Description

Precast panel and structure manufacturing and construction method using the same {PRECAST PANNEL AND STRUCTURE CONSTRUCTION METHOD USING THE SAME}

The present invention relates to precast panels used in walls and pillars of structures. More specifically, economic feasibility can be secured by forming the hollow part without using EPS blocks, and self-weight can be reduced by using a grid-type steel structure that can easily secure bending rigidity in the horizontal and vertical directions. This relates to precast panels that are easy to install by connecting left and right, and methods for manufacturing and constructing structures using them.

Figure 1a shows a construction example of a conventional precast double wall 10.

The precast double wall 10 is manufactured in advance at a factory, etc., and is manufactured so that the wall structure 30 can be constructed by setting it vertically on the upper surface of the base plate 20 first constructed on site.

That is, after setting the two vertical panels 11 to face each other, the two vertical panels 11 are restrained to each other using the truss reinforcement 12 to form an internal space S, which is manufactured to have a certain thickness. It can be seen that a cast double wall (10) is used.

Accordingly, compared to those manufactured with a solid cross-section, the self-weight was reduced by an amount equivalent to the volume occupied by the concrete in the internal space (S) based on the same thickness.

Accordingly, after the connecting reinforcing bar 21 drawn out from the upper surface of the base plate 20 is inserted into the internal space (S), concrete (13) is additionally inserted so that the truss reinforcement 12 is embedded in the internal space (S). After constructing the wall structure (30) by pouring and curing it, a floor plate (40) is additionally constructed on the upper surface to integrate the wall structure (30) and the floor plate (40) into a multi-layer structure that combines the wall and floor plate. It can be seen that construction is underway.

However, as a large number of connecting reinforcing bars 21 are drawn out from the upper surface of the base plate 20, they act as an obstacle to the construction movement line. In other words, the precast double wall 10 is usually lifted using a crane (tower crane, etc.) and set to be vertically and laterally connected to each other, but there are cases where the connecting reinforcing bar 21 is located in the crane's work line and becomes an obstruction. In most cases, there was a problem that reduced constructability in setting the precast double wall (10).

In addition, since the precast double wall (10) is manufactured to a height of more than 10M (weighing approximately 20 tons), a separate fall prevention device (51, 52, side support plate, anchor, and mirror) is installed on the lower side so that it can be installed independently during initial setting. (using a photo support) must be installed, but since the fall prevention device 50 must be installed and dismantled for each precast double wall 10, there is a problem in that workability is greatly reduced.

Furthermore, since concrete (C) had to be poured into the internal space of a separate precast double wall (10) at the site, there was a limitation that the advantage of using the precast double wall (10) was negated considering the large amount of concrete pouring work.

In addition, when manufacturing and transporting the precast double wall (10), it is set horizontally and installed vertically through lifting work at the site. Due to the bending moment that occurs during erection and installation, the precast double wall (10) is deformed. In order to manufacture a precast double wall (10) to resist damage due to damage problems, the thickness and amount of reinforcing steel of both vertical panels (11) had to be increased, resulting in an increase in self-weight.

Accordingly, the size of the precast double wall 10 is inevitably limited, and when manufactured in a small size, the number of connection parts increases in the field, so there is a problem that the advantages of the precast method are largely offset.

Figure 1b shows the bending momento of a conventional hollow concrete slab 60.

In other words, the hollow concrete slab 60 forms a hollow part to reduce its own weight. This hollow part usually reduces its own weight by setting an EPS block inside the form and excluding concrete pouring by the volume occupied by the EPS block.

It can be seen that the square pipe 70 can be installed instead of this EPS block to form a hollow part with the square pipe 70.

However, these square pipes 70 are placed to form a hollow portion and are buried in the longitudinal direction of the hollow concrete slab 60, and are not intended to actively improve structural performance, so they are buried inside the hollow concrete slab 60. As much as possible, it can be seen that there is a limit to otherwise contributing to securing the integrity of the adjacent hollow concrete slab 60.

