Description

Technical Field

[0001] The present invention relates to the field of construction equipment for building projects, and in particular to a column-type reinforcement cage main reinforcement fixing auxiliary device and a construction method thereof. Background Art

[0002] Pile foundations play a crucial role in engineering projects and are the fundamental guarantee for structural safety. Piles extend deep underground, transferring their own weight to the deep, solid soil or rock layers, providing stable vertical support for the structure. They require sufficient strength and rigidity. The steel cage is a crucial component of the pile foundation, significantly enhancing the pile's compressive, bending, and shear strengths. The precision of the steel cage, as well as the connection method and quality of the rebar, significantly impact the progress and quality of pile foundation construction.

[0003] At present, when making steel cages, workers first make reinforcement bars, and then mark the reinforcement bars according to the spacing of the main bars. When welding, they support the bars with their hands. As a result, the quality of the steel cage is greatly affected by human factors, and quality problems are very likely to occur. Moreover, when the length of the pile body is too large, the splicing of the upper and lower steel cages has high requirements on the spacing of the main bars of the steel cages, and problems such as splicing failure are prone to occur. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art and provide a column type reinforcement cage main reinforcement fixing auxiliary device and a construction method thereof.

[0005] The specific technical solutions are as follows: A column type reinforcement cage main reinforcement fixing auxiliary device, comprising: a main frame; At least one slide rail, the slide rail being fixedly disposed on the main frame and being used to provide a linear positioning reference; At least two caliper units, each of which can slide along the length direction of the slide rail and is provided with a first locking mechanism to detachably fix itself at a predetermined position on the slide rail; each caliper unit is provided with a groove for accommodating and preliminarily positioning the main reinforcement; and A second locking mechanism is provided on the caliper unit and is used for quickly pressing and finally fixing the main rib placed in the groove.

[0006] Optionally, scale lines or equidistantly distributed positioning holes for setting the distance between the caliper units are provided on the surface of the slide rail.

[0007] Optionally, the first locking mechanism of the caliper unit is a manual locking bolt or a locking handle.

[0008] Optionally, the caliper unit includes a slider slidably engaged with the slide rail, and a clamping arm fixedly connected to the slider, and the groove is provided on the clamping arm.

[0009] Optionally, the second locking mechanism is a spring-loaded caliper, which can quickly switch between a locking position for tightening the main rib and an unlocking position for releasing the main rib.

[0010] Optionally, the main frame is a portal frame with adjustable width, or a plurality of bases that can be independently fixed on a construction platform or the ground.

[0011] Optionally, the pin rod end of the elastically loaded caliper is an arc surface for fitting with the surface of the main rib.

[0012] Optionally, the groove on the clamping arm is configured as a V-shaped groove.

[0013] Optionally, the slider is configured as a nylon slider that matches the internal shape of the C-shaped slide rail.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) By combining a slide rail with precise scales or positioning holes with a lockable caliper unit, the setting of the main reinforcement spacing is transformed into a precise quantitative operation. The operator only needs to set the caliper position according to the drawing to ensure that all main reinforcements are equidistant and evenly distributed. The main reinforcement spacing error can be stably controlled within ±2mm, which is far better than the error level of more than ±10mm in traditional manual binding, fundamentally ensuring the geometric dimensional accuracy and stress performance of the steel cage; (2) The present invention simplifies the complex positioning work into three steps: "setting-placement-locking". In particular, the application of quick locking mechanisms such as elastically loaded calipers reduces the final fixing time of a single main reinforcement from several minutes in traditional binding to 10-15 seconds. According to calculations, the use of this device can increase the forming efficiency of the main reinforcement skeleton of the entire steel cage by more than 50%, effectively shortening the construction period. (3) The standardized and modular operation process is intuitive and easy to understand, which greatly reduces the skill requirements for operators. Ordinary workers only need simple training to master the operation essentials, and do not need to have proficient welding or measurement skills; (4) By freely increasing or decreasing the number of caliper units and adjusting their positions on the slide rail, this device can flexibly adapt to the processing requirements of various column-type steel cages with different diameters (for example, from Φ800mm to Φ2500mm) and different numbers of main bars (for example, from 10 to 40). It has strong versatility and avoids the waste of repeatedly making special templates for steel cages of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0020] Example 1 This embodiment provides a column type reinforcement cage main reinforcement fixing auxiliary device, referring to Figures 1 to 3 , mainly including: A main frame 1; At least one slide rail 2, which is fixed on the main frame 1 and is used to provide a linear positioning reference; At least two caliper units 3, each caliper unit 3 can slide along the length direction of the slide rail 2 and is provided with a first locking mechanism to detachably fix itself to a predetermined position on the slide rail 2; the caliper unit 3 is provided with a groove for accommodating and preliminarily positioning the main reinforcement; and A second locking mechanism is provided on the caliper unit 3 and is used to quickly compress and finally fix the main rib placed in the groove.

