Description

Technical Field

[0001] This invention relates to the field of composite material manufacturing technology, and more specifically, to a positioning device and method for forming high-density multi-ribbed composite wall panels. Background Technology

[0002] Composite material stiffened panel structures are widely used in aircraft structures such as fuselages, wings, vertical tails, and cabin doors due to their good strength, stiffness, and design flexibility. The structural components of stiffened panels are mainly skin and stiffeners. The stiffeners are all high slenderness ratio structures, also known as stringers or longitudinal walls. According to the cross-sectional shape of the stiffeners, common types include "L", "J", "T", "I", and "C" shapes. The main molding methods include: ① mechanical connection after the stiffeners and skin are cured; ② secondary adhesive bonding after the stiffeners and skin are cured; ③ co-bonding, where the stiffeners are cured first and then bonded to the uncured skin while curing, or vice versa; ④ co-curing, where the skin and stiffeners are laid out separately but not cured individually, and instead cured together. Except for the first method, where the positional relationship between the reinforcing rib and the skin is ensured by subsequent mechanical connection, the other three methods, whether it is secondary bonding, co-bonding, or co-curing, all require a reasonable positioning method for the stringer design to ensure the relative positional relationship between the stringers and between the stringers and the skin.

[0003] Typically, when the number of stringers in a panel is small and the span is not large, the stiffened panel is positioned on the stringers using positioning blocks at both ends combined with a positioning beam in the middle. Each stringer is positioned on the crossbeam while being assembled with the skin edge. However, for panel structures with a large number of stringers and high density, if the conventional crossbeam positioning method is used, assembling each stringer separately on the skin and then positioning each stringer individually with each crossbeam, the operation space is limited. Performing the same operation on numerous stringers on the skin is time-consuming and laborious, and it is easy to damage the skin. This is especially true for panel structures with larger spans, where it is even more difficult to achieve the cumbersome assembly and positioning of stringers with the skin and crossbeams. Summary of the Invention

[0004] (a) Technical problems to be solved The technical problem to be solved by this invention is that for wall panel structures with a large number of stringers and high density, the existing positioning methods are time-consuming and labor-intensive, and are prone to damaging the skin. This is especially true for wall panels with large spans, where it is even more difficult to achieve the cumbersome assembly and positioning of stringers with skin and beams.

[0010] Preferably, the support includes a first longitudinal beam, a second longitudinal beam, and multiple crossbeams. The first and second longitudinal beams are arranged along the length of the precast truss body. One end of each crossbeam is connected to the first longitudinal beam, and the other end of each crossbeam is connected to the second longitudinal beam. Multiple crossbeams are spaced apart along the length of the first longitudinal beam. Multiple limiting components are connected to the crossbeams, and adjacent limiting components are arranged at a preset distance along the length of the crossbeams.

[0011] Preferably, the system further includes a reinforcing beam, one end of which is connected to and fixed to the first longitudinal beam, and the other end of which is connected to and fixed to the second longitudinal beam.

[0012] Preferably, the bracket further includes positioning blocks and positioning pins, with the positioning blocks provided at both ends of the first longitudinal beam and / or the second longitudinal beam, and the positioning pins positioningly connecting the positioning blocks to the first longitudinal beam / second longitudinal beam.

[0013] Preferably, the system further includes a plurality of pads, which are spaced apart along the length of the first longitudinal beam / second longitudinal beam.

[0026] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0027] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be located directly on or indirectly on the other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to the other component.

[0028] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate that the device or element must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating relative importance or the number of technical features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this invention will be described in more detail below with reference to specific embodiments: like Figures 1 to 5 As shown, this embodiment of the invention provides a positioning device for forming a high-density multi-ribbed composite wall panel, used to position and install a precast stringer A with a preset positioning surface A1 on a precast skin B. The positioning device includes an outer mold 1 and a positioning frame 2. The outer mold 1 is used to place the precast skin B. The positioning frame 2 includes a support 21 and multiple limiting components 22. The support 21 is connected to the outer mold 1, and the multiple limiting components 22 are connected to the support 21. Adjacent limiting components 22 are arranged at a preset distance. The limiting components 22 have a positioning surface 221, which matches and connects with the preset positioning surface A1 so that adjacent precast stringers A maintain a preset distance.

