BACKGROUND OF THE INVENTION
  The present invention relates to a structure that can be installed indoors or outdoors and used for various purposes.
[0002]
[Prior art]
  In order to form spaces for various purposes such as conversation spaces, rest spaces, office spaces, conference spaces, and private booths in and out of the room, an open type with the upper end of the column group connected by a horizontal beam (transverse beam) A structure has been proposed (for example, Patent Document 1).
[0003]
  In this patent document 1, the horizontal beam is formed in a groove shape having a downward opening, and the end of the horizontal beam is fitted into the laterally protruding portion of the connecting metal from above and fastened with screws.
[0004]
  Moreover, there is a partition device as a typical example of the structure that partitions the space, and this partition device includes a type using a column and a type not using a column. An example of a partition device that does not use a column is described in Patent Document 2.

[0006]
[Problems to be solved by the invention]
  If the horizontal beam is fitted from above into the laterally protruding portion of the connection fitting as in Patent Document 1, the horizontal beam can be connected in a state where the column is erected at a predetermined position. There is an advantage that exchange is also easy.
[0007]
  However, since the horizontal beam as a whole has a groove shape with a large opening downward, the strength is inferior, and the groove is too conspicuous and the aesthetics may be inferior. Further, there is a step between the tip of the laterally protruding portion of the connecting metal and the inner bottom surface of the horizontal beam, and there is a risk that the aesthetics may deteriorate due to the fact that this is visible from below. One object of the present invention is to improve such problems.
[0008]
  On the other hand, for example, as a form of use of the space in the office, in addition to the closed type work space in which the individual is surrounded by a partition, an open type work space where a large number of people share the space, an eclectic work space of both, There are cases where working styles are diversified, and it is desired to use them in different ways of use, such as attaching or removing a wall unit to one type of structure.
[0009]
  In that case, it is necessary to secure the mounting strength of the wall unit. Another object of the present invention is to meet this demand.
[0010]
[Means for Solving the Problems]
  Main departureTomorrowA horizontal beam is connected to the upper end of the support via a connecting bracket, and fixtures such as tables and chairs or wall units are attached to the support, or surrounded by three or more supports.TheBy setting up a table at the place, a space for some purpose is formed indoors or outdoors.forConcerning the structure.
[0011]
  And the claim 1TomorrowThe horizontal beamIs insideIt has an upper plate and a lower plate that are formed in a hollow shape, and a lower opening is formed at the end of the horizontal beam by notching the end of the lower plate in this horizontal beam over an appropriate range.ButFormationHas beenOn the other hand, the connecting bracket extends horizontally and horizontally from the column andSaidDownward openingDownIt has an arm that fits fromSaidarmWhenScrew horizontal beamConclusion withis doing.
[0012]
  Origin of claim 2TomorrowThe horizontal beam according to claim 1.A pair of downward projections projecting downward from the lower plate is formed on both sides of the lower plate, and thus a downward opening groove is formed by the lower plate and the pair of downward projections. On the other hand, a wall unit is fixed to the support column, and an upper end portion of the wall unit is fitted into the downward opening groove of the horizontal beam from below.
[0013]
  Origin of claim 3TomorrowIn Claim 1 or Claim 2, while the said support | pillar is formed in the hollow shape, the said connection metal fitting is being fixed to the upper end of this foot | leg part inserted in the hollow part of a support | pillar from the upper part. A hollow square arm,SaidThe lower surface of the arm in the connecting bracket and the lower surface of the lower plate in the horizontal beamTogaAlmost the same surfaceIt has become.
[0014]
[Operation and effect of the invention]
  According to the present invention, since the horizontal beam is formed in a hollow shape, the strength can be secured. In addition, since the horizontal beam does not have an excessively large downward opening groove, it is excellent in aesthetics even when the lower surface of the horizontal beam can be viewed from below like an open structure without a wall unit or the like. ing.
[0015]
  In addition, the structure is composed of a pillar and a horizontal beam, and not only can it be used independently as an open-type space forming means, but also by attaching a wall unit to adjacent pillars. It can also be configured.
[0016]
  And when comprised like Claim 2, when attaching a wall unit to a support | pillar, since the upper end of a wall unit and a horizontal beam are fitting, it is high with respect to the external force which acts on the wide surface of a wall unit The resistance can be maintained and the mounting strength can be significantly improved. Moreover, since the horizontal beam has the same appearance as the wall unit headboard, it is excellent in aesthetics.
[0017]
  According to the third aspect of the present invention, since the foot portion of the connecting metal fitting is inserted into the hollow portion of the support column, the foot portion may have a hollow shape or a rod shape, so that rigidity can be secured and strength can be maintained. In addition, since the lower surface of the arm in the connection fitting and the lower surface of the lower plate in the horizontal beam are aligned, the arm does not stand out and is particularly excellent in aesthetics.

  This embodimentThe connection structure between the columns 1 and 2 and the horizontal beam 3 inBasically, it is the same as that of the first embodiment, and only the forms of the support columns 1 and 2 and the connecting bracket 39 are different. Therefore, detailed description is omitted.
[0086]
  An open type structure as in the second embodiment and a closed type structure having a wall unit 49 as in the third embodiment using the support columns 1 and 2 having the rectangular inner member 5. Although it can be assembled, the horizontal beam 3 is fitted to the arm 41 of the connecting bracket 39 from above, so that the horizontal beam 3 can be fixed after the wall unit 49 is previously attached. It is easy to speak.
[0087]
  Further, when the wall units 49 are connected to each other using the bolts 68 that are operated to rotate from above as in the embodiment, or the wall units 49 are connected to the intermediate frame 54, the columns 1 and 2 are fixed to each other. It is easy to remove the wall unit 49 while standing in the position and make it an open type, or from an open type to a closed type, or to simplify the wall unit 49 to another structure. There is an advantage that can be done.

  (4) .Other
  The present invention can be embodied in various ways other than the above embodiment. For example, it can be arbitrarily changed according to the cross-sectional shape and application of the support column and horizontal beam. It goes without saying that a closed type structure (for example, a hexagonal structure in plan view) can be formed by using a support having a triangular inner member as in the first embodiment.
[0089]
  In addition, it is possible to apply a horizontal beam to a support | pillar via the connection bracket provided with a foot | leg part and an arm, and to fit a horizontal beam and a wall unit also to a horizontal beam which is not hollow. .
