Technical Field

[0001] The present application relates to the field of new energy technology, and in particular to an energy storage frame and an energy storage device. Background Art

[0002] The main body of the prefabricated cabin generally adopts a frame structure. During the lifting and transportation of the prefabricated cabin, the bottom crossbeam supports a large force, so the strength requirements of the bottom crossbeam are particularly important. In addition, prefabricated cabins of different sizes usually have different load-bearing requirements, so the material and size selection of the bottom crossbeam becomes more troublesome. In order to ensure transportation safety, the material and specifications of the bottom crossbeam are often increased, resulting in excessive increase in the overall weight and cost of the prefabricated cabin.

[0007] In the above technical solution, by adding reinforcing plates to the end cross beams and / or the middle cross beams, the structural strength of the bottom cross beam can be improved.

[0008] As an optional technical solution of the present application, the plurality of bottom longitudinal beams include two end longitudinal beams arranged opposite to each other, and a middle longitudinal beam arranged between the two end longitudinal beams. When the two end cross beams are provided with the reinforcing plates on the sides facing the accommodating area, the middle longitudinal beam is connected between the reinforcing plates on the sides of the two end cross beams.

[0009] In the above technical solution, by adding a reinforcing plate to the end cross beam, and then connecting the middle longitudinal beam to the end cross beam through the reinforcing plate, the load strength of the end cross beam can be enhanced.

[0010] As an optional technical solution of the present application, the plurality of bottom longitudinal beams include two end longitudinal beams arranged opposite to each other, and a middle longitudinal beam arranged between the two end longitudinal beams. When the reinforcing plate is arranged on the side of the middle cross beam facing the accommodating area, the middle cross beam is connected between the two end cross beams, and the middle cross beam is mounted on the middle cross beam.

[0011] In the above technical solution, the middle longitudinal beam is connected to the end cross beam, and the middle cross beam is mounted on the middle longitudinal beam. By adding a reinforcing plate to the middle cross beam, the load strength of the middle cross beam can be improved.

[0012] As an optional technical solution of the present application, the energy storage frame further includes a plurality of columns. The plurality of columns are assembled with the plurality of bottom cross beams and / or the plurality of bottom longitudinal beams. At least part of the columns are supported by the bottom cross beams.

[0013] In the above technical solution, multiple bottom cross beams, multiple bottom longitudinal beams, and multiple columns are assembled together, and at least part of the columns are supported by the bottom cross beams. Since a reinforcing plate is installed on the inner side of the bottom cross beam, the structural strength of the bottom cross beam is relatively high, thereby increasing the stability of the overall structure.

[0017] In the above technical solution, the connection method between the reinforcing plate and the bottom cross beam is relatively stable, and the processing technology is simple and fast.

[0018] As an optional technical solution of the present application, the reinforcing plate is a steel plate.

[0019] In the above technical solution, a steel plate is used as a reinforcing plate. The steel plate has high tensile strength. The steel plate is installed on the inner side of the bottom cross beam, which is a tensile surface or a weak part. The steel plate can form a whole with the bottom cross beam to bear force together, thereby improving the stress state of the bottom cross beam, improving the bending and shearing capacity of the component (the reinforcement effect is better than increasing the cross section of the cross beam), reducing the effect of continued development of cracks, and greatly improving the bearing capacity and seismic resistance. In addition, by bonding the steel plate as a reinforcing plate for reinforcement, the ductility of the reinforced model beam is relatively superior, the effect of improving the bearing capacity is reliable, and the construction is simple and fast, the space occupied is small, the processing cycle is short, and the material consumption is small. After reinforcement, the strength, rigidity and stability of the structure can be significantly improved, and the cross-sectional size and weight of the reinforced component are basically not increased.

[0020] As an optional technical solution of the present application, the bottom cross beam is any one of square steel, rectangular steel, channel steel, H-shaped steel or I-shaped steel.

[0021] In the above technical solution, the bottom crossbeam is made of any one of square steel, rectangular steel (the height is increased on the basis of square steel, and the width is appropriately narrowed. Since the bottom crossbeam is mainly stressed in the height direction, the use of rectangular steel can increase the height in the load direction, so that the lateral shear stress is smaller), channel steel, H-shaped steel or I-shaped steel. These types of bottom crossbeams can be suitable for adding reinforcement plates, and the application range is wide. In particular, for the frame structure with square steel as the bottom crossbeam, the reinforcement is carried out by bonding steel plates as reinforcement plates, which is fast and has a better overall effect, and can greatly improve the bearing capacity and earthquake resistance of the original structure and components.

