Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, and in particular relates to a prefabricated interior wall structure. Background Technology

[0002] With the rapid development of data center construction, higher demands are being placed on the construction efficiency, space utilization, and structural stability of internal partition systems. Prefabricated integrated wall panels, due to their factory prefabrication and rapid on-site assembly characteristics, have gradually replaced traditional masonry partitions and become the mainstream solution for data center interior walls.

[0003] Existing prefabricated interior wall panels typically employ the following installation method: Pre-installed top clips are placed on the ceiling surface of the room. Each prefabricated wall panel is then erected and attached to its corresponding top clip. Adjacent prefabricated wall panels are connected via protrusions and grooves on the sides, and a small amount of mortar is applied to the joints for assembly. To temporarily secure each prefabricated wall panel, wooden wedges are inserted into the bottom; these wedges can only be removed after the mortar has completely cured.

[0004] However, this method of installing prefabricated interior wall panels has the following drawbacks: 1. Insufficient stability: Before the mortar is completely dry, the prefabricated wall panels are prone to shaking, requiring additional diagonal bracing for fixation, which occupies a lot of construction space and is prone to conflict with the electromechanical installation and other cross-operations of the data center; 2. Low construction efficiency: The erection and removal of diagonal bracing increases the number of procedures and prolongs the construction cycle, making it difficult to meet the needs of rapid delivery of the data center; 3. Waste of space: Temporary support structures obstruct passageways and equipment installation, reduce the utilization rate of construction space, and increase coordination difficulties. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, one aspect of this application proposes a prefabricated interior wall structure, comprising:

[0007] An upper fixing seat is used to fix it to the roof; the bottom surface of the upper fixing seat is provided with a downwardly protruding upper limit part;

[0008] A lower fixing base is used to fix it to the ground; the top surface of the lower fixing base is provided with an upwardly protruding lower limiting part;

[0009] A precast wall panel is provided along a horizontal first direction; an upper limit groove and a lower limit groove are respectively provided on the top and bottom surfaces of the precast wall panel; the precast wall panel is disposed between the upper fixed seat and the lower fixed seat, the upper limit part is inserted into the upper limit groove, and the lower limit part is inserted into the lower limit groove;

[0010] The lower fixed seat is divided into a first seat body and a second seat body along a second direction that is horizontal and perpendicular to the first direction, so that the lower limiting part is a first limiting part located on the first seat body and a second limiting part located on the second seat body.

[0011] The top surface of the second limiting segment is inclined relative to the horizontal plane so that the width of the second limiting segment gradually increases from top to bottom.

[0012] In this technical solution, the structural design allows for the installation of the upper and lower fixing seats first, with the precast wall installed between them. Then, the other part of the lower fixing seat is installed, thus completing the installation and fixing of the wall. During the installation process, the precast wall remains stable without the need for diagonal bracing for auxiliary fixing. This not only reduces construction steps and shortens the construction cycle but also reduces the occupation of construction space, thus avoiding conflicts with other operations and improving the utilization rate of construction space.

[0013] In some embodiments, the lower limiting portion has an isosceles triangle cross section, and the connection between the first limiting segment and the second limiting segment extends to the top of the lower limiting portion.

[0014] In the technical solution, the structural design makes the top surfaces of the first limiting component and the second limiting component inclined, so that both can be easily installed into the lower limiting groove of the precast wall; on the other hand, the isosceles triangular cross-sectional shape has good structural strength and can withstand greater pressure and shear force, thereby improving the load-bearing capacity and service life of the entire wall structure.

[0015] In some embodiments, the bottom angle of the lower limiting portion section is 25° to 30°.

[0016] In the technical solution, the structural design avoids excessive height of the lower limiting part. After the precast wall is fixed between the first body of the custom-made lower fixing seat and the lower fixing seat, the second body of the lower fixing seat can be installed between the bottom of the precast wall and the ground, and merged and connected with the first body of the lower fixing seat. This not only ensures the limiting effect of the precast wall and the installation stability of the precast wall, but also does not affect the convenience of installation and disassembly.

