Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a prefabricated building aluminum formwork. Background Technology

[0002] In the construction of prefabricated buildings, aluminum formwork has become a commonly used formwork material due to its advantages such as high strength, light weight, and high reusability. However, existing prefabricated building aluminum formwork still has some problems in actual use. The existing aluminum formwork is difficult to adjust in terms of support height and angle, making it difficult to adapt to the construction needs of buildings with different heights and structures, thus reducing the versatility of the formwork. In addition, the support structure of some aluminum formwork is not stable enough, and it is easy to tilt or even collapse due to uneven stress during concrete pouring and other construction processes, which not only affects the construction progress but also poses a significant safety hazard. Utility Model Content

[0004] This utility model provides the following technical solution: It includes a beam template, with an installation plate mounted on the bottom end of the beam template. A transverse sliding plate is slidably connected to the inner wall of the installation plate. A positioning plate is provided below the transverse sliding plate. Hinges are hinged to both sides of the transverse sliding plate and the positioning plate. The hinges are hinged together by connecting blocks. A connecting hole is provided on the hinges and the connecting blocks. Corresponding support holes are provided on the transverse sliding plate and the positioning plate. A template support rod is provided below the support hole. A connecting rod is threaded onto the template support rod. A sliding plate is installed on the outer wall of the template support rod. A plug matching the connecting hole is installed at the top of the sliding plate.

[0017] Please see Figures 1-4 The present invention provides the following technical solution: a beam template 1, an installation plate 2 installed at the bottom of the beam template 1, a transverse plate 21 slidably connected to the inner wall of the installation plate 2, a positioning plate 22 provided below the transverse plate 21, hinge rods 23 hinged to both sides of the transverse plate 21 and the positioning plate 22, the hinge rods 23 being hinged to each other by a connecting block 24, the hinge rods 23 and the connecting block 24 having interconnected docking holes 241, the transverse plate 21 and the positioning plate 22 having corresponding support holes 25, a template support rod 3 provided below the support hole 25, a docking rod 31 threadedly connected to the template support rod 3, a sliding plate 32 installed on the outer wall of the template support rod 3, and an insert rod 33 matching the docking hole 241 installed at the top of the sliding plate 32.

[0018] In this implementation plan: Beam formwork 1 is used in building construction to form the pouring form for building beams, allowing concrete to be poured and then molded to form the beams. During the erection of beam formwork 1, to ensure its stability, formwork support rods 3 support the bottom of the formwork 1. The threaded connecting rods 31 on the formwork support rods 3 can be rotated to adjust their length, thus supporting the bottom of the beam formwork 1. When the formwork 1 is supported and reinforced by the formwork support rods 3 and connecting rods 31, the mounting plate 2 supports the bottom of the beam formwork 1. At this time, the transverse plate 21 slides between the mounting plates 2, and can be adjusted to the position where the template support rod 3 needs to support the bottom end of the beam template 1. At this time, the positioning plate 22 set below the transverse plate 21 can make way for the top of the connecting rod 31 through the connected support holes 25, so that the top of the connecting rod 31 can pass through the support holes 25 on the positioning plate 22 and the transverse plate 21 and be supported at the bottom end of the beam template 1. The hinge rods 23 installed on the outer walls of the transverse plate 21 and the positioning plate 22 are hinged to both sides of the transverse plate 21 and the positioning plate 22, so that the hinge rods 23 can be hinged to adjust their relationship with the transverse plate 21. The angle between the positioning plate 21 and the positioning plate 22 can be adjusted so that the adjacent hinge rods 23 are connected by the connecting block 24. This allows the positioning plate 22 to fit against the bottom of the transverse plate 21 during the erection of the beam formwork 1. The transverse plate 21 and the positioning plate 22 can then be stored between the mounting plate 2, facilitating the installation of the beam formwork 1. When it is necessary to limit the position of the formwork support rod 3, the positioning plate 22, connected by the hinge rods 23 and the connecting block 24, can unfold the hinge rods 23 and the connecting block 24 into a vertical position, allowing the connecting rod 31 to be limited within the transverse plate 21 and the positioning plate 22. Between the plates 22, the sliding plate 32 on the template support rod 3 can push the insertion rod 33, so that the insertion rod 33 can be inserted into the connecting hole 241 opened on the hinge rod 23 and the connecting block 24. This allows the insertion rod 33 to limit the hinge rod 23 and the connecting block 24, keeping them vertical. This allows the transverse plate 21 and the positioning plate 22 to maintain a vertical correspondence. This makes it easy to adjust the template support rod 3 and the connecting rod 31 to the bottom of the beam template 1 to a state of vertical support for the beam template 1. This ensures the stable support of the template support rod 3 and the connecting rod 31 for the beam template 1 and avoids tilting, which would affect the stability of the support for the beam template 1.

