Description

Technical Field

[0001] The utility model relates to the field of bridge construction auxiliary equipment, in particular to a fully enclosed hanging basket protection structure for bridge construction. Background Art

[0002] The main truss of the hanging basket hangs on the hanging basket formwork so that the bridge can be constructed in sections. It is the core equipment for the construction of prestressed concrete continuous beams, T-shaped steel structures and cantilever beams. In view of the high-altitude characteristics of the hanging basket construction, the installation of anti-fall nets is essential to ensure the safety of construction workers. However, falling materials and tools during the construction process may cause damage to the net surface. If it is not replaced in time, the net surface may break when it carries the falling object again, causing safety hazards. Therefore, it is very important to replace the anti-fall net in time. At present, most construction teams tie the anti-fall net directly to the scaffolding on the outside of the bridge. The installation and disassembly process is cumbersome, which will increase the labor intensity of workers and affect the construction progress. Summary of the invention

[0003] The utility model provides a fully enclosed hanging basket protection structure for bridge construction, so as to reduce the labor intensity of workers and speed up the construction progress.

[0004] In order to achieve the above purpose, the technical solution of the utility model is:

[0005] A fully enclosed hanging basket protection structure for bridge construction, comprising: a main truss protection structure;

[0006] The main truss protection structure comprises a primary anti-falling net installation block and a primary anti-falling net, wherein the primary anti-falling net installation block can be hung on the main truss through an eye hook, and a slide groove is provided on the primary anti-falling net installation block;

[0007] One end of the first-level anti-falling net is provided with a sliding rod which can be inserted into the sliding groove, and the other end of the first-level anti-falling net can be hung on the hanging basket template through an eye hook.

[0008] Furthermore, the main truss protection structure also includes a transition net and a secondary anti-falling net, and the secondary anti-falling net is located below the primary anti-falling net;

[0009] One end of the secondary anti-falling net can be hung on the hanging basket template through an eye hook, and the other end of the secondary anti-falling net is provided with a transition net mounting block, and the transition net mounting block is provided with a transition net slide groove;

[0010] One end of the transition net can be hung on the primary anti-fall net through an eye hook, and the other end of the transition net is provided with a transition net slide bar which can be inserted into the transition net slide groove.

[0011] Furthermore, it also includes a bottom walking channel protection net, which includes a frame and a protective soft net tied to the frame, and the frame is hung on the bottom walking channel through eye hooks.

[0044] Example 1

[0045] For better explanation, a hanging basket structure suitable for a cable-stayed bridge is introduced below. Figure 1 As shown, the main truss 1 of the hanging basket structure includes a crossbeam, and the crossbeam includes a main crossbeam 2 and a secondary crossbeam 3 arranged at both ends of the main crossbeam 2. The secondary crossbeam 3 hangs the hanging basket template 12 through a steel sling 13 with hooks at both ends, so that the hanging basket template 12 can move forward and backward together with the crossbeam. The main crossbeam 2 and the secondary crossbeam 3 are detachably connected by bolts. During the forward movement and closing process of the hanging basket structure, the main crossbeam 2 and the secondary crossbeam 3 are not separated. During the backward movement of the hanging basket structure, the main crossbeam 2 and the secondary crossbeam 3 are separated. The separated secondary crossbeam 3 is supported by a lifting device, so that the inclined cable A can pass through the separation point between the main crossbeam 2 and the secondary crossbeam 3, so as to prevent the inclined cable A from interfering with the crossbeam during the process of the hanging basket structure retreating to the two ends of the cable-stayed bridge. The utility model can be applied to the above-mentioned hanging basket structure, and can also be applied to the hanging basket structure in which the crossbeam of the conventional main truss 1 is an integrated design;

[0046] This embodiment provides a fully enclosed hanging basket protection structure for bridge construction, including: a main truss protection structure;

[0047] Figure 1 and Figure 2 As shown, the main truss protection structure includes a primary anti-falling net installation block 4 and a primary anti-falling net 5, as shown in FIG. Figure 5 As shown, the primary anti-falling net mounting block 4 can be hung on the steel structure of the secondary crossbeam 3 through the eye hook 8, and the primary anti-falling net mounting block 4 is provided with a slide groove 401. In this embodiment, the eye hook 8 is welded and fixed to the primary anti-falling net mounting block 4. In this embodiment, two rows of eye hooks 8 are provided on the primary anti-falling net mounting block 4 to ensure that the primary anti-falling net mounting block 4 can be stably installed on the secondary crossbeam 3;

