A vertical drilling device for the roof of a steel frame composite building

Abstract

The invention relates to a vertical drilling device for the roof of a steel skeleton composite building, which includes a driving motor, a fixed end, a drill bit, a fixing frame, a handle, a positioning support rod, a supporting spring, a vertical positioning mechanism and a sealing mechanism. A fixed terminal is installed at the end of the output shaft, and a drill bit is installed at one end of the fixed terminal. The housing of the driving motor is fixed with a fixed frame by bolts. Both ends of the fixed frame are symmetrically equipped with handles, and the upper end of the fixed frame is welded symmetrically. Positioning support rods, one end of the vertical positioning mechanism is connected with the positioning support rods, the outer walls of the two positioning support rods are sleeved with support springs, the inner wall of the vertical positioning mechanism is provided with a sealing mechanism, and the center of one end surface of the drive motor shell is provided with a The shaft hole, according to the invention, can meet the vertical drilling requirements of roofs with different angles, and is equipped with a sealing mechanism, which can effectively prevent waste chips from drilling from falling on the operator, and has higher practicability.

Description

technical field [0001] The invention relates to the technical field of drilling equipment, in particular to a vertical drilling device for the roof of a steel skeleton composite building. Background technique [0002] The steel frame composite building is a kind of building combined with steel frame, cold-drawn steel wire mesh and roof. A complete steel grid is conducive to confining concrete and improving the integrity of concrete components. Among them, the reinforcement mesh generally refers to the combination of planar reinforcement, such as the vertical and horizontal reinforcement in the floor; the reinforcement skeleton generally refers to the combination of three-dimensional reinforcement, such as the reinforcement in the beam and column. The steel frame is pre-lashed, and the top is laid on top of the steel frame. In the actual construction process, it is necessary to manually drill holes on the top through drilling equipment, and then install the fixing mechanism...

Problems solved by technology

[0003] However, a vertical drilling device for the roof of a steel frame composite building currently on the market has the following problems during use: a. Due to installation requirements, the position of the roof on the top of the steel frame is different, some are arranged parallel to the horizontal plane, and some are inclined It is arranged on the horizontal plane, and the traditional vertical drilling device for the roof of the steel frame composite building cannot effectively realize the positioning of the drilling when drilling the roof at the above position, that is, it cannot ensure that the drilling direction is perpendicular to the horizontal plane, resulting in Subsequent positioning and locking of the top plate cannot be performed normally; b. When drilling manually, since the drilling area on the top is located directly above the operator, in order to avoid the waste generated by the drilling from falling on the operator and causing harm, Especially for the eyes, it is necessary to arrange waste collection bags and other protective equipment at the drilling position before each drilling, but this type of protective equipment cannot be recycled, causing the operator to arrange it every time a hole is drilled, resulting in the entire The drilling process is cumbersome
