Description

Basic prefab panel unit integrated thin bricks into base sheet, manufactured by combining thin bricks with binding grooves on the back to the locking protrusions of the base sheet with embossed rim protruding strips. and supporting frame wall finishing method using of the same}

The present invention relates to a unit prefab unit panel installed to decorate the exterior wall of a building with a certain area in consideration of securing seismic performance and transport and installation, which is partially constructed in a factory or on site in a dry type. After being integrated and manufactured in a certain unit size, it can be constructed as a unit module without masonry and jointing processes on site, and the thin brick is locked with a binding structure between the binding groove and the locking jaw on the base sheet, and the integrated behavior is secured. The present invention relates to a prefabricated unit panel and a base frame outer wall finishing method using the same to safely endure the load without dropping.

Due to the aging of the population, a labor shortage is appearing in the labor market, and it is analyzed that the labor shortage will begin to appear in earnest from 2030. (2017.08.10., JoongAng Ilbo) In addition, due to the lack of skilled workers such as professional masonry building personnel, on-site labor costs are constantly rising. In the case of the Gyeongju Earthquake (2016) and Pohang Earthquake (2017) in Korea, major damage cases occurred in non-structural elements such as exterior materials such as curtain walls and glass, damaged and dropped, ceiling materials damaged and dropped, masonry non-structural walls, and stucco wall cracks and collapses. However, this is larger than the damage caused by structural element damage.

In the event of an earthquake, non-structural elements are linked to secondary and tertiary damage due to the loss of function of the building due to the damage of facilities and important equipment, as well as direct or indirect personal and indirect damage to personnel and property by falling and overturning roads. Therefore, safety against earthquakes must be secured. In the Korean Building Structural Standard (KBC 2016), a seismic design clause for architectural and mechanical non-structural elements was added, but it is difficult to secure structural safety as a test method to verify the seismic details and performance of non-structural elements is not provided. There is this.

Meanwhile, as the demand in the construction market for clay bricks made of soil is increasing recently, they are being converted into functional products with various designs and functions. In addition, with the growth of the remodeling construction market, the clay brick market is expected to increase in demand for functional products such as antibacterial, flame retardant, and earthquake resistance, as well as products of various designs.

According to Article 32 of the Enforcement Decree of the Domestic Building Act, the subject of seismic design mandatory has been expanded to all houses, two stories or more than 200㎡, and major facilities such as hospitals, schools, and child/elderly welfare facilities are obligated to design seismic resistance regardless of area. Seismic design standards for non-structural materials such as In accordance with the'Energy Saving Design Standards for Buildings' revised in September 2018, not only the heat transmission rate and thickness standards of the insulation materials used in buildings, but also the grade standards for the latest KS insulation materials were additionally reflected, so that the insulation standards of the building became the level of the passive building. The standards for energy efficiency of buildings are being strengthened, such as improvement and application.

The size of a typical clay brick is 190mm(L)×90mm(D)×57mm(H), and the eccentricity increases due to the increase in the finishing distance due to the reinforcement of external insulation regulations, which can cause structural problems. Due to the shortage of professional masonry personnel and the increase in labor costs, construction methods that can be produced and installed in dry units are being developed, and product development that can satisfy reinforced insulation regulations and seismic regulations is needed.

As a background technology of the present invention, as Korean Patent Application Publication No. 10-2010-0003760, a'building decoration panel' has been proposed. This is to adhere and fix a plurality of ornaments in a masonry form for each panel that is attached to the wall of the building vertically and horizontally, but by connecting these ornaments and the panel with a separate fixing member, the ornaments were not separated from the panel. However, the background technology requires a long working process in which a fixing member is inserted one by one at the rear of the panel to install the ornaments one by one. At this time, since the fixing member and the ornament are only bonded by an adhesive, there is a disadvantage in that the ornament may be removed due to an earthquake load when a poor adhesion occurs. In addition, there is a problem of additional joint work after joining the ornament.

Another technology that serves as the background of the present invention is Korean Patent Registration No. 10-1763540, which proposes a'modular insulation assembly using a sandwich panel'. This is a pre-casting method that allows easy wall finishing work on the site by attaching tile bricks to the sandwich panel in advance and making it in a module form. However, in the background technology, since the tile brick is bonded to the fitting protrusion through an adhesive member, there is a fear that the tile brick may be separated from the fitting protrusion when an earthquake load occurs when a poor adhesion occurs. In addition, there remains the same problem of additional joint work after joining the tile bricks.
