Description

Technical Field

[0001] The utility model relates to the technical field of shield tunnel construction, in particular to a temporary storage bracket for shield segments. Background Art

[0002] With the continuous development of urbanization in my country, urban traffic volume has increased rapidly. The development of underground space can effectively solve the problem of urban traffic congestion. Among them, the shield method has been widely used as the main construction method in subway construction.

[0003] Since shield segments are usually prefabricated in factories, three pieces are stacked in a group, and small wooden blocks are used as pads between the segments and transported to the construction site. Therefore, some shield segments often need to be stored at the shield construction site. Shield segments are mostly circular, and placing them alone on the ground will cause certain deformation and wear, and the stability is poor. At present, the segment brackets made of square wood are commonly used in construction, but the segments placed on the square wood are in linear contact with the square wood, which leads to stress concentration and easily causes the outer arc surface of the segment to break, affecting the subsequent use of the segment; and the mass of the segment is large, if the bottom square wood is used for too long, it is easy to break; in addition, when ensuring stability, other existing bracket structures have a relatively fixed structure, which is difficult to disassemble and transport, and has certain limitations in use.

[0006] In the present technical solution, the bracket structure forms a frame structure through a supporting base frame and a connecting plate, which plays the role of temporarily and stably storing shield segments. The contact frame located at the upper end of the supporting base frame contacts the surface of the shield segment after chamfering, which is beneficial to increase the contact area with the shield segment and improve the storage stability. The bracket in the present technical solution is detachable as a whole, which is light during construction and convenient for turnover and transportation after construction. At the same time, the material required for bracket processing is less, the process is simple, and the processing cost is low.

[0017] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0018] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0019] like Figure 1 and Figure 2As shown, a specific embodiment of the utility model provides a temporary storage bracket for shield segments. The device is used for temporarily storing shield segment structures used for tunnel construction, which can improve storage stability and facilitate disassembly, assembly and turnover transportation. It specifically includes a pair of support frames 100 with H-shaped cross-sections, and the upper ends of the support frames 100 are provided with contact frames 200 arranged along the length of the support frames 100, and the opposite sides of the upper ends of the two contact frames 200 are provided with chamfered structures; the ends of the two support frames 100 are detachably connected by a connecting plate 300.

[0020] like Figure 1 and Figure 2 As shown, through the above arrangement, the bracket structure in this embodiment forms a frame structure through the supporting base frame 100 and the connecting plate 300 to play the role of temporarily and stably storing the shield segments. The contact frame 200 located at the upper end of the supporting base frame 100 contacts the surface of the shield segment after chamfering, which is beneficial to increase the contact area with the shield segment and improve the storage stability. Since the bracket is detachable as a whole, it is light and reliable during the construction process, and convenient for turnover and transportation after the construction is completed. In addition, the bracket requires less material for processing, has high structural strength, simple process, and low processing cost.

[0021] like Figure 1 and Figure 2 As shown, since the connecting plate 300 structure needs to be installed at both ends of the supporting base frame 100, in order to improve the installation stability of the connecting plate 300, in this embodiment, end plates 400 are fixed to the end faces of both ends of the supporting base frame 100, and the ends of the connecting plate 300 located at both ends of the supporting base frame 100 are fixed on the end plates 400. In this way, by setting the end plate 400 structure, it can be used as the installation surface of the connecting plate 300, which is conducive to improving the installation stability. In practical applications, a plurality of connecting holes 310 arranged horizontally at intervals are provided at both ends of the connecting plate 300. By setting the connecting holes 310, the spacing between the two supporting base frames 100 can be adjusted, and the connecting plate 300 and the end plate 400 can be fixed by bolts.

[0022] In production applications, the connecting plate 300 adopts an angle iron structure with an L-shaped cross-section; the supporting base frame 100 adopts an H-shaped steel structure, and the contact frame 200 is made of a nylon plate; the supporting base frame 100 adopts an H-shaped steel of 1500mm*150mm*150mm, and the end plate 400 adopts a steel plate of 150mm*150mm*10mm; the contact frame 200 adopts a nylon plate of 1460mm*80mm*40mm processed into a chamfered form; the connecting plate 300 is an angle iron of 1500mm*50mm*50mm; since the contact frame 200 is fixed to the upper end of the supporting base frame 100, this embodiment provides fixing holes 210 at both ends of the contact frame 200 so that the contact frame 200 can be fixed by bolts.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
