Description

The structure of concrete forms constructed for wall and slab}

The present invention relates to the structure of the formwork for the construction of concrete walls and slabs of a multi-storey building, and more specifically, to a plurality of places where the left and right edges and two corners of the two inner wall formwork for the wall facing each other evenly divided. It is possible to adjust the height of the upper part and rotate the uprights.The deck supports, which act as pillars, are installed upright together with the formwork panels. Multiple decks on the upper surface of multiple deck support bars parallel to each other at the same time parallel to the ground after detachably joining both ends of the deck support bar acting as a beam, consisting of a bent link-linked H-beam By constructing the deck by detachably connecting the panels, there are many supports that must be installed upright on the floor to support the deck for the slab. When dismantling, the deck support bar is bent at the time of dismantling, thereby lowering the height of the middle part so that the deck can be easily dismantled, and at the same time, it does not use wood, thereby improving the recyclability of the formwork structures. It is about the structure.

The multi-layered structure of concrete reinforcing structure begins with the installation of concrete wall and slab construction formwork. First, the interior space is made into a mold like a wall shape, and the ceiling slab construction board is placed on the ground. After horizontal installation, the concrete is formed by filling and curing the inside of the frame and the upper surface of the plate, and the 'frame' and the 'plate', called 'forms' are generally rectangular panels called formwork panels. It is made by connecting a number.

Therefore, the construction of the wall and the slab starts by installing the formwork, which is a mold having an interior space and an upper surface to connect the plurality of formwork panels to fill concrete.

Prior to describing the present invention and the prior art, terms for the formwork are defined as follows to avoid confusion about the terminology of the formwork.

Formwork for wall construction consists of two parts that are in close contact with each of the inner and outer two surfaces of each wall, each part can be divided into upper and lower ends, each upper and lower ends are separated into a plurality of unit panels, The unit panel is composed of 'form panel', a number of form panels are combined to the left and right, 'top formwork' to be located at the top, 'down formwork' to be located at the bottom, and a number of formwork panels constituting the top and bottom formwork. Formwork panels are coupled by various coupling members so that the front surfaces are located on the same plane and are in close contact with one side of the wall.

Thus, one wall is made of concrete filled in the space between two inner wall formwork, each side of which is installed so as to face each other while being spaced by the thickness of the wall.

In addition, the ceiling slab formwork is coupled to the upper end of the inner wall formwork parallel to the floor so that the upper surface of the plurality of formwork panels form the same plane and the gap between the two opposing inner wall formwork is not blocked. Cocrete is placed together between the inner wall formwork and the upper surface of the slab formwork. The slab formwork is called 'deck' to distinguish it from the wall formwork, and the formwork panel constituting the deck is called 'deck panel'. In other words, both the interior formwork and the deck are defined as 'forms'.

It is a basic component of formwork, and as a material of the formwork or deck panel, which is composed of a plate that adheres to concrete and a frame supporting the plate, only wood has been mainly used in the past, but in the case of using a wood panel, connection assembly between panels is Since it is made by nailing or tightening of wires, a lot of manpower and time are required for the formwork installation work, and also a lot of time and manpower is required for the demolition work of the formwork after concrete curing.

In addition, the wood panel is reinforced with a rectangular wooden bar on the back of the plywood, but due to the nature of the wood it is easy to be deformed by the pressure of the concrete filled in the formwork, the larger the size of the wall, the more the tendency increases, As a result, the outer surface of the wall often fails to form a flat surface.

Therefore, in order to prevent the deformation of the wood panel as described above, there is an inconvenience of reinforcing the formwork panels with a separate reinforcement before filling the formwork with concrete, the wood panels are deformed during the installation and demolition of the formwork. There are many cases that are damaged or broken, so the number of times of repeated reuse is extremely limited, and short lifespan is also a disadvantage, as well as the treatment of damaged and damaged wood panels.

In order to solve the above problems of the wood panel, the board is made of wood, but the wood-metal panel using the frame as metal such as steel or aluminum alloy (hereinafter referred to as 'aluminum') has been developed and used in various construction sites. In addition, the range and scale of its use are rapidly increasing.

However, in the case of the steel frame panel, since the weight is considerable, it is difficult to handle because it is difficult to handle, and the workability is low, and since rust is easily generated and durability deterioration due to rust is large.

The aluminum frame panel was developed to solve the shortcomings of the steel frame panel, which is very light in weight compared to the steel frame panel, and because of its high rigidity, there is no deformation due to the pressure of the concrete, so the quality of the cured wall is excellent. In addition, it is highly appreciated that the service life is semi-permanent because it is easy to install and dismantle and can be reused repeatedly.

