Abstract
Description
Technical Field
[0001] This application relates to the field of bridge reinforcement technology, and in particular to a suspended hanger for bridge reinforcement construction. Background Technology
[0002] Currently, bridge reinforcement uses a variety of scaffolding systems, which are generally suitable for land areas under bridges. However, when the area under a bridge is a river or tidal flat, it is impossible to provide installation and load-bearing capacity on the ground or in the water, and it will also affect the passage of ships. When using a scaffolding system, hooks need to be installed on the T-beam by installing rebar, and steel wire ropes are used as lifting components to suspend the transverse steel pipes under the T-beam plate. Then, a platform is built, and workers reinforce the bridge on the platform. This method makes the overall scaffolding system prone to instability, and workers operating on the platform are prone to swaying, affecting the safety of reinforcement. Summary of the Invention
[0003] To address the aforementioned problems, this application provides a suspended hanger for bridge reinforcement construction.
[0004] This application provides a suspended hanger for bridge reinforcement construction, which adopts the following technical solution: A suspended scaffold for bridge reinforcement construction is applied to the T-beam horseshoe section of a bridge. It includes platform members and beam-mounted members, the beam-mounted members being snapped into the T-beam horseshoe section, and the platform members being connected to the bottom of the beam-mounted members. The platform members include platform crossbars and platform longitudinal bars, which are cross-connected. The beam-mounted members include beam-mounted hanging rods and beam-mounted crossbars, the beam-mounted crossbars spanning between the two T-beam horseshoe sections for snapping, the beam-mounted hanging rods connecting to the beam-mounted crossbars, extending below the platform crossbars and platform longitudinal bars, and connecting to the intersection point between the platform crossbars and platform longitudinal bars.
[0005] By adopting the above technical solution, the horizontal bar on the beam is connected to the two horseshoe-shaped parts of the T-beam, and one end of the beam hanger is connected to the horizontal bar on the beam, while the other end is connected to the intersection of the platform horizontal bar and the platform longitudinal bar. This allows workers to stand on the platform horizontal bar or the platform longitudinal bar to process the bridge. The beam hanger provides stable force, which is then transmitted to the horseshoe-shaped parts of the T-beam through the beam horizontal bar, thus ensuring the stability of the overall suspended scaffold.
[0006] Optionally, it also includes bridge struts located between the guardrails of the two bridge decks, extending downwards from the bridge and connecting to the platform struts.
[0007] By adopting the above technical solution, the bridge-mounted members provide partial support for the platform members. The bridge-mounted members are located between the guardrails of the two bridge decks and extend from the reserved space between adjacent bridges to the underside of the bridge, connecting with the platform members, thereby achieving stable support for the platform members and further improving the stability of the overall suspended scaffold.
[0008] Optionally, the bridge members include bridge crossbars, bridge longitudinal bars, and bridge hangers; the bridge crossbars span the guardrails of both bridge decks; the bridge longitudinal bars intersect with the bridge crossbars and extend along the direction of the bridge deck; the bridge hangers are connected at the intersection of the bridge longitudinal bars and the bridge crossbars, and extend downward to below the platform members, connecting with the intersection of the platform crossbars and the platform longitudinal bars.
[0009] By adopting the above technical solution, after the bridge suspenders are connected to the platform members, the force on the platform members is transmitted to the bridge longitudinal members and bridge transverse members through the bridge suspenders. In this way, the force is distributed to the guardrails on the bridge deck by the bridge longitudinal members and bridge transverse members, so as to provide a stable support effect.
[0010] Optionally, the two ends of the crossbar on the beam are further provided with unfolding structures, which are screwed to the crossbar on the beam.
[0011] By adopting the above technical solution, the unfolded structure is screwed to the crossbar on the beam, replacing the crossbar on the beam and being snapped to the horseshoe part of the T-beam. The unfolded size of the unfolded structure is large, which allows the force to be distributed to the horseshoe part of the T-beam, thereby further improving the stability of the connection.
[0012] Optionally, the unfolding structure includes a trapezoidal block, a pivot bearing, and a pivot steel pipe; the inner diameter of the pivot steel pipe matches the outer diameter of the crossbar on the beam, the outer wall of the crossbar on the beam is provided with external threads, and the inner wall of the pivot steel pipe is provided with internal threads, so that the pivot steel pipe is screwed to the crossbar on the beam; the pivot bearing is installed on the trapezoidal block, and the pivot steel pipe is pivotally connected to the pivot bearing.
