Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to a pre-embedded device and aluminum formwork structure for aluminum formwork construction. Background Technology

[0002] In modern construction, high-rise residential buildings mostly employ a combination of prefabricated technology and aluminum formwork support systems. Compared to traditional wooden formwork, aluminum alloy formwork systems demonstrate significant advantages during construction: Firstly, their installation and dismantling speeds are significantly faster, helping to shorten the overall project cycle; secondly, due to the high flatness and rigidity of the aluminum formwork material, the forming quality and appearance of the wall structure after concrete pouring are superior.

[0003] However, aluminum formwork also has certain limitations. Especially when facing narrow or complex interior spaces, aluminum formwork systems are difficult to reinforce, install, and dismantle, and are not easily adjusted to adapt to the requirements of special structural parts. To solve this problem, common construction strategies include pre-embedding foam boards or wooden boxes to assist in formwork installation, or combining wooden and aluminum alloy formwork for mixed support. However, pre-embedded components in narrow or complex spaces are not easy to remove, often requiring later chiseling and repair, increasing the input of manpower and materials, and raising project costs. Summary of the Invention

[0004] The technical problem that this invention aims to solve is that embedded parts located in narrow or complex spaces are not easy to remove, often requiring subsequent chiseling and repair, which increases the input of manpower and material resources and raises the cost of the project.

[0005] To solve the above-mentioned technical problems, the present invention provides a pre-embedded device for aluminum formwork construction, including a concealed handle, a first connecting component, an elastic platform component, and a pre-embedded housing. The pre-embedded housing includes a connecting plate and multiple side plates. The connecting plate and the multiple side plates enclose a receiving cavity. The connecting plate is connected to the aluminum formwork, and the connecting plate has an installation port communicating with the receiving cavity. The first connecting component and the elastic platform component are located inside the receiving cavity.

[0006] The first connecting assembly includes a force-bearing component group, a connecting component, and a force-applying group. The force-bearing component group is fixed to the side of the connecting plate facing the receiving cavity. The connecting component is rotatably connected to the force-bearing component group. The concealed handle is located at the mounting port and connected to the connecting component. The force-applying group is connected to the connecting component, and one side of the force-applying group abuts against the concealed handle. The other side of the force-applying group abuts against the elastic platform assembly. The side of the elastic platform assembly opposite to the force-applying group is fixed inside the receiving cavity.

[0007] When the concealed handle is not pressed, the side of the concealed handle away from the force-bearing component assembly is flush with the side of the connecting plate away from the receiving cavity; when disassembly is required, press the concealed handle and rotate the force-bearing assembly to one side, so that the other side of the concealed handle is raised to provide a gripping part to remove the entire device from the concrete.

[0008] In some embodiments, the force-bearing component assembly includes a first mounting base, a second mounting base, and a rotating shaft. The first mounting base and the second mounting base are fixed to the side of the connecting plate facing the receiving cavity, and the first mounting base and the second mounting base are disposed opposite to each other on both sides of the connecting member. The rotating shaft passes through the first mounting base, the connecting member, and the second mounting base in sequence, so that the connecting member can rotate through the rotating shaft.

[0009] In some embodiments, the force application assembly includes a first fixed rod, a second fixed rod, a first pulley, and a second pulley. The first pulley is connected to one side of the connecting member via the first fixed rod, and the second pulley is connected to the other side of the connecting member via the second fixed rod. The two sides of the first pulley abut against the concealed handle and the elastic platform assembly, respectively, and the two sides of the second pulley abut against the concealed handle and the elastic platform assembly, respectively.

[0010] In some embodiments, the first connecting component further includes a first limiting component, which clamps both sides of the elastic platform component along a first direction and is sleeved around the pivot.

[0011] In some embodiments, the first limiting component includes two opposing first limiters, which are disposed opposite to each other on both sides of the elastic platform component. Each first limiter includes a sleeve sleeved around the circumference of the rotating shaft and a clamping plate connected to the sleeve. The clamping plate abuts against the corresponding side of the elastic platform component.

[0012] In some embodiments, the elastic platform assembly includes a first force-bearing platform, a second force-bearing platform, and a telescopic spring. One side of the first force-bearing platform abuts against the force-applying assembly, and one side of the second force-bearing platform is fixed within the receiving cavity. The first force-bearing platform and the second force-bearing platform are connected by the telescopic spring.

[0013] In some embodiments, a second limiting component is further included, which clamps the elastic platform component on both sides along a second direction.

