Description

Technical Field

[0001] This invention relates to the field of building materials technology, specifically to a prefabricated partition wall and its construction method. Background Technology

[0002] Lightweight partition wall panels are a new type of energy-saving wall material. They resemble hollow floor slabs in appearance, but feature tongue and groove joints on both sides. Installation is simple: just stand the panels upright, apply a small amount of jointing mortar to the tenons, and then assemble them. They are composed of harmless phosphogypsum, lightweight steel slag, fly ash, and other industrial waste residues, cured under variable frequency steam pressure. Lightweight partition wall panels offer advantages such as light weight, high strength, multiple environmental benefits, thermal insulation, sound insulation, humidity regulation, fire resistance, rapid construction, and reduced wall construction costs. The inner layer contains a rationally arranged layer of heat-insulating and sound-absorbing inorganic foam profiles or other insulation materials. The wall panels are manufactured through a streamlined process of pouring, leveling, and scientific curing, resulting in a high degree of automation and a wide variety of specifications.

[0003] In existing technologies, lightweight partition walls inside buildings mostly use panel partition walls or frame partition walls. Panel partition walls are inconvenient to construct, and the joints and seams generally require a period of curing before subsequent construction can proceed; frame partition walls have complex procedures and are more complicated to control deformation. These partition walls have long construction cycles and complicated procedures, and when no longer needed, they can generally only be demolished, making them difficult to modify and reuse. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a prefabricated partition wall and its construction method, solving the problems existing in the prior art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated partition wall, comprising a filler, a cavity panel, and a caulking material. The cavity panel includes two side panels, with a closed web and a void web provided between the two side panels. The cavity panel is integrally formed, and the void web has holes. The filler extends out from the outermost void web corresponding to the outer side of the closed web, and the extension length of the filler at the outermost void web is the same as the extension length of the side panel at the outer side of the closed web, so as to splice and fix the transverse units. The cavity panel is divided into several equal-sized cavities in the middle by the void web to ensure the integrity and continuity of the filler.

[0008] The filler and cavity panel are prefabricated in batches in the factory to form a block unit. The specific size can be flexibly adjusted on site as needed. The front and rear outer surfaces of the side panels are treated before leaving the factory to meet actual decoration requirements.

[0009] Preferably, the hole is a rounded hole.

[0010] Preferably, there are gaps above and below all the openings in the web between the cavity panel and the filler, so that the filler can slide up and down when an external force is applied.

[0011] Preferably, the length of the side panel extending outward from the closed web, the thickness of the closed web or the open web, and the lateral length of the small cavity are added together to equal the length of a single cavity in the middle, so that different layers of blocks can be spliced ​​in a staggered manner.

[0012] A construction method for a prefabricated partition wall, comprising the prefabricated partition wall described above, is as follows:

[0013] When manufacturing the blocks, determine the dimensions of each part according to actual needs, and determine the sliding height of the infill (same as the gap height between the infill and the cavity panel) according to the height requirements of the floor and skirting board.

[0014] During construction, fill the gaps in the web with infill blocks, allowing them to slide downwards and be placed sequentially at the locations where the walls should be installed. After one layer is installed, the second layer is inserted into the upper recess of the first layer, offset from the first. Repeat the above steps until the filling reaches near the top of the wall. Measure the height of the opening, cut the unit, and then fill the gap.

[0015] If pipelines are to be installed, the layout can be done in advance, and holes can be drilled in the infill material and cut into the cavity panel. For corners and tops, the block units should be cut, filled, and fixed as needed. After filling all joints with caulking material, the wall surface can be decorated according to actual decorative requirements.

[0016] When making changes, you can remove the additional decorations and caulking materials, then remove the blocks one by one from top to bottom and reuse them.

[0017] (III) Beneficial Effects

[0018] This invention provides a prefabricated partition wall and its construction method. It has the following beneficial effects:

[0019] This prefabricated partition wall and its construction method utilize factory-prefabrication into a single block unit, which can be flexibly adjusted on-site as needed. During use, the infill material is pressed to misalign with the cavity panel, allowing for rapid wall assembly. This invention solves the problems of long construction cycles, cumbersome procedures, difficulty in modification, and reusability associated with existing lightweight partition walls. The wall construction is simple and quick, with high control precision, and is easily reusable, resulting in significant economic benefits. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-4 This invention provides a technical solution: a prefabricated partition wall, comprising a filler 1, a cavity panel 2, and a caulking material 3. The cavity panel 2 includes two side panels 21, with a closed web 22 and a hollow web 23 disposed between the two side panels 21. The cavity panel 2 is integrally formed, and the hollow web 23 has holes. The filler 1 extends out from the outermost hollow web 23 corresponding to the outer side of the closed web 22. The extension length of the filler 1 at the outermost hollow web 23 is the same as the extension length of the side panel at the outer side of the closed web 22, so as to splice and fix the transverse units. The hollow panel 2 is divided into several equal-sized cavities in the middle by the hollow web 23 to ensure the integrity and continuity of the filler 1.

