Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a method for constructing curved decorative walls. Background Technology

[0002] Building wall construction is a crucial part of building engineering, mainly referring to the construction of the vertical enclosure or partition structure of a building through standardized processes. The construction process typically includes key steps such as base treatment, positioning and layout, material preparation (e.g., blocks, concrete, or lightweight panels), wall masonry / pouring, mortar joint treatment, and the installation of structural columns and ring beams. Modern construction must strictly adhere to the masonry principles of "horizontal and vertical alignment, full mortar, and staggered joints," and comprehensively utilize seismic structural measures such as steel mesh and tie bars. With technological advancements, prefabricated wall construction is becoming increasingly common, improving efficiency through factory prefabrication and on-site assembly. The quality of wall construction directly affects the building's load-bearing capacity, sound and heat insulation effects, and durability. During construction, it is necessary to simultaneously consider the pre-embedding of water and electricity pipelines, reinforcement of door and window openings, and other coordinated work to ultimately form a complete building envelope system that meets design strength and verticality requirements.

[0003] Curved decorative walls are widely used in the construction industry, but traditional construction methods have obvious limitations: fixed supports are difficult to adapt to complex curvature changes, resulting in insufficient shape accuracy; after concrete pouring, cracks are prone to occur due to stress concentration; the construction process relies on customized molds, which is costly and time-consuming; in the existing technology, it is difficult to balance structural strength and shape freedom by using precast curved components or on-site manual shaping, especially in the construction of large-span curved walls, there are common problems such as poor stability of the formwork support system, inaccurate positioning of steel bars, and poor concrete forming effect, which affect the durability and aesthetics of the decorative wall. Summary of the Invention

[0004] To address the shortcomings of existing methods, this invention provides a construction method for curved decorative walls, thereby solving the problems mentioned in the background art regarding the poor adaptability of supports, insufficient shaping accuracy, poor formwork stability during large-span construction, and unsatisfactory forming effect in traditional curved wall construction.

[0005] To solve the above problems, the present invention provides the following technical solution: a method for constructing curved decorative walls, comprising the following steps: Install anchoring components on the foundation wall: embed anchoring components on the surface of the foundation wall, and fix the anchoring components to the foundation wall by anchoring rods on the back of the steel plate base; Install the adjustable support device: Fix the flange of the adjustable support device to the front of the steel plate base, adjust the position of the movable sleeve of the adjustable support device according to the required wall curvature, adjust the adjustable support device to the support length and lock it with the fastening nut; Installing prestressed steel reinforcement components: Horizontal steel bars are tied to the fixing plate on the outer surface of the movable sleeve rod by binding steel bars, and then longitudinal steel bars are installed along the trajectory of the horizontal steel bars, and fixed at the intersection of the steel bars by fixing nodes; Install the curved formwork system: Install the inner and outer formwork along the curved contour of the prestressed steel reinforcement assembly; Pouring concrete: Pouring concrete between the inner and outer formwork to form a curved concrete wall; Demolding and post-treatment: After the concrete has cured, the formwork is removed and a surface decoration layer is installed on the surface of the concrete wall.

[0006] Preferably, the anchor rod is welded to the back of the steel plate base, and the front of the steel plate base is welded with a mounting screw, the outer surface of which is threaded with a mounting nut.

[0007] Preferably, the outer surface of the flange is provided with mounting holes, the mounting screw passes through the mounting holes, and the flange is fixed to the front of the steel plate base by the mounting screw and the mounting nut.

[0008] Preferably, a support rod is welded to the middle of the outer surface of the flange, the movable sleeve is sleeved on the end of the support rod away from the flange, the fastening nut is threaded to the outer surface of the support rod, and the fastening nut is located outside the movable sleeve.

[0009] Preferably, a connecting plate is welded to the end of the support rod away from the flange, and the outer surface of the connecting plate is fitted inside the movable sleeve rod.

[0010] Preferably, the fixing plate is welded to the outer surface of the movable sleeve rod, and the outer surface of the fixing plate has a reinforcing bar through hole, through which the binding reinforcing bar passes.

[0011] Preferably, a limiting ring is welded to the inner surface of the movable sleeve, and the limiting ring is linearly arranged along the inner surface of the movable sleeve.

[0012] This invention provides a method for constructing curved decorative walls. It offers the following advantages: 1. This method for constructing curved decorative walls achieves high-precision dynamic adjustment of the curvature of the curved surface by using the telescopic cooperation between the movable sleeve rod and the support rod of the adjustable support device, combined with the linear guidance of the limit retaining ring and the rigid locking of the fastening nut. This solves the problem that traditional fixed supports are difficult to adapt to complex curvature changes.

[0013] 2. The construction method of this curved decorative wall uses prestressed steel reinforcement components. The horizontal and vertical steel reinforcements form a spatial stress grid through fixed nodes. Prestress is applied before concrete pouring, which effectively disperses the structural load and inhibits shrinkage cracks, significantly improving the crack resistance and long-term durability of the curved wall.

[0014] 3. The construction method for this curved decorative wall surface uses a modular design of anchoring components, adjustable support devices and template system to replace customized mold construction with a standardized installation process, which greatly shortens the construction period and reduces the overall cost, while ensuring the structural stability and decorative completion of the large-span curved surface.
