Problems solved by technology

In the current grouting device for the prefabricated and assembled substructure of elevated columns, the "point brake" grouting method is mostly used for pumping grouting, that is, related operations are performed manually, it is difficult to accurately control the amount of grouting, and problems such as insufficient grouting are prone to occur, and the integral grouting process The air bubbles in the middle may not be completely released, causing local stress concentration, making it difficult to guarantee the engineering quality and economic performance of the elevated column
Due to the extensive use of human resources in the construction process, the efficiency of the filling process is extremely low and the construction time is increased

Abstract

A segmented elevated column grouting device, including: a grouting mechanism mounted on a moving mechanism; the moving mechanism includes: a screw frame, a vertical moving component and a horizontal moving component, the screw frame is surrounded and arranged on the periphery of the column, and the vertical moving component and The horizontal moving components are all arranged on the screw frame to form a whole; the grouting mechanism includes: a grouting machine, a feeding pipe, a grouting gun and a control component connected in sequence, wherein: the grouting machine is connected with the mortar storage tank, and the control component is connected with the grouting gun Connect to control the grout gun to realize the grouting process. The invention realizes fully automatic grouting, saves labor costs and reduces the probability of safety accidents, improves construction efficiency, and reduces project cost; during the grouting process, it can effectively control the amount of grouting material and grouting time, and avoid engineering failures caused by insufficient watering. Quality problems, realize automatic and accurate grouting.

Description

technical field [0001] The invention relates to a technique in the field of building construction, in particular to a segmented elevated column grouting device. Background technique [0002] In order to improve the quality of mechanized construction and speed up the construction speed of elevated columns, automation technology has developed rapidly in the application of prefabricated and assembled elevated columns. In the current grouting device for the prefabricated and assembled substructure of elevated columns, the "point brake" grouting method is mostly used for pumping grouting, that is, related operations are performed manually, it is difficult to accurately control the amount of grouting, and problems such as insufficient grouting are prone to occur, and the integral grouting process The air bubbles in the middle may not be completely released, causing local stress concentration, making it difficult to guarantee the engineering quality and economic performance of the ...
