Description

Non-bearing Reinforced Concrete Wall Structure and Constructing Method

The present invention relates to the installation structure and installation method of the concrete non-bearing wall cast concrete, specifically, the vertical load between the upper and lower floor slabs of each floor in a multi-storey building, such as a multi-storey apartment house, villa or building, such as an apartment By constructing non-bearing walls (non-structural walls) that are not subjected to on-site casting concrete, the problems of the prior art of constructing non-bearing walls using drywall, namely, high cost and difficulty in quality control, and short and short-term deflection of floor slab The present invention relates to the installation structure and construction method of cast-in-place concrete non-bearing wall to solve the occurrence of play between drywall and floor slab, cracks and defects between junctions between drywall.

In multi-storey buildings, such as apartments, villas or buildings, such as apartments, there is a non-bearing wall that does not receive vertical loads between the upper and lower floor slabs of each floor. Conventionally, drywall was used as a non-bearing wall. In other words, in the past, a non-bearing wall was constructed by vertically installing a dry wall made of lightweight panels, lightweight concrete, or the like, vertically between the upper and lower floor slabs of the floor, which was already installed. An example of a lightweight wall used as a non-bearing wall is disclosed in Korean Patent Publication No. 10-1127930.

By the way, the problem of the prior art of building a non-bearing wall using a dry wall in this way is that the construction cost is a lot of first. In the case of drywall, not only is the price of the product itself expensive, but it must be transported to each floor in the form of a finished product. In the case of a high-rise, the cost of transportation may be increased, and damage may occur in the transportation process. Because of this, handling is very difficult and expensive accordingly.

In particular, when using such a drywall, problems caused by the long and short-term deflection of the floor slab also occurs seriously. Short-term deflection inevitably occurs in floor slabs. The problem of this short-term deflection is more serious in the columnar flat plate structure in which the upper floor slab is supported only by the pillars without the sideways installation. When the drywall is installed vertically between the upper and lower floor slabs after the upper and lower floor slabs of the floor are installed, there is a gap between the drywall and the upper and lower floor slabs due to the short-term deflection of the floor slabs. There is a problem.

Long-term deflection also causes a big problem. Long-term deflection occurs in the upper and lower floor slabs over time. With drywall installed between the upper and lower floor slabs, long-term deflection in the upper and lower floor slabs When it occurs, the vertical wall force acts on the drywall, so that cracks occur at the joints connected to the drywalls in the transverse direction, or the wallpaper, which is attached to the surface of the drywall, is torn, or the like. The gap between the lower floor slab and the upper and lower sides of the drywall is generated again.

In addition, conventional drywall is pre-fabricated with lightweight materials, making it difficult to install household items such as televisions on the drywall, which is not only susceptible to external shocks, but also to leaks and fires. There are disadvantages.

See Republic of Korea Patent Publication No. 10-1127930 (announced on March 23, 2012).

The present invention was developed in order to solve the problems of the prior art of installing a non-bearing wall on each floor of a multi-family house using a factory-produced drywall as described above, specifically, to build a non-bearing wall It is aimed at reducing costs, having no transport and handling difficulties, and making it easy to install and install.

In particular, the present invention is to prevent the play between the non-bearing wall and the upper and lower floor slab, and the upper and lower floor slab due to the deflection of the upper and lower floor slab, even if the short and short sagging occurs in the upper, lower floor slab It is an object of the present invention to provide a technique for constructing a non-bearing wall that can prevent the load-bearing wall from breaking or cracking.

Furthermore, it is an object of the present invention to provide a technique for constructing a non-bearing wall having sufficient strength to hang a household article such as a television or the like, and resistant to external shocks, leaks or fires.

In order to achieve the above object, in the present invention, a non-bearing wall is installed between the upper floor slab and the lower floor slab of the building, the non-bearing wall is manufactured by cast-in-place concrete; Between the bottom slab at the top or bottom of the non-bearing wall, a buffer isolator that can absorb the deformation by stretching is provided; In the vertical slab generated in the floor slab is all absorbed by the compression deformation of the buffer isolator is provided cast-in-place concrete non-bearing wall installation structure characterized in that the vertical load is not applied to the non-bearing wall.

