[0026] The utility model is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Example 1

[0028] This embodiment is explained by taking the common seven-purlin large wooden frame antique building as an example. The seven-purlin large wooden frame antique building has a thick roof surface layer, and is covered with tiles, which has a large load and a large number of anchor bolts (nails) connecting parts on the top and bottom; at the same time, the roof facade is usually multi-slope or even curved, and it is difficult to accurately arrange the template on site. Based on this, the roof adopts a steel truss floor deck. The requirements for materials, appearance, mechanical properties, etc. are detailed in the standard JG / T368-2012. In this embodiment, the steel truss floor deck model HB1-90 is selected.

[0029] like Figure 2 and Figure 3 As shown, this embodiment includes: a first transverse steel structure column 100, a vertical steel structure column 300 and a transverse connecting member 400;

[0030] The vertical steel structure column 300 is made of steel pipe; the surface of the vertical steel structure column is provided with a fireproof coating and a clear varnish wood surface layer in sequence;

[0031] The first transverse steel structural column 100 and the transverse connecting member 400 are made of steel, preferably hot-rolled H-shaped steel;

[0032] One end of the transverse connecting member 400 is connected to the first transverse steel structure column 100 by means of bolts 700 , and the other end is welded to the vertical steel structure column 300 by means of groove welding.

[0033] like Figure 1 In the seven-purlin large wooden frame antique building shown, a second transverse steel structure column 200 is also provided as the seven purlins, and the surface of the second transverse steel structure column is sequentially provided with a fireproof coating and a clear varnish wood surface layer; the so-called seven purlins include two eaves purlins, two lower golden purlins, two upper golden purlins and a ridge purlin in the middle, which are sequentially arranged from the outside to the inside, and a steel truss floor deck 600 is set on the upper end of the purlin. The lower end of the purlin is welded to the top of the vertical steel structure column 300, and the welding method is full penetration intersecting welding.

[0034] The purlin is connected to the steel truss floor deck 600 by shear bolts. In order to ensure the reliability of the structure while not destroying the architectural feature of the close fit between the purlin and the roof, hot-rolled equilateral angle steel is added to the inner side of the eaves purlin, and hot-rolled equilateral angle steel is added to both sides of the lower golden purlin, upper golden purlin and ridge purlin to strengthen the purlin. The hot-rolled equilateral angle steel is used to increase the contact area between the purlin and the roof, thereby improving the connection reliability.

[0035] The first transverse steel structural column 100 and the transverse connecting member 400 are covered with decorative wood layers to form a rectangular cross-section, reflecting the structural characteristics of the middle beam of ancient buildings.

[0036] In the seven-purlin large wooden frame antique building, minor or decorative components such as the ridgeline, moon beam, rafters, and connecting frames can still be made of wooden structures, so as to reflect the characteristics of the ancient buildings to the greatest extent.

[0037] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
