Description

Technical Field

[0001] This invention relates to the field of shipbuilding and marine engineering technology, and in particular to a corrugated wedge block and installation method for a membrane tank enclosure system. Background Technology

[0002] The membrane enclosure system is a core component of high-end cryogenic storage and transportation equipment such as LNG carriers and cryogenic storage tanks. It is a key structure for ensuring the safe storage and transportation of cryogenic media, and mainly consists of a main wall membrane, a secondary wall membrane, and a main plywood sandwiched between them. To accommodate the flexible corrugated structure of the membrane to adapt to cryogenic deformation, existing technologies have both the main wall membrane and the secondary wall membrane formed with mutually perpendicular first and second corrugated channels. The main plywood is embedded in the space formed by the two sets of corrugated channels. At the same time, to achieve limiting support and structural reinforcement between the membrane and the main plywood, corrugated wedges need to be installed between the corresponding corrugated channels of the main wall membrane and the secondary wall membrane. The corrugated wedges cooperate with the first notch on the outer wall of the main plywood to achieve fixation, and are key connecting components in the assembly process of the enclosure system.

[0003] In the existing technology, the assembly of the membrane cabin enclosure system adopts a fixed process sequence of first installing the secondary screen membrane, then installing the corrugated wedges, and finally installing the main layer plywood. This assembly method has significant installation defects and has become the core problem restricting the assembly efficiency and installation accuracy of the enclosure system. On the one hand, the corrugated wedges are simply placed on the upper surface of the corrugated channel of the secondary screen wall membrane without any effective positioning or limiting structure. During the subsequent installation of the main plywood, construction workers need to repeatedly and manually adjust the spatial position of the corrugated wedges to ensure precise alignment with the first notch on the outer wall of the main plywood. This operation not only significantly increases the difficulty of the assembly process and severely reduces the overall installation efficiency of the enclosure system, but also easily leads to insufficient installation accuracy of the corrugated wedges due to random errors in manual adjustment, thereby affecting the overall structural stability of the enclosure system. On the other hand, the existing first notch of the main plywood and the corrugated wedge support are in a tight fit, without any reserved installation space. If part of the main plywood is installed first, the corrugated wedge support will be difficult to insert smoothly into the first notch of the installed plywood, resulting in extremely poor assembly flexibility and easy installation interference between the corrugated wedges and the main plywood, further restricting the efficiency of the assembly process. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a corrugated wedge block of a membrane cabin enclosure system, which includes corrugated wedge block support portions disposed on both sides of the corrugated wedge block and extending into the first notch;

[0006] The first notch allows the corrugated wedge support portion of the corrugated wedge to be placed into the first space and rotated for placement;

[0016] As a preferred embodiment of the corrugated wedge block of the membrane cabin enclosure system of the present invention, wherein: the outer wall of the corrugated wedge block support portion is recessed inward to form a notch in the corrugated wedge block support portion.

[0017] As a preferred embodiment of the corrugated wedge block of the membrane cabin enclosure system of the present invention, wherein: the outer wall of the corrugated wedge block support portion on both sides of the corrugated wedge block is provided with a first inclined surface; the first inclined surface is inclined to the upper end of the inside of the first notch.

[0018] As a preferred embodiment of the corrugated wedge block of the membrane cabin enclosure system of the present invention, the main plywood has a rectangular structure, and the main plywood has the first notch on each side, and each side has a plurality of the first notches.

[0019] The beneficial effects of this invention are as follows: While retaining the stable support function for the main plywood and the main screen wall membrane, this invention simplifies the installation process through the inclined surface design, making it operable by a single person and more convenient for maintenance and replacement, and also assisting in the positioning of adjacent components; the planar treatment of the inclined surface and the buffer platform effectively increases the internal space, increases the nitrogen storage capacity, and, together with the activity space, solves the problem of slow inflation; the structural reduction achieves lightweighting, the reserved gap can adapt to the deformation requirements of thermal expansion and contraction, and the first arc surface can also provide a fulcrum and positioning point for the main screen wall membrane screw connection, comprehensively improving the assembly efficiency and operational stability of the membrane cabin enclosure system.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1: Refer to Figures 1-7 This is the first embodiment of the present invention, which provides a corrugated wedge for a membrane cabin enclosure system.

