Description

Rotary type overlapping reinforcing bar sequencing device and its construction method

The present invention relates to a rotary type stacked reinforcing bar sequencing device. More specifically, in sequentially constructing the precast wall laterally, in the side connection space (S) of the precast wall, the connecting reinforcing bars of the precast wall can be set in a stacked reinforcing bar structure while rotating independently during the lowering installation process. There is, it relates to a rotary type stacked reinforcing bar sequencing device capable of quickly and economically constructing an overlapping structure of a precast wall and a construction method thereof.

The conventional underground continuous wall (underground continuous wall) blocks the inflow of groundwater and trenches the ground to a predetermined depth designed by using a bucket or trench cutter designed for soil excavation, and then, in proportion to the excavated soil volume, supplying stabilizing liquid It is constructed in such a way that it prevents the trench excavation surface from collapsing, inserts a rebar mesh into the trench, and repeats the work of pouring concrete to form a continuous reinforced concrete wall in the ground.

Figure 1a shows a construction example of a conventional underground continuous wall.

That is, the first continuous underground wall (W1) of a certain length is constructed, the second continuous underground wall (W2) is constructed by being spaced apart by the connection portion 22, and the connection portion 22 is used with an excavator (bucket or trench cutter). ), and then injecting stabilizing liquid to connect the first continuous underground wall (W1) and the second continuous underground wall (W2) to the connecting portion and construct the continuous underground wall (W3) at the connection site to be integrated. It can be seen that there is, and it can be seen that this corresponds to the wet method of constructing the underground continuous wall with reinforced concrete by pouring concrete into the ground, not the precast method.

Figure 1b 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 serialized are installed as overlapping reinforcing bars, and the binding reinforcing bars 13 are also used while installing the 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 reinforcing bars continuous with each other while securing the rigidity of the connecting portion.

Accordingly, the continuous underground wall constructed underground in FIGS. 1A and 1B is a wet method in which the continuous underground wall is constructed with reinforced concrete by pouring concrete underground, and the continuous underground wall is inserted in a dry precast method. There is a limit in that it cannot be used in this way.

In relation to this, according to the recent domestic "Seismic Design Standards for Buildings (KSD 41 17 00)", in the case of a continuous underground wall (underground continuous wall), it is safe even for bending moments acting in the extension direction (longitudinal direction) of the continuous underground wall. It is stipulated that the underground continuous wall should be continuous with mechanical joints (couplers, welding, etc.) and reinforcing bar lap joints so that it can move.

In other words, the conventional continuous underground wall (underground continuous wall) is constructed to be continuous and integrated with the underground continuous wall constructed to be spaced apart from each other. It can be seen that the issue of how to serialize the "building earthquake-resistance design standards (KSD 41 17 00)" is becoming a very important issue.

Figure 1c shows an example of the construction of the overlapping reinforcement of the conventional outer wall (1,2).

The outer wall (1,2) is manufactured in the form of a vertical wall in an open space such as the ground, and the connecting reinforcing bars (3, 6) protrude horizontally from the connection side of the outer wall (1,2) at the cross-shaped connecting part. , After arranging the overlapping reinforcing bars (15:15a, 15b) separately at the cross-shaped connecting part, the outer wall (1,2) is moved horizontally to the connecting reinforcing bars (3, 6) and the overlapping reinforcing bars (15:15a, After 15b) overlap each other, the method of overlapping the connecting reinforcing bars 3 and 6, the overlapping reinforcing bars 15:15a, 15b and the vertical reinforcing bars 8 using the vertical reinforcing bars 8 is adopted. It can be seen that there is

Figure 1d shows an example of the construction of the precast wall 20 overlapping reinforcing bar structure constructed in the ground in the related art.

