Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an aluminum alloy formwork for integral molding of concrete secondary structures. Background Technology

[0002] Aluminum alloy formwork is a type of building formwork made of aluminum alloy, used to improve the efficiency of building construction projects.

[0003] In traditional construction processes, secondary structures (construction columns and lintels) need to be constructed after the main structure is completed. This process is time-consuming, involves complicated processes such as drilling and rebar installation, and is prone to rebar misalignment. Therefore, aluminum alloy formwork is used for detailed design and one-time construction of secondary components. The construction process is as follows: measuring the defense line - binding the reinforcement of the construction column with the main structure - formwork acceptance - beam formwork installation - floor slab installation - binding the reinforcement of the lintel with the reinforcement of the structural beams and slabs - reinforcement acceptance - pouring concrete - demolding - transfer to the next floor.

[0004] The integrated construction process described above shortened the construction period, increased revenue, and reduced quality risks such as misalignment. However, during construction, it was found that when adjacent aluminum alloy formwork was assembled and fixed using fasteners, the formwork lacked restraints and was prone to wobbling, making fastener installation difficult (e.g., bolts and threaded holes were not easily aligned), resulting in low installation efficiency. Therefore, further improvements are needed to prevent the aluminum alloy formwork from wobbling during installation and to improve the installation efficiency of fasteners. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides an aluminum alloy formwork for integral molding of secondary concrete structures, which solves the technical problem in related technologies that aluminum alloy formwork is prone to shaking during assembly, resulting in inconvenient installation of fasteners.

[0006] According to one aspect, at least one embodiment of the present invention provides an aluminum alloy template for integral molding of secondary concrete structures, comprising a main body having two opposing assembly ends, an assembly end one having a through groove, a locking member having a swinging action at one end of the through groove, the swinging axis of the locking member being parallel to the extension direction of the main body, an opening at the bottom of the locking member, a locking member having a swinging action within the locking member, the swinging axis of the locking member being perpendicular to the swinging axis of the locking member, the locking member being configured to extend out of the opening after swinging, an assembly end two adjacent to the main body having a through groove two corresponding to the through groove one on the adjacent main body, a locking member two being provided on the side wall of the main body inside the through groove two, an opening two being provided at the top of the locking member two, the locking member being configured to follow the locking member one as it moves through the through groove two and then engage in the opening two to lock the adjacent aluminum alloy template.

[0007] For example, at least one embodiment of this disclosure provides an aluminum alloy template for integral molding of a secondary concrete structure, wherein a second locking member is provided with a second oscillating member, the oscillation axis of the second locking member is parallel to the oscillation axis of the first locking member, and the second locking member is configured to extend out of the second opening after oscillation to engage with the first opening to lock the adjacent aluminum alloy template.

[0008] For example, at least one embodiment of this disclosure provides an aluminum alloy template for integral molding of a secondary concrete structure, wherein both the second clamp and the first clamp are semi-circular, and the first clamp is configured to snap into the second opening and fit together with the second clamp to form a complete circle.

The top of the locking member 1 has a clearance opening 1, and the locking member 1 is provided with an extension rod 1. The extension rod 1 has a force-receiving part 1 and a force-receiving part 2 connected to each other. The force-receiving part 1 is located inside the locking member 1 and is connected to the inner wall of the locking member 1 through an elastic member 1. The elastic member 1 is used to provide a force for the locking member 1 to swing outward toward the opening 1. The force-receiving part 2 extends out of the clearance opening 1 and is configured to allow the locking member 1 to disengage from the opening 2 after being manually pushed to overcome the elastic force of the elastic member 1.

