Detailed Implementation

[0060] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0061] This application provides a prefabricated wall installation structure for connecting partition walls and steel structure beams, such as... Figures 1 to 16As shown, the prefabricated wall installation structure includes a horizontal beam 1, a wall body 3, and a connecting component 2. The horizontal beam 1 and the wall body 3 are arranged vertically and both extend along a first direction. The connecting component 2 connects the horizontal beam 1 and the wall body 3. The first direction and the second direction are two mutually perpendicular directions on a horizontal plane, both perpendicular to the vertical direction. The horizontal beam 1 includes a horizontal lower flange plate 12, which is connected to the connecting component 2. The wall body 3 includes multiple wall modules 36, which are arranged sequentially along the first direction. Each wall module 36 includes a panel assembly 17, support strips 19, Z-shaped keel 21, and sound insulation and heat insulation material 20. The panel assembly 17 includes two parallel wall panels 18. There are two support strips 19, which are both arranged between the two wall panels 18 and form a cavity 22 with the panel assembly 17. The sound insulation and heat insulation material 20 is disposed within the cavity 22. The panel assembly 17 is configured with a first end 15 and a second end 16 at both ends in the first direction. A support strip 19 is disposed at the first end 15, with the end face of the support strip 19 facing away from the cavity 22 interleaved with the end faces of the two wall panels 18 at the first end 15 to form a stepped shape, constituting a first stepped surface 24. The Z-shaped keel 21 is fitted and connected to the first stepped surface 24. Another support strip 19 is disposed at the second end 16, with the end face of the support strip 19 facing away from the cavity 22 interleaved with the end faces of the two wall panels 18 at the second end 16 to form a stepped shape, constituting a second stepped surface 25. The second stepped surface 25 is configured to match the first stepped surface 24. In two adjacent wall modules 36, the first stepped surface 24 of one wall module 36 corresponds to the second stepped surface 25 of the other wall module 36, and the Z-shaped keel 21 is sandwiched between the first stepped surface 24 of one wall module 36 and the second stepped surface 25 of the other wall module 36. Multiple connecting components 2 are provided, and the multiple connecting components 2 are arranged at intervals along a first direction. Each connecting component 2 includes a fastener 6, a corner fastener 7, and a slotted fastener 9. The fastener 6 abuts against the bottom surface of the lower flange plate 12. The fastener 6 has a slot 48 at one end in a second direction, and the other end is connected to the corner fastener 7 and has a downwardly extending limiting plate 10. The fastener 6 includes a fastening plate 11 spaced apart from the lower flange plate 12. The slotted fastener 9 is connected to the fastening plate 11 and is located on the side of the fastening plate 11 facing away from the lower flange plate 12. The limiting plate 10 and the slotted fastener 9 are spaced apart in the second direction. The wall body 3 is sandwiched between the limiting plate 10 and the slotted fastener 9. One end of the lower flange plate 12 is configured to be inserted into the slot 48, and the other end is clamped between the corner fastener 7 and the fastener 6. One end of the corner fastener 7 abuts against the top surface of the lower flange plate 12, and the other end abuts against the top surface of the fastener 6. The corner fastener 7 is connected to the fastener 6 via a fastener 8, which is used to suspend one end of the fastener 6 onto the lower flange plate 12. Thus, this prefabricated wall installation structure, using a wall body 3 with support strips and Z-shaped keel, and connecting components 2, simplifies the structure while ensuring strength, and can effectively improve construction efficiency.

[0062] like Figures 3 to 8 As shown, the wall body 3 is vertical and extends along a first direction, with its length direction being the first direction, its height direction being the vertical direction, and its thickness direction being the second direction. The wall body 3 is composed of multiple wall modules 36 spliced ​​together, and the structures of each wall module 36 are identical. For a single wall module 36, it includes a panel assembly 17, a support strip 19, a Z-shaped keel 21, and sound insulation and heat insulation material 20. The panel assembly 17 includes two parallel wall panels 18. The two wall panels 18 are the same size, but their ends are not flush. The wall panels 18 are made of gypsum board, but are not limited to this; for example, the wall panels 18 can be fiber cement board or calcium silicate board. One end of the two wall panels 18 in the first direction forms a first end 15, and the other end forms a second end 16. Specifically, the two wall panels 18 can be divided into a first wall panel 26 and a second wall panel 27. The first wall panel 26 and the second wall panel 27 are separated in the second direction, and their projected portions in the second direction overlap.

