Description

Technical Field

[0001] The present invention relates to the technical field of template engineering, and in particular to a visual three-dimensional fiber grid disassembly-free template. Background Art

[0002] Concrete formwork is a temporary structure used to support and shape concrete in construction projects. It ensures that concrete components are formed according to the designed shape and dimensions and withstands the loads during the pouring process. Existing concrete formwork typically uses wooden, steel, aluminum, or plastic molds to enclose the cast-in-place concrete cavity. After the concrete solidifies and takes shape, the formwork needs to be removed.

[0003] However, existing concrete formwork has problems such as long construction period, turnover restrictions, and low control over concrete forming structure and quality, resulting in low overall reliability.

[0004] Therefore, how to effectively improve the reliability of concrete formwork, shorten the construction period, and improve the concrete forming structure and quality has become an urgent problem to be solved in this field. Summary of the Invention

[0005] In view of the defects of the prior art, the purpose of the present invention is to provide a visual three-dimensional fiber grid non-disassembly formwork that is stable, reliable, effective, shortens the construction period, and improves the concrete forming structure and quality.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a visual three-dimensional fiber grid non-disassembly template, comprising:

[0007] The concrete pouring frame is composed of a number of steel bars connected together to form a cubic grid frame suitable for the concrete design structure. The main load-bearing bars are distributed in the concrete pouring frame.

[0008] A three-dimensional fiber grid anti-leakage slurry layer is arranged on the outside of the concrete pouring frame, and is composed of an outer fiber grid, a fiber core column assembly and an inner fiber grid connected and coordinated. The two ends of the fiber core column assembly are respectively connected to and support the outer fiber grid and the inner fiber grid, and the inner fiber grid is connected to the concrete pouring frame.

[0009] Furthermore, the main load-bearing reinforcement includes longitudinal reinforcement steel bars and transverse reinforcement steel bars that are arranged in a staggered manner.

[0010] Furthermore, the fiber core column assembly includes a plurality of fiber core column groups distributed at intervals, each fiber core column group includes a plurality of fiber core columns distributed in parallel, and two adjacent fiber core columns are distributed in anti-phase symmetrical wave shapes.

[0011] Furthermore, the outer fiber grid and the inner fiber grid are respectively formed by interweaving warp fiber yarns and weft fiber yarns.

[0012] Furthermore, the fiber core, warp fiber yarns and weft fiber yarns are respectively composed of basalt fibers.

[0013] Furthermore, the pore size of the outer fiber mesh is smaller than the pore size of the inner fiber mesh.

[0014] Furthermore, the pore size of the outer fiber mesh is ≤3 mm, and the pore size of the inner fiber mesh is ≤5 mm.

[0015] Furthermore, the inner fiber grid is fixed to the outside of the concrete pouring frame by means of tying wires.

[0016] The present invention provides a visualized three-dimensional fiber grid disassembly-free formwork, and the concrete pouring frame is composed of a plurality of steel bars connected to form a cubic grid frame, and main load-bearing bars are distributed in the concrete pouring frame. When concrete is poured in the concrete pouring frame, the forming structure and quality of the concrete can be strengthened by the main load-bearing bars. At the same time, a three-dimensional fiber grid anti-leakage slurry layer is provided on the outside of the concrete pouring frame. The three-dimensional fiber grid anti-leakage slurry layer forms two layers of anti-leakage grids, which can effectively ensure that the concrete slurry does not leak out, thereby improving the mechanical strength of the wall concrete.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0028] See also Figure 1 , which shows an example of the visual three-dimensional fiber grid non-disassembly template provided by the present invention.

[0029] As can be seen from the figure, the visual three-dimensional fiber grid non-removal formwork of this example mainly includes a concrete pouring frame 1 and a three-dimensional fiber grid anti-leakage slurry layer 2.

[0030] The concrete casting frame 1 is composed of a number of steel bars connected and matched to form a cubic grid frame suitable for the concrete design structure. The concrete casting frame 1 is distributed with load-bearing main bars 11 to strengthen the structure and quality of the cast-in-place concrete. The three-dimensional fiber grid anti-leakage slurry layer 2 is arranged on the outside of the concrete casting frame 1, and is composed of an outer fiber grid 21, a fiber core column assembly 22 and an inner fiber grid 23. The two ends of the fiber core column assembly 23 are respectively connected to and support the outer fiber grid 21 and the inner fiber grid 22. The inner fiber grid 23 is connected to the concrete casting frame 1 to effectively prevent the concrete slurry from leaking. The concrete casting frame 1 and the three-dimensional fiber grid anti-leakage slurry layer 2 do not need to be dismantled, shortening the construction period.

