[0037] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0038] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0039] Figure 1 is a schematic diagram of an enclosure structure provided according to an embodiment of the utility model, Figure 2 Schematic diagram of a frame structure provided according to an embodiment of the utility model. This embodiment can be applied to clean rooms, such as Figure 1 As shown, the enclosure structure includes: at least two sections of enclosure walls 1, a welding structure (not shown in the figure) and a connecting structure 2; the enclosure wall 1 includes a frame structure 3 arranged at the end of the enclosure wall and a plate structure 4 arranged on at least one side surface of the enclosure wall 1; Figure 2As shown, the frame structure includes a groove 31; the welding structure is arranged between two adjacent sections of the enclosing wall 1 and is respectively connected to two adjacent sections of the plate structure 4; the welding structure is made of the same material as the plate structure 4; the connecting structure 2 is arranged between two adjacent frame structures 3; the connecting structure 2 includes a protrusion 21; the protrusion 21 is clamped with the groove 31 to connect the two adjacent sections of the enclosing wall 1.

[0040] Specifically, the joints between two adjacent sections of the enclosure wall 1 can be processed by hot melt welding, and this joint method requires the use of matching welding wires for welding. The welding structure 1 can be a welding wire, and the plate structure 4 on the surface of the enclosure wall 1 can be made of Armstrong solid wall dragon series PVC board. The material of the welding structure 1 and the plate structure 4 use the same material to achieve homogeneous welding, so that the enclosure wall 1 can play a truly seamless seal and greatly reduce the leakage rate.

[0041] Among them, Armstrong Guqianglong series PVC board has anti-collision, impact resistance, scratch resistance and antibacterial functions; high chemical resistance, can withstand corrosion from reagents such as hydrogen peroxide, strong acids and alkalis; light weight, the finished product unit weight is 8.8kg / ㎡; therefore, using Armstrong Guqianglong series PVC board as the board structure 4 can make the surface of the enclosure wall 1 more resistant to various acid and alkali corrosion, and more perfect excellent performance such as scratch resistance. In addition, the Guqianglong series PVC board has rich colors, rich colors are good medicine for the spirit, and reasonable color matching can free people from the depressed environment and tired feeling.

[0042] It should be noted that the production of PVC boards requires strict control of the quality of raw materials, including thickness, flatness, and color. Generally, the PVC board made into a 50mm thick finished product is 1mm thick. After checking the color, surface treatment (rough or smooth) and other parameters, the materials are picked up and sent to the processing area; the amount of standard boards is calculated according to the material list and the combination of large and small materials is considered; sliding table saws or digital engraving machines can be used for processing; the length, width and diagonal dimensions of the cut PVC boards need to be sampled and checked to ensure that the size of each piece meets the requirements.

[0043] The frame structure 3 is a specially designed keel frame. The keel frame can be divided into steel keels and aluminum keels according to the occasion of use. The steel keel is suitable for occasions with high fire protection requirements, and the aluminum keel is suitable for more delicate occasions. Among them, the processing of steel keels is relatively simple. Generally, there is a special keel machine, which can directly cut according to the cutting size, which is relatively fast and convenient; aluminum keels are relatively complicated, generally including cutting, splicing, welding and other processes. No matter which form of keel is used, the size of the spliced ​​keel must be consistent, such as length, width, diagonal, etc.

[0044] The connecting structure 2 is made of aluminum, wherein the frame structure 3 is provided with a groove 31, and a protrusion 21 corresponding to the groove structure 31 is provided on the connecting structure 2 so as to be mutually engaged with the groove 31. The frame structure 31 is arranged at the end of the enclosing wall 1. Through the engagement of the groove 31 and the protrusion 21, on the one hand, the two adjacent enclosing walls 1 can be firmly connected, and on the other hand, the plate structure 4 can be prevented from being misaligned.

[0045] After the embodiment of the utility model connects two adjacent frame structures through the connecting structure, it fixes the two adjacent sections of the enclosing wall and reduces the gap between the two adjacent sections of the enclosing wall, which is convenient for welding the welding structure and the plate structure on the surface of the two adjacent sections of the enclosing wall, and improves the welding stability. At the same time, the plate structure welded together is conducive to maintaining the connection stability between the connecting structure and the frame structure. The two complement each other, so that the enclosing wall can achieve a truly seamless seal, with a smooth appearance without dead angles, safe and stable sealing, simple structure, resistance to various acid and alkali corrosion, reduced leakage rate, and novel and beautiful style.

