Fabricated building grouting teaching and practical training device

Abstract

The invention discloses a fabricated building grouting teaching practical training device, which comprises a wall body composed of a low-density wall and a high-density wall, a steel bar framework isarranged in the wall body, the low-density wall is made of foamed concrete, the high-density wall is made of concrete, a grouting cavity is formed in the high-density wall, and a grouting sleeve is arranged in the grouting cavity. A grouting pipe and a grout overflowing pipe are connected to the grouting sleeve, and one end of the grouting pipe and one end of the grout overflowing pipe extend outwards to penetrate out of the wall body; a pressure sensor is arranged in the grouting cavity, and a cable is connected to the pressure sensor; a rotary spray head is arranged in the grouting cavity and is connected with a water pipe; a water outlet is formed in the high-density wall and located in the bottom of the grouting cavity, and a plug is arranged at the position of the water outlet. The device has the advantages of being small in simulation error, small in potential safety hazard, capable of being used for repeated grouting, low in maintenance frequency and capable of better meeting the cultivation requirement for the grouting skill in the cultivation activity of assembly type building industry workers.

Description

Technical field[0001]The invention belongs to the field of prefabricated building grouting devices, and particularly relates to a prefabricated building grouting teaching and training device.Background technique[0002]Prefabricated buildings have been developed in my country for nearly 30 years. In recent years, under the strong support of the country, they have achieved considerable development. The prefabricated components of the prefabricated building are processed in the prefabricated component production plant. The prefabricated components are made of concrete. After curing to the design strength, they are transported to the installation site for hoisting. After the hoisting is completed, the prefabricated components need to be grouted to ensure that each piece is prefabricated The component is integrated with the adjacent prefabricated component in the vertical direction. The most common method of grouting treatment is to carry out sleeve grouting connection processing, that is...

Problems solved by technology

The patent publication No. CN209297537U discloses a prefabricated shear wall grouting teaching and training device for prefabricated building shear walls, which is composed of transparent plates as a frame to simulate prefabricated shear wall grouting, which is convenient for students to observe the walking track of the grouting material and deeply understand the principle of grouting. However, The roughness of the transparent plate is very different from that of the prefabricated components made of concrete, and the simulation error is relatively large. Moreover, there is no steel skeleton inside, which also leads to a large simulation error, which leads to the training device being ineffective in teaching and training. lacking

Although the shear wall on the construction site can also be used for grouting training, the prefabricated components must first be hoisted into a shear wall before the grouting training. Due to the bulkiness of the prefabricated components, there is a risk of falling during hoisting and grouting training. The potential safety hazard is relatively large, and it cannot be cleaned after grouting, and only one grouting can be performed, which cannot meet the requirements of repeated operations for grouting teaching and training
