Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a column-to-beam joint structure in a concrete structure and a construction method thereof.

"Prior Art and its Problems" For example, when constructing a reinforced concrete structure, reinforcement at the joints between columns and beams has conventionally been generally assembled on-site.

However, reinforcing work at the joints between columns and beams on-site is extremely time-consuming because the reinforcing bars intersect in a complex manner from above and below, left and right, and front and rear. (Arrangement spacing of reinforcement, beam main reinforcement, column main reinforcement, etc.)
was difficult, and improvements have been awaited.

By the way, as a reinforcement arrangement alternative to on-site assembly, conventionally, multiple column main reinforcements or beam main reinforcements are tied together using shear reinforcing bars (tie bars, stirrup bars, etc.) to form a unit (column structural member) with a predetermined size. There is a construction method in which columns and beams of a building are constructed by assembling the assembled pillar main reinforcements and beam main reinforcement units into different units (such as structural members for beams), and then assembling the assembled pillar main reinforcement and beam main reinforcement units with each other.

To explain an example of the work procedure of this construction method,
First, a structural member for a column without shear reinforcing bars attached to the upper end of one story is erected at the construction location, and then the two beams are pre-assembled at the upper end so that they are orthogonal to each other on the same plane. In addition, the joint unit of the main beam reinforcement will be suspended upward by a crane, etc.

Then, the joint unit of the beam main reinforcement suspended by a crane etc. is positioned so that the column main reinforcement and the beam main reinforcement cross each other and the column main reinforcement passes through the gap formed by the beam main reinforcement. After adjusting and gradually lowering the main beam reinforcement unit to a predetermined position, the position is fixed by each main reinforcement and auxiliary reinforcement. In this way, the column main reinforcements are arranged between the plurality of beam main reinforcements.

Thereafter, a beam structural member is connected and arranged to the joint unit of the beam main reinforcement, and each main reinforcement is further connected by a joint. By repeating this process, the columns and beams of the reinforced concrete structure are constructed.

However, even with this construction method, problems remain, such as the following.

■ When placing a column main reinforcement between multiple beam main reinforcements, the column main reinforcements and beam main reinforcements are assembled so that the column main reinforcements pass through the gap formed by the beam main reinforcements, so there may be dimensional deviations between the column main reinforcements and the beam main reinforcements. If there is such a problem, it will be difficult to adjust the misalignment, and it will be difficult to lower and install the joint unit of the main beam reinforcement in the specified position.

■ Because the upper end of the column main reinforcement (the part to be the joint) passes through the gap formed by the beam main reinforcement, it takes a long time to adjust the position of the joint unit of the beam main reinforcement, and it is difficult for workers to adjust the horizontal position. The risk will also increase.

■ Since it is not possible to place shear reinforcing bars in the joints of columns, this becomes a structural weakness.

The present invention has been made in view of the above-mentioned circumstances, and provides a structure for a joint between a column and a beam in a concrete structure and a method for constructing the same. The purpose is to provide.

"Means for Solving the Problem" Therefore, in the joint structure of the first invention, a column structural member assembled by a plurality of column main reinforcements and a plurality of shear reinforcements, a plurality of beam main reinforcements and a plurality of shear reinforcement It includes a beam structural member assembled by reinforcement, and a joint structure that is set at a predetermined position of the column structural member and connects the beam structural member in an axial direction perpendicular to the length direction of the column structural member. and the joint structure has a plurality of joint members that are arranged in parallel at intervals in the width direction of the column structural member and connect the beam structural members, and the joint member is connected to the column main reinforcement. A pair of upper and lower beam connecting main bars that are inserted into the mesh of the and shear reinforcing bars and connected to the upper and lower beam main bars of the beam structural member, and a pair of upper and lower beam connecting main bars that are installed only on one side of these pairs of upper and lower beam connecting main bars to connect the upper and lower beams. It is composed of a connecting reinforcement that integrates the main reinforcing bars, and the length dimension of the beam connecting main reinforcing bars is set so that the insertion end thereof protrudes to the outside of the column structural member.

