[0029] The cantilevered oblique wooden beam 1 is arranged symmetrically about the central axis. The lower end of the cantilevered oblique wooden beam 1 is connected to the wooden frame through the lower node metal connector 8, and the upper end is inclined and installed with the upper node metal connector 9. Figure 1 , Figure 2 and Figure 4 ;
[0030] The metal cables 2 correspond to the cantilevered oblique wooden beams 1 one by one. One end of the metal cables 2 is connected to the upper node metal connector 9 on the corresponding cantilevered oblique wooden beam 1, and the other end is connected to the metal ring 3. The metal ring 3 is horizontal and located on the central axis. All metal cables 2 are on the same horizontal plane and are symmetrically arranged on the metal ring 3. Figure 1 and Figure 2 ;
[0031] The secondary wood beams 4 are installed horizontally between adjacent cantilevered diagonal wood beams 1 and arranged in multiple rows. Figure 1 .
[0032] From the above scheme, it can be seen that the present application provides a stable wooden structure with a large span and long cantilever, which combines the compressive resistance of the wooden structure and the tensile resistance of the cable, so that the cantilevered inclined wooden beam 1 is compressed and the metal cable 2 is tensile, thereby forming a stable force system, which can be derived into a variety of architectural configurations and has good application prospects in low-rise wooden structure buildings.
[0033] like Figure 1 , Figure 2 and Figure 3 As shown, in the present embodiment, preferably: at the upper end node of the cantilevered oblique wooden beam 1, the cantilevered oblique wooden beam 1 and the secondary wooden beams 4 on both sides are provided with mounting grooves and the sides of the mounting grooves are provided with bolt holes, the upper node metal connector 9 is provided with bolt holes and cable holes, the upper node metal connector 9 is simultaneously inserted into each mounting groove at the node and locked by a through bolt 10, and one end of the metal cable 2 is connected to the cable hole.

[0035] like Figure 1 As shown, in this embodiment, the number of the cantilevered oblique wooden beams 1 is 4. Of course, the number can also be greater than 4, and the specific number is set according to actual needs.
[0036] In this embodiment, the metal cable 2, the metal ring 3, the lower node metal connector 8 and the upper node metal connector 9 are made of steel.
[0037] The construction steps of the above-mentioned cable-wood combined cable net structure are:
[0038] Before construction: In the factory or on site, installation grooves are opened at the top of the columns 6 and beams 7 of the wooden frame, at both ends of the cantilevered diagonal wooden beam 1, and at both ends of the uppermost secondary wooden beam 4, and bolt holes are drilled on the sides of the installation grooves;
[0039] During construction: first install the lower end node of the cantilevered inclined wooden beam 1, and the lower node metal connector 8 is inserted into each installation groove at the node and locked by the through bolt 10, so that each cantilevered inclined wooden beam 1 is initially fixed on the wooden frame; then the upper node metal connector 9 is inserted into the installation groove at the upper end of the cantilevered inclined wooden beam 1 and locked by the through bolt 10, and then one end of the metal cable 2 is connected to the cable hole and the other end is connected to the metal ring 3. After all the metal cables 2 are connected, adjust the length of the metal cable 2 so that the metal ring 3 is horizontal and located on the central axis, all the metal cables 2 are on the same horizontal plane and are symmetrically arranged on the metal ring 3, so that the cantilevered inclined wooden beam 1 is more stable; then the secondary wooden beam 4 is horizontally installed between adjacent cantilevered inclined wooden beams 1 and arranged in multiple rows. For the uppermost secondary wooden beam 4, the installation groove at its end is matched on the upper node metal connector 9 and locked by the through bolt 10 to form a stable force system.
[0040] The present application provides a stable wooden structure with a large span and long cantilever, which can be used as the skeleton structure of a wooden building to achieve many expansions:

For the sake of ease of observation, only one side of the wooden board 5 is shown in the figure, and the other sides of the wooden board 5 are not shown. The coverage of the roof is the cantilevered area of the cantilevered oblique wooden beams 1, so that an inverted square cone-shaped roof is formed, which can be used as a special-shaped pavilion-like building in scenery and garden landscapes. At the same time, in order to waterproof the roof, anti-corrosion paint can be applied on the surface of each cantilevered oblique wooden beam 1, the secondary wooden beam 4 and the wooden board 5, and then waterproof membrane is laid.
[0042] For another example, a plurality of such structures are combined and equipped with wooden boards 5 to form a number of undulating roofs, and drainage facilities or wells are set up at the wooden frame to be used as a new type of spatial configuration. Similarly, in order to waterproof the roof, anti-corrosion paint can be applied on the surface of each cantilevered inclined wooden beam 1, secondary wooden beam 4 and wooden board 5, and then waterproof membrane can be laid.
