Description

Technical Field

[0001] This utility model belongs to the field of thermal insulation material technology, and relates to a novel assembly structure for insulating thermal insulation boards. Background Technology

[0002] In scenarios requiring thermal insulation for liquefied gas cryogenic storage tanks or liquefied gas transport ships, the surface of the metal hull is typically covered with insulation panels to provide cold insulation performance. Existing insulation panels mostly use foamed materials combined with panels to form a multi-layer cold insulation structure, similar to the structures disclosed in Chinese patents CN211662770U and CN117071763B. These insulation panels all have corresponding specifications in size. Existing insulation panels are mostly installed using an embedded installation mode, where multiple insulation panels need to be installed in a set direction and sequence, and each insulation panel needs to be aligned with the adjacent insulation panel to ensure the neatness of the overall installation. Since insulation panels will undergo thermal expansion and contraction during use, the existing embedded installation mode has excessively high requirements for the alignment of adjacent insulation panels and the allowance for joints. If these requirements are not met, it will lead to compression deformation between insulation panels or excessive joint leakage, affecting the overall cold insulation effect. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a novel assembly structure for insulating and heat-preserving boards.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel insulation board assembly structure includes multiple insulation boards disposed on an installation surface. The insulation boards are fixedly connected to the installation surface. A first joint and a second joint are formed between adjacent insulation boards from the inside out. A first flexible member is disposed in the first joint, and a prefabricated member is disposed in the second joint. The prefabricated member includes an intermediate member and a second flexible member disposed on the outer periphery of the intermediate member.

[0006] Furthermore, the insulation board includes an inner layer, an outer layer, and an outer protective layer. The inner layer and the outer layer are both foamed boards, the outer protective layer is a TPO waterproof membrane, and a reinforcing layer is provided between the inner layer and the outer layer. The reinforcing layer is a stainless steel wire mesh or an aluminum foil mesh. The inner layer, the reinforcing layer, the outer layer, and the outer protective layer are bonded together in sequence.

[0007] Furthermore, a first seam is formed between adjacent inner layers, and a second seam is formed between adjacent outer layers, wherein the width of the second seam is greater than the width of the first seam.

[0008] Furthermore, one or more bolts are provided in the first joint, and a U-shaped piece and a nut are sequentially threaded through the bolts. The U-shaped piece has wing plates on both sides for abutting against the two adjacent inner layers.

[0009] Furthermore, it also includes a reinforcing member, which is bonded to the bottom of the second joint, and the reinforcing member comprises layers of stainless steel wire mesh and aluminum foil mesh.

[0010] Furthermore, it also includes a closure that closes the top opening of the second seam, and the two sides of the closure are respectively connected to the two adjacent outer protective layers.

[0011] Furthermore, a step is provided on the top outer periphery of the outer layer, and the steps of two adjacent outer layers are combined to form a staggered groove with a width greater than that of the second joint, and the sealing member closes the staggered groove.

[0012] Furthermore, the sealing element is a TPO waterproof membrane, and the sealing element and the outer protective layer are fused together using a hot air welding process.

[0013] Furthermore, the inner layer, the outer layer, and the intermediate component are made of polyurethane foam or expandable polystyrene.

[0014] Furthermore, multiple insulating and heat-preserving boards are arranged in an array on the mounting surface.

[0015] In summary, the advantages of this utility model are as follows:

[0016] The insulation board assembly structure of this utility model improves cold insulation performance by filling the joints between adjacent insulation boards to avoid exposed joints. The double-joint design, consisting of a first joint and a second joint, combined with the width difference between the two joints, effectively reduces or prevents board compression or exposed joints when the insulation board expands and contracts due to temperature changes, thus improving durability and cold insulation performance. The double joints are respectively filled with a first flexible component and a prefabricated component, causing the first and second flexible components to be staggered, increasing the cold air leakage path and further enhancing cold insulation performance.

[0022] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0024] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0025] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of this utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0026] This utility model provides a novel insulating insulation board suitable for the insulating enclosure system of liquefied gas ship cargo tanks. It is generally installed on the surface of the metal tank. Under normal operating conditions, the insulating insulation board will be used for a long time in a low-temperature environment and withstand the temperature transferred from the low-temperature liquefied gas. The insulating insulation board has a multi-layer structure and has excellent cold insulation performance, stability and service life.

[0027] Specifically, refer to Figure 1 The insulation board consists of an inner layer 1, an outer layer 2, and an outer protective layer 4 from the inside out. The inner layer 1 is the inner side of the insulation board, which is installed in contact with the surface of the metal cabin. The outer protective layer 4 is the outer side of the insulation board, which serves as external protection.

