Description

Technical Field

[0001] This invention relates to the field of steel structure building technology, specifically to large-span steel structure roofs. Background Technology

[0002] In traditional construction, ensuring the columns are absolutely vertical is the foundation for installing the upper beams and trusses. However, during concrete foundation construction, the position and elevation of anchor bolts or anchor plates inevitably have construction errors at the millimeter or even centimeter level. Simply stuffing steel plates of different thicknesses between the column base and the foundation to fill the error cannot achieve continuous and subtle angle correction, which affects the installation of the subsequent structure of the shed.

[0003] Therefore, a large-span steel structure roof was proposed to address the above issues. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 7 As shown, the large-span steel structure roof includes a column 1 and a support mechanism 5 integrated at its lower end. The support mechanism 5 includes a side bracing assembly set on the side of the column 1 and a main support plate 59 set directly below the column 1.

[0020] The side bracing assembly includes a side bracing plate 51 and a diagonal brace 52. Both ends of the diagonal brace 52 are movably connected to the side bracing plate 51 and the column 1, respectively. The diagonal brace 52 is slidably connected to the guide rail 54 via a single-sided slider 53, and its two ends are rotatably connected via bearings, enabling stepless and flexible adjustment of its height and support angle. This allows the diagonal brace 52 to accurately align with the pre-set ground threaded anchor rod, greatly reducing the difficulty of on-site drilling or modification, and demonstrating strong adaptability. Once the position of the diagonal brace 52 is determined, the side bracing plate 51 is mechanically locked to the ground anchor rod via a nut, and the guide rail 54 is clamped by tightening the fastening screw 513, forming a friction lock. This dual locking mechanism ensures the absolute stability of the lateral support under complex loads, preventing slippage or loosening.

[0021] The main support plate 59 is fixed to the ground and movably connected to the lower end of the column 1. The column 1 is equipped with a leveling device that acts on the main support plate 59. The ball joint connection formed by the male ball joint 518 and the female ball joint 517 allows the column 1 to obtain a multi-degree-of-freedom swing foundation. With the leveling screws 58 that can rotate independently in four directions pressing the main support plate 59, the column 1 can be finely and precisely adjusted in angle, effectively compensating for uneven foundation or installation errors, ensuring the verticality of the column 1, and thus laying a precise horizontal benchmark for the installation of the upper beam 2 and the arc truss 3.

[0022] Detailed implementation process and principle explanation: A support mechanism 5 is integrated at the lower end of the column 1. The support mechanism 5 can be divided into two parts with the side support plate 51 and the main support plate 59 as the center. The side support plate 51 is located on the side of the column 1 and works with the diagonal brace 52 to provide diagonal support for the column 1. The main support plate 59 is set directly below the column 1 to adjust the verticality of the column 1, thereby ensuring the horizontality of the crossbeam 2 installed at the upper end of the column 1. Similarly, when installing the arc truss 3, the horizontality of the arc truss 3 can be ensured. Finally, the roof panel 4 is set on the top surface of the arc truss 3 to complete the installation of the entire steel structure roof.

[0023] Example 1: like Figure 6 and Figure 7As shown, a ball joint male seat 518 is fixed on the upper surface of the main support plate 59, and a ball joint female seat 517 that movably engages with the ball joint male seat 518 is fixed on the lower end face of the column 1. This releases the rotational constraint between the column 1 and the foundation, allowing the column 1 to swing freely at a small angle in three-dimensional space for leveling. The leveling device includes a cross plate 57 fixed to the surface of the column 1 and a leveling screw 58 threaded onto the cross plate 57. The lower end of the leveling screw 58 can abut against the upper surface of the main support plate 59. The operator can precisely lift or loosen a certain side of the column 1 by rotating the leveling screw 58 in different positions, thereby accurately controlling its verticality. Compared with the traditional shim leveling, this method has higher precision, more controllable operation, and quantifiable process, i.e., the number of rotations corresponds to the adjustment amount.

