[0008] The support truss is composed of a left wing, a right wing and web members, wherein the left wing and the right wing are angle steel or channel steel structures, and a plurality of web members are arranged between the left wing and the right wing at corresponding positions.

[0009] The web members are connected head to tail in a Z-shaped structure, and the two ends of the web members are welded or anchored to the corresponding left wing or right wing.

[0010] The inner and outer removable form boards are cement fiber boards, calcium silicate boards or gypsum boards.

[0011] The end and middle positions of the bottom beam, top beam and corner column are respectively provided with inwardly bent embedded parts.

[0012] The outer surfaces of the outer removable form board and the roof are provided with a waterproof layer.

[0013] The prefabricated thermal insulation and decoration integrated unit house of the present application adopts the above structure and has the following advantages:

[0014] 1. The frame structure composed of the bottom beam, top beam and corner column can be designed in different sizes according to actual needs to meet different site requirements.

[0015] 2. The wall cavity between the inner and outer removable form boards is poured with polystyrene particle thermal insulation grouting material to form a wall panel, which not only has thermal insulation performance but also quickly forms a unit house.

[0016] 3. The support truss is arranged in the wall cavity and connected with the top beam and bottom beam upward and downward to ensure the overall strength of the wall.

[0017] 4. The support truss adopts a two-side angle steel or channel steel structure to effectively support the inner and outer removable form boards, and the web members on the inner side are in a Z-shaped structure to further improve the overall strength of the wall.

[0018] 5. The wall cavity encloses the bottom beam, top beam and corner column, and the roof is connected with the top beam and corner column around, thereby realizing an integrated structure after pouring to block the heat transfer effect.

[0019] 6. The outer surfaces of the outer removable form board and the roof are provided with a waterproof layer to improve the waterproof performance of the unit house. BRIEF DESCRIPTION OF DRAWINGS
