Description

Technical Field

[0001] The present application relates to the technical field of bridge construction equipment, and in particular to a production and construction mold for prefabricated box beam components. Background Art

[0002] A box girder is a type of beam used in bridge engineering. It is hollow inside and has flanges on both sides of the upper part. It is divided into single-box and multi-box types. Box girders prefabricated in an independent site can be erected after the lower project is completed in combination with a bridge-erecting machine, which can speed up the project progress and save construction time. Box girders with reinforced concrete structures are divided into prefabricated box girders and cast-in-place box girders.

[0003] In related technologies, cast-in-place box girders are mainly used in the construction of large continuous bridges. The formwork of cast-in-place box girders mostly adopts steel formwork. The steel formwork has a large dead weight and requires a supporting structure to support the formwork of the cast-in-place box girder. The traditional fixed steel structure support is used as the supporting structure of the cast-in-place box girder formwork. It has a simple structure and is easy to install.

[0004] However, since the size of the standard steel structure support has been finalized, when the box girder specifications change, the original standard steel structure support cannot be reused and can only be reprocessed according to the new beam height, which has poor adaptability and increases the cost of engineering construction. Summary of the Invention

[0005] An embodiment of the present application provides a box girder prefabricated component production and construction mold to solve the problem of poor adaptability of the cast-in-place box girder formwork support structure in the related art.

[0009] In some embodiments, the clamping structure includes a plurality of pin holes arranged on the first lower support and surrounding the outer circumference of the pin shaft, and a clamping hole arranged on the first upper support. The clamping structure also includes a pin, which is used to pass through the pin hole and the clamping hole to limit the relative rotation of the first upper support and the first lower support.

[0010] In some embodiments, the first hydraulic cylinder is connected to the wing template through a second hinge support, the second hinge support includes a second upper support and a second lower support hinged by a pin shaft, the second upper support and the wing template are connected by bolts, and a second hydraulic cylinder is fixed between the two second upper supports.

[0011] In some embodiments, a box girder formwork assembly is further included, wherein the box girder formwork assembly includes a bottom formwork, a web formwork, the wing formwork, an edge formwork, and an inner formwork.

[0012] In some embodiments, a stopper for supporting the side template is rotatably connected to the second upper support away from the web template, and an angle adjustment mechanism is provided between the stopper and the second upper support.

[0013] In some embodiments, a third hydraulic cylinder is hinged on the base for connecting to and supporting the belly template.

[0014] In some embodiments, the end of the web formwork away from the wing formwork is fixedly connected to a pad for supporting the bottom formwork, and connecting strips for closing the casting gap are connected between adjacent two formworks among the bottom formwork, web formwork, wing formwork, and side formwork.

Therefore, by controlling the extension length of the second hydraulic cylinder, the position of the two first hydraulic cylinder support ends can be adjusted to support wing templates of different widths. At the same time, by controlling the extension length of the two first hydraulic cylinders, the installation position of the wing template can be adjusted. Then, when prefabricating box girders of different specifications, the installation requirements of the corresponding wing templates can be met, and they can be reused, thereby improving the adaptability of the support structure and helping to reduce the cost of engineering construction.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] An embodiment of the present application provides a box girder prefabricated component production and construction mold, which can solve the problem of poor adaptability of the cast-in-place box girder formwork support structure in the related art.

[0029] See also Figures 1 to 5 As shown, the embodiment of the present application provides a box beam prefabricated component production and construction mold, including:

[0030] The support assembly 100 includes a base 110, on which two first hydraulic cylinders 120 are hingedly connected for connecting and supporting the wing template 230, and a second hydraulic cylinder 130 is hinged between the two first hydraulic cylinders 120. The second hydraulic cylinder 130 is used to adjust the position of the supporting ends of the two first hydraulic cylinders 120 to adapt to wing templates 230 of different widths.

[0031] The support assembly 100 of the box girder prefabricated component production and construction mold in the embodiment of the present application is provided with a base 110, on which two first hydraulic cylinders 120 for connecting and supporting the wing formwork 230 are hingedly connected, and a second hydraulic cylinder 130 is hinged between the two first hydraulic cylinders 120, and the second hydraulic cylinder 130 is used to adjust the positions of the supporting ends of the two first hydraulic cylinders 120 to adapt to wing formworks 230 of different widths.

