It has a schematic configuration in which a duct 8 is arranged between these auxiliary beams 7.

Next, to explain these details, in this embodiment, the plurality of pillars 5 constituting the structural unit U are used as a set of four, and each pillar 5 is connected to the space between adjacent pillars 5. They are erected parallel to each other so that the spacing is constant.

Each of the main beams 6 is formed to have a length substantially equal to the interval between the columns 5, and is disposed between the upper ends of adjacent columns 5 along the horizontal direction,
By connecting both ends to the pillars 5, the pillars 5 are interconnected.

In addition, the auxiliary beam 7 has two parts per column 5.
In this embodiment, it is installed so as to be located on the extension line of the main beam 6. The length of the auxiliary beam 7 is set to approximately half the length obtained by subtracting the width of the duct 8 from the distance between the pillars 5.

On the other hand, in this embodiment, a cross-shaped small beam 9 is provided inside the main beam 6 arranged in a rectangular shape to interconnect the intermediate portions of these in the longitudinal direction.

A plurality of structural units U configured in this manner are connected to the main beam 6 and the auxiliary beam 7 of each structural unit U.
are located on the same line in each of the two orthogonal directions within the same plane, and the spacing between the columns 5 of adjacent structural units U matches the spacing between the columns 5 of the structural units U. By erecting the auxiliary beams 7 in this way, due to the relationship between the dimensions of the auxiliary beams 7, the width of the duct 8, and the distance between the structural units U, there is a gap between the adjacent auxiliary beams 7, in other words, the structural units U The structure 4 is constructed with a gap G corresponding to the width of the duct 8 formed around it, and
A space for installing the duct 8 is secured.

A duct 8 is disposed between the auxiliary beams 7, and the duct 8 is connected to the auxiliary beams 7, and a continuous A structure unit U is installed at the outermost part by attaching a beam (not shown).
By interconnecting these, the structure 4 of this embodiment is formed. In addition, each structure unit is
As shown in FIG. 2, the floor slabs on each floor form an integrated structure, and the structure is naturally designed to have at least the same strength as the conventional structure.

Structure 4 of this example formed in this way
As shown in FIG. 2, the lower surface of the duct 8 is held at approximately the same level as the lower surfaces of the main beam 6 and the auxiliary beam 7, and protrusion into the indoor space is prevented or suppressed.

As a result, when the required amount of indoor space is secured as before, the floor height of the building can be made smaller than before, as shown by the chain line in Figure 2, and the building structure and finishing costs are reduced. etc. can be reduced.

In addition, by changing the length of the auxiliary beam 7, the stress generated at the ends and center of the main beam 6 can be easily adjusted, and the size of the installation space for the duct 8 can be easily changed, thereby increasing the design freedom.

On the other hand, in this embodiment, since the cross-shaped small beams 9 are provided between the main beams 6 of the structural unit U, the stress generated in the structural unit U is reduced in two orthogonal directions along each main beam 6. can be made the same, which also simplifies the design.

It should be noted that the various shapes and dimensions of each component shown in the above embodiments are merely examples, and can be variously changed based on design requirements and the like.

"Effect of the invention" As explained above, the structure of the building according to the invention consists of a plurality of columns and a plurality of main pillars arranged in a rectangular shape when viewed from above and interconnecting the pillars. A structural unit is formed by a beam and an auxiliary beam protruding from each of the pillars along an extension line of each main beam, and a plurality of the structural units are arranged at intervals between the auxiliary beams. further, a continuous beam is attached between the auxiliary beams facing the outside of the outermost structural unit to interconnect the outermost structural units, and It is characterized by having each structural unit integrated with a floor slab, and equipment such as air conditioning ducts and electrical piping installed in the ceiling (floor) of the building can be connected between the structural units. By installing it between the beams, it is possible to prevent or suppress the lower surface of the equipment from protruding into the indoor space from the lower surface of the main beam or auxiliary beam, thereby reducing the floor height of the building. result,
In particular, the floor height efficiency is improved, and it is possible to reduce building frame costs and finishing costs, and by changing the length of the auxiliary beams, stress generated at the ends and center of the main beams can be reduced. In addition to facilitating adjustment,
