Novel tower crane foundation structure combining steel beam bottom beam and wall tie

Abstract

The invention discloses a novel tower crane foundation structure combining a steel beam bottom beam and a wall tie. The novel tower crane foundation structure combining the steel beam bottom beam andthe wall tie comprises a steel beam bracket, a rotary table, a bearing seat, a rotating tower, a load-bearing arm frame, a hook, a steel beam base frame and a steel beam foundation. The steel beam base frame comprises a center piece, a connecting piece, a fixing piece and an end piece. The steel beam foundation comprises an outer frame, a skeleton, a fixing seat and a foundation embedded part. Thefoundation embedded part comprises a cross bar, a fixed bracket, an auxiliary bracket and a fixed rib plate. The bearing base rotates on the rotary table, the rotating tower rotates along with the bearing base, and the load-bearing arm frame rotates along with the rotating tower. The foundation embedded part is embedded underground and fixedly installed below the ground to complete the normal installation of a tower crane. The foundation which is originally affected by own gravity and the overturning moment of the whole machine tends to be only affected by the own gravity, so that dependenceon the bearing capacity of the foundation is reduced. The one-site structural environment is effectively used in the application of the steel beam foundation, the safety of the foundation is improved,construction costs are greatly saved, and the construction efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of tower crane foundation structures, in particular to a new type tower crane foundation structure combined with a steel beam bottom beam and an attached wall. Background technique [0002] With the development of society and economy, the application of tower cranes is becoming more and more common, especially the rising labor costs. In order to save costs and pursue construction progress and construction quality, tower cranes have become the first choice for various types of construction sites as auxiliary equipment for construction. . Whether it is a new construction site or a rebuilding of a building, tower cranes have become the first choice for vertical transportation. However, as a special equipment, the use of a tower crane has its particularity. When making a conventional foundation, any tower crane has higher requirements for the bearing capacity of the foundation where the foundation is located. If th...

Problems solved by technology

If the conventional method is used, in order to meet the requirements in the manual, a very large cost will inevitably be invested, and for some environments, there is no condition for building a large-scale natural foundation, such as installing a tower crane on the roof of the basement. The cost is dealt with by measures such as topping, which will also seriously affect the construction period and increase a series of unsafe factors
