Description

Technical Field

[0001] This invention relates to the field of steel structure platform technology, specifically a modular steel structure platform. Background Technology

[0002] In the construction of steel structure projects, modern steel structure platforms generally have advantages such as diverse forms, complete functions, and wide application. Their biggest feature is that they are fully assembled structures with flexible designs. They can be designed and manufactured to meet site requirements, functional requirements, and logistics requirements according to different site conditions.

[0003] A typical steel structure platform usually consists of decking, primary and secondary beams, columns, inter-column bracing, ladders, and railings. The design of the primary and secondary beams requires precise measurement and calculation based on the site environment. After processing the components to the corresponding dimensions, they are assembled on-site. For steel structure platforms made in this way, the measurement, calculation, and subsequent processing significantly affect the construction speed. Furthermore, the construction of a conventional steel structure platform requires fixing a large number of beams and columns first, followed by decking assembly. This process uses a large number of bolts and rivets, making the assembly cumbersome and the assembly environment complex, resulting in low assembly efficiency. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a modular steel structure platform that solves the problems of low construction speed and assembly efficiency of conventional steel structure platforms.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a modular steel structure platform, comprising several support frames and a platform frame mounted on the support frames. Ribs are fixedly installed at the bottom of the four corners of the platform frame's inner cavity. A receiving platform is fixedly installed at the end of each of the four ribs away from the platform frame. The receiving platform is fixedly installed on the top of the support frames. A positioning post is fixedly installed in the middle of the top of the receiving platform. Four triangular assembly plates are placed on the top of the ribs, between the platform frame and the positioning post. A double-entrance stepped groove is formed on the top of the triangular assembly plate near its long side. The double-entrance stepped groove specifically includes a top opening and two through-holes communicating with the top opening. The internal sliding mounting of the platform is equipped with a double-plate bracket. The double-hole stepped grooves on the two adjacent platform frames are adapted to the double-plate bracket. The double-plate bracket is used to connect the two adjacent platform frames. The top of the triangular assembly plate is provided with a stepped through groove that communicates with the double-hole stepped groove. A slider is slidably connected inside the stepped through groove. A locking spring is fixedly installed between the side of the slider away from the double-hole stepped groove and the inner wall of the stepped through groove. A pin is fixedly installed on the other side of the slider. The surface of the double-plate bracket is provided with a first pin hole that matches the pin, and the four sides of the platform frame are provided with a second pin hole that matches the pin. The inside of the double-hole stepped groove is provided with a third pin hole that matches the pin.

[0008] By adopting the above technical solution, a small modular platform can be directly constructed using the platform frame, support frame, receiving platform, and four triangular assembly plates. Assembly is convenient and does not require precise on-site measurement. Through the setting of double-hole stepped grooves, double-plate inserts, stepped through grooves, sliders, pins, and locking springs, two small modular platforms can be quickly assembled. With the cooperation of the first, second, and third pin holes, the connection between the two small modular platforms is ensured, while further improving the stability of the assembled steel structure platform. It is also easy to disassemble, greatly improving the construction speed and assembly efficiency, and making it more convenient to use.

[0009] The present invention is further configured such that: four pins are fixedly installed at even intervals on the top of the receiving platform and on the outer periphery of the positioning column, and the top of the triangular assembly plate is provided with an assembly opening that matches the pins.

[0010] By adopting the above technical solution and using the pins to limit the position of the triangular assembly plate, the stability of the triangular assembly plate assembly is ensured, while the tightness of the connection between the triangular assembly plate, the receiving platform and the platform frame is further strengthened, thereby ensuring the stability of the platform structure after the triangular assembly plate is assembled.

[0011] The present invention is further configured such that: a bottom limiting plate is fixedly connected to the bottom of the slider, and the top of the bottom limiting plate slides in contact with the bottom of the triangular assembly plate.

[0012] By adopting the above technical solution, the bottom limiting plate limits the position of the slider, ensuring that the pin spring works stably in the stepped through groove, thereby ensuring that the slider drives the pin rod to move stably and ensuring the assembly accuracy.

[0013] The present invention is further configured such that: the support frame includes a base, an adjusting cylinder is fixedly installed on the top of the base, a support rod is slidably installed through the top of the adjusting cylinder, and the adjusting cylinder and the support rod are fixedly connected by bolts.