In order to assemble the various panels as described above to form a form of a form in which the concrete is poured, so that the initial installation shape of the formwork is not deformed by the weight of the concrete to give a significant pressure to each panel until curing after pouring. In other words, various supports should be installed on the back of each panel to withstand the weight of concrete. Especially, because the slab deck is supported by the upper end of the inner wall formwork only at both ends, a considerable number of supports are placed on the floor. Conventional formwork, such as to be built between the surface and the bottom of the deck panel has a number of problems, looking at on the basis of Figure 1 showing the conventional formwork as follows.

As shown, the conventional formwork is upright on the upper surface of the wooden foundation bar 12 fixed to the bottom surface (A) for the construction of each wall (W) and two inner wall formwork per wall consisting of two stages up and down ( 11) and a deck 13 is placed at the upper end of the inner wall formwork in parallel with the floor.

The conventional deck 13 is usually a wooden plywood is used, the bottom of the deck 13 made of plywood in order to support the concrete poured into the slab a plurality of parallel horizontal bars 14 (long line, long line) Are closely attached to the bottom of the horizontal bars 14, and a plurality of vertical bars 15 (yokes) orthogonal to and parallel to them are closely attached to each other, and then a plurality of supports S3 are formed along the bottom of each vertical bars 15. Upright to the bottom surface (A) is a structure to support the deck 13, along the upper end of the inner wall formwork, the wood (T) parallel to the horizontal bar 14 is coupled to the deck 13 and the inner wall formwork ( 11).

At this time, the two inner wall formwork 11 facing each other in a state in which the flat front face is spaced apart by the thickness of the wall (W) is coupled to a plurality of connecting pieces (C) to cross the wall in the thickness direction, and after completion of the wall construction each connecting piece Both ends of (C) are cut to dismantle the inner wall formwork, and the intermediate portion of each connecting piece (C) is buried in the wall concrete.

In addition, on each rear surface of the inner wall formwork 11, a plurality of formwork panels constituting the inner wall formwork are prevented from being separated from the initial assembly position by the pressure of the load of concrete poured for the construction of the wall W. The vertical supports S1 and the horizontal supports S2 are combined.

In addition, the deck 13, which is a slab formwork, has two front walls closely contacted with two opposing surfaces of two side walls facing each other, and are spaced apart by a distance from the bottom (A) surface so that each back surface faces each other. Since both ends are placed from the front end of each front side to the back side to form the top plate of the bridge spanning the two piers, the load of the entire concrete that is cast on the top of the plywood deck to construct the slab is the upper end at both ends of the deck. The structure is supported only by the two inner wall formwork combined.

Therefore, in the structure as described above, since the deck made of plywood can not withstand the load of the concrete, as described above, a number of horizontal bars 14, vertical bars 15 between the bottom and the bottom surface (A) of the deck (13) And supports S3 are installed.

Therefore, the conventional formwork installed as described above has various problems as follows.

First, since the base bar installed at each lower end of the inner wall formwork is usually stacked with a plurality of timbers, it is difficult to level the sides and the height of the form panels closely, so it is easy to match the horizontality and verticality between the formwork panels. It does not reduce workability of formwork installation.

Second, since only the end of the deck made of plywood is supported by the inner wall formwork, a large load is placed on the inner wall formwork, and the shape of the inner wall formwork tends to be distorted, and in order to prevent this, a large number of vertical supports and horizontal supports are formed in the inner wall formwork. Should be bonded to the back of the bar, the formwork installation time is long, the construction period is extended.

Third, an excessive amount of supporting means such as horizontal bars, vertical bars, lumber, and a support is necessary to support an intermediate portion other than both ends of the deck supported by the inner wall formwork, and the time required for installing and dismantling the supporting means will be longer. In addition, since the operation of shiram is limited by a number of dense supports standing upright on the floor, it is necessary to inspect the casting condition of walls and slabs on the back and bottom of the inner wall formwork and deck, or to perform additional floor construction. Is difficult.

Fourth, various subsidiary materials for installing the formwork, namely deck, horizontal support, vertical support, horizontal bar, vertical bar, support, foundation bar, etc. are mainly used plywood, wood or pipe, each wood is nail, etc. When combined with the formwork, since the damage rate of the various subsidiary materials during the installation and dismantling of the form is high and the recycling rate is low, the initial form cost is low, but as a result, the construction cost increases, and the cost for processing waste materials is generated.

