Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a steel cage binding frame. Background Technology

[0002] The piers of an overpass are important components that support the superstructure of the overpass. Their main function is to effectively transfer the load from the superstructure to the foundation, thereby ensuring the stability and safety of the overpass.

[0003] Due to the complex structure of overpasses, the loads borne by the piers at different locations vary. For example, the horizontal forces and torques on the piers will differ at curves, ramp connections, and near bridge expansion joints; the vertical loads borne by the piers at the mid-span and supports of the bridge will also vary. Taking into account extreme differences, this results in slight variations in the structural dimensions of the piers, leading to a wide variety of pier types.

[0004] In a typical construction process, the steel bars are first processed into semi-finished products. Then, scaffolding is erected on the construction site, and cranes are used to lift and transport the semi-finished steel bars. Workers then tie them on-site or assemble them using scaffolding. Subsequent steps include installing formwork, adjusting the protective layer, and finally pouring concrete to form the overpass piers.

[0005] However, traditional construction methods often suffer from problems due to the lack of standardized references when manually tying rebar cages on-site. These issues include deviations in the verticality of single-strand splices of main bars, non-standard cross-sectional dimensions of the rebar cage, poor horizontality of stirrups, and uneven spacing. Consequently, it becomes difficult to effectively control the concrete cover, making it challenging to ensure that the thickness of the concrete cover meets the overall project's requirements for the concrete cover qualification rate after pouring. Furthermore, workers face significant safety risks due to prolonged exposure to heights during rebar tying. Moreover, this construction method requires significant crane usage time, resulting in low work efficiency. Utility Model Content

[0006] The purpose of this utility model is to provide a rebar cage binding frame to solve the technical problems of low qualification rate, low efficiency and poor safety of the existing construction method of manually binding rebar cages on site.

[0007] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0008] A steel cage binding frame, comprising:

[0009] A plurality of tire frame units arranged at intervals along a first straight line, wherein the tire frame unit includes:

[0010] A support assembly includes a support beam and a support column. The support column is detachably mounted on the support beam. There are two support columns, which are spaced apart along the length of the support beam.

[0011] The positioning plate is detachably connected to the supporting column. Multiple positioning slots are spaced apart along its own extension direction. Each positioning slot of the frame unit corresponds to a positioning slot. Each steel bar can pass through the corresponding positioning slot on each frame unit in sequence. Multiple steel bars can be arranged to form a steel cage.

[0012] Preferably, a limiting circular groove is formed by a recess on the inner wall of the positioning groove, and the limiting circular grooves in the corresponding positioning grooves are coaxially arranged, and the reinforcing bar can pass through the limiting circular groove.

[0013] Preferably, there are four positioning plates, namely two vertical plates and two horizontal plates. The vertical plates extend parallel to the supporting columns, and each vertical plate is connected to one supporting column. The horizontal plates extend parallel to the supporting beams, and each horizontal plate is connected to two supporting columns at both ends. The four positioning plates are arranged in a rectangular pattern.

[0014] Preferably, the cross plate includes a central portion located in the middle part and side portions located on both sides of the central portion along its own length direction. The central portion is recessed inward to form a groove, and the side portions protrude outward in an arc shape.

[0015] Preferably, the positioning plate has a first through hole, and the side wall of the supporting column has a corresponding second through hole. The first locking bolt can pass through the first through hole and the second through hole in sequence and be locked by the first locking nut.

[0016] Preferably, the supporting beam has a third through hole, and the bottom wall of the supporting column has a corresponding fourth through hole. The second locking bolt can pass through the third through hole and the fourth through hole in sequence and be locked by the second locking nut.

[0017] Preferably, the steel cage binding frame further includes a construction platform, which is located on one side of the frame unit and extends along a first straight line. A guardrail is provided on the side of the construction platform away from the frame unit.

[0018] Preferably, the height of the construction platform is adjustable.

[0019] Preferably, the construction platform is provided with a moving channel at both ends, and the moving channel connects the construction platform to the ground.

[0020] Preferably, there are two construction platforms, which are symmetrically arranged on both sides of the frame unit.

