Roof positioning and line drawing device for construction site and roof positioning and line drawing method

Abstract

The invention discloses a top plate locating line-drawing device and method for a construction site. The top plate locating line-drawing device for the construction site includes a leg supporting rod,a line-drawing rod, a right angle dividing ruler and sliding blocks on the leg supporting rod, the line-drawing rod and the right angle dividing ruler; a leg supporting tine is arranged at one end ofthe leg supporting rod and a leg supporting rod scale is arranged on the leg supporting rod; one end of the line-drawing rod is hinged to the leg supporting rod and a clamping groove is formed in theother end of the line-drawing rod; the line-drawing rod is an adjustable telescopic rod and the bottom side of the right angle dividing ruler is fixed to the sliding block of the leg supporting rod;a dividing ruler of the right angle dividing ruler is vertical to the leg supporting rod and penetrates through the sliding block of the right angle dividing ruler; and the sliding block of the rightangle dividing ruler is hinged to the sliding block of the line-drawing rod. The top plate locating line-drawing device and top plate locating line-drawing method for the construction site has the beneficial effects that the top plate locating line-drawing device for the construction site is simple in structure, top plate locating line-drawing can be quickly carried out in the condition of takinga laser demarcation device for auxiliary means in a short time and little harm to eyes and working high above the ground is not needed, and labor is saved and potential safety hazard does not exist.

Description

technical field [0001] The invention relates to the technical field of building construction auxiliary devices, in particular to a roof positioning and line drawing device and a roof positioning and line drawing method for a construction site. Background technique [0002] Before the roof support and hanger is installed, it is necessary to position and draw lines on the fixed point of the support and hanger, that is, the position of the installation bolt. The conventional method is to first spring the line on the roof, and then the construction personnel need to use a steel tape to measure the distance on the spring line on the scaffold. Measure and position and draw lines. This method requires personnel to measure and draw lines, stabilize and move scaffolding, which consumes a lot of labor and involves high-altitude operations, and there are certain safety hazards; the laser line of the laser line thrower is bright and clear, and can quickly locate the target , but because...

[0002] Before the roof support and hanger is installed, it is necessary to position and draw lines on the fixed point of the support and hanger, that is, the position of the installation bolt.

Measure and position and draw lines. This method requires personnel to measure and draw lines, stabilize and move scaffolding, which consumes a lot of labor and involves high-altitude operations, and there are certain safety hazards; the laser line of the laser line thrower is bright and clear, and can quickly locate the target , but because the laser is irritating to the eyes, it is not suitable for long-term work, let alone high-altitude work