In addition, the construction method of the second invention includes a step of assembling a column structural member consisting of a column main reinforcement and a shear reinforcing bar in advance and erecting it at the construction position, and A process of forming a plurality of joint members each consisting of a pair of beam connecting main reinforcements and connecting bars that integrate the upper and lower pair of beam connecting main reinforcements, arranging these joint members in the width direction of the column structural member, and inserting the beam connecting main reinforcements. A step of setting a plurality of joint members in the width direction of the column structural member by inserting the ends into a mesh of the column main reinforcement and shear reinforcing bars and protruding to the opposite side of the column structural member; The method includes a step of connecting beam structural members made up of main reinforcements and shear reinforcing bars.

"Function" According to the present invention, the set position of the beam structural member can be determined by the simple operation of erecting the column structural member and inserting the joint member into the mesh of the column main reinforcement and shear reinforcing bar. Since the structural members for the beams can be joined through the members, it is possible to improve workability and safety on site, and it is possible to shorten the construction period.

In addition, if each component (column main reinforcement, beam main reinforcement, shear reinforcement, beam connection main reinforcement, connecting reinforcement, etc.) is made of continuous fibers coated with resin, the weight of the column structural members and beam structural members can be reduced. This is preferable because it can further improve on-site work efficiency.

"Example" Hereinafter, the joint structure of a column and a beam in a concrete structure according to the present invention and its construction method will be described in accordance with the construction order with reference to FIGS. 1 to 5.

In one embodiment, an example is shown in which the present invention is applied when constructing a joint between a pillar located at the center of a structure and a beam connected thereto.

(i) Structural members for housing and beams and N'1 (7) Formation of members In the diagram, reference numeral 1 is a groove member for columns, 2 is a structural member for columns, and 3 is a joint member.

A plurality of surface housing structural members 1 (16 in the embodiment) are arranged in parallel so as to extend in the vertical direction and are located on the sides of a rectangle.
It is assembled to a length corresponding to the height of one layer of the structure, for example, by the main column reinforcements 4 of the present invention and a plurality of shear reinforcing bars 5 that connect the main column reinforcements 4. In addition, connecting fasteners (for example, sleeve joints, etc.) are attached to the upper and lower ends of this structural member l for pillars, so that structural members 1 for pillars having the same configuration can be connected above and below. It has become.

The beam structural member 2 includes a beam unit 2a in which a plurality of beam main reinforcements 6 extending in the length direction of the beam and parallel at intervals in the width direction are held at constant intervals by a plurality of connection reinforcements 7a; It is constituted by a ring-shaped shear reinforcing bar 8 that is wound around the outer periphery of the beam unit 2a.

As shown in FIGS. 2 and 3, a lap joint length is formed at both ends of the beam structural member 2, and is configured to be connected to the joint member 3 as a lap joint. There is.

In the case of the embodiment shown in the drawings, the shear reinforcing bars 8 leave a lap portion (lap joint portion) with the joint member 3, and are attached to the beam unit 2a at a predetermined interval in the longitudinal direction of the beam unit 2a. (: It is integrated, and shear reinforcing bars 8 are arranged in the lap part after joining with the joint member 3. As shown in FIG. 2, the upper and lower beam units 2a By providing connecting reinforcements 7a between the upper and lower beam main reinforcements 6, the strength of the beam structural member 2 can be improved, and
This is preferable because the structure member 2 for rice cake can be easily positioned with respect to the insertion end 9a side of the joint member 3.

On the other hand, the shear reinforcing bars 8, which are arranged every few inner and reverse sides of these shear reinforcing bars 8, are provided with protruding parts 8a that protrude from the lower surface of the shear reinforcing bars 8. The concrete coating thickness is maintained between the main reinforcing bars 6 and the main reinforcing bars 6.

In the embodiment shown in the drawings, the shear reinforcing bars 8 are integrated into the beam unit 2a in advance. The shear reinforcing bars 8 may be installed in a form inserted into the beam unit 2a, and after joining with the joint member 3, the shear reinforcing bars 8 may be arranged at regular intervals and integrated with the outer periphery of the beam unit 2a.

