Summary of the invention

[0004] The purpose of this application is to provide a fine-tuning device for a special-shaped clear water column template.

[0006] By adopting the above technical solution, the formwork panel is the core component of the special-shaped clear water column formwork, which is in direct contact with the concrete. The formwork panel is made of high-quality wood with a density of about 0.8g / cm³ and an elastic modulus ≥10GPa to limit the appearance shape and dimensional accuracy of the special-shaped clear water column. Then, the formwork panel is tightly connected to the outer support frame of the formwork at the outer edge, and the inner support frame of the formwork is fixed at the inner edge of the formwork panel to provide all-round support for the formwork panel to ensure the stability of the formwork panel during the concrete pouring process. Then, at the position of the special-shaped bending area of ​​the formwork panel, the reserved bundling interval is reserved. When tying the steel bar skeleton, the spacing of the steel bars in the bending area is adjusted. The spacing of the steel bars on the side where the curvature needs to be increased is appropriately reduced to make the steel bars on this side relatively dense. Therefore, when pouring concrete, the steel bars on this side have a relatively greater restraining effect on the concrete, which can increase the curvature of the concrete surface accordingly. On the side where the curvature needs to be reduced, the spacing of the steel bars is appropriately increased, and the fine-tuning structure set on both sides of the formwork panel is used to tighten the formwork panel through the formwork fine-tuning structure to reduce the strength required for the structure of the formwork panel during the tightening process, so that the construction personnel can accurately adjust the position and angle of the formwork panel during the construction process, thereby ensuring the angular stability of the special-shaped position during the pouring of the special-shaped clear water column.

[0007] The support and tightening assembly includes a second fixed frame, a wire-paying plate, a wire tube, a screw and a connecting base, and the side of the second fixed frame is installed with the wire-paying plate by bolts, and the wire tubes are installed with bolts on both sides of the wire-paying plate, and the side of the second fixed frame away from the wire-paying plate is installed with a screw by bolts, and the outer diameter surface of the screw is sleeved on the connecting base.

The wire tubes on both sides of the wire-releasing plate are used to position the tightening steel rope and provide wear-resistant protection for the contact surface of the steel rope during the tightening process, thereby ensuring its smoothness during movement, and the connecting base sleeved on the outer diameter surface of the screw rod is connected to the template external support frame on the template panel, thereby completing The support and tightening assembly is fixed, and then the position of the screw on the connecting base is adjusted by rotating the screw, so that the second fixing frame installed on the screw moves as the construction personnel adjust the position of the screw by turning the hand wheel, and the tightening steel rope placed at the outlet end of the wire tube is connected to the template panel to adjust the tightness of the rope connected to the support and tightening assembly, and the rope is connected by adjusting the pin installed above the contact plate, and the template panel connected to the rope is slightly adjusted by adjusting the pin, and then the template panel is adjusted to achieve the tightening and fixation of the template.

[0009] The support and tightening assembly also includes an adjusting contact plate, a pin, a rotating hand wheel and a tightening steel rope, and the pin is installed above the adjusting contact plate, and the end of the screw rod away from the second fixed frame is rotatably connected to the rotating hand wheel, and the tightening steel rope is placed at the outlet end of the wire tube.

[0010] By adopting the above technical solution, the pin passes through the position of the rope, thereby changing the tension of the rope by moving the pin on the adjustment contact plate, thereby completing the fine adjustment of the template panel. Then the rotation of the hand wheel is converted into the linear displacement of the steel rope, driving the angle change of the template panel.

[0011] The second adjusting base includes a connecting frame, a limiting frame, a first fixing frame, a connecting assembly, a connecting rod and a supporting rod, and the side edges of the connecting frame are provided with limiting frames, and the first fixing frames are installed on both sides of the limiting frame by bolts, and the connecting assembly is installed on the bottom end of the connecting frame by bolts, and the connecting frame and the limiting frame are connected to the connecting rod by the first fixing frame and the connecting assembly, and the supporting rod is installed at the inner edge of the connecting frame by bolts, and the second adjusting base has the same structure as the first adjusting base.

[0012] By adopting the above technical solution, the second adjustment base serves as the mounting base of the fine-tuning mechanism, and the connecting frame and the limit frame form a rigid frame, wherein the connecting frame is made of aluminum alloy with a hardness of HB ≥ 70. The limit frame constrains the travel of the tensioning and tightening bracket to prevent over-adjustment. The support rod enhances the bending resistance of the base.

Then the first limiting rope and the second limiting rope can accurately control the position and angle of the template by adjusting their tension, thereby completing the fixation of the second adjustment base and the first adjustment base on the template panel. Then, the gaskets installed on both sides of the first limiting rope and the second limiting rope play a buffering and protective role to prevent the ropes from wearing or breaking when subjected to force.

[0022] By adopting the above technical solution, the three groups of bundled steel bars, namely the first bundled steel bars, the second bundled steel bars and the limiting rods, are staggeredly arranged to form a mesh support, thereby enhancing the deformation resistance of the edge of the formwork, and are bound to the formwork panel by the limiting rods to constrain the displacement of the panel. The staggered binding of the steel bars provides bidirectional stiffness to adapt to the curved surface load of the special-shaped column; the metal wire binding can be partially disassembled and adjusted, and the external support frame of the formwork can be used as a fixing point of the formwork fine-tuning structure to install the second adjustment base and the first adjustment base of the formwork fine-tuning structure.