[0014] In some embodiments, a second connecting component is further included, wherein the side of the elastic platform component opposite to the force application group is connected to the second connecting component, and one end of the second connecting component opposite to the elastic platform component is fixed to the side plate disposed opposite to the connecting plate.

[0015] In some embodiments, the second connecting assembly includes a connecting pipe, a base plate, and a fixing nut. One end of the connecting pipe is fixed to the elastic platform assembly, and the other end of the connecting pipe is fixed to the base plate. The base plate is fixed to the side plate disposed opposite to the connecting plate by the fixing nut.

[0016] The present invention also provides an aluminum formwork structure, including an aluminum formwork, concrete, and an embedded device as described above. The embedded device is detachably installed on the aluminum formwork by means of fasteners. The concrete fills the filling space formed by the aluminum formwork and the embedded device, and the embedded device is coated with a release agent.

[0017] Compared with the prior art, the embedded device for aluminum formwork construction according to an embodiment of the present invention has the following advantages:

[0018] When not in use, the concealed handle of this embodiment is flush with the connecting plate to ensure that the flatness and integrity of the concrete pouring are not affected after pre-embedding. When removal is required, the operator can press the concealed handle, causing it to rotate through the connecting component and the force application group. The elastic platform component deforms and displaces under the pressure changes of the force application group, causing the other side of the concealed handle to lift up and become an easy gripping position, thus easily pulling the entire pre-embedded device out of the hardened concrete structure. When the pressing pressure on the concealed handle is removed, the concealed handle returns to its flush position with the connecting plate. The elastic platform component and the second connecting component cooperate to form a support structure, which supports the concealed handle and provides support force to return it to its original position. This makes the pre-embedded device easy to install and remove, and simple to operate, reducing the process and subsequent maintenance, lowering the input of manpower and material resources, and reducing costs.

[0026] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0027] like Figures 1 to 4 As shown, the present invention provides an aluminum mold structure, including an aluminum mold 1, concrete and an embedded device 2. The embedded device 2 is detachably installed on the aluminum mold 1 by means of fasteners. The concrete fills the filling space formed by the aluminum mold 1 and the embedded device 2, and the embedded device 2 is coated with a release agent.

[0028] Understandably, during installation, the embedded device 2 is fixed to the aluminum formwork 1 using fasteners, and concrete is poured. After the concrete has solidified, the aluminum formwork 1 is removed, and the embedded device 2 is removed from the concrete. If any obstruction occurs, the junction between the device and the concrete can be gently tapped with a tool. The release agent must be evenly applied to the outside of the embedded device 2 before pouring; the same release agent can be used as the aluminum formwork 1.

[0029] See also Figure 5The embedded device 2 used for the construction of aluminum formwork 1 is mainly used for pre-installation in narrow or complex spaces before pouring concrete, and can be easily removed from the concrete structure when needed later. Specifically, the embedded device 2 includes a hidden handle 21, a first connecting component 22, an elastic platform component 23, and an embedded housing 24. The embedded housing 24 includes a connecting plate 241 and multiple side plates 242. The connecting plate 241 and the multiple side plates 242 enclose a receiving cavity 243. The connecting plate 241 is connected to the aluminum formwork 1, and the connecting plate 241 has an installation port that communicates with the receiving cavity 243. The first connecting component 22 and the elastic platform component 23 are located inside the receiving cavity 243.

[0030] The first connecting assembly 22 includes a force-bearing component group 221, a connecting component 222, and a force-applying assembly 223. The force-bearing component group 221 is fixed to the side of the connecting plate 241 facing the receiving cavity 243. The connecting component 222 is rotatably connected to the force-bearing component group 221. The concealed handle 21 is located at the mounting port and is connected to the connecting component 222. The force-applying assembly 223 is connected to the connecting component 222, and one side of the force-applying assembly 223 abuts against the concealed handle 21. The other side of the force-applying assembly 223 abuts against the elastic platform assembly 23. The side of the elastic platform assembly 23 away from the force-applying assembly 223 is fixed in the receiving cavity 243.

[0031] When the concealed handle 21 is not pressed, the side of the concealed handle 21 away from the force-bearing component assembly 221 is flush with the side of the connecting plate 241 away from the receiving cavity 243; when disassembly is required, the concealed handle 21 is pressed and the force-bearing assembly 223 is rotated to one side, so that the other side of the concealed handle 21 is raised to provide a gripping part to remove the entire device from the concrete.

