Description

Technical Field

[0001] This utility model relates to the field of prefabricated modular data center technology, and in particular to a prefabricated modular data center enclosure suspension point structure. Background Technology

[0002] Prefabricated modular data centers are pre-engineered solutions where information technology equipment (such as servers, switches, firewalls, etc.), along with supporting power supply, cooling, fire protection, and monitoring equipment, are integrated into modular enclosures in a factory according to project requirements. These enclosures are then transported to the project site for assembly and stacking before being put into use. Due to their short construction cycle, high flexibility, and stable construction quality, they are gradually becoming the mainstream trend in data center construction.

[0003] The weight of the modular enclosure of the integrated equipment consists of the enclosure's own weight and the equipment's weight, with a total weight reaching 30-40 tons. Resisting such enormous gravity during hoisting requires a robust enclosure structure; therefore, the hoisting condition is a crucial factor to consider in the enclosure's structural design.

[0004] The location of the lifting points directly determines the force transmission system of the enclosure during the hoisting process, significantly impacting the enclosure's cross-sectional design. Simultaneously, the location of the lifting points also affects the enclosure's assembly and stacking methods, the spacing and sealing of joints between enclosures, and ultimately influences the prefabricated modular data center's load-bearing and seismic performance, installation efficiency, and waterproofing effectiveness.

[0005] To facilitate the hoisting and assembly of the enclosure, most manufacturers currently place the hoisting points on the top structure of the enclosure. In this case, the ceiling structure is the primary load-bearing component. To withstand the immense weight during hoisting, the longitudinal frame beams of the ceiling are typically designed as truss beams, the number and cross-section of the horizontal frames and secondary beams are increased, and frame columns are added between the ceiling frame beams and the floor frame beams for reinforcement. However, this reinforcement design does little to improve the load-bearing capacity of the enclosure when not in hoisting conditions. In other words, the reinforcement designed specifically for hoisting operations actually leads to significant material waste.

[0006] To address the aforementioned issues, this invention proposes a prefabricated modular data center enclosure suspension point structure. Summary of the Invention

[0007] To overcome the shortcomings of existing technologies, this utility model provides a simple and efficient prefabricated modular data center enclosure suspension point structure.

[0008] This utility model is achieved through the following technical solution:

[0009] A prefabricated modular data center enclosure suspension point structure consists of folded beams, sleeves, solid steel bars, limiting plates, connecting plates, and detachable support columns;

[0010] The folding beam is a C-shaped structure composed of square tubes with a web in the middle, which is fixedly connected to the longitudinal frame beam of the box body; the web of the middle section of the folding beam has a through hole for fixing the sleeve and allowing the solid steel bar to move in and out.

[0011] The detachable support column is perpendicular to the plane of the longitudinal frame beam of the box body, and its two ends are connected to the folding beam through connecting plates.

[0012] The solid steel bar is equipped with limiting plates at both ends to restrict its position in the fixed sleeve and prevent it from falling out of the fixed sleeve.

[0013] The folded beam is equipped with stiffening plates on both the left and right sides, which are fixedly connected to the longitudinal frame beam of the box floor to enhance the out-of-plane bending resistance of the folded beam and prevent out-of-plane instability of the folded beam section during hoisting.

[0014] The folded beams are divided into floor folded beams and roof folded beams;

[0015] The floor folding beams are installed at 1 / 3 of the position of the longitudinal frame beams of the box body floor, and two floor folding beams are installed on each longitudinal frame beam;

[0016] The top plate folding beams are installed at 1 / 3 of the position of the longitudinal frame beams of the top plate of the box body, and two top plate folding beams are installed on each longitudinal frame beam;

[0017] The floor folding beam is responsible for providing the connection points for hoisting during installation, and the top folding beam is responsible for providing the channel for wire rope hoisting and retrieval.

[0018] The floor folding beam is a C-shaped structure formed by butt welds of square tubes with webs in the middle, and the weld grade is level II; the floor folding beam and the longitudinal frame beam of the box floor are welded together on all four sides by butt welds, and the weld grade is level II.

