Description
Technical Field
The utility model relates to a construction machinery technical field, concretely relates to take grout sleeve of location buckle.
Background
In the existing connection method of the prefabricated reinforced concrete members, grouting sleeve connection is a common mode.
The existing grouting sleeve mostly adopts a cast iron sleeve and a seamless steel pipe sleeve. The production process of the cast iron sleeve is easy to cause the problems of cracking and the like of a product, and the cast iron piece has poor ductility and high brittleness, and is easy to crack or damage in the transportation and construction processes, so that the connection quality of the sleeve is influenced. The die sinking cost of the cast iron sleeve is relatively high, the production process is relatively complex, and the problems can be solved by adopting the seamless steel tube sleeve to replace the cast iron sleeve.
The seamless steel pipe is used as a grouting sleeve, and the steel bar is difficult to position in the component prefabrication process, the steel bar needs to be placed into the prefabrication end of the sleeve firstly in the component prefabrication process, and concrete is poured after sealing, so that on one hand, the steel bar is easy to slide in the sleeve when a steel bar cage is fixed, the contact area of the steel bar and grouting material is reduced, and the connection strength is reduced; on the other hand, if the radial positioning of the steel bars in the sleeve deviates, the grouting material in the sleeve is unevenly distributed, and the connection strength of the sleeve is reduced.
The utility model discloses a utility model with application number CN202121971001.2 discloses a install reinforcing bar positioner's full grout sleeve, including sleeve, positioner, sealing plug, thick liquids business turn over hole.

However, when the steel bar is inserted in place, the problem of radial positioning of the steel bar in the seamless steel tube sleeve can be solved by the positioning device, the axial positioning is realized by the connection between the sealing ring and the sleeve, and the axial positioning effect cannot be guaranteed because: during the casting process, under the action of the slurry and the vibration of the sleeve, the sealing ring may move relative to the sleeve, and the steel bar itself may also move relative to the sealing ring along the axial direction, and at this time, the sealing ring has no enough constraint force on the steel bar. Therefore, the axial positioning of the steel bars in the sleeve is not really solved, and once the steel bars slide axially, the radial positioning effect is lost, so that a large unsafe factor exists in the use process. In addition, the positioning device of the document can only radially position the reinforcing steel bars on one side, and an additional positioning device is required to be installed when the reinforcing steel bars on the other side are positioned, so that the device is complex in structure and inconvenient to use.
