Description

  The present invention relates to a box-shaped unit that can form a unit house or the like by stacking and integrating a plurality, for example, and more specifically, a plurality of prismatic columnar column portions and a wall portion extending between adjacent column portions. The present invention relates to a box-shaped unit formed in a box shape.

Conventionally, as this type of box-shaped unit, as shown in FIG. 12, screw members for connection are provided at both upper and lower end portions of the column 20 at the four corners of the box-shaped unit U so that the vertically adjacent units can be connected and fixed. There was one provided with a connecting portion J using 12.
Specifically, end face plates 21 are respectively provided at the upper and lower end portions of the rectangular column 20 and the end face plate 21 is provided with a screw member insertion hole 21a through which the connecting screw member 12 can be inserted. In order to secure an operation space for the screw member 12, all of the two outer peripheral surfaces of the end portion of the column portion 20 were cut out (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 53-22509 (FIGS. 1 and 2)

According to the above-described conventional box-shaped unit, since all the two outer peripheral surfaces are notched at the end of the column portion, the remaining two surfaces can bear the axial force as the column portion. When the unit weight is large, the shaft strength is insufficient and there is a risk of buckling the end of the column.
Furthermore, regarding the end face plate, only two sides of the four sides of the rectangular shape are supported by the column portion, and the remaining two sides are in an unsupported state. When an external force in the column axis direction acts between both box-shaped units in a cantilever state, the end face plate itself is easily bent up and down, resulting in an unstable connection state and a difficulty in securing sufficient connection strength. .

  Accordingly, an object of the present invention is to provide a box-type unit that solves the above-described problems, improves the axial strength of the column portion, and easily improves the coupling force between the box-type units.

  A first characteristic configuration of the present invention is a box-shaped unit that is formed in a box shape by providing a plurality of prismatic columnar column parts and a wall part that extends over adjacent column parts. An end face plate is provided at one of the end portions, and a screw member insertion hole through which a connecting screw member with another unit adjacent to at least one of the upper and lower sides of the column portion can be inserted is provided on the end face plate. A window portion that can be used at the time of screwing operation of the screw member is provided on one surface of the peripheral surface exposed to the outside of the column portion unit, and shafts that receive the axial force of the column portion are provided on both sides of the window portion. There is a force load reinforcement part in each place.

According to the first characteristic configuration of the present invention, an end face plate is provided on at least one of the upper and lower ends of the pillar portion, and the end face plate is adjacent to at least one of the upper and lower sides of the pillar portion. A screw member insertion hole through which a screw member for connection with the unit can be inserted is provided, and a window portion that can be used at the time of screwing operation of the screw member is provided on one surface of the peripheral surface exposed to the outside of the column portion. Therefore, when connecting to another adjacent unit, the screw member can be screwed through the window in a state where the screw member for insertion is inserted into the screw member insertion hole. it can. Therefore, the screwing operation of the screw member through the window portion can be performed from a large space outside the unit, and the unit connecting operation can be performed efficiently.
And since the axial force burden reinforcement part which receives the axial force of the said pillar part is provided in the both sides of the said window part, respectively, even when a big axial force acts on a pillar part from upper direction, the said window part It is possible to compensate for the reduction in the column strength due to the cross-sectional defect due to the axial force load reinforcing portion, and it is possible to secure sufficient axial force in the column portion as a whole unit.
Furthermore, the support state of the end face plate is also backed up by the axial force load reinforcing portion, so that it can be made a stable support state compared to the conventional cantilever support state, and between the two box-type units. It is possible to suppress bending of the end face plate when an external force in the column axis direction is applied.
Therefore, it is possible to ensure sufficient connection strength between the units.
As a result, it is possible to ensure sufficient strength even when the box-shaped units are stacked in an up-and-down manner and connected together, for example, for use as a building.

  According to a second characteristic configuration of the present invention, the end face plate is provided with a positioning mechanism that guides the positions of the units to a predetermined connection position during the connection operation with the another unit.

  According to the second characteristic configuration of the present invention, in addition to achieving the above-described operation and effect of the first characteristic configuration of the present invention, the end face plate is mutually connected during the connecting operation with the another unit. Since a positioning mechanism that guides the positions of the units to a predetermined connection position is provided, the positioning mechanism makes it easier to align each other when connecting to another unit that is connected to the box unit. It is possible to improve the connection work efficiency.

  According to a third characteristic configuration of the present invention, the positioning mechanism is configured by a dowel hole into which a dowel member extending over both units to be connected can be fitted.

