Description

[Detailed Description of the Invention] This invention relates to exterior replacement and installation of a curtain wall in which the constituent materials of the existing curtain wall are left in place without being removed, and the existing curtain wall is surrounded and covered with new materials. This paper relates to the disclosure of a method for replacing curtain walls using a method of covering the entire inside surface.

Therefore, when replacing the exterior of a curtain wall of this type in the past, it is natural to remove the existing curtain wall material and then replace the exterior of the building with new materials. This has become a common method.

However, in this method, the old material used as the existing curtain wall material is generally discarded, blocking the path to reuse, and also requiring a large amount of labor to dispose of it. .

The present invention was devised especially in view of the inconveniences in the conventional precedent, and utilizes the existing curtain wall material and uses it as an exterior core material to create strength and to use a new material. In addition to reliably preventing rust from forming or progressing in existing curtain wall materials, it also prevents aging of old panel materials and prevents peeling of old panel materials. It is designed to prevent this from happening.

In order to achieve appropriate and appropriate effects on these characteristics, the present invention aims to remove the existing curtain wall opening glass and replace the old curtain wall materials with mullions, blind materials, and exterior panels. The process of applying anti-corrosion treatment to metal forming materials including non-ferrous metals such as materials, rims and mounting brackets, and the method of applying anti-corrosion treatment to metal forming materials including non-ferrous metals such as rims and mounting brackets, and the method of applying rust prevention treatment to the upper and lower frames of curtain walls and blind materials in the former curtain wall materials. A step of attaching a new backing material that will serve as a base frame to the vertical wall, and attaching a new exterior decorative material and a membrane plate through the added backing material, and the step of attaching the removal opening glass. The steps of fitting and fixing this fitted glass with a new lumbering material, spreading and fixing a new exterior wall panel between the exterior decorative materials via a panel mounting backing material, and the above assembling are The process consists of applying caulking between new members, around the fitted glass, and between the new table board and the inner wall panel, and a detour means for this structure is also planned.

The details of the present invention will be described below with reference to a typical embodiment shown in the drawings. First, the existing curtain wall material, which is based on a cast concrete floor slab 1 and an inner wall panel 2, is fixed to the slab 1. The mullion 5 is supported by the fastener 3, which is an angle material, and the stiffener 4, which is an angle material fixed to the fastener 3. A blind member 7 is provided, and the exterior panel material 8 is supported on the blind member 7 and the mullions 5 through angle members.

The basic method of assembling a curtain wall is to attach a curtain box 9 to the material, especially to the side of the blind material 7 and the inner wall panel 2, and to attach the curtain box 9 to the side of the curtain box 9. At the same time, a ribbed edge 10 was attached to the mullion 5, a ribbed edge 11 was similarly attached to the blind timber 6.7, and the blind timber 7 and the wainscoting in the lower frame of the curtain wall were attached. The existing curtain wall is constructed by attaching a wainscot 12 between two inner wall panels.

For the existing curtain wall, first remove the window glass 13 at the opening of the existing curtain wall, then remove the zipper 3, stiffener 4, mullion 5, blind members 6, 7, exterior panel material 8, and ridges 10. Metal forming materials containing new non-ferrous metals are successively attached to the back stand 5, blind materials 6, 7, etc. which are coated with anti-rust coating.

First, backing materials 14a to 14e, which serve as the so-called base bones for attaching various new exterior design materials, are fixed to the mullion 5, and new In addition, in the upper frame of the curtain wall, a backing material 17 that serves as a base rib is attached to the blind material 7, and the exterior decorative material is attached through this backing material 17. The material 18 is fixed, and a backing material 19 is similarly attached to the blind material 7 at the lower frame of the curtain wall, and the exterior decorative material 20 is fixed via this attached backing material 19. Then, in the case of the blank material 6, a backing material 21.22 is attached to the blank material 6, and the exterior decorative material 23.
24 is fixed.

Next, the exterior decorative material 2 in the lower frame of the curtain wall
An angled wainscot mounting lining material 25 is attached to the inside surface of the curtain wall wainscot 0, and a similar lining material 26 is attached to the existing curtain wall wainscot 12, and a new wainscot board 27 is fixed via this lining material 25°26. be.

After fitting the window glass 13 to the new curtain wall structure, the fitted window glass 13 is fixed with a rim material, and then the panel is attached by attaching the backing material 28 to the exterior panel material 8 and the backing material. 14b, the new exterior wall panel 29 is supported by the backing material 28 and the exterior decorative material 18.

After installation, caulking material 30.3 is applied to the gaps between the parts and around the glass fittings.
1, and when installing the wainscoting board 27 and the interior wall panel 2 on the existing curtain wall, the gaps were similarly filled with caulking material 32 to complete all the covering steps.

In the present invention, as described above, the old members of the curtain wall are left as they are without being removed in any way, and the new members are covered with the old members as a core material. This eliminates the need for special measures for removing the opening member during construction, and significantly strengthens the construction strength of the curtain wall portion.

In other words, this construction method eliminates the need for much labor and equipment associated with removal work, and also avoids contamination on the surrounding construction surface.
It is designed to minimize obstruction to traffic around the surrounding area, and also to save resources by making use of old curtain wall materials that are normally disposed of.

In addition, this new method of installing curtain walls by covering the entire surface can prevent the formation or progression of rust in old curtain wall materials at a relatively low construction cost, as well as prevent aging of old panel materials. However, it was possible to prevent accidents such as peeling and falling of the panel material, and it was also possible to completely renew the exterior with an extremely simple installation method.Disclosure of a new extremely effective curtain wall installation method. It is related to.