[0017] In some embodiments, the length of the second limiting segment in the second direction is less than or equal to half the length of the second seat segment.

[0018] In the technical solution, the structural design can reasonably control the length of the second limiting part, ensuring that the second seat part can be smoothly installed between the bottom of the precast wall and the ground, and merged and connected with the first seat part of the lower fixed seat, thus ensuring the convenience of installation and disassembly.

[0019] In some embodiments, the bottom of the first base body is provided with a fixing part extending toward the second base body; the fixing part is fixed to the ground by a grounding bolt, the grounding bolt penetrating the fixing part vertically; the top surface of the fixing part is parallel to the top surface of the second limiting body.

[0020] In the technical solution, the structural design can firmly fix the lower fixing seat to the ground and facilitate operation under the precast wall, increasing the flexibility of installation; on the other hand, the top surface of the fixing part is parallel to the top surface of the second limiting part, which can ensure that the second seat part can be smoothly installed between the bottom of the precast wall and the ground, and merge and connect with the first seat part of the lower fixing seat, ensuring the convenience of installation and disassembly.

[0021] In some embodiments, the first base body and the second base body are connected by connecting bolts arranged along a second direction.

[0022] In the technical solution, the structural design facilitates installation and disassembly, ensuring a firm and reliable connection between the first and second seat components, preventing separation or loosening during use, thereby guaranteeing the integrity and stability of the lower fixed seat.

[0023] In some embodiments, the upper limit portion and the lower limit portion are both sliding ridge structures arranged along a first direction, so that the prefabricated wall panel can slide along the first direction.

[0024] In the technical solution, the structural design enables the precast wall panel to slide along the first direction, realizing the rapid positioning and installation of the precast wall panel and improving construction efficiency; on the other hand, it increases the support surface of the precast wall panel in the second direction, improving the stability of the precast wall installation and fixing.

[0025] In some embodiments, the prefabricated wall panel has an assembly groove at one end in a first direction; the prefabricated wall panel has an assembly protrusion at the other end in the first direction, the assembly protrusion being used to insert into the assembly groove of an adjacent prefabricated wall panel.

[0026] In the technical solution, the structural design enables close connection between adjacent precast wall panels, enhancing the integrity and continuity of the wall and improving its stability. On the other hand, the plug-in connection method is easy for construction workers to operate, allowing precast wall panels to be quickly spliced ​​together, improving construction efficiency, and also facilitating partial repairs or replacements of the wall when needed.

[0027] In some embodiments, one end of the upper fixing seat in the first direction is provided with an upper connecting groove; the other end of the upper fixing seat in the first direction is provided with an upper connecting protrusion, the upper connecting protrusion being used to insert into the upper connecting groove of an adjacent upper fixing seat;

[0028] The lower fixing seat has a lower connecting groove at one end in the first direction; the lower fixing seat has a lower connecting protrusion at the other end in the first direction, and the lower connecting protrusion is used to insert into the lower connecting groove of the adjacent lower fixing seat.

[0029] In the technical solution, the structural design realizes the modular installation of the upper and lower fixed seats. Construction workers can assemble the various fixed seats together like building blocks, which improves construction efficiency and allows adjacent upper and lower fixed seats to be tightly connected, improving the connection strength of the entire wall structure and enhancing the overall stability of the wall.

[0030] In some embodiments, the upper fixing seat has the same structure as the lower fixing seat.

[0031] In the technical solution, the structural design allows the upper fixing seat to also adopt a split structure, so that during installation, one part of the upper fixing seat can be installed first, and the other part can be installed after the prefabricated wall is fixed, further improving the flexibility of wall installation.

[0047] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0048] In the description of this utility model, it should be understood that the terms "center", "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" 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.

[0049] The terms "first," "second," and "third" 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. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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.

