 112b formed on an inner surface of the coupling ring 112, And a coupling groove 113a corresponding to the coupling protrusion 112a of the one coupling rib 112a is formed on the outer surface of the other end portion and extends vertically toward the surface of the other end of the form board 111, And a binding rib on the other side on which the rib 113b is formed.

The fasteners 120 and 130 are arranged such that the binding ribs 112 on one side of the form panel and the binding ribs 113 on the other side of the formwork panel are engaged with each other and are guided by the two tabs 112b and 113b, Shaped coupling ribs 112b and 113b of the T-shaped coupling ribs, when the plurality of formwork panels are arranged and connected to each other to fix the plurality of form panels 110 to each other, do.

With such a fastener configuration, the binding by the binding ribs 112 and 113 between the form panels 110 does not necessarily have to be precisely performed. Further, the fastening ribs 112 and 113 are combined with the binding ribs 112a formed in the binding ribs 112 and 113 The grooves 113a are preferably formed in a trapezoidal shape rather than being formed in the shape of a reverse trapezoid (dovetail). That is, when the form panels are manufactured in an inverted trapezoidal shape for connection between the form panels 110, the form panels should be coupled to each other by the sliding method in the upper and lower positions. However, in the case of the trapezoidal form, This is because the obtuse angle (obtuse angle) treatment of the coupling projections 112a and the coupling grooves 113a formed in the coupling ribs 112 and 113 facilitates management as a structure with few damages.

The present invention proposes a horizontal support large fastener 130 as shown in FIG. 1 and a connection type fastener 120 as shown in FIG. 2 as a fastener. The horizontal support large fastener 130 has a structure in which a horizontal support large fastener supports a form panel And it is proposed in consideration of the connection with the welt 140 when the welt 140 is installed to support the form panel. Of course, as shown in FIG. 2, the horizontal support large fastener 130 and the connection fastener 120 may be used together.

The horizontal support large fastener 130 has a T-shaped groove 131. When a plurality of the formwork panels 110 are arranged and connected together while forming a T-shaped binding rib, the T-shaped binding ribs are coupled to the T- And is reinforced and supported while connecting the form panels 110 to each other.

As shown in FIG. 1, the horizontal support large-sized fasteners play a role of joining because they support the formwork part 111 in the width direction while connecting the wall formwork panels as shown in FIG. 1, and considering the role of the joining, It is preferable that the horizontal support large-size fasteners 130 have a narrow installation space at the bottom and a wide installation space at the top.

The connecting fastener 120 includes a first connecting piece 121 which is divided into a body 121a and a latching ring 121b and is configured to enclose a latching protrusion 112b of the T-shaped binding rib by a latching ring 121b; A second connecting piece 122 which is divided into a body 122a and a latching ring 122b so as to surround the other latching jaw 113b of the T-shaped binding rib by the latching ring 122b; And a fastener 123 for fastening the first connecting piece and the second connecting piece to the T-shaped binding ribs tightly by connecting the bodies 121a and 122a of the first connecting piece 121 and the second connecting piece 122 .

As shown in FIG. 2, the fastener 120 of the connection type is preferable for tight binding between the form panels 100 by allowing the first connecting piece 121 and the second connecting piece 122 to completely engage the T-shaped binding ribs. In FIG. 2, a bolt is used as the fastener 123. In order to fasten the bolt, a female screw acid should be formed on the bodies 121a and 122a of the first connecting piece and the second connecting piece.

2, a horizontal wale 140 is installed to support the interconnected form panels 110. The wale 140 is fixedly installed according to the arrangement relationship with the connection type passer.

First, a wristband is fixedly installed on the front surface of the first connecting piece 121 of the fastener 120 and the front surface of the second connecting piece 122, A method in which the connection fastener 120 is inserted into the wrist strap 140 and then the wrist strap 140 is fixedly attached to the front surfaces of the latching jaws 112b and 113b of the T-shaped binding ribs of the form panel A wedge insertion type connection type fastener using method).

The first method of using a tie closure type fastener of the present invention is such that the tie closure type fastener 120 is in contact with the tie strap 140 and does not fix the tie strap 140, Means should be prepared.

FIG. 2 shows an example using a wedge insertion type fastener (described later) having a binding portion extending from a foam tie or a self-fixing means as a separate fixing means for fixing the wale band 140. FIG.

The application of the first method employs a tie closure fastener 120 having a length greater than the dancing of the wale 140 so that the concrete support force of the form panel 110 passes through the fastener 120 to the wale 140 in a stable manner To be transmitted.

Unlike the first method described above, unlike the first method, the wedge insertion type fastener 120 is provided with a fixing means to fix the wale 140 in the second method.

In order to apply the second method, a wedge 140 is formed on one side and a closed side is a closed П-shaped cross-sectional member, and a binding hole 141 is formed on the closed side. The wedge- It is necessary that the bodies 121a and 122a of the first connecting member 121 and the second connecting member 122 have a length shorter than the opening width of the opening of the wale 140. The wrist strap 140 is fixedly installed by inserting the wrist strap insertion type fastener 120 into the wrist strap through the open face of the wrist strap 140 and by fastening bolts 142 And then fastening it to the front surface of the body 121a or 122a of the first connecting piece or the second connecting piece by inserting it into the binding hole 141 of the band. As a result, the fastening bolt 142 is caught in the closed surface binding hole 141 of the wristband 140, and the open side of the wristband 140 is brought into close contact with the entire surface of the fastening tabs 112b, 113b of the T- , And as a result, the wale band (140) is tightly bound and fixed to a plurality of mutually connected form panels.

