Description

  The present invention relates to a connecting member that connects building units, and a unit building that includes the connecting member.

Conventionally, a unit type building composed of a plurality of building units is known. In such a unit type building, as shown in Patent Document 1, for example, a configuration is adopted in which adjacent building units are connected by a shear plate to improve the rigidity of the unit type building.
By the way, in recent years, a unit type building having a structure in which the height of the building unit is different (for example, see Patent Document 2) and a structure having a mezzanine floor or a skip floor portion (for example, see Patent Document 3) is widely used. Has been.

The unit type building described in Patent Document 2 employs a configuration in which building units having different heights are connected to each other by using a joining plate in which steps having different heights are formed in steps. It has been.

And a nut 86B to be stopped.
And the orthogonal building unit 20A, 20B from which the height from a ground level differs and the building unit 10A are connected because the clamping board part 81 is attached and fixed to the attaching part 85 by the connection part 86. FIG.

The connecting member 9 is formed in a substantially rectangular plane so that it can be attached over a region including the joints 14 and 24.
Specifically, the connecting member 9 includes a sandwiching plate portion 91 formed in a substantially rectangular plane, and an attachment portion 85 and a connecting portion 86 of the connecting member 8.
The sandwiching plate portion 91 is configured so that the pair of sandwiching plate portions 81 have the support wall portions 81B and 81C so that the support wall portion 81C of the other sandwiching plate portion 81 is positioned inside the support wall portion 81B of the one sandwiching plate portion 81. It is configured to overlap each other in the bending direction.
In addition, the thickness dimension of a pair of clamping board part 81 is formed so that it may become the same dimension as the distance of orthogonal building unit 20A, 20B and building unit 10B. Specifically, the total dimension of the height dimension of the support wall part 81B of the sandwiching plate part 81 and the thickness dimension of the flat plate part 81A is the distance between the orthogonal building units 20A, 20B and the building unit 10B.

Function as. For this reason, even if the nut 86B of the connecting portion 86 is tightened, the support wall portions 81B and 81C prevent the pair of sandwiching plate portions 81 from being bent close to each other, and the sandwiching plate portion 91 is securely attached. Fixed.

[Effects of Embodiment]
According to the above embodiment, the following effects can be obtained.
(1) Along the plane X including the mouths 14 of the building units 10 adjacent in the vertical direction and the mouths 24 of the orthogonal building units 20 having different heights adjacent in the horizontal direction of these building units 10. Rectangular sandwiching plate portions 81 and 91 including the openings 14 and 24 are arranged. Attachment portions 85 are respectively attached to the columns 11 and 21 that are respectively continuous with the joint 14 of each building unit 10 and the joint 24 of the orthogonal building unit 20. By attaching the sandwiching plate portions 81 and 91 to the attachment portion 85 by the connecting portion 86, the sandwiching plate portions 81 and 91 straddle the joint 14 of each building unit 10 and the joint 24 of the orthogonal building unit 20 having different heights. It is attached.
As a result, the connected state of the adjacent building unit 10 and the orthogonal building unit 20 having different heights can be obtained using the sandwiching plate portions 81 and 91 having a simple planar rectangular shape, and the building unit 10 and the orthogonal building unit 20 are obtained. Even if a stress is applied in the horizontal direction, which is an adjacent direction, the clamping plate portions 81 and 91 are in a state of resisting the stress. That is, transmission of horizontal force between the building unit 10 and the orthogonal building unit 20 can be ensured. For this reason, even when the structure in which the separation part 6 is provided or the separation interval is widened, torsion and the like can be suppressed, and the rigidity of the entire unit type building 1 can be secured. Furthermore, the rectangular clamping plate portions 81 and 91 in the regions including the joints 14 and 24 of the building units 10 and the orthogonal building units 20 having different heights are connected to the attachment portions 85 attached to the columns 11 and 21 to the connecting portions 86. The building unit 10 and the orthogonal building unit 20 having different heights can be connected with a simple configuration to be attached, and the workability can be improved.

