Description

WALL STRUCTURE MANUFACTURING METHOD USING PRECAST FRONT WALL PANEL AND PRECAST BACK WALL PANEL}

The present invention relates to a wall structure manufacturing method using a precast front wall and a precast back wall. More specifically, the present invention relates to a method of manufacturing a wall structure, which is capable of constructing a more economical and efficient wall structure by using a precast wall and a cast concrete.

1 is a construction of a conventional wall structure associated with the present invention.

It can be seen that the wall structure is composed of the bottom plate 10, both walls 20 and the top plate (30).

The bottom plate 10 is usually constructed to have a predetermined thickness by placing on-site concrete 15, and usually after both walls 20 are first installed, they are installed by on-site concrete pouring between the lower portions of both walls. do.

In the case of FIG. 1, both walls 20 are illustrated in the form of retaining walls in which the wall 22 is hinged to the bottom plate 21. In this case, the bottom plate 10 is formed by the connecting reinforcing bar 14 and the coupler 16. ) And both walls 20 are integrated with each other.

The wall 20 is constructed by connecting a plurality of wall segments to each other in the construction direction (the longitudinal direction) of the box structure.

At this time, the method of connecting the wall in the longitudinal direction is usually connected by a variety of connecting means such as shear key, connecting bolt and nut.

However, the most important point in the connection of the longitudinal walls is whether the connection performance of the wall segments can be sufficiently secured, and whether the constructability can be improved by minimizing the number of installation of the wall segments in the range of manufacture and transport. .

First of all, in the case of the connection performance, the method of connecting a plurality of wall segments may inevitably cause inequality even though the quality control is good because many connection joints have to be formed even though multiple connection methods are used. Management is inevitably difficult, which means that there are limitations in structurally integrating a plurality of wall segments in the longitudinal direction.

In addition, many wall segments are prefabricated at the factory. The closer the distance between the production site and the construction site is, the easier the transportation, the higher the constructability and the economical, but the size that can be transported by using a vehicle is inevitably limited.

In general, the height of a plurality of wall segments is limited, but a length of about 1 m to 2 m in the longitudinal direction based on approximately 3 to 5 m before and after is to be connected to each other. However, as the length of one wall segment becomes longer, the weight increases, so the size of the wall segment that can be transported and constructed is inevitably limited in consideration of transport constraints and site construction.

Furthermore, when the wall segment is precast, the bottom plate 10 is generally hinged. In this case, the wall segment is erected and supported on the bottom plate so that the bottom plate and the wall segment are connected to each other. It may be advantageous that the bending moment does not occur, but the self-weight including the top plate and the bending moment due to earth pressure are inevitably concentrated on the wall segment and the bottom plate, thereby increasing the thickness of the wall segment.

In this way, the connection between the bottom plate and the wall segment can be hardened in any way. However, since the wall segment is precasted, the method of tightening the bottom plate with the bolt (such as bolts) is disadvantageous in terms of cost and workability. do.

In addition, the connection joint is inevitably formed in the longitudinal connection with the wall segment, but there is a problem in that it is not easy to secure the actual watertightness even when using an exponential means in such a connection joint.

Furthermore, the top plate 30 may use a precast method or a site casting method using formwork, such as both walls, depending on the site conditions, the precast top plate 32 so that the prestress is introduced by the tension member 31 in the transverse direction. It can be seen that. At this time, the precast top plate 32 is installed on both walls, and then takes the method of finishing with the cast-in-place concrete 33.

Therefore, the present invention in the construction of the wall structure

The precast walls have a cross-sectional shape formed to have flexural stiffness that can effectively resist the working load, but they are appropriately mixed with cast-in-place concrete to minimize the self-weight of the precast walls. It is possible to secure enough economic feasibility and to structurally integrate the wall with the top plate and the bottom plate in the longitudinal direction, but it is structurally more stable, and the wall and the bottom plate can be easily hardened to effectively distribute the bending moment acting on the wall and the bottom plate. An object of the present invention is to solve the provision of a wall structure manufacturing method using a precast front wall and a precast rear wall.

