[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0022] As shown in the figure, the utility model describes a high-precision combined building of a steel-wood structure, wherein the main body is a steel structure, the outer wall 2 and the roof 5 are wooden structures, the steel structure is composed of a steel column 3 and a steel beam 4, the steel column 3 is a cross steel column, the steel column includes a middle cross support 8 and a base plate 9 at the end of the cross support, the base plate 9 is vertically arranged to the cross support, the width of the base plate 9 is smaller than the width of the cross support 8, and the steel beam 4 is an H-shaped steel.

[0023] Steel structure installation process:

[0024] Pre-embed anchor bolts 11 - pour concrete - hoist steel column 3 - install steel beam 4 - weld steel beam and column nodes - install floor slab - rivet welding, steel bar tying, water and electricity pipeline installation - acceptance - install roof 5.

[0025] The utility model adopts TEKLA steel structure deepening software for layout, and at the same time performs mold matching with wood structure deepening software, compares each other, solves collision problems and other problems, and ensures accuracy.

[0026] According to the plan layout of the anchor bolts 11, the anchor bolts and flanges are assembled in categories. After the anchor bolts are installed, the concrete pouring work is carried out. When the steel column is hoisted, the crane hook adjusts the distance and angle so that the center line of the column body is aligned with the foundation axis, and the screw hole is aligned with the anchor bolt, and then the steel column is slowly dropped so that the anchor bolt can freely penetrate into the column foot bolt hole. There is a column foot 10 under the steel column. Figure 3 As shown, anchor bolts 11 are provided on the column base, beam reinforcements 12 are provided on the base plate and the cross support member below the steel column, and stiffening ribs 13 are also provided on the surface of the base plate, so as to form a stable rigid frame system.