(2) The supporting wall portions 81B and 81C functioning as spacers in contact with each other in the vicinity of the position where the connecting portion 86 in the holding plate portion 91 penetrates, that is, in the opposing holding plate portion 81 are bent.
For this reason, even if a gap is generated between the adjacent building unit 10 and the orthogonal building unit 20 due to the structure of the unit type building 1 and design reasons, the support wall portions 81B and 81C absorb the gap and the building unit 10 And the orthogonal building unit 20 can be connected without rattling, and the rigidity of the entire unit type building 1 can be secured.
In addition, the support wall portions 81B and 81C can increase the strength of the sandwich plate portion 81 and can be formed thinly, and it is not necessary to use a separate spacer, and the cost of the unit building 1 can be reduced. .

(3) By providing the connecting portion 86 with a bolt 86A that passes through the sandwiching plate portions 81 and 91 and is attached to the mounting portion 85, for example, the sandwiching plate portions 81 and 91 are orthogonal to the adjacent building unit 10 using a nut 86B. It can be firmly attached to the building unit 20.
For this reason, the rigidity of the entire unit type building 1 can be secured with a simple structure using the bolt 86A.

(4) As the attachment portion 85, the attachment plate portion 85B to which the sandwiching plate portions 81 and 91 are attached is bent at one edge of the fixing portion 85A attached to the pillars 11 and 21 of the building unit 10 and the orthogonal building unit 20. Is configured.
For this reason, the sandwiching plate portions 81 and 91 can be easily attached to the plane X including the joints 14 and 24 of the adjacent building unit 10 and the orthogonal building unit 20 with a simple structure having an L-shaped cross section.

(5) As the connecting members 8 and 9 for connecting the building unit 10 and the orthogonal building unit 20 having different heights, the sandwiching plate portion constituting the sandwiching plate portion 81 of the connecting member 8 and the sandwiching plate portion 91 of the connecting member 9 81 and the same shape.
That is, the sandwiching plate portion 81 includes a flat plate portion 81A and support wall portions 81B and 81C bent in the same direction on both sides in the longitudinal direction of the flat plate portion 81A, and is formed in a C-shaped cross section. The height of the support wall 81B is the same as the sum of the height of the other support wall 81C and the thickness of the flat plate 81A. 91 can be configured.
Thus, when the building unit 10 and the orthogonal building unit 20 are connected on the one plane X side, only one connecting member 8 is used, and the building unit 10 and the orthogonal building unit 20 are located between the building unit 10 and the orthogonal building unit 20. In the case of connection, the pair of clamping plate portions 81 may be used as the connection member 9 that is used in a face-to-face relationship, and the cost of connecting the building unit 10 and the orthogonal building unit 20 can be reduced by sharing the material.

(6) When the building unit 10 and the orthogonal building unit 20 are connected, the plate members 7 and 72 are connected at the same height, and the connecting members 8 and 9 are connected at different heights. Use.
For this reason, construction of the unit type building 1 is easy, and each building unit 10 and the orthogonal building unit 20 can be reliably and firmly connected.

[Modification of Embodiment]
It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements and the like within a scope that can achieve the object of the present invention are included in the present invention.
For example, although the unit type building 1 which uses the building unit 10 and the orthogonal building unit 20 in combination is illustrated, the building unit 10 is configured by appropriately combining building units having different height dimensions and can not be connected by the shear plates 71 and 72. It can also be applied to the unit type building 1. For example, in the said embodiment, although it was set as the structure which provided the orthogonal building unit 20 for 1 row, it is good also as a structure which provided the multiple rows, and also the structure where the building unit 10 and the orthogonal building unit 20 adjoin in the perpendicular direction. Furthermore, as the unit type building 1, the structure which does not use the separation part 6 can also be made into object.

And although the structure which uses the shear plates 71 and 72 was illustrated in the location where the height dimension becomes the same, you may connect using the connection members 8 and 9 without using these.
Further, although the connecting member 8 has been described using the place where the plane X is desired on the outer surface, the connecting member 9 may be used instead of the connecting member 8. That is, for example, as shown in FIG. 10, a pair of clamping plate portions 81 may be opposed to each other and connected.
With this configuration, by using the pair of sandwiching plate portions 81, the strength of the sandwiching plate portion 91 can be improved without providing a dedicated member, and the rigidity of the entire unit type building 1 can be further improved.

