Description

Technical Field

[0001] The present application relates to the field of road and bridge casting construction formwork, and in particular to an adjustable variable-section thin-walled hollow pier forming mold system. Background Art

[0002] Compared to traditional solid or hollow piers with uniform cross-sections, thin-walled hollow piers with variable cross-sections exhibit a regular, gradual slope change as the pier height increases. Due to the pier's height, construction is performed using a segmented pouring process from bottom to top. To ensure that the structural design dimensions are met, the formwork design must accommodate the dimensional variations of the pier structure.

[0003] In the prior art, when constructing the formwork for thin-walled hollow piers with variable cross-sections, wooden forms, steel forms, Visa boards, and wooden I-beams are typically used to splice the forms together. These forms are manufactured according to the designed pier dimensions, ensuring that the assembled forms meet the designed structural dimensions. The dimensions of the wooden forms, steel forms, and Visa boards must be strictly tailored to meet construction requirements, making the design and calculation of these dimensions extremely complex. During construction, once a section of the pier is cast and hardened, the formwork is removed, and a new formwork is then constructed on the cast pier.

[0004] Regarding the above-mentioned related technologies, the inventor believes that in the related technologies, multiple sets of templates need to be made when casting thin-walled hollow piers with variable cross-sections, which leads to material and labor waste in the construction process, and each set of templates can only be used for piers of one size and cannot be reused. Summary of the Invention

[0005] In order to provide a reusable template device, the present application provides an adjustable variable-section thin-wall hollow pier forming mold system.

[0006] The present application provides an adjustable variable cross-section thin-walled hollow pier forming die system that adopts the following technical solutions:

[0007] An adjustable variable-section thin-wall hollow pier forming mold system comprises an outer mold and an inner mold arranged inside the outer mold, wherein a pier casting cavity is formed between the inner mold and the outer mold;

[0008] Any pair of mutually parallel side panels on the outer mold is respectively provided with a first inclination adjustment component for adjusting the inclination of the corresponding side panels;

[0009] Any pair of mutually parallel side panels on the inner mold are respectively provided with a second inclination adjustment component for adjusting the inclination of the corresponding side panels.

[0010] By adopting the above technical solution, when casting a hollow pier, the first inclination adjustment component can be used to adjust the inclination of the side panels of the inner mold, so that the inclination of the inner wall of the hollow pier meets the design size requirements. The second inclination adjustment component can be used to adjust the inclination of the side panels of the outer mold, so that the design size of the outer wall of the hollow pier meets the requirements. After the casting of the hollow pier is completed, the outer and inner molds are disassembled, and the first and second inclination adjustment components can be used to adjust the outer and inner molds respectively, so that one set of molds can be used for hollow piers of different design specifications, allowing one set of templates to be reused. This avoids the problem of labor and material consumption in making templates before casting, and greatly saves construction costs.

[0011] Optionally, the outer mold includes two first vertical panels, two first inclined panels, and a plurality of surrounding rods, the two first vertical panels are arranged opposite to each other, the two first inclined panels are arranged opposite to each other and are located between the two first vertical panels, and the two first vertical panels and the two first inclined panels together form an outer mold with a rectangular horizontal cross-section;

[0012] The first inclination adjustment assembly is used to adjust the inclination of the first inclined panel, and the surrounding rod is used to surround and fix the first vertical panel and the first inclined panel.

[0013] By adopting the above technical solution, when it is necessary to adjust the inclination of the two first inclined panels on the outer mold, the inclination of the first inclined panel is adjusted through the first inclination adjustment component, and the surrounding rod can keep the first inclined panel of the first vertical panel connected stably, thereby enhancing the overall connection stability and strength of the outer mold. The above structure facilitates the adjustment of the outer mold, thereby enhancing the applicability of the outer mold, facilitating the reuse of the outer mold, and greatly saving construction costs.

[0014] Optionally, the guardrail includes a first guardrail located outside the first vertical panel and a second guardrail located outside the first inclined panel;

[0015] The first inclination adjustment assembly includes an adjusting screw rod, and the end of the second guard rod is fixedly connected to a mounting block. One end of the adjusting screw rod is hinged to the mounting block, and the other end passes through a horizontal slide groove on the first guard rod. The end of the adjusting screw rod passing through the first guard rod is provided with a fastener for fixing the adjusting screw rod and the first guard rod.

[0016] The first inclination adjustment assembly includes a first adjustment block and an adjustment screw rod. There are multiple first adjustment blocks, and the multiple first adjustment blocks are symmetrically distributed at the end of the first vertical panel close to the first inclined panel. The first adjustment block is detachably connected to the first vertical panel. One end of the adjustment screw rod is rotatably connected to the end of the second guard rod, and the other end passes through the first guard rod. The end of the adjustment screw rod passing through the first guard rod is provided with a fastener for fixing the adjustment screw rod and the first guard rod.

