Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and specifically to a support system for the construction of cast-in-place concrete pipe racks. Background Technology

[0002] In the construction of chemical industrial parks, municipal engineering projects, and other fields, cast-in-place concrete pipe racks are a common structural form. These pipe racks typically feature large spans and heavy loads, placing high demands on the stability, load-bearing capacity, and construction efficiency of their underlying support system. Traditional support methods often employ steel pipe scaffolding to erect full-span supports or large standardized steel frames. Full-span supports involve a large workload for erection and dismantling, consume a lot of materials, and have poor site adaptability; large standardized steel frames lack flexibility and have high transportation and hoisting costs. Furthermore, some existing support devices need improved stability when dealing with lateral forces (such as pouring impact and wind loads), and the process of finely adjusting the vertical height is cumbersome, making it difficult to simultaneously guarantee safety, accuracy, economy, and convenience. Therefore, a modular support solution that combines high stability, convenient adjustability, and good economy is needed. Utility Model Content

[0003] In view of this, the present invention provides a modular support system for cast-in-place concrete pipe racks, aiming to overcome some shortcomings of traditional support methods in terms of efficiency, stability, and economy. This system, through modular design, combines a reliable lifting mechanism with a highly efficient lateral stabilizing structure to provide a support solution with high load-bearing capacity, high stability, and easy and quick assembly and disassembly.

[0004] The objective of this utility model is achieved through the following technical solution: A modular support system for cast-in-place concrete pipe racks includes a top support beam and at least two support units spaced apart along the length of the top support beam. Each support unit includes a jacking support system, a central jacking system, and a lateral stabilization system. The jacking support system includes a top support hinged seat fixed to the bottom of the top support beam. The central jacking system includes a main upright and a jack disposed between the top support hinged seat and the top of the main upright, with the base of the jack fixedly connected to the top of the main upright. The lateral stabilization system includes at least one fixed-length diagonal brace. The upper end of the fixed-length diagonal brace is connected to the upper part of the main upright via a first universal joint, and its lower end is hinged to an anchor point on the ground via a second universal joint.

[0005] This system employs a modular design to create a highly efficient and stable support system. Jacks provide powerful and reliable vertical lifting force. The top support beam and hinged joints effectively distribute the load. The lateral stabilization system, through fixed-length diagonal braces and the main uprights forming a triangular stability structure, significantly enhances resistance to lateral displacement. Universal joints ensure that the diagonal braces only bear tensile and compressive forces, simplifying the stress distribution. The modular design allows for flexible system combinations to adapt to different span requirements, facilitating transportation and rapid assembly / disassembly, thus improving construction efficiency and safety.

[0006] It should be noted that the "universal joint" mentioned in this utility model refers to a hinged device capable of rotation in multiple directions, including but not limited to ball joints, cross-axis universal joints, and other connection forms that enable multi-dimensional rotation. These joint forms ensure that the fixed-length diagonal brace mainly bears axial tensile and compressive forces during operation, avoiding the generation of bending moments.

[0007] Preferably, the jack is a screw jack or a hydraulic jack.

[0008] Two mature and reliable lifting options are provided. The screw jack features mechanical self-locking capability, precise positioning, and easy maintenance. The hydraulic jack offers high lifting capacity, effortless operation, and stepless adjustment. Both are commonly used standard parts, facilitating procurement and replacement, allowing users to flexibly choose according to specific working conditions and budget.

[0009] Preferably, a horizontal scissor brace connects the main uprights of two adjacent support units.

[0010] Horizontal scissor bracing connects independent support units into a unified spatial frame, significantly improving the overall rigidity and resistance to horizontal loads of the system. It effectively suppresses lateral swaying and instability of the main uprights, ensures the integrity of the support grid, and provides a more solid guarantee for the precise forming of the upper pipe rack. It is simple in construction yet highly effective.

[0011] Preferably, the lateral stabilization system includes two fixed-length diagonal braces, which are arranged symmetrically in a figure-eight shape on adjacent sides of the main upright.

[0012] The symmetrical V-shaped arrangement provides lateral restraint to the main uprights from multiple directions, achieving all-around stability. This arrangement ensures effective support for the main uprights under lateral forces from any direction, improving the stress state, increasing the buckling critical load, and preventing torque generation, making it an effective means of enhancing stability.

[0013] Preferably, the top of the main upright is fixed with an installation platform for installing the jack.

[0014] The installation platform provides a flat and stable mounting surface for the jacks, ensuring that the load is evenly distributed to the main upright and avoiding localized pressure damage. It simplifies the positioning and installation of the jacks, improves construction efficiency, and enhances connection reliability. The platform also strengthens the local rigidity of the top of the main upright.

[0015] Preferably, a base plate is fixed to the bottom of the main upright.