In order to achieve the above technical object

First, in order to construct a wall having a constant thickness, the present invention is a wall connecting reinforcing bar between the precast front wall and the precast rear wall in a state where the precast front wall and the precast rear wall are separated from each other and lying on the floor. One of the rebars will be made to protrude. Further, the wall connecting bars of the precast front wall and the wall connecting bars of the precast back wall are connected to each other while the wall connecting bars are in contact with the precast back wall above the precast front wall which protrudes upward. By setting up the precast front wall and the precast back wall constrained to each other so as to be set up, it is possible to drastically shorten the air by preventing reinforcement work inside the wall.

Secondly, the space between the precast front wall and the precast back wall is cast in place so that the inner wall concrete is poured so that the precast front wall and the precast back wall are vertically set to each other to use the wall connecting bars. To be synthesized.

Third, bent end blocks are formed at both ends of the precast front wall and the precast rear wall of the present invention so as to be in contact with each other in the longitudinal direction, and the precast front wall in the longitudinal direction by the cast-in-place concrete. The precast back wall is integrated with each other to ensure sufficient longitudinal connection performance and watertightness between the precast front wall and the precast back wall.

Furthermore, the bent end block is a portion where the precast front wall and the precast rear wall are in contact with each other, such that the bent end blocks that are in contact with each other are connected to each other by, for example, splices.

Fourth, the lower part of the precast rear wall of the wall structure of the present invention is such that the opening is formed by the support column so that the main reinforcing bars of the precast front wall and the internal reinforcing bars of the precast rear wall extend toward the bottom plate through the opening. The bottom plate concrete is poured so that the wall structure and the bottom plate can be firmly connected to each other.

Fifth, the upper plate and the precast front wall and the precast rear wall may be rigidly formed by integrating the upper plate on the upper part of the precast front wall and the precast rear wall by using the main reinforcement of the inner wall of the wall.

According to the present invention, the wall structure is mixed with the precast method and the cast-in-place concrete method. The precast front wall and the precast back wall are especially manufactured to minimize their own weight so that they are not affected by the limitations of the wall that can be manufactured, transported, and constructed. However, in the field, it is possible to construct a slimmer wall structure by placing the internal wall concrete and the bottom plate concrete without reinforcement in the wall and through the longitudinal connection performance of the wall and the rigid connection with the bottom plate.

In addition, according to the present invention, the wall structure is connected to each other by simply connecting the precast rear wall to the precast front wall by using the wall connection reinforcement and the bent end block, and the wall structure should be installed so that the self-supporting position can be installed at the site. This can be omitted completely.

In addition, while the precast front wall and the precast rear wall according to the present invention can minimize the thickness by pre-formed internal wall reinforcement, the bent end block has a front plate and a back plate of the precast front wall and the precast rear wall. By acting as a support for supporting the structure it is possible to provide a cross-sectional wall structure having a more effective rigidity against the working load.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise.

[Load Action of Precast Front Wall and Precast Back Wall]

Figure 2 shows the loading action diagram of the precast front wall 110 and the precast rear wall 120 of the present invention.

First, the precast front wall 110 and the precast rear wall 120 are formed with bent end blocks 113 and 123 formed at the upper and lower ends of the front plate 111 and the rear plate 121, respectively, as shown in FIG. 3A. As a structure, it can be seen that the wall connecting reinforcing bars 133 protrude from the rear and front surfaces of the front plate 111 and the rear plate 121.

In this case, in FIG. 2, the front plate 111 and the rear plate 121 will be referred to as a wall slab, and the bent end blocks 113 and 123 will be referred to as a wall support.

Accordingly, when a load is applied to the wall slab, the wall slab is curved to bend. At this time, if the height is divided into H1 and H2, it will be bent and bent by the load acting on the wall slab with the height of H1.

Basically, internal reinforcing bars (cast reinforcing bars, power reinforcing bars, wall connecting reinforcing bars) formed in the wall slab are to reinforce the wall slab sufficiently to resist the applied load.

Furthermore, the wall support serves as a longitudinal point portion for supporting the wall slab on which the load acts on the rear surface.

