Description

Technical Field

[0001] This utility model relates to the field of frame steel structure installation technology, and in particular to a temporary support and hanger for a multi-layer cantilever beam of a steel structure frame unit. Background Technology

[0002] The trend towards large-scale and integrated petrochemical engineering projects is evident. To overcome the challenges of short project timelines, heavy workloads, and increasingly stringent safety, quality, and environmental standards, traditional engineering construction organization models have become increasingly ineffective, making modular construction a new development trend. For example, large petrochemical plants can be rationally divided along their axial direction into several steel frame units. Each frame unit has multiple H-shaped steel columns arranged horizontally and vertically, supporting multi-layered horizontal beams arranged vertically. The plan is a grid structure with multiple rectangular frames, and the nodes are the aforementioned H-shaped steel columns. Due to the need for modular installation, some beams in the steel frame units are cantilevered before installation. To prevent deflection of the cantilever beams during hoisting and before fixed installation, temporary reinforcement of the multi-layered cantilever beams is required. Furthermore, since the removal of these temporary reinforcement structures involves high-altitude work, they need to be easily dismantled. Utility Model Content

[0003] This utility model provides a temporary support for a multi-layer cantilever beam of a steel structure frame unit to solve the technical problems existing in the prior art. It can be used for the temporary fixing of the multi-layer cantilever beam of the steel structure frame unit, thereby avoiding the bending deformation of the multi-layer cantilever beam of the steel structure frame unit during hoisting and before fixed installation. In addition, the temporary support is easy to dismantle and can meet the needs of frame steel structure installation.

[0004] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is: a temporary support frame for a multi-layer cantilever beam of a steel structure frame unit. The steel structure frame unit is provided with multiple steel columns arranged in rows and columns, and multi-layer cantilever beams arranged in columns are supported on the steel columns. The temporary support frame includes at least two support units, each of which corresponds to a column of cantilever beams on the steel structure frame unit. The support unit is provided with a vertical hanger, which is hung on the cantilever end of the top cantilever beam and connected to the cantilever end of a column of cantilever beams by a detachable connection structure. The cantilever end of the top cantilever beam is supported by a diagonal brace, and the lower end of the diagonal brace is connected to the outer column of the steel structure frame unit.

[0005] Based on the above solution, the present invention has made the following improvements:

[0006] The main body of the vertical hanger includes two back-to-back channel steels, which are respectively set on both sides of the cantilever beam. They are connected from top to bottom by a top layer high-strength bolt, a middle layer high-strength bolt, and a bottom layer high-strength bolt. The top layer high-strength bolt is hung on the cantilever end of the top layer cantilever beam, the middle layer high-strength bolt is cross-braced below the cantilever end of the corresponding middle layer cantilever beam, and the bottom layer high-strength bolt is cross-braced below the cantilever end of the bottom layer cantilever beam.

[0007] A limiting member is provided on each of the left and right sides of the bottom high-strength bolt, and the limiting member is fixed to the bottom cantilever beam below the cantilever end.

[0008] The lower end of the diagonal brace is connected to the support ear plate I via a pin I, and the support ear plate I is fixed to the outer column of the steel structure frame unit.

[0009] The upper end of the diagonal brace is connected to the support ear plate II via a pin II, and the support ear plate II is fixed below the top cantilever beam.

[0010] The pin II passes through the two channel steels, and the two channel steels have vertical elongated holes, through which the pin II is installed.

[0011] Each of the aforementioned support units is provided with a vertical hanger.

[0012] The advantages and positive effects of this utility model are as follows: It features a simple and reasonable structure with strong overall integrity. By setting multiple support units to support the cantilever ends of multi-layer cantilever beams one-to-one, it can be applied to the temporary support of the cantilever ends of multi-layer cantilever beams in steel structure frame units with different spans and layers, demonstrating strong applicability. By attaching the temporary supports to the outer columns of the steel structure frame unit, the weight of the cantilever end of the cantilever beam is transferred to the main body of the steel structure frame through these temporary supports. This ingenious design improves the mechanical performance and structural stability of the support structure, meeting the safety requirements during the construction phase of the cantilever beam's cantilever end. Furthermore, the temporary supports use easily assembled and disassembled channel steel supports connected by bolts, allowing for the reuse of support components and facilitating installation and maintenance, thus possessing broad application prospects. In summary, this utility model can be used for the temporary fixing of multi-layer cantilever beams in steel structure frame units, thereby preventing bending deformation of the multi-layer cantilever beams during hoisting and before fixed installation. Moreover, the temporary supports are easy to disassemble, meeting the needs of frame-type steel structure installation. Attached Figure Description

[0016] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings:

[0017] Please see Figure 1 and Figure 2 A temporary support frame for a multi-layer cantilever beam of a steel structure frame unit is disclosed. The steel structure frame unit has multiple steel columns arranged in rows and columns, and multi-layer cantilever beams arranged in columns are supported on the steel columns. The temporary support frame includes at least two support units, each of which corresponds to a column of cantilever beams on the steel structure frame unit. Each support unit is provided with a vertical hanger 1, which is hung on the cantilever end of the top cantilever beam 10 and is connected to the cantilever end of a column of cantilever beams by a detachable connection structure. The cantilever end of the top cantilever beam is supported by a diagonal brace 2, and the lower end of the diagonal brace 2 is connected to the outer column 11 of the steel structure frame unit.

