Description

Technical Field

[0001] The present application relates to the field of formwork support, and in particular to a high-rise, large-span, cast-in-place floor slab formwork support platform. Background Art

[0002] With rapid economic development and accelerated urbanization, modern architectural design is becoming more diverse and complex. Iconic buildings, in particular, often feature unique designs. For example, large-span cast-in-place floor structures often have a strong visual impact, rich in creativity and unique characteristics.

[0003] At present, when pouring large-span cast-in-place floor slabs, formwork supports need to be set up underneath, and concrete pouring formwork is set up on the formwork supports to ensure the stability of the pouring formwork, thereby improving the pouring quality of the cast-in-place floor slab platform.

[0004] Formwork support structures typically utilize steel or wooden beams assembled into formwork brackets, which are then supported by a full-height scaffolding constructed using steel or wooden poles. This bracket is then used in conjunction with steel formwork for concrete construction. For cast-in-place formwork on high-rise, long-span platforms, cantilevered I-beams are typically installed, with a cantilevered platform constructed from these cantilevered I-beams, which are then used as the foundation for the formwork support.

[0005] Although the method of using cantilevered I-beams as the foundation to set up a cantilevered platform can reduce the ground floor space occupation and improve the utilization rate of the construction site to a certain extent, further setting up formwork supports on the cantilevered platform still faces challenges such as inconvenient operation and insufficient safety.

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The high-rise, large-span, cast-in-place floor formwork support platform provided in the embodiment of the present application includes a basic support frame 1, a cantilever support frame 2, a lifting device 3, and a formwork bracket 4. The basic support frame 1 is arranged inside the building floor and is connected to the structural beams and structural columns of the building to ensure sufficient stability. The cantilever support frame 2 is located on the horizontal side of the basic support frame 1 and is integrally arranged with the basic support frame 1, and the cantilever support frame 2 is arranged on the outside of the building in the form of a cantilever structure. The lifting device 3 and the formwork bracket 4 are both arranged on the cantilever support frame 2, and the lifting device 3 drives the formwork bracket 4 to rise and fall, thereby adjusting the height of the formwork bracket 4. Construction personnel can set up concrete pouring formwork on the formwork bracket 4 and complete the pouring of large-span concrete cast-in-place floor slabs.

[0035] Specifically, the foundation support frame 1 includes multiple columns and several horizontal beams, all made of section steel, providing sufficient strength, rigidity, and load-bearing capacity. The columns and horizontal beams are securely connected by welding or bolts. Furthermore, the foundation support frame 1 includes several reinforcing rods, which can be square tubes or mesh structures and are welded between the columns and horizontal beams to enhance the stability of the overall structure. The foundation support frame 1 is also equipped with a hydraulic jacking cylinder 11, which can abut against the beams on the floor where the foundation support frame 1 is located, thereby ensuring sufficient stability.

[0036] The horizontal beams on the basic support frame 1 extend to form the horizontal beams of the cantilever support frame 2. The cantilever support frame 2 also has a plurality of columns and reinforcing rods to ensure that it has sufficient bearing capacity.

[0037] The lifting device 3 also adopts a scissor lift or a mast lift, and its material can be selected from high-strength lightweight materials such as aluminum alloy. The template bracket 4 is also processed from lightweight materials such as aluminum alloy to reduce the overall weight of the template support platform while ensuring the bearing capacity.

[0038] Furthermore, the template bracket 4 includes a main bracket 41 and an extension bracket 42. An upper receiving groove 411 is provided on the top of the main bracket 41, and a horizontal slide rail is provided in the receiving groove 411. The extension bracket 42 is composed of an extension frame 421 and a support plate 422. The extension frame 421 is provided in the receiving groove 411, and a connecting sleeve is provided thereon, and the connecting sleeve is sleeved on the horizontal slide rail and slidably connected to the horizontal slide rail. In this way, the extension frame 421 can be moved and extended to one side of the main bracket 41 in the horizontal direction. At the same time, the connection between the connecting sleeve and the slide rail can vertically limit the extension frame 421 to ensure the stability of the extension frame 421. The support plate 422 can be assembled on the upper part of the main bracket 41, thereby increasing the supporting area of ​​the template bracket 4 to facilitate the erection of the template.

[0039] The support plate 422 is made of 12mm thick steel plate with anti-slip ribs on the surface and reinforcing ribs on the edges to increase the load-bearing capacity of the support plate 422. The support plate 422 has a snap-fitting portion at the edge, which can be completed by a hook or a snap-fit ​​structure, thereby achieving a reliable connection between the support plate 422 and the main bracket 41, and between two adjacent support plates 422.

[0040] Furthermore, the extension bracket 421 and the main bracket 41 are connected via a locking mechanism 5. The locking mechanism 5 comprises a locking pin and a locking sleeve. The locking pin is slidably mounted on the main bracket 41, while the locking sleeve is mounted on the extension bracket 421 and engages with the locking pin. The locking pin is vertically mounted and has a return spring mounted thereon. The return spring is connected to the main bracket 41.

[0041] The locking mechanism 5 also includes a pedal 51, which is fixedly connected to the locking pin and extends to the upper side of the main bracket 41. The pedal 51 can be used to easily press the locking pin down, thereby pulling the locking pin out of the lock sleeve for quick unlocking. The return spring then inserts the locking pin back into the lock sleeve to lock the lock.

[0042] The locking mechanism 5 is located at the end of the receiving slot 411 to ensure that the extension frame 421 can be connected to the main bracket 41 through the locking mechanism 5 when it is located in the receiving slot 411 and on one side of the main bracket 41 to ensure sufficient stability.

[0043] In order to further increase the stability of the extended bracket 42, the embodiment of the present application also adds a fixing rod. When the extended bracket is unfolded, the two ends of the fixing rod are fixedly connected to the extension frame 421 and the cantilever support frame 2 respectively, thereby reinforcing the extension frame 421 to improve the load-bearing performance.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
