Embodiment

[0051] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the present invention is mainly realized through four steps, that is, installing the embedded plate, fixing the support, removing the tower crane foundation at the lower end of the support, and detecting the tower crane. Before implementing the construction method of the present invention, the tower crane should also be detected, which is the same as the detection after implementing the construction method of the present invention. The detection of tower crane includes the detection of the verticality of the tower crane, the measurement of the lightning protection grounding resistance of the tower crane, and the routine detection of the tower crane. For the detection of the verticality of the tower crane, the verticality of the free end part of the tower body 1 above the attachment is not greater than 4 / 1000, and the verticality of the tower body 1 below the attachment is not greater than 2 / 1000. The li...

Abstract

The invention discloses a construction method for tower crane foundation conversion, which comprises the following steps of: 1, arranging an embedded plate on a concrete structural column; 2, arranging a support in interference fit with a tower body on the tower body of a tower crane, and connecting the support on the embedded plate; 3, detaching a tower crane foundation at the lower end of the support; and 4, detecting the verticality of the tower crane, wherein the verticality of the free end part of the tower body above the attachment is not more than four thousandths, and the verticality of the tower body below the attachment is not more than two thousandths. By adopting the construction method, the support is first fixed on the tower body 1 of the tower crane, the support supports the load of the tower crane, and then the tower crane foundation is detached, so the tower crane continuously provides construction for a main building can be ensured under the supporting effect of the support and an annex building can also be put into use in advance.

Description

technical field [0001] The invention relates to a tower crane, in particular to a construction method for foundation conversion of the tower crane. Background technique [0002] Tower cranes, as lifting equipment in building construction, mainly provide vertical transportation for construction. Many building constructions involve tower cranes passing through the podium, which saves floor space during the construction process, but the podium can only be put into use after the main building is completed, which prevents effective use of resources. Contents of the invention [0003] The purpose of the present invention is to provide a construction method for tower crane foundation conversion. [0004] The purpose of the present invention is mainly achieved through the following technical solutions: the construction method of tower crane foundation conversion may further comprise the steps: [0005] Step 1. Install the embedded slab on the concrete structural column;...
