Description

{CONNECTION APPARATUS FOR PRECAST MEMBER AND PRECAST STRUCTURE PREFABRICATING METHOD}

The present invention relates to a precast member connecting device and a method for manufacturing a precast structure using the same. More specifically, the present invention relates to a precast member connecting device capable of rapidly connecting column members, beam members, and wall members made of concrete manufactured by the precast method on site to manufacture them as one unit, and a method for manufacturing a precast structure using the same.

Figure 1a illustrates an example of the connection and joining of columns, crossbeams, and vertical sections of a conventional wooden house.

A beam connecting column (10) formed by processing a log so that a vertical hole (11) and a horizontal hole (13) are connected to each other; a horizontal beam (20) having a connecting portion (21) formed at both ends to be inserted into the horizontal hole (13); a plurality of vertical beams (30) having a connecting portion (31) formed at both ends to be inserted into the vertical hole (11) and connected to the connecting portion of the horizontal beam (20);

A gap member (40) fitted between the vertical gap between the crossbeams and the vertical gap between the vertical beams; and

It can be seen that a wedge member (50) is introduced that is forcibly joined in the horizontal hole and the vertical hole to prevent the joining portion of the above-mentioned crossbeam and the joining portion of the above-mentioned vertical beam from being separated arbitrarily.

Accordingly, the connecting parts (21, 31) inserted into the horizontal hole and the vertical hole are connected by crossing each other and are connected using a wedge member (50).

In the case of easy processing such as logs, there is no great difficulty in forming these horizontal holes (13) and vertical holes (11).

When manufacturing columns, crossbeams, and vertical beams made of concrete, the cost of processing crossholes and vertical holes and the low bonding performance when using wedge members make it difficult to use log-like wood connection and joining methods for large structures.

Figure 1b is an example of a connection and joining method between a conventional steel column member and a beam.

That is, a method of assembling and installing the corner pillar (61) and the first and second direction beams (62, 63) by forming a tip (T), a groove (G), and a protrusion (C) in advance on the upper part of the corner pillar (61) and then inserting and installing the first and second direction beams (62, 63) having a tip (T), a groove (G), and a protrusion (C) corresponding to the tip (T), the groove (G), and the protrusion (C).

Since this is based on the premise that it is manufactured in the form of a steel tube that is easy to form a tuck (T), a groove (G), and a protrusion (C) on the corner column (61) and the first and second direction beams (62, 63), there are limitations in applying it to columns, crossbeams, and vertical beams manufactured from concrete.

Figure 1c illustrates an example of a connection construction diagram of a conventional PC structure.

The above PC structure is a connecting means for connecting column members and beam members manufactured in a precast manner.

A step of installing a PC member that extends upward and has a longitudinal receiving groove (71) formed on the outer surface, and then inserting one side of a connecting piece (72) as a bracket into the longitudinal receiving groove (71) so that the other side protrudes horizontally from the longitudinal receiving groove (71); and

(b) a step of lifting a beam (73) having a longitudinal insertion hole (71) formed with an open bottom so that it can be inserted downward into the connecting piece (72), and connecting the beam (73) between PC members in a hinged state by inserting the other side of the connecting piece (72) into the longitudinal insertion hole (71);

After the above step (b), the PC member and beam (73) are strengthened,

The above-mentioned reinforcement is fixed by fixing the synthetic fixing block (75) by allowing the internal connecting reinforcing bar (74) extended through the notch formed at the top or bottom of the end face of the beam (73) to penetrate the synthetic fixing block (75) and fixing it as a fastening hole, thereby fixing the synthetic fixing block (75) in position.

It can be seen that one side of the insert connecting reinforcing bar (77) is fastened to the insert (76) formed at the upper and lower portions of the longitudinal receiving groove (71) formed in the PC member, and the other side penetrates the synthetic fixing block (75) to be fixed as a fastening hole, so that the internal connecting reinforcing bar (74) and the insert connecting reinforcing bar (77) are fixed by crossing each other in the synthetic fixing block (75).

That is, although the PC structure can be constructed by assembling and connecting pre-fabricated column members (78) and beams (73), this requires a complicated process of inserting a connecting piece (72), which is a bracket installed on the column member, into a longitudinal insertion hole (71) formed in the beam, and ultimately connecting connecting reinforcing bars by crossing each other. As a result, multiple connection points between the column member and the beam are inevitably formed, which results in too many repetitive processes, and thus there is a problem in that construction costs are excessively high.

