The arc section 3 is designed according to the slope of the roof. At this time, it is only necessary to set a secondary structure on the straight section to form a ridge shape and smoothly connect it with the arc section 3, so as to realize the slope design of the roof, which not only reduces the use of materials, but also reduces the additional pressure on the truss, thereby reducing the construction difficulty and construction cost.

[0033] like Figure 1 , Figure 2 As shown, in the truss structure provided by the present embodiment, the ends of the two arc segments 3 are respectively provided with first connecting columns 6, and the first connecting columns 6 are used to connect with the concrete column 14.

The two arc segments 3 are installed on the concrete column 14 through the connecting columns to complete the installation of the entire truss structure, and are connected through the ends of the arc segments 3. The hollow part in the middle is larger, and the space available for construction is larger.

[0034] like Figure 1 , Figure 2 As shown, in the truss structure provided in this embodiment, a side of the first connecting column 6 away from the arc section 3 is provided with an outwardly extending eaves beam 7, the eaves beam 7 is a variable cross-section inclined beam, and its top surface is inclined downward, and the eaves beam 7 can guide rainwater on the roof, making the discharge of rainwater more convenient and better protecting the wall of the building.

Since the bottom wall of the inclined section 11 is inclined, the direction of the diagonal rod 13 changes at this time, and the diagonal rod 13 is vertical to the inclined section 11, which is more convenient for installation. The direction of the diagonal rod 13 of the third straight section 10 is the same as the direction of the diagonal rod 13 of the inclined section 11, so that the distribution of the diagonal rod 13 looks more regular and more aesthetically pleasing.

[0039] In addition, if Figure 1As shown, this embodiment also provides an antique roof, including: concrete columns 14 and the above-mentioned truss structure, the concrete columns 14 are multiple and spaced apart, the upper chord 1 in the truss structure is installed on the multiple concrete columns 14, in this embodiment, the first connecting column 6 and the second connecting column 8 on the upper chord 1 are installed on the concrete column 14.
