Description

Technical Field

[0001] This application relates to the field of prefabricated wall technology, and in particular to a prefabricated composite wall assembly connection system and its application and construction method. Background Technology

[0002] Existing prefabricated houses have multiple vertical mounting holes at the bottom of the walls. Vertically installed positioning steel bars are poured into the foundation of the house, and the walls are positioned by connecting the steel bars to the vertical mounting holes. In actual construction, a crane is used to lift the wall, then the vertical mounting holes are aligned with the connecting steel bars, and the crane lowers the wall, allowing the steel bars to be inserted into the wall.

[0003] During the installation process, gaps are left between adjacent walls to facilitate installation. Furthermore, due to the inherent dimensional errors in the prefabricated walls, the size of the gaps between adjacent walls is difficult to control, resulting in large gaps that lead to poor sound insulation. Summary of the Invention

[0004] To improve sound insulation, this application provides a prefabricated composite wall assembly connection system and its application construction method.

[0005] On the one hand, the prefabricated assembled composite wall assembly connection system provided in this application adopts the following technical solution:

[0006] A prefabricated composite wall assembly connection system includes columns, a base beam, and wall panels. Multiple wall panels are arranged along the length of the base beam. A positioning part is fixedly installed on the base beam. The bottom wall of each wall panel has a positioning groove for inserting the positioning part, and an insertion groove communicating with the positioning groove. The opening of the insertion groove is larger than the opening of the positioning groove. The insertion groove and the positioning groove are arranged along the length of the wall panel. A compensating member is provided between the wall panel and the column. A sound insulation board is fixedly installed on the interior side wall of each wall panel, and the sound insulation board is used to seal the gap between adjacent wall panels.

[0007] By adopting the above technical solution, during wall panel installation, a hoist is used to lift the wall panel directly above the base beam. The wall panel is then gradually lowered so that the positioning part on the base beam inserts into the insertion slot. The wall panel is then pushed along the length of the base beam. During this process, the positioning part slides along the insertion slot and inserts into it, allowing the wall panel to abut against the adjacent, already installed wall panel, reducing the gap between adjacent wall panels. Even if there are dimensional errors in the prefabricated wall panels, it can prevent excessive gaps between adjacent wall panels. Furthermore, sound insulation panels are used to seal the gaps between adjacent wall panels, further improving the sound insulation effect.

[0008] Furthermore, the compensation component includes a compensation plate and a decorative plate. The decorative plate is disposed on the side wall of the compensation plate located on the outdoor and indoor sides. Slots are provided on the side walls of the wall panel and the column that are close to each other. Two compensation plates are provided. The compensation plate is slidably disposed along the length direction of the wall panel with a plug for inserting into the slot. The compensation plate is provided with a first elastic element for driving the plug into the slot.

[0009] Furthermore, each of the two compensation plates is fixedly provided with an installation tube along the length of the wall panel, and the insertion block is slidably disposed inside the installation tube.

[0010] Furthermore, the two compensation plates have recessed grooves on their mutually distant sidewalls. The recessed grooves are arranged along the height direction of the wall panel, and a sealing strip for contacting the wall panel or column is embedded in the recessed groove.

[0011] Furthermore, a telescopic plate is connected between the two compensation plates, and a second elastic element is provided on the telescopic plate to drive the two compensation plates away from each other. The decorative plate is slidably disposed on the compensation plate along the telescopic direction of the telescopic plate.

[0012] By adopting the above technical solution, if the wall panel vibrates due to an earthquake or other reasons, the vibration is transmitted to the compensation component, causing the expansion plate to expand and contract, so that the compensation plate always remains in close contact with the column and the wall panel; and the wall panel may shift or misalign relative to the column, which, under the action of the second elastic component, drives the compensation plate to always be in tight contact with the column or wall panel, improving the sealing and sound insulation effects.

[0013] Furthermore, the telescopic plate includes a fixed block and a connecting plate. The fixed block is disposed on the side wall of the two compensation plates that are close to each other. The fixed block has a movable groove along the length of the wall plate, and the connecting plate slides through the movable groove. The second elastic element is a spring plate disposed between the two fixed blocks, and the spring plate abuts against the side wall of the two fixed blocks that are close to each other.

