Description

Continuation device for overlapping reinforcement of precast wall and its construction method {APPARATUS FOR REINFORCED BAR OVERLAY OF PRECAST WALL AND ITS CONSTRUCTION METHOD THEREOF}

The present invention relates to an apparatus for continuous reinforcement of a precast wall and a construction method thereof. More specifically, in the lateral continuous construction of the precast wall, the connection reinforcing bar is set in an overlapping reinforcing bar structure, and then the device for continuous overlapping reinforcement of the precast wall and its construction method to enable structural continuity using an injection material It is a technical task to solve the provision of construction methods.

Conventional underground continuous walls (underground continuous walls) block the inflow of groundwater, trench the ground to a predetermined depth by using a bucket or trench cutter designed suitable for soil excavation, and then supply a stabilizer in proportion to the excavated soil volume. It is constructed in a way that prevents the collapse of the excavation surface, inserts a reinforced net into the trench, and repeats the operation of pouring concrete to form a continuous reinforced concrete wall in the ground.

1A is a diagram showing a construction example of a conventional underground continuous wall.

That is, a first underground continuous wall (W1) of a certain length is constructed, the second underground continuous wall (W2) is constructed by being spaced apart by the connection portion (22), and the connection portion (22) is installed with an excavator (bucket or trench cutter). ) After excavation, injecting a stabilizer solution to connect the first underground continuous wall (W1) and the second underground continuous wall (W2) to the connection part, and construct the connection part underground continuous wall (W3) to be integrated. You can see that there is.

1B is a diagram illustrating an exemplary continuous construction of a conventional underground continuous wall.

That is, in the conventional continuation and integration of adjacent underground continuous walls, the end horizontal roots (5: 5a, 5b) drawn out from the end plate (3) of the preceding underground continuous wall (1) and the end level of the subsequent underground continuous wall (2). After setting the reinforcing bars (8) and reinforcing bars (11) so that they overlap each other in the trench at the connection part, concrete for the subsequent underground continuous wall (2) was poured, and it was found that the adjacent underground continuous walls were continuously constructed by rebar connection. I can.

Accordingly, it is possible to secure the longitudinal integrity of the underground continuous wall by constructing the end horizontal bars (8) and the reinforcing bars (11) to overlap each other, but in construction, the end finish plate of the preceding underground continuous wall (1) (3) Under the condition that the reinforcing bar is exposed to the connection part, trench excavation at the connection part is made, a stabilizing solution is injected into the connection part trench, and the reinforcing bar of the exposed preceding underground continuous wall (1) is continued underground. Due to the need to construct such that the reinforcing bars by the end plate 3 of the wall 2 overlap each other, there is a limit in which the workability and workability are deteriorated due to a large amount of space-time interference between the reinforcing bars.

Figure 1c shows an example of the construction of the overlapping reinforcement of the conventional underground continuous wall.

It can be seen that the connecting reinforcing bars of the underground continuous wall to be continuous are arranged as overlapping reinforcing bars, and a binding reinforcing bar 13 is used while installing vertical reinforcing bars 18 to bind the overlapping reinforcing bars to each other.

In addition, it can be seen that the steel connecting hardware 12 is used together to make the connecting reinforcement continuous while securing the rigidity of the connecting portion.

However, the underground continuous walls of FIGS. 1A to 1C are all wet methods in which concrete is poured into the ground to construct the underground continuous walls with reinforced concrete, and in the method of inserting the underground continuous walls in a precast method, which is a dry method, this method Is difficult to use.

In relation to this, according to the recent domestic “building seismic design standard (KSD 41 17 00)”, in the case of an underground continuous wall, it is possible to safely behave against the bending moment acting in the extension direction (longitudinal direction) of the underground continuous wall. It stipulates that the underground continuous wall should be continuous with joints (couplers, welding, etc.) and reinforcing bars.

In other words, in the conventional underground continuous wall, the underground continuous wall constructed by being spaced apart from each other is continuously and integrated. How to connect the adjacent underground continuous wall connection between the first and the next underground continuous wall connection. It can be seen that it is a very important question whether to meet the “building seismic design standard (KSD 41 17 00)”.

Accordingly, the present invention forms a side connection space (S) capable of injecting an injection material into a connection part formed on the side of the precast wall in the continuous construction of the precast wall (dry type) after excavation of the ground. Even if it is not possible to set the connection reinforcement in the side connection space (S) with an overlapping reinforcing bar structure, it is possible to simplify structural continuity, while securing workability and enabling rapid construction of precast wall overlapping reinforcing bars. And it is a technical task to solve the provision of the construction method.

