Abstract

(57) [Summary] [Purpose] The opening of a building is designed so that the outer perimeter beam, which is the upper beam in a living room, does not appear under the slab, and the parapet can be formed on the uppermost perimeter beam. Give a feeling of openness to the parts, and if the frame design is adopted as the exterior design of the building, the exterior design will be unified. [Structure] The outer perimeter beams 2 on each floor of the building were all reverse beams, and the parapet B was formed by the uppermost perimeter beams 2.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building having a reverse beam.

[0002]

2. Description of the Related Art In a normal building constructed of a reinforced concrete structure or the like, a beam provided as a frame structure between columns is integrated with a slab so as to project below the slab. However, such a structure in which the beam structure is secured under the slab has the following problems depending on the purpose of the building. For example, as shown in FIG. 7, in a building 1 as an apartment house, in an opening b facing a balcony a, an upper beam c of the floor is usually used because of the relationship between the floor height and the beam formation.
Is arranged so that it appears downward, and therefore, there is a problem that the occupants are likely to give a feeling of pressure when looking at the balcony side.

Further, the following problems may occur in the exterior design of the building. As shown in FIG.
One of the methods widely used as an exterior design method in a low-rise building 1 is a frame design that emphasizes columns d and beams e on the outer peripheral surface side of the building. In the case of such a design, the parapet f is further extended along the beam e on the outermost periphery.
However, there is a problem in that the frame at the top is larger than the other frames, and the design cannot be unified.

In view of the above circumstances, the present invention is to prevent the outer peripheral beam serving as the upper beam from appearing under the slab in a living room or the like, and to enable the parapet to be formed by the uppermost outer peripheral beam. The object is to give a feeling of openness to the opening of the building, and to make it possible to unify the exterior design when a frame design is adopted as the exterior design of the building.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems and is characterized in that all the perimeter beams on each floor of the building are reverse beams, and a parapet is formed by the top perimeter beams. It is intended to solve the above problems by providing a building having a beam. Further, another invention is a building having a reverse beam, characterized in that a peripheral beam located between required columns on the outer peripheral side of the building is a reverse beam, and a window is provided under the peripheral beam, It provides an opening where the upper beam does not appear for the required living room on the exterior side of the building.

[0006]

In the present invention, the upper beam cannot be seen from the inside of the building in the portion where the outer peripheral beam is a reverse beam, and the upper outer beam is used as a parabolic beam. It becomes easier to unify the design when the exterior is made into a frame design.

EXAMPLES The present invention will be described in detail with reference to the examples shown in FIGS. 1 and 2 show a first embodiment. The building 1 in this embodiment is a low-rise single dormitory, and a frame design is adopted in which the outer peripheral beams 2 and the outer peripheral pillars 3 are emphasized in the appearance of the building. In this building 1, as shown in FIG. 2, each of the outer perimeter beams 2 along the living space on each floor is provided as a reverse beam so that the slab 4 can be beamed upward. Has been. Thus, in the living room A having the opening 6 in which the window 5 is arranged between the upper and lower outer peripheral beams 2, the outer peripheral beam 2 cannot be seen above the opening 6 from the living room A side, and a feeling of openness is provided. You will get it. Further, in the uppermost peripheral beam 2, the peripheral beam 2 itself forms the parapet B.

FIGS. 3 to 6 show a second embodiment, which is an example in which the building 1 is constructed as an apartment house, in which 6 dwellings C are arranged side by side, and every two dwellings are on the same side. A shared space is located in. Out of the outer perimeter beams 2 connecting the six houses C, the outer perimeter beams 20 located between the pillars that lie between the two adjacent houses are provided as reverse beams. Further, in each door, the surface side having the outer peripheral beam 20 is formed as an opening 6. FIG. 4 shows a plane per unit. As shown in FIG. 4, in a portion where the opening 6 is formed in one span, a sliding door 7 is attached so that the door can be moved in and out of the balcony D. Has a conventional upper beam. Further, in the part where the pillar is divided with the adjacent door, that is, in the part where the outer peripheral beam 20 is passed, the window 5 is arranged between the upper and lower outer peripheral beams 20 as shown in FIG. The opening 6 is formed and provided in a bay window type. In the opening 6 provided with this bay window, the upper beam does not exist as in the first embodiment, and an upper space with a feeling of openness is obtained, and in comparison with the opening having the upper beam, Light from outside will reach the back of the room.

The arrangement relationship between the balcony D and the outer peripheral beam 20 is not limited to the arrangement of the balcony D on the outer side of the outer peripheral beam 20 as described above.
As shown in FIG. 5, the balcony D may be arranged inside the outer perimeter beam 20, and the opening 6 formed by attaching a sliding door or the like may be formed so as to face the balcony D.

[0010]

As described above, a building having a reverse beam according to the present invention is characterized in that all the outer perimeter beams on each floor of the building are reverse beams, and the parapet is formed by the uppermost perimeter beams. It is a thing. As a result, when an opening is formed between the upper and lower outer peripheral beams, the conventional upper beam does not exist above the opening, and the opening with a feeling of openness can be obtained by eliminating the feeling of pressure from the upper side. Will be available. In addition, when the outermost beam on the top of the building has a shape that projects upward, and when a parapet is formed by this outer beam and the frame design method is used as the design motif of the building, the uppermost frame is It will be easier to harmonize with the frame part, and it will be easier to unify the exterior design.

Another aspect of the present invention is characterized in that an outer peripheral beam located between required columns on the outer peripheral side of a building is a reverse beam, and a window is provided below the outer peripheral beam. As a result, the window between the upper and lower outer beams, which are reverse beams, makes it possible to provide an opening that is a bay window-like opening and does not have an upper beam. Is played.
