Description

Precast member connection device and precast structure manufacturing method using the same {CONNECTION APPARATUS FOR PRECAST MEMBER AND PRECAST STRUCTURE PREFABRICATING MRTHOD}

The present invention relates to a precast member connecting device and a precast structure construction method using the same. More specifically, it relates to a precast member connecting device that can quickly connect and integrate concrete column members, beam members, and wall members manufactured using the precast method in the field, and a method of manufacturing a precast structure using the same.

Figure 1a shows an example of connecting and combining pillars, crossbeams, and vertical parts of a conventional wooden house.

A beam connecting pillar (10) formed by processing a log so that the vertical hole (11) and the horizontal hole (13) communicate with each other; A horizontal beam 20 having coupling portions 21 formed at both ends to be inserted into the horizontal hole 13; A plurality of vertical beams (30) are inserted into the vertical holes (11) and have coupling portions (31) formed at both ends to be coupled to the coupling portions of the cross beam (20);

A gap member 40 fitted into 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 coupled to the horizontal hole and the vertical hole in an interference fit manner to prevent the coupling portion of the horizontal beam and the vertical beam from being separated arbitrarily.

Accordingly, the coupling parts 21 and 31 inserted into the horizontal hole and the vertical hole are connected by crossing each other and are coupled using the wedge member 50.

In cases such as logs that are easy to process, there is no great difficulty in forming these horizontal holes 11 and vertical holes 13.

When manufacturing columns, crossbeams, and vertical beams made of concrete, the cost of processing horizontal and vertical holes and the bonding performance when using wedge members are not high, so in the case of large structures, it is limited to use wood connection and joining methods such as logs. There will be.

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

That is, a tip (T), a groove (G), and a chin (C) are formed in advance on the upper part of the corner pillar 61, and a tip (T) corresponding to the tip (T), groove (G), and chin (C) is formed in advance. , the corner column 61 and the first and second direction beams 62 and 63 are assembled and installed by inserting and installing the first and second direction beams (61 and 63) formed with grooves (G) and ledges (C). It's a method.

This is because it is assumed that the corner pillar 61 and the first and second direction beams 62 and 63 are manufactured in the form of a steel tube that is easy to form the tip (T), groove (G), and chin (C), There are also limits to its application to columns, crossbeams, and stringers made of concrete.

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

The PC structure is a connecting means for connecting column members and beam members manufactured by precast method to each other,

After installing the connected PC members that extend upward and have a longitudinal receiving groove 71 formed on the outer peripheral surface, one side of the connecting piece 72 as a bracket is inserted into the longitudinal receiving groove 71 so that the other side is horizontal in the longitudinal direction. causing it to protrude from the receiving groove (71); and

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

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

The strengthening is done by allowing the internal connecting reinforcing bar 74, which extends to the notch portion formed at the top or bottom of the end surface of the beam 73, and both the top and bottom, to penetrate the synthetic anchorage block 75 and fix it with a fastener to form the composite anchorage block 75. ) is fixed in position,

One side of the insert connecting rebar (77) is fastened to the insert (76) formed at the top and bottom of the longitudinal receiving groove (71) formed in the PC member, and the other side penetrates the synthetic anchoring block (75) and anchored with a fastener to synthesize the product. It can be seen that the internal connecting reinforcing bar 74 and the insert connecting reinforcing bar 77 are crossed and anchored in the anchoring block 75.

In other words, it is possible to construct the PC structure by assembling and connecting the pre-fabricated pillar member 78 and the beam 73 to each other, but this is a connection piece that is a bracket installed on the pillar member in the longitudinal insertion hole 71 formed in the beam. (72) Because it is necessary to go through a complex process of inserting the connecting reinforcement bars by crossing each other, a large number of column member and beam connection parts are inevitably formed, resulting in too many repetitive works, resulting in construction costs. There was a problem with this excessive consumption.

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

The precast member connecting device 100 of the present invention is a precast member connecting device 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). Let us examine it separately into Example 1 and Example 2 according to (100).

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

Figures 2a, 2b and 2c show an example of a precast member connecting device 100 for connecting and integrating the pillar member A1 and the 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 the beam member A2 according to Example 1 includes a vertical connecting plate 110, as shown in FIGS. 2A, 2B, and 2C, It includes a vertical groove 120 and a filler 130.

