Fabricated building grouting teaching practical training equipment cleaning method and device

Abstract

The invention discloses a cleaning method and device for prefabricated building grouting teaching and practical training equipment, and the method comprises the steps: arranging a plurality of rotating nozzles (5) in a cavity (24) of the teaching and practical training equipment, jetting water flow which rotates in the circumferential direction through the rotating nozzles (5), enabling slurry on the same height region in the cavity (24) to be impacted by the water flow, and enabling the slurry to flow into the cavity (24); and then all the slurry in the cavity (24) is impacted by water flow in a manner of lifting and rotating the spray head (5) in a reciprocating manner. The cleaning device has the advantages that the teaching and practical training equipment can be cleaned, the service life of the teaching and practical training equipment is prolonged, and the fault rate is low.

Description

technical field [0001] The invention belongs to the field of prefabricated building grouting teaching and training equipment, and in particular relates to a grouting cleaning method and device for prefabricated building teaching and training equipment. Background technique [0002] A large number of prefabricated components are used in prefabricated buildings. The components have steel skeletons inside. The walls are formed by assembling the components. The components are often grouted after the assembly is completed. The grouting will fill the cavity inside the components and make the wall. The upper and lower adjacent members are firmly bonded together. In order to make the overall structural strength and mechanical performance of the wall good, the grouting material is required to be poured in place, and no air bubbles should remain after grouting, which puts forward high requirements for the technical level of the grouting personnel. Before starting the job, pre-job tra...

Problems solved by technology

Since the rotating nozzle is fixed in the cavity, the sprayed water can only be sprayed to the top of the cavity first, forming the effect of rain, washing away the slurry adhered to the inner wall of the cavity and the steel skeleton, due to the effect of rain The coverage of the cavity is limited, resulting in a part of the slurry remaining in the cavity, and the cleaning is not clean. After many times of teaching and training, the slurry remaining in the cavity coagulates into blocks, and after the slurry is refilled, the flow of the slurry is hindered. , the simulation effect is reduced, the students cannot have a deep understanding of the flow characteristics of the slurry, and the transparency of the teaching and training equipment is reduced, it is difficult to observe the flow state of the slurry, the effect of the teaching and training is reduced, and the teaching and training equipment cannot be used again , can only be scrapped, and the service life is low

However, the production cost of teaching and training equipment is high, and scrapping causes waste of resources, and the volume is large, which is difficult to dispose of after scrapping. It needs to be broken and transported to a distant landfill for landfill, and the scrapping cost is high.

[0004] Therefore, the existing rotary nozzle is used for cleaning teaching and training equipment, and there is a defect that the cleaning is not clean, resulting in a low service life of teaching and training equipment