FIG. 4 is a view showing a floating installation structure of a form using the above-described large-size prefabricated building 100. The floating construction of the formwork of the present invention is a vertical structure for a floor slab and a vertical member (wall, column) The formwork 200 is used to support the vertical face form and maintain the vertical face form of the floor slab in a floating state.

That is, the floating installation structure of the formwork of the present invention comprises: a vertical member of a lower layer constructed in a reinforced concrete structure so that a protruding reinforcing bar (R) protrudes upward; A dowel 200 fixedly installed on the upper surface of the lower portion of the vertical member by the thickness of the upper floor slab to be installed; And a vertical surface formwork installed for the upper part vertical member on the lower part vertical member and supported by the formwork support part 200 to be maintained in a floating state. Of course, the above-described large-size prefabricated formwork 100 can be used as a vertical face formwork. FIG. 4 is an example of using a prefabricated large formwork as a vertical formwork.

At this time, the formwork region 200 can be fixedly installed by having a binding portion 210 bound to the protruding reinforcing bars R of the lower layer vertical member, and can be connected to the binding portion 210, The large-sized formwork 100 is supported by the mounting portion 220 + 230 protruding outside the vertical member and on which the large-size prefabricated formwork 100 is mounted, so that the floatable state can be maintained. Of course, in order to maintain the floating condition of the prefabricated large formwork using the formwork 200, the prefabricated large formwork 100 is in a state in which the frame is assembled to the form of the vertical member (in the case where the vertical member is a column, If it is a wall, it has a frame of a wall formwork).

The concrete formwork 200 will be embedded in the vertical members and floor slabs of the upper layer in the future when the concrete is poured. In order to secure a sufficient supporting force when the large formwork of the formwork 200 is assembled, it is preferable to make it with iron.

4 (c) shows a formwork 200 having a detachable coupling structure 220 + 230. The detachable coupling structure is a part disposed inside the vertical member of the upper layer to be installed And a support bolt 230 protruding from the vertical member of the upper layer to be fastened to the female thread of the sleeve 220. The sleeve 220 has a female thread formed at both ends thereof, As shown in FIGS. 4A and 4B, the mounting portion 220 + 230 having such a detachment / coupling structure is used to mount a large-sized prefabricated mold used in the vertical member construction of the lower- It is advantageous to set the installation position in advance before the rise.

In other words, before lifting the prefabricated large formwork 100, only the portion of the sleeve 220 is preliminarily aligned with the height (up to the thickness of the upper floor slab to be installed on the upper part of the vertical member of the lower layer) And then the support bolt 230 is fastened to the sleeve 220 after the large-sized assembly 100 is lifted up and the assembly-type large workpiece 100 is mounted on the support bolt 230.

The die unit 200 further includes a support unit 240 that directly supports the sleeve 220 of the mount portion on the upper surface of the vertical member of the lower layer that is coupled under the sleeve 220 of the mount portion . Since the height of the receiving unit 240 is determined according to the thickness of the upper floor slab, the height of the receiving unit 240 can be adjusted so as to flexibly correspond to the thickness of the upper floor slab and the construction error of the lower vertical member. . When such a configuration of the receiving portion 240 is included, the binding portion 210 does not need to be bound tightly to the reinforcing bar, and therefore, the binding portion 210 can be a simple ring type as shown in Fig. 4 (c).

On the other hand, when the prefabricated large formwork used for constructing the vertical part of the lower part is directly elevated for use in the vertical member construction of the upper part, the elevation support 300 as shown in FIG. 2 is used to use the prefabricated large formwork . 2, a hole is formed in the rib of the formwork panel constituting the assembled large-size mold 100, and the elevation support 300 is inserted into the hole of the elevation support 300, . The lifting post 300 is fixed to the bottom of the lower portion and serves to guide the lifting path of the prefabricated large formwork 100 and to support the lifted condition temporarily and stably.

The elevating pillar 300 fixed to the bottom of the lower part floor is constructed such that the formwork for the construction of the upper floor slab is completed and the reinforcement is completed after the prefabricated large formwork 100 is held by the formwork 200, It is preferable to push it up to the upper layer portion. This is to keep the floating state of the prefabricated large formwork stable for a long time. When the concrete of the floor slab is cured in the future, the elevation support pile 300 is elevated higher than the lower end of the prefabricated large formwork 100 so that it is not buried in the concrete of the floor slab under construction. And to be fixed to the finished floor slab for repetitive work of lifting.

According to the present invention as described above, a plurality of form panels of the same shape can be easily enlarged to a required width without being welded, and as a result, it is expected that the formwork installation and disassembly process will be facilitated.

Further, by using fasteners for fixing the connecting state of the mold panels interconnected with each other, the number of components constituting the large molds can be reduced, and the number of components forming the large molds can be reduced, It is anticipated that the long formwork of the panel, the joist line,

Further, by using the formwork region bound to the protruding reinforcing bars of the completed lower-layer vertical member, the vertical face form of the vertical member can be lifted stably as much as the thickness of the bottom slab, so that the integrated construction of the floor slab and the vertical member becomes possible.