Republic of Korea Patent No. 10-1875043 (Title of invention: Pretensioned hollow concrete slab using square pipes, Publication date: July 6, 2018)

Accordingly, the present invention can secure economic feasibility by forming a hollow part (S1) without using expensive blocks such as EPS blocks, and can provide a grid-type steel structure simply assembled with ready-made H-type steel members. By using a precast panel, it can effectively resist loads in the horizontal and vertical directions (two directions), ensuring sufficient bending rigidity, and minimizing the thickness of the precast panel, which is effective in reducing its own weight. It is a technical problem to be solved by providing a structure construction method using this.

In addition, when the precast panel is constructed in the form of a vertical wall on the upper surface of the base plate, the connecting reinforcing bar drawn out from the base plate may not be used to connect the lower part of the base plate and the precast panel, making it difficult to lift and move the precast panel. This is a technical problem that aims to solve the problem of providing precast panels and structures using them that do not interfere with the work flow and provide construction methods.

In addition, in order to secure the vertical connection performance of adjacent precast panels, top and bottom connectors were used to ensure integrity and watertightness, and a socket connection method was adopted to enable quick multi-directional connection with panel structures adjacent to the left and right, providing economical results. The technical task is to provide precast panels that can efficiently and effectively construct structures using the precast method, and methods for manufacturing and constructing structures using them.

In order to achieve the above problem, the structure construction method using the precast panel of the present invention includes a reinforced concrete panel body having a socket connection portion (S2) formed by connecting flanges spaced apart from each other at both ends; And the H-shaped steel members are installed so that they intersect each other on the same plane in the horizontal and vertical directions in a lattice form to form a hollow part (S1), and the panels are square pipes on the upper and lower surfaces of the H-type steel members in the form of a lattice. It includes a grid-shaped steel structure formed so that the upper and lower connectors extend to the upper and lower surfaces of the precast panel, wherein the grid-shaped steel structure secures bending rigidity against loads acting in the horizontal and vertical directions, and This allows the precast panel and base plate to be connected to each other.

The precast panel of the present invention uses a lattice steel structure in which H-shaped steel members are simply formed in a lattice shape, thereby protecting the precast panel from two-directional loads (horizontal and vertical loads) acting on the precast panel in the horizontal and vertical directions. It can directly resist bending moment and acts as an internal reinforcement of the precast panel. However, by forming the H-type steel members in a lattice shape, a hollow part (S1) is naturally formed to reduce the self-weight of the precast panel. It is possible to provide precast panels and a structure construction method using them that can solve the problem of load resistance performance degradation.

In addition, the precast panel of the present invention does not use an expensive EPS block for the internal hollow part (S1), but rather secures sufficient economic efficiency by using a method of finishing the hollow part (S1) using a hollow part finishing plate. It is possible to provide precast panels and structural construction methods using them.

In addition, because precast panels are installed horizontally, top and bottom, the risk of deformation and damage of two-way precast panels due to vertical installation (standing installation) in the field can be reduced.

In addition, since the precast panel forms an insertion groove in the base plate, for example, and uses upper and lower connectors inserted into the insertion groove to make the precast panel stand on its own, there is a problem of obstruction of work flow caused by protruding connecting reinforcing bars on the conventional base plate. can be solved, thereby dramatically securing constructability and workability.

[Precast panel (100) of the present invention]

FIGS. 2A and 2B are illustrations of the lattice-type steel structure 130 of the present invention, and FIGS. 2C and 2D are schematic perspective views and construction examples of the precast panel 100 of the present invention.

The precast panel 100 is manufactured in large numbers at once in the vertical direction (up and down, vertical direction) by a vertical mold system (not shown), transported in the vertical direction, brought into the site, and then erected vertically. Instead, it is lifted vertically and connected and installed in the up and down and left and right directions.

In addition, it is economical by using a method of finishing the hollow part (S1) using the hollow part finishing plate 120 instead of filling the hollow part (S1) inside the precast panel 100 with expensive EPS blocks. This will help solve the degradation problem.

In addition, since concrete is excluded to the volume occupied by the grid-type steel structure 130 embedded in the reinforced concrete panel body 110 and a hollow portion S1 is naturally formed, the self-weight of the precast panel can be effectively reduced. Let's do it.

At this time, the vertical direction is connected using the vertical connecting material 114 and the panel upper and lower connecting material 132, and the left and right direction is connected using the socket connection part S2 and the lateral connecting material 115.

