[0002] In the field of bridge construction, the positioning of the steel bars of a wall - type guardrail is a crucial link, which not only concerns the stability of the wall, but also affects the stability of the entire bridge structure. The traditional method of steel bar positioning mainly relies on manual measurement and positioning, and simple tools such as a tape measure, a spirit level, and a plumb bob are used to determine the position of the steel bars. Although this method has been widely used in past construction, with the improvement of construction standards, its limitations have become increasingly prominent.

[0003] 1. In terms of economy: The traditional method requires a large amount of manual input. It is necessary to repeatedly measure and adjust the position of the steel bars to ensure quality and safety, which not only increases the labor cost but also increases the time cost. Especially in large - scale bridge construction, the steel bar positioning needs to be carried out many times, seriously affecting the economic benefits.

[0004] 2. In terms of accuracy: The positioning accuracy of manual measurement is relatively low. Therefore, it is necessary to repeatedly measure and adjust, but even a small deviation in accuracy may have a significant impact on the stability of the wall and the overall structural stability, and may even cause certain safety and quality hazards.

[0005] 3. In terms of efficiency: The traditional method of steel bar positioning is complex in operation and requires construction workers to have rich experience and skills. At the same time, due to the cumbersome measurement and adjustment process, the construction efficiency is seriously affected.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings.

[0028] As Figure 1 and Figure 2 shown, this embodiment provides an adjustable wall - type guardrail steel bar positioning device, which includes a base 1, an adjusting mechanism 2, a support frame 3, a positioning component 4 and a spirit level 5. The support frame 3 is in the shape of a vertical rod, and the base 1 is in the shape of a horizontal rod. The bottom of the support frame 3 is rotatably connected to one end of the base 1. One end of the adjusting mechanism 2 is connected to the middle of the support frame 3, and the connection position is on the side of the support frame 3 facing the base 1. The other end is fixedly connected to the upper surface of the base 1 away from the support frame 3. The positioning component 4 is installed on the side of the support frame 3 facing away from the base 1, and its specifications are pre - fabricated according to the size of the bridge guardrail and the specifications of the steel bar 8 used. The spirit level 5 is installed on the side of the support frame 3 where the positioning component 4 is installed. Among them, the base 1 serves as the support foundation of the device, and its horizontal - rod - shaped design provides sufficient support area to ensure the stability of the device on the beam body 6. The support frame 3 is used to support the positioning component 4. The bottom of the support frame 3 is rotatably connected to the base 1, allowing the angle to be adjusted within a certain range. When there is a deviation in the position and size between the positioning component 4 and the positioning steel bar 7, the relative position between the support frame 3 and the base 1 is adjusted, and then the position of the positioning component 4 is adjusted to improve the positioning accuracy of the steel bar 8. The above - mentioned adjustment is achieved through the adjusting mechanism 2. The positioning component 4 is used to position and fix the steel bar 8, and the spirit level 5 is used to observe whether the device is level.

[0029] It should be noted that during the installation process of the wall - type guardrail, the beam body 6 often serves as the support foundation of the guardrail and also determines the installation position and overall layout of the guardrail; the positioning steel bar 7 is usually used in bridge construction to provide accurate positioning and reference points to ensure that other steel bars (steel bar 8 in this example) can be accurately installed at the predetermined positions according to the design requirements. Usually, the positioning steel bar 7 is first fixed on the beam body 6 as the benchmark for subsequent installation; the steel bar 8, as part of the guardrail steel bar framework, is used to support the guardrail and improve the load - bearing capacity and anti - deformation ability of the guardrail.

[0030] Specifically, as Figure 1 and Figure 2 shown, the adjusting mechanism 2 includes a hook 22, a ring 23, a rotating member 21 and a fixing member 24. One end of the hook of the hook 22 is hung on the middle part of the support frame 3. A thread is provided at the tail of the hook 22, which is threadedly connected to one end of the rotating member 21. Similarly, a thread is provided at the head of the ring 23, which is threadedly connected to the other end of the rotating member 21. The tail of the ring 23 is annular and is connected to one end of the fixing member 24. The fixing member 24 is fixedly connected to the upper surface of the base 1 at the end far from the support frame 3.

[0031] Specifically, as Figure 1 and Figure 2 shown, the positioning assembly 4 includes a first positioning member 41 and a second positioning member 42. The first positioning member 41 and the second positioning member 42 are provided with clamps or chucks. The first positioning member 41 is composed of two upper and lower parts, where the lower part is shorter than the upper part. The second positioning member 42 is shorter than the first positioning member 41. One end of the first positioning member 41 is installed on one side of the top of the support frame 3, and one end of the second positioning member 42 is installed on the same side of the support frame 3, and the second positioning member 42 is located below the first positioning member 41. The designs of the first positioning member 41 and the second positioning member 42 take into account the size and position requirements of the steel bar 8 and can firmly hold the steel bar 8 to prevent it from shaking or being misaligned.

[0032] The working principle of this embodiment is as follows:

[0033] Preparation work: Prepare the necessary installation tools to ensure that all structural parts are complete, without damage and deformation. Customize the positioning assembly 4 that conforms to the size of the bridge guardrail and the used steel bar 8, and install it on the support frame 3. Vertically install the support frame 3 on the base 1 and connect the adjusting mechanism 2.

[0034] Adjustment work: Place the device on the beam body 6, align the connecting end of the base 1 and the support frame 3 with the positioning reference line on the beam body 6. Use the spirit level 5 to observe whether the device is level. If necessary, level it by adjusting the adjusting feet (not marked in the figure) at the bottom of the support frame 3, and then fix the device on the beam body 6 with screws to ensure its stability without shaking.

[0035] As Figure 2As shown, observe the positions of the positioning component 4 and the positioning steel bars 7 on the beam body 6. According to the diameter and position requirements of the steel bars 8, by rotating the hook 22, a displacement occurs between the hook 22 and the rotating member 21, so that the support frame 3 drives the positioning component 4 to move, ensuring that the positioning component 4 accurately corresponds to the positioning steel bars 7.

[0036] For the positioning work, as Figure 1 shown, place the steel bar 8 to be fixed on the beam body 6, align the adjusted device with the steel bar 8, align the end of the base 1 connected to the support frame 3 with the positioning reference line on the beam body 6, and firmly clamp the steel bar 8 through the fixture or card slot on the positioning component 4 to ensure that the steel bar 8 is in close contact with the positioner, that is, the first positioning member 41 abuts against the top of the steel bar 8, and the outer end of the second positioning member 42 abuts against the steel bar 8, without any shaking or dislocation.

[0037] Determine the positioning situation of the steel bar 8. If necessary, the position of the positioner can be adjusted again to ensure that the positioning accuracy of the steel bar 8 meets the requirements. After the positioning is completed, fix the steel bar 8 on the beam body 6, and the steel bar 8 can be reinforced by welding or using additional fasteners to improve its stability and firmness.

[0038] At the same time, check whether the support frame 3 and the fasteners are firm and reliable, without any looseness or detachment. After ensuring that there is no error, carry out the positioning of the next steel bar 8.

[0039] The above has described a specific embodiment of the present invention in detail, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
