Description

FIELD OF THE INVENTION [0001] The present invention relates to a method of constructing an exterior panel of an atypical building using a metal plate of a furniture structure,

The present invention relates to a method of constructing a curved exterior panel of an amorphous building using a structural metal plate having a post-and-lintel construction (PLC), wherein the main structural part is an amorphous steel structure, In order to solve the problems of complex and inaccurate design and construction management, a structural metal plate of a furniture structure and a curved exterior panel having a plurality of reinforcing bars on the metal plate are processed in an irregular steel structure, And a method of assembling a structure and a panel by using a ball-bracket by lifting the steel structure over a steel structure.

Recently, as the demand for the atypical architecture has increased, the demand for more beautiful and beautiful appearance of the building has been increasing.

Atypical architecture refers to the construction of irregular curved surfaces with double curvature, which reflects various forms of design.

Such a structure needs to be designed and manufactured by a complicated design because the whole or part of the exterior has a curved shape that is inclined, narrowed, or twisted away from the square or rectangle as in the conventional case.

Atypical architecture was introduced in the 2000s, and the development of computer-based engineering technology such as BIM (Building Information Modeling) enabled the design and construction.

The BIM application of the atypical building has the advantage that the information data of each stage can be integrated and managed based on the 3D object information based on the 3D.

Therefore, efficient construction of irregular structures minimizes the inconsistency and errors of drawings caused by uncertainty of design and construction information and incorrect expression, minimizes repetitive work, increase of rework cost, extension of air, and deterioration of quality.

Because of this, it is possible to apply the atypical architecture in the field in Korea, and the application is gradually spreading.

However, the design of the atypical architecture is a method of obtaining a curved line by calculation on a straight line connecting certain points having two curvature curves and obtaining a three-dimensional curved surface by extending the curved line, that is, And it should be divided into the form and size that can be constructed by expressing it as a two - dimensional drawing again.

In addition, the divided panel requires an optimization process that minimizes the curvature of curvature in various directions because the processing process is complicated when the curvature of the atypical curved surface is larger.

The optimization of the panel has the problem that the designer must consider various factors such as the geometric intent of the structure, the degree of deformability of the building shape, the material properties of the material, constraints on the fabrication and construction, geometrical panel knowledge, and cost.

In addition, due to the irregular shape, it is difficult to secure the joint performance of the building due to the non-standardized architectural elements and members, and it is difficult to secure the structural safety of the building such as airtightness, watertightness, insulation, wind pressure and thermal performance and efficient arrangement of the exterior material.

Also, when a plurality of panels corresponding to the width of the panel are installed by installing rods at the time of installing the external panel, if the strength of the structure is lower than the allowable strength calculation formula, There is a method of reinforcing the structural strength by installing bars and fixing them with brackets or brackets.

However, this method greatly increases the load on the external surface construction equipment of the building, which increases the material cost and the construction period, which increases the construction cost.

Also, since the curved surface panel may be curved continuously due to tensile force unlike the flat panel, a sub-frame should be additionally installed in the middle part of the panel. Fixing the inside of the panel to the main frame at the edge of the panel will lessen the risk of deformation, but the shape of the outward facing surface requires additional work.

In particular, since a complex two-way curved surface is manually manufactured by using a bending machine, it is difficult to model each time a coordinate is input, when the shape of a shape changes slightly in the same pattern.

In this way, the following problems are listed when applying the present technology.

Therefore, in order to solve such a problem, there is a need for a construction method for facilitating the joining of the sub-structure and the external panel applied to the main structure as a method for simplifying the field work of the atypical building Do.

However, in the atypical building, the X, Y, It is impossible to control the position points of many panels by the construction method of the orthopedic building. Therefore, there is a need for a method of integrating the metal structure of the atypical building with the external panel and the structure in accordance with the exact coordinates. The present invention relates to a method for safely and accurately constructing an irregular sub-frame and an exterior panel on a steel structure so that an exterior panel of an irregularly curved surface structure conforms to a real-time three-dimensional design.

In the method of constructing the exterior panel of the atypical building using the metal plate of the post-and-lintel construction according to the present invention, the basic structure of the exterior panel is such that the upper end of the structural steel plate of the T type intersects with the other structural steel plate One member is fixed to the side of the longitudinal direction and the other member is fixed to the side of the lateral direction so as to intersect with each other so as to be fixed in a furniture-like structure. In this frame, a plurality of frame- And has a curved surface shape.

In the present invention, the combination of the main frame and the external panel composed of reinforcement bars is combined with a ball-bracet, which can be adjusted in direction and rotation, Exterior panel with frame and reinforcement bar and factory finishing material, bringing the finished product to the factory, producing the finished product by field measurement and modeling, cutting the product, welding, processing, coating and packing, It is preferable to stably and precisely install the modular panel assembled with the main frame and the reinforcing bar by fixing it with a bracket to adjust the angle of the bar.

It is possible to form a curved panel and simplify the construction of the outer panel which is complicated when the outer panel is coupled with the main steel member by the application of the present invention.

Since the main frame is manufactured using T-Bar and a plurality of reinforcing bar sub-frames are combined on the main frame to form an external panel, safety and maintenance of various types of curved surfaces are ensured. Manageability is ensured.

It is easy to assemble the brackets between the curved panel and the frame, and the followability and bonding performance according to the behavior and displacement of the building after installation.

The frame of Post and Lintel Construction is made by using T-Bar and it is easy to form the curved panel by combining multiple reinforcing bars in this frame, and the free angle adjustment of the bracket And it is unnecessary to adjust the construction error by combining with the book.

The brackets are conveniently fixed between the mainframe and the panel, so they are not affected by external forces.

It is possible to assemble and fasten the panel in exact position and direction by using bracket after assembling the module frame on the ground by using the furniture type T-bar and connecting it to the sub base of the structure.

The external panel and the fixed bracket can be adjusted by the fixed angle of the panel in correspondence with the free curved surface instead of the grid shape to solve the deviation and precise construction, thus ensuring watertight performance even under static and dynamic pressure.