That is, even in a state in which the connecting reinforcing bars 21 located in the side connection space (S) of the precast wall 20 to be continuously constructed underground are not installed with each other as an overlapping reinforcing bar structure, the connecting reinforcing bars 21 with each other have an overlapping reinforcing bar structure. As an overlapping reinforcing bar sequencing device 30 of a precast wall so as to be formed as

A vertical insert 31 inserted from the top to the bottom in the side connection space (S) between the connecting reinforcing bars 21 that are not formed in an overlapping reinforcing bar structure; And while being integrally formed with the vertical insert 31 and rotating together with the vertical insert 31, it is located between the top and bottom of the connecting reinforcing bar 21 of the adjacent precast wall 20, the connecting reinforcing bar ( 21) and a horizontal rotation connecting member 32 to be formed into an overlapping reinforcement structure together with; an overlapping reinforcement sequencing device 30 for the precast wall 20 is introduced.

That is, in the side connection space (S) of the precast wall 20 installed so that the connecting reinforcing bars 21 are not formed in an overlapping reinforcing bar structure, the lower end of the vertical insert 31 is the bottom of the side connecting space (S) ( It is installed to be supported on G), and by rotating the vertical inserting member 31 integrated with the horizontal rotating connecting member 32, it is set in the same direction as the horizontal connecting surface of the connecting reinforcing bar 21 to form an overlapping reinforcing bar structure.

Accordingly, in the case of FIG. 1D, the overlapping reinforcing bar sequencing device 30 is a work of lowering and inserting and rotating the overlapping reinforcing bar sequencing device 30 using the upper working space into the side connection space (S) of the precast wall 20 installed first. ) has the advantage that it can be installed,

In order to vertically lower and insert the overlapping reinforcing bar sequencing device 30 into the side connection space (S), a certain amount of the side connection space (S) must be secured. There is a case in which the side connection space (S) of (20) is minimized, and in this case, there is a problem that the overlapping reinforcing bar sequencing device 30 as shown in FIG. 1d has limitations in use, such as having to adjust the size.

Republic of Korea Patent No. 10-2219326 (Title of the invention: device for sequencing overlapping reinforcing bars in precast walls and construction method thereof, publication date: February 23, 2021) Republic of Korea Patent No. 10-1037774 (Title of the invention: Connection structure for underground continuous wall construction and underground continuous wall construction method using the same, publication date: March 25, 2010) Japanese Patent Laid-Open Patent Application Laid-Open No. Hei 5-79105 (Title of the invention: method of joining precast concrete column walls, publication date: March 30, 1993)

Therefore, in the present invention, after excavating the ground, in constructing the precast wall serially, even if the size of the side connection space (S) of the precast wall is small and limited, it is self-reliant just by lowering and installing the overlapping reinforcing bar sequencing device. While the connecting reinforcing bars of the precast wall can be set in a stacked reinforcing bar structure, it is a technical task to solve the provision of a rotary type stacked reinforcing bar sequencing device and its construction method that can serialize the precast wall into a stacked reinforcing bar structure.

In addition, in the present invention, the precast wall can be set between the connecting reinforcing bars while the rotating overlapping material rotates independently just by lowering the overlapping reinforcing bar sequencing device to the side connection space (S) so that the tip is in contact with the floor (G). It is a technical task to solve the provision of a rotary type reinforcing bar sequencing device and its construction method that are economical to manufacture the reinforcing bar sequencing device because the structure of the rebar sequencing device is simple.

In addition, even if the size of the side connection space (S) is minimized, since the vertical lowering installation of the overlapping reinforcing bar sequencing device is possible, the amount of injection material injected into the side connection space (S) can be reduced, enabling more economical construction of rotating type overlapping reinforcing bars It is a technical task to solve the provision of the device and its construction method.

In order to achieve the above object, the rotary type overlapping reinforcing bar sequencing device and its construction method of the present invention include: a planar insert descending to the side connection space (S) of a precast wall; And a plurality of the flat inserts are installed so as to be rotatably spaced up and down to enable rotation, and the front end of the planar inserts in the side connection space (S) is lowered to be supported by touching the floor (G) of the side connection space (S). The planar insert, including; a rotating overlapping member that is folded upward while in contact with the reinforcing bars in turn, is formed to be rotated horizontally between the connecting reinforcing bars, and is lowered together in the side connection space (S) together with the planar inserts. The connecting reinforcing bars of the precast wall are formed in an overlapping reinforcing bar structure by simply lowering the rotating overlapping material formed so as to be able to rotate in the ash to the side connection space (S) of the precast wall.

