[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a connector for connecting building units having rectangular parallelepiped frames in which upper and lower ends of pillars at four corners are connected by beams in a horizontal direction.
[0002]
[Background]
2. Description of the Related Art Conventionally, a unit type building that is manufactured by manufacturing a box-shaped building unit at a factory and combining a plurality of building units at a construction site has been used.
According to the unit type building, interior materials, exterior materials, and equipment members are attached to the building unit in advance at the factory, so the work at the construction site can be greatly reduced, and the building can be constructed in a short period of time. it can.
The building unit has a substantially rectangular parallelepiped frame in which upper and lower ends of pillars standing at four corners are connected by beams.
On the upper surface of the frame, braces are bridged on a diagonal line for reinforcement, and the brace prevents deformation of the planar shape of the frame and ensures the rigidity of the building unit.
[0003]
Building units adjacent to each other are connected by a flat connector. An example is shown in FIG.
The building units 10 adjacent to each other are arranged with a gap D as shown in FIG. 5, and the stigmas 11A are connected to each other by a building unit connector 110 as a standard connector. In addition, in order to determine the relative position of the building unit 10, two large and small positioning pins 11B and 11C protrude from each capital 11A.
This building unit connector 110 is a substantially square iron plate disposed across the dense portions of the pillars 11 and includes a plate portion 111 disposed on each pillar head 11A.
The plate portion 111 includes holes 112 and 113 for inserting the positioning pins 11B and 11C, and bolts and nuts for fixing the building unit connector 110 to the building unit 10 and connecting the upper and lower building units 10 to each other. A hole 114 for inserting the fastener 120 is formed.
And the joint strength of adjacent building units 10 is securable by connecting and fixing each stigma 11A of the building unit 10 with such a connecting tool 110 for building units.
[0004]
By the way, in order to form the stepped portion on the outer wall surface of the unit-type building in a plan view, it can be dealt with by arranging a small building unit 91 having a small short side dimension adjacent to the building unit 41 as shown in FIG.
However, when the small building unit 91 is employed, the number of building units increases, and therefore, work on the construction site increases.
Then, as FIG. 7 shows, it is possible to join the two building units 41 and 42 by making the side surfaces from which a horizontal length dimension differs adjoin.
In such a case, in order to transmit the horizontal force F smoothly, two sets of braces 421 and 422 are erected on the building unit 41 having a longer side to be joined, and the horizontal plane of the building unit 41 is constructed. Need to be reinforced.
[0005]
[Problems to be solved by the invention]
However, when the braces 421 and 422 are arranged side by side along the short side, the angle between the pair of braces 422 installed on the projecting portion becomes an acute angle, and sufficient rigidity cannot be ensured. The building units with different horizontal length dimensions of the side surfaces to be abutted were not adjacent to each other.
For this reason, even if the horizontal length dimensions of the abutted side surfaces are different, a connector that does not impair the rigidity of the horizontal connecting portion of the building unit is desired.
The applicant of the present application has proposed a structure in which a building unit is reinforced using plywood instead of braces (see Japanese Patent Laid-Open No. 10-266353). However, if it does in this way, the man-hour will increase in manufacturing a building unit.
[0006]
An object of the present invention is to provide a connector that ensures the rigidity of a connecting portion between building units having different horizontal length dimensions of side surfaces to be faced.
[0007]
[Means for Solving the Problems]
The connector of the present invention will be described with reference to the drawings. The building units 41A and 43 having a rectangular parallelepiped frame in which the upper and lower ends of the four corner columns 411 and 431 are connected by beams 412 and 432 are adjacent to each other in the horizontal direction. And the building units 41A and 43 have different horizontal length dimensions on the side surfaces facing each other, and according to the horizontal length dimension of the side surface on which one building unit 41A is abutted. The first connection portion 61 and the second connection portion 62 corresponding to the horizontal length dimension of the abutted side surface of the other building unit 43 are integrated.
