Description

Technical Field

[0001] This utility model relates to the field of cast-in-place foamed concrete wall technology, and in particular to a cast-in-place foamed concrete PVC skeleton composite wall. Background Technology

[0002] Cast-in-place foamed concrete PVC-framed composite walls are a new type of building envelope system. Its core structure involves pouring lightweight foamed concrete onto a pre-assembled PVC formwork frame system on-site. This system uses a PVC mold shell as a permanent formwork, with an internal lightweight steel frame for structural support. The entire wall is formed by pouring in foamed concrete, which has thermal insulation properties. However, existing cast-in-place foamed concrete PVC-framed composite walls still suffer from problems such as low strength of the internal support frame, complex frame installation, and the inability to form a robust outer shell.

[0003] Therefore, it is essential to invent a cast-in-place foamed concrete PVC skeleton composite wall. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a cast-in-place foamed concrete PVC-framed composite wall, which solves the issues of low internal support frame strength, complex frame installation, and inability to form a robust outer shell in existing cast-in-place foamed concrete PVC-framed composite walls. The cast-in-place foamed concrete PVC-framed composite wall includes corner support shells, support plates, a central frame, a first grouting plate, and a second grouting plate. The support plates are fixedly installed on both sides of the central frame, and the corner support shells are fixedly installed on the outside of four sets of support plates. The first and second grouting plates are located on the outside of the corner support shells.

[0005] The central frame includes a longitudinal support beam, a transverse support beam, mounting holes, and a reinforcing frame. The longitudinal support beam is fixedly installed at both ends of the transverse support beam, and support plates are fixedly installed at both ends of the longitudinal support beam. The mounting holes are opened inside the transverse support beam, and the reinforcing frame is fixedly installed inside the mounting holes.

[0006] The first grouting plate includes a wall support plate, a wall pier support plate, a cover concrete plate, and a side concrete plate. The wall support plate is fixedly installed between two sets of wall pier support plates, and the cover concrete plate is bonded to the inner surface of the wall support plate. The side concrete plate is bonded to the inner surface of the wall pier support plate.

[0007] The transverse support beam inside the central frame is a single PVC rod, and the transverse support beam is horizontally supported in the middle of the wall by the longitudinal support beam. There are two sets of mounting holes; each set of mounting holes has several holes; the mounting holes face two different directions, and the reinforcing frame is made of several PVC rods, which are tilted in two directions through the mounting holes with different orientations.

[0008] The internal structures of the first and second grouting plates are completely identical and mirror images of each other. After the first and second grouting plates are joined, they can form a cylindrical structure in the shape of a wall. The covering concrete plate and the side concrete plate are made of two sets of rolled concrete plates. When the first and second grouting plates are demolded, the covering concrete plate and the side concrete plate are separated from the wall support plate and the wall pier support plate and cover the outer surface of the wall.

[0009] Compared with the prior art, the present invention has the following beneficial effects: The central frame of this utility model is set up to form a lateral force resisting truss by obliquely fixing the frame through the mounting holes, which jointly bears the vertical and horizontal loads; its two ends are connected to the support plates and anchored to the corner support shell to ensure overall stability, while constraining the pouring space formed by the first pouring plate and the second pouring plate to ensure the molding accuracy and structural strength of the cast-in-place foamed concrete.

[0010] The first grouting plate of this invention, when combined with the second grouting plate in a mirror image, forms a sealed pouring cavity, ensuring the precise molding of the cast-in-place foamed concrete. Its core structure consists of a rigid outer frame formed by wall support plates and wall pier support plates, which, together with the inner lining concrete plate and side concrete plates, form a composite enclosure system. This system serves both as a formwork for the construction phase and as a permanent decorative protective layer after demolding. Attached Figure Description

[0015] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. 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 should fall within the protection scope of the present invention.

[0016] As attached Figure 1 To be continued Figure 3 As shown.

[0017] This utility model provides a cast-in-place foamed concrete PVC skeleton composite wall, including a corner support shell 1, a support plate 2, a central skeleton 3, a first grouting plate 4, and a second grouting plate 5, wherein: the support plate 2 is fixedly installed on both sides of the two ends of the central skeleton 3, and the corner support shell 1 is fixedly installed on the outside of the four sets of support plates 2, and the first grouting plate 4 and the second grouting plate 5 are arranged on the outside of the corner support shell 1.

[0018] The central frame 3 includes a longitudinal support beam 31, a transverse support beam 32, mounting holes 33, and a reinforcing frame 34. The longitudinal support beam 31 is fixedly installed at both ends of the transverse support beam 32, and support plates 2 are fixedly installed at both ends of the longitudinal support beam 31. The mounting holes 33 are opened inside the transverse support beam 32, and the reinforcing frame 34 is fixedly installed inside the mounting holes 33.

[0019] The first grouting plate 4 includes a wall support plate 41, a wall pier support plate 42, a cover concrete plate 43, and a side concrete plate 44. The wall support plate 41 is fixedly installed between two sets of wall pier support plates 42. The cover concrete plate 43 is bonded to the inner surface of the wall support plate 41. The side concrete plate 44 is bonded to the inner surface of the wall pier support plate 42.

[0020] The transverse support beam 32 inside the central frame 3 is a single PVC rod, and the transverse support beam 32 is horizontally supported in the middle of the wall by the longitudinal support beam 31. There are two sets of mounting holes 33; each set of mounting holes 33 has several holes; the mounting holes 33 face two different directions, and the reinforcing frame 34 is made of several PVC rods, and the reinforcing frame 34 is tilted in two directions by the mounting holes 33 with different orientations.

[0021] The internal structures of the first grouting plate 4 and the second grouting plate 5 are completely identical and mirror images of each other. After the first grouting plate 4 and the second grouting plate 5 are joined together, they can form a cylindrical structure in the shape of a wall. The covering concrete plate 43 and the side concrete plate 44 adopt two sets of rolled concrete plates. When the first grouting plate 4 and the second grouting plate 5 are demolded, the covering concrete plate 43 and the side concrete plate 44 are separated from the wall surface support plate 41 and the wall pier support plate 42 and cover the outer surface of the wall.

[0022] This cast-in-place foamed concrete PVC frame composite wall system adopts a construction method combining modular prefabrication and on-site casting. A stable steel structure load-bearing system is formed by the central frame 3, support plates 2, and corner support shells 1, providing core support for the wall. The first and second pouring plates 4 and 5 are mirror-closed to form a standardized pouring cavity. The wall surface support plate 41 and wall pier support plate 42 serve as the outer mold boundary, while the covering concrete plate 43 and side concrete plates 44 form the inner mold interface, ensuring dimensional accuracy during the foamed concrete pouring process. The oblique arrangement of the reinforcing frame 34 effectively controls concrete flow, while the mounting holes 33 of the transverse support beams 32 facilitate pipeline pre-embedding.

[0023] This system achieves rapid construction and performance optimization through efficient collaboration between factory prefabrication and on-site construction. After pouring, when the outer formwork is removed, the covering concrete slab 43 and the side concrete slabs 44 are permanently bonded to the cast-in-place layer, forming a surface layer that combines protection and decoration. The central frame 3 and the hardened concrete together constitute a combined load-bearing system, while the corner support shell 1 provides the building connection interface, ultimately forming a high-performance wall that integrates structural support, thermal insulation, and decorative functions. The entire process combines the stability of steel structures, the precision of formwork systems, and the integrity of cast-in-place concrete, significantly improving construction efficiency and building quality.

[0024] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
