Embodiment Construction
[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0034] The invention provides a prefabricated caisson foundation for adding an elevator to an existing building, such as figure 1 or figure 2 As shown, the caisson foundation structure is novel, the design is reasonable, the installation and transportation are convenient, and it is very suitable for the construction needs of existing building sites.
[0035] Such as figure 1 and Figure 5 The prefabricated caisson foundation for adding elevators to the existing building in the shown embodiment 1 includes a hollow box body, which is formed by splicing four corner concrete prefabricated components 1, 2, 3, and 4, and is located on the diagonal The two corner concrete prefabricated components have the same structure, the bottom of the corner concrete prefabricated components ...

The invention discloses a fabricated caisson foundation used for additionally mounting an elevator to an existing building and a construction method thereof. The caisson foundation comprises a hollowcaisson body. The caisson body is formed by splicing two or four corner concrete prefabricated parts. Reserved steel bars stretch out of the bottoms of the corner concrete prefabricated parts correspondingly. Connecting lead screws stretch out of the tops of the corner concrete prefabricated parts correspondingly. Each corner concrete prefabricated part comprises a corner column and corner arms which are integrally formed. The adjacent corner arms and the corner columns are spliced to form the caisson body structure. Splicing planes formed by the adjacent corner arms and corner columns each comprise three splicing surfaces which are perpendicular to one another, water stop grooves with the cross sections capable of being spliced into the rhombic shape are formed in the splicing surfaces correspondingly, first grouting holes communicating with the water stop grooves in the vertical splicing surfaces are formed in the junctions of the corner columns and the corner arms, and second grouting holes communicating with the water stop grooves in the horizontal splicing surfaces are formed in the corner arms located above. The caisson foundation disclosed by the invention is safe and reliable, high in operating efficiency, good in water stop sealing performance and high in bearing capacity, and the caisson foundation can be carried into a construction site flexibly and conveniently.
Description
technical field [0001] The invention relates to a caisson foundation for an elevator, in particular to an assembled caisson foundation for adding an elevator to an existing building and a construction method thereof. Background technique [0002] With the vigorous promotion of the installation of elevators in old buildings, there are many small building distances and spaces, and high terrain, which hinders the smooth progress of construction, and vehicles and cranes cannot enter the site. However, on-site reinforced concrete construction, formwork support, and cast-in-place operations cannot ensure the quality of the project, which puts forward higher requirements for construction personnel. The installation of elevators is a high-risk industry with very strict safety requirements, and the construction of foundation pits is particularly important. Since the outdoor work is greatly affected by the site environment, the construction period is very long, resulting in increased...
