Description

Technical Field

[0001] This utility model relates to the field of building formwork, specifically to a single-sided support structure for carbon fiber formwork. Background Technology

[0002] In construction, for projects such as large-volume concrete pouring, underground garages, retaining walls, subway stations, tunnels, and water conservancy and hydropower projects, where walls can only be constructed on one side or cannot be reinforced with tie rods, single-sided formwork is typically required. Currently, conventional single-sided formwork usually uses steel panels and single-sided support structures. Steel panels are prone to rusting during use, leading to reduced flatness; while single-sided support structures usually require on-site welding, resulting in low construction efficiency, and the welded structure is inconvenient to transport and hoist, with low reuse rate. Summary of the Invention

[0003] To address the technical shortcomings of low construction efficiency and low reusability of single-sided formwork structures in existing technologies, this utility model provides a carbon fiber formwork single-sided formwork structure that is easy to assemble, adaptable to any single-sided formwork construction scenario, and reusable.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A carbon fiber formwork single-sided support structure includes a carbon fiber formwork and a single-sided support structure. The single-sided support structure includes secondary ribs, main ribs, bottom rods, trusses, and diagonal braces. Each of the main ribs, bottom rods, trusses, and diagonal braces is composed of at least one segment of double C-shaped beam unit. The C-shaped beam unit is modularly designed to allow the main ribs, bottom rods, trusses, and diagonal braces to be freely combined to the required length dimensions. Modular hole structures are provided on the C-shaped beams and E-shaped beams to achieve arbitrary distance connections between the main ribs, secondary ribs, bottom rods, trusses, and diagonal braces.

[0006] In another embodiment, the secondary beam is an E-shaped beam with a trapezoidal cross-section, including a lower base side (i.e., one side of the lower base edge of the trapezoid), an upper base side (i.e., one side of the upper base edge of the trapezoid), and a side waist (i.e., one side of the waist of the trapezoid).

[0007] In another embodiment, the double C-beam unit includes two C-beams and end plates disposed at both ends of the two C-beams; the end plates are provided with holes. When several double C-beam units need to be connected, the end plates of the double C-beam units can be overlapped and aligned with the holes and then fixed with bolts.

[0008] In another embodiment, the secondary ribs are arranged horizontally on the carbon fiber template; the main ribs are arranged vertically on the secondary ribs; the bottom rod is set on the ground, with one end abutting the main rib and perpendicular to the carbon fiber template; the truss is connected to the main ribs and the bottom rod; one end of the diagonal brace is connected to the truss, and the other end is connected to the bottom rod.

[0009] In another embodiment, the truss includes longitudinal beams, diagonal beams, and chords; the chords are arranged parallel to the main beams and connected at their lower ends to the bottom beams; one end of the longitudinal beam is connected to the main beam and the other end is connected to the chord, and the longitudinal beam is perpendicular to the main beam and the chord; at least one diagonal beam is also provided between the diagonal beam and the bottom beam and between the longitudinal beams, one end of the diagonal beam being connected to the main beam and the other end being connected to the chord.

[0010] In another embodiment, the formwork structure further includes end connectors and bottom support connectors; the end connectors are disposed on the end plates of the inclined beam and the inclined brace; the bottom support connectors are disposed on the main rib, chord, and bottom rod; the end connectors at both ends of the inclined beam are respectively connected to the bottom support connectors on the main rib and the bottom rod, or respectively connected to the bottom support connectors on the main rib and the chord; the end connectors at both ends of the inclined brace cooperate with the bottom support connectors on the chord and the bottom rod.

[0011] In another embodiment, the secondary ribs are arranged at equal intervals from the bottom to the top of the carbon fiber template. The lower bottom side of the secondary ribs located at the bottom and top is connected to carbon fiber, while the upper bottom side of the remaining secondary ribs located in the middle is connected to carbon fiber.

[0012] Beneficial effects: The single-sided formwork structure, composed of double C-shaped beam units and E-shaped beams made of carbon fiber formwork and high-strength steel, reduces weight by more than 30% and increases bending strength by 15-20% compared to traditional steel formwork. Furthermore, in the single-sided formwork structure, the main beams, trusses, diagonal braces, and base members all utilize modularly designed double C-shaped beam units. These units can be freely combined on-site according to actual needs to achieve the required length dimensions for the main beams, trusses, diagonal braces, and base members, making construction more flexible. Modular openings on the double C-shaped beam units facilitate adjustment of the connection between longitudinal beams, diagonal beams, and main beams / chords at any height, as well as the connection between diagonal braces and chords / base members at any position. Modular openings on the E-shaped beams facilitate reinforcement of the connection between the main beams and secondary beams at any position. Attached Figure Description