According to the present invention, the connection reinforcing bar of the precast wall protrudes from the side connection space (S) formed at the connection part of the precast wall, and it interferes with the continuous construction, so even if it is impossible to initially set the reinforcing bar structure overlapping each other, the present invention By simply lowering the stacked reinforcing bar sequencing device, the connecting reinforcing bars can be simply set to the stacked reinforcing bar structure, making it possible to easily sequester the precast wall structure underground or above the ground.

In addition, according to the present invention, even if the side connection space (S) is minimized, the overlapping reinforcing bar sequencing device can be installed down to the side connection space (S), and only by making the tip of the overlapping rebar sequencing device contact the floor (G) As the rotating overlapping material rotates independently horizontally and can be set between the upper and lower connecting reinforcing bars, it is excellent in constructability and workability. Cast walls can be provided.

And in order to clearly explain the present invention in the drawings, parts irrelevant to the description are omitted, and similar reference numerals are attached to similar parts throughout the specification.

[Rotation type overlapping reinforcing bar sequencing device 100 of the present invention]

2a and 2b are diagrams illustrating the configuration and operation of the rotary stacking reinforcing bar sequencing device 100 of the present invention, and FIGS. 3a, 3b and 3c are installation examples of the rotary stacking reinforcing bar sequencing device 100 of the present invention will show

The rotary type overlapping reinforcing bar sequencing device 100 of the present invention interferes with the connecting reinforcing bars 210 formed on the side in a state in which the precast wall 200 is first set, and the precast wall 200 to be connected and constructed laterally. In order to solve the problem that it is difficult to form an overlapping reinforcing bar structure for the connecting reinforcing bars 210 of

Referring to FIGS. 2A and 2B , the rotational overlapping material 130 of the rotary overlapping reinforcing bar sequencing device 100 is lowered to the side connection space S while in contact with the connecting reinforcing bars 210 and rotates upward. As this is repeated, the rotating overlapping member 130 is installed horizontally (overlapping on the same plane as the connecting reinforcing bar 210) between the upper and lower connecting reinforcing bars 210.

That is, in the process in which the rotary type overlapping rebar sequencing device 100 is lowered to the side connection space (S), the rotary overlapping material 130 of the rotary type overlapping reinforcing bar sequencing device 100 comes into contact with the connecting reinforcing bars 210 in turn. While repeating the process of folding upward, when the rotary stacking reinforcing bar sequencing device 100 comes into contact with the final floor G, the rotary stacking member 130 is automatically set on the connecting reinforcing bar 210 to be horizontally finally set. .

To this end, the rotary type overlapping reinforcing bar sequencing device 100 includes a planar insert 110 , a rotary overlapping member 130 , and an insertion reinforcing material 150 as shown in FIGS. 2A and 2B .

First, as the planar insert 110, as shown in FIGS. 2A and 2B, as a vertical planar member, a tube member having a constant diameter, a deformed reinforcing bar, etc. may be used, and preferably, a tube member is used for easy handling by the operator. it is preferable

These planar inserts 110 are rotated between the upper and lower sides of the connecting reinforcing bars 210 formed without overlapping each other in the side connecting space (S) formed in the process of constructing the adjacent precast wall 200 sides to be continuous with each other. The overlapping member 130 serves as a support member to set the rotation horizontally (located on the same plane as the connecting reinforcing bar).

As shown in Fig. 2a, the planar insert 110 has both support parts 111 extending downward and both end connection parts 112 for connecting both ends of the support parts 111 to each other are integrally formed in a U-shaped closed closed shape. It can be seen that it can be formed of a vertical planar support member.

