Description

Technical Field

[0001] This utility model relates to the field of steel cage production technology, specifically to a well-adaptable tooling for binding, supporting and positioning box girder steel cages. Background Technology

[0002] Currently, box girders are generally prefabricated according to design requirements. The manufacturing process requires the prefabrication of steel reinforcement cages based on the shape and size requirements of the box girder. As the main load-bearing component of a bridge, the performance requirements for the box girder steel reinforcement cages are high. The main reinforcement bars of the box girder steel reinforcement cage can weigh several hundred kilograms and are more than ten meters long. The binding density of the main reinforcement bars is also high, which leads to difficulties in the routing and positioning of the main reinforcement bars during the binding process.

[0003] To address the difficulties in inserting and positioning the main reinforcement bars of the box girder steel cage, reference was made to... Figure 1 The existing solution involves prefabricating support and positioning fixtures for the main reinforcement bars based on the weaving parameters of the rebar cage. These fixtures are then spaced out on both sides of the rebar cage. This allows the main reinforcement bars to be supported and positioned after being inserted into the cage. However, the existing support and positioning fixtures are only suitable for rebar cages of the same specification. They cannot accommodate different types of rebar cages, such as when adjustments to the inclination of the cage's slope or the density of the main reinforcement bars are required. Furthermore, due to the characteristics of box girder construction and the differences in the construction environment, the requirements for rebar cages often vary. Therefore, the existing support and positioning fixtures cannot meet the usage requirements and urgently need further improvement.

[0004] Based on the above background, the inventors designed a highly adaptable tooling for binding, supporting and positioning box girder reinforcement cages, which solves at least one of the above problems, and thus, this application is hereby filed. Summary of the Invention

[0005] The purpose of this application is to provide a highly adaptable tooling for tying, supporting, and positioning box girder reinforcement cages, which solves the problem that existing tooling for tying, supporting, and positioning reinforcement cages cannot adapt to changes in the spacing and external dimensions of the reinforcement cages.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0007] This application provides a box girder reinforcement cage binding support and positioning fixture with good adaptability, including a first support positioning part and a second support positioning part fixedly connected, the first support positioning part being vertically arranged and the second support positioning part being inclinedly arranged;

[0008] It also includes several first positioning structures and second positioning structures, as well as support positioning rods mounted on the first positioning structures and second positioning structures:

[0009] The first positioning structure can be detachably installed on the first support positioning part and its installation position can be freely adjusted. The second positioning structure can be detachably installed on the second support positioning part and its installation position can be freely adjusted.

[0010] Optionally, the first support positioning part is provided with a first strip-shaped adjustment hole parallel to its axis, and the second support positioning part is provided with a second strip-shaped adjustment hole parallel to its axis.

[0011] The first positioning structure is detachably mounted on the first strip-shaped adjustment hole, and the second positioning structure is detachably mounted on the second strip-shaped adjustment hole.

[0012] Optionally, the first positioning structure includes a first positioning plate and a first positioning tube that are fixedly connected;

[0013] The first positioning plate is detachably mounted on the first strip-shaped adjustment hole by bolts;

[0014] With the first positioning plate installed, the first positioning tube is set perpendicular to the first strip-shaped adjustment hole;

[0015] One end of the support positioning rod passes through the first positioning tube and is inserted into the second positioning structure.

[0016] Optionally, the second positioning structure includes a second positioning plate and a second positioning tube that are fixedly connected.

[0017] The second positioning plate is detachably installed on the second strip-shaped adjustment hole by bolts;

[0018] With the second positioning plate installed, the second positioning tube is set perpendicular to the first strip-shaped adjustment hole.

[0019] Optionally, it also includes a connecting part, one end of which is fixed to the bottom side of the first support and positioning part, and the other end is fixed to the bottom of the second support and positioning part.

