Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a positioning device for pre-embedded reinforcement bars in a pier cap. Background Technology

[0002] A pier cap is a reinforced concrete platform located on top of a bridge pile foundation. It is an important structure connecting the bridge columns and the pile foundation, and can evenly distribute and transfer the bridge load to the lower pile foundation, thereby enabling the bridge to form a stable and reliable overall stress system.

[0003] In recent years, bridge construction has seen continuous innovation in the connection methods between columns and abutments, resulting in various approaches such as socket connections, rebar anchoring connections, and grouting sleeve connections. Among these, grouting sleeve connections are widely used due to their excellent anchoring performance and high construction efficiency. However, this connection method requires high precision in the positioning of the rebar during construction, necessitating the assistance of high-precision positioning equipment. Ordinary positioning devices, with their simple structures, often cannot reliably position the rebar, which can easily lead to insufficient assembly precision between the columns and abutments, affecting the safety of the bridge.

[0004] Therefore, it is urgent to design a pre-embedded rebar positioning device to solve the above-mentioned problems in the existing technology. Utility Model Content

[0015] Preferably, the foundation pre-embedded reinforcement positioning device further includes a connecting rod, and the positioning module has a connecting hole, with the connecting rod sequentially passing through the connecting holes on multiple positioning modules.

[0016] Preferably, multiple positioning modules are provided, and the multiple positioning modules are connected in sequence to form a rectangular structure with the ends connected.

[0017] The positioning module includes a side positioning module and a corner positioning module. The side positioning modules are located on the four sides of the rectangular structure, and the corner positioning modules are located at the corners of the rectangular structure.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0040] like Figure 1 and Figure 2As shown, this utility model provides a positioning device for embedded reinforcement bars in a foundation, used to position the vertical embedded reinforcement bars 100 of the foundation. The positioning device includes a positioning module, a fastener 3, and a fixing rod 4. The positioning module is used to fit onto the embedded reinforcement bar 100, and the positioning module is close to the side of the embedded reinforcement bar 100 along a first direction. The fastener 3 is disposed on the positioning module, and the positioning module is fixedly connected to the embedded reinforcement bar 100 by the fastener 3. The spacing between two adjacent positioning modules is adjustable along the arrangement direction of the embedded reinforcement bar 100. The first direction is the length direction of the embedded reinforcement bar 100. One end of the fixing rod 4 is fixedly connected to the enclosure template 200 of the foundation, and the other end of the fixing rod 4 is fixedly connected to the positioning module. Specifically, since the positioning module is attached to the side of the embedded reinforcement 100 along the first direction and is fixedly connected to the embedded reinforcement 100 by fasteners 3, the positioning module and fasteners 3 work together to fix and limit the embedded reinforcement 100, preventing it from bending under external force. Since the two ends of the fixing rod 4 are fixedly connected to the enclosure template 200 and the positioning module respectively, the position of the positioning module can be fixed by the fixing rod 4, thereby effectively positioning the embedded reinforcement 100 inside and preventing it from shifting under external force. This foundation embedded reinforcement positioning device has a simple structure, is easy to use, can reliably position and fix the embedded reinforcement 100 of the foundation, is detachable and reusable, and effectively improves construction efficiency and quality.

[0041] In this embodiment, when using the foundation pre-embedded reinforcement positioning device, the positioning module is placed on the steel reinforcement frame of the lower foundation, so that the pre-embedded reinforcement 100 passes through the positioning module. After the pre-embedded reinforcement 100 and the positioning module are fixed by the fastener 3 and the fixing rod 4, the construction personnel pour the lower foundation. During this process, the position of the pre-embedded reinforcement 100 remains fixed. After the foundation has solidified and formed, the foundation pre-embedded reinforcement positioning device is removed and taken off the foundation. Then, the prefabricated column is assembled on the foundation.

