Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy template technology, specifically a double-layer aluminum alloy template. Background Technology

[0002] In the field of modern construction, especially in high-rise buildings and standardized construction, aluminum alloy formwork has gradually replaced traditional wooden and steel formwork and become the mainstream construction tool for main concrete pouring due to its advantages such as lightweight and high strength, high turnover rate, high construction efficiency and good forming quality.

[0003] The existing patent (authorization announcement number: CN222667588U) discloses a double-layer aluminum alloy formwork. The key technical points of the solution are: by using aluminum plates in combination with a reinforcing frame, the compressive strength of the formwork body is improved, the structural stability of the formwork body is enhanced, and the maximum load-bearing capacity is increased. At the same time, by using crossbars and diagonal braces in combination, the crossbars improve the support stability of the inner wall of the formwork body, thereby increasing the resistance to deformation and making it easier for workers to handle and use during installation. Meanwhile, the hollow crossbars are lighter, and the diagonal braces strengthen the connection between the crossbars and the aluminum plates, guide the force, and distribute the pressure.

[0004] However, the above technical solutions still have certain drawbacks. Single-layer metal structures have fast heat conduction, which is not conducive to building energy conservation. They cannot reduce heat loss during winter construction and cannot improve the construction environment and the sound insulation effect of the future building. Therefore, a double-layer aluminum alloy formwork is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a double-layer aluminum alloy template to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A double-layer aluminum alloy template includes an installation plate and closing plates installed on both sides of the installation plate. The closing plates are provided with locking components to help the two sets of templates engage. The inner wall of the installation plate is provided with reinforcing members to improve the strength of the template, and a locking component is provided between the two sets of closing plates.

[0008] The reinforcing member is disposed inside the mounting plate, between the two sets of closed plates, and the outer edge of the reinforcing member is connected to the inner surface of the mounting plate; the two closed plates respectively cover the upper and lower large surfaces of the mounting plate, so that the mounting plate and the closed plates together form a closed hollow cavity, and bolt holes are provided on both sides of the mounting plate for easy connection.

[0009] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0010] As a further embodiment of this utility model: the reinforcing member is a honeycomb core material, and the reinforcing member is made of aluminum alloy material.

[0011] As a further embodiment of this utility model: the locking assembly includes an internally threaded sleeve embedded in one of the closed plates and a locking bolt penetrating the other closed plate, wherein the locking bolt is threadedly connected to the internally threaded sleeve.

[0012] As a further improvement of this utility model, the two closed plates are provided with corresponding tie rod holes for threading tie rods.

[0013] As a further embodiment of this utility model: the engaging assembly includes an engaging groove formed on the top of the closing plate, a locking block slidably disposed in the engaging groove, a sliding block fixedly installed on the side of the locking block, a sliding groove formed on the side of the closing plate to facilitate the sliding of the sliding block, and a spring connected to the locking block is provided in the engaging groove.

[0014] As a further improvement of this utility model, the bottom of the closing plate is provided with a locking head that is easy to insert into the locking groove.

[0015] As a further improvement of this utility model: the locking assembly is provided in four sets, and the locking bolts and internal threaded sleeves of the four sets of locking assemblies are respectively provided to correspond to the honeycomb-shaped holes penetrating the honeycomb core material.

[0016] As a further improvement of this utility model, the mounting plate is formed by stamping rust-proof aluminum alloy sheet.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. By setting up honeycomb-shaped reinforcing members, the closed honeycomb pores are filled with air. Air is a good thermal insulator and sound insulator, which makes the template perform better than solid templates in terms of thermal insulation and sound insulation. It can improve the construction environment to a certain extent and has a positive effect on the curing of concrete. In addition, the honeycomb structure gives the template high compressive, bending and shear strength.

[0019] 2. This utility model uses a locking component, through the cooperation of locking bolts and internal threaded sleeves, to balance the huge lateral pressure of concrete on the formwork during pouring, preventing the formwork from expanding outward. Multiple locking components work together to evenly distribute the clamping force between the two formwork pieces across the entire contact surface, avoiding problems such as poor sealing and deformation caused by excessive local stress or uneven connection.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figures 1-5 As shown, a double-layer aluminum alloy template includes an installation plate 1 and closing plates 2 installed on both sides of the installation plate 1. The closing plates 2 are provided with locking components 3 to help the two sets of templates lock together. The inner wall of the installation plate 1 is provided with reinforcing members 5 to improve the strength of the template, and a locking component 6 is provided between the two sets of closing plates 2.

[0030] In this embodiment, the inner surfaces of the mounting plate 1 and the closing plate 2 are supported by the reinforcing member 5 to prevent them from denting or bulging inward under great pressure. At the same time, the locking component 3 enables rapid pre-positioning in the vertical direction, improving installation efficiency. After the two templates are initially positioned by the locking component 3, the locking component 6 is used to tightly connect the closing plates 2 of the two templates together, forming a sealed space inside the mounting plate 1.

