Description

Technical Field

[0001] This application relates to the field of thermal insulation structures, and in particular to a thermal insulation device for aluminum formwork. Background Technology

[0002] When constructing walls using cast-in-place concrete, the concrete is poured into the erected aluminum formwork. Once the concrete has cured to the point where it meets the demolding requirements, the aluminum formwork is removed. During the concrete curing process, it is crucial to ensure that the curing temperature reaches the standard conditions for concrete samples as closely as possible. This reduces the risk of cracks forming in the wall due to excessive heat or cold during curing, thus improving the overall quality of the wall. To minimize the temperature difference between the concrete surface and the interior, an insulation structure is installed on the aluminum formwork surface to prevent the concrete temperature from dropping too low.

[0003] For example, in related technologies, in order to insulate the aluminum formwork, a mounting plate is fixed to the outside of the aluminum formwork with screws. Insulation materials such as insulation cotton are attached to the side of the mounting plate closest to the aluminum formwork so as to insulate the aluminum formwork and the concrete inside the aluminum formwork.

[0004] Regarding the relevant technology, when fixing the mounting plate to the outside of the aluminum formwork, some workers need to support the mounting plate to initially fix it to the aluminum formwork. At the same time, other workers then fix the mounting plate to the aluminum formwork with screws to secure the aluminum formwork to the insulation structure. However, this operation method requires the cooperation of people supporting and fixing the insulation plate, which is quite inconvenient. Therefore, providing a device that facilitates the installation of the insulation structure onto the aluminum formwork is an urgent problem to be solved. Summary of the Invention

[0005] To facilitate the installation of insulation structures onto aluminum formwork, this application provides an insulation device for aluminum formwork.

[0006] The thermal insulation device for aluminum molds provided in this application adopts the following technical solution:

[0007] A thermal insulation device for aluminum formwork includes a first connecting plate, multiple plug-in components, and multiple flexible thermal insulation components;

[0008] The flexible insulation component is shaped like an open bag, and each of the plug-in components is fitted with a flexible insulation component around its outer periphery;

[0009] The plug-in assembly includes a first elastic member and a pusher member. The first elastic member is located between the pusher member and the first connecting plate, and the first elastic member has a force that pushes the pusher member to slide in a deformed state, so as to increase the distance between the pusher member and the first connecting plate.

[0010] By adopting the above technical solution, when it is necessary to insulate the aluminum mold, the first connecting plate is moved so that multiple flexible insulation components and plug-in components are inserted into the outer groove of the aluminum mold. Some plug-in components are squeezed by the side edges of the aluminum mold, causing the first elastic component to compress and deform. Finally, the first connecting plate is fixed to the side edges of the aluminum mold, and the aluminum mold can be insulated by multiple flexible insulation components. Since the inner cavity of the aluminum mold varies in size, the first elastic component can be squeezed by the side edges at any position, making the entire insulation device highly versatile. In addition, since the pushing component and the first elastic component are not flexible structures, the plug-in components can be hung on the horizontally set side edges. Therefore, when installing the entire insulation device, personnel only need to move the insulation device towards the aluminum mold so that the plug-in components can be hung on the side edges. During the process of fixing the first connecting plate to the aluminum mold, there is no need for too many personnel to support the insulation components, which facilitates the installation of the insulation device.

[0011] Optionally, it may also include a fastening component, which is disposed on the plug-in component;

[0012] The fastening assembly includes a fastening plate and a third elastic element;

[0013] The third elastic element is fixed between the fastening plate and the pushing member, and the third elastic element has a force that drives the fastening plate to slide in the deformed state, so as to increase the distance between the fastening plate and the pushing member along the direction perpendicular to the elastic extension and contraction of the first elastic element.

[0014] When the fastening plates connected to two adjacent pushing members come into contact with each other, the third elastic member is in a deformed state.

