Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a lightweight partition wall panel and wall for prefabricated buildings. Background Technology

[0002] In the modern construction industry, lightweight partition boards, as a new type of building material, are being used more and more widely. They are mainly used for dividing interior spaces in buildings, and have significant advantages over traditional brick and stone walls.

[0003] In the traditional installation of partition walls, the conventional method is to first fix clips under the ceiling slab, then lift the wall panel unit upwards and insert it into the clips, followed by inserting wedges at the bottom to secure the wall panel unit between the clips and the floor slab. However, this fixing method relies solely on wedges for positioning, which has significant drawbacks. During installation, if a wedge is accidentally touched, the position of the wall panel unit can easily shift, requiring reinstallation and re-fixing.

[0004] Furthermore, because the wall panel units are installed from bottom to top, one person needs to hold the wall panel to determine its position, while another person is responsible for driving in and tapping the wedges to tighten them. This process is not only cumbersome, but also very laborious when manually lifting and positioning adjacent wall panel units, as they need to fit tightly together, which can easily have an adverse effect on the overall installation accuracy. Utility Model Content

[0015] Preferably, the support rail has several sets of through holes.

[0016] This utility model also proposes a wall, in which any of the above-mentioned prefabricated lightweight partition wall panels are installed between the top slab and the floor slab; wherein, the fasteners and support rails are installed on the top slab and the floor slab by means of nails; fiber mesh is attached to the joint of adjacent wall panel units and fixed by means of limiting plates; concrete is poured between the bottom of the wall panel unit and the floor slab to form a concrete base layer; the wall panel unit, the fasteners and the concrete base layer are coated with a finishing layer on both sides.

[0017] The above technical solution has the following advantages or beneficial effects:

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0038] In the description of this utility model, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0039] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this disclosure. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0040] like Figures 1 to 5As shown, this embodiment proposes a prefabricated lightweight partition wall panel, which includes fasteners 2 arranged at intervals on the upper and lower sides and a support rail 1. The fasteners 2 have a sliding track 21 inside and have an overall inverted U-shaped structure. It also includes several sets of wall panel units 3. In this embodiment, the wall panel units 3 are autoclaved lightweight aerated concrete partition wall panels (ALC partition wall panels). The wall panel units 3 have a slider 31 that can slide along the sliding track 21 on the upper side and a groove 32 that can slide along the support rail 1 on the lower side. A protrusion 33 is fixed on one side (left side) of the wall panel unit 3 and a slot 34 that can be inserted into the protrusion 33 on the other side (right side). The top of the wall panel unit 3 is fixed to the fasteners 2 and to adjacent wall panels by connectors 4.

[0041] In the conventional installation of partition walls, the usual practice is to first fix clips under the top slab, then lift the wall panel unit 3 upwards and insert it into the clips, followed by inserting wedges at the bottom to secure the wall panel unit 3 between the clips and the floor slab. However, this fixing method relies solely on wedges for positioning, which has significant drawbacks. During installation, if a wedge is accidentally touched, the position of the wall panel unit 3 can easily shift, requiring reinstallation and re-fixing.

[0042] Furthermore, since wall panel unit 3 is installed from bottom to top, one person needs to hold the wall panel to determine its position, while another person is responsible for driving in and tapping the wedges to tighten it. This process is not only cumbersome, but also very laborious to manually lift and position adjacent wall panel units 3, as they need to fit tightly together, which can easily have an adverse effect on the overall installation accuracy.

[0043] To address the problems associated with traditional partition wall panel installation, this invention employs a method where fasteners 2 and support rails 1 work together to change the installation method of the intermediate wall panel unit 3 from vertical fixation to horizontal sliding fixation. Before installation, the precise installation position is determined, and then the fasteners 2 and support rails 1 are fixed respectively. During installation, the wall panel unit 3 is smoothly pushed into the space between the fasteners 2 and support rails 1 from the side until it reaches the pre-set design position. Then, the connector 4 is used to connect the wall panel unit 3 to the top fastener 2, completing the initial positioning. Afterward, subsequent wall panel units 3 are pushed in sequentially from the side, so that the protrusions 33 of adjacent wall panel units 3 are embedded into the slots 34, fitting tightly. After fitting, the connector 4 is used to finally position the adjacent wall panel units 3.