[0016] The base plate increases the contact area between the main uprights and the ground, reducing the pressure on the foundation, preventing subsidence, and enhancing its applicability on soft soil. At the same time, it also provides better anti-slip and anti-overturning stability, making it a key foundation component for ensuring the stability of the bottom boundary conditions.

[0017] Preferably, the base plate has mounting holes.

[0018] Mounting holes allow for the use of anchors to secure the base plate to the foundation, completely eliminating the risk of bottom slippage and reliably channeling horizontal forces into the ground. This significantly enhances the overall shear resistance and stability of the support system, particularly when subjected to eccentric or dynamic loads.

[0019] Preferably, the anchoring point is a ground anchor or a counterweight block fixed to the ground.

[0020] Two lateral force solutions are provided to suit different site conditions. Ground anchors are suitable for solid ground, providing reliable anchoring. Counterweights are suitable for hardened ground, offering flexible placement without damaging the surface. These two options ensure the lateral stabilization system functions effectively under various conditions.

[0021] Preferably, the cross-section of the top support beam is I-shaped.

[0022] I-beam cross-sections are economical sections with high bending resistance. They minimize deformation of the top support beam when subjected to bending moments, providing a flat support base for the formwork and helping to ensure the flatness of the bottom of the scaffold. Furthermore, I-beams are a standard profile with ample supply and high cost-effectiveness.

[0023] Preferably, both the first universal joint and the second universal joint are ball joints.

[0024] Ball joints can adapt to multi-dimensional angle changes, ensuring that no bending moment is generated at the connection point, keeping the brace in an ideal two-force state. This fully utilizes the member's performance, eliminates secondary stresses, improves joint reliability and lifespan, and reduces installation accuracy requirements.

[0025] The advantages of this utility model compared to the prior art are: This utility model presents a modular support system for cast-in-place concrete pipe racks, which combines mature jacks with an innovative lateral stabilization structure, demonstrating multiple beneficial effects.

[0026] First, the system adopts a modular design concept, with multiple support units working together, which gives the system good flexibility and adaptability. It can be flexibly configured and expanded according to different spans and load requirements of the pipe rack in actual projects, reducing material waste or insufficient support strength in traditional support methods.

[0027] Secondly, the system uses jacks as the core lifting component, leveraging their mature technology, large lifting force, and intuitive and reliable operation to provide strong support for the huge load of cast-in-place concrete. At the same time, it simplifies the process of adjusting the vertical height, which helps to improve construction efficiency.

[0028] Furthermore, the unique lateral stabilization system constitutes a prominent feature of this scheme. By forming a triangular stabilizing structure with the main upright through at least one fixed-length diagonal brace, and introducing constraints from the upper part of the main upright, horizontal loads can be effectively transferred to the anchor points. This enhances the support unit's resistance to lateral displacement and overturning, improving the overall stability of the support system in dynamic construction environments. The fixed-length diagonal brace is connected at both ends via universal joints, ensuring that the members primarily bear axial tensile and compressive forces during operation. This avoids complex bending moments at the nodes, making the force model clearer and more reasonable, and reducing the stringent requirements for component manufacturing and on-site installation accuracy, thus enhancing the system's engineering practicality and reliability.

[0029] Furthermore, the cooperation between the top support beam and the top support hinge seat helps to distribute and transfer the load evenly, and can adapt to small deflections, reducing local stress. The components of the entire system are mostly conventional components or easy-to-manufacture parts, which, while achieving enhanced functionality, also take into account manufacturing costs and ease of later maintenance, providing a safe, efficient, and economical support option for the construction of cast-in-place concrete pipe racks.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0038] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0039] This embodiment provides a modular support system for cast-in-place concrete pipe racks, including a top support beam 1 and at least two support units. The at least two support units are arranged at intervals along the length of the top support beam 1 to jointly support the top support beam. The support unit includes: The lifting support system includes a top support hinge seat 2 fixed to the bottom of the top support beam 1; The central lifting system includes a main upright 3 and a jack 4 disposed between the top support hinge seat 2 and the top of the main upright 3. The base of the jack 4 is fixedly connected to the top of the main upright 3. The lateral stabilization system includes at least one fixed-length diagonal brace 5; the upper end of the fixed-length diagonal brace 5 is connected to the upper part of the main upright 3 through a first universal joint 6, and its lower end is hinged to an anchor point 8 set on the ground through a second universal joint 7.