[0015] By adopting the above technical solution, when the side edge squeezes and deforms part of the plug-in component, the fastening plates on the plug-in components on both sides of the squeezed plug-in component will move toward the side edge of the aluminum mold during the process of the third elastic element recovering its deformation, so as to clamp the side edge of the aluminum mold. By setting the fastening component, before the first connecting plate is completely fixed to the aluminum mold, the aluminum mold and the first connecting plate can be initially fixed by the fastening component, without the need for other personnel to fix the first connecting plate to the aluminum mold during the process of fixing the aluminum mold and the first connecting plate.

[0016] Optionally, the fastening assembly further includes a guide member, one end of which is fixedly connected to the push member and the other end of which is fixedly connected to the fastening plate; the guide member extends from the push member to the fastening plate and is inclined toward the direction close to the first connecting plate.

[0017] When an external force is applied to the guide member from the fastening plate to one side of the guide member, the degree of deformation of the guide member gradually increases. During the process of the guide member returning to its normal state from the deformed state, it has a force that drives the fastening plate to move, so as to increase the distance between the fastening plate and the pusher member.

[0018] By adopting the above technical solution, when the side edge of the aluminum mold squeezes part of the plug-in component, if the side edge of the aluminum mold comes into contact with the guide, the aluminum mold will move along the guide and transition to the side of the fastening plate away from the pushing component, thereby avoiding the situation where the side edge of the aluminum mold and the fastening component get stuck.

[0019] Optionally, the flexible insulation component is provided with a heating wire.

[0020] By adopting the above technical solution, if the ambient temperature is too low during the concrete curing process, the heating wire can be energized to heat the flexible insulation component, which then transfers the heat to the aluminum mold.

[0021] Optionally, the first connecting plate has a receiving groove on the side near the flexible insulation component, and the open end of the flexible insulation component is located in the receiving groove.

[0022] By adopting the above technical solution, when the plug-in component is squeezed by the side edge of the aluminum mold, the flexible insulation component will also be squeezed by the side edge of the aluminum mold. During this process, the end of the flexible insulation component near its own opening can be squeezed into the receiving groove for storage, which can provide storage space for the squeezed and stacked flexible insulation components.

[0023] Optionally, it also includes a tensioning component, which includes a second elastic element. One end of the second elastic element is fixedly connected to the flexible insulation element, and the other end is connected to the first connecting plate. When the first elastic element is in a normal state, the second elastic element is in a deformed state. As the first elastic element gradually deforms, the second elastic element gradually recovers its deformation. In the deformed state, the second elastic element has a force that pulls the flexible insulation element toward the receiving groove.

[0024] By adopting the above technical solution, during the process of the plug-in component being squeezed, the first elastic element gradually changes from the normal state to the deformed state. During this process, the second elastic element gradually returns from the deformed state to the normal state and pulls the flexible insulation component into the receiving groove, which can keep the flexible insulation component on the outer periphery of the plug-in component in a relatively flat state.

[0025] Optionally, the tensioning assembly further includes a second connecting plate and a first locking member. The second connecting plate is located within the receiving groove, and a receiving gap is formed between the second connecting plate and the bottom and wall of the receiving groove. The open end of the flexible insulation member is located within the receiving gap, and the receiving gap is used to accommodate the flexible insulation member. The first locking member is connected between the second connecting plate and the first connecting plate to connect the first connecting plate and the second connecting plate.

[0026] The end of the first elastic member away from the pushing member is connected to the second connecting plate.

[0027] By adopting the above technical solution, the second connecting plate is connected to the first connecting plate through the first locking member, which facilitates the connection of the plug-in component to the first connecting plate through the second connecting plate. It also allows personnel to directly install the plug-in component and the second connecting plate onto the first connecting plate after the plug-in component is manufactured in the factory, thus enabling modular assembly operations.

[0028] Optionally, the second elastic member is located within the receiving gap between the second connecting plate and the bottom of the receiving groove, and the open end of the flexible insulation member is located within the receiving gap between the second connecting plate and the bottom of the receiving groove.

