Description

Technical Field

[0001] This utility model relates to the field of building partition technology, and in particular to a steel frame partition. Background Technology

[0002] Currently, partition walls are widely used in construction projects to separate interior spaces, especially in projects such as hotels and apartments, where partition walls in damp areas such as bathrooms need to have high waterproof performance and durability.

[0003] Existing bathroom partition walls mostly use traditional masonry structures, such as brick walls or lightweight block walls. While these walls are sturdy, they are generally thick and heavy, occupying valuable building space and increasing structural load. Their construction is often wet work, with complicated procedures and long construction periods. More importantly, their waterproofing performance depends entirely on the later waterproofing layer, which is prone to failure at the wall-to-floor junction and corners due to stress concentration or improper construction, leading to leaks and difficult repairs. Another common approach is to use lightweight partition walls with a light steel frame and waterproof gypsum board or cement fiberboard. While this type of partition is easy to construct and thin, its durability, sound insulation, and sturdiness often fall short in long-term damp environments. Once the waterproofing layer is damaged, moisture intrusion can cause a decline in the performance of the boards, corrosion of the frame, and mold growth. Furthermore, in batch construction, quality control of waterproofing is difficult, making standardized operations challenging and leaving potential problems for project quality.

[0004] Therefore, there is an urgent need in this field for a new partition wall technology solution, especially suitable for waterproof partition walls that are constructed in batches, such as hotel bathrooms. This solution should be able to simplify and standardize the construction process, and while effectively reducing the wall thickness, significantly improve the overall rigidity, waterproof reliability and long service life of the partition wall. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steel frame partition wall. To achieve the above objective, the embodiments of this utility model adopt the following technical solution: This utility model embodiment proposes a steel frame partition wall, comprising: a main frame, the main frame including two or more sets of longitudinal skeletons, the upper and middle sections of the longitudinal skeletons being provided with snap-fit ​​members opposite each other, multiple sets of ALC strips being provided between the longitudinal skeletons and being snap-fitted by snap-fit ​​members, the bottom section of the main frame being located within a cast-in-place structure with reinforcing ribs, the cast-in-place structure being connected to the ground; and sequentially covering the outside of the main frame are an interface agent layer, a reinforced mortar base layer, a polymer cement waterproof layer, a waterproof protective layer, an adhesive layer, and a rock slab decorative surface layer, wherein the interface agent layer, the reinforced mortar base layer, the polymer cement waterproof layer, the waterproof protective layer, the adhesive layer, and the rock slab decorative surface layer extend towards the ground.

[0006] Preferably, the main frame further includes a transverse frame, which is connected to the longitudinal frame, and the bottom end of the longitudinal frame is fixed to the ground by expansion bolts; wherein, the transverse frame is located above the ceiling surface.

[0007] Preferably, one end of the horizontal frame is fixed to the wall with expansion bolts, and the top of the vertical frame is fixed to the top surface with expansion bolts.

[0008] Preferably, transverse ribs are provided between the ALC strips, and a plaster layer is filled between two longitudinally adjacent groups of ALC strips and the transverse ribs.

[0009] Preferably, a metal mesh is embedded between the interface agent layer and the reinforced mortar base layer.

[0010] Preferably, the diameter of the metal wires in the metal mesh is 0.7 mm to 0.9 mm, and the mesh opening diameter is 8 mm x 8 mm to 15 mm x 15 mm.

[0011] Preferably, on the outside of the cast structure, an additional reinforced waterproof layer is provided between the polymer cement waterproof layer and the waterproof protective layer. The reinforced waterproof layer is a JS self-adhesive waterproof layer, and the laying height of the JS self-adhesive waterproof layer is 1000mm to 1500mm extending upward from the finished surface of the ground.

[0012] Preferably, the thickness of the reinforcing mortar base layer is 20mm to 25mm; the thickness of the polymer cement waterproof layer is 1.5mm to 2.0mm; the thickness of the waterproof protective layer is 10mm to 15mm; the thickness of the adhesive layer is 5mm to 8mm; and the thickness of the slab decorative surface layer is 12mm to 15mm.

[0013] Preferably, the thickness of the ALC strip is 40mm to 60mm.

[0014] Beneficial effects: This utility model provides a steel frame partition wall. By setting up a main frame composed of a longitudinal skeleton, ALC panels, and snap-fit ​​connectors, with its bottom section placed within a reinforced cast-in-place structure, and simultaneously applying multiple layers of waterproofing and decorative coatings to the outside of the main frame, it effectively overcomes the shortcomings of traditional masonry partition walls, such as their heaviness, slow construction, and susceptibility to waterproofing failure, as well as the insufficient rigidity and susceptibility to moisture damage of lightweight keel partition walls. Compared with existing technologies, this utility model achieves standardized, modular, and rapid installation of the partition wall by assembling the longitudinal skeleton and ALC panels using snap-fit ​​connectors. This significantly improves the efficiency and consistency of batch construction and overcomes the problems of cumbersome construction procedures and difficult quality control in traditional methods. Furthermore, this structure, with a steel frame as the main body, combined with thin ALC panels and a rock slab decorative surface layer, significantly reduces the overall thickness of the partition wall while ensuring high rigidity and strength, effectively saving building space. This solution not only improves the construction efficiency and waterproofing reliability of the partition wall but also significantly enhances the rigidity, durability, and space utilization of the structure.

