  However, no unit building has been disclosed which can cope with the limit on the north side slope line and can expand the building area beyond the limit of multiples of the building unit.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a unit building that can cope with restrictions on the north-side inclined line and various external appearances and can expand the building area beyond the restriction of multiples of building units.

  In order to achieve the above object, the unit building of the present invention is a unit building configured by adjoining a plurality of building units each of which a framework is formed by a beam material and a column material, and includes a long column and a short column. A trapezoidal unit that is a building unit in which trapezoidal both side surfaces are formed by oblique beams and beam members that connect between the upper end portions thereof and a beam member that connects between the lower end portions, and a rear surface that is the long column side of the trapezoidal unit. A box-shaped unit that is a rectangular parallelepiped building unit arranged with a gap, and a beam member on the back side of the trapezoidal unit and a beam member of the box-shaped unit facing each other at substantially the same height across the gap. A connecting member that connects, and the connecting member is formed by a pair of end plates that extend along each of the facing beam members of the gap, and a channel steel material that connects the end plates. Ruko The features.

  Here, at least a part of the lower end surface or the upper end surface of the end plate is in contact with the inner surface of the web of the channel steel, and the side end surfaces on both sides of the end plate are in contact with the inner surface of the flange of the channel steel, It is preferable that welding joining is performed at the place where

  Moreover, it can be set as the structure by which the hole for position adjustment is provided in the said end plate and the said beam material which fixes it. Furthermore, a spacer can be interposed between the end plate and the beam member.

  And a clearance gap can be used as a clearance gap for floor plan adjustment. The gap can be set to a width of 20-30 cm.

  In the unit building of the present invention configured as described above, the trapezoidal unit and the box-shaped unit are arranged with a gap therebetween, and the beam members are connected by a connecting member. The connecting member is formed by a pair of end plates and a channel steel material that connects the end plates.

  By arranging the trapezoidal unit with the inclined surface as the upper surface in this way, it is possible to cope with the restriction on the north-side inclined line and to change the appearance of the building. Further, since the size of the unit building can be adjusted by the gap, the shape of the unit building, the floor plan, etc. can be freely designed without the restriction of multiple building units.

  Further, since the connecting member is composed of the channel steel material and the end plate, it can be manufactured easily and inexpensively. Furthermore, since it is formed in a box shape by the end plate and the channel steel, it is possible to strongly resist the longitudinal force of the beam material between the building units and the force in the width direction of the gap.

  For example, the beam members facing each other in the gap between the building units are connected by connecting members at both ends in the longitudinal direction, and the deformation of the beam material in the longitudinal direction and the width direction of the gap between the building units is performed at the place where the connecting members are arranged. Restrain. On the other hand, the connecting members are allowed to be deformed in the longitudinal direction of the beam material and in the width direction of the gap.

  In this way, at both ends in the longitudinal direction between the beam members, if the structure is such that the deformation in the longitudinal direction of the beam members between the building units and the width direction of the gap is restrained by a highly rigid connecting member, the structural member in the other part Therefore, a simple configuration can be obtained. 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.

  In addition, by making the end surface of the end plate in contact with the inner surface of the channel steel material and performing welding joint at the contact location, it is possible to make a structure that is highly rigid against force in multiple directions and strong against torsion. .

  Furthermore, if the end plate and the beam material for fixing the end plate are provided with holes, the position of the building unit and the connecting member is adjusted by inserting and operating a bar-shaped tool such as a hole in the hole. be able to. As a result, it is possible to adjust the position between the building units facing each other with a gap therebetween.

  Furthermore, if it is the structure which interposes a spacer between an end plate and a beam material, even if the clearance gap wider than the width | variety of a connection member is opened between building units, a connection member can be stuck and fixed. .

  Further, if the gap is a clearance for adjusting the floor plan, the degree of freedom in designing the floor plan can be increased. 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.

  Then, as shown in FIG. 10, the connecting member 3 is fitted into the gap 101 between the trapezoidal unit 2 and the box-shaped unit 12 from above, and the adjustment holes 275 and 153 are inserted into the adjustment holes 275 and 153 from the inside of the trapezoidal unit 2 and the box-shaped unit 12 respectively. The tips of the inserted rod-shaped tools (not shown) are directed toward the adjustment holes 31b and 31b of the end plates 31 and 31, respectively.