[Apparatus 100 for continuing overlapping reinforcing bars of precast wall of the present invention]

2A, 2B, 2C, and 2D show a perspective view and an installation example of the apparatus 100 for continuing overlapping reinforcement of a precast wall of the present invention.

The apparatus 100 for continuing the overlapping reinforcement of the precast wall according to the present invention is shown in Figs. 2A and 2C, and the connection reinforcing bar 210 formed on the side of the precast wall 200 is first set and interferes with the side. It is to solve the problem that it is difficult to form an overlapping reinforcement structure with the connection reinforcement 210 of the precast wall 200 to be connected and constructed.

That is, as shown in FIGS. 2C and 2D, in a state in which the upper and lower connecting reinforcing bars 210 protrude from the upper and lower surfaces of the precast wall 200, the connecting reinforcing bars formed on the sides of the precast wall 200 are overlapped. It is impossible to construct with the upper and lower connecting reinforcements (see FIGS. 2C and 2D) because they interfere with each other.

Accordingly, the present invention is set so that the connection reinforcement 210 of the precast wall 200 must be connected to the connection reinforcing bar 210 of the precast wall 200 that was first constructed, referring to FIGS. 2B, 2C and 2D. It is characterized in that the connection reinforcing bars 210 of the precast wall 200 can be simply constructed in an overlapping reinforcing bar structure by rotating the apparatus 100 for continuing the overlapping reinforcing bars of the precast wall.

Accordingly, the apparatus 100 for continuing overlapping reinforcing bars of the precast wall includes a vertical insert 110, a horizontal rotation connector 120, a lower support part 130, and a vertical stiffener as shown in FIGS. 2A, 2B, 2C and 2D. 140).

First, the vertical insert 110 may use a deformed reinforcing bar having a constant diameter as a vertical bar member, as shown in FIGS. 2A, 2B, 2C, and 2D, and preferably, the precast wall 200 It is preferable to use the same reinforcement as the connection reinforcement 210.

This vertical insert 110 is between the connection reinforcement 210 that do not overlap each other in the side connection space (S) that is naturally formed in the process of construction so that the sides of the adjacent precast wall 200 are continuous with each other, referring to FIG. 2B. After inserting the horizontal rotation connector 120 into the, it serves as a support rod having a rotation support point for rotation.

In other words, it is installed so that the lower end is supported on the bottom (G) of the side connection space (S) of the precast wall 200 to form a rotational support point, so that the integrated horizontal rotation connector 120 rotates horizontally. Is done.

Accordingly, the vertical insert 110 is formed to extend over the entire height of the side connection space (S), and since it is a vertical bar member, it is easy to insert into the side connection space (S), and when using a deformed reinforcement, it is easy to process. Therefore, economical use becomes possible.

In addition, it is possible to install the extended height by connecting a plurality of vertical inserts 110 to each other.

On the outer circumferential surface of the vertical insert 110, as shown in FIG. 2A, a horizontal rotation connector 120, which will be described later, is horizontally spaced apart from each other and integrated.

Accordingly, when the vertical insert 110 is rotated while the lower end of the vertical insert 110 is supported on the bottom G of the side connection space S, the horizontal rotating connector 120 spread in a horizontal plane can also be rotated. There will be.

Next, the horizontal rotation connector 120 is formed integrally with the outer peripheral surface of the vertical insert 110 horizontally, as shown in Figs. 2a, 2b, 2c and 2d, while rotating together with the vertical insert 110, adjacent The connection reinforcement 210 of the precast wall 200 is positioned between the upper and lower portions of the precast wall 200 so that the connection reinforcement 210 is formed in an overlapping reinforcement structure.

That is, in a state in which the precast walls 200 are installed adjacent to each other, the connection reinforcing bar 210 is not formed in an overlapping reinforcing bar structure, but as shown in FIGS. 2B, 2C and 2D,

In a state in which the vertical insert 110 is disposed in the center of the connecting reinforcing bar 210 adjacent to each other, the horizontal rotating connector 120 integrated on the outer circumferential surface of the vertical insert 110 is arranged above and below the top of the connecting reinforcing bar 210, When inserted between the bottoms, naturally, both connecting reinforcing bars 210 and horizontal rotating connector 120 can be formed in an overlapping reinforcing bar structure by the effect of overlapping each other on a horizontal plane.

Accordingly, the horizontal rotation connector 120 must be rotated with the rotation of the vertical insert 110, and the vertical insert 110 has a function to be disposed in an overlapping reinforcing bar structure with the connection reinforcing bar 210. It is formed to be integrated and unfolded horizontally, and formed in the same horizontal arrangement shape as the horizontal arrangement shape of the connection reinforcing bar 210.