[0019] Example Please see Figures 1 to 6 The steel frame partition wall 10 proposed in this embodiment is particularly suitable for hotel bathrooms or other waterproof partition wall scenarios requiring batch construction. The steel frame partition wall 10 includes a steel cantilever frame, with its core structure being a main frame 11. For example... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the main frame 11 includes two or more sets of longitudinal skeletons 111. These longitudinal skeletons 111, as the main load-bearing components of the wall, are usually made of shaped steel (such as square steel pipes or channel steel) to ensure sufficient rigidity and strength. The longitudinal skeletons 111 are set vertically, with their bottom ends firmly fixed to the ground 20 by expansion bolts, and their top ends connected to the upper structure.

[0020] In the upper middle section of the longitudinal frame 111, snap-fit ​​connectors 112 are arranged in pairs opposite each other. For example... Figure 4 As shown, these snap-fit ​​connectors 112 are used for installing and securing the ALC panels 113. Multiple sets of ALC panels 113 (autoclaved aerated concrete panels) are provided between adjacent longitudinal frames 111. The ALC panels 113 are a lightweight, fire-resistant, and sound-insulating wall material. These ALC panels 113 are securely snapped and fixed between the longitudinal frames 111 using the snap-fit ​​connectors 112, quickly forming the main body of the wall.

[0021] Preferably, such as Figure 4As shown, to further enhance the connection and integrity between the ALC panels 113, horizontal reinforcing bars 117 are provided between the ALC panels 113 in the horizontal direction. At the joints between two longitudinally adjacent (i.e., vertically adjacent) sets of ALC panels 113 and the horizontal reinforcing bars 117, a plaster layer 118 is used to fill the gaps. This design not only strengthens the connection between the panels but also ensures the flatness of the wall surface.

[0022] Preferably, the thickness of the ALC panel 113 can be between 40mm and 60mm. This thickness range ensures the panel's own strength and sound insulation performance while helping to achieve an ultra-thin wall, thereby effectively saving building space, and is particularly suitable for compact bathrooms.

[0023] like Figure 1 and Figure 4 As shown, a key structural element of this embodiment lies at the base of the wall. The bottom section of the main frame 11 is housed within a cast-in-place structure 115. This cast-in-place structure 115 is typically constructed on-site from concrete or high-strength mortar, and contains reinforcing ribs 114 to enhance its crack resistance and load-bearing capacity. The cast-in-place structure 115 is integrated with the ground surface 20 (structural layer), forming a robust, waterproof base or "reverse curb." After the bottom end of the longitudinal frame 111 is fixed to the ground surface 20 or the cast-in-place structure 115 using expansion bolts, it is either connected to or encased by the top of the cast-in-place structure 115, thereby achieving extremely high structural stability and root sealing.

[0024] like Figure 1 and Figure 6 As shown, to achieve a high level of waterproofing and decorative effect, multiple functional layers are sequentially covered on the main frame 11 (mainly referring to the outer surface of the ALC panel 113). These functional layers include: The interface agent layer 12 is first applied to the surface of the ALC strip 113 to enhance the adhesion of subsequent coatings and seal the capillaries of the ALC strip. The reinforcing mortar base layer 13 is applied over the interface agent layer 12. The polymer cement waterproof layer 14 is applied over the reinforcing mortar base layer 13 and serves as the main waterproof barrier for the wall. The waterproof protective layer 15 is applied over the polymer cement waterproof layer 14 to protect the waterproof layer from damage during subsequent construction. The adhesive layer 16 is applied over the waterproof protective layer 15 for bonding the finishing material. The slab decorative surface layer 17, as the outermost decorative layer, is fixed by the adhesive layer 16. These covering layers not only cover the main body of the wall but also extend downwards to the ground 20, seamlessly connecting with the outer side of the cast-in-place structure 115, forming a continuous and complete waterproof and decorative system from the wall to the ground.

[0025] To further improve the stability and durability of the structure, this embodiment also includes the following preferred solutions: Preferably, such as Figure 4 and Figure 5 As shown, the main frame 11 also includes a transverse frame 116. The transverse frame 116 is connected to the longitudinal frame 111 by welding or bolting to form a stable steel grating frame. In particular, the transverse frame 116 is preferably located above the ceiling surface 30, i.e., within the ceiling space. This design allows the load-bearing frame of the partition wall to extend above the ceiling, more effectively resisting lateral impacts and deformation. It also provides sufficient space for the ALC strip 113 to be installed from top to bottom, facilitating its snap-fit ​​into the snap-fit ​​member 112.