In addition, in the present invention, as a method of constructing a non-bearing wall between the upper floor slab and the lower floor slab of the building, a pair of vertical formwork for forming both sides of the non-bearing wall is spaced apart by the thickness of the non-bearing wall It is installed upright on the floor slab, and the slab formwork for the construction of the upper floor slab horizontally installed on the top of the vertical formwork, and then cast concrete in the inner space of the vertical formwork to form a non-bearing wall; Between the bottom slab at the top or bottom of the non-bearing wall, a non-bearing wall is formed between the bottom slab with a buffer isolator capable of absorbing deformation by expansion and contraction. Provided is a site-cast concrete non-bearing wall construction method characterized in that the absorbed by the compression deformation so that the non-bearing wall is a structure in which the vertical load does not act.

In the present invention described above, after installing the anti-stick material on the bottom floor slab, the vertical formwork is installed on the anti-stick material, and when placing concrete in the interior space of the vertical formwork, the height of the buffer isolation material is left to be installed Filling concrete between vertical formwork only; Inserting and installing the buffer isolator on the upper surface of the concrete filled in the vertical formwork, and then placing the concrete on the upper and the slab formwork of the buffer isolator to form an upper slab; The cushioning isolation material may be installed between the upper end of the non-bearing wall and the upper floor slab, and the anti-sticking material may be installed between the lower floor slab and the non-bearing wall.

In the present invention, in the state in which the slab formwork is horizontally installed on the top of the vertical formwork, a pair of guide angles are installed at the corners where the vertical formwork and the slab formwork are connected to each other; Filling the concrete such that the upper end of the non-bearing wall is positioned between the vertical portions of the pair of guide angles when the concrete is filled between the vertical molds to the height where the portion to which the buffer isolation material is to be installed remains; The cushioning isolation material may be installed to be fitted between the upper surface of the concrete and the pair of guide angles filled between the vertical formwork.

On the other hand, in the present invention as described above, there is a connecting member disposed in the thickness direction of the non-bearing wall between the pair of guide angles, a pair of guide angles may be configured to be connected to one member by the connecting member , The buffer isolator is made of a plate-like member made of a soft elastic material and the cutting line is formed in the center; The buffer isolator may be bent downward along the cutting line when the concrete is poured, it may have a configuration that is restored horizontally again by the elasticity when the concrete is completed.

On the other hand, in the present invention, in a state in which the vertical formwork is installed upright on the bottom floor slab, the buffer isolator is arranged to be placed on the bottom floor slab at the bottom of the vertical formwork; By placing concrete on the cushioning isolation material and constructing the non-bearing wall and the upper floor slab, the buffer isolating material is installed between the lower end and the lower floor slab of the non-bearing wall, and the upper and upper floor slabs of the non-bearing wall are integrally formed. You can also stay connected.

According to the present invention, since the non-bearing wall is constructed in the form of cast-in-place reinforced concrete, it is possible to install not only household articles such as televisions but also heavy weights by hanging on the walls, unlike the non-bearing walls made of conventional drywall. Not only very strong impact. It also has the advantage of excellent durability against leakage and fire.

In addition, the non-bearing wall according to the present invention can reduce the material cost required to build a non-bearing wall because it is cheaper than the conventional dry wall, it is possible to pour concrete to build a column or to build an upper and lower floor slab At this time, since the non-bearing wall can be constructed at the same time, there is no difficulty in carrying and handling as well as it can be easily installed and installed.

In particular, in the non-bearing wall according to the present invention, since both long and short sag in the vertical direction occurring in the bottom slab is absorbed by the compressive deformation of the buffer isolation material, the force due to the sagging of the bottom slab does not act on the non-bearing wall. Therefore, the breakage or damage of the non-bearing wall is prevented from occurring, and the play does not occur between the non-bearing wall and the floor slab.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its essential structure and operation are not limited thereby.

1 shows a state in which a non-bearing wall 1 is constructed between the upper floor slab 10 and the lower floor slab 20 using a site-cast concrete according to the first embodiment of the present invention in one floor of a building. A schematic front view is shown and FIG. 2 shows a schematic cross sectional view along the line AA of FIG. 1.

