Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a tower crane foundation and bottom structure at the post-pouring strip location. Background Technology

[0002] Traditional tower crane foundations are difficult to position when encountering post-cast strips. The conventional approach is to avoid placing the foundation at the post-cast strip location. However, sometimes site constraints prevent relocation, making placement difficult. A difficult-to-position tower crane foundation means it's difficult to install the required tower crane, hindering hoisting operations. Currently, there is a need to develop a new type of tower crane foundation that can be positioned at the top view of the post-cast strip for tower crane installation during construction. Simultaneously, a new base structure needs to be developed to integrate with the tower crane foundation, forming a stable structure. Utility Model Content

Furthermore, the pile foundation has several piles; the several piles are used to support the foundation cap.

[0005] Furthermore, the pile foundation consists of four piles; the four piles, viewed from above, are arranged in a square matrix.

[0006] Furthermore, the top of the foundation platform is 250mm to 400mm lower than the bottom of the base plate.

[0007] Another objective of this invention is to provide a bottom structure that, when combined with a tower crane foundation, forms a stable structure.

[0008] A bottom structure includes a base plate, a base plate cushion layer, and a tower crane foundation at a post-cast strip location; the base plate cushion layer is disposed beneath the base plate; and the tower crane foundation is disposed beneath the base plate cushion layer.

[0009] Furthermore, the thickness of the base plate is greater than the thickness of the base plate pad layer.

[0010] Furthermore, the base plate is provided with a first post-pouring strip area; the first post-pouring strip area connects to the area above the foundation cap used for setting up a tower crane.

[0011] Furthermore, the first post-cast strip area is connected to the original first post-cast strip.

[0012] Furthermore, the first post-cast strip area is connected to the original second post-cast strip.

[0013] Furthermore, the first post-pouring strip area, the original first post-pouring strip, and the original second post-pouring strip are used for pouring backfill material after the project is completed.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model discloses a tower crane foundation at the post-cast strip location. The pile foundation is positioned below the base slab, and a foundation cap is placed on the pile foundation. The pile foundation supports the foundation cap, improving its stability. After installation, the foundation cap is located at the top of the post-cast strip in a top-down view, with its top lower than the bottom of the base slab.