[0010] For example, at least one embodiment of this disclosure provides an aluminum alloy template for integral molding of a secondary concrete structure. The bottom of the locking member 2 has a clearance opening 2. The locking member 2 is provided with an extension rod 2. The extension rod 2 has a force-receiving part 3 and a force-receiving part 4 connected to each other. The force-receiving part 3 is located inside the locking member 2 and is connected to the inner wall of the locking member 2 through an elastic member 2. The elastic member 2 is used to provide a force for the locking member 2 to swing outward toward the opening 2. The force-receiving part 4 extends out of the clearance opening 2 and is configured to allow the locking member 2 to disengage from the opening 1 after being manually pushed to overcome the elastic force of the elastic member 2.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0027] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-2 As shown, this invention illustrates an aluminum alloy template for integral molding of a secondary concrete structure according to one embodiment of the present invention. In some examples, the main body 1 has two opposing assembly ends, 2 and 3. The assembly end 2 has a through groove 21, and a locking element 22 is oscillatingly installed at the through groove 21 via a hinge axis. The oscillation axis of the locking element 22 is parallel to the extension direction of the main body 1. An opening 221 is provided at the bottom of the locking element 22. A clamping element 222 is oscillatingly installed inside the locking element 22 via a hinge axis. The oscillation axis of the clamping element 222 is perpendicular to the oscillation axis of the locking element 22. The clamping element 222 can oscillate around its own hinge axis and extend out of the opening 221. The adjacent assembly end 3 of the main body 1 has a through groove 31 corresponding to the through groove 21. A locking element 32 is fixed on the side wall of the main body 1 inside the through groove 31. An opening 321 is provided at the top of the locking element 32.

[0033] Its working principle is as follows: the correspondence between through slot 1 21 and through slot 2 31 provides a moving guide for locking component 1 22. When not in use, locking component 1 22 swings back to the inside of the main body 1. When in use, it swings out to the outside. During assembly, the assembly end 1 2 and assembly end 2 3 of the adjacent main body 1 are aligned so that through slot 1 21 and through slot 2 31 are aligned. Locking component 1 22 is swung to the outside of the main body 1 and aligned with through slot 2 31 of the adjacent main body 1. When it passes through through slot 2 31 and moves to the position of locking component 1 222 reaching the position of opening 2 321, locking component 1 222 is swung to extend out of opening 1 221 and lock into opening 2 321, thus completing the locking of the adjacent aluminum alloy template.

[0034] For example, such as Figure 2 As shown, the advantages of this setting are: the corresponding setting of through slot 1 21 and through slot 2 31 restricts the relative swaying of adjacent main bodies 1 in the direction perpendicular to the assembly direction; after the clip 1 222 is inserted into the opening 2 321, it forms a horizontal limit; the combination of multiple limits effectively prevents the aluminum alloy template from swaying during the installation process, eliminating the need to repeatedly adjust the position of the main body 1 to find the fastener position, improving the installation efficiency of fasteners between adjacent aluminum alloy templates, and solving the problem of inconvenient fastener installation caused by template swaying in traditional assembly.

[0035] like Figures 1-2 As shown, it illustrates an aluminum alloy template for integral molding of a secondary concrete structure in one embodiment of the present invention. In some examples, a locking member 2 322 is oscillatingly installed inside the locking member 2 32 via a hinge shaft. The oscillation axis of the locking member 2 322 is parallel to the oscillation axis of the locking member 1 222. The locking member 2 322 can oscillate around its own hinge shaft and extend out of the opening 2 321, and can be inserted into the opening 1 221.

[0036] Its working principle is as follows: after the first clip 222 is inserted into the second opening 321, the second clip 322 is swung to extend out of the second opening 321 and insert into the first opening 221. The two layers are locked together to lock the adjacent aluminum alloy template.

[0037] For example, such as Figure 2 As shown, the advantage of this setting is that card part 2 322 and card part 1 222 form two locking connections. Compared with the single locking connection of card part 1 222, the loosening of the locking connection caused by unidirectional force is reduced, which further enhances the stability of the locking, more effectively prevents the template from shaking, and improves the efficiency and reliability of assembly locking.

[0038] like Figures 3-6 As shown, it illustrates an aluminum alloy template for integral molding of concrete secondary structures in one embodiment of the present invention. In some examples, both the second clip 322 and the first clip 222 are semi-circular. When the first clip 222 is inserted into the second opening 321, the first clip 222 and the second clip 322 fit together to form a complete circle.