That is, when connecting the precast panel 100 to the base plate 200, the upper and lower connectors 114 are used to connect and install them. By constructing using the panel top and bottom connectors 132 exposed to the outside from the precast panel 100, unlike in the past, no connecting reinforcing bars protrude from the upper surface of the base plate 200, making it easier to install the precast panel 100. Therefore, it is possible to solve the problem of deterioration of constructability and workability due to obstruction of movement lines.

In addition, referring to FIGS. 2A and 2B, the grid-type steel structure 130 has the function of forming a hollow portion (S1) and connecting the precast panel 100 up and down, and acts in the horizontal and vertical directions. It serves as a reinforcing material to ensure bending rigidity against loads (horizontal and vertical loads), and in particular, the H-type steel members 131 are formed in a lattice shape to increase manufacturing efficiency.

Accordingly, referring to FIGS. 2A, 2B, 2C, and 2D, the precast panel 100 of the present invention includes a reinforced concrete panel body 110, a hollow finishing plate 120, and a lattice-type steel structure 130. Includes.

First, the reinforced concrete panel body 110 is a panel structure made of reinforced concrete, as shown in FIGS. 2C and 2B, and functions as the body of the precast panel 100. Inside this reinforced concrete panel body 110, the reinforcing bar assembly 111 is set to secure a covering thickness near both surfaces of the reinforced concrete panel body 110.

Accordingly, referring to FIGS. 2C and 2D, between the reinforcing bar assemblies 111, a lattice steel structure is provided in which a hollow part finishing plate 120 is fixedly installed around the hollow part S1 to maintain the hollow part S1, which is an empty space. Since (130) is set, the hollow portion (S1) is naturally formed by the lattice-type steel structure 130 to play a role in reducing self-weight.

This reinforced concrete panel body 110 is set by lowering and inserting the lifted reinforcing bar assembly 111 and the lattice-type steel structure 130 into the vertical mold with a plurality of vertical mold steel forms installed adjacent to each other. After that, the concrete is poured into the steel form to produce it, and after demolding, it is lifted and stacked vertically in large quantities. It is also mounted vertically on a vehicle and brought to the site, and it is also lifted vertically and moved up and down and left and right. Connection will be installed.

It is desirable to install the reinforcing bar assembly 111 by arranging a multi-layered reinforcing bar network such as wire mesh rather than arranging the reinforcing bars individually, so as to overcome difficulties in arranging the reinforcing bars.

In addition, referring to FIGS. 3A, 3B, and 3C, the manufactured precast panels 100 are vertically connected by stacking them horizontally using the upper and lower connectors 114 or the panel upper and lower connectors 132, and are connected and installed on the left and right. The connection is installed horizontally using a lateral connector (115).

The top and bottom connectors 114 use H-type steel, etc. to ensure constructability, the panel top and bottom connectors 132 use H-type steel extending from the grid-type steel structure 130, and the lateral connectors 115 You can use square pipes and H-shaped steel materials that make up the lattice steel structure 130, or manufacture and use reinforcing bar assemblies for connections.

In addition, referring to Figures 2c and 2d, a socket connection part (S2) is formed at the left and right connection parts (ends on both sides) of the reinforced concrete panel body 110, and this socket connection part (S2) is a precast panel. (100) That is, it is for connecting the left and right sides of the reinforced concrete panel body 110.

This socket connection portion (S2) is an empty space formed by excluding concrete pouring between the connection flanges (112) over the entire height (H) on both sides of the reinforced concrete panel body portion (110).

Accordingly, referring to FIG. 3C, the connection flanges 112 of the reinforced concrete panel body portion 110 adjacent to each other on the left and right are in contact with each other and the socket connection portion S2 is connected to each other, and the lateral connection member (S2) is connected to the connected socket connection portion S2. 115) is inserted,

The lateral connector 115 is located approximately at the center of the area where the connection flanges 112 are in contact with each other, and the socket connector S2 is filled with a filler 113 containing non-shrink mortar to form a reinforced concrete panel body 110. ) makes integration possible.

Next, the hollow part finishing plate 120 is installed to maintain the hollow part (S1), which is an empty space formed by the lattice steel structure 130 of the precast panel 100, as shown in FIGS. 2C and 2D. It acts as a finishing material.