Non-bearing wall 1 according to the present invention is made of concrete, the inside of the reinforcing steel 13, such as reinforcing bars or wire mesh for reinforcement can be reinforced. Due to the deflection of the upper floor slab 10 or the lower floor slab 20, a play is generated between the non-bearing wall 1 and the floor slabs 10 and 20 while preventing the load from being applied to the non-bearing wall 1. In order to prevent this, the buffer isolation material 2 is provided in the upper side surface or the lower side surface of the non-bearing wall 1 of this invention. In addition, in the present invention, in order to make the non-bearing wall 1 and the upper floor slab 10 discontinuous with each other, or to make the non-bearing wall 1 and the lower floor slab 20 discontinuous with each other, the non-bearing wall 1 An attachment preventing material 3 for preventing attachment to the upper bottom slab 10 or the lower bottom slab 20 may be installed on the upper side or the lower side of the bottom slab 10.

Looking at the first embodiment of the present invention shown in Figures 1 and 2 in more detail, the upper surface of the non-bearing wall (1) is provided with a buffer isolator (2), attached to the lower surface of the non-bearing wall (1) The prevention material 3 is provided. That is, in the first embodiment of the present invention, the buffer isolator 2 is present between the upper surface of the non-bearing wall 1 and the upper floor slab 10, and the lower surface and the lower floor slab of the non-bearing wall 1 are present. The adhesion preventing material 3 exists between (10). The buffer isolator (2) may be made of a material that can absorb deformation by stretching, for example, made of foamed resin, synthetic resin, rubber, etc. to sufficiently absorb the deflection of the floor slab by compression deformation. It is made of a member having a thickness so that it is disposed in the transverse direction along the width of the non-bearing wall (1).

As described above, in the state in which the non-bearing wall 1 according to the present invention is installed, the upper end and the top floor slab 10 of the non-bearing wall 1 are not only in a discontinuous state by the buffer containment material 2, but also the top floor slab. The long and short deflections in the vertical direction occurring in (10) are all absorbed by the compressive deformation of the buffer isolation material (2). Therefore, the load acting on the upper floor slab 10 in the present invention having the configuration as described above is transmitted to the lower layer through the column 30 and the vertical load does not act on the non-bearing wall (1), according to the load action It is possible to prevent breakage or cracking of the non-bearing wall 1. In addition, since the vertical sag of the upper bottom slab 10 is absorbed by the buffer isolator 2, although the upper surface of the non-bearing wall 1 maintains a straight line, the lower surface of the upper bottom slab 10 is curved due to the sag. However, the play does not occur between the non-bearing wall 1 and the upper floor slab 10.

On the other hand, when the buffer isolation material 2 is provided on the top surface of the non-bearing wall 1, the bottom surface of the non-bearing wall 1 may be formed integrally with the lower bottom slab 20 in series. As described above, when the lower side surface of the non-bearing wall 1 and the lower floor slab 20 are continuously integrated, the concrete for the lower floor slab 20 and the non-bearing wall 1 can be poured at a time. This has the advantage of being easy.

However, as in the first embodiment described above, the lower surface and the lower floor slab 20 of the non-bearing wall 1 may be in a discontinuous state by the adhesion preventing material 3. Recently, since the non-bearing wall is often dismantled according to the user's space utilization needs, the lower surface of the non-bearing wall 1 and the bottom floor slab 20 are discontinuous in order to facilitate the removal of the non-bearing wall. It is desirable to bring it to a state. To this end, in the first embodiment described above, the anti-sticking material 3 is attached to the lower side surface and the lower portion of the non-bearing wall 1 so that the lower surface of the non-bearing wall 1 and the upper surface of the lower floor slab 20 do not adhere to each other. It is installed between the floor slab 20. That is, as shown in FIGS. 1 and 2, the anti-stick material 3 is present on the lower surface of the non-bearing wall 1 and the upper surface of the lower floor slab 20 so that the lower surface and the bottom of the non-bearing wall 1 are present. The slab 20 is separated from each other.