[0030] In one embodiment, the precast stringer A is a solidified precast stringer. The limiting component 22 includes a first limiter 222. The solidified precast stringer has a preset positioning surface A1, which is a web surface. The first limiter 222 has a positioning surface 221, which abuts against the web surface. For the solidified precast stringer A, the shape of the precast stringer A is basically stable. The first limiter 222 can directly position the web of the precast stringer A. When the cross-sectional shape of the stringer is symmetrical, one side of the web surface is selected as the preset positioning surface A1 for positioning. Figure 1 As shown, when the precast stringer A is a "T"-shaped stringer, one side of the "T"-shaped stringer can be used as a preset positioning surface A1. When the precast stringer A is an "I"-shaped stringer, one side of the "I"-shaped stringer can be used as a preset positioning surface A1. The preset positioning surface A1 cooperates with the positioning surface 221 of the first limiter 222 (specifically the first limiter surface 2221) for positioning. When the cross-sectional shape of the precast stringer A is asymmetrical, the web surface with the flange is selected as the positioning surface. For example, when the precast stringer A is a "J"-shaped stringer or a "C"-shaped stringer, the inner web surface of the "J"-shaped stringer or "C"-shaped stringer is selected as the preset positioning surface A1. The preset positioning surface A1 cooperates with the positioning surface 221 of the first limiter 222 for positioning. The cross-sectional shape and size of the first limiter 222 vary according to the shape of the specific preset positioning surface A1. The gap between the positioning surface 221 of the first limiter 222 and the preset positioning surface A1 is selected according to the thickness of the auxiliary materials (such as vacuum bags, breathable felt, etc.) used between the two during molding, and is required to be 0~0.2mm. The gap between the second limiting surface 2222 of the first limiter 222 and the inner surface of the upper flange of the stringer precast body A is required to be no less than the upper deviation value of the cumulative thickness of the lower flange of the skin precast body B and the stringer precast body A, with a tolerance range of 0~1mm.

[0031] In one embodiment, the limiting component 22 includes a first limiter 222 and a stringer positioning mold 223. The stringer positioning mold 223 has a positioning surface 221 adapted to a preset positioning surface A1 of the corresponding stringer precast body A. The preset positioning surface A1 abuts against the positioning surface 221. The first limiter 222 is connected to the positioning frame 2 and the stringer positioning mold 223. Specifically, the first limiting surface 2221 of the first limiter 222 positions the stringer precast body A through the outer surface of the stringer positioning mold 223. The stringer positioning mold 223 and the first limiter 222 are connected and fixed by screws 3. Several typical positional relationships between the stringer precast body A with the stringer positioning mold 223 and the first limiter 222 are shown below. Figure 2 As shown. No auxiliary material is used between the first limiting surface 2221 of the first limiter 222 and the positioning surface (preset positioning surface A1) of the stringer positioning mold 223.

[0032] In one embodiment, the limiting component 22 includes a first limiter 222 and a second limiter 224. The first limiter 222 is connected to the bracket 21, and the second limiter 224 is connected to the first limiter 222. A cavity is formed between the first limiter 222 and the second limiter 224. The cavity has a positioning surface 221, and the positioning surface 221 is matched and connected with a preset positioning surface.

[0033] In one embodiment, the limiting component 22 includes a first limiter 222, a second limiter 224, and a stringer positioning mold 223. The first limiter 222 is connected to the bracket 21, the second limiter 224 is connected to the first limiter 222, and the stringer positioning mold 223 is connected to the first limiter 222. A cavity is formed between the first limiter 222, the second limiter 224, and the stringer positioning mold 223. The cavity has a positioning surface 221, which is matched and connected with a preset positioning surface A1.

[0034] In another embodiment, the limiting component 22 further includes a stringer auxiliary mold 225, which is disposed between the second limiter 224 and the stringer precast body A. The second limiter 224 is disposed opposite to the first limiter 222, and screws 3 fasten the second limiter 224 and the first limiter 222 together, providing height-direction limiting and clamping effect on the position of the stringer precast body A when the stringer precast body A, the stringer positioning mold 223, and the stringer auxiliary mold 225 are assembled with the bracket 21. A gap of 0-1mm is reserved between the third limiting surface 2241 of the second limiter 224 and the web surface on the same side of the stringer precast body A (or the outer surface of the stringer auxiliary mold 225). The gap between the fourth limiting surface 2242 of the second limiter 224 and the top surface of the precast stringer A (or the top surface of the precast stringer A, the precast stringer positioning mold 223, and the precast stringer auxiliary mold 225 assembly) is selected according to the thickness of the auxiliary material used between them, generally requiring 0~0.2mm. The cross-sectional shape and dimensions of the second limiter 224 vary depending on the specific cross-section of the precast stringer A. Several typical cross-sectional shapes of the second limiter 224 and their positional relationship with the first limiter 222 are as follows: Figure 4 As shown.