[0040] This scheme constructs a modular support system with clear division of labor and excellent stability and adaptability. The core component is the use of jack 4 as the central lifting element. Based on threaded or hydraulic principles, it provides stable and powerful vertical lifting force, effectively bearing the enormous load of the cast-in-place concrete pipe frame and ensuring the safety and reliability of the construction process. The design of the top support beam 1 and the top support hinge seat 2 effectively distributes and transfers the concentrated load. Simultaneously, the hinged form allows for slight adaptive adjustments under stress, avoiding the localized stress concentration problems that may occur with rigid connections. The lateral stabilization system forms a triangular stabilizing structure with the main upright 3 through fixed-length diagonal braces 5. This is a classic and efficient anti-lateral displacement solution in engineering, significantly enhancing the bending and overturning resistance of the main upright 3 and ensuring the stability of the entire support system under dynamic loads or accidental lateral forces. The fixed-length diagonal braces 5 are connected at both ends with universal joints. This design allows the members to bear only tensile and compressive forces, without having to bear bending moments. This not only fully utilizes the material properties of the members but also simplifies the connection structure and reduces manufacturing and installation complexity. The design of anchor point 8 ultimately transfers the force borne by the diagonal brace to the foundation, forming a complete force flow path. The entire system adopts a modular design concept, with at least two support units jointly supporting a top support beam 1. This combination method gives the system good scalability, enabling it to flexibly adapt to pipe rack construction scenarios with different spans and load requirements. At the same time, the modular components facilitate transportation, storage, and rapid assembly and disassembly, improving construction efficiency and reducing overall costs.

[0041] The upper end of the fixed-length diagonal brace 5 is connected to the upper part of the main upright 3 via a first universal joint 6, and its lower end is hinged to an anchor point 8 via a second universal joint 7. Universal joints 6 and 7 can be ball joints or other types of multi-degree-of-freedom hinge devices. Taking a ball joint as an example, it can adapt to possible multi-dimensional angle changes between the diagonal brace and the main upright, and between the diagonal brace and the anchor point, ensuring that no additional bending moment constraint is generated at the connection point, so that the fixed-length diagonal brace 5 is always in an ideal two-force member stress state. Those skilled in the art can select a suitable universal joint type according to actual needs, as long as it can achieve multi-directional rotation.

[0042] In this embodiment, jack 4 is a screw jack or a hydraulic jack.

[0043] Two mature and reliable jacking solutions, proven through long-term engineering practice, are offered. The screw jack utilizes the self-locking characteristic of its threaded joint to achieve mechanical self-locking after lifting, maintaining the jacking height for extended periods without settling. It offers precise positioning and relatively low maintenance requirements, making it suitable for applications requiring long-term pressure maintenance or precise fine-tuning. The hydraulic jack, utilizing Pascal's principle, can achieve a large lifting force with relatively small operating force. It is labor-saving, provides a smooth lifting process, and offers stepless adjustment within its lifting stroke range, making it particularly suitable for heavy-duty support applications requiring rapid lifting or extremely high lifting force. Both solutions use standard or commonly used parts, with ample market supply and convenient procurement and replacement, providing users with flexible options based on specific construction conditions and cost budgets.

[0044] In this embodiment, a horizontal scissor brace 9 is connected between the main uprights 3 of two adjacent support units.

[0045] The horizontal scissor bracing 9 connects the originally independent support units into a stable spatial frame structure in the horizontal plane. This connection method greatly enhances the entire support system's ability to resist horizontal loads (such as vibrations from construction equipment, wind loads, or lateral impacts during concrete pouring), effectively preventing synchronous or asynchronous lateral swaying and instability of the main uprights 3. By coordinating the work of multiple units, the overall stiffness and stability of the system are qualitatively improved, avoiding chain reactions caused by minor displacements of individual support units, ensuring the integrity of the support grid, and providing a more solid guarantee for the precise forming of the upper pipe rack. This structure is simple and uses less steel, but it significantly improves the system's safety redundancy.

[0046] In this embodiment, the lateral stabilization system includes two fixed-length diagonal braces 5, which are arranged symmetrically in a figure-eight shape on adjacent sides of the main upright 3.

[0047] The symmetrically arranged V-shaped bracing system provides lateral restraint to the upper part of the main upright 3 from two mutually perpendicular or nearly perpendicular directions. This arrangement ensures good support for the main upright 3 in all 360 degrees, guaranteeing that at least one bracing member is in efficient working condition regardless of the direction of the lateral force. This significantly improves the stress state of the main upright 3 and substantially increases its buckling critical load. The symmetrical arrangement also avoids torque that may be caused by asymmetrical support, ensuring that the main upright 3 is always in an ideal stress mode primarily bearing axial pressure, further enhancing the stability and safety of the support unit. This structural form, with its clear stress distribution and rational construction, is an effective means of achieving all-around stability.

[0048] In particular, when the lateral load mainly comes from one direction, a single fixed-length diagonal brace can be used; however, for multi-directional loads, it is recommended to use two fixed-length diagonal braces arranged symmetrically in a figure-eight shape.

