Description

Technical Field

[0001] This utility model relates to the field of assembled wall technology, specifically a flame-retardant and heat-insulating wall that can be installed quickly. Background Technology

[0002] In today's rapidly evolving construction industry, prefabricated wall systems are widely used in various building projects due to their advantages such as short construction cycles and industrialized production capabilities. Traditional prefabricated wall systems are typically constructed from relatively simple panels and frames. Adjacent walls are connected by direct end-to-end butt joints, usually without any special interlocking structure. Therefore, in the event of a fire, the walls deform due to heat, creating an unobstructed, straight channel between adjacent walls. At this time, smoke generated by the high temperature can easily spread rapidly through these gaps. The smoke not only travels in a straight line through the gaps within the walls but also spreads into various spaces within the building, significantly impacting the safe evacuation of personnel and the conduct of fire rescue operations. Utility Model Content

[0003] To address the aforementioned shortcomings, this utility model proposes a flame-retardant and heat-insulating wall that can be installed quickly. Through the splicing structure of the upper and lower walls, as well as the splicing structure between two adjacent lower walls, smoke can be effectively blocked outside the wall, thereby effectively improving the flame-retardant and heat-insulating effect of the wall and solving the problem of poor smoke prevention effect of traditional walls.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A flame-retardant and heat-insulating quick-installation wall includes a base, an upper wall, and a lower wall; the bottom of the upper wall has a structure that is short in the middle and long at the front and back and on both sides, and the top of the lower wall has a structure that is long in the middle and short at the front and back and on both sides; the bottom of the lower wall is fixedly connected to the base, and the top of the lower wall is fixedly connected to the bottom of the upper wall.

[0006] Both sides of the lower wall are provided with stepped assembly structures, and two adjacent lower walls are spliced ​​together through the stepped assembly structures.

[0007] The upper wall includes an upper frame and an upper fireproof board assembly, with the upper fireproof board assembly installed on both the front and rear sides of the upper frame; the lower wall includes a lower frame and a lower fireproof board assembly, with the upper frame and the lower frame fixedly connected, and the lower fireproof board assembly installed on both the front and rear sides of the lower frame.

[0008] The lower surface of the upper frame abuts against the upper surface of the lower frame, the lower surface of the upper fireproof board assembly abuts against the upper surface of the lower fireproof board assembly, the bottom of the upper fireproof board assembly extends through the bottom of the upper frame, and the side of the upper fireproof board assembly abuts against the lower frame, and the top of the lower frame is located between the two upper fireproof board assemblies.

[0009] The top of the upper fireproof board assembly is flush with the top of the upper frame. The upper fireproof board assembly includes a first fireproof board and a second fireproof board. The first fireproof board is installed on both the front and rear sides of the upper frame, and the second fireproof board is provided on the side of the first fireproof board away from the upper frame.

[0010] The lower fireproof board assembly includes a third fireproof board and a fourth fireproof board; the third fireproof board is installed on both the front and rear sides of the lower frame, and the fourth fireproof board is provided on the side of the third fireproof board away from the lower frame.

[0011] The second fireproof board is longer than the first fireproof board, and the first fireproof board is longer than the upper frame; the lower frame is longer than the third fireproof board, and the third fireproof board is longer than the fourth fireproof board.

[0012] The upper frame includes an upper clamping plate and an upper keel, with the top of the upper keel fixedly connected to the bottom of the upper clamping plate. The lower frame includes a lower clamping plate and a lower keel, with the bottom of the upper clamping plate fixedly connected to the top of the lower clamping plate.

[0013] The upper keel is a stepped structure with the front side concave upward and the rear side protruding downward, and the lower keel is a stepped structure with the front side protruding upward and the rear side concave downward. The upper keel and the lower keel are fitted together.

[0014] The length of the lower fireproof panel assembly is the same as the length of the lower frame. The right end of the lower fireproof panel assembly located on the front side extends beyond the right end of the lower frame, and the right end of the lower frame extends beyond the right end of the lower fireproof panel assembly located on the rear side.

[0015] The right end of the lower wall forms a stepped assembly structure that gradually recedes from front to back, and the left end of the lower wall forms a stepped assembly structure that gradually recedes from back to front.

[0016] The right end of the fourth fireproof plate located on the front side extends beyond the right end of the third fireproof plate located on the front side.

[0017] The right end of the third fireproof plate located on the rear side extends beyond the right end of the fourth fireproof plate located on the rear side.

[0018] Both the upper and lower clamping plates are made of rock wool.

