Description

Technical Field

[0001] The present invention relates to the field of construction engineering technology, and in particular to an auxiliary clamping device for quickly positioning a steel skeleton; the device is used to solve the technical problem that vertical steel bars in concrete columns are easily deflected during vibration, thereby ensuring the quality and safety of reinforced concrete structures. Background Art

[0002] In modern construction projects, concrete columns serve as the primary vertical load-bearing components, and their construction quality is directly related to the safety and durability of the overall structure. According to the Code for Design of Concrete Structures (GB 50010-2010), the positional deviation of vertical reinforcement in concrete columns must not exceed 5mm; otherwise, the structure's load-bearing capacity will be severely impacted.

[0003] However, during the concrete pouring process, especially when vibrating the concrete to compact it, the reserved longitudinal reinforcement at the top of the concrete column is prone to shifting due to the vibration force. This shifting of the reinforcement can reduce the bond between the reinforcement and the concrete, thus affecting the overall performance of the reinforced concrete and even posing a safety hazard to the structure.

[0004] At present, the traditional method of steel bar positioning mainly adopts temporary brackets or binding fixation, but these methods have the following problems:

[0005] 1. Traditional fixing methods use wire tying or welding temporary brackets, which have low adjustment accuracy and often fail to meet regulatory requirements;

[0006] 2. Most existing positioning devices are disposable and cannot adapt to the positioning requirements of steel bars of different diameters, resulting in material waste;

[0007] 3. During the concrete vibration process, the steel bars are easily displaced due to the vibration force, and the average displacement can reach 8-12mm.

[0008] A search revealed that existing technologies, such as Patent No. CN201920358212.3, which discloses a rebar positioning device, suffer from problems such as a limited adjustment range and loose fixation. Patent No. CN202010584521.8, while offering improved adjustment capabilities, suffers from a complex structure and inconvenient operation. Therefore, there is an urgent need to develop an auxiliary clamping device for rapidly positioning rebar skeletons to address these technical issues. Summary of the Invention

[0009] The purpose of the present invention is to provide an auxiliary clamping device for quickly positioning a steel bar skeleton, so as to solve the problems of low steel bar positioning accuracy, poor adaptability, and loose fixation in the prior art, ensure the stable position of the vertical steel bars in the concrete column during the vibration process, and improve the construction quality and safety of the reinforced concrete structure.

[0010] The purpose of the present invention can be achieved through the following technical solutions:

[0020] As a further solution of the present invention: the vertical branch pipe is provided with a plurality of positioning sockets spaced from top to bottom, and one end of the horizontal branch pipe is inserted into the positioning socket; this design makes the connection between the vertical branch pipe and the horizontal branch pipe more flexible, and the height position of the horizontal branch pipe can be adjusted according to the actual height position of the vertical steel bar anti-deviation.

[0021] As a further solution of the present invention, the bottom end of the vertical branch pipe is plug-connected with the slot body on the stabilizing frame, which facilitates the installation and removal of the vertical branch pipe.

[0022] As a further solution of the present invention: the vertical branch pipes and the stabilizing frame are reinforced and connected by a diagonal bracing mechanism; this design ensures the stability of the supporting horizontal branch pipes, thereby ensuring the stability of the clamped vertical steel bars, and effectively preventing the steel bars from shifting during the vibration process.

[0023] As a further solution of the present invention: the diagonal support mechanism includes a diagonal support rod and a bottom support rod, one end of the bottom support rod is rotationally connected to the slot body, and the other end is rotationally connected to the inclined bottom end of the diagonal support rod, and the inclined top end of the diagonal support rod is fixedly connected to the pin connection part on the vertical branch pipe.

[0024] As a further solution of the present invention: the pin connection parts are arranged in an interval from top to bottom on the vertical branch pipe.

[0025] As a further solution of the present invention: the stabilizing frame, vertical branches, horizontal branches and clamping components are all made of carbon structural steel with a tensile strength of not less than 400 MPa; this material selection ensures the strength and durability of the equipment, enabling it to withstand various forces and vibrations during the construction process, thereby ensuring the safety of construction.

[0048] In this specific embodiment, Figure 2 As shown, the bottom end of the vertical branch pipe 200 is inserted and connected with the slot body 101 on the stable frame 100; the vertical branch pipe 200 and the stable frame 100 are reinforced by a diagonal support mechanism 500; the diagonal support mechanism 500 includes a diagonal support rod 501 and a bottom support rod 502, one end of the bottom support rod 502 is rotated to connect to the slot body 101, and the other end is rotated to connect to the inclined bottom end of the diagonal support rod 501, and the inclined top end of the diagonal support rod 501 is fixedly connected to the pin connection part 202 on the vertical branch pipe 200; the pin connection part 202 is located on the vertical branch pipe 200 and arranged at intervals from top to bottom.

[0049] During the assembly design process of the vertical branch pipe 200 and the stabilizing frame 100 of the present application, the connection between the two can be removed for easy disassembly and reuse. During assembly, as the installation height position of the horizontal branch pipe 300 changes, the diagonal bracing mechanism 500 can be used to reinforce the connection to ensure the stability of the horizontal branch pipe 300, thereby ensuring the stability of the clamped vertical steel bars.

[0050] In this specific embodiment, the stabilizing frame 100, vertical branch pipe 200, horizontal branch pipe 300 and clamping assembly 400 are all made of carbon structural steel with a tensile strength of not less than 400 MPa; the auxiliary clamping equipment of this application can be recycled, and the auxiliary support positioning vertical steel bars have a high application strength, ensuring the safety of construction.

[0051] The auxiliary clamping equipment of this application is used as follows:

[0052] Step 1: Install the stabilizing frame 100: First, place the stabilizing frame 100 at a predetermined location, ensuring that the stabilizing frame 100 is level and stable.

[0053] Step 2, installation of the vertical branch pipes 200: insert the bottom ends of the multiple vertical branch pipes 200 into the slot bodies 101 of the stabilizing frame 100 respectively to ensure that the vertical branch pipes 200 are firmly connected to the stabilizing frame 100.

[0054] Step 3, installation of the diagonal support mechanism 500: rotate one end of the bottom support rod 502 of the diagonal support mechanism 500 to connect to the slot body 101, and rotate the other end to connect to the inclined bottom end of the diagonal support rod 501, and then fix the inclined top end of the diagonal support rod 501 to the pin connection part 202 on the vertical branch pipe 200 to complete the installation of the diagonal support mechanism 500 and ensure the stability of the vertical branch pipe 200.

[0056] Step 5, installation of the clamping assembly 400: Slidingly sleeve the guide sleeve 404 of the clamping assembly 400 onto the transverse branch pipe 300, and adjust the position of the clamping assembly 400 by sliding along the length direction of the transverse branch pipe 300 according to the transverse position requirements of the steel bar.

[0057] Step 6: Place the vertical steel bar to be positioned into the clamping hole 401 of the clamping assembly 400 to ensure that the steel bar is stably clamped by the arc-shaped clamping groove 403.

[0058] Step 7: Lock the position of the clamping assembly 400 through the locking mechanism (such as the T-shaped locking piece 600) on the transverse branch pipe 300 to prevent the clamping assembly from sliding during the vibration process and ensure the stability of the steel bar positioning.

[0059] Step 8: After the steel bars are positioned, the concrete pouring operation is carried out. During the vibrating process, the steel bars are not easily deflected due to the stable clamping of the clamping assembly 400 and the fixing effect of the locking mechanism, thereby ensuring the construction quality of the reinforced concrete structure.