[0035] In one embodiment, the support 21 includes a first longitudinal beam 211, a second longitudinal beam 212, and multiple crossbeams 213. The first and second longitudinal beams 211 and 212 are arranged along the length of the precast truss A. One end of each crossbeam 213 is connected to the first longitudinal beam 211, and the other end is connected to the second longitudinal beam 212. The multiple crossbeams 213 are spaced apart along the length of the first longitudinal beam 211. Multiple limiting components 22 are connected to the crossbeams 213, and adjacent limiting components 22 are arranged at a preset distance along the length of the crossbeams 213. The dimensions of the first and second longitudinal beams 211 and 212 in the length direction meet the positioning and fixing requirements of the crossbeams 213 at both ends. The overall width of the bracket 21 is determined according to the width of the outer mold 1. Crossbeams 213 are provided at the ends of both the first longitudinal beam 211 and the second longitudinal beam 212 for connection and fixation. Several crossbeams 213 are provided in the middle area of ​​the first longitudinal beam 211 and the second longitudinal beam 212, depending on the length of the first longitudinal beam 211 / second longitudinal beam 212 and the positional accuracy requirements of the stringer in the middle area. The spacing between two adjacent crossbeams 213 does not exceed 1200mm. The ends of the crossbeams 213 are flush with the outer sides of the first longitudinal beam 211 and the second longitudinal beam 212. Specifically, to ensure the positional accuracy of the first limiting surface 2221 of the first limiter 222 at each location, during the fabrication of the overall positioning frame 2, after the first longitudinal beam 211, the second longitudinal beam 212, multiple crossbeams 213, and the first limiter 222 are combined and fixed, the first limiting surface 2221 of the first limiter 222 is then uniformly processed.

[0036] In one embodiment, a reinforcing beam 214 is also included. One end of the reinforcing beam 214 is connected to and fixed to the first longitudinal beam 211, and the other end of the reinforcing beam 214 is connected to and fixed to the second longitudinal beam 212. To increase the overall rigidity of the positioning frame, a reinforcing beam 214 can be added between the first longitudinal beam 211 and the second longitudinal beam 212 as needed. The reinforcing beam 214 is welded to and fixed to the first longitudinal beam 211 and the second longitudinal beam 212 by mechanical connection.

[0037] In one embodiment, the bracket 21 further includes positioning blocks 215 and positioning pins 216. Positioning blocks 213 are respectively provided at both ends of the first longitudinal beam and the second longitudinal beam 212, and the positioning pins 216 position and connect the positioning blocks 215 to the first longitudinal beam 211 / second longitudinal beam 212. Specifically, the bracket 21 is positioned by the positioning blocks 215 on both sides of the first longitudinal beam 211 / second longitudinal beam 212. The positioning blocks 215 are located at both ends of the first longitudinal beam 211 / second longitudinal beam 212 and are flush with the ends of the first longitudinal beam 211 / second longitudinal beam 212, and the positioning pins 216 are fixed thereon. Further, pin holes are provided at preset positions of the positioning blocks 215 and the first longitudinal beam 211 / second longitudinal beam 212 so that the positioning pins 216 can pass through for positioning.

[0038] In one embodiment, a plurality of pads 217 are also included, which are spaced apart along the length of the first longitudinal beam 211 / second longitudinal beam 212. The thickness of the pads 217 is equal to the thickness of the positioning block 215, and the pads 217 are used to support and fix the middle area of ​​the first longitudinal beam 211 / second longitudinal beam 212.

[0039] The present invention also provides a positioning method for forming a high-density multi-ribbed composite wall panel, wherein the positioning device for forming a high-density multi-ribbed composite wall panel according to any of the above embodiments is used for positioning, and the positioning method includes the following steps: Multiple precast truss bodies A are fixedly installed on the positioning frame 2. The preset positioning surface A1 of the precast truss body A matches the positioning surface 221 of the connecting limiting component 22 so that two adjacent precast truss bodies A maintain a preset distance, thereby obtaining the rib positioning component. Position the prefabricated skin A on the outer mold 1 to obtain the wall panel positioning assembly; The rib positioning component is positioned and installed on the wall panel positioning component to achieve the positioning and installation of the long truss precast body A on the skin precast body B.