[0063] For example Figures 3 to 8As shown, both support bars 19 are elongated plates, both vertically arranged, and each support bar 19 has an opening 28 extending along its length, forming a hollow structure. One support bar 19 is located at the first end 15, and the other at the second end 16. The one at the first end 15 is the first support bar, and the one at the second end 16 is the second support bar. Each support bar 19 is perpendicular to the aforementioned wall panel 18, forming a structure where one end abuts against the first wall panel 26 and the other end abuts against the second wall panel 27. The end abutting against the first wall panel 26 is the first abutting end 29, and the end abutting against the second wall panel 27 is the second abutting end 30. At the first end 15, a first wall panel 26 protrudes from the first support strip in a first direction. The first abutting end 29 of the first support strip completely abuts against the first wall panel 26, while the first support strip protrudes relative to the second wall panel 27 in the first direction. A portion of the second abutting end 30 of the first support strip abuts against the second wall panel 27, and the end of the second wall panel 27 is located near the center of the first support strip, thereby forming the aforementioned first stepped surface 24. At the second end 16, a second wall panel 27 protrudes from the second support strip in a first direction. The second abutting end 30 of the second support strip completely abuts against the second wall panel 27, while the second support strip protrudes relative to the first wall panel 26 in the first direction. A portion of the first abutting end 29 of the second support strip abuts against the first wall panel 26, and the end of the first wall panel 26 is located near the center of the second support strip, thereby forming the aforementioned second stepped surface 25. Two support strips 19 support the space between the two wall panels. These support strips 19 can be made of fiber-reinforced cement board, fiber-reinforced gypsum board, fiberglass cloth-based gypsum board, fiberglass cloth-reinforced concrete board, porous wood-plastic composite board, sawdust particleboard, straw and wood chip composite board, or wood chip laminated hollow board. The aforementioned sound insulation and thermal insulation material 20 can be mineral wool, but is not limited to this. For example, the sound insulation and thermal insulation material 20 can be glass wool, rock wool, foamed resin, foamed ceramic, foamed perlite, aluminum silicate fiber, or ceramic fiber. This sound insulation and thermal insulation material 20 is disposed within the cavity 22, adhering to one side of the wall panel 18 and spaced apart from the other wall panel 18. In this example, the sound insulation and thermal insulation material 20 is sprayed or bonded to the second wall panel 27, separating it from the first wall panel 26 to form a first gap 23. However, this is not a limitation; for example, the sound insulation and thermal insulation material 20 can be adhering to the first wall panel 26, separating it from the second wall panel 27 to form the first gap 23. In addition, the support bar 19 is connected to the wall panel 18 by screws 31. The screws 31 are driven into the wall panel 18 from the end face of the wall panel 18 facing away from the cavity 22, through the wall panel 18 and into the support bar 19.

[0064] like Figure 5 and Figure 6As shown, the Z-shaped keel 21 is a metal component, but it is not limited to this; for example, it can also be made of wood-plastic composite or other materials. The Z-shaped keel 21 includes a first straight plate 32, a second straight plate 33, and a third straight plate 34 connected in sequence. The first straight plate 32 and the third straight plate 34 are both perpendicular to the second straight plate 33 and extend to both sides of the second straight plate 33, making the cross-section of the Z-shaped keel 21 Z-shaped. The Z-shaped keel 21 is vertically arranged and located at the first end 15, forming a Z-shaped keel 21 that fits and connects with the first stepped surface 24 to improve strength. Specifically, the second straight plate 33 is configured to abut against the end face of the first support bar facing away from the cavity 22 and is connected to the first support bar by screws 31. The first straight plate 32 abuts against the end face of the first wall panel 26 facing the second wall panel 27. The third straight plate 34 is arranged at the second abutting end 30 of the first support bar and fits against the first support bar, fitting the part of the second abutting end 30 that is not covered by the second wall panel 27.

