Abstract
Description
Technical Field
[0001] The utility model relates to a concrete pouring device, in particular to an end pipe structure for concrete pouring in municipal engineering. Background Art
[0002] During the municipal construction process, in some places, a concrete pump truck is needed to transport concrete. When the end of the pump pipe of the concrete pump truck is at a relatively high distance from the pouring site, a hose needs to be installed at the end of the pump pipe to prevent the concrete from falling from a high place and causing segregation.
[0003] In the prior art, when directly pouring concrete by using this end hose method, segregation still occurs if the height is relatively high. Content of the Utility Model
[0004] The main purpose of the utility model is to provide an end pipe structure for concrete pouring in municipal engineering to avoid segregation during the concrete pouring process.
[0005] To achieve the above purpose, the utility model provides an end pipe structure for concrete pouring in municipal engineering, including:
[0006] A plurality of conical pipes connected end to end in series, and the conical pipes are made of rubber;
[0007] An anti-segregation device, which is hung outside the conical pipe located above. The anti-segregation device includes a plurality of parallelly arranged rings, and these rings are connected by the first steel bars. A plurality of second steel bars are evenly distributed on each ring. The head ends of the second steel bars are fixedly connected to the rings, and the tail ends of the second steel bars incline downward and cross the central axis of the rings. The tail ends of these second steel bars are at different heights and are not connected to each other.
[0008] Preferably, the whole anti-segregation device is conical, and the diameters of these rings decrease successively from top to bottom.
[0009] Further preferably, the outer diameter of the lowermost ring of the anti-segregation device is equal to the inner diameter of the end of the conical pipe.
[0010] Preferably, the projections of the second steel bars on adjacent rings on the horizontal plane do not overlap.
[0011] Further preferably, the uppermost ring does not abut against the inner wall of the conical pipe.
[0012] Preferably, the outer wall of the lower part of the conical pipe is provided with ears, and a hanging part is provided above the conical pipe. The hanging part of the lower conical pipe can be hung on the ears of the upper conical pipe.
[0013] Further preferably, the segregation prevention device further includes a hook. One end of the hook is fixedly connected to the uppermost ring, and the other end of the hook is hung on the ear part of the upper conical pipe.
[0014] Even more preferably, the hook is an L-shaped plate. The short end of the hook is fixedly connected to the ring, and an opening is provided at the other end of the hook. The hook is hung on the ear part through the opening.
[0015] The beneficial effects of the present utility model are as follows:
[0016] The present utility model designs the hose into a multi-section series-connected conical pipe, and then arranges a segregation prevention device in each conical pipe, thereby preventing the separation of aggregate and mortar in the concrete. In addition, the present utility model uses a ring as the skeleton for the segregation prevention device, which can effectively prevent the phenomenon of blockage in the hose when the particle size of the aggregate in the concrete is relatively large.

[0024] The following clearly and completely describes the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0025] As Figure 1 and Figure 2As shown in the figure, a terminal pipeline structure for concrete pouring in municipal engineering includes a plurality of conical pipelines 1 and a plurality of segregation prevention devices 200. Among them, the heads and tails of these conical pipelines 1 are connected in series with each other. At the same time, the large-mouth ends of the conical pipelines 1 face upward, and a segregation prevention device 200 is arranged in each conical pipeline 1. Preferably, the conical pipeline 1 is made of rubber.
[0026] Specifically, in this embodiment, the segregation prevention device 200 is integrally conical. The segregation prevention device 200 is hung outside the conical pipeline 1 located above. The segregation prevention device 200 includes a plurality of rings 221 arranged in parallel with each other. These rings 221 are connected by the first steel bars 222. A plurality of second steel bars 223 are evenly distributed on each ring 221. Preferably, three second steel bars 223 are arranged in this embodiment. The number of the second steel bars 223 is not set too much to avoid blocking the conical pipeline 1. The head ends of the second steel bars 223 are fixedly connected to the rings 221. The tail ends of the second steel bars 223 incline downward and cross the central axis of the rings 221. The tail ends of these second steel bars 223 on the same ring 221 are at different heights and are not connected to each other. In this way, the aggregate and mortar can also flow between these second steel bars 223.
[0027] As described above, since the segregation prevention device 200 is integrally conical, the diameters of these rings 221 gradually decrease from top to bottom.
[0028] In this embodiment, the outer diameter of the lowermost ring 221 of the segregation prevention device 200 is equal to the inner diameter of the end of the conical pipeline 1. The ring 221 located below is used to support the lower outlet of the conical pipeline 1.
[0029] In this embodiment, the arrangement of the second steel bars 223 on adjacent rings 221 is arranged indirectly. In this way, the second steel bars 223 on adjacent rings 221 will both stir the concrete. Therefore, the projections of the second steel bars 223 on adjacent rings 221 on the horizontal plane do not overlap.
[0030] In this embodiment, the ring 221 provided with the second steel bars 223 is not in contact with the inner wall of the conical pipeline 1. This enables the ring 221 itself to also play a stirring role.
[0031] In this embodiment, as Figure 1 shown, an ear part 110 is provided on the outer wall below the conical pipeline 1, and a hanging part 120 is provided above the conical pipeline 1. The hanging part 120 of the conical pipeline 1 located below can be hung on the ear part 110 of the conical pipeline 1 located above.
[0032] The segregation prevention device 200 further includes a hook 210. One end of the hook 210 is fixedly connected to the uppermost ring, and the other end of the hook 210 is hung on the ear 110 of the upper conical pipe 1. Specifically, the hook 210 is an L-shaped plate. The short end of the hook 210 is fixedly connected to the ring 221, and an opening is provided at the other end of the hook 210. The hook 210 is hung on the ear 110 through the opening. That is to say, when two adjacent groups of conical pipes 1 are installed, most of the long plate of the L-shaped plate is located within the overlapping part of the two conical pipes 1.
[0033] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