[0040] The specific implementation steps of the positioning method for forming high-density multi-ribbed composite wall panels are as follows: Multiple precast truss sections A are fixedly installed on the positioning frame 2 for pre-positioning to ensure the positional relationship between the multiple precast truss sections A. The specific operation steps are as follows: First, flip the positioning frame 2 so that the first longitudinal beam 211, the second longitudinal beam 212 and multiple transverse beams 213 are at the bottom, and the first limiter 222 and the second limiter 224 are at the top. Assemble and clamp the precast truss sections A (or precast truss section A, truss positioning mold 223 and truss auxiliary mold 225) one by one at the corresponding positions of the overall positioning frame 2. The first limiting surface 2221 of the first limiter 222 limits the truss section A laterally, and the fourth limiting surface 2242 of the second limiter 224 limits the truss section A in the height direction.

[0041] The assembly method of the long string on the overall positioning frame differs depending on whether or not the long string positioning mold 223 is present: For the assembly of the precast stringer A without the stringer positioning mold 223 and the overall positioning frame 2, when assembling each precast stringer A, first loosen the screws 3 between the first limiter 222 and the second limiter 224 corresponding to the precast stringer A, and remove the second limiter 224. Place the precast stringer A at the corresponding stringer position on the positioning frame 2, so that the preset positioning surface A1 fits with the first limiter surface 2221 of the first limiter 222. According to the thickness of the gap reserved between the first limiter surface 2221 of the first limiter 222 and the preset positioning surface A1 of the precast stringer A designed in the positioning frame 2, pad the preset positioning surface A1 of the precast stringer A with auxiliary material of the same thickness between the preset positioning surface A1 of the precast stringer A and the first limiter surface 2221 of the first limiter 222. Position the precast stringer A along its length according to the position of the first limiter 222 at the end of the precast stringer A on the positioning frame 2. Assemble the second limiter 224. The fourth limiting surface 2242 of the second limiter 224 limits the height of the preset positioning surface A1. Based on the gap reserved between the fourth limiting surface 2242 of the second limiter 224 and the top surface of the precast stringer A, place an auxiliary material of equal thickness between the top surface of the precast stringer A and the fourth limiting surface 2242 of the second limiter 224. Place a rubber-like auxiliary material between the precast stringer A and the third limiting surface 2241 of the second limiter 224, with a thickness not less than the thickness of the gap reserved between the third limiting surface 2241 of the second limiter 224 and the web surface on the same side of the precast stringer A. Tighten the screws 3 between the first limiter 222 and the second limiter 224. Alternatively, a clamp can be used to clamp the precast stringer A to the first limiter 222. The clamp must be positioned between the precast stringer A and the crossbeam 213 and must not be placed at the interface between the precast stringer A and the skin precast body B.

[0042] For the assembly of the precast stringer A with the stringer positioning mold 223 and the overall positioning frame 2, first loosen the screws 3 between the first limiter 222 and the second limiter 224. Place the precast stringer A, the stringer positioning mold 223, and the stringer auxiliary mold 225 on the positioning frame 2. Limit the height of the corresponding precast stringer A through the fourth limiting surface 2242 of the second limiter 224. Initially position the length of the precast stringer A according to the position of the first limiter 222 at the end of the precast stringer A corresponding to the positioning frame 2. Connect and fix the first limiter 222 and the stringer positioning mold 223 with screws 3.

[0043] If there is no auxiliary mold 225 for the long stringer, a rubber-like auxiliary material is placed between the long stringer precast body A and the third limiting surface 2241 of the second limiter 224, with a thickness not less than the thickness of the gap reserved between the third limiting surface 2241 of the second limiter 224 and the web surface on the same side of the long stringer precast body A. If there is an auxiliary mold 225 for the long stringer, a rubber-like auxiliary material is placed between the auxiliary mold 225 for the long stringer and the third limiting surface 2241 of the second limiter 224, with a thickness not less than the thickness of the gap reserved between the third limiting surface 2241 of the second limiter 224 and the side surface of the auxiliary mold 225 for the long stringer.

