Description

Core form moveable formwork {CORE WALL TYPE OF SLIDING FORM}

The present invention relates to a core-type mobile formwork and a method for constructing the wall surface of a building using the same, in particular, while simultaneously moving the formwork to the four-sided wall surface while being moved up and down without disassembling the formwork. The present invention relates to a core-type mobile formwork and a construction method using the same, which enable accurate construction and can be installed accurately and conveniently.

In general, the core wall method, which is used when forming a wall surface of a building, refers to a method of forming a wall to support stress applied to the vertical wall in the vertical direction instead of four pillars. The wall method is not only to increase the strength of the building because the four wall body is formed into a single structure, but also the method is simple, and is used as an effective construction method for buildings with the same vertical structure as the apartment.

However, the conventional core-wall construction method is effectively used only in one layer by using a ready-made formwork standard form, but the effect is halved because it is not used continuously.

That is, there are various kinds of buildings, but there are various problems due to the movement of the formwork in building a high-rise building while having the same planar structure vertically and vertically as the location of the wall like an apartment.

For example, until now, in general, when building a building, a formwork for wall is installed, a formwork for slab is installed, reinforcing steel bars, and the concrete is placed on the wall and the slab at the same time.

Therefore, after completing one layer, the wall surface and the slab of the layer are simultaneously formed, so that the vertical space is blocked by the slab. Therefore, in order to use the formwork used again, it must be disassembled even in the case of the core-wall formwork as described above, and then moved to the already formed slab, and then assembled and used again. In addition to the problem, the assembly and disassembly of the basic unit to reduce the volume and weight of the material for the convenience of movement, because of the loss of formwork and temporary materials during this work process and the location of the formwork is not constant Because the hole is used during the landfill attachment process, there is a disadvantage that the damage of the material is large and the consumption is large and it is uneconomical.

In addition, the above-described construction method has a cost problem in disassembling the slab and then moving it back to use for assembly. For example, about 60-65% of the construction cost is spent as the frame construction cost, and the frame construction portion occupies the frame construction cost. The ratio is 55-60%.

This problem arises because the wall and slab of the building are molded at the same time. In other words, when the wall forming one layer is formed, the wall is simultaneously formed with the slab forming the electric wire, and thus the vertical and horizontal spaces are blocked by the slab.

On the other hand, as described above, without forming the wall and the slab at the same time, the wall of the upper layer is formed first, and then by forming the slab of the lower layer, it is possible to secure the vertical space up and down, and the formwork to the upper layer through the space thus secured There is a sliding formwork which allows the formwork to be used continuously while moving. This sliding formwork is developed and used by a German company called Toka.

In the conventional method using a sliding formwork, a large formwork corresponding to one wall surface is attached to the form setting machine, and the form setting machine is used to complete the formwork of the wall. Then, the form setting machine is moved to another wall surface to move the form setting machine to another wall surface. In order to set the formwork of the other wall in order to set the formwork of the other side to complete the formwork of four sides, this conventional method has a number of problems.

For example, when the formwork is completed through the above-described method, there are methods of simultaneously constructing the wall and the lower slab and separately constructing the wall and the lower slab with a parallax. After installing the construction, the concrete is placed in the slab and solidified. After removing the construction, a hole is formed. This hole is used as a rotation node where the two sides meet at a right angle, but in the wall structure, the rotation node In the construction of the lower slab and wall at the same time as in the former case, it is necessary to support the wall formwork in the air to fix the wall formwork on the slab formwork. You need a piece of scrap metal that will allow you to If the work is difficult and complicated to secure and the place between the walls is narrow, it is difficult to fix the large formwork to the form binding hole. In this case, not only a part of the formwork flows out into the concrete slab, but also a wall panel uses one set of formwork on one wall, so it is impossible to simultaneously work to set the formwork on four walls at the same time. There is a problem in the arrangement of, and not only has the disadvantage that the process is delayed, but also because the formwork for forming each wall has to be set separately at a time difference, it is difficult to set the right and left formwork to match exactly will be.

