Description

Technical Field

[0001] The invention relates to the technical field of curtain wall construction, in particular to an adjustable cutting device and a method for building curtain wall construction. Background Art

[0002] The curtain wall is the outer wall of a building. It does not bear weight and is hung like a curtain, so it is also called a "curtain wall". It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It is composed of panels and a supporting structure system. It can have a certain displacement ability relative to the main structure or a certain deformation ability itself. It is an external protective structure or decorative structure of a building that does not bear the effects of the main structure. During the construction of the curtain wall, it needs to be cut according to the needs. At present, manual handheld circular saws are mostly used for cutting, but the workers' technical requirements are high and it is easy to cause uneven cutting positions. Therefore, auxiliary fixed cutting devices have appeared, which use slide rails to move the cutting tools for cutting. For example, the Chinese invention patent with authorization announcement number CN115959822A discloses a curtain wall cutting device for building curtain wall construction, including a fixed frame; a movable component on the fixed frame; the movable component includes a fixed plate slidably connected to the fixed frame; a vertical through groove on the fixed plate and a horizontal through groove communicating with the vertical through groove; a second fixed plate slidably connected to the fixed frame is passed through the horizontal through groove; However, the current cutting device has the following defects: When cutting curtain walls, there is often a need for oblique cutting, such as at corners. However, current cutting devices cannot accurately adjust the angle, making it difficult to complete such cutting requirements. After the curtain wall is cut, the cut position is prone to deformation or burrs, requiring additional grinding, which is more troublesome.

[0003] To this end, we propose an adjustable cutting device and method for building curtain wall construction to solve the above problems. Summary of the Invention

When the present invention is used, a cutting reference line is drawn on the curtain wall according to the cutting requirements; according to the size of the curtain wall, the positions of the rear baffle 46 and the side baffle 49 are adjusted, the curtain wall is placed on the top surface of the first support plate 413 and the two third support plates 420, and pushed until the curtain wall is against the rear baffle (46), and then the front baffle 43 is rotated to a vertical position, and the first electric push rod 414 and the second electric push rod 419 are pressed down to press the surfaces of both ends of the curtain wall; the angle of the rotating arm 24 is adjusted by the pneumatic push rod 214 so that its angle is consistent with the cutting reference line, and then the transverse rod 22 drives the cutting structure 3 to the starting position of the cutting reference line; the hydraulic cylinder 323 drives the shell cover 31 to move downward until the roller 322 contacts the curtain wall surface, and then the drive motor 314 is started, and the cutting structure 3 is moved along the guide rod 25 The curtain wall is cut in a straight line position by cutting the circular saw 32. During cutting, the upper grinding disc 36 and the lower grinding disc 38 contact the cutting position of the curtain wall panel for grinding until the cutting structure 3 leaves the end point of the cutting reference line, and the cutting work of the curtain wall panel is completed. The present invention carries the cutting structure 3 through the guide rod 25, and the rotating arm 24 can change the angle together with the guide rod 25, so that the angle can be adjusted according to the cutting requirements. In this way, when cutting, the cutting structure 3 moves along the path of the guide rod 25, and can complete cutting work at different angles, and can meet the needs of oblique cutting. When cutting, the upper grinding disc 36 contacts the surface of the curtain wall cutting position for grinding, and the lower grinding disc 38 contacts the surface of the curtain wall cutting position for grinding under the action of the spring 311. After the cutting is completed, the cutting position is also polished at the same time. There is no need to set up a separate polishing process, which is more convenient and more efficient.
