Description

Technical Field

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

[0002] Currently, prefabricated interior partition walls are being used more and more widely in the construction industry. However, existing prefabricated interior partition walls still have three main problems:

[0003] Firstly, there is the issue of cracking: existing interior partition walls consist of several spliced ​​panel units. Adjacent panel units are fixed together using tenons and grooves and adhesive mortar. This type of interior partition wall is prone to cracking. The reason for this problem is that due to the tenon and groove structure and the limitations of the workers' construction skills, the adhesive mortar is difficult to embed and fill properly, and cannot be evenly applied to the splicing position. This results in uneven application of the adhesive mortar, and areas lacking adhesive mortar or with insufficient adhesive mortar after splicing have low connection strength and are prone to cracking.

[0004] Secondly, there is the issue of sound insulation: existing interior partitions are increasingly focused on being lightweight and easy to construct. However, because lightweight interior partitions are lighter in weight, their sound insulation performance is reduced, resulting in poor sound insulation. This is especially true for places like hotels and apartments where sound insulation is required, as it can affect the privacy of the rooms.

[0005] Thirdly, there is the issue of wiring: Most lightweight interior partition panels do not have pre-drilled conduit holes, so new grooves need to be cut into the wall when laying cables later. A few lightweight interior partition panels do have pre-drilled conduit holes, which can solve the problem of subsequent grooving of the wall panels. However, due to the large size of boxes such as multimedia information boxes and lighting distribution boxes and the dense arrangement of conduits, the conduit holes are too small and the space is limited to meet the needs of laying multiple cables.

[0006] The existing interior partition walls have problems such as wall cracking, poor sound insulation, and wiring issues, so further improvements are necessary. Utility Model Content

[0007] In order to solve the problems existing in the prior art, this utility model proposes a prefabricated lightweight interior partition wall structure.

[0008] The technical solution to the technical problem solved by this utility model is as follows:

[0009] A prefabricated lightweight interior partition wall structure includes several interlocking panel units. Each panel unit includes a sound insulation board with wire mesh on both sides. The wire mesh is spaced apart from the sound insulation board and connected to it by several positioning connectors to form an integrated structure. The structure also includes a main layer, which is embedded in lightweight concrete. The main layer is formed after the lightweight concrete solidifies. Grouting grooves are provided at both ends of each panel unit. When two adjacent panels are joined, the adjacent grouting grooves connect to form a grouting channel.

[0010] Preferably, the positioning connector includes a tube that penetrates the sound insulation board; a fixed chuck positioned on one side of the sound insulation board is fixedly connected to the tube; a movable chuck positioned on the other side of the sound insulation board is also threadedly connected to the tube; both ends of the tube are detachably connected to clamps for connecting with wire mesh, the clamps including a limiting plate and a baffle, the limiting plate being threadedly connected to the tube; the limiting plate has a groove capable of accommodating the horizontal or vertical ribs of the wire mesh; the baffle is detachably connected to the limiting plate.

[0011] Preferably, the baffle has a through hole; the limiting plate has an internal threaded hole that matches the through hole; a first bolt passes through the through hole of the baffle, and the first thread is threadedly connected to the internal threaded hole.

[0012] Preferably, the main body layer also has several sleeves with internal threads pre-embedded, and the sleeves are arranged up and down along the grouting groove; the wire mesh is welded with connecting rods, and the sleeves are fixedly connected to the connecting rods; one end of the sleeve is a closed end and the other end is an open end, and the open end is connected to the grouting groove.

[0013] Preferably, it also includes a wiring wall panel, which comprises two wall panel units, and the wiring wall panel is adapted to and spliced ​​with the strip panel unit; a wiring cavity is formed between the two wall panel units.

[0014] Preferably, a keel is vertically arranged in the wiring cavity, and the keel is connected to the strip unit by a fixing member; the fixing member includes a second bolt, the keel has several mounting holes, one end of the second bolt passes through the mounting hole, a support tube is sleeved on the second bolt, one end of the support tube abuts against one side of the keel, and the other end of the support tube abuts against the inner wall of the grouting groove; the second bolt is threadedly connected to the sleeve to fix the keel to the strip unit; the wall panel unit is fixedly connected to the keel by a self-tapping screw.

[0015] Preferably, the wall panel unit has a plurality of countersunk holes, and the head of the self-tapping screw is disposed in the countersunk holes.

[0016] Preferably, recessed portions for plastering are provided on both sides of the slat unit.

[0017] Preferably, the cross-sectional shape of the keel is "C"-shaped.

