DETAILED DESCRIPTION

[0041] The construction device 300 for pouring concrete chain-type string barrel 100 of bridge pier column of the present invention is applicable to the string barrel pouring construction of bridge pier column or pile foundation, wherein the chain-type string barrel 100 comprises a crossbeam 130, a support chain 120 and a conical cylinder 110, the crossbeam 130 is arranged on the top of the pier column formwork 200, at least two support chains 120 are provided, which are suspended on the crossbeam 130, and a plurality of conical cylinders 110 are provided, which are plugged and overlapped in sequence, and are suspended on the support chains 120 on both sides. Hooks are provided on both sides of the conical cylinder 110, and the hooks are fixedly connected to the conical cylinder 110, or the hooks are connected to the conical cylinder 110 by chains.

[0042] Reference Figures 2 - 5 The construction device 300 includes a platform support 310, a chain guide 330, a string guide 320 and a chain traction mechanism 340. The platform support 310 can be adjusted according to different construction purposes. For example, when constructing a pile foundation, the platform support 310 can be directly arranged on the ground; if it is to construct a bridge pier, the platform support 310 needs to be arranged on the template support 400 where the pier template 200 is installed. A hydraulic lifting component 350 can also be arranged to drive the platform support 310 to rise and fall to adjust the height of the platform support 310.

[0043] The chain guide rail 330 and the string cylinder guide rail 320 are both arranged on the platform bracket 310, and extend out of the body of the platform bracket 310 through the cantilever structure, which can ensure that the suspended conical cylinder 110 can be located in the inner cavity of the template.

[0044] Specifically, the design purpose of the string guide rail 320 is to enable the conical string to be suspended on the string guide rail 320, and the string guide rail 320 can guide the conical string suspended on the string guide rail 320 to slide to the horizontal section 331 of the chain guide 330 so as to be suspended on the support chain 120 on the horizontal section 331.

[0045] The string guide 320 is two guide rods arranged obliquely in this embodiment, and it can also be in other structural forms. One end of the guide rod is connected to the platform bracket 310 to form a cantilever structure. The operator can hang the conical cylinder 110 on the two guide rods. Since the guide rods are arranged obliquely, the conical cylinder 110 hanging on the guide rods can slide along the guide rods and finally slide out from the end of the guide rods.

[0046] Referring to Figure 6 , the guide rod has a first inclined section 321 and a second inclined section 322. The inclination angle of the first inclined section 321 is smaller than that of the second inclined section 322. The end of the first inclined section 321 is connected to the platform bracket 310. The purpose of adopting the two-section guide rod structure is that the inclination angle of the first inclined section 321 is small, and the sliding speed of the conical cylinder 110 is slow, avoiding sliding out of the guide rod due to too fast a speed; while the inclination angle of the second inclined section 322 is larger. In this embodiment, it is preferably that the included angle between the second inclined section 322 and the horizontal section 331 (introduced later) of the chain guide 330 or the horizontal plane is 80° - 65°. The larger included angle can make the conical cylinder 110 tend to be in a vertical sliding state, which is convenient for inserting the conical cylinder 110 below, but it cannot be in a vertical state, otherwise the conical cylinder 110 is likely to slide out of the guide rod. Therefore, the setting of the angle is an important factor for whether the conical cylinder 110 can smoothly enter the lower cylinder and whether it can be accurately hung on the support chain 120. At the same time, if the hook of the conical cylinder 110 is a fixed structure, the end of the second inclined section 322 can be arranged at a position far from the chain guide 330 to achieve smooth insertion into the support chain 120; if the hook adopted is a chain connection method, the end of the second inclined section 322 needs to be arranged as close as possible to the support chain 120 to avoid the hook not being accurately inserted when sliding down. Another advantage of adopting the chain connection method is that when the conical cylinder 110 is at the bending position of the chain guide 330 or during subsequent storage, the conical cylinder 110 can well adjust its posture to adapt to the required movement.

[0047] There are two chain guides 330, arranged side by side, and the middle spacing is equivalent to the spacing of the string guide 320. Since there is a spacing in the middle, one end of the chain guide 330 is connected to the platform bracket 310 to form a cantilever structure. During actual arrangement, a slide rail can be arranged at the bottom of the construction device 300 to realize the radial movement of the entire construction device 300 along the pier column. When moving, it can be inserted into the gaps between the steel bars of the steel reinforcement cage. Such a cantilever and spaced side-by-side configuration method is convenient for inserting into the steel bar gaps, which enables the platform bracket 310 to match the formwork bracket 400 in the height direction, eliminating the cumbersome work of additionally raising the platform bracket 310.

