A polygonal opening 10 is provided on the upper surface 13 of the upper beam 3 on the upper end of the column 2 of the unit structure 1 on the lower floor and on the axis of the column 2. A rectangular (polygonal) opening 11 is provided at the lower end portion of the column 52 of the upper floor unit structure 50 and on the lower surface 55 of the lower beam 54. Each opening part 10 and 11 is the same shape, and it is comprised so that it may become a positional relationship which mutually agree | coincides and aligns.

And a connecting member (positioning protrusion) 17 having a quadrangular (polygonal) cross-sectional shape to be fitted to the portions 10 and 11.

Through holes 13a, 55a, and 18a for inserting bolts are formed in the upper surface 13 of the upper beam 3, the lower surface of the lower beam 54, and the substrate 18 of the connector 15 so as to be aligned with each other.
After the positioning of the upper beam 3, the connector 15, and the lower beam 54 is completed, the bolt 19 is inserted into each of the through holes 13 a, 55 a, 18 a and fastened with nuts to fix the unit structure 1 on the lower floor. On the other hand, the unit structure 50 on the upper floor can be connected via the connector 15.

In the embodiment of the present invention, the horizontal positioning of the unit structures on the upper and lower floors is performed by the connecting members 17 each having a polygonal cross-section, and the openings 10 and 11 into which the connecting members 17 are fitted in alignment. Therefore, the horizontal direction of the unit structure on the upper and lower floors can be uniquely positioned without rotating the connector 15 or the unit structure.
In the above embodiment, the openings 10 and 11 are provided in the upper beam 3 of the lower floor unit structure and the lower beam 54 of the upper floor unit structure, respectively. The upper end surface and the lower end surface of the column 52 of the upper floor unit structure 50 are each provided with an opening having a polygonal cross section (similar to the planar shape of the connecting member), and each connecting member 17 of the connecting tool is provided in each opening. You may comprise so that it may insert. In short, the openings 10 and 11 are preferably provided at portions corresponding to the upper part of the pillar 2 and the lower part of the pillar 52.

Next, FIGS. 4A and 4B are a front longitudinal sectional view and a plan view of the connection structure, and FIGS. 5A and 5B are a front view and a plan view showing the configuration of the connection tool. It is.
Here, an example of a specific connection structure constructed using the principle of the connection structure shown in FIGS. 2 and 3 will be described. In addition, the same code | symbol is attached | subjected and demonstrated to the same part as FIG.
In the connection structure A according to this specific example, the connection tool 15 includes a substrate 18 having an L-shaped planar shape as shown in the figure, and a connection member 17 that protrudes from opposite positions on both surfaces of the substrate 18. doing. The connecting member 17 is a rectangular cylindrical body having an inside that penetrates in the axial direction, but may have a dense structure.

The upper end surface (upper surface of the beam 3) of the column 2 of the unit structure 1 on the lower floor is similar to the planar shape of the connecting member 17 (contour shape viewed from one end in the axial direction) and is more than the contour of the connecting member. An opening 10 having a slightly large opening area is formed so as to penetrate therethrough, and the lower end surface of the column 52 (the lower surface of the beam 54) of the upper unit structure 50 is similar to the planar shape of the connecting member 17 and the connecting member. A slightly larger opening 11 is formed through.
When the upper and lower openings 10 and 11 are connected using the connecting tool 15, one connecting member 17 of the connecting tool 15 is inserted into each opening 10 exposed on the upper surface of the unit structure 1 on the lower floor. The lower surface of the substrate 18 is placed on the upper surface of the beam 3 in the fitted state. In this state, the through holes 13a, 5 5 a, it is not necessary to temporarily fix the bolts 18a. Next, the unit structure 50 on the upper floor is lifted using a crane or the like and placed on the unit structure 1. At this time, alignment is performed so that the upper connecting member 17 of each connector is fitted in each opening 11 on the lower surface of the unit structure 50. Then, through holes 13a, 5 5 a, by which is passed through the bolt into 18a fastened by a nut, connection between the two units structure is completed.

  According to this embodiment, since it is not necessary to temporarily fix the connector 15 on the unit structure 1 using a bolt etc., an assembly man-hour can be reduced. In addition, when connecting the upper and lower openings using a special joint member, it is necessary to fasten the joint member between the openings via a large work window formed in a proper position of a column or beam. In the present invention, since the temporary fixing and positioning are completed simply by sandwiching the connecting tool between the upper and lower columns (between beams), the number of steps can be reduced. In addition, it is possible to eliminate the decrease in strength and the increase in the number of column processing operations caused by forming work windows on the columns.