[0029] By adopting the above technical solution, the open end of the flexible insulation component is located in the receiving gap between the second connecting plate and the bottom of the receiving groove. The second connecting plate blocks the flexible insulation component, which can reduce the problem of the flexible insulation component sliding out of the receiving gap.

[0030] Optionally, it also includes a fixing component, which includes a retainer and a second locking member; the retainer is connected to the first connecting plate, and the second locking member is connected to the retainer; when the retainer is fixed to the aluminum mold, the second locking member is used to fix the retainer to the side edge of the aluminum mold.

[0031] By adopting the above technical solution, when it is necessary to fix the first connecting plate to the aluminum mold, the second locking member fixes the first connecting plate to the side edge of the aluminum mold, which can prevent the first connecting plate from falling off the aluminum mold and improve the firmness of the connection between the first connecting plate and the aluminum mold.

[0032] Optionally, the fixing assembly further includes a second telescopic rod, one end of which is fixedly connected to the first connecting plate and the other end of which is fixedly connected to the card holder, so as to change the distance between the card holder and the first connecting plate.

[0033] By adopting the above technical solution, if the gap between the card holder and the side edge of the aluminum mold is large, the distance between the card holder and the aluminum mold can be changed by the second telescopic rod, which can adapt to the use of different types of aluminum molds.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. In this application, the plug-in component can be hung on the horizontally set side edge, so that when the personnel are installing the entire insulation device, they only need to move the insulation device toward the aluminum mold so that the plug-in component can be hung on the side edge; during the process of fixing the first connecting plate to the aluminum mold, there is no need for too many personnel to support the insulation component, which makes it convenient for personnel to carry out the installation work of the insulation device.

[0036] 2. The installation of fastening components further facilitates the installation of the insulation device onto the aluminum formwork;

[0037] 3. By setting up fixing components, the insulation device can be prevented from falling off the aluminum mold. Attached Figure Description

Detailed Implementation

[0047] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0048] This application discloses a heat preservation device for aluminum molds. (Refer to...) Figure 1 The thermal insulation device for aluminum formwork includes a first connecting plate 1, a plug-in assembly 2, and multiple flexible thermal insulation components 3. The first connecting plate 1 is a rectangular plate, and the plug-in assemblies 2 are distributed in a matrix on the surface of the first connecting plate 1. The flexible thermal insulation components 3 are bag-shaped with one end open. Each flexible thermal insulation component 3 is sleeved on the outer periphery of a plug-in assembly 2, and the open end of the flexible thermal insulation component 3 is fixedly connected to the first connecting plate 1. Therefore, multiple flexible thermal insulation components 3 are also distributed in a matrix on the surface of the first connecting plate 1.

[0049] Reference Figure 1 and Figure 2 The plug-in assembly 2 includes a pusher 21, a first elastic member 22, and a first telescopic rod 23. The pusher 21 is a square plate, and its surface is parallel to the surface of the first connecting plate 1. The first elastic member 22 is a compression spring. One end of the first elastic member 22 is welded to the pusher 21, and the other end is welded to the first connecting plate 1. The elastic extension direction of the first elastic member 22 is perpendicular to both the surface of the first connecting plate 1 and the surface of the pusher 21, so that the pusher 21 is elastically connected to the first connecting plate 1 through the first elastic member 22. When compressed, the first elastic member 22 has a force that drives the pusher 21 to move away from the first connecting plate 1. One end of the first telescopic rod 23 is welded to the pusher 21, and the other end is welded to the first connecting plate 1. The extension direction of the first telescopic rod 23 is parallel to the elastic extension direction of the first elastic member 22. Specifically, the first elastic member 22 is sleeved on the outer periphery of the first telescopic rod 23.

