Description

Technical Field

[0001] The invention belongs to the field of composite material wall panel design, and in particular relates to a reinforced wall panel. Background Art

[0002] Reinforced siding is a commonly used structural form in the design of composite siding. Its structural form has excellent bearing capacity, especially when facing compressive loads, its structural efficiency is particularly outstanding. Therefore, this structural configuration is widely used in the design of composite siding.

[0003] Common reinforced wall panels use single-wall panels, including hat-shaped long girders (ribs) arranged in the radial direction to carry radial loads, and frames arranged in the circumferential direction to carry circumferential loads. When in the hyperbolic section, both the circumferential and radial directions are curved surfaces. When facing radial loads, the reinforced wall panels receive pressure from out-of-plane loads, and torque is generated between the load direction and the wall panels, which reduces the structural stability of the reinforced wall panels. Therefore, a new composite wall panel needs to be used in the hyperbolic section to replace the traditional single-wall reinforced wall panel to improve the structural stability of the hyperbolic section. Summary of the invention

[0004] In order to improve the structural stability of the composite wall panel of the double-curved section, the present application provides a reinforced wall panel.

[0005] The present application provides a reinforced wall panel, which adopts the following technical solution: A stiffened wall panel comprises a first skin and a second skin, wherein a first long girder is arranged on the top of the first skin, and a second long girder is arranged on the top of the second skin, and the first skin is connected to the bottom of the second skin through the first long girder so that the first long girder and the second long girder are staggered.

[0006] By adopting the above technical solution, the first skin and the first long stringer constitute the first wall panel layer, and the second skin and the second long stringer constitute the second wall panel layer. In this case, the first wall panel layer and the second wall panel layer are superimposed and connected, so that the reinforced wall panel has two wall panel layers, which can withstand greater out-of-plane loads in the thickness direction, and the structural stability is improved. In addition, the long stringers are staggered, and the load-bearing materials can be arranged more evenly in a limited space, so that the stress caused by the out-of-plane load is evenly transferred to the two wall panel layers, and the structural stability is further improved.

[0007] Optionally, the first skin is bonded to the first long stringer, the second skin is bonded to the second long stringer, the top of the first long stringer is bonded to the bottom of the second skin, and the top of the first long stringer fits with the bottom of the second skin.

[0008] By adopting the above technical solution, the first skin and the first long stringer are glued to form the first wall panel layer, the second skin and the second long stringer are glued to form the second wall panel layer, and the top of the first long stringer is glued to the bottom of the second skin, so as to achieve the position fixation between the first wall panel layer and the second wall panel layer, and avoid the collision between the first wall panel layer and the second wall panel layer when the external force is applied by the out-of-plane load, resulting in unnecessary loss. In addition, the shape of the top of the first long stringer is in line with the bottom of the second skin, so as to ensure that the first long stringer can stably bond the second skin.

[0009] Optionally, both the first long stringer and the second long stringer are hat-shaped long stringers containing cavities, and the cavities are filled with rubber.

[0010] By adopting the above technical solution, the first long stringer and the second long stringer can have multiple shapes such as ladder-shaped long stringer, A-shaped long stringer, Ω-shaped long stringer, etc. On the basis of the hat-shaped long stringer, this case fills rubber in the cavity and utilizes the buffering performance of rubber to greatly improve the local stability of the first long stringer and the second long stringer under the action of compression load.

[0011] Optionally, the first long stringers are distributed at equal intervals on the first skin, and the second long stringers are distributed at equal intervals on the second skin.

[0012] By adopting the above technical solution, the position distribution of the first long girder and the second long girder is set according to the required structural strength, and an equidistant distribution method is usually adopted to evenly distribute the pressure applied by the out-of-plane load to ensure the overall structural strength.

