The present invention relates to a pipe duct cover panel assembly of a building structure, and more particularly, an improved building structure to improve assembly precision, productivity, economy, and quality through a dry machining process that excludes a painting process and a welding process of pipe duct cover panel assembly.

In general, a pipe duct constructed in a state embedded in a wall to form a tubular conduit through which each layer communicates up and down is installed in a multi-story building structure such as an apartment or a mixed-use building. In the pipe duct of such a building structure, a standing pipe such as a pipe group for building equipment such as a water supply pipe, a drainage pipe, a sewage pipe, and a fire extinguishing pipe is accommodated so that the branch pipe piped to each floor is connected.

In a pipe duct constructed in a typical large complex building structure, a fire hose or a fire extinguisher is provided, a fire hydrant box, a water pump box, a waterproof appliance box, and a power distribution box are accommodated and covered with the wall of the building structure at the front opening and concealed. The cover panel assemblies are installed side by side, and the door panel installed in the cover panel assembly to be opened and closed is opened to enable operation, use, inspection, and maintenance activities from the outside.

On the other hand, the conventional conventional pipe duct cover panel assembly is a panel frame manufactured in the form of a rectangular frame by combining a vertical frame member and a horizontal frame member that are processed and molded by cutting and bending a metal plate, which is a raw material, to a certain design standard and dimensions. The door panels are combined in an openable and openable state to form a modular assembly structure. The pipe duct cover panel assembly manufactured as described above is constructed so as to fit the front of the frame in the form of a door frame installed at the entrance of the pipe duct during the interior construction of the building structure.

However, in the case of the conventional pipe duct cover panel assembly as described above, referring to the manufacturing process diagram schematically illustrated in FIG. 1 , a vertical frame member by processing a metal plate, which is a raw material, by cutting and bending based on design criteria. and horizontal frame member and opening/closing door are respectively molded (S-11), and the vertical frame member, horizontal frame member, and opening/closing door, which have been molded and processed, respectively, are given aesthetics and corrosion resistance to harmonize with the color of the wall of the building structure. For example, a protective film is formed on the surface through a coating process such as powder coating or anti-rust coating (S-12). In this way, the vertical frame member and the horizontal frame member having a protective film formed on the surface by the painting process are coupled to face each other to form an integral structure by a welding process (S-13). At this time, bolts, nuts, or screws are additionally fastened to areas where welding is difficult. Accordingly, a panel frame in the form of a rectangular frame is manufactured (S-14), and an openable and openable door panel is coupled to one side of the panel frame (S-15), thereby producing a modular assembly structure (S-16).

Therefore, the conventional pipe duct cover panel assembly has disadvantages and problems in that productivity is significantly reduced due to preparation and post-treatment processes in the painting process prior to the assembly process.

In addition, in the conventional conventional pipe duct cover panel assembly, as the vertical frame member and the horizontal frame member that have undergone the painting process are joined by a welding process to assemble in a rectangular frame shape, local distortion deformation or cracking of the welded portion due to welding heat Alternatively, there is a problem in that quality defects such as breakage and peeling of the coating film occur.

In addition, as the conventional pipe duct cover panel assembly is assembled using separate fastening members such as bolts and nuts or screws to secure and maintain assembly precision in areas where it is difficult to join by welding, assembly precision and productivity are reduced. It has disadvantages and problems that not only decrease, but also increase the manufacturing cost due to an increase in the number of parts required for assembly.

The present invention has been derived under the technical background as described above, and the problems of the above-mentioned background technology are the contents that the present applicant possessed for the derivation of the present invention or learned during the derivation of the present invention, and must be applied to the present invention It cannot be said that it was previously announced to the general public.