Accordingly, the operator can simply raise and lower the flat insert 110 over the entire height of the side connection space S by using the end connection part 112 on the ground, and the extension length is not long because it is a vertical planar support member. However, it is easy to transport and install.

In addition, the extended length may be installed while connecting a plurality of planar inserts 110 to each other.

It can be seen that a plurality of intermediate connecting members 113 are formed to be spaced apart from each other as shown in FIG. 2A between both support portions 111 of the planar insert 110 .

Accordingly, the end connection part 112 integrated with both the supporting parts 111 of the planar insert 110 is rotated so that it can be rotated on the intermediate connection member 113 while being supported on the floor G of the side connection space S. It can be seen that the ashes 130 are installed.

Next, as shown in FIGS. 2A and 2B , the rotating overlapping member 130 is connected to the planar insert 110 by a hinge (hook connection, etc.) to be rotatable, so that the side connection space of the precast wall (S) In this case, while the rotary reinforcing bar sequencing device 100 is repeatedly rotated during the lowering installation process, it serves to form the connecting reinforcing bars 210 of the precast wall in the stacked reinforcing bar structure.

That is, referring to Figure 2b, the planar insert 110 is lowered in the side connection space (S) of the precast wall 200, the rotation overlapping member 130 installed so as to be rotatable in the planar insert 110 is In the process of making contact with the connecting reinforcing bars 210, it is repeatedly overlapped with the planar insert 110 and folded upward,

When the planar insert 110 touches the floor G of the side connection space S, the rotary overlapping member 130 is automatically set on a plurality of connecting reinforcing bars 210 horizontally,

It can be seen that the rotating overlapping material 130 is arranged between the upper and lower sides of the connecting reinforcing bars 210 of the side connection space (S) of the precast wall.

Accordingly, the flat insert 110 is extended in length over the entire height of the side connection space (S), and when the tip of the rotating overlapping member 130 touches the floor (G) of the side connection space (S), it rotates Determine the formation position (d1) of the lowermost rotating overlapping material 130 from the lower end of the planar insert 110 so that the overlapping material 130 can be set horizontally while being in contact with the connecting reinforcing bar 210,

The distance between each of the remaining rotating overlapping members 130 (d2, d3....dn ==> n distances are determined according to the number of formation of the rotating overlapping members)) also on the connecting reinforcing bar 210, the rotating overlapping member ( 130) is formed to be located,

The connecting reinforcing bar 210 and the rotating overlapping member 130 can be naturally formed in an overlapping reinforcing bar structure while the rotating overlapping member 130 is horizontally contacted on the vertically spaced connecting reinforcing bars 210 .

As a result, the separation distance h1 between the connecting reinforcing bars 210 and the formation position d1 of the lowermost rotating overlapping member 130 and the distances d2, d3....dn between each rotating overlapping member 130 are mutually When set to be the same, when the planar insert 110 comes into contact with the floor G of the side connection space S, the rotating overlapping member 130 is automatically set on a plurality of connecting reinforcing bars 210 horizontally can become

Referring to FIGS. 2A and 2B , for example, the rotation overlapping material 130 is in the form of a rectangular ring so that it can be set horizontally by rotation using the same member as the planar insert 110 . ) One end is hinge-connected including a hook to the intermediate connecting member 113 of the planar insert 110 .

Accordingly, the rotating overlapping member 130 hingedly connected to the planar insert 110 is descended and even in contact with the connecting reinforcing bar 210, the process of overlapping with the planar insert 110 while rotating upward is repeated, so that the final lowermost connecting reinforcing bar 210 ) to be placed horizontally on the

The separation distance (d1, d2, d3,,,) of each of the rotary overlapping members 130 is formed in response to the separation distance (h1) of the connecting reinforcing bar 210, so that the final rotary overlapping material 130 is inserted in a planar shape without any other means In the process of being lowered to the ash 110 , it can be set horizontally and naturally horizontally on the connecting reinforcing bar 210 .

