The unnecessary rebar is not installed at a location where a compressive force is applied by bending moment, thereby significantly reducing costs.

Description

Connecting Structure and Connecting Method of Segmented Member

The present invention relates to a structure and a method for integrally connecting two segment members made of a precast concrete member. More specifically, the present invention relates to a structure and a method for integrally connecting two segment members, The reinforcing bars for binding are protruded at intervals between the segment members and the joint members such as concrete are laid on the spacing between the segment members so that the segment members are integrally connected to each other, It is possible to improve workability by inserting a hand or a tool in an operator's room so as to easily carry out a necessary operation. In addition, at a position where a compressive force is applied by the bending moment at the connecting portion of the segment members, A new type of reinforced concrete reinforced concrete (FRP) To " connection structure and connection method of segment members "

A technique for constructing a structure such as a tunnel or a bridge by arranging segment members made of precast concrete members adjacent to each other and firmly integrating them with each other has been proposed. For example, Korean Patent Registration No. 10-1491952 A technique for constructing an arch structure using two segment members is disclosed. For the sake of convenience, the precast concrete members that are arranged adjacent to each other and integrally joined together to construct the structure are referred to as "Segment Members ". In this specification, the direction in which the segment members are connected to each other and connected to each other is referred to as "lateral direction " for convenience, and the direction orthogonal to the direction is referred to as" longitudinal direction ". The toe direction of the segment members is described as "vertical direction ".

In constructing the structure by joining the segment members, the loop reinforcement is exposed to the transverse spacing ("connecting portion") between the adjacent segment members connected to each other and the loop reinforcement is embedded in the connecting portion A method of filling and hardening the filler is used. However, in the conventional technique of this type, there is a problem that an excessive number of reinforcing bars are arranged in the connecting portion. Since the loop reinforcement is extended from each of the segment members adjacent to each other, the loop reinforcement extending from each of the segment members is simultaneously present in the connection portion, so that the number of loop reinforcements extended from the respective segment members There is a loop reinforcement corresponding to 2 times. That is, if N loop protrusions are protruded from each of the segment members, 2N loop bars are present in the connection portion.

Each loop reinforcement consists of two reinforcing bars extending in the transverse direction and continuing to each other by a curved portion, i.e., an upper reinforcing bar and a lower reinforcing bar. When a bending moment acts on the connection, one of the upper and lower bars will resist the tensile force and the other will resist the compressive force. The amount of tensile reinforcement that resists tensile force is adjusted to be within the maximum allowable reinforcement ratio. Since the amount of compression reinforcement that resists compressive force is equal to the amount of tensile reinforcement, the amount of compression reinforcement is excessively unduly excessive do. This results in an inefficient reinforcement and thus a waste of unnecessary costs.

Particularly, in order to stably fix the loop reinforcement and to connect longitudinally the segment members, longitudinal reinforcing bars must be arranged in the connecting portion. As described above, a large number of loop reinforcing bars are provided in the longitudinal direction It is very difficult to carry out the task of placing the longitudinal rebar in the designed position by inserting the hand or tool between the loop reinforcements by the operator. That is, the prior art has a disadvantage in that workability for placing the longitudinal reinforcing bars in the connecting portion is very poor.

Korean Patent Registration No. 10-1591952 (published on Mar. 26, 2012).

The present invention has been developed in order to overcome the limitations of the prior art as described above, and it is an object of the present invention to provide a method and apparatus for reinforcing a reinforcing bar in a connecting portion and filling a filling bonding material, And to provide a connecting structure and a connecting method of a segment member that can solve the problem of unnecessary cost caused by excessive laying of reinforcing bars in the prior art.

Further, according to the present invention, by expanding the longitudinal distance between the projected reinforcing bars in the connecting portion, it is possible to secure a wider space for the worker to insert a hand or a tool in the connecting portion, and when the longitudinal reinforcing steel reinforcement is required, And to provide a connecting structure and a connecting method of a segment member which can improve the workability of the reinforcing bars of the directionally reinforcing bars so that the longitudinal reinforcing bars can be easily and quickly positioned at the designed positions.

