[0002] At present, there is a relatively mature construction technology for concrete surface construction. Combined with the structural characteristics of the project, a layer of steel mesh is arranged in the concrete of the container stack surface. The degree of control of the thickness of the steel mesh protective layer not only affects the appearance quality of the surface concrete (cracks), but also directly determines the durability and service life of the concrete, affects the construction quality, and reflects the production process and technical level of the construction unit.

[0003] Since the steel mesh bears the load from construction workers and concrete pouring during the surface layer pouring process, it is easy to cause the steel mesh to collapse in the middle and warp around, which increases the difficulty of controlling the thickness of the protective layer. Therefore, the steel mesh installation process processes the steel bars into stirrups according to the thickness of the structural layer and the thickness of the protective layer, arranges the stirrup spacing reasonably, controls the thickness of the surface protective layer, and ties the steel stirrups and the steel mesh as a whole. The installation process requires processing, installing, and tying steel stirrups. The process is relatively cumbersome, which not only increases the workload, but also consumes a large amount of stirrup steel bars, increasing costs. Utility Model Content

The surface of the threaded sleeve 31 is welded to the inner wall of the installation groove 2 . The hook 32 is installed on the inner wall of the threaded sleeve 31 .

[0024] The vertical support assembly 4 includes a hydraulic telescopic cylinder 41 and a base plate 42. The base plate 42 is connected to the bottom of the hydraulic telescopic cylinder 41. The telescopic end of the hydraulic telescopic cylinder 41 is connected to the surface of the beam 1. Before pouring concrete, the steel mesh 5 is laid in the area to be poured. The on-site operator will cross the beam 1 on both sides of the formwork 6. The elevation of the top of the steel mesh 5 adjustment device is adjusted. The construction personnel will lift the steel mesh 5 and close it with the hook 32 to limit it. Then, concrete pouring is carried out. Before the concrete begins to set, all the hooks 32 are twisted to disengage the steel mesh 5. The entire device is dismantled and the hook 32 is repaired. The beam 1 hangs the steel mesh 5 through the hook 32 to transmit the vertical load. The vertical support assembly 4 performs coarse adjustment on the elevation of the steel mesh 5, and the positioning assembly 3 performs fine adjustment on the elevation of the steel mesh 5. The hook 32 is close to the steel mesh 5 to limit it to ensure the elevation of the steel mesh 5. It is easy to use and reusable, saving cost.

[0026] Production of beam 1: Determine the length of beam 1 according to the width of the control surface concrete protective layer. The number and spacing of threaded sleeves 31 are determined according to the width of the poured concrete and the size of the steel mesh 5. Ensure that the hook 32 inside the threaded sleeve 31 is staggered with the longitudinal steel bars of the steel mesh 5. Beam 1 is made of galvanized square tube with an outer side length of 150mm×150mm and a thickness of 6mm in the cross section.