[0031] In one embodiment, such as Figure 4As shown, the reinforcing member 5 is disposed inside the mounting plate 1, between the two sets of closed plates 2, and the outer edge of the reinforcing member 5 is connected to the inner surface of the mounting plate 1. The two closed plates 2 respectively cover the upper and lower large surfaces of the mounting plate 1, so that the mounting plate 1 and the closed plates 2 together form a closed hollow cavity. Bolt holes for easy connection are opened on both sides of the mounting plate 1, and the mounting plate 1 is stamped from rust-proof aluminum alloy sheet. When the template surface is subjected to concrete pressure, the force is transmitted to the mounting plate 1 through the closed plates 2, and then efficiently transmitted to the internal reinforcing member 5 through the connection points. The reinforcing member 5 provides numerous support points for the core skeleton, effectively preventing local buckling of the mounting plate 1 and the closed plates 2 under pressure. The strong material is distributed in the outermost and middle positions farthest from the neutral axis, thus achieving extremely high overall stiffness and strength with relatively thin material. While providing high strength, the hollow structure is significantly lighter than solid steel templates or thick aluminum plates that achieve the same performance. This makes the operation easier for workers, the installation and disassembly efficiency higher, and reduces labor intensity and safety risks.

[0032] In one embodiment, such as Figure 4 As shown, the reinforcing member 5 is a honeycomb core material made of aluminum alloy. By arranging the reinforcing member 5 in a honeycomb structure, the honeycomb structure maximizes material utilization efficiency, giving the formwork high compressive, bending, and shear strength with minimal weight increase. This makes the formwork extremely robust yet very lightweight, simplifying handling and installation, and increasing construction efficiency. Furthermore, the closed honeycomb pores are filled with air, which is an excellent thermal and acoustic insulator. This makes the formwork superior to solid formwork in terms of thermal insulation and sound insulation, improving the construction environment to some extent and having a positive effect on concrete curing.

[0033] In one embodiment, such as Figure 5As shown, the locking assembly 6 includes an internally threaded sleeve 61 pre-embedded in one of the closed plates 2 and a locking bolt 62 penetrating the other closed plate 2. The locking bolt 62 is threadedly connected to the internally threaded sleeve 61. The two closed plates 2 are respectively provided with tie rod holes for passing through the tie rods. The locking assembly 6 is provided in four sets, and the locking bolts 62 and internally threaded sleeves 61 of the four sets of locking assemblies 6 are respectively provided with honeycomb-shaped holes penetrating the honeycomb core material. After the two templates are initially aligned by the locking assembly 3, the worker tightens the locking bolts 62 with tools. The screwing in of the bolts generates a strong clamping force, tightly pulling the closed plates 2 of the two templates together, thus achieving a robust and rigid connection between the two templates. The tie rod bears the tension through its body, and this tension, in turn, generates a huge reverse compressive force on the two templates, thereby balancing the huge lateral pressure of the concrete on the templates during pouring and preventing the templates from expanding outward. Multiple locking components 6 work together to evenly distribute the clamping force between the two templates across the entire contact surface, avoiding problems such as poor sealing and deformation caused by excessive local stress or uneven connection.

[0034] In one embodiment, such as Figure 3 As shown, the engaging assembly 3 includes an engaging groove 31 formed on the top of the closing plate 2. A locking block 32 is slidably disposed in the engaging groove 31. A sliding block 33 is fixedly installed on the side of the locking block 32. A sliding groove is formed on the side of the closing plate 2 to facilitate the sliding of the sliding block 33. A spring 34 is provided in the engaging groove 31 to connect the closing plate 2 and the locking block 32. An engaging head 4 is provided at the bottom of the closing plate 2 to facilitate insertion into the engaging groove 31. The upper closing plate 2 and the lower closing plate 34 are connected by a locking groove 31. The closing plates 2 are aligned, allowing the engaging head 4 to insert into the engaging groove 31. The locking block 32 compresses the spring 34, causing the engaging head 4 to retract into the engaging groove 31. The groove at the bottom of the locking block 32 hooks the engaging head 4, preventing it from detaching. To detach, manually pull the sliding block 33 to lift the closing plates 2, thus separating the two sets of closing plates 2. This allows workers to install the upper template without precise alignment; they only need to roughly align the bottom engaging head 4 with the opening of the lower engaging groove 31 and lower it by its own weight. Guided by the inclined surface, the assembly automatically completes the correction and locking process.

[0035] The above embodiment discloses a double-layer aluminum alloy formwork. By roughly aligning the bottom locking head 4 with the locking groove 31 on the top of the lower, already installed formwork, the upper formwork falls, and the locking head 4 inserts into the locking groove 31. Utilizing its inclined design, even minor deviations can be automatically guided and corrected, achieving precise alignment. Workers use bolts to pass through the bolt holes on the sides of adjacent formwork mounting plates 1, connecting multiple formwork pieces horizontally to form a larger, continuous construction surface. Workers use tools to tighten the locking bolts 62 of the locking assembly 6. The bolts are screwed into the internally threaded sleeves 61 embedded in the adjacent formwork, generating a strong clamping force that tightly pulls the closing plates 2 of the two formwork pieces together. After all the formwork is assembled and secured, concrete is poured into the formwork system.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