Accordingly, the present invention aims to provide a precast structure connecting device and a precast structure manufacturing method using the same, which enables faster and more economical construction by simply lifting and vertically lowering and inserting the column members and beam members without using connecting reinforcing bars or brackets, unlike in the past, in constructing a PC structure by manufacturing column members, beam members, and wall members using a precast concrete manufacturing method and connecting and integrating them with each other.

In addition, the technical task to be solved is to provide a precast structure connecting device and a method of manufacturing a precast structure using the same, which enable faster and more economical construction by connecting and integrating column members and wall members by simply lifting the wall member to the side of the column member and inserting it vertically downward.

In order to achieve the above object, the precast member connecting device of the present invention comprises: two beam members (A2) each having a vertical connecting plate embedded in the end portion thereof so that the horizontally exposed portion is exposed to the outside; and a column member (A1) having a vertical groove formed on the upper surface thereof only with a width and thickness such that the horizontally exposed portions can be lowered and inserted to intersect each other; The horizontally exposed portions of the two vertical connecting plates are connected by overlapping each other in the vertical groove, and the vertical connecting plate is formed by embedding the horizontally exposed portion in the end portion of the beam member (A2) so that the horizontally exposed portion is exposed to the outside, and the embedded portion is embedded in the beam member (A2), and the horizontally exposed portion extended from the embedded portion is exposed so that it can be lowered and inserted into the vertical groove of the column member (A1) and installed. The vertical connecting plates of the vertical groove are fixed to each other by a fastener including a bolt or welding.

In addition, a method for manufacturing a precast structure using a precast member connecting device for achieving the above task includes (a) a step of connecting and integrating a column member (A1) and a beam member (A2) using the precast member connecting device in such a way that a vertical connecting plate of a beam member (A2) is lowered and inserted into a vertical groove of the column member (A1) after constructing the column member (A1); and (b) a step of also integrating a wall member (A3) between the side surfaces of the column member (A1) in such a way that they are lowered and inserted; wherein the precast member connecting device of step (a) includes: two beam members (A2) each having a vertical connecting plate embedded in an end portion so that a horizontal exposure portion is exposed to the outside; And it includes a pillar member (A1) having a vertical groove formed on the upper surface only with a width and thickness such that the horizontal exposure portions can be inserted downwardly and intersect each other, and the horizontal exposure portions of the two vertical connecting plates are connected so as to overlap each other in the vertical groove, and the vertical connecting plate is formed by embedding the horizontal exposure portion in the end of the beam member (A2) so that it is exposed to the outside, so that the embedding portion is embedded in the beam member (A2), and the horizontal exposure portion extended from the embedding portion is exposed so that it can be inserted downwardly into the vertical groove of the pillar member (A1) and installed, and the vertical connecting plates of the vertical groove are fixed to each other by a fixing member including a bolt or welding.

According to the present invention, in the case of a precast structure connecting device, a vertical connecting plate made of, for example, steel is formed at the end of a beam member so that the horizontal portion thereof is exposed, a vertical groove is formed on the upper surface of a column member, and the horizontal portion of the vertical connecting plate exposed at the end of the beam member is lowered and inserted, and the vertical groove is closed, thereby connecting and integrating the column member and the beam member with each other. Therefore, it is possible to provide a precast member connecting device that is faster, ensures sufficient integration, and has excellent constructability and workability, and a method for manufacturing a precast structure using the same.

In addition, according to the present invention, a vertical channel for receiving enlarged head bolts formed in a plurality on the side of a column member is formed on the connecting side of a wall member, and the wall member is also lifted and lowered, and then the wall member is set on the side of the column member, and then the vertical channel is filled with filler to simply connect and integrate it, so that it is possible to provide a precast member connecting device that is quicker and ensures sufficient integration while also having excellent constructability and workability, and a method for manufacturing a precast structure using the same.

[ Precast member connecting device (100) of the present invention ]

The precast member connecting device (100) of the present invention will be examined by dividing it into Embodiment 1 and Embodiment 2 by the precast member connecting device (100) for connecting and integrating a column member (A1) and a beam member (A2) and connecting and integrating a column member (A1) and a wall member (A3).

