Description

The present invention, precast reinforced concrete (as appropriate hereinafter referred PCa.) Belongs to the technical field of junction structure of the beam members to each other.

Conventionally, junction structure between PCa beam member, FIG. 25A, as illustrated in B, opposite PCa beam members a, rebar b projecting from a, by joining b together out the rear to the joint concrete Generally, post-construction work (not shown) such as installation work is performed. Incidentally, the method of joining (joining) the reinforcing bars b and b includes a pressure welding joint method, a welded joint method, a mechanical joint method, and the like. From this point of view, it is common to secure the interval L between the PCa beam members a and a by about 150 cm (for example, FIG. 1 of Patent Document 1, FIG. 4 of Patent Document 2, and Patent Document 3). (See FIG. 3). Incidentally, FIGS. 25A and 25B show an example in which a plurality of column main bars c are protruded above the PCa column member e and constructed in a structural form (so-called skewering method or the like). The symbol d in the figure indicates a support work.

  However, since the conventional method of joining the PCa beam members a and a needs to secure an interval between the PCa beam members a and a of about 150 cm from the viewpoint of work, the joint between the rebars b and b is necessary. After completion of the work, in order to fill the gap between the beam members a, a, a concrete placement mold is placed in the vicinity of the joint portion between the PCa beam members a, a facing each other, and the concrete is cast. It was necessary to perform a large-scale post-construction work for integrating the joint portion between the reinforcing bars b and b and the PCa beam members a and a. Therefore, there was a problem that the construction period was prolonged and it was too uneconomical.

  By the way, FIG. 26 has shown the joining method from which PCa beam members a and a differ. In this technique, a sleeve joint f is embedded horizontally in one (left side in the illustrated example) PCa beam member a, and a reinforcing bar b is projected horizontally in the other (right side in the illustrated example) PCa beam member a. The other PCa beam member a is moved in the horizontal direction (left direction in the illustrated example), the rebar b is inserted into the sleeve joint f and stored, and the joint portion is filled with grout to form the PCa beam member. The joining operation | movement of a and a is performed (for example, refer FIG. 3 of patent document 4).

  According to the technique according to FIG. 26, the PCa beam members a and a can be joined to each other by an operation of filling the joint portion (gap) with grout with almost no space between the PCa beam members a and a. Therefore, a large-scale post-work such as placing a concrete casting form in the vicinity of the joint portion between the PCa beam members a and a facing each other and placing concrete is not necessary. Compared to this, post-construction can be simplified and the construction period can be shortened.

If one of the PCa beam members a is not positioned, the other PCa beam member a is positioned. Since the PCa beam member a cannot be positioned and is greatly restricted by the construction procedure, it also contributes to the lengthening of the construction period.

Incidentally, reference numeral 10 in FIG. 1 denotes a U-shaped reinforcing bar bent in the horizontal direction at a required length, reference numeral 11 denotes a staggered bar, and reference numeral 12 denotes a reinforcing bar.

In the present reference example, four through holes 2 are provided in each PCa beam member 1, but the present invention is not limited to this. It can be appropriately increased or decreased according to the designed strength. By the way, referring to FIGS. 1B and 1C, the through hole 2 according to this reference example is provided substantially in parallel with the through holes 2 and 2 that are inclined from the upper right to the lower left being inclined to the right, and is inclined from the upper left to the lower right. The through-holes 2 and 2 are biased to the left side and provided substantially in parallel so that the through-holes 2 do not interfere with each other. However, the position of the through-holes 2 is not limited to this. is there.

The through hole 2 is formed by embedding a sheath tube (not shown), but the method of forming the through hole is not particularly limited to embedding the sheath tube, but a concrete hole. It may be formed. By the way, the concrete hole is formed by a method in which the air tube is installed at a predetermined position (corresponding to a through-hole and a non-through-hole) before placing the concrete, and after placing the concrete, the air is extracted and the tube is pulled out. der Ru. The same technical idea applies to the following embodiments.