[0028] Preferably, the inner layer 1 and the outer layer 2 are made of the same material, both being PUF (polyurethane foam) or EPS (expandable polystyrene). They are in the form of foam blocks or foam boards of a set thickness, and have excellent thermal insulation and heat insulation properties. They can be produced by online mixing and continuous foaming of multi-component raw materials. They are suitable for thermal insulation in industrial fields such as construction, transportation, petroleum, chemical, power, and refrigeration, especially in the thermal insulation needs of liquefied gas cryogenic storage tanks or liquefied gas transport ships.

[0029] As a preferred option, the outer protective layer 4 is made of TPO waterproof membrane, namely thermoplastic polyolefin waterproof membrane. It is a new type of waterproof membrane made of resin and ethylene, acetic acid and ethylene resin as base materials, with added antioxidants, anti-aging agents and softeners, and the surface is covered with fabric fibers and aluminum film. Its material physical properties meet the requirements of "Polymer Waterproof Materials" (GB18173-2000). It combines the properties of EPDM and PVC, and has the advantages of excellent aging resistance, can be exposed to sunlight for a long time, long service life, strong puncture resistance, good low temperature flexibility, strong adaptability to environmental temperature changes, wide range of applications and excellent environmental performance. Therefore, using it as the outer surface of the insulation board ensures the strength and protection capabilities, and also prevents the outer protective layer 4 from being damaged by thermal expansion and contraction caused by extreme environmental temperature changes.

[0030] Furthermore, a reinforcing layer 3 is provided between the inner layer 1 and the outer layer 2. The reinforcing layer 3 is made of stainless steel wire mesh or aluminum foil mesh. The reinforcing layer 3 increases the connection strength between the inner layer 1 and the outer layer 2, as well as the overall bending, compressive and tensile strength of the inner layer 1 and the outer layer 2.

[0031] In some preferred embodiments, when multiple insulating insulation boards are regularly installed onto the surface of the metal cabin, a joint filling structure is provided to reduce the impact of the joints between adjacent insulating insulation boards. The joint filling structure includes a first flexible member 12, a second flexible member, an intermediate member, and a reinforcing member 23, as shown in the reference. Figure 2 The intermediate component has a set thickness (height) and width. The second flexible component is wrapped around the outer periphery of the intermediate component to form a preform 22. A second seam 21 is formed between two adjacent outer layers 2. The preform 22 is placed in the second seam 21 and is bonded and fixed to the outer layers 2 on both sides by adhesive. The outer sides of the second flexible component on the preform 22 abut against the outer layers 2 on the left and right sides respectively. A second seam 21 is formed between two adjacent inner layers 1. The first flexible component 12 is filled in the second seam 21. Specifically, the first flexible component 12 is a square frame structure and is attached to the outer periphery of the inner layer 1. When two adjacent inner layers 1 are spliced, the first flexible components 12 on the two inner layers 1 are squeezed and abut against each other.

[0032] The width of the second joint 21 is greater than the width of the first joint 11, so that in a single insulating board, the area of ​​the outer layer 2 is smaller than that of the inner layer 1, and the entire periphery of the outer layer 2 falls within the area of ​​the inner layer 1.

[0033] By setting the width of the second joint 21 to be greater than that of the first joint 11, multiple insulating panels can be better installed on the non-planar surface of the metal cabin. The inner layers 1 of adjacent insulating panels are filled with the first flexible member 12 to provide buffer. A larger joint is set between the outer layers 2 of adjacent insulating panels. On uneven surfaces, this can effectively prevent adjacent insulating panels from colliding and squeezing. At the same time, it also reserves more space to accommodate the thermal expansion and contraction deformation of the insulating panels under working conditions. Furthermore, the combination of the intermediate member and the second flexible member set in the joint of the outer layer 2 results in the first flexible member 12 and the second flexible member having a bent and staggered path after connection in the direction from the inside to the outside of the insulating panel, rather than being a straight line. This effectively increases the leakage length at the joint, reduces the cold leakage rate, and makes the cold insulation performance between adjacent insulating panels better.

[0034] Preferably, the intermediate component is made of PUF or EPS, and both the first flexible component 12 and the second flexible component are made of materials that are resistant to low temperatures and have low thermal conductivity, such as glass wool.

[0035] Furthermore, the reinforcing member 23 is disposed within the second joint 21 and located between the second flexible member and the first flexible member 12. The reinforcing member 23 includes a layered structure of stainless steel wire mesh and aluminum foil mesh. The stainless steel wire mesh is disposed at the bottom of the second joint 21 and is in direct contact with the surfaces of the two inner layers 1. The stainless steel wire mesh is fixed to the two inner layers 1 by glue or pins. The aluminum foil mesh is layered and covers the stainless steel wire mesh and is fixed by glue, thereby sealing the top of the first joint 11 and enhancing the sealing and cold insulation performance of the joint while providing structural reinforcement.