[0013] Optionally, it further includes a connecting member, the connecting member having a first transverse connecting strip, a second transverse connecting strip and longitudinal ribs, the first transverse connecting strip having a first end, a second end and a first fixed end, the second transverse connecting strip having a third end, a fourth end and a second fixed end, the first fixed end and the second fixed end being fixedly connected to the longitudinal ribs; The first end and the second end are connected to the same first skin, and the third end and the fourth end are connected to different second skins; or, The first end and the second end are connected to different first skins, and the third end and the fourth end are connected to the same second skin.

[0014] By adopting the above technical scheme, the first skin and the first long girder constitute the first wall panel layer, and the second skin and the second long girder constitute the second wall panel layer. In the case where the length of the first wall panel layer or the second wall panel layer is insufficient, this case supports the continuation of the first wall panel layer or the second wall panel layer through connecting parts, thereby realizing the reinforced wall panel of this case based on the skin with limited length. This case also facilitates the replacement of damaged and defective first skin and second skin, thereby improving the efficiency of fault repair.

[0015] Optionally, the first end and the second end are connected to different first skins, and the third end and the fourth end are connected to different second skins.

[0016] By adopting the above technical solution, different first skins are connected through the first end and the second end, and different second skins are connected through the third end and the fourth end. Therefore, this case not only supports the connection of a single first skin or a second skin, but also supports the simultaneous connection of the first skin and the second skin.

[0017] Optionally, one end of the longitudinal rib is fixedly connected to the first fixed end of the first transverse connecting strip, and the other end of the longitudinal rib extends from the second transverse connecting strip, and the extending length is less than the height of the second long beam.

[0018] By adopting the above technical solution, the "earth" type connecting piece composed of the first transverse connecting strip, the second transverse connecting strip and the longitudinal vertical ribs is used as an important component for connecting the first skins, the second skins, and the first skins and the second skins at the same time.

[0019] Optionally, the spacing between the first long girders, the spacing between the second long girders, and the spacing between the first long girders and the second long girders are all related to structural stress, and the length of the longitudinal vertical reinforcement extending out of the second transverse connecting strip is related to a preset structural strength requirement.

[0020] By adopting the above technical solution, in order to ensure the structural stability of the integrally reinforced wall panel, the distribution of the first long girder and the second long girder complies with the structural design principle to ensure the structural stability when subjected to external force applied by the out-of-plane load.

[0021] Optionally, the first wall panel layer formed by the first skin and the first long girder is an integral structure, the second wall panel layer formed by the second skin and the second long girder is an integral structure, the connecting piece formed by the first transverse connecting strip, the second transverse connecting strip and the longitudinal vertical rib is an integral metal structure, one free end of the longitudinal vertical rib terminates at the first transverse connecting strip, and the other free end of the longitudinal vertical rib does not exceed the cap top of the second long girder.

[0022] By adopting the above technical solution, the first wall panel layer and the second wall panel layer tend to be set as an integrated structure to ensure the structural stability of the first wall panel layer and the second wall panel layer. The connecting piece is set as an integrated structure to ensure the structural stability of the connecting piece itself, and the connecting piece can better connect the first skin and the second skin.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. This case adopts a double-walled plate layer or even a multi-walled plate layer structure. The load-bearing structure formed in the thickness direction greatly improves the structural stability under the out-of-plane load. The staggered long truss arrangement can arrange the load-bearing materials more evenly in a limited space. It effectively improves the load-bearing capacity of the reinforced wall panels of the hyperbolic section to the out-of-plane load and improves the structural stability.

[0024] 2. Compared with the hollow structure of the long stringer, this case fills the long stringer with rubber to improve the local stability of the long stringer under the action of compression load.