Since the upper surface of the non-bearing wall 1 is completely isolated from the upper bottom slab 10 by the buffer isolator 2 so that the vertical load transfer to the non-bearing wall 1 is not performed at all, the self-weight of the non-bearing wall 1 Should eventually be transferred to the bottom floor slab 20 through the bottom surface of the non-bearing wall 1. The attachment preventing material 3 makes the lower surface of the non-bearing wall 1 and the bottom slab 20 discontinuous with each other as described above, while allowing the load of the non-bearing wall 1 to be transferred to the bottom floor slab 20. Therefore, the anti-sticking material 3 is preferably made of an incompressible material, and examples thereof include vinyl, film, sheet paper, and the like.

On the other hand, when the lateral side (lateral side) of the non-bearing wall 1 is adjacent to the pillar 30, as shown in FIG. 1, the non-bearing wall 1 may be integrated with the pillar 30 continuously. However, the non-bearing wall 1 and the pillar 30 may be in a discontinuous state without being integrated with each other. Thus, in order to make the non-bearing wall 1 and the pillar 30 discontinuous, the adhesion preventing material 3 may be provided also between the transverse side surface of the non-bearing wall 1 and the pillar 30.

Next, each step of the method for constructing the non-bearing wall 1 according to the first embodiment of the present invention will be described with reference to FIGS. 3 to 9. 3 is a schematic perspective view of a state in which the plate-shaped vertical formwork 5 and the slab formwork 6 are installed for the construction of the non-bearing wall 1, and the vertical formwork 5 at the position AA of FIG. And a perspective view of the slab formwork 6 cut away.

First, a pair of plate-shaped vertical formwork 5 for forming both sides of the non-bearing wall 1 is installed upright on the lower floor slab at intervals equal to the thickness of the non-bearing wall 1. At this time, when it is necessary to prevent the adhesion between the lower side surface of the non-bearing wall 1 and the lower floor slab 20, as described above, an anti-stick material 3 such as a film is installed on the lower floor slab 20. After that, the vertical formwork 5 is erected thereon. In addition, to reinforce the non-bearing wall 1, the reinforcing steel 13 may be disposed in the interval between the pair of vertical formwork (5). On the other hand, in the case where the non-bearing wall 1 is continuous with the pillar 30 and is constructed integrally, in order to install the vertical formwork 5 as above, one side of the vertical formwork 5 in the transverse direction is produced. By connecting to the formwork (not shown) for the space, the space between the vertical formwork (the non-bearing wall is formed) and the space in which the column is to be communicated with each other. However, in the case where the non-bearing wall 1 is not continuous with the pillar 30, the anti-stick material is provided on one side of the vertical formwork 5 facing the pillar. At this time, the anti-sticking material (3) used is preferably wood that can be erected vertically. Finishing plates (not shown) are also installed on the other side of the vertical formwork 5 in order to pour concrete.

When the vertical formwork 5 is installed in this way, the slab formwork 6 for the construction of the upper floor slab is installed horizontally at the top of the vertical formwork 5, and subsequently the concrete in the interior space of the vertical formwork 5 It is poured to create a non-bearing wall (1). FIG. 4 is a schematic perspective view of a state in which concrete 4 is poured at the interval between a pair of vertical formwork 5 subsequent to FIG. 3, and FIG. 5 is a schematic enlargement of the circle B portion of FIG. 4. The figure is shown. In pouring concrete into the vertical formwork 5, the concrete is not filled up to the height of the upper surface of the slab formwork 6, but is filled only up to the height in which the buffer isolation material 2 is to be installed, as shown in FIG.

Subsequently, the buffer isolation material 2 is inserted and installed on the upper surface of the concrete 4 filled in the vertical formwork 5. FIG. 6 is a schematic perspective view showing a state where the buffer isolation material 2 is inserted into the upper portion of the pair of vertical molds 5 after FIG. 5, and FIG. 7 is a schematic enlargement of the circle C portion of FIG. 6. The figure is shown. As shown in the figure, when inserting and installing the buffer isolator 2 on the upper surface of the concrete filled in the vertical formwork (5), it is preferable that the buffer isolator 2 does not protrude above the upper surface of the slab formwork (6). Do. This is to avoid a decrease in the thickness of the upper bottom slab due to the buffer isolator 2 in the portion where the buffer isolator 2 is installed.

