Description

Technical Field

[0001] This invention belongs to the field of curved floor decking foundation technology, and particularly relates to an adjustable large stadium irregular curved floor decking truss structure. Background Technology

[0002] The pressed steel sheets that support the concrete floor slabs are called profiled steel sheets, also known as floor decking or steel decking. These products are widely used in large venues such as power plants, power equipment companies, car showrooms, steel structure workshops, and cement warehouses. Large venues often have curved walls, making the installation of curved floor decking a crucial step in the process.

[0003] In the current technology, when installing curved floor decking for large venues, the entire curved wall is installed by first arranging an arc-shaped frame, and then installing an arc-shaped steel plate on the surface of the frame. The connection between the arc-shaped steel plate and the frame is weak, which limits the load-bearing capacity of the curved wall. Summary of the Invention

[0004] In light of the existing technology, when installing curved floor slabs in large venues, the entire curved wall installation involves first arranging an arc-shaped frame, and then installing arc-shaped steel plates on the surface of the frame. The connection between the arc-shaped steel plates and the frame is weak, resulting in limited load-bearing capacity of the curved wall. To address this technical problem, this invention proposes an adjustable truss structure for irregularly shaped curved floor slabs in large venues.

[0005] This invention proposes an adjustable large stadium irregular curved surface floor truss structure, which includes a curved steel plate. Multiple support components are arranged below the curved steel plate. Each support component includes a first column, a second column, and a top column. The first and second columns are rotatably connected at their middle sections by a rotating component. The top column is slidably connected to the first and second columns. The multiple support components are connected together by multiple steel pipes.

[0006] The upper ends of both the No. 1 and No. 2 pillars are connected to the curved steel plate via a connecting mechanism.

[0007] The upper parts of the No. 1 and No. 2 pillars are respectively rotatably connected to a first connecting shaft, and the lower parts of the two pillars are respectively rotatably connected to a second connecting shaft. The two first connecting shafts are horizontally overlapped, and the two second connecting shafts are horizontally overlapped.

[0008] A connecting sleeve is sleeved between the two first connecting shafts. An arc-shaped clamping plate is provided on one side of the connecting sleeve. The top column passes through the arc-shaped clamping plate. The arc-shaped clamping plate is fixedly clamped to the top column by a clamping mechanism. The connecting sleeve is fixedly connected to the two first connecting shafts by a clamping mechanism. The top end of the top column abuts against the curved steel plate.

[0009] Preferably, the curved steel plate has holes corresponding to the positions of the first and second support columns, and the connecting mechanism includes two annular sleeves spaced apart in the holes. The upper and lower ends of the two annular sleeves are connected by bolts and second nuts, respectively. The two bolts are located on the upper and lower surfaces of the curved steel plate, respectively. The upper ends of the first and second support columns are clamped between the corresponding two annular sleeves and connected to the bolts on that side.

[0010] Preferably, multiple slots are provided on both the left and right sides of one side surface of the top column, and the slots on the left and right sides are staggered. The locking mechanism is connected to the slots.

[0011] Preferably, the snap-fit ​​mechanism includes an insert block, with connecting blocks on both sides of one end of the insert block. The upper and lower sides of the arc-shaped snap plate are respectively provided with protruding mounting strips. An insertion port is opened on the arc-shaped snap plate between the two mounting strips. The insert block passes through the insertion port and snaps into the snap-fit ​​groove. A second threaded shaft is inserted between the two mounting strips. Both ends of the second threaded shaft are threaded with first nuts. The second threaded shaft passes through the connecting block, and the connecting block is snapped into the middle position of the second threaded shaft by a limiting block.

[0012] Preferably, the clamping mechanism includes two U-shaped clamps, which are respectively sleeved on two first connecting shafts. A first threaded shaft is threaded into one side of the connecting sleeve, and a wedge block is rotatably connected to the lower end of the first threaded shaft. The wedge block is clamped between the two U-shaped clamps.

