[0029] In response to the above problems, an embodiment of the present application provides an umbrella-shaped support structure for a circular deep foundation pit retaining wall concrete formwork. The technical solution of the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.
[0030] like Figure 1 and Figure 2 The circular deep foundation pit retaining wall concrete formwork umbrella-shaped support structure shown includes a formwork 5; and further includes:
[0031] Base 1, the base of the present application is set to be disc-shaped. During use, the entire base is first fixed thereon with expansion bolts. When the corners of the base are soft, cement is first poured into the stone piers for fixing. The present application also includes a central axis 2, which is set to be a circular axis. The middle and lower parts of the central axis 2 are set to be smooth columns for easy sliding, and the middle and upper parts are set to be threaded columns for easy threaded connection. The present application also includes a lower sliding cylinder 3 and an upper connecting cylinder 7. The lower sliding cylinder 3 is set to be a sleeve, which slides on the middle and lower non-smooth columns of the central axis 2. The upper connecting cylinder 7 is set to be a sleeve, which is threadedly connected to the middle and upper threaded shaft of the central axis 2, and is rotated to adjust the height as needed. The present application also includes an internal connector 4, an external connector 6, a fixed sleeve 8, a support rod 11, and a jack 12;
[0032] An inner connecting piece 4 is connected to the outer side of the lower slide 3.
[0033] A fixing sleeve 8 is connected to the upper connecting tube 7.
[0034] External connecting parts 6 are connected to the upper and lower surfaces of the template 5.
[0035] A support rod 11 is set between the outer connecting part 6 and the inner connecting part 4 at the lower part of the template 5, a support rod 11 is set between the outer connecting part 6 and the fixed sleeve 8 at the lower upper part of the template 5, and a jack 12 is set between the upper connecting tube 7 and the lower sliding tube 3.
[0036] In this way, the device is connected by first installing the outer connecting piece 6 on the lower upper part of the template 5, then connecting the inner connecting piece 4 on the outer side of the lower slide tube 3, and connecting the fixing sleeve 8 on the upper connecting tube 7, and then using the support rod 11 to connect the template 5 with the central axis 2 and the parts thereon to form an umbrella shape. During use, the upper and lower ends of the template 5 are supported, and the force generated by the support is all concentrated on the central axis 2 and transmitted in opposite directions, so that the entire support structure is in an integrated balanced rotation state and the support stability is high. Moreover, during the use of the device, the support rod 11 is connected by plugging, and then the jack 12 is used to level the entire template 5 so that it is in a vertical state. After the construction is completed, the jack 12 is reset to loosen the bottom support rod 11, thereby dismantling it. The entire structure is easy to disassemble, and each component can be recycled.
[0037] In one embodiment, to facilitate connection and disconnection, the outer connector 6 and the inner connector 4 are configured with the same structure, including a shaft seat and a sleeve. The sleeve is connected to the sleeve via a shaft, and the support rod 11 is inserted into the two sleeves. In this way, when in use, the outer connector 6 is inserted and then tightened by the jack 12. When disassembling, the jack 12 is released and the support rod 11 is pulled out, making disassembly convenient.
[0038] In one embodiment, to facilitate disassembly and adjustment to different diameters, a threaded shaft 9 is internally threadedly connected to the fixed sleeve 8, with a hexagonal nut fixed to the threaded shaft 9. A horizontal connecting tube 10 is fixed to one end of the threaded shaft 9, and a support rod 11 is inserted into the sleeve of the horizontal connecting tube 10 and the external connecting member 6. In this way, the threaded shaft 9 and the fixed sleeve 8 form a telescopic shaft, which can be adjusted as needed, facilitating both installation and disassembly and adjusting supports of different diameters.
[0039] In one embodiment, in order to achieve force balance, the center line of the sleeve of the outer connecting member 6 on the upper part of the template 5 and the center line of the horizontal connecting tube 10 are located on the same horizontal plane.
[0040] In one embodiment, in order to facilitate disassembly, the sleeve center line of the outer connecting member 6 at the lower part of the template 5 is lower than the sleeve center line of the inner connecting member 4.
[0041] In one embodiment, for the sake of relative stability, three jacks 12 are provided.
[0042] Finally, it should be noted that, in this document, relationships such as first and second, etc., are used solely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
