Technical Field

[0001] The invention belongs to the technical field of bridge construction, and in particular relates to a bridge pier reinforcement positioning placenta. Background Art

[0002] With the rapid development of transportation, the role of bridges has become increasingly prominent. Traditional bridges refer to fixed structures across rivers and other water bodies, but modern bridges are much more than that, and also include various types of viaducts, cross-sea bridges, etc.

[0003] Regardless of the form of the bridge, piers are indispensable. Although there are some examples of large spans without piers in the middle, piers still need to be set at both ends of the bridge as the basis for bridge erection.

[0004] The existing bridge piers are concrete structures, which are made of concrete cast steel skeletons. During the construction of the bridge piers, the problem of non-parallel longitudinal steel bars is often encountered, resulting in poor strength uniformity of the entire bridge pier, affecting the quality of the bridge pier and failing to meet the design requirements. Summary of the invention

[0005] The purpose of the embodiment of the present invention is to provide a bridge pier column reinforcement positioning placenta, which aims to solve the problem of non-parallel longitudinal reinforcement often encountered during the construction of existing piers, resulting in poor strength uniformity of the entire pier, affecting the quality of the pier, failing to meet the design requirements, and requiring improvement.

[0006] An embodiment of the present invention is implemented as follows: a bridge pier steel bar positioning placenta includes a positioning frame and a connecting plate, wherein at least two positioning frames are provided, and a plurality of connecting sleeves are provided on the positioning frame, wherein the middle of the connecting sleeve is through-through, and the connecting sleeves penetrate the upper and lower sides of the positioning frame; the connecting plate is connected to the side of the positioning frame, and is used to connect at least two of the positioning frames into one.

[0007] The bridge pier column reinforcement positioning placenta provided by the present invention allows the reinforcement to pass through the connecting sleeve and utilizes the rigidity of the positioning frame and the connecting plate to prevent the reinforcement from being misplaced before pouring, thereby ensuring the parallelism of the reinforcement in the pier and ensuring the quality of the pier.

[0011] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0012] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0013] like Figure 1 , 2 As shown, it is a structural diagram of a bridge pier column reinforcement positioning placenta provided by an embodiment of the present invention, including a positioning frame 1 and a connecting plate 2. At least two positioning frames 1 are provided, and a plurality of connecting sleeves 3 are provided on the positioning frame 1. The middle part of the connecting sleeve 3 is passed through, and the connecting sleeve 3 penetrates the upper and lower sides of the positioning frame 1; the connecting plate 2 is connected to the side of the positioning frame 1, and is used to connect at least two of the positioning frames 1 into one.

[0014] In an embodiment of the present invention, the positioning frame 1 can be set as a circular frame or any other polygonal frame. When set as a circular frame, the connecting plate 2 should include a circular arc portion, through which it is connected to the positioning frame 1. The specific form of the positioning frame 1 is related to the distribution of the steel bars in the pier. According to the distribution of the steel bars, the shape of the positioning frame 1 can be freely set, and the present invention does not make specific limitations on this. In the present invention, a detachable connection can be adopted between the connecting plate 2 and the positioning frame 1 to facilitate the assembly of the two. When in use, the steel bars can be first inserted into the positioning frame 1 and then at least two positioning frames 1 can be connected and fixed by the connecting plate 2. This is an optional specific implementation method, and the embodiment of the present invention does not make specific limitations on this.

[0015] like Figure 2 As shown, preferably, the end of the connecting sleeve 3 located on the upper side of the positioning frame 1 is provided with a plurality of locking holes 5. In the embodiment of the present invention, a plurality of positioning holes can be provided around the circumference of the connecting sleeve 3, and the function of the positioning holes is to relatively fix the steel bar and the positioning sleeve. The fixing method can be achieved by driving a positioning pin into the positioning hole that is transitional or interference fit with the positioning hole, or by screwing in a locking screw to achieve locking.

[0016] like Figure 2As shown, preferably, a plurality of legs 6 are provided on the inner side of the positioning frame 1. Furthermore, the legs 6 include a fixing portion and an adjusting portion, and the fixing portion is connected to the adjusting portion by a thread. In the present invention, the legs 6 have two functions, one is to support the positioning frame 1, and the other is to achieve the horizontality of the positioning frame 1 by leveling, so that the steel bars remain in a vertical state. As an optional specific implementation method, a level indicator tube can also be provided on the positioning frame 1. The liquid encapsulated in the level indicator tube determines whether the positioning frame 1 is horizontal by observing the position of the bubbles in the liquid. In an embodiment of the present invention, the positioning frame 1 can be adjusted to maintain a horizontal state by rotating the adjusting portion.

[0017] Preferably, a plurality of lifting lugs 4 are provided on the connecting plate 2. In the embodiment of the present invention, the lifting lugs 4 are used for lifting the bridge pier column steel bar positioning placenta provided by the present invention. Preferably, the lifting lugs 4 are symmetrically arranged, and the symmetry center roughly coincides with the center of mass of the bridge pier column steel bar positioning placenta, so that the balance of the bridge pier column steel bar positioning placenta can be maintained during lifting.

[0018] Preferably, the positioning frame 1 is a rectangular frame formed by four channel steels connected end to end. Furthermore, the bottom edges of the channel steels on one set of opposite sides of the positioning frame 1 are close to each other, and the bottom edges of the channel steels on another set of opposite sides of the positioning frame 1 are far away from each other. Still further, the connecting plate 2 is a channel steel, and the bottom edge of the channel plate constituting the connecting plate 2 is in contact with a group of channel steels constituting the bottom edge of the positioning frame 1 that are far away from each other. In the embodiment of the present invention, it can be understood that the channel steel is a profile with a U-shaped cross section, and the channel material has good strength and light weight. It can be applied to the present invention to facilitate the setting of the connecting sleeve 3, and the installation of the connecting sleeve 3 can be achieved by only punching holes on the two sides of the channel steel.

[0019] Preferably, the connecting plate 2 includes a first connecting plate 2 and a second connecting plate 2 , and the first connecting plate 2 and the second connecting plate 2 are arranged in parallel.

[0020] The method of using the present invention is as follows: pass the steel bar through the connecting sleeve 3, move the positioning frame 1 up and down to the appropriate position, keep the positioning frame 1 horizontal by adjusting the adjustment part of the support foot 6, and then lock the positioning frame 1 and the steel bar by the positioning pin or locking screw; then connect and fix several positioning frames 1 through the connecting plate 2 to adjust the horizontal position of the positioning frame 1. It should be understood that the above description is based on the method of first inserting the steel bar and then connecting and fixing it. In practice, the bridge pier steel bar positioning placenta can also be assembled and fixed, and then hoisted as a whole, and inserted into the erected steel bar from top to bottom. As another specific use of the present invention, the assembled bridge pier steel bar positioning placenta is hoisted in the air by hoisting equipment, and the erected steel bar is passed through the connecting sleeve 3 and the hoisting state of the hoisting equipment is maintained. This method can achieve positioning from the top of the steel bar, which is suitable for short-term construction.
