Technical Field

[0001] The invention belongs to the technical field of steel structures, and in particular relates to a cradle for assembling an inverted triangle truss. Background Art

[0002] In recent years, with the strengthening of national economic strength, the needs of social development and the guidance of national policies, large-span space steel structures have received more and more attention. As one of the commonly used large-span space steel structures, the application of steel tube truss structure system is particularly favored by the market. After decades of research and development, its related technologies have become increasingly mature and have been widely recognized by the market. Due to the complexity of the truss and high welding requirements of this type of structural system, it is generally assembled on the ground by on-site welding and then hoisted and installed.

[0003] The prior art uses an assembled frame to weld and fix the inverted triangle truss, fixes the upper chord and the lower chord, and then welds the web between the upper chord and the lower chord. When the inverted triangle truss needs to be made into a shape with one end wide and the other end narrow, the upper chord needs to be tilted. The prior art cannot accurately position the upper chord, resulting in reduced welding quality of the inverted triangle truss. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and to provide a cradle for assembling an inverted triangle truss, which can accurately position the chord at the top and the chord at the bottom, adjust the inclination of the chord at the top, improve the welding quality of the inverted triangle truss, shorten the splicing time of the inverted triangle truss, and obtain an inverted triangle truss with a wide end and a narrow end.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A frame for assembling an inverted triangle truss, characterized in that it includes a mounting frame, an adjustment device, a clamping device 1 and a clamping device 2, wherein the adjustment device moves vertically on the mounting frame and is fixed, the clamping device 1 moves vertically on the mounting frame and is supported on the adjustment device, the clamping device 1 is used to clamp the chord bar at the top, the clamping device 2 is fixed at the bottom of the mounting frame, and the clamping device 2 is used to clamp the chord bar at the bottom, and when the installation positions of the upper chord bar and the lower chord bar are determined, the web bar is welded between the upper chord bar and the lower chord bar to form the entire inverted triangle truss.

[0007] The present invention moves the adjustment device vertically on the mounting frame to adjust the installation position of the adjustment device on the mounting frame. When the clamping device 1 is supported on the adjustment device, the installation position of the clamping device 1 on the mounting frame can be adjusted. When the clamping device 1 clamps the chord bar at the top and the clamping device 2 clamps the chord bar at the bottom, the chord bar at the top and the chord bar at the bottom can be accurately positioned, and the inclination of the chord bar at the top can be adjusted to improve the welding quality of the inverted triangle truss, shorten the splicing time of the inverted triangle truss, and obtain an inverted triangle truss with a wide end and a narrow end. When the chord bar at the top is adjusted to a horizontal state, the two ends of the inverted triangle truss are the same. This allows the assembly frame to be suitable for the splicing of different types of inverted triangle trusses, has a wide range of applications, and meets construction needs.

[0008] Furthermore, the mounting frame includes a frame and a snap plate, the snap plate is vertically welded to the frame, the adjustment device includes a connecting plate 1, a connecting plate 2 and a bolt 1, the connecting plate 1 is provided with a protrusion 1, the snap plate is provided with a sliding groove, the protrusion 1 is embedded in the sliding groove and moves vertically in the sliding groove, and the protrusion 1 and the sliding groove are in a T shape. The connecting plate 1 and the connecting plate 2 are fixed by bolt 1, so that the connecting plate 1 and the connecting plate 2 are clamped on the snap plate. The structure of the mounting frame and the adjustment device is specifically designed so that the adjustment device can move in a directional manner on the mounting frame, and the connection between the connecting plate 1 and the connecting plate 2 does not affect the snap plate.

[0009] Furthermore, a threaded rod 1 is vertically welded to the frame, and the threaded rod 1 passes through a connecting plate 2. The threaded rod 1 is threadedly connected with a nut 1. Two pairs of nuts are used on the single threaded rod 1 to fix the connecting plate 2, thereby further fixing the adjustment device, so that the force applied to the adjustment device can be transmitted to the frame through the threaded rod 1, thereby increasing the load-bearing capacity of the adjustment device and meeting the fixing requirements of the chord rod above.