[0020] Optionally, the connecting part is an I-beam or a C-beam;

[0021] A reinforcing plate is also provided at the bottom of the connecting part. One end of the reinforcing plate is located near the middle of the connecting part, and the other end is fixed to the side of the first support positioning part.

[0022] Optionally, the top of the first support positioning part is further provided with a support surface for installing the reinforcing cage template.

[0023] Optionally, it also includes a mounting base and a mounting platform, with the mounting base fixedly connected to the bottom of the first support and positioning part;

[0024] The mounting base has slotted holes for mounting bolts, and the mounting base can be detachably mounted on the mounting platform by bolts.

[0026] Beneficial effects of the utility model:

[0027] I. This application, by setting up a first positioning structure and a second positioning structure, and supporting positioning rods installed on the first and second positioning structures, and the first and second positioning structures being detachably installed on the first and second supporting positioning parts respectively, allows the tooling of this application to adjust the spacing between adjacent first positioning structures and adjacent second positioning structures at any time when facing the binding requirements of rebar cages with different density requirements. This allows the spacing of the supporting positioning rods supporting the main bars of the rebar cage to be adjusted, thus enabling the use of the supporting positioning tooling of this application for rebar cages with different binding density requirements. This effectively solves the problem that existing rebar cage binding supporting positioning tooling cannot adapt to changes in the spacing and external dimensions of the rebar cage.

[0028] Second, the bottom of the first support positioning part of this application is fixed with an installation base, and the installation base can be fixedly connected to the installation platform by bolts. When this application needs to adapt to steel cages with different inclinations, the installation base can be equipped with shims, pads and other structures to make the first support positioning part and the second support positioning part tilt to a certain extent, thereby increasing the inclination angle of the second support positioning part, so as to adapt to and meet more types of steel cages and improve the adaptability of the support positioning fixture of this application.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.

[0034] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "longitudinal", "lateral", "horizontal", "inner", "outer", "front", "rear", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this 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 this utility model.

[0035] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "have," "install," "connect," and "connect" 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 this utility model based on the specific circumstances.

[0036] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] like Figure 1 As shown, in the prior art, the frame of the support and positioning fixture is an integral frame 1. The frame 1 is provided with two strip-shaped mounting holes 101, so that the frame 1 can be installed on the jig for binding the rebar cage through the two strip-shaped mounting holes 101. The extension rod 11 on it can play a supporting and positioning role for the insertion of the main reinforcement of the rebar cage. However, since the position of the extension rod 11 is fixed after the frame 1 is fixed, the support and positioning fixture in the prior art has poor adaptability and cannot meet the requirements for the insertion of the main reinforcement of the rebar cage for other binding requirements.

[0038] Therefore, as Figure 2 and Figure 3 As shown in the figure, the box girder reinforcement cage binding support and positioning tooling provided in this embodiment includes a first support positioning part 21 and a second support positioning part 22 fixedly connected. The first support positioning part 21 is arranged vertically and the second support positioning part 22 is arranged at an inclination.

[0039] It also includes several first positioning structures and second positioning structures, as well as support positioning rods mounted on the first positioning structures and second positioning structures:

[0040] The first positioning structure can be detachably installed on the first support positioning part 21 and its installation position can be freely adjusted. The second positioning structure can be detachably installed on the second support positioning part 22 and its installation position can be freely adjusted.

[0041] This embodiment, by setting a first positioning structure and a second positioning structure, and supporting positioning rods installed on the first and second positioning structures, and the first and second positioning structures being detachably installed on the first supporting positioning part 21 and the second supporting positioning part 22 respectively, allows the tooling of this application to adjust the spacing between adjacent first positioning structures and adjacent second positioning structures at any time when facing the requirements for binding rebar cages with different density requirements. This allows the spacing of the supporting positioning rods supporting the main reinforcement of the rebar cage to be adjusted, thus enabling the use of the supporting positioning tooling of this application for rebar cages with different binding density requirements. This effectively solves the problem that existing rebar cage binding supporting positioning tooling cannot adapt to changes in the density requirements of the main reinforcement of the rebar cage.