In order to achieve the above object, according to the present invention, there is provided a connection structure of a segment member which integrally connects segment members made of precast concrete members laterally adjacent to each other, On the connecting side facing each other, a plurality of loop reinforcing bars and a plurality of hook reinforcing bars are projected in the lateral direction; The loop reinforcement is composed of an upper reinforcing bar located on the upper side in the vertical thickness of the segment member, a lower reinforcing bar located on the lower side, and a curved reinforcing bar connecting the upper and lower reinforcing bars at the outer ends of the upper and lower reinforcing bars, Lt; / RTI > The hook reinforcement comprises a horizontal reinforcement and a continuous bending reinforcement bent at a transverse outer end of the horizontal reinforcement to form a hook shape; The loop reinforcement and the hook reinforcement are arranged at longitudinal intervals in the longitudinal direction in each of the segment members so that their order is alternated with each other; A protruding lower portion protruding in the direction of the connection portion is provided below the loop reinforcing bars and the hook reinforcing bars at the connection side of both the side member members or the one side member; When the two side members are disposed adjacent to each other in the transverse direction for connection, the loop reinforcement and the hook reinforcement provided in the two side members are arranged to overlap each other at positions displaced from each other. Interrupting the lateral spacing between the two side members at the bottom of the rebar and the hook reinforcement; Wherein the filling member is filled in a connecting portion which is a space above the protruding portion and the filling member is cured in a state in which the loop reinforcing bar and the hook reinforcing steel are embedded so that the two connecting members are continuously joined together. And a method of connecting the segment members to form such a connection structure.

In this invention, in the hook reinforcement, the horizontal reinforcement is at the lower reinforcement position of the loop reinforcement and the bending reinforcement is bent vertically upward at the outer end of the horizontal reinforcement; The connection structure of the segment members may be formed in a structure in which a tensile force is generated in the lower reinforcing bar of the loop reinforcement and a bending moment in the form of a moment-like force is generated in the upper reinforcing bar of the loop reinforcement.

Alternatively, in the present invention, in the hook reinforcement, the horizontal reinforcement is at the upper reinforcement position of the loop reinforcement and the bending reinforcement is bent vertically downward at the outer end of the horizontal reinforcement; The connection structure of the segment members may be formed in a structure in which a tensile force is generated in the upper reinforcing bar of the loop reinforcement and a bending moment in the form of a mandrel, which generates compressive force, is applied to the lower reinforcing bar.

According to the present invention, two loop members, each of which is formed in the form of a segment, are integrally joined together by a loop reinforcing bar and a coupling filler, and a hook bar having a shape bent in a hook shape is positioned between the loop bars It is possible to prevent excessive reinforcement from being unnecessarily placed at a position where a compressive force acts due to a bending moment at a portion where the segment members are connected, thereby reducing the cost of using reinforcing bars, thereby improving the economics of construction .

Particularly, in the present invention, when the hook reinforcement is made of a horizontal reinforcement and a bending reinforcement bent in a vertically upward direction, a portion of the upper reinforcement is interposed between the reinforcement disposed at a connection portion between the segment members, There is a nonexistent extension section, and a space is provided in which the operator can insert a hand or a tool into the connection section, thereby improving the work efficiency in the connection section.

Alternatively, in the present invention, when the hook reinforcing bar has a shape composed of a horizontal reinforcing bar and a vertically downwardly bent bent reinforcing bar, when the longitudinal reinforcing bars are disposed in the connecting portion, The lower reinforcing bars which are obstructed are reduced in comparison with those made of only the loop reinforcing bars, so that the arrangement work of the longitudinal reinforcing bars can be carried out easily and quickly.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its essential structure and operation are not limited thereby.

