The existing common light steel house wall construction technology at home and abroad has the following modes: (1) The whole factory is prefabricated into a film shell, and rock wool or polyurethane and glass fiber are adopted for filling on site, so that the hollow feeling of the house is obvious. (2) The method of prefabricating the whole wall is adopted in factories, and the problem is that the construction quality is influenced due to the fact that the decoration base layer is very complicated in treatment work because the embedded connecting boxes or the connecting steel sheets are required to be connected on site. (3) The mode of whole grout after the whole fossil fragments in scene are built, although solved the connection problem, the membrane problem that expands also appears easily, and the building site is dirty poor, and grout work is easily influenced by weather simultaneously, and the scene time limit for a project is longer relatively. (4) The factory prefabrication adopts a flat forging method for prefabrication molding, and has the problems of large occupied space of a die table, large equipment investment and low factory utilization rate; the mode of setting up the mould in groups is adopted, and the problems of inconvenient pre-buried reservation, large equipment mould investment and the like exist.

The production process essentially comprises the steps of adopting a flat forging method to operate a cavity mould shell consisting of a light steel framework, a panel and a pre-buried reserved part, then standing up to lean against the cavity mould shell in groups, and vertically pouring light concrete. Combines the advantages of high plane precision of the flat-forging method, convenient pre-burying and reservation and small space occupation of the vertical-forging method. And because the self-carrying panel is used as a disassembly-free template, excessive equipment mold investment does not exist, and the problem of mold expansion is solved.

Compared with the existing process, the cost can be obviously reduced. The method comprises the following steps:

1. Assembling the cavity mould shell by a flat forging method: as shown in fig. 12, on the horizontal workbench, the membrane shell assembly is completed through 10 steps of assembling (1) the keels, nailing (2) the keels, turning (4), nailing (5) the keels on the other side, then paving (6) the plates 10, nailing (7), turning (8), then paving the plates 9 and 16 (9), nailing and fixing (10), and stacking. The brackets indicate the steps.

2. And pouring light concrete by a group construction method: (1) The assembled cavity mould forms are put into a frame device in a group, wherein the first square pipe 31 and the second square pipe 32 are slidable fastening devices, so that the film shells are tightly attached; (2) And taking the group as a unit, integrally pouring concrete, integrally vibrating and integrally curing and forming. Because the adjacent wallboards are tightly squeezed, the mould expansion control measures of each wallboard are not needed. Because the veneer on two sides is a disassembling-free template, no extra mold is needed. As shown in fig. 13.

3. And (3) additionally laying an insulation layer, a waterproof layer and a finish coat on the basis of the formed inner wall board according to the construction requirement. The inner and outer wallboards of the structural part are completely consistent, and the standardization degree is improved. The prefabricated light steel composite wallboard house system and the assembly method are innovated as follows: (1) The method ensures that most of the wall is prefabricated in a factory, the quality is controllable, the compactness of the wall is good, and no empty feeling exists; (2) The flexibility of on-site installation is guaranteed by a small number of hollowed-out parts, meanwhile, the finished surface of the wall surface is complete, and the influence on decoration is small. The method has the advantages of convenience in connection of field assembly and controllable quality of factory prefabrication (3) and adopts a flat-beating forming cavity shuttering and a group mould-free vertical pouring process, so that pre-burying reservation and precision control are facilitated, pouring can be completed on the wall body only by supporting two wall bodies at the end parts, templates and expansion-resistant mould supports of each wall body are omitted, and cost and space are saved. (4) In addition, the integrated composite method of the decoration heat-preservation waterproof composite wall only needs to finish the splicing of the waterproof coiled materials on site, and then the facing is partially finished, so that the workload is small, a scaffold is avoided, the site construction cost is reduced, the wall is quickly sealed, a good protection effect is achieved for the inside of a house, and the quality and the durability of the house are improved. (5) The lap joint method of the coiled material at the splicing position of the wall body is a special structure which appears after the process of the wall body, and is simple and practical. (6) The traditional assembly decoration needs leveling keel leveling, mainly uses for pre-buried pipelines and leveling, occupies more space and has a hollowing feeling. In the system pipeline preset wall, the flatness of the wall surface is guaranteed through high-standard production and installation, and the leveling-free installation of the assembly type decoration plate can be guaranteed to be spliced and fixed on a wall module through the buckle metal lines. The method has the advantages of thin wall body total thickness and high yield. The key is that the wall body is thick and heavy without hollowness. And simultaneously, the decoration cost is reduced. (7) The integrated outer decoration is realized by factory prefabrication, and only the decoration surface at the spliced part of the wall body is required to be treated, so that the whole construction of the outer wall is converted into linear operation, a scaffold is omitted, and the cost is reduced.