[0022] As an optional technical solution of the present application, the projection area of ​​the reinforcing plate on the side surface is smaller than the surface area of ​​the side surface.

[0023] In the above technical solution, the projection area of ​​the reinforcing plate on the side is smaller than the surface area of ​​the side, which can strengthen the structural strength of the bottom beam on the one hand, and avoid interference between the reinforcing plate and the original structure and connection relationship of the bottom beam on the other hand.

[0024] As an optional technical solution of the present application, the length of the reinforcing plate is 0.6-1 times the length of the bottom cross beam on which the reinforcing plate is provided.

[0025] In the above technical solution, the length of the reinforcing plate is 0.6-1 times the length of the bottom beam. On the one hand, it can ensure the improvement of the structural strength of the bottom beam, and on the other hand, it can avoid interference between the reinforcing plate and the original structure and connection relationship of the bottom beam in the length direction.

[0026] As an optional technical solution of the present application, the width of the reinforcing plate is 0.5-0.8 times the width of the bottom cross beam on which the reinforcing plate is provided.

[0027] In the above technical solution, the width of the reinforcing plate is 0.5-0.8 times the width of the bottom beam. On the one hand, it can ensure the improvement of the structural strength of the bottom beam, and on the other hand, it can avoid interference between the reinforcing plate and the original structure and connection relationship of the bottom beam in the width direction.

[0028] As an optional technical solution of the present application, the length range of the reinforcing plate is 3-6m; and / or the width range of the reinforcing plate is 100-250mm; and / or the thickness range of the reinforcing plate is 2-6mm.

[0029] In the above technical solution, the length, width and thickness of the reinforcing plate meet the above size range, which can ensure the improvement of the structural strength of the bottom beam and avoid the waste of materials.

[0030] In a second aspect, the present application provides an energy storage device, which includes an energy storage frame according to any one of the above embodiments.

[0031] In the energy storage device of the embodiment of the present application, a reinforcing plate is installed on the inner side of the bottom cross beam, and the reinforcing plate can form a whole with the bottom cross beam to bear force together, thereby strengthening the structural strength of the bottom cross beam, greatly improving the bearing capacity and seismic resistance, and will not cause excessive increase in the overall weight and cost.

DETAILED DESCRIPTION

[0044] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0045] See also Figures 1 to 3 In a first aspect, the present application provides an energy storage frame 100. The energy storage frame 100 includes a plurality of bottom cross beams 10 and a plurality of bottom longitudinal beams 20. The plurality of bottom cross beams 10 and the plurality of bottom longitudinal beams 20 are staggered to form a plurality of accommodating areas 30. The length of the bottom cross beam 10 is greater than the length of the bottom longitudinal beam 20. A reinforcing plate 40 is provided on a side 11 of at least one bottom cross beam 10 facing the accommodating area 30.

[0046] In the energy storage frame 100 of the embodiment of the present application, a reinforcing plate 40 is installed on the inner side of the bottom cross beam 10. The reinforcing plate 40 can form a whole with the bottom cross beam 10 to bear force together, thereby strengthening the structural strength of the bottom cross beam 10, greatly improving the load-bearing capacity and earthquake resistance, and will not cause excessive increase in the overall weight and cost.

[0047] Specifically, the energy storage frame 100 may be the main frame structure of an energy storage device (e.g., a prefabricated cabin, a container, etc.). The energy storage frame 100 is a cubic frame as a whole. The energy storage frame 100 includes a plurality of bottom cross beams 10 and a plurality of bottom longitudinal beams 20. For example Figure 1In the embodiment, the energy storage frame 100 includes three bottom cross beams 10 and eight bottom longitudinal beams 20. The multiple bottom cross beams 10 and the multiple bottom longitudinal beams 20 are all long columnar structures. The multiple bottom cross beams 10 and the multiple bottom longitudinal beams 20 are staggered to form multiple accommodating areas 30. Each accommodating area 30 is used to install a corresponding battery module. Among them, an angle is formed between the length extension direction of the multiple bottom cross beams 10 and the length extension direction of the multiple bottom longitudinal beams 20. In one example, the length extension direction of the multiple bottom cross beams 10 and the length extension direction of the multiple bottom longitudinal beams 20 can be perpendicular to each other.