The present invention was devised to solve all the problems of the conventional formwork as described above, using the deck support and deck support bar taking the form of pillars and beams of the building, the deck and slab concrete installed on the deck support bar By allowing the deck support to handle the load of the deck support, while avoiding the need for a number of various support means for the deck while minimizing the load applied to the inner wall formwork, while adjusting the height of the upper end of the deck support and the deck support bar to be bent structure By lowering the height of the deck support bar when dismantling the deck, it is not only easy to dismantle the deck installed on the upper surface of the deck, but also eliminates the use of wood, thereby minimizing the time and labor for installing and dismantling the formwork and using it for the formwork. Initial investment costs by improving the recyclability of various materials In spite of the increase, as a result, there is an object of the present invention to provide a structure of formwork that can reduce the construction cost.

The above object of the present invention is achieved by a base buckle with a height adjustable in a turnbuckle, and a bar-type deck support and a bendable support bar that are capable of moving up and down and rotated.

The structure of the wall and slab construction form of the present invention is applied to the structure of the pillar and the beams placed on the two pillars, and the two components that perform the role of the pillars and beams are placed on the deck and the upper surface of the deck. In addition to supporting, the technical features of the installation and disassembly have a simple structure.

The formwork structure of the present invention is largely composed of the wall formwork for wall construction, slab construction deck, foundation bar, deck support and deck support bar, the upper part of the deck support serving as the pillar is movable up and down and rotatable At the same time as the double structure, the deck support bar serving as the beam has a structural feature that has a bendable structure.

The foundation bar, which is installed on the bottom surface along the lower end of the wall and whose height is adjustable in a turnbuckle type, is composed of a pair of partial cross sections having a bar shape having a "a" and "b" shape cross sections, respectively. The two chords are fluidly coupled to have a cross-section, and the height adjusting mechanism for screwing the height of the two chords between the inner bottom and the ceiling is coupled to each other so that the internal wall formwork placed on the top of the base chock You can adjust the height.

In addition, the deck support, each of the two inner wall formwork facing each other in a space such that the back of the deck support forms a coplanar with the front of the inner wall formwork between the long formwork panels constituting the inner wall formwork in close contact with the wall surface. Each of the deck support is installed so as to stand upright on the floor facing each other, each deck support is composed of a fixed support and a flow support is installed when the flow support was raised by rotating the flow support in a downward and forward downward direction when dismantling the formwork It is possible to reduce the height of the deck support of the city, by doing so it is possible to bend the deck support bar coupled to the bottom surface of the both ends to the upper surface of the flow support of the top of the deck support to lower the middle height between the two ends.

At this time, as shown in Figure 2, the upper and lower length (L ₁ ) of the general formwork panel 20 consisting of a plate (PL) whose front surface is in close contact with the wall surface and the frame (F) for reinforcing the plate (PL). ) Corresponds to approximately half of the height of the wall, and the formwork panel 20 is integrated into one of the upper and lower ends to have a length L ₂ approximately similar to the height of the wall, called 'long formwork panel 20'. The height of the foundation strip, the length of the long formwork panel 20 'and the height of the deck panel are the height of the wall.

That is, the length (or height) of the long formwork is equal to the sum of the maximum length of the deck support bar and the height of the deck support bar.

And, each deck support is placed on the upper surface of the foundation along with the inner wall formwork, because the thickness of the deck support is greater than the thickness of the foundation bar, unlike the thickness of the inner wall formwork, the back of the deck support with the front of the long formwork panel Although it is in close contact with the wall surface, the front face protrudes from the rear surface of the inner wall formwork, and the bottom face of the protrusion part is in a state of floating in the air by the height of the foundation band from the bottom face.

Accordingly, in order to support the bottom of the protrusion of the deck support bar and adjust the height thereof, a support base is interposed between the bottom and the bottom of the protrusion of the deck support, and the support base consists of an upper base and a lower base. When the two pedestals are stacked, the upper surface of the upper pedestal and the lower surface of the lower pedestal are parallel to each other, but the bottom surface of the upper pedestal, which is the contact surface of the two pedestals, and the upper face of the lower pedestal form an inclined surface in the opposite direction to each other. By moving along the upper surface of the height of the protruding side of the support base, that is, the relative height with the base bar can be adjusted to control the upright of the deck support bar.

