Description

Technical Field

[0001] This invention relates to the field of truss technology, and more specifically, to a modular space steel truss system and its synchronous jacking construction method. Background Technology

[0002] Steel trusses are trusses made of steel. Because steel trusses are mainly responsible for bearing radial tensile force or working pressure, they are suitable for stage setups. The application of stage trusses has become a common way of building stages in modern life.

[0003] In existing technologies, steel truss construction typically employs a high-altitude, in-situ assembly method. This involves installing multiple columns at intervals on the ground, then constructing temporary support platforms between these columns. Members and nodes are then assembled directly on these temporary platforms to form the steel truss mounted on the columns. After assembly, the temporary support platforms are dismantled to bring the structure to its designed state. After use, these temporary support platforms must be erected again for dismantling. This process is generally time-consuming and labor-intensive, requiring frequent high-altitude work by operators. In recent years, due to varying site requirements, the span requirements for steel trusses have become increasingly stringent. However, existing large-span steel trusses, due to their heavy weight and excessively long single spans, require high-altitude assembly. The conventional construction method involves erecting Bailey bridges and operating steel platforms, increasing the use of Bailey bridges and steel, thus increasing construction costs and time. Furthermore, the large span of the steel truss can affect its overall load-bearing stability. If the overall load-bearing stability of the steel truss is poor, the amount of equipment installed on it should be limited, otherwise, significant safety hazards may arise. Therefore, some existing traditional steel trusses suffer from high construction time and costs, and poor load-bearing stability when used as large-span steel trusses.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

Conversely, when dismantling the entire structure, the column structure can be dismantled step by step, so that the height of the truss and the equipment installed on it gradually decreases. Compared with the traditional assembly and dismantling process, this process does not require the assembly and disassembly of the truss and the installation and disassembly of the equipment on the truss to be completed at high altitudes, reducing the risk of high-altitude operations. At the same time, high-altitude operations will consume more time and energy due to factors such as narrow operating space. Therefore, the overall structure assembly process is safer, more convenient and saves more time than the traditional truss assembly process. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A modular space steel truss system, such as Figures 1-11As shown, the structure includes a truss body and several detachable column structures connected to the bottom of the truss body. The truss body provides stable support and restraint for lighting and audio equipment. Supported by the column structures, the truss body is stably lifted, ensuring it remains stable at a high position and fulfills its support and restraint functions. The column structures near the bottom contain lifting sections for gradually raising or lowering the truss body. These lifting sections allow the truss body and lighting equipment to be installed at a lower level during assembly. After assembly, the truss body gradually rises under the lifting action of the lifting sections. The column structure at the top of the jacking section is erected in stages, allowing the column structure to rise step by step, thereby raising the truss body step by step. Conversely, when dismantling the entire structure, the column structure can also be dismantled step by step, allowing the height of the truss body and the equipment installed on it to gradually decrease. Compared with the traditional assembly and dismantling process, this process eliminates the need to assemble and disassemble the truss body and install and dismantle the equipment on the truss body at high altitudes, reducing the risks of high-altitude operations. At the same time, high-altitude operations would consume more time and energy due to factors such as narrow operating space. Therefore, the overall structure construction process is safer, less labor-intensive, and saves more time than the traditional truss construction process. like Figures 1-4 As shown, a reinforced connection node 1 is provided at the connection between the truss body and the column structure. The frame body includes several main beam structures located at the reinforced connection node 1. Several secondary beam structures perpendicular to each other are detachably connected between the main beam structures. Several connecting beams 2 perpendicular to each other are detachably connected between two adjacent secondary beam structures. The high structural strength of the reinforced connection node 1 is used to stabilize and limit the position of the main beam structure, ensuring a more stable installation effect between the main beam structure and the column structure. Subsequently, it is ensured that the main beam structure can stably limit the position of the secondary beam structure, making the position of the secondary beam structure and its supporting and limiting functions more stable. The structural strength of the connecting beams 2 is used to stabilize and limit the position of the secondary beam structure while strengthening the overall structural strength. The main beam structure and the secondary beam structure stabilize and limit each other's positions, and the secondary beam structure and the connecting beams 2 stabilize and limit each other's positions, making the positions of the main beam structure, the secondary beam structure, and the connecting beams 2, as well as the subsequent positions, better in terms of load-bearing and wind resistance.