[0048] The bottom cross beam 10 is usually used as the main support beam for bearing loads. The length of the bottom cross beam 10 is greater than the length of the bottom longitudinal beam 20, so as to facilitate the installation and bearing of the column 50 of the energy storage frame 100. The length of the bottom cross beam 10 is greater than the length of the bottom longitudinal beam 20, and the length of all the bottom cross beams 10 can be greater than the length of all the bottom longitudinal beams 20, or the length of the longest bottom cross beam 10 can be greater than the length of the longest bottom longitudinal beam 20. For example, Figure 3 As shown, when the plurality of bottom cross beams 10 include an end cross beam 12 and an intermediate cross beam 13, and the plurality of bottom longitudinal beams 20 include an end longitudinal beam 21 and an intermediate longitudinal beam 22, the end cross beam 12 is the longest bottom cross beam 10, and the end longitudinal beam 21 is the longest bottom longitudinal beam 20, then the length of the end cross beam 12 is greater than the length of the end longitudinal beam 21.

[0049] At least one of the sides 11 of the bottom cross beam 10 facing the receiving area 30 is provided with a reinforcing plate 40. That is, at least one of the sides 121 of the end cross beam 12 facing the receiving area 30 and the sides 131 of the middle cross beam 13 facing the receiving area 30 is provided with a reinforcing plate 40. Of course, the sides 121 of the end cross beam 12 facing the receiving area 30 and the sides 131 of the middle cross beam 13 facing the receiving area 30 may all be provided with a reinforcing plate 40. In the embodiment of the present application, the side 11 of the bottom cross beam 10 facing the receiving area 30 is the vertical side of the bottom cross beam 10. It can be understood that the side 11 of the bottom cross beam 10 facing the receiving area 30 does not include the top surface and the bottom surface of the bottom cross beam 10.

[0050] In the related art, the main body of the prefabricated cabin generally adopts a frame structure. During the lifting and transportation of the prefabricated cabin, the bottom crossbeam supports a large force, so the strength requirement of the bottom crossbeam is particularly important. And prefabricated cabins of different sizes usually have different load-bearing requirements, so the material and size selection of the bottom crossbeam becomes more troublesome. In order to ensure transportation safety, the material and specifications of the bottom crossbeam are often increased (over-design), resulting in excessive increase in the overall weight and cost of the prefabricated cabin.

[0051] Please combine Figure 4According to the load-bearing characteristics of mechanical properties, the deformation of the bottom beam of the prefabricated cabin is larger in the middle (welded and fixed at both ends, hoisted at both ends), and smaller at both ends, so the lateral load demand of the prefabricated cabin is uneven. In order to meet the demand, larger square steel, rectangular steel, etc. are generally used. For example, the bottom beam originally used 100mm*100mm*6mm (inner wall thickness) square steel, which needs to be increased to 150mm*200mm*8mm (inner wall thickness) rectangular steel, resulting in an increase in weight, material, and cost.

[0052] In the energy storage frame 100 of the embodiment of the present application, a reinforcing plate 40 is installed on the inner side of the bottom beam 10 (i.e., the side 11 facing the accommodating area 30). The reinforcing plate 40 is installed on the inner side of the bottom beam 10, which is a tensile surface or a weak portion. The reinforcing plate 40 can form a whole with the bottom beam 10 to bear force together, thereby improving the stress state of the bottom beam 10, thereby improving the bending and shearing resistance of the component and reducing the further development of cracks. The length, height, and thickness dimensions of the reinforcing plate 40 can be adjusted according to actual needs, which can not only strengthen the load strength in the middle of the bottom beam 10, but also will not cause excessive increase in the overall weight and cost, so that the mechanical properties of the material are fully utilized.

[0053] See also Figures 1 to 3 As an optional technical solution of the present application, the plurality of bottom cross beams 10 include two end cross beams 12 arranged opposite to each other, and a middle cross beam 13 arranged between the two end cross beams 12. The two end cross beams 12 are provided with a reinforcing plate 40 on the side 121 facing the accommodating area 30; and / or the middle cross beam 13 is provided with a reinforcing plate 40 on the side 131 facing the accommodating area 30.

[0054] In the above technical solution, by adding reinforcing plates 40 to the end cross beams 12 and / or the middle cross beams 13 , the structural strength of the bottom cross beam 10 can be improved.

