Embodiment Construction
[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It should be noted that the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict, and the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0031] like Figure 1-Figure 6 As shown in the figure, a grouting sleeve with an imitation intestinal wall device is attached, which includes a grouting sleeve linear cylinder 1 and an imitation intestinal wall inner cylinder 2. The upper and lower parts of the grouting sleeve linear cylinder 1 The sides are respectively provided with a slurry outlet 11 and a slurry inlet 12, and a section of a simulated intestinal wall inner tube 2 and two sections of a simulated intestinal wall inner tube 2 are r...

The invention provides a grouting sleeve internally attached with an intestinal wall simulating device, and belongs to the field of prefabricated concrete members. The problems that grouting materials in an existing grouting sleeve are prone to backflow, grouting is not full, and the connection strength is affected are solved. The grouting sleeve comprises a grouting sleeve linear cylinder body and intestinal-wall-imitating inner cylinders, a slurry outlet and a slurry inlet are formed in the side faces of the upper portion and the lower portion of the grouting sleeve linear cylinder body respectively, and the intestinal-wall-imitating inner cylinders are arranged at the positions, away from the upper end and the lower end of the grouting sleeve linear cylinder body by a certain distance, of the grouting sleeve linear cylinder body respectively. The two sections of intestinal wall-imitating inner cylinders are coaxially arranged with the grouting sleeve linear cylinder body, each intestinal wall-imitating inner cylinder comprises multiple sections of intestinal wall-imitating inner cylinder wall sections and multiple sections of intestinal wall-imitating inner ribs which are integrally arranged, and the multiple sections of intestinal wall-imitating inner cylinder wall sections and the multiple sections of intestinal wall-imitating inner ribs are arranged in a crossed mode; all the intestinal-wall-imitating inner cylinder wall sections are attached to and fixedly connected with the inner wall of the linear cylinder body of the grouting sleeve, and all the intestinal-wall-imitating inner ribs are obliquely arranged in the direction of the grout outlet. Slurry backflow is effectively prevented.
Description
technical field [0001] The invention belongs to the technical field of prefabricated concrete components, in particular to a grouting sleeve with an imitating intestinal wall device attached therein. Background technique [0002] With the rapid development of my country's economy and urbanization, the prefabricated building model has been rapidly promoted and used in China in recent years. The use of grouting sleeves to connect steel bars is currently the most common connection method between prefabricated components and has been widely used. [0003] The grouting fullness of the connection sleeve directly determines the connection strength of the steel bar, which in turn affects the structural strength of the entire building. However, at present, due to the quality of the grouting material does not meet the standard requirements, the steel bar cannot enter the sleeve due to the installation deviation and is cut off or the anchoring strength is insufficient, the slurry outl...