In the present invention as described above, the connecting tool 60 in which the first connecting portion 61 and the second connecting portion 62 are integrated is easily manufactured by cutting out the corners of a rectangular metal plate (for example, an iron plate) into a square shape. Will come to be. And the rigidity of a horizontal direction is improved by attachment of the flat connector 60, and if the four pillars 411 and 431 of the side surface where the building units 41A and 43 face each other are integrated with this connector 60, Even if the horizontal length dimensions of the abutted side surfaces are different, the horizontal external force F is smoothly transmitted from the other building unit 43 to the one building unit 41A, and the horizontal length of the abutted side surfaces The rigidity of the connecting portion between the building units 41A and 43 having different dimensions is ensured.
[0008]
In the above, in the building units 41A and 43, the other side surfaces intersecting the abutted side surfaces form the same surface, and two other building units 41B are arranged along these side surfaces, It is desirable that the one connection portion 61 and the second connection portion 62 extend to the top of the pillar 411 of the other two building units 41B and connect the building units 41B to each other.
Here, in connecting the building units 41A and 43 having different horizontal lengths of the side surfaces to be abutted with another building unit 41B along the building units 41A and 43, the first connecting portion 61 and the second connecting portion 41 and the second connecting unit 41B are connected. When trying to connect the four building units 41A, 41B, 43 with a connector other than the connection having the connection portion 62, the two connectors are overlapped, and the height level is different from other horizontal connectors.
Then, if it carries out as mentioned above, since building unit 41A, 41B, 43 can be connected by one connector 60, the height level of the horizontal connection part of building unit 41A, 41B, 43 may differ. There is no problem in placing the upper floor building unit.
[0009]
The building units 41A and 43 preferably have long sides and short sides having different lengths in plan view, and the abutted side surface is preferably a short side surface.
In this way, if the side surfaces on the short side of the building units 41 </ b> A and 43 are abutted and connected, the first and second connection portions 61 and 62, the second connection portions 61 and 62, than the case where the side surfaces on the long side are abutted and connected. Since the lengths of the beams 412 and 432 connected by the first and second connection portions 61 and 62 are shortened, higher rigidity is secured, and it is easier to secure rigidity that can resist the horizontal external force F.
[0010]
Further, the building units 41 having the same horizontal length dimension on the opposite side surfaces are positioned so that the positioning pins 11A and 11B for positioning the upper floor building unit 41 placed on the building unit 41 are inserted. The first connecting portion is connected by a standard connector 110 having holes 112 and 113 and a bolt insertion hole 114 for inserting a bolt 120 for connecting a plurality of building units 41B arranged adjacent to each other in the horizontal direction. 61 and the second connecting part 62 are preferably provided with the same positioning holes 61A, 61B, 62A, 62B and bolt insertion holes 61C, 62C as the standard connector 110, respectively.
If it does in this way, it will become possible to perform the connection operation of the said building units 41, without changing the conventional connection structure of the building units 41 adjacent to the up-down direction, and the work efficiency in a construction site will not be impaired here. .
[0011]
In addition, the first connection portion 61 is longer than the second connection portion 62 and is an intermediate portion of the first connection portion 61 that is opposed to the end of the second connection portion 62 in a plan view. It is desirable that a bolt insertion hole 61D through which a bolt for joining to the beam 412 is inserted is formed.
In this way, the beam 412 of the building unit 41A on the first connection portion 61 side is joined to the coupling tool 60 at the intermediate portion, so that even if the coupling tool 60 has a planar shape having a stepped portion, The horizontal external force F is not concentrated on the stepped portion of the connector, but is transmitted to the entire connector 60, and the durability of the connector is ensured.
[0012]

As shown in FIG. 3, the building units 41 </ b> A, 41 </ b> B, and 43 are connected to each other by a flat plate-like connection tool 60 in which corners of a flat rectangular metal plate are cut out in a square shape.
[0015]
The connector 60 has a first connecting portion 61 corresponding to the horizontal length dimension of the side face on the short side where the building unit 41A is abutted and a horizontal length dimension of the side face on the short side where the building unit 43 is abutted. And a corresponding second connecting portion 62.