Next, as shown in FIGS. 3A, 3B, and 3C, the insertion reinforcement 150 is vertically set from the ground when the connecting reinforcing bar 210 is formed as an overlapping reinforcing bar by the horizontal setting operation by the rotation of the rotating overlapping material 130. As a reinforcing material inserted into the side connection space (S) to penetrate the connecting reinforcing bar 210 and the rotating overlapping member 130, a reinforcing bar inserted vertically can be used.

Accordingly, the connecting reinforcing bar 210, the planar inserting material 110, and the rotating overlapping material 130 are synthesized with each other by the injected injection material 230 and integrated in the side connection space S to form the precast wall 200 structurally. It plays a role in completing the continuity.

At this time, it is common to use non-shrinkable concrete as the injection material 230, but injection is easy, and the curing time is short, so that the side connection space S can be finished quickly.

Accordingly, since it is desirable to reduce the amount of injection material by minimizing the side connection space (S), the side connection space (S) is formed in consideration of this when the precast wall 200 is manufactured.

As a result, when the size of the side connection space (S) is minimized, the amount of injection material used is reduced, but it may be difficult to vertically insert the rotary reinforcing bar sequencing device 100 into the side connection space (S).

However, the rotary overlapping reinforcing bar sequencing device 100 of the present invention allows the operator along the side (A) of the precast wall 200 to the side connection space (S) to have the rotary overlapping member 130 hingedly connected to the planar insert 110 ) can be set horizontally between the connecting reinforcing bars 210 only by vertically lowering it, so that there is no difficulty in vertical insertion due to the minimized side connection space (S), especially the precast wall The efficient fabrication of (200) is possible.

As such, the rotary type overlapping reinforcing bar sequencing device 100 of the present invention is,

As shown in Figure 3a, the side connection space (S) can be installed in a state in which the precast wall 200 is spaced apart from each other,

3b and 3c, the side connection space (S) can be formed naturally while the connection flanges 220 of the precast wall 200 are in contact with each other, and regardless of the size of the side connection space (S), the rotation overlaps It can be seen that the apparatus 100 for sequencing the overlapping reinforcement of the precast wall using the ash 130 can be installed by vertically inserting it along the side surface (A) of the precast wall 200 .

[The construction method of the rotary type overlapping reinforcing bar sequencing device 100 of the present invention]

Figures 4a, 4b and 4c shows a flow chart of the construction method of the rotary type lap reinforcing bar sequencing device 100 of the present invention.

The construction method of the rotatable overlapping reinforcing bar sequencing device 100 is constructed so that the precast walls 200 are adjacent to each other in the basement or the ground, but the connecting reinforcing bars 210 are not overlapped with each other in the side connection space (S). As a construction method to form an overlapping reinforcing bar structure with each other using the overlapping reinforcing bar sequencing device 100, the final injection material 230 is injected into the side connection space S to integrate the precast wall 200 with each other. can

Accordingly, as shown in Fig. 4a, the precast wall 200 is manufactured and brought into the site, the precast wall 200 is inserted and installed, and the rotary type reinforcing bar sequencing device 100 is lowered from the upper part of the side connection space (S). set up to make it happen.

The precast wall 200 is in the form of a reinforced concrete vertical wall having a certain height, and a plurality of connecting reinforcing bars 210 extending horizontally are installed horizontally by being spaced apart from each other up and down.

In addition, on the side of the precast wall 200, the connection flange 220 is formed so that the side connection space (S) can be formed, and 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.

At this time, the connecting reinforcing bar 210 is to have a constant vertical separation distance h1. Based on this separation distance h1, the lowermost end and the remaining rotation overlapping material 130 of the rotary type overlap reinforcing bar sequencing device 100 to be described later. The separation distance (d1, d2, d3..) is determined.

That is, the separation distance (d1, d2, d3..) of the entire rotary overlapping member 130 is set so that it is equal to or slightly larger than the spacing distance h1 of the connecting reinforcing bar 210, and the rotary overlapping member 130 is connected to the connecting reinforcing bar ( 210) so that it can be set horizontally between them.