Moreover, although the cross-sectional shape of the direction orthogonal to the axial direction was demonstrated using the thing of a square as each connection member 17 in the said embodiment example, it is not limited to this, A cross-sectional shape (plane shape) is It can be a triangle or other polygon. Further, by providing openings similar to the planar shape of each connecting member in the upper beam 3 and the lower beam 54, or the upper end of the column 2 and the lower end of the column 52, the connecting tool 15 does not rotate and the upper and lower floors are not rotated. The unit structure can be positioned in the horizontal direction.
Moreover, it is also possible to make it easy to insert into the opening part by chamfering the periphery of the front end surface of each connecting member 17. From this viewpoint, as an extreme example, the front shape of the connecting member may be a polygonal cone, a cone (including a cone shape having a flat surface at the tip surface), and the like.
Further, the planar shape of the connecting member 17 does not necessarily have to be a polygonal shape, and even if it is a cylindrical shape or an elliptical cylindrical shape, it opens at the outer peripheral surface when fitted into an opening having a similar opening shape. This is because the horizontal positioning can be sufficiently achieved if the inner peripheral edge can be engaged. For example, when the connecting member has a cylindrical shape, the opening shape of the opening is circular, so that the connecting member can be rotated within the opening, but the positioning of the connecting member is within the lower opening 10. Therefore, it is easy to align the upper opening 11 on the unit structure side and to fit the connecting member. The opening shape of the opening is a contour shape of the inner periphery of the opening viewed from one end side of the axis passing through the center of the opening.

2 and 3 show a dense configuration example as the connecting member 17, but a hollow cylindrical body is formed by forming a hole penetrating in the connecting member 17 in the axial direction as shown in FIGS. Also good.
Further, the connecting member 17 may protrude only on one surface of the substrate 18. That is, for example, when the connecting tool 15 having the connecting member 17 protruding only on the upper surface of the substrate 18 is used, the lower surface of the substrate 18 is bolted to the upper surface of the lower unit structure. At this time, since the single connecting member 17 protruding upward is in a positional relationship with the opening 11 on the lower surface of the unit structure 50 on the upper floor to be stacked, the unit structure 50 can be united with good consistency. By stacking on the structure 1, the connecting member 17 can be fitted into the opening 11. In addition, the structure which provides the connection member 17 only in one side of a board | substrate is applicable to all the following connection structures.
When the connecting member 17 is provided only on one surface of the substrate as described above, the opening into which the connecting member is fitted may be provided only on the lower surface of the unit structure 50 on the upper floor.

As described above, according to the connection structure A of the present invention, the openings can be positioned by the connection tool 15, so that temporary fixing using a bolt or the like is not necessary. Conventionally, when joining the upper part of the pillar 2 and the lower part of the pillar 52, it is necessary to perform work such as bolt tightening inside each pillar, and a working window is opened on the side surface of one of the pillars. However, since such a window has a relatively large opening, it causes a reduction in the strength of the column and an increase in the number of processing steps when manufacturing the column.
On the other hand, in the present invention, the openings are positioned by the connecting member 17 simply by sandwiching the connecting tool between the opposing surfaces of the columns, so that there is no need for a bolt fastening operation or the like inside the column through the window. , Man-hours can be reduced, and the strength of columns can be reduced and the number of processing steps can be eliminated. Moreover, since no window is formed, the strength of the pillar can be increased and the number of manufacturing steps can be reduced.

Moreover, although the example which applied this invention to the connection structure in the case of stacking the upper unit structure on the lower unit structure in the said embodiment was shown, this invention is a unit connected horizontally. The present invention can also be applied to the joint surface of the structure. That is, in this case, both unit structures are formed by forming openings on the opposite end faces of two unit structures adjacent to each other in the lateral direction or on the end faces of the beams, and mounting the connecting tool 15 in the openings. The body can be easily positioned to eliminate lateral displacement.
That is, FIG. 6 is a cross-sectional view of a main part showing a configuration in which two unit structures 1A and 1B are connected by the connecting tool 15 in a state where they are adjacent in the horizontal direction. In addition, the same code | symbol is attached | subjected and demonstrated to the same part as FIG. 4, FIG.

