Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, specifically to a steel structure packaging frame. Background Technology

[0002] With the globalization of China's economy, an increasing number of steel structures manufactured in China are being exported overseas. The primary mode of transportation for steel structures is sea freight, which involves either container shipping or bulk carrier transport after the steel structures are packed into containers. During sea freight, the transport vessels are subject to significant lateral and longitudinal swaying due to wind and waves, causing the packaging frames to loosen and detach, resulting in components scattering, colliding and damaging each other, and damaging the container walls or other items in contact with the packaging. This poses significant safety risks and economic losses.

[0003] Currently, large steel structures are mainly packaged using bundled packaging. Although the packaging materials are lightweight and can firmly hold the package in place at the beginning of transportation, the lack of rigidity on both sides of the package and insufficient restraint on the components means that if the package sways excessively during transportation, the internal components can easily loosen and fall off. Excessive stress can also cause the binding ropes or steel straps to break. Furthermore, if components at different heights loosen, they can easily fall and squeeze each other, resulting in hard contact between components. This not only easily leads to surface abrasion and scratches on the components but also to local deformation due to collisions, thus affecting the quality of delivery. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel structure packaging frame for supporting, protecting, and limiting steel components. By hoisting the entire frame for cargo loading, it improves the efficiency of packaging and transferring steel components while providing effective protection, ensuring the quality of shipment and the safety of transportation.

[0005] This utility model is achieved through the following technical solution:

[0006] A steel structure packaging frame is provided, including a base frame and a hanger that is positioned directly above the base frame and is the same width as the base frame. Diagonal channel steels are welded and fixed between the four corners of the hanger and the four corners of the base frame. The base frame includes two parallel transverse long channel steels with their openings facing away from each other. Multiple longitudinal channel steels are vertically welded between the two transverse long channel steels at equal intervals. Diagonal angle steels are welded along one diagonal direction within the rectangular frame formed by two adjacent longitudinal channel steels and the transverse long channel steels. The hanger includes parallel transverse short channel steels with their openings facing each other. Longitudinal channel steels are connected to both ends and the midpoints of the two transverse short channel steels. Vertical channel steels are vertically connected downwards between the four corners of the hanger and the midpoints of both sides along the length of the hanger, respectively. Diagonal channel steels are welded between the lower end of the middle vertical channel steel and the upper ends of the vertical channel steels on both sides. Lifting lugs are vertically welded at the connections of the diagonal channel steels, vertical channel steels, and transverse short channel steels.

[0007] Furthermore, the lower end of each vertical channel steel corresponds to one end of the longitudinal channel steel on the base frame.

[0008] The lower end of each vertical channel steel is fixed at the same point on the horizontal long channel steel corresponding to the longitudinal channel steel in the base frame, in order to form a horizontal and vertical frame structure, which facilitates welding and ensures connection stability.

[0009] Furthermore, each transverse long channel steel has a reinforcing plate vertically welded inside the slot corresponding to the connection between the vertical channel steel and the longitudinal channel steel.

[0010] Reinforcing plates are welded to the grooves of the transverse long channel steel at the joints with the vertical and longitudinal channel steels to increase the structural strength of the joints and improve the overall stability of the packaging rack.

[0011] Furthermore, reinforcing ribs are welded to both sides of each vertical channel steel where it is individually connected to a horizontal long channel steel or a horizontal short channel steel.

[0012] By welding reinforcing ribs to both sides of the connection between the vertical channel steel and the horizontal long channel steel, the connection can be reinforced to ensure the stability of the connection.

[0013] Furthermore, the longitudinal channel steel and diagonal angle steel inside the base frame are all covered with cushioning pads.

[0014] By covering the longitudinal channel steel and diagonal angle steel inside the base frame with buffer pads, the steel components can be prevented from being scratched by friction with the base frame during hoisting or transportation, thus protecting the steel components and preventing wear. At the same time, the buffer pads can increase the friction between the steel components and the base frame, effectively reducing the lateral displacement of the steel components.

[0015] Furthermore, a connecting plate is welded and fixed in the upper slot of each vertical channel steel, and a connecting through hole is opened on the connecting plate. The web of the longitudinal channel steel has positioning through holes at both ends that are directly opposite to the connecting through holes. The vertical channel steel and the longitudinal channel steel are connected by bolts and nuts that pass through the connecting through holes and positioning through holes.

[0016] The upper slot of the vertical channel steel is fixed with the longitudinal channel steel by a fixed connecting plate and bolts and nuts, so that the longitudinal channel steel and the packaging frame can be detached and installed. Before packaging, it can be removed to facilitate the hoisting of steel components into the packaging frame. After hoisting, the longitudinal channel steel is bolted to the vertical channel steel on both sides to complete the packaging.

[0017] Furthermore, the lower ends of the web plates of the two transverse long channel steels are inclined downward to form clearance ends between the lower ends and the flange plates. The lower flange plates are bent and welded to the inclined clearance ends.

[0018] By opening the web plates at both ends of the transverse long channel steel and welding them together with the bent lower flange plates to align with the openings, wedge-shaped clearance ends are formed at both ends of the packaging frame. Compared with a planar structure, it is easier to pull the whole frame across obstacles when encountering obstacles, thus improving the convenience of traction and movement.

[0019] Furthermore, pull holes for movement are provided at both ends of the web of the two transverse long channel steels.

[0020] By opening pull holes at both ends of the web of the transverse long channel steel, steel wire ropes can be passed in to pull the packaging rack into or out of the container, which facilitates the movement of the packaging rack.