[0021] like Figure 1 and Figure 2As shown, the length direction of the main beam structure is consistent with the length direction of the truss body and is located between two adjacent main reinforcement connection points. The length direction of the secondary beam structure is consistent with the width direction of the truss body. The column structure includes two sets on both sides of the length direction of the truss body, and the length of the main beam structure between the two sets is greater than or equal to the length of the main beam structure in the same set. The truss body between the two sets of column structures is set as span zone 3. The column structures in the same set are symmetrical to each other, and the column structures on both sides of span zone 3 are symmetrical to each other with respect to span zone 3. This setting ensures that the distribution of the column structure is more uniform relative to the truss body, so that the multiple column structures can achieve a more uniform support and limiting effect on the truss body. At the same time, it makes the distribution of the lifting parts in the column structure more uniform relative to the truss body, so that the force application effect of multiple lifting parts on the truss body is more uniform, thereby enabling the lifting parts to better drive the truss body to rise and fall.

[0022] like Figures 2-6 As shown, the secondary beams at the reinforcing connection node 1 are arranged in pairs, close to each other. The secondary beams at the reinforcing connection nodes 1 on both sides of span zone 3 are arranged in pairs, close to each other and facing towards span zone 3. This arrangement allows the secondary beams and main beams to better strengthen the structure of span zone 3, resulting in better structural strength. This allows span zone 3 to meet the requirements of large spans while maintaining stable structural strength and support stability, thus better meeting the user's needs for large spans and improving the overall adaptability of the structure. The remaining secondary beams are arranged in groups, with each group distributed along an array. This arrangement ensures a more uniform distribution of the secondary beams within the truss, maximizing their structural strengthening effect on the truss. The main beam structures at the reinforced connection node 1 are arranged in two close proximity to each other. The reinforced connection node 1 effectively limits the position of the main beam structure, ensuring better positioning and support. Several vertical diagonal supports 4 are detachably connected between the two adjacent main beam structures. This arrangement makes the distribution of the multiple vertical diagonal supports 4 relative to the main beam structure more uniform, and makes the support and limiting functions applied by the multiple vertical diagonal supports 4 to the connected main beam structure more uniform. The vertical diagonal supports 4 are rod-shaped and made of steel. The vertical diagonal supports 4 are used to achieve stable limiting of the adjacent main beam structures, allowing the close main beam structures to limit each other, making the position of the main beam structure and the subsequent support effect more stable.

[0023] like Figures 2-4As shown, a first reinforcing zone 5 is formed between the main beam structure, the secondary beam structure, and the connecting beam 2 at the reinforcing connection node 1. Several intersecting first horizontal diagonal braces 6 are detachably connected to the secondary beam structure on the top and bottom sides of the first reinforcing zone 5. The first horizontal diagonal braces 6 are detachably connected to the secondary beam structure by means of retaining spring pins. The first horizontal diagonal braces 6 are strip-shaped and made of steel. Through holes are drilled on both sides of the length direction of the first horizontal diagonal braces 6 and on the secondary beam structure. The retaining spring pins are inserted into two concentrically arranged through holes on the first horizontal diagonal braces 6 and the secondary beam structure. Inside the hole, a detachable connection is achieved between the first horizontal tie rod 6 and the secondary beam structure. At the same time, the first horizontal tie rod 6 is used to stabilize and limit the positions of the secondary beam structure, main beam structure and connecting beam 2 in the first reinforcement zone 5. The first horizontal tie rods 6 in the same first reinforcement zone 5 are set to intersect each other, so that the two first horizontal tie rods 6 in the same first reinforcement zone 5 can stably resist the deformation process in two directions, ensuring that the first reinforcement zone 5 can better resist deformation when subjected to external forces, thereby ensuring better overall deformation resistance and support performance of the truss.