[0031] Combine Figure 1 and Figure 2 The concrete pouring frame 1 is preferably composed of a plurality of crude steels with a diameter ≥5 mm connected to each other to form a cubic grid frame, and the structural shape and size of the cubic grid frame are adapted to the concrete design structure. In some embodiments, a pouring port 12 is formed at the top of the concrete pouring frame 1, and concrete is poured from the pouring port 12 or the gap between the top steel bars, so that the concrete can solidify and take shape in the concrete pouring frame 1 to meet the concrete design structure.

[0032] At the same time, the several steel bars of the concrete casting frame 1 can not only serve as components of the concrete casting frame 1, but also cooperate with the cast-in-place concrete to form the skeleton of the concrete forming structure, which can stabilize the forming structure and quality of the concrete. After the concrete is solidified and formed, there is no need to dismantle the concrete casting frame 1, so as to shorten the construction period.

[0033] Combine Figure 1 and Figure 2 Furthermore, main load-bearing bars 11 are distributed in the concrete pouring frame 1 so that the main load-bearing bars 11 can cooperate with the cast-in-place concrete to enhance the stability and mechanical properties of the concrete forming structure.

[0034] As an example, the main load-bearing reinforcement 11 includes longitudinal reinforcement steel bars 111 and transverse reinforcement steel bars 112 that are arranged in an alternating manner, so that the longitudinal reinforcement steel bars 111 and transverse reinforcement steel bars 112 can respectively reinforce the longitudinal distribution structure and transverse distribution structure of the concrete forming structure to ensure the stability of the concrete forming structure.

[0035] Preferably, the longitudinal reinforcement steel bars 111 and the transverse reinforcement steel bars 112 are composed of steel bars with a diameter of ≥5 mm and are welded or tied to each other to ensure that the longitudinal reinforcement steel bars 111 and the transverse reinforcement steel bars 112 can stably cooperate to reinforce the concrete forming structure.

[0036] Combine Figure 3 In order to prevent the concrete slurry in the concrete pouring frame 1 from leaking out and affecting the concrete forming structure, a three-dimensional fiber grid anti-leakage slurry layer 2 is provided on the outside of the concrete pouring frame 1. The three-dimensional fiber grid anti-leakage slurry layer 2 is composed of an outer fiber grid 21, a fiber core column assembly 22 and an inner fiber grid 23 connected and matched. Two layers of anti-leakage grids are formed on the outside of the concrete pouring frame 1, which can effectively prevent the concrete slurry from leaking out.

[0037] Combine Figure 3 and Figure 4 Specifically, the fiber core column assembly 22 includes several groups of spaced-apart fiber core column groups 221. The several fiber core column groups 221 can be distributed between the outer fiber grid 21 and the inner fiber grid 23, and cooperate with each other to connect and support the outer fiber grid 21 and the inner fiber grid 23, ensuring the connection and cooperation stability of the fiber grid 21 and the inner fiber grid 23, and at the same time making the outer fiber grid 21 and the inner fiber grid 23 cooperate to form two layers of leak-proof grids.

[0038] Combine Figure 3 and Figure 4 Furthermore, each group of fiber core columns 221 includes a number of fiber core columns 2211 distributed in parallel, and the two adjacent fiber core columns 2211 are distributed in an anti-symmetrical wave shape, so that when the concrete poured in the concrete pouring frame 1 generates lateral pressure on the three-dimensional fiber grid anti-leakage slurry layer 2, the wavy fiber core columns 2211 will be elastically compressed, generating a radial expansion force on the outer fiber grid 21 and the inner fiber grid 23, pushing the outer fiber grid 21 and the inner fiber grid 23 to move away from each other, so that the inner fiber grid 23 is close to the gap of the concrete pouring frame, ensuring that the concrete slurry will not leak out.