[0051] In existing technologies, the installation of prefabricated interior wall panels typically involves pre-installing top clips on the ceiling of the building. After each prefabricated wall panel is erected, it is laterally attached to the top clips. Adjacent panels are connected via protrusions and grooves on the sides, and a small amount of mortar is applied to the joints for assembly. The joints between the top of the prefabricated wall panel and the ceiling, as well as between the bottom of the panel and the floor, are also filled with mortar. Wooden wedges are inserted between the bottom of the panel and the floor to temporarily secure it; these wedges are removed only after the mortar has completely cured. Because precast wall panels are prone to wobbling before the mortar is completely dry, diagonal braces are usually installed on one side of the precast wall panels for auxiliary fixation in order to maintain their upright position and prevent them from tipping over. However, these diagonal braces occupy a lot of construction space and are prone to conflict with other operations such as electromechanical installation in data centers, obstructing passageways and equipment installation, reducing the utilization rate of construction space, and increasing coordination difficulties. On the other hand, the erection and removal of diagonal braces increases the number of procedures and prolongs the construction cycle, making it difficult to meet the needs of rapid delivery of data centers.

[0052] like Figures 1 to 8 As shown in the schematic embodiment of the prefabricated interior wall structure of this utility model, the prefabricated interior wall structure includes a fixing seat and a prefabricated wall panel.

[0053] The mounting base includes an upper mounting base 1 and a lower mounting base 2. The upper mounting base 1 is fixed to the inner top surface of the roof of the house, and the lower mounting base 2 is fixed to the ground inside the house. The bottom surface of the upper mounting base 1 is provided with a downwardly protruding upper limit part 11, and the top surface of the lower mounting base 2 is provided with an upwardly protruding lower limit part 21.

[0054] The top and bottom surfaces of the precast wall panel 3 are respectively provided with an upper limit groove 31 and a lower limit groove 32. The upper limit part 11 is inserted into the upper limit groove 31, and the lower limit part 21 is inserted into the lower limit groove 32, so that the precast wall panel 3 is stably installed between the upper fixed seat 1 and the lower fixed seat 2.

[0055] The lower fixing base 2 is divided into a first base body 201 and a second base body 202 along a second direction that is horizontal and perpendicular to the first direction. The lower limiting part 21 is divided into a first limiting part 211 located on the first base body 201 and a second limiting part 212 located on the second base body 202. Thus, while dividing the lower fixing base 2 into two parts, the lower limiting part 21 is also divided into two parts. The top surface of the second limiting part 212 is inclined relative to the horizontal plane, so that the width of the second limiting part 212 gradually increases from top to bottom.

[0056] During installation, the upper fixing seat 1 is fixed to the roof, and the first seat body 201 of the lower fixing seat 2 is fixed to the ground. The precast wall panel 3 is moved to the lower part of the upper fixing seat 1 with an inclination relative to the horizontal plane. The upper limit part 11 of the upper fixing seat 1 is inserted into the upper limit groove 31 at the top of the precast wall panel 3. The precast wall panel 3 is flipped vertically. During the flipping process, the upper limit part 11 is gradually inserted deeper into the upper limit groove 31. At the same time, the height of the bottom end of the precast wall panel 3 gradually decreases and moves to the top of the first seat body 201. Since the width of the first limiting part 211 is much smaller than the width of the lower limiting groove 32, and the upper limit part 11 is gradually inserted deeper into the upper limit groove 31, the height of the top end of the precast wall panel 3 gradually increases, reducing the speed at which the bottom end of the precast wall panel 3 descends. This allows the bottom end of the precast wall panel 3 to move to the top of the first seat body 201, thereby allowing the first limiting part 211 on the first seat body 201 to gradually insert into the lower limiting groove 32. When the precast wall panel 3 is flipped to the vertical position, the upper limit part 11 is fully inserted into the upper limit groove 31, and the first limiting part 211 is fully inserted into the lower limiting groove 32. Then, by rotating and translating, the second seat part 202 is sent into the space between the bottom end of the precast wall panel 3 and the ground, and the second limiting part 212 enters the remaining space of the lower limiting groove 32. The first seat part 201 and the second seat part 202 are connected to form a lower fixed seat 2, which stably limits and fixes the bottom of the precast wall, thus completing the installation of the prefabricated interior wall.

