Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and in particular to a simple auxiliary tool for installing steel bars in cast-in-place concrete structural beams. Background Technology

[0002] Cast-in-place concrete construction is the process of building structural components on-site by performing a series of procedures, including formwork erection, rebar tying, pouring, vibration, and curing, to achieve the desired structural form. It results in structures with good overall integrity, excellent seismic performance, and the ability to adapt to complex shapes, and is widely used in building engineering.

[0003] Currently, in the construction of cast-in-place concrete structures, the installation of steel reinforcement in concrete structural beams is generally carried out after the beam and slab formwork is installed. Temporary portal steel pipe support frames are then erected along the beam span for the installation of structural beam steel reinforcement. After the beam steel reinforcement is installed, the construction workers dismantle the temporary steel pipe supports one by one, allowing the beam steel reinforcement skeleton to fall freely into the beam groove. This can easily lead to deformation of the stirrups and loosening of the binding wires, affecting the installation quality of the structural beam steel reinforcement. At the same time, the erection of temporary steel pipe support frames requires finding suitable short steel pipes to ensure the requirements of different beam heights; otherwise, the steel pipes must be cut, which is inconvenient for management and reuse. Utility Model Content

[0004] The purpose of this utility model is to provide a simple auxiliary tool for installing reinforcing bars in cast-in-place concrete structural beams. It aims to solve the technical problems in the prior art regarding the arrangement of reinforcing bars before binding, support during the binding process, and positioning after binding of reinforcing bars in cast-in-place concrete structural beams. It avoids deformation of the reinforcing bar skeleton, loosening of binding wires, and the need to find suitable short steel pipes to meet the requirements of different beam heights when setting up temporary steel pipe support frames. Otherwise, the steel pipes need to be cut, which is inconvenient for management and reuse.

[0005] To achieve the above objectives, this utility model employs a simple auxiliary tool for installing reinforcing bars in cast-in-place concrete structural beams, comprising a beam channel reinforcement structure and an installation mechanism. The installation mechanism includes a steel plate base, a channel steel column, a stabilizing component, a rotating shaft bracket, an adjusting component, a wire rope, a roller assembly, a crossbeam bracket, a crossbeam, and a third pin. The steel plate base is detachably connected to the beam channel reinforcement structure and is located above it. The channel steel column is fixedly connected to the base and is located above it. The stabilizing component is fixedly connected to the channel steel column and is located outside the channel steel column. The rotating shaft bracket is connected to the channel steel column... The column is fixedly connected and located above the channel steel column. The adjusting assembly is detachably connected to the rotating shaft bracket and located above the rotating shaft bracket. One end of the wire rope is fixedly connected to the adjusting assembly and located below the adjusting assembly.

The crossarm bracket is fixedly connected to the roller assembly and located on the side of the roller assembly away from the channel steel column. The crossarm is detachably connected to the crossarm bracket and located above the crossarm bracket. The third pin is detachably connected to the crossarm bracket and passes through the crossarm.

[0006] The stabilizing component includes a hanger and a stabilizing hook. The hanger is fixedly connected to the channel steel column and is located on the outside of the channel steel column. The stabilizing hook is detachably connected to the hanger and passes through the hanger.

In practical use, the steel plate base is placed at a suitable location on the beam channel reinforcement structure. The stabilizing component enhances the stability of the channel steel column installation. The adjusting component is placed above the rotating shaft bracket. Based on the dimensions of the beam channel reinforcement structure, the position of the crossbeam within the crossbeam bracket bracket is adjusted. After adjustment, the crossbeam is fixed to the crossbeam bracket bracket using the third pin. The height of the crossbeam is adjusted by pulling the steel wire rope using the adjusting component. The roller assembly rolls within the channel steel column to assist in adjustment, allowing the crossbeam to assist construction workers in installing the structural beam reinforcing bars.

[0020] In this embodiment, construction workers place the steel plate base 2 at a suitable location on the beam channel reinforcement structure 1 according to the span of the structural beam. The stabilizing component is used to improve the stability of the installation of the channel steel column 3. The channel steel column 3 fixes the rotating shaft support 6, and the channel steel column 3 is made of channel steel with its opening facing inward, serving as a track for the roller assembly 13 to adjust up and down. The adjusting component is placed above the rotating shaft support 6, and the bottom of the rotating shaft support 6 has a pre-reserved pin hole.
