Description

Technical Field

[0001] This utility model relates to the field of building formwork, and in particular to an assembled aluminum alloy formwork for floor deck trusses. Background Technology

[0002] Current building formwork systems mainly include wooden formwork, steel formwork, and plastic formwork. Wooden formwork is low in cost but has a limited number of uses and is prone to deformation and cracking; steel formwork has high strength but is heavy and difficult to handle and install; plastic formwork is lightweight but lacks rigidity and is prone to aging. Therefore, in recent years, aluminum alloy formwork has gradually been used due to its advantages such as being lightweight and high-strength, corrosion-resistant, and having a high number of uses.

[0003] For related technology, please refer to Chinese Patent No. CN117703056A, which discloses a high-strength alloy template, including a template unit. The template unit has two parallel vertical ribs fixedly installed in the vertical direction, and multiple horizontal ribs are equally spaced on the template unit. Multiple reinforcing plates are installed between the two parallel vertical ribs. Inner sealing plates are fixed around the template unit, and the ends of the inner sealing plates are bent and fitted at 180°.

[0004] Regarding the aforementioned technologies, existing aluminum alloy formwork systems are mostly designed as a single unit, which is inconvenient for transportation and storage, and has poor flexibility, making it difficult to adapt to complex and ever-changing construction needs. Utility Model Content

[0005] To improve the flexibility of using aluminum alloy formwork, this application provides modular aluminum alloy formwork for floor deck trusses.

[0006] This application provides a modular aluminum alloy formwork for floor deck trusses, employing the following technical solution:

[0007] Several template units are provided, and several connecting edges are fixed along the circumference of each template unit. All connecting edges are located on the same end face of the template unit, and several mounting holes are provided along the length of the connecting edges. When two adjacent template units are spliced ​​together, the mounting holes at the splicing point are connected in pairs.

[0008] The template connector is located between two adjacent template units. The connector passes through the two connecting edges sequentially along the mounting hole, pushing the two connecting edges to tighten and fit together, and keeping the two mounting holes in the same group coaxial.

[0009] Truss connectors are detachably connected to the side of the formwork unit away from the connection edge;

[0010] The floor deck truss is connected to the formwork unit via truss connectors;

[0011] A seal is located between two adjacent template units and is used to seal the gap between the two template units.

[0012] By adopting the above technical solution, when the formwork units are spliced ​​horizontally or vertically, they are pressed together by the connecting edges. At this time, the connecting parts lock and position the two adjacent connecting edges through the mounting holes, thus connecting the horizontally and vertically adjacent formwork units into a whole. The formwork units support and fix the floor deck truss through the truss connectors, which facilitates the support of the floor deck. The sealing parts cover the gaps between adjacent formwork units, which helps to improve the waterproof effect between adjacent formwork units and reduce the probability of grout penetration. The length and width of the formwork units can be adjusted as needed, and different formwork units can be spliced ​​together at will, which helps to improve the flexibility of the use of aluminum alloy formwork.

[0013] Optionally, the connector includes a positioning pin and a positioning plate. The two ends of the positioning pin along the axial direction are respectively set as a fixed end and a positioning end. The diameter of the positioning pin gradually decreases along the direction from the fixed end to the positioning end. The maximum diameter of the fixed end is greater than the diameter of the mounting hole, and the diameter of the positioning end is smaller than the diameter of the mounting hole. The positioning plate is located at the positioning end and passes through the positioning pin radially. Two vertically adjacent connecting plates are located between the positioning plate and the fixed end and contact the positioning plate and the fixed end respectively.

[0014] By adopting the above technical solution, when installing the positioning pin, the positioning end of the positioning pin first passes through the connecting plate along the mounting hole. When the outer surface of the fixed end contacts the inner wall of the mounting hole, the positioning plate passes through the positioning pin, so that the positioning plate and the fixed end cooperate to clamp and position the two connecting plates. The diameter of the positioning pin is gradually set, so it is suitable for mounting holes of different diameters. When the connecting plate deforms under long-term operation, the positioning effect can still be maintained.