This connection structure A is composed of two unit structure bodies 1A and 1B each having a hollow pillar standing at least at four corners in a state of being adjacent to each other in the lateral direction, the outer surface of one unit structure pillar, The outer surface of the column of the unit structure is positioned using the connector 15, and the opening 15 is provided on each of the opposing outer surfaces of the columns of each unit structure. And a connecting member 17 projecting from both surfaces of the substrate at the same position. The connecting members 17 are fitted in the openings formed in the unit structures. The unit structure is characterized by being clamped between the outer surfaces of the columns.
That is, the opening 10 is formed in the opposing surface of two adjacent pillars 2A and 2B, and the connecting member 15 is inserted between the pillars with the connecting member 17 fitted in each opening 10. By connecting, the connecting structure A between the two unit structures 1A and 1B is constructed.
According to this connection structure A, the lateral positioning between adjacent unit structures can be performed without using a joint member or temporary fixing with a bolt.

Thus, the connection structure A of the present invention can be used for connection between unit structures stacked in the vertical direction and unit structures adjacently arranged in the horizontal direction.
That is, the unit structure connection structure A according to each of the embodiments described above is a state in which two unit structures provided with hollow columns standing at least at four corners are arranged adjacently in the vertical or horizontal direction. The appropriate position of the outer surface of each column of the unit structure and the appropriate position of the outer surface of each column of the other unit structure are positioned using the connector 15, and one unit structure and the other The unit structures are each provided with openings 10 and 11, and the connector 15 includes a substrate 18 and connecting members 17 projecting from both surfaces of the substrate. Furthermore, the substrate 18 is clamped between the unit structures in a state where the connecting members 17 are fitted in the openings formed in the unit structures.

FIG. 7B is a perspective view showing a state after connecting the columns of the unit structures on the upper and lower floors. It is possible to position the columns 2 and 52 in the horizontal direction by inserting the joining shear pipes (connectors) 31 into the openings 2a and 52a at the upper and lower ends of the hollow square columns 2 and 52, respectively. it can. After the assembled state shown in FIG. 7B, the bolts 33 and nuts are screwed using the respective screw holes provided on the side surfaces of the pillars 2 and 52 and the joint sheath tube 31 to fix them. To do.
The joining sheath pipe (connecting tool) 31 is equivalent to the connecting tool of the above embodiment in that the connecting member 31b protrudes from the upper and lower surfaces of the substrate 31a. Each connecting member 31b is fitted into each opening 2a, 52a to perform positioning. In this example, the planar shape of the connecting member 31b and the openings 2a and 52a is a square, but other shapes such as a polygon, a circle, an ellipse, an oval, etc. other than a rectangle may be used.

FIG. 7C is a perspective view showing a state in which two columns of two unit structures are connected to each other, and a view showing a joining sheath pipe 35 (substrate 35a, connecting member 35b) used for the connection. The connecting sheath pipe 35 has two connecting members 35b projecting from one side of the large-area substrate 35a through a predetermined gap, and other surfaces so as to face the connecting members on the other surface of the substrate. Two connecting members 35b are projected. The side plates constituting each pillar enter into the gap.

It is the figure which looked at the positional relationship of the opening part and connection member 45 of each connection base part from the plane direction.
The description will be made with reference to FIG. 1, FIG. 2, FIG.

  In the connection structure A according to the present embodiment, the pillars 2 and 52 of the unit structures 1 and 50 include connection base portions 55 and 56 having openings 55a and 56a, respectively, and the connection tool 41 includes connection members. 45, each connecting member has a small-diameter barrel portion 47 having one end fixed to the substrate surface, a larger diameter than the trunk portion, and A large-diameter locking portion 49 that is coaxially integrated with the other end of the body portion. Each trunk portion 47 has an axial length that is equal to or greater than the thickness of the coupling base portions 55 and 56, and has a radius that is the shortest distance from the center (opening center) 60 of the openings 55a and 56a to the inner periphery of the opening. The engaging portion 49 has a shape that fits inside the first circle 61 that is r1, and the inside of the second circle 63 that has the radius r2 as the longest distance from the opening center 60 to the inner periphery of the opening. It has a shape that fits in. In addition, the shape and dimension are set so that the trunk | drum 47 can rotate when it is located in an opening part. The locking portion 49 can move forward and backward in the axial direction in the opening by using the inner peripheral edge that is the longest distance from the center of the opening.

