The implementation of aluminum formwork construction requires stable design drawings, which in turn promotes the standardization process of products.

[0003] However, using aluminum alloy formwork exclusively also presents some problems, such as the need for a large quantity of aluminum alloy formwork and high rental costs. Furthermore, all formwork requires erection and dismantling, which takes considerable time and extends the construction period.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

The overlapping fitting has a top overlapping plate, the width of which is greater than the thickness of the aluminum alloy formwork. A steel truss floor deck, wherein the steel truss floor deck is supported on the top lap plate, and the top lap plate and the steel truss floor deck are detachably connected.

[0007] Optionally, each of the aluminum alloy templates includes multiple longitudinal templates, and the first casting cavity is formed between the longitudinal templates; The lap joint is located on the upper edge of the longitudinal template.

[0008] Optionally, the lap joint includes a bottom lap plate; The bottom overlapping plate and the top overlapping plate are spaced apart, and the bottom overlapping plate and the top overlapping plate are connected; The bottom overlapping plate is supported on the upper edge of the longitudinal template and is connected to the longitudinal template.

[0009] Optionally, the longitudinal template includes a main board and an edge guard plate disposed on the edge of the main board; The bottom overlapping plate is attached to the edge protector plate, and the bottom overlapping plate is fixedly connected to the edge protector plate.

[0010] Optionally, the width of the top overlap plate is greater than the width of the bottom overlap plate.

[0011] Optionally, the lap joint includes a connecting plate; The connecting plates are respectively vertically connected to the top overlapping plate and the bottom overlapping plate; The connecting plates of each overlapping component enclose a second casting cavity, which is connected to the first casting cavity.

[0012] Optionally, the steel truss floor deck includes galvanized profiled steel sheet and steel truss; The steel truss is arranged on one side of the galvanized profiled steel sheet along the thickness direction; The top overlapping plate is attached to the galvanized profiled steel sheet, and the top overlapping plate is connected to the galvanized profiled steel sheet by nails.

[0013] Optionally, the lap joint includes a side plate; The side panel is connected to the edge of the top overlapping plate on the side opposite to the connecting plate, and the side panel extends toward the bottom overlapping plate, with a gap between the side panel and the bottom overlapping plate.

[0014] Optionally, the prefabricated construction structure of floor decking combined with aluminum formwork includes aluminum formwork keel and support uprights; At least a portion of the aluminum formwork keel is located between adjacent aluminum alloy beam formwork assemblies and at the bottom of the steel truss floor slab; Each of the aforementioned support columns is supported at the bottom of the aluminum formwork keel.

[0015] Optionally, the prefabricated construction structure combining floor decking and aluminum formwork includes multiple connecting rods; Each of the supporting uprights is connected by the plurality of connecting rods to form an integral structure.

[0016] By adopting the above technical solution, this application has the following beneficial effects: First, the prefabricated construction structure of this application, combining floor decking with aluminum formwork, uses prefabricated steel truss floor decking supported at the floor slab. The steel truss floor decking is a composite formwork where the steel reinforcement in the floor slab is processed into steel trusses in a factory, and these trusses are welded to galvanized profiled steel sheets. During construction, the steel truss floor decking can be directly laid onto the beams according to the construction load, allowing for simple reinforcement work before concrete pouring. The steel truss floor decking is an integral part of the floor slab, completely replacing the formwork function, saving time on formwork erection and dismantling, and, combined with the aluminum formwork system, significantly accelerating construction speed—up to one floor every six days. Using steel truss floor decking instead of floor slab formwork greatly reduces the amount of aluminum alloy formwork used, saving on aluminum formwork rental costs.

[0017] Secondly, the steel truss floor deck is a cast-in-place concrete structure. The floor deck can be overlapped with the aluminum formwork, eliminating the need for stud welding work required in traditional steel structures and the construction work of pre-embedding angle steel for floor deck laying. The steel truss floor deck is prefabricated and delivered in the factory, reducing waste, saving steel reinforcement, saving on-site construction space, and improving processing quality and efficiency.

[0018] Third, an overlapping joint is provided, with the width of the top overlapping plate of the joint exceeding the thickness of the aluminum alloy formwork. This joint connects the aluminum alloy beam formwork assembly to the steel truss floor deck, increasing the support area and improving the stability of the steel truss floor deck. Furthermore, the extended top overlapping plate provides more operational space, facilitating the connection between the aluminum alloy beam formwork assembly and the steel truss floor deck. The extended top overlapping plate also compensates for manufacturing tolerances in the steel truss floor deck, ensuring stable and adequate support.