1 and 2 show schematic perspective views showing different directions in which the two segment members 1 approach each other in a lateral direction to be connected according to the first embodiment of the present invention, 3 is a schematic plan view of the state shown in FIG. 1, viewed from top to bottom. As shown in the drawing, in the present invention, a plurality of loop reinforcing bars 2 and a plurality of claw bars 3 are projected in the transverse direction on the connecting side of the segment member 1, that is, the side facing the connecting portion. The loop reinforcement 2 is composed of an upper reinforcing bar located on the upper side in the vertical thickness of the segment member 1, a lower reinforcing bar located on the lower side, and a curved reinforcing bar connecting the upper and lower reinforcing bars at the outer ends of the upper and lower reinforcing bars And has a closed loop shape. An end portion of the loop reinforcement 2 in the connection side direction, that is, an inner end portion thereof, is embedded in the segment member 1. On the other hand, the hook reinforcement 3 comprises a horizontal reinforcement 30 and a bending reinforcement 31 bent at the lateral outer end of the horizontal reinforcement. The inner end of the horizontal reinforcing bar 30 is embedded in the segment member 1. 1 to 3, the horizontal reinforcing bars 30 are located at the lower reinforcing bars of the loop reinforcement 2 and the bending reinforcing bars 31 are bent vertically upward at the outer ends of the horizontal reinforcing bars 30 Shape.

A plurality of the loop reinforcing bars 2 and the hook reinforcing bars 3 are provided on the connecting side surfaces of the segment members 1 which are elongated in the longitudinal direction and the loop reinforcing bars 2 and the hook reinforcing bars 3 Are arranged at longitudinally spaced intervals, the orders of which are arranged alternating with each other. That is, in the longitudinal direction, the loop bar 3 is positioned at a longitudinal distance from the loop bar 2, and another loop bar 2 is positioned at a longitudinal distance from the bar rebar 3, . In other words, the hook reinforcement 3 is positioned at the center of the gap between the loop reinforcements 2 in the longitudinal direction and the loop reinforcement 2 is positioned at the center of the gap between the hook reinforcement 3 . 3, the loop reinforcement 2 is shown in a straight line and the hook reinforcement 3 is shown in a dotted line so that the loop reinforcement 2 and the hook reinforcement 3 can be distinguished from each other.

On the other hand, at the connection side of the segment member 1, a protruding lower portion 10 extending in the direction of the connection portion can be formed below the loop reinforcement 2 and the hook reinforcement 3, All of the two side members 1 are provided with a protruding lower portion 10 such that when the two side member 1 are disposed laterally adjacent to each other for connection, Are brought into contact with their lateral sides. At this time, the loop reinforcing bars 2 and the hook reinforcing bars 3 provided on the both side member 1 are overlapped with each other, and the protruding lower portions 10 are formed by overlapping the loop reinforcing bars 2, And the lateral spacing between the two side members 1 under the hook reinforcement 3 is blocked.

Fig. 4 shows a schematic perspective view in which the protruding lower portions 10 provided on the two segment members 1 are arranged so as to be in contact with each other in the transverse direction, following the state shown in Figs. 1 and 2, A top plan view of the state shown in FIG. 4 is shown from top to bottom. FIG. 6 is a schematic perspective view corresponding to FIG. 4 showing a state in which a connection portion above the protruding lower portion 10 in a state shown in FIG. 4 is filled with a coupling filler material 4 such as concrete. 7 and 8 show a schematic cross-sectional view of the state shown in Fig. 6 in the longitudinal direction. Fig. 7 shows a cross-sectional view taken along the line AA corresponding to the position where the loop reinforcement 2 is laid, Sectional view, and Fig. 8 is a cross-sectional view taken along the line BB, which corresponds to the position where the hooking bar 3 is laid, and is viewed in the longitudinal direction.

As shown in the figure, when the two side members 1 are arranged so as to be opposed to each other in the transverse direction so that the ends of the projecting lower portion 10 are in contact with each other, in the connecting portion formed above the projecting lower portion 10, The loop reinforcing bars 2 and the hook reinforcing bars 3 protruding from the connection side face of the hook reinforcement 1 are disposed so as to overlap each other at positions displaced from each other. In this state, the filler material 4 such as concrete is filled in the connection portion which is the space above the protruding lower portion 10, and the filler material 4 is filled in the state where the loop reinforcement 2 and the rebar 3 are embedded. So that the two side members 1 are firmly and integrally joined together in a continuous manner.

