Description

  The present invention relates to a basement with a dry area, and more specifically, three wall structures in which a core steel frame arranged at a predetermined pitch interval is used as a shaft assembly, and a metal plate is fixed to the outer surface side of the core assembly steel frame. Sheets are arranged and connected in a U-shape in plan view at the factory production stage to form a metal dry air unit, and this metal dry area unit protrudes outward at the end of the metal underground frame at the construction site. The present invention relates to a basement with a dry area, which is formed by forming a dry area that is connected to the basement and opens to the ground by being integrally connected in a state.

  In this type of basement with a dry area, even in the basement, the same ventilation, lighting and openness as the ground floor can be obtained, and even under ground conditions where there is no space to secure a garden etc. on the ground, gardening and It has the feature that it can be used for various purposes such as enjoying as a miniature garden.

  By the way, in the basement with a dry area, a large earth pressure acts on the three wall structures in the metal dry area unit forming the dry area in an underground state. In particular, among the three wall structures in the dry area unit, the core that is the member of the structure is the largest earth pressure acting on the wall structure that is located farthest from the underground structure and faces the end surface of the underground structure. Steel frames and metal plates are easily bent and deformed. As means for ensuring the strength to withstand the pressure with bending deformation of such structure members, conventionally, as shown in FIG. 5, the wall structure 21A located on the outermost side in the dry area unit 20, Each of the wall structures 21A, 21A, 21B, 21A, 21B, 21B, 21B, 21B by connecting the braces 22 and 22 diagonally across the upper ends of both side wall structures 21B and 21B that are integrally connected to the underground frame 23 and extend outward A configuration has been adopted in which the soil pressure F acting on 21B is in a state of stress distribution as shown in FIG. 4B and ensures sufficient strength to withstand the soil pressure (for example, non-patent Reference 1).

  However, in the case of the conventional means as described above, since the two braces 22 and 22 are located in a state where the upper open space of the dry area DE is skewed, the field of view is obstructed by an obstruction and the features of the dry area DE are characteristic. The feeling of opening and lighting are impaired. Moreover, since the braces 22 and 22 exist in the ceiling equivalent part of the dry area DE, an effective space that can be used for various purposes such as gardening and a miniature garden is naturally restricted, and improvements in these points are desired. Has been done.

  The present invention has been made in response to the above-mentioned demands, and does not impair the feeling of openness and lighting as a dry area, and while making the effective space for multi-purpose utilization such as gardening as wide as possible, It aims at providing the basement with a dry area which can ensure sufficient proof strength with respect to.

  The basement with a dry area according to the present invention devised to achieve the above object uses a core steel frame arranged at a predetermined pitch interval as a shaft assembly, and a metal plate on the outer surface side of the core assembly steel frame A metal dry airer unit is constructed by arranging and connecting three wall structures fixed to each other in a U-shape in plan view in the production stage, and this metal dry area unit is made into a metal underground enclosure at the construction site A basement with a dry area, which is connected to the end of the basement in an outwardly projecting state to form a dry area that is open to the ground in connection with the basement, each wall in the metal dry area unit A shape steel having a bending strength sufficient to withstand the earth pressure acting on the dry area unit is fixed to the upper end portion of the core steel frame for the shaft of the structural body in a cap shape.

  According to the present invention having the above-described characteristic configuration, the core material for the shaft assembly of each wall structure can be obtained without diagonally bridging and fixing between the wall structures in the metal dry area unit. By simply fixing the shape steel to the upper end of the steel frame in the form of a coping, it is possible to ensure sufficient strength to withstand earth pressure. Therefore, not only can the number of components in the dry area unit be reduced and the unit manufacturing cost can be reduced, but also an open area with no obstruction can be formed at the top of the dry area. In addition to being able to sufficiently obtain daylighting and a feeling of openness, the dry area connected to the basement can be used for various purposes and effectively as a space for gardening or a small garden, for example.

  In the basement with a dry area according to the present invention as described above, the metal basement unit integrally connecting the dry area units may be constructed sequentially at the construction site, and in particular, according to claim 2. As described above, the metal underground frame has a pair of left and right wall structures, a ceiling structure, and a floor structure in which a core steel frame is used as a shaft assembly, and a metal plate is fixed to the outer surface side of the core assembly steel frame. When using an underground structure constructed in a seismic wall structure by joining and joining any number of metal underground units assembled into a ramen structure at the factory production stage at the construction site, both are of high quality and high quality at the factory. As mentioned above, the dry area unit and underground unit, which can be manufactured with precision, are transported to the construction site, buried underground, and joined and connected. With entire basement containing dry area to be constructed efficiently and economically with, it is possible to realize a further increase and improvement in the earthquake resistance of the antistress strength against earth pressure.