The tightening steel rope placed at the outlet of the wire tube is connected to the template panel to adjust the tightness of the rope connected to the support tightening assembly. The rope is connected by adjusting the pin installed above the contact plate. The template panel connected to the rope is slightly adjusted by adjusting the pin, and then the template panel is adjusted to achieve the tightening and consolidation of the template. 3. The pin passes through the position of the rope, so that the tension of the rope can be changed by moving the pin on the adjustment contact plate, thereby completing the fine adjustment of the template panel.

The support tightening component 9 is an adjustment structure for fine-tuning the inclination and stability of the special-shaped angle of the template, wherein the second fixing frame 16 is used to adjust the length of the connected rope, and the wire-laying plate 17 installed on its side is for tightening the steel rope 24. The arrangement and guidance provide a platform, and the wire tubes 18 on both sides of the wire release plate 17 are used to position the tightening steel rope 24, and to provide wear-resistant protection for the contact surface of the tightening steel rope 24 during the tightening process, thereby ensuring its smoothness during movement. The connecting base 20 is sleeved on the outer diameter surface of the screw rod 19, and then the connecting base 20 is connected to the template external support frame 2 on the template panel 1, thereby completing the fixation of the support tightening assembly 9, and then the position of the screw rod 19 on the connecting base 20 is adjusted by rotating the screw rod 19. The second fixing frame 16 installed on the screw rod 19 moves as the construction personnel adjust the position of the screw rod 19 by turning the hand wheel 23. The tightening steel rope 24 placed at the outlet end of the wire tube 18 is connected to the template panel 1 to adjust the tightness of the rope connected to the support tightening assembly 9. The rope is wound by adjusting the pin 22 installed above the contact plate 21. The template panel 1 connected to the rope is fine-tuned by adjusting the pin 22, and then the template panel 1 is adjusted to tighten and fix the template. The pin 22 passes through the position of the rope, and the pin 22 is moved on the adjustment contact plate 21 to change the tightness of the rope, thereby completing the fine-tuning of the template panel 1. The rotation of the hand wheel 23 is then converted into a linear displacement of the steel rope, driving the angle of the template panel 1 to change.The second adjustment base 6 serves as the mounting base of the fine-tuning mechanism, and the connecting frame 601 and the limit frame 602 form a rigid frame, wherein the connecting frame 601 is aluminum alloy with a hardness of HB ≥ 70, and the limit frame 602 constrains the travel of the tensioning and tightening bracket 7 to prevent over-adjustment, and the support rod 606 enhances the bending resistance of the base. The split base design allows independent adjustment of different areas, and the limit frame 602 and the support rod 606 form double stability. The locking shaft 702 installed between the two sets of tightening winding plates 701 is the core component of the entire bracket. By rotating the locking shaft 702, the tightening winding plate 701 can be tightened and relaxed, and then the first limit rope 706 and the second limit rope 707 can accurately control the position and Angle, thereby completing the fixation of the second adjustment base 6 and the first adjustment base 5 on the template panel 1, and then the gaskets 705 installed on both sides of the first limiting rope 706 and the second limiting rope 707 play a buffering and protective role, preventing the ropes from being worn or broken when subjected to force. According to actual construction needs, bundling operations can be performed at different positions, and prestressed steel bar areas are set in the skeleton, and the steel bar spacing is appropriately reduced on the side where the curvature needs to be increased, so that the steel bars on this side are relatively dense. When pouring concrete, the steel bars on this side have a relatively large restraining effect on the concrete, which can increase the curvature of the concrete surface accordingly; on the side where the curvature needs to be reduced, the steel bar spacing is appropriately increased, thereby improving the flexibility and stability of the template connection, wherein when the rope is passed through, wherein The rope is placed above the wire-releasing groove of the wire-clamping mounting seat. The arc shape of the wire-releasing groove itself ensures that the friction between the rope and the contact surface during movement will not cause the rope to be cut. The first connecting plate 11 and the second connecting plate 15 serve as the core frame of the connection component 604, connecting the fixed shaft 1101, the outlet installation head 12 and the locking bracket to form a stable rigid platform, and evenly transfer the tension of the tensioning steel rope to the template fine-tuning structure 3 to avoid local stress concentration, and connect the fixed shaft 1101 as the hinge axis between the first connecting plate 11 and the second connecting plate 15, allowing the component to rotate slightly around the axis during the fine-tuning process to adapt to angle changes, and the outlet installation head 12 guides the steel rope, wherein the outlet installation head 12 has a built-in ceramic bushing , guide the tightening steel rope 24 to enter the wire tube 18 along the preset path, reduce friction loss, and disperse the concentrated stress of the steel rope through the arc-shaped outlet to prevent the risk of wire breakage caused by sharp-angle bending. Then the first locking bracket 13 and the second locking bracket 14 form a double lock to ensure that the steel rope does not fall off under extreme loads. The first bundled steel bars 201, the second bundled steel bars 202, and the limiting rod 203 are arranged in an interlaced manner to form a mesh support to enhance the deformation resistance of the template edge. The template panel 1 is tied with the limiting rod 203 to constrain the panel displacement. The staggered tying of the steel bars provides bidirectional stiffness to adapt to the curved surface load of the special-shaped column; the metal wire bundling can be partially disassembled and adjusted, and the template external support frame 2 can be used as a fixing point for the template fine-tuning structure 3.To install the second adjustment base 6 and the first adjustment base 5 of the template fine-tuning structure 3.