First, referring to Figure 2c, the pillar member (A1) is a vertically extended member manufactured by precasting, and grid-shaped vertical grooves 120 are formed in advance on the upper surface, and sleeves and pull-out bars are shown at the top and bottom. However, the installation height can be adjusted using bolt fasteners, etc., and a stopping block (A11) that communicates integrally with the vertical groove (120) is installed on the upper side so that the end surface of the beam member (A2) can be seated. It can be seen that more can be formed.

In addition, referring to FIG. 2C, the beam member A2 is a horizontally extending member manufactured by precasting and is formed at both ends so that the horizontal exposed portion 111 of the vertical connecting plate 110 is exposed, and the upper surface A slab deck, etc., not shown, may be installed.

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

That is, the embedded part 112 in the form of a vertical plate is embedded inside the end of the beam member A2, and the horizontal exposed part 111, which extends from the embedded part 112 and is smaller in height than the embedded part 112, is exposed to the outside. By exposing it, it can be seen that it is made easy to insert and install by descending from the top downward into the grid-like vertical groove 120 of the pillar member A1, as shown in FIG. 2b.

The vertical connecting plate 110 formed of the horizontal exposed portion 111 and the embedded portion 112 may be formed by using a vertical plate as shown in the left drawing of FIG. 2A or having a T-shaped cross section that is advantageous for securing connection rigidity as shown in the right drawing of FIG. 2A. It can be seen that it is possible to use members, and although not shown, H cross-section members, etc. can also be used.

Accordingly, 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 pillar member A1.

That is, the exposed horizontal exposed portions 111 of the vertical connecting plate 110 are aligned, for example, in a direction orthogonal to each other in the first direction (transverse direction), that is, in the second direction (vertical direction), with respect to the pillar member A1. It can be seen that they are connected so as to overlap in the grid-shaped vertical grooves 120,

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

That is, as shown in Figure 2b, the horizontal exposed portion 111 in the second direction (vertical direction) is located above the horizontal exposed portion 111 in the first direction (transverse direction), so that the image in the vertical groove 120 is, It can be seen that they are arranged downward and do not interfere with each other and are connected by overlapping each other in the grid-shaped vertical grooves 120. Accordingly, the horizontal exposed portion 111 in the first direction (transverse direction) is L-shaped and the second It can be seen that the horizontal exposed portion 111 in the direction (vertical direction) is set in an L shape.

Also, referring to FIGS. 2B and 2C, it can be seen that a shear connector 114 is further installed on the horizontal exposed portion 111 to be integrated with the filler 130 filled in the vertical groove 120.

At this time, the vertical grooves 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 corners of the precast structure (A), that is, the pillar member (A1) ) It is natural that the vertical groove 120 can be formed only in the first or second direction, respectively, depending on the installation location.

As a result, the beam member A2, which must be connected to the pillar member A1 as shown in Figure 2c, is lowered from above into the vertical grooves 120 in the form of a grid, for example, formed on the upper surface of the pillar member A1 so that they overlap without interfering with each other. You can connect,

The vertical connecting plates 110 in the first direction (transverse direction) and the second direction (vertical direction) are connected so as to overlap each other horizontally, and are positioned upward and downward and are inserted into the grid-shaped vertical grooves 120 to insert the filler 130. ), it can be seen that it is being integrated.

In addition, the horizontal exposed portions 111 of the vertical connection plates 110 in the first direction (horizontal direction) and the second direction (vertical direction), which are set to overlap each other, can be fixed to each other using bolts, welding, etc.

Next, the vertical groove 120 is a groove formed at a certain depth on the upper surface of the pillar member A1, as shown in FIG. 2C, and is vertical in the first direction (transverse direction) and the second direction (vertical direction). The horizontal exposed portions 111 constituting the connecting plate 110 are inserted downward and are formed to have a width and thickness just enough to cross each other.

It is natural that these vertical grooves 120 may be formed in a straight shape rather than a grid shape depending on the installation position of the pillar member A1.