[0044] Next, tighten the screws 3 between the first limiter 222 and the second limiter 224. Alternatively, a clamp can be used to clamp the precast stringer A or the auxiliary stringer mold 225 with the first limiter 222 and the stringer positioning mold 223. The clamp should be placed between the precast stringer A and the crossbeam, and not at the interface between the stringer and the skin.

[0045] After assembling, positioning, and clamping all precast truss bodies A (or precast truss body A, truss positioning mold 223, etc.) with positioning frame 2, the assembled precast truss bodies A (or precast truss body A, truss positioning mold 223, etc.) are flipped together with positioning frame 2 and transferred to the outer mold 1 on which the skin precast body B has been positioned and installed. The first longitudinal beam 211, the second longitudinal beam 212, and the positioning block 215 on the outer mold 1 are positioned by positioning pins 216. After positioning frame 2 and outer mold 1 are positioned, the positioning and installation of all precast truss bodies A on skin precast body B is achieved, ensuring the positional relationship between all precast truss bodies A and skin precast body B on outer mold 1. Positioning frame 2, which has precast truss bodies A and truss positioning mold 223 installed, is positioned on skin precast body B as follows. Figure 1 As shown.

[0046] The present invention will be further described in detail below with reference to specific embodiments. Example 1 In this embodiment, the high-density multi-ribbed composite wall panel to be prepared has a length of 5500mm and a width of 1590mm. This high-density multi-ribbed composite wall panel is composed of a skin prefabricated body B and eight "J"-shaped stringers (stringer prefabricated bodies A) installed on it. The distance between the axial positions of two adjacent stringer prefabricated bodies A is 200mm, and the height of stringer prefabricated bodies A is 120mm. The panel is co-bonded using a prepreg autoclave process. The skin prefabricated body B is cured first, and then combined with the uncured "J"-shaped stringers for co-curing. Based on the structural characteristics and manufacturing process of the "J"-shaped trusses, the positioning devices for the eight "J"-shaped trusses, requiring multi-point positioning, are designed as a rigid integral structure (positioning frame 2). This allows the eight "J"-shaped trusses to be pre-positioned using the positioning frame 2 to ensure their positional relationship. Then, the positioning frame 2 is flipped and transferred onto the outer mold 1. By positioning the integral positioning frame 2 with the outer mold positioning block 215 on the outer mold 1, simultaneous positioning of all truss precast bodies A and skin precast bodies B is achieved. The specific operation method is as follows: The positioning device for forming high-density multi-reinforced composite wall panels provided in this embodiment includes a positioning frame 2, clamps and connectors, lifting rings, etc., as well as related outer mold 1, positioning block 215, pad block 217, stringer positioning mold 223, etc.

[0047] The positioning frame 2 consists of a first longitudinal beam 211, a second longitudinal beam 212, six crossbeams 213, a first limiter 222, and a second limiter 224. The length of the first longitudinal beam 211 and the second longitudinal beam 212 is equal to the length of the precast truss A, and the width of the positioning frame 2 is equal to the width of the outer mold 1. Crossbeams 213 are installed and fixed at the ends of the first longitudinal beam 211 and the second longitudinal beam 212. Four crossbeams 213 are arranged in the middle area of ​​the first longitudinal beam 211 and the second longitudinal beam 212 at intervals not exceeding 1200mm. The ends of the crossbeams 213 are flush with the outer sides of the first longitudinal beam 211 and the second longitudinal beam 212. The two ends of the crossbeams 213 are positioned with the first longitudinal beam 211 / the second longitudinal beam 212 by pins and fixed above the first longitudinal beam 211 / the second longitudinal beam 212 by screws. To increase the rigidity of the positioning frame 2, two reinforcing beams 214 are added between the first longitudinal beam 211 and the second longitudinal beam 212, and the reinforcing beams 214 are welded and fixed to the first longitudinal beam 211 and the second longitudinal beam 212.

[0048] The positioning frame 2 is positioned on positioning blocks 215 fixed to both sides of the outer mold 1 by means of the first longitudinal beam 211 and the second longitudinal beam 212. The positioning blocks 215 are located at both ends of the first longitudinal beam 211 and the second longitudinal beam 212 and are flush with the ends of the first longitudinal beam 211 and the second longitudinal beam 212. Positioning pins 216 are fixed on them. In addition, two pads 217 fixed to the outer mold 1 are provided between the lower surface of the middle area of ​​the first longitudinal beam 211 / second longitudinal beam 212 and the outer mold 1.