FIG. 8 is a schematic perspective view showing a state in which the upper floor slab 10 is formed by pouring concrete according to the thickness designed on the slab formwork 6 following the state of FIG. 6, and FIG. 9 shows a vertical formwork 5. ) And a schematic cross-sectional view along the line DD of FIG. 8 for the portion where the slab formwork 6 at the top is joined. In the embodiment shown in FIGS. 3 to 9, in order to prevent the fall of the non-bearing wall 1, the connecting reinforcement 91 protrudes over the upper surface of the concrete 9 filled in the vertical formwork 5. That is, the lower portion of the non-bearing wall 1 is embedded in the concrete 4, the connecting reinforcement 91 is further protruded above the height of the upper surface of the slab formwork 6, the protrusion of the connecting reinforcement 91 Top is embedded in the concrete of the upper floor slab 10. The connecting reinforcing bars 91 may be provided in plural numbers at intervals in the width direction of the non-bearing wall 1. Although the non-bearing wall 1 is separated from the upper bottom slab 10 by the buffer containment material 2 at the upper end and the lower bottom slab 20 by the attachment preventing material 3 at the lower part, When the connecting reinforcing bar 91 is provided, the connection between the upper bottom slab 10 and the non-bearing wall 1 is made to a minimum to prevent the fall of the non-bearing wall 1. That is, it is possible to exert a resistance to the shear force causing the conduction of the non-bearing wall (1). However, the connecting reinforcing bar 91 is not essential and may be omitted.

When the concrete (4) poured into the vertical formwork (5) is cured to produce a non-bearing wall (1), and the concrete poured on the upper surface of the slab formwork (6) is cured to complete the construction of the upper floor slab (10) Formwork (5) and slab formwork (6) will be demolded.

On the other hand, in the construction of the non-bearing wall 1 by the construction method according to the present invention as described above, it is also possible to use the guide angle (8). 10 to 14 are views corresponding to FIG. 5, respectively, the slab formwork on the top of the vertical formwork 5 in the second embodiment of the present invention in which the non-bearing wall 1 is constructed using the guide angle 8. It is an enlarged view of the part to which (6) is connected. As shown in FIG. 10, in the state where the slab formwork 6 is horizontally installed on the upper end of the vertical formwork 5, the vertical formwork 5 and the slab formwork 6 are bent in an L-shape at the corners connected to each other. Install the guide angle (8). The guide angle 8 may be installed in pairs of two, and each pair may be installed at each corner. As shown in FIG. 11 in the state where the guide angle 8 is installed at the corner, the shock absorber 2 is Placing concrete in the vertical formwork (5) to the height remaining portion to be installed to make a non-bearing wall (1), as shown in Figure 12, the buffer isolator (2) on the top of the concrete filled in the vertical formwork (5) Install it. Therefore, the upper end of the non-bearing wall 1 and the buffer isolation material 2 are in between the vertical portions of the pair of guide angles 8.

After the buffer isolator 2 is installed, as described above, the upper floor slab 10 is formed by pouring concrete to the thickness designed on the slab formwork 6, and when the concrete is hardened, the formwork is demolded. FIG. 13 shows a state in which the concrete of the upper floor slab is poured, and FIG. 14 shows a state in which the formwork is demoulded following the state of FIG. 13.

The use of the guide angle 8 in this way is very advantageous for the fall prevention of the non-bearing wall 1. The non-bearing wall 1 is completely separated from the upper floor slab 10 by the buffer containment material 2. In the above configuration, the corner portion between the top of the non-bearing wall 1 and the upper floor slab 10 is provided. Since the guide angle 8 is attached and disposed, and a part of the upper end of the non-bearing wall 1 is sandwiched between the pair of guide angles 8, in the second embodiment, the conduction moment is applied to the non-bearing wall 1. Even if, the resistance moment against it is generated, the non-bearing wall 1 is in a very stable state to conduction. In particular, the use of the guide angle 8 is very useful for minimizing the deterioration of the buffer isolator 2 because it prevents the buffer isolator 2 from being exposed to air.