That is, since the conventional sliding die-setting apparatus as described above is designed to support only one wall formwork, it is not possible to set four wall formwork at the same time, and after setting the formwork for forming one wall, Since it is necessary to set the formwork for forming the wall, it is difficult to accurately balance the left and right when setting the formwork individually, so that the four walls cannot be made precisely and cleanly without shifting each other.

Therefore, when the slabs are formed in the displaced walls in the horizontal direction, the points of contact between the slabs and the walls become inconsistent, so that there is a problem such as cracks occurring at the points of inconsistency, and each wall is individually. The disadvantage was that a cumbersome work process that required the formwork to be set was required.

In the present invention to solve the problems described above, it is possible to adjust the size of the room, while setting the formwork on the four walls at the same time, the point where the neighboring walls and walls and slabs meet each other It is an object of the present invention to provide a core-type mobile formwork which can not only prevent the occurrence of misalignment, thereby preventing the occurrence of abnormal cracks in the building, but also reduce the labor cost for the construction of the formwork.

The core wall type movable formwork of the present invention for achieving the above object is a rectangular movable formwork set in which four formwork walls are integrally connected, and is installed inside the formwork set to simultaneously form four walls of the formwork set. Formwork holding frame to support by connecting the movable formwork set and the formwork fixing frame to change the support force between the formwork set and the fixing frame and to form a space to be able to perform the preliminary work for binding the formwork within the formwork It is composed of a variable connecting jack and a support bracket fixed to the wall of the building to support the fixing frame from the bottom.

The support bar is installed in addition to the variable connecting jack between the formwork set and the formwork fixing frame, and the support bar is installed in the formwork fixing frame, and through a sliding socket provided with a fixing bolt for locking the position of the support bar. Combined.

A gasket bearing is installed to help the support bar inclined under the load of the sliding socket to move smoothly, and the form set is composed of an inner fixed wall and a corner wall coupled to both ends of the fixed wall. While being fixed, these fixed walls and corner walls are coupled to be separated from each other.

The variable connecting jack consists of a threaded threaded rod and a diamond-shaped variable frame coupled to the screw rod, and the variable frame is fixed to the die set and the formwork fixing frame, respectively.

The mobile formwork of the present invention having the structure as described above, when forming a wall such as a room or a living room in a high-rise building, such as an apartment, the structure of each floor is the same, the thickness and size of the wall at the bottom floor Without releasing the formwork frame, the variable connecting jack is used to detach the formwork from the wall, and then moves upward as it is. Then, the formable contact jack is used to make the form close to the position. Since it can be formed continuously, it is possible to reduce the labor and labor costs of dismantling and moving the formwork when building a high-rise building.

In addition, when the form set according to the present invention is used, since a large space is formed in the center of the form in the vertical direction, there is an effect that can be utilized as a space for moving an object up and down through this space.

And, among other things, since the form set according to the present invention can set the formwork on four walls at the same time, the construction can be simplified, and the labor cost can be greatly reduced, and the occurrence of cracks due to the unbalance of the wall It can easily solve problems such as cracks caused by incorrect setting of walls and slabs.

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

1 is a cross-sectional view showing a state of constructing the outer wall and the inner wall of the building at the same time using the movable formwork according to the invention, Figure 2 is a plan view showing the removable formwork according to the invention separately, Figure 3 is FIG. As a cross-sectional view along the line A-A of the mobile formwork in accordance with the present invention in a vertical state, as shown in these figures, the mobile formwork according to the invention is a rectangular form in which four formwork walls 1 are integrally connected. The movable form set (2) and the formwork fixing frame (3) installed inside the form set (2) to simultaneously support all four walls (1) of the form set (2), the movable form set (2) And a variable connecting jack (4) for connecting between the formwork fixing frame (3) and the support force between the formwork set (2) and the fixing frame (3), and as shown in FIGS. 5) Is fixed is composed of the supporting bracket (6) that unsupported at the bottom of the flange (3).