[0010] Furthermore, a reinforcing component is fixed between two adjacent snap plates to increase the connection strength between the two adjacent snap plates and improve the stability of the entire mounting frame.

[0011] Furthermore, the reinforcing component includes round tube one and round tube two, round tube two is cross-welded between two adjacent snap plates, and round tube one is horizontally welded between two adjacent snap plates, thereby increasing the connection strength between the two adjacent snap plates, preventing deformation of the mounting frame, and ensuring the installation of the adjustment device, clamping device one, and clamping device two.

[0012] Furthermore, when the inverted triangle trusses are spliced, the upper chord is at a certain height of the mounting frame, so the upper chord needs to be suspended and installed. How to fix the suspended upper chord is a technical problem that needs to be solved by those skilled in the art. The present invention specifically designs a clamping device 1: the clamping device 1 includes a connecting plate 3, a clamping plate 1 and a clamping plate 2. The connecting plate 3 is provided with a protrusion 2, which is embedded in the sliding groove and moves vertically in the sliding groove. The connecting plate 3 is supported on the connecting plate 1, the clamping plate 1 is welded to the connecting plate 3, the connecting plate 3 is fixed with a fixed plate 1, the clamping plate 2 is fixed with a movable rod, the movable rod passes through the fixed plate 1 and moves along the length direction of the connecting plate 3, the outer end of the movable rod is fixed with a connecting plate 4, and a spring is provided between the connecting plate 4 and the fixed plate 1. When the upper chord is embedded in the area between the clamping plate 1 and the clamping plate 2, the clamping plate 2 moves on the fixing plate 1, and the spring is compressed at this time. Under the deformation of the compressed spring, the clamping plate 1 and the clamping plate 2 clamp and fix the upper chord. This clamping method is a semi-open automatic clamping method, which is suitable for fixing the suspended chord and can clamp and fix chords of different specifications, and has a wide range of applications. In order to allow the upper chord to push the clamping plate 2, the present invention welds an outwardly curved arc plate at the top of the clamping plate 2, and the arc plate guides the upper chord. When the upper chord is not installed between the clamping plate 1 and the clamping plate 2, the upper chord contacts the arc plate. When the upper chord falls, the upper chord pushes the clamping plate 2, so that the clamping plate 2 moves and quickly clamps the upper chord.

[0013] Furthermore, the lower chord in the present invention supports the upper chord and web, so the lower chord needs to be fixed. The present invention specifically designs the clamping device 2: the clamping device 2 includes a base, a fixing plate 2 and a clamping plate, the base is fixed on the frame, and two fixing plates 2 are used to fix the base, the clamping plate is fixed with a threaded rod 2, and the threaded rod 2 is threadedly connected to the fixing plate 2, and the threaded rod 2 is manually screwed so that the two clamping plates clamp the lower chord, thereby increasing the firmness of the clamping of the lower chord, so that the lower chord stably supports the upper chord and web, thereby improving the welding quality between the lower chord and web, and at the same time improving the welding quality between the upper chord and web.

[0014] Furthermore, when the inverted triangle trusses are spliced, the upper chord and the lower chord will still move during the welding process, which reduces the splicing quality of the inverted triangle trusses. In response to this technical problem, the present invention provides a stable bracket, a fixed structure one and a fixed structure two. The stable bracket includes a fixed plate three and a fixed plate four, the fixed plate three is fixed on the mounting frame, the lower chord passes through the fixed plate three, the fixed plate three is fixed with a threaded rod three, the fixed plate four is fixed to the threaded rod three by screws, the threaded rod three is movable with a vertical baffle, the threaded rod three is threadedly connected with a nut two, two nuts two are used on the single threaded rod three to clamp and fix the baffle, the fixed structure one is fixed on the baffle, and the fixed structure two is fixed on the fixed plate four. The outer end of the chord at the top is fixed by the fixing structure 1, and the fixing structure 1 is limited on the threaded rod 3 by the baffle plate, so as to limit the outer end of the upper chord to prevent the upper chord from moving during welding, and ensure that the two upper chords are arranged in parallel; the fixing structure 2 is used to fix the outer end of the chord at the bottom, and the fixing structure 2 is fixed on the fixing plate 4 to prevent the lower chord from moving during welding. When the inverted triangle truss is spliced, the upper chord and the lower chord are less affected by external forces during the welding process, thereby improving the splicing quality of the inverted triangle truss. In addition, the installation position of the baffle plate on the threaded rod 3 can be adjusted, and then the length of the upper chord extending out of the assembly frame can be adjusted to meet the size requirements of the inverted triangle truss.