On the other hand, as mentioned above, when it is necessary to dismantle the non-bearing wall 1 for space utilization, the guide angle 8 that the upper end of the vertical portion of the guide angle 8, that is, the lower surface of the upper bottom slab 10 touches. Cutting the part, the buffer isolator 2 is easily exposed, and cutting or removing the buffer isolator 2 allows the non-bearing wall 2 to be physically completely separated from the upper floor slab 10. Since it becomes a state, it will be in the state which can demolish the non-bearing wall 1 easily. Even when using the guide angle (8) as described above, if necessary, it is possible to further install the connecting reinforcement 91 as described above.

On the other hand, in the installation of the guide angle (8) in this way, in the embodiment described above, the guide angle (8) bent by the letter "A" was used in pairs, each independently existed, but the connecting member (8) between the guide angle (8) By arranging 81, a pair of guide angles 8 may be made of one member by the connecting member 81. FIG. 15 shows a schematic enlarged view corresponding to FIG. 10. Specifically, in the third embodiment shown in FIG. 15, the thickness of the non-bearing wall 1 between two guide angles 8 bent in the letter “A” is shown. The connection member 81 arrange | positioned in the direction exists, and the pair of guide angles 8 are connected by the connection member 81 to one member. At this time, a height at which the cushioning isolation material 2 can be fitted must be secured above the connection member 81.

 The connecting member 81 may be formed of a rod member. In this case, the connecting member 81 is provided at intervals in the width direction of the non-bearing wall 1. The connecting member 81 may be formed of a plate member as shown in the embodiment shown in the drawing, in this case, when the connecting member 81 is formed of a plate member, the concrete 4 poured from the top of the vertical formwork 5 The through hole 82 is formed to be easily filled in between.

When the two guide angles 8 form one member connected to each other by the connecting member 81 as described above, it is very easy to install at the connection corner between the vertical formwork 5 and the slab formwork 6. That is, as shown in Figure 15, it is because the guide angle 8 is to be provided so that the connecting member 81 is located between the vertical formwork (5). FIG. 16 corresponds to FIG. 11 showing a state in which the non-bearing wall 1 is made by filling the concrete 4 in a state where the guide angle 8 having the connecting member 81 is installed on the vertical formwork 5 as described above. An enlarged view is shown. After the connecting member 81 is installed, the concrete 4 is poured into the vertical formwork 5 so that the non-bearing wall 1 is formed, at which time the connecting member 81 is formed of the non-bearing wall 1. It is preferable to be embedded in the concrete 4. This is for the guide angle 8 to exert a function of preventing the non-bearing wall 1 from being conducted as described above. That is, when the connecting member 81 is embedded in the concrete of the non-bearing wall 1, the upper end of the non-bearing wall 1 is eventually sandwiched between two guide angles 8, and thus, as described above, There is an opposing moment of resistance that results in an extremely stable state of conduction. FIG. 17 is an enlarged view corresponding to FIG. 12 showing a state where the cushioning isolation material 2 is fitted above the connecting member 81, and FIG. 18 is a view illustrating a state in which the upper bottom plate slab 10 is poured. An enlarged view corresponding to 13 is shown. Since the process after installing the guide angle 8 and placing concrete for the non-bearing wall 1 is the same as in the above-described embodiments, the description thereof will be omitted.

On the other hand, in the embodiment shown in Figures 15 to 18, the guide angle 8 is shown as having a stud 84 is further provided in the horizontal portion. The studs 84 are embedded in the upper bottom slab 10. When the studs 84 are provided, the guide angle 8 and the upper bottom slab 10 are firmly integrated. These studs 84 may be equally provided in the guide angle 8, which consists of the individual 자 bending members shown in FIGS. 10 to 14.