[0055] Specifically, the two end beams 12 can be arranged parallel to each other and have the same length. The middle beam 13 is located between the two end beams 12 and is parallel to the two end beams 12. The number of the middle beams 13 can be one or more, and the length relationship between the middle beams 13 and the end beams 12 is not limited. The length of the middle beam 13 can be greater than the end beam 12, or equal to the end beam 12, or less than the end beam 12. For example Figure 3 In the embodiment, the number of the middle cross beam 13 is one, and the length of the middle cross beam 13 is smaller than the end cross beam 12 .

[0056] In the implementation mode of this application, Figure 5 and Figure 6As shown, the side 121 of the two end cross beams 12 facing the receiving area 30 is provided with a reinforcing plate 40; or the side 131 of the middle cross beam 13 facing the receiving area 30 is provided with a reinforcing plate 40; or the side 121 of the two end cross beams 12 facing the receiving area 30 and the side 131 of the middle cross beam 13 facing the receiving area 30 are both provided with a reinforcing plate 40. In this way, the structural strength of the bottom cross beam 10 can be improved.

[0057] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 As an optional technical solution of the present application, the plurality of bottom longitudinal beams 20 include two end longitudinal beams 21 disposed opposite to each other, and a middle longitudinal beam 22 disposed between the two end longitudinal beams 21. When the two end cross beams 12 are provided with reinforcing plates 40 on the side surfaces 121 facing the accommodating area 30, the middle longitudinal beam 22 is connected between the reinforcing plates 40 on the side surfaces 121 of the two end cross beams 12.

[0058] In the above technical solution, by adding a reinforcing plate 40 to the end cross beam 12 and connecting the middle longitudinal beam 22 to the end cross beam 12 through the reinforcing plate 40 , the load strength of the end cross beam 12 can be enhanced.

[0059] Specifically, the two end longitudinal beams 21 can be arranged parallel to each other and have the same length. The middle longitudinal beam 22 is located between the two end longitudinal beams 21 and is parallel to the two end longitudinal beams 21. The number of the middle longitudinal beams 22 can be one or more, and the length relationship between the middle longitudinal beams 22 and the end longitudinal beams 21 is not limited. The length of the middle longitudinal beam 22 can be greater than the end longitudinal beam 21, or equal to the end longitudinal beam 21, or less than the end longitudinal beam 21. For example Figure 3 In the embodiment, the number of the intermediate longitudinal beams 22 is 6, and the length of the intermediate longitudinal beams 22 is equal to the end longitudinal beams 21.

[0060] In the embodiment of the present application, the side 121 of the two end beams 12 facing the accommodating area 30 is provided with a reinforcing plate 40, that is, the inner side surfaces of the two end beams 12 facing each other are provided with a reinforcing plate 40 (such as Figure 5 and Figure 6 During the manufacturing process of the energy storage frame 100, the reinforcing plates 40 are first installed on the inner sides of the two end cross beams 12, and then the two ends of the middle longitudinal beam 22 are respectively connected to the two opposite reinforcing plates 40, so as to achieve the assembly connection between the middle longitudinal beam 22 and the end cross beam 12.

[0061] See also Figure 1 , Figure 2 , Figure 5 and Figure 6As an optional technical solution of the present application, the plurality of bottom longitudinal beams 20 include two end longitudinal beams 21 arranged opposite to each other, and a middle longitudinal beam 22 arranged between the two end longitudinal beams 21. When the middle cross beam 13 is provided with a reinforcing plate 40 on the side 131 facing the accommodating area 30, the middle longitudinal beam 22 is connected between the two end cross beams 12, and the middle cross beam 13 is mounted on the middle longitudinal beam 22.

[0062] In the above technical solution, the middle longitudinal beam 22 is connected to the end cross beam 12 , and the middle cross beam 13 is mounted on the middle longitudinal beam 22 . By adding a reinforcing plate 40 to the middle cross beam 13 , the load strength of the middle cross beam 13 can be improved.

[0063] Specifically, the explanations and descriptions of the end longitudinal beams 21 and the middle longitudinal beams 22 in the aforementioned embodiments are also applicable to the embodiments of the present application and will not be repeated here.