The connecting member 4 is preferably a rod-shaped reinforcing bar (including deformed reinforcing bars such as screwed reinforcing bars and PC steel bars; the same applies hereinafter). The connecting member 4 is threaded at both ends, and is inserted into a series of through holes 2 and 2 formed by the opposing PCa beam members 1 and 1, and both ends thereof are inserted into the notches 5 with nuts 6. By fixing to each other, both the PCa beam members 1 and 1 are surely positioned. The connection member 4 according to this reference example is implemented with a total of four according to the number of the through holes 2, but the number of the through holes 2 and the size of the beam member 1 to be used (especially the width dimension). , And can be appropriately increased or decreased according to the required design strength. It should be noted that the required length of the connecting member 4 is such that the both end portions are exposed to the notch portion 5 in a state where the connecting member 4 is inserted into the through hole 2 and positioned.

The notch portion 5 is necessary when the connecting member 4 is fixed with the nut 6, but is particularly necessary when fixed only with the hardener 7 as shown in FIGS. 8 and 13. is not.
There are various methods for fixing the connecting member 4 with the fixing device 6. Of course, there is a method for fixing the screw by screwing the nut 6 when the end of the connecting member 4 is threaded. In the case where the connecting member 4 is implemented by the threaded joint reinforcing bar 4, there is a method of fixing by screwing a nut directly into the threaded joint. The same technical idea applies to the following embodiments.

  Thus, the connecting member 4 is inserted into the through-holes 2 between the beam members 1 and 1 positioned in the opposing arrangement, and both end portions of the connecting member 4 are fixed in the notch portion 5 by the nuts 6 and 6. The through hole 2 is filled with a hardening material 7 such as grout through the filling holes 8 provided at both ends of the through hole 2 and the notch 5 is filled with a hardening material 7 such as concrete. By doing so, the connecting member 4 is firmly fixed and the precast reinforced concrete beam members 1 and 1 are joined together (see FIG. 1B). The filling operation of the notch portion 5 provided below the PCa beam members 1 and 1 is performed by providing a simple formwork material (not shown) such as a steel plate in order to prevent the hardening material 7 from leaking. Note that.

  Therefore, according to the joining method of the precast reinforced concrete beam members and the joining structure constructed by the same method, a structure type in which a plurality of column main bars protrude below the PCa column member (so-called reverse skewering method, reverse insertion column, figure 26), it can be particularly preferably applied to a structure type in which a plurality of column main bars protrude above the PCa column member (so-called skewering method, see FIGS. 25A and B). In joining them together, the PCa beam member 1 can be positioned and positioned in an opposing arrangement without moving the PCa beam member 1 in the horizontal direction, so the use of a simple formwork material such as a steel plate, Further, the PCa beam members 1 and 1 can be reliably joined together by filling with a small amount of a hardening material 7 such as grout. Therefore, large-scale post-construction can be dramatically simplified, and the construction period can be greatly shortened. Therefore, the construction and economy are excellent.

Further, the coupling member 4 of the PC steel rod or round steel, screw clause rebar, carried by a bolt, when carried out Prestressing Impact (air) wrench when tightening the nuts 6, the operation and effect In addition, it is possible to improve the bending crack strength at the joint between the PCa beam members 1 and 1. In addition, when implementing by introducing a prestress, it can also carry out by an unbond, However, Filling and implementing hardening materials 7, such as grout, has a rust prevention effect and improves integrated strength. Therefore, it is preferable.

It should be noted that the required length of the connecting member 4 is such that the both end portions are exposed to the notch portion 5 in a state where the connecting member 4 is inserted into the through hole 2 and positioned.