[0049] The first limiter 222 is located between the stringer positioning mold 223 and the crossbeam 213, and is used to position the stringer precast body A. The first limiters 222 are installed between the 6 crossbeams 213 and the 8 stringer precast bodies A, totaling 48. The cross-section of the first limiter 222 is designed as an "L" shape. The upper edge of the "L" shape mates with the crossbeam 213, and the connection is designed to be detachable, using crossbeam pins 2131 for positioning and crossbeam screws 2132 for fixing. The outer surface of the "L" shape serves as the first limiting surface 2221 of the first limiter 222. The shape and position of the first limiting surface 2221 of the first limiter 222 are selected according to the outer surface of the stringer positioning mold 223. The bottom of the first limiter 222 is 20mm higher than the upper surface of the lower flange of the stringer precast body A.

[0050] The “J”-shaped stringer is an uncured stringer, and during molding, it includes a stringer positioning mold 223 and a stringer auxiliary mold 225. The first limiting surface 2221 of the first limiter 222 positions the stringer precast body A through the outer surface of the stringer positioning mold 223. The stringer positioning mold 223 and the first limiter 222 are connected and fixed by screws 3. The positional relationship between the “J”-shaped stringer precast body A with the stringer positioning mold 223 and the first limiter 222 is as follows. Figure 3 As shown in (d), no auxiliary material is used between the first limiting surface 2221 of the first limiter 222 and the positioning surface of the stringer positioning mold 223.

[0051] To ensure the positional accuracy of the first limiting surface 2221 of the multiple first limiters 222, during the preparation of the positioning frame 2, 48 "L"-shaped first limiters 222 are combined and fixed with the first longitudinal beam 211, the second longitudinal beam 212, 2 reinforcing beams 214, and 6 cross beams 213, and then the first limiting surface 2221 of the first limiters 222 is processed uniformly.

[0052] The second limiter 224 is positioned opposite to the first limiter 222. The second limiter 224 and the first limiter 222 are connected by screws 3. When the eight "J"-shaped stringers, the stringer positioning mold 223, and the stringer auxiliary mold 225 are assembled with the positioning frame 2, the second limiter 224 provides height-direction limiting and clamping for the position of the stringers.

[0053] The gap between the fourth limiting surface 2242 of the second limiter 224 and the upper surface of the stringer auxiliary mold 225 (i.e., the top surface position of the eight "J"-shaped stringers, their stringer positioning mold 223, and the stringer auxiliary mold 225 assembly) is determined according to the thickness of the auxiliary material used between them, and is 0.2 mm in this embodiment. A 1 mm gap is reserved between the third limiting surface 2241 of the second limiter 224 and the outer surface of the stringer auxiliary mold 225. The cross-sectional shape and dimensions of the second limiter 224 vary according to the external cross-section of the "J"-shaped stringer auxiliary mold, and the cross-sectional shape of the second limiter 224 and its positional relationship with the first limiter 222 are as follows. Figure 5 As shown in (i).

[0054] The eight "J"-shaped stringers are pre-positioned using positioning frame 2 to ensure their positional relationship. Then, positioning frame 2 is flipped over so that reinforcing beam 214, crossbeam 213, first longitudinal beam 211, and second longitudinal beam 212 are at the bottom, and first limiter 222 and second limiter 224 are at the top. The eight "J"-shaped stringers, stringer positioning mold 223, and stringer auxiliary mold 225 are then assembled and clamped one by one at the corresponding positions on positioning frame 2.

[0055] The specific assembly process is as follows: First, loosen the screws 3 between the first limiter 222 and the second limiter 224. Place the assembly of 8 "J"-shaped stringers, stringer positioning mold 223, and stringer auxiliary mold 225 on the fourth limiting surface 2242 of the second limiter 224 corresponding to the positioning frame 2 to limit the height of the "J"-shaped stringers. Initially position the stringers in the length direction according to the position of the first limiter 222 at the end of the corresponding "J"-shaped stringer on the positioning frame 2. Connect and fix the first limiter 222 and the stringer positioning mold 223 with screws 3. Place a 1.5mm thick Airpad rubber layer between the stringer auxiliary mold 225 and the third limiting surface 2241 of the second limiter 224. Tighten the screws 3 between the first limiter 222 and the second limiter 224, and use a clamp to clamp the 8 "J" shaped stringers, the stringer auxiliary mold 225 and the stringer positioning mold 223. The clamp is located between the stringer precast body A and the crossbeam 213.

