Description

Technical Field

[0001] This application relates to the field of continuous beam closure segment construction, and in particular to a pre-embedded steel box structure for continuous beam closure segment. Background Technology

[0002] The construction of the closure section of a continuous beam bridge is a crucial step in bridge construction, and its quality directly affects the overall performance and lifespan of the bridge.

[0003] The construction of the closure section often employs methods such as cast-in-place concrete, precast assembly, or pre-embedded steel boxes. However, the cast-in-place concrete and precast assembly methods are susceptible to environmental factors during construction, leading to less than ideal results. The pre-embedded steel box method requires pre-embedding steel boxes at both ends of the beam frame before connecting the closure section's box body to the pre-embedded steel boxes, and then proceeding with the closure section construction.

[0004] In actual construction, the closure section steel box is hoisted to be aligned with the pre-embedded steel box, and then workers weld the pre-embedded steel box and the closure section steel box together. However, during the hoisting process, positioning is usually done manually, which can easily lead to deviations in the position between the closure section steel box and the pre-embedded steel box, resulting in welding errors and affecting the final construction effect. Utility Model Content

[0005] To address the aforementioned issues, this application provides a pre-embedded steel box structure for the closure segment of a continuous beam.

[0006] This application provides a pre-embedded steel box structure for the closure segment of a continuous beam, which adopts the following technical solution: A pre-embedded steel box structure for the closure section of a continuous beam includes a closure section box and two pre-embedded section boxes arranged opposite each other. The two pre-embedded section boxes are each arranged on a beam frame. A plurality of positioning plates are provided at one end of the closure section box near the pre-embedded section box, and each positioning plate abuts against the pre-embedded section box at the corresponding position.

[0007] By adopting the above technical solution, when the closure segment box is required, workers hoist it between the two pre-embedded segment boxes. Once the positioning plate abuts against the pre-embedded segment box, workers can then weld the closure segment box to it. At this point, the positioning plate improves the positional accuracy between the closure segment box and the pre-embedded segment box, reducing the possibility of welding deviations and thus improving subsequent construction results.

[0008] Preferably, the closure section box body has a first welding slope on the side near the pre-embedded section box body, and the pre-embedded section box body has a second welding slope that cooperates with the first welding slope on the side near the closure section box body.

[0009] By adopting the above technical solution, the first welding bevel and the second welding bevel facilitate workers in determining the welding position, while increasing the contact area between the solder and the closure section box and the pre-embedded section box, thereby improving the welding stability between the closure section box and the pre-embedded section box.

[0010] Preferably, it also includes a reinforcing box, which is disposed on the inner side of the closure segment box and is connected to the closure segment box through a positioning component.

[0011] By adopting the above technical solutions, the reinforcement of the box body improves the overall structural strength of the subsequent closure section, thereby further improving the construction effect of the closure section.

[0012] Preferably, the positioning component includes a positioning seat, a positioning post, and a positioning cylinder. The positioning seat is disposed on the closure section box, the positioning post is disposed on the positioning seat, and the positioning cylinder is disposed on the side of the reinforcing box close to the closure section box. The positioning post extends into the positioning cylinder.

[0013] By adopting the above technical solution, during the installation of the reinforcing box, workers hoist the reinforcing box into the closure section box, aligning the positioning cylinder with the positioning column. Workers then continue to control the movement of the reinforcing box, causing the positioning column to insert into the positioning cylinder, while the positioning cylinder abuts against the positioning seat, thus completing the assembly between the reinforcing box and the closure section box.

[0014] Preferably, the closure section box body is provided with a first support, and the reinforcement box body is provided with a second support opposite to the first support. The first support and the second support are provided with reinforcement blocks. One end of the reinforcement block abuts against the closure section box body, and the other end abuts against the reinforcement box body. The reinforcement block is connected to the first support and the second support by bolts.

[0015] By adopting the above technical solution, after the reinforcement box is installed, workers install the reinforcement blocks on the first support and the second support. At this time, under the action of the first support, the reinforcement blocks, and the second support, the internal structural strength of the completed closure section is improved, thereby further improving the construction effect at the closure section.

[0016] Preferably, both the closure section box and the reinforced box are equipped with reinforcing ribs.

[0017] Preferably, both the closure section box and the reinforcing box are provided with through holes for the prestressed steel bars to pass through.

