Description

  The present invention relates to a multi-storey residential building with an underground floor, which has an underground floor and a second or third ground floor is constructed on a frame constituting the underground floor.

  As a multi-storey residential building, the basement or the ground floor is generally made of steel concrete (RC structure), and the RC basement or ground floor is built on the ground floor or ground. A multi-storey residential building with or without an underground floor constructed by constructing the second-floor frame by on-site construction is well known. Such multi-storey buildings are often found in so-called built houses, etc., without needing to present patent documents, non-patent documents, and the like.

  The above-mentioned conventional general multi-storey residential buildings are constructed entirely on-site by bringing a huge number of building materials to the site, both of the RC basement or the ground first-floor housing and the wooden ground-floor housing. Because it must be built sequentially from the lower floor to the upper floor, it not only requires a lot of on-site work and complicated construction processes, but also involves vibrations and noise, especially in densely populated houses such as the city center Then, there is a problem of having a great deal of trouble and bad influence on the surrounding houses.

  In addition, in a conventional multi-storey residential building, in order to provide sufficient strength and earthquake resistance sufficient to bear the weight of the upper wooden floor frame to the RC basement floor or the ground first floor frame. The RC basement or the ground first-floor housing itself must have a large strength structure, and it also requires a solid foundation to support them against the ground, and the construction period is long as described above. Synergistically, the total construction cost of the entire residential building will be very high.

  In addition, in conventional multi-storey residential buildings, disasters such as earthquakes occurred so that the upper wooden floor frame and even the RC frame were collapsed or destroyed to a state close to collapse. In this case, because it is not possible to secure a place to evacuate inside the building, the occurrence of human damage due to the disaster is unavoidable unless it escapes to the outside of the building at the same time as the disaster occurs. There was a problem that the building materials that collapsed before the evacuation ended could fall or fall, and that they could not escape or were injured by the falling materials.

  The present invention has been made in view of the above circumstances, and it is possible to reduce the total construction cost by shortening the construction period and reducing the construction cost, and significantly improve the proof stress and the earthquake resistance while ensuring a sufficiently large living space. In addition, it aims to provide a multi-storey residential building with a basement floor that can secure temporary evacuation sites and minimize human damage in the event of a disaster such as a major earthquake. .

  In order to achieve the above object, a multi-storey residential building with a basement floor according to the present invention is a wall in which a metal outer plate is fixed to the outside of a plurality of core steel frames arranged in parallel at a predetermined interval on the same surface. The structure, ceiling structure, and floor structure are assembled and manufactured at the factory, with a ramen structure in the beam-to-beam direction and a seismic-resistant panel structure in the direction of the beam, and a vertical cross-sectional shape with a roughly rectangular shape, or a structure that is divided horizontally or vertically. By constructing a metal unit housing composed of a pair of split bodies with a substantially U-shaped vertical cross section that allows the ends of the body to be butt-joined so that the whole or most of it is buried underground The basement and reinforcing concrete walls are continuously formed integrally on the bottom and outer periphery of the underground unit of the metal unit frame that is constructed, and the basement metal unit. At the top of the enclosure, the The ground floor is constructed by stacking and joining metal unit housings of the same or almost the same specifications as the genus unit housing, and the upper floor wooden housing is above the metal unit housing for the ground floor. It is characterized by being built.

  According to the present invention having the above-described configuration, the same or almost the same specification metal unit housing assembled and manufactured at the factory is brought into the field and installed, and stacked and joined in the vertical (vertical) direction, and the construction is performed on the upper part. A multi-storey residential building with a basement floor, one ground floor, and two or more floors above ground, with simple and very few on-site construction, such as building a wooden structure for upper floors Can be constructed in a short period of time, and the RC building basement or ground first-floor frame and the upper-layer wooden frame above it have all been constructed in a conventional manner. Compared with a storey residential building, the construction period can be significantly shortened and the construction cost can be greatly reduced, and inconveniences and adverse effects on the surrounding housing due to noise and vibration can be greatly reduced.

  In addition, not only the strength and quality of the metal unit housing for underground floors and the metal unit housing for ground floors have been stabilized by assembly at the factory. Since it is an earthquake-resistant panel structure and has a strong proof stress, it is possible to construct the basement cabinet on the ground floor and above it by simply providing a simple foundation at the bottom of the basement cabinet. The multi-storey residential building with underground floors can be effectively used as a foundation for stable support of the upper floor wooden frame, combined with the shortening of construction period and reduction of construction costs as described above. The total construction cost can be significantly reduced compared with the conventional general construction cost.

  In addition, the entire base unit for basement floor and ground floor unit that are stacked and joined in the vertical direction is a ramen structure in the beam-to-beam direction and an earthquake-resistant panel structure in the cross-beam direction, so that it does not collapse even in the event of a large earthquake. Since it has excellent strength and seismic strength, it is possible to effectively use the ground floor or underground floor as a temporary emergency evacuation site in the event of a disaster such as an earthquake. Human damage at the time of occurrence can be minimized.

  In addition, the base and reinforcing concrete walls are integrally and continuously formed at the bottom and outer periphery of the underground unit in the basement metal unit housing, so that the basement metal unit housing buried underground The required rust / corrosion performance can be ensured by simple on-site construction. Therefore, no expensive thick-film rust / corrosion coating work is required, both in terms of materials and work technology. There is an effect that the durability of the entire building can be economically realized.