[0044] This design significantly improves installation efficiency and accuracy. During installation, a single person can easily insert the wall panel unit 3 between the fastener 2 and the support rail 1, and use the connector 4 to position it with the fastener 2. Subsequently, as the wall panel unit 3 is continuously pushed in from the side, the coordinated action of the slot 34 and the protrusion 33 facilitates more convenient and precise positioning of adjacent wall panel units 3. The design of the support rail 1 not only effectively ensures accuracy during installation, preventing deviations in the installation position of the wall panel unit 3 due to accidental external contact, but also greatly simplifies the construction steps, achieving more efficient and precise installation.

[0045] In some embodiments, the fastener 2 has a first through hole 22 on both sides, and an installation groove 23 is provided on the outside of the first through hole 22; the slider 31 has a second through hole 35 inside. After the wall panel unit 3 is laid in place, the first through hole 22 and the second through hole 35 are connected. The connector 4 fixes the front panel unit to the bottom of the fastener 2 through the connected first through hole 22 and the second through hole 35.

[0046] In the connection scenario where the top of the wall panel unit 3 and the fastener 2 are positioned, the connector 4 includes a limiting plate 41, a threaded cylinder 42 is fixed inside the limiting plate 41, and a screwing part 44 is fixed inside the screwing part 44; wherein, the end of the threaded cylinder 42 is placed in the second through hole 35, the limiting plate 41 is engaged in the mounting groove 23 on one side of the wall panel unit 3, the end of the screw 43 is placed in the second through hole 35 and can be threadedly connected to the threaded cylinder 42, and the screwing part 44 is placed in the other mounting groove 23.

[0047] After the first through hole 22 and the second through hole 35 are connected, the threaded cylinder 42 with internal threads is installed in the second through hole 35. At this time, the limiting plate 41 and the mounting groove 23 cooperate with each other to limit the threaded cylinder 42 and prevent it from rotating. Next, the stud 43 is inserted into the first through hole 22 on the other side and installed into the threaded cylinder 42, so that the stud 43 and the threaded cylinder 42 cooperate with each other. Then, the stud 43 is rotated. Since the threaded cylinder 42 cannot rotate due to the restriction of the limiting plate 41, it will form a helical pair movement with the stud 43. This movement drives the limiting plate 41 and the screwing part 44 to move in a centered position, thereby firmly fixing them between the clamp 2 and the slider 31, realizing the positioning of the clamp 2 and the slider 31.

[0048] In some embodiments, the two outer walls of the slot 34 in the wall panel unit 3 are respectively provided with first through holes 36, and a limiting groove 37 is provided on the outer side of the first through hole 36. The protrusion 33 is provided with a second through hole 38. After the protrusion 33 of the adjacent wall panel unit 3 is inserted into the slot 34, the first through hole 36 and the second through hole 38 are connected, and the adjacent wall panel unit 3 is fixed through the first through hole 36 and the second through hole 38.

[0049] In the scenario of connecting two wall panel units 3, the connector 4 includes a limiting plate 41, a threaded cylinder 42 fixed inside the limiting plate 41, and a screwing part 44, with a stud 43 fixed inside the screwing part 44; wherein, the end of the threaded cylinder 42 is placed in the second through hole 38 and can be threadedly connected to the threaded cylinder 42, and the screwing part 44 is placed in another limiting groove 37.

[0050] After the first through hole 36 and the second through hole 38 are connected, the threaded cylinder 42 with internal threads is installed in the second through hole 38. At this time, the limiting plate 41 and the limiting groove 37 cooperate with each other to limit the threaded cylinder 42 and prevent it from rotating. With the help of the limiting plate 41, the stud 43 is inserted from the first through hole 36 on the other side and installed into the threaded cylinder 42, so that the stud 43 and the threaded cylinder 42 cooperate with each other. Then, the stud 43 is rotated. Since the threaded cylinder 42 cannot rotate due to the restriction of the limiting plate 41, it will form a helical pair movement with the stud 43. This movement drives the limiting plate 41 and the screwing part 44 to be aligned, thereby firmly fixing it between the protrusion 33 and the slot 34 between the adjacent wall panel units 3, realizing the positioning of the adjacent wall panel units 3.

[0051] Among them, the aforementioned limiting plate 41, mounting groove 23 and limiting groove 37 are all rectangular in shape. The rectangular shape can better constrain the limiting plate 41 and prevent the threaded cylinder 42 connected to it from rotating synchronously with the stud 43.

