  However, in the unit building disclosed in Patent Document 1, the horizontal rigidity of the unit building is ensured by arranging the passing beams in the gaps between the building units without any gaps. There is a possibility that the material cost for arranging the material increases.

  In addition, in the unit building disclosed in Patent Document 2, since structural instability becomes unstable when only the columns are connected by the connecting members, the structural plane is stretched over the entire length between the beam members. Ensures rigidity.

  In this way, if the rigidity between the beams is increased too much over the entire length in the longitudinal direction by using a crossing beam, the beam materials are difficult to bend, and the original characteristics of the frame structure that absorb energy by deformation can be fully exhibited. There is a risk of disappearing.

  On the other hand, when connecting members are arranged in the form of dots between the beam members of adjacent building units, stress is concentrated on the connecting members.

  Therefore, an object of the present invention is to provide a unit building connection structure capable of ensuring the required strength while maintaining the original characteristics of the frame structure, and a unit building including the unit building connection structure.

  In order to achieve the above object, the unit building connection structure according to the present invention includes at least a pair of side-by-side arrangements in a unit building formed by adjoining a plurality of building units, each of which has a framework formed of beams and pillars. A connecting structure of unit buildings in which a connecting member is arranged in a clearance for floor plan adjustment formed between the building units, wherein the connecting member is arranged at a position where the beam material between the building units is in the longitudinal direction and Beams facing each other in the gap so that deformation in the width direction of the gap is constrained and deformation in the longitudinal direction of the beam material and in the width direction of the gap is allowed between the connecting members in the longitudinal direction of the beam material. The members are connected by the connecting member at both ends in the vicinity of the joint with the column member, and the connecting member extends along each of the beam members facing each other in the gap. A side wall portion, a pair of width-direction side wall portions that connect the beam-side side wall portions, and a face material portion that closes the inside of the outline formed by the beam-side side wall portion and the width-direction side wall portion. It is characterized by being.

  Here, the beam side wall portion may be fixed to the beam material by a plurality of bolts arranged at intervals in the longitudinal direction of the beam material. In addition, the width side wall portion and the face material portion are integrally formed of a grooved steel material, and the beam side wall portion is formed of an end plate that closes a side surface of the grooved steel material. be able to.

  Furthermore, the said face material part can be set as the structure which forms the lower surface of the said connection member. Further, a spacer may be interposed between the beam side wall portion and the beam material. Further, the column member and the beam member are joined via a joining frame member having a contact surface that abuts on each side surface, and the connecting member is joined to the beam member via the joining frame member. It may be a fixed configuration.

  Moreover, it can be set as the structure by which the hole for position adjustment is provided in the said beam side wall part and the said beam material which fixes it.

  In the unit building according to the present invention, the gap is 20-30 cm wide, and a floor panel is installed above the gap between the beam members to be the floor beams of the building unit. Features.

  The connecting structure of the unit buildings of the present invention configured as described above is such that the beam members facing each other in the gap for adjusting the layout between the building units are connected by connecting members at both ends in the longitudinal direction, and the arrangement of these connecting members is arranged. The deformation in the longitudinal direction of the beam material and the width direction of the gap between the building units is constrained at the location. On the other hand, deformation in the longitudinal direction of the beam material and the width direction of the gap is allowed between the connecting members.

  In this way, at both ends in the longitudinal direction between the beam members, if the deformation in the longitudinal direction of the beam member between the building units and the width direction of the gap is constrained, it is necessary to arrange the structural member in the other part. And a simple configuration. In addition, the beam material can be deflected at locations other than where the connecting members are arranged, so that when a large earthquake occurs, the frame structure can be deformed to absorb the earthquake energy and prevent the unit building from collapsing. Can do.

  And since the connecting member that connects the building units is configured to block the inside of the outline formed by the beam side wall portion and the width direction side wall portion with the face material portion, the length of the beam material between the building units is It is possible to strongly resist the force in the direction and the width direction of the gap. Further, if the rigidity is high with respect to the force in two directions as described above, it is possible to resist the force that causes torsion.