  Thus, the connecting member 4 is inserted into the through-holes 2 between the beam members 1 and 1 positioned in the opposing arrangement, and both end portions of the connecting member 4 are fixed in the notch portion 5 by the nuts 6 and 6. The through hole 2 is filled with a hardener 7 such as grout through filling holes (not shown) provided at both ends of the through hole 2 and the notch 5 is hardened with concrete or the like. 7 is filled, the connecting member 4 is firmly fixed, and the precast reinforced concrete beam members 1 and 1 are joined together (see FIG. 4B). The filling operation of the notch portion 5 provided below the PCa beam members 1 and 1 is performed by providing a simple formwork material (not shown) such as a steel plate in order to prevent the hardening material 7 from leaking. Note that.

By filling the hardening material 7, the PCa beam members 1, 1 can be reliably joined together. Therefore, large-scale post-construction can be dramatically simplified, and the construction period can be greatly shortened. Therefore, the construction and economy are excellent.

Incidentally, FIG. 7 and FIG. 8 show variations of the joint structure between the PCa beam members according to the first embodiment. FIG. 7 shows an embodiment in which the curvature of the shape of the through-hole 2 and the connecting member 4 is reduced and the number is doubled as compared with the joining structure according to FIGS. 4 to 6. 7 is an embodiment in which the connecting member 4 is fixed only by a hardening material 7 such as grout without using a fixing tool such as a nut 6. For even these variations, the same effects as the operation and effect according to the first embodiment mentioned above.

Can be integrally joined to each other. Therefore, large-scale post-construction can be dramatically simplified, and the construction period can be greatly shortened. Therefore, the construction and economy are excellent.

In addition, since the joining structure according to the second embodiment can perform the joining work of the PCa beam members 1 and 1 from only one side, it is suitable for the joining structure of the beam members used for the construction of the veranda or the balcony. There are advantages that can be implemented.

FIG. 12 shows a joint structure between PCa beam members 1 and 1 according to claim 3 . In this joint structure, the end portions of the beam member 1 are each provided with a total of eight through-holes 2 in a balanced manner in the upper part and four in the lower part in a balanced manner when close to the contact state.

Further, in the joint structure according to FIG. 12, when the beam members 1 and 1 are brought into a substantially abutting state, the beam members 1 and 1 are horizontally moved from both side surfaces of the one side beam member 1 to both side surfaces of the other side beam member 1. The through-holes 2 that fold through and penetrate in the direction are formed in a symmetrical arrangement when viewed from the plane direction (see FIG. 12A), and the through-holes 2 have a curved shape that matches the shape of the through-holes 2. The connecting member 4 is inserted and positioned, and the hardened material 7 is filled in the through-hole 2 so that the precast reinforced concrete beam members 1 and 1 are joined together (invention of claim 3 ).

Furthermore, in the joining structure according to FIG. 12, notches 5 are formed at positions corresponding to the ends of the connecting member 4 in the beam member 1, that is, on both side surfaces of the PCa beam member 1, respectively. It is positioned by fixing in the notch 5 with a fixing tool such as a nut 6 (invention of claim 6 ). Incidentally, reference numeral 10 in FIG. 12 denotes a U-shaped reinforcing bar bent in the horizontal direction at a required length, and reference numeral 11 denotes a staggered bar.

  In the present embodiment, eight through-holes 2 are provided in each PCa beam member 1, but the present invention is not limited to this, and the size (particularly the width) of the PCa beam member 1 to be used and the requirements are not limited thereto. It can be appropriately increased or decreased according to the designed strength. Incidentally, the through holes 2 according to the present embodiment are concentrated and provided in the upper part and the lower part (see FIG. 12B), but the arrangement position is of course not limited to this.

  The connecting member 4 is preferably a curved reinforcing bar bent so as to match the shape of the through hole 2. The connecting member 4 is threaded at both ends, and is inserted into a series of through holes 2 and 2 formed by the opposing PCa beam members 1 and 1, and both ends thereof are inserted into the notches 5 with nuts 6. By fixing to each other, both the PCa beam members 1 and 1 are surely positioned.