Since these vertical grooves 120 are formed with a width and thickness sufficient to allow the horizontal exposed portions 111 of the vertical connecting plate 110 to be inserted downward and intersect with each other, the cross-sectional loss of the column member A1 can be minimized. Also, it is advantageous to ensure that the horizontal exposed portion 111 is confined within the vertical groove 120.

As shown in FIG. 2C, the filler 130 is inserted into the vertical groove 120 formed in the pillar member A1 by inserting the horizontal exposed portion 111 of the beam member A2 so that the beam member A2 is connected to the pillar member A1. It is a means to integrate while connected to.

In this connected state, the horizontal exposed portion 111 of the pillar member A1 in the vertical groove 120 is integrated with each other by the filler 130, and eventually, the pillar member A1 and the beam member A2 are strengthened and integrated with each other. do.

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

Figures 3c, 3d and 3f show an example of a precast member connecting device 100 for connecting and integrating the pillar member A1 and the beam member A2 according to Example 2 of the present invention.

The precast member connecting device 100 according to Example 2 has a difference in the shape of the horizontal exposed portion 111 constituting the vertical connecting plate 110 of the beam member A2 compared to Example 1, and as a result, Unlike Example 1, the horizontal exposed portions 111 are connected in the first direction (horizontal direction) and the second direction (vertical direction) even if the horizontal exposed portions 111 are not disposed above and below the vertical groove 120. Differences arise when it becomes possible.

Accordingly, the precast member connecting device 100 for connecting and integrating the column member A1 and the beam member A2 according to Example 2 is a vertical connecting plate 110, as shown in FIGS. 3A, 3B, and 3C. , vertical groove 120, and filler 130 are the same as in Example 1.

That is, referring to FIG. 3C, the column member A1 is a vertically extended member manufactured by precasting and has grid-shaped vertical grooves 120 formed in advance on its upper surface, and a sleeve and a pull-out reinforcing bar are also shown. However, the installation height can be adjusted using bolt fasteners, etc., and a stopping block (A11) integrally communicating with the vertical groove (120) is added to the upper side so that the end surface of the beam member (A2) can be seated. What can be formed is the same.

In addition, referring to FIG. 3C, the beam member A2 is a horizontally extending member manufactured by precasting and is formed at both ends so that the horizontal exposed portion 111 of the vertical connecting plate 110 is exposed, and the upper surface A slab deck, etc., not shown, may be installed.

Next, referring to FIG. 3A, it can be seen that the vertical connecting plate 110 is formed by embedding a steel material at the end of the beam member A2 so that the horizontal exposed portion 111 is exposed to the outside. In Example 2, the horizontal exposed portion 111 is exposed to the outside. It differs from Example 1 in that the end of the portion 111 is formed to be bent.

That is, the embedded portion 112 in the form of a vertical plate is embedded inside the end of the beam member A2, and the horizontal exposed portion ( It can be seen that 111) is exposed to the outside, making it easy to insert and install by descending downward from the top into the grid-like vertical groove 120 of the pillar member A1, as shown in FIG. 3B.

It can be seen that the vertical connecting plate 110 formed of the horizontal exposed portion 111 and the buried portion 112 with bent ends is used as a vertical plate as shown in FIG. 3A.

Accordingly, 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 pillar member A1.

That is, the horizontal exposed portion 111, in which the exposed end of the vertical connecting plate 110 is bent, moves in a direction orthogonal to each other in addition to the first direction (horizontal direction), that is, in the second direction (vertical direction), for example, with respect to the pillar member A1. It can be seen that the direction (direction) is the same as the fact that they are connected so as to overlap in the vertical grooves 120 in the form of a grid.

For example, the horizontal exposed portions 111, whose ends are bent in the first direction (transverse direction) and the second direction (vertically), are bent at their ends in the first direction (transverse direction) so that they do not interfere with each other inside the vertical groove 120. It can be seen that the gum portion 111a of the horizontal exposed portion 111 is arranged so that the end in the second direction (vertical direction) is in contact with the extension portion 111b of the bent horizontal exposed portion 111.

That is, unlike Example 1, the horizontal exposed portion 111 with the end bent in the first direction (horizontal direction) as shown in FIG. 3b is the horizontal exposed portion 111 with the end bent in the second direction (vertical direction). It can be seen that they are arranged on horizontal extension lines in the vertical grooves 120 and are connected by overlapping each other in the grid-shaped vertical grooves 120 without interfering with each other.

