Compass type control frame for marking ceiling rod guiding hole positions

Abstract

The invention discloses a compass type control frame for marking ceiling rod guiding hole positions. The inclined lower end of an inclined right rod can be embedded into a U-shaped fork at the inclined lower end of an inclined left rod, a first rod hole and a second rod hole are serially connected by the same pin rod after corresponding, the inclined left rod and the inclined right rod can rotateby taking the pin rod as a circle center, a screw is nailed in the middle of the side wall of the inclined left rod, a bolt is nailed in the middle of the side wall of the inclined right rod, a screwhole is drilled in the left end of a horizontal positioning plate and in sleeve connection with the screw, a horizontal rectangular through hole is integrally formed in the horizontal positioning plate, the horizontal positioning plate horizontally moves through the horizontal rectangular through hole by taking the bolt as a supporting point, the bolt can be screwed into a tightening nut, and thehorizontal positioning plate and the inclined right rod can be tightly connected after the tightening nut is tightened, so that the opening and closing angle between the inclined left rod and the inclined right rod is adjusted. The compass type control frame has the advantages of novel structure, simplicity and convenience in operation and strong practicability.

Description

technical field [0001] The invention belongs to the field of auxiliary equipment for building construction, and relates to a compass-type control frame used for marking the positions of guide holes of ceiling bud rods. Background technique [0002] The process of interior decoration of large buildings will involve the construction of concealed works, and the construction of concealed works will involve ceiling work, and the ceiling work needs to make holes and pre-plant sprouting rods on the top of each layer of roof first, because the ceiling The hole spacing between the buds needs to reach the standard of 900mm~1200mm, but at present, the hole spacing of the ceiling buds is mainly judged by the on-site visual inspection of the construction personnel. This construction method will have irregular construction, The problem of low work efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention provides a compass-type control f...