[0013] Preferably, the side of the two U-shaped blocks that are close to each other is a slope and is narrower at the top and wider at the bottom. One side of the connecting sleeve is provided with a protrusion for threaded insertion of the first threaded shaft, and one side of the protrusion is provided with a limiting strip for limiting the two U-shaped blocks.

[0014] Preferably, the No. 1 and No. 2 pillars are provided with connecting holes, the steel pipe passes through the connecting holes, and multiple No. 1 pillars are connected together by the steel pipe, and multiple No. 2 pillars are also connected together by the steel pipe.

[0015] Preferably, a connecting frame is sleeved between the two second connecting shafts, and the top post passes through the connecting frame.

[0016] Compared with existing technologies, the advantages of the adjustable large-scale stadium irregular curved surface floor truss structure of the present invention are:

[0017] 1. By limiting the curvature of the curved steel plate through multiple support components, and then fixing the multiple support components together with steel pipes, the truss structure of the entire curved wall can be installed. The curvature of the curved steel plate depends on the position of the top column and the angle between the first and second columns. When the surface of the curved steel plate is subjected to external pressure, the first and second columns and the steel pipes share the pressure and can form a triangular structure with each other. The stability of the triangle also enables it to withstand greater pressure, making the overall structure more stable.

[0018] 2. After the installation of multiple support components with the curved steel plate is completed, the connection between the multiple support components is achieved through the No. 1 column. During the construction of the entire curved wall, the curvature of multiple curved steel plates is determined by the same method. Multiple curved steel plates can be directly fixed together with screws, and the curved floor deck of the entire large venue can be completed. This structure can adapt to curved walls with different curvatures, and the construction method is also very simple. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figures 1-6 An adjustable large stadium irregular curved surface floor truss structure includes a curved steel plate 1, and multiple support components are arranged below the curved steel plate 1. The support components include a first column 2, a second column 3 and a top column 5. The middle sections of the first column 2 and the second column 3 are rotatably connected together by a rotating component. The top column 5 is slidably connected to the first column 2 and the second column 3. The multiple support components are connected together by multiple steel pipes 4.

[0028] The upper ends of support column 2 and support column 3 are fixedly connected to curved steel plate 1 through a connecting mechanism; a first connecting shaft 11 is rotatably connected to the upper surface of support column 2 and support column 3 respectively, and a second connecting shaft 6 is rotatably connected to the lower surface of support column 2 and support column 3 respectively. The two first connecting shafts 11 are horizontally overlapped, and the two second connecting shafts 6 are also horizontally overlapped; a connecting sleeve 10 is sleeved between the two first connecting shafts 11, and an arc-shaped clamping plate 12 is provided on one side of the connecting sleeve 10. The top column 5 passes through the arc-shaped clamping plate 12, and the top end of the top column 5 abuts against the curved steel plate 1. The arc-shaped clamping plate 12 is fixedly clamped to the top column 5 through a clamping mechanism. The connecting sleeve 10 is fixedly connected to the two first connecting shafts 11 through a clamping mechanism.

[0029] In this embodiment, connecting holes are provided on the first support column 2 and the second support column 3. The steel pipe 4 passes through the connecting holes, and multiple first support columns 2 are connected together by the steel pipe 4. Multiple second support columns 3 are also connected together by the steel pipe 4. Under the curved steel plate 1, multiple support components are used to bend it into a predetermined arc structure. The multiple support components are then connected together by multiple first support columns 2 to form an integral structure. A connecting frame 7 is sleeved between the two second connecting shafts 6. The top column 5 passes through the connecting frame 7. The connecting frame 7 is used to limit the two second connecting shafts 6 located below.