[0065] like Figures 5 to 8 As shown, when two adjacent wall modules 36 are connected, the first stepped surface 24 of one wall module 36 corresponds to the second stepped surface 25 of the other wall module 36. The two adjacent wall modules 36 are spliced ​​together, with a Z-shaped keel 21 sandwiched between the first stepped surface 24 of one wall module 36 and the second stepped surface 25 of the other wall module 36. The Z-shaped keel 21 can improve the strength of the connection between the two wall modules 36. In addition, the two adjacent wall modules 36 are also connected by fastening screws 35. The fastening screws 35 are configured to connect the Z-shaped keel 21 on one wall module 36 and the support strip 19 on the other wall module 36. One fastening screw 35 passes through the wall panel 18 and the first straight plate 32 in sequence and is driven into the support strip 19. The other fastening screw 35 passes through the wall panel 18 and the third straight plate 34 in sequence and is driven into another support strip 19, making the connection more stable. Therefore, the aforementioned Z-shaped keel 21 and support strip 19 are used together to form wall module 36, achieving self-adhesive installation. The wall module 36 is modular and standardized, suitable for industrial-scale production. Furthermore, the high-strength wall module 36 uses only one Z-shaped keel, and the cost of the support strip 19 is lower than that of the Z-shaped keel 21, saving costs. Moreover, the high structural strength of the wall module 36 facilitates its stacking, transportation, and pressure resistance. During the installation of the wall body 3, each wall module 36 is simply erected in its preset position to form a splice, and then connected with fastening screws 35, making assembly convenient.

[0066] like Figures 9 to 16As shown, all of the above-mentioned connecting components 2 are metal parts, namely, the fastener 6, corner fastener 7, and slotted fastener 9 are all metal parts, each being a single piece, but not limited to this. For example, the fastener 6, corner fastener 7, and slotted fastener 9 can be made of wood-plastic composite material, plastic material, etc. Multiple connecting components 2 are provided, and the multiple connecting components 2 are evenly spaced along the first direction. The fastener 6 mentioned above includes an upper pressure plate 38 and abutment plate 37. The abutment plate 37 is flat, and the upper pressure plate 38 and the limiting plate 10 are respectively located at both ends of the abutment plate 37 in the second direction. The limiting plate 10 is perpendicular to the abutment plate 37, and the upper pressure plate 38 and the limiting plate 10 are respectively located on both sides of the abutment plate 37. The upper pressure plate 38 is connected to the abutment plate 37 via the first connecting plate 40. The upper pressure plate 38 and the abutment plate 37 are located on the same side of the first connecting plate 40 and are perpendicular to the first connecting plate 40. The upper pressure plate 38, the first connecting plate 40, and the abutment plate 37 form the aforementioned slot 48, with the slot opening facing the angled fastener 7. Additionally, the abutment plate 37 has a protrusion 39 that protrudes towards the side extending from the limiting plate 10. The protrusion 39 includes a second connecting plate 41, a third connecting plate 42, and a fastening plate 11. The second connecting plate 41 and the third connecting plate 42 are located at opposite ends of the fastening plate 11 in the second direction and extend towards the same side of the fastening plate 11. The second connecting plate 41 and the third connecting plate 42 are perpendicular to the fastening plate 11, making the protrusion 39 U-shaped. The fastening plate 11 is connected to the abutment plate 37 via the second connecting plate 41 and the third connecting plate 42. Furthermore, the width of the limiting plate 10 (the extension length of the limiting plate 10 in the first direction) is greater than the width of the abutment plate 37 (the extension length of the abutment plate 37 in the first direction), causing the limiting plate 10 to protrude from the abutment plate 37 at both ends in the first direction. Meanwhile, the abutment plate 37 has a through hole (i.e., a first screw hole 43) on the side near the limiting plate 10 for connecting the aforementioned fastener 8.

