[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] An embodiment of the present application provides an integral sliding device for the outer formwork of a cantilevered beam, which can solve the problem in the related art that when installing the box beam formwork, the outer formwork needs to be repeatedly disassembled and hoisted, which affects the construction efficiency.

[0028] See also Figures 1 to 3 As shown, an embodiment of the present application provides an integral sliding device for the outer side mold of a cantilever beam box, comprising a guide beam 6, a lifting mechanism and a traction mechanism, wherein the guide beam 6 is arranged throughout the inside of the outer side mold 7 and protrudes from the front and rear ends of the outer side mold 7 along the length direction of the outer side mold 7; the lifting mechanism comprises a main beam 1 fixedly arranged on the top of the box beam body 8 and a hanger 5 fixedly connected to the main beam 1, the guide beam 6 is arranged on the hanger 5 and can slide along the hanger 5; the traction mechanism is used to make the guide beam 6 slide along the lifting mechanism.

[0029] In actual use, the guide beam 6 can be driven to slide along the hanger 5 through the traction mechanism, and the guide beam 6 is set inside the outer mold 7 and protrudes from the front and rear ends of the outer mold 7 along the length direction of the outer mold 7. When the position of the outer mold 7 needs to be adjusted, the outer mold 7 rack is unloaded to the guide beam 6 as a whole, and the traction mechanism can be used to drive the guide beam 6 to slide, so that the outer mold 7 unloaded to the guide beam 6 can be moved as a whole. In this process, it is only necessary to unload the outer mold 7 rack as a whole onto the guide beam 6, and then move the guide beam 6 to slide along the hanger 5, so as to achieve the overall sliding of the outer mold 7, which can avoid the problem of repeated disassembly and hoisting of the outer mold 7 in traditional construction, which affects the construction efficiency.

[0030] Specifically, the traction mechanism can be a fall chain, through which the guide beam 6 slides along the hanger 5, and the outer mold 7 frame is unloaded onto the guide beam 6 as a whole. As the guide beam 6 slides, the outer mold 7 as a whole will also slide accordingly. This operation process is relatively simple and can improve the efficiency of moving the outer mold 7, thereby improving the efficiency of box beam installation.

[0031] In the traditional box girder side formwork installation construction, it is necessary to repeatedly dismantle the outer side formwork 7 and then hoist it. This process is cumbersome and complicated, which will affect the overall construction efficiency. In addition, the template of the outer side formwork 7 is prone to collision and deformation with the suspended beam body, affecting the quality and safety of the suspended beam body. The sliding device of the present application can facilitate the movement of the outer side formwork 7, improve the overall construction efficiency, and ensure the stability of the installation of the outer side formwork 7, avoiding quality problems such as misalignment caused by repeated disassembly and assembly of the outer side formwork 7. When the construction area is limited, the traditional construction method will bring inconvenience to the disassembly and installation of the outer side formwork 7. The device of the present application occupies a small space as a whole and can be suitable for use when the construction area is limited.

[0032] In some alternative embodiments, see Figure 1 and Figure 2 As shown, the embodiment of the present application provides an overall sliding device for the outer mold of a cantilever beam box. Through the traction mechanism, the guide beam 6 can be driven to slide along the hanger 5. The guide beam 6 is arranged inside the outer mold 7 and protrudes from the front and rear ends of the outer mold 7 along the length direction of the outer mold 7. When the position of the outer mold 7 needs to be adjusted, the outer mold 7 rack is unloaded onto the guide beam 6 as a whole. The traction mechanism can be used to drive the guide beam 6 to slide, so that the outer mold 7 unloaded onto the guide beam 6 can be moved as a whole. In this process, it is only necessary to unload the outer mold 7 rack as a whole onto the guide beam 6, and then move the guide beam 6 to slide along the hanger 5, so as to achieve the overall sliding of the outer mold 7, which can avoid the problem of repeatedly disassembling and hoisting the outer mold 7 in traditional construction, which affects the construction efficiency.

[0033] In actual use, the main beam 1 and the hanger 5 are connected by a fixed connector 4. In actual use, the fixed connector 4 is a fine-rolled threaded steel bar. The main beam 1 is arranged on the top of the box beam body 8, and the main beam 1 and the hanger 5 are connected by the fine-rolled threaded steel bar, so that the main beam 1 can stably lift the hanger 5. In some use cases, a plurality of anchor beams 2 are fixedly arranged on the top of the main beam 1, and the anchor beams 2 are anchored to the box beam body 8. The structural stability of the main beam 1 can be improved, and the main beam 1 can be prevented from overturning, so that the hanger 5 can be stably lifted, so that the hanger 5 can better withstand the gravity of the guide beam 6 and the outer mold 7, and can ensure that when the guide beam 6 and the outer mold 7 slide along the hanger 5 as a whole, the stability of the hanger 5 is improved.

[0034] In some optional embodiments, such as Figure 2 and Figure 3 As shown, a plurality of cushion beams 3 are arranged at the bottom of the main beam 1. The plurality of cushion beams 3 are perpendicular to the main beam 1 and serve as a structure for supporting the main beam 1 to prevent the main beam 1 from being deformed by force and ensure the stability of the structure.