[0013] By adopting the above technical solution, the spacing width of the T-beam's horseshoe section can be adjusted by rotating the pivot steel pipe. The pivot steel pipe can rotate along the pivot bearing, and during the rotation, it can move along the crossbar on the beam through the internal and external threads, thereby realizing the length adjustment of the crossbar on the beam and the unfolded structure. This ensures that the trapezoidal block can be stably placed at the T-beam's horseshoe section. The trapezoidal block increases the contact area with the T-beam's horseshoe section, thereby dispersing the force and preventing the T-beam's horseshoe section from being crushed.
[0014] Optionally, the trapezoidal block is further provided with a threaded hole, and the pivoting steel pipe extends into the trapezoidal block through the pivoting bearing and is located at the threaded hole; a locking bolt is screwed into the threaded hole, and the locking bolt passes through the threaded hole and presses against the pivoting steel pipe.
[0015] By adopting the above technical solution, as the locking bolt rotates continuously along the threaded hole, it descends into the insertion hole and contacts the outer wall of the pivoting steel pipe. As the locking bolt is pressed against the outer wall of the pivoting steel pipe, the pivoting steel pipe cannot rotate, thus providing a certain degree of stability.
[0016] Optionally, a perforated steel plate is also laid between the platform crossbar and the platform longitudinal bar.
[0017] By adopting the above technical solution, the perforated steel plate can fill the gap between the platform's horizontal and vertical bars, allowing workers to step on the perforated steel plate, making their movements more convenient and flexible, and eliminating concerns about falling off the platform members, thus providing a certain level of safety.
[0018] Optionally, a connecting fastener is provided at the intersection connection point. The connecting fastener is a right-angle fastener or a swivel fastener, and the various rods are cross-connected by the right-angle fastener or the swivel fastener.
[0019] By adopting the above technical solution, right-angle fasteners or swivel fasteners are used to connect all the required cross-connection members of the platform members, beam members, and bridge members, thereby ensuring the stability of the overall suspended scaffold.
[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The horizontal bar on the beam is connected to the two horseshoe-shaped parts of the T-beam by snapping. One end of the beam hanger is connected to the horizontal bar on the beam, and the other end is connected to the intersection of the platform horizontal bar and the platform longitudinal bar. This allows workers to stand on the platform horizontal bar or the platform longitudinal bar to process the bridge. The beam hanger provides stable force, which is then transmitted to the horseshoe-shaped parts of the T-beam through the beam horizontal bar, thus ensuring the stability of the overall suspended scaffold. 2. The bridge-mounted members provide partial support for the platform members. The bridge-mounted members are located between the guardrails of the two bridge decks and extend from the reserved space between adjacent bridges to the underside of the bridge, connecting with the platform members to achieve stable support for the platform members and further improve the stability of the overall suspended scaffold. 3. After the bridge hangers are connected to the platform members, the force on the platform members is transferred to the bridge longitudinal members and bridge transverse members through the bridge hangers. The bridge longitudinal members and bridge transverse members then distribute the force to the guardrail on the bridge deck to provide a stable support effect. 4. After the unfolded structure is screwed to the crossbar on the beam, it replaces the crossbar on the beam and is snapped into the horseshoe part of the T-beam. The unfolded size of the unfolded structure is large, which allows the force to be distributed in the horseshoe part of the T-beam, thereby further improving the stability of the connection.

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0028] This application discloses a suspended hanger for bridge reinforcement construction.
[0029] A suspended hanger for bridge reinforcement construction, reference Figure 1 and Figure 2 As shown, the T-beam horseshoe section 1 applied to the bridge refers to the key area of the prestressed concrete T-beam structure set at a preset distance between bridges. It is used to adapt to the arrangement requirements of prestressing tendons, increase the bearing capacity by expanding the lower edge section, and optimize the section efficiency.
[0030] The suspended scaffold includes platform members 2 and upper beam members 3. Upper beam members 3 are used to provide load-bearing capacity, so upper beam members 3 are engaged with the T-beam horseshoe part 1, using the T-beam horseshoe part 1 as the load-bearing point. Platform members 2 are used to build a platform for workers to move around. The bottom of platform members 2 is connected to the upper beam members 3, allowing workers to move on platform members 2. The upper beam members 3 provide load-bearing capacity, and the force is then transferred to the T-beam horseshoe part 1 to ensure the stability of the load.
