Description

Technical Field

[0001] This invention relates to the field of prefabricated support and hanger technology, specifically a novel perforated angle steel prefabricated support and hanger system. Background Technology

[0002] Supports and hangers are fundamental components in the construction of building electromechanical, chemical pipeline, and fire protection engineering. They are used to support the weight of pipes, cable trays, or various equipment and transfer the load to the building's load-bearing structure. At the same time, they limit the displacement and vibration of pipelines or equipment during operation. As modern building electromechanical pipelines become increasingly complex, support and hanger systems not only need to have sufficiently high load-bearing capacity, but also need to adapt to various complex spatial intersection environments.

[0003] Traditional supports and hangers are typically fabricated and installed using on-site material cutting and welding. However, on-site hot work and welding are not only inefficient but also pose significant fire safety hazards. Furthermore, the welded areas are highly susceptible to damaging the anti-corrosion coating of the steel, leading to rust and corrosion of the supports and hangers during later use and reducing the system's lifespan. Therefore, in order to eliminate on-site hot work, improve construction efficiency, and achieve standardized operations, prefabricated supports and hangers, which are mechanically connected and spliced ​​using profiles and fasteners, have emerged and are gradually becoming the industry mainstream.

[0004] Currently, most common angle steel prefabricated supports on the market use general-purpose angle steel with evenly distributed round holes. At the connection nodes between the uprights and crossarms, right-angle brackets are used in conjunction with standard hexagonal bolts for locking. However, the single round hole profile lacks flexible adjustment margin during on-site installation, has poor adaptability to working conditions, and makes it difficult to achieve high-precision adjustment of pipe elevation and level. Furthermore, the standard bolts tend to rotate under tightening force, requiring workers to use two wrenches, which is not only time-consuming and labor-intensive but also increases the difficulty of construction in narrow spaces. At the same time, the existing simple bracket connection method lacks comprehensive rigid constraint between the angle steel uprights and crossarms under multi-dimensional stress conditions, causing slippage at the nodes. This can lead to overall twisting and deformation of the integrated support when bearing heavy loads, posing a safety hazard. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a novel perforated angle steel prefabricated support system, which solves the problems of low installation and adjustment accuracy of existing prefabricated supports and the lack of multi-dimensional rigid constraints at the connection nodes between the uprights and crossarms, leading to node slippage and overall structural deformation under load.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel perforated angle steel prefabricated support system, comprising an upright and a crossbeam. Elliptical holes are spaced apart on the outer sides of both the upright and the crossbeam. The end of the crossbeam is fitted into the inner wall of the upright, forming an embedded overlapping structure between the upright and the crossbeam. A right-angle connector is provided at the connection between the upright and the crossbeam. Multiple square holes are equidistantly spaced on the outer side of the right-angle connector, with the spacing between the square holes being smaller than the spacing between the elliptical holes. The crossbeam is fixedly connected to the right-angle connector using round-headed square-neck bolts. The right-angle connector is fixedly connected to the side plate of the upright and the side plate and upper flange plate of the crossbeam using anti-slip bolts. The upright and the crossbeam are spliced ​​together to form a comprehensive support system.

[0007] Preferably, a base is provided at the top of the upright, and a U-shaped stamping part is fixedly connected to the bottom of the base. A square hole is provided on each of the three outer sides of the U-shaped stamping part, and a round head square neck bolt is inserted through the inner side of the square hole. The upright is fixedly connected to the base through the round head square neck bolt.

[0008] Preferably, the uprights and crossarms are assembled by round-headed square-neck bolts to form a comprehensive support frame, and two of the comprehensive support frames are assembled by assembly connectors to form a double-row heavy-duty support frame.

[0009] Preferably, the assembly connector is fixedly connected to the upright by the round-headed square-neck bolt.

[0010] Preferably, mounting holes are provided on both the left and right sides of the top of the base.

[0011] Preferably, the uprights and crossarms are made of angle steel with a thickness of 4-6mm, and the elliptical holes are spaced 30mm-100mm apart on the uprights and crossarms.

