Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing:

[0012] In the figure, 1. concrete base; 2. horizontal support; 3. cross support;

[0013] Such as figure 1 As shown, four steel lattice columns are fixed on the concrete base 1, and the distance between the steel lattice columns is 3 meters. There are horizontal support 2 and cross support 3 between the steel lattice columns. The cross support 3 is a telescopic structure, consisting of two sections Steel rods and round tubes connected to the steel rods in front of the steel bars. Each steel grid column is composed of five column tubes 4 with a length of 2.5 meters and a cross-section of . The upper part of the pipe 4 extends into the tower crane base, the lower part of the column tube 4 at the bottom extends into the concrete base 1, the lower part of the column tube 4 at the bottom is provided with a grout hole 5, and the concrete base 1 is provided with Reinforcement ca...

Abstract

The invention provides a demountable tower crane foundation which comprises steel grid columns and concrete bases, wherein the two steel grid columns are fixed on the concrete bases, horizontal braces and X-braces are arranged between the steel grid columns, the demountable tower crane foundation is characterized in that each steel grid column comprises 3 to 8 column component round tubes which are sequentially connected, the lower parts of the column component round tubes at the bottoms of thesteel grid columns extend into the concrete bases, and grout leakage holes are formed in the lower parts of the column component round tubes at the bottoms of the steel grid columns. Each steel grid column is formed by splicing a plurality of the column component round tubes, and all column component round tubes, except the column component round tube at the top of each steel grid column and the column component round tube at the bottom of each steel grid column, can be recycled, so that the reutilization rate of the steel grid columns can reach 75 percent, and the reutilization rate of the steel grid columns is increased remarkably compared with that of steel grid columns in other tower crane foundations; adjacent column component round tubes are connected through small round tubes, bolts and nuts, and the assembling and the dismantling are convenient. The horizontal braces and the X-braces are connected with the column component round tubes through supporting connection plates, the horizontal braces and the X-braces adopt demountable structures and can be all recycled, and the dismantling by workers is convenient.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular to a detachable tower crane foundation. Background technique [0002] Fixed tower cranes are widely used in modern industrial and civil buildings, and are mainly used to solve the problem of vertical transportation in building construction. In order to ensure the normal and safe operation of the tower crane, the tower crane must be fixed on the tower crane foundation, so the tower crane foundation must have sufficient strength, overturning resistance and shear resistance, and the tower crane foundation must not damage the foundation structure of the building facilities. However, the existing tower crane foundation has a high amount of concrete, a large amount of reinforcement, a long construction period from construction to investment, low safety, and cannot be reused. After the construction is completed, it will become engineering waste or affect outdoor water supply and drain...
