Description

Rectangular reinforcement cage welding equipment

Technical Field

The utility model belongs to the technical field of building construction, and particularly relates to rectangular reinforcement cage welding equipment.

Background

In the process of foundation engineering construction, a large-area foundation pit is often required to be excavated, if foundation pit excavation work is directly carried out on the ground, and the danger of landslide or collapse exists in soil at the periphery of the foundation pit, therefore, a common construction method is that a groove body enough for forming a diaphragm wall is excavated at the periphery of the foundation pit before pit excavation, then concrete is poured after a reinforcement cage is placed in the groove body, and the foundation pit excavation work can be started after the concrete pouring is finished. Most of the prior wall-connected reinforcement cages are rectangular cross sections with different sizes, and fig. 1 is a schematic diagram of the prior wall-connected reinforcement cage, and consists of an upper net sheet 01, a lower net sheet 02, a longitudinal truss girder 03 and sealing ribs 04; FIG. 2 is a schematic view of the upper web of FIG. 1, with upper web 01 indicating that transverse ribs 010 are disposed above longitudinal ribs; FIG. 3 is a schematic view of the lower mesh sheet of FIG. 1, the lower mesh sheet 02 indicating that the transverse ribs 010 are disposed below the longitudinal ribs; the longitudinal bars may be a single bar (single bar 011) or two side-by-side bars (parallel bars 012, one of which is smaller or equal in diameter).

In the welding process, the manual laying work of the net sheet occupies a lot of time, the laying length of the platform is related to the actual length of the reinforcement cage, the longer the reinforcement cage is, the longer the reinforcement laying platform needs to be laid, and in order to ensure the laying precision of the reinforcement, the time and labor are wasted in the installation and leveling work of the platform; wherein, in the process of arranging the reinforcing steel bars, all transverse reinforcing steel bars and longitudinal reinforcing steel bars need to be manually lifted and placed on a reinforcing steel bar arranging platform, and for long longitudinal reinforcing steel bars, the combined force of multiple people is required to be synchronously lifted and placed, and the process belongs to repeated labor with heavy physical force and has higher risk; the spot welding workload of the upper net sheet 01 and the lower net sheet 02 is larger, the manual welding quality is not well controlled, a large amount of repeated labor is needed, and the human body consumption is large; finally, the longitudinal truss girder is welded manually, which is time-consuming and labor-consuming. When the existing movable welding equipment is used for welding the reinforcement cage meshes, the manual welding of the upper mesh 01 and the lower mesh 02 can be replaced, but because the track installation of the single welding equipment is required to be the same as the length of the reinforcement cage, the occupied space is large, the accuracy required for the track installation is high, the welding preparation period is long, and the component debugging is complex; in addition, the problems of automatic laying of the reinforcing mesh and effective welding of the longitudinal truss girder 03 cannot be solved, and the problems of high labor cost and low welding efficiency exist.