Furthermore, in the said embodiment, although the structure which connects the building unit 10 and the orthogonal building unit 20 of the positional relationship which the joints 14 and 24 from which height differs in the connection member 9 was illustrated, as shown, for example in FIG. It can also be used in locations where four building units 10 and orthogonal building units 20 are connected or three are connected. For convenience of explanation, FIG. 11 shows a stepped cross section at the position of the attachment portion 85.
As shown in FIG. 11, the building units 10 adjacent to each other in the horizontal direction or the building unit 10 and the orthogonal building unit 20 are connected to each other via a plane X including the openings 14 and 24 of the building unit 10 and the orthogonal building unit 20. A sandwiching plate portion 91 is disposed between the building unit 10 and the orthogonal building unit 20 that are adjacent in the horizontal direction. Attaching portions 85 are attached in pairs to the opposing positions of the opposing pillars 11 and 21 of the adjacent building units 10 and 20 via the sandwiching plate portion 91. The connecting portion 86 penetrating the sandwiching plate portion 91 is attached to the attaching portion 85 that forms a pair. The sandwiching plate portion 91 is attached to each building unit 10 and the orthogonal building unit 20 in a state of being sandwiched between the building units 10 and the orthogonal building units 20 that are adjacent to each other in the horizontal direction via the plane X.
For this reason, in the configuration shown in FIG. 11, the building units 10 and 20 that are adjacent in the horizontal direction via the plane X are also connected by one clamping plate portion 91, and there is no need to attach the clamping plate portion 91 to the plane X, Connection work can be reduced.

And although the same clamping board part 81 was comprised facing as the connection member 9, it is not this limitation.
For example, as shown in FIG. 12, for example, one sandwiching plate portion 81 is provided with a pair of support wall portions 81B, and the other sandwiching plate portion 81 is provided with a pair of support wall portions 81C, and one sandwiching plate portion 81 is provided. The other sandwiching plate portion 81 may be positioned inside.

Further, as the opposing arrangement of the pair of sandwiching plate portions 81, the supporting wall portion 81C is arranged so as to overlap the inside of the supporting wall portion 81B. However, for example, as shown in FIG. .
In other words, the support wall portions 81B and 81C may be arranged to face each other on both sides of the position where the connecting portion 86 penetrates. In this configuration, the through hole 81D may not be provided at a position close to the support wall portion 81C.
As shown in FIG. 13, since the support wall portions 81 </ b> B and 81 </ b> C are located on both sides of the connecting portion 86, the deformation of the flat plate portion 81 </ b> A due to the attachment of the connecting portion 86 can be prevented. Moreover, even if the gaps between the adjacent building units 20 and the orthogonal building units 20 are different by shifting the opposing sandwiching plate portions 81 in the width direction, versatility can be further improved.

Further, as the connecting member 9, the support wall portions 81 </ b> B and 81 </ b> C of the pair of opposing sandwiching plate portions 91 function as spacers, but a separate spacer 93 may be used as shown in FIG. 14, for example. The spacer 93 has an insertion hole (not shown) through which, for example, steel materials 93A having a C-shaped cross section are arranged to face each other and the connecting portion 86 is inserted.
By using the separate spacer 93 shown in FIG. 14, even when the gap between the building unit 10 and the orthogonal building unit 20 facing each other through the plane X is different, the spacer 93 having a different height is appropriately changed and used. It is sufficient to improve versatility.
The spacer 93 is not limited to the hollow structure in which the steel members 93A having a C-shaped cross section are arranged to face each other, and for example, the solid portion or the cylindrical shape is attached and fixed without rattling. It can have any possible shape. Also, the material is not limited to metal, such as ceramics or wood, and any material that can be mounted and fixed without rattling can be applied.

