Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and specifically to an auxiliary device for cutting and dismantling concrete structural beams. Background Technology

[0002] Social progress and development have led to an increase in building renovation and reinforcement projects. Renovation projects involve a large amount of structural demolition, among which the demolition of beam components is particularly difficult.

[0003] In current building reinforcement and renovation projects, since the renovation work is mostly carried out indoors, the use of conventional hoisting and support machinery is greatly restricted indoors. If scaffolding is erected to support the concrete beams that need to be demolished, not only will the construction time be long, but it will also consume a lot of manpower and resources. Summary of the Invention

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide an auxiliary device for cutting and dismantling concrete structural beams, thereby solving the problem of troublesome indoor concrete beam dismantling in the prior art.

[0005] To achieve the above objectives, this utility model provides an auxiliary device for cutting and demolishing concrete structural beams, used to assist in the cutting and demolition of indoor concrete structural beams. The auxiliary device includes: Two vertically parallel frames are provided, each frame having casters on both sides of its bottom for movement. At least two horizontally parallel connecting rods are located between the two frames, and the two ends of the connecting rods are detachably connected to the two frames by connecting pins. At least two horizontally parallel crossbeams are located at the top of the two frames, and the two ends of the crossbeams are detachably connected to the top of the two frames respectively. At least two electric hoists are respectively installed on the crossbeam; The frame, connecting rods, and crossbeams are connected to form a three-dimensional stable frame structure, and in conjunction with the electric hoist, they facilitate the cutting and dismantling of concrete structural beams.

[0006] By adopting this technical solution, the frame, connecting rods, crossbeams, and electric hoists work together to form a three-dimensional stable frame structure with quick assembly and disassembly capabilities and hoisting functions. This allows for auxiliary hoisting of concrete structural beams after indoor assembly, before cutting and dismantling them, eliminating the need for other support work before the concrete structural beams are cut and dismantled. At the same time, the concrete structural beams can be directly transferred after cutting and dismantling with the help of casters. This undoubtedly simplifies the indoor concrete structural beam cutting and dismantling process, reduces construction difficulty, and improves construction efficiency.

[0007] Furthermore, the rack includes: At least two uprights; At least two horizontal bars are located between two adjacent vertical bars; the two ends of each horizontal bar are detachably connected to the two vertical bars by connecting pins. A diagonal tie rod is located between two adjacent horizontal bars, and its two ends are detachably connected to the two adjacent vertical bars respectively by means of connecting pins that connect the horizontal bars and the vertical bars at corresponding positions; The uprights, horizontal bars, and diagonal braces are connected together to form a planar stable frame structure.

[0008] By adopting this technical solution, a triangular stable structure is formed by uprights, horizontal bars, and diagonal braces, which greatly enhances the rigidity and stability of the scaffold itself, thereby preventing instability or lateral overturning during hoisting and ensuring construction safety. All members are connected by connecting pins, which is simple in construction, quick to install, and does not require welding. This method conforms to the concept of prefabricated construction, significantly improves erection efficiency, and shortens construction preparation time.

[0009] Furthermore, the top of the upright has a insertion groove; Both ends of the crossbeam have insertion posts at their bottom; The plug and the slot are plugged in to achieve a detachable connection.

[0010] By adopting this technical solution, the combination of plug-in columns and plug-in slots is a simple, intuitive and effective connection method. It can quickly realize the installation and positioning of crossbeams, and can also transfer loads, ensuring smooth force flow. This connection method does not require complicated tools or permanent fixation, which makes it easy to make fine adjustments to the frame during construction and also facilitates quick disassembly after the work is completed, improving the flexibility and turnover rate of the device.

[0011] Furthermore, the caster is a brakeable caster with a locking function.

[0012] By adopting this technical solution, the brakeable casters can be locked after the auxiliary device moves to the predetermined position, turning the moving mechanism into a fixed support, effectively preventing the device from moving unexpectedly during hoisting and cutting, which is a key guarantee for construction safety; it achieves the ideal state of "flexible when moving and stable when working", perfectly solving the contradiction of traditional scaffolding being unable to move and large equipment being inconvenient to move.

[0013] Furthermore, the crossbeam is an I-beam; The auxiliary device also includes a moving component, which includes a drive wheel mounted on the electric hoist. The drive wheel travels along the lower flange of the crossbeam to achieve horizontal movement of the electric hoist.

[0014] By adopting this technical solution and using I-beams as crossbeams, in addition to their high structural strength, the electric hoist can also be provided with a natural track for movement. The electric hoist can move along the crossbeam by the drive wheels moving on the lower flange of the I-beam. In addition to being able to stably lift concrete structural beams at different angles, the position can also be adjusted to avoid the problem of the concrete structural beams causing damage to the device itself after cutting and demolition.

[0015] Compared with the prior art, this utility model has the following advantages: The frame, connecting rods, crossbeams, and electric hoists work together to form a three-dimensional stable frame structure with quick assembly and disassembly capabilities and hoisting functions. This allows for auxiliary hoisting of concrete structural beams after indoor assembly, before cutting and dismantling them, eliminating the need for other support work before the concrete structural beams are cut and dismantled. At the same time, the casters enable the direct transfer of the concrete structural beams after cutting and dismantling, which undoubtedly simplifies the indoor concrete structural beam cutting and dismantling process, reduces construction difficulty, and improves construction efficiency.