[0052] In some embodiments, a rubber strip 45 is fixed to the side edge of the limiting plate 41. The rubber strip 45 allows the limiting plate 41 to be inserted into the mounting groove 23 or the limiting groove 37, achieving a more stable positioning of the limiting plate 41. After the wall panel unit 3 is initially assembled, several sets of limiting plates 41 can be pre-inserted into the mounting groove 23 or the limiting groove 37. Then, the studs 43 are installed and tightened on the other side of the wall panel unit 3 to achieve positioning of the wall panel unit 3. This design allows only one person to independently complete all operations during the connection and positioning process, making the installation process more efficient and economical.

[0053] The connector 4 described above has the same structure for two different connection scenarios, which facilitates mass production and reduces mold costs. When connector 4 is damaged and needs to be replaced, there is no need to distinguish between different models for different scenarios; a universal connector 4 can be used for replacement, increasing the flexibility and reliability of the construction process.

[0054] In some embodiments, the connector 4 used to fix adjacent wall units has a locking groove 5 on the screwing part 44, and a locking post 6 is fitted into the locking groove 5. At least one set of limiting plates 7 for fixing the fiber mesh is connected to the outside of the locking post 6. In traditional construction processes, fiber mesh is usually bonded at the joint of two wall panel units 3 to enhance the overall structure's resistance to deformation and seismic performance. However, this method of relying solely on bonding is not very strong. During subsequent finishing layer coating operations, the fiber mesh is very likely to shift due to the external forces during construction, thereby weakening its intended reinforcement effect. Based on this, the aforementioned limiting plate 41 is used to firmly press the fiber mesh at the joint of adjacent wall units, thereby preventing displacement during subsequent construction stages.

[0055] In some embodiments, the support rail 1 has several sets of through holes 8. After the wall unit is positioned, concrete needs to be poured at its bottom to form a concrete base layer 9. The through holes 8 are designed to guide the flow of concrete slurry, so that the concrete fills the bottom and surrounding area of ​​the support rail 1 more fully.

[0056] This utility model also proposes a wall, in which the above-mentioned prefabricated lightweight partition wall panel is installed between the top slab and the floor slab. The fastener 2 and the support rail 1 are fixed to the top slab and the floor slab by nailing. Fiber mesh is attached to the joint of the adjacent wall panel unit 3 and fixed by the installed limiting piece 7. Concrete is poured between the bottom of the wall panel unit 3 and the floor slab to form a concrete base layer 9. The wall panel unit 3, the fastener 2 and the concrete base layer 9 are coated with a finishing layer on both sides.

[0057] The construction steps for this wall are as follows:

[0058] S1. According to the design drawings, measure and lay out to determine the installation position of the fastener 2 and the support rail 1, as well as the size of the wall panel unit 3. Transport the wall panel unit 3, support rail 1, fastener 2 and connector 4 of appropriate size to the construction site.

[0059] S2, the fastener 2 and the support rail 1 are fixed to the top plate and the floor plate respectively by nailing, and the protrusion 33 in the first wall panel unit 3 is cut off to ensure that the wall panel unit 3 can fit with other walls;

[0060] S3, push the first wall panel unit 3 from the side between the fastener 2 and the support rail 1, so that the slider 31 above the wall panel unit 3 is aligned with the slide rail 21 of the fastener 2 and the groove 32 below is aligned with the support rail 1, until it slides to the designed position; use the connector 4 to connect and position the top of the wall panel unit 3 to the fastener 2.

[0061] Then, the subsequent wall panel units 3 are pushed in from the side in sequence, so that the protrusions 33 of the adjacent wall panel units 3 are embedded into the slots 34 to achieve a tight fit. Then, the adjacent wall panel units 3 are positioned by the connectors 4.

[0062] S4, a fiber mesh is attached to the joint of adjacent wall panel units 3 to fix the connector 4 of adjacent wall units. The screwing part 44 has a snap-fit ​​groove 5, and the snap-fit ​​post 6 is snapped into the groove. The fiber mesh is firmly pressed at the joint by the limiting piece 7.

[0063] S5. After all wall panel units 3 are installed and positioned, a formwork is erected between the bottom of the wall panel unit 3 and the floor slab, and concrete is poured to form a concrete base layer 9. The through holes 8 on the support rail 1 can guide the flow of concrete slurry, making the concrete filling more complete.

[0064] S6. Apply a finishing layer to both sides of the wall panel unit 3, fastener 2, and concrete base layer 9 to complete the construction of the entire wall.

[0065] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