[0019] The technical solution of this utility model can include the following beneficial effects:

[0020] 1. This design specifies that the bottom of the upper wall is short in the middle and long on the front and back sides, while the top of the lower wall is correspondingly long in the middle and short on the front and back sides. This results in the joints between adjacent upper and lower walls being non-linear and staggered, preventing smoke from directly penetrating the walls. This effectively blocks the disorderly spread of smoke within the space, providing better smoke protection for the building interior and enhancing the safety of personnel in emergencies such as fires.

[0021] 2. This solution is suitable for any combination of boards and thermal insulation materials, regardless of changes in wall size or frame dimensions. Through the splicing structure between the upper and lower walls, as well as between adjacent lower walls, smoke can be effectively blocked outside the wall, thus significantly improving the wall's flame-retardant and heat-insulating properties and solving the problem of poor smoke prevention in traditional walls.

Detailed Implementation

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] In the description of this utility model, it should be understood that the terms "length", "middle", "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The following is combined Figures 1 to 4 This invention describes a flame-retardant and heat-insulating wall that can be installed quickly, according to an embodiment of the present invention.

[0032] A flame-retardant and heat-insulating quick-installation wall, characterized in that it includes a base 1, an upper wall 2, and a lower wall 3; the bottom of the upper wall 2 has a structure that is short in the middle and long on both sides, and the top of the lower wall 3 has a structure that is long in the middle and short on both sides; the bottom of the lower wall 3 is fixedly connected to the base 1, and the top of the lower wall 3 is fixedly connected to the bottom of the upper wall 2.

[0033] The lower wall 3 has stepped assembly structures on both the left and right sides, and two adjacent lower walls 3 are spliced ​​together through the stepped assembly structures.

[0034] This design specifies that the bottom of the upper wall 2 is short in the middle and long on the front and back sides, while the top of the lower wall 3 is correspondingly long in the middle and short on the front and back sides. This results in the joints between adjacent upper walls 2 and lower walls 3 being non-linear and staggered, preventing smoke from directly penetrating the space. This effectively blocks the disorderly spread of smoke within the space, providing better smoke protection for the building interior and enhancing the safety of personnel in emergencies such as fires.

[0035] Meanwhile, the stepped assembly structure on both sides of the lower wall 3 forms at least two smoke-proof steps at the joints of adjacent lower wall 3 sections. Therefore, when adjacent lower wall 3 sections are joined, a tight and tortuous gap structure is formed. When smoke encounters this special stepped joint during its dispersion, the smoke's diffusion path is significantly extended, and the tiny spaces between the gaps can impede and buffer the smoke, further effectively preventing smoke from drifting outwards through the wall joints. This creates a comprehensive, multi-layered smoke barrier inside the building, significantly improving overall smoke control performance and effectively ensuring the safety of personnel in emergency situations such as fires.

[0036] The stepped assembly structure on the left and right sides of the lower wall 3 allows for quick and precise splicing between adjacent lower walls 3, greatly reducing the reliance on complex tools and professional skills during installation, significantly improving the installation efficiency of the wall, shortening the construction cycle, and reducing labor and time costs, making it very suitable for the needs of large-scale rapid construction.

[0037] It is worth noting that this solution is suitable for any combination of boards and thermal insulation materials, regardless of changes in wall size or frame dimensions. Through the splicing structure of the upper wall 2 and lower wall 3, as well as the splicing structure between two adjacent lower wall 3 sections, smoke can be effectively blocked outside the wall, thereby significantly improving the wall's flame-retardant and heat-insulating effects and solving the problem of poor smoke prevention in traditional walls.

[0038] The upper wall 2 includes an upper frame 21 and an upper fireproof board assembly 22, with the upper fireproof board assembly 22 installed on both the front and rear sides of the upper frame 21; the lower wall 3 includes a lower frame 31 and a lower fireproof board assembly 32, with the upper frame 21 and the lower frame 31 fixedly connected, and the lower fireproof board assembly 32 installed on both the front and rear sides of the lower frame 31.

[0039] The lower surface of the upper frame 21 abuts against the upper surface of the lower frame 31, the lower surface of the upper fireproof board assembly 22 abuts against the upper surface of the lower fireproof board assembly 32, the bottom of the upper fireproof board assembly 22 extends through the bottom of the upper frame 21, and the side of the upper fireproof board assembly 22 abuts against the lower frame 31. The top of the lower frame 31 is located between the two upper fireproof board assemblies 22.

[0040] The upper frame 21 is equipped with upper fireproof board assemblies 22 on both the front and rear sides, and the lower frame 31 is equipped with lower fireproof board assemblies 32 on both the front and rear sides, forming an effective fire barrier in the wall. In the event of a fire, the fireproof board assemblies can effectively block heat transfer and flame spread, slow down the spread of fire on the wall surface, enhance the fire resistance of the wall, buy more time for the evacuation of people inside the building and for fire rescue, and further improve the fire safety performance of the building.