[0032] Based on the above structure, when not in use, the concealed handle 21 of this embodiment can be flush with the connecting plate 241 to ensure that the flatness and integrity of the concrete pouring are not affected after pre-embedding. When removal is required, the operator can press the concealed handle 21, causing it to rotate through the connecting member 222 and the force application group 223. The elastic platform component 23 can deform and generate displacement when subjected to pressure changes from the force application group 223, thereby causing the other side of the concealed handle 21 to tilt up to a position that is easy to grip, thus easily pulling the entire pre-embedded device 2 out of the hardened concrete structure. Then, when the pressing pressure on the concealed handle 21 is removed, the concealed handle 21 returns to a state flush with the connecting plate 241, and one side of the elastic platform component 23 is fixed in the receiving cavity 243, which serves to support the concealed handle 21 and provide it with a supporting force to return to its original position, so that the pre-embedded device 2 is easy to install, easy to remove, and simple to operate, reducing the process and subsequent maintenance by personnel.

[0033] It should be noted that the connecting plate 241 and the side plate 242 are made of aluminum / steel plates, both using common materials with a thickness of at least 2mm. The aluminum / steel plates are cut according to actual conditions and connected by welding. In this embodiment, an installation port can be opened on each side plate 242 to communicate with the receiving cavity 243, and the corresponding structure described above can be installed to achieve the installation and use of the concealed handle 21 on different surfaces. The aforementioned aluminum / steel plates are common materials found on construction sites, and are characterized by reusability and easy processing.

[0034] In some embodiments, the force-bearing component assembly 221 includes a first mounting base 2211, a second mounting base, and a rotating shaft 2212. The first mounting base 2211 and the second mounting base are fixed to the side of the connecting plate 241 facing the receiving cavity 243, and the first mounting base 2211 and the second mounting base are disposed opposite to each other on both sides of the connecting member 222, so that the force-bearing component assembly 221 can effectively support the connecting member 222. The rotating shaft 2212 passes through the first mounting base 2211, the connecting member 222, and the second mounting base in sequence, so that the connecting member 222 can rotate through the rotating shaft 2212. In this embodiment, through the above structure, the connecting member 222 can rotate around the rotating shaft 2212, so that when disassembling, the connecting member 222 can be driven to rotate by pressing the hidden handle 21, and the other end of the hidden handle 21 is lifted under the support of the elastic platform assembly 23, so that the operator can hold it and complete the operation of pulling the entire embedded device 2 out of the concrete.

[0035] In some embodiments, the force application assembly 223 includes a first fixed rod 2231, a second fixed rod 2232, a first pulley 2233, and a second pulley 2234. The first pulley 2233 is connected to one side of the connecting member 222 via the first fixed rod 2231, and the second pulley 2234 is connected to the other side of the connecting member 222 via the second fixed rod 2232. The two sides of the first pulley 2233 abut against the concealed handle 21 and the elastic platform assembly 23, respectively, and the two sides of the second pulley 2234 abut against the concealed handle 21 and the elastic platform assembly 23, respectively.

[0036] In this embodiment, when the concealed handle 21 is pressed, the force can be directly applied to the first pulley 2233 through the first fixed rod 2231. Simultaneously, the first pulley 2233 contacts the concealed handle 21 and the elastic platform assembly 23 on both sides, allowing the pressure from the concealed handle 21 to be converted into pressure along the first pulley 2233 during rotation under force, thus transmitting this force to the elastic platform assembly 23. Similarly, the connection structure of the second pulley 2234 ensures that regardless of the direction from which pressure is applied to the concealed handle 21, the force can be evenly and effectively transmitted to the elastic platform assembly 23 through the two pulley systems, thereby triggering the rotation of the internal structure of the embedded device 2, facilitating disassembly.

[0037] In some embodiments, the first connecting component 22 further includes a first limiting component 224, which clamps both sides of the elastic platform component 23 along a first direction to restrict the movement of the elastic platform component 23 within a certain range. Furthermore, the first limiting component 224 is sleeved around the rotating shaft 2212, so that it not only constrains the position of the elastic platform component 23 but also rotates together with the rotating shaft 2212, ensuring that the elastic platform component 23 will not move excessively due to uncontrolled movement when force is applied and transmitted through the connecting component 222. It should be noted that in this embodiment, the first direction is parallel to the width direction of the elastic platform component 23.

[0038] In some embodiments, the first limiting component 224 includes two opposing first limiters 2241, which are disposed opposite to each other on both sides of the elastic platform component 23, ensuring that the first limiters 2241 effectively limit and support the elastic platform component 23 from both sides.

