Description

Exterior finishing panel for easy silicon caulking operation

The present invention relates to an exterior wall finishing panel, and more particularly, to an exterior wall finishing panel capable of neatly and easily working with silicone caulking at a joint between the exterior wall finishing panels arranged and fixed in a grid shape to be spaced apart from each other. .

In general, among the exterior wall finishing methods of buildings, the dry method is a method of attaching and fixing the finishing panel to the exterior wall of the building by interposing a separate fixing device made of metal between the building and the finishing panel, and largely employs an open joint structure. The construction is divided into a method to achieve a structure and a method to form a closed joint structure, and the construction time is short, the convenience of work, and the advantages of construction are high, so it is a widely used construction method.

In the conventional dry method using a metal frame as a basic frame, the metal frame is placed horizontally and vertically on the wall in consideration of the designed pattern, and it is installed by welding or bolt assembly, and an insulation material is inserted and installed between the frames by a grid method. In the case of fixing and attaching the factory-made finishing panel to each joint with screws or dedicated brackets, and caulking the joints with silicone or exposing the joints without caulking, The installation work is carried out after waterproofing using a thin metal plate or a waterproof cloth between the finishing panels.

In the case of a conventional closed joint structure, caulking between the finishing panels, that is, the joint area, is performed using silicone, but the working process is cumbersome, and unless you are an experienced worker, the caulked silicone surface is not neatly processed, so it looks messy. As a result, there is a problem in that the working time is increased due to the addition of refining the caulked silicon surface.

In addition, a lot of defects may occur during the caulking construction process, and accordingly, the cost may increase.If a defect occurs, the original function of the caulking is lost, and excellent and foreign substances penetrate through the joint, resulting in a decrease in waterproofness and airtightness. There is a problem that it can be.