[0041] This embodiment ensures that the bottom of the upper wall 2 is shorter in the middle and longer on both sides, and the bottom of the lower wall 3 is longer in the middle and shorter on both sides, by defining the structure of the upper frame 21, upper fireproof board, lower frame 31, and lower fireproof board. This enhances the connection strength and stability between the upper and lower walls 3. Furthermore, the lower surface of the upper fireproof board assembly 22 abuts against the upper surface of the lower fireproof board assembly 32, and the bottom side of the upper fireproof board assembly 22 abuts against the lower frame 31. This multiple abutment structure makes the connection between the various parts of the wall tighter. When subjected to external forces, the multiple abutment structures can work together to distribute the load, reducing the risk of wall structure damage due to uneven local stress and improving the overall structural stability and reliability of the wall.

[0042] The top of the upper fireproof board assembly 22 is flush with the top of the upper frame 21. The upper fireproof board assembly 22 includes a first fireproof board 221 and a second fireproof board 222. The first fireproof board 221 is installed on both the front and rear sides of the upper frame 21. The second fireproof board 222 is provided on the side of the first fireproof board 221 away from the upper frame 21.

[0043] The lower fireproof board assembly 32 includes a third fireproof board 321 and a fourth fireproof board 322; the third fireproof board 321 is installed on both the front and rear sides of the lower frame 31, and the fourth fireproof board 322 is provided on the side of the third fireproof board 321 away from the lower frame 31.

[0044] The length of the second fireproof board 222 is longer than the length of the first fireproof board 221, and the length of the first fireproof board 221 is longer than the length of the upper frame 21; the length of the lower frame 31 is longer than the length of the third fireproof board 321, and the length of the third fireproof board 321 is longer than the length of the fourth fireproof board 322.

[0045] The upper frame 21 has first fireproof boards 221 installed on both the front and rear sides, and a second fireproof board 222 is installed on the outside of the first fireproof board 221. The lower frame 31 has a similar layout. The multi-layer fireproof board not only increases the protective performance of the wall, but also enhances its impact resistance, enabling the wall to effectively resist the forces generated by impacts, compression, and natural disasters such as earthquakes during daily use. This reduces structural deformation and damage caused by external forces, extends the service life of the wall, and lowers later maintenance costs.

[0046] It is worth noting that this application further refines the structure of the upper wall 2 and the lower wall 3. The second fireproof board 222 is longer than the first fireproof board 221, and the first fireproof board 221 is longer than the upper frame 21; the lower frame 31 is longer than the third fireproof board 321, and the third fireproof board 321 is longer than the fourth fireproof board 322. This staggered and layered length design results in an overlapping and progressively sealed structure within the wall after assembly. When smoke attempts to penetrate the wall, it must follow a more tortuous and lengthy path, greatly increasing the difficulty of smoke penetration, effectively preventing smoke from spreading between wall gaps, significantly improving the overall smoke protection performance of the wall, providing more stringent smoke protection for the building's interior space, and effectively ensuring the safety of personnel in the event of a fire.

[0047] The upper frame 21 includes an upper clamping plate 211 and an upper keel 212, with the top of the upper keel 212 fixedly connected to the bottom of the upper clamping plate 211. The lower frame 31 includes a lower clamping plate 311 and a lower keel 312, with the bottom of the upper clamping plate 211 fixedly connected to the top of the lower clamping plate 311.

[0048] The upper keel 212 is a stepped structure with the front side concave upward and the rear side protruding downward. The lower keel 312 is a stepped structure with the front side protruding upward and the rear side concave downward. The upper keel 212 and the lower keel 312 are fitted together.

[0049] The upper keel 212 is concave upwards on the front and protrudes downwards on the rear, while the lower keel 312 protrudes upwards on the front and is concave downwards on the rear, and the two fit together. This stepped structure increases the contact area and friction between the upper and lower frames 21 and 31. When subjected to external forces, such as daily impacts, minor displacements of the building structure, or vibrations caused by natural disasters like earthquakes, the fitted stepped structure can better disperse and resist external forces, making the overall wall structure more robust, enhancing the wall's earthquake and deformation resistance, extending the wall's service life, and reducing maintenance costs caused by structural damage in the later stages.

[0050] Furthermore, the stepped structure of the upper keel 212 and lower keel 312, which fit together closely, creates a tortuous and tight airflow channel inside the wall. This further extends the diffusion path of smoke, significantly increasing the difficulty of smoke leakage and further improving the smoke-proof effect of the wall structure in this solution.