[0015] Optionally, the truss connector includes a card seat, a connecting seat, and a concrete pad. The connecting seat is located on the side of the formwork unit away from the connecting edge and is detachably connected to the formwork unit by bolts. The concrete pad is located between the formwork unit and the connecting seat and is used to adjust the distance between the connecting seat and the formwork. The card seat is located on the side of the connecting seat away from the formwork unit, and both the connecting seat and the card seat have slots for accommodating and fixing the floor slab truss.

[0016] By adopting the above technical solution, the connecting seat supports and positions the card seat, and the card seat and connecting seat cooperate to fix the floor deck truss through the card slot. The thickness of the concrete pad can be adjusted according to actual needs, making it suitable for different installation conditions.

[0017] Optionally, it also includes: pipe embedded parts, which include a connecting frame and pipe clamps. The connecting frame is provided with a connecting part and is connected to the floor deck truss through the connecting part. The pipe clamps are connected to the side of the connecting frame away from the formwork unit and extend to the outside of the floor deck truss for fixing the pipes.

[0018] By adopting the above technical solution, the connecting frame is connected to the floor deck truss through the connecting part, which facilitates the adjustment of the position along the length of the floor deck truss. The pre-embedded pipe is locked and positioned by the pipe clamp, which helps to improve the convenience and accuracy of pipe pre-embedded installation.

[0019] Optionally, the template connector further includes a horizontal plate and several positioning bolts. A through groove for placing the horizontal plate is opened along the thickness direction of the connecting edge. When the horizontal plate is located in the through groove, it contacts the connecting edge. The template unit is fixed with a fixing block corresponding to the positioning bolt. A placement opening for the horizontal plate to pass through is left between the fixing block and the template unit. The positioning bolt passes through the fixing block and is threadedly connected to the fixing block. The positioning bolt abuts against the side of the horizontal plate away from the template unit.

[0020] By adopting the above technical solution, the connecting edge restricts the horizontal plate through the through groove. The horizontal plate is located in the placement opening when it is in working state. Under the support of the fixing block, when the positioning bolt is tightened, the positioning bolt pushes the horizontal plate to fit with the template unit, thereby aligning and positioning the two adjacent template units.

[0021] Optionally, the horizontal plate has mounting grooves that correspond one-to-one with the positioning bolts. When the positioning bolts are located in the mounting grooves and abut against the inner wall of the mounting grooves, the two adjacent connecting edges fit together.

[0022] By adopting the above technical solution, the horizontal plate limits the positioning bolts through the mounting groove, reducing the probability of relative slippage between the horizontal plate and the positioning bolts and improving the installation stability of the horizontal plate.

[0023] Optionally, a frustum column is fixed at one end of the positioning bolt near the horizontal plate. The diameter of the frustum column gradually decreases towards the template unit. The mounting groove is rectangular and perpendicular to the corresponding connecting edge between two adjacent template units. A guide block adapted to the frustum column is fixedly connected to the horizontal plate. The guide block is located on the side of the mounting groove away from the corresponding connecting edge. When the frustum block contacts the guide block, a thrust away from the connecting edge is applied to the guide block.

[0024] By adopting the above technical solution, when tightening the positioning bolt, the positioning bolt applies a pushing force to the guide block through the frustum. At this time, the guide block tends to move away from the corresponding connection edge, and the positioning bolt is subjected to the reaction force of the guide block. In turn, the fixing block pushes the two template units to fit together, further improving the connection tightness of the template units.

[0025] Optionally, the sealing element includes a sealing plate and a flexible plug. The flexible plug is fixed to one side of the sealing plate and is arranged along the length of the sealing plate. A placement groove is opened on the side of the template unit along the length direction. The placement groove is connected to the through groove. When two adjacent template units are spliced ​​together, the two placement grooves cooperate to form a receiving groove. When the sealing plate is located in the installation groove, the gap between the flexible plug and the two adjacent template units is directly opposite. A push block is fixed on the side of the sealing plate away from the flexible plug. The push block passes through the placement groove and extends into the through groove. The side of the horizontal plate away from the positioning bolt abuts against the push block.

