Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the structure of reinforced steel and steel-framed concrete buildings such as condominiums.

(Prior art) In general, the structure of this type of building is such that the entire building is composed of a rigid-frame structure or a continuous shear wall structure, and the central part of the building is used as the so-called core part where elevators and other common facilities are concentrated. Living rooms are arranged outside of it.

(Problems to be Solved by the Invention) However, in the conventional building structure described above, pillars and beams have to be installed even in the living room area, which limits the housing unit plan and floor plan, and reduces the cost and construction planning. This was not only undesirable, but also detracted from the quality of the room and its aesthetic appearance.

Therefore, the present invention provides a building structure that can improve the above-mentioned problems.

(Means for Solving the Problems) The structure of the building according to the present invention consists of a three-dimensional rigid frame structure on the inside of the building, which is mainly used for the core part, etc., and a structure that surrounds this three-dimensional rigid frame structure and its outside. In this way, the tube structure part, which is formed by a rigid frame structure using a short span frame, is connected with a slab of equal thickness, which has no beams and whose middle part is not supported by columns.

As a result, for horizontal external forces acting on the building due to wind, earthquakes, etc., the equal-thickness slab only transmits the horizontal force between the inner three-dimensional rigid frame structure and the outer tube structure. , a column-free space without beams or columns is formed between the upper and lower equal-thickness slabs between the two structural parts.

(Example) Examples of the present invention will be described below based on the drawings. Figure 1 is a schematic plan view of the overall structure of the building, with the inside consisting of a three-dimensional rigid frame structure part 1, and the outside consisting of a tube structure part 2 surrounded by a rigid frame structure of a short span frame. The three-dimensional rigid frame structure part 1 and the tube structure part 2 are connected by a slab 3 of equal thickness.

As shown in FIG. 2, the three-dimensional rigid frame structure part 1 has a pillar 4, a longitudinal beam 5, and a transverse beam 6 rigidly connected in a crosswise manner, and a floor slab 7 is stretched. It has a normal three-dimensional rigid frame structure.

Further, the tube structure portion 2 is an outer shell tube surrounded on four sides in a birdcage shape by a short span frame that rigidly connects columns 8 and beams 9 arranged in a short span to form a rigid frame structure. It is made up of.

A slab 3 of equal thickness is constructed in such a manner as to connect the columns 4 of the three-dimensional rigid frame structure section 1 and the columns 8 of the tube structure section 2. This equal thickness slab 3
is a structure in which there is no beam between each of the structural parts 1 and 2, and the intermediate part is not supported by columns, so the horizontal load applied to each of the structural parts 1 and 2 is transmitted by the equal thickness slab 3, and A column-free space 10 without beams or columns is formed between the upper and lower equal-thickness slabs 3, 3.

Note that the beam 9 of the tube structure portion 2 is shown in Fig. 2a.
Although it may be installed vertically in the same way as the beam 6 of the three-dimensional rigid frame structure part 1, it is easier to use an inverted beam structure as shown in FIG. 2b.

The building constructed as described above utilizes the inner three-dimensional rigid frame structure part 1 for the core part where elevators and other common facilities are installed, and for the part of the living room where the restrictions of columns and beams are not a problem, and the above-mentioned uniform thickness slab The column-free space 10 between 3 rooms is not restricted by beams or columns as in the past, so it can be freely divided by walls of non-structural materials and used as a living room with no exposed beams or columns inside. I can do it.

In addition, the equal thickness slab 3 absorbs only the horizontal force between the three-dimensional rigid frame structure part 1 and the tube structure part 2 formed by the rigid frame structure formed by the short span frame against horizontal external forces such as wind and earthquakes. They work together to create a living room with excellent earthquake resistance.

Furthermore, by adopting the reverse beam structure as shown in FIG. 2b, the equal thickness slab 3 can be used as a balcony with a good view.

(Effects of the Invention) As is clear from the embodiments described above, in the building structure of the present invention, the column-free structure is formed between the upper and lower equal-thickness slabs that connect the outer tube structure part and the inner three-dimensional rigid frame structure part. By utilizing the available space, you can create living rooms with high livability and aesthetics based on a free housing plan.

In addition, the above-mentioned uniform thickness slab without beams and columns can be easily constructed by setting the thickness arbitrarily to obtain the desired rigidity and soundproofing performance, and the uniform thickness slab can be constructed with base material and finishing material. The installation work can be carried out extremely easily.

Furthermore, because the slab is of equal thickness without a beam, there is no need to match the position of the mating member and the beam, unlike in the case of a slab with floor beams, making construction easier.
