Description

Technical Field

[0001] This application relates to the field of building steel reinforcement technology, and in particular to a spacing fixing structure for preventing steel reinforcement from shifting. Background Technology

[0002] Steel reinforcement bars are the core load-bearing components in reinforced concrete structures. They are made of carbon steel or alloy steel through smelting and rolling, and their cross-sections are mostly circular or square with rounded corners. They are divided into plain round bars, ribbed bars, and other types. Their core function is to bear tensile stress, compensating for the low tensile strength of concrete, while enhancing the overall integrity and crack resistance of the structure. They are widely used in the foundations, beams, columns, and floor slabs of buildings, bridges, and other structures, effectively resisting external loads such as earthquakes and gravity, and ensuring the safety and stability of the structure.

[0003] Currently, rebar supports are mostly connected using stirrups. However, during the binding phase, frequent stepping by workers can easily cause the placed rebars to tilt, leading to a shift in the spacing of the upper rebars. Furthermore, during the concrete pouring process, the impact of the vibrator and the lateral pressure from the falling concrete can cause the supporting rebar cage to shift, resulting in excessive deviations in the thickness of the concrete cover, affecting the structural performance and posing safety hazards. Therefore, to solve these problems, we provide a spacing fixing structure to prevent rebar displacement. Utility Model Content

[0004] The purpose of this utility model is to provide a spacing fixing structure to prevent rebar misalignment, so as to solve the problems mentioned in the background art.

[0005] The embodiments of this application adopt the following technical solutions: A spacing fixing structure for preventing rebar misalignment includes vertical rebars, with multiple upper horizontal rebars fixedly connected to the outer surface of the vertical rebars, each upper horizontal rebar having a first U-shaped positioning element on its outer surface, and multiple lower horizontal rebars fixedly connected to the outer surface of the vertical rebars, each lower horizontal rebar having a second U-shaped positioning element on its outer surface.

[0006] Preferably, the first U-shaped positioning component includes an upper arc-shaped clamping plate, the bottom surface of which is hinged to a lower arc-shaped clamping plate via a pin, the upper horizontal reinforcing bar being located between the upper and lower arc-shaped clamping plates, and a U-shaped block being fixedly connected to the upper surface of the upper arc-shaped clamping plate.

[0007] Preferably, the upper surface of the U-shaped block is provided with two sets of anti-slip protrusions, and anti-slip fixing pads are fixedly connected to one side of the upper arc-shaped clamp and one side of the lower arc-shaped clamp. The sides of the two anti-slip fixing pads that are close to each other are in close contact with the outer surface of the upper horizontal reinforcing bar.

[0008] Preferably, an upper fixing plate is fixedly connected to one side of the upper arc-shaped clamping plate, a lower fixing plate is fixedly connected to one side of the lower arc-shaped clamping plate, a fixing screw is fixedly connected to the bottom surface of the upper fixing plate, and a locking nut is threaded onto the outer surface of the fixing screw.

[0009] Preferably, the bottom end of the vertical reinforcing bar is fixedly connected to a bottom reinforcing bar, and the first U-shaped positioning component and the second U-shaped positioning component are both made of the same specifications.

[0010] Preferably, the depth of the U-shaped block is greater than the diameter of the reinforcing bar to be placed.

[0011] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: This spacing fixing structure to prevent rebar misalignment uses a first U-shaped positioning piece and a second U-shaped positioning piece installed on the surfaces of the upper and lower horizontal rebars. The first and second U-shaped positioning pieces can be flexibly adjusted in position on the surfaces of the upper and lower horizontal rebars, thereby achieving the effect of spacing adjustment. Furthermore, the U-shaped blocks of the first and second U-shaped positioning pieces are embedded in the upper and lower layers of rebars respectively, which can limit the rebars. Even if people step on them during binding, the rebars will not slip. During subsequent concrete pouring, they can also resist the compression and vibration impact of concrete, preventing rebar misalignment. In addition, the cross-shaped frame formed by the upper and lower horizontal rebars and the vertical rebars retains the supporting function of traditional stirrups while enhancing overall stability and improving the safety of the building structure.

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0015] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0016] Please see Figure 1-4 This utility model provides a technical solution for fixing the spacing of reinforcing bars to prevent misalignment: A spacing fixing structure to prevent rebar displacement includes a vertical rebar 1, with multiple upper horizontal rebars 2 fixedly connected to the outer surface of the vertical rebar 1. Each upper horizontal rebar 2 has a first U-shaped positioning element 3 on its outer surface. Multiple lower horizontal rebars 4 are fixedly connected to the outer surface of the vertical rebar 1, with a second U-shaped positioning element 5 on the outer surface of each lower horizontal rebar 4. Specifically, the vertical rebar 1 provides an installation foundation for the upper and lower horizontal rebars 2 and 4. The multiple upper and lower horizontal rebars 2 and 4 are fixed to the surface of the vertical rebar 1, forming a support frame. The first U-shaped positioning element 3 and the second U-shaped positioning element 5 are respectively installed on the surfaces of the upper and lower horizontal rebars 2 and 4, respectively, to position and place the upper and lower rebars, preventing the rebars from shifting during construction and ensuring that the rebar spacing meets the design requirements.