[0030] In this embodiment, holes 8 are provided on the curved steel plate 1 corresponding to the positions of the first support column 2 and the second support column 3, respectively. The connecting mechanism includes two annular sleeves 21 spaced apart in the holes 8. The upper and lower ends of the two annular sleeves 21 are connected by bolts 22 and second nuts 23, respectively. The two bolts 22 are located on the upper and lower surfaces of the curved steel plate 1, respectively. The upper ends of the first support column 2 and the second support column 3 are respectively clamped between the corresponding two annular sleeves 21 and connected to the bolts 22 on that side. Hole 8 is made at the position where it connects to support column 2 or support column 3. Two annular sleeves 21 are passed through hole 8, so that the lower end of the annular sleeve 21 can clamp the upper end of support column 3 or support column 2. The annular sleeve 21 is fixedly connected to support column 2 or support column 3 by inserting bolt 22. Bolt 22 is also passed between the annular sleeves 21 located on the upper part of the curved steel plate 1, and the bolt 22 and the annular sleeve 21 are fixed by the second nut 23. Thus, the position of support column 3 or support column 2 and curved steel plate 1 is fixed by the connecting mechanism.

[0031] In this embodiment, multiple slots 9 are provided on both the left and right sides of one side surface of the top column 5, and the slots 9 on the left and right sides are staggered. The snap-fit ​​mechanism is connected to the slots 9. The staggered slots 9 compensate for the small gaps that cannot be covered between two adjacent slots 9. The snap-fit ​​mechanism includes a plug 17, and connecting blocks 13 are provided on both sides of one end of the plug 17. The upper and lower surfaces of the arc-shaped plate 12 are respectively provided with protruding mounting strips 16. The arc-shaped plate 12 has an insertion port. The plug 17 passes through the insertion port and snaps into the slot 9. A second threaded shaft 14 is inserted between the two mounting strips 16. The two ends of the second threaded shaft 14 are threaded with first nuts 15. The second threaded shaft 14 passes through the connecting block 13, and the connecting block 13 is snapped into the middle position of the second threaded shaft 14 by a limiting block.

[0032] When it is necessary to fix the position of the top column 5 relative to the first support column 2 and the second support column 3, the insert 17 is directly inserted into the corresponding slot, and then the second threaded shaft 14 is threaded through from one side, so that the second threaded shaft 14 is threaded through the mounting strips 16 on both sides. The second threaded shaft 14 passes through the side of the connecting block 13. A limiting block is set in the middle section of the second threaded shaft 14, so that the connecting block 13 can be snapped into the middle section of the second threaded shaft 14, and the position of the second threaded shaft 14 is fixed by the first nut 15. Then, the position of the top column 5 relative to the arc-shaped card plate 12 can be fixed by the insert 17. The slots 9 on both sides correspond to the connecting blocks 13 on both sides. The connecting block 13 on the side that is snapped into the slot 9 is fixed by the second threaded shaft 14 on that side.

[0033] In this embodiment, the clamping mechanism includes two U-shaped clamping blocks 20, which are respectively sleeved on two first connecting shafts 11. A first threaded shaft 18 is threaded into one side of the connecting sleeve 10. A wedge block 24 is rotatably connected to the lower end of the first threaded shaft 18. The wedge block 24 is clamped between the two U-shaped clamping blocks 20. When it is necessary to fix the relative position of the two first connecting shafts 11, the first threaded shaft 18 is rotated to drive the wedge block 24 to move downward. The wedge block 24 is narrow at the top and wide at the bottom. As the wedge block 24 moves, it can squeeze the U-shaped clamping blocks 20 to both sides. The relative position between the two first connecting shafts 11 is fixed by pressing. The side of the two U-shaped clamping blocks 20 that is close to each other is a slope 25 that is narrow at the top and wide at the bottom. A protrusion for threading the first threaded shaft 18 is provided on one side of the connecting sleeve 10. A limiting strip 19 for limiting the two U-shaped clamping blocks 20 is provided on the side of the protrusion.

