Description

Technical Field

[0001] This utility model belongs to the field of stepped concrete wall formwork, specifically relating to a stepped combined assembly formwork for cantilever retaining walls. Background Technology

[0002] The riverbank embankment reinforcement project primarily utilizes an I-beam structure underground erosion control wall for the underground portion, while the above-ground structure employs a capped beam tie plate and cantilever retaining walls. The cantilever retaining wall design considers structural stability, aesthetic quality, and harmony with the existing ancient embankment (Eighteen Steps) structure. It employs a stepped structure with steps every 50cm, featuring 5cm horizontal joints and 2cm recessed joints along the axial direction, and 2cm longitudinal recessed joints along the height direction. The recessed joints are not aligned, creating a staggered tiered effect. (See attached diagram.) Figure 1 , Figure 2 As shown.

[0003] In conventional construction methods, steel formwork is used, and scaffolding is erected on both sides of the wall. The formwork is heavy, difficult to operate, risky, and difficult to install and dismantle. Using wooden formwork has problems such as time-consuming on-site material cutting, easy damage, low turnover rate, and low construction efficiency.

[0004] Based on the design concept, in order to solve the problems of misalignment, horizontal concave joints, and vertical concave joints, and to ensure construction quality, it is urgent to develop a cantilever retaining wall facade formwork that is easy to process, has reliable stress resistance, and is conducive to on-site construction. Utility Model Content

[0005] This utility model aims to solve the problem of difficult formwork support for stepped concrete walls.

[0006] This utility model provides the following technical solution: a stepped modular assembly template for a cantilever retaining wall, comprising a composite material wall template and metal transition rods; rows of composite material wall templates are connected by metal transition rods; the composite material wall templates are used at the straight sections of the cantilever retaining wall, and the metal transition rods are used at the stepped sections of the cantilever retaining wall; the composite material wall templates connected to the metal transition rods are staggered to form a stepped structure, and a horizontal protrusion is constructed on one side of the metal transition rod located within the mold cavity.

[0007] Furthermore, the composite wall template and the metal adapter rod are connected by a quick-release handle; the top and bottom surfaces of the metal adapter rod have slots with narrow entrances and wide interiors, and the side ribs of the composite wall template have through holes; the locking head of the quick-release handle passes through the through holes and engages with the slots.

[0008] Furthermore, the metal adapter rod is hollow inside, with a reinforcing plate connecting the bottom slot to the top plate, and a reinforcing plate connecting the top slot to the bottom plate.

[0009] Furthermore, vertical pressure strips are installed on the molded surface of the composite material wall template.

[0010] Furthermore, the slot extends along the length of the metal adapter rod.

[0011] Furthermore, the metal adapter rod is an aluminum alloy rod.

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0023] like Figure 3 , Figure 4 , Figure 5 As shown: A stepped modular assembly template for a cantilever retaining wall includes a composite material wall template 3 and a metal transition rod 4; rows of composite material wall templates 3 are connected by the metal transition rod 4; the composite material wall template 3 is used at the straight sections of the cantilever retaining wall, and the metal transition rod 4 is used at the stepped sections of the cantilever retaining wall. The composite material wall templates 3 connected by the metal transition rod 4 are staggered to form a stepped structure, and a horizontal protrusion 4.1 is constructed on one side of the metal transition rod 4 located inside the mold cavity.

[0024] The composite material wall formwork 3 is made of modified polypropylene resin (PP) and continuous glass fiber, forming a shaped flat mold. The metal adapter rod 4 is an aluminum alloy rod. Both the composite material wall formwork 3 and the aluminum alloy adapter rod are high-strength materials, facilitating on-site operation, easy installation and dismantling, and improving construction efficiency. The composite material wall formwork 3 and the aluminum alloy adapter rod are lightweight, minimizing the risk of workers performing high-altitude operations. By using the composite material flat mold and adapter rod for connection, the composite material flat mold can be reused in other locations, improving material utilization.

[0025] like Figure 6 As shown: The composite material wall template 3 and the metal adapter rod 4 are connected by a quick-release handle 5; the top and bottom surfaces of the metal adapter rod 4 have slots 4.2, which are narrow at the entrance and wide inside; the side ribs of the composite material wall template 3 have through holes 3.1; the locking head of the quick-release handle 5 passes through the through hole 3.1 and engages in the slot 4.2. The locking head of the quick-release handle 5 is inserted into the slot 4.2 through the through hole 3.1 in a horizontal position, and then rotated 90°. At this time, the locking head of the quick-release handle 5 changes to a vertical position, and the locking point of the locking head engages in the wide part of the slot 4.2. The quick-release handle 5 tightens and fixes the composite material wall template 3 and the metal adapter rod 4.

[0026] The metal adapter rod 4 is hollow inside. The bottom groove 4.2 is connected to the top plate by a stiffening plate 4.3, and the top groove 4.2 is connected to the bottom plate by a stiffening plate 4.3.

[0027] The slot 4.2 runs through the length of the metal adapter rod 4, allowing the composite material wall template 3 to freely change its fixed position on the metal adapter rod 4.