[0012] Preferably, the stamping direction of the elliptical hole on the upright is perpendicular to the extension direction of the upright angle steel, and the stamping direction of the elliptical hole on the crossarm is parallel to the extension direction of the crossarm angle steel.

[0013] Preferably, the base and the U-shaped stamping part are fixed together as an integral structure by welding.

[0014] Preferably, the square neck portion of the round-headed square-neck bolt is adapted to the inner walls of the first square hole and the second square hole to provide anti-rotation limit during locking.

[0015] Preferably, a plurality of the assembly connectors are distributed at equal intervals along the length of the upright between the two integrated support brackets.

[0016] This invention provides a novel assembled support and hanger system for perforated angle steel. It has the following beneficial effects: 1. This invention improves the adaptability of the support system to different working conditions and the accuracy of installation and adjustment by opening elliptical holes on the uprights and crossarms. The square holes on the outer side of the right-angle connectors, combined with round-headed square-neck bolts, achieve anti-rotation limiting and initial fixation. Anti-slip bolts are then used to securely connect the support system to the side plates of the uprights, the side plates of the crossarms, and the upper flange plates in multiple dimensions. This modular assembly avoids the welding process of traditional manufacturing, improves the convenience of on-site installation, and firmly combines the uprights and crossarms into a comprehensive support system, preventing structural deformation of the support system under load.

[0017] 2. This invention achieves a wrap-around locking and fixing of the base and the top of the upright by fixing the U-shaped stamping part to the bottom of the base and using the square holes on the three outer sides of the U-shaped stamping part with round head square neck bolts for fastening. The mounting holes reserved on the left and right sides of the top of the base provide a standardized interface for fixing the integrated support and hanger, which can improve the overall hoisting efficiency on the construction site while ensuring the strength of the connection node.

[0018] 3. This invention places two conventional integrated support brackets opposite each other, evenly places multiple assembly connectors between them, and uses round-headed square-neck bolts to horizontally tie and fix the assembly connectors to the uprights of the integrated support brackets on both sides, quickly assembling them into a double-row heavy-duty support bracket. This can improve the load-bearing capacity of the support bracket system without replacing the basic angle steel profile, and improve the practicality and working condition expansion capability of standard perforated angle steel accessories.

[0021] The technical solutions in 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.

[0022] Reference Figure 2 , Figure 5 and Figure 6 This invention provides a novel perforated angle steel prefabricated support system, including an upright 1 and a crossbeam 2. Elliptical holes 7 are spaced apart on the outer sides of both the upright 1 and the crossbeam 2. These elliptical holes 7 enhance the flexibility of position adjustment during assembly. The end of the crossbeam 2 is fitted into the inner wall of the upright 1, forming an embedded overlapping structure between the upright 1 and the crossbeam 2. A right-angle connector 4 is provided at the connection between the upright 1 and the crossbeam 2, providing a multi-dimensional rigid connection at the node. Multiple square holes 12 are equidistantly spaced on the outer side of the right-angle connector 4, with the spacing between the square holes 12 being smaller than the spacing of the elliptical holes 7. The crossbeam 2 is connected by round-headed square-neck bolts. Bolt 5 is fixedly connected to right-angle connector 4. Right-angle connector 4 is fixedly connected to the side plate of upright 1 and the side plate and upper flange plate of crossarm 2 respectively by anti-slip bolt 11. Multi-dimensional locking is used to prevent deformation of upright 1 and crossarm 2 when bearing heavy objects. Upright 1 and crossarm 2 are spliced ​​to form a comprehensive support frame. Upright 1 and crossarm 2 are both made of angle steel with a thickness of 4mm-6mm. The interval of the elliptical holes 7 on upright 1 and crossarm 2 is 30mm-100mm. The stamping direction of the elliptical holes 7 on upright 1 is perpendicular to the extension direction of the angle steel of upright 1, and the stamping direction of the elliptical holes 7 on crossarm 2 is parallel to the extension direction of the angle steel of crossarm 2. Specifically, the end dimensions of the crossarm 2 are adapted to the inner space of the upright 1. The end of the crossarm 2 is directly fitted into the inner wall of the upright 1, forming an embedded overlapping structure between the upright 1 and the crossarm 2. The elliptical holes 7 on the upright 1 and the crossarm 2 are designed with mutually perpendicular and parallel stamping directions, allowing for precise three-dimensional adjustment according to the actual elevation and levelness requirements of the pipeline during on-site assembly, greatly improving the adaptability to working conditions. At the same time, the right-angle connector 4, in conjunction with the round-head square-neck bolt 5 and the anti-slip bolt 11, ensures that the side... By limiting and locking in multiple dimensions such as direction and vertical, a force-bearing node with all-round rigid constraint on the upright 1 and crossarm 2 is formed. This solves the problem of node slippage and overall structural distortion that occurs under load in traditional simple bolt or angle bracket connections. It ensures the safety and structural stability of the support system under heavy load. Furthermore, by using different square holes 12 on the outside of the right-angle connector 4 to align and fix with the elliptical holes 7 on the upright 1, the vertical adjustment accuracy of the support system can be effectively improved, meeting the construction elevation requirements.