It should be noted that the required length of the connecting member 4 is such that the both end portions are exposed to the notch portion 5 in a state where the connecting member 4 is inserted into the through hole 2 and positioned.

  Thus, the connecting member 4 is inserted into the through-holes 2 between the beam members 1 and 1 positioned in the opposing arrangement, and both end portions of the connecting member 4 are fixed in the notch portion 5 by the nuts 6 and 6. The through hole 2 is filled with a hardener 7 such as grout through filling holes (not shown) provided at both ends of the through hole 2 and the notch 5 is hardened with concrete or the like. 7 is filled, the connecting member 4 is firmly fixed, and the precast reinforced concrete beam members 1 and 1 are joined together (see FIG. 12A). It should be noted that the filling operation of the cutout portion 5 is performed by providing a simple formwork material (not shown) formed of a steel plate or the like in order to prevent the hardening material 7 from leaking.

Therefore, according to the contact Go構 granulation of the precast reinforced concrete beam members to each other, achieves substantially the same effects as the first and second embodiments. That is, not only the structural form in which a plurality of column main bars protrude below the PCa column member (so-called reverse skewering method, reverse insertion column, see FIG. 26), but also the structure in which a plurality of column main bars protrude above the PCa column member. This method can be particularly preferably applied to the type (so-called skewering method, see FIGS. 25A and B), and when joining the PCa beam members 1 and 1, a slight gap is required without moving the PCa beam member 1 in the horizontal direction. (2cm) can be provided and positioned facing each other, so the PCa beam members 1 and 1 can be securely connected to each other by using a simple formwork material such as a steel plate and filling with a small amount of hardening material 7 such as grout. Can be integrally joined to each other. Therefore, large-scale post-construction can be dramatically simplified, and the construction period can be greatly shortened. Therefore, the construction and economy are excellent.

Incidentally, FIG. 13 shows a variation of the joint structure according to the third embodiment. The joining structure according to FIG. 13 is an embodiment in which the connecting member 4 is fixed only by a hardening material 7 such as grout without using a fixing tool such as a nut 6 as compared with the joining structure according to FIG. is there. The bonding structure according to FIG. 13 also has substantially the same operational effects.

14 to 16 show a joint structure between PCa beam members 1 and 1 according to claim 4 .
In this joining structure, two end holes 2 and two non-through holes 2 are provided at the end portions of the beam member 1 so as to be close to the contact state. There are a total of four connecting members 4 which are provided in an opposed arrangement so as to be almost in contact with each other, and which are connected to the four non-through holes 2 which become non-through holes 2 when they coincide with each other across the two beam members 1 and 1 from the outside. are present inserted is positioned, the preferred the cured material 7 is filled precast reinforced concrete beam members 1 with each other to bond to each non-through holes 2 that are integrally joined.

14 to 16, when the beam members 1 and 1 are brought close to contact with each other, they are inclined from the upper surface of the beam member 1 on one side toward the beam member on the other side. A non-through hole 2 that stops is provided, and a joint 3 in which an end of a reinforcing bar 9 embedded in the beam member 1 on the other side is inserted in the dead end of the non-through hole 2 is inclined in the vertical direction. The non-through hole 2, the joint 3, and the reinforcing bar 9 are formed in a symmetrical arrangement when viewed from the front (see FIG. 14B), and a rod-like connecting member 4 is provided in the non-through hole 2. Inserted until the tip reaches the inside of the joint 3, is positioned so as to face the end of the rebar 9 in the joint 3, and the non-through hole 2 is filled with a hardening material 7 to be precast reinforced concrete beam member 1, 1 are integrally joined (invention of claim 4 ).

Further, in the joining structure according to FIGS. 14 to 16, a notch portion 5 is formed at a position corresponding to the end portion of the connecting member 4 in the beam member 1, that is, at the upper surface portion of the PCa beam member 1. The end portion is positioned by being fixed in the notch portion 5 with a nut 6 or a fixing tool such as a mechanical fixing tool (the invention according to claim 6 ). Incidentally, reference numeral 10 in FIG. 14 denotes a U-shaped reinforcing bar bent in the horizontal direction at a required length, reference numeral 11 denotes a staggered bar, and reference numeral 12 denotes a reinforcing bar.

