Embedded tower crane foundation and construction mode thereof

Abstract

The invention relates to an embedded tower crane foundation and a construction mode thereof. The embedded tower crane foundation comprises a cubic fixed formwork used for pouring concrete. A plurality of wooden joints, steel pipes and split bolts are sequentially arranged on the outer sides of the four walls of the fixed formwork. The wooden joints are evenly arranged around the fixed formwork, and each wooden joint is arranged in the vertical direction of the fixed formwork. The steel pipes are arranged in the horizontal direction and the vertical direction of the fixed formwork. Two parallel steel pipes located on the two sides of the fixed formwork are fixedly connected through the split bolts. The bottom elevation of a basement base plate is flush with the bottom elevation of the tower crane foundation poured by the fixed formwork. A plurality of steel bars arranged in the horizontal direction are further arranged in the fixed formwork, and the steel bars are fixedly connected with structural steel bars of a base plate foundation. According to the embedded tower crane foundation and the construction mode thereof, the tower crane foundation is embedded in the basement base plate, so that a unified whole is formed; and the foundation engineering measure requirement and the functionality requirement are met. Meanwhile, concrete and steel bars are reduced, and the construction period is shortened.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an embedded tower crane foundation suitable for a basement and a construction method thereof. Background technique [0002] In recent years, with the prosperity and development of the construction industry, some large-scale office and commercial complexes with comprehensive functions have been widely constructed. Their own characteristics and economic benefit requirements make them mostly located in the environment of small construction sites and difficult construction; at the same time, The construction of large-scale complexes is often accompanied by the construction of large-volume foundation slabs, complex structural forms, and large amount of construction measures. [0003] The traditional tower crane foundation construction method is to set the tower crane foundation below the basement foundation floor, or the top surface of the tower crane foundation is consistent w...

AI Technical Summary

Problems solved by technology

[0004] First, if the tower crane foundation is set below the basement foundation floor, the foundation section of the tower crane needs to pass through the raft foundation and waterproof layer, which will inevitably affect the waterproof effect of the foundation; construction joints will be generated when the foundation section of the tower crane passes through the raft foundation, and cracks are easy to occur. Expansion will affect the construction safety; the foundation joints of the tower crane need to be waterproofed, and the waterproof steel plate is welded and the flexible waterproof material is paved. Moreover, after the tower crane is dismantled, the reinforcement materials in the foundation are not easy to recycle, resulting in waste of cost and materials

[0005] Second, if the top surface of the tower crane foundation is at the same elevation as the top surface of the raft foundation, the stress on the raft is not clear, which will affect the construction progress; and the surrounding area of ​​the tower crane foundation needs to be treated with water stop and steel bar joints; the raft foundation should be done first For the tower crane foundation of the following parts, for example, if the thickness of the raft is less than the height of the tower crane foundation, the tower crane foundation will be poured twice, and there will be horizontal construction joints during construction, which will affect the overall functionality of the tower crane; recycling, waste of resources
