Description

Technical Field

[0001] The invention relates to the technical field of roof construction, in particular to a large-span steel structure roof of a port. Background Art

[0002] Traditional large-span steel structure ceilings are often used as part of port buildings. Large-span steel structure ceilings usually need to withstand wind force, which requires the ceiling structure to have sufficient strength and stability. In order to reduce the impact of wind force, steel structure ceilings are usually designed to be curved to reduce wind force. However, the curved truss has a large span and is still easy to deform after being stressed. Over a long period of time, it is easy to cause some parts to deform severely and require maintenance. And when the ceiling is affected by wind force, it will transfer the wind force to the supporting structure at the bottom, causing the supporting structure at the bottom of the ceiling to be unstable due to lateral force. Although the supporting structure at the bottom of the ceiling is usually equipped with a diagonal brace structure to reduce the damage and deformation of the supporting structure, the connection between the ceiling and the supporting structure is still prone to damage and deformation.

[0040] Please refer to Figure 1 and Figure 2 A large-span steel structure ceiling for a port in a preferred embodiment of the present invention includes an arc truss 100, an end rod 200, a reinforcing cross bar 300, a steel rope connection assembly 400, a ground anchor assembly 500 and a first steel wire rope 600.

[0041] The arc truss 100 generally includes an upper arc chord and a lower arc chord, and a connecting rod is provided between the upper arc chord and the lower arc chord. The end rods 200 are arranged symmetrically and connected to the left and right sides of the arc truss 100 respectively. The bottom of the end rods 200 protrudes out of the arc truss 100 to facilitate the connection of the reinforcing cross rod 300. The end rods 200 can be connected and fixed to the arc truss 100 by welding or fasteners.

[0042] The left and right ends of the reinforcing cross bar 300 are respectively connected to the bottoms of the two end bars 200 on the left and right sides. The steel rope connection assembly 400 is arranged symmetrically, and the symmetrical steel rope connection assembly 400 is respectively connected to the bottoms of the two end bars 200 on the left and right sides.

[0043] The ground anchor assembly 500 is pre-buried in the ground and is symmetrically arranged on the left and right sides of the arc truss 100, specifically located below the left and right sides of the arc truss 100, with a certain distance from the arc truss 100 in both the left and right directions and the height direction. A rope connection structure 510 protruding from the ground is provided at the upper end of the ground anchor assembly 500.

[0044] One end of the first steel wire rope 600 is connected to the steel wire rope connection assembly 400 on the corresponding side, and the other end is connected to the ground anchor assembly 500 on the corresponding side.

[0045] In a preferred embodiment of the present invention, a large-span steel structure roof of a port is provided. By setting the end rods 200 and the reinforcing cross rods 300, the design strengthens the lateral support of the arc truss 100, reduces the lateral deformation caused by wind force, and improves the overall stability of the roof; the steel rope connection assembly 400 and the first steel wire rope 600 are provided to effectively transfer the wind load of the arc truss 100 to the ground anchor assembly 500, so that the wind load of the roof is directly transferred to the ground, dispersing the influence of wind force on the roof, and reducing the impact on the bottom support structure (such as Figure 1 The lateral force influence of the support column 900 shown in the figure enhances the stability of the support structure (support column 900), reduces the risk of damage, reduces the vibration and deformation of the ceiling caused by wind, and reduces the deformation or even damage of the connection between the ceiling and the bottom support structure (support column 900).

[0046] Reference Figure 1 In some embodiments of the present invention, a second steel wire rope 800 is further included, and both ends of the second steel wire rope 800 are respectively connected to the left-right symmetrical steel wire rope connection components 400, that is, the left end of the second steel wire rope 800 is connected to the steel wire rope connection component 400 corresponding to the left side, and the right end of the second steel wire rope 800 is connected to the steel wire rope connection component 400 corresponding to the right side, thereby connecting the steel wire rope connection components 400 on the left and right sides in series, so that the first steel wire rope 600 on the left side can act on the right side of the arc truss 100, and the first steel wire rope 600 on the right side can act on the left side of the arc truss 100, thereby increasing the action range of the first steel wire rope 600, forming a closed-loop tensioning structure, reducing the force on the left and right sides of the arc truss 100 transmitted through its own structure and the reinforcing cross bar 300, reducing the force on the arc truss 100 and the reinforcing cross bar 300, and reducing the arc truss 100 and The reinforcing cross bar 300 are subjected to stress. The rod 300 is deformed, so that most of the force is directly transmitted to the ground through the first steel wire rope 600 and the second steel wire rope 800. For example, when the right side of the arc truss 100 is subjected to a force to the right, generally, the force on the right side of the arc truss 100 will be transmitted to the left side through its own structure and the reinforcing cross bar 300, and the force will be transmitted to the ground through the first steel wire rope 600 and the steel wire connecting assembly 400 on the left. With the series effect of the second steel wire rope 800, at least part of the force on the right side of the arc truss 100 will be directly transmitted to the first steel wire rope 600 and the steel wire connecting assembly 400 on the left through the second steel wire rope 800, and finally transmitted to the ground, thereby reducing the force inside the arc truss 100 itself and the reinforcing cross bar 300, reducing the load and deformation of the arc truss 100 and the reinforcing cross bar 300, and improving the structural stability and life.