[0037] Specifically, such as Figure 3 As shown, the main plywood 11 is disposed between the main screen wall film 12 and the secondary screen wall film 13. In the prior art, both the main screen wall film 12 and the secondary screen wall film 13 are provided with a first corrugated channel 14 and a second corrugated channel 15, and the first corrugated channel 14 and the second corrugated channel 15 are perpendicular to each other. The main plywood 11 is placed in the space enclosed by the first corrugated channel 14 and the second corrugated channel 15 of the main screen wall film 12 and the secondary screen wall film 13. At the same time, corrugated wedges 10 are installed between the corresponding first corrugated channel 14 or second corrugated channel 15 of the main screen wall film 12 and the secondary screen wall film 13. Corrugated wedge support portions 20 are provided on both sides of the wedge 10. The corrugated wedge support portions 20 and the first notch 111 of the main plywood 11 form a first space 101. The corrugated wedge support portions 20 are installed into the first notch 111 of the outer wall of the main plywood 11, and there is still a channel for movement. That is, there is an installation distance between the outer wall of the corrugated wedge support portion 20 and the inner wall of the first notch 111 of the outer wall of the main plywood 11. The advantage of this design is that it ensures that one end of the corrugated wedge 10 can be inserted into the first notch 111 of the main plywood 11 when the main plywood 11 is installed. Figure 3 As shown, the corrugated wedge support 20 at one end of the corrugated wedge 10 can be inserted into the first notch 111 on the outer wall of the main plywood 11. Then, the corrugated wedge 10 is rotated to rest on the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13. Subsequently, the surface of the corrugated wedge 10 will abut against the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13, thus realizing the installation of the corrugated wedge 10. This facilitates the installation of the surrounding main plywood 11 without needing to adjust the position of the corrugated wedge 10. That is, first, a main plywood 11 is installed. After installation, the position of the first notch 111 on the outer wall of this main plywood 11 is fixed. Then, the first main plywood 11 is installed... One end of the corrugated wedge 10 is inserted into the first notch 111 on the outer wall of the first main plywood 11. After installation, the corrugated wedge 10 is placed on the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13. The upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13 limits the contact point of the corrugated wedge 10. This, together with the first notch 111 around the first installed main plywood 11, restricts the corrugated wedge 10, thereby limiting the installation position of the corrugated wedge 10. Then, the first notch 111 on the outer wall of the main plywood 11 around the first main plywood 11 is aligned with the other end of the corrugated wedge 10, thus realizing the installation of the main plywood 11 around the periphery.

[0038] In the original installation process, the secondary screen wall film 13 needs to be installed first, followed by placing the corrugated wedge 10 on the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13. Then, when installing the main plywood 11, the position of the corrugated wedge 10 is continuously adjusted so that the position of the corrugated wedge 10 is aligned with the position of the first notch 111 of the main plywood 11. The advantage of our solution is that by first installing a main plywood 11, the position of the first main plywood 11 is fixed. By fixing the position of the first main plywood 11, the position of the first notch 111 is fixed, and the insertion position of the corrugated wedge support 20 at one end of the corrugated wedge 10 is fixed. With the contact point on the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13, the position of the corrugated wedge 10 is fixed, which facilitates the subsequent installation of the main plywood 11. The position of the corrugated wedge 10 no longer needs to be adjusted, thus optimizing the installation process and improving installation efficiency and accuracy.

[0039] Meanwhile, a first space 101 is formed between the corrugated wedge support 20 and the first notch 111 on the outer wall of the main plywood 11. This design also has the advantage of allowing the corrugated wedge 10 to be installed even when the main plywood 11 is already installed. It also increases the internal space of the membrane chamber enclosure system and the internal nitrogen storage capacity.

[0040] Example 2: Refer to Figures 1-7 This is the second embodiment of the present invention, which provides a corrugated wedge for a membrane cabin enclosure system.