[0067] like Figure 11 and Figure 12 As shown, the aforementioned corner fastener 7 includes a pressure plate 44 and a vertical clamping plate 45. One end of the pressure plate 44 is connected to one end of the vertical clamping plate 45, and the pressure plate 44 is perpendicular to the vertical clamping plate 45. The vertical clamping plate 45 has a limiting groove 47 at its end facing away from the pressure plate 44, and the limiting groove 47 matches the width of the abutment plate 37. In addition, the pressure plate 44 has a through hole (i.e., a first through hole 46) for the aforementioned fastener 8 to pass through. There are two first through holes 46, and they are elongated holes, but it is not limited to this. For example, the number can be one, and it can be a circular hole. The aforementioned fastener 8 is a bolt, and the aforementioned first screw hole 43 matches the thread of the bolt.

[0068] The aforementioned crossbeam 1 is an I-beam with an upper flange plate 14, a vertical plate 13, and a lower flange plate 12, which are connected in sequence to form an "I" shape, with the horizontal lower flange plate 12 at the bottom.

[0069] like Figures 9 to 13 As shown, when the corner fastener 7 and the locking fastener 6 are connected, the top surface of the abutment plate 37 abuts against the bottom surface of the lower flange plate 12, the pressure plate 44 extends along the second direction, and the lower end surface of the pressure plate 44 abuts against the upper end surface of the lower flange plate 12. The end of the vertical locking plate 45 away from the pressure plate 44 abuts against the top surface of the abutment plate 37. The bolts lock the corner fastener 7 and the locking fastener 6, so that one end of the lower flange plate 12 is clamped between the pressure plate 44 and the abutment plate 37. At the same time, the abutment plate 37 is located in the limiting groove 47, thereby limiting the corner fastener 7 and the locking fastener 6 in the first direction. In addition, there is a second gap 49 between the fastening plate 11 on the abutment plate 37 and the lower flange plate 12. The second gap 49 is 10mm to 30mm to prevent the fixing screw 31 from contacting the lower flange plate 12.

[0070] For example Figures 9 to 13 As shown, the slot 48 at the end of the fastener 6 furthest from the corner fastener 7 is inserted into the other end of the lower flange plate 12, so that end of the fastener 6 is hung on the lower flange plate 12. Thus, the prefabricated wall installation structure solves the problem of fixing the wall module 36 to the I-beam. There is no welding; the beam 1 is connected only through the fastener 6 and corner fastener 7. There are no welding precision requirements, reducing fire hazards. The components are easy and quick to install, and the installation strength is high.

[0071] like Figure 13 As shown, the aforementioned slotted fastener 9 includes a base plate 50, a first side plate 51, and a second side plate 52. The first side plate 51 and the second side plate 52 are located at opposite ends of the base plate 50 and on the same side of the base plate 50. Both the first side plate 51 and the second side plate 52 are perpendicular to the base plate 50. The first side plate 51 is wider than the second side plate 52, meaning that the dimension of the first side plate 51 in the second direction is larger than that of the second side plate 52. When the slotted fastener 9 is connected, the first side plate 51 is fitted to the fastening plate 11 and connected by screws 31. The second side plate 52 is flush with the lower end of the limiting plate 10. The wall body 3 is sandwiched between the limiting plate 10 and the base plate 50. At the same time, there is a third gap 56 between the top of the wall body 3 and the abutment plate 37, which facilitates the installation of the wall body 3. Therefore, the top of the wall module 36 is engaged by the limiting plate 10 and the slotted clip 9, and can slide appropriately along the length direction of the beam 1 (i.e., the first direction) to alleviate and avoid cracking between the wall modules 36 caused by the lateral inter-story displacement of the main steel structure under wind load.

