Problems solved by technology

The current general practice is to select the vent hole at the bottom of a certain grouting sleeve as the grouting hole, and use a grouting gun or a grouting pump to complete the grouting. This method has certain disadvantages: (1) Since the grouting process is a pressurized operation, after the grouting nozzle is removed , it will inevitably cause the liquid level in the sleeve to drop, resulting in the grouting at the top of the sleeve is not dense; (2) due to the evaporation or loss of water in the grouting material, it may cause the liquid level in the grouting sleeve to drop, but it cannot be found in time, resulting in the top of the sleeve Grouting is not dense

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] see first Figure 1~3 As shown, the grouting connection structure of the prefabricated component of the present invention is mainly composed of a grouting sleeve 11 buried at the bottom of the prefabricated component 20 for inserting butt steel bars, and an observation tube 12 buried at the bottom of the prefabricated component 20 .

[0030] Cooperate Figure 4 with Figure 5 As shown, the grouting sleeve 11 in this embodiment adopts a half-grouting sleeve, which is also applicable to other grouting sleeves such as a full-grouting sleeve. Inserted, the inside of the grouting sleeve 11 forms a grouting space, the lower part of the wall of the grouting sleeve 11 is provided with a grouting port 111, the upper part of the wall of the grouting sleeve 11 is provided with a grouting port 112, and the grouting port 111 and the grout...

Abstract

The invention discloses a grouting connecting structure of a prefabricated part and a construction method thereof. The grouting connecting structure comprises grouting sleeves and an observation pipe, wherein the grouting sleeves are arranged at the bottom of the prefabricated part in an embedded mode and serve for insertion of butt-joint reinforcing steel bars, a grouting port is formed in the lower portion of the sleeve wall of each grouting sleeve, a grout discharge port is formed in the upper portion of the sleeve wall of each grouting sleeve, and grouting holes and grout discharge holes corresponding to the grouting ports and the grout discharge ports are formed in the prefabricated part; the observation pipe is arranged at the bottom of the prefabricated part in an embedded mode, a pipe port at a first end of the observation pipe is formed in the end face of the bottom of the prefabricated part, a pipe port at a second end of the observation pipe is formed in the surface of the side wall of the prefabricated part, and the arrangement location of the pipe port located at the second end of the observation pipe is higher than the top positions of the grouting sleeves. According to the grouting connecting structure of the prefabricated part and the construction method thereof, by pre-embedding the observation pipe at the lower end of the prefabricated part, the grouting sleeves and the observation pipe are filled with grout, by means of the intrinsic pressure of the filling grout, automatic grout replenishment is completed when the liquid level at the tops of the grouting sleeves declines, and the observation pipe is utilized for raising the grout liquid level, so that it is convenient for workers to make observation, the grout is replenished in time, and the grout compactness is guaranteed.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a grouting connection structure of prefabricated components and a construction method thereof. Background technique [0002] The prefabricated shear walls connected by grouting sleeves need to connect the vertical reinforcement by grouting the grouting sleeves. The current general practice is to select the vent hole at the bottom of a certain grouting sleeve as the grouting hole, and use a grouting gun or a grouting pump to complete the grouting. This method has certain disadvantages: (1) Since the grouting process is a pressurized operation, after the grouting nozzle is removed , it will inevitably cause the liquid level in the sleeve to drop, resulting in the grouting at the top of the sleeve is not dense; (2) due to the evaporation or loss of water in the grouting material, it may cause the liquid level in the grouting sleeve to drop, but it cannot be found in...