[0042] Specifically, in this embodiment, the first support positioning part 21 is provided with a first strip-shaped adjustment hole 211 parallel to its axis, and the second support positioning part 22 is provided with a second strip-shaped adjustment hole parallel to its axis.

[0043] The first positioning structure is detachably mounted on the first strip-shaped adjustment hole 211, and the second positioning structure is detachably mounted on the second strip-shaped adjustment hole.

[0044] By setting the first strip-shaped adjustment hole 211 and the second strip-shaped adjustment hole, the first positioning structure and the second positioning structure can be easily adjusted in position.

[0045] Specifically, in this embodiment, the first positioning structure includes a first positioning plate and a first positioning tube that are fixedly connected;

[0046] The first positioning plate is detachably mounted on the first strip-shaped adjustment hole 211 by bolts;

[0047] With the first positioning plate installed, the first positioning tube is set perpendicular to the first strip-shaped adjustment hole 211;

[0048] One end of the support positioning rod passes through the first positioning tube and is inserted into the second positioning structure. In this embodiment, the diameter of the first positioning tube is larger than the diameter of the support positioning rod, so that the support positioning rod can easily pass through the first positioning tube.

[0049] In this embodiment, a pull handle is provided at the end of the support positioning rod away from the second positioning structure to facilitate pulling it out of the second positioning structure.

[0050] Specifically, in this embodiment, the second positioning structure includes a second positioning plate and a second positioning tube that are fixedly connected;

[0051] The second positioning plate is detachably installed on the second strip-shaped adjustment hole by bolts;

[0052] With the second positioning plate installed, the second positioning tube is set perpendicular to the first strip-shaped adjustment hole 211. In this embodiment, the axes of the second positioning tube and the first positioning tube are set parallel to each other, so that the support positioning rod can be easily inserted into the second positioning tube after passing through the first positioning tube, thereby enabling the support positioning rod to support and position the insertion of the main reinforcement of the steel cage.

[0053] Specifically, in this embodiment, a connecting part is also included. One end of the connecting part is fixed to the bottom side of the first support positioning part 21, and the other end is fixed to the bottom of the second support positioning part 22. The connecting part can improve the stability of the first support positioning part 21 and the second support positioning part 22.

[0054] Specifically, in this embodiment, the connecting part is an I-beam;

[0055] A reinforcing plate is also provided at the bottom of the connecting part. One end of the reinforcing plate is located near the middle of the connecting part, and the other end is fixed to the side of the first support and positioning part 21. The reinforcing plate can further improve the structural stability of the support and positioning fixture in this embodiment.

[0056] Specifically, in this embodiment, the top of the first support positioning part 21 is also provided with a support surface for installing the steel cage template, which facilitates the support of the steel cage template.

[0057] Specifically, in this embodiment, it also includes a mounting base and a mounting platform, with the mounting base fixedly connected to the bottom of the first support and positioning part 21;

[0058] The mounting base has slotted holes (not shown in the figure) for mounting bolts, and the mounting base is detachably mounted on the mounting platform by bolts.

[0059] In this embodiment, an installation base is fixed to the bottom of the first support positioning part 21, and the installation base can be fixedly connected to the installation platform by bolts. When it is necessary to adapt to steel cages with different slopes, the installation base can be equipped with a structure such as a shim or a pad, so that the first support positioning part 21 and the second support positioning part 22 are tilted to a certain extent, thereby increasing the tilt angle of the second support positioning part 22 to adapt to and meet more types of steel cages and improve the adaptability of the support positioning fixture of this application.

[0060] Specifically, both the first support positioning part 21 and the second support positioning part 22 are I-beams. Technicians can choose other structural components such as steel plates or C-shaped steel as needed, which will not be elaborated here.

[0061] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
