Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a controller for vertical high-level rebar installation and its construction method. Background Technology

[0002] In the renovation, reinforcement, and secondary structure construction of reinforced concrete structures, vertical rebar installation is often required at the bottom of poured beams and slabs. Traditional construction methods typically rely on scaffolding or aerial work platforms, placing workers at heights. These methods have significant drawbacks: First, working at heights poses serious safety risks such as falls and falling objects, and scaffolding erection and dismantling are time-consuming, labor-intensive, and costly. Second, workers in a suspended and unstable position find it difficult to accurately control the verticality and insertion depth of the rebar. Practice shows that with traditional methods, the rebar depth qualification rate is less than 85%, easily leading to insufficient anchorage length, rebar misalignment, and uneven colloid distribution, severely affecting the load-bearing capacity and structural safety of the rebar joints.

[0003] While existing technologies offer some auxiliary tools for ground or lateral rebar installation, there is a general lack of dedicated, systematic solutions for the specific condition of "vertical high-position" rebar installation. Construction workers lack effective force transmission and precise guidance methods, and construction quality still relies excessively on individual experience and skills.

[0004] Therefore, there is an urgent need for a specialized device and method that can fundamentally avoid the risks of working at heights, enable safe operation by a single person on the ground, and ensure the verticality and depth accuracy of rebar installation through mechanization and visualization. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a controller for vertical high-level rebar installation and its construction method, which enables construction workers to stand on the ground or a stable floor slab to complete the vertical rebar installation work on the beams and slabs above their heads, eliminating the risks of working at heights.

[0006] To achieve this technical objective, the present invention adopts the following solution: In a first aspect, the present invention provides a controller for vertical high-level rebar installation, including a vertically fixed rebar installation steel sleeve for installing and guiding the rebar. An auxiliary vertical installation thickening pad is fixedly provided at the bottom end of the vertically fixed rebar installation steel sleeve. A vertical auxiliary observation bubble meter is provided on the vertically fixed rebar installation steel sleeve. At least one handheld vertical adjustment handle is fixedly provided on the side wall of the vertically fixed rebar installation steel sleeve.

[0007] Furthermore, the vertically fixed steel sleeve for rebar installation is a high-strength metal round pipe (preferably galvanized steel pipe), with an inner diameter 2-10mm larger than the diameter of the rebar, maintaining a certain gap to ensure the rebar can pass freely while preventing excessive sway. The length of the vertically fixed steel sleeve is greater than the lap length of the rebar. The vertically fixed steel sleeve can be designed with a fixed length or a detachable connection structure, depending on the specific circumstances.

[0008] Furthermore, the auxiliary vertical installation thickened pad is made of high-strength material and is welded and fixed to the bottom of the vertical fixing steel sleeve to form a sealed bottom structure and increase the bottom force-bearing area, which can ensure its stability during operation.

[0009] Furthermore, the handheld vertical adjustment handle is welded and fixed with high-strength round steel, providing the operator with a stable and labor-saving grip point for handheld operation and vertical deviation adjustment of the rebar.

[0010] Furthermore, the vertical auxiliary observation bubble meter is used to observe verticality during construction, facilitating timely adjustments.

[0011] Secondly, the present invention provides a construction method using the aforementioned vertical high-level rebar anchor controller, comprising the following steps: S1. Install the cut rebar into the vertical fixed rebar sleeve. The surface of the rebar is marked with a rebar depth marking line to indicate the rebar depth. S2. Inject anchoring adhesive into the surface of the rebar insertion section and into the anchoring holes of the concrete component. S3. The operator holds the vertical adjustment handle to control the alignment of the end of the rebar with the anchor hole. S4. Tap the auxiliary vertical installation thickened pad plate to slowly send the rebar into the anchoring hole until the anchoring depth mark line reaches the preset position. S5. During the feeding process, observe the vertical auxiliary bubble meter. If a verticality deviation occurs, adjust it in time by holding the vertical adjustment handle. S6. After the implantation is completed, remove the vertically fixed steel sleeve from the rebar and use it for the implantation of the next rebar.

[0012] Furthermore, the length of the reinforcing bar is greater than or equal to the sum of the lap length and the anchoring depth.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: High safety: It transforms high-altitude operations into ground or stable platform operations, eliminating the need for climbing and fundamentally eliminating the safety risks associated with falls from heights and scaffolding, which aligns with the core concept of safe production.

[0014] Improved construction precision: Through the mechanical constraints of the rigid sleeve and the real-time visual feedback of the bubble meter, a closed-loop control of the verticality of the rebar is achieved, with a precision far exceeding that of human eye estimation; by aligning the pre-set depth marking line on the rebar with the concrete surface, the implantation depth can be precisely controlled to ensure that the anchorage length meets the design requirements.

[0015] Efficiency improvement: The main work steps can be completed by one person; it saves a lot of time, materials and labor costs for erecting and dismantling scaffolding, and significantly improves overall construction efficiency. Attached Figure Description

During the feeding process, observe the vertical auxiliary bubble meter 5. If a verticality deviation occurs, adjust it in time by holding the vertical adjustment handle 4. S6. After the implantation is completed, the vertically fixed steel sleeve 1 is removed from the steel rebar 3 and used for the implantation of the next steel rebar 3.
