The manufacturing and construction process comprises the following steps:
manufacturing rib lattice structures of the first wall body and the second wall body according to the design result, binding the construction steel bars, and putting the building blocks to preset positions; then, a first connecting piece and a second connecting piece are processed and manufactured, the first connecting piece is installed at the preset position of the side rib column of the first wall body, and the second connecting piece is installed at the preset position of the side rib column of the second wall body; and then, pouring wall concrete and curing.
Wherein, in the first connecting piece or the second connecting piece, channel steel is welded and fixed well as a stiffening piece; and in the channel steel welding process, the opening direction of the channel steel is simultaneously arranged clockwise or anticlockwise, so that the anchoring with post-cast column concrete is facilitated.
after the wall body is maintained, the wall body is transported to the site for hoisting;
before hoisting, a slurry layer with the thickness of 10mm is laid at the position corresponding to the lower end of the wall body so as to ensure that the wall body is in close contact with a floor slab or a foundation surface;
after the wall body is hoisted in place as required, the first connecting piece and the second connecting piece are fastened together by utilizing a screw rod and a disk-shaped nut, and the hollow column body structure is formed at the vertical seam of the wall body; then, post-cast column concrete is constructed in the hollow column structure, after the strength of the post-cast column concrete reaches the design strength, the disc-shaped nut is removed, and the screw rod is pulled out; and finishing the construction of the wall connecting piece.
The wall connecting structure provided by the embodiment replaces a template of the connecting structure of the longitudinal and transverse walls of the traditional assembled type section steel composite wall by arranging the H-shaped steel column and the connecting plate, so that the construction quality is improved, the construction speed is greatly improved, and the labor cost is reduced; the channel steel is arranged in the hollow column body structure and is used as a stiffening piece, and the channel steel replaces a reinforcing cage of the connecting column to be used as a reinforcing cage in the connecting column, so that adverse effects caused by binding and hoisting of the reinforcing cage are avoided, the construction efficiency is improved, and the bearing capacity of the longitudinal and transverse wall connecting structure is improved; the long round holes are formed in the web plate of the H-shaped steel column and the web plate of the channel steel, so that the concrete pouring quality during wallboard prefabrication is guaranteed, the bonding strength of the section steel and the concrete is improved to a certain extent, and the bearing capacity of the wall body and the connecting column is improved.
In the embodiment, in the processing and manufacturing process of the wall connecting piece, welding is adopted between the H-shaped steel column and the connecting plate, and between the connecting plate and the channel steel; in the welding and fixing process of the H-shaped steel column and the connecting plate and the channel steel and the connecting plate, deformation caused by high welding temperature is avoided; the H-shaped steel column is connected with the connecting plate in a welding mode through a groove welding seam; the channel steel is connected with the connecting plate by welding seams; the butterfly nuts and the screws are only used for fixing the wall body when post-cast column body concrete is poured, and the butterfly nuts and the screws need to be dismantled after the strength is achieved; mounting seams are reserved at the end parts of the wall body to ensure that field hoisting is smoothly carried out; the weak surface of the connecting plate between the adjacent walls can be reinforced by spot welding.
In the utility model, the wall body connecting structure is arranged at the vertical seam of the wall bodies of the adjacent wall bodies, namely, the connecting column of the wall bodies and the wall bodies adopts H-shaped steel and the connecting plate thereof to replace a template of a traditional connecting column; meanwhile, channel steel is used for replacing a reinforcement cage of the connecting column, so that the supporting of a formwork and the hoisting of the reinforcement cage for the connecting column in a construction site are avoided; the synergistic effect of steel and concrete fully utilizes the advantages of two materials, has the characteristics of high strength, high rigidity, convenient construction and the like, has better construction efficiency and bearing capacity than the traditional longitudinal and transverse wall connecting structure of the multi-ribbed composite wall, and has great economic benefit.