[0024] like Figures 2-4 As shown, a second reinforcing zone 7 is formed between the first secondary beam structure near the first reinforcing zone 5 and facing the span zone 3, its adjacent main beam structure, and the connecting beam 2. Second horizontal tie rods 8 are detachably connected to the secondary beam structures on the top and bottom sides of the second reinforcing zone 7. The second horizontal tie rods 8 are strip-shaped and made of steel, with through holes on both sides along their length. The secondary beam structure has through holes that are collinear with the through holes on the second horizontal tie rods 8. Snap pins are inserted into the through holes on the second horizontal tie rods 8 and the through holes on the secondary beam structure, enabling a detachable connection between the second horizontal tie rods 8 and the secondary beam structure. This allows the second horizontal tie rods 8 to provide support for the secondary beam structure located in the second reinforcing zone 7. The stability limiting of the secondary beam structure, main beam structure and connecting beam 2, and the second horizontal diagonal braces 8 in the same second reinforcement zone 7 are set as intersecting structures, so that the two second horizontal diagonal braces 8 in the same second reinforcement zone 7 can achieve stable resistance to deformation processes in two directions, ensuring that the second reinforcement zone 7 can better resist deformation when subjected to external forces, thereby ensuring better overall deformation resistance and support performance of the truss body. At the same time, it can also enhance the structural strength and support stability of the span zone 3, allowing users to increase the span of the span zone 3 according to their needs, so that the span zone 3 has a large span while also having good and stable structural strength and support strength, making the overall adaptability and stability of the structure better.

[0025] like Figures 3-6As shown, the main beam structure includes several main beams 9 that are detachably connected in sequence, and several first auxiliary connecting parts 10 located at the reinforcing connection node 1. Both the main beams 9 and the first auxiliary connecting parts 10 are made of steel and formed by welding. The secondary beam structure includes several secondary beams 11 that are detachably connected in sequence, and several second auxiliary connecting parts 12. Both the secondary beams 11 and the second auxiliary connecting parts 12 are made of steel and formed by welding. The main beams 9 are formed by cutting and welding square tubes, C-shaped steel, long strip steel plates, square steel plates and steel blocks. The main beams 9 are surrounded by several triangular... The secondary beam 11 is formed by cutting and welding C-shaped steel, steel plates, I-beams, square tubes and steel blocks. The secondary beam 11 is surrounded by several triangular grooves. The first auxiliary connector 10 is formed by cutting C-shaped steel, square tubes and steel plates and welding them. The first auxiliary connector 10 is surrounded by several triangular grooves. The good stability of the triangular structure is used to ensure better structural strength and support stability of the first auxiliary connector 10, the main beam 9 and the secondary beam 11. The second auxiliary connector 12 is formed by cutting C-shaped steel and steel bars and welding them.

