[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0025] like Figures 1-4 As shown, a wall surface plaster-free construction template of this embodiment includes two sets of raised stamping steel plates 1 and a formwork support assembly. The two sets of raised stamping steel plates 1 are arranged in parallel and opposite to each other, and the two sets of raised stamping steel plates 1 are tightened and fixed by the formwork support assembly. Each set of raised stamping steel plates 1 has multiple stamping protrusions 11 on one side surface, and the stamping protrusions 11 of the two sets of raised stamping steel plates 1 are arranged opposite to each other.

[0026] The height of the stamped protrusion 11 is 3-5mm, and the diameter is 20mm. The protrusion is set on the stamping steel plate 1, which makes the template surface easy to clean during use. The protrusion is on the inside of the template and is in direct contact with the concrete. After the template is removed, the concrete surface is a uniform concave surface.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, the stamping protrusion 11 is a hemispherical structure.

[0028] like Figure 1 As shown in this embodiment, multiple stamping protrusions 11 are evenly arranged on one side surface of each group of protrusion stamping steel plate 1.

[0029] like Figure 2 As shown, each set of convex stamping steel plates 1 in this embodiment includes at least two convex stamping steel plates 1, and adjacent two convex stamping steel plates 1 are connected and fixed by connectors 2.

[0030] like Figure 2 As shown, in this embodiment, the vertical edge of the convex stamped steel plate 1 is provided with an outwardly protruding connecting strip 12, and the connecting strips 12 of two adjacent convex stamped steel plates 1 are connected and fixed by a connector 2. By setting the connecting strip, it is convenient to connect and fix two adjacent convex stamped steel plates.

[0031] like Figure 2 As shown, optionally, the connector 2 is a bolt assembly or a pin assembly.

[0032] like Figures 2-4As shown, the formwork assembly in this embodiment includes an aluminum alloy frame 3 and back ribs 31. Each set of protruding stamped steel plates 1 has an aluminum alloy frame 3 on its other side surface. The outer side of each aluminum alloy frame 3 has horizontally arranged back ribs 31. The back ribs 31 of the two sets of aluminum alloy frames 3 are arranged one-to-one in the horizontal direction, and the corresponding set of back ribs 31 is tightened and fixed by a tensioning assembly. By setting the aluminum alloy frame and back ribs, the tensioning and fixing between the two protruding stamped steel plates is facilitated. The back ribs are square steel back ribs, which can prevent deformation at the corners and other parts of the formwork during assembly, and ensure the overall squareness and flatness of the wall.

[0033] like Figure 4 As shown, the tensioning assembly in this embodiment includes a pull tab 4 and a clamp 41. The pull tab 4 is arranged through two sets of protruding stamped steel plates 1 and two sets of aluminum alloy frames 3. The two ends of the pull tab 4 are respectively engaged and fixed to the corresponding back ribs 31 by the clamp 41. By adopting the pull tab reinforcement system, it is possible to avoid drilling holes in the template and leaving no holes on the wall surface after demolding, which greatly reduces the risk of external wall leakage and the cost of internal wall sealing. This saves on wall hole sealing materials and reduces labor costs.

[0034] Specifically, the pull tab 4 is a stainless steel pull tab.

[0035] like Figure 3 and Figure 4 As shown, in this embodiment, there is also a binding steel bar 5 between the two sets of protruding stamped steel plates 1.

[0036] The aluminum alloy frame in this embodiment has a thickness of 6mm and a weight of 7kg / m. 2 The high-strength aluminum alloy is cut and assembled into a frame through welding and riveting, and then custom-made 2.5mm stamped steel plates are used. Construction using a high-strength aluminum alloy frame has lower requirements for seasonal construction, high tensile strength and yield strength, and excellent performance in resisting loads and lateral stresses. It can prevent deformation under different forces during construction, effectively ensuring the verticality, flatness, and cross-sectional dimensions of the wall.

[0037] The aluminum alloy frame is assembled and fabricated to form a standard frame that is 400mm wide and 2500mm long. In order to avoid porosity, slag inclusion, undercut, incomplete penetration, cracks and other issues during the welding process, the oxide layer on the surface of the base material, temperature and humidity, and welding materials are strictly controlled from the source before welding. The stamped steel plate 1 with protrusions with a height of 3-5mm, a diameter of 10mm and a spacing of 20mm is assembled and welded to the aluminum alloy frame. After welding, the weld points are ground and rust-proofed, and then placed on the concrete ground 6. Repeat the above steps to produce a sufficient number of templates according to the detailed design drawings for aluminum formwork. The templates should be numbered, categorized, and stacked according to the unit type requirements. After the on-site wall and column reinforcement binding is completed, and the water, electricity, and ventilation pre-installations are completed and approved by the construction and supervision units, install the templates. First, assemble one side of the wall templates, placing steel tie rods at the template joints. The bottom tie rod should be at least 200mm from the ground, with a rectangular arrangement of ≤450mm spacing. The pin and pin placement should correspond to the tie rod positions. Assemble and fix multiple template pieces. After assembling one side of the templates, assemble the other side of the templates following the same steps. Arrange on the outside of the templates... The square steel back ribs are reinforced and leveled; in accordance with the requirements of GB50204-2015 Code for Acceptance of Construction Quality of Concrete Structures, test blocks cured under the same conditions are retained; after the concrete is poured, the wall side formwork is removed when the strength of the test blocks cured under the same conditions reaches more than 50% of the design strength, and the floating dust on the formwork surface is cleaned in time, and a water-based release agent is applied and left for the next layer for later use; before using this device, the surface is coated with a water-based release agent. The purpose of the release agent is to facilitate demolding after the concrete is poured, to avoid the formwork and concrete contact parts from sticking to the structural surface and affecting the appearance quality, and at the same time to facilitate the cleaning and maintenance of the formwork surface, and to enhance the turnover rate of the formwork.

[0038] This embodiment uses a high-strength aluminum alloy frame assembled with custom-made stamped steel panels. High-strength aluminum alloy was chosen because of its excellent corrosion resistance, durability, lightweight nature, and ease of processing, reducing construction costs and environmental impact. The use of standardized stamping dies for the steel panels effectively ensures the correct height, density, and spacing of the raised points.

[0039] The wall surface formwork without grouting described in this embodiment is applicable to walls, beams, and other structures, offering strong versatility and flexibility. It eliminates the need for roughening and grouting, is easy to transport, and boasts excellent dismantling performance and high practicality, providing convenience and effective protection for concrete construction. Furthermore, the wall surface formwork can be reused multiple times, achieving material conservation and cost savings, resulting in high economic benefits.