[0046] Optionally, Figure 3 is a schematic diagram of a protective wall provided according to an embodiment of the utility model, Figure 4 is a schematic diagram of another enclosure structure provided according to an embodiment of the utility model, Figure 5 This is another schematic diagram of a protective structure provided by the embodiment of the utility model. Figure 3 , Figure 4 and Figure 5 As shown, the enclosure wall 1 includes a first enclosure wall 11, and the first enclosure wall 11 is used to form the side surface and / or the top surface of the enclosure structure;

[0047] The first enclosure wall 11 includes a first plate structure 111 and a second plate structure 112 . The first plate structure 111 and the second plate structure 112 are arranged on two opposite side surfaces of the first enclosure wall 11 .

[0048] Specifically, refer to Figure 3 , Figure 4 as well as Figure 5 The sides of the enclosure structure are walls, and the top surface of the enclosure structure is the ceiling. Usually, the first enclosure wall 11 constituting the wall and the ceiling is provided with the same plate structure 4 on both sides of the oppositely arranged surfaces. Multiple rooms can be formed by the enclosure wall 1, and there will be mutual leakage between two adjacent rooms. This requires that the material of the surface of the enclosure structure needs to have safe and stable airtightness. The first plate structure 111 and the second plate structure 112 are provided on both sides of the first enclosure wall 11. The advantage of such a setting is that two adjacent rooms can share a section of the first enclosure wall 11, and there is no need to set multiple first enclosure walls 11 between two adjacent rooms. While meeting the safe and stable airtightness requirements of the enclosure wall, it can also save material costs.

[0049] Optionally, the enclosure wall 1 further includes a bearing layer; the bearing layer is arranged in close contact with the plate structure 4 to bear the plate structure 4.

[0050] Specifically, the bearing layer can be a gypsum board, which is usually used for interior walls. Its main function is to provide a flat surface and a certain sound insulation effect. Therefore, the bearing layer fits the plate structure 4, which can bear the plate structure 4 on the one hand and ensure the flatness of the enclosure structure on the other hand.

[0051] It should be noted that the production of gypsum board requires strict control of the quality of raw materials, including thickness, flatness, and confirmation of the performance of the gypsum board (fireproof, water-resistant, etc.). The thickness of the gypsum board is determined according to the usage scenario, generally 9.5mm or 12mm paper-faced gypsum board.

[0052] Alternatively, if Figure 3 As shown, the enclosure wall 1 also includes a reinforcement layer 5;

[0053] The reinforcement layer 5 is arranged on a side of the bearing layer away from the plate structure 4 , and the rigidity of the reinforcement layer 5 is greater than the rigidity of the bearing layer.

[0054] Specifically, the reinforcing layer 5 can be a paper honeycomb, which has a greater rigidity. Due to its unique structural design, the paper honeycomb material provides high rigidity while being lightweight. The honeycomb structure can effectively disperse stress when subjected to external force through its hexagonal or other polygonal geometric shape, thereby improving the overall rigidity and bearing capacity of the material. Therefore, the reinforcing layer 5 is arranged on the side of the bearing layer away from the plate structure 4. Due to its excellent rigidity, it can bear the enclosing wall 1 to ensure the stability of the enclosing structure. In addition, the reinforcing layer 5 can increase the hardness of the enclosing wall 1. Walls with higher hardness usually have better anti-pollution properties, are not easy to absorb dust and dirt, and are more convenient to clean.

[0055] It should be noted that the plate structure 4, the bearing layer and the reinforcing layer 5 are pressed together to form the enclosure wall 1, and a two-component adhesive is required to be used to strengthen the plate structure 4, the bearing layer and the reinforcing layer 5. Generally, this type of adhesive begins to set in 30 minutes and reaches maximum strength in 4-8 hours. In order to make the glue blend more evenly and the strength more reliable, a steel press is used for gravity pressing. The enclosure wall 1 produced by pressing the above-mentioned several types of plate layers can not only ensure the integrity and strength of the enclosure structure, but also make the surface of the enclosure structure smooth and seamless, which is easy to clean.

[0056] Optionally, the enclosure wall 1 further includes a filling structure; the filling structure is filled in the frame structure.

[0057] Specifically, the filling structure can be rock wool strips, which are a thermal insulation material made of natural basalt as the main raw material, and have excellent heat insulation, fire resistance and sound absorption performance. The rock wool strips need to be staggered and tightly arranged in the keel frame, which can increase the sound insulation and fire resistance of the enclosure wall 1.

