[0019] See Figure 1 As shown, this application proposes an adjustable concrete formwork support device, which further includes: two arc-shaped support plates 8; connecting end plates 1, with connecting end plates 1 provided at both ends of the arc-shaped support plates 8; connecting side plates 6, with connecting side plates 6 provided on both sides of the arc-shaped support plates 8; and two arc-shaped steel modules 2, with the two arc-shaped steel modules 2 respectively provided on the two arc-shaped support plates 8.
[0020] Two connecting end plates 1 are welded to the outer wall of the arc-shaped support plate 8. The upper end face of the upper connecting end plate 1 is flush with the upper end face of the arc-shaped support plate 8, and the lower end face of the lower connecting end plate 1 is flush with the lower end face of the arc-shaped support plate 8. The two connecting end plates 1 are used to fix the arc-shaped support plate 8 to the external structure, ensuring the stability of the arc-shaped support plate 8. Multiple first connecting holes 9 are provided on the connecting end plates 1 at intervals. The connecting end plates 1 are connected to the external structure through the first connecting holes 9 and bolts, so that the arc-shaped support plate 8 is firmly fixed to the external structure.
[0021] Two connecting side plates 6 are welded to both sides of the arc-shaped support plate 8, and the sides of the connecting side plates 6 are flush with the vertical cross-section of the arc-shaped support plate 8. The two connecting side plates 6 are used to connect the two arc-shaped support plates 8, which together form the forming space of the circular large-volume concrete foundation. The connecting side plates 6 are provided with second connecting holes 5, and the connection of the two arc-shaped support plates 8 is achieved through the second connecting holes 5 and bolts.
[0022] Among them, the two arc-shaped steel modules 2 are the core structure of an adjustable concrete template support device. In actual use, the arc-shaped steel modules 2 with the corresponding inner diameter can be selected according to the circular large-volume concrete foundation, and the arc-shaped steel modules 2 can be detachably installed on the arc-shaped support plate 8 to form the corresponding circular large-volume concrete foundation support template. Concrete is poured on the support template, and after vibration, molding and curing, a circular large-volume concrete foundation is formed.
[0023] In this embodiment, a hollow groove can be provided on the arc-shaped steel module 2. The hollow groove helps to reduce the weight of the arc-shaped steel module 2 and facilitates the assembly of a concrete adjustable formwork support device.
[0024] Specifically, the connecting end plate 1 is used to fix the arc-shaped support plate 8 to the external structure, and the connecting side plate 6 is used to connect the two arc-shaped support plates 8. The two arc-shaped support plates 8 enclose the forming space of the circular large-volume concrete foundation. An arc-shaped steel module 2 with a corresponding inner diameter is selected according to the circular large-volume concrete foundation, and the arc-shaped steel module 2 is detachably installed onto the arc-shaped support plate 8 to form the corresponding circular large-volume concrete foundation support template. Concrete is poured into the support template, and after vibration, forming, and curing, the circular large-volume concrete foundation is formed.
[0025] Among them, the arc-shaped support plate 8, the connecting end plate 1, the connecting side plate 6, and the arc-shaped steel module 2 are all made of stainless steel 304. Stainless steel 304 has good corrosion resistance and excellent mechanical properties, which is conducive to an adjustable concrete formwork support device adapting to diverse and harsh construction environments.
[0026] During the pouring process, a release agent needs to be sprayed onto the inner wall surface of the curved steel module 2. Due to the non-absorbent nature of the curved steel module 2, this helps improve the surface quality of the large-volume circular concrete foundation.
[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the system further includes: multiple dovetail blind slots 81, spaced apart on the inner wall surface of the arc-shaped support plate 8; and multiple dovetail protrusions 21, disposed on the outer wall surface of the arc-shaped steel module 2, the protrusions 21 being adapted to the dovetail blind slots 81. When connecting the arc-shaped steel module 2 and the arc-shaped support plate 8, a stable connection is achieved by inserting the dovetail protrusions 21 on the outside of the arc-shaped steel module 2 into the corresponding dovetail blind slots 81 of the arc-shaped support plate 8. Through the cooperation of the dovetail blind slots 81 and the dovetail protrusions 21, the arc-shaped steel module 2 and the arc-shaped support plate 8 are made coaxial, and since the dovetail blind slots 81 are blind slots, the bottom of the dovetail protrusions 21 abuts against the bottom of the dovetail blind slots 81, thus limiting the vertical position of the arc-shaped steel module 2.
[0028] In this embodiment, the maximum width of the dovetail blind groove 81 can be selected according to actual needs. Preferably, the maximum width of the dovetail blind groove 81 is 6cm to 12cm to ensure that the connection strength between the arc-shaped support plate 8 and the arc-shaped steel module 2 meets the design requirements.
[0029] See Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the system further includes: a vertical protrusion 61 disposed on the connecting side plate 6 of one arc-shaped support plate 8; and a vertical groove 62 disposed on the connecting side plate 6 of another arc-shaped support plate 8, the groove adapting to the vertical protrusion 61. During the assembly of the two arc-shaped support plates 8, the vertical protrusion 61 is inserted into the vertical groove 62, facilitating quick positioning of the two arc-shaped support plates 8 before tightening the bolts.
[0030] In this embodiment, the vertical protrusion 61 is provided with a rounded chamfer. The rounded chamfer on the vertical protrusion 61 can not only reduce stress concentration, but also make it easier for the vertical protrusion 61 to be inserted into the vertical groove 62.
[0031] See Figure 5 and Figure 6 As shown, in some embodiments, it further includes: an arc-shaped protrusion 11, which is provided on the connecting end plate 1 at the bottom of the arc-shaped support plate 8. The arc-shaped protrusion 11 is adapted to the arc-shaped groove on the external structure and is used for preliminary positioning of the arc-shaped support plate 8, reducing the installation difficulty of the arc-shaped support plate 8.
[0032] See Figure 1 As shown, in some embodiments, it further includes: a lifting hole 7, which is provided on the arc-shaped steel module 2. The lifting hole 7 is used to screw on the lifting rod, and the crane connects to the lifting rod to realize the assembly and disassembly of the arc-shaped steel module 2.
[0033] See Figure 1 As shown, in some embodiments, the system further includes: multiple vertical reinforcing ribs 3, which are spaced circumferentially on the outer side of the arc-shaped support plate 8; and multiple circumferential reinforcing ribs 4, which are spaced vertically on the vertical reinforcing ribs 3. The vertical reinforcing ribs 3 and the circumferential reinforcing ribs 4 are used to strengthen the arc-shaped support plate 8.
[0034] The above description is only a part or preferred embodiment of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