[0021] The beneficial effects of this utility model are:

[0022] The reinforcing cage binding jig proposed in this utility model is used as follows: First, select an appropriate number of jig units according to the specifications and dimensions of the prefabricated reinforcing cage, install the support columns on the support beams, and connect the positioning plates to the support columns. Then, pass the first reinforcing bar through the corresponding positioning slot on each jig unit in sequence, and so on, passing multiple reinforcing bars through the positioning slots according to the design requirements. This ensures that the reinforcing bars are accurately arranged to form a preliminary reinforcing cage structure under the constraint of the positioning slots. After all the reinforcing bars are arranged, they are bound and reinforced with stirrups to form a sturdy reinforcing cage. After the reinforcing cage is bound, remove the positioning plates and support columns, and remove the prefabricated reinforcing cage from the jig, ready for subsequent construction operations.

[0023] Throughout its use, the supporting beams and columns work together to provide a stable foundation for the entire frame. Multiple positioning slots spaced along the extension direction of the positioning plate, in conjunction with each frame unit, precisely define the position of the reinforcing bars, ensuring that each bar accurately passes through its corresponding slot. This results in prefabricated reinforcing cages with standardized dimensions, improving the pass rate of the concrete cover for the pier reinforcement. Furthermore, the detachable design of the supporting columns and beams, and the positioning plates and columns, allows for flexible adjustment of the frame components according to different installation locations and pier cross-sectional shapes. In practical applications, the frame can be easily disassembled and reassembled to accommodate the prefabrication needs of various types of pier reinforcement. This facilitates transportation and storage, reduces costs, enhances the versatility and applicability of the frame, and improves production efficiency and resource utilization. Standardized binding frames reduce the uncertainty of manual operations, lessen reliance on worker experience and skills, avoid the risks of workers operating at heights, and improve the consistency and reliability of reinforcing cage fabrication.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] See Figures 1 to 4 The steel cage binding frame provided in this embodiment of the utility model includes a plurality of frame units 10 arranged at intervals along a first straight line. Each frame unit 10 includes a support component 1 and a positioning plate 2. The support component 1 includes a support beam 11 and a support column 12. The support column 12 is detachably mounted on the support beam 11. There are two support columns 12, which are arranged at intervals along the length of the support beam 11. The positioning plate 2 is detachably connected to the support column 12. The positioning plate 2 has a plurality of positioning grooves 23 spaced apart along its own extension direction. The positioning grooves 23 of each frame unit 10 correspond one-to-one. Each steel bar 100 can pass through the corresponding positioning groove 23 on each frame unit 10 in sequence. The plurality of steel bars 100 can be arranged to form a steel cage.

[0039] The reinforcing cage binding jig proposed in this utility model is used as follows: First, select an appropriate number of jig units 10 according to the specifications and dimensions of the prefabricated reinforcing cage, and install the support columns 12 on the support beams 11. Then, connect the positioning plates 2 to the support columns 12. Next, pass the first reinforcing bar 100 through the corresponding positioning grooves 23 on each jig unit 10 in sequence. This process is repeated, passing multiple reinforcing bars 100 through the positioning grooves 23 according to the design requirements, so that the reinforcing bars 100 are accurately arranged to form a preliminary reinforcing cage structure under the constraint of the positioning grooves 23. After all the reinforcing bars 100 are arranged, they are bound and reinforced with stirrups to form a sturdy reinforcing cage. After the reinforcing cage is bound, remove the positioning plates 2 and support columns 12, and remove the prefabricated reinforcing cage from the jig, ready for subsequent construction operations.

[0040] Throughout its use, the supporting beam 11 and supporting column 12 work together to provide a stable foundation for the entire frame. Multiple positioning slots 23, spaced apart along their extension direction on the positioning plate 2, precisely define the position of the reinforcing bars 100 by cooperating with each frame unit 10. This ensures that each reinforcing bar 100 accurately passes through its corresponding positioning slot 23 on each frame unit 10, resulting in prefabricated reinforcing cages with standard dimensions and improving the pass rate of the pier reinforcement protective layer. Furthermore, the detachable design of the supporting column 12 and supporting beam 11, and the positioning plate 2 and supporting column 12, allows for flexible adjustment of the frame components according to different installation positions and pier cross-sectional shapes. In practical applications, the frame can be easily disassembled and reassembled to adapt to the prefabrication requirements of various types of pier reinforcement. This facilitates transportation and storage, reduces costs, enhances the versatility and applicability of the frame, and improves production efficiency and resource utilization. Standardized binding frames reduce the uncertainty of manual operations, decrease reliance on worker experience and skills, avoid the risks of workers working at heights, and improve the consistency and reliability of rebar cage fabrication.