[0050] Reference Figure 3 In order to improve the heat preservation effect of the flexible insulation component 3, an electric heating wire 31 is embedded in the flexible insulation component 3 to transfer heat by heating the electric heating wire 31. In order to further improve the heat preservation effect, a pile is attached to the surface of the flexible insulation component 3, thereby reducing the heat transfer effect through the flexible insulation component 3.

[0051] Reference Figure 2 and Figure 3 In addition, to ensure that the flexible insulation component 3 is kept as taut as possible, a tensioning assembly 4 is provided on the first connecting plate 1. The tensioning assembly 4 includes a second connecting plate 41, a first locking component 42, and multiple second elastic components 43. A receiving groove 11 is provided on the side of the first connecting plate 1 near the pushing component 21. The second connecting plate 41 is located in the receiving groove 11. The first locking component 42 is a bolt. The first locking component 42 passes through the first connecting plate 1 and is threadedly connected to the first connecting plate 1. After passing through the first connecting plate 1, the first locking component 42 is rotatably connected to the second connecting plate 41. The first locking component 42 is parallel to the extension and contraction direction of the first elastic component 22 along the rotation axis of the second connecting plate 41. A receiving gap 12 is formed between the second connecting plate 41 and the bottom of the receiving groove 11. The second elastic components 43 are tension springs. Multiple second elastic components 43 are located on the second connecting plate 41. Within the receiving gap 12 between the connecting plate 41 and the bottom of the receiving groove 11, the open end of the flexible insulation component 3 passes through the gap between the side wall of the second connecting plate 41 and the side wall of the receiving groove 11 and is then housed within the receiving gap 12. One end of the second elastic component 43 is fixedly connected to the flexible insulation component 3, and the other end is fixedly connected to the first locking component 42. When the first elastic component 22 changes from its normal state to its deformed state, the second elastic component 43 gradually changes from its deformed state back to its normal state. In its deformed state, the second elastic component 43 has a force that pulls the flexible insulation component 3 toward the first locking component 42. Therefore, after the first elastic component 22 and the first telescopic rod 23 are compressed, the flexible insulation component 3 will be housed within the receiving gap 12 as much as possible under the pull of the second elastic component 43, which can, to a certain extent, prevent the flexible insulation component 3 from being clamped into the threaded gap of the first elastic component 22.

[0052] Reference Figure 4 and Figure 5 When the heat preservation device needs to be installed on the aluminum mold, the first connecting plate 1 is moved so that part of the plug-in component 2 is embedded in the outer groove 01 of the aluminum mold. At this time, part of the plug-in component 2 is pushed by the side edge 02 of the aluminum mold so that the first elastic member 22 is compressed. In order to facilitate the fixing of the plug-in component 2 to the side edge 02 of the aluminum mold, a fastening component 5 is provided on the pushing member 21. In this embodiment, a fastening component 5 is provided on each side wall of the pushing member 21.

[0053] Reference Figure 5 and Figure 6The fastening assembly 5 includes a fastening plate 51, a third elastic element 52, and a guide element 53. The fastening plate 51, located on the side wall of each plate of the pushing member 21, is parallel to the side wall of the pushing member 21 that it faces, that is, the fastening plate 51 is set perpendicular to the first connecting plate 1. The third elastic element 52 is a compression spring. One end of the third elastic element 52 is welded to the first connecting plate 1, and the other end is welded to the fastening plate 51. In the compressed state, the third elastic element 52 has a force that pushes the fastening plate 51 toward the side away from the first connecting plate 1, so that the fastening plate 51 achieves an elastic connection with the first connecting plate 1 through the third elastic element 52. When the side edge 02 of the aluminum mold is not inserted between two adjacent pushing members 21, the fastening plates 51 between the two adjacent pushing members 21 are in a mutually pressing state under the support of the third elastic element 52.

