Description

Technical Field

[0001] This invention relates to the field of steel structure technology, specifically to a high-safety torsion-resistant steel structure truss and its torsion-resistant method. Background Technology

[0002] A truss is a structural component made up of connected members. It can make full use of the strength of materials. When the span is large, it can save materials compared with solid web beams, reduce self-weight and increase stiffness. It is widely used in the construction of various steel structure supports.

[0003] When installing existing support trusses, the joints are usually fixed by welding or multiple screws. For example, in the patent with publication number CN218091292U, the horizontal and vertical bars are fixedly connected by fixing screws, and the support rods are also fixed to the horizontal and vertical bars by fixing screws. The large number of screws makes the installation work cumbersome and labor-intensive. In addition, the fixing screws are subjected to force, which can easily cause the fixing screws to bend and deform, reduce the strength of the equipment, and make it difficult to disassemble later. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for steel structure trusses that achieves high strength and is easy to install and disassemble.

[0005] The objective of this invention can be achieved through the following technical solutions: A high-safety torsion-resistant steel truss includes a first support tube and a second support tube. A connecting tube is fixedly installed on the side of the first support tube, and the second support tube is slidably installed on the connecting tube. The connecting tube has multiple sets of spaced first limiting grooves, and the second support tube has two sets of second limiting grooves corresponding to the positions of the first limiting grooves. The first and second support tubes are jointly provided with ribs. A first connecting plate and a base plate are fixedly installed at both ends of the ribs, and a second connecting plate is fixedly installed on the base plate. The second connecting plate is inserted into the first and second limiting grooves away from the first support tube. The base plate is in contact with the surface of the second support tube, and the first connecting plate is in contact with the surface of the first support tube. A U-shaped first limiting plate is slidably installed inside the first support tube. A first adjusting screw that drives the first limiting plate to move is threaded onto the first support tube. When the first limiting plate extends out of the first support tube, its two sets of sidewalls simultaneously contact the two sides of the first connecting plate.

[0006] Preferably, a reinforcing plate is fixedly installed on the rib, the reinforcing plate is inserted into the first limiting groove and the second limiting groove near the first support tube, and a base plate that contacts the surface of the second support tube is also fixedly installed on the reinforcing plate.

[0007] Preferably, an L-shaped support plate is fixedly installed on the side of the first support tube, the support plate is located inside the connecting tube and a U-shaped second limiting plate is slidably installed on the support plate, a second adjusting screw that drives the second limiting plate to move is threaded on the first support tube, and the second limiting plate is used in conjunction with multiple sets of third limiting grooves opened on the reinforcing plate.

[0008] Preferably, two sets of mounting plates are fixedly installed on the side of the first support tube. The mounting plates are distributed on both sides of the rib and are located at the position where the first connecting plate contacts the first support tube. The mounting plates are provided with covers that contact the side of the first support tube.

[0009] Preferably, two sets of connecting rods that penetrate the mounting plate are fixedly installed on the cover. The connecting rods and nuts cooperate to fix the cover. A baffle is fixedly installed at the end of the cover away from the first support tube. The baffle and the rib are spaced apart.

[0010] Preferably, a partition is fixedly installed inside the cover. The partition has an L-shaped cross-section and one side surface of the partition is in contact with the first support tube. A sponge is fixedly installed on the partition. A water outlet groove is fixedly installed on the cover, and the water outlet groove is connected to the area where the sponge is located.

[0011] Preferably, a shielding ring is fixedly installed on the substrate. The shielding ring works in conjunction with a protective ring fixedly installed on the second support tube. The protective ring is distributed around the second limiting groove and is located in the projection area of ​​the shielding ring onto the second support tube. The shielding ring has an L-shaped cross-section and the lower surface of the vertical section of the shielding ring is lower than the upper surface of the protective ring.

