Technical Field
[0001] The utility model belongs to the technical field of bridge construction, in particular to a convenient caisson template removal platform. Background Art
[0002] A caisson foundation is a type of deep foundation, also known as a caisson or caisson foundation. It involves excavating a deep well underground and then pouring concrete inside to form a foundation. Caisson foundations are commonly used in large-scale projects such as buildings, bridges, docks, and water conservancy projects to provide stable foundation support. Caisson construction involves using a pre-existing, well-shaped structure made of reinforced concrete on the ground as support for the foundation pit walls. Under the protection of the well walls, soil is excavated mechanically within the well, and the structure sinks into the ground under its own weight.
[0003] When the flip mold method is used in the caisson concrete pouring construction (the flip mold method is to divide the formwork of a section of concrete tower column into 2 to 3 sections. After the concrete is poured, the upper section of the formwork remains unchanged, and the lower formwork is removed and lifted to the top of the unremoved formwork using lifting equipment such as a tower crane, and connected to it as a whole for pouring concrete for the next construction section, and so on, it rises alternately from bottom to top until the designed construction height is reached), in addition to customizing two layers of formwork, it is also necessary to customize two layers of demoulding platforms, which greatly increases the construction cost.

[0015] Figure 3 This is a schematic diagram of the installation of a convenient caisson template removal platform. DETAILED DESCRIPTION
[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.
[0018] like Figure 1 、 Figure 2 As shown, the portable caisson template removal platform provided in this embodiment has an overall C-shaped structure, which comprises, from top to bottom, a fixed top frame 1, a back frame 2, and a bottom frame 3. The length of the bottom frame 3 is less than that of the top frame 1. In this embodiment, the length of the top frame is 1.85 meters, the length of the bottom frame is 1.45 meters, and the height of the back frame is 2.45 meters. The top frame 1 includes upper and lower horizontal channel steels 11, and a plurality of vertical channel steels 12 are arranged between the upper and lower horizontal channel steels 11. The first vertical channel steel can be detachably installed to the top of the upper and lower horizontal channel steels 11, and the other vertical channel steels are fixedly installed between the upper and lower horizontal channel steels 11. The space between the upper and lower horizontal channel steels and the first and second vertical channel steels forms a back rib installation area A.
[0019] As shown in the diagram, each side has four vertical channels. The spacing between the upper and lower horizontal channels is 225mm, and the spacing between the first and second vertical channels is 210mm. This creates a back-rib installation area A with dimensions of 225mm x 210mm. The first vertical channel is bolted to the top of the upper and lower horizontal channels, with two bolts at each locking position to enhance connection strength. The entire demolition platform is lightweight, with a total mass of 235kg.
[0020] Installation method of caisson template removal platform Figure 3 As shown, the demolition platform is marked as 100, the caisson construction platform is marked as 200, and the formwork back rib is marked as 300. The vertical guardrail of the caisson construction platform can be removed before installing the demolition platform. The front and rear tops of the top frame 1 are fixed with lifting lugs 7, and the demolition platform is lifted by the lifting lugs 7. Since the demolition platform is C-shaped as a whole, it can avoid the caisson construction platform. For safety reasons, a guardrail 4 is fixed between the base frame 3 and the lower part of the back frame 2, and a diagonal support 6 is also fixed between the left and right sides of the base frame 3 and the top of the back frame 2. In addition, the guardrail 4 has a rope hole 41 at the top corner position facing the caisson, and a steel wire rope 5 is connected between the rope holes of the guardrail 4 to play a protective role. The base frame 3 is paved with a patterned steel plate 31, and the back frame 2 is fixed with multiple running rods 21 along the height direction.
[0021] In addition, a horizontal steel 13 is fixed between the upper horizontal channel steels and between the lower horizontal channel steels, near the position of the second vertical channel steel, to strengthen the firmness of the top frame.
[0022] Lift the dismantling platform, place the first vertical channel steel on the back of the outer back rib of the formwork, insert the upper and lower horizontal channels into the back rib so that the back rib is located between the upper and lower horizontal channels, and finally lock the first vertical channel steel and the upper and lower horizontal channels. This way, the top frame of the dismantling platform can be fixed to the back rib of the formwork, and the workers can perform the formwork dismantling operation on the bottom frame. Of course, you can also first insert the front sections of the upper and lower horizontal channels into the back rib, then place the first vertical channel steel on the back of the outer back rib of the formwork and lock it with the upper and lower horizontal channels. In addition, the step rods on the back frame allow workers to move between the caisson construction platform and the bottom frame, which is also relatively convenient. Workers remove the formwork on the checkered steel plate of the bottom frame. This dismantling platform is compact and convenient, easy to move and operate, and greatly reduces construction costs.
[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