[0026] Preferably, to make the connection between the main frame 11 and the main building structure more secure, one end of the transverse frame 116 can be fixed to the adjacent (load-bearing) wall with expansion bolts, and the top of the longitudinal frame 111 can be fixed to the top surface (i.e., the upper floor slab) with expansion bolts. This multi-point anchoring method makes the entire steel frame partition wall 10 an extremely stable steel structure cantilever frame.

[0027] Preferably, such as Figure 6 As shown, to prevent cracks in the reinforced mortar base layer 13 due to temperature changes or drying shrinkage, a metal mesh 119 is embedded between the interface agent layer 12 and the reinforced mortar base layer 13. This metal mesh 119 serves to strengthen the crack-resistant structure and ensure the integrity and smoothness of the base layer.

[0028] More preferably, the wire diameter of the metal mesh 119 is 0.7 mm to 0.9 mm, and the mesh opening diameter is 8 mm x 8 mm to 15 mm x 15 mm. This specification of metal mesh has been proven in practice to have the best crack resistance and ease of construction, and can effectively disperse stress.

[0029] Preferably, such as Figure 1 As shown, considering that the base of the wall is the weakest point in waterproofing, an additional reinforcing waterproof layer 18 is provided inside the waterproof protective layer 15 on the outside of the cast-in-place structure 115. This reinforcing waterproof layer 18 is preferably a JS self-adhesive waterproof layer (a composite of a polymer cement waterproof coating and a self-adhesive roll material, or specifically a self-adhesive coating), which provides double protection.

[0030] More preferably, the JS self-adhesive waterproof layer 18 is laid 1000mm to 1500mm above the finished floor surface (non-structural floor 20). This height covers all water splash areas in a typical shower area, greatly improving the waterproof safety factor in high-humidity areas and fundamentally preventing root leakage.

[0031] Preferably, in order to achieve the best construction quality and functional effect, the thickness of each functional layer has also been optimized and limited: The thickness of the reinforcing mortar base layer 13 is preferably 20mm to 25mm to ensure sufficient strength and effective bonding of the metal mesh 119. The thickness of the polymer cement waterproof layer 14 is preferably 1.5mm to 2.0mm to form a dense, continuous, and somewhat elastic waterproof membrane. The thickness of the waterproof protective layer 15 is preferably 10mm to 15mm to provide effective protection for the underlying waterproof layer. The thickness of the adhesive layer 16 is preferably 5mm to 8mm, which is an ideal thickness for bonding large-format slabs such as sintered stone. The thickness of the sintered stone decorative surface layer 17 is preferably 12mm to 15mm, balancing aesthetics, durability, and weight.

[0032] The construction steps of the steel frame partition wall 10 in this embodiment are roughly as follows: According to the design positioning, the longitudinal frame 111 is installed on the ground 20 and fixed with expansion bolts.

[0033] Install a horizontal frame 116 above the ceiling surface 30 (and at the required location), and firmly connect it with the vertical frame 111 and the main building structure (walls and ceiling) to form the main frame 11.

[0034] A reinforcing rib 114 is installed at the bottom section of the main frame 11.

[0035] Concrete or high-strength mortar is poured on site to form a cast structure 115 that wraps around the bottom of the longitudinal skeleton 111 and connects to the ground 20.

[0036] After the poured structure 115 has cured to the required strength, ALC strips 113 are installed between the longitudinal skeletons 111 and fixed with clips 112. Transverse reinforcement bars 117 are then installed as needed, and the joints are filled with plaster 118.

[0037] Apply an interface agent layer 12 to the surface of ALC strip 113.

[0038] Lay the metal mesh 119 and apply the reinforcing mortar base layer 13 to the specified thickness (20-25mm) to ensure flatness.

[0039] After the reinforcing mortar base layer 13 has dried, apply the polymer cement waterproof layer 14 to the specified thickness (1.5-2.0 mm).

[0040] At the base of the wall, i.e. on the outside of the cast-in-place structure 115, an additional reinforced waterproof layer 18 (JS self-adhesive waterproof layer) is constructed, with a height of 1000-1500mm.

[0041] Apply a waterproof protective layer to the specified thickness (10-15mm), taking care to protect the completed waterproof layer.

[0042] Apply adhesive layer 16 (5-8mm) onto waterproof protective layer 15.

[0043] Lay the decorative slab surface layer 17 to complete the wall construction.

[0044] In summary, this embodiment achieves lightweight, high-strength, high-efficiency construction, and extremely high waterproof reliability of the partition wall through the coordinated design of steel frame structure, lightweight ALC strips, root casting structure, and multi-layer composite waterproof decorative layer, perfectly solving the pain points of the existing technology.