[0012] Preferably, an elastic membrane is fixedly installed on the inner side of the vertical section of the shielding ring, and an elastic coil is fixedly connected to the side of the elastic membrane away from the shielding ring. The elastic coil is in contact with the protective ring, and a positioning plate for limiting the position of the elastic coil is fixedly installed on the side of the protective ring.

[0013] This invention also provides a method for resisting torsion in steel trusses, which is applied to the aforementioned high-safety torsion-resistant steel truss, and includes the following steps: Step S1: First, install the second support tube onto the connecting tube until the side of the second support tube contacts the side of the first support tube; Step S2: Insert the second connecting plate into the aligned first and second limiting grooves away from the first support tube, and move the second connecting plate downward until the substrate contacts the surface of the second support tube. Step S3: Rotate the first adjusting screw to move the first limiting plate to the outside of the first support tube. After the first limiting plate moves out of the first support tube, the first connecting plate is located between the two side walls of the first limiting plate, completing the assembly of the device. The first support tube, the second support tube and the rib plate form a stable triangular structure for support.

[0014] The beneficial effects of this invention are: (1) In this invention, the first connecting plate is restricted by the first limiting plate, so that the rib cannot move in the length direction of the first supporting tube. The second supporting tube is fixed on the connecting tube by the cooperation of the second connecting plate with the first limiting groove and the second limiting groove. At the same time, the rib cannot move in the length direction of the second supporting tube, thus realizing mutual restriction and locking between the components, avoiding a large number of screws for connection and fixing, improving the efficiency of device installation and disassembly. When in use, the first supporting tube, the second supporting tube and the rib form a stable triangular structure, improving the torsional strength and stability of the device. At the same time, when the device is subjected to force, it is all borne by the first supporting tube, the second supporting tube and the rib, avoiding the deformation caused by insufficient strength of the fixing screws and other fasteners, improving the overall strength of the device and facilitating subsequent disassembly.

[0015] (2) In this invention, the area where the first connecting plate is located is shielded on three sides by the mounting plate, cover and baffle, so as to prevent rainwater from falling directly into the area where the coating peels off due to friction contact between the first connecting plate and the first limiting plate, thereby reducing the probability of component corrosion, improving the service life of the component and the strength of the device. The sponge absorbs the rainwater flowing along the side wall of the first support pipe. After absorbing the rainwater, the sponge can flow away from the side of the first support pipe. Finally, the rainwater gathers at the bottom of the partition and is discharged through the water outlet, further reducing the probability of rainwater contacting the area where the coating peels off, improving the service life of the component and the strength of the device.

[0016] (3) In this invention, the second support tube is shielded by a shielding ring and a protective ring to prevent rainwater from falling into the area where the substrate and the second support tube rub against each other and the coating is damaged. At the same time, the elastic coil will contact the protective ring, so that the elastic membrane can cover the gap between the shielding ring and the protective ring, further improving the protection of the area where the substrate is located, further reducing the probability of rainwater contacting the area where the coating falls off, and improving the service life of the component and the strength of the device.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-10As shown, the present invention is a high-safety torsion-resistant steel structure truss, including a first support pipe 1 and a second support pipe 2. A connecting pipe 3 is fixedly installed on the side of the first support pipe 1, and the second support pipe 2 is slidably installed on the connecting pipe 3. The connecting pipe 3 has multiple sets of spaced first limiting grooves 4, and the second support pipe 2 has two sets of second limiting grooves 10 corresponding to the positions of the first limiting grooves 4. The first support pipe 1 and the second support pipe 2 are jointly provided with a rib plate 13. A first connecting plate 14 and a base plate 15 are fixedly installed at both ends of the rib plate 13, respectively. A second connecting plate 16 is fixedly installed on the base plate 15. The second connecting plate 16 is inserted into the first limiting groove 4 and the second limiting groove 10 away from the first support pipe 1. The base plate 15 is in contact with the surface of the second support pipe 2, and the first connecting plate 14 is in contact with the surface of the first support pipe 1.

