[0003] Light steel keel composite wall is a new type of building material with light weight, high strength, adaptability to waterproof, shockproof, dustproof, sound insulation, sound absorption, constant temperature and other functions. It also has the advantages of short construction period and simple construction. It is generally made of high-quality continuous hot-dip galvanized sheet as raw material and rolled by cold bending process. It is used in ice coffins, terminal buildings, passenger stations, stations, theaters, shopping malls, factories, office buildings, old building renovation, interior decoration and other places; the cross-sectional shape of the keel currently used is "C" shape. By arranging a composite sandwich panel on the outside of the light steel keel frame, the composite wall has the properties of waterproof and fireproof, but the manufacturing process of the composite sandwich panel is relatively complicated and the production cost is high. At the same time, after the composite sandwich panel is set, the exterior wall decoration layer cannot be set, which affects the beauty of the composite wall.

[0004] In view of the above situation, it is necessary to improve the existing wall structure so that it can adapt to the current needs for wall installation structure and its aesthetic decoration. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the cross-sectional shape of the currently used keel is "C"-shaped, and by arranging a composite sandwich panel on the outside of the light steel keel frame, the composite wall has waterproof and fireproof properties, but the manufacturing process of the composite sandwich panel is relatively complicated and the production cost is high. It is impossible to set an exterior wall decorative layer, which affects the appearance of the composite wall. Therefore, we designed a composite wall with a changed keel structure and an improved wall structure.

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is a light steel keel composite wall, comprising a light steel keel frame, a one-time formed composite wall made by pouring concrete with the light steel keel frame as a template and assisting BY grouting material; wherein, a calcium silicate board is provided on the light steel keel frame, a decorative layer is provided on the outer side of the calcium silicate board, and thermal insulation mortar is provided between the calcium silicate board and the decorative layer; the light steel keel frame comprises a light steel keel and a plurality of expansion bolts, the light steel keel comprises a corner keel, a connecting keel which is perpendicular to the corner keel, and an S-shaped keel arranged on the supporting member; the corner keel and the connecting keel are fixed to the beams and slabs of the building structure by expansion bolts, the connecting keel is clamped with the corner keel, and the S-shaped keel is connected with the connecting keel.

[0007] As a further supplement to this solution, the corner keel is T-shaped, the connecting keel is T-shaped, the corner keel and the connecting keel are clamped and fixed by screws or rivets, and one side of the S-shaped keel is a plane and the other side is a curved surface, i.e., S-shaped.

[0008] As a further supplement to the present solution, the S-shaped keel is provided with a plurality of through holes for facilitating the passage of steel bars so as to be used for fixing the steel bars.

[0009] As a further supplement to this solution, a mineral wool board is installed on the side of the light steel keel frame close to the wall top, and the mineral wool board is arranged between the light steel keel frame and the calcium silicate board.

[0010] To further elaborate on this solution, the corner keels are installed vertically, and the connecting keels are installed vertically to the corner keels.

[0011] To further elaborate on this solution, the connecting keels are arranged along the length of the wall, and the number of connecting keels is more than 2.

[0012] To further explain this solution, the number of S-shaped keels provided is 3 or more.

[0013] A process for implementing a light steel keel composite wall comprises the following steps:

[0014] 1) According to the architectural design drawing, the center line and edge line of the partition wall are popped up on the indoor floor, and then measured to the two main structural walls or columns and the bottom surface of the floor slab, and the door and window opening lines are popped up at the same time;

[0015] 2) Install the corner keels and fix them with nails or drill holes and connect and fix them with expansion bolts;

[0019] 6) Install the wall panel on one side of the light steel keel frame. The panel size is determined according to the actual use area. Use self-tapping screws to fix the panel on the light steel keel frame. The self-tapping screw heads are slightly embedded in the panel, but the face paper of the panel must not be damaged;

[0020] 7) Pour concrete according to the external shape of the light steel keel frame, clean the gaps in the composite wall, remove debris from the seams, fill with putty, and when the putty is initially set (about 30-40 minutes), scrape a thinner layer of putty with a thickness of 1mm, then stick a perforated paper tape. After the paper tape is pasted, leave it for a while. After the moisture evaporates, scrape another layer of putty on the paper tape, press the paper tape, and level the joint board at the same time.

[0021] To further elaborate on this solution, the putty adopts flexible anti-cracking and waterproof putty for interior walls.

[0022] Its beneficial effects are that it adopts concrete pouring and assists BY grouting material, which is a new type of green and environmentally friendly building material, which is convenient for people to use in daily situations, and BY grouting material has excellent structural performance, low cost and convenient use; the S-shaped keel is adopted, which can well position the steel bars to prevent them from shaking during concrete pouring, thereby affecting the strength and facilitating construction; the thermal insulation mortar is adopted, which can effectively insulate the room; and a decorative layer is provided, which is convenient for people to decorate according to their preferences; the light steel keel frame is covered with calcium silicate board, which can play an excellent fireproof and moisture-resistant role.