In addition, the deck support bar, which is disposed on the upper end face of each pair of deck supporters opposed to each other and is detachably coupled to each other by placing bottom surfaces of the pair of deck supporters facing each other, has a plurality of short-cut H-beams. These are combined by articulated links to form a long H-beam and bendable. The foundation bar, deck support, deck support bar, formwork panel and deck panel frame are made of metal, especially lightweight aluminum alloy extruded materials. It is preferable to use it, and it becomes possible to raise the degree of recycling of formwork.

Looking at the structure of the present invention formwork configured as described above is as follows.

In a multi-storey building, formwork is installed on each floor, and a plurality of inner walls or side formwork (building exterior surfaces) and a deck are connected to form a plurality of walls. In this case, the inner wall formwork is spaced by the thickness of the wall to provide a flat front surface. It is connected to each other by the inner wall formwork which is close to the wall surface of the adjacent room facing each other, that is, the connecting pieces (C), and forms a layer as such a connecting structure, but for convenience of description, it is intended for a single room. Although concrete is not poured, it will be described as having a virtual wall.

The inner wall formwork is installed in the shape of a flat quadrangle to form four wall surfaces, and three pairs of decks facing each other at the left and right sides of the two inner wall formwork, each of which is opposite to the rear side of the four inner wall formwork, and the center and the center.

Then, the bottom surfaces of the long formwork panels are placed on the top surface of the foundation platform so that all the front surfaces of the plurality of long formwork panels closely adhere to the wall surface and form the same plane along the wall surface. After connecting the bottom of the separator and the long formwork panel, between the left and right adjacent long formwork panel, and the long formwork panel and the deck support with pins, each deck support bar is placed on the top of each of the two pairs of opposing deck supports. The top surface of the deck support and the bottom of each end of the deck support bar are detachably coupled.

At this time, the three deck support bars are installed at the position connecting the two upper end portions of the two opposite walls perpendicular to the wall on which the deck support is installed and the central upper end of the two walls on which the deck support is installed and are in parallel with each other. On both sides of the deck support bar installed at one upper part and the deck support bar located at the center of the upper part, and the deck support bar located at the center of the upper part and the deck support bar at the other upper part, the bottom of both ends is laid so that the rails on which the sleepers are placed are inverted. The deck is formed by closely arranging a plurality of deck panels to the top surface of the deck support bar so that the top surface is coplanar with the top surface.

When the formwork is dismantled, the deck support bar can be reduced and the deck support bar bend to lower the deck to easily dismantle the deck panels.

The details of the purpose and technical constitution according to the present invention, including the effect thereof, will be clearly understood by the following description with reference to the drawings showing preferred embodiments of the present invention.

The upper and lower guide bars (GB) (GB ') through the engaging hole (H ₃ ), through hole (H ₁ ) (H ₂ ) and through hole (H ₁ ') (H ₂ '). In the state coupled to the upper and lower sides of the two side walls of the support (24B), respectively, the engaging pieces are moved forward and backward so that the vertical portion of each locking hole (H ₃ ) is the through hole (H ₁ ) (H ₂ ) When the guide bar (GB) (GB ') is able to move along the through holes (H ₁ ) (H ₂ ) to be able to move up and down the flow support, but the position is not fixed do.

In addition, the guide bars are horizontal to the locking holes when the moving supports are moved upwardly and the locking pieces are moved so that the vertical portions of the respective locking holes H ₃ do not coincide with the through holes H ₁ and H ₂ . By catching the part, the flow support is fixed in the raised position.

In addition, the upper plate 24B1 of the flow support is detachably coupled to one side end of the bottom surface of the deck support bar 25 through the coupling hole h, and the flow support 24B is lowered in the state in which both of the flow support are lowered. When the upper guide bars GB coupled to the outer surface of the side plate 24B2 are separated, the flow support 24 is rotatable forward and downward with two lower guide bars GB 'as the rotation axis.

In addition, in order to fix the deck support 24 to the wall to be cast so as to support the load of the concrete for tech and slab, the embedded bolt B 'penetrating the rear surface RS from the front of the deck support 24. ) Is combined, and the buried bolt (B ') is embedded in the wall concrete to be poured and fixed.

As shown in FIG. 12, the deck support bar 25 cuts one long H-beam into three short pieces and then links the cut short H-beams to each other. 25B of two bones detachably coupled to the upper surface of each of the flow supports 24B of 25), and both ends of the bottom of each of the bottoms of the bottoms of the two supports 25A are connected by the articulated links LK. It consists of an intermediate portion 25B to be coupled.

