Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a variable diameter climbing formwork system for hollow piers of ultra-high aqueducts, an arc template and its adjusting plate. Background Technology

[0002] With the rapid development of water diversion project construction in my country, aqueducts, as important structures in water diversion projects, face higher risks to safety, quality, and efficiency when constructing high piers for aqueducts across deep ditches and valleys.

[0003] Hollow piers are variable-diameter structures, wider at the bottom and narrower at the top, presenting complex construction environments and significant technical challenges. Traditional formwork techniques suffer from low efficiency, high safety risks, and are unsuitable for constructing piers over 60 meters high. Furthermore, conventional climbing formwork cannot address the variable-diameter problem of hollow pier structures. For example, patent document CN110388048A, entitled "A Hydraulic Climbing Formwork Device," describes a scheme where a sliding block is mounted on a formwork track, a formwork moving back brace is installed on the sliding block, and a formwork is mounted on the moving back brace. The sliding block moves along the formwork track under the drive of a drive assembly, simultaneously causing the formwork to close or retract. This means that the formwork can only be adjusted for angle changes, closing, and retracting, and cannot be applied to variable-diameter structures. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model aims to provide a variable-diameter climbing formwork system, an arc template, and its adjusting plates for hollow piers in ultra-high aqueducts. By selecting adjusting plates of appropriate size and quantity and changing the curvature, this system can adapt to any variable-diameter position of the hollow pier, thereby achieving the mold-closing and casting of the hollow pier.

[0005] This utility model is achieved through the following technical solution:

[0006] An adjusting plate for a variable diameter climbing formwork, wherein at least one base is provided laterally on the outer side of the adjusting plate;

[0007] Both sides of the adjusting plate are hinged with adjusting screws;

[0008] When there is a single base, the two adjusting screws are located on both sides of the base and are hinged to the base;

[0009] When there are several bases, the two adjusting screws are respectively hinged to the base closest to their outermost side;

[0010] The length of the adjusting screw is variable; and the change in the length of the adjusting screw alters the curvature of the adjusting plate.

[0011] Compared to existing technologies where conventional climbing formwork cannot solve the problem of varying diameters in hollow pier structures, this invention provides an adjustable plate for a variable-diameter climbing formwork. Specifically, since the hollow pier has a conical shape (larger at the bottom and smaller at the top), the adjustable plate can accommodate changes in diameter. The adjustable plate has at least one base on its outer side, which connects to tie rods and the template back ribs. Adjusting screws are added to both sides of the adjustable plate. The adjustable plate is preferably made of flexible material such as plywood templates, allowing it to bend through deformation. The adjusting screws are preferably manually adjustable screws; by manually adjusting their extension, the side of the adjustable plate can be pushed to adjust the curvature, thus changing the diameter of the hollow pier at that location. Since the diameter at the construction position is a pre-set value, after the curvature of the adjustable plate is adjusted to the desired position, its chord length and other parameters can be measured. The above solution allows for the selection of appropriate size and quantity of adjusting plates at any diameter change position of the hollow pier, and the curvature of the plates can be changed by adjusting the screw rod, thereby achieving the mold-closing and casting of the hollow pier at that section.

[0012] To further optimize the design and increase the circumference of the hollow pier by splicing the adjusting plates, steel sections are provided on both sides of the outer surface of each adjusting plate. Each steel section has at least two sides; one side connects to the outer surface of the adjusting plate, and the other side is perpendicular to the adjusting plate and parallel to its end face. In this design, the steel sections can be angle steel, channel steel, etc., and have at least two sides. One side is connected and fixed to the outer surface of the adjusting plate via two screw holes and bolts; the other side is located near the end of the adjusting plate's side face or flush with the end. This allows for the splicing of several adjusting plates to achieve the desired circumference of the hollow pier at that section.

[0013] Further optimization involves using angle steel as a specific structural feature of the steel profile, with bolt holes on the other side of the angle steel.

[0014] To further optimize the connection and avoid direct connection between the adjusting screw and the plate, a rib is provided on the inner side of the angle steel, and the rib is parallel to the hinge rotation surface of the adjusting screw; a pin is provided on the rib, and the adjusting screw and the pin are hingedly connected.

[0015] To further optimize the process and achieve stable adjustment of the curvature, several steel sections are evenly distributed at intervals along the length of the adjustment plate, and each steel section is provided with a corresponding base. Similarly, several bases are also evenly distributed at intervals along the length of the adjustment plate.

[0016] Further solutions:

[0017] The present invention also provides an arc template for a variable diameter climbing formwork, comprising: a plurality of adjustable plates sequentially spliced ​​along the side; to adapt to the circumference length of the hollow pier at that section.

[0018] Furthermore, angle steel is provided on both sides of the outer side of the adjusting plate. One side of the angle steel is connected to the outer side of the adjusting plate by bolts, and the other side of the angle steel is flush with the side of the adjusting plate.

