Problems solved by technology
During the construction of the existing sunken foundation with an elevator, the foundation pit is excavated on site, the cushion is poured, the base plate and the wall formwork are supported and installed, the steel cage is arranged and installed, and the concrete is poured. Not only the construction period is several months, but the construction space The narrowness leads to low work efficiency and waste of materials. The construction operation also interferes with the normal life of the residents in the existing building area. The construction workers and residents are prone to market conflicts, and even affect the construction period.

Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] Such as figure 1 , figure 2 , image 3 As shown, a prefabricated submerged foundation with an external building elevator includes a wall 1 , a bottom plate 2 and a cushion 3 . The cushion layer 3 is poured on-site with plain mortar in the foundation pit; the base plate 2 is flat, and the base plate is placed on the cushion layer plain mortar that has not yet solidified in the cushion layer 3 by sitting on the base plate, so that the base plate and the cushion layer The contact is tight, so that the various loads on the base plate can be evenly transferred to the surrounding foundation. The enclosure wall 1 is a rectangular frame, which is fixed on the upper surface of the bottom plate by means of reinforced mortar anchorage, and its exterior is filled with soil layer 4 .

The invention relates to an externally-added building elevator prefabricated type sinking foundation. The externally-added building elevator prefabricated type sinking foundation comprises an enclosing wall, a base plate and a cushion layer. The cushion layer is arranged in a foundation pit by pouring plain mortar on site; the base plate is in a panel shape and mounted on the cushion layer by bedding; the enclosing wall is of a rectangular frame structure and connected with the upper surface of the base plate by steel rebars and high-strength mortar. The sinking foundation is reasonable in design, simple in structure and convenient to assemble; the components of the externally-added building elevator foundation can be prefabricated by disassembling, then transported to the site and assembled into a whole, so that the construction period can be effectively shortened, the labor and materials of site operation can be saved, the cost can be lowered, the engineering quality can be guaranteed; moreover, the disturbance to the normal life of residents in existing buildings can be reduced as far as possible and certain economic benefits can be created.
Description
technical field [0001] The invention relates to a building foundation, in particular to a building foundation with an elevator, in particular to a prefabricated sunken foundation with a building elevator. Background technique [0002] At present, my country has entered an aging society. In the existing multi-storey residential buildings below 7 floors, there are 100-200 million elderly people over the age of 60. These existing multi-storey buildings do not have elevators, and it is very inconvenient for the elderly to go up and down. In recent years, the government has vigorously promoted livelihood projects and promoted the installation of elevators in multi-storey residences in major cities. During the construction of the existing sunken foundation with an elevator, the foundation pit is excavated on site, the cushion is poured, the base plate and the wall formwork are supported and installed, the steel cage is arranged and installed, and the concrete is poured. Not only t...
