Description

Non-combustible exterior panel for exterior wall finishing and its construction method {NONCOMBUSTIBLE EXTERIOR PANEL FOR EXTERIOR WALL FINISH AND METHOD OF CONSTRUCTION THEREOF}

The present invention relates to a non-flammable exterior panel for exterior wall finishing and a method of construction thereof. More specifically, the construction of the material and installation structure of the exterior wall finishing panel installed on the exterior wall of a building is differentiated from the conventional one, so that it is easy to construct in the field. It relates to a panel having operational safety and a construction method thereof.

In general, various types of exterior wall finishing panels are installed on the exterior wall of a building for the purpose of decoration, insulation, and sound absorption.

The exterior wall finishing panel is widely used because it can effectively apply various textures, gloss, and various functions for each material compared to conventional tile or painting construction, and it is easy to construct with an insulation material.

Panels for exterior wall finishing are made of various materials having characteristics such as durability, light weight, heat insulation, workability, and sound insulation. For example, lightweight concrete panels mainly used in large and high-rise buildings are formed by laminating a foamed polyethylene core between two layers of cement boards, and have excellent flexural strength, high water resistance, and high insulation efficiency. Aluminum panels are formed by laminating foamed polyethylene with a core material between thin aluminum plates, and have excellent smoothness peculiar to metal materials and have excellent workability because they have lighter weight and flexible workability compared to other materials of the same thickness.

Looking at a general construction method of a panel for exterior wall finishing, an insulating material is attached to the wall of a building, and a truss made of a section steel is mounted as an anchor on the wall with a grid. The upper, lower, left and right sides of the panel are fixed by bolting or welding to the truss, and then the gaps between the panels are caulked with silicone to finish.

As an example of a technology related to a conventionally known exterior wall finishing panel, in Korea Patent Registration No. 10-0191887, a metal frame body composed of a plurality of section steels and each section steel is welded or bolted together to be assembled in a grid shape, and the outdoor side It constitutes an outer wall panel including a metal plate to be attached, a frame made of steel materials of several H-shaped sections attached to the outside side of the metal plate at intervals in the height direction, and an exterior panel attached to the outside side of the frame frame.

As another example, in Korean Patent Registration No. 10-1077662, a vertical frame and a horizontal frame are joined by a welding part, a plurality of panels are coupled to the outside of the vertical frame and the horizontal frame, and the plurality of panels are bolts and rivets by brackets. In this way, it forms a spaced groove formed at regular intervals on the outside of the vertical and horizontal frames and is firmly coupled, and the spaced groove constitutes an outer wall panel that is filled so that silicon can be in close contact with the vertical and horizontal frames.

As another example, Korean Patent Registration No. 10-0547435 discloses an exterior panel for construction that is molded of metal and mounted on a frame formed on the exterior surface of a building, and a frame mounted on the exterior panel and mounted on the exterior surface of the wall. The bracket is composed of a U-shaped part, a mounting part extending from one end of the U-shaped part, and a support part protruding at right angles to the mounting part in the direction of the other end of the U-shaped part, and formed on the outer surface of the wall through the mounting part. Construct an exterior panel for building that is made to be mounted on the frame.

The present invention provides a non-combustible exterior panel mounting a panel portion, a heat insulating core, and a series of structures for installation of the panel.

Therefore, compared to the prior art, there is an advantage of remarkably improving workability and ensuring safe construction by excluding construction processes such as installing a truss at the site.

In particular, the present invention can solve the problem of frequent fire accidents during operation by applying a non-combustible material to the panel portion and the insulation core and excluding welding work during panel construction as in the prior art.

In addition, the present invention is equipped with a double-blocking configuration between panels, so that separate silicone caulking work can be excluded from the outside as in the prior art, so that the appearance of the panel can be variously implemented, and various types such as improving productivity through work efficiency.

Consisting of having a third coupling portion 195 extending from the support body 191 to contact the wall fixing means 150 and forming a third fastening hole 194 to fasten the piece to the wall fixing means 150 Non-combustible exterior panel for exterior wall finishing, characterized in that. A first step of inserting and attaching the insulating core 120 to the core fixing pin 111 formed on the inner side of the panel unit 110 and bending and fixing the ends of the core fixing pin 111;
A second process of coupling the panel coupling bar 130 to four upper, lower, left, and right portions on the inner side of the panel unit 110;
A third step of interposing one side of the second blocking means 170 in the second coupling groove 134 of each panel coupling bar 130;
A fourth step of interposing one side of the first blocking means 140 in the first coupling groove 133 of the upper or lower panel coupling bar 130 and the left or right panel coupling bar 130;
A fifth step of coupling the other side of the second blocking means 170 through the third coupling groove 161 of the panel support bar 160;
A sixth step of disposing the L-shaped wall fixing means 150 on the wall of the building at intervals capable of accommodating the upper, lower, left, and right sides of the panel that has passed through the fifth step, and installed as an anchor 151;
A seventh step of mounting the third coupling portion 195 of the panel mounting bar 190 on the mounting of the wall fixing means 150 and driving and fixing the piece;
The panel that has undergone the fifth process is placed on one side of the panel installation bar 190, and the second of the panel installation bar 190 is placed in the fourth coupling groove 162 and the fifth coupling groove 163 of the panel support bar 160. An eighth step of mounting the coupling part 193 to drive the piece to install the non-combustible exterior panel construction method for exterior wall finishing, comprising: a.