In the present invention, when the loop reinforcement 2 and the hook reinforcement 3 are provided on the connection side of the one side member 1, the loop reinforcement 2 and the rebar reinforcement 3 are alternately arranged in the longitudinal direction 5, there are cases where there are two claw bars 3 which are superimposed on each other in a longitudinal gap between two loop reinforcing bars 2 superimposed one upon the other, There are cases in which two loop reinforcing bars 2 are overlapped with each other in longitudinal intervals between two hook bars 3 arranged to overlap each other. That is, when the longitudinal spacing between the loop reinforcement 2 and the hook reinforcement 3 in the one side member 1 is S, the longitudinal spacing between the two loop reinforcements 2 superimposed on each other is 3 / 2S. ≪ / RTI >

In the case where only one loop reinforcement is present in each of the two segment members, when the longitudinal spacing between the loop reinforcements provided on the one segment member 1 is S, The longitudinal spacing between the loop bars existing in the longitudinal direction is 1 / 2S, and only the interval of 1 / 2S exists in the longitudinal direction. However, in the present invention, as described above, since the loop reinforcement 2 and the hook reinforcement 3 are provided alternately in each of the two side members 1, the two side members 1 ("Extended section") which is extended to the longitudinal spacing 3 / 2S between the reinforcing bars existing in the connecting section.

As described above, according to the present invention, since the extended section is formed between the reinforcing bars at the connecting portion, the operator can easily insert the hand or the tool into the extended section. Therefore, it is very easy to arrange the longitudinal reinforcing bars in the designed position in the connecting portion It is possible to greatly increase the efficiency of the longitudinal rebar laying work performed in the connection portion.

In the case of the first embodiment shown in Figs. 1 to 8, the hooking bar 3 is composed of a horizontal reinforcing bar 30 located at the lower reinforcing bar of the loop reinforcement 2 and a bending reinforcing bar 31 vertically upward , And the reinforcing bars corresponding to the upper reinforcing bars of the loop reinforcing bars (2) are not provided in the reinforcing bars (3). Therefore, as described above, there is an extended section between the reinforcing bars at the connecting portion in which the two side members 1 are arranged to face each other in the transverse direction, and this eventually exists in the upper side in the thickness direction of the segment member The amount of reinforcing bars is reduced compared to the case where only the loop reinforcing bars are present in each of the two side members. When a compressive force is applied to the upper reinforcing bar portion due to a bending moment of positive positive moment acting on the connecting portion of the two side member 1, It is possible to prevent the excessive compression reinforcement in the compressive force acting portion, which is a problem of the related art, and the occurrence of the inefficiency of the reinforcing steel reinforcement and the cost wasting problem.

1 to 8, the horizontal reinforcing bars 30 are located at the lower reinforcing bars of the loop reinforcing bars 2 and the bent reinforcing bars 31 are located at the lower reinforcing bars of the horizontal reinforcing bars 30, As shown in Fig. However, in the present invention, the shape of the hook reinforcement 3 is such that the horizontal reinforcement 30 is present at the "upper reinforcement" position of the loop reinforcement 2 and the bending reinforcement 31 is located at the outer end of the horizontal reinforcement 30, Vertically downward "

FIG. 9 is a schematic perspective view showing a state in which two segment members having a hook reinforcement modified in accordance with a second embodiment of the present invention approach to be laterally connected, and FIG. And FIG. 11 is a schematic plan view of the state shown in FIG. 10, which is viewed from the top downward. FIG. 11 is a schematic perspective view of the state in which the lower portions of the protrusions provided on the two segment members are arranged to be in contact with each other in the transverse direction. Are shown. FIG. 12 is a schematic perspective view corresponding to FIG. 10 showing a state in which a connection portion above a protruding lower portion in a state shown in FIG. 10 is filled with a coupling filler such as concrete. FIG. Sectional view taken along the line CC corresponding to the position where the hooking bar 3 is laid out in FIG. 12 and is viewed in the longitudinal direction. As shown in FIG. 11, the loop reinforcement 2 is shown in a straight line and the hook reinforcement 3 is shown in a dotted line so that the loop reinforcement 2 and the hook reinforcement 3 can be distinguished from each other.

 In the present invention according to the second embodiment shown in Figs. 9 to 13, the hook reinforcement 3 is composed of the horizontal reinforcement 30 and the horizontal reinforcement 30, which are present at the "upper reinforcement" And a bending steel bar 31 bent in a "vertical downward" The loop reinforcement 2 and the hook reinforcement 3 are arranged alternately in the longitudinal direction at intervals on the connecting side of the other segmental members 1. When the two side segments 1 approach each other and the connecting side faces each other The configuration in which the loop reinforcement 2 and the hook reinforcement 3 are disposed in the middle of the gap and the configuration in which the coupling filler 4 is filled are the same as those of the first embodiment of the present invention described above. do.