[0072] like Figure 1 , Figure 2 , Figure 13 , Figure 16As shown, the prefabricated wall installation structure also includes a support member 5 and two ceiling decorative panels 4. The support member 5 is also a metal part, but not limited to it. The ceiling decorative panel 4 is a board with a decorative layer. The support member 5 is provided in a one-to-one correspondence with the connecting component 2. Therefore, the number of support members 5 and connecting components 2 is the same. At the same time, the structure and size of the support member 5 are the same as those of the aforementioned slotted clip 9. Specifically, the support member 5 includes a web plate 53, a first side plate 54 and a second side plate 55. The first side plate 54 and the second side plate 55 are located at both ends of the web plate 53 and on the same side of the web plate 53. The first side plate 54 and the second side plate 55 are both perpendicular to the web plate 53. The first side plate 54 is wider than the second side plate 55, that is, the dimension of the first side plate 54 in the second direction is larger than that of the second side plate 55. When the support member 5 is installed, it is located on the side of the limiting plate 10 facing away from the slotted member 9. The web plate 53 of the support member 5 is fitted to the limiting plate 10 and connected by screws 31. The second side plate 55 is flush with the second side plate 52, but is not limited to this; for example, the first side plate 54 and the second side plate 52 can also be connected. The two ceiling decorative panels 4 are located on both sides of the connecting assembly 2 in the second direction. One end of one ceiling decorative panel 4 rests on the second side plate 52 and is nailed to it with screws 31, and one end of the other ceiling decorative panel 4 rests on the second side plate 55 and is nailed to it with screws 31.

[0073] In some exemplary embodiments, an installation method is applied to the above-described prefabricated wall installation structure, including: installing fasteners 6 and corner fasteners 7, installing the wall body 3, installing support members 5, and installing ceiling decorative panels 4.

[0074] First, fasteners 6 and corner fasteners 7 are installed as a group. The number of fasteners 6 and corner fasteners 7 required for the preset connecting components 2 is determined, and each group is installed one by one. During installation of each group, fastener 6 is first placed against the bottom surface of the lower flange plate 12, with one end of the lower flange plate 12 inserted into the slot 48. Then, corner fastener 7 is installed on the side of fastener 6 with the limiting plate 10. Fastener 8 passes through the pressure plate 44 and the abutment plate 37. Fastening fastener 8 secures fastener 6 to the lower flange plate 12, just as... Figure 14 As shown.

[0075] Next, install each wall module 36 one by one. First, erect one wall module 36 and move it to the preset installation position. At this time, one side of the wall module 36 abuts against the corresponding limiting plate 10, forming the correct position, just as... Figure 15 As shown. Then, take another wall module 36, erect it, and move it to connect with the positioned wall module 36. Simultaneously, it should abut against another limiting plate 10. Secure both using fastening screws, and install slotted clips 9 on the other side of each wall module 36, as shown. Figure 16As shown, the remaining wall modules 36 are then positioned in this manner. When two wall modules 36 are joined, the end of one wall module 36 with the Z-shaped keel 21 is joined to the end of the other wall module 36 without the Z-shaped keel 21.

[0076] Next, take the support member 5 and fix it to the limiting plate 10 with screws. Each limiting plate 10 has a support member 5, so that the support member 5 and the slot card 9 correspond one to one.

[0077] Finally, ceiling decorative panels 4 are nailed onto both the support member 5 and the slotted member 9. The upper surface of the second side plate of the support member 5 and the upper surface of the second side plate of the slotted member 9 abut against the ceiling decorative panel 4. However, this is not a limitation; for example, the lower surface of the second side plate of the support member 5 and the lower surface of the second side plate of the slotted member 9 can also abut against the ceiling decorative panel 4 to accommodate the installation of different ceiling decorative panels 4.

[0078] In conjunction with the above embodiments, the prefabricated wall installation structure provided in this application is simple in structure, requires no welding, has high on-site construction efficiency, and is energy-saving and environmentally friendly. The Z-shaped keel 21 and the support strip 19 cooperate to form the wall module 36, achieving self-fitting installation. The wall module 36 is modular and standardized, suitable for industrial-scale production. Simultaneously, the high-strength wall module 36 uses only one Z-shaped keel and the low-cost support strip 19, solving the problems of stacking and transporting the wall module 36 under pressure. The prefabricated wall installation structure solves the problem of fixing the wall module 36 to the I-beam, achieving high precision without welding, reducing fire hazards, and providing simple and quick component installation with high installation strength. The top of the wall module 36 is locked in place and can slide appropriately along the length of the I-beam to alleviate and avoid cracking between the wall modules 36 caused by lateral inter-story displacement of the steel structure under wind loads.