In addition, in the case of Example 2, unlike Example 1, a shear connector is not shown in the horizontal exposed portion 111 so as to be integrated by the filler 130 filled in the vertical groove 120, but it is natural that it can be installed.

At this time, the vertical grooves 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 corners of the precast structure (A), that is, the pillar member (A1) ) is the same as Example 1 in that the vertical groove 120 can be formed only in the first or second direction, respectively, depending on the installation location.

As a result, as shown in Figure 3b, the beam member A2, which must be connected in all directions with respect to the pillar member A1, is lowered from above into the vertical grooves 120 in the form of a grid, for example, formed on the upper surface of the pillar member A1, so that they do not interfere with each other. It can be connected to overlap,

The vertical connecting plates 110 in the first direction (transverse direction) and the second direction (vertical direction) are connected so as to overlap each other horizontally, and are positioned upward and downward and are inserted into the grid-shaped vertical grooves 120 to insert the filler 130. ) It can be seen that the integration is the same as Example 1.

Also, the vertical connecting plates 110 of the vertical groove 120 can be fixed to each other using fixtures including bolts or welding.

Next, the vertical groove 120 is a groove formed at a certain depth on the upper surface of the pillar member A1, as shown in FIG. 3C, and is vertical in the first direction (transverse direction) and the second direction (vertical direction). The horizontal exposed portions 111 constituting the connecting plate 110 are inserted downward and formed to a width and thickness just large enough to cross each other, in the same manner as in Example 1.

It is natural that these vertical grooves 120 may be formed in a straight shape rather than a grid shape depending on the installation position of the pillar member A1.

Since these vertical grooves 120 are formed with a width and thickness sufficient to allow the horizontal exposed portions 111 of the vertical connecting plate 110 to be inserted downward and intersect with each other, the cross-sectional loss of the column member A1 can be minimized. Also, it is advantageous to ensure that the horizontal exposed portion 111 is confined within the vertical groove 120.

As shown in FIG. 3C, the filler 130 is inserted into the vertical groove 120 formed in the pillar member A1 by inserting the horizontal exposed portion 111 of the beam member A2 so that the beam member A2 is connected to the pillar member A1. It is a means to integrate while connected to.

In this connected state, the horizontal exposed portion 111 of the pillar member A1 in the vertical groove 120 is integrated with each other by the filler 130, and eventually, the pillar member A1 and the beam member A2 are strengthened and integrated with each other. do.

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

The precast member connecting device 100 for connecting and integrating the column member (A1) and the wall member (A3) connects and integrates the column member (A1) and the beam member (A2) with each other or connects the beam member (A2). And regardless of the whole, a wall member ( A3) is installed, and the filler 130 is filled in the side vertical groove 150 where the enlarged head connection member 140 is accommodated to ensure connection and integration.

Accordingly, referring to FIG. 4A, the enlarged head connecting member 140 has a wall sleeve 141 embedded in the side of the pillar member A1 in advance so that the entrance is exposed to the side of the pillar member A1, and the exposed Fasten the enlarged head connecting rebar (142) to the wall sleeve (141) and set it so that the enlarged head is pulled out horizontally,

Next, referring to FIG. 4A, the side vertical groove 150 is a vertical groove formed on the connection side to accommodate the enlarged head connecting reinforcing bar 142 exposed on the side of the column member A1.

For this purpose, according to FIG. 5b, if, for example, a U-shaped channel member is embedded in the connection side and the inside is exposed, the enlarged head connecting reinforcing bar 142 is naturally accommodated in the exposed space (S).

In particular, when the enlarged head connecting reinforcing bar 142 is used, the anchorage length is reduced by the enlarged head, so it is possible to optimize the cross-sectional loss of the wall member A3 due to the side vertical groove 150. .

This wall member (A3) is installed by stacking it up and down. According to Figure 4b, connection steel and steel insertion grooves are formed on the upper and lower surfaces of the wall member (A3) to correspond, respectively, so that the wall members (A3) are stacked up and down ( A3) is able to integrate the top and bottom with each other by injecting the filler 130 into the steel insertion groove.