As shown in FIG. 8, the form set 2 includes a fixed wall 21 and a corner wall 22 that form a frame of the form set 2 while the variable connecting jacks 4 are connected to each other. The fixed wall 21 and the corner wall 22 are fixedly coupled to each other by pins or the like at the connection surface thereof.

Thus, as shown in the drawing, the form wall 1 has a fixed wall 21 disposed at its middle portion and a corner wall 22 connected to both edges thereof.

On the other hand, the corner wall 22 can be produced in the same manner as when manufacturing a general steel formwork, except that the connection line end surface of the fixed wall 21 in the connection surface of the fixed wall 21 and the corner wall 22 It is preferable to fabricate inclined toward the corner wall 22 so that the formwork is easily taken out when demolding.

And, as shown in the figure, the form fixing frame 3 is formed so that the size of the internal cross-sectional area is smaller than the form set 2, the predetermined distance between the form fixing frame 3 and the form set (2) The space (S) should be formed, which is necessary for the operator to enter and work between the formwork frame (3) and the form set (2), and the space of about 50 to 60 cm It is desirable to allow this to be formed.

In addition, as shown in FIGS. 3 and 4, the formwork fixing frame 3 is composed of an upper fixing frame 31 and a lower fixing frame 32 formed in a quadrangular shape, and these upper and lower fixing frames 31 and 32 are It is a structure connected to each other by the jack fixing base 33 arrange | positioned in the vertical direction.

Accordingly, the upper and lower sizes of the formwork fixing frame 3 are determined according to the height of the wall, while the upper and lower fixing frames 31 and 32 also separately manufacture the corner frame 34 and the intermediate frame 35, and these corners By varying the length of the frame 34 and the intermediate frame 35, the plane size of the formwork frame 3 can be adjusted.

In addition, between the upper and lower fixing frame 31 and 32 and the jack fixing table 33, the upper and lower supporting members 36 are inclined and held so as to increase the support strength, and the corner frames of the upper and lower fixing frames 31 and 32 are supported. 34, the horizontal support material 37 is installed diagonally to support the stress applied to the corner frame 34.

Then, the jack fixing stand 33 is installed at equal intervals about two pieces on each side of the formwork fixing frame (3) to couple the variable connecting jack (4) to the jack fixing stand (33).

Therefore, the form set 2 can be moved uniformly in the horizontal direction by the connecting jack 4. Here, the connecting jack (4) is only a mechanism necessary to move only the form set (2), and does not support the stress of the concrete when the concrete is placed, the formwork is correct position by the connecting jack (4) After moving to the inside and outside the formwork is fixed by the tie bolts, both the formwork is fixed by the tie bolts, while the stress of the concrete itself is supported by the frame and the tie bolts attached to the formwork Will be.

On the other hand, the variable connecting jack (4) for connecting between the die set (2) and the formwork fixing frame (3) is a plurality of at least two on the threaded rod 41 formed in the opposite direction to each other at intervals by a predetermined length A variable frame 42 having a rhombus shape is installed to be movable along a screw thread. The variable frame 42 is pivotally connected by connecting points at both ends thereof with pins 43. Screw pipes 44 and 45 provided with female threads are respectively provided at upper and lower connecting points in the middle thereof, and the screw pipes 44 are coupled to the screw threads of the screw rods 41.

Accordingly, when the knob 46 provided on the upper end of the screw rod 41 is turned, the screw rod 41 is rotated and the screw of the variable frame 42 being screwed to the screw rod 41. The pipes 44 and 45 move up and down along the threaded rod 41. Since the threads of the threaded rod 41 to which the upper and lower threaded pipes 44 and 45 are held are formed in opposite directions, As a result, the variable frame 42 of the rhombus shape is widened or narrowed between both connecting pins 43 along the left and right width directions as the intervals along the vertical direction of the upper and lower screw pipes 44 and 45 become narrow or widen. It will work to lose.