[0023] Reference Figure 1 , Figure 4 and Figure 9 The top of the upright 1 is provided with a base 3, which is used to install the entire support system. The bottom of the base 3 is fixedly connected with a U-shaped stamping part 8. The U-shaped stamping part 8 can be inserted into the top end of the upright 1 to form a three-sided contact. Square holes 9 are opened on the three outer sides of the U-shaped stamping part 8. Round head square neck bolts 5 are inserted through the inner side of the square holes 9. The upright 1 is fixedly connected to the base 3 through the round head square neck bolts 5, thus forming a top force-bearing node that is resistant to pull-out. The top left and right sides of the base 3 are provided with mounting holes 10, which facilitate the insertion of anchor bolts for quick installation. The base 3 and the U-shaped stamping part 8 are fixed together by welding to ensure that the node has sufficient shear resistance and overall tensile strength. Specifically, the base 3 and its bottom U-shaped stamping part 8 constitute the top mounting component of the support system. During actual installation, the U-shaped stamping part 8 is inserted into the top of the upright 1, and the upright 1 is locked by passing the round head square neck bolt 5 through the square hole 9. Compared with the traditional single-sided corner code connection, the combination connection method of three-sided wrapping can disperse the stress concentration phenomenon at the connection node. At the same time, the pre-made mounting holes 10 allow the workers to directly use standard anchors to fix the assembled integrated support to the building structure, saving the on-site measurement, drilling and cumbersome welding process, and improving the overall construction efficiency of on-site hoisting.

[0024] As a preferred implementation method, refer to Figure 1 , Figure 7 and Figure 8After the upright 1 and the crossbeam 2 are spliced ​​together by round head square neck bolts 5, they form a comprehensive support frame. The two comprehensive supports are spliced ​​together by assembly connectors 6 to form a double-row heavy-duty support frame, which can multiply the overall load-bearing capacity of the support system without changing the specifications of the foundation profile. The assembly connectors 6 are fixedly connected to the upright 1 by round head square neck bolts 5. Multiple assembly connectors 6 are distributed at equal intervals along the length of the upright 1 between the two comprehensive supports to ensure that the stress can be evenly transmitted and to prevent the upright 1 from undergoing slenderness ratio instability deformation. Specifically, when using integrated support systems for pipelines or large equipment under heavy loads, there is no need to customize thicker or larger angle steel. Simply place two conventionally assembled single-row integrated support systems opposite each other, use the assembly connectors 6 as lateral support bridges, and tightly tie the uprights 1 on both sides together with round-headed square-neck bolts 5. The force of the single-row support is transformed into a stable double-row spatial truss structure through the equidistantly distributed assembly connectors 6, which improves the overall rigidity and bending load-bearing capacity of the support system and enhances the working conditions versatility and practicality of general-purpose perforated angle steel and standard accessories.