[0024] The main support plate 59 has a strip-shaped notch 519 with an opening design on its side. With the help of the ground threaded anchor rod and nut, the main support plate 59 is firmly installed. The ball head male seat 518 is fixed at the center of the upper surface of the main support plate 59, and the ball head female seat 517 is fixed at the center of the lower end face of the column 1. The ball head male seat 518 and the ball head female seat 517 are movably connected. Four leveling screws 58 are threadedly connected to the cross plate 57 fixed on the surface of the column 1. By rotating the leveling screws 58 in different positions, the angle of the column 1 can be adjusted to ensure the verticality of the entire column 1.

[0025] When connecting to the pre-embedded threaded anchor rods in the ground, the strip-shaped notch 519 of the main support plate 59 allows for fine-tuning of the position of the main support plate 59 within a certain range to align with the anchor rods; this effectively compensates for the construction errors of the foundation pre-embedded parts, greatly reduces the probability of on-site hole enlargement or rework, and improves installation efficiency.

[0026] In one specific embodiment, a rubber pressure relief block 522 is provided at the lower end of the leveling screw 58.

[0027] Specifically, the rubber pressure relief block 522 at the lower end of the leveling screw 58 contacts the main support plate 59, providing a flexible pressure buffer and distribution interface between the leveling screw 58 and the main support plate 59. This prevents the hard end of the leveling screw 58 from causing point contact crushing or scratches on the surface of the main support plate 59, ensuring uniform pressure transmission and avoiding damage to the main support plate 59 due to uneven force.

[0028] Example 2: like Figure 2 and Figure 4As shown, a vertically arranged guide rail 54 is fixed on the surface of the column 1. The side support assembly also includes a single-sided slider 53 that is slidably connected to the guide rail 54. The upper end of the diagonal brace 52 is rotatably connected to the single-sided slider 53. The single-sided slider 53 is provided with a locking mechanism, which includes a buckle plate 512 and a fastening screw 513. Tightening the fastening screw 513 can drive the buckle plate 512 and the single-sided slider 53 to clamp the guide rail 54 together. Once the diagonal brace 52 is adjusted into place and fastened to the ground anchor bolt, tightening the fastening screw 513 can make the buckle plate 512 and the single-sided slider 53 form a clamp, firmly holding the guide rail 54. This locking method does not damage the surface of the guide rail 54, is easy to unlock, and can provide huge static friction force to ensure that the lateral support system will not slip or loosen under the action of reciprocating forces such as wind load. The upper and lower ends of the guide rail 54 are respectively fixed with an upper stop block 55 and a lower stop block 516.

[0029] The upper stop 55 and the lower stop 516 define the physical limits of the movement of the entire side support assembly, preventing the slider from dislodging from the guide rail 54 during adjustment or accidental events. They are important safety limit devices that ensure the integrity of the mechanism during transportation, hoisting and adjustment.

[0030] A guide rail 54 is fixedly connected to the surface of column 1 via an upper stop block 55. A lower stop block 516 is fixed to the lower end of the guide rail 54. The side support plate 51 is rotatably connected to the shaft 523 at the end of the diagonal support rod 52 via the first bearing 510 on its surface. The shaft 523 at the upper end of the diagonal support rod 52 is rotatably connected to the second bearing 511 fixed to the side of the single-sided slider 53. The single-sided slider 53 is slidably connected to the guide rail 54. Therefore, the position of the side support plate 51 and the angle of the diagonal support rod 52 can be adjusted flexibly and synchronously to align the threaded hole 520 of the diagonal support rod 52 with the ground threaded anchor rod on the side of column 1. Then, the nut is tightened and the fastening screw 513 is tightened. The buckle plate 512 is pressed and slides towards the guide rail 54. The buckle plate 512 cooperates with the edge of the single-sided slider 53. After the fastening screw 513 is tightened, the guide rail 54 can be tightly clamped by the buckle plate 512 to restrict the sliding of the single-sided slider 53. At this time, the state of the diagonal support rod 52 is locked.