[0025] 3. Compared with the "T"-shaped connector, the "earth"-shaped connector in this case can effectively bear the out-of-plane load and complete the connection of the middle skin of the wall panel. The connector is made of metal material in one piece and is a profile processed from a whole piece of metal, which ensures the structural stability of the connector itself and enables the connector to better connect the first skin and the second skin.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0028] Regarding the problems existing in the prior art, refer to Figure 1 As shown, conventional composite panels are usually configured as single-wall panels, each of which is composed of a skin and a long stringer. Figure 1 The load in the direction shown is not significantly affected by the load because the conventional composite wall panel can be approximated as a plane in the circumferential direction. Figure 1 The load in the direction shown will generate a moment between the load direction and the composite wall panel, which will greatly reduce the stability of the structure and easily lead to structural failure of the composite wall panel. Figure 2 As shown, the composite wall panel is configured as a reinforced wall panel of a single wall layer, and the single wall layer includes a skin and a long stringer, and the skin and the long stringer are glued together. In order to ensure the lightweight of the composite wall panel structure, the long stringer is designed to be hollow.

[0029] The present invention provides a reinforced wall panel, referring to Figure 3 As shown, it includes a first skin 11 and a second skin 21. A first long stringer 12 is arranged on the top of the first skin 11, and a second long stringer 22 is arranged on the top of the second skin 21. The first skin 11 is bonded to the first long stringer 12, and the second skin 21 is bonded to the second long stringer 22. The first skin 11 is connected to the bottom of the second skin 21 through the first long stringer 12, so that the first long stringer 12 and the second long stringer 22 are staggered.

[0030] The first skin 11 and the first long stringer 12 constitute the first wall panel layer 10, and the second skin 21 and the second long stringer 22 constitute the second wall panel layer 20. The first wall panel layer 10 and the second wall panel layer 20 are superimposed and connected, so that the reinforced wall panel has at least two wall panel layers, which can withstand a larger out-of-plane load in the thickness direction, and the structural stability is improved. In addition, the first long stringer 12 and the second long stringer 22 are staggered, so that the load-bearing materials can be arranged more evenly in a limited space, so that the stress caused by the out-of-plane load is evenly transferred to the first wall panel layer 10 and the second wall panel layer 20, and the structural stability is further improved.

[0031] In one embodiment, reference Figure 4 As shown, the top of the first long stringer 12 is bonded to the bottom of the second skin 21, and the top of the first long stringer 12 is matched with the bottom of the second skin 21. The top of the first long stringer 12 is bonded to the bottom of the second skin 21 to achieve the position fixation between the first wall panel layer 10 and the second wall panel layer 20, avoiding the collision of the first wall panel layer 10 and the second wall panel layer 20 when the external force is applied by the out-of-plane load, resulting in unnecessary loss. In addition, the shape of the top of the first long stringer 12 is matched with the bottom of the second skin 21, so as to ensure that the first long stringer 12 can be stably bonded to the second skin 21.

[0032] In one embodiment, reference Figure 3 The reinforced wall panel is composed of two wall panel layers, a first wall panel layer 10 and a second wall panel layer 20.

[0033] In another embodiment, reference Figure 5 As shown, the stiffened wall panel is composed of a plurality of wall panel layers, a first wall panel layer 10 and a plurality of second wall panel layers 20, and the direction from the first wall panel layer 10 to the second wall panel layer 20 is from outside to inside. The top of the first long stringer 12 of the first wall panel layer 10 is connected to the second skin 21 of the outermost second wall panel layer 20, and the second long stringer 22 of the outer second wall panel layer 20 is connected to the second skin 21 of the inner second wall panel layer 20, so as to realize the multi-layer design of the integral stiffened wall panel.

[0034] In one embodiment, the spacing between the first long stringers 12 , the spacing between the second long stringers 22 , and the spacing between the first long stringers 12 and the second long stringers 22 are all related to the structural stress.

[0035] The following is the principle of spacing setting: S1, calculate the stiffness matrix and skin ply parameters of the known ply information through the laminate theory; S2, the bending stiffness parameters of the long stringers are obtained through the skin layer parameters and the preliminary long stringer spacing; S3, the tensile stiffness ratio parameter of the long stringer and the skin is obtained by the skin layer parameters; S4, calculates the ratio of the long stringer tensile stiffness to the skin tensile stiffness through the skin layup parameters and the skin tensile stiffness ratio parameters to ensure that it is within a preset safety range.