[0026] By adopting the above technical solution, the template unit accommodates the sealing plate and the flexible blocking block through the receiving groove. When the positioning bolt pushes the horizontal plate to fit with the template unit, the horizontal plate applies a pushing force to the sealing plate through the push block, so that the sealing plate pushes the flexible blocking block to seal and block the gap between two adjacent template units.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The formwork units are detachable and assembleable, making transportation and storage convenient and saving space. The formwork units can be set to different sizes and shapes, and can be adjusted during use to suit different construction needs, offering high flexibility.

[0029] 2. Adjacent template units do not need to be fixed by welding when splicing, which makes installation and disassembly efficient, helps to shorten the construction period and reduce costs.

[0030] 3. Both the template units and connecting components can be reused, which is economical and environmentally friendly. Attached Figure Description

[0035] The present application will be further described in detail below with reference to all the accompanying drawings.

[0036] This application discloses an assembled aluminum alloy formwork for floor deck trusses. Example

[0037] Reference Figure 1 and Figure 2 This is an assembled aluminum alloy formwork for floor deck trusses, comprising multiple formwork units 1, which are spliced ​​together horizontally and vertically to form a formwork system. Each formwork unit 1 has a connecting edge 11 vertically fixed along its circumference, and all connecting edges 11 of the same formwork unit 1 are located on the same side. The side of the formwork unit 1 facing away from the connecting edge 11 is a plane.

[0038] All connecting edges 11 are provided with at least two mounting holes 12 along their length. For two adjacent and flush template units 1, the mounting holes 12 on the two connecting edges 11 that are close to each other are coaxial. A template connector is provided between two vertically adjacent template units 1. The template connector includes a positioning pin 21 and a positioning plate 22. The diameter of the positioning pin 21 gradually decreases along its length, and the end with the larger diameter of the positioning pin 21 is designated as the fixed end. A baffle is fixedly connected to the fixed end, and the maximum diameter of the fixed end is greater than the inner diameter of the mounting hole 12. The end with the smaller diameter of the positioning pin 21 is designated as the positioning end, and the diameter of the positioning end is smaller than the diameter of the mounting hole 12.

[0039] The positioning end has a radially open mounting opening for placing the positioning plate 22, and the width of the mounting opening is greater than the width of the positioning plate 22. Two coaxial and interconnected mounting holes 12 are set as a group. When splicing two vertically adjacent template units 1, the positioning end of the positioning pin 21 is passed through the two connecting edges 11 along the mounting hole 12 until the fixed end contacts the inner wall of one of the mounting holes 12.

[0040] The positioning plate 22 is passed through the mounting opening, at which point the two connecting edges 11 are located between the baffle and the positioning plate 22. The side of the positioning plate 22 away from the fixed end is designated as a guide surface, which gradually approaches the fixed end along the length of the positioning plate 22. The side of the positioning plate 22 near the connecting edge 11 is a flat surface, which abuts against and fits against the connecting edge 11. When the guide surface contacts the inner wall of the mounting opening away from the fixed end, and the positioning plate 22 is pushed along its length, under the limiting action of the connecting edge 11, the positioning plate 22 applies a pushing force to the positioning pin 21 through the guide surface, causing the baffle to tend to move closer to the positioning plate 22, which helps to improve the locking effect on the two connecting plates.

[0041] At least two sets of positioning pins 21 are provided between two adjacent connecting edges 11, and the two sets of positioning pins 21 on the same connecting edge 11 are set in opposite directions, thereby limiting the relative displacement of the two connecting edges 11 along the length direction, improving the installation stability of the connecting edges 11 and improving the installation accuracy of the template unit 1.

