Portable cement paste injection pressure gun

Abstract

The invention relates to equipment used in the field of building construction, in particular to a portable cement paste injection pressure gun. The portable cement paste injection pressure gun comprises a gun cap, a paste storage barrel, a piston, a jacking rod, a dredge needle, a gun handle, a trigger, a boosting plate, a fixing plate and a spring, wherein a paste outlet nozzle communicated with the inner side of the gun cap is arranged at the front end of the gun cap, the gun cap is connected with the paste storage barrel, the piston is arranged at the inner side of the paste storage barrel, the jacking rod sequentially penetrates through the fixing plate, the boosting plate and a through hole in the rear end wall of the paste storage barrel from front to back and then is fixedly connected with the piston, the piston can move front and back in the paste storage barrel under the pushing and pull action of the jacking rod, the rear end of the dredge needle sequentially penetrates through the piston and a dredge needle penetrating hole in the rear end wall of the paste storage barrel and then is fixedly connected with the boosting plate, the front end of the dredge needle extends into the paste outlet nozzle and can come into and out of the paste outlet nozzle freely, and the dredge needle can make reciprocating motion front and back relative to the paste outlet nozzle under the action of the boosting plate. The portable cement paste injection pressure gun can be used for construction of hollow joint or hole paste injection construction conveniently, is uniform in outlet paste, enables paste injection to be in place, and can effectively guarantee the paste injection construction quality.

Description

technical field [0001] The invention relates to equipment used in the field of building construction, in particular to a cement slurry pouring pressure gun. Background technique [0002] In building construction, due to technical requirements, some parts of masonry or concrete structures need to reserve gaps or holes, or due to construction quality problems, there are gaps or holes, and grout needs to be poured into these parts. The traditional process adopts manual pouring, and the cement slurry often only stays on the surface of the void or hole, and it is difficult to fill it inside, which affects the quality of grouting. Since the positions of the voids or holes are relatively scattered and the space is small, it is not suitable to use a large pressure grouting machine for grouting based on the consideration of convenient construction and cost control. Therefore urgently need a kind of portable device that can go deep into void or hole grouting, to satisfy the grouting ...