[0031] Platform member 2 includes several platform horizontal bars 21 and several platform vertical bars 22. The platform horizontal bars 21 and platform vertical bars 22 are cross-connected. There are several platform horizontal bars 21 and several platform vertical bars. The specific number is determined according to the length and width of the bridge to be reinforced and is not limited here. Several platform horizontal bars 21 and several platform bars are laid and connected in a cross pattern to form a mobile platform for workers. Workers can step on the platform horizontal bars 21 and platform vertical bars 22 to carry out bridge reinforcement construction.
[0032] The beam member 3 includes beam hangers 32 and beam crossbars 31. Several beam hangers 32 and beam crossbars 31 are provided, and the specific number is determined according to the requirements. The beam crossbars 31 span between the two T-beam horseshoe parts 1 to achieve a snap-fit connection. Several beam crossbars 31 are set at preset intervals to ensure the stability of the load. The beam hangers 32 are connected to the beam crossbars 31. The beam hangers 32 extend to the bottom of the platform crossbars 21 and platform longitudinal bars 22, and connect with the intersection connection point between the platform crossbars 21 and platform longitudinal bars 22, thereby providing support for the platform crossbars 21 and platform longitudinal bars 22 to ensure the stability of the load. The entire platform member 2 will not sway when workers walk on it, so that workers can carry out bridge reinforcement construction operations smoothly.
[0033] In some embodiments, reference Figure 1 As shown, it also includes bridge support members 4. Some large bridges are constructed by building two or more bridges side by side to separate traffic. There is a gap between the two bridge decks. Therefore, the bridge support members 4 are set to provide some support or load-bearing capacity. Guardrails 5 are installed on the top of the side beams of the bridge. The guardrails 5 can prevent pedestrians or vehicles from falling out and provide safety. The bridge support members 4 are located between the guardrails 5 of the two bridge decks and extend from the reserved space between the adjacent bridges to the bridge deck and connect with the platform support members 2, thereby achieving stable support for the platform support members 2 and further improving the stability of the overall suspended scaffold.
[0034] Further reference Figure 1 As shown, the bridge members 4 include bridge crossbars 41, bridge longitudinal bars 42 and bridge hangers 43; the bridge crossbars 41 span across the guardrails 5 on both bridge decks, thereby utilizing the guardrails 5 on both bridge decks for support.
[0035] The longitudinal bars 42 and the transverse bars 41 on the bridge are connected at intersection. At least two longitudinal bars 42 can be set, corresponding to the two guardrails 5. If the reserved space between the two bridge decks is large, additional longitudinal bars 42 can be set. The longitudinal bars 42 extend along the extension direction of the bridge deck. If the length of the longitudinal bar 42 is insufficient, another longitudinal bar 42 can be used to overlap it to extend the overall length. Several transverse bars 41 are set. They can be set at preset intervals according to requirements. The specific preset interval is based on the analysis of the stress conditions and is not limited here.
[0036] The bridge hanger 43 is connected to the intersection of the bridge longitudinal member 42 and the bridge transverse member 41, and extends downward to the bottom of the platform member 2, connecting with the intersection of the platform transverse member 21 and the platform longitudinal member 22. After the bridge hanger 43 is connected to the platform member 2, the force on the platform member 2 is transmitted to the bridge longitudinal member 42 and the bridge transverse member 41 through the bridge hanger 43, thereby distributing the force to the guardrail 5 on the bridge surface through the bridge longitudinal member 42 and the bridge transverse member 41 to provide a stable support effect.
[0037] Furthermore, if the heights of the guardrails 5 on the bridge deck are inconsistent, vertical poles can be installed on the bridge. One end of the vertical pole is connected to the horizontal pole 41 on the bridge to provide support for the horizontal pole 41, and the other end stands vertically and abuts against the bridge deck to achieve a supporting function, so as to adapt to the situation where the heights of the guardrails 5 are inconsistent.
[0038] In some embodiments, reference Figure 3 and Figure 4 As shown, when the upper crossbar 31 is engaged with the T-beam horseshoe portion 1, the contact point between the upper crossbar 31 and the T-beam horseshoe portion 1 is small. Under excessive force, the T-beam horseshoe portion 1 is easily damaged, causing irreversible damage. Therefore, an unfolding structure 6 is provided at both ends of the upper crossbar 31. The unfolding structure 6 is screwed to the upper crossbar 31, replacing the engagement between the upper crossbar 31 and the T-beam horseshoe portion 1. The unfolding size of the unfolding structure 6 is large, so that the force can be distributed to the T-beam horseshoe portion 1, thereby further improving the stability of the connection.
