Description

Technical Field

[0001] This utility model relates to the field of construction, and in particular to an adjustable cast-in-place floor slab formwork support frame. Background Technology

[0002] Architecture is a broad field that involves the design, construction, and maintenance of various structures, including residential, commercial, and infrastructure buildings.

[0003] When pouring concrete for the wall, an external support frame must first be erected. Then, a formwork is erected inside the external support frame to form a mold cavity, into which concrete can then be poured. The external support frame mainly consists of uprights, diagonal braces, and horizontal braces. The uprights form the foundation, and the horizontal and diagonal braces are fixed to the uprights using clips.

[0004] However, the following defects and shortcomings still exist in the application implementation process:

[0005] The poles need to be adjusted to match the height of the building, including short-distance fine-tuning and long-distance large-scale adjustments. The existing pole assembly (basic poles and assembled poles) is only connected by a snap-fit ​​structure. The assembled poles can be adjusted in length by loosening the snaps. As the main structure of the building rises, the assembled poles need to be fine-tuned. Since they are only fixed by snap-fit ​​connections, the snaps need to be released from the assembled poles each time an adjustment is made. This results in a high frequency of disassembly and assembly. At this time, the assembled poles need to be manually supported to achieve stability, which also poses certain safety hazards.

[0006] Therefore, it is necessary to provide a new adjustable cast-in-place floor slab formwork support frame to solve the above-mentioned technical problems. Utility Model Content

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 5 This utility model provides an adjustable cast-in-place slab formwork support frame, which includes a first upright 1 and a second upright 11, fixed together by a first clamp 2, and further includes:

[0030] Adjustable auxiliary support component 3 is installed on the first upright 1 and fixed to the second upright 11, and can drive the second upright 11 to move axially.

[0031] The auxiliary positioning component 4 is installed on the second upright 11 and is also movably connected to the first upright 1.

[0032] It should be noted that in this device, the first upright 1 and the second upright 11 are fixed together by the first clamp 2 to form a complete upright structure.

[0033] The adjustable auxiliary support component 3 is fixed to both the first upright 1 and the second upright 11. It can drive the second upright 11 to move in the axial direction to adjust its extension length. In the process of adjusting the second upright 11, it is necessary to contact the first locking head 2 to restrict the second upright 11. At this time, the adjustable auxiliary support component 3 can support the second upright 11. Therefore, no manual support is required, and the adjustment process will be simpler and safer.

[0034] The auxiliary positioning component 4 can further reinforce the assembly connection between the first upright 1 and the second upright 11, and is also used to limit the second upright 11.

[0035] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The adjustable auxiliary support assembly 3 includes a second clamp 31, which is fixed to the first upright 1. A positioning foot plate 32 is bolted to one side of the second clamp 31. A threaded rod 33 is rotatably connected to the positioning foot plate 32 along the axis of the first upright 1. A transmission cylinder 36 is threadedly connected to the outside of the threaded rod 33. A positioning ring frame 37 is welded and fixed to the outer circumference of the transmission cylinder 36. The transmission cylinder 36 is located inside the second upright 11 and is concentric with it. The positioning ring frame 37 is welded and fixed to the inner wall of the second upright 11.

[0036] Meanwhile, a concentrically arranged extension rod 34 is welded and fixed to one end of the threaded rod 33, and a hexagonal block 35 is welded and fixed to the extension rod 34.

[0037] It should be noted that when adjusting the second upright 11 using the adjustable auxiliary support assembly 3, the hexagonal block 35 is clamped and fixed by tools such as a wrench, and then the extension rod 34 is rotated, which in turn drives the threaded rod 33 to rotate. The threaded rod 33 is threadedly connected to the transmission cylinder 36, which can drive the transmission cylinder 36 to move along its axial direction. The transmission cylinder 36 is located inside the second upright 11 and is also fixed to it by the positioning ring frame 37, which can drive the second upright 11 to move. After the adjustment is completed, the first clamp 2 locks the second upright 11 again.

[0038] In the embodiments of this utility model, please refer to Figure 3 and Figure 5 The auxiliary positioning component 4 includes a positioning ring seat 41. A third locking head 42 is provided on the outer circumference of the positioning ring seat 41. The third locking head 42 is fixed on the second upright 11, while the first upright 1 passes through the positioning ring seat 41 concentrically and does not contact it.

[0039] Multiple ring-shaped balls 43 are also embedded in the inner circumference of the positioning ring seat 41, and the balls 43 roll on the outer circumference of the first upright 1.

[0040] It should be noted that in the auxiliary positioning component 4, the third locking head 42 is fixed on the second upright 11. When the second upright 11 moves, the entire auxiliary positioning component 4 also moves. The positioning ring seat 41 is fitted onto the first upright 1. It has a ball bearing 43 inside that can contact the first upright 1. The ball bearing 43 can roll on the first upright 1 and will not affect the movement of the second upright 11. At the same time, it can increase the assembly stability between the first upright 1 and the second upright 11.

[0041] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0042] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