[0064] The difference is that, in the embodiment of the present application, the side 131 of the middle cross beam 13 facing the accommodating area 30 is provided with a reinforcing plate 40. It can be understood that the two opposite side surfaces 131 of the middle cross beam 13 each face the accommodating area 30, and therefore, the two opposite side surfaces 131 of the middle cross beam 13 can be provided with reinforcing plates 40. In the manufacturing process of the energy storage frame 100, the two ends of the middle longitudinal beam 22 are first connected to the two oppositely arranged end cross beams 12, and then the middle cross beam 13 is mounted on the middle longitudinal beam 22, so as to realize the assembly connection between the end cross beams 12, the middle longitudinal beam 22, and the middle cross beam 13.

[0065] See also Figure 1 and Figure 2 As an optional technical solution of the present application, the energy storage frame 100 further includes a plurality of columns 50. The plurality of columns 50 are assembled with a plurality of bottom beams 10 and / or a plurality of bottom longitudinal beams 20. At least part of the columns 50 is supported by the bottom beams 10.

[0066] In the above technical solution, a plurality of bottom cross beams 10, a plurality of bottom longitudinal beams 20, and a plurality of columns 50 are assembled together, and at least part of the columns 50 are supported on the bottom cross beam 10. Since a reinforcing plate 40 is installed on the inner side of the bottom cross beam 10, the structural strength of the bottom cross beam 10 is relatively high, and thus the stability of the overall structure is relatively high.

[0067] Specifically, the plurality of columns 50 may be long columnar structures. The plurality of columns 50 are parallel to each other and may be of equal or unequal lengths. At least some of the columns 50 are supported by the bottom cross beam 10, that is, some or all of the columns 50 are supported by the bottom cross beam 10.

[0068] The assembly relationship between the plurality of upright posts 50 and the plurality of bottom cross beams 10 and the plurality of bottom longitudinal beams 20 can be: the plurality of upright posts 50 are assembled with the plurality of bottom cross beams 10 and the plurality of bottom longitudinal beams 20 at the same time; or, the plurality of upright posts 50 are assembled with the plurality of bottom cross beams 10, and the plurality of bottom cross beams 10 are assembled with the plurality of bottom longitudinal beams 20; or, the plurality of upright posts 50 are assembled with the plurality of bottom longitudinal beams 20, and the plurality of bottom longitudinal beams 20 are assembled with the plurality of bottom longitudinal beams 20.

[0069] See also Figure 1 and Figure 2 As an optional technical solution of the present application, the length extension direction of the plurality of bottom cross beams 10 is a first direction (eg Figure 1 X direction), the length extension direction of the plurality of bottom longitudinal beams 20 is the second direction (such as Figure 1 The length of the plurality of columns 50 extends in a third direction (eg Figure 1 The first direction, the second direction, and the third direction are perpendicular to each other.

[0070] In the above technical solution, a plurality of bottom cross beams 10, a plurality of bottom longitudinal beams 20, and a plurality of columns 50 are assembled into a three-dimensional frame structure. The overall structure is easy to manufacture and has high stability.

[0071] See also Figure 1 and Figure 2 As an optional technical solution of the present application, the connection method between the reinforcing plate 40 and the bottom cross beam 10 includes any one of welding, bonding or bolting.

[0072] In the above technical solution, the connection method between the reinforcing plate 40 and the bottom cross beam 10 is relatively stable, and the processing technology is simple and fast.

[0073] Specifically, the connection mode of the reinforcing plate 40 and the bottom cross beam 10 may specifically refer to: the connection mode of the reinforcing plate 40 and the end cross beam 12, and the connection mode of the reinforcing plate 40 and the middle cross beam 13. That is to say, when the two end cross beams 12 are provided with reinforcing plates 40 on the side 121 facing the accommodation area 30, the reinforcing plates 40 are connected to the side 121 of the end cross beam 12 facing the accommodation area 30 by any one of welding, bonding or bolting. When the middle cross beam 13 is provided with reinforcing plates 40 on the side 131 facing the accommodation area 30, the reinforcing plates 40 are connected to the side 131 of the middle cross beam 13 facing the accommodation area 30 by any one of welding, bonding or bolting. The welding mode may be spot welding or full welding, and the welding process may be arc welding, which is not limited here.

[0074] See also Figure 1 As an optional technical solution of the present application, the reinforcing plate 40 is a steel plate.