[0018] The above technical solution has the following advantages or beneficial effects:

[0043] Example 1:

[0044] like Figure 1 - Figure 8 As shown, this embodiment proposes a prefabricated lightweight interior partition wall structure, including several interlocking strip panel units E. Each strip panel unit E includes a sound insulation board 1, with wire mesh 2 on both sides of the sound insulation board 1. The wire mesh 2 and the sound insulation board 1 are spaced apart and connected by several positioning connectors 3 to form an integrated structure. It also includes a main layer, with the integrated structure embedded in lightweight concrete 4. After the lightweight concrete 4 solidifies, it forms the main layer. Grouting grooves 11 are provided at both ends of each strip panel unit E, forming a slotted structure. When two adjacent sets of strip panel units E are spliced, the adjacent grouting grooves 11 connect to form a grouting channel. By injecting grout 13 into the grouting channel, the adjacent strip panel units E can be fixedly connected. In this embodiment, the lightweight concrete 4 has the characteristics of light weight, good thermal insulation and fire resistance, and, combined with the sound insulation board 1, can effectively improve the sound insulation performance of the strip panel unit E.

[0045] In this embodiment, the positioning connector 3 described above adopts the following structure:

[0046] The positioning connector 3 includes a tube body 31 that penetrates the sound insulation panel 1. A fixed chuck 32 positioned on one side of the sound insulation panel 1 is fixedly connected to the tube body 31. A movable chuck 33 positioned on the other side of the sound insulation panel 1 is also threadedly connected to the tube body 31. The fixed chuck 32 and the movable chuck 33 can be used to clamp and fix the sound insulation panel 1. Both ends of the tube body 31 are detachably connected to clips for connecting with the wire mesh 2, which are used to position the wire mesh 2. The clips include limiting... Positioning disc 34 and baffle 35. Positioning disc 34 is threadedly connected to tube body 31. In this embodiment, both ends of tube body 31 have external thread sections, and positioning disc 34 can be threadedly connected to tube body 31. Positioning disc 34 has a groove 341 that can accommodate the horizontal or vertical ribs of wire mesh 2. Baffle 35 is detachably connected to positioning disc 34. In use, the horizontal or vertical ribs are placed in the groove 341, and then baffle 35 is installed to achieve positioning and fixing of wire mesh 2.

[0047] In this embodiment, the baffle 35 has a through hole 351; the limiting plate 34 has an internal threaded hole 342 that matches the through hole 351; a first bolt 36 passes through the through hole 351 of the baffle 35, and the first thread is threadedly connected to the internal threaded hole 342. The first bolt 36 is used to bolt and fix the baffle 35 and the limiting plate 34.

[0048] How to use positioning connector 3:

[0049] In use, one end of the tube 31 is passed through the sound insulation plate 1 until the fixed chuck 32 presses against one side surface of the sound insulation plate 1; then the movable chuck 33 is screwed on, and the movable chuck 33 presses against the other side surface of the sound insulation plate 1, completing the connection and fixation between the tube 31 and the sound insulation plate 1; then the upper limit plate 34 is screwed on at the end of the tube 31 to install the wire mesh 2, so that the horizontal or vertical ribs of the wire mesh 2 are engaged in the groove 341; then the baffle 35 is installed, and the first bolt 36 is used to fix the baffle 35 and the limit plate 34. Thus, the integrated structure is assembled.

[0050] In this embodiment, the two sides of the strip unit E are provided with recessed portions 12 for plastering. When the strip units E are spliced ​​together, the recessed portions 12 can be used to easily embed plaster and achieve grouting.

[0051] In this embodiment, the sound insulation board 1 can be made of commonly available sound insulation board materials, such as polyester fiber sound-absorbing boards; alternatively, it can be made of silicon-based micro-titanium board, a new type of green, energy-saving, and environmentally friendly product synthesized from materials such as clay, possessing properties such as heat insulation, fire resistance, moisture resistance, sound insulation, and decoration. The sound insulation board 1 can also be made of damping sound insulation board 1, which includes two sets of magnesium oxide boards 101, with a damping sound insulation felt 102 laminated between the two sets of magnesium oxide boards 101.

[0052] Application results:

[0053] By setting up sound insulation board 1, the sound insulation performance is effectively improved; and steel wire mesh 2 is arranged on both sides of sound insulation board 1. The positioning connector 3 is used to realize the fixed connection between steel wire mesh 2 and sound insulation board 1, forming a whole, which effectively increases the strength of the strip unit E and the wall is not easy to crack; the positioning connector 3 is convenient for construction and can effectively limit the steel wire mesh 2 to prevent displacement during pouring.