[0019] The prefabricated construction structure of floor decking combined with aluminum formwork in this application integrates the advantages of aluminum alloy formwork, steel truss floor decking, and lap joint components. It combines the advantages of floor decking combined with aluminum formwork, such as fast floor decking installation, less steel reinforcement binding, fewer support systems, and fast formwork removal, which greatly improves the construction speed of the structure.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figures 1 to 4As shown in the illustration, this application provides a prefabricated construction structure combining a floor deck slab and aluminum formwork, including an aluminum alloy beam formwork assembly, an overlapping fitting 2, and a steel truss floor deck slab 3. The aluminum alloy beam formwork assembly includes multiple aluminum alloy formwork panels 11, each of which encloses a first pouring cavity 41. The overlapping fitting 2 is disposed on the aluminum alloy beam formwork assembly and located around the top opening of the first pouring cavity 41. The overlapping fitting 2 has a top overlapping plate 21, the width of which is greater than the thickness of the aluminum alloy formwork panels 11. The steel truss floor deck slab 3 is supported on the top overlapping plate 21, and the top overlapping plate 21 and the steel truss floor deck slab 3 are detachably connected.

[0027] The prefabricated construction structure of this application, which combines floor decking with aluminum formwork, uses prefabricated steel truss floor decking 3 supported at the floor slab. The steel truss floor decking 3 is an integral part of the floor slab, completely replacing the formwork function, saving time on formwork erection and dismantling, and significantly accelerating construction speed when combined with the aluminum formwork system, allowing for rapid construction up to one floor every six days. Using steel truss floor decking 3 instead of floor slab formwork greatly reduces the amount of aluminum alloy formwork 11 used, saving on aluminum formwork rental costs.

[0028] Furthermore, the steel truss floor deck 3 is a cast-in-place concrete structure. The floor deck can be overlapped with the aluminum formwork, eliminating the need for stud welding work required in traditional steel structures and the construction work of pre-embedding angle steel for floor deck laying. The steel truss floor deck 3 is prefabricated and delivered in the factory, reducing waste, saving steel reinforcement, saving on-site construction space, and improving processing quality and efficiency.

[0029] One issue is that, due to the small width of the aluminum alloy formwork 11, the lap stability of the steel truss floor deck 3 directly overlapping the aluminum alloy beam formwork assembly is poor. Furthermore, the aluminum alloy beam formwork assembly and the steel truss floor deck 3 are positioned horizontally and vertically respectively, leaving no operational space for direct connection and making direct connection difficult. Additionally, the steel truss floor deck 3 may sometimes have manufacturing tolerances. When these tolerances exist, the small width of the aluminum alloy formwork 11 may prevent the aluminum alloy beam formwork assembly from properly lapping with the steel truss floor deck 3.

[0030] The prefabricated construction structure of this application, which combines a floor deck slab with aluminum formwork, is equipped with an overlapping joint 2. The width of the top overlapping plate 21 of the overlapping joint 2 is greater than the thickness of the aluminum alloy formwork 11. By using the overlapping joint 2 to connect the aluminum alloy beam formwork assembly and the steel truss floor deck slab 3, the support area of ​​the steel truss floor deck slab 3 can be increased, thereby improving the support stability of the steel truss floor deck slab 3. Furthermore, the extended top overlapping plate 21 provides more operating space, making the connection between the aluminum alloy beam formwork assembly and the steel truss floor deck slab 3 more convenient. The extended top overlapping plate 21 also compensates for the manufacturing tolerances of the steel truss floor deck slab 3, ensuring that the steel truss floor deck slab 3 is supported and stably supported.

[0031] Among them, the top lap plate 21 and the steel truss floor deck 3 are set to be detachably connected, so that the lap joint 2, like the aluminum alloy beam formwork assembly, can be reused, further reducing costs.

[0032] The prefabricated construction structure of floor decking combined with aluminum formwork in this application integrates the advantages of aluminum alloy formwork 11, steel truss floor decking 3, and lap joint fittings 2, and combines the advantages of floor decking combined with aluminum formwork. It has the advantages of fast floor decking laying, less steel reinforcement binding, less support system, and fast formwork removal, which greatly improves the construction speed of the structure.

[0033] Among them, the first pouring cavity 41 is part of the pouring cavity of the enclosed beam, and the entire beam pouring cavity 4 is formed by the comprehensive enclosed joint 2 and the steel truss floor deck 3.

[0034] In some possible implementations, each of the aluminum alloy templates 11 includes multiple longitudinal templates 111, horizontal templates 112, and end templates, forming the first casting cavity 41 between the longitudinal templates 111, horizontal templates 112, and end templates. The overlapping fitting 2 is disposed on the upper edge of the longitudinal template 111. This arrangement of the overlapping fitting 2 facilitates the connection with the longitudinal template 111, and provides the best support effect and strongest support stability by supporting the overlapping fitting 2 above the longitudinal template 111.

[0035] In some possible implementations, the overlapping fitting 2 includes a bottom overlapping plate 22, which is spaced apart from the top overlapping plate 21 and connected to it. The bottom overlapping plate 22 is supported on the upper edge of the longitudinal template 111 and connected to the longitudinal template 111.

[0036] In some possible implementations, the longitudinal template 111 includes a main board 1111 and an edge guard plate 1112 disposed along the edge of the main board 1111. The bottom overlapping plate 22 is attached to the edge guard plate 1112 and is fixedly connected to the edge guard plate 1112. The edge guard plate 1112 and the bottom overlapping plate 22 can increase the overlap area between the aluminum alloy beam template assembly and the overlapping fitting 2, ensuring the stability of the support.