[0019] The concave section of the C-shaped structure of the floor beam is used to provide expansion space for the concealed lifting points, thereby ensuring that the lifting points do not occupy the space of adjacent boxes when they are pulled out for use.

[0020] The top plate folded beam is a C-shaped structure made of ordinary square tubes welded together by butt welds, and the weld grade is level two.

[0021] The concave section of the C-shaped structure of the top plate folding beam is used to provide a passage for hoisting and retrieving the wire rope, thereby ensuring that the space of the adjacent box does not need to be occupied during hoisting.

[0022] The connecting plate is provided with bolt holes and is connected to the flange plate of the folding beam by welding.

[0023] The detachable support column is provided with end cap steel plates at both ends, and a joint connecting plate is fixedly connected to the end cap steel plate. The joint connecting plate is provided with bolt holes.

[0024] The detachable support column is connected to the connecting plate by bolts.

[0025] The sleeve is the same length as the width of the folded beam and is welded to the web of the folded beam by a fillet weld.

[0026] The length of the solid steel bar is the sum of the length of the concave section of the C-shaped folded beam structure and the width of the folded beam cross-section. The lifting point can be pulled out for use and hidden for retraction by moving the solid steel bar back and forth in the sleeve.

[0027] The beneficial effects of this utility model are: the prefabricated modular data center cabinet suspension point structure sets the suspension point position on the longitudinal frame beam of the cabinet floor, adopts a concave and concealable structural design, has a reasonable stress system, saves materials, the joint width between cabinets is the same as when the suspension point position is at the top, is easy to install, has a fast construction and deployment speed, has excellent comprehensive performance, and has a wide range of application scenarios.

Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0036] A prefabricated modular data center enclosure suspension point structure is set at the bottom of the prefabricated modular data center enclosure and consists of a folded beam 2, a sleeve 3, a solid steel bar 4, a limiting plate 5, a connecting plate 7, and a detachable support column 8.

[0037] The folding beam 2 is a C-shaped structure composed of square tubes with a web plate 9 in the middle, which is fixedly connected to the longitudinal frame beam 11 of the box body; the web plate in the middle section of the folding beam 2 has a through hole 10 for fixing the sleeve 3 and allowing the solid steel bar 4 to extend and retract.

[0038] The detachable support column 8 is perpendicular to the plane of the longitudinal frame beam 11 of the box body, and its two ends are connected to the folding beam 2 through the connecting plate 7.

[0039] The solid steel rod 4 is equipped with limiting plates 5 at both ends to limit the position of the solid steel rod 4 in the fixed sleeve 3 and prevent it from falling out of the fixed sleeve 3.

[0040] The left and right sides of the folded beam 2 are respectively provided with stiffening plates 1, which are fixedly connected to the longitudinal frame beam 11 of the box floor to enhance the out-of-plane bending resistance of the folded beam and avoid out-of-plane instability of the folded beam section during hoisting.

[0041] The folding beam 2 is divided into a floor folding beam 21 and a roof folding beam 22;

[0042] The floor folding beam 21 is set at 1 / 3 position of the longitudinal frame beam of the box body floor, and two floor folding beams 21 are set on each longitudinal frame beam;

[0043] The top plate folding beam 22 is set at 1 / 3 position of the longitudinal frame beam of the top plate of the box body, and two top plate folding beams 22 are set on each longitudinal frame beam;

[0044] The floor folding beam 21 is responsible for providing the connection position of the lifting point during hoisting, and the top plate folding beam 22 is responsible for providing the channel for wire rope hoisting and retrieval.

[0045] The floor folding beam 21 is a C-shaped structure formed by butt welds of square tubes with webs in the middle, and the weld grade is level II; the floor folding beam 21 and the longitudinal frame beam of the box floor are welded together on all four sides by butt welds, and the weld grade is level II.

[0046] The recessed section of the 21C-shaped floor beam is 250mm long and is used to provide telescopic space for the concealed suspension points, thereby ensuring that the suspension points do not occupy the space of adjacent boxes when they are pulled out for use.

[0047] The top plate folded beam 22 is a C-shaped structure made of ordinary square tubes welded together by butt welds, and the weld grade is level two.