[0047] Reference Figure 2 , Figure 3 and Figure 4In a further embodiment of the present invention, a first connection hole 210 is provided at the bottom of the end rod 200, and the first connection hole 210 is provided at the portion of the bottom of the end rod 200 protruding from the arc truss 100. A groove 310 is provided in the reinforcing cross bar 300, and a second connection hole 311 corresponding to the first connection hole 210 is provided on the end wall of the groove 310. The first connection hole 210 and the second connection hole 311 are aligned and penetrated with a bolt 700, and one end of the bolt 700 passes through the second connection hole 311 and is connected with a nut 710, and the bolt 700 and the nut 710 are used to realize the connection between the end rod 200 and the reinforcing cross bar 300.

[0048] Reference Figures 2 to 4In a further embodiment of the present invention, a through hole 720 is provided at the center of the bolt 700; the steel rope connection assembly 400 includes a first docking rod 410 and a second docking rod 420, one end of the first docking rod 410 is inserted into the through hole 720 and can rotate and move left and right in the through hole 720, and the other end is located outside the through hole 720 and is provided with a first rod head 411 with a diameter larger than the through hole 720, and the outer end surface of the first rod head 411 is provided with a first rope ring 412. One end of the second docking rod 420 is inserted into the through hole 720 and can rotate and move left and right in the through hole 720. The other end is located outside the through hole 720 and is provided with a second rod head 421 with a diameter larger than the through hole 720. The outer end surface of the second rod head 421 is provided with a second rope ring 422. The end of the second docking rod 420 inserted into the through hole 720 is connected to the end of the first docking rod 410 inserted into the through hole 720. One end of the first steel wire rope 600 is connected to the first rope ring 412. The second steel wire rope 800 is buried in the groove 310. The two ends of the second steel wire rope 800 are respectively connected to the second rope rings 422 on the left and right sides. It can be understood that the diameters of the first docking rod 410 and the second docking rod 420 are adapted to the through hole 720 and are clearance fit. The first docking rod 410 and the second docking rod 420 can both move in the through-hole 720, so that the second steel wire rope 800 and the first steel wire rope 600 can achieve force transmission through the first docking rod 410 and the second docking rod 420. If the first docking rod 410 and the second docking rod 420 cannot move in the through-hole 720, the force of the first steel wire rope 600 can only be transmitted to the first docking rod 410, the bolt 700, the end rod 200 and the arc truss 100 in sequence, and the force of the first steel wire rope 600 will not be transmitted to the second steel wire rope 800 through the first docking rod 410 and the second docking rod 420. The second docking rod 420 is connected to the first docking rod 410 as a whole, and because the diameters of the first rod head 411 and the second rod head 421 are larger than the through hole 720, the left and right movements of the second docking rod 420 and the first docking rod 410 are restricted and will not separate from the through hole 720, and the first rod head 411 and the second rod head 421 are respectively provided with a first rope ring 412 and a second rope ring 422 to be connected to the first steel wire rope 600 and the second steel wire rope 800 respectively. In addition, the force acting on the arc truss 100 is transmitted to the first rod head 411 or the second rod head 421 through the bolt 700, and finally transmitted to the ground anchor assembly 500 on the ground through the first steel wire rope 600 and the second steel wire rope 800. The first docking rod 410 and the second docking rod 420 are integrated into the center of the bolt 700, making the structure more compact. There is no need to make additional holes on the end rod 200 and the reinforcing cross bar 300, and the cross-sectional dimensions of the end rod 200 and the reinforcing cross bar 300 are not increased due to the need for multiple holes.It is understandable that in order to achieve an effective force transmission path, the first rod head 411 and the second rod head 421 will not clamp the bolt 700. Under normal conditions without external force, the first rod head 411 and the second rod head 421 will not generate direct force with the end of the bolt 700.

[0049] It is understandable that if Figure 2 As shown, in a specific embodiment of the present invention, a first rope hook 610 may be provided at the end of the first steel wire rope 600 to hook the first rope ring 412 , and a second rope hook 810 may be provided at the end of the second steel wire rope 800 to hook the second rope ring 422 .

[0050] Reference Figure 4 In a further embodiment of the present invention, one end of the first docking rod 410 inserted into the through hole 720 is provided with a first threaded hole 413, and one end of the second docking rod 420 inserted into the through hole 720 is provided with a threaded column 423 threadedly connected to the first threaded hole 413; the threaded column 423 is threadedly connected to the first threaded hole 413 to achieve a detachable connection between the first docking rod 410 and the second docking rod 420, thereby facilitating the connection, and both the first docking rod 410 and the second docking rod 420 can rotate and move in the through hole 720, and are not affected during connection, and due to the design of the first docking rod 410 and the second docking rod 420, during installation, they are not affected by the inability of the first rod head 411 and the second rod head 421 to enter the through hole 720.