[0015] Furthermore, the fixing structure 1 includes two hoop plates 1, a connecting rod and a fixing plate 5. The two hoop plates 1 are fixedly connected by bolts 2, so that the two hoop plates 1 clamp the outer ends of the chord rods at the top. The hoop plate 1 fixes the limiting plate. The connecting rod is provided with a limiting groove. The limiting plate is arranged in the limiting groove. The limiting plate is threadedly connected to the limiting rod. The connecting rod is provided with an adjustment hole. The adjustment hole and the limiting groove are connected. The limiting rod passes through the adjustment hole. The limiting rod is threadedly connected with a nut 3. The nut 3 is tightened on the connecting rod. The fixing plate 5 is fixed to the connecting rod by screws, and the fixing plate 5 is fixed to the baffle. When the upper chord rod in the present invention is tilted, the hoop plate 1 is also tilted. At this time, the connecting rod will also be in a tilted state, and the connecting ends of the two connecting rods cannot be aligned. In response to this technical problem, the present invention can rotate and move the connecting rod on the limit rod. When the hoop plate 1 is tilted, the connecting rod can be adjusted to a horizontal state, and the connecting ends of the two connecting rods can be aligned, so that the connecting ends of the connecting rods are used to install the fixing plate 5. The screws between the fixing plate 5 and the connecting rod are screwed in horizontally to avoid the situation where the screws are stuck. At the same time, the fixing plate 5 is in a vertical state, and the fixing plate 5 and the baffle can be tightly fixed, increasing the firmness of the connection between the fixing plate 5 and the baffle, and facilitating the upper chord rod to be transferred to the stable bracket through the fixing structure 1 and the baffle. Moreover, the fixing of the fixing structure 1 and the baffle can meet the requirement of limiting the upper chord rod at a certain height.

[0016] Furthermore, since the chord rod at the bottom is fixed at the bottom of the assembly tire frame, the fixing structure 2 is directly connected to the fixing plate 4. The present invention has a specific design for the fixing structure 2: the fixing structure 2 includes two hoop plates 2, and a tension bolt is provided between the two hoop plates 2. The tension bolt is provided with a nut 4, which holds the outer end of the chord rod at the bottom. The hoop plates 2 are fixed with a threaded rod 4, and the threaded rod 4 passes through the fixing plate 4. The threaded rod 4 is threadedly connected with a nut 5. Two nuts 5 are used to clamp and fix the single threaded rod 4 on the fixing plate 4. The hoop plates 2 are fixed to the fixing plate 4 through the threaded rods 4, and the fixing method for the chord rod at the bottom is simple.

[0017] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0018] 1. The present invention moves the adjustment device vertically on the mounting frame to adjust the installation position of the adjustment device on the mounting frame. When the clamping device 1 is supported on the adjustment device, the installation position of the clamping device 1 on the mounting frame can be adjusted. When the clamping device 1 clamps the chord bar at the top and the clamping device 2 clamps the chord bar at the bottom, the chord bar at the top and the chord bar at the bottom can be accurately positioned, and the inclination of the chord bar at the top can be adjusted to improve the welding quality of the inverted triangle truss, shorten the splicing time of the inverted triangle truss, and obtain an inverted triangle truss with a wide end and a narrow end. When the chord bar at the top is adjusted to a horizontal state, the two ends of the inverted triangle truss are the same. This allows the assembly frame to be suitable for the splicing of different types of inverted triangle trusses, with a wide range of applications to meet construction needs.

