Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a high pier extension template device. Background Technology

[0002] In highway bridge construction in Cambodia, the construction of high-pier concrete is a commonly used technique due to its advantages such as simple operation, reliable quality, and low cost. While the construction process for high-pier concrete is relatively simple, effective quality control is crucial. Currently, high-pier concrete construction in Cambodia often employs a formwork-changing method. Typically, the construction site involves segmented large steel formwork, construction platforms, formwork fixing frames, lifting equipment, and installation facilities. One formwork section is left in place, and the bottom section is removed and raised. This alternating raising of the two sections increases the pier height until the designed construction height is reached. However, after each formwork change, the flatness and dimensions of the formwork need to be checked, and the surface must be carefully finished to ensure the appearance quality of the concrete and the pier's alignment, preventing issues such as misalignment and surface defects (segmented control of single-pour volume). This significantly reduces the efficiency of formwork installation and removal, increasing construction complexity and time.

[0003] In view of the shortcomings of the existing technology of using formwork for high pier concrete construction, those skilled in the art have been looking for solutions. Utility Model Content

[0004] The purpose of this utility model is to provide a high-pillar extension template device to solve the problems of low precision in dispensing positioning and low product yield caused by factors such as fixture size, clamping force, and fixture positioning in the dispensing operation in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides a high-pier extension template device, which includes: a processing platform, a high-pier template, and two fixing components symmetrically installed on both sides of the high-pier template, and detachably installing the high-pier template onto the processing platform; wherein...

[0006] The high pier formwork includes: a fixed formwork and several connecting formworks. According to the height of the high pier, a corresponding number of connecting formworks are stacked and installed on the fixed formwork so that the height of the high pier formwork meets the construction requirements of the high pier.

[0007] Each fixing component includes: several U-shaped retaining edges, a lead screw, and a nut that matches the lead screw. Each U-shaped retaining edge is installed on one side of the fixing template or connecting template with its opening facing outward. The first end of the lead screw passes through the U-shaped groove formed by all the U-shaped retaining edges, and the second end of the lead screw is exposed in the U-shaped groove and is fastened with the nut.

[0008] The processing platform includes a top plate, the fixed template is set on the top plate, and a threaded groove is opened at the U-shaped edge of the two fixed components on the top plate to restrict the first end of the lead screw.

[0009] Optionally, in the high pier extension template device, the fixed template includes: a first body and a plurality of first positioning holes opened on the top of the first body.

[0010] Optionally, in the high pier extension template device, the connecting template includes: a second body, a plurality of second positioning holes opened on the top of the second body, and a plurality of positioning protrusions opened on the bottom of the second body; the position and number of the first positioning holes on the fixed template are adapted to the positioning protrusions on the connecting template, and the position and number of the second positioning holes on one of the two adjacent connecting templates are adapted to the positioning protrusions on the other connecting template.

[0011] Optionally, in the high pier extension template device, the first body and the second body have the same size and shape.

[0012] Optionally, in the high pier extension template device, an opening is provided on the top plate in a predetermined area between two threaded grooves, and the opening is located at the bottom of the high pier template.

[0013] Optionally, in the high pier extension template device, the processing platform further includes: a base disposed below the top plate, a first support seat disposed at the middle position between the top plate and the base, and a second support seat disposed between the top plate and the base and located on both sides of the first support seat.

[0014] Optionally, the high pier extension template device further includes: a demolding assembly disposed in the processing platform. The demolding assembly includes: two sliding seats, two sets of brackets, two hydraulic rods, and a support platform. The two sliding seats are disposed between the top plate and the base located on both sides of the first support seat, and the top and bottom ends of each sliding seat are slidably connected to the top plate and the base, respectively. The two sets of brackets are symmetrically disposed on both sides of the first support seat, with one end of each bracket hinged to the side wall of the adjacent sliding seat and the other end hinged to the support platform. The two hydraulic rods are symmetrically disposed on both sides of the first support seat, with each hydraulic rod fixed at the middle position of the adjacent sliding seat, and the driving end of the hydraulic rod is fixedly connected to the first support seat. Based on the movement of the hydraulic rods, the sliding seats fixed to them slide, and the sliding of the sliding seats drives the brackets hinged to them to move in linkage. In turn, the brackets push the support platform hinged to them to move up and down relative to the top plate through the opening on the top plate, so as to adjust the height of the support platform inside the high pier template.

[0015] Optionally, in the high pier extension formwork device, each set of supports includes several supports.

[0016] Optionally, in the high pier extension template device, the number of U-shaped retaining edges in each fixing component is one more than the number of connecting templates.