[0018] In summary, this application includes at least one of the following beneficial technical effects: By setting up positioning plates, it is easier to determine the position between the closure section box and the pre-embedded section box, which improves the welding accuracy between the closure section box and the pre-embedded section box, thereby improving the final construction effect at the closure section. By setting the first welding slope and the second welding slope, the contact area between the solder and the embedded section box and the closure section box is increased, thereby improving the welding accuracy between the embedded section box and the closure section box. By setting up a reinforced box, which works in conjunction with the closure section box, the internal structural strength of the closure section is improved. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0022] This application discloses an embedded steel box structure for the closure segment of a continuous beam. (Refer to...) Figure 1 and Figure 2 A pre-embedded steel box structure for the closure section of a continuous beam includes a closure section box 1 and two oppositely arranged pre-embedded section boxes 2. The two oppositely arranged pre-embedded section boxes 2 are both pre-embedded in the beam frame at corresponding positions, with the closure section box 1 located between the two pre-embedded section boxes 2. Several positioning plates 3 are fixed to the side of the closure section box 1 closest to the pre-embedded section box 2, and each positioning plate 3 abuts against the corresponding pre-embedded section box 2. In this way, the positioning plates 3 facilitate the determination of the position between the closure section box 1 and the pre-embedded section box 2, reducing the occurrence of welding deviations and thus improving the final construction effect at the closure section.

[0023] Reference Figure 2To improve the connection stability between the closure segment box 1 and the pre-embedded segment box 2, a first welding bevel 11 is provided on the side of the closure segment box 1 closest to the pre-embedded segment box 2, and a second welding bevel 21 is provided on the side of the pre-embedded segment box 2 closest to the closure segment box 1, which cooperates with the first welding bevel 11. At this time, under the action of the first welding bevel 11 and the second welding bevel 21, the contact area between the weld and the pre-embedded segment box 2 and the closure segment box 1 is increased, thereby improving the welding accuracy between the pre-embedded segment box 2 and the closure segment box 1, and facilitating the subsequent pouring of the closure segment.

[0024] Reference Figure 1 To improve the final structural strength of the closure section, a reinforcing box 4 is provided in the closure section box 1.

[0025] The reinforcing housing 4 is connected to the closure section housing 1 via a positioning assembly 5. The positioning assembly 5 includes a positioning seat 51, a positioning post 52, and a positioning cylinder 53. The positioning seat 51 is disposed on the closure section housing 1, and the positioning post 52 is disposed on the positioning seat 51. The positioning cylinder 53 is disposed on the side of the reinforcing housing 4 near the closure section housing 1, and the positioning post 52 extends into the positioning cylinder 53.

[0026] After the welding of the closure section box 1 and the pre-embedded section box 2 is completed, the workers hoist the reinforcing box 4 into the closure section box 1, so that the positioning cylinder 53 is aligned with the positioning column 52. The workers then continue to control the movement of the reinforcing box 4, so that the positioning column 52 is inserted into the positioning cylinder 53. After the positioning cylinder 53 abuts against the positioning seat 51, the assembly between the reinforcing box 4 and the closure section box 1 is completed. After the reinforcing box 4 is installed, the workers pour concrete for the closure section. At this time, the internal structural strength of the closure section is improved by the action of the reinforcing box 4.

[0027] Reference Figure 1 The closure section box 1 is provided with a first support 12, and the reinforcement box 4 is provided with a second support 41 opposite to the first support 12. The first support 12 and the second support 41 are provided with reinforcement blocks 6. One end of the reinforcement block 6 abuts against the closure section box 1, and the other end abuts against the reinforcement box 4. The reinforcement block 6 is connected to the first support 12 and the second support 41 by bolts.

[0028] After the reinforcement box 4 is installed, the workers install the reinforcement block 6 on the first support 12 and the relief support. At this time, under the action of the first support 12, the reinforcement block 6 and the second support 41, the internal structural strength of the completed closure section is improved, thereby further improving the construction effect at the closure section.

[0029] Reference Figure 1Both the closure section box 1 and the reinforced box 4 are equipped with reinforcing bars 7, and both the closure section box 1 and the reinforced box 4 are provided with through holes 8 for the prestressed steel bars to pass through.

[0030] The reinforcing bar 7 improves the structural strength of the closure section box 1 and the embedded section box 2, reducing the possibility of deformation during the pouring of the closure section. At the same time, the through hole 8 facilitates the passage of prestressed steel bars inside the beam frame.

[0031] The implementation principle of the pre-embedded steel box structure for the closure section of a continuous beam in this embodiment is as follows: the position between the closure section box 1 and the pre-embedded section box 2 is determined by the positioning plate 3, which improves the positional accuracy between the closure section box 1 and the pre-embedded section box 2, and facilitates the fixing between the closure section box 1 and the pre-embedded section box 2, thereby improving the final construction effect.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