[0039] Its working principle is as follows: after clip 222 is inserted into opening 321 and clip 322 is inserted into opening 221, the semi-circular surfaces of the two clips fit together to form a complete circle. The adaptability of the semi-circular structure forms a complete circular engagement. Arc-shaped contact surfaces are also provided on openings 221 and 321 to fit with clips 322 and 222, respectively. Uniform force is achieved through the contact of the circular contact surfaces.

[0040] For example, such as Figure 4 , Figure 6 As shown, the advantages of this arrangement are: the semi-circular clip 222 and clip 322 fit together to form a complete circle. By utilizing the symmetry of the circular structure and the arc-shaped contact surfaces on opening 221 and opening 321, the load can be evenly transferred when both are subjected to force. This avoids the failure of the clip caused by excessive local stress due to irregular shape, enhances the stability of the clip, more effectively prevents the template from shaking, and improves the reliability and efficiency of assembly and locking.

[0041] like Figures 3-6As shown, it illustrates an aluminum alloy template for integral molding of a secondary concrete structure according to an embodiment of the present invention. In some examples, the top of the locking member 22 is provided with a clearance opening 223. An extension rod 2221 is fixed on the locking member 222. The extension rod 2221 has a connected force-receiving part 2222 and a force-receiving part 2223. The force-receiving part 2222 is located inside the locking member 22 and is connected to the inner wall of the locking member 22 through an elastic member 224. The elastic member 224 can provide a force for the locking member 222 to swing outward toward the opening 221. The force-receiving part 2223 extends out of the clearance opening 223. Manually pushing the force-receiving part 2223 can overcome the elastic force of the elastic member 224 and cause the locking member 222 to disengage from the opening 221.

[0042] Its working principle is as follows: During installation, the elastic force of the elastic element 224 pushes the locking element 222 to automatically extend out of the opening 221 and engage with the opening 321; during unlocking, the force-receiving part 2223 is pushed, and the extension rod 2221 causes the locking element 222 to overcome the elastic force and swing out of the opening 321. The elastic element 224 enables the locking element 222 to automatically engage, and the extension rod 2221 enables convenient unlocking, while the opening 223 provides space for the force-receiving part 2223 to move.

[0043] For example, such as Figure 4 As shown, the advantages of this design are: the elastic element 224 allows the locking element 222 to automatically engage with the opening 321, reducing manual operation steps and improving locking efficiency; the force-bearing part 2223 of the extension rod 2221 facilitates the application of external force, making unlocking operation convenient; the cooperation between the elastic element 224 and the extension rod 2221 ensures the reliability of the engagement and enables rapid unlocking; combined with the guiding effect of the through slot 21 and the through slot 31, the overall efficiency of template assembly and disassembly is further improved, solving the problem of cumbersome disassembly and assembly of traditional fasteners.

[0044] like Figures 2-6 As shown, it illustrates an aluminum alloy template for integral molding of a secondary concrete structure according to an embodiment of the present invention. In some examples, the bottom of the locking member 2 32 is provided with a clearance opening 2 323. An extension rod 2 3221 is fixed on the locking member 2 322. The extension rod 2 3221 has a connected force-bearing part 3 3222 and a force-bearing part 4 3223. The force-bearing part 3 3222 is located inside the locking member 2 32 and is connected to the inner wall of the locking member 2 322 through an elastic member 2 324. The elastic member 2 324 can provide a force for the locking member 2 322 to swing outward toward the opening 2 321. The force-bearing part 4 3223 extends out of the clearance opening 2 323. Manually pushing the force-bearing part 4 3223 can overcome the elastic force of the elastic member 2 324 and cause the locking member 2 322 to disengage from the opening 1 221.