In addition, connecting brackets 47 and 48 are provided at both ends of the variable frame 42, respectively, and the connecting jacks 4 are provided through the connecting brackets 47 and 48 to the wall 1 of the form set 2, respectively. And fixed to the formwork fixing frame (3), respectively.

Therefore, the width of the variable frame 42 is variable as the handle 46 of the connecting jack 4 is rotated, thereby adjusting the holding force between the form set 2 and the form fixing frame 3.

On the other hand, between the formwork set (2) and the formwork fixing frame (3) in addition to the connecting jack (4) can be installed additional support bar (7), the fixed support bar (7) is the formwork set (2) It is possible to reinforce the stress acting between the die and the frame fixing frame 3, which is difficult to support only by the connecting jack (4), and after the formwork is installed, it must be held to prevent the formwork from moving or flowing. It is preferable to install and use the bar 7.

This fixed support bar (7) is also connected to the formwork set (2) through a bracket (71) installed at its tip, while maintaining a constant distance between the formwork set (2) and the formwork fixing frame (3) To this end, it is desirable to be able to adjust the length, for this purpose, as shown in Figures 5, 6, 7, vertical bar 37 for connecting the upper and lower corners of the upper and lower fixing frames 31 and 32 up and down; The sliding socket 8 is intersected at the portion where the upper and lower fixing frames 31 and 32 are connected to each other so that the fixed support bar 7 can be inserted into the sliding socket 8 and the sliding socket 8 8) to fix the support bar (7) is adjusted in length by installing a fixing bolt (81).

Thus, while adjusting the distance between the tip of the form set 2 and the tip of the form fixing frame 3 in parallel, the length of the support bar 7 moving into the sliding socket 8 is adjusted, and then the fixing is performed. When the bolt 81 is tightened, the support bar 7 is fixed in the adjusted state.

On the other hand, the sliding socket 8 not only facilitates the movement of the support bar 7, but also smoothly in a state in which the support bar 7 under the load of the form set 2 is struck downward and moved obliquely. In order to be able to move while sliding, it is preferable to install and use a gasket bearing 82 at the inlet and the outlet of this sliding socket 8.

Therefore, when the support bar 7 in a state of being pushed down under the load moves along the sliding socket 8, the support bar 7 can smoothly move while performing frictional friction through the gasket bearing 82.

Then, the assembly of the form set (2) and the form fixing frame (3) of the present invention made as described above, as shown in Figure 10, 11 and 16, the wall surface of the building by the support bracket (6) ( 5) the support bracket 6 is first, the support bracket (6) is a model of the right triangle, while the bottom side is upward and the vertex is downward, as shown in Figure 16, the upper and lower ends Fasten a plurality of bolts (61, 62) to the wall surface (5).

The support bracket 6 of the present invention coupled as described above has a surface having a predetermined width thereon, so that the form set 2 and the formwork fixing frame 3 are fixed using the surface as the working footrest 63. You can do things like let it be.

The upper end of the support bracket 6 is provided with a socket 61 through which a hole of a predetermined depth is drilled. The socket 61 and the vertical bar 33 of the die fixing frame 3 are provided in the socket 61. 38) is fitted to fit.

On the other hand, the support bracket (6) is not used in the bottom wall surface of the foundation work in the initial state of work is used to directly fix the formwork to the floor, formwork fixing frame (3) and formwork set (2) according to the present invention As the wall is made upwards using, you can fix it to this wall.

Where the support bracket 6 is installed, the holes for installing the bolts 61 and 62 may be drilled in advance or may be connected to the die-binding hole formed in advance.

Therefore, the formwork frame 3 coupled to and supported by the support bracket 6 fixed to the wall surface is supported in a space having a predetermined height.

On the other hand, in the formwork according to the present invention, since the empty space (S) is formed therein, as shown in Figure 2, the object can be moved vertically and vertically through this space (S).

Therefore, it can be very useful to secure the space for moving up and down the objects needed when building.

