Description

Technical Field

[0001] This utility model relates to the technical field of steel cage processing in building engineering, and in particular to a processing platform for irregular-shaped steel cages for diaphragm walls. Background Technology

[0002] A diaphragm wall is a foundation engineering project where a trenching machine is used on the ground to excavate a narrow, deep trench along the perimeter of the deep excavation project, with mud slurry as the wall support. After cleaning the trench, a steel cage is suspended inside, and then underwater concrete is poured using the tremie pipe method to form a unit trench segment. This process is repeated segment by segment to build a continuous reinforced concrete wall underground, serving as a water-cutting, seepage-proof, load-bearing, and water-retaining structure.

[0003] During the on-site construction of diaphragm walls, most of the reinforcing cages are ordinary straight cages, but it is unavoidable to encounter irregularly shaped cages with corners. This type of cage often fails to fit into the trench due to angular deviations during cage fabrication, resulting in a mismatch between the cage angle and the trench angle.

[0004] The temporary operating platform erected during the fabrication of irregular-shaped steel reinforcement cages for diaphragm walls using existing technology not only cannot accurately and quickly adjust the required angle, but also cannot be reused, resulting in slow construction speed and high construction costs. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a processing platform for irregular-shaped steel cages for diaphragm walls, which can improve the accuracy of steel cage adjustment angle, is easy to operate, can be reused, and has high safety.

[0006] To achieve the above objectives, this utility model provides a diaphragm wall irregular-shaped steel cage processing platform, including a platform as a foundation, a first steel truss horizontally placed on the platform via steel columns, and a second steel truss rotatably connected to the first steel truss via steel hinges; an angle adjustment mechanism is provided between the bottom of the second steel truss and the platform for adjusting the rotation angle of the second steel truss relative to the first steel truss; rounded corner rulers are provided at both ends of the first steel truss for displaying the rotation angle of the second steel truss.

[0007] Preferably, the rounded corner ruler includes a disc panel fixedly connected to the first steel truss and a pointer rotatably connected to the disc panel; the disc panel has scale lines engraved on its circumference for displaying angles, and the pointer for indicating the scale lines is fixedly connected to the end of the second steel truss, and the pointer rotates together with the second steel truss.

[0008] Furthermore, the angle adjustment mechanism includes a steel connecting plate fixed on the platform, two steel uprights vertically installed on the steel connecting plate and arranged in parallel, and an electric hydraulic jack rotatably connected between the two steel uprights. The end of the telescopic rod of the electric hydraulic jack is rotatably connected to the second steel truss.

[0009] Preferably, the base of the electric hydraulic jack is provided with steel uprights at both ends and a rotating shaft for connecting the jack. The steel uprights are provided with through holes through which the rotating shaft for connecting the jack passes. The end of the rotating shaft for connecting the jack extending out of the steel uprights is provided with a first pin to prevent the electric hydraulic jack from sliding relative to the steel uprights.

[0010] Furthermore, the telescopic rod of the electric hydraulic jack is provided with a rotating shaft for connecting the jack and the steel truss. The second steel truss is provided with a through hole through which the rotating shaft for connecting the jack and the steel truss passes. The end of the rotating shaft for connecting the jack and the steel truss extending out of the through hole is provided with a second pin for preventing the electric hydraulic jack from sliding relative to the second steel truss.

[0011] Furthermore, both the first steel truss and the second steel truss include a transversely arranged main steel truss beam and a longitudinally arranged secondary steel truss beam connected to the main steel truss beam. The main steel truss beam and the secondary steel truss beam form a rectangular grid structure.

[0012] In summary, compared with the prior art, the diaphragm wall irregular-shaped steel cage processing platform of this utility model has at least the following beneficial effects:

[0013] 1. Steel hinges are used to connect the trusses, allowing the angle to be adjusted freely using an electric hydraulic jack, and the required angle can be precisely controlled using a rounded square.

[0014] 2. It helps save time, as it only needs to be installed once to meet all angle requirements on site and avoids instability of the steel cage.

[0015] 3. This device provides a safe and stable construction platform through the support of steel columns and jacks, avoiding instability caused by the unstable support of temporary operating platforms during construction. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See below. Figures 1-3 This invention provides a detailed description of the diaphragm wall irregular-shaped steel cage processing platform.