  In the present embodiment, a total of four through holes 2 and non-through holes 2 are provided in each PCa beam member 1, but the present invention is not limited to this, and the size of the PCa beam member 1 to be used is not limited to this. Depending on (especially the width dimension) and the required design strength, for example, as shown in FIGS. Incidentally, the non-through hole 2 formed in a series by matching the through hole 2 and the non-through hole 2 according to the present embodiment is a non-through hole 2 inclined from the upper right to the lower left, referring to FIGS. The non-through holes 2 that are biased to the right and provided substantially in parallel, and that are inclined to the left from the upper left to the left are provided substantially in parallel so that the non-through holes 2 do not interfere with each other. Of course, the position of the through hole 2 is not limited to this.

The connecting member 4 is preferably a rod-shaped reinforcing bar. The connecting member 4 is threaded at the end exposed on the notch 5 and is inserted into a series of non-through holes 2 formed by the opposing PCa beam members 1, 1 and its tip Is inserted into the joint 3 and positioned opposite to the end of the embedded reinforcing bar 9, and the base end is fixed in the notch 5 with the nut 6. The connecting member 4 according to the present embodiment is implemented in a total of four according to the number of non-through holes 2, but the number of the non-through holes 2 and the size of the beam member 1 to be used (especially the width) It can be appropriately increased or decreased according to the required design strength (see FIGS. 17 to 19). It should be noted that the required length of the connecting member 4 is such that the base end portion is exposed to the notch portion 5 in a state where the distal end portion is inserted into the joint 3 and positioned.
In addition, although the coupling 3 which concerns on a present Example is implemented with the sleeve coupling 3, it is not limited to this, It can implement similarly also with the screw-type coupling by which the inner wall surface was threaded.

  Thus, the connecting member 4 is inserted into each non-through hole 2 between the beam members 1, 1 positioned in an opposing arrangement, and the base end portion of the connecting member 4 is fixed in the notch 5 by the nut 6. In this state, the non-through hole 2 and the sleeve joint 3 are filled with a hardening material 7 such as grout through a filling hole (not shown) provided in the through hole 2, and the notch 5 is filled with concrete or the like. By filling the hardener 7, the connecting member 4 is firmly fixed and the precast reinforced concrete beam members 1 and 1 are joined together (see FIG. 14B).

  In addition, since all the filling work of the hardening material 7 is sufficient only from the upper side, it can be implemented with a simple formwork material. When the threaded joint is used instead of the sleeve joint 3, the end of the reinforcing bar 9 and the tip of the connecting member 4 are connected by screwing in from both sides of the threaded joint. It is not necessary to fill the hard joint 7 such as grout inside the type joint. The notch 5 is necessary when the connecting member 4 is fixed with the nut 6, but is not particularly required when the connecting member 4 is fixed only with the curing material 7.

Furthermore, the shape and installation site of the joint 3 are not limited to FIGS. 14 to 16 and FIGS. 17 to 19, and are bent to the sites shown in FIGS. 20A and 20B, respectively. Can also be implemented. 20A and 20B, in the embodiments according to FIGS. 14 to 16 and FIGS. 17 to 19, one end portion of the reinforcing bar 9 is bent and formed to rise upward. On the other hand, there is an advantage that the rod-shaped reinforcing bar 9 can be used without any processing.
By the way, in the case where the end of the connecting member 4 exposed to the outside is fixed with a fixing tool 6 such as a nut, the PCa beam members 1 and 1 exhibit the necessary strength for structural design. It is not necessary to fill the entire through hole 2 with the hardened material 7 on the condition that the joint can be firmly joined.

