Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically a portable tool for positioning rebar cages for underground continuous walls. Background Technology

[0002] In modern foundation pit support and underground engineering, diaphragm walls, as a key underground support and load-bearing structure, are widely used in the foundation construction of large highways, municipal facilities, and public buildings. Their construction quality directly affects the safety and durability of the entire project, and the precision of the fabrication and installation of the reinforcing cage, as the core component of the diaphragm wall, is a crucial factor determining the final project quality.

[0003] With the continuous expansion of engineering construction scale and increasingly stringent design requirements, the reinforcement cages for diaphragm walls are showing a trend towards larger size, more complex reinforcement layout, and stricter dimensional accuracy requirements. However, in actual construction, the fabrication of the reinforcement cage is usually carried out simultaneously with the trenching of the diaphragm sections. This parallel operation method places extremely high demands on construction efficiency and precision control. If quality problems such as dimensional deviations, incorrect spacing, or overall deformation occur during the fabrication of the reinforcement cage, rework and correction are often required. If the waiting time after trenching is completed is too long, the wall-protecting effect of the slurry on the trench wall will be significantly reduced, which can easily lead to borehole collapse accidents, seriously affecting construction safety and progress, and also significantly increasing project costs.

[0004] Currently, quality control of reinforcing cages on construction sites largely relies on traditional tape measure measurements and manual visual inspection, lacking a dedicated positioning and inspection tool that is efficient, intuitive, and easy to operate. This method is inefficient, highly susceptible to human factors, and struggles to guarantee measurement consistency and accuracy, failing to meet the construction needs for rapid and high-precision fabrication of large and complex reinforcing cages.

[0005] Based on this, this utility model proposes a portable positioning tool for underground continuous wall steel cages. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a portable rebar cage positioning tool for underground continuous walls. It is simple to operate and easy to carry, allowing welders to quickly assess the current quality of the rebar cage fabrication with just their naked eyes, thus improving both efficiency and quality.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a portable underground continuous wall reinforcement cage positioning tool, including a base, four mounting sleeves are fixedly connected to the four bases respectively, four fixing sleeves are threadedly connected to the four mounting sleeves respectively, four sliding rods are slidably connected inside the four fixing sleeves respectively, four hanging rings are fixedly connected to the four sliding rods respectively, and a dimension line is provided on the four hanging rings.

[0008] Preferably, each of the four fixing sleeves is threaded with a fastening nut.

[0009] Preferably, each of the four sliding rods has four scale lines.

[0010] Preferably, the base has an "L" shaped cross-section, and the hanging loop has an "H" shaped cross-section.

[0011] Compared with existing technologies, the significant advantages of this invention are:

[0012] Firstly, this utility model achieves portability and rapid deployment of the tool through a modular and detachable structure consisting of a base, an adjustable sliding rod with scale lines, and a scale line. Construction personnel can quickly and intuitively judge the deviation between the steel bar spacing, cage shape, and design position by simply observing the scale line and the scale on the rod with their naked eyes, which greatly improves the detection efficiency and real-time performance and effectively overcomes the problems of low efficiency and easy error in traditional manual measurement with a ruler.

[0013] Secondly, in this utility model, the threaded engagement structure of the fixing sleeve and the fastening nut enables flexible adjustment and reliable locking of the height and posture of the sliding rod, ensuring that the dimensional line can remain horizontally taut for a long time. This provides a stable and accurate benchmark for the fabrication of the rebar cage, which not only strengthens the quality control of the construction process but also significantly reduces the risk of trench wall collapse caused by rework or waiting.

[0021] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0022] This utility model provides an improved portable tool for positioning rebar cages in underground continuous wall systems. The technical solution of this utility model is as follows:

[0023] like Figures 1-4 As shown, a portable underground continuous wall reinforcement cage positioning tool includes a base 1, which is an L-shaped angle steel. Four mounting sleeves 2 are fixedly connected to the four bases 1, each with an internal thread. Four fixing sleeves 3 are threadedly connected to the four mounting sleeves 2, each with a U-shaped cross-section. A screw is welded to the bottom of each fixing sleeve 3, and the screw is threadedly connected to the mounting sleeve 2. Four sliding rods 4 are slidably connected to the four fixing sleeves 3, and four hanging rings 7 are fixedly connected to each of the four sliding rods 4. Each hanging ring 7 has a dimension line 8, which is colored. The flexible cable in the color section has two colors, which are distributed alternately. Each color segment is five centimeters long, and each color segment is further subdivided into five smaller segments, each one centimeter long. Through the modular and detachable structure consisting of the base 1, sliding rod 4, and scale line 8, the tool is lightweight and can be deployed quickly. Construction personnel can quickly and intuitively judge the deviation between the steel bar spacing, cage shape, and design position by simply observing the scale line 8 and the scale on the rod. This greatly improves the detection efficiency and real-time performance, and effectively overcomes the problems of low efficiency and easy error in traditional manual measurement with a ruler.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, four fastening nuts 5 are threaded onto the four fixed sleeves 3 respectively. The height of the sliding rod 4 can be adjusted by rotating the fastening nuts 5.

[0025] Furthermore, such as Figure 2 As shown, four scale lines 6 are respectively provided on the four sliding rods 4, and the height of the sliding rods 4 can be precisely adjusted by using the scale lines 6.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, the cross-section of the base 1 is "L" shaped, the cross-section of the hanging ring 7 is "H" shaped, and the 0 mark of the scale line 6 on the sliding rod 4 is located below the hanging ring 7.

[0027] The specific working method is as follows: After the underground continuous wall reinforcement cage fabrication platform is ready, the construction personnel first place the base 1 of the four positioning units firmly at the four corners of the platform. Then, by loosening the fastening nuts 5, they adjust the expansion joints of each sliding rod 4 to the design height and use the scale lines 6 on the rods for preliminary coarse positioning. Next, the dimension lines 8 are hung on the four hanging rings 7 in sequence. By fine-tuning the expansion and contraction of each sliding rod 4 and the tightness of the fastening nuts 5, they ensure that the dimension lines 8 are in a horizontal and taut state and aligned with the theoretical outer edge of the reinforcement cage. Finally, during the reinforcement cage binding and welding process, the construction personnel can directly observe the color sections of the dimension lines 8 and the scales on the sliding rods 4 to quickly and intuitively monitor the deviations in the reinforcement spacing, cage dimensions, and overall planar position, thereby achieving efficient and accurate quality control.

[0028] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