Next, the joint member 3 that joins the structural member 2 for pillars to the structural member 1 for pillars will be explained. This is a joint member 3 that penetrates the structural member 1 for pillars at a predetermined interval in the width direction and perpendicularly to the axial direction of the structural member 1 for pillars. It connects the beam assembly structural members 2 located at opposing positions of the structural member I for rice bran. 2 are connected in two axial directions perpendicular to the length direction of the pillar structural member l.

The concrete structure of this joint member 3 includes a pair of upper and lower beam connecting main reinforcements 9 arranged along the upper and lower main beam reinforcements 6 of the structural member 2 for rice bran and connected to these main beam reinforcements 6, respectively. It consists of a plurality of (three in the illustrated example) connecting bars 10 that are provided on one side of the beam connecting main bars 9 and connect the beam connecting main bars 9 together.

The insertion end 9a of the surface beam connecting main bar 9 is connected to the column structural member l.
The length dimension of the connecting bar 10 located at the center of the connecting bars IO is set such that the lower end 10a of the connecting bar 10 protrudes from the lower surface of the beam connecting main bar 9. When setting the beam formwork, a predetermined concrete coating thickness is maintained between the beam formwork and the beam connecting main reinforcing bars 9.

Here, the main reinforcements 2.6.9, shear reinforcing bars 5.8, connecting bars 1O, etc. that constitute the residential structural members 11, the beam structural members 2, and the joint members 3 are shown in FIGS. 4 and 5, respectively. As shown, the fiber bundle T made of a plurality of continuous fibers 2I bound with a resin material 20 is used as a material and is formed by hardening the fiber bundle T.

Further, to explain in detail by taking the structural member l for a column as an example, as shown in FIG. The fibers 21 of the fiber bundles T are bound together by a resin material 20, with intersections formed at the shear reinforcing bars as shown in FIG.

In addition, at the intersection between the fiber bundles T (the intersection between the main column reinforcement 4 and the shear reinforcement 5), a group of fibers extending in one direction and a group of fibers extending in a direction perpendicular to this, As shown in FIG. 5, it has a cross-sectional shape in which three or more layers are alternately laminated.

In addition, since these basic structures are the same also about the structural member 2 for rice cakes and the joint member 3, description about these is abbreviate|omitted.

As the continuous fibers 21 that form the main body of the column structural member 1, the beam assembly structural member 2, and the joint member 3, glass fibers, carbon fibers, etc., which are lightweight and have high strength, are suitable, but if necessary, other fibers may be used. For example, synthetic resin fibers, ceramic fibers, metal fibers, etc. may be used. Further, these fibers may be used in appropriate combination.

Further, as the resin material 20 for binding each continuous fiber 21 of the fiber bundle T, it is preferable to use vinyl ester resin, etc., which has good adhesiveness to the continuous fibers 21 and has sufficient strength itself. Other resin materials may be used depending on the type of continuous fiber 2I. Examples of other resin materials include unsaturated polyester resin, epoxy resin, and phenol resin.

The ratio of the resin material 20 to the continuous fibers 21 is appropriately determined taking into consideration the type and strength of the continuous edge 411121, the usage form of the structural member 1.2, etc., but for example, if the continuous fibers 21 are If the glass fiber or resin material 20 is vinyl ester resin, the continuous fiber is 2N or the volume ratio is 30.
It is preferable to consider it so that it is about 70%, or about 20 to 60% when the LA fibers 21 are carbon fibers, for example.

If the proportion of continuous edges 1121 is less than the above, the strength of this structural member 1 will be significantly reduced. On the other hand, if the proportion of continuous fibers 21 is increased, a reinforcing member with higher strength can be obtained, but if the proportion of continuous fibers 21 is too high, Therefore, relatively expensive materials such as carbon TA fibers are not preferred from the economic point of view.

