Description

The present invention relates to a glass facade construction method using rib glass when constructing a glass facade by attaching face glass to rib glass.

A structure using glass as a building outer wall is known (see, for example, Patent Document 1). Patent Document 1 shows a so-called SSG construction method, in which the face glass that is the outer wall is attached to the mullion that is the building frame.

On the other hand, some mullets are made of glass. At this time, the glass that supports the face glass is called rib glass. When rib glass is used, it is often applied to a relatively conspicuous position (such as an entrance) of a building, and the combination of face glass and rib glass is also called a glass facade. Therefore, the method of constructing this glass facade is called a glass facade construction method (sometimes called a rib glass construction method).

When constructing such a glass facade, a rib glass is arranged between two adjacent face glasses, and the rib glass is bonded to each face glass with a sealing material made of a silicone-based adhesive material.

JP 2018-25019 A

However, since the rib glass must be adhered to two adjacent face glasses, the adhesion work at the construction site is time-consuming and troublesome. In particular, on-site bonding work is required to be performed as little as possible from the viewpoint of accuracy and quality control.

Furthermore, the demand for wind pressure resistance is increasing in recent years, and the range of sealing materials used for face glass is also increasing. In that case, it is necessary to increase the thickness of the rib glass, and it is necessary to secure the thickness by using expensive thick glass or by using laminated glass or the like for the rib glass. This leads to an increase in the weight of the rib glass, leading to a decrease in workability and an increase in cost.

The present invention takes the above-mentioned conventional technology into consideration, and can provide peace of mind from the aspects of accuracy and quality control, and can cope with the thin rib glass even if the width of the sealing material is increased in order to increase the resistance to wind pressure. It is an object of the present invention to provide a glass facade construction method using rib glass that can be

In order to achieve the above object, in the present invention, a face glass forming a wall surface of a building, a joint material arranged between the adjacent face glasses, and a first a metallic connecting hardware formed by fitting the plate and the second plate together; a sealing material for adhering the connecting hardware to the adjacent face glass; and an interior side of the connecting hardware A glass facade construction method using rib glass for constructing a glass facade comprising rib glass arranged in a vertical direction to the face glass and a sealing base material for bonding the rib glass and the connecting hardware in a preparation step of forming a rib glass unit by attaching the first plate to the side surface of the rib glass via the seal base material at a location different from the construction site; and fitting the face glass to the first plate and attaching the face glass to the rib glass unit via the second plate and the sealing material. Provide construction methods.

Preferably, it further has a seal width defined as the width of the seal materials adhered to the adjacent face glasses, and the width of the seal base material is shorter than the seal width.

Preferably, the connecting hardware is capable of swinging vertically and horizontally by following the swinging of the sealing member.

Preferably, the preparing step further includes attaching the second plate to the face glass via the sealing material.

According to the present invention, since the seal base material can be attached to the side surface of the rib glass in a preparation process at a place other than the construction site, for example, at a place such as a factory where manufacturing facilities are in place, the worker can seal the rib glass at the site. Compared to mounting the base material, it can be constructed with peace of mind in terms of mounting accuracy and quality control. In particular, the adhesive strength can be appropriately quality-controlled, and the reliability thereof can be enhanced. In addition, since the seal base material is attached to the rib glass in advance in this way, it is possible to reduce the number of work processes on site, and to perform quick construction.

Further, since the width of the seal base material is shorter than the width of the seal, the thickness of the rib glass can be kept thin even if the width of the seal material is increased in order to improve the resistance to wind pressure.

In addition, since the connecting hardware can swing vertically and horizontally, even if the face glass shakes vertically and horizontally due to an earthquake or wind pressure and this is transmitted, the connecting hardware absorbs this movement, so the rib glass is affected. never.

In addition, if the second plate is attached to the face glass via a sealing material in the preparation process, the on-site work can be further reduced, providing highly reliable work in terms of quality. can do.