  At this time, if the trapezoidal unit 2 and the box-shaped unit 12 can be installed at the correct positions from the beginning, both shins are inserted straight into the respective adjustment holes 31b and 31b, and the connecting member 3 is moved by the shin. Temporary support is possible.

  On the other hand, when there is a deviation in the longitudinal direction of the beam material between the trapezoidal unit 2 and the box-shaped unit 12, the shingle is inserted and operated for fine adjustment (position adjustment). That is, the relative alignment between the trapezoidal unit 2 and the box-shaped unit 12 is performed, and the entrance / exit of the surfaces of the long column 22 and the column 13 with the gap 101 interposed therebetween is eliminated.

  When making fine adjustments using the Shino, first, the bolt 33 with the joint washer 332 is inserted from the inside of the trapezoidal unit 2 (or the box-shaped unit 12) toward the beam-side bolt hole 274 (152).

Further, a flat washer 334, a spring washer 333 and a nut 331 are attached to the shaft of the bolt 33 protruding from the hole 31 a of the end plate 31 from above the gap 101, and the bolt 33 is tightened. The temporary fixing with the bolt 33 is performed in the holes 31a and 31a on both sides of the adjustment hole 31b.

  Then, fine adjustment is performed by operating the inserts inserted into the end plate 31 on the side not temporarily fixed by the bolts 33 and 33 and the adjustment hole 153 (275) on the beam side.

  Thus, after adjusting the trapezoidal unit 2 and the box-shaped unit 12 and the connecting member 3 facing each other with the gap 101 interposed therebetween, the bolts 33 and the like are installed in all the holes 31a,. Wear. When the width of the connecting member 3 does not match the width of the gap 101 and there is a separation between the end plate 31 and the side surface 276 of the waterside beam 27, as shown in FIG. Insert the number of spacers 34 that can be inserted by hand without using a screw etc., and tighten all the bolts 33,... Until the spring washers 333,.

Thus, relative alignment between the building units can be performed using a bar-shaped tool such as a sword to eliminate the entry / exit of the column side face with the gap 101 interposed therebetween.

  In addition, since the connecting member 3 can be temporarily supported by inserting a tool such as the adjustment holes 31b, 153, and 275, the bolts 33, the nuts 331, and the like can be quickly mounted and tightened. Will be able to.

  In addition, as shown in FIG. 5, the connection by the connection member 3 is similarly performed between the ceiling beams 15 and 15 of the box-shaped units 11 and 11 on the first floor.

  Next, the operation of the unit building of the present embodiment will be described.

  In the unit building 1 of the present invention configured as described above, the trapezoidal unit 2 and the box-shaped unit 12 are arranged with a clearance 101 for arrangement adjustment, and the beam members are connected by the connecting member 3. The connecting member 3 is formed by a pair of end plates 31, 31 and a channel steel material 32 that connects the end plates.

  By arranging the trapezoidal unit 2 having the inclined surface as the upper surface in this way, it is possible to cope with the limitation on the north side inclined line. Further, by installing the trapezoidal unit 2 at the uppermost part of the unit building 1, the appearance of the building can be changed, and the heavy unit building 1 with unevenness can be obtained. Furthermore, if the trapezoidal unit 2 is installed adjacent to the box unit 12 on the second floor, it can be used for a solarium or an attic.

  Furthermore, since the size of the unit building 1 can be adjusted by the gap 101, the shape and floor plan of the unit building 1 can be freely designed without the limitation of the size of multiples of the box-shaped units 11, 12, etc.

  Further, if the connecting member 3 is constituted by the channel steel 32 and the end plates 31, 31, the connecting member 3 can be manufactured easily and inexpensively. Further, by adjusting the thickness of the end plate 31 and the thickness of the joint washer 332, the strength of the connecting member 3 toward the beam member can be adjusted. For this reason, fatal deformation of the trapezoidal unit 2 and the box-shaped units 11 and 12 can be prevented by selecting the end plate 31 and the joint washer 332 having such a thickness that the stress is not concentrated on the beam material.