[0025] As another preferred implementation, refer to Figure 3 , Figure 6 and Figure 9 The square neck portion of the round head square neck bolt 5 is adapted to the inner wall of square hole 9 and square hole 12 to provide anti-rotation limit when locked. When locked, square hole 9 and square hole 12 can provide reliable anti-rotation limit to prevent the round head square neck bolt 5 from slipping and rotating. Specifically, by precisely inserting the square neck of the round head square neck bolt 5 into the square hole 9 of the U-shaped stamping part 8 on the base 3 and the square hole 12 of the right angle connector 4, the round head square neck bolt 5 obtains anti-rotation mechanical support force, making it easier for workers to install nuts on the round head square neck bolt 5.

[0026] Working principle: The perforated angle steel prefabricated support is composed of uprights 1 and crossarms 2. Uprights 1 are made of 4-6mm thick angle steel, with elliptical holes 7 of 12mm-14mm diameter punched at intervals of 30-100mm perpendicular to the angle steel. Crossarms 2 are also made of 4mm-6mm thick angle steel, with elliptical holes 7 of 12mm-14mm diameter punched at intervals of 30mm-100mm parallel to the angle steel. This improves the adaptability and adjustment accuracy of the support system. During actual on-site assembly, the ends of crossarms 2 are first aligned and pushed in. On the inner side of the upright 1, the crossbeam 2 is fitted into the inner wall of the upright 1, completing the embedded overlap. This embedded overlap not only allows for pre-positioning during installation but also effectively distributes the force. Since the outer side of the right-angle connector 4 has multiple square holes 12 at equal intervals, and the spacing of the square holes 12 is smaller than the spacing of the elliptical holes 7, during fixing, the vertical adjustment accuracy can be improved by aligning the different square holes 12 on the outer side of the right-angle connector 4 with the elliptical holes 7 on the upright 1. The Y-axis is connected using round-head square-neck bolts 5. Right-angle connectors 4 are connected to the side plates of the upright 1 and crossarm 2 in the X-axis direction using anti-slip bolts 11. Furthermore, right-angle connectors 4 are connected to the upper flange of the crossarm 2 in the Z-axis direction via anti-slip bolts 11. This connects the upright 1 and crossarm 2 into a single unit, preventing deformation of the integrated support under load. The right-angle connectors 4 are also connected to the side plates of the upright 1 via anti-slip bolts 11 within the elliptical holes 7 of the upright 1. A U-shaped... The stamped part 8 has square holes 9 on its three outer sides. Round head square neck bolts 5 are inserted through the inner side of the square holes 9. The U-shaped stamped part 8 is fixed to the upright 1 through the square holes 9, and then the base 3 is fixed to the top of the upright 1. The top left and right sides of the base 3 have mounting holes 10. The installation of the integrated support can be completed through the mounting holes 10. The integrated support adopts a simple and easy-to-operate assembly installation method, avoiding the welding process of traditional technology and improving the convenience of on-site installation. Furthermore, when the load is heavy, by splicing two integrated supports and hangers together, placing multiple assembly connectors 6 between the two integrated supports and hangers, and fixing the uprights 1 of the two integrated supports and hangers to the assembly connectors 6 with round head square neck bolts 5, the two integrated supports and hangers can be assembled into a double-row heavy-duty support and hanger, thereby achieving a greater load-bearing capacity and improving the practicality of the angle steel prefabricated support and hanger system. Finally, the square neck of the round head square neck bolt 5 is inserted into the square hole 9 of the U-shaped stamping part 8 on the base 3 and the square hole 12 of the right angle connector 4, so that the round head square neck bolt 5 obtains anti-rotation mechanical support force. At this time, the fastening operation of the node can be completed by tightening the nut on one side with a wrench, which reduces the construction difficulty and labor intensity, while ensuring that the tightening torque can be accurately applied to ensure the long-term seismic stability of each connection point.

[0027] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
