Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an auxiliary device suitable for tying beam reinforcement bars. Background Technology

[0002] In building construction, rebar tying is a crucial step, especially in the construction of precast beams and slabs, where efficient and stable securing of the rebar is essential. Currently, many construction sites use traditional rebar erection aids, which are mostly single-use and suffer from structural instability, cumbersome installation, and limited reusability, leading to increased labor costs, extended construction periods, and resource waste. Therefore, there is an urgent need for a rebar tying aid that provides stable support and is reusable. However, traditional rebar tying methods have limitations. For example, large-section beams require specific space, and the construction process is complex, making it difficult for workers to perform precise and effective rebar tying within the confined space enclosed by the beam formwork. Utility Model Content

[0003] The purpose of this utility model is to provide a reusable beam rebar tying auxiliary device to solve the technical problems of traditional beam rebar tying auxiliary devices having unreasonable structural design, lack of flexibility, inability to meet the rebar tying needs of beams of different heights, and lack of stability and reusability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] A reusable beam rebar tying auxiliary device includes a support frame and a crossbeam; there are two support frames arranged parallel to each other in the transverse direction; each support frame includes a base and a mounting frame; the base is placed horizontally on the floor slab; the mounting frame is connected to the top of the base; the crossbeam is mounted on the mounting frames on both sides, and the height of the crossbeam on the mounting frame is adjustable; rebar positioning structures are provided at intervals on the crossbeam to ensure that the rebar does not shift during the tying process; an intelligent monitoring system is provided on the support frame and / or the crossbeam, and the accuracy, stability and safety of the rebar tying process are ensured through real-time monitoring and feedback of the intelligent monitoring system.

[0006] Preferably, the base includes a lower supporting steel bar; the lower supporting steel bar has a planar geometry; a rubber anti-slip pad is installed at the bottom of the lower supporting steel bar to increase the friction with the floor slab; the lower supporting steel bar is detachably connected to the mounting frame or can be folded.

[0007] Preferably, the mounting bracket includes uprights and horizontal bars; there are two uprights, arranged in parallel and spaced apart; vertical slots are correspondingly provided on the two uprights; there are at least two horizontal bars, vertically adjustable and connected between the two uprights, and the horizontal bars are fixed to the uprights on the corresponding side by double nuts; scale markings are added to the uprights to clearly show the installation height of the horizontal bars.

[0008] Preferably, the bottom of both ends of the crossbeam is provided with a slot; the slot is engaged with the corresponding horizontal bar; the top of the horizontal bar is provided with blind holes at intervals; and crossbeam positioning components are adjustablely connected to the blind holes at the top of the horizontal bar on both sides of the crossbeam.

[0009] Preferably, the intelligent monitoring system includes a sensor group, a data transmission system, a control system, and an early warning system; the sensor group includes a force sensor, a position sensor, a tilt sensor, and a temperature and humidity sensor; the force sensor is arranged on the crossbeam at the position corresponding to the rebar to be tied and on the mounting frame at the position corresponding to the crossbeam overlap; the position sensor is arranged on the crossbeam near the position of the rebar to be tied, and is used to monitor the displacement of the rebar tying device; the tilt sensor is installed on the mounting frame to monitor whether the mounting frame tilts; the temperature and humidity sensor is installed on the support frame to monitor the temperature and humidity changes of the construction environment.

[0010] Preferably, the crossbeam comprises multiple steel rods, each steel rod being 20cm to 30cm long, and adjacent steel rods are detachably connected.

[0011] Compared with the prior art, the present invention has the following features and beneficial effects.

[0012] 1. The strip-shaped holes, scale markings, and double-nut fixing method on the uprights of this utility model allow for precise adjustment of the beam height to the millimeter level (error ≤ 2mm), ensuring that the position of the reinforcing bars meets design requirements and avoiding errors from manual measurement. Simultaneously, the positioning components on the beam cooperate with the blind holes on the horizontal bars, combined with locking slots, to prevent the reinforcing bars from shifting due to vibration or external forces during the binding process, ensuring uniform stress distribution on the beam.

[0013] 2. The lower support steel bars and connecting cylinders of this application adopt the plug-in + bolt connection method. The installation time of a single set of devices is ≤5 minutes, and the volume is reduced by 60% after disassembly, which is convenient for transportation to the next section for reuse, and the overall construction efficiency is improved by more than 30%.

[0014] 3. The segmented hinged steel rod design of this utility model (20~30cm / segment) supports bending into an arc or zigzag shape, which can match the binding requirements of irregular beams (such as arc beams and zigzag beams) and reduce the cost of customized tools.

[0015] 4. The sensor array of this utility model monitors the force on the reinforcing bars (force sensor), the tilt of the mounting bracket (tilt angle ≤ 1° alarm), and the ambient temperature and humidity (humidity > 85% triggers an early warning) in real time. The data is uploaded to the cloud or local terminal via a data transmission system, enabling early intervention against risks. The temperature and humidity sensor monitors environmental conditions in real time (e.g., a high temperature alarm threshold of 50℃), and with the addition of an anti-rust coating, it can be used stably in harsh environments ranging from -20℃ to 60℃ and with humidity ≤ 95%.

[0016] 5. From an economic perspective, this utility model allows for multiple reuses, saving on engineering machinery costs. From a construction efficiency perspective, the new auxiliary device reduces the time workers spend on rebar installation and tying. Disassembly requires only simple manual manipulation of the beams, accelerating construction progress, shortening the construction period, and indirectly reducing project costs. From a safety perspective, it reduces the impact of inaccurate or uneven reinforcement in beams and slabs on the overall stability of the building. Furthermore, the separate upper and lower structural design facilitates transportation and on-site assembly, improving construction efficiency. The structure is stable and reusable, effectively reducing construction costs. The materials have high strength and durability, adapting to complex construction environments.

[0024] When the lower supporting steel bar 1.1.1 is detachably connected to the mounting frame 1.2, the base 1.1 also includes a connecting cylinder 1.1.2; there are two connecting cylinders 1.1.2, which are connected at intervals to the top of the lower supporting steel bar 1.1.1; the lower end of the mounting frame 1.2 is inserted into the connecting cylinder 1.1.2 and is detachably connected to the connecting cylinder 1.1.2 by bolts.

[0025] When the lower supporting steel bar 1.1.1 and the mounting frame 1.2 are foldably connected, the lower end of the mounting frame 1.2 is bent to both sides to form a horizontal connecting section, and the horizontal connecting section is connected to the lower supporting steel bar 1.1.1 by a hinge.

[0026] In this embodiment, the mounting bracket 1.2 includes two uprights 1.2.1 and two horizontal bars 1.2.2. The uprights 1.2.1 are arranged parallel to each other and spaced apart.