BRIEF DESCRIPTION OF THE DRAWINGS It is a schematic perspective view of the glass facade which should be constructed by the glass facade construction method using the rib glass which concerns on this invention. It is a flowchart of the glass facade construction method using the rib glass which concerns on this invention. 1 is a schematic sectional view showing an example of a glass facade that can be obtained by applying the present invention; FIG. Fig. 3 is a schematic cross-sectional view showing another example of a glass facade that can be obtained by applying the present invention;

First, with reference to FIGS. 1 and 2, the structure of a glass facade 1 to be constructed by the glass facade construction method using rib glass according to the present invention will be described. The glass facade 1 is used for the outer wall of a building, etc., and constitutes the wall surface thereof. A face glass 2 composed of a plurality of glass plates is arranged side by side as a wall surface. A joint material 3 made of an adhesive sealing material is arranged between the face glasses 2 . A metallic connecting hardware 4 is arranged on the interior side of the joint material 3, that is, on the interior side of the face glass 2. - 特許庁The connecting hardware is adhered to the left and right sides via the face glass 2 and the sealing material 5, respectively. That is, each of the adjacent face glasses 2 and one connecting hardware 4 are bonded with the sealing material 5 . The connecting hardware 4 is formed by fitting a first plate 9 and a second plate 10 together. The first plate 9 and the second plate 10 are made of metal plates.

A plate-shaped rib glass 6 arranged in a direction perpendicular to the face glass 2 is arranged on the indoor side of the connecting hardware 4 . In the illustrated example, the rib glass 6 is formed of a laminated glass in which two glass plates are stuck together with an intermediate layer. However, the rib glass 6 is not limited to such a laminated glass, and may be a single plate glass, a multi-layer glass, or a laminated glass in which three or more glass plates are bonded together. The rib glass 6 is adhered to the connecting hardware 4 by the seal base material 7 . Therefore, the face glass 2 is supported by the rib glass 6 via the sealing material 5 , the connecting hardware 4 and the sealing base material 7 .

When constructing the glass façade 1 having the structure described above on site, the construction method is the following glass façade construction method using rib glass according to the present invention. As shown in FIG. 3, first, a preparatory step is performed (step S1). In this preparatory step, the rib glass unit 15 is formed by attaching the first plate 9 to the side surface of the rib glass 6 via the seal base material 7 at a location other than the construction site. The construction site is a place where the glass facade 1 is constructed, and is a place where construction is performed (for example, outdoors). Since the seal base material 7 and the first plate 9 are attached to the side surface of the rib glass 6 at a place other than this place, for example, a place such as a factory where the indoor manufacturing equipment is installed, the worker must install the seal base material at the site. Compared to installing 7, it can be constructed as a safe thing from the aspect of the accuracy of the installation accuracy and the aspect of quality control. In particular, the adhesive strength can be appropriately quality-controlled, and the reliability thereof can be enhanced. In addition, since the seal base material 7 is attached to the rib glass 6 in advance in this way, it is possible to reduce the number of work steps at the site, and to perform the construction quickly. Although the seal base material 7 is an adhesive, it is made of a relatively hard material because its adhesive strength is such that it receives wind pressure.

The rib glass unit 15 formed in this manner is brought into the site and undergoes the site process (step S2). That is, in the present invention, the rib glass 6 to which the first plate 9 is attached via the seal base material 7 in the preparatory step is transported to the site. In this on-site process, the face glass 2 is attached to the rib glass unit 15 at the construction site. Although any order may be applied at the site, for example, the second plate 10 is attached to the first plate 9 first, and then the face glass is adhered via the sealing material 5 . After that, a joint material 3 is used to line up the face glass 2 to complete the glass facade 1. - 特許庁

It should be noted that the second plate may be further attached to the face glass 2 via the sealing material 5 in the preparatory step. In this way, if the second plate is attached to the face glass 2 via the sealing material 5 in the preparation process, the on-site work can be further reduced, and the quality can be improved. Can provide high quality work.

At this time, assuming that the seal width defined as the width of the seal members 5 bonded to the adjacent face glasses 2 is A, the width B of the seal base material 7 is shorter than the seal width A. In recent years, wind pressure resistance performance is required, and in order to withstand this wind pressure, it is necessary to increase the seal width A. In order to increase the seal width A, the width of the joint material 3 is mainly lengthened. The rib glass 6 also needs to have a width (having the same length as the seal width A) matching this. However, since the connecting hardware 4 is interposed between the sealing material 5 and the rib glass 6 in the glass facade 1, the width B of the sealing base material 7 adhered to the connecting hardware 4 can be made shorter than the seal width A. can. The fact that the width B of the seal base material 7 can be reduced means that the thickness of the rib glass 6 can also be reduced. can be kept thin. Since the rib glass 6 can be thinned, the color of the glass itself is also lightened, so that the design is improved.