In order to form the pillar structural member 1, the flexible structural member 2, and the joint member 3 as described above, for example, in the case of the pillar structural member I, a resin (for example, room temperature curing fluid resin) is used.
The continuous fibers 21 impregnated with resin are hooked onto pins etc. provided at positions corresponding to the upper and lower ends of the main column reinforcement in a so-called one-stroke manner, and the continuous fibers 21 impregnated with resin are placed at positions corresponding to the shear reinforcing bars. I'm going to roll it up.

At these intersections, the fiber groups should be arranged alternately in at least three layers. At this time, continuous edge W12
1 must be given sufficient tension to maintain linearity.

Here, the continuous fibers can of course be fed manually, but a method is adopted in which the continuous fibers are automatically fed by mechanical means that operates based on a program in which the passing order is set in advance.

Further, the distance between the column main reinforcements 4 or the distance between the shear reinforcing bars 5 that constitute the column structural member l is determined depending on the size of the column to be constructed, the required strength, etc., and the continuous fibers 21 are This also includes twisted cords and braided cords.

The flexible structural member 2, the joint member 3, etc. are manufactured in the same manner as the pillar structural member 1.

(11) Installation and Fixation of the Column Structural Member As shown in FIG. 1, the column structural member l assembled by the column main reinforcement 4 and shear reinforcing bars 5 is erected at a predetermined construction position. At this time, since the column structural member 1 is made by hardening continuous fibers 21 with a resin material 20, it is extremely lightweight and easy to handle during transportation, so it can be handled manually without using a crane or the like. It can be constructed with.

(iii) Setting the joint members Next, as shown in Fig. 1, arrange the joint members 3 in the width direction of the column structural member The end) 9a is made to protrude to the opposite side of the column structural member 1 through the mesh of the column main reinforcement 4 and the shear reinforcing bar 5, and is fixed to the column structural member 1.

As a result, the pillar structural member l becomes the pillar structural member! A shisha structure A is set which joins the beam assembly structural members 2 in two axial directions perpendicular to the length direction (see FIG. 2).

At this time (when inserting the joint member 3), the beam connecting main reinforcing bars 9 are formed in a factory with higher precision than a plurality of continuous fibers bound with resin material, so the member position may vary due to manufacturing errors. Since they do not interfere with each other and become a hindrance, the insertion operation can be carried out easily, and the joint member 3 itself has a lightweight structure made by binding continuous fibers 21 with resin material 20. , it has advantages such as being able to perform construction on site easily.

(iv) Construction of flexible and rigid structural members Then, the flexible and rigid structural members 2 are passed between the adjacent column structural members l, and the main beam reinforcements 6 of the flexible structural members 2 are attached to the joint members 3. Join. This joining is performed by the following procedure.

That is, as shown in FIG. 3, etc., the main beam reinforcement 6 of the beam structural member 2, which has ring-shaped shear reinforcing bars 8 fixed to the outer periphery of the upper and lower beam units 2a, is attached to the beam connection main reinforcement 9 of the joint member 3. and bind them together. In addition, the beam connecting main reinforcement 9 of the joint member 3 and the beam main reinforcement 6 of the beam assembly structural member 2
As shown in Fig. 2, the connection form with the connecting main reinforcement 9
The beam main reinforcements 6 are arranged symmetrically so that they are located on the outside of the beam. Note that this connection form is not limited to the illustrated example.

Furthermore, before joining the flexible structural member 2 to the joint member 3, shear reinforcing bars 8 are inserted at a predetermined pitch around the outer periphery of the joint member 3 set on the structural member 1 for columns, as shown in FIG. Shear reinforcing bars 8 to be attached to the lap joint are temporarily attached to both ends of the joint member 3, respectively. This temporarily attached shear reinforcing bar 8 is provided by securing a space in the joint member 3 for temporary placement separately from the lap joint part, and temporarily fixing the shear reinforcing bar 8 in this space.

After joining the Yanagawa structural member 2 and the joint member 3, the shear reinforcing bars 8 temporarily attached to these lap joints are
are moved at predetermined intervals and fixed integrally to the outer periphery of the lap joint.