[0041] Preferably, in the prior art, both the main screen wall film 12 and the secondary screen wall film 13 include a first corrugated channel 14 and a second corrugated channel 15; for example Figure 1 As shown, the first corrugated channel 14 and the second corrugated channel 15 are vertically distributed and have an arched structure. Meanwhile, the surface of the corrugated wedge 10 is provided with a first arc surface 102, that is, the first arc surface 102 is formed at the contact point between the arched corrugated wedge 10 structure and the corrugated wedge support 20. When the main screen wall film 12 is installed, the two sides of the bend of the first corrugated channel 14 or the second corrugated channel 15 of the main screen wall film 12 will contact the first arc surface 102, thereby forming a contact point. The advantage of this design is that by limiting the contact position between the main screen wall film 12 and the corrugated wedge 10, it provides an installation support point for the main screen wall film 12. At the same time, it can also be used as a positioning point to facilitate the installation of the main screen wall film 12. That is, when installing the main screen wall film 12, it is only necessary to place the main screen wall film 12 on the surface of the corrugated wedge 10. Furthermore, the main screen wall film 12 is not a single piece, but is composed of multiple main screen wall films 12 welded together. During welding, it can also form a positioning effect between two main screen wall films 12, which facilitates welding.

[0042] Meanwhile, the upper surface of the corrugated wedge support 20 is tangent to the first arc surface 102, and the upper surface of the corrugated wedge support 20 is on the same horizontal plane as the upper surface of the main plywood 11. The significance of this design is that it facilitates the installation of the main screen wall film 12, with the lower surface of the main screen wall film 12 adhering to the upper surface of the main plywood 11. At the same time, the first arc surface 102 is higher than the upper surface of the corrugated wedge support 20, which enables the lower surface of the first corrugated channel 14 or the second corrugated channel 15 of the main screen wall film 12 to abut against the first arc surface 102 on the corrugated wedge 10, thereby achieving a positioning effect between the main screen wall films 12 and facilitating welding.

[0043] Example 3: Reference Figures 1-7 This is the third embodiment of the present invention, which provides a corrugated wedge for a membrane cabin enclosure system.

[0044] The inner side of the corrugated wedge support 20 is provided with a second arc surface 103 that can contact the outer surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13, such as Figure 6 As shown, the second arc surface 103 contacts the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13. During installation, the secondary screen wall film 13 is installed first, followed by a main layer plywood 11, which restricts the position of the first notch 111 on the outer wall of the main layer plywood 11. Then, one end of the corrugated wedge 10 is placed inside the first notch 111 on the outer wall of the first main layer plywood 11. The corrugated wedge 10 is then rotated to place it on the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13. Since the second arc surface 103 will contact the secondary screen wall film 13... The upper surface of the first corrugated channel 14 or the second corrugated channel 15 restricts the position of the corrugated wedge 10. Specifically, the first notch 111 restricts the position of the corrugated wedge 10 along the surface direction of the first corrugated channel 14 or the second corrugated channel 15, and the second arc surface 103 contacts the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13 to restrict the position in the vertical direction. Thus, the position of the corrugated wedge 10 is fixed. When installing the peripheral main layer plywood 11, it is only necessary to align the first notch 111 of the other main layer plywood 11 with the corrugated wedge support 20 at the other end of the corrugated wedge 10.

[0045] Example 4: Reference Figures 1-7 This is the fourth embodiment of the present invention, which provides a corrugated wedge for a membrane cabin enclosure system.

[0046] The corrugated wedge 10 has an arched structure. It rests on the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary shielding membrane 13. A gap exists between the lower surface of the corrugated wedge 10 and the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary shielding membrane 13, forming a filling space 30. When nitrogen is injected, this increases the cross-sectional area through which nitrogen passes, accelerating the nitrogen flow. Similarly, the upper surface of the arched structure of the corrugated wedge 10 forms the same filling space 30 between the lower surface of the first corrugated channel 14 or the second corrugated channel 15 of the primary shielding membrane 12. This increases the internal space of the membrane enclosure system. Simultaneously, the filling space 30 provides accommodation for minor deformations of the primary and secondary shielding membranes 12 and 13 caused by thermal expansion and contraction, preventing deformation of the primary and secondary shielding membranes 12 and 13 that could directly compress and damage the corrugated wedge 10.