[0035] In actual use, multiple groups of hangers 5 can be provided, and rollers are provided on the hangers 5 to assist the guide beam 6 in sliding. This arrangement can facilitate the guide beam 6 to slide along the hangers 5, thereby facilitating the movement of the outer mold 7.

[0036] In some optional embodiments, the main beam 1 is provided with a plurality of openings for passing the fine-rolled threaded steel bars. The anchor beam 2 is provided with a plurality of openings for passing the fine-rolled threaded steel bars, and a nut for matching the fine-rolled threaded steel bars is provided on the top of the anchor beam 2. The nuts can be used to fix the main beam 1 and the anchor beam 2 by the fine-rolled threaded steel bars. The provision of the fine-rolled threaded steel bars can tightly fix the main beam 1 and the anchor beam 2, and the anchor beam 2 is anchored to the box beam body 8, thereby improving the stability of the overall structure and strengthening the rigidity of the component.

[0037] The guide beam 6 can be driven to slide along the hanger 5 by the traction mechanism, and the guide beam 6 is set inside the outer mold 7 and protrudes from the front and rear ends of the outer mold 7 along the length direction of the outer mold 7. When the position of the outer mold 7 needs to be adjusted, the outer mold 7 rack is unloaded to the guide beam 6 as a whole, and the traction mechanism can be used to drive the guide beam 6 to slide, so that the outer mold 7 unloaded to the guide beam 6 can be moved as a whole. In this process, it is only necessary to unload the outer mold 7 rack as a whole onto the guide beam 6, and then move the guide beam 6 to slide along the hanger 5, so that the outer mold 7 can slide as a whole. A plurality of anchor beams 2 are fixedly arranged on the top of the main beam 1, and the anchor beams 2 are anchored to the box beam body 8. It can improve the structural stability of the main beam 1 and prevent the main beam 1 from overturning, so as to stably hoist the hanger 5, so that the hanger 5 can better withstand the gravity of the guide beam 6 and the outer mold 7, and can ensure that when the guide beam 6 and the outer mold 7 slide along the hanger 5 as a whole, the stability of the hanger 5 is improved. A plurality of cushion beams 3 are arranged at the bottom of the main beam 1, and the plurality of cushion beams 3 are perpendicular to the main beam 1. As a structure supporting the main beam 1, it prevents the main beam 1 from being deformed by force and ensures the stability of the structure.

[0038] In actual use, I-beams are provided at both ends of the guide beam 6 to prevent the guide beam 6 from slipping. After the guide beam 6 is installed in place, I-beams can be welded at both ends of the guide beam 6 as limit devices to prevent the guide beam 6 from slipping.

[0039] Specifically, the finely rolled threaded steel and PVC pipe are embedded before the concrete pouring of the previous section. After the beam body is poured, the main beam 1 and the anchor beam 2 are installed. The hole in the middle of the main beam 1 passes through the finely rolled threaded steel and is tightened and anchored with the anchor beam 2 using nuts. The guide beam 6 is hung by the hanger 5, and the hanger 5 is connected to the main beam 1 and the anchor beam 2 by the finely rolled threaded steel through the embedded PVC pipe. After the guide beam 6 is installed in place, I-beams are welded at both ends of the guide beam 6 as a limit device to prevent the guide beam 6 from slipping.

[0040] After that, the outer mold 7 is unloaded as a whole onto the guide beam 6, and the guide beam 6 is pulled by the traction mechanism, so that the guide beam 6 slides along the hanger 5, so that the outer mold 7 slides as a whole. The hanger 5 can be provided with rollers to facilitate sliding. After the outer mold 7 slides into place, the hanger 5 is released and converted to the fine-rolled threaded steel and the nuts and washers are tightened and fixed under the guide beam 6. The anchor beam 2 is lifted by the supporting jack to adjust the fine-rolled threaded steel to adjust the elevation and slope of the outer mold 7. After the template is adjusted, the template flatness and other quality inspections are carried out, and then the next construction process is entered.

[0041] The traction mechanism can be a fall chain, through which the guide beam 6 slides along the hanger 5, and the outer mold 7 frame is unloaded onto the guide beam 6 as a whole. As the guide beam 6 slides, the outer mold 7 as a whole will also slide accordingly. This operation process is relatively simple and can improve the efficiency of moving the outer mold 7, thereby improving the efficiency of box beam installation.

[0042] In the traditional box girder side formwork installation construction, it is necessary to repeatedly dismantle the outer side formwork 7 and then hoist it. This process is cumbersome and complicated, which will affect the overall construction efficiency. In addition, the template of the outer side formwork 7 is prone to collision and deformation with the suspended beam body, affecting the quality and safety of the suspended beam body. The sliding device of the present application can facilitate the movement of the outer side formwork 7, improve the overall construction efficiency, and ensure the stability of the installation of the outer side formwork 7, avoiding quality problems such as misalignment caused by repeated disassembly and assembly of the outer side formwork 7. When the construction area is limited, the traditional construction method will bring inconvenience to the disassembly and installation of the outer side formwork 7. The device of the present application occupies a small space as a whole and can be suitable for use when the construction area is limited.