[0014] Furthermore, a sliding groove is provided on the side wall of the decorative panel near the compensation plate along the length of the decorative panel, and a sliding block that is slidably connected to the sliding groove is fixedly provided on the side wall of the compensation plate near the decorative panel.

[0015] Furthermore, the compensation plate includes a first compensation block and a second compensation block, which are fixedly connected by a connecting rod. The first compensation block and the second compensation block are arranged along the thickness direction of the wall panel, and cavities are formed in the first compensation block and the second compensation block.

[0016] By adopting the above technical solution, the first compensation block and the second compensation block are separated by a connecting rod to prevent outdoor sound waves from being directly transmitted into the room through the compensation plate; and a cavity is opened in the compensation block to further improve the sound insulation effect.

[0017] Furthermore, the decorative panel is provided with sealing elements at both ends.

[0018] On the other hand, the application and construction method of the prefabricated assembled composite wall combination connection system provided in this application adopts the following technical solution:

[0019] A construction method for a prefabricated composite wall assembly connection system includes the following steps: installing columns and bottom beams, with the two ends of the bottom beams respectively abutting against the two columns;

[0020] To install the first wall panel, align one side of the first wall panel with the side wall of one of the columns, and then install the wall panels sequentially along the length of the bottom beam. When installing the wall panels, use a hoist to lift the wall panel to the top of the bottom beam, and then gradually lower the wall panel so that the positioning part on the bottom beam inserts into the insertion groove. Then push the wall panel along the length of the bottom beam until the wall panel abuts against the adjacent wall panel that has already been installed. At this point, the positioning part is inserted into the positioning groove.

[0021] After the wall panels are installed, install compensating components between the wall panels and the columns to seal the gap between them.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When installing wall panels, use a hoist to lift the wall panels to directly above the base beam, then gradually lower the wall panels so that the positioning parts on the base beam insert into the insertion slots. Then push the wall panels along the length of the base beam. During this process, the positioning parts slide along the insertion slots and insert into the slots, allowing the wall panels to abut against the adjacent installed wall panels, reducing the gap between adjacent wall panels. Even if there are dimensional errors in the prefabricated wall panels, this prevents excessive gaps between adjacent wall panels. Furthermore, sound insulation panels are used to seal the gaps between adjacent wall panels, further improving the sound insulation effect.

[0024] 2. If an earthquake or other cause causes the wall panel to vibrate, the vibration is transmitted to the compensation component, causing the expansion plate to expand and contract, ensuring that the compensation plate remains in close contact with the column and the wall panel. Furthermore, the wall panel may shift or misalign relative to the column. Under the action of the second elastic component, the compensation plate is driven to maintain tight contact with the column or wall panel, improving the sealing and sound insulation effects.

[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0033] This application discloses a prefabricated assembled composite wall assembly connection system.

[0034] Reference Figure 1 A prefabricated composite wall assembly connection system includes columns 1, bottom beams 2, and wall panels 3. Multiple wall panels 3 are arranged between adjacent columns 1, and are positioned along the length of the bottom beam 2. Compensating members 4 are provided between the wall panels 3 and the columns 1; either one column 1 has a compensating member 4 between it and the wall panel 3, or the other column 1 does not require a compensating member 4. In this embodiment, only one compensating member 4 is provided between the two columns 1. During installation, the sidewall of the wall panel 3 furthest from the compensating member 4 directly abuts against the sidewall of the column 1.

[0035] Reference Figure 1 and Figure 2A positioning part, namely a positioning block 21, is fixedly installed on the bottom beam 2. The bottom wall of the wall panel 3 has a positioning groove 31 for the positioning part to be inserted into, and the positioning block 21 is adapted to the positioning groove 31. The bottom wall of the wall panel 3 has an insertion groove 32 that communicates with the positioning groove 31. The opening of the insertion groove 32 is larger than the opening of the positioning groove 31 to facilitate the smooth insertion of the positioning block 21. The insertion groove 32 and the positioning groove 31 are arranged along the length direction of the wall panel 3. When installing the wall panel 3, the wall panel 3 is lifted to the top of the bottom beam 2 by a tower crane or other lifting equipment. Then, the insertion groove 32 of the wall panel 3 is aligned with the positioning block 21. The wall panel 3 is lowered until the positioning block 21 is inserted into the insertion groove 32. Then, the wall panel 3 is pushed to make the wall panel 3 abut against the wall panel 3 that has already been installed, thereby reducing the gap between two adjacent wall panels 3 caused by processing errors and installation gaps.