Normally, precast panels do not form a hollow part (S1) as an empty space, but are finished by inserting, for example, EPS blocks. Since these EPS blocks have a smaller specific gravity than concrete, the concrete for the reinforced concrete panel body 110 is placed vertically. Since buoyancy is generated when pouring inside a molded steel form, it is inconvenient to fix the installation location. In particular, EPS blocks are somewhat expensive, so they may affect the economic feasibility of manufacturing the precast panel (100). It becomes possible.

Accordingly, the present invention maintains the hollow portion (S1) as an empty space and installs a hollow portion finishing plate (120) as a finishing plate to prevent concrete from penetrating into the interior.

That is, referring to FIGS. 2A and 2B, the H-shaped steel members 131 constituting the lattice steel structure 130 are arranged to be perpendicular to each other at regular intervals, so that a hollow portion S1 is naturally formed.

Accordingly, the hollow part (S1) is an empty space, so that the self-weight of the precast panel can be reduced, and a hollow part finishing plate (120) in the form of a horizontal plate (121) is installed around the hollow part (S1) so that the hollow part (S1) is not exposed. It is fixed to the surface of the grid-type steel structure 130 using a structural adhesive.

It is desirable that this hollow part finishing plate 120 is manufactured from a concrete plate and is made of the same material as the reinforced concrete panel body 110 to ensure material integrity.

In addition, referring to FIGS. 2C and 2D, the hollow part finishing plate 120 has its abdomen exposed on the bottom and top of the H-shaped steel member 131 constituting the lattice steel structure 130, so that the U-shaped plate 122 ) can be used to further expand the hollow portion (S1).

Next, the lattice steel structure 130 is embedded in the body of the precast panel 100, as shown in FIGS. 2A and 2B, so that a hollow portion (S1) is formed inside the reinforced concrete panel body 110. It plays a role in ensuring bending rigidity that can resist the applied load, and also serves to connect the top and bottom of the precast panel 100.

This lattice steel structure 130, as shown in FIGS. 2A and 2B, is formed by installing H-type steel members 131 so that they intersect each other on the same plane in the horizontal and vertical directions in the form of a square lattice, and is a precast panel. It extends to the upper and lower surfaces of (100), and is used to vertically connect the adjacent precast panel 100 and the base plate 200 using the panel upper and lower connectors 132.

The reason for using the H-type steel member 131 at this time is that a ready-made product can be used as is, so the lattice-shaped steel structure 130 can be manufactured by cutting it to the required length with little processing required, setting it in a lattice shape, and integrating it by welding, etc. Because there is.

Since the H-type steel member 131 does not occupy space except for both flanges and the abdomen, even when used as a lattice steel structure 130, the bending rigidity in the horizontal and vertical directions is increased rather than the self-weight of the precast panel 100. Since the effect is greater, it can play a role in minimizing the thickness of the precast panel 100.

That is, the flanges of the H-shaped steel members 131 are brought into contact with each other to form a lattice shape, so that the hollow part S1 is naturally formed. According to FIGS. 2A and 2B, the H-shaped module manufactured as one module is lateralized. They can be connected to each other to secure a certain horizontal length, making it possible to efficiently respond to the size of the precast panel 100, and are formed to be embedded in the reinforced concrete panel body 110 of the precast panel 100.

In addition, in order to integrate the H-type steel member 131 with the reinforced concrete panel body 110, a plurality of shear connectors 133 including studs are formed,

Referring to FIG. 3C, the shear connector 133 is connected to the reinforcing bar assembly 111, so that the lattice steel structure 130 and the reinforcing bar assembly 111 of the reinforced concrete panel body 110 are connected to each other and integrated (composite). This allows it to resist the load.

Accordingly, the reinforcing bar assembly 111 is located on the surface of the precast panel 100 to reinforce the areas where the lattice steel structure 130 is not formed, and the lattice steel structure 130 is in the form of a grid in the horizontal and vertical directions, In other words, it can be seen that it is possible to resist loads acting in two directions (horizontal and vertical loads), thereby effectively resisting the load acting on the precast panel 100.

In the case of FIG. 2A, in the H-shaped steel member 131 formed in the square grid shape, panel upper and lower connecting members 132 can be additionally formed to connect the upper and lower sides of the precast panel 100 and the base plate 200. You can see that there is.