[Precast member connecting device (100) for connecting and integrating beam member (A2) according to Example 1]

FIG. 2a, FIG. 2b and FIG. 2c illustrate examples of a precast member connecting device (100) for connecting and integrating a column member (A1) and a beam member (A2) according to Example 1 of the present invention.

The precast member connecting device (100) for connecting and integrating the column member (A1) and beam member (A2) according to the above embodiment 1 includes a vertical connecting plate (110), a vertical groove (120), and a filler (130), as shown in FIGS. 2a, 2b, and 2c.

First, the column member (A1), as shown in Fig. 2c, is a vertically extended member manufactured in a precast manner, with a grid-shaped vertical groove (120) formed in advance on the upper surface, and although upper and lower sleeves and draw-out reinforcing bars are shown, it can be seen that the installation height can be adjusted mutually by using bolt fastening holes, etc., and a catch block (A11) integrally connected to the vertical groove (120) can be further formed on the upper side so that the end face of the beam member (A2) can be secured.

In addition, referring to Fig. 2c, the beam member (A2) is formed as a horizontally extended member manufactured in a precast manner so that the horizontally exposed portion (111) of the vertical connecting plate (110) is exposed at both ends, and a deck for a slab (not shown) can be installed on the upper surface.

Next, referring to Fig. 2a, it can be seen that the vertical connecting plate (110) is formed by embedding a horizontal exposed portion (111) of steel material into the end of the beam member (A2) so that it is exposed to the outside.

That is, it can be seen that the vertical plate-shaped embedded portion (112) is embedded inside the end of the beam member (A2), and the horizontal exposed portion (111) that extends from the embedded portion (112) and has a smaller height than the embedded portion (112) is exposed to the outside, so that it can be easily inserted and installed by lowering it from above into the grid-shaped vertical groove (120) of the column member (A1) as shown in Fig. 2b.

It can be seen that the vertical connecting plate (110) formed by the horizontal exposure portion (111) and the embedded portion (112) can use a vertical plate as shown in the left drawing of Fig. 2a, or a T-shaped cross-section member that is advantageous in securing connection rigidity as shown in the right drawing of Fig. 2a, and although not shown, an H-shaped cross-section member or the like can also be used.

Referring to FIG. 2b, it can be seen how the vertical connecting plate (110) of the beam member (A2) is inserted into the vertical groove (120) of the column member (A1).

That is, it can be seen that the exposed horizontal exposure portion (111) of the vertical connecting plate (110) is connected to overlap in a grid-shaped vertical groove (120) in a second direction (vertical direction) that is orthogonal to the first direction (horizontal direction) with respect to the column member (A1), for example.

It can be seen that the horizontal exposure portions (111) in the first direction (horizontal direction) and the second direction (vertical direction) do not interfere with each other inside the vertical groove (120), for example, the horizontal exposure portion (111) in the second direction (vertical direction) is arranged above the horizontal exposure portion (111) in the first direction (horizontal direction).

That is, as shown in Fig. 2b, the horizontal exposure portion (111) in the second direction (vertical direction) is positioned higher than the horizontal exposure portion (111) in the first direction (horizontal direction) so that they are arranged vertically in the vertical groove (120) so as not to interfere with each other and overlap each other in the grid-shaped vertical groove (120), and thus it can be seen that the horizontal exposure portion (111) in the first direction (horizontal direction) is set in an L-shape, and the horizontal exposure portion (111) in the second direction (vertical direction) is set in an L-shape.

Also, referring to FIGS. 2b and 2c, it can be seen that a shear connecting member (114) is further installed in the horizontal exposure portion (111) so as to be integrated by the filling material (130) filled in the vertical groove (120).

At this time, the vertical groove (120) may be formed in a grid shape so that the first direction (horizontal direction) and the second direction (vertical direction) are perpendicular to each other, and at the corner portion of the precast structure (A), that is, depending on the installation position of the column member (A1), it is natural that the vertical groove (120) may be formed only in the first direction or the second direction.