[0032] During specific implementation, the base 110 is arranged at a suitable position, and the extension length of the two first hydraulic cylinders 120 is adjusted according to the specifications of the required prefabricated box beam, and the extension length of the second hydraulic cylinder 130 is adjusted so that the positions of the support ends of the two second hydraulic cylinders 130 remain at suitable positions, and the wing formwork 230 is fixed at the position of the support end of the second hydraulic cylinder 130 to form an installation positioning for the wing formwork 230, and then the corresponding bottom formwork 210, web formwork 220, wing formwork 230, side formwork 240 and inner formwork 250 are installed.

[0033] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a box girder prefabricated component production and construction mold, wherein the first hydraulic cylinder 120 of the box girder prefabricated component production and construction mold is connected to the base 110 through a first hinge support 140, and the first hinge support 140 includes a first upper support 141 and a first lower support 142 hinged by a pin shaft, and a clamping structure for limiting relative rotation is provided between the first upper support 141 and the first lower support 142.

[0034] The first hydraulic cylinder 120 of the box girder prefabricated component production construction mold in the embodiment of the present application is connected to the base 110 through the first hinge support 140. The first hinge support 140 includes a first upper support 141 and a first lower support 142 hinged by a pin shaft. A clamping structure for limiting relative rotation is provided between the first upper support 141 and the first lower support 142.

[0035] In a specific implementation, the base plate is made of a metal plate, the first lower support 142 is welded to the base 110, and the first upper support 141 is welded to one end of the first hydraulic cylinder 120, so that the first hydraulic cylinder 120 can swing on the base 110. At the same time, because a clamping structure is provided between the first upper support 141 and the first lower support 142 to limit relative rotation, after the first hydraulic cylinder 120 swings, when the first upper support 141 and the first lower support 142 form a suitable angle, the clamping structure can conveniently position the first upper support 141, so that the first hydraulic cylinder 120 can provide stable support for the wing template 230 at this angle.

[0036] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a box girder prefabricated component production and construction mold, the clamping structure of the box girder prefabricated component production and construction mold includes a plurality of pin holes 143 arranged on the first lower support 142 and surrounding the outer periphery of the pin shaft, and a clamping hole 144 arranged on the first upper support 141, and the clamping structure also includes a pin 145, which is used to pass through the pin hole 143 and the clamping hole 144 to limit the relative rotation of the first upper support 141 and the first lower support 142.

[0037] The clamping structure of the box girder prefabricated component production and construction mold in the embodiment of the present application includes a plurality of pin holes 143 arranged on the first lower support 142 and surrounding the outer periphery of the pin shaft, and a clamping hole 144 arranged on the first upper support 141. The clamping structure also includes a pin 145, which is used to pass through the pin hole 143 and the clamping hole 144 to limit the relative rotation of the first upper support 141 and the first lower support 142.

[0038] In specific implementation, when the first hydraulic cylinder 120 rotates to a suitable angle to support the wing template 230, the first upper support 141 is positioned on the first lower support 142 by passing the pin 145 through the pin hole 143 and the card hole 144 at the corresponding position, so that the first hydraulic cylinder 120 connected to the first upper support 141 is maintained at this angle and forms a stable support.

[0039] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a box girder prefabricated component production and construction mold, in which the first hydraulic cylinder 120 of the box girder prefabricated component production and construction mold is connected to the wing template 230 through a second hinge support 150, and the second hinge support 150 includes a second upper support 151 and a second lower support 152 hinged by a pin shaft, and the second upper support 151 and the wing template 230 are connected by bolts, and a second hydraulic cylinder 130 is fixed between the two second upper supports 151.

[0040] The first hydraulic cylinder 120 of the box girder prefabricated component production construction mold in the embodiment of the present application is connected to the wing formwork 230 through the second hinge support 150. The second hinge support 150 includes a second upper support 151 and a second lower support 152 hinged by a pin shaft. The second upper support 151 and the wing formwork 230 are connected by bolts, and the second hydraulic cylinder 130 is fixed between the two second upper supports 151.

[0041] During specific implementation, bolt holes for installing the wing template 230 are opened on the second upper support 151, the second lower support 152 is fixedly connected to the telescopic end of the first hydraulic cylinder 120, and the two ends of the second hydraulic cylinder 130 are respectively fixedly connected to the second upper support 151. The supporting surfaces on the second upper supports 151 at both ends of the second hydraulic cylinder 130 are located on the same plane, which facilitates the installation of the wing template 230.

[0042] It should be noted that, by designing the second hydraulic cylinder 130 to be connected to two small second upper supports 151 , the problem of the second upper supports 151 being too small and easily lost during storage can be avoided.