[0051] Reference Figure 5 In a further embodiment of the present invention, the ground anchor assembly 500 includes a pre-embedded plug-in 520, a lifting and adjusting member 530 and a rotating movable member 540. The pre-embedded plug-in 520 is used to be inserted into the ground. The lifting and adjusting member 530 is connected to the pre-embedded plug-in 520 and can be lifted and lowered relative to the pre-embedded plug-in 520 to adjust the position. After the connection and installation, the position of the rope connection structure 510 can be lifted and lowered, so that the first steel wire rope 600 is in a tensioned state, so that it can play a role in tensioning and stabilizing the arc truss 100. The rotating movable member 540 is installed on the lifting and adjusting member 530 and can rotate and move along the axis of the lifting and adjusting member 530, so that it can rotate freely to adjust the position, so that it can adapt to the hooking of the first steel wire rope 600. The rope connection structure 510 is connected to the rotating movable member 540. The rope connection structure 510 is specifically a ring-shaped structure, having a hook hole for the first rope hook 610 to hook.

[0052] Reference Figure 5In some embodiments of the present invention, the embedded plug 520 includes a column 521, and a pointed cone head 522 is provided at the bottom of the column 521, the pointed cone of the pointed cone head 522 is facing downward, and the top edge profile of the pointed cone head 522 is larger than the column 521. When installed, it can be easily inserted into uncured concrete, and after the concrete is solidified, since the top edge profile of the pointed cone head 522 is larger than the column 521, the column 521 will not be easily pulled out, and the effect of stable anchoring is achieved. The upper edge of the column 521 is provided with a limiting skirt 523 extending horizontally outward, so that when inserted into the uncured concrete, the limiting skirt 523 can fit with the upper surface of the concrete to limit the insertion depth of the column 521. A second threaded hole 524 is provided at the center of the upper end surface of the column 521, and the lifting and lowering adjusting member 530 is threadedly connected to the second threaded hole 524 to achieve lifting and lowering adjustment; the lifting and lowering adjusting member 530 is provided with an embedding groove 531 with a bottom opening, and a protruding opening 532 is provided at the top of the embedding groove 531, and the outline of the protruding opening 532 is smaller than the embedding groove 531; the rotating movable member 540 includes a rotating limit head 541 located in the embedding groove 531 and capable of rotating and moving relative to the lifting and lowering adjusting member 530 in the embedding groove 531, and the outline of the rotating limit head 541 is larger than the protruding opening 532, so that the rotating limit head 541 cannot be separated from the protruding opening 532, so that the rotating limit head 541 is restricted in the embedding groove 531 to achieve vertical limiting. The outline of the rotating limit head 541 is larger than the protruding opening 532; an extension column 542 passing through the protruding opening 532 is provided at the upper end of the rotating limit head 541, and the rope connection structure 510 is connected to the upper end of the extension column 542. The lifting and lowering adjustment of the rope connecting structure 510 can be achieved by rotating the lifting and lowering adjusting member 530, and because the rotating movable member 540 can rotate relative to the lifting and lowering adjusting member 530, when the lifting and lowering adjusting member 530 is rotated, the rotating movable member 540 can rotate relative to the lifting and lowering adjusting member 530, so that the rotating movable member 540 does not rotate with the lifting and lowering adjusting member 530, thereby preventing the rotating movable member 540 from rotating and causing the rope connecting structure 510 and the first steel wire rope 600 on the rope connecting structure 510 to twist, thereby causing resistance to the rotation of the lifting and lowering adjusting member 530 and avoiding excessive twisting and damage of the first steel wire rope 600.

[0054] Reference Figure 1 and Figure 6In a further embodiment of the present invention, the upper ends of all the end rods 200 on the same side are connected by a first serial rod 220, thereby connecting the front and rear end rods 200 in series. The front and rear adjacent reinforcing cross bars 300 are connected by a second serial rod 320, thereby connecting the reinforcing cross bars 300 in series. The reinforcing cross bars 300 are connected to vertical rods 330, and the upper ends of the vertical rods 330 are connected to the corresponding arc trusses 100, thereby providing multi-point support for the arc trusses 100. In addition, as Figure 6 As shown, the front and rear adjacent arc trusses 100 can be connected in series through the third series rod 110. The first series rod 220, the second series rod 320 and the third series rod 110 are used to connect the front and rear spaced structures in series to form a stable overall steel frame structure, thereby improving the stability of the overall structure.

That is, one end of the oblique rod 230 is connected to the upper end of one of the two adjacent end rods 200, and the other end is connected to the lower end of the other of the two adjacent end rods 200. Thus, the two adjacent end rods 200 are connected in series, and the end rods 200 are braced diagonally. The oblique rod 230, the first series rod 220 and the end rods 200 form a triangular structure, which is more stable.