  Furthermore, if it is the structure which fixes a beam side side wall part to a beam material with a volt | bolt, a connection member can be easily attached to the clearance gap between building units. Moreover, if a connection member is comprised with a channel steel material and an end plate, it can manufacture easily and cheaply.

  Furthermore, if a face material part is the structure which forms the lower surface of a connection member, after installing a building unit, a connection member can be attached by the operation | work from the top. In addition, if the spacer is interposed between the beam side wall portion and the beam material, even if there is a gap wider than the width of the connecting member between the building units, the connecting member should be closely attached and fixed. Can do.

  In addition, if the joint member is reinforced by joining the column member and the beam member through the joint frame member, and the connection member is fixed through the joint frame member, a stronger connection structure and can do.

  In addition, if holes are provided in the beam side wall and the beam material that fixes it, the position of the building unit and the connecting member can be adjusted by inserting and operating a bar-shaped tool such as a hole in the holes. Can be done. As a result, it is possible to adjust the position between the building units facing each other with a gap therebetween.

  Furthermore, if the gap is 20-30 cm wide, the floor panel can be installed across the floor beams without reinforcing the floor panel and increasing the rigidity. Since the size of the unit building can be adjusted by the gap, the shape and floor plan of the unit building can be freely designed without the restriction of multiple building units.

  Next, the construction method of the unit building connection structure of the present embodiment will be described. First, as shown in FIGS. 8 and 9, the building units 1A and 1B conveyed from the factory are hung down at predetermined positions on the site where the unit building 10A is constructed.

  At this time, if the building units 1A and 1B can be installed at the correct positions from the beginning, it is not necessary to make the following adjustments. If not, in order to attach the connecting member 2 manufactured to the specified dimensions. Then, fine adjustment of the position using the surface adjustment jigs 4A and 4B is performed.

  The surface adjustment jigs 4A and 4B are jigs used for changing the relative distance between the two building units 1A and 1B. Here, since the surface adjustment jig 4A and the surface adjustment jig 4B differ only in length, the configuration will be described using the surface adjustment jig 4A as an example.

  The surface adjustment jig 4A includes a pair of insertion portions 41 and 42 attached to the building unit 1A and the building unit 1B, and a connecting rod 430 that connects the distances between the insertion portions 41 and 42 in a changeable manner. It is mainly composed of

  The connecting rod 430 includes a screw rod 43 engraved with a right screw inserted into the insertion portion 41, a reverse screw rod 44 engraved with a left screw inserted into the insertion portion 42, and a screw rod 43. And a joint 45 that connects the reverse screw rod 44 to each other.

  Further, the insertion portions 41 and 42 are provided with columnar leg portions 41 a and 42 a, respectively, and these leg portions 41 a and 42 a are inserted into the suspension holes 11 a and 11 a provided at the upper end of the column 11. Thus, it is prevented from moving in the horizontal direction with respect to the building units 1A and 1B to which the insertion portions 41 and 42 are attached.

  A screw groove (not shown) is formed on the inner periphery of the insertion portion 41, and the screw rod 43 portion of the connecting rod 430 is screwed into the screw groove. The position of the insertion portion 41 with respect to the screw rod 43 is changed by rotating the insertion portion 41 around the screw rod 43 before the leg portion 41a of the insertion portion 41 is inserted into the suspension hole 11a. be able to. Further, the end of the screw rod 43 protruding from the insertion portion 41 is formed into a hexagonal columnar hexagonal portion 43 a that matches the hole shape of the wrench 46.

  On the other hand, a reverse screw groove (not shown) is also formed on the inner periphery of the insertion portion 42, and the reverse screw rod 44 portion of the connecting rod 430 is screwed into the reverse screw groove. That is, when the connecting rod 430 is rotated, the distance between the insertion portions 41 and 42 is reduced or separated depending on the rotation direction.

  And when the space | interval of the width direction of the clearance gap 101 of building units 1A and 1B differs from the length of the connection member 2, the surface adjustment jig | tool 4A is attached as shown in FIG. adjust.

  In this fine adjustment, first, the leg portion 41a of the insertion portion 41 of the surface adjustment jig 4A is inserted into the suspension hole 11a of the column 11 of the building unit 1A, and the leg portion 42a of the insertion portion 42 is inserted into the building unit 1B. It inserts in the suspension hole 11a of the pillar 11 of this.