[0039] In this embodiment, the first limiter 2241 includes a sleeve fitted around the circumference of the rotating shaft 2212 and a clamping plate connected to the sleeve. The clamping plate abuts against the corresponding side of the elastic platform assembly 23. When the elastic platform assembly 23 is subjected to a force and may move, the clamping plate provides stable resistance through its contact surface with the elastic platform assembly 23, thereby limiting the excessive extension or displacement of the elastic platform assembly 23 along the first direction, ensuring the stability of the internal structure of the embedded device 2 and the precise control of its operation.

[0040] In some embodiments, the elastic platform assembly 23 includes a first force-bearing platform 231, a second force-bearing platform 232, and a telescopic spring 233. One side of the first force-bearing platform 231 abuts against the force-applying assembly 223 so that when pressure is applied through the concealed handle 21 and force is transmitted through the force-applying assembly 223, the force will first act on the first force-bearing platform 231. One side of the second force-bearing platform 232 is fixed in the receiving cavity 243 to provide support for the second force-bearing platform 232 and prevent the concealed handle 21 from falling into the receiving cavity 243 and being unable to lift up when the second force-bearing platform 232 moves. The first force-bearing platform 231 and the second force-bearing platform 232 are connected by the telescopic spring 233, which serves as a connection and buffer. When an external force is applied to the first force-bearing platform 231, the telescopic spring 233 can deform within the allowable range to absorb and disperse part of the impact force. At the same time, it can return to its original shape after the force is released, so that the entire pre-embedded device 2 has a certain elastic deformation capacity, ensuring that the device can maintain stability and have good adaptability when subjected to different loads.

[0041] In practical applications, the side of the elastic platform component 23 that is away from the force application group 223 (that is, the second force-bearing platform 232) can be fixed in the accommodating cavity 243 by directly connecting it to the side plate 242 that is directly opposite to the connecting plate 241 or directly connecting it to the side plates 242 located on both sides.

[0042] In addition, in some embodiments, the pre-embedded device further includes a second connecting component 25. The side of the elastic platform component 23 facing away from the force application group 223 is connected to the second connecting component 25, and the end of the second connecting component 25 facing away from the elastic platform component 23 is fixed to the side plate 242 which is opposite to the connecting plate 241. In this embodiment, the elastic platform component 23 and the second connecting component 25 cooperate to form a support structure, which plays the role of supporting the hidden handle and providing it with a support force to return to its original position.

[0043] In some embodiments, a second limiting component 26 is further included, which clamps the elastic platform component 23 on both sides along a second direction to clamp and position the elastic platform component 23. Based on the above structure, it is ensured that when the elastic platform component 23 is subjected to force and may displace, its movement in the second direction can be effectively controlled within a certain range, thereby avoiding excessive extension or offset and maintaining the stability and accuracy of the internal mechanical structure of the pre-embedded device 2. Through this dual-limiting design (first limiting component 224 and second limiting component 26), the pre-embedded device 2 can constrain and guide the elastic platform component 23 from multiple dimensions, improving the safety, reliability, and ease of operation of the overall device during construction.

[0044] It should be noted that the second direction in this embodiment is parallel to the long side of the elastic platform component 23.

[0045] Specifically, in this embodiment, the second limiting component 26 includes two opposing second limiters 261, which are disposed opposite to each other on the other two sides of the elastic platform component 23, ensuring that the second limiters 261 effectively limit and support the elastic platform component 23 from both sides.

[0046] It should be noted that in this embodiment, one end of the second limiter 261 is connected to the first force-bearing platform 231, and the other end is engaged with the second force-bearing platform 232; or one end of the second limiter 261 is connected to the second force-bearing platform 232, and the other end is engaged with the first force-bearing platform 231.

[0047] In some embodiments, the second connecting assembly 25 includes a connecting pipe 251, a base plate 252, and a fixing nut 253. One end of the connecting pipe 251 is fixed to the elastic platform assembly 23, and the other end of the connecting pipe 251 is fixed to the base plate 252. The base plate 252 is fixed to the side plate 242, which is disposed opposite to the connecting plate 241, by the fixing nut 253.

[0048] Based on the above structure, the base plate 252 plays a supporting and connecting role, combining the connecting pipe 251 with the side plate 242 in the pre-embedded housing 24, which enhances the stability of the overall structure. When the elastic platform component 23 is subjected to force, this force can be effectively transmitted to other parts of the device through the connecting pipe 251.

[0049] In summary, the embodiments of the present invention provide a pre-embedded device 2 and an aluminum formwork structure for the construction of aluminum formwork 1, which is easy to install, easy to dismantle and simple to operate, reducing the process and subsequent personnel repairs, reducing the input of manpower and material resources, and reducing costs.

[0050] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