[0057] The top surface of the second limiting segment 212 is tilted so that the top of the second limiting segment 212 is on the side of the second seat segment 202 facing the first seat segment 201. When the second seat segment 202 is sent into the space between the bottom end of the precast wall panel 3 and the ground, the second limiting segment 212 enters first and gradually moves upward into the lower limiting groove 32 as it rotates. At the same time, the main body of the second seat segment 202 enters the space between the bottom end of the precast wall panel 3 and the ground.

[0058] During installation, this structural design ensures the stability of the precast wall in the second direction through the insertion connection between the upper limit part 11 and the upper limit groove 31, and the insertion connection between the first limiting part 211 and the lower limiting groove 32. Simultaneously, the first base part 201 can be vertically constructed into a precast wall, maintaining its vertical stability. This allows the first base part 201 of the upper fixing seat 1 and lower fixing seat 2 to stably fix the precast wall. Subsequently, the second base part 202 of the lower fixing seat 2 is installed, ultimately achieving stable installation of the precast wall. During installation, the precast wall does not require auxiliary fixation with diagonal braces, thus eliminating the need for diagonal brace installation and disassembly, and eliminating the construction space occupation caused by diagonal braces. This avoids conflicts between wall installation and other cross-operations such as electromechanical installation in the data center, allowing various construction tasks to be carried out simultaneously and in an orderly manner, shortening the construction cycle and meeting the needs of rapid data center delivery.

[0059] Furthermore, the upper limit portion 11 typically matches the upper limit groove 31, such that after the upper limit portion 11 is inserted into the upper limit groove 31, it completely fills the internal space of the upper limit groove 31. Similarly, the lower limit portion 21 typically matches the lower limit groove 32, such that after the lower limit portion 21 is inserted into the lower limit groove 32, it completely fills the internal space of the lower limit groove 32. This structural design ensures a secure connection between the top and bottom ends of the precast wall, enhancing the constraint of the connection on the precast wall and improving its stability.

[0060] In some embodiments, the lower limiting portion 21 has an isosceles triangle cross-section, and the connection between the first limiting segment 211 and the second limiting segment 212 extends to the top of the lower limiting portion 21. This structural design ensures that after the isosceles triangle cross-section is split, each of the first limiting segment 211 and the second limiting segment 212 has a triangular cross-section. The top surfaces of both the first limiting segment 211 and the second limiting segment 212 are inclined surfaces, and both gradually increase in width from top to bottom, making the tops of the first limiting segment 211 and the second limiting segment 212 relatively sharp. This facilitates insertion into the lower limiting groove 32 of the precast wall, improving the convenience of precast wall assembly. In addition, the isosceles triangle cross-sectional shape has good structural stability and strength, and can withstand greater pressure and shear force, thereby improving the lower fixing seat 2's ability to support the precast wall, and further enhancing the load-bearing capacity and service life of the entire wall structure.

[0061] In some embodiments, the base angle of the lower limiting part 21 is 25° to 30°, that is, the base angle of the isosceles triangle formed by the cross-section of the lower limiting part 21 is 25° to 30°. This structural design avoids the lower limiting part 21 from being too high, thereby avoiding the second seat part 202 with the second limiting part 212 from being too high. This ensures that the second seat part 202 of the lower fixing seat 2 can be smoothly inserted between the bottom of the precast wall and the ground, realizing its merging and connection with the first seat part 201 of the lower fixing seat 2. At the same time, it also ensures the limiting and fixing effect of the lower limiting part 21 on the insertion of the precast wall, ensuring the installation stability of the precast wall, without affecting the convenience of installation and disassembly of the second seat part 202.