  Subsequently, the wrench 46 is fitted to the hexagonal portion 43a protruding outward from the insertion portion 41, and the connecting rod 430 is rotated. Then, although it changes with rotation directions, while the insertion part 41 moves relatively to either direction of an axial direction with respect to the screw rod 43, the insertion part 42 is the insertion part 41 with respect to the reverse screw rod 44. It moves relatively in the direction opposite to the moving direction. Accordingly, the building unit 1A and the building unit 1B move. Thus, by using the surface adjustment jig 4A, the interval in the width direction of the gap 101 can be adjusted to the interval between the insertion portions 41 and 42.

  On the other hand, when there is a shift in the longitudinal direction of the ceiling beams 13, 13 between the building units 1A, 1B, fine adjustment is performed using the surface adjusting jig 4B as shown in FIG. The leg portions 41a and 42a of the surface adjusting jig 4B are inserted into holes 132 and 132 provided in the upper flanges of the ceiling beams 13 and 13, respectively.

  Then, in the gap 101 adjusted to match the size of the connecting member 2 in this way, the connecting member 2 oriented so that the face material portion 222 becomes the lower surface as shown in FIG. Fit from above 1B. At this time, if there is a separation of 1 mm or more between the joining frame member 14 and the end plate 21 of the connecting member 2, the spacer 24 is interposed.

  Subsequently, the bolt 23 fitted with the joint washer 232 is inserted into the hole 21a of the end plate 21 from the inside of the building units 1A and 1B. Further, a flat washer 234, a spring washer 233, and a nut 231 are mounted on the shaft of the bolt 23 protruding above the face member 222 from above the building units 1A and 1B, and the bolt 23 is mounted until the spring washer 233 becomes flat. tighten.

  Next, the effect | action of the connection structure of the unit building of this Embodiment is demonstrated.

  In the connecting structure of the unit building 10A of the present invention thus configured, the ceiling beams 13 and 13 facing each other in the gap 101 between the building units 1 and 1 are connected by connecting members 2 and 2 at both ends in the longitudinal direction. The deformation in the longitudinal direction of the beam material between the building units 1 and 1 and the width direction of the gap 101 is restrained. Here, the longitudinal deformation of the beam material between the building units 1 and 1 means that the longitudinal displacement of the ceiling beam 13 is relatively generated between the building units 1 and 1. Moreover, the deformation | transformation of the width direction of the clearance gap 101 means that the displacement of the direction where the distance between the building units 1 and 1 approaches or leaves | separates arises.

  On the other hand, between the connecting members 2, 2, a highly rigid structural member such as the connecting member 2 is not disposed along the longitudinal direction of the ceiling beam 13, so that the longitudinal direction and the vertical direction of the ceiling beam 13 and the gap 101 are arranged. Deformation in the width direction is allowed.

  As long as the deformation in the longitudinal direction of the ceiling beam 13 between the building units 1 and 1 and the width direction of the gap 101 are constrained at both ends in the longitudinal direction between the ceiling beams 13 and 13, the other portions It is not necessary to dispose a structural member in the case, and a simple configuration with reduced material costs can be achieved.

  Moreover, since the ceiling beams 13 and 13 can be bent at places other than the place where the connecting members 2 and 2 are arranged, the ceiling beam 13 constituting the frame structure (frame structure) is connected to the connecting members 2 and 2 when a large earthquake occurs. It is possible to prevent damage such as the unit building 10A collapsing due to absorption of the earthquake energy due to the deformation at the non-rigid portion therebetween.

  The connecting member 2 that connects the building units 1 and 1 has a face member 222 on the inner side of a rectangular outline in plan view formed by the pair of end plates 21 and 21 and the pair of width side walls 221 and 221. It is configured to close with.

  If the rigidity is high with respect to the force in two directions as described above, the force in the longitudinal direction of the ceiling beam 13 between the building units 1 and 1, the force in the width direction of the gap 101, and the force that causes twisting. It can be made to resist strongly.