That is, the wall support serving as the longitudinal point portion is supported by the wall support of the back plate in contact with each other as shown in Figure 3a and the front plate and the back plate is constrained by the wall connecting reinforcement 133 with each other, so the reaction force as the load acts It is possible to act so that the wall girder can act as a longitudinal point on the load acting on the wall slab.

After all, the wall slab of the present invention is formed by the wall slab (front plate, back plate), the wall support (bending end block) and the internal reinforcement to minimize the thickness of the wall slab, even if the weight is small enough to be sufficient bending rigidity for the load action You can get it,

Furthermore, the wall connecting reinforcement 133 is pre-arranged in the precast front wall 110 and the precast rear wall 120 and connected to each other in the space between the precast front wall and the precast back wall 120, thereby precast front wall 110. ) And the precast rear wall 120 serve to constitute each other.

In addition, the wall connecting reinforcing bars 133 may be formed (not shown) through rebars passing through the precast front wall 110 and the precast back wall 120, and thus, the precast front wall 110 and the precast back surface may be simply provided. The walls 120 may be restrained from each other.

[Precast front wall and precast rear wall (110,120) of the present invention]

3A and 3B are perspective views of the precast front wall and the precast back wall 110 and 120 of the wall structure 100 of the present invention, and FIG. 3C is arranged between the precast front wall and the precast back wall 110 and 120. It shows the coupling of the wall connection reinforcement 133.

First, the wall structure 100 is disposed such that the precast front wall and the precast back walls 110 and 120 are laterally contacted with each other as shown in FIG. 3B, and the precast front wall and the precast back wall as shown in FIG. 3C. The wall connecting reinforcement 133 is exposed to the space, and the inner wall concrete 140 is poured as shown in FIGS. 4A and 4B so that the wall connecting reinforcement 133 connected to each other is embedded.

First, the precast front wall 110 and the precast back wall 120 are precast concrete members set to face each other as shown in FIG. 3A.

First, the precast front wall 110 is formed of a front plate 111 and a wall connecting reinforcing bar 133. The front plate 111 forms a front surface of the wall to be manufactured in the form of a reinforced concrete plate having a predetermined thickness. do.

When the front plate 111 is lifted, for example, the front plate 111 is formed to have a thickness enough to resist self weight, thereby minimizing its own weight.

To this end, the front plate 111 is preferably made of reinforced concrete in the form of a plate having a constant longitudinal width (B) and the cross-sectional height (H), both ends are longitudinally connected to the precast front wall (110) And bent end blocks 113 and 123 are formed to be connected to the precast rear wall.

Accordingly, the outer surface of the bent end block 113 located at the longitudinal connection portion is in contact with each other in the longitudinal direction as shown in Figs. 3b and 3c by the longitudinal connection member 128, such as a connecting bolt, a fastener such as a nut or a tension member. It is to be fastened to each other to be compressed.

In addition, the rear end of the bent end block 113 is in contact with the front end of the bent end block 123 of the precast rear wall 120 disposed to face each other as shown in FIGS. 3B and 3C. The front wall 110 and the precast back wall 120 is to enable a stable transverse connection.

In addition, as shown in FIG. 3A, the inner wall reinforcement 130 is disposed in advance in the front plate 111.

The internal wall reinforcement 130 is the main reinforcement 131 and the reinforcement reinforcement 132 (indicated by the dots) in the longitudinal direction and vertical direction will be possible to reinforcement by the reinforcement details, and in advance in the field because the work is done in the factory Reinforcement work is excluded.

At this time, the wall connecting reinforcing bar 133 is protruded from the rear surface of the front plate 111 so as to be connected to the inner wall of the wall so as to function as the connecting bar of the front plate and the back plate.

Accordingly, the present invention connects the wall connecting reinforcement 133 to each other between the precast front wall 110 and the precast rear wall 120, and the precast front wall 110 and the precast wall reinforcing bar 133 are embedded. The wall structure 100 may be formed by pouring the inner wall concrete 140 by in-situ casting between the cast rear walls 120.

Therefore, when the precast front wall 110 and the precast rear wall 120 are manufactured at the factory, the wall connection reinforcing bars 133 are brought into the site in the protruding state, so that only the inner wall concrete 140 is installed in the site without reinforcing bars. By pouring, the wall structure 100 can be easily constructed.