[0041] Hereinafter, the first straight line direction is defined as horizontal and extends perpendicular to the length direction of the supporting beam 11. For the convenience of describing in conjunction with the accompanying drawings, the direction described below is the direction shown in the accompanying drawings, but is not limited thereto.

[0042] The specific structure of the steel cage binding frame is described below.

[0043] Regarding the connection method between the supporting beam 11 and the supporting column 12, in this embodiment, the supporting beam 11 has a third through hole 111, and the supporting column 12 has a corresponding fourth through hole 122 on its bottom wall. When the supporting column 12 needs to be installed on the supporting beam 11, the second locking bolt can pass through the third through hole 111 on the supporting beam 11 and the fourth through hole 122 on the bottom wall of the supporting column 12 in sequence. Subsequently, it is locked by the cooperation of the second locking nut and the second locking bolt. The third through hole 111 and the fourth through hole 122 provide an accurate through position for the second locking bolt, ensuring the accuracy and stability of the connection. The combination of the second locking bolt and the second locking nut can apply sufficient tightening force to firmly fix the supporting column 12 to the supporting beam 11.

[0044] The installation and disassembly process is convenient and quick. When disassembly is required, simply loosen the second locking nut and remove the second locking bolt to separate the support column 12 from the support beam 11.

[0045] In other embodiments, the support beam 11 and the support column 12 can also be connected by a pin, a snap-fit, etc., which is not limited here, as long as the two can be detachably connected.

[0046] After the supporting beam 11 and supporting column 12 are installed, the positioning plate 2 needs to be installed on the supporting column 12 to facilitate the subsequent positioning and installation of the reinforcing bar 100. Specifically, the positioning plate 2 has a first through hole 24, and the supporting column 12 has a corresponding second through hole 121 on its side wall. The first locking bolt can pass through the first through hole 24 and the second through hole 121 in sequence and be locked by the first locking nut.

[0047] Specifically, four positioning plates 2 are provided: two vertical plates 21 and two horizontal plates 22. The vertical plates 21 extend parallel to the supporting columns 12, and each vertical plate 21 is connected to one supporting column 12. The horizontal plates 22 extend parallel to the supporting beams 11, and each end of each horizontal plate 22 is connected to two supporting columns 12. The four positioning plates 2 are arranged in a rectangular pattern, thus forming a regular frame structure, providing accurate boundaries and guidance for the positioning of the reinforcing bars 100 and the binding of the reinforcing cage. This also enhances the stability and reliability of the entire frame, and helps to improve the efficiency and quality of reinforcing cage binding.

[0048] Furthermore, the horizontal plate 22 includes a central portion 221 located in the middle and side portions 222 located on both sides of the central portion 221 along its length. The central portion 221 is recessed inward to form a groove with a specific shape and depth. This recessed design can reduce the weight of the horizontal plate 22 to a certain extent, while providing some clearance for the arrangement of reinforcing bars or enhancing the structural stability of the horizontal plate 22. The side portions 222 protrude outward in an arc shape. This arc shape gives the side portions 222 a certain curvature, structurally increasing the strength and rigidity of the horizontal plate 22, enabling it to better withstand external forces. Moreover, the arc shape provides a smoother appearance and reduces stress concentration on the side portions 222.

[0049] Furthermore, a limiting circular groove 231 is recessed on the inner wall of the positioning groove 23, and the limiting circular grooves 231 in corresponding positioning grooves 23 are coaxially arranged, allowing the reinforcing bar 100 to pass through the limiting circular groove 231. When multiple jig units 10 are arranged, the limiting circular grooves 231 in the corresponding positioning grooves 23 can form a continuous, coaxial channel. When binding the reinforcing cage, the reinforcing bar 100 can pass through the limiting circular groove 231, making the position of the reinforcing bar 100 in the positioning groove 23 more accurate and stable. The limiting circular groove 231 provides additional limiting and guiding for the reinforcing bar 100, preventing unnecessary movement or shaking of the reinforcing bar 100 in the positioning groove 23, and improving the stability of the reinforcing bar 100 installation.