For example, referring to FIG. 2A, when the 8-shaped horizontal reinforcing bar center inner portion 121 is in contact with the outer circumferential surface of the vertical insert 110 and is integrated (possible by tag welding, etc.), both side portions 122 are central inner portions. Based on (121), it can be formed using reinforcing bars that are horizontally spread in a circle.

Accordingly, it is integrated with the vertical connector 132 and can be rotated together, and has a function of being inserted into rotation between the top and bottom of the connecting reinforcing bar 210 to form an overlapping reinforcing bar structure of the connecting reinforcing bar 210. It will be referred to as the connector 120.

Next, the lower support portion 130 is formed at the lower end of the vertical insert 110, as shown in Figs. 2a, 2b, 2c, and 2d, and acts as a rotational support point to enable the rotation of the horizontal rotation connector 120 It can also have a role that allows height adjustment while doing it.

That is, the vertical insert 110 is a vertical bar member, and when a certain length of reinforcing bar is used, the bottom is set so as to contact the bottom G of the side connection space S of the precast wall, but the bottom G may not be flat. In this case, it may affect the setting of the overlapping reinforcement structure by horizontal rotation.

Thus, according to FIG. 2A,

A support support 131 is formed at the lower end of the vertical insert 110, and a vertical connector 132 connected to the bottom surface of the vertical insert 110 is included in the outline center of the support support 131 to achieve flatness. While securing,

It can be seen that the vertical connector 132 can have no problem with the overlapping reinforcing bar structure by using a height adjustment sleeve 133 with a penetration depth adjusted at the bottom of the vertical insert 110,

It can be seen that the support support 131 and the vertical connector 132 serve as rotation support points so as not to be restricted from rotation to each other.

Further, according to FIG. 2A,

A bottom embedded anchor 134 is formed at the bottom of the vertical insert 110, and the top of the bottom embedded anchor 134 is accommodated in the inclined cone 135 formed on the bottom of the vertical insert 110

The upper end of the bottom-embedded anchor 134 is used as a rotation support point to facilitate the rotation of the vertical insert 110,

The floor-embedded anchor 134 may be installed in a manner such that it is pre-set together with the precast wall 200 in a state integrally pre-installed on the bottom of the precast wall 200.

Accordingly, the apparatus 100 for continuing overlapping reinforcing bars of the precast wall of the present invention can basically secure a function as a vertical insert 110 and a horizontal rotation connector 120, and the lower support 130 is complemented according to the construction site. Can be applied by means,

The structure is also simple, and in the case of manufacturing by processing reinforcing bars, it can be easily manufactured in the field, thus securing economy

If the bottom is supported on the bottom (G) of the side connection space (S), there is no fear of defects because it can be rotated regardless of the penetration depth.

When it is covered by the connecting reinforcing bar 210, it can be seen that the horizontal rotating connector 120 is disposed between the top and bottom of the connecting reinforcing bar 210, so quality control is also facilitated.

Next, the vertical stiffener 140 is, as shown in Figs. 2a, 2b, 2c, and 2d, when the connecting reinforcing bar 210 is formed of an overlapping reinforcing bar by rotating the horizontal rotating connector 120 As a reinforcing material inserted through the connection reinforcing bar 210 and the horizontal rotating connector 120 communicated downward, a reinforcing bar inserted vertically may be used.

Accordingly, the connection reinforcing bar 210, the vertical insert 110, and the horizontal rotation connector 120 are combined with each other by the injected injection material 230 to be integrated in the side connection space S, so that the precast wall 200 It plays a role in completing structural continuity.

Accordingly, the vertical stiffeners 140 may be individually inserted and are buried by the injection material 230.

[Construction method of the apparatus 100 for continuing overlapping reinforcement of the precast wall of the present invention]

Figure 3 shows a flow chart of the construction method of the continuous reinforcement reinforcement apparatus of the precast wall of the present invention.

The construction method of the apparatus 100 for continuing the overlapping reinforcing bars of the precast wall is, for example, a precast wall 200 installed adjacent to each other, but the connection reinforcing bars 210 are not overlapped with each other in the side connection space (S). As a method of forming an overlapping reinforcing bar structure with each other using the overlapping reinforcing bar continuous device 100 of the cast wall 200, it can be said that the final injection material 230 is injected into the side connection space S and integrated with each other. .

Accordingly, as shown in FIG. 3, the precast wall 200 is manufactured and brought into the site, and the precast wall 200 is erected and installed (S110).