[0019] 2. The present invention adopts steel materials, which can be recycled.

[0020] 3. The present invention has a clear principle and low requirements for the operating environment, which is conducive to its application in different complex field environments and has a wide range of promotion. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] like Figures 1 to 14 As shown, a frame for assembling an inverted triangle truss of the present invention comprises a mounting frame 1, an adjusting device 2, a clamping device 1 3 and a clamping device 2 4, and the mounting frame 1, the adjusting device 2, the clamping device 1 3 and the clamping device 2 4 are all made of steel. The adjusting device 2 moves vertically on the mounting frame 1 and is fixed, the clamping device 1 3 moves vertically on the mounting frame 1 and is supported on the adjusting device 2, the clamping device 1 3 is used to clamp the chord 19 at the top, the clamping device 2 4 is fixed at the bottom of the mounting frame 1, and the clamping device 2 4 is used to clamp the chord 19 at the bottom. When the installation positions of the upper chord 19 and the lower chord 19 are determined, a web 51 is welded between the upper chord 19 and the lower chord 19 to form the entire inverted triangle truss. The present invention moves the adjustment device 2 vertically on the mounting frame 1 to adjust the installation position of the adjustment device 2 on the mounting frame 1. When the clamping device 1 3 is supported on the adjustment device 2, the installation position of the clamping device 1 3 on the mounting frame 1 can be adjusted. When the clamping device 1 3 clamps the chord 19 at the top and the clamping device 2 4 clamps the chord 19 at the bottom, the chord 19 at the top and the chord 19 at the bottom can be accurately positioned, and the inclination of the chord 19 at the top can be adjusted to improve the welding quality of the inverted triangle truss, shorten the splicing time of the inverted triangle truss, and obtain an inverted triangle truss with a wide end and a narrow end. When the chord 19 at the top is adjusted to a horizontal state, the two ends of the inverted triangle truss are the same. This allows the assembly frame to be suitable for the splicing of different types of inverted triangle trusses, has a wide range of applications, and meets construction needs.

[0038] The mounting frame 1 includes a frame 5 and a snap plate 6, the snap plate 6 is vertically welded on the frame 5, the adjustment device 2 includes a connecting plate 14, a connecting plate 2 13 and a bolt 15, the connecting plate 14 is provided with a protrusion 16, the snap plate 6 is provided with a sliding groove 54, the protrusion 16 is embedded in the sliding groove 54, and moves vertically in the sliding groove 54, the protrusion 16 and the sliding groove 54 are in a T shape. The connecting plate 14 and the connecting plate 2 13 are fixed by bolts 15, so that the connecting plate 14 and the connecting plate 2 13 are clamped on the snap plate 6. The specific design of the structures of the mounting frame 1 and the adjustment device 2 enables the adjustment device 2 to move in a directional manner on the mounting frame 1, and the connection between the connecting plate 14 and the connecting plate 2 13 does not affect the snap plate 6. The frame 5 is vertically welded with a threaded rod 17, which passes through the connecting plate 2 13. The threaded rod 17 is threadedly connected with a nut 18. Two nuts 18 are used on a single threaded rod 17 to fix the connecting plate 2 13, and the adjustment device 2 is further fixed, so that the force applied to the adjustment device 2 can be transmitted to the frame 5 through the threaded rod 17, thereby increasing the bearing capacity of the adjustment device 2 and meeting the fixing requirements of the chord 19 above. A reinforcement component is fixed between two adjacent snap plates 6 to increase the connection strength between the two adjacent snap plates 6 and improve the stability of the entire mounting frame 1. The reinforcement component includes a round tube 18 and a round tube 27. The round tube 27 is cross-welded between the two adjacent snap plates 6, and the round tube 18 is horizontally welded between the two adjacent snap plates 6 to increase the connection strength between the two adjacent snap plates 6, prevent the mounting frame 1 from deforming, and ensure the installation of the adjustment device 2, the clamping device 1 3, and the clamping device 2 4.

