Upward-moving foundation for deep foundation pit engineering elevator

Abstract

The invention discloses an upward-moving foundation, particularly relates to an upward-moving foundation for a deep foundation pit engineering elevator, and belongs to the technical field of building of building engineering construction equipment accessories. The upward-moving foundation for the deep foundation pit engineering elevator which is relatively simple in construction, relatively low in cost, safe and environmentally friendly is provided. The upward-moving foundation comprises an original foundation of the engineering elevator, an upward-moving truss assembly and a closed protection assembly, and the top face, arranged in a deep foundation pit through the original foundation of the engineering elevator, of the upward-moving truss assembly forms a feeding platform for conversion from horizontal stopping to vertical transportation of a cage of the engineering elevator. A gap in the top of the upward-moving truss assembly is closed through the closed protection assembly.

Description

technical field [0001] The invention relates to an upward return foundation, in particular to an upward return foundation used for elevators in deep foundation pit engineering, and belongs to the technical field of building construction equipment accessories. Background technique [0002] Construction elevators or material hoists are indispensable as a kind of vertical transportation equipment in the construction of construction projects, especially the vertical transportation of materials in all processes of civil high-rise and super high-rise buildings from masonry construction to related decoration, electromechanical installation, etc. Both require construction elevators or material hoists to complete. At the same time, due to the development of modern construction fields toward high fields and underground spaces, deep foundation pits can be seen everywhere.

Problems solved by technology

At the same time, due to the development of modern construction fields toward high fields and underground spaces, deep foundation pits can be seen everywhere. In the general layout of material transportation, tower cranes with a wide horizontal radiation area must first be considered, and tower cranes often occupy the most favorable plane. And space location, and the use of the general layout must ensure the tower crane, construction elevator, safe distance between structures, the space distance necessary for installation and dismantling, and the space terrain conditions necessary for material transfer. The arrangement of cranes is often very unfavorable. Some single buildings under the condition of deep foundation pits may even be unable to arrange vertical transportation construction elevators due to the above various conditions, or the tower cranes cannot be dismantled later after the arrangement.

[0003] At present, there are usually two ways to arrange construction elevators in deep foundation pits including basement projects: one is that construction elevators and tower cranes are arranged on both sides of the building, tower cranes are arranged on the basement floor, and construction elevators are arranged on the basement roof or floor. This kind of layout often has sufficient space for the layout of construction elevators on the sidelines of single buildings and basement outdoors, and at the same time has very strict requirements on the topographical conditions of structural layout and logistics transportation; It can only be arranged around the fertilizer tank of the deep foundation pit. This arrangement must transform the elevator foundation into a high-volume concrete foundation, which greatly increases the amount of concrete engineering, and is also extremely unfavorable for the crack resistance quality control of the large-volume concrete foundation. At the same time, due to the volume of the foundation Greatly increasing the safety of its underground foundation has also caused hidden dangers. Due to the occupation of space, it is also unfavorable for the interspersed construction of the surrounding processes of the fertilizer tank, such as basement waterproofing, elevator unloading platform protective frame, and protective shed erection.