[0047] In the membrane enclosure system, nitrogen needs to be filled in. The inertness, dryness, low thermal conductivity and easy pressure control of nitrogen are used to ensure the four core requirements of safety and explosion protection, structural protection, leakage monitoring and auxiliary cold insulation. When filling with nitrogen, the cross-section of nitrogen flow can be increased, thereby increasing the nitrogen filling rate.

[0048] Preferably, the first through hole 104 penetrates the arched structure of the corrugated wedge 10, which can reduce the material weight of the corrugated wedge 10, and at the same time, can further increase the cross-sectional area through which nitrogen passes, and further increase the amount of nitrogen passing through.

[0049] Preferred, such as Figure 4 As shown, the outer wall of the corrugated wedge 10 includes a first straight surface 105. The upper end of the arched corrugated wedge 10 is a straight surface, forming the first straight surface 105. That is, the first straight surface 105 and the lower surface of the first corrugated channel 14 or the second corrugated channel 15 of the main screen wall film 12 form a filling space 30, which further increases the cross-sectional area through which nitrogen passes, further increases the amount of nitrogen passing through, and increases the filling rate.

[0050] Example 5: Refer to Figures 1-7 This is the fifth embodiment of the present invention, which provides a corrugated wedge for a membrane cabin enclosure system.

[0051] The corrugated wedge 10 has an arched structure. It rests on the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13. There is a gap between the lower surface of the corrugated wedge 10 and the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13, forming a filling space 30. When nitrogen is filled, the cross-section of nitrogen can be increased, and the amount of nitrogen passing through can be accelerated. Similarly, the upper surface of the arched structure of the corrugated wedge 10 and the lower surface of the first corrugated channel 14 or the second corrugated channel 15 of the main screen wall film 12 form the same filling space 30.

[0052] In the membrane enclosure system, nitrogen needs to be filled in. The inertness, dryness, low thermal conductivity and easy pressure control of nitrogen are used to ensure the four core requirements of safety and explosion protection, structural protection, leakage monitoring and auxiliary cold insulation. When filling with nitrogen, the cross-section of nitrogen flow can be increased, thereby increasing the nitrogen filling rate.

[0053] Preferably, the upper end of the arched corrugated wedge 10 is recessed downward to form a second through hole 106. The second through hole 106 penetrates the corrugated wedge 10, and the direction of the second through hole 106 is the same as that of the first corrugated channel 14, which has the same effect as the first through hole 104 in embodiment 4. However, the structure is different, which can reduce the weight of the corrugated wedge 10, while increasing the cross-sectional area of ​​nitrogen passage, increasing the amount of nitrogen passage, and improving the nitrogen filling rate.

[0054] Example 6: Refer to Figures 1-7 This is the sixth embodiment of the present invention, which provides a corrugated wedge for a membrane cabin enclosure system.

[0055] Specifically, the first space 101 is formed by the gap between the outer wall of the corrugated wedge support 20 and the inner wall of the first notch 111 of the main plywood 11. That is, there is a first space 101 between the corrugated wedge support 20 and the first notch 111. The first space 101 provides leeway for the installation of the corrugated wedge support 20, ensuring that one end of the corrugated wedge 10 can be directly inserted into the first notch 111 of the main plywood 11 when the main plywood 11 has been installed. At the same time, the first space 101 further increases the internal space of the membrane tank enclosure system and also increases the internal nitrogen storage space. Increasing the nitrogen content space is an "enhancement and upgrade" of the nitrogen protection function of the membrane tank enclosure system. The core value is to maximize the reliability of explosion-proof and structural protection, while optimizing leakage monitoring and slightly increasing cold insulation. It is a further pursuit of high safety standards in high-end membrane tank projects such as LNG ships and cryogenic storage tanks.