Note that the beam unit 2a and the joint member 3 or the shear reinforcing bar 8 may be bound together using, for example, a binding iron wire or the like used in conventional reinforcement work.

In this way, after joining the Yanagawa structural member 3 to the residential structural member 1, formwork is assembled on the outside of these members, and then concrete is poured into these formworks, thereby making it possible to cast the columns and beams as one unit. Can be constructed and shaped. In addition, in the above, by reducing the size of the mesh between the main column reinforcement and the shear reinforcing reinforcement 5, it is also possible to pour concrete for the columns of the residential structural member l without using the formwork. .

Further, the on-site assembly work of the Yanagawa structural member 2 may be carried out after the formwork for the columns and beam bottoms has been erected, or may be carried out in parallel with or in advance of the formwork work.

The joint between the column and the beam is constructed as described above, and this construction method allows the joint to be performed extremely easily. In other words, since each member has a lightweight structure made by binding and molding continuous fibers 21 with resin material 20, the work of setting the beam structural member 1 etc. can be done manually without using a crane or the like. This is because it can be easily implemented. Moreover, these connections are a simple operation of inserting the joint member 3 into the column structural member 1 and fixing the flexible structural member 2 via this joint member 3.
Moreover, since the column main reinforcements 4, the beam main reinforcements 6, etc. are all unitized in advance, construction and transportability on site is good, and joining work can be carried out easily.

In addition, each of the above-mentioned members (residential structural member 1, Yanagawa structural member 2,
In the joint member 3), the continuous fibers 21 are made of resin material 20.
Since the structure is coated with , the fibers, which are the main strength members, are highly corrosion resistant and are extremely advantageous as structural materials. Furthermore, since the surface is made of resin as described above, there are also advantages such as the ability to easily roughen the surface to improve adhesion to concrete.

In the above embodiments, the structural member l for columns has been described as having a size corresponding to the height of one floor of the structure, but the structural member l for columns may have a size corresponding to the circumference of two floors or the circumference of two floors. It is also possible to attach the joint member 3 to this pillar structural member l in advance and then erect it. With this configuration, the construction period can be further shortened. .

6 and 7 show another embodiment of the joint construction method of the present invention, in which the procedure for inserting the joint member 3 is changed. That is, the joint members 3 in which the upper and lower beam connecting main reinforcements 9 are integrally connected by the connecting reinforcements IO are inserted from the opposing directions of the residential structural member l as shown by the arrow C, and the insertion ends 9a of the beam connecting main reinforcements 9 are inserted. so as not to be biased towards one side,
This is to prevent the insertion end 9a from coming loose.

In this case, the insertion procedure is, for example, as shown in Fig. 7, insert the two joint members 3 located in the center from the left side of the column structural member i (left side in Fig. 7) as shown by arrow 2. Then, the joint members 3 located at both ends are inserted from the right side as shown by the arrow E, and these are set in the residential structural member l.

According to such a construction method, the inserted end of the joint member 3 set in the residential structural member 1 is less likely to come loose.
It is possible to further facilitate the attachment of the flexible structural member 2 to the joint member 3 and improve its workability.

Moreover, FIGS. 8 and 9 each show a unitized joint member 3 used in the joint construction method of the present invention. In the example shown in FIG.
Assemble unit members 30 of the same configuration with joint members 3 on the sides and the center, insert these from both sides of the column structural member I, as shown in FIG. 7, etc.
It is intended to be integrated into the pillar structural member l.

On the other hand, in the example shown in FIG. 9, there is a unit member 3I in which two sets of joint members 3 are arranged in the center of the ring-shaped shear reinforcement 8, and two sets of joint members 3 on both sides of the ring-shaped shear reinforcement 8. 3, and insert them from both sides of the column structural member I in the same manner as shown in FIG. It is intended to be integrated into the

As described above, by forming a plurality of joint members 3 into a unit, it becomes easier to handle on-site, and the plurality of joint members 3 can be inserted into the column structural member I at the same time, thereby improving the workability. Therefore, it is preferable.