[0034] In this embodiment, the curvature of the curved steel plate 1 is determined based on the curvature of the constructed curved wall. Three points can define a circle. The tops of the first support column 2, the second support column 3, and the top column 5 determine the curvature of the curved steel plate 1. The position of the rotational hinge point between the first support column 2 and the second support column 3 is determined. The tops of the first support column 2 and the second support column 3 are connected to the curved steel plate 1 through a connecting mechanism. The apex of the top column 5 abuts against the inner surface of the curved steel plate 1. The position of the top column 5 relative to the rotating component is adjustable. By adjusting the included angle between the first support column 2 and the second support column 3, the curvature of the curved steel plate 1 is determined through the first support column 2, the second support column 3, and the steel pipe 4. The farther the top column 5 is from the rotating component, the larger the arc of the curved steel plate 1. Changing the distance between the two first connecting shafts 11 The greater the distance between the two first connecting shafts 11, the larger the angle between the first support column 2 and the second support column 3, and the larger the arc of the curved steel plate 1 formed. Conversely, the smaller the arc of the curved steel plate 1 formed, the smaller the arc. The curvature of the curved steel plate 1 is limited by multiple support components, and the multiple support components are fixedly connected by steel pipes 4. Then the truss structure of the entire curved wall can be installed. The curvature of the curved steel plate 1 depends on the position of the top column 5 and the angle between the first support column 2 and the second support column 3. When the surface of the curved steel plate 1 is subjected to external pressure, the first support column 2, the second support column 3, and the steel pipe 4 distribute the pressure equally and can form a triangular structure with each other. The stability of the triangle also enables it to withstand greater pressure, making the overall structure more stable.

[0035] During installation, the tops of support column 2 and support column 3 are first connected to the curved steel plate 1. The annular sleeve 21 is passed through the two holes 8 so that the top of support column 3 or support column 2 is clamped in between. Bolt 22 is inserted between support column 3 and annular sleeve 21, and the two ends of bolt 22 are fixed with second nuts 23. Bolt 22 is also inserted into the annular sleeve 21 located on the upper surface of curved steel plate 1 and fixed with second nuts 23. The two bolts 22 abut against the surface of curved steel plate 1, thereby achieving the connection effect between support column 2, support column 3 and curved steel plate 1.

[0036] The included angle between support column 2 and support column 3 is then adjusted. Moving them closer to or further away from each other on the two first connecting shafts 11 changes the included angle between support column 2 and support column 3. The connecting sleeve 10 is simultaneously fitted onto the two first connecting shafts 11. Rotating the first threaded shaft 18 downwards moves the wedge block 24. The wedge block 24 is engaged between the two inclined surfaces 25. The wedge block 24 is wider at the top and narrower at the bottom, while the inclined surface 25 is narrower at the top and wider at the bottom. As the wedge block 24 moves, it can squeeze the inclined surface 25 to both sides, thereby making the inclined surface 25 tightly clamped with the first connecting shaft 11. The limiting strip 19 limits the inclined surface 25 to connect it with the connecting sleeve 10. Thus, the relative position between the connecting sleeve 10 and the first connecting shaft 11 can be fixed through the clamping mechanism.

[0037] Finally, the position of the top post 5 is adjusted so that the top of the top post 5 abuts against the lower surface of the curved steel plate 1, thereby strengthening the curvature of the curved steel plate 1. The insert block 17 is then snapped into the corresponding slot 9. The second threaded shaft 14 is threaded through one side of the mounting strip 16 and snapped into the connecting block 13. Rotating the second threaded shaft 14 can change its position relative to the mounting strip 16. By rotating the second threaded shaft 14, the insert block 17 can be finely adjusted, thereby finely adjusting the relative position of the top post 5. After determining the position, the end is fixed by aligning with 15.

[0038] After multiple support components are installed with the curved steel plate 1, the connection between the multiple support components is achieved through the No. 1 column 2. During the construction of the entire curved wall, the curvature of multiple curved steel plates 1 is determined by the same method. Multiple curved steel plates 1 can be directly fixed together with screws, and the curved floor deck of the entire large venue can be completed. This structure can adapt to curved walls with different curvatures, and the construction method is also very simple.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