[0031] A U-shaped first limiting plate 6 is slidably installed inside the first support tube 1. A first adjusting screw 7 that drives the first limiting plate 6 to move is threaded onto the first support tube 1. When the first limiting plate 6 extends out of the first support tube 1, its two sets of side walls simultaneously contact the two sides of the first connecting plate 14.

[0032] In practical application, the second support tube 2 is first installed onto the connecting tube 3 until the second support tube 2 contacts the side of the first support tube 1. Then, the second connecting plate 16 is inserted into the aligned first limiting groove 4 and second limiting groove 10, away from the first support tube 1. The second connecting plate 16 is moved downwards until the base plate 15 contacts the surface of the second support tube 2. At this point, the rib plate 13 can be installed onto the second support tube 2, and simultaneously, the first connecting plate 14 contacts the side of the first support tube 1. Then, the first adjusting screw 7 is rotated to move the first limiting plate 6 to the outside of the first support tube 1. After the first limiting plate 6 moves out of the first support tube 1, the first connecting plate 14 is located between the two side walls of the first limiting plate 6. This completes the assembly of the device. The first connecting plate 14 is then positioned using the first limiting plate 6. 4. By restricting the movement of the rib plate 13 along the length of the first support tube 1, the second support tube 2 is fixed to the connecting tube 3 through the cooperation of the second connecting plate 16 with the first limiting groove 4 and the second limiting groove 10. At the same time, the rib plate 13 cannot move along the length of the second support tube 2, thus achieving mutual restriction and locking between the components, avoiding the need for a large number of screws for connection and fixing, and improving the efficiency of device installation and disassembly. In use, the first support tube 1, the second support tube 2 and the rib plate 13 form a stable triangular structure, which improves the torsional strength and stability of the device. At the same time, when the device is subjected to force, it is all borne by the first support tube 1, the second support tube 2 and the rib plate 13, avoiding deformation due to insufficient strength of fixing screws and other fasteners, improving the overall strength of the device and facilitating subsequent disassembly.

[0033] Please see Figure 2 , Figure 4As shown, a reinforcing plate 20 is fixedly installed on the rib plate 13. The reinforcing plate 20 is inserted into the first limiting groove 4 and the second limiting groove 10 near the first support tube 1. A base plate 15 that contacts the surface of the second support tube 2 is also fixedly installed on the reinforcing plate 20.

[0034] Specifically, an L-shaped support plate 5 is fixedly installed on the side of the first support pipe 1. The support plate 5 is located inside the connecting pipe 3 and a U-shaped second limiting plate 8 is slidably installed on the support plate 5. A second adjusting screw 9 that drives the second limiting plate 8 to move is threaded on the first support pipe 1. The second limiting plate 8 is used in conjunction with multiple sets of third limiting grooves 21 opened on the reinforcing plate 20.

[0035] In practical application, when the rib plate 13 is installed, the reinforcing plate 20 is simultaneously inserted into the aligned first limiting groove 4 and second limiting groove 10. At the same time, the base plate 15 contacts the surface of the second support tube 2. Then, the second adjusting screw 9 is rotated, which drives the second limiting plate 8 to move and insert into the third limiting groove 21. The second limiting plate 8 restricts the reinforcing plate 20, further increasing the restriction of the rib plate 13 in the length direction of the first support tube 1. At the same time, the reinforcing plate 20 can further form a new triangular structure with the first support tube 1, the second support tube 2, and the rib plate 13, further improving the torsional strength and overall stability of the device.

[0036] Please see Figures 1-10 As shown, two sets of mounting plates 22 are fixedly installed on the side of the first support tube 1. The mounting plates 22 are distributed on both sides of the rib plate 13 and are located at the position where the first connecting plate 14 contacts the first support tube 1. A cover 23 is provided on the mounting plate 22 that contacts the side of the first support tube 1.

[0037] Specifically, two sets of connecting rods 24 that penetrate the mounting plate 22 are fixedly installed on the cover 23. The connecting rods 24 and nuts are used to fix the cover 23. A baffle 27 is fixedly installed at the end of the cover 23 away from the first support tube 1. The baffle 27 and the rib plate 13 are spaced apart.