The reinforcement bar 132 is installed so that the reinforcement so as to extend in the longitudinal direction horizontally with respect to the main reinforcing bar 131 is spaced up and down.

At this time, the wall connecting reinforcing bar 133 is formed so as not to be drawn out from the internal reinforcing bar, the precast front wall 110 and the precast rear wall 120 and through-holes in contact with each other and the precast front wall 110 Both ends 110 and 120 may be formed to be constrained to each other by fastening and fixing both ends to the precast front wall 110 and the precast back wall 120 by penetrating through the precast back wall 120.

In this case, in particular, the main reinforcing bar 131 of the precast front wall 110 is to extend vertically along the precast front wall 110, but in the lower part via the opening between the support pillars 125 of the precast back wall 120 It is arranged to extend toward the bottom plate so that when the bottom plate concrete is poured is buried.

As a result, the present invention suggests that the main reinforcing bar 130 and the main reinforcing bar 131 and the wall connecting reinforcing bar 133 are all pre-arranged in advance when the precast front wall 110 is manufactured, thereby minimizing field work. Can be.

As a result, the internal wall reinforcement 130 of the present invention

First, the main reinforcement 131 and the reinforcement reinforcing bars 132 and wall connection reinforcement including the reinforcement in advance in the factory so that no other reinforcement work in the field,

Second, in the precast front wall 110 composed of a wall slab and a wall girder serves as a reinforcing bar to reinforce the front plate. In other words, it is possible to manufacture a thinner front plate by reinforcing the front plate formed of concrete.

Third, it is to act as a composite reinforcing bar (wall connection reinforcement) that can be synthesized integrally with the inner wall concrete and the front plate to be described later.

Fourth, in particular, the main reinforcing bar 131 serves as a connecting reinforcing bar bottom and the wall unit.

Next, the precast rear wall 120 is also formed by including a main reinforcing bar 131 and a wall connecting reinforcing bar 133 as the rear plate 121 and the inner wall of the wall 130 as shown in FIG. 3A.

That is, the back plate 121 is to form the back of the wall structure 100 to be manufactured in the form of reinforced concrete plate having a certain thickness. The back plate 121 is also the same as the front plate to minimize the weight by forming only a thickness enough to resist the weight when lifting the back plate.

For this purpose, the back plate 121 is also preferably manufactured as a plate-shaped concrete member having a constant longitudinal width and a cross-sectional height, and both ends of the back plate 121 also have a longitudinal connection of the precast back wall 120 like the front plate. In order to form the bent end block 123.

The outer surface of the bent end block 123 is also in contact with each other in the longitudinal direction so as to be fastened to each other by the longitudinal connection member 128, such as fasteners or tension members such as connecting bolts, nuts.

In addition, the front end of the bent end block 123 is in contact with the back surface of the bent end block 113 of the precast front wall 110 disposed to face each other as shown in Figs. 3b and 3c is also used splice (not shown) It is connected to each other to enable a stable transverse connection of the precast front wall 110 and the precast rear wall (120).

The difference between the back plate 121 and the front plate 111 is that the bottom of the back plate 121 is formed to be supported by the column support portion 125, the height of the back plate 121 of the front plate 111 Is to be smaller than the height.

That is, the pillar support part 125 is a vertical column-shaped member spaced apart from each other in the longitudinal direction, and as shown in FIGS. 3B and 4A, the inner wall reinforcement 130 is formed as an opening S, which is a space between the pillar support parts 125. ), The main reinforcing bar 131 is bent and extended to the opening to extend toward the bottom plate 200.

Accordingly, the bottom plate concrete 210 and the wall inner wall concrete 140 may be integrated with each other by the main reinforcing bars 131 to be firmly connected to each other.

Furthermore, the height of the front plate 111 is increased so that when the concrete is laid for the construction of the top plate 300 as shown in FIGS. 3C and 4A, the front plate 111 serves as a formwork and extends to the top plate 300. It is to be able to effectively secure the reinforcement space of the cast iron 131.