[0075] In the above technical solution, a steel plate is used as the reinforcing plate 40. The steel plate has high tensile strength. The steel plate is installed on the inner side of the bottom cross beam 10, which is a tensile surface or a weak part. The steel plate can form a whole with the bottom cross beam 10 to bear the force together, thereby improving the stress state of the bottom cross beam 10, improving the bending and shearing resistance of the component (the reinforcement effect is better than increasing the cross beam section), reducing the effect of continued development of cracks, and greatly improving the bearing capacity and seismic resistance. In addition, by bonding the steel plate as the reinforcing plate 40 for reinforcement, the reinforced model beam has relatively superior ductility, the effect of improving the bearing capacity is reliable, and the construction is simple and fast, the space occupied is small, the processing cycle is short, and the material consumption is small. After reinforcement, the strength, rigidity and stability of the structure can be significantly improved, and the cross-sectional size and weight of the reinforced component are basically not increased.

[0076] See also Figure 1 As an optional technical solution of the present application, the bottom cross beam 10 is any one of square steel, rectangular steel, channel steel, H-shaped steel or I-shaped steel.

[0077] In the above technical solution, the bottom cross beam 10 is made of square steel, rectangular steel (such as Figure 7 As shown, the height is increased on the basis of square steel and the width is appropriately narrowed. Since the bottom cross beam 10 is mainly stressed in the height direction, the use of rectangular steel can increase the height in the load direction, so that the lateral shear stress is small), any one of channel steel, H-shaped steel or I-shaped steel, these types of bottom cross beams 10 can be suitable for adding reinforcement plates 40, and the application range is wide. In particular, for the frame structure of the bottom cross beam 10 using square steel, by bonding steel plates as reinforcement plates 40 for reinforcement, the speed is fast and the overall effect is good, which can greatly improve the bearing capacity and earthquake resistance of the original structure and components.

[0078] See also Figure 8 As an optional technical solution of the present application, the projection area of ​​the reinforcing plate 40 on the side surface 11 is smaller than the surface area of ​​the side surface 11 .

[0079] In the above technical solution, the projection area of ​​the reinforcing plate 40 on the side 11 is smaller than the surface area of ​​the side 11 , which can, on the one hand, strengthen the structural strength of the bottom cross beam 10 , and on the other hand, avoid interference between the reinforcing plate 40 and the original structure and connection relationship of the bottom cross beam 10 .

[0091] See also Figure 1 and Figure 2 In a second aspect, the present application provides an energy storage device. The energy storage device includes an energy storage frame 100 of any of the above embodiments. The energy storage device may be a prefabricated cabin or container for installing a battery module.

[0092] In the energy storage device of the embodiment of the present application, a reinforcing plate 40 is installed on the inner side of the bottom cross beam 10. The reinforcing plate 40 can form a whole with the bottom cross beam 10 to bear force together, thereby strengthening the structural strength of the bottom cross beam 10, greatly improving the bearing capacity and earthquake resistance, and will not cause excessive increase in the overall weight and cost.

[0093] In summary, the energy storage frame 100 and the energy storage device of the embodiment of the present application have at least the following advantages:

[0094] First, the bottom cross beam 10 adopts a square steel frame structure, and is reinforced by bonding a steel plate as a reinforcing plate 40, which is fast and has a good overall effect, and can greatly improve the bearing capacity and earthquake resistance of the original structure and components.

[0095] Second, a steel plate is used as the reinforcing plate 40. The steel plate has high tensile strength. The steel plate is installed on the inner tensile surface or weak position of the bottom cross beam 10. The steel plate and the bottom cross beam 10 can form a whole to bear the force together, thereby improving the stress state of the bottom cross beam 10 and improving the bending and shearing resistance of the component (the reinforcement effect is better than increasing the cross section of the beam).

[0096] Third, by bonding steel plates as the reinforcing plates 40 for reinforcement, the reinforced model beam has relatively superior ductility and a reliable effect of improving the bearing capacity.

[0097] Fourth, by bonding steel plates as reinforcing plates 40 for reinforcement, the construction is simple and quick, the space occupied is small, the processing cycle is short, and the material consumption is small. After reinforcement, the strength, rigidity and stability of the structure can be significantly improved, and the cross-sectional size and weight of the reinforced components are basically not increased.

[0098] Fifth, in response to different load requirements, with the same bottom cross beam 10 as the base material, the length, height, and thickness dimensions of the reinforcing plate 40 can be adjusted according to actual needs and flexibly adjusted.