[0037] The top lap plate 21 and the bottom lap plate 22 can both be connected to the aluminum alloy beam formwork assembly and the steel truss floor deck 3 via connectors, or the top lap plate 21 and the bottom lap plate 22 can both be connected to the aluminum alloy beam formwork assembly and the steel truss floor deck 3 by spot welding. Both have the characteristics of easy connection and easy disassembly.

[0038] In some possible implementations, the width of the top lap plate 21 is greater than the width of the bottom lap plate 22. The width of the bottom lap plate 22 only needs to be adapted to the width of the aluminum alloy beam formwork assembly and does not need to be too large. The width of the top lap plate 21 needs to provide stable support for the steel truss floor deck 3 and also needs to compensate for any possible production tolerances of the steel truss floor deck 3, therefore a larger width is required.

[0039] In some possible implementations, the lap joint 2 includes a connecting plate 23, which is vertically connected to the top lap plate 21 and the bottom lap plate 22, respectively. The connecting plates 23 of each lap joint 2 enclose a second pouring cavity 42, which communicates with the first pouring cavity 41. The top lap plate 21 and the bottom lap plate 22 are spaced apart and connected by side lap plates. The lap joint 2 is C-shaped, and the space in the middle of the lap joint 2 facilitates the connection between the lap joint 2 and the aluminum alloy beam formwork assembly and the steel truss floor deck 3.

[0040] Furthermore, a third casting cavity 43 is formed between the steel truss floor slabs 3. The third casting cavity 43 is connected to the second casting cavity 42. The first casting cavity 41, the second casting cavity 42 and the third casting cavity 43 together form the beam casting cavity 4.

[0041] In some possible implementations, the steel truss floor deck 3 includes a galvanized profiled steel sheet 31 and a steel truss 32. The steel truss 32 is disposed on one side of the galvanized profiled steel sheet 31 along its thickness direction. A top lap plate 21 is attached to the galvanized profiled steel sheet 31 and connected to the galvanized profiled steel sheet 31 by nails. The steel truss floor deck 3 is a composite formwork where the steel bars in the floor slab are processed into steel trusses 32 in a factory, and the steel trusses 32 are welded to the galvanized profiled steel sheet 31 as a whole. During the construction phase, the steel truss floor deck 3 can be directly laid onto the beams according to the construction load, and concrete can be poured after simple reinforcement work. The top lap plate 21 is connected to the galvanized profiled steel sheet 31 by nails, which is simple to connect and can be disassembled, and the disassembly process is also convenient.

[0042] In some possible implementations, the lap joint 2 includes a side plate 24 connected to the edge of the top lap plate 21 facing away from the connecting plate 23. The side plate 24 extends towards the bottom lap plate 22, and there is a gap between the side plate 24 and the bottom lap plate 22. The side plate 24 is spaced apart from the connecting plate 23, and the side of the side plate 24 facing away from the top lap plate 21 is spaced apart from the bottom lap plate 22. The top lap plate 21, bottom lap plate 22, connecting plate 23, and side plate 24 enclose an open cavity. This cavity not only does not affect the connection operation between the lap joint 2 and the aluminum alloy beam formwork assembly and the steel truss floor deck 3, but also protects the nails. In some possible implementations, the prefabricated construction structure combining floor decking and aluminum formwork includes aluminum formwork joists 5 and supporting uprights 6. At least some of the aluminum formwork joists 5 are located between adjacent aluminum alloy beam formwork assemblies and at the bottom of the steel truss floor decking 3, with each of the supporting uprights 6 supported at the bottom of the aluminum formwork joists 5. The spacing between adjacent steel truss floor decking slabs 3 is relatively large. Adding aluminum formwork joists 5 and supporting uprights 6 in the mid-span between adjacent steel truss floor decking slabs 3 combines the advantages of fast floor decking installation, less rebar binding, fewer support systems, and faster formwork removal, significantly improving the structural construction speed.

[0043] In some possible implementations, the aluminum formwork keel 5 includes a first-direction aluminum formwork keel 5 parallel to the steel truss floor deck 3 and a second-direction aluminum formwork keel 5 perpendicular to the steel truss floor deck 3. There is a gap between adjacent lap joints 2, and the end of the second-direction aluminum formwork keel 5 is inserted into the gap between adjacent lap joints 2.

[0044] In some possible implementations, the prefabricated construction structure of the floor decking combined with aluminum formwork includes multiple connecting rods 7, and each of the supporting columns 6 is connected by the multiple connecting rods 7 to form an integral structure. The connecting rods 7 connect adjacent supporting columns, enabling the supporting columns to be stably supported and also extending the height that the supporting columns can support.

[0045] The preferred embodiments disclosed above are merely illustrative of this application. The preferred embodiments do not exhaustively describe modifications and variations. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to better understand and utilize this application.