Also, as shown in FIG. 3A, the inner wall reinforcement 130 is disposed inside the back plate 121.

The internal wall reinforcement 130 is capable of reinforcement by the reinforcement details as the main reinforcement 131 and the reinforcement reinforcement (not shown) in the vertical direction and vertical direction, and is already done in the factory, so the reinforcement work is excluded in the field.

At this time, the wall connection reinforcing bar 133 is protruded from the front surface of the back plate 121 so as to be connected to the inner wall of the wall so as to function as a connecting bar of the front plate and the back plate.

As described above, the precast front wall 110 and the precast rear wall 120 connect the wall connecting bars 133 with each other, and the precast front wall 110 and the wall connecting bars 133 are embedded. The wall structure 100 may be formed by pouring the inner wall concrete 140 by in-site casting between the precast rear walls 120.

The reinforcement bar 132 is installed so that the reinforcement so as to extend in the longitudinal direction horizontally with respect to the main reinforcing bar 131 is spaced up and down.

Also, the main reinforcing bars 131 of the precast front wall and the precast back wall 110 and 120 are vertically extended along the precast front wall and the precast back wall 110 and 120, but the supporting pillar of the precast back wall 120 is below. Arranged so as to extend toward the bottom plate via the opening between the parts to be buried in the bottom plate when placed.

[Preparation and construction of precast front wall and precast rear wall 110, 120, bottom plate 200 and top plate 300 of the present invention]

Figure 4a is a cross-sectional view of the precast front wall and precast rear wall (110,120) and the bottom plate 200 of the present invention, Figure 4b is a precast front wall and precast rear wall (110,120) and the top plate 300 of the present invention Is the connection cross section of.

First, referring to FIG. 4A, the precast front wall and the precast back wall 110 and 120 are already supported on the ground, and only the wall connecting reinforcing bars 133 and the main reinforcing bars 131 of the inner wall reinforcement 130 are protruded. It is a state formed.

That is, it can be seen that the main reinforcing bars 131 of the precast front wall and the precast back wall 110 and 120 are horizontally bent into the opening S of the precast back wall 120 to extend to the portion where the bottom plate 200 is formed. Can be.

Accordingly, the main reinforcing bar 131 which is disposed on the precast front wall 110 serves as a connection reinforcing bar between the inner wall concrete and the bottom plate concrete.

Installing the formwork (not shown) necessary for this and placing the bottom plate concrete 210 and the interior wall concrete 140 can be installed with the bottom plate and the wall structure naturally. Accordingly, the wall structure and the bottom plate of the present invention are connected to each other in a rigid manner.

Referring to FIG. 4B, after the construction of the bottom plate and the wall structure is completed, a part of the top plate 300 is constructed. That is, the bottom plate, the wall structure and the top plate are formed into a rectangular box structure as shown in FIG. 5D by the construction of the top plate 300. The final construction may be completed, such a top plate may use a top plate by precast or on-site casting, and the top plate may be formed by connecting the upper parts of both wall structures to one top plate and forming two top and bottom plates. It doesn't matter.

At this time (in the case of on-site casting) it can be seen that the upper end of the reinforcing bar 131 reinforcement to the precast front wall 110 is bent toward the top plate 300 to be embedded in the top plate.

[Manufacturing method of wall structure using precast front wall and precast back wall]

5A, 5B, 5C and 5D illustrate a method of manufacturing a wall structure using the precast front wall and the precast back wall of the present invention.

The final construction of the wall structure will be described on the basis of the case of a box-like structure including the bottom plate, both wall structures and the top plate.

First, FIG. 5A illustrates the reinforcement formation state of the inner wall reinforcement 130 in the precast front wall and the precast back wall 110 and 120.

That is, the precast front walls and the precast rear walls 110 and 120 manufactured and imported from the factory are laid on the floor of the site so that the wall connecting bars 133 face upwards.

Accordingly, it can be seen that only the wall connecting reinforcing bars 133 and the main reinforcing bars 131 protrude out of the inner wall reinforcing bars 130 to the precast front walls and the precast rear walls 110 and 120.