[0018] Each cantilever beam is supported by a single support unit. The support unit utilizes the cantilever end of the top-level cantilever beam as its suspension point. The cantilever end of the top-level cantilever beam is supported by diagonal braces, which are anchored to the outer columns of the steel frame unit. These outer columns provide support to the diagonal braces, thus stabilizing the cantilever end of the top-level cantilever beam. The stable cantilever end of the top-level cantilever beam then serves as the suspension point, providing support to the support unit. The structure itself acts as the fulcrum, resulting in a simple, stable, and highly deformation-resistant design. The support unit is connected to the cantilever end of the cantilever beam using a detachable structure that is not directly connected or fastened. After the cantilever end of the steel frame unit's cantilever beam is fixed into a stable unit, it can be quickly dismantled simply by removing the pins and high-strength bolts from the support unit.

[0019] The more preferred solution in this embodiment is as follows:

[0020] All the vertical hangers 1 within the same facade are connected by horizontal bracing (not shown in the figure). The horizontal bracing can be a formal steel beam on the same floor of the steel structure frame unit, or it can be a beam used for temporary support. The horizontal bracing plays a lateral supporting role in the structure and is a rigid component. By combining with the vertical hangers to form a stable system, it can better prevent deformation of the cantilever end of the cantilever beam of the steel structure frame unit.

[0021] The main body of the vertical hanger 1 includes two back-to-back channel steels, which are respectively set on both sides of the cantilever beam. From top to bottom, they are connected by a top-layer high-strength bolt 3, a middle-layer high-strength bolt 4, and a bottom-layer high-strength bolt 5. The top-layer high-strength bolt 3 is hung on the cantilever end of the top-layer cantilever beam 10, the middle-layer high-strength bolt 4 is cross-braced under the cantilever end of the corresponding middle-layer cantilever beam 9, and the bottom-layer high-strength bolt 5 is cross-braced under the cantilever end of the bottom-layer cantilever beam 8.

[0022] The cantilever beams are secured at their cantilever ends by two back-to-back channel steel sections connected with high-strength bolts. During dismantling, the bolts are loosened to detach the vertical support from the cantilever beams. The vertical support is then removed using a crane or electric hoist, simplifying removal, reducing high-altitude work, minimizing crane or hoist usage time, and saving labor. The cantilever ends of the top-level cantilever beams are supported by diagonal braces at the bottom and secured by high-strength bolts at the top. These high-strength bolts on the top-level crossbeams bear the weight of the support unit and the downward vertical force of each cantilever section, effectively preventing deformation of the cantilever beams at each level. The middle and bottom-level cantilever beams use high-strength bolt crossbeams at the bottom of their cantilever ends to effectively prevent bending deformation under gravity.

[0023] A limiting member 7 is provided on each of the left and right sides of the bottom high-strength bolt 5, and the limiting member 7 is fixedly connected to the cantilever end of the bottom cantilever beam 8.

[0024] Because of the height of the vertical hanger, it is prone to instability due to its high center of gravity or slippage on the cantilever beam, which could lead to hanger collapse. Therefore, this invention fully considers the bottom stability of the hanger and designs a horizontal limiting component to ensure the verticality of the vertical hanger installation and limit the horizontal displacement of the hanger, thereby improving the structural stability and installation accuracy of the hanger.

[0025] The lower end of the diagonal brace 2 is connected to the support ear plate I6-1 via a pin I, and the support ear plate I6-1 is fixed on the outer column 11 of the steel structure frame unit.

[0026] The lower end of the diagonal brace is connected to the support ear plate I by a pin I. During installation, the inclination angle of the diagonal brace can be freely adjusted according to the position of the support ear plate II on the top cantilever beam. When dismantling, the diagonal brace can be detached from the outer column of the steel structure frame unit by pulling out the pin I. The support ear plate I does not need to be removed, and dismantling is simple.

[0027] The upper end of the diagonal brace 2 is connected to the support ear plate II 6-2 via a pin II, and the support ear plate II 6-2 is fixed below the top cantilever beam 10.

[0028] The upper end of the diagonal brace is connected to the support ear plate II by a pin II. During installation, the inclination angle of the diagonal brace can be freely adjusted according to the position of the support ear plate II on the top cantilever beam. When dismantling, the diagonal brace can be detached from the top cantilever beam of the steel structure frame unit by pulling out the pin II. The support ear plate II does not need to be removed, and dismantling is simple.

[0029] The pin II passes through the two channel steels, and the two channel steels have vertical elongated holes, through which the pin II is installed.

[0030] Vertical elongated holes are designed on the two channel steels that make up the vertical hanger. These holes prevent the vertical hanger from being subjected to the force of pin II, thus ensuring that all the vertical forces borne by the cantilever beams of each layer on the vertical hanger are concentrated on the diagonal braces and the high-strength bolts on the top cantilever beam.

[0031] Each of the aforementioned support units is equipped with a vertical hanger 1, which has a simple structure and is easy to install and dismantle.

[0032] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and these all fall within the protection scope of the present invention.
