Detailed Implementation

[0019] like Figs. 1 to 4 As shown, this utility model proposes a truss structure for the top of a tower-building machine for tower construction, including a load-bearing plate 1, a fixing rod 2, a fixing block 3, a diagonal brace 4, a truss 5, and a sleeve 6. The fixing block 3 is obliquely fixed at the position of the fixing block 3 and is connected to the truss 5 by the diagonal brace of the fixing block 3. The fixing rod 2 and the sleeve 6 are respectively arranged on both sides of the truss 5, and the fixing rod 2 and the sleeve 6 are arranged correspondingly. The load-bearing plate 1 is arranged on the left and right sides of the truss 5. The thickness of the load-bearing plate 1 is half that of the fixing rod 2. When the fixing rod 2 is embedded in the sleeve 6, the load-bearing plate 1 and the load-bearing plate 1 on the adjacent truss 5 press against each other.

[0020] The fixing rod 2 is provided with a screw hole 21, a spring rod 22, a round tube 23 and an alloy plate 24. The alloy plate 24 is disposed inside the round tube 23, and the screw holes 21 are symmetrically arranged on both sides of the round tube 23. There are two spring rods 22, which are symmetrically distributed with the screw holes 21 as the center, and the spring rods 22 connect the upper and lower alloy plates 24. A bolt passes through the screw hole 21 and the bolt presses against the alloy plate 24. The alloy plate 24 limits the bolt under the elastic force of the spring rod 22.

[0021] Furthermore, the sleeve 6 has a hollow structure in the middle, and the sleeve 6 has a hole corresponding to the screw hole 21. When the fixing rod 2 is inserted into the sleeve 6, the bolt passes through the hole and the screw hole 21, and the alloy plate 24 presses against the bolt to improve the fixing connection effect.

[0022] Furthermore, when the fixing rod 2 and the sleeve 6 are engaged, the force plates 1 on both sides of the truss 5 press against each other and generate directional pressure between adjacent trusses 5, thereby improving the connection effect between the trusses 5.

[0023] Furthermore, the alloy plate 24 has a rubber material in the middle, which has a large friction force. When the bolt passes through the screw hole 21, the elastic force of the spring rod 22 squeezes the rubber material in the middle of the alloy plate 24.

[0024] In this invention, when the trusses 5 are spliced ​​together, the fixing rod 2 is inserted into the sleeve 6 on the adjacent truss 5, so that the bolt passes through the hole and screw hole 21 of the sleeve 6, and the bolt slides on the alloy plate 24 inside the round tube 23. The alloy plate 24 is stretched by the spring rod 22, so that the outer periphery of the bolt is squeezed by the rubber material in the middle of the alloy plate 24, thereby achieving the effect of buffering the bolts connecting the trusses 5, preventing the spliced ​​trusses 5 from shaking and making the connection unstable and easy to loosen.

[0025] The load-bearing plate 1 is provided with a support rod 11, a bending plate 12, a load-bearing block 13, a load-bearing plate 14, a rubber block 15, and a ball block 16. The rubber block 15 is disposed on the side of the support rod 11, and the support rod 11 and the rubber block 15 are disposed on one side of the truss 5. The load-bearing plate 14 is disposed on the other side of the truss 5. The ball blocks 16 are evenly distributed on the load-bearing plate 14. The load-bearing block 13 is disposed at the position of the support rod 11. The bending plate 12 is distributed between two adjacent load-bearing blocks 13. When the ball block 16 presses against the load-bearing block 13, it presses and expands the load-bearing block 13, and causes the bending plate 12 to bend and squeeze the side of the load-bearing plate 14.

[0026] The bending plate 12 is provided with a connecting block 121, a metal block 122 and an arc strip 123. The arc strip 123 is disposed on one side of the connecting block 121 and is fixedly supported on the outside of the force-bearing block 13 by the connecting block 121. The metal block 122 is disposed between two metal blocks 122. When two adjacent force-bearing blocks 13 expand, the connecting block 121 squeezes the arc strip 123 to bend and causes the metal block 122 to move outward elastically. The metal block 122 presses against one side of the load-bearing plate 14.

[0027] Furthermore, the force-bearing block 13 has a "V" shaped structure and a certain degree of elasticity. The force-bearing block 13 is set in relation to the ball block 16. When the fixed rod 2 and the sleeve 6 are embedded, the bearing plate 14 drives the ball block 16 to press against the middle of the force-bearing block 13.

[0028] In this utility model, after the fixing rod 2 is embedded in the sleeve 6 and fixedly connected by bolts, the load-bearing plates 14 and support rods 11 on the two adjacent trusses 5 approach each other, and the ball block 16 on the load-bearing plate 14 presses against the force-bearing block 13 on the support rod 11. At this time, the force-bearing block 13 is pressed and expanded, and the two ends of the bending plate 12 are squeezed close together, so that the connecting block 121 bends the arc strip 123, and the metal block 122 moves outward elastically. At this time, the metal block 122 presses against the side of the load-bearing plate 14, forming the effect of mutual pressure between the two sides of the spliced ​​trusses 5, which provides pressure sealing for the connection of the spliced ​​trusses 5. After the fixing rod 2 and sleeve 6 are embedded and fixed, the stability of the connection is improved, and the trusses 5 are prevented from easily shaking under pressure.

[0029] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