  And by providing the connection member 2 in the vicinity of the joint portion between the column 11 having a high strength and the ceiling beam 13 in this way, the ceiling beam 13 is prevented from being deformed by a horizontal force transmitted through the connection member 2. Can do.

  Furthermore, if it is the structure which fixes the end plate 21 to the ceiling beam 13 with the volt | bolt 23, the connection member 2 can be easily attached to the clearance gap 101 between the building units 1 and 1. FIG.

  Further, by joining the column 11 and the ceiling beam 13 via the joint frame member 14, the joint part is reinforced, and by fixing the connecting member 2 via the joint frame member 14, A stronger connection structure can be obtained. In particular, if the end plate 21 is brought into close contact with the joining frame member 14 by tightening the bolt 23 and the nut 231 with a high force for the high-strength bolt, the joint strength can be further increased by friction joining.

  Further, if the connecting member 2 is constituted by the channel steel material 22 and the end plates 21 and 21, it can be manufactured easily and inexpensively. Furthermore, by adjusting the thickness of the end plate 21 and the thickness of the joint washer 232, the strength of the connecting member 2 on the ceiling beam 13 side can be adjusted. For this reason, the fatal deformation | transformation of the building unit 1 can be prevented by selecting the end plate 21 and the joint washer 232 of the thickness which does not concentrate stress on the joining frame material 14.

  Moreover, if the face material part 222 is the structure which forms the lower surface of the connection member 2, after installing the building unit 1, the connection member 2 can be attached by the operation | work from the top. Further, if the spacer 24 is interposed between the end plate 21 and the joining frame member 14, even if the gap 101 wider than the width of the connecting member 2 is opened between the building units 1, 1, the connecting member 2 can be fixed in close contact with the joining frame member 14.

  Further, if the gap 101 is 20-30 cm wide, even if the cross joist 321 of the floor panel 32 is wood having a thickness of about 15-21 mm and a cross-section of about 30-50 mm in width, it is between the floor beams 12, 12. The floor panel 32 can be installed across.

  Furthermore, since the size of the unit building 10A (10B) can be adjusted by the gap 101 (102), the shape and floor plan of the unit building 10A (10B) can be freely designed, leaving the size limit of multiples of the building unit 1. can do.

  Hereinafter, an example of a mode different from the above-described embodiment will be described with reference to FIGS. The description of the same or equivalent parts as the contents described in the above embodiment will be described with the same terms or the same reference numerals.

  As shown in FIG. 10, the connecting member 2A described in this embodiment is provided with an adjustment hole 5 as a position adjusting hole in an end plate 21A as a beam side wall portion.

  The adjustment hole 5 is drilled between the holes 21a and 21a into which the bolts 23 of the end plate 21A are inserted. Moreover, the adjustment holes 5 and 5 are provided in each of a pair of opposing end plates 21A and 21A.

  On the other hand, as shown in FIG. 11, an adjustment hole 134 as a position adjustment hole is provided in the ceiling beam 13 and the joint frame member 14 at a position where the connecting member 2 </ b> A is attached, in accordance with a position facing the adjustment hole 5. . The adjustment holes 134 and 134 are also provided in the facing ceiling beams 13 and 13 and the joint frame members 14 and 14 on both sides of the gap 101, respectively.

  Next, the construction method of the united building connection structure of the embodiment will be described. First, the building units 1A and 1B conveyed from the factory are suspended at a predetermined position on the site where the unit building 10A is constructed as shown in FIG.

  Then, the connecting member 2A is fitted from above into the gap 101 between the building units 1A and 1B, and the tips of 51 and 51 are inserted into the adjustment holes 134 and 134 from the inside of the building units 1A and 1B, respectively. Direct toward 21A adjustment holes 5 and 5.

  At this time, if the building units 1A and 1B can be installed at the correct positions from the beginning, both the ridges 51 and 51 are inserted straight into the respective adjustment holes 5 and 5, and are connected by the ridges 51 and 51. The member 2A can be temporarily supported.

  On the other hand, when there is a shift in the longitudinal direction of the ceiling beams 13 between the building units 1A and 1B, the shin 51 is operated to make a fine adjustment.