[0056] Furthermore, the first space 101 includes an active space 1011 formed between the corrugated wedge 10 and the outer wall of the main plywood 11, and the first space 101 includes a first buffer space 1012 formed by the upper surface of the corrugated wedge support 20 and the upper inner wall of the first notch 111, such as... Figure 3 As shown, an active space 1011 is formed between the outer surface of the corrugated wedge 10 and the outer surface of the main plywood 11. At the same time, the upper surface of the rectangular corrugated wedge support 20 and the upper inner wall of the first notch 111 form a first buffer space 1012. The active space 1011 and the first buffer space 1012 are used to ensure that the corrugated wedge support 20 avoids interference between the corrugated wedge 10 and the main plywood 11 during installation, and ensures that the corrugated wedge support 20 can be smoothly installed into the first notch 111.

[0057] Example 7: Refer to Figures 1-7 This is the seventh embodiment of the present invention, which provides a corrugated wedge for a membrane cabin enclosure system.

[0058] The corrugated wedge support portions 20 on both sides of the corrugated wedge 10 are recessed to form corrugated wedge support portion notches 201, making the corrugated wedge support portion 20 thinner. At the same time, the corrugated wedge support portion notches 201 also serve a avoidance function, allowing the corrugated wedge support portion notches 201 to avoid the first notch 111, facilitating the insertion of the corrugated wedge support portion 20 at one end of the corrugated wedge 10 into the first notch 111. During installation, after a main layer plywood 11 is installed, the corrugated wedge support portion 20 at one end of the corrugated wedge 10 is directly inserted into the first notch 111. This avoids the upper surface of the rectangular corrugated wedge support portion 20 from contacting the outer surface of the main layer plywood 11.

[0059] Example 8: Refer to Figures 1-7 This is the eighth embodiment of the present invention, which provides a corrugated wedge for a membrane cabin enclosure system.

[0060] Based on Embodiment 7, the lower surfaces of the corrugated wedge support portions 20 on both sides of the corrugated wedge 10 are provided with first inclined surfaces 107; the first inclined surfaces 107 are inclined towards the upper end of the first notch 111, that is, the thickness of the corrugated wedge support portion 20 gradually decreases, and at the same time, the direction of the continuous thinning is towards the inside of the first notch 111. The advantage of this design is that when the corrugated wedge support portion 20 is inserted into the first notch 111 of the main plywood 11, the thickness of the corrugated wedge support portion 20 is relatively thin, which facilitates passage through the space between the outer wall of the main plywood 11 and the first corrugated channel 14 or the second corrugated channel 15. That is, the lower surface of the corrugated wedge support portion 20 will not abut against the upper surface of the secondary screen wall film 13. Subsequently, the second arc surface 103 of the corrugated wedge 10 slides along the outer surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13, and the corrugated wedge support portion 20 slides more easily into the first notch 111, which facilitates the installation of the corrugated wedge 10.

[0061] Example 9: Refer to Figures 1-7 This is the ninth embodiment of the present invention, which provides a corrugated wedge block for a membrane cabin enclosure system.

[0062] Preferably, the corrugated wedge 10 has a symmetrical structure. The advantage of the symmetrical structure of the corrugated wedge 10 is that when the corrugated wedge 10 is placed on the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13, the symmetrical structure makes the contact position between the second arc surface 103 of the corrugated wedge 10 and the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13 also symmetrical. During placement, the two second arc surfaces 103 on the inner side of the corrugated wedge 10 slide along the upper surface of the first corrugated channel 14 or the second corrugated channel 15 of the secondary screen wall film 13 and automatically slide down to the contact position, which facilitates the installation of the corrugated wedge 10 and further improves the positional accuracy of the corrugated wedge 10.

[0063] Example 10: Refer to Figures 1-7 This is the tenth embodiment of the present invention, which provides a corrugated wedge block for a membrane cabin enclosure system.