[0017] By adopting the above technical solution, when the inclination of the two first inclined panels on the outer mold is adjusted, the adjusting screw is passed through the fastener at one end of the first guard rod to loosen, and then the top of the first vertical panel is pushed to move until the overall inclination of the first vertical panel meets the requirements, and then the adjusting screw is passed through the fastener at one end of the first guard rod to tighten. The adjusting screw and the fastener can fix the first guard rod and the second guard rod, and then fix the first inclined panel of the first vertical panel to complete the adjustment of the outer mold. The above structure facilitates quick and easy adjustment of the inclination of the first inclined panel of the outer mold, and can realize adjustment of the structural dimensions of the outer mold as the pier body height increases, so that a set of templates can be reused, thereby improving the turnover rate of the template.

[0018] Optionally, the first inclination adjustment assembly includes a plurality of first adjustment blocks, which are symmetrically distributed at an end of the first vertical panel close to the first inclined panel, and the first adjustment blocks are detachably connected to the first vertical panel.

[0019] By adopting the above technical solution, a first adjustment block is set at the end of the first vertical panel. As the pier body rises, the two first adjustment blocks set at the end of the panel can be symmetrically removed, so that the width of the first vertical panel can match the distance between the two first inclined panels, thereby ensuring that the connection between the first vertical panel and the first inclined panel remains sealed and stable.

[0020] Optionally, the inner mold includes two second inclined panels, two second vertical panels and a plurality of blocking pieces, the two second inclined panels are arranged opposite to each other, the two second vertical panels are arranged opposite to each other, and the two second vertical panels and the two second inclined panels together form a rectangular inner mold;

[0021] The second inclination adjustment assembly is used to adjust the inclination of the second inclined panel; the second vertical panel is connected to the second inclined panel via a blocking piece, and the blocking piece is used to keep the connection between the second vertical panel and the second inclined panel sealed.

[0022] By adopting the above technical solution, when the inclination of the two second inclined panels on the inner mold needs to be adjusted, the inclination of the second inclined panels is adjusted using the second inclination adjustment assembly. During the adjustment process, a gap is generated at the connection between the second inclined panels and the second vertical panels. The sealing member can ensure that the connection between the second vertical panels and the second inclined panels remains sealed during the adjustment process. The above structure facilitates adjustment of the inner mold, and the sealing member keeps the inner mold as a whole sealed, thereby preventing grout leakage at the inner mold connection during casting, thereby facilitating smooth joints in the cast hollow pier body and ensuring a good appearance quality.

[0023] Optionally, the second inclination adjustment assembly includes a back rib and a plurality of tension bolts, the back rib being located on the side of the second inclined panel away from the outer mold, one end of the tension bolt being connected to the fence rod of the outer mold, and the other end extending to the side of the second inclined panel away from the outer mold and connected to the back rib.

[0024] By adopting the above technical solution, when the inclination of the two second inclined panels on the inner mold needs to be adjusted, the nuts on the back rib side of the tension bolts are loosened, and then the top of the second inclined panel can be pushed to move until the overall inclination of the second inclined panel meets the requirement. The nuts on the back rib side of the tension bolts are tightened to fix the second inclined panel and the outer mold, thus completing the adjustment of the inner mold. The above structure facilitates quick and easy adjustment of the inclination of the second inclined panels of the inner mold, and can realize the structural dimensions of the inner mold to be adjusted as the pier height increases, allowing a set of templates to be reused, thereby improving the turnover rate of the templates.

[0025] Optionally, the second vertical panel includes a plurality of detachably connected adjustment plates, and the adjustment plates are connected to the second inclined panel via a blocking piece.

[0026] By adopting the above technical solution, the second vertical panel is configured as a plurality of detachably connected adjustment plates. As the pier body rises, the two adjustment plates at the ends of the second vertical panel can be symmetrically removed, thereby allowing the width of the second vertical panel to match the distance between the two second inclined panels, thereby allowing the sealing member to always maintain a seal at the connection between the second inclined panel and the second vertical panel. Configuring the second vertical panel as a plurality of detachably connected adjustment plates allows the width of the second vertical panel to adapt to second inclined panels of various inclinations, thereby effectively enhancing the applicability of the second vertical panel. The second vertical panel does not need to be cut according to the distance between the second inclined panels, facilitating the reuse of the template.