In addition, the connecting hardware 4 can swing in the vertical and horizontal directions by following the swinging motion of the sealing material 5 . As described above, the connecting hardware 4 is formed of the first plate 9 and the second plate 10, and these slide together to absorb the shaking in the vertical and horizontal directions. That is, since the connecting hardware 4 can swing in the vertical and horizontal directions, even if the face glass 2 shakes in the vertical and horizontal directions due to an earthquake or wind pressure and this is transmitted to the connecting hardware 4, the connecting hardware 4 absorbs this movement. Therefore, the rib glass 6 is not affected and cracked. In the example of FIG. 1, a second plate 10 having a substantially C-shaped cross section sandwiches a first plate 9 made of two plate members fixed to each other with bolts 8 from the left and right. Since there is a gap between the first plate 9 and the second plate 10, it is possible to swing (sway) by moving between the gaps in the horizontal direction. In addition, since it is possible to move in the vertical direction (vertical direction) by simply sliding each other, it is also possible to swing (lock) in the vertical direction. In particular, the glass façade 1 using the rib glass 6 often uses the vertically long rib glass 6, so it is advantageous to be able to absorb vibrations in the vertical direction.

If the glass facade construction method using rib glass according to the present invention is used, a glass facade as shown in FIG. 4 can also be constructed. In this example, a metal piece 11 extends outward from the connecting hardware 4, and the metal piece 11 has a plate-shaped protection portion 12 extending in the left-right direction. Since the protective portion 12 covers the joint portion of the face glass 2, the metal piece 11 functions as a sash. If this structure is used, the joint material 3 becomes unnecessary, and the protection part 12 receives the wind. In the case of such a structure, a sealing material 13 is arranged between the face glass 2 and the protective portion 12 . This sealing member 13 is a so-called weather seal for maintaining watertightness, and is made of a relatively soft material. As a manufacturing method, first, the second plate 10 is fitted into the rib glass unit 15, and the metal piece 11 on which the face glass 2 is arranged is pushed into the second plate 10 and fitted. Then, the sealing materials 5 and 13 are arranged. In addition, in the example of FIG. 4, what applied the double glazing as the face glass 2 is shown. The presence of the protective portion 12 serving as a sash improves the durability of the double glazing against internal condensation. In particular, a warranty period of about 10 years can be obtained. Other configurations, actions, and effects are the same as in the example of FIG.

Further, by using the glass facade construction method using rib glass according to the present invention, it is possible to construct a glass facade as shown in FIG. In this example, double glazing is used as the face glass 2, but wired glass is used as the inner glass. As a result, it is possible to play a role as fire prevention equipment, and it is possible to exhibit fire resistance performance for 20 minutes. It can also be applied to areas where there is a risk of inflammation. Further, in this example, the first plate 9 is in the shape of a rectangular cylinder, and is covered with the second plate 10 having a C-shaped cross section. More specifically, the metal piece 11 covers the connecting hardware 4 consisting of the first plate 9 and the second plate 10 . The first plate 9, the second plate 10, and the metal piece 11 are fixed with screws 14. Since the screw holes are larger than the diameter of the screws 14, the face glass 2 swings and this Even if the vibration is transmitted to the connecting hardware 4 via the metal piece 11, the vibration is not transmitted to the rib glass 6 because the screw 14 swings in the screw hole and absorbs the vibration. The manufacturing method is the same as in the example of FIG.

Further, by using the glass facade construction method using rib glass according to the present invention, it is possible to construct a glass facade as shown in FIG. In this example, double glazing is used as the face glass 2, but wired glass is used as the inner glass. As a result, it is possible to play a role as fire prevention equipment, and it is possible to exhibit fire resistance performance for 20 minutes. It can also be applied to places where there is a risk of fire spreading . Further, in this example, the first plate 9 is in the shape of a rectangular cylinder, and is covered with the second plate 10 having a C-shaped cross section. More specifically, the metal piece 11 covers the connecting hardware 4 consisting of the first plate 9 and the second plate 10 . The first plate 9, the second plate 10, and the metal piece 11 are fixed with screws 14. Since the screw holes are larger than the diameter of the screws 14, the face glass 2 swings and this Even if the vibration is transmitted to the connecting hardware 4 via the metal piece 11, the vibration is not transmitted to the rib glass 6 because the screw 14 swings in the screw hole and absorbs the vibration. The manufacturing method is the same as in the example of FIG.