Next, a fourth embodiment of the present invention will be described with reference to FIGS. 19 to 22. 19 is a vertical formwork (5) and the slab formwork (6) is installed in order to construct a non-bearing wall according to the fourth embodiment of the present invention, the buffer isolation material (2) is installed on the upper surface of the slab formwork (6) Is a schematic perspective view corresponding to FIG. 3. 20 to 22 are schematic enlarged views of a circle E portion of FIG. 19, respectively.

In the fourth embodiment shown in Figures 19 to 22, the buffer isolator 2 is configured to easily penetrate the concrete (4) for the non-bearing wall (1). Specifically, in the fourth embodiment shown in the drawings, the buffer isolator 2 is made of a soft elastic material such as a rubber plate, and consists of a plate-shaped member having a perforation line 27 formed in the center thereof. The perforation line 27 may be saw-toothed as illustrated in the figure, but may be made in a wave shape or various other shapes. In this way, in the case of using the buffer isolation material 2 having the cut line 27 formed therein, the vertical formwork 5 and the slab formwork 6 are installed in the construction of the non-bearing wall 1, and the slab formwork 6 In order to cover the space between the vertical formwork 5 on the upper surface, a buffer isolator 2 having the above cut line 27 is provided. As shown in FIG. 20, when the concrete 4 for the non-bearing wall 1 is poured from the top of the slab formwork 6, the buffer isolator 2 is cut out by the weight of the concrete 4. As it is bent downward along the concrete 4 is passed through the buffer isolator 2 is poured into the vertical formwork (5). When the casting of the concrete 4 is completed, the buffer isolator 2 is restored horizontally again as shown in FIG. 21 by elasticity, and in this state, the buffer isolator 2 and the slab formwork ( 6) concrete is poured into the upper surface of the upper floor slab 10 is produced. When the upper floor slab concrete is poured into the upper surface of the slab formwork 6, the buffer isolator 2 is supported by the non-bearing wall concrete 4 located below it, so that it can maintain a horizontal shape. do. 19 to 22, when using the buffer isolator (2) that automatically maintains the horizontal level after the completion of the pouring of the concrete (4), before the concrete for the non-bearing wall (1) is buffered in the formwork in advance It is possible to install the isolator (2), so that concrete is poured over the slab formwork (6) in succession to form concrete bearing walls (1) by pouring concrete into the vertical formwork (5) with the buffer containment material (2) installed. By pouring the upper floor slab 10 can be formed. That is, since it is not necessary to perform the installation work of the buffer isolator 2 between the concrete pouring work for the formation of the non-bearing wall 1 and the concrete pouring work for the formation of the upper floor slab 10, the non-bearing wall 1 Concrete pouring for the formation of) and concrete pouring for the formation of the upper floor slab 10 can be carried out continuously without interrupting the work in the middle, thus exhibiting the advantage that the work can proceed quickly and efficiently.

As described above with reference to the first to fourth embodiments, in the present invention, the non-bearing wall 1 is constructed by concrete. Therefore, unlike the conventional non-bearing wall made of drywall, not only household goods such as televisions but also heavy weights can be installed on the walls, and not only very strong against external shocks. It also has the advantage of excellent durability against leakage and fire.

In addition, the non-bearing wall 1 according to the present invention can reduce the material cost required to build a non-bearing wall because it is inexpensive compared to the conventional drywall, concrete to build a column or to build an upper, lower floor slab When placing the non-bearing wall can be built at the same time, there is no difficulty in transport and handling, as well as has the advantage that can be easily installed and installed.

Above all, in the non-bearing wall 1 according to the present invention, there is no problem due to the short and long deflection of the upper and lower floor slabs. As described above, in the present invention, the long and short sagging of the vertical direction occurring in the upper bottom slab 10 is formed of the buffer isolator 2 existing between the upper end of the non-bearing wall 1 and the upper bottom slab 10. All are absorbed by compressive deformation. Therefore, even if deflection occurs in the upper bottom slab 10, the force thereof does not act on the non-bearing wall 1, thereby preventing damage or damage of the non-bearing wall 1 to occur. In particular, the lower surface of the upper floor slab 10 is curved due to deflection, while the upper surface of the non-bearing wall 1 maintains a straight line, even though the clearance between the non-bearing wall 1 and the upper floor slab 10 is maintained. The effect which does not occur is exhibited.