[0062] In some embodiments, the length of the second limiting segment 212 in the second direction is less than or equal to half the length of the second seat segment 202. This structural design can reasonably control the length of the second limiting segment 212, avoiding the second limiting segment 212 being too long and increasing the external dimensions of the second seat segment 202, ensuring that the second seat segment 202 of the lower fixing seat 2 can be smoothly inserted between the bottom end of the precast wall and the ground, realizing its merging and connection with the first seat segment 201 of the lower fixing seat 2, while also ensuring the limiting and fixing effect of the lower limiting part 21 on the insertion of the precast wall, ensuring the installation stability of the precast wall, and not affecting the convenience of installation and disassembly of the second seat segment 202.

[0063] In some embodiments, the bottom of the first seat body 201 is provided with a fixing part 22 extending toward the second seat body 202, such that the fixing part 22 extends in the second direction and protrudes relative to the first seat body 201. The second seat body 202 is provided with a receiving groove 23 for accommodating the fixing part 22. When the second seat body 202 and the first seat body 201 are combined and connected to form the lower fixing seat 2, the fixing seat enters the receiving groove 23, so as to avoid the fixing part 22 from obstructing the combination of the second seat body 202 and the first seat body 201.

[0064] The fixing part 22 is fixed to the ground by a grounding bolt 4, which penetrates vertically through the fixing part 22. During installation, the first base body 201 can be left unfixed initially. When the precast wall is flipped to the vertical position, the first base body 201 can be moved synchronously, keeping it directly below the bottom of the precast wall. After the precast wall is flipped to the vertical position, the bolt holes on the fixing base are exposed in the space between the ground and the bottom of the precast wall, making it easy to tighten the grounding bolt 4 in the fixing part 22 and fix the first base body 201 to the ground.

[0065] The top surface of the fixing part 22 is parallel to the top surface of the second limiting part 212, so that the top of the fixing part 22 avoids the second seat part 202 from being screwed into the space between the ground and the bottom of the precast wall, ensuring that the second limiting part 212 of the second seat part 202 can be smoothly inserted into the lower limiting groove 32.

[0066] This structural design, through the setting of the fixing part 22, allows the lower fixing seat 2 to be firmly bolted to the ground, and the bolt rotation can be operated in the space between the bottom of the precast wall and the ground, making installation and disassembly convenient. It also provides an alternative method for wall installation, ensuring that the first seat component 201 can be smoothly fixed to the bottom of the precast wall, and the first limiting component 211 can be smoothly inserted into the lower limiting groove 32, increasing installation flexibility. Furthermore, the inclined top surface of the fixing part 22 avoids the second seat component 202, allowing it to be smoothly installed between the bottom of the precast wall and the ground, and merged and connected with the first seat component 201 of the lower fixing seat 2, ensuring ease of installation and disassembly.

[0067] In some embodiments, the first base body 201 and the second base body 202 are connected by connecting bolts 5 arranged along a second direction. This structural design ensures a firm and reliable connection between the first base body 201 and the second base body 202, preventing separation or loosening during use and guaranteeing the integrity and stability of the lower fixing seat 2. Secondly, the connecting bolts 5, being arranged along the second direction, can act as an internal support structure, enhancing the stability of the lower fixing seat 2 and thus improving the stability of the precast wall. Furthermore, the connecting bolts 5 can be installed and removed laterally without obstruction from other wall structures, improving the convenience of installation and removal.