[0043] At the same time, under the connection of the second hydraulic cylinder 130, it can be stored when retracted, and can also adapt to different wing templates by stretching. The connection can also serve as a positioning function to ensure that the supporting surfaces of the two second upper supports 151 are located on the same plane, further improving the applicability while ensuring the stability of the support of the wing template by the first hydraulic cylinder 120.

[0044] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a box girder prefabricated component production and construction mold, which also includes a box girder formwork assembly 200, and the box girder formwork assembly 200 includes a bottom formwork 210, a web formwork 220, a wing formwork 230, an edge formwork 240 and an inner formwork 250.

[0045] The box girder prefabricated component production construction mold of the embodiment of the present application also includes a box girder formwork assembly 200, and the box girder formwork assembly 200 includes a bottom formwork 210, a web formwork 220, a wing formwork 230, an edge formwork 240 and an inner formwork 250.

[0046] During specific implementation, bottom formwork 210, web formwork 220, wing formwork 230, side formwork 240 and inner formwork 250 of appropriate specifications are manufactured according to the specifications of the required prefabricated box girder. The bottom formwork 210 is arranged on the ground, the web formwork 220 is connected to both sides of the bottom formwork 210, the wing formwork 230 is connected to the web formwork 220 on both sides, and the side formwork 240 is connected to the wing formwork 230 on both sides. The inner formwork 250 fixes the inner position formed by the bottom formwork 210, web formwork 220, wing formwork 230 and side formwork 240. The inner formwork 250 is composed of a flat plate, columns and side columns.

[0047] It should be noted that the material of the formwork can be wood or metal, and the choice is determined according to actual conditions. If the prefabricated box beam is small in size, wooden boards can be used. They are small in size and light in weight. Even if the wooden boards are deformed or rotten due to various reasons, the large pieces can be cut into small pieces, and the flat parts can be retained. In terms of function, the web formwork 220 is changed to the wing formwork 230 or even the side formwork 240, and wood is used as much as possible to reduce waste and reduce transportation costs.

[0048] If the prefabricated box beam is large, steel plates can be used. Although they are bulky and heavy, they offer greater structural stability, are less prone to deformation, and ensure a regular surface. Furthermore, the steel plates can be drilled with multiple screw holes, which not only maintains structural stability but also facilitates installation of the support assembly 100 according to different design requirements.

[0049] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a box girder prefabricated component production and construction mold, on which a second upper support 151 on the side away from the web formwork 220 of the box girder prefabricated component production and construction mold is rotatably connected to a stop block 153 for supporting the side formwork 240, and an angle adjustment mechanism is provided between the stop block 153 and the second upper support 151.

[0050] The second upper support 151 of the box beam prefabricated component production and construction mold in the embodiment of the present application is rotatably connected to a stopper 153 for supporting the side formwork 240 , and an angle adjustment mechanism is provided between the stopper 153 and the second upper support 151 .

[0051] During specific implementation, the stop block 153 is used to support the side template 240. The stop block 153 and the side template 240 can be connected by bolts. An angle adjustment mechanism is provided between the stop block 153 and the second upper support 151. Rotating the stop block 153 can adjust the angle formed by the side template 240 and the wing template 230 to meet the installation requirements of different specifications.

[0052] It should be noted that the angle adjustment mechanism can specifically be a connecting shaft 154 and a compression sleeve 155 threadedly connected to both ends of the connecting shaft 154. The stop block 153 and the side template 240 are rotatably connected through the connecting shaft 154. When the stop block 153 and the side template 240 form a suitable angle, the compression sleeve 155 is twisted to squeeze the stop block 153 and the side template 240 against each other, thereby positioning the stop block 153.

[0053] In some alternative embodiments: See Figures 1 to 5 As shown, the embodiment of the present application provides a box girder prefabricated component production and construction mold, and a third hydraulic cylinder 160 for connecting and supporting the web template 220 is hinged on the base 110 of the box girder prefabricated component production and construction mold.

[0054] A third hydraulic cylinder 160 for connecting and supporting the web formwork 220 is hinged on the base 110 of the box beam prefabricated component production and construction mold in the embodiment of the present application.

[0055] During specific implementation, the extension length of the third hydraulic cylinder 160 is adjusted according to support requirements to provide stable support for the web template 220 to meet different installation requirements.

