Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a positioning clamp for steel bars in bridge piers. Background Technology

[0002] In bridge engineering, bridge piers are an important component, serving to support the bridge span structure. Precise positioning of the pre-embedded reinforcing bars in the pier body during the concrete pouring process is crucial to ensuring the quality of the pier reinforcement construction.

[0003] In existing technologies, the precise positioning of bridge pier reinforcement bars mainly relies on manual methods. Effective measures are generally not taken to prevent the reinforcement bars from becoming misaligned, which reduces the construction qualification rate of the reinforcement bars, increases the construction period and cost, and also shortens the lifespan of the bridge.

[0004] In the prior art, such as the utility model patent with patent number 2020220319665, a bridge pier rebar positioning clamp is disclosed, including a first rebar limiting ring placed on a base surface, a plurality of first limiting grooves spaced apart along its circumference on the first rebar limiting ring, at least one second rebar limiting ring disposed above the first rebar limiting ring, and a plurality of second limiting grooves respectively corresponding one-to-one with the plurality of first limiting grooves on the second rebar limiting ring, and the first rebar limiting ring and the second rebar limiting ring are connected by a plurality of vertically placed connecting plates, and the plurality of connecting plates are along the first rebar... The circumferentially spaced limiting rings allow one end of the reinforcing bar to pass vertically through the corresponding first and second limiting grooves and extend below the base surface. The dimension from the first limiting groove to the outside of the first reinforcing bar limiting ring and the dimension from the second limiting groove to the outside of the second reinforcing bar limiting ring are greater than the thickness of the protective layer of the structure. This structure is designed for bridge structures that require the formation of drip grooves in the pier body. However, in use, the formation of drip grooves will result in the distance between the reinforcing bar and the bottom of the drip groove being too small, leading to weak reinforcement of the reinforcing bar. Therefore, it is not suitable for positioning the reinforcing bar of such bridge piers. Based on this, it is necessary to study a bridge pier reinforcing bar positioning clamp. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a bridge pier rebar positioning clamp, which effectively solves the problem that the existing bridge pier rebar positioning clamps are not suitable for piers with drip grooves, and direct use will result in weak reinforcement of the rebar.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a bridge pier rebar positioning clamp, comprising an upper clamping plate, a lower clamping plate, a connecting frame, and a slotted positioning block; the upper and lower clamping plates are provided with corresponding positioning holes, and the two are fixedly connected together by a connector; the slotted positioning block has a U-shaped structure, and the slotted positioning block is correspondingly clamped in the middle of the upper and lower clamping plates, and extends into the interior of the upper and lower clamping plates; the slotted positioning block is provided with slotted positioning holes.

[0007] Furthermore, both the upper and lower clamping plates include arc-shaped segments and straight segments, which are connected and combined to form a clamping structure with arc-shaped ends and a straight middle section; the positioning holes are circular and evenly distributed on the arc-shaped and straight segments.

[0008] Furthermore, the arc-shaped segment and / or straight segment is composed of multiple segments spliced ​​together.

[0009] Furthermore, a fixing hole is provided in the middle of the slot positioning block, and corresponding circular holes are provided on the upper and lower clamping plates. The slot positioning block is fixed on the upper and lower clamping plates by arranging bolts in the fixing hole and the circular holes.

[0010] Furthermore, when the slot positioning block is fixed, its inner wall fits and adheres to the upper and lower clamping plates.

[0011] Furthermore, the connecting frame includes a vertical rod and a reinforcing rod. The vertical rod is vertically connected between the upper and lower clamping plates, and the reinforcing rod is inclined and alternately fixedly connected to the vertical rod at its first and second ends.

[0012] Furthermore, the reinforcing rod includes a cross reinforcing section in the middle and front and rear connecting reinforcing sections on both sides.

[0013] Furthermore, the upper and lower clamping plates are plate-shaped structures, and the slot positioning block has a slot, the depth of which is adapted to the width of the upper and lower clamping plates.

[0014] The beneficial effects of the above technical solution are as follows: This invention is applied to the precise positioning of bridge pier reinforcement bars during the concrete pouring process of the abutment. Traditional construction methods generally do not employ measures for reinforcement bar positioning control, relying entirely on the skills of the construction workers, making it difficult to guarantee construction quality. This invention is simple to manufacture, low in cost, and reusable, effectively improving the construction quality of pre-embedded pier reinforcement bars in the abutment and ensuring the accuracy of the reinforcement bar spacing and protective layer thickness.

[0015] In its specific structure, this utility model arranges an upper plate and a lower plate, which are combined and connected using a connecting frame. A slotted positioning block is provided in the middle of the upper plate and the lower plate. The slotted positioning block is assembled onto the plate by bolts, and a rebar positioning hole is provided on the slotted positioning block, which allows the rebar to extend inward and positions the rebar from the upper and lower layers, so that the rebar arrangement shape matches the outer surface of the bridge pier and ensures that the position of the rebar matches the spacing of the surface.