[0027] Optionally, the blocking member is a second adjusting block, one end of the second adjusting block is connected to the end of the second inclined panel, and the other end is fixedly connected to a blocking plate, the end of the blocking plate away from the second adjusting block is overlapped with the second vertical panel, and the blocking plate is overlapped on the side of the second vertical panel close to the outer mold.

[0028] By adopting the above technical solution, when the second inclined panel tilts, it can drive the second adjusting block to tilt, and when the second adjusting block tilts, it drives the sealing plate to slide along the second vertical panel. When the two second inclined panels tilt from bottom to top toward each other, the overlapping area of the bottom of the sealing plate and the second vertical panel is larger, and the overlapping area of the top of the sealing plate and the second vertical panel is smaller, and it tilts linearly from bottom to top. The sealing plate can always keep the connection between the second inclined panel and the second vertical panel sealed, thereby avoiding leakage of slurry at the connection of the inner mold during the pouring process.

[0029] Optionally, a reinforcement is further provided on the guardrail, and the reinforcement includes a reaction frame and a reinforcement screw rod, the reaction frame is fixedly connected to the end of the first guardrail, one end of the reinforcement screw rod is rotatably connected to the second guardrail, and the other end is fixedly connected to the reaction frame.

[0030] By adopting the above technical solution, the first guard rail and the second guard rail are further reinforced by providing a reinforcement piece, which is conducive to ensuring the connection stability of the first vertical panel and the first inclined panel of the outer mold.

[0031] Optionally, the first guard bar and the second guard bar each include two channel steels, the openings of the two channel steels are set away from each other, the two channel steels are fixedly connected by bolts, a pad is provided between the two channel steels, and the pad forms a horizontal sliding groove between the two channel steels for the adjustment screw rod to pass through.

[0032] By adopting the above technical solution, the first guard bar and the second guard bar of the above structure have the advantages of simple structure and easy disassembly and assembly, and the reserved horizontal sliding groove is convenient for the tension bolts and adjustment screw to pass through the guard bar, thereby facilitating the installation and disassembly of the template, enhancing the convenience and practicality of the template device during use.

[0033] Optionally, the first vertical panel and the first inclined panel are both formed by splicing a plurality of steel templates by bolts.

[0034] By adopting the above technical solution, it is convenient to adjust the sizes of the first vertical panel and the first inclined panel according to the actual size of the hollow pier, thereby enhancing the convenience of the formwork device during use.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

When installing the template device, the inner mold 2 or the outer mold 1 can be rotated 90 degrees in the horizontal direction.

[0065] The implementation principle of an adjustable variable-section thin-walled hollow pier forming mold system in an embodiment of the present application is: during actual construction, an appropriate number of steel templates are selected according to the size of the hollow pier wall to be spliced into a first vertical panel 11, a first inclined panel 12 and a second inclined panel 21 that match the size of the hollow pier wall, and an appropriate number of adjustment plates 221 are selected to be assembled into a second vertical panel 22.

[0066] When the inclination of the two second inclined panels 21 on the inner form 2 needs to be adjusted, the nuts of the tension bolts 42 on the side of the back rib 41 are loosened, and then the top of the second inclined panel 21 can be pushed to move until the overall inclination of the second inclined panel 21 meets the requirements. The nuts of the tension bolts 42 on the side of the back rib 41 are tightened to fix the second inclined panel 21 and the outer form 1, thus completing the adjustment of the inner form 2. As the pier body rises, the two adjustment plates 221 at the ends of the second vertical panel 22 can be symmetrically removed, so that the width of the second vertical panel 22 can match the distance between the two second inclined panels 21. During actual construction, the pier body was raised by 24m, and the two adjustment plates 221 at the ends of the second vertical panel 22 were symmetrically removed.

[0067] When adjusting the inclination of the two first inclined panels 12 on the outer formwork 1, the adjusting screw 32 is passed through the fastener 321 at one end of the first guard bar 131 to loosen it, and then the top of the first vertical panel 11 is pushed to move until the overall inclination of the first vertical panel 11 meets the requirement. Then, the adjusting screw 32 is passed through the fastener 321 at one end of the first guard bar 131 to tighten it. The adjusting screw 32 and the fastener 321 can fix the first guard bar 131 and the second guard bar 132, thereby fixing the first inclined panel 12 of the first vertical panel 11 and completing the adjustment of the outer formwork 1. As the pier body rises 24 meters, the two first adjustment blocks 31 at the ends of the first vertical panel 11 can be symmetrically removed, so that the width of the first vertical panel 11 can match the distance between the two first inclined panels 12, thereby keeping the connection between the first vertical panel 11 and the first inclined panel 12 sealed and stable.