[0048] The concave section of the 22C-shaped top plate folding beam is 250mm long and is used to provide a channel for hoisting and retrieving the wire rope, thereby ensuring that the space of the adjacent box does not need to be occupied during hoisting.

[0049] The connecting plate 7 is a 100mm*100mm steel plate with a wall thickness of 10mm. The steel plate has four bolt holes with a diameter of 22mm. The connecting steel plate 7 is set at the position of the floor folding beam 21 and the top plate folding beam 22, and is connected to the flange plate of the folding beam 2 by welding.

[0050] The detachable support column 8 is a 100*100mm square tube with a wall thickness of 10mm and a strength grade of Q355B. End cap steel plates 14 are provided at both ends of the square tube. The end cap steel plates 14 are connected to the square tube by butt welds. A joint connecting plate 12 is fixedly connected to the end cap steel plate 14. The connecting plate 14 is a 100*100mm steel plate with a thickness of 10mm and a strength grade of Q355B. Four bolt holes with a diameter of 22mm are provided on it.

[0051] The detachable support column 8 is connected to the connecting plate 7 by M20 8.8 ordinary bolts 13.

[0052] The sleeve 3 is a circular steel pipe with a diameter of 100mm, a wall thickness of 10mm, a length equal to the width of the folded beam, and a strength grade of Q355B. The sleeve 3 is placed at the opening 10 in the web plate 9 of the folded beam and is welded to the web plate 9 of the folded beam by a fillet weld, forming a sleeve-like shape. The sleeve 3 provides a channel for the solid steel bar 4 to be pulled and moved inside the folded beam 2, and at the same time plays a role in force transmission through contact with the steel bar 4.

[0053] The solid steel rod 4 is a cast cylinder with a diameter of 90mm. Its length is the sum of the length of the concave section of the C-shaped folded beam 2 and the width of the cross-section of the folded beam 2. Its strength grade is Q235B. Limiting plates 13 are welded to both ends along its length. The lifting point can be pulled out for use and retracted by moving the solid steel rod 4 back and forth in the sleeve 3 (pulling it out of the box and retracting it into the box).

[0054] The limiting steel plate 5 is a 120*120mm steel plate with a wall thickness of 10mm and a strength grade of Q355B. The steel plate is connected to the solid steel bar by fillet weld. The cross-section of the limiting steel plate is larger than that of the sleeve, so it can limit the position of the solid steel plate to be pulled outward and retracted inward. This ensures that the lifting point can only move within the concave section of the folded beam, and that the pulling of the lifting point will not occupy the space of the adjacent box.

[0055] Stiffening plate 1 is an equilateral right-angled triangular steel plate with a wall thickness of 10mm and a side length of 350mm, and a strength grade of Q355B. The stiffening plate is installed at the upper and lower flanges of the beam where the folded beam 2 contacts the longitudinal frame beam 11 of the box girder floor, and is connected to the folded beam and the longitudinal frame beam of the floor via butt welds (secondary welds). The stiffening plate 1 enhances the out-of-plane bending resistance of the folded beam, preventing out-of-plane instability of the folded beam section during hoisting.

[0056] The factory completed the processing of the prefabricated modular data center enclosure lifting point structure, including material cutting, welding, flaw detection, grinding and rust removal, and anti-corrosion treatment.

[0057] The solid steel rod 4 in the prefabricated modular data center enclosure lifting point structure can be pulled out and used as a lifting point. The lifting point is connected to the crane through a special lifting tool to carry out the lifting and positioning of the enclosure.

[0058] Once the container is accurately positioned, the operators dismantle the lifting tools inside the container, separating them from the lifting points. Then, the solid steel bar is pushed back into the container, and the lifting ropes are pulled out from the recessed section of the container's folding beam, ending the lifting operation. The detachable steel column is then removed, and subsequent container installation work can begin.

[0059] The embodiments described above are merely one specific implementation of this utility model. Ordinary variations and substitutions made by those skilled in the art within the scope of this utility model's technical solution should be included within the protection scope of this utility model.