[0036] Reference Figure 3 A sound insulation panel 33 is fixedly installed on the side wall of the wall panel 3 in the room, and the sound insulation panel 33 is used to seal the gap between two adjacent wall panels 3. The side wall of the wall panel 3 in the room has an installation groove 34, and the bottom wall of the installation groove 34 has an installation slot 35, in which the sound insulation panel 33 is embedded. A connecting ear plate 36 is embedded in the installation groove 34, and both ends of the connecting ear plate 36 are fixedly connected to two adjacent wall panels 3 respectively. The connecting ear plate 36 is flush with the wall panel 3 and is fixedly connected to the wall panel 3 by fixing bolts 361.

[0037] Reference Figure 4 and Figure 5 The compensation component 4 includes a compensation plate 41 and a decorative plate 42. The decorative plate 42 is disposed on the side wall of the compensation plate 41 located on the exterior and interior sides. Two compensation plates 41 are provided. The decorative plate 42 is slidably disposed on the compensation plate 41 along the telescopic direction of the telescopic plate 7. A sliding groove 421 is formed on the side wall of the decorative plate 42 near the compensation plate 41 along the length direction of the decorative plate 42. The sliding groove 421 is a dovetail groove, and both ends of the sliding groove 421 pass through the decorative plate 42. A sliding block 411 is fixedly disposed on the side wall of the compensation plate 41 near the decorative plate 42, which is slidably connected to the sliding groove 421. The sliding block 411 is configured as a dovetail block adapted to the dovetail groove.

[0038] Reference Figure 4 and Figure 5 To improve the sealing effect, sealing elements are provided at both ends of the decorative panel 42. Specifically, dovetail grooves 422 are provided on the side walls at both ends of the decorative panel 42, and the dovetail grooves 422 are set along the height direction of the decorative panel 42, that is, along the height direction of the column 1. The sealing element is a sealing strip 5, which has a deformation cavity. An installation part 51 is integrally formed on the sealing strip 5. The installation part 51 has a dovetail-shaped cross section and is engaged in the dovetail groove 422 to achieve the installation and fixation of the sealing strip 5. The sealing strip 5 abuts against the side wall of the column 1 or the side wall of the wall panel 3.

[0039] To further improve the sealing effect, refer to Figure 4 and Figure 5 The two compensation plates 41 have a recessed groove 412 on their sidewalls that are far apart from each other. The recessed groove 412 is set along the height direction of the wall panel 3. A sealing strip 4121 for abutting against the wall panel 3 or the column 1 is embedded in the recessed groove 412. The sealing strip 4121 is a rubber strip.

[0040] Reference Figure 4 and Figure 6 Slots are provided on the sidewalls of the wall panel 3 and the column 1 that are close to each other. A plug 61 for inserting into the slot is slidably provided on the compensation plate 41 along the length of the wall panel 3. The slot extends through the top wall of the wall panel 3 and the column 1, so that the plug 61 can be smoothly inserted into the slot from the top of the column 1. An installation tube 6 is fixedly provided on each of the two compensation plates 41 along the length of the wall panel 3, and the plug 61 is slidably disposed within the installation tube 6. A first elastic element is provided on the compensation plate 41 to drive the plug 61 into the slot. The first elastic element is a compression spring 62, which is disposed within the installation tube 6. One end of the compression spring 62 abuts against the installation tube 6, and the other end abuts against the plug 61, for pushing the plug 61 to move out of the installation tube 6.