Furthermore, as the connecting members 8 and 9, the configuration using the sandwiching plate portion 81 having a rectangular shape and a C-shaped cross section bent on both sides in the longitudinal direction is illustrated, but not limited to this shape, various shapes of a rectangular shape are used. Things are available.
For example, the connecting member 95 shown in FIG. 15 is provided with a spacer 93 at a location where the connecting portion 86 penetrates in the rectangular flat plate-shaped holding plate portion 95A. These spacers 93 may be either integrated or separated from the clamping plate portion 95A. Alternatively, the spacer 93 may be provided only on one side of the holding plate portion 95 </ b> A corresponding to the connecting member 8.
With the configuration as shown in FIG. 15, the sandwiching plate portion 95 </ b> A has a simple plate-like structure, and the cost can be reduced as compared with the connecting members 8 and 9. In particular, when the gap between adjacent building units 10 and orthogonal building units 20 to be connected is narrow, the holding plate portion 95A may be directly attached without using the spacer 93 only on one side or at all, and the gap is narrow. It is especially effective in cases.
Note that, as the sandwiching plate portion 95A, for example, a sandwiching plate portion 91 in which a pair of sandwiching plate portions 81 are disposed to face each other as in the connecting member 9 may be used.

Further, for example, a connecting member 96 shown in FIG. 16 or a connecting member 97 shown in FIG. 17 may be used.
That is, the connecting member 96 shown in FIG. 16 is a member in which a spacer 93 is provided on a sandwiching plate portion 96A formed by bending a rectangular steel plate into a S-shaped cross section in the middle in the width direction. In addition, the connecting member 97 shown in FIG. 17 is formed by bending a rectangular steel plate into an S-shaped cross section in the middle of the width direction, and bending both sides in the longitudinal direction in the opposite direction to form an S-shaped cross section. A spacer 93 is provided on the holding plate portion 97A.
16 and the connecting member 97 shown in FIG. 17, for example, can firmly connect the building unit 10 and the orthogonal building unit 20 having different heights. In these embodiments, since the sandwiching plate portions 96A and 97A are bent with a thickness dimension of the spacer 93, the gap between the building unit 10 and the orthogonal building unit 20 needs to be wide and the spacer 93 needs to be used. Even in this case, it is difficult for twist to occur with respect to the stress applied in the horizontal direction, and the rigidity of the entire unit building 1 can be improved.

Moreover, although the clamping plate part 81 and the attachment part 85 were demonstrated as a separate body, it is good also as an integral structure, for example. In such a configuration, for example, in a configuration in which the parts are integrally connected by welding, the welded portion functions as the connecting portion 86. In such a configuration in which the attachment portion 85 is integrally attached, the attachment portion 85 may be placed in contact with the pillars 11 and 21 while being positioned at a position where the sandwiching plate portion 81 is connected.
On the contrary, the pillars 11 and 21 and the attachment part 85 are integrally attached in advance to form the building unit 10 or the orthogonal building unit 20, and the sandwiching plate parts 81 and 91 are attached at the connection part 86 at the site construction. Also good.
Further, in each of the above embodiments, the spacer 93 may not be provided.

And the building unit 10, the orthogonal building unit 20, and the connection beam 30 may be connected by combined use of the shear plates 71 and 72 and the bolt joint. When used in combination, they can be connected to each other more firmly, and the structure of the entire building can be further improved.
In addition, even if the joint 14 of the building unit 10B and the joint 24 of the orthogonal building unit 20 are not arranged in a lame manner but are arranged at opposing positions, the joint 14, the joint 24, and the connecting beam 30 The end portion 31 may be connected by a substantially flat L-shaped shear plate 71, or may be connected by a substantially rectangular planar shear plate 72. Therefore, even if it is a case where it does not become lame arrangement, the orthogonal building unit 20 and the building unit 10B can be connected more firmly.
In addition, the specific structure and procedure for carrying out the present invention may be changed to other configurations as long as the object of the present invention can be achieved.

  The present invention can be used for a unit type building to which building units having different height dimensions are connected.