[0042] The specific structure of the positioning module can be set according to the actual situation, as long as it can be fitted onto the embedded rib 100 along the length direction of the embedded rib 100. In this embodiment, as shown... Figure 2 and Figure 3 As shown, the positioning module includes an outer plate 11 and a perforated plate 12, with the perforated plate 12 fixedly mounted on the outer plate 11. The perforated plate 12 and the outer plate 11 together form a positioning hole, which is used for the pre-embedded reinforcing bar 100 to pass through. It should be noted that each positioning module may have only one positioning hole, or it may have two or three positioning holes. The number of perforated plates 12 welded on the outer plate 11 is not limited here.

[0043] Furthermore, such as Figure 2 and Figure 3As shown, the cross-section of the positioning hole is triangular, and the triangular positioning hole can enhance the overall stability and strength of the positioning module; in this embodiment, the outer plate 11 is a closed frame structure formed by steel plates, and the perforated plate 12 is welded to the inner wall surface of the outer plate 11.

[0044] In this embodiment, as Figure 2 and Figure 3 As shown, the positioning module has threaded holes, and the fastener 3 is screwed onto the positioning module through the threaded holes. The end of the fastener 3 extending out of the threaded holes abuts against the embedded rib 100 in the positioning holes. Specifically, the fastener 3 is a bolt, and the threaded holes are opened on the outer plate 11. After the positioning module is fitted onto the embedded rib 100 through the positioning holes, the construction personnel connect the fastener 3 to the outer plate 11 through the threaded holes and tighten the fastener 3 so that its end abuts against the embedded rib 100, thereby pressing and fixing the embedded rib 100 onto the hole plate 12.

[0045] To ensure the reliability of the connection between two adjacent positioning modules, such as Figure 2 As shown, the foundation pre-embedded reinforcement positioning device also includes connecting rods 5. Connecting holes 14 are provided on the positioning modules, and the connecting rods 5 are sequentially inserted through the connecting holes 14 on multiple positioning modules. In this embodiment, connecting holes 14 are provided on the outer plate 11 of the positioning modules along the arrangement direction. After multiple positioning modules are respectively fitted onto the pre-embedded reinforcement 100 of the foundation, the construction personnel sequentially insert the connecting rods 5 through the connecting holes of the multiple positioning modules, thereby connecting the multiple positioning modules along the arrangement direction to prevent some positioning modules from shifting during subsequent construction and affecting the positioning effect of the pre-embedded reinforcement 100. Furthermore, two connecting rods 5 are provided, and the two connecting rods 5 are inserted in parallel, thereby improving the positioning effect of the positioning modules.

[0046] The steel reinforcement frame of the foundation has multiple embedded bars 100 arranged in a rectangular pattern. Specifically, the positioning module includes a side positioning module 1 and a corner positioning module 2. The side positioning module 1 is located on the four sides of the rectangular structure, and the corner positioning module 2 is located at the corners of the rectangular structure. Further, at least eight embedded bars 100 and at least eight positioning modules are provided, and the at least eight positioning modules are connected sequentially to form a rectangular structure with ends connected. In this embodiment, twelve embedded bars 100 and eight positioning modules are provided. The positioning modules can be divided into corner positioning modules 2 and side positioning modules 1 according to their placement. Each corner positioning module 2 has one positioning hole, and each side positioning module 1 has two positioning holes. Therefore, the corner positioning module 2 is used to fit onto a single embedded bar 100 at the corner of the rectangular arrangement, and the side positioning module is used to fit onto two embedded bars 100 on the sides of the rectangular arrangement. Specifically, the outer plates 11 of the edge positioning module 1 form a closed rectangular structure, and the outer plates 11 of the corner positioning module 2 form a closed straight-line triangle or arc-shaped triangle structure. It can be understood that the specific number and layout of the edge positioning module 1 and the corner positioning module 2 can be flexibly adjusted according to the pattern of the embedded reinforcement 100 of the foundation.