[0064] To enable the installation of a main plywood 11, the corrugated wedge support 20 at one end of the corrugated wedge 10 is inserted into the first notch 111 on the outer wall of the main plywood 11. This is achieved by expanding the first notch 111 to form a curved structure, creating a first surface 1111, a second surface 1112, and a third surface 1113. Preferably, the second surface 1112 is perpendicular to the first surface 1111, and subsequently, the third surface 1113 is perpendicular to the second surface 1112, i.e., the third surface 1113 is parallel to the first surface 1111. Simultaneously, preferably, the third surface 1113 does not adhere to the outer wall of the corrugated wedge support 20; that is, a first space 101 is formed between the second surface 1112, the third surface 1113, and the outer wall of the corrugated wedge support 20. This ensures that even when the corrugated wedge support 20 has a rectangular structure, it can still be installed inside the first notch 111.

[0065] Example 11: Refer to Figures 1-7 This is the eleventh embodiment of the present invention, which provides a corrugated wedge block for a membrane cabin enclosure system.

[0066] Preferably, the notch 201 of the corrugated wedge support portion includes a vertical surface 2011 and a horizontal surface 2012; the vertical surface 2011 of the corrugated wedge support portion 20 and the first surface 1111 of the first notch 111 form an active space 1011.

[0067] like Figure 4 As shown, the corrugated wedge support portion 20 on the outer wall of the corrugated wedge 10 is provided with a corrugated wedge support portion notch 201. At the same time, the corrugated wedge support portion notch 201 includes a vertical surface 2011 and a horizontal surface 2012. The vertical surface 2011 and the first surface 1111 of the first notch 111 form an active space 1011 to prevent the corrugated wedge support portion 20 from contacting the first notch 111 and interfering during installation.

[0068] Furthermore, an active space 1011 is formed between the first surface 1111 of the first notch 111 and the vertical surface 2011 of the notch 201 of the corrugated wedge support portion. A first buffer space 1012 is formed between the second surface 1112 of the first notch 111 and the horizontal surface 2012 of the notch 201 of the corrugated wedge support portion. A second buffer space 1013 is formed between the third surface 1113 of the first notch 111 and the side surface of the corrugated wedge support portion 20. The active space 1011, the first buffer space 1012, and the second buffer space 1013 together constitute the first space 101. That is, there is a gap between the corrugated wedge support portion 20 and the first notch 111, ensuring that the rectangular structure of the corrugated wedge support portion 20 including the notch 201 of the corrugated wedge support portion can smoothly enter the interior of the first notch 111.

[0069] Example 12: Refer to Figures 1-7This is the twelfth embodiment of the present invention, which provides a corrugated wedge for a membrane cabin enclosure system.

[0070] Preferably, the first inclined surface 107 and the third surface 1113 of the first notch 111 form a first space 101.

[0071] The lower surface of the corrugated wedge support 20 is inclined, forming a first inclined surface 107, which continuously reduces the thickness of the corrugated wedge support 20. Furthermore, the sidewall of the corrugated wedge support 20 can contact the third surface 1113, such as... Figure 6 As shown, during installation, because the outer end of the corrugated wedge support 20 is relatively thin when inserted, the bottom of the corrugated wedge support 20 will not contact the surface of the secondary screen membrane 13 during insertion. As the corrugated wedge 10 rotates, the outer end of the corrugated wedge support 20 gradually moves upward without interference. This creates a first space 101 between the third surface 1113 and the first inclined surface 107. The advantage of the first inclined surface 107 design is that it can ensure the installation of the corrugated wedge 10, reduce the weight of the corrugated wedge 10, and at the same time, it can form the first space 101 to provide storage for nitrogen and improve the high safety standard of the membrane enclosure system.

[0072] The horizontal surface 2012 of the notch 201 of the corrugated wedge block support part is in contact with the second surface 1112 of the first notch 111.

[0073] The horizontal surface 2012 of the notch 201 of the corrugated wedge block support is in contact with the second surface 1112 of the first notch 111, which does not affect the installation of the corrugated wedge block 10.