Next, the construction method and sequence for constructing the building using the formwork according to the present invention as described above will be described with reference to FIGS. 19 to 22. First, in assembling the set of the fixing frame 3, in the work space of the site Secure a certain space, assemble each part to the size of the room designed in the building, install the form set (2), reinforce the rebar on the filled site, and move the frame set assembled as above by the crane to the workshop. .

In order to be able to continue the work after completing the work of one floor, first put a bolt into the form fastening hole, tighten the support bracket (6) to the tie bolt, and then tighten the support bracket (6) to the finished wall. To the support frame (6) and then install the formwork settle (2). And using the connecting jack (4) to move the die set (2) back and forth to secure a work space.

On top of the formwork fixing frame (3) is installed a workbench for concrete work or moving passage.

Then, look at the assembly installation process, the method according to the present invention after making the working reference frame, such as dust foundation or slab, the outside of the outer wall proceeds the existing formwork construction method, reinforce the wall reinforcement and install the assembly formwork.

At this time, assembling formwork of the inner wall, the adjacent formwork sets the dismantling or lifting time differently in consideration of the reinforcing bar or landfill facility, and lifts one wall to lift the other formwork after the work, which becomes convenient.

After lifting, the installation procedure is first installed in accordance with the form binding hole drilled in the wall (5). In case of using a general slab, the fixing frame (3) is assembled there and the tie bolts are fitted. Fixing the form set (2) by using the connecting jack (4) close to the wall to be molded, and then tighten the tie bolt.

And, if you look at the manufacturing installation of the slab, demolished the assembled formwork of the pre-constructed wall and lifted it to the top, and then removed the temporary landfill material (such as Schiropol) indicating the position of the slab, and then the concrete work with the slab formwork and There is a method of forming a slab without using a formwork using a half slab.

The work order of the half slab can be performed simultaneously with the construction of the upper wall and the lower slab so that the wall and the lower slab can be worked simultaneously.

According to the results of the work stress review and work review of each part of the new construction method, it is possible to work even if the slab position is left blank when constructing the wall part immediately, and if the slab concrete is used, It's not worth mentioning that the joints of the edges are strengthened, but working with the slab works well.

Therefore, the work of wall formwork can be continued regardless of the slab work, but considering the convenience of work and lifting work and the schedule of the slab work, the work distance from the slab work to the next floor after the wall work is about 3 stories. It is good to leave.

However, when using the half slab, the lower slab work may be performed simultaneously with the wall formwork.

And in the work order, we first look at the assembly of the wall reinforcing bars, before installing the wall formwork, we need to assemble the reinforcing bars for the wall. It is convenient to install by lifting with a tower crane, there is no problem even if the reinforcing bars directly assembled in the field, but there is a problem because of the narrow working space.

Next, look at the formwork manufacturing and installation, the formwork used here should be produced with the following functions.

① The outer side of the outer wall should use the existing method, but for fixing the wall, the formwork should be lifted and fixed with tie bolts. Therefore, the position of the tie bolt hole at the top of the formwork and the fixing bracket hole at the bottom should be well adjusted.

② The prefabricated formwork should be adjustable by moving the formwork back and forth from the assembly frame to secure the working space.

③ The workbench should be installed on the assembly frame set. After assembly, fix it to the fixing frame and use it until completion.

④ Form tie is made longer than wall thickness.

Looking at the procedure for installing the form set of the present invention manufactured as described above, ① the external exterior formwork installation, ② retaining wall reinforcement, ③ the internal prefabricated formwork set installation, ④ styropole slab separator installation, ⑤ insert the form tie, ⑥ move the formwork with jack , ⑦ concrete placement, ⑧ disassembly after curing, ⑨ installation and adjustment of bracket at the same time as lifting, ⑩ wall formwork dismantling layer slab work order continuously.

Next, look at the lifting method of the prefabricated formwork set,

① Loosen the tie bolts, move the form set a little with the tower crane, and bit the form with the jack.