[0048] like Figure 6 As shown, one end of the first-level anti-falling net 5 is welded with a slide bar 501 that can be inserted into the slide groove 401, and the other end of the first-level anti-falling net 5 is welded with a slide bar 501 that can be inserted into the slide groove 401. Fig. 9The eye hook 8 shown, the primary anti-fall net 5 is hung on the steel structure of the hanging basket template 12 through the eye hook 8;

[0049] The construction personnel insert the slide bar 501 into the slide groove 401, and hang the eye hook 8 of the primary anti-falling net 5 on the steel structure of the hanging basket template to achieve the installation of the primary anti-falling net 5;

[0050] Compared with the commonly used fixing form of directly tying the anti-fall net to the scaffolding on the outside of the bridge, the main truss protection structure is set to be easy to disassemble and assemble, so that it can be easily replaced after the net surface is damaged, thereby reducing the labor intensity of construction workers and improving construction efficiency. At the same time, since the main truss protection structure is directly installed on the main truss 1 and the hanging basket template 12, it can move with the main truss 1 and the hanging basket template 12. Construction workers do not need to continue to build the anti-fall net as the hanging basket structure moves forward, further reducing the labor intensity of construction workers.

[0051] In a specific embodiment, Figure 1 and Figure 2 As shown, the main truss protection structure also includes a transition net 6 and a secondary anti-falling net 7, and the secondary anti-falling net 7 is located below the primary anti-falling net 5;

[0052] like Figure 8 As shown, a ring eye hook 8 is welded at one end of the secondary anti-falling net 7, and the secondary anti-falling net 7 is hung on the steel structure of the hanging basket template 14 through the ring eye hook 8. A transition net mounting block 9 is welded at the other end of the secondary anti-falling net 7, and a transition net chute 901 is provided on the transition net mounting block 9;

[0053] like Figure 7 As shown, a ring eye hook 8 is welded at one end of the transition net 6, and the transition net 6 is hung on the primary anti-falling net 5 through the ring eye hook 8. A transition net slide bar 601 that can be inserted into the transition net slide groove 901 is welded at the other end of the transition net 6;

[0054] The construction personnel insert the transition net slide bar 601 into the transition net slide groove 901, and hang the eye hook 8 of the transition net 6 on the primary anti-falling net 5, and hang the eye hook 8 of the secondary anti-falling net 7 on the steel structure of the hanging basket template to achieve the installation of the transition net 6 and the secondary anti-falling net 7;

[0055] In actual use, the mesh size of the transition net 6 and the secondary anti-fall net 7 is smaller than that of the primary anti-fall net 5, so as to provide multiple protections for the construction personnel, construction materials and construction tools during the construction of the hanging basket structure, ensure the safety of the construction personnel, and avoid the negative impact of the accidental falling of various tools and construction materials during the construction process on the normal operation of the highway C under the cable-stayed bridge.

[0056] Example 2

[0057] In order to facilitate the installation of steel suspension straps 13 for construction workers, the disassembly and assembly of the formwork structure 12, etc., in actual construction, a bottom walking passage 10 is usually provided at the bottom of the hanging basket formwork 14. The bottom walking passage 10 is a three-sided surrounding structure, and the three-sided surrounding structure opens on one side facing away from the closure B of the cable-stayed bridge as shown in Fig.10 the figure.

[0058] This embodiment provides a fully enclosed hanging basket protection structure for bridge construction. The main structure of this embodiment is similar to that of Embodiment 1. The difference between this embodiment and Embodiment 1 is as follows:

[0059] In this embodiment, as shown in Figure 1 and Figure 3 the figure, it further includes a bottom walking passage protection net 11. As shown in Figure 4 the figure, the bottom walking passage protection net 11 includes a skeleton 1101 and a protective soft net 1102 tied to the skeleton 1101. The skeleton 1101 is hung on the bottom walking passage 10 through a steel wire rope 14 with eye hooks 8 fixed at both ends, so as to facilitate the installation and replacement of the bottom walking passage protection net 11;

[0060] By setting the "C"-shaped bottom walking passage protection net 11 as shown in Figure 3 the figure, it effectively prevents the construction workers on the bottom walking passage 10 of the three-sided surrounding structure from falling and the safety problems caused by the accidental falling of construction tools or construction materials;

[0061] The skeleton 1101 is a welded steel bar skeleton. In actual use, the first-level anti-falling net 5, the transition net 6, and the second-level anti-falling net 7 can all be composed of a steel bar skeleton and a protective soft net.

[0062] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