[0074] Example 13: Refer to Figures 1-7 This is the thirteenth embodiment of the present invention, which provides a corrugated wedge for a membrane cabin enclosure system.

[0075] The main plywood 11 has a rectangular structure, and each side of the main plywood 11 is provided with a first notch 111, and each side is provided with multiple first notches 111.

[0076] The main plywood 11 has a rectangular structure. At the same time, two first notches 111 are provided on each of the four sides of the main plywood 11 to ensure the number of corrugated wedges 10 installed and the support strength.

[0077] The main plywood 11 has notches 112 at the four corners of its upper surface.

[0078] The four corners of the upper surface of the main plywood 11 are chamfered to form notches 112, which effectively releases the compressive stress during low-temperature shrinkage and the tensile stress after installation at room temperature, and prevents brittle cracking, warping, delamination and other problems from occurring at the corners of the main plywood 11.

[0079] Example 14: Refer to Figures 1-7 This is the fourteenth embodiment of the present invention, which provides an installation method for a membrane cabin enclosure system.

[0080] The installation of this membrane enclosure system relies entirely on the innovative structure of the corrugated wedges 10 and the main plywood 11, eliminating the tedious process of repeated adjustments and implementing it step by step in a standardized sequence: First, the secondary screen wall membrane 13 is laid, using the vertically distributed arched first corrugated channels 14 and second corrugated channels 15 on the secondary screen wall membrane 13 as the basic support reference for the overall installation; then, the first main plywood 11 is positioned and installed, and it is placed firmly within the space enclosed by the corrugated channels of the main screen wall membrane 12 and the secondary screen wall membrane 13. The first notch 111 on the side of the reference plywood, which has a three-sided turning structure, forms a fixed positioning reference. At the same time, the notches 112 at the four corners of the upper surface of the plywood are used to reserve space for low-temperature stress release to avoid cracking and warping in subsequent use.

[0081] Next, the corrugated wedge 10 is assembled. A symmetrical corrugated wedge 10 is selected, and its corrugated wedge support 20, which has a notch 201 and a first inclined surface 107 on both sides, is inserted into the first notch 111 of the main plywood 11 that has been fixed. Sufficient installation allowance is reserved in the first space 101 formed between the corrugated wedge support 20 and the first notch 111 to avoid assembly interference. Then, the corrugated wedge 10 is rotated so that its inner second arc surface 103 smoothly fits and abuts against the main plywood 11. The secondary screen wall film 13 corresponds to the upper surface of the corrugated channel. The first notch 111 limits the horizontal direction of the corrugated wedge 10, and the second arc surface 103 limits the vertical direction of the corrugated wedge 10, so as to achieve precise positioning and fixation of the corrugated wedge 10 without the need for secondary position adjustment throughout the process. After the corrugated wedge 10 is installed in place, the surrounding main layer plywood 11 is installed in sequence. Simply align the first notch 111 on the side of each plywood with the corrugated wedge support 20 at the other end of the corrugated wedge 10 to complete the rapid splicing.

[0082] The first notch 111, which is arranged on multiple sides of the plywood, ensures the overall support strength. Finally, the main screen wall film 12 is laid and welded. Multiple main screen wall films 12 are laid on top of the corrugated wedge block 10 in sequence, so that the bend of the corrugated channel of the main screen wall film 12 abuts against the first arc surface 102 of the corrugated wedge block 10. The first arc surface 102 is used to achieve support positioning and welding alignment. With the top surface of the corrugated wedge block support part 20, which is flush with the upper surface of the main layer plywood 11, the main screen wall film 12 is flat and attached, and the splicing and welding of multiple films is completed. At the same time, the filling space 30 formed between the arched structure of the corrugated wedge block 10 and the main and secondary screen wall films, together with the first through hole 104, the second through hole 106 and the first straight surface 105 on the wedge block, not only expands the nitrogen flow and storage cross section, but also provides a space to accommodate the slight deformation of the film due to thermal expansion and contraction. The whole installation process is simplified and efficient, and the positioning is accurate, achieving the dual effects of improved installation quality and safety protection at the same time.
