Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an auxiliary support and method for installing reinforcing bars. Background Technology

[0002] In the construction of large industrial and civil buildings, especially circular or annular cylindrical structures such as silos, grain silos, and storage silos, the binding and installation of the reinforcing steel frame is a crucial process. With increasingly optimized engineering designs, the size and structural complexity of silos are constantly increasing, resulting in very limited space on the construction site, especially at the rebar work area. Traditional rebar construction methods typically involve transporting pre-fabricated reinforcing steel bars to the ground near the work area using tower cranes or truck cranes, where construction workers then handle, position, and bind each bar individually. However, these traditional methods have the following significant drawbacks in specific construction scenarios such as silos: Low construction efficiency and high labor intensity: The steel bars need to be moved multiple times, and the handling from the ground to the installation position depends entirely on manual labor. Inside the narrow silo, it is inconvenient for workers to operate and they consume a lot of physical strength, resulting in slow installation speed. Installation accuracy is difficult to guarantee: Due to the large length and weight of steel bars (especially threaded steel bars), problems such as positional deviation and uneven spacing are very likely to occur during manual handling and placement. Construction personnel need to repeatedly adjust the position of the steel bars, which is not only time-consuming, but also makes it difficult to ensure that key parameters such as steel bar spacing and protective layer thickness meet the design requirements, thus affecting the quality of the project. Poor adaptability: There is a lack of specialized auxiliary tools that can be flexibly adjusted to adapt to site size and steel bar specifications for silos of different diameters or steel bars of different lengths. Traditional methods are often "one tool for one method", resulting in low reuse rate.

[0003] Therefore, there is an urgent need for a special auxiliary device and method that can improve the efficiency and accuracy of steel bar installation, reduce labor intensity, and adapt to complex construction conditions. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an auxiliary support and method for rebar installation, which can effectively improve construction speed, flexibly adjust the length of rebar, and save installation time.

[0005] The technical solution adopted by this invention to solve its technical problem is: A rebar installation auxiliary support includes several main supports, a telescopic adjustment mechanism disposed between two adjacent main supports for changing the spacing between adjacent main supports and adjusting the overall length of the auxiliary support; the telescopic adjustment mechanism is disposed on the main supports for adjusting the support height of the main supports; and rebar positioning slots are spaced apart on the top of the main supports for supporting and constraining the lateral displacement of the rebars.

[0006] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the height and length of the auxiliary support are both adjustable, enabling it to quickly adapt to the needs of different engineering structures, different construction stages, and different sizes of reinforcing bars. It also allows for the reuse of the auxiliary support, making it highly versatile. The top reinforcing bar positioning groove not only serves to prevent rolling but also provides the possibility for precise fine-tuning of the threaded steel bars, effectively ensuring the spacing between reinforcing bars, the lap length, and the thickness of the protective layer, thus fundamentally improving the quality of the reinforcing steel project.

[0007] As a preferred embodiment, a further technical solution of the present invention is: Preferably, the main support includes a base, columns and a crossbeam. Columns are provided at both ends of the base, and a crossbeam is provided between the two columns. The steel bar positioning slots are opened at the top of the measuring element and are spaced apart along the length of the measuring element.

[0008] Preferably, the height adjustment mechanism includes a telescopic rod and a pin. The telescopic rod is slidably placed on the upper end of the column. Several adjustment holes are spaced apart on the telescopic rod. A positioning hole is provided on the column. The pin passes through the positioning hole and the adjustment hole to fix the telescopic rod to the column.

[0009] This invention also discloses a construction method for an auxiliary support for rebar installation, comprising the following steps: Step S1: Arrange the auxiliary support for steel reinforcement installation at the construction site, adjust the telescopic adjustment mechanism according to the construction requirements to set the total length of the auxiliary support, and adjust the height adjustment mechanism to set the working height of the auxiliary support, and then lock it. Step S2: Hoist the processed steel bars to the top of the auxiliary support and place them in the steel bar positioning slot; Step S3: Construction workers take the reinforcing bars from the auxiliary support for installation, and when in place, they apply rotation or axial thrust to the reinforcing bars and use the cooperation between the reinforcing bars and the positioning slots to fine-tune the installation position. Step S4: After the current construction section is completed, disassemble the telescopic adjustment mechanism and complete the transfer of the auxiliary support.