In this way, the beam member (A2) that should be connected based on the column member (A1) as shown in Fig. 2c can be connected by lowering from above into a vertical groove (120) formed, for example, in a grid shape, on the upper surface of the column member (A1) so that they overlap without interfering with each other.

It can be seen that the vertical connecting plates (110) in the first direction (horizontal direction) and the second direction (vertical direction) are connected so as to overlap each other horizontally, but are positioned upward and downward and inserted into a grid-shaped vertical groove (120) and integrated by a filler (130).

In addition, the horizontally exposed portions (111) of the first direction (horizontal direction) and second direction (vertical direction) vertical connecting plates (110) set to overlap each other can be fixed to each other by means of bolts, welding, etc.

Next, the vertical groove (120) is first formed as a groove with a constant depth formed on the upper surface of the pillar member (A1) as shown in Fig. 2c, and is formed with a width and thickness just enough to allow the horizontal exposure portions (111) constituting the vertical connecting plates (110) in the first direction (horizontal direction) and the second direction (vertical direction) to be inserted downward and intersect with each other.

It goes without saying that these vertical grooves (120) may be formed in a straight line rather than a grid shape depending on the installation location of the pillar member (A1).

Since these vertical grooves (120) are formed with a width and thickness that allow the horizontally exposed portions (111) of the vertical connecting plates (110) to be lowered and intersect each other, the cross-sectional loss of the column member (A1) can be minimized, and it is also advantageous to ensure that the horizontally exposed portions (111) are confined within the vertical grooves (120).

The above-mentioned filler (130) is a means for integrating the beam member (A2) with the column member (A1) by inserting the horizontally exposed portion (111) of the beam member (A2) into the vertical groove (120) formed in the column member (A1), as shown in Fig. 2c.

In this connection state, the horizontal exposure portion (111) of the column member (A1) in the vertical groove (120) is integrated with each other by the filler (130), and ultimately, the column member (A1) and the beam member (A2) are rigidly connected to each other and integrated.

[Precast member connecting device (100) for connecting and integrating beam member (A2) according to Example 2]

FIG. 3c, FIG. 3d and FIG. 3f illustrate examples of a precast member connecting device (100) for connecting and integrating a column member (A1) and a beam member (A2) according to Example 2 of the present invention.

The precast member connecting device (100) according to the above embodiment 2 has a difference in the shape of the horizontal exposure portion (111) constituting the vertical connecting plate (110) of the beam member (A2) compared to embodiment 1, and thus, unlike embodiment 1, the horizontal exposure portion (111) is not arranged in the vertical groove (120) upward and downward, but the connection of the horizontal exposure portion (111) in the first direction (horizontal direction) and the second direction (vertical direction) is possible, which causes a difference.

Accordingly, the precast member connecting device (100) for connecting and integrating the column member (A1) and beam member (A2) according to the above embodiment 2 is the same as that of embodiment 1 in that it includes a vertical connecting plate (110), a vertical groove (120), and a filler (130), as shown in FIGS. 3a, 3b, and 3c.

That is, the column member (A1), as shown in Fig. 3c, is a vertically extended member manufactured in a precast manner, with a grid-shaped vertical groove (120) formed in advance on the upper surface, and although a sleeve and a draw-out reinforcing bar are also illustrated, the installation height can be adjusted to each other using a bolt fastening hole, etc., and a catch block (A11) that is integrally connected to the vertical groove (120) so that the end face of the beam member (A2) can be secured can be additionally formed on the upper side surface.

In addition, referring to Fig. 3c, the beam member (A2) is formed as a horizontally extended member manufactured in a precast manner so that the horizontally exposed portion (111) of the vertical connecting plate (110) is exposed at both ends, and a deck for a slab (not shown) can be installed on the upper surface.

Next, it can be seen that the vertical connecting plate (110) is formed by embedding a horizontal exposed portion (111) in the end of the beam member (A2) with steel material so that it is exposed to the outside, referring to Fig. 3a. In the case of Example 2, there is a difference from Example 1 in that the end of the horizontal exposed portion (111) is formed to be bent.

That is, it can be seen that the vertical plate-shaped embedded portion (112) is embedded inside the end of the beam member (A2), and the horizontal exposed portion (111) that extends from the embedded portion (112), has the same height as the embedded portion (112), and has a bent end is exposed to the outside, so that it can be easily inserted and installed by lowering it from above into the grid-shaped vertical groove (120) of the column member (A1) as shown in FIG. 3b.

