Problems solved by technology

According to the conventional method of processing and manufacturing reinforcement cages with walls, the upper and lower layers of horizontal reinforcement are Z-shaped. When making reinforcement cages, they need to be welded vertically to the ground platform. The operation is not easy, the process is complicated, time-consuming, and there are risks.

Embodiment 1

[0031] Embodiment 1: as Figure 1-5 As shown, the present embodiment relates to an overall processing method of a Z-shaped reinforcement cage for a ground connection wall, and the overall processing method includes the following steps:

[0032] Step (1): If figure 2 As shown, the lower L-shaped horizontal reinforcement 1 is laid, except for the upper part of the vertical section of the lower L-shaped horizontal reinforcement 1, the longitudinal reinforcement 6 is welded on the inner side of other positions of the lower L-shaped horizontal reinforcement 1 to form the first part of the lower longitudinal truss reinforcement . In addition, the outer side of the vertical section of the lower L-shaped horizontal rib 1 is provided with a first temporary support bracket 5 placed obliquely. One end of the first temporary support bracket 5 is fixed on the ground or the processing platform, and the other end is spot welded to the lower L-shaped horizontal rib 1. Fixed, used to suppor...

Embodiment 2

[0037] Embodiment 2: as Figure 5-7 Shown, a kind of hoisting method of the Z-shaped reinforcement cage of the ground connection wall, the hoisting method comprises the following steps:

[0038] 1. Use the main crane 11, auxiliary crane 12 and auxiliary crane 13 to hoist the Z-shaped reinforcement cage of the ground connection wall, and remove all temporary support brackets. Among them, there are 6 lifting points that can be connected with the main crane 11 on the Z-shaped reinforcement cage of the ground connection wall, which are respectively lifting point a, lifting point b, lifting point c, lifting point d, lifting point e and lifting point Point f, lifting point a and lifting point b are all set at the side of the lower longitudinal truss reinforcement of the Z-shaped reinforcement cage of the ground connection wall, and the lifting point a and lifting point b are respectively located at the lower and upper layers of the lower longitudinal truss reinforcement. Both c and...

Abstract

The invention discloses an integral machining method of a Z-shaped reinforcement cage of a diaphragm wall. The integral machining method comprises the following steps that lower-layer L-shaped horizontal bars are laid, and longitudinal reinforcements are welded to on the inner sides of the lower-layer L-shaped horizontal bars except the upper parts of vertical sections of the lower-layer L-shaped horizontal bars; upper-layer linear horizontal bars are welded on the vertical sections of the lower-layer L-shaped horizontal bars, and longitudinal reinforcements are welded on the inner sides of the upper-layer linear horizontal bars except one sides, close to the vertical sections of the lower-layer L-shaped horizontal bars, of the upper-layer linear horizontal bars; lower-layer linear horizontal bars are welded at the junction of the vertical sections of the lower-layer L-shaped horizontal bars where the longitudinal reinforcements are welded and the junction of the vertical sections of the lower-layer L-shaped horizontal bars where the longitudinal reinforcements are not welded, and longitudinal steel bars are welded on the inner sides of the lower-layer linear horizontal bars except the horizontal sections of the lower-layer L-shaped horizontal bars and the same sides of the upper-layer linear horizontal bars; and upper-layer L-shaped horizontal bars are welded, and longitudinal reinforcements are welded on the inner sides of the upper-layer linear horizontal bars except one sides, close to the horizontal sections of the lower-layer L-shaped horizontal bars, and the Z-shaped reinforcement cage of the diaphragm wall is obtained.

Description

technical field [0001] The invention relates to the technical field of ground-connected wall steel cages, in particular to an overall processing method for ground-connected wall Z-shaped steel cages. Background technique [0002] There are "one-shaped", "L-shaped" and "Z-shaped" reinforcement cages for the ground connection wall. Its structure is mainly divided into upper and lower layers of steel bars and connecting trusses between them. Ribs, welded and fixed→Welded trusses and reinforcements→Laying longitudinal reinforcements on the lower layer and welding them firmly→Welding bottom protection pads→Trusses and reinforcements were erected and fixed by welding→Welding upper longitudinal reinforcements→Welding upper horizontal reinforcements→Welding Ribs for the upper lifting point → welding additional ribs and protective pads. Among them, the "Z-shaped" ground connection wall is difficult to construct and requires high requirements. It is generally constructed in the way o...