[0039] At the same time, the wavy distribution of the two adjacent fiber core columns 2211 is anti-symmetrical, so that the two adjacent fiber core columns 2211 can cooperate with each other to provide a stable radial expansion force for the outer fiber grid 21 and the inner fiber grid 23, and can cope with lateral pressure in all directions to ensure that the three-dimensional fiber grid anti-leakage slurry layer 2 has uniform force performance.

[0040] Furthermore, when concrete vibration is performed in the concrete pouring frame 1 , the elastic deformation of two adjacent fiber core columns 2211 can stably absorb pressure pulses and reduce the risk of instantaneous concrete leakage.

[0041] Combine Figure 3 and Figure 5 In coordination with this, the outer fiber grid 21 and the inner fiber grid 23 are respectively composed of warp fiber yarns 211 and weft fiber yarns 212 interwoven together, so that the warp fiber yarns 211 and weft fiber yarns 212 are coordinated and distributed to form a fine grid-like distribution of the outer fiber grid 21 and the inner fiber grid 23, thereby preventing the concrete slurry from leaking.

[0042] Preferably, the fiber core column 2211, the warp fiber yarn 211 and the weft fiber yarn 212 are respectively composed of basalt fibers. The interfacial bonding force between the basalt fibers and the concrete enables the basalt fibers to bear part of the tensile stress during the tensile process, thereby significantly improving the tensile strength and shear strength of the concrete formed structure.

[0043] As an example, the fiber core 2211, the warp fiber yarn 211 and the weft fiber yarn 212 may also be composed of glass fiber, polyester fiber, nylon fiber, etc. according to specific application conditions.

[0044] Furthermore, the inner fiber grid 22 is preferably fixed to the outside of the concrete casting frame 1 by tying wire to improve construction efficiency. At the same time, the pore size of the inner fiber grid 22 is larger than the pore size of the outer fiber grid 21, thereby forming two layers of leak-proof grids with a dense outer layer and a sparse inner layer on the outside of the inner fiber grid 22 of the concrete casting frame 1, which can enable the outer fiber grid 21 and the concrete slurry to be effectively leak-proof and construction reliability to be achieved in a coordinated manner.

[0045] For example, the pore size of the inner fiber mesh 22 is ≤5mm, which can block coarse aggregate and prevent the coarse aggregate from directly impacting the outer fiber mesh 21 and causing damage. The pore size of the outer fiber mesh 21 is ≤3mm, which can block fine cement particles and completely block the leakage path of the concrete slurry.

[0046] At the same time, the inner fiber mesh 22 with a larger pore size can allow the slurry to quickly flow back into the concrete pouring frame 1 during the concrete vibration operation, filling the concrete voids, eliminating the air bag effect of the traditional single-layer dense mesh, preventing local leakage caused by the concrete air bag effect, and improving the density of the concrete forming structure.

[0047] The three-dimensional fiber grid anti-leakage slurry layer 2 thus formed is composed of the outer fiber grid 21, the fiber core column assembly 22 and the inner fiber grid 23, forming two layers of anti-leakage grids on the outside of the concrete pouring frame 1, which can effectively prevent the concrete slurry from leaking and improve the stability and quality of the concrete forming structure.

[0048] Furthermore, the three-dimensional fiber grid anti-leakage slurry layer 2 and the concrete pouring frame 1 both serve as the skeleton structure of the concrete forming structure and do not need to be dismantled, which can effectively shorten the construction period.

[0049] At the same time, the three-dimensional fiber grid anti-leakage slurry layer 2 and the concrete pouring frame 1 can intuitively visualize the concrete pouring situation and density inside the concrete pouring frame 1, thereby efficiently controlling the concrete pouring operation and ensuring the stability and quality of the concrete forming structure.

[0050] The visual three-dimensional fiber grid non-removable formwork, the concrete pouring frame 1 and the three-dimensional fiber grid anti-leakage slurry layer 2 thus formed can effectively strengthen the forming structure and quality of the concrete through the load-bearing main reinforcement 11, and form two layers of anti-leakage grids to effectively ensure that the concrete slurry does not leak out, thereby improving the mechanical strength of the wall concrete. There is no need to dismantle the concrete pouring frame and the three-dimensional fiber grid anti-leakage slurry layer, which can effectively shorten the construction period.