In the case of the second embodiment, as viewed from the top of the connection portion, unlike the first embodiment, there is no extended section between the reinforcing bars existing in the connecting portion in the state where the two side members 1 face each other, 3 is composed of the horizontal reinforcing bar 30 and the bending reinforcing bars 31 in the "vertical downward direction", the hook reinforcement 3 is not provided with the horizontal reinforcing bar at the position where the lower reinforcing bar of the loop reinforcing bar 2 exists, Only the lower reinforcing bar of the loop reinforcement 2 is present on the "lower side" in the vertical thickness of the member. Therefore, when a bending moment in the form of a negative moment acts on the connecting portion of the two side member 1 to cause a tensile force at the upper reinforcing bar position and a compression force at the lower reinforcing bar position, in the second embodiment, It is possible to prevent the excessive compression reinforcement in the compressive force acting portion and the resulting inefficiency of the reinforcing steel reinforcement and the occurrence of the cost wastage problem because the amount of the compression reinforcing bars existing on the lower side in the direction thickness is reduced.

Although not shown in the drawing, a longitudinal reinforcing steel bar extending elongated in the longitudinal direction can be provided to the connecting portion where the loop reinforcement 2 and the hook reinforcing bar 3 are superposed, The reinforcing bars are inserted in the connecting portions so as to penetrate the loop reinforcement bars 2 in the longitudinal direction. At this time, due to the heavy weight of the longitudinal rebar, the operator performs the placement work of the longitudinal rebar in the form of pushing the longitudinal rebar on the lower rebar of the loop reinforcement (2) in the longitudinal direction.

Theoretically, if the roof reinforcing bars 2 protruding from the connecting side of the two side members 1 are disposed at the correct positions in a mirror-symmetrical relationship in the transverse direction, the loop reinforcement 2, when viewed from the connecting portion in the longitudinal direction, Should be present in one plane. However, in manufacturing the actual segment member 1, there is a small error in the vertical position of the loop reinforcement 2. For this reason, in the state where the two side segment members 1 are continuously arranged in the transverse direction, As you look, the lower reinforcing bar of the loop reinforcement 2 does not exist in one plane and is located in a rugged irregular shape. In this state, when the longitudinal reinforcing bar is pushed to the longitudinal direction while the longitudinal reinforcing bar is placed on the lower reinforcing bar of the loop reinforcing bar (2), the longitudinal reinforcing bar is obstructed by the lower reinforcing bar of the loop reinforcing bar It is very difficult to arrange the longitudinal reinforcing bars and the working time is increased.

However, in the case of the second embodiment as described above, since the hook reinforcement 3 is disposed between the loop reinforcement 2 and the hook reinforcement 3 does not have a member corresponding to the lower reinforcement, The number of the lower reinforcing bars which obstruct the progress of the longitudinal reinforcing bars in the longitudinal direction is reduced as compared with the case of only the loop reinforcing bars, Time is also shortened. In other words, according to the second embodiment, it is possible to easily perform the laying work of the longitudinal reinforcing steel bars and to reduce the work time, compared with the case where only the loop reinforcing bar exists only in each of the two side members.

 In the first and second embodiments of the present invention, the protruding lower portion 10 is provided in each of the two side members 1, and when the two side members 1 are arranged in the lateral direction, The side surface of the lower portion 10 abuts against each other, and a connecting portion, which is a space in which the loop reinforcing bars 2 and the hook reinforcing bars 3 are overlapped, is formed above the lower reinforcing bars. However, even if the protruding lower portion 10 is provided on both of the side member 1, the protruding lower portion 10 may be present only on one of the two side members 1, May be different from each other. Fig. 14 shows a schematic perspective view corresponding to Fig. 4 for an embodiment in which only one of the segment members of the two side members 1 has the protruding lower portion 10 as another embodiment of the present invention. 14 are the same as those of the first and second embodiments, and therefore, a repetitive description thereof will be omitted.