[0019] The two adjacent adjustment plates are connected by bolts to each other, and the other side of the two angle steels are connected by bolts.

[0020] Furthermore, the angle steel is provided with a rib plate on its inner side, and the rib plate is parallel to the hinge rotation surface of the adjusting screw; a pin is provided on the rib plate, and the adjusting screw and the pin are hingedly connected.

[0021] Further solutions:

[0022] This invention also provides a variable-diameter climbing formwork system for hollow piers of ultra-high aqueducts, comprising:

[0023] The inner formwork located inside the hollow pier and the outer formwork located outside the hollow pier are both arc-shaped formwork.

[0024] The inner and outer templates are arranged opposite each other and connected by several tie rods, one end of which is installed on a base. In this design, the hollow pier has two cavities inside. An outer template is connected to both sides of the top of the variable diameter climbing formwork system. Two bases are provided laterally on the outer side of the outer template. The two outer templates can adapt to the curvature of the outer sides of the hollow pier respectively. The ends of the two outer templates are connected by a fixed template, thus enclosing the outer side of the hollow pier. Inner templates are set in both cavities of the hollow pier. Each inner template has a base laterally and can adapt to the curvature of the cavity protrusion. The inner template is connected to the straight section of the cavity by a fixed template to enclose the sidewall of the cavity. At this time, the outer template is connected to the inner template by several tie rods to fix the inner template. Concrete can then be poured into the gap between the outer and inner templates to form the hollow pier.

[0025] In a further optimization, the outer template is fixed to the front surface of the template back rib via a base, and the lower end of the template back rib is hinged to the rearward crossbeam on the rearward platform;

[0026] A diagonal brace is also connected between the rear surface of the template back rib and the rearward moving beam. The length of the diagonal brace is variable to drive the template back rib to rotate. In this solution, the template back rib, the rearward moving platform, the rearward moving beam, and the diagonal brace are all existing conventional technologies. The movement of the rearward moving beam can drive the outer template to close and retract. The diagonal brace can be a hydraulic rod, and the drive of the diagonal brace can drive the outer template to rotate and tilt, so as to realize the slope of the hollow pier. The remaining structure of the variable diameter climbing formwork system is also existing technology and will not be described in detail here.

[0027] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0028] This utility model provides a variable diameter climbing formwork system, an arc template and its adjusting plates for a hollow pier of an ultra-high aqueduct. By selecting the appropriate size and number of adjusting plates and changing the curvature, this system can adapt to any variable diameter position of the hollow pier, thereby realizing the mold-forming and casting of the hollow pier.

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0041] Example 1:

[0042] This embodiment 1 provides an adjusting plate for a variable diameter climbing formwork, such as... Figures 1-4 As shown ( Figure 3 and Figure 4 (The angle steel and adjusting screw 3 are not visible). At least one base 2 is provided laterally on the outer side of the adjusting plate 1; both sides of the adjusting plate 1 are hinged with adjusting screw 3.

[0043] When there is one base 2, the two adjusting screws 3 are located on both sides of the base 2 and are hinged to the base 2;

[0044] When there are several bases 2, the two adjusting screws 3 are respectively hinged to the base 2 closest to their outermost side;

[0045] The length of the adjusting screw 3 is variable; and the change in the length of the adjusting screw 3 changes the curvature of the adjusting plate 1.

[0046] Compared to existing technologies where conventional climbing formwork cannot solve the problem of varying diameters in hollow pier structures, this invention provides an adjusting plate 1 for a variable-diameter climbing formwork. Specifically, since the hollow pier has a conical shape (larger at the bottom and smaller at the top), adjusting plate 1 can accommodate changes in the pier's diameter. At least one base 2 is laterally positioned on the outer side of the adjusting plate 1, which connects to tie rods 7 and the template back rib 11. Adjusting screws 3 are added to both sides of the adjusting plate 1. The adjusting plate 1 is preferably made of flexible material such as plywood templates, allowing it to bend through deformation. The adjusting screws 3 are preferably manually adjustable screws; by manually adjusting their extension, the side of the adjusting plate 1 can be pushed to adjust the curvature, thus changing the diameter of the hollow pier at that location. The diameter at the construction position is a pre-set value; therefore, after the curvature of the adjusting plate 1 is adjusted to the desired position, its chord length and other parameters can be measured. The above scheme allows for the selection of appropriate size and quantity of adjustment plates 1 for any diameter change position of the hollow pier, and the curvature of the plates can be changed by adjusting the screw rod 3, thereby realizing the mold-forming and casting of the hollow pier at that section.