[0036] S5, through the bending stiffness parameters of the long stringers and the stiffness matrix of the skin, combined with the simulation of the preset stiffness planning of the stiffened wall panels, the necessary stiffness requirements of each first wall panel layer and the second wall panel layer are obtained, and then by continuously adjusting the long stringer spacing values ​​in S2, the spacing between the long stringers in each first wall panel layer and the second wall panel layer is obtained, that is, the spacing between the first long stringers, the spacing between the second long stringers, and the self-inspection spacing between the first long stringers and the second long stringers.

[0037] Therefore, in this embodiment, in order to ensure the structural stability of the integrally reinforced wall panel, the distribution of the first long stringer and the second long stringer follows the structural design principle to ensure the structural stability when subjected to external forces applied by the out-of-plane load.

[0038] In another example, the first long stringers 12 are evenly distributed on the first skin 11, and the second long stringers 22 are evenly distributed on the second skin 21. The evenly distributed second long stringers 22 enable the pressure to be evenly distributed to various positions of the first skin 11 when an out-of-plane load applies an external force, and is transmitted to the second skin 21 through the evenly distributed second long stringers 22.

[0039] In one example, the first long stringer 12 and the second long stringer 22 are both hat-shaped long strings with cavities, Figure 6 This long stringer includes a shell 3 with a thickness, a cavity is arranged inside the shell, and the cavity is filled with a rubber block 4, and the shell is Ω-shaped. In this example, the shell 3 can have multiple shapes such as trapezoidal, A-shaped, square, Ω-shaped, etc. Preferably, it is an Ω-shaped shell 3 with better load-bearing capacity, and rubber is injected into the cavity inside the shell 3, so that the cavity is filled with rubber blocks 4 formed by rubber condensation, and the buffering performance of the rubber is utilized to greatly improve the local stability of the first long stringer 12 and the second long stringer 22 under the action of the compression load.

[0040] In one example, reference Figure 7 and Figure 8 As shown, the stiffened wall panel also includes a connecting member 5, the connecting member 5 has a first transverse connecting strip 51, a second transverse connecting strip 52 and a longitudinal rib 53, the first transverse connecting strip 51 has a first end, a second end and a first fixed end, the second transverse connecting strip 52 has a third end, a fourth end and a second fixed end, and the first fixed end and the second fixed end are fixedly connected to the longitudinal rib 53. The number of the second transverse connecting strips 52 corresponds to the number of the second skins 21, that is, with reference to Figure 7 As shown, there are two second wall panels 20, and the second transverse connecting strip 52 will also have two, refer to Figure 8As shown, there are three second wall panels 20, and there will also be three second transverse connecting strips.

[0041] Take the reinforced wall panel having only one first wall panel layer 10 and one second wall panel layer 20 as an example: When the first skin 11 needs to be connected, the first end and the second end are connected to different first skins 11, and the third end and the fourth end are connected to the same second skin 21. Fig. 9 As shown, the first wall panel layer 10 can be connected by the connecting member 5, and when the length of the first wall panel layer 10 is limited, the reinforced wall panel of the case can be realized by the connecting operation. In addition, when the connecting member 5 is used to connect the first skin 11 and the second skin 21, the first transverse connecting strip 51 is placed on the inner side of the first skin 51, and the first end of the first transverse connecting strip 51 is connected to the first skin 11 on the left side, the second end of the first transverse connecting strip is connected to the skin 11 on the right side, the third end of the second transverse connecting strip 52 is connected to the outer side of the second skin 21, and the fourth end of the second transverse connecting strip 52 is connected to the outer side of the second skin 52. Since the first transverse connecting strip 51 and the first skin 21 are connected in a detachable manner, the case is also convenient for replacing the damaged or defective first skin 11, thereby improving the efficiency of fault repair.