Hereinafter, the connecting structure of the unit structures according to this embodiment will be described in more detail.
The connection tool 41 includes a substrate 43 and a connection member 45 having the same shape formed so as to protrude symmetrically from the upper and lower surfaces of the substrate 43. The connecting member 45 includes a small-diameter barrel portion 47 having one end fixed to both surfaces of the substrate 43, a large-diameter locking portion 49 that is coaxially stacked and integrated with the other end portion of each barrel portion 47, and have. Each of the openings 55a and 56a and the connecting member 45 (the trunk portion 47 and the locking portion 49) has a rotationally symmetric shape when viewed from the axial direction.
The body 47 may have any shape as long as it can be rotated in the opening when fitted into the openings 55a and 56a. Further, the axial length of the trunk portion 47 is set to be longer than the thickness of the connection base portions 55 and 56 provided with the openings.
The locking portion 49 can be inserted into the opening when the rotation direction angle with respect to the opening is in a constant state (the state shown in FIG. 10A). The state shown in FIG. 10B) The inner edge of the opening is crossed to the outside and cannot be inserted into the opening. That is, when the locking portion 49 is moved in the axial direction and inserted into the opening with the axial center of the locking portion 49 and the center of the openings 55a and 56a aligned, the maximum diameter of the locking portion If the directional long portion is inserted so as to coincide with the maximum radial direction long portion (diagonal direction) of the opening, the locking portion can be inserted into the opening, but cannot be inserted when it deviates from the angle.

Next, the procedure for assembling the connecting member 45 with respect to the connecting base portion 55 of the column 2 on the lower floor will be described with reference to the plan view, but the same applies to the connecting base portion 56 of the column 52 on the upper floor. is there.
The connection base portions 55 and 56 are provided with openings 55 a and 56 a having a quadrangular (polygonal) shape as viewed from one axial end side (plan view direction) of the column 2 or the column 52. The openings 55a and 56a have the same planar shape (opening shape) and are oriented in the same angle direction, and when the upper floor unit structure is seated with good consistency on the upper surface of the lower floor unit structure. The sides and the corners of the corners coincide with each other and are in a positional relationship in which they are aligned and communicated.
Prior to assembling the upper-floor unit structure 50 on the lower-floor unit structure 1, the connection tool 41 is connected to the upper end of the pillar 2 of the lower-floor unit structure, that is, the opening 55 a of the connection base 55. The operation of inserting one (downward) of the member 45 is performed. The bottom of the unit structure 50 on the upper floor suspended by heavy equipment such as a crane is inserted into the lower floor while the connecting member 45 of the connector is inserted into all the openings 55a to maintain the angle (rotational direction angle) at the time of insertion. The unit structure 1 is lowered and seated while aligning the positional relationship with the upper surface of the unit structure 1. At this time, by vertically lowering the unit structure 50 on the upper floor, it becomes possible to smoothly insert the connecting member 45 on the upper side of the connector into the opening 56a on the bottom surface of each column 52. Thus, after inserting each connection member of a connection tool in both opening parts 55a and 56a, the board | substrate of a connection tool is rotated a predetermined angle (45 degree | times) with a tool, and the upper and lower connection base parts 55 and 56 are used. You can lock between.

Hereinafter, the fixing procedure using the coupler will be described in detail.
First, the connecting member 45 below the connector 41 is inserted into the lower opening 55a. In the present embodiment, the opening 55a is a quadrangle, but the contour (cross shape) of the projection shape of the locking portion 49 of the connecting member 45 seen from the plane direction is within the inner periphery of the opening 55a. The engaging portion 49 of the connecting member 45 can be inserted into the opening 55 a of the connecting base portion 55.
The planar shape of the locking portion 49 according to this example is a cross shape, and the distance L between the ends of the two protruding pieces 49a and 49b facing each other is less than the diagonal length of the opening 55a (56a). For this reason, the latching | locking part 49 can be smoothly inserted in an opening part by inserting the coupling tool 41 in an opening part from a plane direction so that each protrusion 49a, 49b may follow the diagonal of an opening part. Since the trunk portion 47 is significantly smaller in diameter than the opening portion and has an axial length that exceeds the thickness of the plate material that constitutes the opening portion, the connector 41 is in a state in which the trunk portion 47 enters the opening portion. Can be rotated with respect to the opening.