[0051] Furthermore, the stepped fit between the upper keel 212 and the lower keel 312 provides construction workers with intuitive and easy-to-operate installation guidance. On the construction site, workers can quickly and accurately align and fit the upper and lower keels 312 without complicated measurement and adjustment processes. This meets the needs of rapid construction in large-scale building projects, helps to accelerate project progress, and reduces the overall construction cycle.

[0052] The length of the lower fireproof panel assembly 32 is the same as the length of the lower frame 31. The right end of the lower fireproof panel assembly 32 located on the front side extends beyond the right end of the lower frame 31, and the right end of the lower frame 31 extends beyond the right end of the lower fireproof panel assembly 32 located on the rear side.

[0053] The right end of the lower wall 3 forms a stepped assembly structure that gradually recedes from front to back, and the left end of the lower wall 3 forms a stepped assembly structure that gradually recedes from back to front.

[0054] The lower fireproof panel assembly 32 is the same length as the lower frame 31. The right end of the front lower fireproof panel assembly 32 protrudes beyond the right end of the lower frame 31, and the right end of the lower frame 31 extends beyond the right end of the rear lower fireproof panel assembly 32, resulting in the lower wall 3 having a stepped assembly structure that gradually indents from front to back and from back to front at both ends.

[0055] During construction, personnel only need to precisely align one of the stepped structures of the lower wall 3 with another corresponding part to easily complete the splicing, significantly shortening the wall installation time and greatly improving construction efficiency. This is especially in line with the urgent need for rapid wall installation in large-scale construction projects, effectively promoting project progress and significantly shortening the project construction cycle.

[0056] In addition, the stepped assembly structure can change the diffusion path of smoke on the lower wall 3, greatly extending the smoke diffusion distance, thereby strongly hindering the spread of smoke between walls, comprehensively enhancing the overall smoke prevention performance of the wall, and providing more reliable protection for the safety of people and property in a fire.

[0057] The right end of the fourth fireproof plate 322 located on the front side extends beyond the right end of the third fireproof plate 321 located on the front side;

[0058] The right end of the third fireproof plate 321 located on the rear side extends beyond the right end of the fourth fireproof plate 322 located on the rear side;

[0059] This design further defines the positions of the third fireproof board 321 and the fourth fireproof board 322, ensuring that the right end of the fourth fireproof board 322 extends beyond the third fireproof board 321 on the front side, and the right end of the third fireproof board 321 extends beyond the fourth fireproof board 322 on the rear side. This further adjusts the smoke diffusion path and significantly increases the difficulty of smoke penetration. By extending the distance smoke travels between walls, this design effectively reduces the smoke diffusion rate and further enhances the overall smoke-proof performance of the walls.

[0060] Both the upper clamping plate 211 and the lower clamping plate 311 are made of rock wool.

[0061] To enhance the smoke-proof, flame-retardant, and heat-insulating effects of the walls in this design, rock wool is used for the upper panel 211 and lower panel 311. Rock wool is an inorganic fiber material with non-combustible properties, effectively preventing the spread of fire in the event of a fire. As crucial structural components of the wall system, the use of rock wool in the upper panel 211 and lower panel 311 significantly reduces the risk of smoke generation due to panel combustion during a fire. Furthermore, the fibrous structure of rock wool has excellent adsorption properties; when smoke passes through, the rock wool panels can absorb some smoke particles and harmful gases, further improving the wall's smoke-proof effect, reducing smoke diffusion within the building, and buying more time for evacuation.

[0062] Furthermore, the right end of the second fireproof board 222 located on the front side extends beyond the right end of the first fireproof board 221 located on the front side, the right end of the first fireproof board 221 located on the front side extends beyond the right end of the upper frame 21, the right end of the upper frame 21 extends beyond the right end of the first fireproof board 221 located on the rear side, and the right end of the first fireproof board 221 located on the rear side extends beyond the right end of the second fireproof board 222 located on the rear side.

[0063] The right end of the upper wall 2 forms a stepped assembly structure that gradually recedes from front to back, and the left end of the upper wall 2 forms a stepped assembly structure that gradually recedes from back to front.

[0064] In this embodiment, the cross-section of the upper wall 2 is the same as the cross-section of the lower wall 3. When a fire occurs, the upward-blowing smoke diffuses from the front to the rear of the upper wall 2, and must successively bypass the protruding second fireproof board 222, the first fireproof board 221, the upper frame 21, the first fireproof board 221, and the second fireproof board 222. This significantly extends the diffusion path, effectively reduces the diffusion speed, reduces the amount of smoke penetrating the wall, and comprehensively improves the smoke-proof performance of the wall, providing a safer environment for people inside the building.

[0065] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