[0038] A partition 25 is fixedly installed inside the cover 23. The partition 25 has an L-shaped cross section and one side surface of the partition 25 is in contact with the first support pipe 1. A sponge 26 is fixedly installed on the partition 25. A water outlet trough 28 is fixedly installed on the cover 23. The water outlet trough 28 is connected to the area where the sponge 26 is located.

[0039] A shielding ring 17 is fixedly mounted on the substrate 15. The shielding ring 17 works in conjunction with a protective ring 11 fixedly mounted on the second support tube 2. The protective ring 11 is distributed around the second limiting groove 10. The protective ring 11 is located in the projection area of ​​the shielding ring 17 onto the second support tube 2. The shielding ring 17 has an L-shaped cross section and the lower surface of the vertical section of the shielding ring 17 is lower than the upper surface of the protective ring 11.

[0040] An elastic membrane 18 is fixedly installed on the inner side of the vertical section of the shielding ring 17. An elastic coil 19 is fixedly connected to the side of the elastic membrane 18 away from the shielding ring 17. The elastic coil 19 is in contact with the protective ring 11. A positioning plate 12 for limiting the position of the elastic coil 19 is fixedly installed on the side of the protective ring 11.

[0041] In practical application, after the rib plate 13 is installed and fixed, the cover 23 is installed onto the mounting plate 22 via the connecting rod 24. The cover 23 is then fixed onto the mounting plate 22 by the fixing nut and the connecting rod 24. At this time, the area where the first connecting plate 14 is located is shielded on three sides by the mounting plate 22, the cover 23 and the baffle 27, thereby preventing rainwater from falling directly onto the area where the coating peels off due to friction between the first connecting plate 14 and the first limiting plate 6, reducing the probability of component corrosion, and improving the service life of the component and the strength of the device.

[0042] When a small amount of rainwater flows downward along the side of the cover 23 that contacts the first support pipe 1, the sponge 26 absorbs the rainwater flowing along the side wall of the first support pipe 1. After absorbing the rainwater, the sponge 26 can flow away from the side of the first support pipe 1. Finally, the rainwater gathers at the bottom of the partition 25 and is discharged through the water outlet 28, further reducing the probability of rainwater contacting the area where the coating peels off, and improving the service life of the components and the strength of the device.

[0043] The second support tube 2 is shielded by a shielding ring 17 and a protective ring 11 to prevent rainwater from falling onto the area where the substrate 15 rubs against the second support tube 2, causing damage to the coating. At the same time, the elastic coil 19 will contact the protective ring 11, so that the elastic membrane 18 can cover the gap between the shielding ring 17 and the protective ring 11, further improving the protection of the area where the substrate 15 is located, further reducing the probability of rainwater contacting the area where the coating falls off, improving the service life of the component and the strength of the device, and preventing the elastic coil 19 from falling off the protective ring 11 upwards by the positioning plate 12.

[0044] Please see Figures 1-10 As shown, a method for resisting torsion in a steel truss structure, applied to the aforementioned high-safety torsion-resistant steel truss structure, includes the following steps: Step S1: First, install the second support tube 2 onto the connecting tube 3 until the second support tube 2 contacts the side of the first support tube 1.

[0045] Step S2: Insert the second connecting plate 16 into the aligned first limiting groove 4 and second limiting groove 10 away from the first support tube 1, and move the second connecting plate 16 downward until the substrate 15 contacts the surface of the second support tube 2.

[0046] Step S3: Rotate the first adjusting screw 7 to move the first limiting plate 6 to the outside of the first support tube 1. After the first limiting plate 6 moves out of the first support tube 1, the first connecting plate 14 is located between the two side walls of the first limiting plate 6, completing the assembly of the device. The device is supported by a stable triangular structure formed by the first support tube 1, the second support tube 2 and the rib plate 13.

[0047] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