[0039] When the inverted triangle truss is spliced, the upper chord 19 is at a certain height of the mounting frame 1, so the upper chord 19 needs to be suspended and installed. How to fix the suspended upper chord 19 is a technical problem that needs to be solved by those skilled in the art. The present invention specifically designs the clamping device 3: the clamping device 3 includes a connecting plate 3 22, a clamping plate 1 20 and a clamping plate 2 21. The connecting plate 3 22 is provided with a protrusion 2 52, which is embedded in the sliding groove 54 and moves vertically in the sliding groove 54. The connecting plate 3 22 is supported on the connecting plate 1 14, and the clamping plate 1 20 is welded to the connecting plate 3 22. At the same time, a stiffening plate 27 is welded between the clamping plate 1 20 and the connecting plate 3 22. The stiffening plate 27 can be designed to be trapezoidal. The connection plate 3 22 is welded with a fixed plate 1 23, and the clamping plate 21 is fixed with a movable rod 25. The movable rod 25 passes through the fixed plate 1 23 and moves along the length direction of the connection plate 3 22. The outer end of the movable rod 25 is welded with a connection plate 4 24, and a spring 26 is arranged between the connection plate 4 24 and the fixed plate 1 23. When the upper chord 19 is embedded in the area between the clamping plate 1 20 and the clamping plate 2 21, the clamping plate 2 21 moves on the fixed plate 1 23, and the spring 26 is compressed at this time. Under the deformation action of the compressed spring 26, the clamping plate 1 20 and the clamping plate 2 21 clamp and fix the upper chord 19. This clamping method is a semi-open automatic clamping, which is suitable for fixing the suspended chord 19, and can clamp and fix chords 19 of different specifications, and has a wide range of applications. In order to allow the upper chord 19 to push the clamping plate 21, the present invention welds an outwardly bent arc plate 53 at the top of the clamping plate 21, and the arc plate 53 guides the upper chord 19. When the upper chord 19 is not installed between the clamping plate 1 20 and the clamping plate 2 21, the upper chord 19 is in contact with the arc plate 53. When the upper chord 19 falls, the upper chord 19 pushes the clamping plate 21, so that the clamping plate 21 moves and quickly clamps the upper chord 19.

[0040] In the present invention, the lower chord 19 supports the upper chord 19 and the web 51, so the lower chord 19 needs to be fixed. The present invention specifically designs the clamping device 24: the clamping device 24 includes a base 9, a fixing plate 212 and a clamping plate 11, the base 9 is welded to the frame 5, two fixing plates 212 are welded to the base 9, the clamping plate 11 is welded with a threaded rod 210, and the threaded rod 210 is threadedly connected to the fixing plate 212, and the threaded rod 210 is manually screwed to clamp the lower chord 19, thereby increasing the firmness of the clamping of the lower chord 19, so that the lower chord 19 stably supports the upper chord 19 and the web 51, thereby improving the welding quality between the lower chord 19 and the web 51, and at the same time improving the welding quality between the upper chord 19 and the web 51.

[0041] When the inverted triangle truss is spliced, the upper chord 19 and the lower chord 19 will still move during the welding process, which reduces the splicing quality of the inverted triangle truss. In response to this technical problem, the present invention provides a stabilizing bracket 28, a fixing structure 1 29 and a fixing structure 2 30. The stabilizing bracket 28 includes a fixing plate 3 31 and a fixing plate 4 32. The fixing plate 3 31 is fixed to the frame 5 of the mounting frame 1 by screws. The lower chord 19 passes through the fixing plate 3 31. The fixing plate 3 31 is fixed with a threaded rod 3 33. The fixing plate 3 31 is welded with a sleeve 36. The threaded rod 3 33 is welded in the sleeve 36 to increase the welding area. The fixing plate four 32 is fixed to the threaded rod three 33 by screws. The threaded rod three 33 is provided with a movable vertical baffle 34. The threaded rod three 33 is threadedly connected with a nut two 35. Two nuts two 35 are used on the single threaded rod three 33 to clamp and fix the baffle 34. The fixing structure one 29 is fixed to the baffle 34, and the fixing structure two 30 is fixed to the fixing plate four 32. The outer end of the chord rod 19 at the top is fixed by the fixing structure 1 29, and the fixing structure 1 29 is limited on the threaded rod 3 33 by the baffle plate 34, so as to limit the outer end of the upper chord rod 19, prevent the upper chord rod 19 from moving during welding, and ensure that the two upper chord rods 19 are arranged in parallel; the fixing structure 2 30 is used to fix the outer end of the chord rod 19 at the bottom, and the fixing structure 2 30 is fixed on the fixing plate 4 32, so as to prevent the lower chord rod 19 from moving during welding. When the inverted triangle truss is spliced, the upper chord rod 19 and the lower chord rod 19 are less affected by external forces during the welding process, thereby improving the splicing quality of the inverted triangle truss. Moreover, the installation position of the baffle plate 34 on the threaded rod 3 33 can be adjusted, and then the length of the upper chord rod 19 extending out of the assembly frame can be adjusted to meet the size requirements of the inverted triangle truss.