[0050] After the support component 1 and positioning plate 2 are fixed, operators need to insert, tie, and fix the reinforcing bars 100. To facilitate operation, the reinforcing cage tying frame also includes a construction platform 3. The construction platform 3 is located on one side of the frame unit 10 and extends along the first straight line. A guardrail 31 is installed on the side of the construction platform 3 away from the frame unit 10. The construction platform 3 provides a stable and spacious operating area for operators. The guardrail 31 is used to prevent operators from accidentally falling from the edge of the construction platform 3, providing safety for operators working on the platform.

[0051] Specifically, the construction platform 3 has access channels 32 at both ends, connecting it to the ground. These access channels 32 are in the form of stairs. The stairs consist of multiple steps, each with the same height and width, to facilitate movement for workers. Handrails provide sufficient support and protection for the workers. One end of the stairs is securely connected to the construction platform 3, while the other end extends smoothly to the ground. The part in contact with the ground is equipped with anti-slip devices to prevent slipping during use. When workers need to reach the construction platform 3 for rebar cage tying work, they can safely and conveniently access it from the ground via the stairs. After completing the work, they can return to the ground via the stairs.

[0052] In other embodiments, the moving channel 32 may also be configured as a ramp, a lifting platform, etc., which are not limited here.

[0053] Furthermore, there are two construction platforms 3, which are symmetrically arranged on both sides of the frame unit 10. The symmetrical design of the construction platforms 3 allows construction personnel to approach the frame unit 10 from different directions, making it convenient to operate from multiple angles and improving the convenience and efficiency of the work.

[0054] Furthermore, to enhance the adaptability of the construction platform 3, its height is adjustable. Specifically, the bottom of the construction platform 3 is equipped with multiple retractable support legs. Each support leg consists of two nested tubular components. The inner tubular component has multiple evenly distributed positioning holes, while the outer tubular component has corresponding pins. By inserting the pins into the positioning holes at different positions, the length of the support leg can be adjusted, thereby achieving the adjustment of the height of the construction platform 3.

[0055] For example, when rebar cage tying work needs to be performed at a higher position, the pin can be pulled out, the support leg extended, and then the pin inserted into the corresponding positioning hole for fixation, thereby raising the construction platform 3. When the working position is lower, the operation is reversed, the support leg shortened, and the height of the construction platform 3 lowered.

[0056] In other embodiments, the construction platform 3 can also be height adjusted by hydraulic jacks, electric screw adjusters or pneumatic lifting devices, which will not be elaborated here.

[0057] The following describes the specific process of using the steel cage binding frame.

[0058] First, select a suitable site according to construction requirements, and assemble multiple frame units 10 in sequence along a first straight line. In each frame unit 10, the support column 12 is detachably installed on the support beam 11 by the second locking bolt and the second locking nut, and two support columns 12 are arranged at intervals along the length of the support beam 11.

[0059] Then, the four positioning plates 2 are installed. Two vertical plates 21 extend parallel to the support columns 12, and each vertical plate 21 is connected to a support column 12 by a first locking bolt and a first locking nut. Two horizontal plates 22 extend parallel to the support beams 11, and the two ends of each horizontal plate 22 are connected to two support columns 12 by a first locking bolt and a first locking nut, respectively. The four positioning plates 2 are arranged in a rectangular pattern.

[0060] Next, the construction workers reach the construction platform 3 through the moving channel 32. On the construction platform 3, the steel bars 100 are passed through the corresponding positioning grooves 23 on each frame unit 10 and the limiting circular grooves 231 formed by the recesses on the inner wall of the positioning grooves 23. The multiple steel bars 100 are arranged to form the preliminary shape of the steel cage.

[0061] Finally, the steel bars 100 are tied and the stirrups are fixed to complete the fabrication of the steel cage, making it a sturdy steel cage.

[0062] After the steel reinforcement cage is tied, the positioning plate 2 and the support column 12 are removed, and the prefabricated steel reinforcement cage is taken off the jig to prepare for subsequent construction operations.

[0063] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