According to the third characteristic configuration of the present invention, in addition to being able to achieve the above-described operational effect according to the first or second characteristic configuration of the present invention, the positioning mechanism includes a dowel member extending over both units to be connected. Since it is configured with dowel holes that can be freely inserted, the structure as a positioning mechanism is extremely simple as long as dowel holes are formed, so there is no need for formation and costs can be reduced. It becomes.
Furthermore, since the dowel hole itself does not protrude from the surface of the end face plate in a state where the dowel member is not inserted, for example, when a positioning mechanism is not required (when another unit is not connected adjacently). In this case, the end plate can be kept flat. Therefore, other objects are not caught on the projecting portion and become an obstacle. And since the dowel hole itself can be easily closed, it is hard to stand out in appearance, and it is easy to ensure good design.

  According to a fourth characteristic configuration of the present invention, the column end portion provided with the window portion is formed of a separate member from the column main body, and the column end portion and the column main body are integrally connected to form the column portion. It is where it is configured.

  According to the 4th characteristic structure of this invention, in addition to being able to achieve the above-mentioned effect by any one of the 1st-3rd characteristic structure of this invention, intensity | strength is attached to a pillar main body and a pillar edge part. For example, it is easy to select a high-strength material from the column main body toward the column end to cover the decrease in the strength of the column end due to a cross-sectional defect in the window. It becomes possible to adopt. In addition, such an improvement in design flexibility can be reflected in the freedom of shape design, for example, by forming the column end portion with a larger diameter with respect to the column body, regardless of the material alone. it can. According to this example, in the operation of arranging another box unit adjacent to each other in the horizontal direction, the column end portion protrudes in the horizontal direction from the column main body, thereby serving as a spacer. It is easy to prevent the column main bodies from coming into contact with each other and deforming, and the work can be carried out speedily. That is, installation workability can be improved.

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the parts indicated by the same reference numerals as those in the conventional example indicate the same or corresponding parts.

  FIG. 1 shows a multipurpose unit (hereinafter simply referred to as a unit) U which is an embodiment of a box-shaped unit of the present invention. For example, the internal space is used for an office space, a store space, a warehouse space, or the like. By arranging the units U shown in the figure in the vertical and horizontal directions and connecting them together, a more expandable building can be configured.

The unit U will be described.
The unit U is formed in a substantially rectangular parallelepiped box shape, and pillars 1 made of metal rectangular tubes are erected at four corners in plan view, and correspond to each of the adjacent pillars 1. A beam portion 2 made of a metal square tube is provided between the end portions, and a metal plate wall portion 3 is provided in an area surrounded by the adjacent column portion 1 and the beam portion 2. A metal plate ceiling 4 is provided in a range surrounded by the four beams 2, and a metal floor 5 is provided in a range surrounded by the lower four beams 2. .
In addition, an entrance / exit and a window opening / closing door 3a are provided at appropriate portions of the wall 3.
The unit U is configured such that units arranged in parallel in the horizontal direction and units stacked in the vertical direction can be integrated by bolt connection.
The connecting portions J between the units U are respectively formed on the pillar portions 1.

As shown in FIG. 2, the column part 1 is mainly composed of a rectangular tube material, and a rectangular metal end face plate 6 substantially matching the outer shape of the column cross section is provided at both upper and lower end parts thereof. Is provided.
In this embodiment, the column portion 1 is configured by integrally providing a connecting block (corresponding to a column end portion) 1B provided with the end face plate 6 at both ends of a column main body 1A made of a rectangular tube material. The connecting portion J is constituted by the connecting block 1B.

  The connecting block 1B includes the end face plate 6, a second end face plate 7 disposed in parallel with the end face plate 6 at intervals, each side of the end face plate 6, and each of the second end face plates 7. The first to fourth peripheral plates 8, 9, 10, and 11 that connect the sides are integrally provided.