[0026] like Figures 3-9As shown, several second auxiliary connectors 12 are located at the connection nodes between the secondary beam 11 and the first auxiliary connector 10, and between the secondary beam 11 and the main beam 9. The second auxiliary connectors 12 are used to assist in the installation between the secondary beam structure, the main beam structure, and the first auxiliary connector 10. A main beam base support 13 is detachably connected to the top of the column structure at the reinforced connection node 1. The main beam base support 13 is made by welding several hinge seats, C-shaped steel, and steel plates after cutting. The main beam base support 13 is used to stabilize and limit the connection between the connection structure and the first auxiliary connector 10, thereby strengthening the connection strength and stability between the column structure and the first auxiliary connector 10, thus forming the aforementioned reinforced connection node 1. The main beam base support 13 and the top of the column structure are connected by a retaining spring pin. The detachable connection is achieved by a shaft snap-fit ​​method. The first auxiliary connector 10 has several first sub-connectors 14 on one side in the horizontal direction, and several first female connectors 15 on the side of the first auxiliary connector 10 opposite to the first sub-connectors 14. The number of both the first sub-connectors 14 and the first female connectors 15 is set to four. The main beam 9 has several second female connectors 16 on one side in the length direction, which are interconnected with the first sub-connectors 14 via snap ring pins. The main beam 9 has several second sub-connectors 17 on the other side in the length direction, which are interconnected with the first female connectors 15 via snap ring pins. The number of both the second sub-connectors 17 and the second female connectors 16 is set to two. The first sub-connectors 14, first female connectors 15, second sub-connectors 17, and... The second female connector 16 has several through holes that are coaxial and identical in size after the main beam 9 and the second auxiliary connector 12 are spliced ​​together. These through holes are used for inserting the snap ring pin. After the main beam 9 and the first auxiliary connector 10 are spliced ​​together, the first male connector 14 and the second female connector 16 are spliced ​​together, and the first female connector 15 and the second male connector 17 are spliced ​​together. Adjacent main beams 9 are connected to each other by means of the second male connector 17, the second female connector 16, and the snap ring pin. After adjacent main beams 9 are spliced ​​together, the second male connector 17 and the second female connector 16 will be spliced ​​together. At the same time, the second male connector 17 and the second female connector 16 have through holes that are collinear and identical in size after splicing. The snap ring pin is inserted into the through holes to achieve the connection. For stable connections between adjacent main beams 9, a third sub-connector 18 is provided on one side of the second auxiliary connector 12 in the horizontal direction, and a third female connector 19 is provided on the other side of the second auxiliary connector 12 in the horizontal direction. On one side of the secondary beam 11 in the length direction, several fourth female connectors 20 are provided, interconnected with the third sub-connector 18 via snap ring pins. On the other side of the secondary beam 11 in the length direction, several fourth sub-connectors 21 are provided, interconnected with the third female connector 19 via snap ring pins. Adjacent secondary beams 11 are interconnected via fourth sub-connectors 21, fourth female connectors 20, and snap ring pins. The third sub-connector, third female connector, fourth sub-connector, and fourth female connector all have through holes that are collinear and of the same size after splicing. Snap ring pins are inserted into these through holes.This achieves a stable connection between the second auxiliary connector 12 and the secondary beam 11, and between the secondary beams 11 themselves; like Figures 3-9 As shown, several placement grooves 22 with the same width as the second auxiliary connector 12 are provided between two adjacent main beams 9 and between the main beam 9 and the first auxiliary connector 10. The placement grooves 22 are used to stabilize and limit the position of the second auxiliary connector 12 and the secondary beam structure as a whole, thereby strengthening the overall structural strength. Several fifth female connectors 23 are provided on both sides of the connecting beam 2 along its length. Several fifth female connectors 24 are provided on the end face of the secondary beam 11 and are connected to the fifth female connectors 23 by means of snap ring pins. The fifth female connectors 24 and the fifth female connectors 23 have through holes of the same size that are collinear after splicing. By inserting snap ring pins of suitable size into the through holes, a stable connection between the connecting beam 2 and the secondary beam 11 can be achieved. Several sixth female connectors 25 are provided on both sides of the vertical diagonal support 4 along its length. Several sixth female connectors 25 are provided on the main beam 9 and are connected to the sixth female connectors 25 by means of snap ring pins. The first head 26, the sixth sub-connector 25, and the sixth female connector 26 are provided with through holes of the same size that are collinear after splicing. By inserting the snap ring pin into the above-mentioned through holes, the connection between the vertical diagonal support 4 and the adjacent main beam 9 can be realized. This allows the vertical diagonal support 4 to achieve stable positioning of the relative position between the adjacent main beams 9. The truss body is divided into multiple main beams 9, secondary beams 11, connecting beams 2, first auxiliary connectors 10, second auxiliary connectors 12, first horizontal diagonal braces 6, second horizontal diagonal braces 8, vertical diagonal supports 4, etc., and spliced ​​by snap ring pins and through holes. This allows users to select the required number and type of parts for splicing according to their needs, making the overall structure more flexible to build and thus able to meet different user needs. This improves the overall applicability of the structure. At the same time, the use of snap ring pins for connection is more convenient and labor-saving than the traditional bolt connection method.