[0047] In this embodiment, to achieve the splicing of adjusting plate 1 and increase the circular length, steel profiles 4 are provided on both sides of the outer surface of the adjusting plate 1. Each steel profile 4 has at least two sides. One side of the steel profile 4 is connected to the outer surface of the adjusting plate 1, and the other side of the steel profile 4 is perpendicular to the adjusting plate 1 and parallel to the end face of the side of the adjusting plate 1. In this design, the steel profile 4 can be angle steel, channel steel, etc., and has at least two sides. One side is connected and fixed to the outer surface of the adjusting plate 1 through two screw holes and bolts; the other side is located near the end of the side of the adjusting plate 1, or flush with the end. This allows for the splicing of several adjusting plate 1s to achieve the desired circumference length of the hollow pier at that section.

[0048] In this embodiment, as a specific structure of the steel section 4, the steel section 4 is made of angle steel, and bolt holes 401 are opened on the other side of the angle steel.

[0049] In this embodiment, to connect the adjusting screw 3 and avoid direct connection between the adjusting screw 3 and the plate, a rib plate 402 is provided on the inner side of the angle steel. The rib plate 402 is parallel to the hinge rotation surface of the adjusting screw 3. A pin is provided on the rib plate 402, and the adjusting screw 3 is hinged to the pin.

[0050] In this embodiment, to achieve stable adjustment of the curvature, a plurality of steel profiles 4 are evenly distributed at intervals along the length of the adjustment plate 1, and each steel profile 4 is provided with a corresponding base 2. Similarly, a plurality of bases 2 are also evenly distributed at intervals along the length of the adjustment plate 1.

[0051] Example 2:

[0052] This embodiment 2 is a further optimization based on embodiment 1, such as... Figure 5 and Figure 6 As shown, a circular arc template for a variable diameter climbing formwork is provided, comprising:

[0053] Several adjusting plates 1 are sequentially spliced ​​along the side to adapt to the circumference length of the hollow pier at that section.

[0054] In this embodiment, angle steel is provided on both sides of the outer side of the adjusting plate 1. One side of the angle steel is connected to the outer side of the adjusting plate 1 by bolts, and the other side of the angle steel is flush with the side of the adjusting plate 1.

[0055] The two adjacent adjustment plates 1 are connected by bolts to each other and to the other side of the two angle steels.

[0056] In this embodiment, the inner side of the angle steel is provided with a rib plate 402, which is parallel to the hinge rotation surface of the adjusting screw 3; a pin is provided on the rib plate 402, and the adjusting screw 3 and the pin are hingedly connected.

[0057] Example 3:

[0058] This embodiment 3 is a further optimization based on embodiment 2, such as... Figure 7 and Figure 8 As shown, a variable-diameter climbing formwork system for hollow piers of ultra-high aqueducts is also provided, including:

[0059] The inner formwork 5 is located inside the hollow pier and the outer formwork 6 is located outside the hollow pier. Both the inner formwork 5 and the outer formwork 6 are arc-shaped formworks.

[0060] The inner template 5 and the outer template 6 are arranged opposite each other on their inner sides and are connected by several tie rods 7. One end of each tie rod 7 is installed on the base 2. In this scheme, the hollow pier has two cavities inside. An outer template 6 is connected to the top of the variable diameter climbing formwork system on both sides. Two bases 2 are provided laterally on the outer side of the outer template 6. The two outer templates 6 can respectively adapt to the curvature of the outer sides of the hollow pier. The ends of the two outer templates 6 are connected by a fixed template 12, thus enclosing the outer side of the hollow pier. An inner template 5 is set in each of the two cavities of the hollow pier. The inner template 5 is provided with a base 2 laterally. The inner template 5 can adapt to the curvature of the cavity protrusion, and the straight section of the inner template 5 in the cavity is connected by a fixed template 12 to enclose the side wall of the cavity. At this time, the outer template 6 is connected to the inner template 5 by several tie rods 7, thus fixing the inner template 5. In this way, concrete can be poured in the gap between the outer template 6 and the inner template 5 to form a hollow pier.

[0061] In this embodiment, the outer template 6 is fixed to the front surface of the template back rib 11 by the base 2, and the lower end of the template back rib 11 is hinged to the rearward crossbeam 8 on the rearward platform 10.

[0062] A diagonal brace 9 is also connected between the rear surface of the template back rib 11 and the rearward moving beam 8. The length of the diagonal brace 9 is variable, so as to drive the template back rib 11 to rotate. In this solution, the template back rib 11, the rearward moving platform 10, the rearward moving beam 8, and the diagonal brace 9 are all existing conventional technologies. The movement of the rearward moving beam 8 can drive the outer template 6 to close and retract. The diagonal brace 9 can be a hydraulic rod. The drive of the diagonal brace 9 can drive the outer template 6 to rotate and tilt, so as to realize the inclined surface of the hollow pier. The remaining structure of the variable diameter climbing formwork system is also existing technology, and will not be described in detail here.
