Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a positioning jig for pier cap reinforcement. Background Technology

[0002] In the reinforcement construction of bridge pier caps, traditional reinforcement positioning methods typically lack specialized positioning devices. Construction workers rely mainly on experience and simple tools for reinforcement placement and binding, which presents several problems. Firstly, it's difficult to precisely control the position and spacing of the reinforcement, easily leading to inaccurate binding and affecting the structural strength and stability of the pier cap. Secondly, construction efficiency is low; due to the lack of effective positioning methods, workers need to spend a significant amount of time adjusting the reinforcement positions, and the reinforcement is prone to displacement during binding, making it difficult to guarantee the quality of the final product. Furthermore, some existing reinforcement positioning devices have numerous inconveniences. For example, after binding, the positioning components and lifting tools are too tightly connected to the reinforcement, making it difficult to remove the device smoothly. This not only affects subsequent construction steps but may also damage the already bound reinforcement structure, impacting the overall construction quality and progress of the pier cap.

[0017] Example 1

[0018] This embodiment provides a positioning jig for the reinforcing bars of the pier cap, such as Figure 1-2As shown, this utility model includes a supporting base frame, limiting ribs, and a positioning component 7. The supporting base frame includes a connecting crossbar 1, a supporting base rod 2, and uprights 3. There are ten uprights 3, eight of which are divided into two groups. The two groups of uprights 3 are symmetrically arranged on both sides, and the remaining two uprights 3 are located at both ends of the supporting base frame. The bottom end of the uprights 3 is located at one end of the supporting base rod 2. The uprights 3 in a group are fixed and reinforced by the connecting crossbar 1. The limiting ribs are located on the inner side of the supporting base frame. The positioning component 7 is located above the limiting ribs.

[0019] In this embodiment, firstly, according to the size and design requirements of the pier cap, the necessary materials are prepared, including connecting crossbars 1, supporting base bars 2, and uprights 3, all of which can be made of channel steel, angle steel, or square steel. Eight of the ten uprights 3 are divided into two groups and symmetrically fixed to both ends of the supporting base bar 2 using welding or bolting. Each group of four uprights 3 is located on both sides of the supporting base frame, forming a stable two-sided support structure. The other two uprights 3 are installed at both ends of the supporting base frame using mounting rods, ensuring that the bottom end of the uprights 3 is firmly connected to the supporting base bar 2. Connecting crossbars 1 are used to connect and reinforce the uprights 3, ensuring that the connection between the connecting crossbars 1 and the uprights 3 is firm and reliable, which can be achieved by welding or bolting. Next, the limiting reinforcement is installed on the inner side of the supporting base frame to ensure accurate positioning and provide basic support for the subsequent positioning of the reinforcing bars. Finally, the positioning component 7 is placed above the limiting reinforcement, ensuring that the position of the positioning component 7 meets the requirements for subsequent reinforcing bar binding.

[0020] Example 2

[0021] Based on Example 1, such as Figure 1-2 As shown, the limiting rib in this embodiment includes a lower limiting ring 5 and an upper limiting ring 6. The lower limiting ring 5 is located at the waist of the supporting base frame, and a supporting frame 4 is provided on the side of the upright 3. The lower limiting ring 5 is fixed on the supporting frame 4.

[0022] In this embodiment, a support frame 4 is made according to the structure and size of the lower limit ring 5. The support frame 4 mainly supports the weight of the lower limit ring 5 to ensure that it can be firmly installed on the side of the upright 3. It can be fixed by welding.

[0023] Example 3

[0024] Based on Example 1, such as Figure 1-2 As shown, the upper limit ring 6 in this embodiment includes a positioning horizontal plate 61 and a positioning arc plate 62. The positioning arc plate 62 is arc-shaped. The positioning horizontal plate 61 and the positioning arc plate 62 are connected end to end to form a rounded rectangle. Support blocks 64 are fixedly installed at the bottom of both the positioning horizontal plate 61 and the positioning arc plate 62. One end of the support block 64 is fixed to the side of the upright 3.

[0025] In this embodiment, for the upper limit ring 6, a positioning horizontal plate 61 and a positioning arc plate 62 are first fabricated. The positioning arc plate 62 is machined into a suitable arc shape. Then, the positioning horizontal plate 61 and the positioning arc plate 62 are connected end to end to form a rounded rectangular structure. A support block 64 is installed at the bottom of the positioning horizontal plate 61 and the positioning arc plate 62. One end of the support block 64 is connected to the side of the upright 3, which can be done by welding. When welding the support block 64, its firmness must be ensured to prevent the upper limit ring 6 from loosening during use. When installing the upper limit ring 6, its position must be accurate so that the arc portion of the positioning arc plate 62 can accurately limit the reinforcing bar, while the positioning horizontal plate 61 can constrain the reinforcing bar from the horizontal direction, thereby achieving all-round limiting of the reinforcing bar and improving the accuracy of reinforcing bar positioning.

[0026] Example 4

[0027] Based on Example 1, such as Figure 1-2 As shown, the positioning plate 61 in this embodiment has a positioning hole 63, and the positioning component 7 includes a positioning frame 71. The bottom of both ends of the positioning frame 71 is provided with positioning posts 73 that match the positioning hole 63.

[0028] In this embodiment, based on the dimensions of the positioning plate 61 of the upper limit ring 6, the position and size of the positioning hole 63 are determined according to the positioning post 73 of the subsequent positioning frame 71 to ensure precise matching between the two. For the positioning frame 71 in the positioning assembly 7, according to the size and spacing of the positioning hole 63, matching positioning posts 73 are installed at the bottom of both ends of the positioning frame 71 to ensure the fitting accuracy between the positioning post 73 and the positioning hole 63. When installing the positioning frame 71, the positioning post 73 is inserted into the positioning hole 63, so that the positioning frame 71 is placed stably on the positioning plate 61. Through the cooperation of the positioning post 73 and the positioning hole 63, the position of the positioning frame 71 is ensured to be accurate, providing a precise positioning reference for subsequent rebar tying.

[0029] Example 5

[0030] Based on Example 1, such as Figure 1-2 As shown, the positioning frame 71 in this embodiment has bottom grooves 72 at both ends.

[0031] In this embodiment, by opening bottom grooves at both ends of the positioning frame 71 made of channel steel, the positioning frame 71 can be locked between the positioning cross plates 61, thereby improving the stability of the positioning frame 71.

[0032] Example 6

[0033] Based on Example 1, such as Figure 1-2 As shown, one end of the positioning frame 71 in this embodiment has a circular hole 74, and a pull ring 75 is sleeved in the circular hole 74.

[0034] In this embodiment, a circular hole 74 is made at one end of the positioning frame 71 according to the design dimensions. Then, a suitable pull ring 75 is selected and fitted into the circular hole 74. After the rebar binding work is completed, the rebar is lifted by a crane. Construction workers can apply a pulling force to the positioning frame 71 through the pull ring 75 and conveniently pull the positioning frame 71 out of the rebar using the operating point provided by the pull ring 75. When fitting the pull ring 75, it is necessary to ensure that the connection between the pull ring 75 and the circular hole 74 is firm and flexible so that it can be easily operated when needed, and that the presence of the pull ring 75 does not affect the other functions of the positioning frame 71 or the use of the entire positioning jig.