[0056] During use, the dimensions of the templates for each part of the box girder, the distribution of the base plate, and the telescopic length of each hydraulic cylinder are generated according to the bridge data designed by BIM. The construction workers first place the base plate according to the required distribution position, and then install each hydraulic cylinder on the base plate so that the length direction of each hydraulic cylinder points to the designed position, and then control the extension of each hydraulic cylinder to the designed position.

[0057] Then, the support for connection is installed at the designed position of the corresponding template, and then the corresponding template is hoisted above the hydraulic cylinder for installation and connection.

[0058] Finally, connect the connecting strips 260 to the gaps between the formwork panels, fix the support angle of the stoppers 153, and complete the box girder formwork assembly. To further enhance the formwork's strength, reinforcement plates can be secured between adjacent formwork panels using bolts or steel nails. Transverse clamps (not shown) can also be attached to the exterior of the side formwork panels 240. The interior formwork panels 250 can be constructed using existing internal molds, depending on design requirements.

[0059] It should be noted that by refining the structure of the various components of the outer mold support, this application can be divided into smaller modules compared to traditional outer mold supports. This saves space and reduces storage costs when stored centrally. Furthermore, it avoids the need for multiple large vehicles during transportation, reducing transportation costs. Assembly is simple, requiring only simple assembly according to the design drawings, requiring minimal worker skill. Furthermore, the design of additional connecting strips 260 reduces production complexity and ensures effective connections.

[0060] More importantly, the mold can be adjusted according to the designed box beam shape and size, and it is adjusted through hydraulic cylinders. Combined with the control program, the box beam shape data is imported into the computer, and the computer automatically controls the adjustment, thus ensuring that no matter how many sets of external mold supports are used, their positions can be unified, which is more accurate than manual adjustment.

[0061] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a box girder prefabricated component production and construction mold, wherein the web formwork 220 of the box girder prefabricated component production and construction mold is fixedly connected to a pad 221 for supporting the bottom formwork 210 at one end away from the wing formwork 230, and a connecting strip 260 for closing the casting gap is connected between adjacent two formworks among the bottom formwork 210, web formwork 220, wing formwork 230, and side formwork 240.

[0062] The web formwork 220 of the box girder prefabricated component production construction mold in the embodiment of the present application is fixedly connected to a pad 221 for supporting the bottom formwork 210 at one end away from the wing formwork 230, and a connecting strip 260 for closing the casting gap is connected between adjacent two formworks among the bottom formwork 210, web formwork 220, wing formwork 230, and side formwork 240.

[0063] During specific implementation, the bottom formwork 210 is laid on the pads 221 on both sides, and then the connecting strips 260 are installed in the casting gap formed between two adjacent formworks, thereby ensuring the casting quality.

[0064] In some alternative embodiments: See Figures 1 to 5 As shown, an embodiment of the present application provides a box girder prefabricated component production and construction mold, wherein the web formwork 220 and the wing formwork 230 of the box girder prefabricated component production and construction mold are both provided with a clamping block 261 on one side close to the connecting strip 260, and the two sides of the connecting strip 260 are provided with a clamping groove 262 for splicing the clamping block 261.

[0065] The web formwork 220 and the wing formwork 230 of the box girder prefabricated component production and construction mold in the embodiment of the present application are both provided with a clamping block 261 on one side close to the connecting strip 260 , and the connecting strip 260 is provided with a clamping groove 262 on both sides for splicing the clamping block 261 .

[0066] In practice, since the ends of the templates are flush, to adapt to various bridge structures, the gaps between the templates are connected by connecting strips 260. When the templates are made of wood, an adhesive such as glass glue can be injected into the gaps to ensure stable adhesion between the templates and connecting strips 260. When the templates are made of steel plates, protruding blocks 261 are provided at intervals between the connecting surfaces of the steel plates. Blocks 261 fit into slots 262 on connecting strips 260 to complete the splicing of the two templates.

[0067] It should be noted that the connecting strip 260 is made according to the shape of the cast box beam and is a connecting piece designed after the placement angle and specification design of the outer formwork are completed.

[0068] In some alternative embodiments: See Figures 1 to 5 As shown, the embodiment of the present application provides a box girder prefabricated component production and construction mold, and the connecting strip 260 of the box girder prefabricated component production and construction mold is a resin block.

[0069] The connecting strips 260 of the box beam prefabricated component production and construction mold in the embodiment of the present application are resin blocks.

[0070] During specific implementation, since the resin block has good processability, it is convenient to obtain the desired shape by cutting the long strip of resin block.