Referring to FIGS. 2A and 2B, these panel upper and lower connectors 132 are formed in a grid shape and are formed on the bottom and top surfaces of the H-shaped steel member 131 to extend downward and upward at a certain length on the same plane,

A square pipe (132a) is used as the panel top and bottom connector 132 for upper and lower connection of the precast panel 100, and a square pipe (132a) or H-type steel connector (132b) is used for connection to the base plate 200. You can see that it's happening.

When the square pipe (132a) is used as the panel upper and lower connector 132, constructability is greatly improved because connection is possible by inserting the upper and lower connector 114 into the square pipe 132a, and the H-type steel connector 132b is used. If so, it can be connected by inserting into the insertion groove 210 formed on the upper surface of the base plate 200 using the same material as the H-shaped steel member 131 formed in a grid shape.

This H-type steel connector (132b) is

Accordingly, in the case of FIG. 2A, it can be seen that a case in which a square pipe 132a is used at the upper part and an H-type steel frame connector 132b is used as the panel upper and lower connecting member 132 is disclosed.

At this time, the lower H-shaped steel connector 132b extends further from the bottom of the reinforced concrete panel body 110 and is exposed to the outside, and the upper square pipe 132a is aligned with the upper surface of the reinforced concrete panel body 110. It can be seen that it is extended to form and the inside is exposed.

Next, in the case of FIG. 2B, it can be seen that an example of using the upper square pipe 132a and the lower square pipe 132a as the panel upper and lower connecting members 132 is shown. Accordingly, it can be seen that the upper and lower square pipes 132a are extended so that the upper surface is formed in line with the upper and lower surfaces of the reinforced concrete panel body 110 and the interior is exposed.

[Up and down and left and right connection of the precast panel 100 of the present invention]

Figures 3a, 3b and 3c show examples of the top and bottom and left and right connections of the precast panel 100 of the present invention.

The upper and lower connection of the precast panel 100 is carried out vertically and brought into the site, and then stacked in the vertical direction by lifting it as is, rather than standing it vertically (lifting and installing a horizontally set one). By connecting and installing them, constructability is secured.

At this time, in the case of Figure 3a, the precast panel 100 uses a square pipe 132a at the top and an H-type steel frame connector 132b at the bottom as the panel upper and lower connectors 132 used for vertical connection, and in Figure 3b. In this case, the precast panel 100 is a panel top and bottom connector 132 used for vertical connection, and the upper and lower square pipes 132a and the top and bottom connector 114 are additionally used to form a precast panel on the upper surface of the base plate 200. (100) can be considered an example of laminated construction.

Accordingly, looking at the case where the upper part is a square pipe 132a and the lower part is an H-type steel connector 132b as the panel upper and lower connector 132 used to connect the precast panels 100 to each other, based on FIG. 3A, the following is shown. same.

As shown in Figure 3a, the panel upper and lower connectors 132 formed on the bottom of the precast panel 100 are formed of H-type steel connectors 132b extending outward, and these H-type steel connectors 132b are connected to the base plate ( It can be seen that they are connected to each other by being inserted into the insertion groove 210 of 200).

Accordingly, the insertion groove 210 is a groove extending downward to a certain depth on the upper surface of the base plate 200, and the inside is filled with a filler, and the H-type steel connector 132b is inserted, and when the filler is cured, it is simply freed. The cast panel 100 can be integrated into the base plate 200.

Accordingly, since the upper surface of the insertion groove 210 is left in a finished state, factors that interfere with the work flow, such as conventional connecting reinforcing bars, are eliminated when workers step on them or lift and install the precast panel 100 with a crane, etc. can do.

Accordingly, in the process of vertically connecting and installing the precast panel 100 on the base plate 200, the finish is removed and the work is performed.

Next, as shown in Figure 3a, it can be seen that the panel upper and lower connectors 132 formed on the upper surface of the precast panel 100 are square pipes 132a, and the precast panel to be connected from the top to the inside of the square pipes 132a filled with filler (100) After the H-shaped steel connector 132b extending from the bottom is inserted and the filler is cured, the precast panel 100 can be simply connected up and down.