In the above description, although the buffer isolation material 2 is disposed between the upper end of the non-bearing wall 1 and the upper bottom slab 10, the non-bearing wall 1 is completely separated from the upper bottom slab 10. In the present invention, the buffer isolation material 2 may have a structure disposed between the lower end of the non-bearing wall 1 and the lower bottom slab 20. That is, the upper end of the non-bearing wall 1 is continuous with the upper bottom slab 10, and the lower end of the non-bearing wall 1 is completely isolated from the lower bottom slab 20 by the buffer isolation material 2. It may have a structure.

23 to 25, the upper end of the non-bearing wall 1 is continuous with the upper bottom slab 10, and the lower end of the non-bearing wall 1 is connected to the lower bottom slab 20 by the buffer isolator 2. FIG. 23 is a front view corresponding to FIG. 1, FIG. 24 is a schematic cross-sectional view taken along the line FF of FIG. 23, and FIG. 25 is shown in FIG. Fig. 24 is a schematic enlarged view of the position of the circle G portion of Fig. 24 for the case of using the guide angle. For convenience, Figure 25 is shown in a state in which the vertical formwork 5 is installed for convenience.

As shown in FIGS. 23 and 24, the upper end of the non-bearing wall 1 is continuous with the upper bottom slab 10, and the lower end of the non-bearing wall 1 is lowered by the buffer isolator 2. In order to construct a structure that is completely separated from the ()) to install a buffer isolator (2) on the bottom floor slab 20, the vertical formwork (5) and the top floor slab (10) for the non-bearing wall (1) Install the slab formwork (6) for each. Since the transverse width of the buffer isolator 2 eventually corresponds to the thickness of the non-bearing wall 1, the vertical formwork 5 is installed so that the buffer isolator 2 is sandwiched between a pair of vertical formwork 5. do. Thus, after installing the buffer isolation material (2), the vertical formwork (5) and the slab formwork (6), the concrete structure is poured from the top, the non-bearing wall (1) and the upper floor slab (10) is a continuous structure It will be constructed to be. If necessary, as shown in the above-described embodiment, the reinforcement 13 may be disposed in the vertical formwork 5.

On the other hand, even in the case of the embodiment shown in Figs. 23 and 24, the non-bearing wall 1 may be integrated with the column 30 continuously, but as shown in the figure, the transverse side of the non-bearing wall 1 and the column ( The non-bearing wall 1 and the pillar 30 may be in a discontinuous state without being integrated with each other by providing the anti-sticking material 3 between them. In this case, the anti-sticking material 3 installed between the lateral side of the non-bearing wall 1 and the pillar 30 may be made of wood having a thickness or the like, as shown in the drawing.

In the construction of the non-bearing wall 1 as described above, as shown in FIG. 25, the horizontal portion of the guide angle 8 is placed on the lower floor slab 20, and the vertical portion of the guide angle 8 is vertical formwork 5. A pair of guide angles 8 are disposed on the bottom floor slab 20 in a form of being in close contact with the inner surface thereof, the vertical formwork 5 is set up, and the buffer isolation material 2 is installed between the guide angles 8. Afterwards, the concrete 4 may be poured between the vertical formwork 5 to construct the non-bearing wall 1.

As described above, the upper end of the non-bearing wall 1 is continuous with the upper bottom slab 10, and the lower end of the non-bearing wall 1 is completely isolated from the lower bottom slab 20 by the buffer isolation material 2. In this structure, the non-bearing wall 1 is suspended from the upper floor slab 10, but is separated from the lower floor slab 20 by the buffer containment material 2, so that the upper floor slab 10 Even if deflection occurs in the non-bearing wall 1 due to the short-term deflection, the deflection of the non-bearing wall 1 is absorbed by the buffer isolation material 2, so that no force is transmitted to the lower floor slab 20. Unfavorable loads also do not act on the non-bearing wall 1. Also in this case, there is an effect that play does not occur between the non-bearing wall 1 and the lower floor slab 20.
