[0002] Wooden rafter is a Chinese word, which refers to the long wooden strips on the purlins to support the roof panels and tiles. In China, many ancient towns and most large cities still retain some ancient buildings. Ancient Chinese buildings are mainly wooden rafter structures, and it is not easy to preserve them to this day. As time goes by, the structures of many ancient buildings gradually decay and are prone to collapse. In order to maintain the former splendor of ancient buildings, they have to be repaired. The installation structure of wooden rafters in ancient buildings is complex and difficult to disassemble and replace for a long time. However, such wooden rafters are not convenient to disassemble and assemble, which affects the use of the building. Utility Model Content

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-5 This application is described in further detail.

[0020] The present application embodiment discloses a building wooden rafter installation structure. Figure 1-2 , including a first wooden rafter 1, a mounting groove 2 is opened on one side of the first wooden rafter 1, a second wooden rafter 3 is clamped inside the mounting groove 2, plug-in grooves 4 are opened on both sides of the mounting groove 2, a plug-in board 5 is plugged into the plug-in groove 4, the cross-sections of the plug-in groove 4 and the plug-in board 5 are both T-shaped structures, one end of the plug-in board 5 is connected to one side of the second wooden rafter 3, and grooves 6 are opened at both ends of one side of the mounting groove 2.

[0021] Reference Figure 3-5 A fixing cylinder 10 is connected to the middle of the bottom end of the groove 6, and a clamping groove 11 is provided on both sides of the fixing cylinder 10. A spring 12 is connected to the bottom end of the groove 6. The fixing cylinder 10 is located inside the spring 12. The spring 12 is compressed under the movement of the pressure plate 13. When the clamping block 18 is clamped with the clamping groove 11, the spring 12 will apply an upward force in the compressed state, thereby making the connection between the clamping block 18 and the clamping groove more firmly connected. A pressure plate 13 is connected to the upper end of the spring 12. A through hole 14 is provided in the middle of the upper end of the pressure plate 13. The diameter of the through hole 14 is larger than the diameter of the fixing cylinder 10. A rotating button 15 is connected to the upper end of the second wooden rafter 3. The rotating button 15 rotates to drive the connecting column 16 to rotate, so that The block 18 moves to the inside of the clamping groove 11 or moves the block 18 out of the clamping groove 11, and the second wooden rafter 3 moves toward the side of the first wooden rafter 1, so that one end of the connecting column 16 contacts the pressure plate 13. As the pressure plate 13 moves, the spring 12 is squeezed to move the fixing rod 17 to the inside of the fixing tube 10. The block 18 is located inside the clamping groove 11, and the lower end of the rotating button 15 is connected to the connecting column 16, which is located inside the groove 6. The diameter of the connecting column 16 is the same as the diameter of the groove 6. The fixing rod 17 is connected to one side of the connecting column 16, and the fixing rod 17 is connected to the block 18 on both sides of the lower end. The block 18 is located inside the clamping groove 11, and the fixing rod 17 is located inside the fixing tube 10.

[0022] The implementation principle of the wooden rafter installation structure of the embodiment of the present application is as follows: when in use, the rotating button 15 is rotated, the rotating button 15 drives the connecting column 16 to move, and the connecting column 16 drives the fixing rod 17 to move, so that the fixing rod 17 drives the clamping block 18 to move from one end of the clamping groove 11 to the other end. At this time, the clamping block 18 is no longer fixedly connected to the clamping groove 11, and the elastic potential energy of the spring 12 pushes the pressing plate 13 to move upward, and the movement drives the connecting column 16 to move, and then the second wooden rafter 3 is separated from the first wooden rafter 1, so as to facilitate the disassembly of the second wooden rafter 3 and the first wooden rafter 1. When installation is required, the second wooden rafter 3 moves to the side of the first wooden rafter 1, so that the connecting column 16 is located in the groove 6. Inside, at this time, one end of the connecting column 16 is in contact with one side of the pressure plate 13. As the second wooden rafter 3 moves, the pressure plate 13 is pushed. The movement of the pressure plate 13 squeezes the spring 12, so that the fixing rod 17 moves to the inside of the fixing tube 10. The clamping block 18 is located inside the clamping groove 11. The rotating button 15 is rotated to one side. The rotating button 15 drives the connecting column 16 to move, and the connecting column 16 drives the fixing rod 17 to move. The fixing rod 17 drives the clamping block 18 to move, so that the clamping block 18 is clamped with the clamping groove 11. At the same time, the spring 12 will exert an upward force in a compressed state, thereby making the connection between the clamping block 18 and the clamping groove 11 more firmly connected, so that the second wooden rafter 3 and the first wooden rafter 1 are more tightly connected.