[0054] Reference Figure 5 and Figure 6 One end of the guide member 53 is fixedly connected to the push member 21, and the other end is fixedly connected to the fastening plate 51. The guide member 53 is made of a material that can recover its deformation after deformation, such as elastic steel sheet or other materials that can recover their deformation after deformation. The guide member 53, which connects the push member 21 and the fastening plate 51, is inclined towards the side closer to the first connecting plate 1 from the push member 21 to the fastening plate 51. When the side edge 02 of the aluminum mold is inserted between two adjacent plug-in components 2, the side edge 02 of the aluminum mold will first contact the guide member 53. Since the guide member 53 is inclined towards the first connecting plate 1, the side edge 02 of the aluminum mold will gradually transition to the side of the fastening plate 51 away from the pushing member 21 under the guidance of the guide member 53. During this process, the third elastic member 52 and the guide member 53 will be gradually compressed and deformed. The compressed and deformed third elastic member 52 and the guide member 53 will push the fastening plate 51 to press against the side edge 02 of the aluminum mold. The side edge 02 of the aluminum mold will be clamped by the fastening plates 51 on both sides of the long side of the side edge 02.

[0055] Reference Figure 6 and Figure 7 To ensure that the fastening plate 51 can clamp the side edge 02 of the aluminum mold, the first elastic member 22 forms a clearance gap 13 between the fastening plate 51 and the first connecting plate 1 in the normal state. When part of the plug-in component 2 is pressed by the side edge 02 of the aluminum mold, the fastening plate 51 on the pressed plug-in component 2 loses the pressure of the other fastening plates 51. Therefore, the fastening plate 51 and part of the guide member 53 on the pressed plug-in component 2 can be inserted into the clearance gap 13 next to it. The force of the side edge 02 of the squeezed plug-in component 2 entering the clearance gap 13 is the force generated when the third elastic member 52 in the deformed state recovers its deformation.

[0056] Reference Figure 8Furthermore, in order to fix the first connecting plate 1 to the side edge 02 of the aluminum mold, a fixing component 6 is provided on the outer periphery of the first connecting plate 1. The fixing component 6 includes a card seat 61, a second locking member 62, and a second telescopic rod 63. The card seat 61 has a slot 611 for the side edge 02 of the aluminum mold to be inserted. The second locking member 62 is a bolt, which is threaded to the card seat 61. After passing through the side wall of the card seat 61, the second locking member 62 abuts against the side wall of the side edge 02 away from the outer groove 01 of the aluminum mold. One end of the second telescopic rod 63 is fixedly connected to the card seat 61, and the other end is fixedly connected to the side wall of the first connecting plate 1. The extension and retraction direction of the second telescopic rod 63 is parallel to the surface of the first connecting plate 1, so as to realize the change of the distance between the first connecting plate 1 and the card seat 61 through the second telescopic rod 63.

[0057] The implementation principle of the heat preservation device for aluminum mold in this application embodiment is as follows: During operation, the operator picks up a heat preservation device and moves it to the aluminum mold. Then, the heat preservation device is pushed towards the side of the aluminum mold so that the side edge 02 of the aluminum mold squeezes part of the plug-in component 2. During this process, due to the presence of the guide 53, the side edge 02 of the aluminum mold will slide along the guide 53 to the side wall of the fastening plate 51. Then, the third elastic member 52 can push the fastening plate 51 towards the side edge 02 of the aluminum mold so that the fastening plates 51 on both sides of the side edge 02 of the aluminum mold can clamp the side edge 02 of the aluminum mold.

[0058] Before bringing the insulation device closer to the aluminum mold, the personnel can adjust the second telescopic rod 63 to the required length in advance to ensure that the side edge 02 of the aluminum mold can be embedded in the slot 611. After the side edge 02 of the aluminum mold is embedded in the slot 611, the card seat 61 can be fixed to the side edge 02 of the aluminum mold by the second locking member 62.

[0059] After the insulation device is installed on the aluminum formwork, it will keep the aluminum formwork and the concrete inside it warm. If necessary, the heating wire 31 can also be energized to further increase the temperature of the aluminum formwork.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
