Problems solved by technology

[0005] However, the distribution of the steel strands of the tower crane foundation of the cross-shaped concrete prefabricated assembly is too concentrated, resulting in excessive local stress, which is easy to cause damage to the prefabricated parts; the contact area between the foundation and the ground is small, and a relatively large foundation bearing capacity is required; shear resistance Concave and convex parts are easily damaged; bolts embedded in the foundation are easily damaged and need extra protection, and installation and removal of anchor bolts will cause labor waste

Abstract

The invention discloses a prefabricated and assembled tower crane foundation, which is formed by assembling concrete prefabricated parts, wherein the tower crane foundation comprises two groups of first prefabricated foundations which are parallel to each other in a transverse direction and two groups of second prefabricated foundations which are parallel to each other in a longitudinal direction; the two groups of first prefabricated foundations and the two groups of second prefabricated foundations are distributed in a grid-shaped manner, and are connected and locked through steel strands, the steel strands consist of two groups of first steel strands which are respectively arranged in the two groups of first prefabricated foundations and two groups of second steel strands which are respectively arranged in the two groups of second prefabricated foundations, and the two groups of first steel strands and the two groups of second steel strands are also distributed in a grid-shaped manner. The tower crane foundation can be recycled and has a larger contact area with the ground, and the steel strands are more uniformly distributed and dispersed in the foundation, so that the stress of the tower crane foundation is more uniform.

Description

technical field [0001] The invention relates to the technical field of tower cranes, in particular to a prefabricated and assembled tower crane foundation, which is used for connecting and fixing tower cranes. Background technique [0002] With the in-depth development of the construction industry, tower cranes (also referred to as "tower cranes") have been widely used. The promotion and use of tower cranes has gradually changed the vertical and horizontal transportation methods of construction, created safe working conditions for operators, and improved work efficiency. [0003] At present, the foundation of most tower cranes adopts the traditional block foundation. The traditional block foundation can only be poured on site. The foundation pit is dug first, then the outriggers or bolts and steel mesh are put into the foundation pit, and finally the concrete is poured to form a one-time construction. The integrated foundation for permanent use has a long production time, c...