  The connecting member 3 has a configuration in which a web 322 covers an inner side of a quadrilateral outline formed by the pair of end plates 31 and 31 and the pair of flanges 321 and 321. More specifically, the end surface of the end plate 31 is fitted so as to be in close contact with the inner surface of the channel steel 32, and a welded joint (welded portion 35) is applied to the contact portion.

  By using the connecting member 3 in this configuration, a structure having high rigidity with respect to forces in a plurality of directions is obtained, and the longitudinal force of the ceiling beam 15 between the trapezoidal unit 2 and the box-shaped unit 12, the gap 101 It is possible to firmly resist the force in the width direction and the force that causes torsion.

  Then, the water beam 27 and the ceiling beam 15 facing each other with the gap 101 interposed therebetween are connected by connecting members 3 and 3 at both ends in the longitudinal direction, and the beam material between the trapezoidal unit 2 and the box unit 12. The deformation in the longitudinal direction and the width direction of the gap 101 is restrained. Here, the longitudinal deformation of the beam material means that a displacement of the beam material in the longitudinal direction is relatively generated between the building units. The deformation in the width direction of the gap 101 means that a displacement in a direction in which the distance between the building units sandwiching the gap 101 approaches or leaves is generated.

  On the other hand, since no rigid structural member such as the connecting member 3 is disposed between the connecting members 3 and 3 along the longitudinal direction of the beam material, the longitudinal and vertical directions of the beam material and the width of the gap 101 Directional deformation is allowed.

  In this way, at both ends in the longitudinal direction of the beam material between the building units, if the configuration is such that deformation in the longitudinal direction of the beam material between the building units and the width direction of the gap 101 is constrained, the structural member is provided in the other portions. Therefore, a simple configuration with reduced material costs can be achieved.

  Further, since the ceiling beam 15 can be bent at places other than the place where the connecting members 3 and 3 are arranged, the ceiling beam 15 constituting the frame structure (frame structure) is connected between the connecting members 3 and 3 when a large earthquake occurs. It can be bent at the non-rigid portion, the earthquake energy is absorbed by the deformation, and the unit building 1 can be prevented from being damaged.

  In addition, by providing the connecting member 3 in the vicinity of the joint between the column 13 and the ceiling beam 15 having high strength in this way, the ceiling beam 15 is prevented from being deformed by a horizontal force transmitted through the connecting member 3. Can do.

  Furthermore, if it is the structure which fixes the end plate 31 to the ceiling beam 15 or the waterside beam 27 with the volt | bolt 33, the connection member 3 can be easily attached to the clearance gap 101 between the trapezoidal unit 2 and the box-shaped unit 12. FIG. .

  Further, by joining the column 13 and the ceiling beam 15 via the joining frame member 16, the joining portion is reinforced, and by fixing the connecting member 3 via the joining frame member 16, A stronger connection structure can be obtained. In particular, if the end plate 31 is brought into close contact with the joining frame member 16 by tightening the bolt 33 and the nut 331 for a high-strength bolt and tightening with a strong force, the joining strength can be further increased by the friction joining.

  Further, if the adjustment holes 31b, 275, and 153 are provided in the end plate 31 and the beam material that fixes the end plate 31, respectively, by inserting and operating a bar-shaped tool such as a hole in these holes, Position adjustment with the connection member 3 can be performed. As a result, the position adjustment between the building units facing each other across the gap 101 can be performed simultaneously.

  Further, if the web 322 forms the lower surface of the connecting member 3, after the trapezoidal unit 2 and the box-shaped unit 12 are installed, the connecting member 3 can be attached by work from above. Further, if the spacer 34 is interposed between the end plate 31 serving as the beam side wall portion and the beam member, the gap 101 wider than the width of the connecting member 3 between the trapezoidal unit 2 and the box unit 12. Even if is open, the connecting member 3 can be fixed in close contact with the beam member side.

  Further, if the gap 101 has a width of 20-30 cm, the floor panel (not shown) for closing the gap 101 may not be reinforced to increase the rigidity. For example, even if the floor joist is a floor panel having a thickness of about 15-21 mm and a width of about 30-50 mm and a particle board having a thickness of about 15-20 mm, the under beam 23 and the floor beam 14 It can be installed across.