[0036] The top of the second joint 21 is also provided with a sealing element 41. The sealing element 41 is made of the same TPO waterproof membrane as the outer protective layer 4. The width of the sealing element 41 is greater than the width of the second joint 21. The two ends of the sealing element 41 are fused with the outer protective layer 4 on the two adjacent insulating parts by hot air welding process, thereby sealing the first joint 11.

[0037] Furthermore, a step 24 is provided on the top outer periphery of the outer layer 2, and a staggered groove 25 with a width greater than the second joint 21 is formed between two adjacent outer layers 2 through the step 24, forming a staggered joint effect, changing the through joint into an angle. The staggered groove 25 is filled with a second flexible component with a matching width and thickness, and with the setting of the sealing component 41, the top of the second joint 21 is more fully sealed, enhancing the cold insulation effect.

[0038] Furthermore, the preparation of single-insulation insulation boards includes:

[0039] Prepare the sheet material by using a wire cutting machine to cut out the outer layer 2, inner layer 1, outer protective layer 4, and reinforcing layer 3 according to the set size requirements, and mark them respectively.

[0040] Apply adhesive evenly to the inner layer 1 and its surrounding end faces according to the size and process settings. Apply adhesive evenly to the two sides of the outer layer 2 according to the size and process settings. Perform surface treatment on the adhesive surface of the outer protective layer 4.

[0041] Lay the inner layer 1 flat with the adhesive side facing up, lay the reinforcing layer 3 flat on the adhesive side of the inner layer 1, lay the outer layer 2 flat on the reinforcing layer 3, and lay the outer protective layer 4 flat on the outer layer 2.

[0042] The assembled insulation boards are placed in a press and pressed together. Pads are placed according to the set process requirements to maintain pressure and time.

[0043] After the insulation board is pressed, the excess material of the outer protective layer 4 around the outer layer 2 is trimmed by CNC equipment according to the process requirements, and steps 24 are opened around the outer layer 2.

[0044] Product labels and protective films are affixed to the outer protective layer 4 of the insulation board, and the first flexible component 12 is affixed to the four sides of the inner layer 1.

[0045] The assembled insulation boards are stacked on a special tray according to the packaging specifications, protected with paper corner protectors, and then wrapped with black vinyl film. Each tray of products is covered with a transparent plastic bag on top and then wrapped with black vinyl film.

[0046] The assembly of multiple insulating panels includes:

[0047] Based on the dimensions of the mounting surface, calculate the number and arrangement of the insulation boards to be installed. Draw lines on the mounting surface according to the arrangement, marking the edge lines of the installation positions of all the insulation boards to be installed, and set several bolts 13 along the marked lines.

[0048] The insulation boards are preferably arranged in a rectangular array on the mounting surface, forming multiple rectangular frames in the form of an installation area. Marking lines are set on the outer perimeter of the installation area, and multiple bolts 13 are set on any side line of any rectangular frame within the marking lines. Preferably, two bolts 13 with a predetermined spacing are set. Figure 3 As shown, when any insulating insulation board is installed in any installation area on the mounting surface, the insulation board is limited by eight bolts 13 around its perimeter.

[0049] Bolt 13 is preferably fixed to the mounting surface by welding, and bolt 13 is perpendicular to the mounting surface.

[0050] Multiple insulating boards are respectively placed in multiple installation areas, with a first joint 11 and a second joint 21 pre-set between adjacent insulating boards, so that the first flexible member 12 is compressed.

[0051] A U-shaped component is installed on the bolt 13. The end of the bolt 13 passes through the middle of the U-shaped component and is threaded with a nut. The nut abuts against the U-shaped component. By tightening the nut, the height position of the U-shaped component relative to the bolt 13 can be adjusted so that the two ends of the U-shaped component are pressed against the inner layer 1 surface of the second joint 21 on the two adjacent insulation boards. The insulation board is fixed to the mounting surface by multiple U-shaped components around its perimeter.

[0052] Reference Figure 4 As shown, the U-shaped part has a U-shaped recess in the middle, and a through hole for the bolt 13 to pass through is provided at the bottom of the recess. The nut is threaded onto the bolt 13 and abuts against the surface of the U-shaped part. Wings are provided on opposite sides of the U-shaped part extending laterally. The recessed part of the U-shaped part can enter the first joint 11, and the wings on both sides abut against the inner layer 1 surface of the adjacent insulation board.

[0053] A reinforcing member 23 is provided on the bottom surface of the second joint 21 to seal the top of the first joint 11.

[0054] A prefabricated component 22 is placed inside the second joint 21, and the two sides of the second flexible component of the prefabricated component 22 are bonded to the two outer layers 2 by adhesive.

[0055] A sealing element 41 is provided at the top of the second joint 21, and the sealing element 41 is fused with the outer protective layer 4 of the adjacent two-sided insulation board by hot air welding.
