Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a fast-assembly steel structure truss. Background Art

[0002] A steel truss is a frame structure constructed from steel. It's constructed by welding steel components (such as beams, columns, and braces) together to form a stable system capable of bearing and transmitting loads. Trusses are primarily used in places like bridges, stadiums, and aircraft hangars. Their spans are large and require significant storage space. Welded trusses cannot be assembled quickly, making them difficult to transport. They can exceed the load capacity of transport vehicles or be restricted by tunnel and road width limitations.

[0003] Therefore, in order to solve the defect that the welded trusses are difficult to transport due to their large size, it is necessary to propose a rapid assembly steel structure truss. Utility Model Content

[0004] The purpose of the present invention is to provide a quickly assembled steel structure truss. By designing the truss as a detachable module, the size and weight of each module are controlled within a range that is convenient for transportation, thereby avoiding the transportation difficulties caused by the truss being too large, and solving the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] To solve the technical problem of how to quickly assemble the trusses, please refer to Figure 1-Figure 3 , this embodiment provides the following technical solutions:

[0020] A quick-assembly steel structure truss includes an upper chord 1, a lower chord 2, vertical beams 3 detachably mounted on the left and right ends of the upper chord 1 and the lower chord 2, and a cross beam 4 detachably mounted between the front and rear vertical beams 3. Node plates 8 are welded to both ends of the upper chord 1, the lower chord 2, and the cross beam 4. A first plug-in block 81 is welded to the connecting end of the node plate 8. A first slot 31 is provided on the surface of the vertical beam 3 to match the first plug-in block 81. The node plate 8 is fixed to the vertical beam 3 by bolts.

[0021] Specifically, place the vertical beam 3 at the left and right ends of the upper chord 1 and the lower chord 2, ensuring that the first slots 31 on the vertical beam 3 are aligned with the first insert blocks 81 of the upper chord 1 and the lower chord 2, insert the first insert blocks 81 into the first slots 31, ensuring that the insert blocks are fully inserted and fixed in place, and use bolts to fix the gusset plate 8 and the vertical beam 3;

[0022] Then place the crossbeam 4 between the front and rear vertical beams 3, ensuring that the first insert 81 on the crossbeam 4 is aligned with the first slot 31 on the vertical beam 3, insert the first insert 81 into the first slot 31, ensuring that the insert is fully inserted and fixed in place, and use bolts to fix the gusset plate 8 to the vertical beam 3;

[0023] Finally, check all connection points to ensure that the bolts are tight and not loose.

[0024] For technical solutions to the problem of how trusses improve stability, see Figure 3 , this embodiment provides the following technical solutions:

[0025] A web member 6 is supported between the upper chord 1 and the lower chord 2. Connecting plates 61 are welded to the upper and lower ends of the web member 6. A second plug-in block 62 is welded to the connecting end of the connecting plate 61. A second slide groove 9 that is compatible with the second plug-in block 62 is provided on the surface of the upper chord 1 and the lower chord 2. The connecting plate 61 is fixed to the upper chord 1 and the lower chord 2 by bolts.

[0026] Specifically, during installation: place the web 6 between the upper chord 1 and the lower chord 2, and insert the second plug 62 of the connecting plate 61 into the second slide groove 9 of the upper chord 1 and the lower chord 2, ensuring that the plug is fully inserted and fixed in place, use bolts to fix the connecting plate 61 to the upper chord 1 and the lower chord 2, check all connection points, and ensure that the bolts are tightened and not loose.

[0027] It should be noted that the web member 6 transfers the load from the top to the bottom of the truss by connecting the upper chord 1 and the lower chord 2, thereby dispersing the load of the entire structure and reducing the burden on the upper chord 1 and the lower chord 2. At the same time, the presence of the web member 6 increases the stiffness of the truss, making the truss less likely to deform when subjected to external loads, helping to optimize the stress distribution inside the truss, thereby improving the stability and durability of the structure.

[0028] A diagonal bracing beam 7 is reinforced between two adjacent web members 6. The diagonal bracing beam 7 is a steel plate with an inclined angle of 45 degrees. Horizontal plates 71 are welded to both ends of the diagonal bracing beam 7. The horizontal plates 71 are fixed to the connecting plates 61 by bolts.

[0029] Specifically, during installation: place the diagonal bracing beam 7 between two adjacent web members 6, ensure that the inclination angle of the diagonal bracing beam 7 is 45°, and align the horizontal plates 71 at both ends with the connecting plate 61, use bolts to fix the horizontal plates 71 to the connecting plate 61, check all connection points to ensure that the bolts are tightened and not loose.

[0030] It should be noted that the diagonal bracing beam 7 is installed at an inclination angle of 45°, which can effectively resist lateral forces such as wind loads or earthquake forces, thereby increasing the lateral resistance of the truss, transferring the load from one side of the truss to the other side, dispersing the load of the entire structure, and reducing the burden on the web member 6 and the chord member.

[0031] A cross link 5 is inserted between the two upper chords 1 and the two lower chords 2 arranged in the front and rear. The cross link 5 is a round tube with a diameter of 5 cm. The surfaces of the upper chords 1 and the lower chords 2 are provided with through holes 10 that are compatible with the cross link 5. The front and rear ends of the cross link 5 pass through the through holes 10 and are fixed by nuts.

[0032] Specifically, during installation: place the cross link 5 between the two upper chords 1 and the two lower chords 2 set in the front and rear, pass the front and rear ends of the cross link 5 through the corresponding through-holes 10, use nuts to tighten the front and rear ends of the cross link 5, check all connection points, and ensure that the nuts are tightened and not loose.

[0033] It should be noted that the cross link 5 passes through the through holes 10 of the upper chord 1 and the lower chord 2, providing lateral support, increasing the stability of the truss in the horizontal direction, preventing the truss from shifting or twisting under the action of lateral force, and increasing the stiffness of the entire truss, making the truss less likely to deform when subjected to external loads.

[0034] Working principle: When assembling this fast-assembly steel structure truss, place the vertical beam 3 at the left and right ends of the upper chord 1 and the lower chord 2, and align the first plug-in block 81 of the upper chord 1 and the lower chord 2 with the first slot 31 on the vertical beam 3 to ensure that the plug-in block is fully inserted and fixed in place, use bolts to fix the node plate 8 and the vertical beam 3, then place the cross beam 4 between the front and rear vertical beams 3, and align the first plug-in block 81 on the cross beam 4 with the first slot 31 on the vertical beam 3 to ensure that the plug-in block is fully inserted and fixed in place, use bolts to fix the node plate 8 and the vertical beam 3, place the web member 6 between the upper chord 1 and the lower chord 2, and align the second plug-in block 62 of the connecting plate 61 with the first slot 31 on the vertical beam 3 to ensure that the plug-in block is fully inserted and fixed in place, Insert the block into the second slide groove 9 of the upper chord 1 and the lower chord 2, make sure that the insert is fully inserted and fixed in place, use bolts to fix the connecting plate 61 to the upper chord 1 and the lower chord 2, then place the diagonal bracing beam 7 between the two adjacent web members 6, make sure that the inclination angle of the diagonal bracing beam 7 is 45°, and align the horizontal plates 71 at both ends with the connecting plate 61, use bolts to fix the horizontal plate 71 to the connecting plate 61, then place the cross link 5 between the two upper chords 1 and the two lower chords 2 set in the front and rear, and pass the front and rear ends of the cross link 5 through the corresponding through-holes 10, and then tighten the front and rear ends of the cross link 5 with nuts, and finally check all connection points to make sure that the nuts are tightened and not loose.