[0048] The chain guide rail 330 is designed with a cross-shaped cavity structure in the middle that can guide the chain, and the upper and lower surfaces are open. This enables the conical cylinder 110 that slides off the guide rod to ensure that the hooks on both sides can be inserted into the horizontal links of the supporting chain 120. To ensure that the conical cylinder 110 can be inserted into the horizontal link, the chain guide rail 330 includes a horizontal section 331 and a vertical section 333. The horizontal section 331 maintains the horizontal movement of the supporting chain 120, so that the hooks of the conical cylinder 110 can be accurately inserted. The arrangement of the vertical section 333 ensures that the conical cylinders 110 are finally vertically connected in series.

[0049] Since the stringer guide rail 320 is inclined, that is, the moving direction of the conical cylinder 110 is a sliding along an inclined trajectory in a vertical state. To ensure that the conical cylinder 110 can be smoothly inserted into the conical cylinder 110 below, the chain guide rail 330 further includes a return section 332. The return section 332 is located between the horizontal section 331 and the vertical section 333. The vertical section 333 is located at the position where the initial suspension points of the conical stringers on the horizontal section 331 are collinear. Here, the initial suspension point is the connection point between the conical cylinder 110 and the supporting chain 120 when the conical cylinder 110 slides off the stringer guide rail 320. By setting the return section 332, the vertical section 333 is restricted to such a position, thus ensuring that the conical cylinder 110 can be smoothly inserted into the conical cylinder 110 below. The return section 332 can be a structure with multiple curved paths or an inclined straight line structure. The specific implementation manner of the return section 332 in this embodiment is not limited.

[0050] The construction device 300 of the present invention also includes a chain traction mechanism 340 for pulling the supporting chain 120 to move in the chain guide rail 330. The chain traction mechanism 340 mainly includes structures such as a driving motor, a chain storage roller, and a guide. These structures can all adopt the conventional structural designs in the art.

[0051] Refer to Figure 7 , Figure 9 The platform support 310 is also provided with a flip pedal 311 and a safety ladder 312. After the flip pedal 311 is unfolded, it can overlap with the top of the pier formwork 200, facilitating the operator to come to the pier formwork 200 to install the cross beam rod 130 and convert the connection between the cross beam rod 130 and the supporting chain 120. Here, the conversion connection means that the collar on the cross beam rod 130 is connected to one of the links of the supporting chain 120. Continue to release the supporting chain 120, and the upper supporting chain 120 will become slack. Then disconnect the next link of the supporting chain 120 to complete the installation. Here, two of the supporting chains 120 need to adopt a detachable chain structure, and this structure can be implemented by using the conventional implementation methods in the art. The safety ladder 312 ensures the safety of the operator.

[0052] For the convenience of recycling, it is also possible not to adopt the connection method of the cross beam rod 130. Instead, the platform bracket 310 can be directly used to firmly support the support chain 120. After the pouring is completed, the conical cylinder 110 can be recycled section by section.

[0053] The present invention provides a method for constructing the construction device 300 using the bridge pier column concrete chain-type string tube 100, including the following steps:

[0054] S1. The operator hangs the conical cylinder 110 on the string tube guide rail 320. Under the guiding action of the string tube guide rail 320, the conical cylinder 110 moves to the horizontal section 331 of the chain guide rail 330 and is hung and connected to the support chain 120.

[0055] S2. Control the movement of the chain traction mechanism 340. When the conical cylinder 110 on the horizontal section 331 moves to the vertical section 333, stop the movement of the support chain 120.

[0056] S3. Continue to hang the conical cylinder 110. Under the guiding action of the string tube guide rail 320, the conical cylinder 110 moves to the horizontal section 331 of the chain guide rail 330 and is hung and connected to the support chain 120. One end of the bottom of this conical cylinder 110 can be inserted into the conical cylinder 110 on the vertical section 333.

[0057] S4. Repeat step S3 to complete the sequential hanging of several conical cylinders 110.

[0058] Refer to Figure 8 , complete the construction and installation before pouring according to the above steps, and then the concrete can be poured. After the pouring is completed, recycle the conical cylinder 110. The support chain 120 at the end of the chain traction mechanism 340 can be connected to the support chain 120 below. Start the chain traction mechanism 340 and run it in reverse. The conical cylinder 110 will then sequentially return from the vertical section 333 and the return section 332 to the horizontal section 331, and then the operator can take it off. In the return section 332, since the conical cylinder 110 on the horizontal section 331 is moving away from the conical cylinder 110 below in terms of path, the return section 332 is set to ensure that the conical cylinder 110 can smoothly separate from the conical cylinder 110 below during recycling, and then form a state of being suspended side by side on the horizontal section 331 in sequence, which is very convenient for the operator to take off one by one.