[0049] In this embodiment, the top of the main upright 3 is fixed with an installation platform 10 for installing the jack 4.

[0050] The mounting platform 10 provides a flat, stable, and standard mounting base for the jack 4. This design ensures maximum contact area between the jack base and the top of the main upright 3, allowing the load to be evenly transferred to the main upright 3. This avoids localized indentation and structural damage that may be caused by point or line contact, ensuring smooth force transfer and structural integrity. The flat mounting surface also simplifies the positioning and installation process of the jack, improves construction efficiency, and facilitates the use of standard connectors (such as bolts) for fixing, enhancing the reliability of the connection. In addition, the platform also provides a certain degree of reinforcement, increasing the local rigidity of the top of the main upright 3 and preventing deformation caused by stress concentration.

[0051] The top support hinge seat 2 is fixed to the bottom of the top support beam 1 by welding or bolting; the base of the jack 4 is fixed to the mounting platform 10 at the top of the main upright 3 by bolting.

[0052] In this embodiment, a base plate 11 is fixed to the bottom of the main upright 3.

[0053] The base plate 11 increases the contact area between the main upright 3 and the ground or foundation, thereby effectively reducing the pressure per unit area of ​​the foundation and preventing the main upright 3 from sinking into the ground due to excessive pressure, ensuring the applicability of the support system on soft soil. The larger contact area also provides better anti-slip and anti-overturning stability. The base plate 11 has a simple structure and is easy to process and manufacture. It is a key basic component for ensuring the stability of the bottom boundary conditions of the support system and realizing the ideal mechanical model of "top support and bottom fixation".

[0054] In this embodiment, mounting holes are provided on the base plate 11.

[0055] The mounting holes provide the means to fix the base plate 11 to the concrete foundation or solid ground using anchors such as anchor bolts, expansion bolts, or steel pins. Through anchoring, the possibility of relative slippage between the bottom of the support unit and the foundation can be completely eliminated, reliably channeling the horizontal forces transmitted from the lateral stabilization system into the foundation, forming a complete closed-loop force flow path from the top support beam 1 to the foundation. This connection method greatly enhances the horizontal shear resistance and overall stability of the entire support system, especially when subjected to large eccentric or dynamic loads, where its advantages are even more pronounced.

[0056] In this embodiment, anchor point 8 is a ground anchor or counterweight fixed to the ground.

[0057] Two lateral force bearing solutions are provided to adapt to different site conditions. Ground anchors are suitable for solid ground with anchoring capabilities. They directly transfer the tension of the diagonal bracing to the deep foundation through mechanical interlocking or adhesive force, providing reliable anchoring without occupying ground space. Counterweights are suitable for hardened ground or situations where ground damage is not permitted. They utilize the friction generated by their own weight to balance the horizontal force transmitted from the diagonal bracing, offering flexible placement, no ground damage, and reusability. These two methods provide users with flexibility, allowing them to select the most suitable anchoring scheme based on the specific geological conditions and management requirements of the construction site, ensuring the lateral stabilization system always functions effectively.

[0058] In this embodiment, the cross-section of the top support beam 1 is I-shaped.

[0059] The I-beam cross-section is a highly efficient form of bending section. It possesses a high moment of inertia in the principal plane, allowing the top support beam 1 to withstand the same bending moment with a relatively small section height, or to have a greater load-bearing capacity at the same section height. This cross-sectional characteristic enables the top support beam 1 to better resist bending deformation caused by mid-span loads, providing a flatter and more stable support base for the upper formwork, thus helping to ensure the flatness of the bottom of the cast-in-place pipe scaffold. Furthermore, I-beams are a standard profile in the market, with ample supply, convenient procurement, and high cost-effectiveness.

[0060] In this embodiment, both the first universal joint 6 and the second universal joint 7 are ball joints.

[0061] A ball joint is a type of spatial hinge that allows rotation in multiple directions. It can accommodate multi-dimensional angle changes between the diagonal brace and the main upright 3, and between the diagonal brace and the anchor point 8, ensuring that no additional bending moment constraint is generated at the connection point under any installation posture. This keeps the fixed-length diagonal brace 5 in an ideal two-force member state, bearing only axial tension and compression. This maximizes the load-bearing efficiency of the members, eliminates secondary stresses caused by constraint moments at the connection point, improves the reliability and service life of the connection node, and reduces the stringent requirements for installation accuracy, making the installation process more convenient.

[0062] Besides the ball joint used in the above embodiments, those skilled in the art can also choose other types of universal joints. For example, a cross-shaft universal joint can be used. Regardless of the specific form of the universal joint used, as long as it can achieve multi-dimensional rotation, so that the diagonal brace only bears axial force and avoids bending moment, it falls within the protection scope of this utility model.

[0063] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
