Description
Technical Field
[0001] The utility model relates to the technical field of building structures, in particular to a building structure system close to a land red line. Background Art
[0002] When most houses are constructed, they are usually built a certain distance away from the land redline to meet planning conditions and facilitate the laying of underground pipelines. With the rapid development of urban construction in recent years, the shortage of urban construction land has become increasingly prominent, which sometimes leads to the need to move buildings to the edge of the land redline to maximize the layout of limited underground buildings. In particular, buildings need to be built close to the land redline and there is a large height difference between the inside and outside of the redline. At this time, the construction parties will set up traditional retaining walls at the height difference according to conventional practices, and at the same time move the load-bearing columns and structural foundations of the ground buildings inward a large distance to avoid the area affected by the retaining wall, so that the retaining wall and the building are separated from each other.
[0003] The main shortcomings of this conventional approach are:
[0004] (1) Generally speaking, the inward movement of the outermost row of load-bearing columns of ground buildings will seriously affect the internal functional layout and use of the building, making the building unable to meet the use requirements of related functions and the requirements of the overall appearance effect.
[0005] (2) The greater the height difference between the inside and outside of the site red line, the greater the distance that the outermost row of load-bearing columns of the building move inward, which means that the load-bearing structure needs to have a larger cantilever. The larger the cantilever, the more complex the load-bearing structure is in terms of force, which increases the difficulty of construction and makes it difficult to ensure construction quality, which has an adverse impact on building safety.
[0006] (3) In order to ensure that the foundation of the building is not affected, it is necessary to first construct a retaining wall at the red line of the land. Only after the retaining wall is completed and the foundation pit is backfilled to the ground can the foundation of the ground building be constructed. The entire construction process is complex and the construction period is long. Utility Model Content