Next, the relationship between the locking portion 49 and the opening 55a (56a) will be described with reference to FIG.
The center of the opening 55a having a square planar shape formed on the upper end surface of the pillar 2 is defined as an opening center 60, and a first circle having a radius r1 as the shortest distance from the opening center 60 to the inner periphery of the opening is defined as 61. On the other hand, a second circle having a radius r <b> 2 as the distance from the opening center 60 to the inner peripheral edge of the opening farthest in the planar contour of the locking portion 49 is defined as 63.
Further, a circle having a radius r3 as a distance between the central portion (axial center) C of the connecting member 45 and the distal end portions of the projecting pieces 49a and 94b constituting the central portion C and the locking portion 49 is third. The circle 64.
The relationship between the diameter r1 of the first circle 61, the diameter r2 of the second circle 63, and the diameter r3 of the third circle 64 is r1 <r2, r3.
The tip of each projecting piece 49a, 94b is sized and shaped so as to be located between the first circle 61 and the second circle 63, and each projecting piece is the longest position from the opening center 60. It is comprised so that the inside of an opening part can be advanced / retracted when it faces to the inner peripheral part (4 corners) in a.
When the connecting member 45 is inserted into the opening, the center 60 of the opening having a rotationally symmetric shape and the axis C of the connecting member having the same rotationally symmetric shape can be substantially matched. Accordingly, when the body 47 is positioned in the opening and the connector 41 is rotated in the opening, the connecting member 45 can rotate about the opening center 60. The rotation center of the connecting member 45 and the center of the opening are not necessarily rotated unless they coincide with each other.

  In the connector 41 according to the present embodiment, the locking portion 49 is inserted into the opening 55a attached to one end of the pillar 2 in the posture shown in FIG. 10, and the substrate 43 is rotated clockwise or counterclockwise after the insertion. Since it is necessary to rotate 45 degrees in either of the clockwise directions, the contour of the projected shape seen from the plane direction of the body 47 must be located inside the first circle 61 having a small diameter. Further, after the substrate 43 is rotated 45 degrees, a part of the locking portion 49 (projections 49a and 49b) protrudes from the connection base portion 55 (periphery of the opening 55a) in the outer diameter direction. It is necessary to play a role of restricting the movement of the connector 41 in the vertical direction (thickness direction of the connection base portion) (dropping from the opening). For this reason, the radius r2 of the second circle 63 that passes through the inner peripheral edge of the opening farthest from the opening center 60 and is a locus of a circle centering on the opening center 60 is larger than the radius r1 of the first circle 61. The protrusions 49a and 49b are locked onto the connection base portion 55 as shown in FIG. As a result, the protruding pieces 49a and 49b of the locking portion 49 protrude and are locked on the outer diameter side beyond the inner peripheral edge of the opening 55a.

After the lower locking portions 49 of the respective connecting tools are locked in the openings 55a of all the pillars 2, the upper unit structure 50 is moved to the lower unit structure without rotating the connecting tools. Lower on the body 1. At this time, the openings 56a at the four corners of the bottom surface of the upper unit structure 50 are connected to the upper connecting members 45 of the respective connecting tools 41 set in the openings 55a at the four upper corners of the lower unit structure 1. Therefore, both unit structures are laminated with the substrate 43 of the connector sandwiched therebetween.
By satisfying the structural requirements as described above, each locking portion 49 can be inserted into each opening, and the protruding piece of the locking portion 49 can be rotated by rotating the connector 41 within the opening after insertion. 49a, 49b protrudes in the outer diameter direction beyond the periphery of the opening, and does not fall off in the axial direction from the opening.
By using this coupling tool, it is possible to prevent not only the horizontal displacement of each unit structure but also the vertical displacement.

11A to 11C are a perspective view and a plan view showing another embodiment of the connector according to the present invention.
The connection tool 41 has two connection members 45 that protrude in symmetrical positions on both surfaces of the substrate 43. The connecting member 45 includes a small-diameter barrel portion 47 and a large-diameter locking portion 49 integrated on the trunk portion 47 in the same axial center as the trunk portion.
The connection tool 41 is different from the connection tool 41 shown in FIG. 8 in that the outer surface of the projecting pieces 49a and 49b constituting the locking portion 49 is inclined inwardly toward the tip (in a tapered shape). ) In other words, the connector 41 of the present embodiment is configured such that the cross-sectional area in the direction orthogonal to the axial direction of the locking portion 49 gradually decreases as the tip end portion of the locking portion 49 approaches. The method of using the connector 41 is the same as that of the connector 41 according to the embodiment. That is, in order to make it easy to insert the locking portion 49 into the opening 55 a of the connection base portion 55, the cross-sectional area of the end portion of the locking portion 49 is formed small. Also in the connecting device having such a configuration, the locking portion 49 is inserted into the opening 55a of the connecting base portion 55, and when the body portion 47 reaches the opening, the substrate 43 is moved in either the clockwise direction or the counterclockwise direction. By rotating 45 degrees to 45 degrees, the lower end on the body 47 side, which is a part of the connecting member 45, comes into contact with one end of the connecting base part 55, and the vertical movement of the pillar 2 or the pillar 52 can be restricted.