Next, the case where the precast panel 100 uses square pipes 132a and top and bottom connectors 114 at the top and bottom as panel top and bottom connectors 132 used for vertical connection is as follows based on FIG. 3B.

First, as shown in Figure 3b, the panel upper and lower connectors 132 formed on the bottom of the precast panel 100 are formed of square pipes 132a that do not extend to the outside, and these square pipes 132a are connected using the upper and lower connectors 114. It is connected to the insertion groove 210 of the base plate 200, and the upper and lower connecting members 114 can be seen that, for example, an H-type steel member is used.

Accordingly, the insertion groove 210 is also a groove extending downward at a certain depth on the upper surface of the base plate 200, and the inside is filled with a filler, and the lower part of the H-shaped steel member, which is the upper and lower connecting member 114, is inserted, and then the filler is inserted. Once cured, the precast panel 100 can be easily integrated into the base plate 200. In addition, the upper part of the H-shaped steel member, which is the upper and lower connecting member 114, is inserted into the square pipe 132a exposed on the bottom of the precast panel 100.

Next, in the case of FIG. 3B, it can be seen that the panel upper and lower connecting members 132 formed on the upper surface of the precast panel 100 are also square pipes 132a.

Accordingly, after inserting the lower and upper parts of the H-shaped steel member, which is the upper and lower connecting member 114, into the upper and lower square pipes 132a, respectively, once the filler is cured, the precast panel 100 can be simply connected up and down.

At this time, in order to ensure that the upper and lower connecting members 114 are inserted into the square tubes 132a of the grid-type steel structure 130, it is desirable to further form connecting steel locking holes in the form of horizontal plates, etc., inside the square tubes.

As a result, the upper and lower connections of the precast panel 100 can be stacked at a desired height using the exposed upper and lower connecting members 114 of the lattice-type steel structure 130, and the upper surface of the lattice-type steel structure 130 in contact with the top and bottom It is desirable to install water-expandable water-stop materials on the upper and lower surfaces so that water-tightness can be secured as the water-stop materials are compressed by the self-weight of the precast panel 100 located at the top.

Next, the left and right connections of the precast panel 100 are performed by transporting the precast panel 100 in the vertical direction and bringing it into the site, as shown in FIG. 3C, and then using the socket connection portion (S2) and the lateral connection member ( 115) is used.

That is, when the end surfaces of the connection flanges 112 of the precast panels 100 adjacent to each other on the left and right are brought into contact with each other, the socket connection portion S2 naturally communicates to the inside by the connection flange 112.

Accordingly, the lateral connector 115 is lowered and inserted into the socket connection part S2, and the inside of the socket connection part S2 is filled with a filler 113 so that the lateral connector 115 is embedded, thereby ensuring sufficient resistance to horizontal shear force. It is desirable to use assembled square pipes as the lateral connecting members 115 to ensure convenience in manufacturing.

In order to integrate the filler inside the socket connection part (S2), it is desirable to give the inner side of the connection flange 112 of the socket connection part (S2) a rough finish to ensure composite performance, and the lateral connector 115 is used for connection. Reinforcing bar assemblies can be used, and it is okay to use H-type steel members.

At this time, when using a reinforcing bar assembly for connection as the lateral connector 115, referring to FIG. 4, concrete is poured inside the reinforcing bar assembly for integration and integrated, and between the outer side where the concrete is poured inward and the socket connection portion (S) It can be seen that the amount of filler 113 used is reduced by injecting the filler 113.

Figure 4 shows another embodiment of the left and right connection of the precast panel 100.

According to FIG. 4, it can be seen that the pillar precast panel 300 can be additionally used as another example of connecting the left and right sides of the precast panel 100.

In other words, even if the precast panels 100 are installed vertically and horizontally, due to the wall structure of the building structure, there will be cases where the precast panels 100 must be installed in a direction perpendicular to the extension direction. For this, precast panels on the pillars are installed. (300) is used.

Accordingly, the pillar precast panel 300 can be formed in a cross shape, ㄱ shape, or ㅓ shape as shown in Figure 4, and in common, the lateral connection flange 320 is formed integrally with each other on the side of the central body 310. You can see that they are trying to do it.