[0017] The high-pier formwork of this invention is based on the superposition of fixed and connecting formwork. This flexible superposition allows for efficient formwork installation and dismantling. The total height of the high-pier formwork can be adjusted by changing the number of connecting formwork, thus flexibly meeting the height requirements of the high pier. Furthermore, based on the structural design of the fixed components, the superimposed high-pier formwork forms a stable overall structure while allowing for rapid assembly and disassembly on the processing platform. This facilitates operation, disassembly, and transportation, and also reduces quality problems such as misalignment and surface defects.

[0018] On the other hand, based on the structural design of the demolding component, the forming height of the high pier can be quickly adjusted by adjusting the height of the support platform inside the high pier formwork. After the high pier is formed, the formed high pier is pushed upward based on the support platform to realize the demolding and transportation of the high pier. This effectively reduces the difficulty of demolding the high pier, saves time and effort, and reduces construction costs. Attached Figure Description

The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] In the description of the utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of a utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In utility models, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the utility model according to the specific circumstances.

[0031] Please refer to Figure 1 This is a three-dimensional schematic diagram of a high-pier extension template device in one embodiment of this utility model. Figure 1As shown, the high pier extension template device includes: a processing platform 20, a high pier template 30, and two fixing components 4 symmetrically installed on both sides of the high pier template 30, and detachably installed on the processing platform 20 for the high pier template 30; wherein, the high pier template 30 includes: a fixed template 2 and several connecting templates 3, and a corresponding number of connecting templates 3 are stacked and installed on the fixed template 2 according to the height of the high pier, so that the height of the high pier template 30 meets the construction requirements of the high pier; each fixing component 4 includes: several U-shaped retaining edges 41, a threaded rod 43, and a threaded rod 4 3. Matching nuts 44, each U-shaped retaining edge 41 with its opening facing outwards, are installed on one side of the fixed template 2 or the connecting template 3; the first end of the screw 43 passes through the U-shaped groove formed by all the U-shaped retaining edges 41, and the second end of the screw 43 is exposed in the U-shaped groove and is fastened with the nut 44, thus fixing the high-pillar template 30 as a whole on the processing platform 20; the processing platform 20 includes: a top plate 1, the fixed template 2 is set on the top plate 1, and a threaded groove 42 is opened on the top plate 1 at the U-shaped retaining edges 41 adjacent to the two fixed components 4 to restrict the first end of the screw 43.

[0032] The high pier extension formwork device of the present invention increases the height of the high pier formwork by superimposing connecting formwork 3 on the fixed formwork 2. After the construction is completed, the entire formwork is removed. This can reduce the volume of concrete poured each time, reduce quality problems such as misalignment and pitting, and has a great advantage in controlling the quality of bridge piers.

[0033] Preferably, the number of U-shaped retaining edges 41 in each fixing component 4 is one more than the number of connecting templates 3. In other words, in order to securely install the entire high-pier template onto the processing platform 20, U-shaped retaining edges 41 are provided on both sides of each fixing template 2 and each connecting template 3 in the high-pier template, so that the lead screw 43 establishes a connection between each stacked template. It can be understood that the number of U-shaped retaining edges 41 in each fixing component 4 of the present invention includes, but is not limited to, one more than the number of connecting templates 3, and may be less than the number of connecting templates 3. The principle for selecting the number is that the U-shaped retaining edges 41, combined with the stacked templates, can better limit the lateral displacement of the high-pier template constructed by stacking.

[0034] Please refer to Figures 1 to 4In the specific construction application of the high pier extension formwork device, firstly, select the number of connecting templates 3 according to the height of the high pier, and then stack the connecting templates 3 sequentially onto the fixed template 2 to form the high pier formwork. By adjusting the number of connecting templates 3, the total height of the high pier formwork can be adjusted to flexibly adjust the height of the high pier. After the connecting templates 3 are installed, the first end of the screw 43 passes through (along) the U-shaped groove formed by all the U-shaped clamps 41 and connects with the threaded groove 42. The connection between the screw 43 and the threaded groove 42 not only fixes the screw 43, but also makes the screw 43 abut against the U-shaped groove to limit the fixed template 2 and the connecting template 3, preventing the connecting template 3 from shifting laterally. Subsequently, the second end of the screw 43 is connected by the nut 44 to fix the U-shaped groove, preventing the connecting template 3 from shifting vertically, and achieving rapid fixation of the connecting template 3. Based on the fixing component 4, the fixed template 2 and the connecting template 3 can be quickly fixed into a stable high pier formwork. Finally, concrete for the high pier is added into the space inside the high pier formwork to form the high pier.

[0035] Based on the structural design of the fixed components, the stacked high pier formwork forms a stable overall structure, and the high pier formwork can be quickly assembled and disassembled on the processing platform. This makes the operation convenient, facilitates disassembly and transportation, and also reduces quality problems such as misalignment and pitting.

