Problems solved by technology

Due to the poor welding conditions at the construction site, the space of many welding places is narrow and the requirements for welders are high when working at heights, the reinforcement surfaces of the lattice columns are often not on the same plane, and it is necessary to install triangular steel plates between the angle steel and the lattice columns for reinforcement. , so the reliability of the welded connection is often not guaranteed; in addition, after the lattice column is dug out, the stability of the tower crane foundation is reduced, and the tower crane is not allowed to be used. It often takes 3-5 days of continuous work to do a reinforcement, and many The construction unit used the tower crane as usual before the diagonal braces were reinforced, posing a major safety hazard

Embodiment Construction

[0033] Further description will be given below in conjunction with the embodiments shown in the accompanying drawings.

[0034] like figure 1 , figure 2 The shown new tower crane foundation lattice column reinforcement device includes a column holding assembly 1 , a support rod 2 and a ball connection assembly 3 .

[0035] like Figure 1 to Figure 3 As shown, the column holding assembly is detachably installed on the outer periphery of the lattice column 4; the column holding assembly includes a splint 1-1 and a holding hoop 1-2. The splint adopts a steel plate bent at a right angle, wherein two adjacent bending surfaces on the splint are respectively the first bending surface 1-2-1 and the second bending surface 1-2-2. The hoop is fixed on the plywood and cooperates with the plywood to fasten the lattice column. Specifically, the two outer planes of the splint are respectively provided with bumps 1-3, and the bumps are provided with a first U-shaped groove 1-3-1; the siz...

Abstract

The invention belongs to the technical field of building hoisting machinery foundation reinforcement. The invention aims to provide a novel tower crane foundation latticed column reinforcing device which has the characteristics of convenience in installation and firmness in connection. According to the technical scheme, the novel tower crane foundation latticed column reinforcing device is characterized by comprising column embracing assemblies detachably installed on the periphery of a latticed column and supporting rods for connecting the column embracing assemblies in pairs; the column embracing assembly comprises a clamping plate which is bent in a right-angle mode and a hoop which is fixed to the clamping plate and matched with the clamping plate to hoop the latticed column. And ball connecting assemblies connected with the supporting rods are arranged on the first bending surfaces and the second bending surfaces which are adjacent on the clamping plates.

Description

technical field [0001] The invention belongs to the technical field of foundation reinforcement of construction hoisting machinery, and in particular relates to a tower crane foundation lattice column diagonal bracing reinforcement device. Background technique [0002] With the development of society, the demand for underground space in urban buildings is increasing. The original one-story basement can no longer meet the demand. The basement of modern urban buildings is generally more than two floors. Four lattice columns are often used as support under the tower crane foundation cap of such construction sites. With the excavation of the foundation, the four lattice columns need to be reinforced with diagonal bracing. The existing reinforcement measures are mainly to measure the size on site and use the corresponding cross-sectional area. The angle steel is welded and strengthened between the lattice columns. Due to the poor welding conditions on the construction site, the ...