It can be seen that the vertical connecting plate (110) formed by the horizontal exposed portion (111) and the buried portion (112) with the short section is using a vertical plate as shown in Fig. 3a.

Referring to FIG. 3b, it can be seen how the vertical connecting plate (110) of the beam member (A2) is inserted into the vertical groove (120) of the column member (A1).

That is, it can be seen that the exposed end of the vertical connecting plate (110) is connected so that the horizontally exposed portion (111) is folded and overlaps in the grid-shaped vertical groove (120) in the second direction (vertical direction) that is perpendicular to the first direction (horizontal direction) with respect to the column member (A1), for example.

It can be seen that the horizontal exposure portions (111) whose ends are bent in the first direction (horizontal direction) and the second direction (vertical direction) do not interfere with each other inside the vertical groove (120), for example, the gum portion (111a) of the horizontal exposure portion (111) whose end is bent in the first direction (horizontal direction) is arranged to be in contact with the extension portion (111b) of the horizontal exposure portion (111) whose end is bent in the second direction (vertical direction).

That is, unlike Example 1, it can be seen that the horizontal exposure portion (111) with the end portion in the first direction (horizontal direction) folded as shown in Fig. 3b is connected to the horizontal exposure portion (111) with the end portion in the second direction (vertical direction) folded by being arranged on a horizontal extension line in the vertical groove (120) so as not to interfere with each other and to overlap each other in the grid-shaped vertical groove (120).

In addition, in the case of Example 2, unlike Example 1, the shear connecting material is not shown in the horizontal exposure portion (111) so that it can be integrated by the filling material (130) filled in the vertical groove (120), but it is of course possible to install it.

At this time, the vertical groove (120) may be formed in a grid shape so that the first direction (horizontal direction) and the second direction (vertical direction) are perpendicular to each other, and at the corner portion of the precast structure (A), that is, depending on the installation position of the column member (A1), the vertical groove (120) may be formed only in the first direction or the second direction, which is the same as in Example 1.

In this way, the beam member (A2) that must be connected in all directions based on the column member (A1) as shown in Fig. 3b can be connected by lowering from above into a vertical groove (120) formed on the upper surface of the column member (A1) in the form of a grid, for example, so that they overlap without interfering with each other.

It can be seen that the vertical connecting plates (110) in the first direction (horizontal direction) and the second direction (vertical direction) are connected so as to overlap each other horizontally, but are positioned upward and downward and inserted into vertical grooves (120) in a grid shape and are integrated by filler (130), which is the same as in Example 1.

Likewise, the vertical connecting plate (110) of the vertical groove (120) can be fixedly installed to each other by a fixing member including a bolt or welding.

Next, the vertical groove (120) is first formed as a groove with a constant depth formed on the upper surface of the pillar member (A1) as shown in Fig. 3c, and is formed with a width and thickness that are just enough to allow the horizontal exposure portions (111) constituting the vertical connecting plates (110) in the first direction (horizontal direction) and the second direction (vertical direction) to be lowered and intersect each other, which is the same as in Example 1.

It goes without saying that these vertical grooves (120) can be formed in a straight line rather than a grid shape depending on the installation location of the pillar member (A1).

Since these vertical grooves (120) are formed with a width and thickness that allow the horizontally exposed portions (111) of the vertical connecting plates (110) to be lowered and intersect each other, the cross-sectional loss of the column member (A1) can be minimized, and it is also advantageous to ensure that the horizontally exposed portions (111) are confined within the vertical grooves (120).

The above-mentioned filler (130) is a means for integrating the beam member (A2) with the column member (A1) by inserting the horizontally exposed portion (111) of the beam member (A2) into the vertical groove (120) formed in the column member (A1), as shown in Fig. 3c.

In this connection state, the horizontal exposure portion (111) of the column member (A1) in the vertical groove (120) is integrated with each other by the filler (130), and ultimately, the column member (A1) and the beam member (A2) are rigidly connected to each other and integrated.

Next, the precast member connecting device (100) for connecting and integrating the column member (A1) and the wall member (A3) in the precast structure (A) includes an enlarged head connecting member (140) and a side vertical groove (150), as shown in FIGS. 4a and 4b.