Therefore, the curing of the wall and the slab large concrete is completed, and each floating support 24B on the upper side of the two deck support facing the formwork is dismantled with the deck support bar 25 to lower the deck support bar 25 and the slab side After forming a space between the upper and the guide bars (GB) of each of the flow support, each of the support supports of the deck support bar coupled to the upper surface of the lower support bar (GB ') as the axis of rotation Rotation forward and downward with the 25A, the articulated link of the bottom of the deck support bar is unfolded so that the intermediate portion 25B interposed between the two deck supports 25A maintains a parallel state with the floor, and the upper surface is lowered. It is easy to dismantle the decks installed in.

And, as shown in Fig. 13, in each portion adjacent to both ends in the longitudinal direction of the back of the deck panel (26A) used in the present invention formwork structure, the assembled rib (L5) upright on the back along the full width of the deck panel back The outer surface side deck panel of the assembling rib (L5) is in close contact with the upper surface of the deck support bar 25, the inner surface of the assembling rib (L5) on the side of the width direction end side of the upper surface of the deck support bar (25). It is caught and the installation state is stabilized.

At this time, the back of the deck panel 26A between the two parallel assembly ribs (L5) is in a state floating in the air toward the bottom surface.

Looking at the stacking structure of the formwork installed by the present invention construction method as described above, in the side of the long formwork panel in the order of the bottom-basin cross-stall panel-deck panel, on the side of the deck support floor-base scissor-deck The top of the deck support bar is located on the same plane as the top surface of the long formwork panel, and the bottom of the deck is located on the top surface of the deck support bar and the top surface of the long formwork panel. At the same time, the front side of the long formwork panel and the one end surface of the deck panel which are in close contact with the surface of the wall form the same plane. It consists of the back and the two side walls of the fixed support, which does not correspond to and is not occupied by the flow support on the rear side of the flow support back side. There is a 'c' shaped residual cross section, the top surface of which is lower than the top surface of the flow support, so that when the flow support is at its highest height, the top of the flow support from the top surface of the 'c' shaped residual cross section of the fixed support A space is formed on the side of the wall between the top surfaces of the deck support bars placed in the bar, that is, the top surface of the remaining 'c' shaped cross section of the fixed support, the back width of the deck support and the thickness of the long formwork panel ' A separate formwork panel having a length from the upper end surface of the 'c' shaped residual cross section to the top of the deck support bar should be combined. Thus, instead of the separate formwork panel, the 'c' shaped remaining cross section of the fixed support is It is also preferable to extend the height of the formwork panel of the ie, the elongated formwork panel of the 'c' shaped back surface of the rear side of the back of the flow support at the fixed support post. When extended upward to the height of the upper surface of the, the separate formwork panel is not necessary, the height of the fixed support post is the same as the height of the long formwork panel, the height of the deck support bar on the top surface of the flow support located at the highest height Will be equivalent to

In addition, the distance between the longitudinal center lines of the two parallel deck support bars is the same as the length of the deck panel, the longitudinal ends of the deck panel to coincide with the respective longitudinal center lines of the upper surface of the two deck support bars.

Therefore, a gap between the longitudinal end face of the deck panel placed up to the center line of the upper surface of the two deck support bars provided at the left and right side edges of the wall and the back surface of the long formwork panel which is in close contact with the side surfaces of the two deck support bars (R). ) Is formed, and the side panel 26Aa, which is a narrow deck panel, is coupled to the gap.

In addition, the deck support side side panel (26Aaa), which is another deck panel, is also coupled to the top surface of two opposing inner wall formwork on which the deck support is installed, and when the deck support bar is bent while the inner wall formwork is not dismantled, it is long. Since the deck panel closely contacted between the top surface of the formwork panel and the slab bottom cannot be lowered with the deck support bar, the narrow deck support side side panel 26Aaa is used as the deck panel.

Unlike the above example, as shown in FIG. 12, unlike the fixed support 24A of the deck support 24 standing upright on the upper surface of the base bar 22 and the support base 23 installed on the bottom surface, It is also conceivable to have a single-axis deck support 24 'in which a flow support 24B is coupled to a shortened fixed support 24A' having a reduced length.

In this case, a plurality of support (S3) for supporting the deck support bar 25 is required.

The present invention formwork structure made as described above is made through the following series of installation and dismantling.