[0016] This invention improves the accuracy of positioning the pre-embedded reinforcing bars in the pier cap, ensuring that the spacing of the reinforcing bars and the thickness of the protective layer meet the requirements. The positioning clamps are simple to manufacture, low in cost, and reusable, effectively improving the construction quality of the pre-embedded reinforcing bars in the pier cap, reducing subsequent construction time and costs, and extending the service life of the bridge.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0024] Example 1: This example aims to provide a bridge pier rebar positioning clamp, primarily used for positioning the rebar in bridge piers. Currently, during the concrete pouring process of bridge abutments, effective measures are generally not taken to control the positioning of the pre-embedded rebar in the pier, relying entirely on the skills of the construction workers, making it difficult to guarantee the construction quality of the pre-embedded rebar. This invention provides a simple, low-cost, and reusable pier rebar positioning clamp to ensure accurate positioning of the rebar and guarantee that the rebar spacing and protective layer thickness meet requirements.

[0025] like Figure 1-5 The image shows a bridge pier rebar positioning clamp, which includes an upper clamping plate 1, a lower clamping plate 2, a connecting frame 4, and a slotted positioning block 5. The upper clamping plate 1 and the lower clamping plate 2 are provided with corresponding positioning holes 3, and the two are fixedly connected together by the connecting frame 4. In this embodiment, the upper clamping plate 1 and the lower clamping plate 2 are plate-shaped structures, and their whole structure is a continuous closed structure.

[0026] In the specific structure, both the upper clamping plate 1 and the lower clamping plate 2 include arc-shaped segments and straight segments. The arc-shaped segments and straight segments are connected and combined to form a clamping structure with arc-shaped ends and a straight middle. The positioning holes are circular and evenly distributed on the arc-shaped segments and straight segments. The arc-shaped segments and / or straight segments are spliced ​​together from multiple segments. The specific fixing connection method can be welding assembly to form a clamping plate structure similar to a slot, with an area inside that is semi-circular at both ends and rectangular in the middle.

[0027] In specific implementation, the connecting frame 4 includes a vertical rod 41 and a reinforcing rod 42. The vertical rod 41 is vertically connected between the upper clamping plate 1 and the lower clamping plate 2. The specific fixing point of the vertical rod 41 is located between the positioning blocks. The two clamping plates are arranged opposite to each other and connected by the vertical rod 41 to form an integral structure.

[0028] To further enhance the connection strength of the vertical rod 41, the reinforcing rod 42 is inclined and its first and last ends are alternately fixed to the vertical rod 41. In the specific structure, the reinforcing rod 42 includes a cross reinforcing part in the middle and first and last connecting reinforcing parts on both sides. This structure can ensure the connection strength of the connecting frame 4 and ensure the stability of the structure.

[0029] In this embodiment, the slot positioning block 5 has a U-shaped structure. The slot positioning block 5 is correspondingly snapped into the middle of the upper clamping plate 1 and the lower clamping plate 2, and extends into the interior of the upper clamping plate 1 and the lower clamping plate 2. The width of the slot positioning block 5 is adapted to the width of the drip groove, and slot positioning holes are arranged along the edge of the slot positioning block 5. In a further structure, a fixing hole is provided in the middle of the slot positioning block 5, and corresponding circular holes are provided on the upper clamping plate 1 and the lower clamping plate 2. The slot positioning block 5 is fixed to the upper clamping plate 1 and the lower clamping plate 2 by arranging bolts in the fixing hole and the circular holes.

[0030] The slot positioning block 5 has a slot structure. The depth of the slot is adapted to the width of the upper plate 1 and the lower plate 2. When the slot positioning block 5 is fixed, its inner wall is adapted to fit against the upper plate 1 and the lower plate 2. Thus, by positioning with bolts, and with the help of the side plate of the slot positioning block 5 and the plate, it fits against the plate, thereby preventing the slot positioning block 5 from swinging, and the structure is firmly fixed.

[0031] Therefore, this embodiment employs specialized steel clamps to provide precise positioning for the pier reinforcement during the concrete pouring process, ensuring the accuracy of the reinforcement spacing and protective layer thickness. During the process, it is crucial to ensure accurate positioning of the entire clamp and a stable foundation. This clamp is specifically designed for bridge piers with drip grooves, is reusable, and effectively improves the construction quality of the embedded pier reinforcement in the pier cap, reduces subsequent construction time and costs, and extends the service life of the bridge.

[0032] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. The basic concept of this utility model is to arrange an upper clamping plate 1 and a lower clamping plate 2, and combine them using a connecting frame 4. A slotted positioning block 5 is provided in the middle of the upper clamping plate 1 and the lower clamping plate 2. The slotted positioning block 5 is assembled onto the clamping plate by bolt assembly, and a rebar positioning hole is provided on the slotted positioning block 5, thereby allowing the rebar to extend inward and adapt to the outer surface of the bridge pier, ensuring that the position of the rebar matches the spacing of the surface. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