A precast member connecting device (100) for connecting and integrating a column member (A1) and a wall member (A3) is configured to expose an enlarged head connecting member (140) on the side surface of the column member (A1), install a wall member (A3) having a side vertical groove (150) formed on the connecting side surface in which the enlarged head connecting member (140) is received, and fill a filler (130) into the side vertical groove (150) in which the enlarged head connecting member (140) is received, so that the column member (A1) and the beam member (A2) are connected and integrated, regardless of whether the column member (A1) and the beam member (A2) are connected and integrated.

Accordingly, referring to Fig. 4a, the enlarged head connecting member (140) is set by pre-embedding a wall sleeve (141) in the side of the column member (A1) so that the entrance is exposed on the side of the column member (A1), and the enlarged head connecting reinforcing bar (142) is fastened to the exposed wall sleeve (141) at the site so that the enlarged head is pulled out horizontally.

Next, the side vertical groove (150) is a vertical groove formed on the connecting side to accommodate the expanded head connecting reinforcing bar (142) exposed on the side of the column member (A1), as shown in FIG. 4a.

To this end, as shown in Fig. 5b, if a channel member in the shape of the letter “ㄷ” is embedded in the connecting side and the inside is exposed, the expanded head connecting reinforcing bar (142) is naturally accommodated in the exposed space (S).

In particular, when the above-mentioned enlarged head connecting reinforcing bar (142) is used, the fixing length is reduced by the enlarged head portion, so that the cross-sectional loss of the wall member (A3) due to the side vertical groove (150) can be minimized.

These wall members (A3) are installed by stacking them up and down. According to Fig. 4b, connecting steel and steel insertion grooves are formed to correspond to each other on the upper and lower surfaces of the wall members (A3), so that the wall members (A3) stacked up and down can be integrated with each other by injecting filler (130) into the steel insertion grooves.

[Method for manufacturing a precast structure (A) using a precast member connecting device (100) of the present invention]

Figures 5a and 5b illustrate a flow chart of a method for manufacturing a precast structure (A) using a precast member connecting device (100) of the present invention.

The method for manufacturing a precast structure (A) using the above precast member connecting device (100) can be said to be a method for constructing a precast structure (A) including a cooling tower using the precast member connecting device (100) for connecting and integrating the column member (A1) and the beam member (A2) and connecting and integrating the column member (A1) and the wall member (A3) as discussed above.

Referring to FIG. 5a, first, the column member (A1) is constructed, and then the vertical connecting plate (110) of the beam member (A2) is lowered and inserted into the vertical groove (120) of the column member (A1) to connect and integrate the column member (A1) and the beam member (A2), and then the wall member (A3) is lowered and inserted between the side surfaces of the column member (A1) to integrate them as well.

The above pillar members (A1) are manufactured in a factory, transported to the site, and installed at a distance from each other by lifting them using a lifting device. They are installed by standing them up on the floor plate of the precast structure (A). This can be done by using connecting means such as sleeves and draw-out reinforcing bars.

These pillar members (A1) can be installed by connecting multiple ones vertically based on the installation height, and this can also be done by using connecting means such as sleeves and draw-out reinforcing bars.

These pillar members (A1) have a vertical groove (120) formed on the upper surface, and an enlarged head connecting member (140) formed on the side so that a wall sleeve (141) is exposed on the side.

Accordingly, as shown in FIGS. 2 and 3, the vertical connecting plate (110) is lowered and inserted into the vertical groove (120), and the vertical connecting plate (110) is inserted into the vertical groove (120) in the first and second directions, and then connected and integrated with each other using the filler (130).

In addition, as shown in FIGS. 4a and 4b, the wall member (A3) exposes an enlarged head connecting member (140) on the side of the column member (A1), and a wall member (A3) having a side vertical groove (150) formed on the connection side in which the enlarged head connecting member (140) is accommodated is installed, and a filler (130) is filled in the side vertical groove (150) in which the enlarged head connecting member (140) is accommodated, so as to be connected and integrated.

Referring to FIGS. 5a and 5b, it can be seen that the beam member (A2) is installed on the constructed column member (A1), beam member (A2), and wall member (A3).
