Description

  The present invention relates to a building having a suitable form when applied to a medium-high-rise to high-rise building, particularly a building for use in an apartment house.

As is well known, as a form of this type of building, for example, as shown in Patent Document 1, a large atrium (void part) is provided at the center of a tower-like building and the top is opened. Things to keep are widespread. In such a building, lighting and ventilation are possible through the atrium to the inside of the building, and it is also advantageous in terms of disaster prevention and plan planning.
JP 7-279448 A

  However, in the above case, it is not always possible to expect sufficient lighting and ventilation to the bottom of the atrium, especially if the building is high-rise, it is inevitable that the bottom of the atrium will generally be a dark atmosphere, Artificial lighting is necessary from the daytime at the bottom of the atrium, and even if a courtyard or light coat is provided there, an environment in which plants grow naturally cannot be obtained. Therefore, as shown in Patent Document 1, there is a proposal that the daylighting is performed by an auxiliary daylighting facility using an optical duct or the like, but in any case, particularly in a high-rise building, a large-scale is intended for daylighting and ventilation. It is considered that there are few advantages in providing the blow-by portion, and an effective improvement measure in this respect has been demanded.

In view of the above circumstances, the present invention is opposed to a building in a form in which the aerial part is open at the center of the tower-like building main body part and the planar shape is substantially B-shaped, with the aerial part interposed therebetween. on both sides of the building body portion, Rutotomoni provided open terrace portion for performing lighting and ventilation to the atrium portion from the outside through both external and atrium section, respectively, each of said open terrace portion, the blow portion It is characterized by being provided as a two-layer atrium while leaving a shared corridor of each layer provided surrounding and surrounding . In particular, it is preferable that an open terrace portion is provided at the bottom of the atrium portion in the building body portion located on the west side of the atrium and an open terrace portion is provided on each floor in the building body portion located on the east side of the atrium portion.

  According to the present invention, in addition to being able to perform daylighting and ventilation to the inside of the upper layer part of the building by the aerial part with the top part opened, the aerial part from outside through the open terrace part provided around the aerial part Daylighting and ventilation are possible by providing the open terrace part on the building main body part facing the both sides of the atrium part between them. In particular, by providing an open terrace on the east side of the atrium, sufficient lighting is possible throughout the atrium from morning to daytime, and by providing an open terrace at the bottom of the west, a moderate west Daylight can be taken.

  1 to 5 show a building which is an embodiment of the present invention. This is the first basement floor and 16 floors above ground, the first basement floor is a common area such as a machine room, the lower floors from the first floor to the third floor are tenant spaces such as stores, and the upper floors above the fourth floor are apartments. This is an example of application to a high-rise building.

  In the building of the present embodiment, as shown in FIG. 1, a top portion is opened at the center of the high-rise portion, and an atrium portion (void portion) 1 having a bottom surface on the top surface of the third floor is provided. As shown in FIG. 3, the planar shape of the high-rise part is formed in a substantially round shape. And the building main-body part 2 which surrounds the atrium part 1 and is provided in the circumference | surroundings is divided into many dwelling units 3, The common corridor 4 which leads to each dwelling unit 3 faces the atrium part 1, and is provided as a corridor. ing.

  In the building of this embodiment, the open terrace part 5 (5a, 5b) is respectively provided in the building main-body part 2 (2a, 2b) of the east and west sides which oppose on both sides of the atrium part 1, These open terraces It is possible to perform daylighting and ventilation from the outside to the blow-through part 1 through the part 5.

  That is, as shown in FIG. 1 and FIG. 2, the second to fifth floors of the building main body 2a located on the west side of the atrium are made up of two layers while leaving the common hallway 4 on the fifth floor. An open terrace portion 5a is provided, and the open terrace portion 5a is open to both the outside and the blow-off portion 1, and is substantially secured as an external space (void portion). As shown in FIGS. 1 and 3, the building body 2b located on the east side of the atrium 1 has an open terrace 5b similar to the open terrace 5a on the west side from the 4th floor to the 16th floor. It is provided as a blow-through of two layers over the entire height.

  By providing such an open terrace part 5 (5a, 5b), as shown in FIG. 1, natural ventilation is evoked between the outside and the blow-through part 1 through each open terrace part 5, and the blow-off part. Sufficient ventilation is provided throughout the entire unit. In addition, since the open terrace portion 5b is provided on the east side over the entire height, the entire atrium 1 can be well-lighted not only in the Chaoyang but also in the daytime, and in the evening in the low-rise part on the west side. A moderate amount of sunlight can be taken from the open terrace portion 5 a to the bottom of the atrium 1. Therefore, it is possible to allow the atrium 1 to function substantially as an external space and to allow the plant to grow naturally, so that it can be effectively used as a courtyard or a light coat.

  In addition, as the handrail 6 provided facing the outside side of the open terrace section 5, a handrail wall is adopted, and the height is adjusted (after ensuring the required height as a handrail). The substantial opening area in the terrace portion 5 can be increased or decreased, whereby the air flow rate in the open terrace portion 5 can be controlled. In that case, by adopting a handrail wall made of transparent glass as the handrail 6, it is possible to adjust only the air flow while ensuring the maximum lighting.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and as long as an open terrace for ventilation and lighting is provided on both sides of the atrium, The location and installation form of the open terrace as well as the scale, application, and plan are arbitrary and various design as long as each open terrace is provided as a two-layer atrium while leaving the common corridor of each layer. It can be changed.

  For example, in the above-described embodiment, the open terrace portion 5 is provided on the east-west surface. However, the open terrace portion 5 can be provided on the north-south surface depending on conditions such as the use and form of the building and the surrounding environment. It is also conceivable that the open terrace portion 5b provided on the east surface over the entire height is provided on the north surface, and the open terrace portion 5a provided on the bottom surface of the west surface is provided on the bottom surface of the south surface. Of course, it is also possible to disperse the open terrace portion only on the desired floor.

  In the above embodiment, as shown in FIG. 1, the seismic isolation structure in which the entire building is isolated and supported by the laminated rubber 7 is adopted.

It is sectional drawing which shows the outline | summary of the building which is embodiment of this invention. It is a top view in the bottom part of a blow-off part. It is a top view in the upper layer part of a blow-off part. It is an elevation view of the west side. It is the elevation of the east side.
