Problems solved by technology

[0003] During the hoisting of various pipes and bridges during construction, the fixing of the hanging bars is generally carried out by first finding points on the ceiling with infrared rays, and then setting up movable scaffolding. Manual hand-held electric drill drilling, the disadvantage of this method is that it is inconvenient to operate when the infrared is set out to find points on the ceiling, and the speed and efficiency of scaffolding drilling are low.
According to statistics, two workers can only install 50 hanging bars per shift using this method of construction. This method of operation is difficult to operate, and the construction time is long and the construction cost is high.

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Depend on figure 1 , A ceiling drilling device of the present invention mainly consists of two parts, one part is a plug-in vertical rod, and the other is a movable curved rod connector. The pluggable pole is composed of two steel pipes, the upper steel pipe is 50MM in diameter and 2000MM in length, the lower steel pipe is 75MM in diameter and 2000MM in length, the lower end is designed with a triangular support and centerline pendant, and the upper steel pipe is inserted into the lower steel pipe. The movable curved rod connector consists of three 30*50 square tubes with a length of 600MM and one arc-shaped square tube with a length of 900MM. The ends of the square tubes are designed with round holes and connected by pins. Use outdoor money to project a straight line on the ground where you need to drill holes to install hang...

Abstract

The invention provides a hole drilling device for ceilings. The hole drilling device for the ceilings mainly comprises a drawable vertical rod and a movable bent rod connecting piece. In a construction process, inconvenience caused by construction of a scaffold is greatly reduced; the hole drilling device is convenient to operate, and can be constructed in narrow space; the construction progress is increased; and the labor cost is saved. When the hole drilling device is used, a location on the ground is found out by infrared rays; the hole drilling device is positioned by using a pendant below equipment, is quick and convenient to operate and is positioned accurately; and straightness of mounting components can be effectively guaranteed. The hole drilling device for the ceilings is easy to manufacture, and is quick and easy to construct; the engineering cost is reduced; and the popularization and application value is high.

Description

[0001] technical field [0002] The invention belongs to the technical field of construction engineering, in particular to a ceiling drilling device in the construction process. Background technique [0003] During the hoisting of various pipelines and bridges during engineering construction, the fixing of the hanging bars is generally done by first finding points on the ceiling with infrared rays, and then using manual hand-held electric drills to drill holes by setting up movable scaffolds. It is inconvenient to operate when setting out the line to find a point, and the construction speed and efficiency of setting up scaffolding to drill holes are low. According to statistics, two workers can only install 50 hanging bars in each shift of two workers in this way. This mode of operation is difficult to operate, the construction time is long, and the construction cost is high. Contents of the invention [0004] Aiming at the deficiencies in the existing technology, the tec...