[0041] Among them, reference Figure 6 A telescopic plate 7 connects the two compensation plates 41. The telescopic plate 7 includes a fixed block 71 and a connecting plate 72. The fixed block 71 is disposed on the side wall of the two compensation plates 41 that are close to each other. The fixed block 71 has a movable groove along the length of the wall panel 3. The connecting plate 72 slides through the movable groove. The telescopic plate 7 is provided with a second elastic element for driving the two compensation plates 41 away from each other. The second elastic element is a spring plate 73. The spring plate 73 is disposed between the two fixed blocks 71 and abuts against the side wall of the two fixed blocks 71 that are close to each other.

[0042] If an earthquake or other cause causes the wall panel 3 to vibrate, this vibration is transmitted to the compensation member 4, causing the expansion plate 7 to expand and contract, so that the compensation plate 41 always remains in close contact with the column 1 and the wall panel 3; and the wall panel 3 may shift or misalign relative to the column 1. Under the action of the second elastic member, the compensation plate 41 is driven to always be in tight contact with the column 1 or the wall panel 3, improving the sealing effect and sound insulation effect.

[0043] Among them, reference Figure 4 and Figure 6The compensation plate 41 includes a first compensation block 413 and a second compensation block 414, which are fixedly connected by a connecting rod 415. The first compensation block 413 and the second compensation block 414 are arranged along the thickness direction of the wall panel 3. Cavities are formed inside the first compensation block 413 and the second compensation block 414, and multiple cavities are spaced apart along the height direction of the first compensation block 413 or the second compensation block 414 to ensure the structural strength of the first compensation block 413 and the second compensation block 414. The first compensation block 413 and the second compensation block 414 are separated by the connecting rod 415 to prevent outdoor sound waves from being directly transmitted to the room through the compensation plate 41; and the cavities inside the compensation blocks further improve the sound insulation effect.

[0044] The implementation principle of this application embodiment is as follows: When installing the wall panel 3, a hoist is used to lift the wall panel 3 to directly above the bottom beam 2, and then the wall panel 3 is gradually lowered so that the positioning part on the bottom beam 2 inserts into the insertion groove 32. Then, the wall panel 3 is pushed along the length direction of the bottom beam 2. During this process, the positioning part slides along the insertion groove 32 and inserts into the positioning groove 31, so that the wall panel 3 abuts against the adjacent wall panel 3 that has been installed, reducing the gap between the adjacent wall panels 3. Even if there are errors in the size of the prefabricated wall panel 3, it can prevent the gap between the adjacent wall panels 3 from being too large. Furthermore, the sound insulation board 33 is used to seal the gap between the two adjacent wall panels 3, further improving the sound insulation effect.

[0045] When installing the compensation component 4, the insert 61 is inserted downwards into the slot from the opening of the slot above the column 1 and the wall panel 3. The insert 61 cooperates with the slot to connect the wall panel 3 and the column 1, so that the column 1 provides a constraint force perpendicular to the wall panel 3. If the wall panel 3 vibrates due to an earthquake or other reasons, the telescopic plate 7 expands and contracts, so that the compensation plate 41 always remains in a tight position against the column 1 and the wall panel 3. Furthermore, the wall panel 3 may shift or misalign relative to the column 1. Under the action of the second elastic element, the compensation plate 41 is driven to always maintain tight contact with the column 1 or the wall panel 3, improving the sealing and sound insulation effects.

[0046] This application also discloses an application and construction method for a prefabricated composite wall assembly connection system.

[0047] A construction method for a prefabricated composite wall assembly connection system includes the following steps: installing columns 1 and bottom beams 2, with both ends of the bottom beams 2 abutting against the two columns 1 respectively;

[0048] Install the first wall panel 3, and abut one side of the first wall panel 3 against the side wall of one of the columns 1. Then install the wall panels 3 sequentially along the length of the bottom beam 2. When installing the wall panel 3, use a hoist to lift the wall panel 3 to the top of the bottom beam 2, and then gradually lower the wall panel 3 so that the positioning part on the bottom beam 2 is inserted into the insertion groove 32. Then push the wall panel 3 along the length of the bottom beam 2 until the wall panel 3 abuts against the adjacent wall panel 3 that has been installed. At this time, the positioning part is inserted into the positioning groove 31.

[0049] After the wall panel 3 is installed, a compensation component 4 is installed between the wall panel 3 and the column 1 to seal the gap between the wall panel 3 and the column 1.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