Therefore, according to the contact Go構 granulation of the precast reinforced concrete beam members to each other, it achieves substantially the same effects as in Example 1 to Example 3. That is, not only the structural form in which a plurality of column main bars protrude below the PCa column member (so-called reverse skewering method, reverse insertion column, see FIG. 26), but also a structure in which a plurality of column main bars protrude above the PCa column member. This method can be particularly preferably applied to the type (so-called skewering method, see FIGS. 25A and B), and when joining the PCa beam members 1 and 1, a slight gap is required without moving the PCa beam member 1 in the horizontal direction. (2cm) can be provided and positioned facing each other, so the PCa beam members 1 and 1 can be securely connected to each other by using a simple formwork material such as a steel plate and filling with a small amount of hardening material 7 such as grout. Can be integrally joined to each other. Therefore, large-scale post-construction can be dramatically simplified, and the construction period can be greatly shortened. Therefore, the construction and economy are excellent.

21 to 23 show a joint structure between PCa beam members 1 and 1 according to claim 5 .
In this joint structure, the end portions of the beam member 1 are each provided with three through-holes 2 and three non-through-holes 2 that coincide with each other when the beam members 1 are almost brought into contact with each other. There are a total of 6 connecting members 4 which are provided in an opposing arrangement so as to be almost in contact with each other, and which are connected to the six non-through holes 2 which become the non-through holes 2 when they coincide with each other across the two beam members 1 and 1 from the outside. are present inserted is positioned, the preferred the cured material 7 is filled precast reinforced concrete beam members 1 with each other to bond to each non-through holes 2 that are integrally joined.

A non-through hole 2 is provided, and a joint 3 into which an end of a reinforcing bar 9 embedded in the beam member 1 on the other side is inserted in the dead end of the non-through hole 2 is inclined in the horizontal direction. The non-through hole 2, the joint 3, and the reinforcing bar 9 are formed in a symmetrical arrangement when viewed from the plane direction (see FIG. 21A), and a rod-like connecting member 4 is formed in the non-through hole 2. It is inserted until its tip reaches the inside of the joint 3, is positioned so as to face the end of the rebar 9 in the joint 3, and the non-through hole 2 is filled with a hardening material 7 to be precast reinforced concrete beam members 1 to each other are integrally joined (the invention described in claim 5)

Further, in the joining structure according to FIGS. 21 to 23, a notch portion 5 is formed at a position corresponding to the end portion of the connecting member 4 in the beam member 1, and the end portion is a nut 6 or a mechanical joint. It is positioned by fixing in the notch 5 with a fixing tool such as the above (invention of claim 6 ). Incidentally, reference numeral 10 in FIG. 21 denotes a U-shaped reinforcing bar which is bent in the vertical direction with a required length and bent in the horizontal direction so as to avoid the notch 5, and reference numeral 11 denotes a staggered bar. Show.

  In this embodiment, the number of the through-holes 2 and the non-through-holes 2 is set such that a total of six through holes 2 are arranged substantially on the vertical line at the center of each PCa beam member 1 as shown in FIG. However, the present invention is not limited to this, and can be appropriately increased or decreased according to the size (particularly the width) of the PCa beam member 1 to be used and the required design strength.

The connecting member 4 is preferably a short bar-shaped reinforcing bar. The connecting member 4 is threaded at the end exposed on the notch 5 and is inserted into a series of non-through holes 2 formed by the opposing PCa beam members 1, 1 and its tip Is inserted into the joint 3 and positioned opposite to the end of the embedded reinforcing bar 9, and its base end is fixed to the notch 5 with the nut 6. The connection member 4 according to the present embodiment is implemented in a total of six according to the number of the non-through holes 2, but the number of the non-through holes 2 and the size of the beam member 1 to be used (especially the width) Dimension) and can be appropriately increased or decreased according to the required design strength. It should be noted that the required length of the connecting member 4 is such that the base end portion is exposed to the notch portion 5 in a state where the distal end portion is inserted into the joint 3 and positioned.
In addition, although the coupling 3 which concerns on a present Example is implemented with the sleeve coupling 3, it is not limited to this, It can implement similarly also with the screw-type coupling by which the inner wall surface was threaded.