Installing a foundation bar on the floor along a boundary between the floor and the wall; A step of vertically installing a deck support on an upper surface of the foundation bar where the left and right corners of the two opposing walls and at least one intermediate part equally divides the two corners; Interposing a support base between the bottom and bottom of the protrusion of the deck support and adjusting the uprightness of the deck support; Place the bottom of the long formwork panels on the top surface of the foundation platform so that all the front surfaces of the plurality of long formwork panels are in close contact with the wall surface along the wall surface to form the same plane and the sides of the adjacent long formwork panels are in close contact with each other. Forming an inner wall formwork (21) by connecting pins between the bottom of the long formwork panels, between the left and right adjacent long formwork panels, and the long formwork panel and the deck support; Securing the flow support above the deck support to the highest height; Connecting the bottom surfaces of the two kinds of side panels along the upper surface of the inner wall formwork with the long formwork panels connected left and right; A deck support bar is installed on two opposing inner wall formworks so that bottom ends of the two ends are in close contact with each other on a pair of opposing inner wall molds, and the respective ends of the flow support and the deck support bar are detachably coupled to each other; ; An installation process comprising placing a plurality of deck panels on the upper surface of a plurality of deck support bars installed in parallel with each other and connecting the two side panels with each other to form a deck for slab construction;

After curing of the poured concrete, disassembling the inner wall formwork by releasing the long formwork panels; Lowering the flow support of each deck support; Separating the upper guide bars coupled to the flow support to rotate the flow support together with the support of the deck support bar toward the front downward to incline the support of the deck support bar and to lower the height of the middle part; Dismantling the deck by uncoupling the deck panels placed on the deck support bar and two side panels connected thereto; Separating the deck support bar from the upper surface of the flow support; Installation and dismantling of the present invention formwork structure is made through a dismantling process consisting of dismantling the deck support, the base bar and the support base.

At this time, the plurality of connecting pieces (C) of the two inner wall formwork and the support bolts for fixing the deck support (24) of the two inner wall formwork facing each other with the wall interposed between the long formwork panel and the deck in the state embedded in the wall By cutting the connection side end with the support side, the long formwork panel and the deck support are separated from the cured wall.

In addition, the inner wall formwork and the deck support can be installed alternately together.

In other words, the inner wall formwork and the deck support may be installed by setting the deck support on the upper side of the base bar of one corner and then standing the long formwork to the next deck support installation position and installing the deck support again.

However, when a short-length deck support 24 ′ having a short length is used instead of the deck support 24 standing upright on the upper surface of the foundation bar 22, the process of installing and dismantling the formwork is somewhat different.

That is, since the lower end of the single-sided deck support 24 'is installed in a state of being coupled to the inner wall formwork in the state of floating in the air, the inner wall formwork in close contact with the wall surface except for a plurality of upper portions of the two opposing walls on which the shortened deck support is to be installed. After installing the first, the combined length of the single-axis deck support in the upper part of the two opposing wall without the long formwork panel, the width and length of the wall between the lower side of the short deck support and the upper surface of the foundation bar than the long formwork panel Small compact formwork panels (not shown) are combined.

At this time, the sum of the length of the small formwork panel and the length of the shortened deck support is equal to the length of the original deck support 24, the width of the small formwork panel is the same as the width of the shortened deck support.

In addition, the installation process of the support base support hole 23 in close contact with the bottom surface of the protrusion ET of the deck support 24 is omitted, and the connection pins and the embedded bolts with the elongated formwork panels adjacent to the embedding bolt B '( Since the shortened deck support 24 'can not withstand the load given by the deck and the slab concrete only by the force of B'), the deck support bar bottom and the bottom of the deck support bar to support the deck support bar after the deck support bar 25 is installed. Installing a plurality of supports (S3) between the bottom surface is added.

In addition, the dismantling of the plurality of supports is added at the time of disassembly, but the dismantling of the support base is omitted as in the case of Sully.

In the formwork according to the present invention made as described above, instead of the long formwork panel, a formwork panel stacked up and down conventionally may be used, and the sequence of the above may be changed according to construction conditions.

As described above, since the deck panels are supported by a deck support bar having excellent rigidity, a large number of supports that are conventionally installed to support the deck panels are not required or the number is greatly reduced, thereby greatly reducing the installation time of the formwork. As a result, the deck support bar is lowered and the deck support bar is bent so that the deck is dismantled very easily and conveniently.

In addition, since the deck support and the deck support bar are made of metal and are detachably assembled by a coupling means such as a bolt-nut, they have sufficient economical efficiency even though the initial manufacturing cost is increased due to high recyclability. Shortening and ease of use can reduce the overall construction cost and labor cost.
