Prefabricated building grouting device

Abstract

The invention relates to the technical field of building construction, in particular to a prefabricated assembly type building grouting device. The device comprises a grouting barrel, a piston rod is slidably inserted into one end of the grouting barrel, a grout outlet pipe penetrates through the other end of the grouting barrel, a leaking stoppage device is arranged at the top of the grouting barrel, and an adjusting device is arranged on the side, close to the piston rod, of the leaking stoppage device. During grouting, only one operator is needed to hold the grouting barrel by hand, concrete slurry is injected into the grouting hole in the bottom through the first sealing pipe, when the concrete slurry flows out through the second sealing pipe, grouting is stopped, the grouting barrel is pumped away, at the moment, the first sealing pipe is sealed by a first sealing plate under the action of a first spring, and the grouting barrel is sealed by a second sealing plate under the action of a second spring; and a second sealing plate is matched with a third sealing plate under the action of a magnetic pull rod to close a second sealing pipe, so that the concrete slurry can be prevented from flowing out of the grouting hole in the top in time, and the sufficient concrete slurry in the grouting hole is ensured.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a prefabricated building grouting device. Background technique [0002] Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, and the construction components and accessories such as floor slabs, wall panels, stairs, balconies, etc. are processed and manufactured in the factory, and then transported to the construction site. The connection method is assembled and installed on site. Therefore, such building components or accessories will have connection holes at the bottom during production, and two rows of grouting holes will be correspondingly opened on the sides of the components, and the upper and lower two The grouting holes are connected to each other. During assembly, the connecting holes at the bottom of the components are first inserted into the steel bars on the building f...

Problems solved by technology

[0003] However, due to the lack of automatic plugging device in the existing grouting cylinder, two people are required to cooperate with the operation to complete the entire grouting operation. In addition, in the process of removing the grouting cylinder from the grouting hole, part of the concrete slurry It will flow out from the grouting hole at the bottom, so when another worker responsible for plugging the hole operates slowly, a lot of concrete slurry will flow out of the grouting hole, which will affect the stability of the connection between the component and the floor