[0042] Furthermore, the template connector also includes a horizontal plate 23 and multiple positioning bolts 24. A through groove 111 is formed along the thickness direction at the connection point between the connecting edge 11 and the template unit 1. The through groove 111 is used to install the horizontal plate 23. When the horizontal plate 23 is located within the through groove 111, it has room to move closer to or further away from the template unit 1. The multiple positioning bolts 24 are divided into two groups, each corresponding to two adjacent template units 1. Each template unit 1 is fixed with a fixing block 14 corresponding to one of the positioning bolts 24. The fixing blocks 14 are located at both ends of the through groove 111 along its length, and a placement opening is provided near the template unit 1. When installing the horizontal plate 23, after aligning the horizontal plate 23 with the placement opening, moving the horizontal plate 23 laterally allows it to enter the corresponding through groove 111.

[0043] The positioning bolt 24 is threaded onto the side of the fixing block 14 away from the template unit 1, and the positioning bolt 24 is perpendicular to the template unit 1. When the positioning bolt 24 is tightened, it passes through the fixing block 14 and abuts against the horizontal plate 23, pushing the horizontal plate 23 to fit against the template unit 1. The end face of the horizontal plate 23 that contacts the template unit is flat. Under the pushing action of the positioning bolt 24, the horizontal plate 23 limits the two adjacent template units 1, so that the two template units 1 are in the same plane, thereby aligning the two adjacent template units 1.

[0044] Reference Figure 2 and Figure 3 A mounting groove 231 corresponding to the positioning bolt 24 is provided on the side of the horizontal plate 23 away from the template unit 1. The mounting groove 231 is rectangular and perpendicular to the connecting edge 11 at the corresponding position. A guide block 232 is fixed in the horizontal groove of the horizontal plate 23. The guide block 232 is located on the side of the mounting groove 231 away from the corresponding connecting edge 11. A frustum column 241 is fixedly connected to the end of the positioning bolt 24 near the horizontal plate 23. The diameter of the frustum column 241 gradually decreases in the direction away from the positioning bolt 24. The guide block 232 has an arc surface adapted to the frustum column 241.

[0045] After the horizontal plate 23 is installed in the appropriate position, the mounting groove 231 is aligned with the corresponding positioning bolt 24. Tightening the positioning bolt 24 then brings the frustum 241 into contact with the arc surface of the guide block 232. At this point, the frustum 241 applies a pushing force to the guide block 232, causing the guide block 232 to tend to move away from the connecting edge 11. The positioning bolt 24 receives a reaction force from the guide block 232, which in turn pushes the two template units 1 together through the fixing block 14.

[0046] Furthermore, the template unit 1 also includes a sealing element 6, which includes a sealing plate 61 and a flexible block 62. The flexible block 62 is made of a deformable material, such as rubber. The sealing plate 61 is adapted to the side length of the template unit 1, and the flexible block 62 is fixedly connected to one side of the sealing plate 61. A placement groove 15 is provided circumferentially along the length of the long side edge of the template unit 1. For two adjacent template units 1, the two adjacent placement grooves 15 are connected and form a receiving groove adapted to the sealing plate 61. The placement groove 15 communicates with the through groove 111, and the horizontal plate 23 is directly opposite the placement groove 15 in the installed state.

[0047] A push block 63 is fixedly connected to the side of the sealing plate 61 opposite to the flexible plug 62. Both the sealing plate 61 and the flexible plug 62 are located in the receiving groove, and the push block 63 passes through the placement groove 15 and extends into the through groove 111. At this time, the gap between the flexible plug 62 and the adjacent template unit 1 is directly opposite. The horizontal plate 23 contacts the push block 63 in the pressed state, and pushes the flexible plug 62 against the inner wall of the placement groove 15 through the sealing plate 61. At this time, the flexible plug 62 seals the gap between the adjacent template units 1, which helps to improve the sealing effect between the adjacent template units 1.