[0047] like Figure 3 As shown, a positioning insert plate 13 is provided on the side positioning module 1 connected to the corner positioning module 2, and a positioning slot 21 is provided on the corner positioning module 2. The positioning insert plate 13 is inserted into the positioning slot 21, thereby improving the connection stability between the corner positioning module 2 and the side positioning module 1. In this embodiment, the positioning insert plate 13 is welded to the outer plate 11 of the side positioning module 1, and the positioning slot 21 matches the positioning insert plate 13, thereby achieving accurate positioning and stable connection between the corner positioning module 2 and the side positioning module 1.

[0048] like Figure 2 and Figure 3 As shown, the foundation pre-embedded reinforcement positioning device also includes a connector 6, which is threadedly connected to the corner positioning module 2 and the side positioning module 1 in sequence. Specifically, after all the positioning modules are installed in place, the construction personnel use the connector 6 to connect the side positioning module 1, which is adjacent to the corner positioning module 2, to the corner positioning module 2. In this embodiment, both the outer plate 11 of the corner positioning module 2 and the outer plate 11 of the side positioning module 1 are provided with threaded holes. The connector 6 is a long bolt, which is threadedly connected to the side positioning module 1, and the rod of the connector 6 extending out of the side positioning module 1 is threadedly connected to the corner positioning module 2. Therefore, the connector 6 can achieve a stable connection between the side positioning module 1 and the corner positioning module 2. At the same time, the construction personnel can also adjust the distance between the side positioning module 1 and the corner positioning module 2 through the connector 6, so that the foundation pre-embedded reinforcement positioning device can be applied to foundation pre-embedded reinforcement 100 with different spacings.

[0049] The specific structure of the fixing link 4 can be set according to the actual situation, as long as it can fix the positioning module and the enclosure template 200. In this embodiment, the fixing link 4 is a turnbuckle, also known as a turnbuckle screw, which is a commonly used metal connector in the field. Its length can be flexibly adjusted by rotating the pull rods at both ends. In order to facilitate the connection with the fixing link 4, a vertical plate 15 is welded on the outer plate 11 of the positioning module. The vertical plate 15 has a connection hole. The fixing link 4 can be fixedly connected to the vertical plate 15 by hook connection, bolt connection or other common methods, as long as it can be easily disassembled. The connection method is not limited here.

[0050] In this embodiment, the fixed link 4 is only connected to a portion of the side positioning module 1.

[0051] The specific usage method of this foundation pre-embedded reinforcement positioning device is roughly as follows (taking the rectangular pre-embedded reinforcement 100 as an example):

[0052] First, select corner positioning module 2 and side positioning module 1 according to the number of embedded ribs 100 on the bearing platform, and put corner positioning module 2 on the embedded ribs 100 at the corner of the rectangular arrangement structure along the first direction. Then, insert the connecting rod 5 into the connecting hole 14 of the side positioning module 1 on the same side of the rectangular arrangement structure in sequence, so that the side positioning modules 1 installed on the same side form a whole.

[0053] Next, the edge positioning module 1 is fitted onto the embedded rib 100 along the first direction. During the fitting of the edge positioning module 1, the positioning plate 13 of the edge positioning module 1 needs to be inserted into the positioning slot 21 of the corner positioning module 2. Then, the distance between the corner positioning module 2 and the edge positioning module 1 is adjusted by the connector 6, and the corner positioning module 2 and the edge positioning module 1 are connected by the connector 6. After the corner positioning module 2 and the edge positioning module 1 are connected, the construction personnel install fasteners 3 on the outer plate 11 and tighten the fasteners 3 so that the embedded rib 100 in the positioning hole is pressed and fixed on the hole plate 12, thereby fixing all the embedded ribs 100 to the positioning module.

[0054] Afterwards, the construction workers fixed one end of the fixing rod 4 to the outer fence template 200, adjusted the length of the fixing rod 4, and fixed the other end to the upright plate 15 of the side positioning module 1.

[0055] After the pre-embedded reinforcement positioning device for the foundation is installed, the construction workers pour concrete into the reinforcement cage of the foundation below. After the concrete has solidified, the construction workers remove the pre-embedded reinforcement positioning device from the foundation and assemble the prefabricated column onto the foundation.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
