In complex construction environments, the error of manual operation may be further amplified, leading to inaccurate positioning of reinforcement.

[0005] Poor stability: Traditional restrictors often have difficulty providing sufficient support and fixation during concrete pouring, leading to easy displacement or vibration of reinforcement. This not only affects the positioning accuracy of reinforcement, but also may have a negative impact on the overall quality of the concrete structure.

[0006] Limited adaptability: Traditional longitudinal restrictors for concrete reinforcement can only adapt to reinforcement of specific size and shape, and may need to replace different restrictors for reinforcement of different specifications and requirements. This not only increases construction costs, but also limits the application range of the restrictor.

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely in the following by combining with the drawings in the embodiments of the utility model, obviously, the described embodiments only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without making creative labor belong to the scope of protection of the utility model.

[0027] In order to make the above purpose, features and advantages of the utility model more obvious and easy to understand, the following will be further detailed to the utility model by combining with the drawings and specific embodiments.

[0028] Embodiment one

[0029] As Figure 1 Indicated, the utility model provides a kind of adjustable longitudinal restrictor of concrete reinforcing steel bar 2, to ensure that reinforcing steel bar 2 can keep accurate longitudinal position during concrete pouring process, prevent its deviation or displacement, so as to guarantee the strength and stability of concrete structure. In the embodiment, specific structure is as follows:

[0030] The end plate 1 is made of Q235 steel plate with a thickness of 12 mm to ensure sufficient strength and stability. The symmetrical design makes the entire restrictor structure balanced and capable of bearing a large pressure.

[0031] The reinforcing bar 2 is a longitudinal reinforcing bar with a diameter of 10 mm, which is the core structure of the longitudinal restrictor. Its two ends are welded through the corresponding end plate 1 to achieve firm connection.

[0032] The U-shaped structure angle steel 3 has two vertical parts at both ends which are welded to the end plate 1. This not only enhances the overall stability of the restrictor, but also provides a mounting base for the adjustable support unit 4.

[0033] The adjustable support unit 4 is composed of a sleeve 41, a support rod 42 and an adjusting bolt 43. The bottom of the sleeve 41 is fixedly connected to the outer wall of the angle steel 3, the support rod 42 is sleeved inside the sleeve 41, and the adjusting bolt 43 is arranged on one side of the sleeve 41. One end of the adjusting bolt 43 is threadedly connected to the outer wall of the support rod 42 which is sleeved inside the sleeve 41. By adjusting the thread connection between the adjusting bolt 43 and the outer wall of the support rod 42, the extension length of the support rod 42 can be accurately adjusted.

[0034] The rubber pad 5 is provided between the top of the support rod 42 and the bottom of the reinforcing bar 2. The bottom of the rubber pad 5 is fixedly connected to the top of the support rod 42, and the top of the rubber pad 5 is in contact with the outer wall of the reinforcing bar 2. The material of the rubber pad 5 is neoprene or natural rubber, which has good elasticity and wear resistance. It not only plays a buffering role, but also increases the friction between the reinforcing bar 2 and the support rod 42.

[0035] The stainless steel probe 6 is provided at both ends of the reinforcing bar 2. It is spherical with a radius of 3 mm, which is convenient for detecting and adjusting the position of the reinforcing bar 2 during concrete pouring.

[0036] Working principle: During assembly, place the two end plates 1 symmetrically, ensure that the welding points are aligned, then weld the two vertical parts of the U-shaped structure angle steel 3 to the end plates 1 to form a stable support structure, then weld the reinforcing bar 2 at both ends to the corresponding end plate 1 to ensure that the reinforcing bar 2 penetrates the end plate 1 and is firmly connected, and finally arrange several groups of adjustable support units 4 on the angle steel 3, adjust the extension length of the support rod 42 according to actual needs, so that the top of the support rod 42 and the bottom of the reinforcing bar 2 maintain a certain distance, and place the rubber pad 5.

[0037] In use, as the concrete is poured, the steel bar 2 will be subjected to pressure and vibration from the concrete, and then the adjustable support unit 4 supports the steel bar 2 longitudinally through the support rod 42 to prevent it from being offset due to the pressure and vibration of the concrete. Because the rubber pad 5 plays a buffering role between the support rod 42 and the steel bar 2, while increasing the friction, it ensures that the steel bar 2 remains stable during pouring. If further adjustment of the position of the steel bar 2 is required, the length of the support rod 42 can be changed by rotating the adjusting bolt 43, so as to accurately adjust the longitudinal position of the steel bar 2.

[0038] Therefore, the adjustable concrete steel bar longitudinal limiter has the following beneficial effects:

[0039] (1) The utility model improves the positioning accuracy and stability of the concrete steel bar longitudinal limiter: through the design of the adjustable support unit, the technician can accurately adjust the longitudinal position of the steel bar in the concrete. The threaded connection of the adjusting bolt and the outer wall of the support rod allows the height of the support rod to be finely adjusted, thereby ensuring accurate positioning of the steel bar during pouring; at the same time, the end plate is made of Q235 steel plate, which has high strength and good toughness, and can provide stable support for the steel bar; and the setting of the rubber pad not only increases the contact area between the steel bar and the support rod, improves the stability, but also reduces the vibration and displacement of the steel bar during pouring through its elastic buffering effect.

[0040] (2) The utility model enhances the adaptability and maintainability of the concrete steel bar longitudinal limiter: by introducing the adjustable support unit and the rubber pad, the longitudinal limiter can adapt to steel bars of different sizes and shapes, as well as different construction environments and requirements. This adaptability allows the limiter to be used in various engineering scenarios, improving its application value; at the same time, due to the relatively simple structure design of the longitudinal limiter, the connection mode between the components is also relatively clear, so in the actual use process, if damage or failure occurs, it can be easily repaired and replaced.

[0041] In this paper, specific examples are applied to explain the principles and implementation methods of the utility model; the above examples are only used to help understand the method and core idea of the utility model; at the same time, for those skilled in the art, according to the idea of the utility model, the specific implementation and application range will be changed. In view of the above, the content of this specification should not be understood as a limitation of the utility model.