The reason for adopting such a process is that a separate wall between the precast front wall and the precast back wall 110 and 120 that is vertically established even if the height of the precast front wall and the precast back wall 110 and 120 is more than 2 m. Reinforcing the internal reinforcing bar becomes very difficult.

In other words, the wall inside the reinforcement 130 proceeds by the manual work by the worker one by one, for example, even if the height is only 2m a temporary copper bar for installing a foothold, such as the worker can work safely, even if the hypothesis such a hypothesis Even if the copper bar is installed, the work efficiency of reinforcing the inner reinforcing bar 130, which is 4 to 5 m in height, is inevitably deteriorated, which inevitably causes a delay in air.

Accordingly, the present invention enhances the efficiency of the reinforcement work of the inner wall reinforcement (130) by reinforcing all of the inner wall reinforcement (130) in advance to the precast front wall and the precast rear wall (110, 120), which are erected in a vertical state. It is to reduce.

The precast rear wall 120 protruding the wall connecting reinforcing bar 133 upward on the precast front wall 110,

The wall connecting bars 133 protruding from the precast rear wall 120 are connected to the wall connecting bars 133 of the precast front wall by using the coupler 126.

Naturally, the bent end blocks of the precast front wall 110 and the precast back wall 120 are also set to be in contact with each other and constrained by splices.

The precast front wall 110 and the precast back wall 120 connected to each other are vertically erected to connect the precast front wall 110 and the precast back wall 120 connected to each other in the longitudinal direction as shown in FIG. 5B. Let's go.

That is, as described above, the longitudinal connection of the precast front wall or the precast rear wall 120 connects the bent end blocks 113 and 123 disposed so that the outer surfaces thereof are in contact with each other in the longitudinal direction, and fasteners or tension members such as bolts and nuts. The precast front wall and the precast back wall 110 and 120 are installed to be connected to each other in the longitudinal direction so that they can be compressed by being fastened to each other by the longitudinal connecting member 128.

At this time, each of the precast front wall and the precast rear wall (110,120) may be conducted by placing pressure when placing concrete inside the cast-in-place concrete wall, but as described above, the bent end blocks (113, 123) facing each other are first split. It is connected by a rice and the wall connecting reinforcing bars 133 are connected to each other by the coupler 126 to restrain each other to more effectively support the pouring pressure.

Furthermore, the ends of the wall connecting reinforcing bars 133 may be bent in a semicircle to overlap each other so as to be connected to each other.

Such restraint plays a very important role in securing stability as the height of the precast front wall and the precast back wall 110 and 120 increases.

At this time, the lower part of the precast rear wall 120 can be confirmed that the opening (S) is formed.

Accordingly, as shown in FIG. 5C, the main reinforcing bars 131 of the precast front wall and the precast rear wall 110 and 120 are bent horizontally downward to extend toward the bottom plate 200 so that the bottom plate is formed using a finishing form (not shown). (200) The bottom plate concrete 210 is placed for construction, and the bottom plate concrete 210 is filled to the lower portion of the precast front wall 110 and the precast rear wall 120 so that the cast iron extending toward the bottom plate ( 131 is to be landfilled.

Next, after the bottom plate concrete is cured or continuously, the inner wall concrete 140 is poured so that the wall connecting reinforcement 133 of the inner wall reinforcement is embedded so that the final wall structure construction can be completed.

Thus, it can be seen that the precast front wall 110 and the precast back wall 120 of the present invention are to be rigidly connected to the bottom plate 200 and to be integrated by the inner wall concrete 140 in the longitudinal direction.

Next, as shown in FIG. 5d, the final upper plate 300 is installed between the upper parts of both wall structures using the upper plate concrete or the like to enable the box structure construction.

As such, the wall structure 100 according to the present invention may be integrally formed with each other in the longitudinal direction while the walls 110 and 120 are firmly connected to the bottom plate 200, and the top plate 300 is also integrally connected with the walls 110 and 120 to be rigid. It can be seen that.

The foregoing description of the present invention is intended for illustration, and it will be understood by those skilled in the art that the present invention may be easily modified in other specific forms without changing the technical spirit or essential features of the present invention. will be.