[0039] Further reference Figure 4 and Figure 5 As shown, the unfolding structure 6 includes a trapezoidal block 61, a pivot bearing 62, and a pivot steel pipe 63. The trapezoidal block 61 can be made of plastic, wood, or metal as required. The trapezoidal block 61 has an insertion hole in the middle. The pivot bearing 62 is fixedly installed at the insertion hole, which extends into the trapezoidal block 61 to form an extended space into which the pivot steel pipe 63 can extend.
[0040] The inner diameter of the pivoting steel pipe 63 matches the outer diameter of the upper crossbar 31. Matching means that the inner diameter of the pivoting steel pipe 63 is the same as or slightly larger than the outer diameter of the upper crossbar 31. The outer wall of the upper crossbar 31 is provided with external threads, and the inner wall of the pivoting steel pipe 63 is provided with internal threads, so that the upper crossbar 31 can be inserted into the pivoting steel pipe 63 and screwed to it. According to the screwed position after the pivoting steel pipe 63 and the upper crossbar 31 are rotated and adjusted, the overall length of the upper crossbar 31 and the unfolding structure 6 can be adjusted, thereby adapting to the horseshoe part 1 of T-beams of different widths. The pivoting steel pipe 63 is pivotally connected to the pivoting bearing 62 and extends into the insertion hole.
[0041] Specifically, the spacing width of the T-beam horseshoe section 1 can be adjusted by rotating the pivot steel pipe 63. The pivot steel pipe 63 can rotate along the pivot bearing 62. During the rotation, it can move along the upper crossbar 31 of the beam through the internal and external threads, thereby realizing the length adjustment of the upper crossbar 31 of the overall beam and the unfolded structure 6. This ensures that the trapezoidal block 61 can be stably placed at the T-beam horseshoe section 1. By using the trapezoidal block 61 to increase the contact area with the T-beam horseshoe section 1, the force is distributed to avoid the T-beam horseshoe section 1 being crushed.
[0042] Furthermore, refer to Figure 4 and Figure 5 As shown, the trapezoidal block 61 is also provided with a threaded hole 611. The pivoting steel tube 63 extends through the pivoting bearing 62 into the trapezoidal block 61 to the threaded hole 611. That is, the pivoting steel tube 63 is inserted into the insertion hole after passing through the pivoting bearing 62. The insertion hole is connected to the threaded hole 611, so that the threaded hole 611 is located above the insertion hole. A locking bolt 64 is screwed into the threaded hole 611. The locking bolt 64 passes through the threaded hole 611 and presses against the pivoting steel tube 63. As the locking bolt 64 rotates continuously along the threaded hole 611, the locking bolt 64 continuously descends into the insertion hole and contacts the outer wall of the pivoting steel tube 63. As the locking bolt 64 is pressed against the outer wall of the pivoting steel tube 63, the pivoting steel tube 63 cannot rotate, thereby providing a certain degree of stability.
[0043] When it is necessary to disassemble or adjust the position of the trapezoidal block 61, loosening the locking bolt 64 will release the pivot steel pipe 63, which can then rotate along the pivot bearing 62, thereby adjusting the position of the crossbar 31 on the beam.
[0044] The contact point between the pivoting steel pipe 63 and the locking bolt 64 may be provided with friction grooves. When the locking bolt 64 contacts the friction grooves, the friction force can be increased, further preventing the pivoting steel pipe 63 from rotating.
[0045] Among them, all members of the platform member 2, beam member 3, and bridge member 4 can be made of steel pipe, with stainless steel alloy pipe being preferred.
[0046] In some embodiments, reference Figure 2 As shown, a perforated steel plate 23 is also laid between the platform crossbar 21 and the platform longitudinal bar 22. The perforated steel plate 23 can fill the gap between the platform crossbar 21 and the platform longitudinal bar 22, allowing workers to step on the perforated steel plate 23, making it easier for workers to move and more flexible, and they don't have to worry about falling off the platform bar 2, thus providing a certain degree of safety.
[0047] Further reference Figure 1 and Figure 2As shown, right-angle fasteners or swivel fasteners are provided at the cross connection points. The various rods are cross-connected by right-angle fasteners or swivel fasteners. All the rods that need to be cross-connected, such as platform rod 2, beam rod 3, and bridge rod 4, are connected to each other by right-angle fasteners or swivel fasteners, thereby ensuring the stability of the overall suspended scaffold.
[0048] Furthermore, platform railings can be installed along the edges of the platform crossbars 21 and platform longitudinal bars 22 to improve safety.
[0049] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