Next, FIG. 12 (a) thru | or (c) are figures which show other embodiment of the coupling tool 41 based on this invention.
The connection tool 41 has two connection members 45 that protrude in symmetrical positions on both surfaces of the substrate 43. The connecting member 45 includes a small-diameter barrel portion 47 and a large-diameter locking portion 49 integrated on the trunk portion 47 in the same axial center as the trunk portion.
The connector 41 includes three projecting pieces 49c in which locking portions 49 constituting the connecting member 45 are projected at intervals of 120 degrees. In other words, the projection shape (planar shape) when the locking portion 49 is viewed from the axial direction projects the projecting piece 49c in three directions from the center of the shaft, and the outline thereof is a substantially star shape. Further, the planar shapes of the openings 55a and 56a provided at the upper end of the column 2 and the lower end of the column 52 are equilateral triangles so that the locking portion 49 can be inserted. It is the same as that of the said embodiment by the point which locks the latching | locking part to the periphery of each opening by rotating after inserting the latching | locking part 49 in an opening.
Similarly to the embodiment of FIG. 11, the outer surface of each protruding piece 49 c may have a tapered shape that is inclined inward toward the distal end.

In the present embodiment, the locking portion 49 has a distance r3 from the center C to the tip of the protruding piece 49c, and the radius r2 is the distance between the inner peripheral portion farthest from the opening center 60 and the opening center 60. It is configured to be inside the second circle 63 and to be positioned on the outer diameter side of the first circle 61 that is a concentric circle. For this reason, when the locking portion 49 is inserted into the opening so that each protrusion 49c faces the top of the triangular opening, the opening can be moved back and forth in the axial direction.
Further, the contour of the projection shape (planar shape) viewed from the axial direction of the column of the body portion 47 is from the opening center 60 which is the center of the opening 55a on the plane orthogonal to the axial direction of the column to the inside of the opening 55a. The shortest distance to the periphery is configured to be inside the first circle 61 having a radius r1. Thereby, after inserting the locking portion 49 into the opening portion 55a of the connection base portion 55, the substrate 43 can be rotated in either the clockwise direction or the counterclockwise direction.
When the locking part 49 is inserted into the opening and the body part 47 reaches the opening, when the coupling tool is rotated in one direction by 60 degrees, the projecting piece 49c comes into contact with the peripheral surface of the opening 55a. The movement in the axial direction of the connector 41 with respect to 2 can be restricted.
In the actual assembling work, one locking portion 49 is inserted into the opening 55 a of the pillar 2, and then the opening 56 a of the upper unit structure 50 is fitted into the upper locking portion 49 in that state. Combine. In this state, the substrate 43 is sandwiched between the two unit structures. In this state, by rotating the connector 41 by 60 degrees, each projecting piece 49c is placed on the peripheral surface of both the openings 55a and 56a. It will be in the locked state.

Next, FIGS. 13A and 13B are diagrams showing another embodiment of the connection base portion 55 according to the present invention. The connection base portion 55 has a connection member 45 inserted into the opening 55a. A restricting projection (rotation restricting portion) 65 for restricting the movement (rotation) of the locking portion 49 in the circumferential direction is provided. By providing the restricting projection 65 for controlling the movement of the locking portion 49 in this way, after the locking portion 49 is inserted into the opening 55a of the connection base portion 55, the substrate 43 is viewed only in the clockwise direction when viewed from the axial direction. It can be rotated, and after rotating 45 degrees, it can be controlled not to rotate any more. Therefore, it is possible to prevent the contact function between the lower end on the body 47 side and one end of the connection base portion 55 from being reduced due to excessive rotation, and the connection function of the connection member 45 from being impaired.
In addition, also in the triangular opening 55a according to the embodiment shown in FIG. 12, a restricting projection 65 for restricting the movement of the engaging portion 49 is provided at the peripheral portion so as to restrict the engaging portion 49 from rotating more than necessary. It may be configured.