[0036] Please refer to Figure 1 and Figure 4 The fixed template 2 includes: a first body 21 and a plurality of first positioning holes formed on the top of the first body 21. Please refer to... Figure 4 The connecting template 3 includes: a second body 31, a plurality of second positioning holes 32 opened on the top of the second body 31, and a plurality of positioning protrusions 33 opened on the bottom of the second body 31; the position and number of the first positioning holes on the fixing template 2 are adapted to the positioning protrusions 33 on the connecting template 3, and the position and number of the second positioning holes 32 on one of the two adjacent connecting templates 3 are adapted to the positioning protrusions 33 on the other connecting template 3.

[0037] Based on the structural design of the fixed template 2 and the connecting template 3, they are designed to have positioning holes (first positioning hole or second positioning hole) and / or positioning protrusions. When the templates are stacked (including two cases: connecting template stacked on fixed template, connecting template stacked on connecting template), the positioning protrusions are inserted into the positioning holes to facilitate accurate stacking of the templates and improve the stability of the stacking of the two templates.

[0038] Specifically, the first body 21 and the second body 31 have the same size and shape so that they can be stacked and assembled to conform to the overall shape of the construction pier.

[0039] Please refer to Figure 5The processing platform 20 further includes: a base 7 disposed below the top plate 1, a first support 8 disposed at the middle position between the top plate 1 and the base 7, and a second support 9 disposed between the top plate 1 and the base 7 and located on both sides of the first support 8. An opening 5 is provided on the top plate 1 in a predetermined area between the two threaded grooves 42, and the opening 5 is located at the bottom of the high-support template 30.

[0040] Please refer to Figure 1 , Figure 2 and Figure 5 The high-pier extension template device further includes a demolding assembly 10 disposed in the processing platform 20. The demolding assembly 10 includes two sliding seats 101, two sets of supports, two hydraulic rods 103, and a support platform 104. The two sliding seats 101 are disposed between the top plate and the base located on both sides of the first support 8, and the top and bottom ends of each sliding seat 101 are slidably connected to the top plate 1 and the base 7, respectively. The two sets of supports are symmetrically disposed on both sides of the first support 8. One end of each support 102 is hinged to the side wall of the adjacent sliding seat 101, and the other end is connected to the support platform 104. 4. Hinged connection; Two hydraulic rods 103 are symmetrically arranged on both sides of the first support base 8. Each hydraulic rod 103 is fixed to the middle position of the adjacent sliding seat 101, and the driving end of the hydraulic rod 103 is fixedly connected to the first support base 8. Based on the operation of the hydraulic rod 103, the sliding seat 101 fixed to it slides, and the sliding of the sliding seat 101 drives the hinged bracket 102 to move in conjunction with it. In turn, the bracket 102 pushes the hinged support platform 104 to move up and down relative to the top plate 1 through the opening 5 on the top plate 1, so as to adjust the height of the support platform 104 inside the high pier formwork 30. Specifically, each set of brackets includes several brackets 102, which can support and push the support platform 104 to move up and down.

[0041] In this embodiment, as Figure 5 As shown, the support platform 104 is set in the opening 5 of the top plate 1 of the processing platform 20. The size of the support platform 104 matches the size of the opening, and the shape and position of the opening correspond to the shape and position of the fixed template and the connecting template. This allows the top plate 1 to support the high pier template while supporting the support platform 104 to move up and down, allowing it to enter / move away from the interior of the high pier template 30. This enables the high pier to be quickly adjusted in forming height. After the high pier is formed, the support platform pushes the high pier upward, facilitating demolding and transportation of the high pier.

[0042] The high-pier formwork of this invention is based on the stacking of fixed and connecting formwork. This flexible stacking allows for efficient formwork installation and dismantling. The total height of the high-pier formwork can be adjusted by changing the number of connecting formwork, thus flexibly meeting the height requirements of the high pier. Furthermore, the structural design based on the fixed components allows the stacked high-pier formwork to form a stable overall structure while enabling rapid assembly and disassembly on the processing platform. This facilitates operation, disassembly, and transportation, and reduces quality problems such as misalignment and surface defects. On the other hand, the structural design based on the demolding components allows for rapid adjustment of the high-pier's forming height by adjusting the height of the support platform inside the high-pier formwork. After the high-pier is formed, it is pushed upwards by the support platform, facilitating demolding and transportation. This effectively reduces the difficulty of demolding, saves time and effort, and lowers construction costs. It is understood that the above examples are merely illustrative examples for better understanding the technical solutions of the embodiments of this application and are not intended to limit the scope of these embodiments.

[0043] Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by this application.

[0044] Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Therefore, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model also intends to include these modifications and variations.