The first peripheral surface plate 8 and the second peripheral surface plate 9 are provided on the two peripheral surfaces on the inner side of the unit U in the four peripheral surfaces of the column part 1, and the end surface plate 6 and the second peripheral surface plate 9. The two end face plates 7 are provided over the entire length of the corresponding side. The first peripheral surface plate 8 and the second peripheral surface plate 9 are set to have thicknesses larger than the thickness of the rectangular tube material of the column main body 1A, and on the extended surface of the peripheral surface of the rectangular tube material. (See FIG. 4).
On the other hand, the 3rd peripheral surface board 10 and the 4th peripheral surface board 11 are provided in the state located in the remaining 2 peripheral surfaces among the 4 peripheral surfaces of the pillar part 1, The said end surface board 6 and a 2nd end surface board 7 is provided over a part of the corresponding side. Specifically, the third peripheral surface plate 10 and the fourth peripheral surface plate 11 are connected to each other at their side edges, and in the present embodiment, are integrally formed of angle steel. The third peripheral plate 10 and the fourth peripheral plate 11 are set to have a thickness dimension larger than the thickness of the rectangular tube material of the column main body 1A, and on the extended surface of the peripheral surface of the rectangular tube material. (See FIG. 4).
Therefore, between the first peripheral surface plate 8 and the fourth peripheral surface plate 11 and between the second peripheral surface plate 9 and the third peripheral surface plate 10 are discontinuous in the column peripheral surface direction. This is a window portion W that can be used in the connection operation described later (see FIG. 3). And the said 1st-4th surrounding surface board 8, 9, 10, 11 located in the both sides of the window part W is thickly formed from the pillar main body 1A, and is reinforced, and column effective cross-sectional area is obtained. It is possible to compensate for the loss by the window portion, and the connecting block 1B is prevented from becoming weaker than the column main body 1A due to the action of the axial force on the column portion 1. The first to fourth peripheral plates 8, 9, 10, and 11 are referred to as an axial force load reinforcing portion P.

The end face plate 6 is provided with a screw member insertion hole 6a through which a connection screw member 12 with another unit to be connected can be inserted, at a position close to the window portion W.
Further, the end face plate 6 has a rectangular shape in which a dowel member 13B extending between both units to be connected can be fitted as a positioning mechanism 13 that guides the positions of the units to each other during a connection operation with another unit. A dowel hole 13A having a shape is provided substantially at the center.
Incidentally, when explaining an example of the dowel member 13B, as shown in FIG. 4, an intervening plate portion 13Ba interposed in a state where the end face plates 6 of both units to be connected are in surface contact with each other at the upper and lower central portions of the dowel member 13B. The dowel portion 13Bb is provided in a protruding state on the upper and lower surfaces of the interposition plate portion 13Ba. The dowel portion 13Bb is formed so that the protruding tip side is tapered, and is fitted to the dowel hole 13A at the initial stage of fitting even if the axial positions of the dowel portions 13B are slightly shifted. ing. Further, the dowel portion 13Bb is formed by increasing the thickness of the outer peripheral surface formed from the distal end side to the proximal end side, and as the fitting with the dowel hole 13A becomes deeper, the guiding effect of the inclined surface is increased. Guided so that the axial center position matches.
Therefore, in the state where the dowel member 13B is fitted in the dowel hole 13A at the upper end of the unit U that has been previously installed, the other unit U to be connected is lowered from above and the dowel portion 13Bb protruding. Furthermore, by further lowering down while fitting the dowel hole 13A at the lower end of the other unit U, the induction effect as described above can be exhibited, and the unit U can be set in a state without lateral displacement. Then, by inserting and screwing the connecting screw members 12 such as bolts and nuts into the screw member insertion holes 6a of the opposite end face plates 6 of both units U, the two units U can be reliably connected and integrated. Can do.
Since the dowel member 13B is interposed between the units U in a fitted state, the dowel member 13B becomes a shear resistance in the lateral displacement direction of both units U, and together with the connecting screw member 12, It is possible to maintain a strong connection between both units.
As described above, the dowel hole 13A serves as a positioning mechanism 13 by fitting the dowel member 13B. For example, the dowel hole 13A can be engaged with a hanging bracket or a hanging hook member. It can be used when lifting the unit U, or can be used by locking and connecting a connecting bracket with another unit arranged adjacently on the side.

As shown in FIGS. 2 and 3, the third peripheral surface plate 10 and the fourth peripheral surface plate 11 are respectively provided with screw member insertion holes 10 a and 11 a in the upper and lower central portions.
The screw member insertion holes 10a and 11a can be used for inserting a connecting screw member 12 (see FIG. 3) for connecting with another unit U that is adjacent in the lateral direction. It can also be used to lock a turnbuckle (not shown) in order to further stabilize the fixing.

According to the unit of this embodiment, in addition to being able to easily perform the connection operation with another unit adjacent vertically and horizontally through the window portion W, the load from the upper unit U loaded is the column portion 1. Even if it acts on, it can make it hard to produce stress concentration in the block 1B for connection, and can support it in the stable state. Furthermore, the coupling force between the units can be sufficiently secured.
Furthermore, since the positioning of the upper and lower units can be performed quickly, it is possible to improve the connection work efficiency between the units.