  In addition, the rotation direction of the coupler 41 regulated by the regulation projection (rotation regulating portion) 65 is not the same for all the openings, but is opposite for two openings that are opposed along, for example, diagonal lines. That is one way. For example, for one opening 55a, a restricting projection 65 is provided so as to restrict the clockwise rotation as shown in FIG. 13, while the other opening 55a at a position diagonal to this opening is provided. By providing a restricting protrusion so as to restrict the counterclockwise rotation, the unit structures are rotated about the respective connecting devices 41 after the unit structures are connected adjacently in the vertical or horizontal direction. It is possible to prevent displacement in the direction.

Next, FIG. 14 is a plan view showing a modification of the shape of the opening.
The openings 55a and 56a include a first circle 61 having a radius r1 connecting the opening center 60 and a point having the closest distance from the opening center 60 among the inner peripheral edges of the opening, and the opening center 60. And a second circle 63 having a radius r2 connecting a point farthest from the opening center 60 in the inner peripheral edge of the opening.
For this reason, the latching | locking part 49 of the connector 41 in each said embodiment can be inserted in an opening part through the recessed part 55b which protruded in the outer-diameter direction provided in the inner peripheral edge of an opening part. Moreover, since the trunk | drum 47 is settled in the 1st circle | round | yen 61, it can rotate within an opening part.
For this reason, after inserting the locking part 49 into the opening part via the recess 55b, the trunk part 47 is moved into the opening part and rotated, so that the locking part is moved to the inner peripheral edge of the opening part other than the recess 55b. Can be locked.
In each of the embodiments after FIG. 8, an example in which the opening shape of the opening and the end surface shape of the connecting member are rotationally symmetric has been shown. However, after the locking portion is inserted into the opening, the body portion is centered. As long as the protrusion can be locked to the periphery of the opening by being rotated as shown in FIG.

  FIGS. 15A to 15C are diagrams for explaining a connection state when the vertical pillars 2 and 52 of the unit structure on the upper and lower floors are connected using the connector 41 shown in FIG. is there. First, as shown in FIG. 15A, the lower locking portion 49 of the connector 41 is inserted into the opening 55 a at the upper end of the column 2. Subsequently, as shown in (b), the unit structure 50 is overlaid so that the upper locking portion 49 fits into the opening 56a of the upper-level unit structure 50. In this state, the substrate 43 of the connector 41 is in a state of projecting sideways from the joint surfaces of the columns 2 and 52. Subsequently, as shown in (c), the base plate 43 is rotated around the body portion 47 until each side of the base plate 43 coincides with each side of the upper and lower ends of the pillar, whereby the projecting pieces 49a of the locking portion 49, 49b becomes the state which protruded in the outer-diameter direction from the peripheral edge of each opening part 55a, 56a, and can control the motion of the pillars 2 and 52 in the axial direction. That is, in FIG. 15B, the corners of the substrate protruding from the edge of the upper and lower unit structures are pushed between the unit structures, whereby the locking between the openings by the locking portions 49 is completed. In addition, the code | symbol 81 is a spacer which has the same thickness as the thickness of the board | substrate 43 of the connector 41, and is used as needed.

Reference numeral 85 denotes a lifting hole formed in the upper part of the pillar of each unit structure, and is used when the unit structure is lifted by inserting hooks such as cranes individually.
In this way, the unit structures constituting the upper and lower floors are stacked to perform horizontal positioning, and at the same time, the vertical movement of the pillars of the unit structure is restricted, and then the bolts for fixing the upper and lower floor unit structures, etc. By fixing with, it becomes possible to firmly fix the unit structures on the upper and lower floors.
Note that the connection structure A according to each of the embodiments from FIG. 8 onward can also be applied to the case where the unit structures are connected in the horizontal direction as shown in FIG.
As described above, according to the present invention, when positioning the end of each pillar of the upper and lower floor unit structures in order to construct a building in which the unit structures are stacked, the bolts penetrating the upper and lower floor unit structures. The centering of the holes is not required, and the units on the upper and lower floors can be easily positioned in the horizontal direction.
Moreover, when connecting a unit structure with a connection tool in the state which adjoined to the horizontal direction, the position shift to an up-down direction and a horizontal direction can be prevented.