[0054] Example 2:

[0055] like Figure 9 - Figure 10 As shown in this embodiment, in order to further improve the connection strength between adjacent strip plate units E, several sleeves 5 with internal threads are also pre-embedded in the main body layer. The sleeves 5 are arranged up and down along the grouting groove 11. A connecting rod 6 is welded on the wire mesh 2. The connecting rod 6 can be made of steel bars. The sleeve 5 is fixedly connected to the connecting rod 6. One end of the sleeve 5 is a closed end and the other end is an open end. The open end is connected to the grouting groove 11 and can communicate with the outside.

[0056] When in use, the grouting material 13 in the grouting channel can enter the sleeve 5 to form a connecting column. As an embedded structure, it can effectively improve the connection strength and further ensure that it does not crack.

[0057] Example 3:

[0058] like Figure 11 - Figure 14 As shown, in this embodiment, based on Embodiment 1 or Embodiment 2, the prefabricated lightweight interior partition wall structure further includes a wiring wall panel 14. The wiring wall panel 14 includes two wall panel units, and the wiring wall panel 14 is adapted to and spliced ​​with the strip panel unit E for fixing. A wiring cavity is formed between the two wall panel units, which can realize the centralized arrangement of pipelines.

[0059] A vertical keel 8 is installed in the wiring cavity. The keel 8 is connected to the strip unit E by a fastener. The fastener includes a second bolt 9. The keel 8 has several mounting holes (not shown in the figure). One end of the second bolt 9 passes through the mounting hole, and a support tube 7 is sleeved on the second bolt 9. One end of the support tube 7 abuts against one side of the keel 8, and the other end abuts against the inner wall of the grouting groove 11. The second bolt 9 and the sleeve 5 are threaded together to fix the keel 8 to the strip unit E. The wall panel unit is fixedly connected to the keel 8 by a self-tapping screw 10. The support tube 7 can be made of plastic or stainless steel, etc. The support tube 7 mainly serves as a support. By tightening the second bolt 9 and the sleeve 5, the support tube 7 can be positioned, thereby achieving the connection and fixation between the keel 8 and the strip unit E.

[0060] In this embodiment, the wall panel unit has several countersunk holes 141, and the head of the self-tapping screw 10 is set in the countersunk hole 141, which is a hidden design and does not affect subsequent plastering or decoration. In this embodiment, the cross-sectional shape of the keel 8 is "U" shaped, which facilitates connection with the wall panel unit.

[0061] Application results:

[0062] By setting up the wiring wall panel 14, a wiring cavity can be easily constructed, providing a larger working space to meet the needs of centralized pipeline layout. The installation is carried out using the keel 8 and fasteners, which is a dry construction method with the advantages of fast installation speed and no dust.

[0063] Construction method of prefabricated lightweight interior partition wall structure:

[0064] First, grassroots cleanup;

[0065] Second, positioning and layout: Before construction, the baseline needs to be laid out and the horizontal line needs to be drawn out with a laser.

[0066] Third, pipe clamps are installed on the top of strip unit E;

[0067] Fourth, panel installation:

[0068] Erecting the board: After using tools to lift the board unit E, insert wooden wedges at the top and bottom of the board unit E;

[0069] Adjustment: Based on the installation control lines, adjust the planar installation position and verticality of panel unit E by adjusting the wooden wedges, thereby reducing damage to the panel caused by direct manipulation, until panel unit E is adjusted to the correct position. Check the flatness with a 2m straightedge, use a plumb bob and a 2m straightedge to check the verticality, and adjust with a rubber mallet until it meets the requirements. Then, fix the pipe clamps with a nail gun, and install in this manner.

[0070] Note: Adjacent strip unit E should be closely joined to ensure tight splicing of grouting groove 11; adjust the verticality and flatness of adjacent plate surfaces.

[0071] Fifth, fill the gap: fill the gap between the strip unit E and the floor with dry hard fine stone concrete. After removing the wooden wedges, fill the gap with dry hard fine stone concrete of the same strength and tamp it down.

[0072] Sixth, grouting: Inject grout material 13 into the top of the grouting channel;

[0073] Seventh, fill the gap: fill the gap between the strip unit E and the floor slab or beam with cement mortar, and the mortar must be full;

[0074] Eighth, joint treatment: smooth the joints between boards with crack-resistant mortar, and apply self-adhesive fiberglass mesh to the joints to prevent cracking.

[0075] Ninth, surface decoration.

[0076] 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.