[0048] Reference Figure 1 and Figure 2 Furthermore, the formwork system also includes truss connectors 3 and floor deck trusses 4. The floor deck trusses 4 are used to support the building floor deck. The truss connectors 3 include a bracket 31, a connecting seat 32, and a concrete pad 33. The connecting seat 32 is located on the side of the formwork unit 1 away from the connecting edge 11. The formwork unit 1 for installing the connecting seat 32 is provided with mounting bolts 13 corresponding to the connecting seat 32. The bolts pass through the formwork unit 1 from the side of the formwork unit 1 where the connecting edge 11 is located and are threadedly connected to the connecting seat 32, thereby fixing the connecting seat 32.

[0049] The mounting bracket 31 is located on the side of the connecting bracket 32 ​​opposite to the formwork unit 1, and both the mounting bracket 31 and the connecting bracket 32 ​​are provided with mounting slots. When one side of the floor deck truss 4 is located in the corresponding mounting slot, the connecting bracket 32 ​​and the mounting bracket 31 cooperate to support and fix the floor deck truss 4. The concrete pad 33 is located between the connecting bracket 32 ​​and the formwork unit 1, and is used to adjust the distance between the connecting bracket 32 ​​and the formwork unit 1. The concrete pad 33 can be formed by post-pouring, and its thickness can be adjusted according to the required installation position of the connecting bracket 32, which is suitable for different installation conditions.

[0050] Furthermore, the template system also includes a pipe embedding component 5, which includes a connecting frame 51 and a pipe clamp 52. Firstly, the embedded pipe can be directly laid along the floor deck truss 4, and the floor deck truss 4 supports and positions the pipe. The connecting frame 51 has a connecting part, which includes a fixing frame 531 and a fixing bolt 532. The fixing frame 531 is fixedly connected to the connecting frame 51, and a fixing groove adapted to the floor deck truss 4 is opened between the connecting frame 51 and the fixing frame 531. One side of the floor deck truss 4 is located in the fixing groove and contacts the inner wall of the fixing groove. The fixing bolt 532 passes through the fixing frame 531 and abuts against the floor deck truss 4, thereby cooperating with the fixing frame 531 to clamp and position the floor deck truss 4, so that the connecting frame 51 is fixed on the floor deck truss 4.

[0051] The connecting frame 51 also includes an extension rod 54, which is slidably connected to the fixing frame 531 along the axial direction and extends to the outside of the floor deck truss 4. The fixing frame 531 is provided with clamping bolts for clamping the extension rod 54, and the pipe clamp 52 is installed on the side of the extension rod 54 away from the fixing frame 531. When the pipes laid along the floor deck truss 4 need to bend and extend away from the floor deck truss 4, the pipe clamp 52 supports and positions the pipes, thereby improving the pre-embedded stability of the pipes.

[0052] The connecting frame 51 is also provided with bolt mounting holes 12 on the side facing the template unit 1, and the bolt mounting holes 12 correspond one-to-one with the mounting bolts 13. When the template unit 1 is not equipped with the floor deck truss 4 and the corresponding truss connectors 3, the connecting frame 51 is fixed by the mounting bolts 13, which facilitates the support and fixation of the pipes in places without the floor deck truss 4, and facilitates the fixation of the pipes in different positions.

[0053] The implementation principle of the prefabricated aluminum alloy formwork for floor deck trusses in this application embodiment is as follows: Formwork unit 1 can be arbitrarily disassembled and assembled via formwork connectors, making transportation and storage convenient and saving space. During assembly, the alignment of adjacent formwork units 1 is achieved through the cooperation of positioning pins 21 and mounting holes 12, and the cooperation of horizontal plates 23 and connecting edges 11, thereby improving the installation accuracy of formwork unit 1. Formwork unit 1 supports and fixes the floor deck truss 4 via truss connectors 3, which are detachable and suitable for different working conditions. Embedded pipes are supported and fixed via pipe pre-embedded parts 5, improving the applicability of formwork unit 1. Formwork unit 1, formwork connectors, and truss connectors 3 are all detachable, facilitating reuse. The ease of disassembly and assembly helps shorten the construction period and reduce costs.

[0054] 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.