  Thus, the connecting member 4 is inserted into each of the non-through holes 2 between the beam members 1 and 1 positioned in an opposing arrangement, and the base end of the connecting member 4 is inserted into the notch 5 by the nut 6. In a fixed state, the inside of the non-through hole 2 and the sleeve joint 3 is filled with a hardening material 7 such as grout through a filling hole (not shown) provided in the through hole 2, and the inside of the notch 5 When the hardener 7 such as concrete is filled, the connecting member 4 is firmly fixed and the precast reinforced concrete beam members 1 and 1 are joined together (see FIG. 21A). It should be noted that the filling operation of the cutout portion 5 is performed by providing a simple formwork material (not shown) formed of a steel plate or the like in order to prevent the hardening material 7 from leaking.

  When the threaded joint is used instead of the sleeve joint 3, the end of the reinforcing bar 9 and the tip of the connecting member 4 are connected by screwing in from both sides of the threaded joint. It is not necessary to fill the hardened material 7 such as grout inside the threaded joint. The notch 5 is necessary when the connecting member 4 is fixed with the nut 6, but is not particularly required when the connecting member 4 is fixed only with the curing material 7.

Furthermore, the shape of the joint 3 and the installation site are not limited to those shown in FIGS. 21 to 23, and the joint 3 can be implemented in a bent shape at the site shown in FIG. According to the embodiment according to FIG. 24, in the embodiment according to FIGS. 21 to 23, one end portion of the reinforcing bar 9 has to be bent into an inclined shape, whereas the rod shape is not processed. There exists an advantage which can be implemented with the rebar 9 as it is.
By the way, in the case where the end of the connecting member 4 exposed to the outside is fixed with a fixing tool 6 such as a nut, the PCa beam members 1 and 1 exhibit the necessary strength for structural design. It is not necessary to fill the entire through hole 2 with the hardened material 7 on the condition that the joint can be firmly joined.

Therefore, according to the contact Go構 granulation of the precast reinforced concrete beam members to each other, it achieves substantially the same effects as in Example 1 to Example 4. That is, not only the structural form in which a plurality of column main bars protrude below the PCa column member (so-called reverse skewering method, reverse insertion column, see FIG. 26), but also the structure in which a plurality of column main bars protrude above the PCa column member. This method can be particularly preferably applied to the type (so-called skewering method, see FIGS. 25A and B), and when joining the PCa beam members 1 and 1, a slight gap is required without moving the PCa beam member 1 in the horizontal direction. (2cm) can be provided and positioned facing each other, so the PCa beam members 1 and 1 can be securely connected to each other by using a simple formwork material such as a steel plate and filling with a small amount of hardening material 7 such as grout. Can be integrally joined to each other. Therefore, large-scale post-construction can be dramatically simplified, and the construction period can be greatly shortened. Therefore, the construction and economy are excellent.
In addition, since the joining structure according to the fifth embodiment can perform the joining work of the PCa beam members 1 and 1 from only one side surface in the same manner as the joining structure according to the second embodiment, the construction of the veranda or the balcony is possible. There is an advantage that it can be suitably implemented in a joint structure between beam members used in the above.

  The embodiments have been described with reference to the drawings. However, the present invention is not limited to the illustrated embodiments, and design modifications and application variations that are usually made by those skilled in the art are within the scope of the technical idea of the invention. Note that it includes the range.

For example, in an embodiment in which both ends of the connecting member 4 are fixed with a fixing tool such as a nut ( see FIGS. 4, 7, 9, and 12), the PCa exhibits a required strength in structural design. On the condition that the beam members 1 and 1 can be firmly bonded to each other, there may be a case where the through hole 2 can be carried out without being filled with a hardening material 7 such as grout.