The precast wall 200 is a reinforced concrete vertical wall having a certain height, and a connecting reinforcing bar 210 extending horizontally is installed in a plurality of vertically spaced up and down sides.

In addition, a connection flange 220 is formed on the side so that the side connection space S is formed so that the side connection space S is naturally formed inside the connection flange 220 so that the injection material 230 can be injected from the ground. .

Next, as shown in FIG. 3, the lower end of the apparatus 100 for reinforcing the overlapping reinforcement of the precast wall is supported on the floor of the side connection space S in the side connection space S formed by the precast walls 200 adjacent to each other. It will be installed as much as possible.

The apparatus 100 for continuing overlapping reinforcing bars of the precast wall is formed by a plurality of horizontal rotation connectors 120 on the outer circumferential surface of the vertical insert 110 and spaced apart from each other up and down.

Accordingly, when the lower end of the vertical insert 110 is installed to be supported on the bottom (G) of the side connection space (S), the connection reinforcement 210 formed adjacent to the side connection space (S) makes the overlapping reinforcement of the precast wall continuous. Since interference occurs in installing the device 100,

The horizontal rotating connector 120 and the connecting reinforcing bar 210 are inserted using the side connecting space S that is not occupied by the connecting reinforcing bar 210 so that they do not interfere with each other.

That is, by using the space (S2) not occupied by the connection reinforcing bar 210, the overlapping reinforcing bar continuous device 100 of the precast wall is inserted and installed downward in the side connection space (S).

Next, as shown in FIG. 3, the horizontal rotation connector 120 and the vertical insert 110 integrated with the horizontal rotation connector 120 of the precast wall overlapping reinforcement continuation device 100 are rotated in the same direction as the horizontal connection surface of the connection reinforcing bar 210 It is set to be formed into an overlapping reinforcing bar structure.

That is, by rotating the vertical insert 110 integrated with the horizontal rotation connector 120 of the precast wall overlapping reinforcement continuation device 100 in the space between the top and bottom of the connecting reinforcing bar 210, the connecting reinforcing bar 210 and The horizontal rotation connector 120 is set to overlap each other in a reinforcing bar structure.

The vertical insert 110 is a vertical rod member, and the lower end is formed as a rotation support point, so that it can be sufficiently rotated by manpower, etc., and horizontally by the connection reinforcement 210 when the side connection space (S) is visually viewed. If the rotating connector 120 is rotated so that it is not visible, it can be viewed as an overlapping reinforcing bar structure, so that the workability is excellent and quality control is easy.

Next, as shown in FIG. 3, the vertical stiffener 140 is lowered from the ground and inserted into the connection reinforcement 210 of the precast wall communicated up and down, and then the injection material 230 is injected into the side connection space (S). Thus, the connection reinforcing bar 210 and the apparatus 100 for continuing overlapping reinforcing bars of the precast wall are integrated with each other.

The injection material 230 may be made of non-shrinkable mortar, and the horizontal rotating connector 120 of the apparatus 100 for continuing the overlapping reinforcing bars of the precast wall is a vertical reinforcing material because it is in a state disposed between the top and bottom of the connecting reinforcing bar 210 It is possible to install (140) to penetrate the connecting reinforcing bar 210 and the horizontal rotating connector 120,

In this state, if the injection material 230 is injected from the top into the side connection space S, structural continuation of the precast wall can be achieved.

Accordingly, when a plurality of precast walls 200 are structurally integrated to the side and the side connection space (S) of the precast wall 200 is finished with the injection material 230, the head of the vertical insert 110 is finished (cutting, etc.) ) To complete the construction.

In the case of structurally continuous precast underground continuous walls with each other, when connecting reinforcing bars on the top and/or bottom are formed by extending upwards and downwards, connect the connecting rebars on the top and bottom of the precast underground continuous walls first. After that, when the connection reinforcement on the side of the precast underground continuous wall is constructed in an overlapping structure, the connection reinforcement on the side is inevitably interfered when the connection reinforcement on the upper and bottom surfaces is connected. It is also possible to use a stranded wire roof that can be deformed so that the reinforcing bar does not interfere. When using such a stranded wire roof, it has a characteristic that it stretches and cannot sufficiently exert a shear force, so that the structural performance is limited, so that the horizontal rotating connector 120 of the present invention has various shapes. It can be formed so that it is possible to sufficiently secure structural performance as an overlapping reinforcement structure.

The above description of the present invention is for illustrative purposes only, and those of ordinary skill in the art to which the present invention pertains will be able to understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. will be. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not limiting. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as being distributed may also be implemented in a combined form.