[0056] After the eight "J"-shaped long trusses, the long truss positioning mold 223, the long truss auxiliary mold 225, etc. are assembled, positioned, and clamped with the positioning frame 2, the assembled eight "J"-shaped long trusses, the long truss positioning mold 223, the long truss auxiliary mold 225, etc. are flipped together with the positioning frame 2 and transferred to the outer mold 1 on which the skin precast body B has been positioned and installed. The first longitudinal beam 211, the second longitudinal beam 212 and the positioning block 215 on the outer mold 1 are positioned by the positioning pin 216. After the positioning frame 2 and the outer mold 1 are positioned, the eight "J"-shaped long trusses are placed and positioned on the skin precast body B at the same time, ensuring the positional relationship between the eight "J"-shaped long trusses and the skin precast body B on the outer mold 1. Figure 1 The diagram shows the positioning of all eight "J"-shaped stringers, stringer positioning mold 223, stringer auxiliary mold 225, and positioning frame 2 on the skin precast body B.

[0057] Example 2 In this embodiment, the high-density multi-reinforced composite wall panel to be prepared is a curved reinforced wall panel with a length of 15000mm and an unfolded width of 2950mm. It has 20 "T"-shaped stringers (stringer prefabricated bodies A), with a spacing of 140mm between the axes of adjacent stringer prefabricated bodies A. The height of stringer prefabricated body A is 100mm. The "T"-shaped stringers are cured, and the skin prefabricated body B is uncured. All "T"-shaped stringers and skin prefabricated bodies B are co-bonded. This high-density multi-reinforced composite wall panel is large in size, has a large number of stringers, and the 20 stringers have a small spacing and high density. The skin span is also large, making traditional positioning methods unsuitable for positioning this reinforced wall panel structure. The positioning of the stringer prefabricated bodies A and skin prefabricated bodies B adopts the positioning method for high-density multi-reinforced composite wall panel forming provided by this invention. The specific operation method is as follows: The positioning device for forming high-density multi-reinforced composite wall panels provided in this embodiment includes a positioning frame 2 and connecting parts, lifting rings, etc., as well as related outer mold 1, outer mold positioning block 215, pad block 217, etc.

[0058] The overall positioning frame 2 consists of a first longitudinal beam 211, a second longitudinal beam 212, multiple crossbeams 213, a first limiter 222, and a second limiter 224. The width of the positioning frame 2 is equal to the width of the outer mold 1, and the length of the first longitudinal beam 211 and the second longitudinal beam 212 is equal to the length of the precast truss A. The first longitudinal beam 211 and the second longitudinal beam 212 are positioned on the outer mold 1 by positioning blocks 215. The positioning blocks 215 are located at both ends of the first longitudinal beam 211 and the second longitudinal beam 212 and are flush with the ends of the precast truss A, and are fixedly connected to positioning pins 216. Crossbeams 213 are installed and fixed at the ends of the first longitudinal beam 211 and the second longitudinal beam 212. Fourteen crossbeams 213 are distributed in the middle area of ​​the first longitudinal beam 211 and the second longitudinal beam 212, and the ends of the crossbeams 213 are flush with the outer sides of the first longitudinal beam 211 and the second longitudinal beam 212. The two ends of the crossbeam 213 are positioned with the first longitudinal beam 211 and the second longitudinal beam 212 by pins and fixed above the first longitudinal beam 211 and the second longitudinal beam 212 by screws. In addition, two pads 217 fixed to the outer mold 1 are provided between the lower surface of the middle area of ​​the first longitudinal beam 211 / second longitudinal beam 212 and the outer mold 1.