[0019] Limiting blocks 212 are installed at the connection between the mounting plate 2 and the transverse plate 21. Limiting grooves 211 matching the limiting blocks 212 are opened at both ends of the transverse plate 21. The limiting blocks 212 installed at the connection between the mounting plate 2 and the transverse plate 21 can connect and limit the limiting grooves 211, so that the transverse plate 21 can slide steadily between the mounting plates 2, ensuring that it slides horizontally below the beam formwork 1 and does not separate, so as to connect with the connecting rod 31 and vertically position the connecting rod 31.

[0020] The transverse plate 21 is perpendicular to the positioning plate 22, and the docking hole 241 is slidably connected to the insertion rod 33. The transverse plate 21 and the positioning plate 22 are perpendicular to each other, so that the transverse plate 21 and the positioning plate 22 can support the top of the insertion rod 33, so that the insertion rod 33 is vertically supported below the beam template 1. The docking hole 241 is slidably connected to the insertion rod 33, so that the insertion rod 33 can be supported and limited in the docking hole 241, so that the hinge rod 23 and the connecting block 24 can remain vertical.

[0021] A limiting plate 321 is installed at the top of the template support rod 3, and the insertion rod 33 passes through the limiting plate 321. The insertion rod 33 is flush with the template support rod 3 and the connecting rod 31. The limiting plate 321 is installed at the top of the template support rod 3 so that when the sliding plate 32 moves the insertion rod 33, it can limit the insertion rod 33 and ensure that the insertion rod 33 can maintain a horizontal sliding relative to the template support rod 3, so that it is connected and supported in the connecting hole 241, and the connecting rod 31 is flush with the hinge rod 23 and the connecting block 24.

[0022] The transverse plate 21 has a clearance hole 27 that communicates with the support hole 25. A restraining ring 261 is slidably connected to the inner wall of the clearance hole 27. A locking post 221 that matches the restraining ring 261 is installed on the positioning plate 22. The clearance hole 27 is used to install the restraining ring 261 so that the locking post 221 installed on the positioning plate 22 can engage with the restraining ring 261. Due to the large friction between the restraining ring 261 and the positioning plate 22, the positioning plate 22 can be attached to the transverse plate 21 so that the positioning plate 22 is attached to the transverse plate 21 when the beam formwork 1 is erected.

[0023] A pressure plate 26 is slidably connected to the inner wall of the support hole 25. The pressure plate 26 is connected to the restraining ring 261 through a connecting plate 262. The pressure plate 26 slides on the inner wall of the support hole 25 and is connected to the restraining ring 261 through the connecting plate 262, so that the top of the docking rod 31 can support the pressure plate 26, so that it pushes the restraining ring 261 upward, so that it separates from the locking post 221, so that the positioning plate 22 can fall down and be positioned below the transverse plate 21.

[0024] The working principle and usage process of this utility model are as follows: Before constructing the building structure, according to construction requirements, rotate the connecting rod 31 on the template support rod 3 to adjust its length so that it initially matches the required support height of the beam template 1. Place the beam template 1 in the predetermined position and support it at the bottom end by the mounting plate 2. Slide the transverse plate 21 to adjust it to the position where the template support rod 3 needs to support the bottom end of the beam template 1. At this time, under the hinge action of the hinge rod 23 and the connecting block 24, the transverse plate 21 and the positioning plate 22 unfold the positioning plate 22 from the retracted state that is attached to the transverse plate 21, so that the hinge rod 23 and the connecting block 24 are vertical, preparing for subsequent support. Move the template support rod 3 and the connecting rod 31 to the corresponding position so that the top of the connecting rod 31 passes through the support hole 25 opened on the positioning plate 22 and the transverse plate 21 and supports the bottom end of the beam template 1. Push the sliding plate 32 on the template support rod 3 to drive the insertion rod 33 to pass through the opening on the hinge rod 23 and the connecting block 24. Within the interconnected docking hole 241, the hinge rod 23 and the connecting block 24 are limited to ensure that the transverse plate 21 and the positioning plate 22 are vertically aligned. At this time, the template support rod 3 and the docking rod 31 are in a stable state of vertical support for the beam template 1. The pressure plate 26 is supported at the top of the docking rod 31. The binding ring 261 is moved upward by the connecting plate 262, causing it to separate from the clamping column 221. At this time, the positioning plate 22 falls below the transverse plate 21 under the action of gravity, further strengthening the fixation of the docking rod 31, thus completing the installation and support work of the entire aluminum template. After the construction is completed, the above steps are reversed. First, the pressure plate 26 is pulled down to make the binding ring 261 engage with the clamping column 221. The positioning plate 22 is lifted to fit against the transverse plate 21. Then, the insertion rod 33 is pulled out from the docking hole 241. The docking rod 31 is rotated to shorten its length. The template support rod 3 and the docking rod 31 are moved out from under the beam template 1. Finally, the beam template 1 is disassembled. The whole process is simple and convenient and easy to reuse.
