Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to an adjustable formwork support device for large-span curved irregular fair-faced concrete. Background Technology

[0002] Fair-faced concrete is widely used in modern buildings due to its unique decorative effect and environmental friendliness. In recent years, with the increasing complexity of building shapes, especially the emergence of large-span curved and irregular fair-faced concrete structures, higher requirements have been put forward for construction technology.

[0003] Currently, for the construction of large-span curved irregular fair-faced concrete, the structure and formwork system are usually modeled, and the formwork and keel are designed and optimized. However, the traditional formwork support system is difficult to adapt accurately when facing complex curved shapes, resulting in insufficient construction precision. Due to the insufficient stability of the formwork support system, cracks, air bubbles or unevenness are prone to occur during the concrete pouring process, thus affecting the final decorative effect.

[0004] Therefore, this utility model provides an adjustable formwork support device for large-span curved irregular fair-faced concrete. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an adjustable formwork support device for large-span curved irregular fair-faced concrete.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable formwork support device for large-span curved irregular fair-faced concrete, comprising a concrete slab and a base, wherein a locking component is provided on one side of the concrete slab.

[0007] A support assembly includes a bottom support block, a positioning rod fixedly connected to the top of the bottom support block, an adjusting rod inside the positioning rod, a threaded groove on the outer side of the adjusting rod, a top adjusting column at the top of the adjusting rod, and a top support block fixedly connected to one side of the top adjusting column.

[0008] In a preferred embodiment, the engaging assembly includes a slot at the top of the base, a top sliding groove at the top outer side of the concrete slab, and an adjusting groove at the bottom outer side of the concrete slab.

[0009] In a preferred embodiment, a handle is fixedly connected to the outer side of the adjusting rod.

[0010] In a preferred embodiment, the outer side of the bottom support block is slidably connected to a slot on the base.

[0011] In a preferred embodiment, the outer side of the top support block is slidably connected to a top groove on the concrete slab.

[0012] In a preferred embodiment, the outer side of the top support block is slidably connected to a top groove on the concrete slab.

[0013] In a preferred embodiment, the bottom end of the concrete slab is fixedly connected to a slot on the base.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This invention achieves fine-tuning of height through the threaded engagement of the adjusting rod and nut. The bottom slot and the top slide groove form a linked three-dimensional adjustable grid, and the sleeve structure of the positioning rod and the adjusting rod constitutes a truss-type rigid support. This design enables dynamic adjustment of the curvature of the curved surface, ensuring that the device can fit tightly and seamlessly with the concrete surface. In addition, the combination of a dual adjustment mechanism of coarse adjustment of the slide groove and fine adjustment of the thread significantly improves the flexibility and accuracy of construction positioning, significantly reduces the risk of formwork deformation during large-span construction, and effectively avoids the generation of defects such as surface bubbles and cracks caused by formwork deformation, thereby improving the overall construction quality.

The locking component 2 includes a locking groove 21 opened at the top of the base 4, a top sliding groove 22 opened at the top of the outer side of the concrete slab 1, and an adjustment groove 23 opened at the bottom of the outer side of the concrete slab 1.

[0028] Concrete slab 1, as the core load-bearing component of the entire formwork support device, directly contacts and supports the concrete, ensuring that the concrete maintains a stable shape during pouring and curing. Base 4, as an important part of the support structure, works in conjunction with concrete slab 1 to provide necessary support and fixation, enhancing the overall structural stability. The slot 21 is carefully designed and located at the top of concrete slab 1 to engage with the bottom of base 4. This design achieves fixation and support between concrete slab 1 and base 4. Furthermore, a top sliding groove 22 is also located on the outer top of concrete slab 1, cooperating with related components to provide sliding and adjustment functions, allowing concrete slab 1 to flexibly slide and adjust during construction to adapt to changes in different curved surfaces. Finally, an adjustment groove 23 is located at the outer bottom of concrete slab 1, allowing for fine-tuning of the concrete slab 1 in the height direction, ensuring a tight fit between the formwork and the concrete surface.

[0029] like Figure 1 - Figure 4As shown, the support assembly 3 includes a bottom support block 31, the outer side of which is slidably connected to a slot 21 on the base 4, the bottom end of the concrete slab 1 is fixedly connected to the slot 21 on the base 4, a positioning rod 32 is fixedly connected to the top end of the bottom support block 31, an adjusting rod 33 is provided inside the positioning rod 32, a threaded groove 34 is provided on the outer side of the adjusting rod 33, a top adjusting column 35 is provided at the top end of the adjusting rod 33, a top support block 36 is fixedly connected to one side of the top adjusting column 35, the outer side of the top support block 36 is slidably connected to a top groove 22 on the concrete slab 1, and a handle 37 is fixedly connected to the outer side of the adjusting rod 33.

[0030] The bottom support block 31 is the basic part of the support assembly 3. It is slidably connected to the slot 21 on the base 4 to stably support the entire device and ensure the stability of the construction process. The sliding connection design of the bottom support block 31 allows it to slide within the slot 21 for easy position adjustment. The positioning rod 32 is fixedly connected to the top of the bottom support block 31 to provide vertical support and positioning. The adjusting rod 33 allows for fine adjustment in the height direction to ensure a tight fit between the template and the concrete surface and to adapt to construction needs at different heights. The threaded groove 34 is opened on the outside of the adjusting rod 33 for use with the nut to fix and adjust the height and ensure construction accuracy. The top adjusting column 35 is set at the top of the adjusting rod 33 to provide top support, ensure the stability of the template, and adapt to complex construction environments. The top support block 36 is fixedly connected to one side of the top adjusting column 35 and is slidably connected to the top groove 22 on the concrete slab 1 to provide stable top support, ensure the stability of the template, and facilitate position adjustment. The handle 37 is designed to facilitate height adjustment by construction personnel and improve construction efficiency.

[0031] like Figure 1 - Figure 4 As shown:

[0032] In use: First, the bottom support block 31 slides in the slot 21 on the base 4 and is fixed after being adjusted to a suitable position, providing stable bottom support for the entire device. Then, the positioning rod 32 is fixedly connected to the top of the bottom support block 31, providing vertical support and positioning functions, which can drive the adjusting rod 33 to move up and down inside the positioning rod 32. Through the cooperation of the threaded groove 34 and the nut, the height can be precisely adjusted, thereby driving the top adjusting column 35 and the top support block 36 to slide in the top sliding groove 22 on the concrete slab 1, adapting to the changes in the curved surface and providing stable top support. At the same time, the handle 37 makes it convenient for construction personnel to operate the adjusting rod 33, improving construction efficiency. During construction, the bottom end of the concrete slab 1 is fixedly connected to the slot 21 on the base 4, ensuring a firm connection between the concrete slab 1 and the base 4. The top sliding groove 22 and the adjusting groove 23 cooperate with the top support block 36 and the adjusting rod 33 respectively, so that the concrete slab 1 can be slidably adjusted and finely adjusted in height during construction, adapting to complex curved shapes and ensuring a tight fit between the template and the concrete surface.