[0027] like Figures 2-8As shown, an extension area 27 is provided on one side of the truss body in the width direction. The extension area 27 is spliced ​​from the main beam 9, secondary beam 11, connecting beam 2, first horizontal diagonal tie rod 6 and second horizontal diagonal tie rod 8. The width of the extension area 27 is less than or equal to one-quarter of the width of the truss body. The extension area 27 is set to further widen the overall volume of the truss body. At the same time, setting the width of the extension area 27 to be less than or equal to one-quarter of the width of the truss body ensures that the extension area 27 can increase the overall volume of the truss body while avoiding excessive shift of the center of gravity of the truss body to the extension area 27, so as to improve the overall stability of the structure and allow for the installation of more lighting equipment and other devices on the truss body. Several arc-shaped tubes 28 are detachably connected to the truss body above the span area 3. The bottom of the arc-shaped tubes 28 is detachable. A number of first connecting pipes 29 are connected. The first connecting pipes 29 are vertically arranged and the side walls are fixedly connected to the connecting rods by welding. A square connecting pipe is sleeved on the connecting rod between two adjacent arc-shaped pipes 28. A square steel ring is fixedly connected to the first connecting pipe 29 below the connecting rod by welding. The square steel ring and the square connecting pipe are used to further limit the position of the square connecting pipe. The first connecting pipe 29 is a square pipe and a connecting steel plate is fixedly connected to it by bolts. A second connecting pipe 30 is fixedly connected to the secondary beam 11 for the bottom of the first connecting pipe 29 to pass through. The second connecting pipe 30 is a pipe body fixed to the secondary beam 11 by welding. The second connecting pipe 30 is vertically arranged and the first connecting pipe 29 is inserted vertically into the second connecting pipe 30.

[0028] like Figure 2 , Figure 9 , Figure 10 and Figure 11As shown, the column structure includes a base 31 for contacting the ground and several columns detachably connected to the base 31. The base 31 is formed by cutting and welding steel plates and square tubes. The columns are formed by cutting and welding hinge seats, directional tubes, and V-shaped rods. Several triangular grooves are formed around the columns, which improves the structural stability and support stability of the columns, thereby enhancing the overall support stability of the column structure. Several columns are sequentially spliced ​​vertically, and the columns are spliced ​​sequentially as the jacking unit is lifted, realizing the gradual increase in the overall height of the column structure. At the same time, during disassembly, the columns are disassembled one by one. The structure can be lowered step by step. The top of the base 31 is provided with a limiting groove 32 for the lifting part to be inserted. The limiting groove 32 is used to limit the lifting part placed inside, making the position of the top and the lifting function it can generate more stable. Several reinforcing extension rods 33 are detachably connected to the periphery of the base 31 by means of bolt locking. The reinforcing extension rods 33 can help increase the contact area between the base 31 and the support surface, so that the support stability of the base 31 and the column structure as a whole can be better, thereby ensuring that the overall structure is safer and more stable during use.