[0045] Its working principle is as follows: During installation, the elastic force of the elastic element 2 324 pushes the locking element 2 322 to automatically extend out of the opening 2 321 and lock into the opening 1 221; during unlocking, the force-receiving part 4 3223 is pushed, and the extension rod 2 3221 drives the locking element 2 322 to overcome the elastic force and swing out of the opening 1 221. When assembling adjacent aluminum alloy templates, locking component 1 22 is inserted into through slot 2 31. Locking component 1 222 is pushed into locking component 1 22 by the top surface of locking component 2 32, forming a horizontal semicircle. Similarly, locking component 2 322 is pushed into locking component 2 32 by the bottom surface of locking component 1 22, also forming a horizontal semicircle. When locking component 1 222 encounters opening 2 321, locking component 2 322 also aligns with opening 1 221. Both components swing into inclined semicircles under elastic action and press tightly against each other, thus forming a lock. If the two main bodies 1 tend to shake, either locking component 1 222 and opening 2 321 or locking component 2 322 and opening 1 221 will engage, or the elastic force on locking component 1 222 and locking component 2 322 needs to be overcome. Therefore, shaking can be effectively prevented. Figure 2 As shown, when the left main body 1 has a tendency to sway to the left, it is necessary to overcome the locking force of the first locking piece 222 and the second opening 321. When it has a tendency to sway to the right, it is necessary to overcome the elastic force of the first locking piece 222 and the second locking piece 322. Compared with the design of positioning holes and positioning pins, this structure can be automatically locked, and the locking piece 22 will not get stuck or jammed when it enters the through slot 31, making it more convenient to use.

[0046] For example, such as Figure 5 As shown, the advantages of this configuration are: the elastic element 2 324 allows the locking element 2 322 to automatically engage with the opening 1 221, and the cooperation with the elastic element 224 achieves bidirectional automatic locking, reducing manual locking steps and improving locking efficiency and reliability; the force-bearing part 4 3223 of the extension rod 2 3221 facilitates the application of external force, making the unlocking operation convenient. Combined with the bidirectional locking structure, it ensures a stable lock while achieving quick disassembly and assembly, further improving the template turnover efficiency and solving the problem of time-consuming disassembly and assembly of traditional fasteners.

[0047] like Figure 2 As shown, it illustrates an aluminum alloy template for integral molding of a secondary concrete structure in one embodiment of the present invention. In some examples, a limiting plate 23 is hinged to the assembly end 2 via a hinge shaft. The limiting plate 23 is located on one side of the locking member 22 and can swing around its own hinge shaft and abut against the locking member 22.

[0048] Its working principle is as follows: When the locking element 22 swings to the locked position and the latch 222 engages with the opening 321, the swing limiting plate 23 is used to press against the locking element 22, preventing it from swinging away from the through slot 31. To unlock, the limiting plate 23 is first used to disengage the locking element 22, and then the locking element 22 is operated to swing. The contact between the limiting plate 23 and the locking element 22 restricts the swing of the locking element 22, enhancing its stability in the locked position.

[0049] For example, such as Figure 2 As shown, the advantages of this setting are: the contact between the limiting plate 23 and the locking part 22 restricts the reverse swing of the locking part 22, and the engagement with the latch 222 fixes the position of the locking part 22 from two dimensions, preventing the locking part 22 from accidentally swinging due to vibration or other factors during construction, which would cause the latch to loosen. This further enhances the stability of the locking structure, ensures that adjacent formwork remains stable during concrete pouring and other construction processes, reduces formwork shaking caused by accidental movement of the locking part, and improves the reliability of the overall structure.

[0050] In one embodiment of this utility model, an aluminum alloy template for integral molding of a secondary concrete structure is provided. In some examples, the bottom surface of locking member 22 and the top surface of locking member 32 are provided with anti-slip protrusions.

[0051] After locking element 22 passes through through groove 31, the bottom surface of locking element 22 contacts the top surface of locking element 32, and the anti-slip protrusions of both interlock, restricting relative sliding. The anti-slip protrusions increase the friction when locking element 22 and locking element 32 are in contact, reducing relative sliding.

[0052] The advantage of this design is that the anti-slip protrusions increase the friction between locking element 22 and locking element 32, further improving the stability of the lock.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