In addition, in the unit examples of the joint members 3 shown in FIGS. 8 and 9, the joint members 3 are constructed of two sets, but the number of joint members 3 is limited to these illustrated examples. It's not something you can do.

Next, an example of the shear reinforcing bar 8 applied to the present invention will be described with reference to FIGS. 1θ (a) to (g). In addition, these can be applied as shear reinforcing bars disposed on the outer peripheries of the structural member I for columns, the structural member 2 for beams, and the joint member 3.

First, in FIG. 1O (a), two auxiliary reinforcements 8c are arranged in the center of the shear reinforcing reinforcement 8 in parallel to the vertical reinforcement 8b extending in the vertical direction. With this configuration, the auxiliary muscle 8
c improves the strength of the shear reinforcing bars 8, and also makes it possible to assemble the main beam reinforcements 6, etc. along the auxiliary reinforcements 8c, making it easier to set the reinforcement positions of the main beam reinforcements 6, etc., and improve assembly accuracy. Further improvements can be made.

In addition, in FIG. 10 (B), a protrusion 8 d that protrudes inward is provided at the position of the auxiliary reinforcement 8 c shown in FIG. It is something that With such a configuration, setting of reinforcement positions becomes easy and assembly accuracy can be improved.

Next, in FIG. 10(C), a protrusion 8a is provided at the lower end of the shear reinforcing bar 8 shown in FIG. ,
A protrusion 8e extending in the horizontal direction is provided on the side of the vertical reinforcement 8b,
These protrusions 8a and 8e act as spacers on the lower surface of the beam to maintain the concrete coating thickness.

In addition, Fig. 1θ (d) shows a diagram in which a protrusion 8d for setting the reinforcement position is provided at the position of the auxiliary reinforcement 8c instead of the auxiliary reinforcement 8c of the shear reinforcing bar 8 shown in Fig. 10 (c). be. Even with such a configuration, the same effects as described above can be achieved.

On the other hand, in FIG. 10(E), the protruding portion 8a located at the center of the lower end of the shear reinforcing bar 8 shown in FIG. 10(C) is omitted. It is possible to achieve the same effect as the shear reinforcing bar 8 shown in .

In addition, in FIG. 10(f), the protruding portion 8a located at the center of the lower end of the shear reinforcing bar 8 shown in FIG. 10(d) is omitted, and the same effect can be achieved even with such a configuration. be able to.

In Fig. 1θ (g), there are protrusions 8 for setting the concrete coating thickness at the four corners of the shear reinforcing bars 8 with the auxiliary bars 8c.
a and 8e, respectively, and with such a configuration, the applicability of the crosspiece structural member l as a shear reinforcing bar can be improved.

In each of the above embodiments, the pillar structural member 1, the beam structural member 2, the joint member 3, etc. were formed of fibers hardened with a resin material, but in the present invention, these materials are the same as those of the embodiments. (For example, each component (column main reinforcement 4, shear reinforcing reinforcement 5, etc.) may be composed of reinforcing bars or the like.

Similarly, the structural member for the beam and the joint member may also be constructed using reinforcing bars.

Furthermore, the joint member is inserted into a mesh of column main reinforcements and shear reinforcing bars, and a pair of upper and lower beam connection main reinforcements are connected to the upper and lower beam main reinforcements of the flexible structural member, and one side of these upper and lower beam connection main reinforcements. connecting reinforcements that are provided only in the column and integrating the upper and lower beam connection main reinforcements; With this structure, it is possible to easily and firmly join the beam structural member to the column structural member with good construction accuracy, and the construction work can be easily carried out on site. Furthermore, it becomes possible to arrange shear reinforcing bars within the joint part of the column, resulting in a more favorable structure from a design perspective.In addition, in the construction method of the second invention, for columns consisting of column main reinforcement and 4TI shear reinforcing bars, It consists of the process of assembling structural members in advance and erecting them at the construction location, a pair of upper and lower beam connecting main reinforcements that extend in the length direction of the beam, and a connecting reinforcement that integrates these pairs of upper and lower beam connecting main reinforcements.