Accordingly, the precast wall 200 manufactured in advance in a factory, etc. is brought into the field, and the precast wall 200 is lifted and prepared to be lowered, and the connecting reinforcing bars 210 are set to face each other horizontally. However, it can be seen that it is not in a state where it is not set to an overlapping reinforcing bar structure.

At this time, it can be seen that the rotary overlapping reinforcing bar sequencing device 100 is a state in which a plurality of rotary overlapping members 130 are hingedly connected to the planar insert 110, and the rotary overlapping member 130 is a planar insert by its own weight. (110) is in an overlapping state in the extension direction. Therefore, it is preferable that the operator initially set the rotation overlapping material 130 to be rotated and contacted horizontally so that the rotation overlapping material 130 inserted of the planar insert 110 is not caught on the first connecting reinforcing bar 210 . Do.

Next, as shown in Fig. 4b, in the process of lowering the tip of the rotary reinforcing bar sequencing device 100 in the side connection space (S) to be supported on the floor (G) of the side connection space (S), the rotating overlapping material 130 ) is set to be in a horizontally rotated state between the connecting reinforcing bars 210 .

In the side connection space (S) in which the connecting reinforcing bars 210 spaced horizontally from each other up and down are formed, the planar insert 110 of the rotary overlapping reinforcing bar sequencing device 100 is disposed on a vertical plane and can be lowered, Without interfering with the connecting reinforcing bar 210, it is possible to vertically lower and insert it along the side of the precast wall 200 and the like.

That is, even if the side connection space (S) is minimized, using the space not occupied by the connecting reinforcing bars 210, the overlapping reinforcement continuation apparatus 100 of the precast wall using the rotating overlapping material 130 in the side connection space (S) is lowered can be inserted and installed.

Accordingly, after the rotation overlapping member 130 hingedly connected to the planar insert 110 is initially set to be in contact with the first connecting reinforcing bar 210 horizontally, that is, under the first connecting reinforcing bar 210 . Since the rotary overlapping member 130 is in contact with the located connecting reinforcing bar 210 before being folded upward, only the lowering of the rotary overlapping reinforcing bar sequencing device 100 causes the rotary overlapping member 130 to descend while continuing to be folded upward. be able to do

At this time, as described above, when the tip of the planar insert 110 touches the floor G, the rotating overlapping material 130 can be set horizontally while in contact with the connecting reinforcing bar 210, the rotating overlapping material ( The formation position (d1) of the lowermost rotary overlapping member 130 from the lower end of 130 is determined, and the distance (d2, d3...dn) between each rotary overlapping member 130 is the separation distance of the connecting reinforcing bar 210 ( h1), the connecting reinforcing bar 210 and the rotating overlapping member 130 naturally overlap each other while the rotating overlapping member 130 is in horizontal contact on the vertically spaced connecting reinforcing bars 210. can become

Next, as shown in Fig. 4c, after lowering and inserting the insertion reinforcing material 150 into the connecting reinforcing bar 210 of the precast wall formed to be vertically spaced apart, the injection material 230 is injected into the side connection space (S) and connected. The reinforcing bar 210 and the overlapping reinforcing bar sequencing device 100 of the precast wall using the rotating overlapping material 130 are integrated with each other.

The injection material 230 may use a non-shrinkable mortar, etc., and since the rotation overlapping material 130 of the rotary type overlapping reinforcing bar sequencing device 100 is set between the upper and lower connecting reinforcing bars 210, insert the reinforcing material 150. It can be installed so as to vertically penetrate the connecting reinforcing bar 210 and the rotating overlapping member 130,

In this state, when the injection material 230 is injected into the side connection space S from the upper portion, the 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 closed with the injection material 230, the planar insert 110 heads are finally finished (cutting, etc.) In this way, the construction is completed, and the precast wall 200 as above can be serialized underground and on the ground by using the rotary reinforcing bar sequencing device 100 .

The description of the present invention described above is for illustration, and those of ordinary skill in the art to which the present invention pertains can 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.