[0031] Example 3: like Figure 3 and Figure 5 As shown, it also includes a central slider 56 that slides along the guide rail 54. The central slider 56 is located below the single-sided slider 53. The side of the central slider 56 is provided with a clamping plate 515. When the single-sided slider 53 slides to a position close to the upper stop block 55, the diagonal brace 52 can be inserted into the clamping plate 515. The clamping plate 515 is provided with a main insertion hole 521, and the diagonal brace 52 is provided with a secondary insertion hole 514. When the diagonal brace 52 is inserted into the clamping plate 515, the main insertion hole 521 and the secondary insertion hole 514 are aligned.

[0032] Through the designed central slider 56, clamping plate 515 and pin hole structure, all the diagonal bracing rods 52 can slide upwards and retract synchronously, tightly fitting against the main body of column 1.

[0033] A central slider 56 is slidably mounted on the outer surface of the column 1. The central slider 56 can slide synchronously along the guide rail 54. When the column 1 is in an idle transport state, pushing the central slider 56 upward will simultaneously push the single-sided slider 53 to slide upward together until the single-sided slider 53 contacts the upper stop block 55 of the guide rail 54. Under the action of the gravity of the diagonal brace 52 itself, during the sliding process, the diagonal brace 52 will gradually be inserted into the clamping plate 515 on the side of the central slider 56 until the main insertion hole 521 of the clamping plate 515 and the secondary insertion hole 514 of the diagonal brace 52 are aligned. Then, the pins are passed through the main insertion hole 521 and the secondary insertion hole 514 in sequence to keep each diagonal brace 52 in a closed state that fits against the column 1 for easy transport.

[0034] Once all the diagonal braces 52 are retracted and fitted into the column 1, the pins pass through the aligned main insertion holes 521 and auxiliary insertion holes 514, which can securely lock the entire assembly in a compact state. This minimizes the external dimensions during transportation and stacking, and prevents the column 1 from shaking, colliding, deforming, or snagging on other objects during transportation. It protects the component and improves transportation safety and loading efficiency, making it particularly suitable for long-distance transportation of the column 1.

[0035] like Figures 8 to 10 As shown, Example 5: Tenon 6 is set at the connection point between the beam 2 and the column 1. The top of the column 1 is also provided with mortise 7 that matches the tenon 6. Therefore, during the hoisting process of the beam 2, the beam 2 and the column 1 can be temporarily connected by splicing the tenon 6 and the mortise 7. At the same time, after the tenon 6 and the mortise 7 are spliced, it can also ensure that the center of the beam 2 and the column 1 are aligned.

[0036] In one specific embodiment, a detachable positioning mechanism 8 is provided at the top of the column 1 to achieve a rapid positioning effect for the tenon 6 and the mortise 7. The positioning mechanism 8 consists of a main frame 81 and a secondary frame 82. Guide inclined plates 88 are provided on the inner walls of both the main frame 81 and the secondary frame 82. After the main frame 81 and the secondary frame 82 are spliced ​​and fixed at the top of the column 1, the guide inclined plates 88 inside the main frame 81 and the secondary frame 82 form a square guide with the cone facing downward. Therefore, the tenon 6 of the crossbeam 2 can slide along the square guide to the mortise 7 at the center point of the top of the column 1, achieving rapid positioning and splicing. The lower end of the tenon 6 is inserted into the mortise 7. Afterwards, loosen the locking nut 87 at the end of the movable screw 86, leaving sufficient clearance between the locking nut 87 and the positioning seat 83 on the side of the sub-frame 82. At this time, the movable screw 86 can be rotated by utilizing the rotational connection between the round shaft 85 at the tail end of the movable screw 86 and the connecting seat 84 on the side of the main frame 81. The main frame 81 and the sub-frame 82 can then be removed from the top of the column 1. At the same time, when the main frame 81 and the sub-frame 82 are assembled, the movable screw 86 is rotated back, so that the movable screw 86 is engaged with the notch of the positioning seat 83. Finally, tighten the locking nut 87 to fix the assembled main frame 81 and sub-frame 82 to the top of the column 1.

[0037] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