② Arrangement of internal tie bolt and anchor bolt

③ Lifting after removing bracket bolt

④ Fix the bracket bolts and fasten the assembly frame.

⑤ Push the formwork forward to tighten the tie bolts.

In the lifting equipment, tower crane and triangular derrick are manufactured about 8.5 ~ 9m, and the derrick is installed by crane and then lifted by chain block.

Next, look at the details of the construction method according to the invention as follows.

1) Balconies and balustrades are poured with slabs, and the connections with the walls are constructed with concrete joints (Fig. 1).

2) Maguri wall construction (construction of side walls, etc.) (Fig. 1)

Finally, the construction of the slab will be described.

1) Construction with general formwork

In this construction method, since the construction of the vertical wall proceeds quickly, when the slab concrete is laid and the construction time is the same as that of the slab with a long curing period and formwork period, ②③④, the length of the formwork and temporary materials is long, thus securing a lot of temporary materials. This can be an uneconomical construction.

Therefore, it is necessary to shorten the shelf life of the formwork, and to disassemble and disassemble it conveniently, so the slab work cannot be used in the process of dismantling and transporting.

① shortening of dies

If you replace the shells to recover the formwork during curing, there is a risk of sag and there is a risk of cracking. Therefore, the formwork of the slab is vertically installed in a small form so that the formwork can be removed without removing the group. Supports should be provided to support the formwork and separate support points.

② It takes a lot of time because the reuse of formwork should be taken into consideration, and as a result, the concrete strength progresses partially without demolding, considering the progress of the concrete.

2) Half slab construction (after forming formwork PC)

① Lift the prefabricated formwork by crane and move it to the next place.

② Lift and install wide slab (half fish)

③ slab reinforcement

④ Placing walls and lower slabs at the same time after installing prefabricated formwork

On the other hand, for convenience when lifting the die set (2) and the mold fixing frame (3) using a lifting machine as described above, as shown in Figure 14, the hook in advance in the corner of the mold fixing frame (39) (39) ) Can be used conveniently.

On the other hand, when the wall of the building is made by the method according to the present invention, only the vertical wall surface 5 is first formed, and of course, the slab must be formed in the middle according to the number of floors of the building. At the point P at which the slab is to be made in the middle of forming, as shown in Fig. 17, the upper and lower wall surfaces 5 are supported only by the reinforcing bars 9 without placing concrete, and the upper and lower wall surfaces 5 are supported. After it is completely made, the slab is formed by reinforcing and concrete pouring to form the slab 10.

As described above, the mobile formwork according to the present invention has the following characteristics compared to general formwork,

① By using large formwork, the wall surface is smooth and the wall surface with less warpage or irregularities can be made, so it is possible to do high quality work. This makes the finishing work easy and the following work is easy and effective.

② Since the demoulding and lifting is done through the equipment, the construction is smooth and easy, and it can be assembled mechanically, thus reducing the labor cost because the use of manpower is reduced.

③ The assembly and disassembly cost is low and the air is faster.

④ The loss or damage of materials is greatly reduced and the number of reuse is increased.

⑤ Construction cost is low and economical.

⑥ Since the vertical and horizontal surfaces are uniform, the adhesive part of the finishing material is good and the work is easy, fast and of good quality.

⑦ Fast air and high accuracy

⑧ Since the wall is installed first, concrete maintenance is easy and effective when it is very cold or very hot.

In other words, when the concrete is very hot when the formwork portion is well maintained compared to the exposed surface, it has the advantage of high sealability of the outer wall to prevent the temperature of the concrete to change rapidly. And when it is very hot, the wall formwork blocks direct sunlight or wind to prevent premature dehydration, prevents plastic cracking, the long duration of the wet state, and the use of fabric warmers can be fixed to the wall formwork. The effect will be maximized.

⑨ Since the installation pipe is constructed without slab, it is easy to work and there is no need to install the fire protection compartment inside the duct.