[0029] like Figure 2 , Figure 9 , Figure 10 and Figure 11As shown, several symmetrically arranged limiting hinge seats 34 are fixedly connected to the top surface of the base 31 near the limiting groove 32 by welding. A connecting hinge seat 35 is fixedly connected to the bottom of the main beam base 13 by welding. The column includes interlocking sub-connecting seats 36 and female connecting seats 37. The sub-connecting seats 36 and female connecting seats 37 can rotate around the limiting hinge seats 34 to interlock. When installing the sub-connecting seats 36 and female connecting seats 37, first connect the sub-connecting seats 36 and female connecting seats 37 to the connecting hinge seats 35 to achieve initial positioning of the sub-connecting seats 36 and female connecting seats 37 during installation. Then, rotate the sub-connecting seats 36 and female connecting seats 37 around their hinge points with the base 31 to complete the interlocking process. Several seventh sub-connecting heads 38 are provided at the connection point between the sub-connecting seats 36 and female connecting seats 37. The female connecting seat 37 is provided with a connection point between the seventh sub-connecting heads 38 and the seventh sub-connecting heads 38. A number of seventh female connectors 39 are connected by a snap ring pin. The seventh male connectors 38 and the seventh female connectors 39 have through holes on them, so that the central axes of the male connectors 36 and the female connectors 37 coincide after they are spliced. The snap ring pin is inserted into the through hole to restrict the relative position between the male connectors 36 and the female connectors 37. The bottom of the male connectors 36 and the female connectors 37 are fixedly connected by welding to a number of first hinge seats 40 that are hinged to the limiting hinge seat 34. The male connectors 36 and the female connectors 37 are connected to the main beam base support 13 by means of the limiting hinge seat 34, the first hinge seats 40 and the snap ring pin. The top of the male connectors 36 and the female connectors 37 are fixedly connected by welding to a number of second hinge seats 41. Adjacent columns are connected to each other by means of the first hinge seats 40, the second hinge seats 41 and the snap ring pin. The columns are connected to the main beam base support 13 by means of the second hinge seats 41 and the connecting hinge seats 35.

[0030] like Figure 2 , Figure 9 , Figure 10 and Figure 11As shown, the lifting unit includes a telescopic drive component 42 detachably connected to the base 31. The telescopic drive component 42 and the base 31 are detachably connected by bolts. The telescopic drive component 42 is equipped with a servo electric cylinder. The programmable nature of the servo electric cylinder allows the user to control the telescopic process of multiple telescopic drive components 42 through programming, enabling multiple lifting units to rise and fall synchronously. This ensures that multiple lifting units can work together to achieve a stable lifting function. The drive end of the telescopic drive component 42 is located on the bottom side and is fixedly connected to a connecting plate 43 detachably connected to the base 31. The connecting plate 43 is disc-shaped and made of steel. The connecting plate 43 is fixed to the drive shaft of the telescopic drive component 42 by welding. The connecting plate 43 has several circumferentially distributed through holes, and the base 31 has several threaded holes that are directly opposite the through holes. The detachable connection between the telescopic drive component 42 and the base 31 is achieved through the through holes, bolts, and threaded holes. Next, a lifting block 44 is rotatably connected to the outer wall near the driving end of the telescopic drive component 42. Four circumferentially distributed lifting plates 45 are fixedly connected to the lifting block 44 by welding. A circular steel plate that abuts against the bottom of the lifting block 44 is fixedly connected to the telescopic drive component 42 by welding or other means. A bearing is provided at the connection between the lifting block 44 and the telescopic drive component 42. The lifting plates 45 move with rotation to the bottom side of the column body or move out from directly below the column body. When the lifting plates 45 move... When the column reaches its solid position, the lifting plate 45 can be moved to apply force to the column. After the column at the bottom of the lifted column is installed, the lifting plate 45 can be manually moved to misalign with the solid part of the column. This allows the lifting plate 45 to pass over the column at the bottom, making it easier for the lifting plate 45 to continue to apply an upward lifting effect to the column at the bottom. This ensures that the column structure can be stably raised step by step.

S3 Connecting Beam 2: Construct the required truss structure and fix and install the required equipment to the truss structure; S4 span zone 3: Ensure that the lifting plate 45 of the lifting part abuts against the bottom surface of the main beam base support 13, remove the snap ring pin between the main beam base support 13 and the base 31, and drive several lifting parts to simultaneously push the truss body upward by at least the height of a column. S5 Vertical diagonal support 4: The sub-connector 36 and the female connector 37 are first hinged to the base 31 by a pin, so that the sub-connector 36 and the female connector 37 can rotate around the hinge point with the base 31 to splice with each other, and the sub-connector 36, the female connector 37 and the main beam base support 13 are connected by a snap ring pin. S6 First Reinforcement Zone 5: Remove the snap ring pin between the sub-connector 36 and the female connector 37 and the base 31, and use the lifting part to continue to lift the installed column and the structure on it upward. S7 First Horizontal Tie Rod 6: Install the new column and continue jacking until the entire structure reaches the required height.