[0068] In some embodiments, both the upper limit portion 11 and the lower limit portion 21 are sliding ridge structures arranged along a first direction, allowing the prefabricated wall panel 3 to slide along the first direction. The prefabricated interior wall is typically installed starting from the inner surface of one side wall of the room. First, a first set of upper fixing seats 1 and lower fixing seats 2 can be installed. The first prefabricated wall panel can be slidably installed between the first set of upper fixing seats 1 and lower fixing seats 2 along the first direction and attached to the side wall of the room, without the need for separate installation of the lower fixing seat 2. Subsequently, the installation of the upper fixing seats 1 and lower fixing seats 2 is followed by sliding the prefabricated wall panels along the first direction until the prefabricated interior wall reaches the side wall of the other side of the room. The installation of the last prefabricated wall panel 3 is carried out using a separate installation method for the lower fixing seat 2, i.e., first installing the first body 201 of the upper fixing seat 1 and lower fixing seat 2, then installing the prefabricated wall, and finally installing the second body 202 of the lower fixing seat 2. This structural design allows the precast wall panel 3 to slide along the first direction, thereby sliding into the space between the upper fixed seat 1 and the lower fixed seat 2, achieving rapid positioning and installation of the precast wall panel 3 and improving construction efficiency. Furthermore, the upper limit part 11 is positioned along the length of the upper fixed seat 1, and the lower limit part 21 is positioned along the length of the lower fixed seat 2, increasing the length of the upper limit part 11 and the lower limit part 21. This increases the length of the top and bottom insertion connection portions of the precast wall panel 3, thereby increasing the constraint and fabrication of the insertion connection on the precast wall panel 3 in the second direction, and improving the stability of the precast wall panel 3 in the second direction after installation and fixation.

[0069] In some embodiments, one end of the prefabricated wall panel 3 in a first direction is provided with an assembly groove 33, and the other end of the prefabricated wall panel 3 in the first direction is provided with an assembly protrusion 34. The assembly protrusion 34 of one prefabricated wall panel 3 is inserted into the assembly groove 33 of an adjacent prefabricated wall panel 3, so that the various prefabricated wall panels 3 of the prefabricated interior wall are interlocked. This structural design allows adjacent prefabricated wall panels 3 in the prefabricated interior wall to be tightly connected, enhancing the integrity and continuity of the wall and improving its stability. Secondly, the interlocking connection method is convenient for construction personnel to operate, enabling the prefabricated wall panels 3 to be quickly spliced ​​together, improving construction efficiency, and also facilitating partial repairs or replacements of the wall when needed. In addition, the prefabricated wall panels 3 can support each other. When the last prefabricated wall panel 3 is installed in the prefabricated interior wall and the second base body 202 of the lower fixing seat 2 is not installed, the first base body 201 and the adjacent prefabricated wall panel 3 can ensure the stability of the last prefabricated wall panel 3 in the second direction. This allows the installation of the second base body 202 to proceed smoothly without considering the stability of the last prefabricated wall panel 3.

[0070] In some embodiments, one end of the upper fixing seat 1 in the first direction is provided with an upper connecting groove 12, and the other end of the upper fixing seat 1 in the first direction is provided with an upper connecting protrusion 13. The upper connecting protrusion 13 of one upper fixing seat 1 is inserted into the upper connecting groove 12 of the adjacent upper fixing seat 1, so that the various upper fixing seats 1 of the prefabricated interior wall are inserted into each other.

[0071] The lower fixing seat 2 has a lower connecting groove 24 at one end in the first direction and a lower connecting protrusion 25 at the other end in the first direction. The lower connecting protrusion 25 of one lower fixing seat 2 is inserted into the lower connecting groove 24 of the adjacent lower fixing seat 2, so that the lower fixing seats 2 of the prefabricated interior wall are inserted into each other.

[0072] The modular installation of the upper fixed seat 1 and the lower fixed seat 2 allows construction workers to assemble the various fixed seats together like building blocks, improving construction efficiency. It also enables a tight connection between adjacent upper fixed seats 1 and lower fixed seats 2, improving the connection strength of the entire wall structure and enhancing the overall stability of the wall.

[0073] In some embodiments, the structure of the upper fixing seat 1 is the same as that of the lower fixing seat 2, meaning that the upper fixing seat 1 also adopts a split structure, and the upper limit part 11 is also divided into two parts. This structural design allows for the selection of first installing the entire lower fixing seat 2 and a part of the upper fixing seat 1, and then installing the other part of the upper fixing seat 1 after the precast wall is fixed between the two. This achieves stable installation of the precast wall when it is inconvenient to assemble the two parts of the lower fixing seat 2 from the bottom, further improving the flexibility of wall installation operations.