[0059] The first limiter 222 is located between the stringer positioning mold 223 and the crossbeam 213, and is used to position the stringer precast body A. A total of 320 first limiters 222 are installed between the 16 crossbeams and the 20 "T"-shaped stringers. The cross-section of the first limiter 222 is designed as an approximately "L"-shaped structure. The upper edge of the "L"-shaped structure mates with the crossbeam 213, and the connection method is designed to be detachable, using crossbeam pins 2131 for positioning and crossbeam screws 2132 for fixing. The outer surface of the "L"-shaped structure serves as the first limiting surface 2221 of the first limiter 222. The "T"-shaped stringers are already cured stringers; when they are bonded and cured with the skin precast body B, the stringer positioning mold 223 is not used. The first limiting surface 2221 of the first limiter 222 directly positions one side of the web of the "T"-shaped stringer. The positional relationship between the "T"-shaped stringer precast body A without the stringer positioning mold and the first limiter 222 is as follows: Figure 2 As shown in (b), the first limiting surface 2221 of the first limiter 222 is selected according to the preset positioning surface A1. The bottom position of the first limiter 222 is 10mm higher than the upper surface of the lower flange of the precast stringer A. The gap between the first limiting surface 2221 of the first limiter 222 and the preset positioning surface A1 is determined according to the thickness of the auxiliary material used between the two during molding. In this embodiment, it is preferably 0.2mm.

[0060] To ensure the positional accuracy of the first limiting surface 2221 of the multiple first limiting devices 222, during the preparation of the positioning frame 2, 320 "L"-shaped first limiting devices 222 are combined and fixed with the first longitudinal beam 211, the second longitudinal beam 212, and 17 cross beams 213, and then the first limiting surface 2221 of the first limiting devices 222 is processed uniformly.

[0061] The second limiter 224 is arranged opposite to the first limiter 222, and there are 320 of them. The second limiter 224 and the first limiter 222 are connected by screws 3, which are used to provide height direction limit and clamping function for the position of the 20 "T" shaped long stringers when they are assembled with the positioning frame 2.

[0062] The reserved gap between the fourth limiting surface 2242 of each second limiter 224 and the top surface of the "T"-shaped stringer is determined according to the thickness of the auxiliary material used between them, which is 0.2 mm in this embodiment. A 0.5 mm gap is reserved between the third limiting surface 2241 of the second limiter 224 and the web surface on the same side of the "T"-shaped stringer. The cross-sectional shape and dimensions of the second limiter 224 are determined based on the cross-section of the "T"-shaped stringer. The cross-sectional shape of the second limiter 224 and its positional relationship with the first limiter 222 are as follows: Figure 4 As shown in (b).

[0063] Twenty T-shaped stringers are pre-positioned using positioning frame 2 to ensure their positional relationship. Then, positioning frame 2 is flipped over so that the crossbeam 213, the first longitudinal beam 211, and the second longitudinal beam 212 are at the bottom, and the first limiter 222 and the second limiter 224 are at the top. The 20 T-shaped stringers are then assembled and clamped one by one at their corresponding positions on positioning frame 2.

[0064] When assembling each "T"-shaped stringer, first loosen the screws 3 between the corresponding first limiter 222 and second limiter 224. Place each of the 20 "T"-shaped stringers one by one into the corresponding position on the positioning frame 2, ensuring that the preset positioning surface A1 aligns with the first limiting surface 2221 of the first limiter 222. Based on the pre-reserved gap between the first limiting surface 2221 of the first limiter 222 and the preset positioning surface A1 of the stringer prefabricated body A, place auxiliary material of equal thickness between the preset positioning surface A1 of the stringer prefabricated body A and the first limiting surface 2221 of the first limiter 222. Position the stringers along their length according to the position of the corresponding first limiter 222 on the positioning frame 2. The "T"-shaped stringer is height-limited by the fourth limiting surface 2242 of the second limiter 224. Based on the pre-reserved gap between the fourth limiting surface 2242 of the second limiter 224 and the top surface of the stringer precast body A, an auxiliary material of equal thickness is placed between the top surface of the stringer precast body A and the fourth limiting surface 2242 of the second limiter 224. A 1mm thick rubber-like material is placed between the stringer precast body A and the third limiting surface 2241 of the second limiter 224. The screws 3 between the first limiter 222 and the second limiter 224 are tightened.

[0065] After the 20 "T"-shaped trusses are assembled, positioned, and clamped with the positioning frame 2, the assembled 20 "T"-shaped trusses and the positioning frame 2 are flipped over and transferred to the outer mold 1 on which the skin precast body B has been positioned and installed. The first longitudinal beam 211, the second longitudinal beam 212, and the positioning block 215 on the outer mold 1 are positioned by the positioning pin 216. After the positioning frame 2 and the outer mold 1 are positioned, the positioning and installation of all the truss precast bodies A on the skin precast body B is realized, ensuring the positional relationship between all the truss precast bodies A and the skin precast body B on the outer mold 1.