[0042] When the second skin 21 needs to be connected, the first end and the second end are connected to the same first skin 11, and the third end and the fourth end are connected to different second skins 21. Fig.10 As shown, the second wall panel layer 20 can be connected by the connecting member 5, so as to realize the reinforced wall panel of this case according to the skin with limited length. When the connecting member 5 is used to connect the first skin 11 and the second skin 21, the first transverse connecting strip 51 is placed on the inner side of the first skin 51, and the first end and the second end of the first transverse connecting strip 51 are connected to the second skin 21 by screws, bolts and other tools, and the second transverse connecting strip 52 is connected to the second skin 21 on the left side through the third end, and the second transverse connecting strip 52 is connected to the second skin 21 on the right side through the fourth end. Since the second transverse connecting strip 52 and the second skin 21 are connected in a detachable manner, it is convenient to replace the damaged or defective second skin 21, thereby improving the efficiency of fault repair.

[0043] When the first skin 11 and the second skin 21 need to be connected at the same time, the first end and the second end are connected to different first skins 11, and the third end and the fourth end are connected to different second skins 21. Figure 7As shown, using tools such as screws, bolts, etc., the first transverse connecting strip 51 is connected to the first skin 11 on the left side through the first end, and is connected to the second skin 12 on the right side through the second end, the second transverse connecting strip 52 is connected to the second skin 21 on the left side through the third end, and the second transverse connecting strip 52 is connected to the second skin 21 on the right side through the fourth end. In this example, the first wall panel layer 10 and the second wall panel layer 20 are connected through the connector 5, so as to realize the reinforced wall panel of this case according to the skin with limited length, and this case is also convenient for replacing the damaged and defective first skin 11 and second skin 21, so as to improve the efficiency of fault repair.

[0044] In some examples, reference Figure 7 and Fig.11 As shown, one end of the longitudinal rib 53 is fixedly connected to the first fixed end of the first transverse connecting strip 51, and the outer free end of the longitudinal rib 53 is terminated at the first transverse connecting strip 51; the other end of the longitudinal rib 53 extends from the second transverse connecting strip 52, and the length of the longitudinal rib 53 extending out of the outermost second transverse connecting strip 52 is less than the height of the innermost second long girder 22, that is, the inner free end of the longitudinal rib 53 does not exceed the cap top of the innermost second long girder 22.

[0045] The outer free end of the longitudinal rib 53 can be arranged on one side of the first transverse connecting strip 51, can be arranged on the upper surface of the first transverse connecting strip 51, can be sleeved in the through hole in the middle of the first transverse connecting strip 51, can be embedded in the limit groove in the middle of the first transverse connecting strip 51, etc. The outer free end of the longitudinal rib 53 terminates at the first transverse connecting strip 51 to ensure that no bulge appears on the plane where the first skin 11 and the second skin 21 connected to each other by the connector 5 are located. When an out-of-plane load applies an external force, the longitudinal rib 53 is prevented from destroying the integrally reinforced wall panel. It is worth mentioning that the length of the longitudinal rib 53 extending out of the innermost second transverse connecting strip 52 is related to the preset structural strength requirement of the integrally reinforced wall panel in this case, so as to ensure the stability of the structure when subjected to external forces applied by the out-of-plane load.

[0046] In some examples, the first wall panel layer 10 composed of the first skin 11 and the first long stringer 12 is an integrated structure, the second wall panel layer 20 composed of the second skin 21 and the second long stringer 22 is an integrated structure, and the connector 5 composed of the first transverse connecting strip 51, the second transverse connecting strip 52 and the longitudinal rib 53 is an integrated metal structure. In other words, the first wall panel layer 10, the second wall panel layer 20 and the connector 5 can all be manufactured by one-piece molding, and are made of metal materials in one piece, and are profiles processed from a whole piece of metal to ensure the structural stability of the first wall panel layer 10 and the second wall panel layer 20. The connector is set as an integrated structure to ensure the structural stability of the connector itself, and the connector 5 can better connect the first skin 11 and the second skin 21.

[0047] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims.