[0023] This utility model's diaphragm wall irregular-shaped steel cage processing platform mainly consists of a foundation platform, a rounded corner ruler 1, steel hinges 2, steel columns 3, a first steel truss 10, a second steel truss 20, and an angle adjustment mechanism 6. The first steel truss 10 is horizontally placed on the platform via the steel columns 3, and the second steel truss 20 is rotatably connected to the first steel truss 10 via the steel hinges 2. The angle adjustment mechanism 6 is located between the bottom of the second steel truss 20 and the platform, used to adjust the rotation angle of the second steel truss 20 relative to the first steel truss 10. The rounded corner ruler 1 is installed at both ends of the first steel truss 10 to display the rotation angle of the second steel truss 20.

[0024] This invention utilizes an angle adjustment mechanism 6 to switch between straight and irregularly shaped reinforcing cages, and precisely controls the required angle by observing the scale on a rounded ruler 1 fixed to both sides of the steel truss. The rounded ruler 1 includes a circular panel fixedly connected to the first steel truss 10 and a pointer rotatably connected to the circular panel. The circular panel of the rounded ruler 1 has circumferentially engraved scale lines for displaying angles. The pointer, used to indicate the scale lines, is fixedly connected to the end of the second steel truss 20. The pointer rotates with the second steel truss 20. When the second steel truss 20 and the first steel truss 10 are both horizontal, the arrow of the pointer points to the 0 mark of the scale line.

[0025] The angle adjustment mechanism 6 includes a steel connecting plate 601 fixed on the platform, two steel uprights 604 vertically installed on the steel connecting plate 601 and arranged in parallel, and an electric hydraulic jack 605 rotatably connected between the two steel uprights 604. The end of the telescopic rod of the electric hydraulic jack 605 is rotatably connected to the second steel truss 20.

[0026] The electric hydraulic jack 605 has steel plates at both ends of its base and a rotating shaft 603 for connecting the jack. The steel plates 604 have through holes through which the rotating shaft 603 passes. The end of the rotating shaft 603 extending out of the steel plates 604 is provided with a first pin 602 to prevent the electric hydraulic jack 605 from sliding relative to the steel plates 604.

[0027] The telescopic rod of the electric hydraulic jack 605 is provided with a rotating shaft 606 for connecting the jack and the steel truss. The second steel truss 20 is provided with a through hole for the rotating shaft 606 to pass through. The end of the rotating shaft 606 extending out of the through hole is provided with a second pin 607 to prevent the electric hydraulic jack 605 from sliding relative to the second steel truss 20.

[0028] The first steel truss 10 and the second steel truss 20 of this utility model both include a transversely arranged main steel truss beam 4 and a longitudinally arranged secondary steel truss beam 5 connected to the main steel truss beam 4. The main steel truss beam 4 and the secondary steel truss beam 5 form a rectangular grid structure.

[0029] The construction of irregular-shaped steel reinforcement cages for diaphragm walls utilizes the device of this invention to quickly adjust the steel truss to the required angle, facilitating the fabrication of the reinforcement cage. The specific implementation steps are as follows:

[0030] Step 1: Submit a processing plan to the factory to process steel columns 3, main steel truss beams 4, secondary steel truss beams 5, steel connecting plates 601, and steel uprights 604 from steel plates.

[0031] Step 2: Connect the steel column 3 to the platform (or concrete surface) with bolts.

[0032] Step 3: Weld the first steel truss 10, which consists of the main steel truss beam 4 and the secondary steel truss beam 5, onto the steel column 3.

[0033] Step 4: The second steel truss 20, which is welded together from the main steel truss beam 4 and the secondary steel truss beam 5, is hoisted by a crane and rotatably connected to the first steel truss 10 via steel hinge 2.

[0034] Step 5: Fix the steel connecting plate 601 to the platform with bolts.

[0035] Step 6: Weld the steel upright plate 604 to the steel connecting plate 601.

[0036] Step 7: Connect the electric hydraulic jack 605 to the steel upright plate 604 via the rotating shaft 603 connecting the steel upright plate and the jack, and insert the first pin 602 to fix it, so as to prevent the electric hydraulic jack 605 from sliding relative to the steel upright plate 604.

[0037] Step 8: Connect the telescopic rod of the electric hydraulic jack 605 to the second steel truss 20 through the jack-to-steel truss connecting shaft 606 and insert the second pin 607 to fix it, so as to prevent the electric hydraulic jack 605 from sliding relative to the second steel truss 20.

[0038] After completion, as follows Figure 1 As shown, the next step of construction will then proceed.

[0039] Step 9: Adjust the angle between the two steel trusses using the electric hydraulic jack 605, and display the angle to be adjusted using the rounded corner ruler 1.