[0010] This method provides a dedicated, nearby, and orderly temporary storage point for steel bars, enabling "immediate use upon hoisting." It avoids the need for manual long-distance and repeated handling of steel bars, freeing workers from heavy physical labor and allowing them to focus on binding operations, thereby significantly accelerating the construction progress.

[0012] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0013] like Figure 1 , Figure 2 As shown, a rebar installation auxiliary support includes several main supports 1, a telescopic adjustment mechanism 2, which is set between two adjacent main supports 1 to change the spacing between adjacent main supports 1 and adjust the overall length of the auxiliary support; a height adjustment mechanism 3, which is set on the main supports 1 to adjust the support height of the main supports 1; and rebar positioning slots 4, which are spaced at the top of the main supports 1 to support and constrain the lateral displacement of the rebars 5.

[0014] Preferably, the main support 1 includes a base 101, columns 102 and crossbeams 103. Columns 102 are respectively provided at both ends of the base 101, and a crossbeam 103 is provided between the two columns 102. The steel bar positioning slots 4 are opened at the top of the crossbeams 103 and are spaced apart along the measuring length direction.

[0015] In this embodiment, the telescopic adjustment structure adopts the existing linkage telescopic structure. The linkage telescopic structure is installed on the side of the column 102 to assist in the overall length of the support. This part is an existing structure, and the specific structure will not be described in detail here.

[0016] The height adjustment mechanism 3 consists of a telescopic rod 301 and a pin 302. The telescopic rod 301 is slidably positioned on the upper end of the column 102. Several adjustment holes 303 are spaced apart on the telescopic rod 301. A positioning hole 304 is provided on the column 102. The pin 302 passes through the positioning hole 304 and the adjustment holes 303 to fix the telescopic rod 301 to the column 102. By changing the adjustment holes 303 at different positions, the height of the main support 1 can be adjusted.

[0017] Based on the above structure, a construction method for an auxiliary support for rebar installation is carried out according to the following steps: Step S1: Arrange the steel reinforcement installation auxiliary support at the construction site, adjust the telescopic adjustment mechanism 2 according to the construction requirements to set the total length of the auxiliary support, and adjust the height adjustment mechanism 3 to set the working height of the auxiliary support, and then lock it.

[0018] Step S2: Hoist the processed steel bar 5 to the top of the auxiliary support and place it in the steel bar positioning slot 4.

[0019] Step S3: Construction workers take the reinforcing bars from the auxiliary support for installation. When in place, they apply rotational or axial thrust to the reinforcing bars 5 and use the cooperation between the reinforcing bars and the reinforcing bar positioning slots 4 to fine-tune the installation position.

[0020] Step S4: After the current construction section is completed, disassemble the telescopic adjustment mechanism 2 and complete the transfer of the auxiliary support.

[0021] The auxiliary support of this invention provides a dedicated and orderly temporary storage point for reinforcing bars, realizing "ready to use after hoisting", avoiding long-distance and repeated manual handling of reinforcing bars and reducing labor intensity; the top reinforcing bar positioning slot not only plays a role in limiting and preventing rolling, but also makes it possible to make precise fine adjustments to the threaded steel bars. The axial position can be finely adjusted through a simple rotation action, effectively ensuring the accuracy of the reinforcing bar spacing, lap length and protective layer thickness, fundamentally improving the quality of reinforcing steel engineering. The adjustable height and extendable length of the support system allow it to quickly adapt to the needs of different engineering structures, construction stages, and steel reinforcement sizes. A single unit can be reused in multiple projects or multiple locations within the same project, making it highly versatile.

[0022] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
