Problems solved by technology

Although the vertical load transfer path is simple, most construction machines are difficult to construct concrete underpinning piles close to the upper vertical components due to size restrictions
[0005] In addition, if the concrete underpinning piles on both sides or around them are not used as temporary supports but as vertical load-bearing members of the proposed basement, it will take up a large plane space, resulting in a waste of underground space

Embodiment 1

[0049] Embodiment 1: a kind of method that is applicable to the underground building of frame structure building, is suitable for such as figure 1 and figure 2 The frame structure building shown has a frame column 1 , an independent foundation 2 and a structural beam slab 3 , and a part of the frame column 1 and the independent foundation 2 are located in the surface foundation soil 4 .

[0050] Carrying out the underground layer-adding method for the concrete building of this frame structure mainly comprises the following steps:

[0051] refer to image 3 and Figure 4 As shown, excavate the surface layer foundation soil 4 above the independent foundation 2 of the building, the boundary is the sideline 6 of the underground garage, and the horizontal and vertical independent foundation 2 below the frame column 1 of the building are all exposed. For the surface foundation soil 4 in the underground garage area, the foundation pit side slope 7 formed during the excavation pro...

Embodiment 2

[0060] Embodiment 2: a kind of building, this building is frame structure, and its structure is as Figure 13 and Figure 14 As shown, the building has a frame column 1, an independent foundation 2 and a structural beam slab 3, and there is a newly added garage below the building;

[0061] Wherein, the newly added garage is constructed by the method described in Embodiment 1.

Abstract

The invention relates to an underground storey-adding method suitable for a frame structure building and the building, and belongs to the relevant technical field of constructional engineering. The method comprises the main steps that A, earthworks of the portions, located above independent foundations, of the frame structure building and an area where an underground garage is planned to build are excavated to enable the foundations of the building to be fully exposed; B, a plurality of concrete underpinned piles are constructed between the independent foundations and on the outer sides of the independent foundations; C, horizontal underpinned beams are fixedly connected with the roofs of the concrete underpinned piles correspondingly; D, concrete column clamping beams are arranged at the two sides of each frame column, and each concrete column clamping beam is connected with the corresponding frame column of the building; E, the original independent foundations of the building are dismantled; G, foundation soil below the building is excavated to the elevation of a bottom plate of the planned garage; H, the bottom plate of the garage, floors of all storeys and a roof are constructed from top to bottom; I, new concrete outer walls are poured on the periphery of the garage; and J, the earthworks are backfilled to the height of the natural ground.

Description

technical field [0001] The invention relates to the related technical field of construction engineering, in particular to a method and a building suitable for underground building of a frame structure building. Background technique [0002] Orderly, reasonable, comprehensive and efficient development and utilization of underground space resources of existing buildings has become one of the most effective ways to expand infrastructure capacity, improve urban comprehensive disaster prevention capabilities, improve land use efficiency and save land resources. According to the requirements of urban planning, most new buildings have considered the development and utilization of underground space. [0003] However, a large number of existing buildings have not designed underground parking lots due to the lack of forward-looking due to historical reasons. With the increase in the number of cars, it is difficult to park. [0004] Using static pressure piles, section steel and origi...