[0017] In this embodiment, the first U-shaped positioning component 3 includes an upper arc-shaped clamping plate 31. A lower arc-shaped clamping plate 33 is hinged to the bottom surface of the upper arc-shaped clamping plate 31 via a pin. The upper horizontal reinforcing bar 2 is located between the upper arc-shaped clamping plate 31 and the lower arc-shaped clamping plate 33. A U-shaped block 32 is fixedly connected to the upper surface of the upper arc-shaped clamping plate 31. Two sets of anti-slip protrusions 37 are provided on the upper surface of the U-shaped block 32. Anti-slip fixing pads 39 are fixedly connected to one side of the upper arc-shaped clamping plate 31 and one side of the lower arc-shaped clamping plate 33. The sides of the two anti-slip fixing pads 39 that are close to each other are in close contact with the outer surface of the upper horizontal reinforcing bar 2. An upper fixing plate 35 is fixedly connected to one side of the upper arc-shaped clamping plate 31, and a lower fixing plate 34 is fixedly connected to one side of the lower arc-shaped clamping plate 33. The bottom surface of the upper fixing plate 35 is fixedly connected to a fixing screw 36, and the outer surface of the fixing screw 36 is threaded with a locking nut 38. Specifically, the upper arc-shaped clamping plate 31 and the lower arc-shaped clamping plate 33 are hinged by a pin, which can wrap and fix the upper horizontal reinforcing bar 2. The U-shaped block 32 is used to place the upper layer of reinforcing bar, and the anti-slip protrusions 37 on its surface can increase the friction with the reinforcing bar and prevent the reinforcing bar from sliding. The anti-slip fixing pad 39 is tightly attached to the upper horizontal reinforcing bar 2 to enhance the fixing effect between the clamping plate and the reinforcing bar. The upper fixing plate 35 and the lower fixing plate 34, together with the fixing screw 36 and the locking nut 38, can firmly fix the clamping plate and prevent the positioning parts from loosening. In addition, the upper fixing plate 35 and the lower fixing plate 34 can also be fixed by welding to reduce the cost of use.

[0018] In this embodiment, the bottom end of the vertical steel bar 1 is fixedly connected to the bottom bar 6. The first U-shaped positioning component 3 and the second U-shaped positioning component 5 are both made of the same specifications. The depth of the U-shaped block 32 is greater than the diameter of the steel bar to be placed. Specifically, the bottom bar 6 enhances the overall stability of the structure and prevents the vertical steel bar 1 from tilting. The first U-shaped positioning component 3 and the second U-shaped positioning component 5 are of the same specifications, which facilitates unified procurement and installation and reduces construction costs. The depth of the U-shaped block 32 is greater than the diameter of the steel bar to be placed, which can completely embed the steel bar and further restrict the movement of the steel bar, ensuring the stability of the steel bar position during the binding and pouring process.

[0019] Working principle: When this spacing fixing structure for preventing rebar deviation is used, firstly, multiple upper horizontal rebars 2 and lower horizontal rebars 4 are fixed on the surface of the vertical rebar 1. According to the spacing in the construction drawings, the first U-shaped positioning piece 3 is installed on the surface of the upper horizontal rebar 2, and the second U-shaped positioning piece 5 is installed on the surface of the lower horizontal rebar 4. The two are of the same specification and installed in the same way. When installing the first U-shaped positioning piece 3, the upper horizontal rebar 2 is placed between the upper arc-shaped clamp 31 and the lower arc-shaped clamp 33. The clamp is closed by the pin shaft, so that the anti-slip fixing pads 39 on both sides are in close contact with the upper horizontal rebar 2, and the locking nut 38 is screwed into the surface of the fixing screw 36 to complete the fixation. At the same time, the depth of the U-shaped block 32 is matched with the diameter of the rebar, which can reserve space for the rebar placement.

[0020] In use, the upper horizontal steel bar 2 and the lower horizontal steel bar 4, together with the vertical steel bar 1, form a cross-shaped support frame that is larger at the top and smaller at the bottom, supporting the upper and lower layers of steel bars. The upper layer of steel bars is placed into the U-shaped block 32 of the first U-shaped positioning piece 3, and the lower layer of steel bars is placed into the U-shaped structure of the second U-shaped positioning piece 5. The anti-slip protrusions 37 on the U-shaped block 32 increase the friction between the steel bars and the positioning piece; during the binding stage, even if people step on it, the steel bars can be prevented from sliding.