[0021] Furthermore, the lifting lug plate is a rectangular steel plate. The long side of the rectangular steel plate near the inclined channel steel is sloping upward to form a hook. The connection between the hook and the rectangular steel plate is provided with an arc transition, and the connection between the two sides of the hook forms a semi-circular transition surface.

[0022] The long side of the rectangular steel plate is slanted and opened to form a hook. The connection between the hook and the rectangular steel plate is formed with an arc transition, and the connection between the two sides of the hook forms a semi-circular transition surface, which is used to cooperate with the lifting cable for lifting and facilitates the smooth entry and exit of the lifting cable from the hook.

[0023] The beneficial effects of this utility model are:

[0024] This utility model utilizes a stable frame structure formed by welding channel steel and angle steel. Combined with a detachable longitudinal channel steel at the top, it facilitates the hoisting and placement of steel components. After hoisting, the longitudinal channel steel is connected to limit the vertical movement of the steel components. The lifting lugs hook onto the lifting ropes, allowing for easy hoisting and transfer of the entire packaging rack containing the steel components into a container. This design is suitable for container transportation in domestic and international projects, improving the overall packaging and transportation efficiency of steel components. Simultaneously, the frame structure effectively protects the internal steel components, preventing them from being squeezed and deformed during transportation, thus ensuring shipment quality and transportation safety.

[0032] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0033] like Figures 1-5 As shown, a steel structure packaging frame includes a base frame and a hanger that is positioned directly above the base frame and is the same width as the base frame. Diagonal channel steels 2 are welded and fixed between the four corners of the hanger and the four corners of the base frame. The base frame includes two parallel transverse long channel steels 1 with their openings facing away from each other. Multiple longitudinal channel steels 9 are vertically welded between the two transverse long channel steels 1 at equal intervals. Diagonal angle steels 8 are welded along one diagonal direction within the rectangular frame formed by two adjacent longitudinal channel steels 9 and transverse long channel steels 1. To prevent scratches caused by friction between the steel components and the base frame during transportation, cushioning pads are applied to both the longitudinal channel steels 9 and the diagonal angle steels 8 within the base frame.

[0034] The hanger includes parallel horizontal short channel steels 3 with their slots facing each other. Both ends of the two horizontal short channel steels 3 and the midpoint of the two horizontal short channel steels 3 are connected to longitudinal channel steels 9. The four corners of the hanger and the midpoints of both sides along the length of the hanger are respectively connected to vertical channel steels 4 vertically between the two horizontal long channel steels 1. The lower end of each vertical channel steel 4 corresponds to one end of the longitudinal channel steel 9 on the base frame.

[0035] The lower end of the vertical channel steel 4 in the middle is welded to the upper end of the vertical channel steel 4 on both sides, and the inclined channel steel 2 is welded to the upper end of the vertical channel steel 4 on both sides. The connection between the inclined channel steel 2, the vertical channel steel 4 and the transverse short channel steel 3 is vertically welded with lifting lugs 5. The lifting lugs 5 are rectangular steel plates. The long side of the rectangular steel plate near the inclined channel steel 2 is inclined upward to form a hook 16. The connection between the hook 16 and the rectangular steel plate is provided with an arc transition. The connection between the hooks on both sides forms a semi-circular transition surface.

[0036] To improve the stability of the connection, a reinforcing plate 6 is vertically welded into the groove of each transverse long channel steel 1 corresponding to the connection between the vertical channel steel 4 and the longitudinal channel steel 9. Reinforcing ribs 7 are welded to both sides of each connection where the vertical channel steel 4 is individually connected to the transverse long channel steel 1 or individually connected to the transverse short channel steel 3.

[0037] Each vertical channel steel 4 has a connecting plate 11 welded and fixed in the upper slot. The connecting plate 11 has a connecting through hole. The web of the longitudinal channel steel 9 has positioning through holes at both ends that are directly opposite to the connecting through holes. The vertical channel steel 4 and the longitudinal channel steel 9 are connected by bolts 12 and nuts 13 that pass through the connecting through holes and positioning through holes.

[0038] The lower ends of the webs of the two transverse long channel steels 1 are inclined downwards to form clearance ends 14 between the lower part of the web and the flange plate. The lower flange plate is bent and welded to the inclined clearance end. Pull holes 15 for movement are provided at both ends of the webs of the two transverse long channel steels 1.

[0039] In this embodiment, the transverse long channel steel 1 has a specification of 18a, the longitudinal channel steel and transverse short channel steel 3 in the base frame both have a specification of 14a, and the longitudinal channel steel and oblique channel steel 2 in the hanger both have a specification of 12.

[0040] In use, the longitudinal channel steel 9 inside the lifting frame is disassembled, and the steel components to be transported are lifted and placed into the packaging frame using lifting tools. Supported by the base frame, once the steel components are full, the longitudinal channel steel 9 is connected to the vertical channel steel 4 on both sides of the packaging frame using bolts 12 and nuts 13 to complete the encapsulation of the steel components. To ensure transportation safety, steel wire ropes can be used to connect both ends of the steel components to the longitudinal channel steel 9 at both ends of the base frame to limit lateral displacement of the steel components. By using lifting ropes to suspend the workpiece onto the hooks 16 of the lifting lugs 5, the entire packaging frame can be lifted to the container opening. Steel wire ropes are then inserted through the pull holes 15 at both ends of the web of the transverse long channel steel 1 to pull the packaging frame into the container, facilitating the lifting and transfer of the packaging frame. Because the frame structure of the packaging frame encloses the steel components, it acts as a protective skeleton. During transportation, the packaging frame provides support and protection, making the steel components less susceptible to damage. Furthermore, the overall lifting and transfer method improves the efficiency of packaging and transferring the steel components.