[0021] The main frame 1 is welded from two columns and two upper and lower beams, and has a stable structure. A C-shaped slide rail 2 is fixedly welded on the inner side of the upper and lower beams. The surface of the slide rail 2 is engraved with scale lines in millimeters for precise positioning; multiple caliper units 3 with the same structure are installed on the upper and lower pairs of slide rails 2.

[0022] Each caliper unit 3 comprises: A nylon slider 31 that matches the inner shape of the C-shaped slide rail 2; A clamping arm 32 fixed to the slider 31 by bolts, a V-shaped groove 33 is formed on the horizontal portion of the clamping arm 32 for accommodating the main reinforcement; A locking handle 34 that passes through the slider 31 and can press the slider 31 against the inner wall of the slide rail 2, serving as a first locking mechanism; and A spring-loaded caliper 5 mounted above the clamping arm 32 serves as a second locking mechanism. The end of the pin rod of the latch is an arc surface that can fit well with the surface of the main reinforcement.

[0023] The usage and operation process of the device of this embodiment are as follows: Step 1, preparation stage: according to the design drawing of the steel cage to be processed, determine its diameter, the type and number N of main bars, and install N caliper units 3 on the upper and lower slide rails 2 respectively; Step 2: Setting the spacing: Loosen the first locking mechanism (i.e., locking handle 34) of all caliper units 3. Based on the main rib spacing D calculated from the drawing and referring to the scale lines on the slide rail 2, accurately move the upper and lower corresponding caliper units 3 one by one to the predetermined positions; for example, the first caliper is at the 0 scale, the second at the D scale, the third at the 2D scale, and so on. After positioning, pull down the locking handle 34 to securely position the caliper units 3. Step 3: Place and secure the main reinforcement: Place a main reinforcement horizontally in the V-shaped groove 33 of all the caliper units 3. Then, the operator pulls the two ends of the second locking mechanism (i.e., the spring-loaded caliper 5) on each caliper unit 3 together until it is locked. At this point, the main reinforcement is firmly pressed into the V-shaped groove 33 by the pin. Repeat this step until all N main reinforcements are secured, forming a stable single-layer main reinforcement skeleton. Step 4. Subsequent operations: After the main reinforcement frame is fixed, the spiral stirrups can be wound, welded or tied; since the main reinforcement has been firmly fixed, subsequent operations will not cause its position to change. After the operation is completed, pull all the ends of the elastically loaded calipers 5 away to unlock, release the locking handle 34, and you can easily remove the formed steel cage.

[0024] Example 2 This embodiment is similar to the first embodiment in terms of basic structure and principle, with the main difference being the design of the main frame 1. The main frame 1 of this embodiment is not a fixed portal frame, but rather is composed of multiple independent bases that can be fixed to a construction platform or the ground. Each base is mounted with a small section of slide rail 2, and adjacent slide rails 2 are secured together by slide rail 2 latches. During use, these bases are arranged in a circular or polygonal shape on a flat surface according to the diameter requirements of the steel cage, and then the caliper units 3 are mounted on each section of slide rail 2. This design sacrifices some integrity but greatly improves the device's portability and site adaptability, making it particularly suitable for applications where space is limited or where it needs to be used in conjunction with large-scale seam welding equipment.

[0025] The above are only preferred embodiments of the present invention and do not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
