Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as Figure 1-6 As shown, the present invention provides a closed device for the slurry inlet of an assembled structural steel bar connection sleeve, including a seal 1, a hard tube 2, a sliding baffle 3 and a spring 4, the seal 1 is in the shape of a cone, and the center A through hole is opened; the hard tube 2 is cylindrical and is fixed in the through hole of the seal 1, the side close to the seal 1 with a large diameter is the front end, and the side close to the seal 1 with a small diameter One end is the rear end; the sliding baffle 3 is arranged on the front end of the hard pipe 2, and the diameter is smaller than the inner diameter of the hard pipe 2, so that the slurry can flow from the inner wall of the hard pipe 2 and the outer wall of the sliding baffle 3 One end of the spring 4 is connected with the sliding baffle 3 , and the o...

Abstract

The invention discloses a closing device for a grout inlet of a steel bar connecting sleeve for a fabricated structure. The closing device comprises a sealing part, a hard pipe, a sliding baffle and aspring, the sealing part is in a circular truncated cone shape, and a through hole is formed in the center of the sealing part; the hard pipe is cylindrical and is fixed into the through hole of thesealing part; the sliding baffle is arranged at the rear end of the hard pipe, and the diameter of the sliding baffle is less than the inner diameter of the hard pipe; and one end of the spring is connected with the sliding baffle, and the other end of the spring is connected with the front end of the hard pipe. After grouting, the grout inlet is automatically closed, and grouting material waste caused by human factors and potential safety hazards caused by the fact that the steel bar connecting sleeve is unsaturated due to grouting material backflow are reduced.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a closing device for a grout inlet of a prefabricated structural reinforcement connection sleeve. Background technique [0002] Because the prefabricated structure has the characteristics of low construction cost and easy construction, it is being promoted on a large scale in our country. Various building components including beams, columns, and walls can be prefabricated in the prefabrication yard, and their quality can be well guaranteed. The prefabricated components are mainly connected by steel connecting sleeves. In the process of on-site assembly, after the prefabricated components are installed at the predetermined positions and the joints are sealed, the steel bar connection sleeve needs to be grouted on site using a grouting machine. After each grouting is completed, the grouting machine needs to be pulled out and plugged into the plug. In this process, the grou...
