Description

Prefabricated wall disjunctor grout sleeve Technical Field The utility model belongs to the technical field of assembled building, concretely relates to prefabricated wall disjunctor grout sleeve. Background In the current prefabricated wall construction, grouting sleeve construction can only finish one sleeve grouting operation at a time, and a grouting opening and a grouting outlet are required to be plugged respectively. The untimely plugging can easily cause the loss of grouting in the grouting sleeve, so that the grouting in the sleeve is not full, and the connection quality of the components (steel bars) is affected. Patent document with application number of CN202211181154.6 discloses a grouting construction device for connecting a prefabricated upright post with a grouting sleeve and a construction method thereof. Through establishing ties grout sleeve group and grout subassembly to carry out sealed setting to grout sleeve interface department of establishing ties, then adopt grout subassembly to circulate the grout sleeve, grout closely knit in the grout sleeve, thereby realize the connection between the reinforcing bar in the prefabricated stand. Compared with the traditional grouting sleeve grouting method, the series grouting is carried out on a plurality of grouting sleeves, so that repeated grouting times can be simplified, the problems of leakage grouting and the like caused by poor management in the grouting process are avoided, the grouting efficiency is improved, and the grouting time is shortened. However, the prior art including this document still has the following technical problems: (1) The grouting pipe and the grouting pipe of the grouting sleeve face the same direction, so that the connecting pipeline for series connection of the grouting sleeve is required to be positioned on the outer side of the component, and as shown in fig. 2 of the document, the grouting sleeve still has to seal a plurality of reserved grouting openings and grouting outlets on the surface of the component after grouting is finished. (2) Since the grouting pipe and the grout outlet pipe of the grouting sleeve face the same direction, the method of the patent document cannot be directly used inside the member because the connecting pipe occupies the thickness space of the prefabricated member greatly, and if the prefabricated member has the condition of connecting a plurality of rows of reinforcing steel bars, the thick space inside the member cannot accommodate a plurality of rows of grouting sleeves connected in series in this way. (3) Grouting sleeve's slip casting pipe and play thick liquid pipe are the level setting, lead to the slip casting after accomplishing at shutoff slip casting pipe and play thick liquid pipe time leak thick liquid, lead to the unable filling of grouting sleeve, and then lead to the thick liquid compactness in the sleeve not enough, influence the connection quality of reinforcing bar. Disclosure of utility model The utility model discloses a prefabricated wall disjunctor grout sleeve, the utility model discloses a system improvement to sleeve self structure and connecting piece structure has obtained a disjunctor grout sleeve that is applied to in the prefabricated wall, and this disjunctor grout sleeve can be according to the prefabricated shaping of mill of prefabricated wall's size, improves the telescopic installation effectiveness of grout by a wide margin, and then, this novel disposable slip casting operation that can realize a row of grout sleeve in the wall guarantees that thick liquid can not run off in the sleeve and keep full state, changes into front need not to reserve slip casting mouth and play thick liquid mouth from originally carrying out every preformed hole shutoff in prefabricated wall front, so avoided follow-up to the prefabricated wall openly a plurality of slip casting mouths and play thick liquid mouth carry out the complex process of shutoff one by one, also further improved the structural strength of prefabricated wall simultaneously. In order to achieve the above purpose, the technical scheme of the utility model is: The utility model provides a prefabricated wall disjunctor grout sleeve, includes sleeve body, Z shape connecting pipe, the sleeve body have a plurality of, one side lower part of every sleeve body all is equipped with the slip casting coupling, the sleeve body outer wall upper portion of slip casting coupling contralateral is equipped with out the slip casting coupling, through Z shape connecting pipe intercommunication between the slip casting coupling of adjacent sleeve body and the slip casting coupling, a plurality of sleeve bodies connect gradually into one row overall structure through Z shape connecting pipe. Preferably, the included angle between the axis of the grouting pipe joint and the axis of the grouting pipe joint is 180 degrees. Preferably, top and bottom of sleeve body among the overall structure of a row flush, the slip