[0058] Alternatively, if Figure 4 and Figure 5 As shown, the enclosure wall 1 includes a second enclosure wall 12, and the second enclosure wall 12 is used to form the bottom surface of the enclosure structure;

[0059] The second enclosure wall 12 includes a third plate structure 121 , and the third plate structure 121 is disposed on a side surface of the second enclosure wall 12 .

[0060] Specifically, refer to Figure 4 and Figure 5 The second enclosing wall 12 is used as the bottom surface of the enclosing structure, that is, the ground. Since the second enclosing wall 12 is made based on the floor, the second enclosing wall 12 only needs to be provided with the third plate structure 121 on one side, wherein the third plate structure 121 can be Armstrong enhanced health dragon series PVC floor or Armstrong solid wall dragon series PVC board. Usually, the third plate structure 121 uses the same Armstrong solid wall dragon series PVC board as the first plate structure 111 and the second plate structure 112. The advantage of this is that the third plate structure 121 can be welded homogeneously with the first plate structure 111 and the second plate structure 112, so that the enclosing structure can be truly integrated and seamlessly sealed.

[0061] Optionally, refer to Figure 4 and Figure 5 , the second enclosure wall 12 also includes a self-leveling layer (not shown in the figure) and a waterproof layer (not shown in the figure);

[0062] The self-leveling layer is disposed in close contact with the third plate structure 121 , and the waterproof layer is located on a side of the self-leveling layer away from the third plate structure 121 .

[0063] Specifically, the self-leveling layer is a modern ground treatment process, which uses specially formulated cement or other materials, adds water and mixes to form a liquid substance with a certain fluidity, which flows freely on the ground to fill the unevenness of the ground, and finally forms a smooth, flat hard surface. The self-leveling layer is arranged in affixed manner with the third plate structure to ensure the flatness of the second enclosure wall 12. In addition, a waterproof layer is arranged on the side of the self-leveling layer away from the third plate structure 121, which can further ensure the waterproofness of the enclosure structure.

[0064] Alternatively, if Figure 4 and Figure 5As shown, the first enclosing wall 11 also includes a window 113 and a frame door 114; the window 113 includes: a first light-transmitting layer, a second light-transmitting layer and a vacuum frame, and the vacuum frame is located between the first light-transmitting layer and the second light-transmitting layer; the window 113 is embedded in the first enclosing wall 11 to form an integrated structure with the first enclosing wall; the frame door 114 includes: a panel door leaf and a frame door body; the panel door leaf includes a first section connected to the first enclosing wall and a second section connected to the frame door body; the first section is made of the same material as the panel structure 4.

[0065] Specifically, the first light-transmitting layer and the second light-transmitting layer are 5 mm tempered glass, and the vacuum frame is an aluminum frame. The vacuum frame is set on the first light-transmitting layer and the second light-transmitting layer to form a vacuum window, and the vacuum window is embedded in the first enclosing wall 11. On the one hand, it can form an integrated structure with the first enclosing wall 11, and on the other hand, it can enhance the sound insulation and heat insulation performance of the first enclosing wall 11.

[0066] The panel door leaf is used to connect the first enclosure wall 11 and the frame door body so as to control the opening and closing of the frame door 114. The material of the first section of the panel door leaf is the same as the panel structure 4 to achieve homogeneous welding of the panel door leaf and the first maintenance wall 11, so that the enclosure wall 1 can play a truly seamless seal and further reduce the leakage rate.

[0067] Optionally, the enclosing wall 1 includes a first enclosing wall 11, which is used to form the side surface and / or the top surface of the enclosing structure. The first enclosing wall 11 includes a first plate structure 111 and a second plate structure 112. The thickness of the first plate structure 111 and the second plate structure 112 is L1, 0.8mm≤L1≤1.2mm; the enclosing wall 1 includes a second enclosing wall 12, which is used to form the bottom surface of the enclosing structure. The second enclosing wall 12 includes a third plate structure 121, and the thickness of the third plate structure 121 is L2, 1.8mm≤L2≤2.2mm.

[0068] Specifically, when making the plate structure 4, the thickness can be selected according to the different locations of use. The materials for the walls and ceilings need to be light, and the thickness of the first plate structure 111 and the second plate structure 112 on the first enclosing wall 11 used as walls and ceilings is set to L1, 0.8mm≤L1≤1.2mm, to ensure the lightness of the first enclosing wall 11; the materials for the floor need to be wear-resistant, and the thickness of the third plate structure 121 of the second enclosing wall 12 used as the floor is set to L2, 1.8mm≤L2≤2.2mm, to ensure the long-term durability of the floor.