[0042] The fixing structure 29 includes two hoop plates 37, a connecting rod 39 and a fixing plate 5 44. The two hoop plates 37 are fixedly connected by bolts 49, so that the two hoop plates 37 clamp the outer end of the chord 19 at the top. The hoop plates 37 are fixed with a limiting plate 38. The connecting rod 39 is provided with a limiting groove 40. The limiting plate 38 is arranged in the limiting groove 40. The limiting plate 38 is threadedly connected to the limiting rod 42. The connecting rod 39 is provided with an adjustment hole 41. The adjustment hole 41 is connected to the limiting groove 40. The limiting rod 42 passes through the adjustment hole 41. The limiting rod 42 is threadedly connected with a nut 3 43. The nut 3 43 is tightened on the connecting rod 39. The fixing plate 5 44 is fixed to the connecting rod 39 by screws, and the fixing plate 5 44 is fixed to the baffle 34. When the chord rod 19 at the top of the present invention is tilted, the hoop plate 1 is also tilted, and the connecting rod 39 is also tilted at this time, and the connecting ends of the two connecting rods 39 cannot be aligned. In view of this technical problem, the present invention can rotate and move the connecting rod 39 on the limit rod 42. When the hoop plate 1 is tilted, the connecting rod 39 can be adjusted to a horizontal state, and the connecting ends of the two connecting rods 39 can be aligned, so that the connecting ends of the connecting rod 39 are used to install the fixing plate 5 44, and the screws between the fixing plate 5 44 and the connecting rod 39 are screwed in horizontally to avoid the situation where the screws are stuck. At the same time, the fixing plate 5 44 is in a vertical state, and the fixing plate 5 44 and the baffle 34 can be closely fixed, thereby increasing the firmness of the connection between the fixing plate 5 44 and the baffle 34, and facilitating the upper chord rod 19 to be transferred to the stable bracket 28 through the fixing structure 1 29 and the baffle 34. Moreover, the fixing of the fixing structure 1 29 and the baffle 34 can meet the requirement of limiting and fixing the chord rod 19 at a certain height at the top.

[0043] Since the chord 19 at the bottom is fixed at the bottom of the assembly frame, the fixing structure 2 30 is directly connected to the fixing plate 4 32. The present invention has a specific design for the fixing structure 2 30: the fixing structure 2 30 includes two hoop plates 2 45, and a tension bolt 46 is provided between the two hoop plates 2 45. The tension bolt 46 is provided with a nut 4 47, and the two hoop plates 2 45 are tightly clamped to the outer end of the chord 19 at the bottom. The hoop plates 2 45 are fixed with a threaded rod 4 48, and the threaded rod 4 48 passes through the fixing plate 4 32. The threaded rod 4 48 is threadedly connected with a nut 50, and a single threaded rod 4 48 is clamped and fixed to the fixing plate 4 32 by two nuts 50. The hoop plates 2 45 are fixed to the fixing plate 4 32 through the threaded rods 4 48, and the fixing method for the chord 19 at the bottom is simple.

[0044] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