[0014] The present invention is further configured such that: the top end of the support rod is fixedly connected to the bottom of the receiving platform, and a plurality of fixing holes are evenly spaced on the top of the base and on the outer periphery of the adjusting cylinder.

[0015] By adopting the above technical solution, the height of the platform frame off the ground can be adjusted using the support rod and the adjusting cylinder. It is convenient to use and easy to assemble. Furthermore, the setting of fixing holes allows screws to pass through the fixing holes, which further strengthens the connection between the base and the installation ground, making it more stable and convenient to use.

[0016] The present invention is further configured such that: the double plate holder includes a pad and two upright plates, and the two upright plates are respectively fixedly installed on both sides of the bottom of the pad.

[0017] The present invention is further configured such that: openings adapted to the pad are provided around the top of the platform frame, and the first pin hole is provided on the surface of the two upright plates.

[0018] By adopting the above technical solution, the opening is designed so that the pad plate is submerged in the opening when it crosses the two platform frames, ensuring the flatness of the top plane of the steel structure platform. The two upright plates are designed to fit into the two openings of the double-step groove. When the two platform frames are not being assembled, the two upright plates are inserted into the two openings of a triangular assembly plate. When the two platform frames are being assembled, the two upright plates are inserted into one opening of each of the two triangular assembly plates. With the pins in place, the position of the two platform frames is limited, thereby ensuring the stability of the assembly.

[0019] The present invention is further configured such that: the bottom of the triangular assembly plate is provided with an edge groove that matches the rib and the support platform.

[0020] By adopting the above technical solution and setting the edge groove, the triangular assembly plate can be directly assembled onto the rib and the support platform, making the assembly positioning more stable and faster, and further improving the assembly efficiency of the steel structure platform.

[0021] (III) Beneficial Effects

[0022] This invention provides a modular steel structure platform. It has the following advantages:

[0023] (1) This modular steel structure platform can directly form a small modular platform by using the platform frame, support frame, receiving platform and four triangular assembly plates. It is easy to assemble and does not require precise on-site measurement. Through the setting of double-hole stepped groove, double plate bracket, stepped through groove, slider, pin and locking spring, two small modular platforms can be quickly assembled. With the cooperation of the first pin hole, the second pin hole and the third pin hole, the connection between the two small modular platforms is ensured, while the stability of the assembled steel structure platform is further improved. It is also easy to disassemble, which greatly improves the construction speed and assembly efficiency, and makes it more convenient to use.

[0024] (2) The modular steel structure platform uses pins to limit the position of the triangular assembly plate, ensuring the stability of the triangular assembly plate assembly, while further strengthening the connection between the triangular assembly plate, the support platform and the platform frame, thereby ensuring the stability of the platform structure after the triangular assembly plate assembly is completed.

[0025] (3) The modular steel structure platform limits the position of the slider by setting the bottom limiting plate, ensuring that the pin spring works stably in the stepped through groove, thereby ensuring that the slider drives the pin rod to move stably and ensuring the assembly accuracy.

[0026] (4) This modular steel structure platform can adjust the height of the platform frame off the ground by using support rods and adjusting cylinders. It is convenient to use and easy to assemble. Furthermore, the fixed holes can be used to strengthen the connection between the base and the installation ground by passing screws through the fixed holes, making it more stable and convenient to use.

[0027] (5) The modular steel structure platform, through the setting of the opening, ensures that the pad plate is submerged in the opening when crossing the two platform frames, thus ensuring the flatness of the top plane of the steel structure platform. The setting of the two upright plates is adapted to the two through holes of the double-mouth stepped groove. When the two platform frames are not assembled, the two upright plates are inserted into the two through holes of a triangular assembly plate. When the two platform frames are assembled, the two upright plates are inserted into one through hole of the two triangular assembly plates respectively. With the setting of the pin, the position of the two platform frames is limited, thereby ensuring the stability of the assembly.

[0028] (6) The modular steel structure platform, through the setting of edge slots, ensures that the triangular assembly plate is directly assembled onto the ribs and the support platform, making the assembly positioning more stable and rapid, and further improving the assembly efficiency of the steel structure platform.