[0029] The infill 1 and the cavity panel 2 are prefabricated in batches in the factory to form a block unit. The specific size can be flexibly adjusted on site as needed. The front and rear outer surfaces of the side panel 21 are treated before leaving the factory to meet actual decoration requirements.

[0030] The hole has rounded corners.

[0031] There are gaps above and below all the openings in the web between the cavity panel 2 and the filler 1, and the filler 1 can slide up and down when an external force is applied.

[0032] The side panel 21 extends beyond the closed web 22 by a length equal to the length of a single cavity in the middle, and the thickness of the closed web 22 or the open web 23 is added to the transverse length of the small cavity, allowing different layers of blocks to be staggered and spliced.

[0033] A construction method for a prefabricated partition wall, comprising the aforementioned prefabricated partition wall, is described in the following steps:

[0034] When manufacturing the blocks, determine the dimensions of each part according to actual needs, and determine the sliding height of the filler and the gap height between the filler and the cavity panel according to the height requirements of the floor and skirting board.

[0035] During construction, press down on the filling block 1 at the 23rd position of the empty web plate to make the filling block 1 slide downwards and place it in sequence at the location where the wall should be placed. After placing one layer, the second layer is inserted into the upper recess of the first layer in a staggered manner. Repeat the above steps to fill to near the top of the wall. Measure the height of the opening and cut the unit before filling the plug.

[0036] If pipelines are to be installed, the layout can be done in advance, and holes can be drilled in the infill material 1 and cut to leave holes in the cavity panel 2. The corners and tops can be cut, filled, and fixed as needed. After filling all joints with caulking material 3, the wall surface can be decorated as needed.

[0037] When making changes, after removing the additional decorations and grout material 3, you can remove the blocks one by one from top to bottom and reuse them.

[0038] The prefabricated partition wall of the present invention includes a filler, a cavity panel, and a caulking material. The filler and the cavity panel are prefabricated in batches in the factory to form an independent unit, which can be flexibly adjusted on site as needed.

[0039] The filler can be made from recycled materials for green recycling, and has good thermal insulation, sound insulation, fire resistance, mildew resistance and insect resistance.

[0040] The cavity panel is divided into several equal-sized cavities by a hollow web to ensure the integrity and continuity of the filling material.

[0041] All cavity openings in the cavity panel are rounded to ensure the filling degree of the filler.

[0042] There are gaps above and below all the openings in the web between the cavity panel and the filler. Applying external force can cause the filler to slide up and down.

[0043] After the cavity panel and the filler slide up and down, the protruding and retracted parts between the upper and lower units can be spliced ​​and fixed.

[0044] The length of the side panel extending from the closed web, the thickness of the closed web, the open web, and the transverse length of the small cavity are added together to equal the length of a single cavity in the middle, so that different layers of blocks can be staggered and spliced. The front and rear outer surfaces of the side panel 21 are treated before leaving the factory to meet actual decorative requirements.

[0045] The cavity panel is lightweight and has sufficient friction with the infill material, so it will not slip between itself and the infill material due to its own weight.

[0046] The front and rear surfaces of the cavity panel are treated before leaving the factory to meet actual decorative requirements.

[0047] The caulking material can be structural sealant or similar materials to ensure the sealing of the gaps and the flatness and stability of the wall surface.

[0048] In summary, this prefabricated partition wall and its construction method utilize factory-prefabrication into a single block unit, which can be flexibly adjusted on-site as needed. During use, the infill material is pressed to misalign with the cavity panel, allowing for rapid wall assembly. This invention solves the problems of long construction cycles, cumbersome procedures, difficulty in modification, and reusability associated with existing lightweight partition walls. The wall construction is simple and quick, with high control precision, and is easily reusable, resulting in significant economic benefits.