The first connecting portion 61 has a length dimension obtained by adding the horizontal length dimension of the side surface on the short side of the building unit 41A and the length dimension of one side of the column 411 of the building unit 41B. The length dimension of the first connection portion 61 is larger than that of the second connection portion 62. The end of the connector 60 on the building unit 41B side extends to the top of the column 411 of the building unit 41B.
The first connecting portion 61 has positioning holes 61A and 61B through which the positioning pins 11A and 11B are inserted, a bolt insertion hole 61C through which the fastener 120 made of the bolt and nut is inserted, and a beam of the lower building unit 41A.

And the rigidity of a horizontal direction is improved by attachment of the flat connection tool 60 which integrated the 1st connection part 61 and the 2nd connection part 62, and building unit 41A, 43 was faced | matched by this connection tool 60. Since the four columns 411 and 431 on the side surfaces are integrated, the horizontal external force F is smoothly transmitted from the building unit 43 to the building unit 41A even if the horizontal length dimensions of the abutted side surfaces are different. As a result, the rigidity of the connecting portion between the building units 41 </ b> A and 43 having different horizontal length dimensions of the side surfaces to be abutted can be ensured.
[0017]
Moreover, since the 1st connection part 61 and the 2nd connection part 62 are extended to the top part of the pillar 411 of the building unit 41B, and the building units 41A, 41B, and 43 are connected with one connecting tool 60, the building units 41A and 41B. , 43 does not have different height levels, and no problem arises in placing the upper floor building unit.
[0018]
Furthermore, since the side surface where building unit 41A, 43 is faced is made into the short side surface, and building unit 41A, 43 is connected, it is 1st rather than the case where the long side surface is faced and connected. And the lengths of the second connecting portions 61 and 62 and the beams 412 and 432 connected by the first and second connecting portions 61 and 62 are shortened, higher rigidity is ensured, and rigidity that can resist the horizontal external force F is achieved. Can be secured more easily.
[0019]
Moreover, since the same positioning hole 61A, 61B and bolt insertion hole 61C as the standard coupling tool 110 are provided in the 1st and 2nd connection parts 61 and 62, conventional building unit 41A, 43 adjacent connection in the up-down direction is connected. The building units 41A and 43 can be connected to each other without changing the structure, and the work efficiency at the construction site is not impaired.
[0020]
Furthermore, since the intermediate part of the beam 412 of the building unit 41A on the first connection part 61 side is joined by the connecting tool 60, the horizontal external force F is generated even if the connecting tool 60 has a planar shape having a stepped part. Instead of concentrating on the stepped portion of the connection tool 60, it is transmitted to the entire connection tool 60, and the durability of the connection tool 60 can be ensured.
[0021]

Moreover, according to the coupling tool of Claim 2, in connecting a building unit from which the horizontal length dimension of the side face | abutted | matched differs from another building unit along these building units, a 1st connection part And if it is going to connect four building units with a connection tool different from the connection which has the 2nd connection part, two connection tools will be piled up and other horizontal connection tools will differ in height level.
Therefore, as described above, the building units can be connected to each other with one connector, so that the height level of the horizontal connecting portion of the building unit does not differ, and there is no need to place the upper floor building unit. There is no problem.
[0024]
Furthermore, according to the connection tool of claim 3, if the side surfaces on the short side of the building units are abutted and connected, the first and second connections are made more than the case where the long side surfaces are abutted and connected. Since the length of the portion and the beam connected at the first and second connection portions are shortened, higher rigidity is ensured, and rigidity that can resist horizontal external force can be more easily ensured.
[0025]
Moreover, according to the connection tool of Claim 4, it becomes possible to perform the connection operation | work of the said building units, without changing the connection structure of the conventional building units adjacent to the up-down direction, and at the construction site here Work efficiency is not impaired.
[0026]
Furthermore, according to the connector according to claim 5, since the beam of the building unit on the first connection portion side has the intermediate portion joined to the connector, the connector has a planar shape having a step portion. However, the horizontal external force is not concentrated on the stepped portion of the connector, but is transmitted to the entire connector, thereby ensuring the durability of the connector.
