Description

Technical Field

[0001] This utility model relates to the field of assembling the main reinforcement hanger of a square thin-walled pier, specifically to an assembly jig for the main reinforcement hanger of a square thin-walled pier. Background Technology

[0002] In the construction of mountain highways, bridge piers often face the challenges of large height and large pier column dimensions. When constructing square hollow piers, the main reinforcement is extended, the installation work is extensive and frequent, the high-altitude work time is long, and the safety risks in the process of hoisting and positioning the reinforcement are high. Traditional construction methods (traditional installation one pier or one section at a time) cannot meet the requirements of speed, safety and quality control. The traditional installation method has the following problems: (1) a large amount of high-altitude work, with high safety risks; (2) the risk of overturning; (3) the quality of the reinforcement protective layer is difficult to control. Utility Model Content

[0003] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a square thin-walled pier main reinforcement hanger assembly frame.

[0004] This utility model is implemented as follows: a square thin-walled pier main reinforcement hanger assembly frame is constructed, characterized in that: the assembly frame includes a load-bearing frame composed of angle steel, the bottom of the load-bearing frame is a steel plate, and step plates and guardrails are installed sequentially on the load-bearing frame, which are connected by bolts or welding to form an integral whole including a three-layer working platform, and the middle part of the whole is the overall installation and lifting area of ​​the main reinforcement hanger.

[0005] The present invention has the following advantages: the installation frame is located on the ground, and all work is completed on the ground, reducing construction safety risks; the steel bars are fixed by the hangers on the installation frame, preventing the steel bars from tilting.

[0006] Meanwhile, an innovative overall lifting and installation method was adopted: the main reinforcing bars are first positioned and connected on the ground using square piers, and then lifted and installed as a whole using a tower crane. This method greatly improves the speed of reinforcing bar installation and effectively prevents the overturning of reinforcing bars during construction. Compared with the traditional method of installing one bar or section at a time, it reduces the working time of workers at height, lowers safety hazards, and reduces the labor intensity of construction workers.

[0007] Improved positioning accuracy: The settings in this application enable a qualitative leap in the installation accuracy of the pier reinforcement bars, ensuring the accuracy of the reinforcement bar installation position and laying a good foundation for subsequent construction procedures.

[0008] Improved construction efficiency and standardized operations: Reinforcing bars are installed using scaffolding and rebar assembly frames, followed by overall hoisting and installation. The main reinforcing bars on the four sides of the pier can be fabricated and installed separately, allowing for parallel or continuous construction. This significantly reduces rebar installation time to one-quarter of the original time. Furthermore, this construction method facilitates standardized, regulated, and factory-like operations, helping to save time and labor costs, and improving the overall project efficiency.

[0011] The components include: 1. load-bearing frame; 2. steel plate; 3. footboard; 4. guardrail; and 5. main reinforcement hanger. Detailed Implementation

[0012] The following will be combined with the appendix Figures 1-2 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0013] This utility model provides a square thin-walled pier main reinforcement hanger assembly frame, such as... Figures 1-2 As shown, it can be implemented in the following manner: The assembly frame includes a load-bearing frame 1 composed of angle steel, the bottom of the load-bearing frame 1 is a steel plate 2, and a stepping plate 3 and a guardrail 4 are installed on the load-bearing frame 1 in sequence. The frame is connected by bolts or welding to form an integral three-layer working platform. The middle part of the integral is the overall installation and lifting area of ​​the main rib hanger 5.

[0014] The assembly frame of this application is mainly composed of materials such as structural steel, guardrails, step plates, steel plates, and bolts. The main load-bearing frame is composed of 10-angle steel, followed by the installation of step plates and guardrails. The entire load-bearing skeleton of the frame is connected using welding technology. The frame is constructed layer by layer, ultimately forming an installation frame containing three working platforms to assist in the installation of the square pier reinforcement. Four hangers with pre-assembled main reinforcement bars are bolted together on the frame to form a whole, which is then lifted to the installation area for overall installation.

[0015] The application of this frame is explained below:

[0016] (1) Site leveling and hardening: Select a site at a suitable distance from the construction pier for leveling and hardening to provide good working conditions for subsequent construction;

[0017] (2) Installation frame fabrication: The installation frame is mainly composed of steel sections. The size of the frame is adjusted according to the on-site construction requirements. After the steel section frame is formed, the stepping plates and guardrails are installed in sequence. The frame is connected by bolts or welded, and the construction is carried out layer by layer to finally form an installation frame containing three working platforms.

[0018] (3) Reinforcing bar installation and positioning: Workers position and install reinforcing bars on the frame;

[0019] (4) Overall lifting: Use a tower crane to lift the pier column reinforcement as a whole until it is installed at the reinforcement installation position;

[0020] (5) It solved the problem of difficult control of the concrete cover of steel bars.

[0021] This patent has the following advantages and beneficial effects:

[0022] (1) The installation frame is located on the ground, and all work is completed on the ground, reducing construction safety risks;

[0023] (2) Fix the reinforcing bars by using the hangers on the mounting frame to prevent the reinforcing bars from leaning against the mounting frame.

[0024] An innovative method of integral lifting and installation: The main reinforcing bars are first positioned and connected on the ground using square piers, then lifted and installed as a whole by a tower crane. This method significantly increases the speed of reinforcing bar installation and effectively prevents the bars from tipping over during construction. Compared to traditional installation methods, which involve installing bars or sections one by one, it reduces the working time of personnel at height, lowers safety hazards, and alleviates the labor intensity of construction workers.

[0025] Improved positioning accuracy: The main reinforcing bars of the pier column are positioned and installed using a positioning frame. The setup in this application enables a qualitative leap in the installation accuracy of the pier column reinforcing bars, ensuring the accuracy of the reinforcing bar installation position and laying a solid foundation for subsequent construction procedures.

[0026] Improved construction efficiency and standardized operations: Reinforcing bars are installed using scaffolding and rebar assembly frames, followed by overall hoisting and installation. The main reinforcing bars on the four sides of the pier can be fabricated and installed separately, allowing for parallel or continuous construction. This significantly reduces rebar installation time to one-quarter of the original time. Furthermore, this construction method facilitates standardized, regulated, and factory-like operations, helping to save time and labor costs, and improving the overall project efficiency.