In this case, the central body 310 is a pillar member and is filled with filler 113 so that the panel upper and lower connectors 132 and 114 are embedded vertically inside it, like the precast panel 100. Can be installed vertically connected.

Accordingly, the central body portion 310 is formed in a square cross-sectional shape, but a socket connection portion (S2) is also formed by the lateral connection flange 320, and precast structures are connected to each other using the socket connection portion (S2). It can be seen that the panel 100 can be connected left and right by changing the direction.

For this purpose, the lateral connector 115 is also used in the communicating socket connection portion S2, so that the left and right connections between the precast panel 100 and the column precast panel 300 are the same.

[Manufacturing and construction method of precast panel 100 of the present invention]

Figures 5a and 5b show a flow chart of the construction method of the precast panel 100 of the present invention.

The construction method of the precast panel 100 is to first construct the base plate 200, and then precast in one stage using, for example, top and bottom connectors 114 and lateral connectors 115 on the upper surface of the base plate 200. The panels 100 are connected up, down, left, and right, and according to the shape of the structure, the precast panels 100 are connected left and right using pillar precast panels 300, and the precast panels 100 are connected in two or more stages. It can be said to be a method of connecting up and down and left and right.

At this time, the architectural structure (A) includes architectural structures such as warehouses, sewage treatment plants, wastewater treatment plants, multi-story factory structures, etc., but naturally includes structures such as floor plates without using the pillar precast panel 300. In the present invention, architectural structures such as multi-storey warehouses and multi-story factory structures are examined.

In this building structure, the precast panels 100 are connected up and down and left and right to form vertical walls and floor plates on the base plate 200, and are adjusted to the shape using pillar precast panels 300.

5A and 5B are based on the case where the insertion groove 210 formed in the base plate 200 and the panel upper and lower connector 132 extending from the bottom of the precast panel 100 are used in combination.

Accordingly, as shown in Figure 5a, the base plate 200 is constructed first.

The base plate 200 can be constructed by excavating the ground, placing foundation reinforcement, and then pouring concrete to a certain thickness.

After installing a box (a type of mold, not shown) so that the insertion groove 210 can be formed in advance, dismantle it so that the insertion groove 210 is formed at a certain depth. If it is covered with a finishing plate, foreign substances, etc. It does not flow in, and unlike connecting rebar, it does not interfere with work flow.

Accordingly, the insertion groove 210 is formed at a position corresponding to the position of the panel upper and lower connecting members 132 of the precast panel 100 and the column precast panel 300.

Accordingly, the precast panel 100, which has been manufactured in advance at a factory, is manufactured, mounted on a vehicle in its open state, and brought to the site.

Next, as shown in Figure 5a, the insertion groove 210 of the base plate 200 is filled with a filler, and then the upper part of the panel upper and lower connecting material exposed on the bottom of the precast panel 100 lifted by a crane, etc. 132) is inserted to connect and install the first stage of precast panels 100 up and down.

In other words, since the precast panel 100 brought into the site is set by lifting it at both ends using lifting hooks and stacking it on the upper surface of the base plate 200, work such as making it stand up on site is necessary. won't do it.

At this time, according to the shape of the building structure, a single precast panel (100) is installed by vertically connecting it to the base plate (200) using the pillar precast panel (300), and the pillar precast panel (300) is It can be used in areas where the extension direction of the precast panel 100 is to be changed.

Next, the first-stage construction is completed by connecting and installing in the left and right directions using the lateral connectors 115 shown in FIG. 4.

The lateral connector 115 can be used when installing one precast panel 100 in one stage and connecting and installing other precast panels 100 laterally.

This left and right connection is made by inserting the lateral connector 115 into the socket connection portion (S2) formed by contacting the end surface of the connection flange 112 of the precast panel 100, and filling the socket connection portion (S2) with a filler to form the lateral connector ( 115) is buried, and as we have seen, a reinforcing bar assembly for connection can be used as the lateral connector 115.

Next, as shown in FIG. 5b, the wall structure of the building structure is constructed at a certain height by connecting other precast panels 100 up and down and left and right on the upper surface of the first stage precast panel 100, and the space between the wall structures is constructed as shown in FIG. 5b. The floor plate is connected to complete the multi-layered building structure (A).
