Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mounting structure for a window glass plate. (Conventional technology) Conventionally, when installing window glass in a concrete structure, it is common practice to first fix a metal sash to the opening, and then use the groove for fitting the face material of the sash to fit the metal sash to attach the glass plate. It has been adopted. In recent years, with the development of air-conditioning equipment and noise countermeasures, windows are gradually becoming closed.
Publication No. 15154 describes a method in which the structure itself is used as a window frame and the glass plate is attached via an elastic gap-filling ring made of synthetic rubber, etc., and a method in which metal sashes are not used even in the case of snap-in type window glass. As an example, Japanese Utility Model Publication No. 50-43293 discloses that the frame body is composed of an outer frame that is fixed to the window opening in advance, and an inner frame that sandwiches the plate glass through a glazing channel, and after the glass is sandwiched, the outer frame is fixed to the window opening. There are two known types: one that is attached to the Furthermore, Japanese Utility Model Publication No. 62-141889 discloses a method of fixing the glass plate without exposing the sash to the outside by bonding one side of the glass plate to a grooved sash with a widened end shape using a silicone resin adhesive. structure is disclosed. (Problems to be solved by the invention) In the above-mentioned conventional technology described in Japanese Patent Publication No. 47-15154, the edge of the window glass attachment part is made of concrete and has a finished surface of the engaging part such as a concave groove or a convex strip. However, the design was unsatisfactory, and depending on the top surface finish and dimensional accuracy, it did not adhere well to the fitting elastic gap ring, causing problems with watertight performance. In cases where the edge of the glass plate is swallowed by the metal sash, there may be a large temperature difference depending on the type of glass plate or where it is fitted, for example, when exposed to sunlight, there may be a temperature difference between the center and the periphery. This caused problems such as thermal cracking of the glass plate. The glass plate mounting structure disclosed in Japanese Utility Model Application No. 62-141889 has concerns about the adhesive strength between the silicone resin adhesive and the metal even after cleaning and primer treatment, and it is difficult to fix the glass plate. A widening groove is provided in the frame body, and the adhesive that hardens inside the groove functions as an anchor. The drawback was that it was time consuming. (Means for solving the problem) The present invention was made to solve the above-mentioned problem, and the periphery of the glass plate is held by a frame fixed to the opening of the building frame through an adhesive. The present invention provides a glass plate mounting structure in which the frame is framed by a plate-like body made of a non-metallic material, and the glass plate is bonded to the end face of the plate-like body. It is effective that the plate-shaped body is made of one or a combination of glass, ceramics, or stone, and that the adhesive is made of a structural sealing material. (Example) Hereinafter, an example of the present invention will be described based on the drawings. Figure 1 is a perspective view of a partially cut out glass plate glued to the end face of the frame in one embodiment of the present invention;
The figure shows a longitudinal sectional view of one embodiment of the present invention that is fixed to a building frame. The opening of the frame 1 made of a concrete structure is provided with a frame 5 by pasting a plate-shaped body 2 having a certain thickness around the opening, but the attached state is that of a strip-shaped plate-shaped body. 2 to setting block 3
The frames 5 are arranged on the circumferential surface of the opening and adhered by an adhesive 4 which is injected and filled from inside or outside the room to form and fix the frame 5. A glass plate 6 is vertically disposed on the outdoor side of the frame, and the end of the frame 5, that is, the end surface of the plate-like body 2 and the glass plate 6
A structural sealing material 7, which is a structural adhesive, is injected and filled into the gap between the edge of the glass plate 6 and the glass plate 6 is attached by curing and curing. The plate-like body 2 is a thick molded plate made of glass, ceramics, stone, etc., and there are spaces between the plate-like body 2 and the frame 1, that is, concrete, and gaps between the arranged plate-like bodies, that is, The adhesive 4 injected into the joint is a silicone sealant for construction and civil engineering, and is adhered by hardening. For window glass with a relatively small opening area, the plate-like body 2 is assembled in a rectangular shape as shown in FIG. By filling the gap between the structural sealing material 7 and the glass plate 6 and curing and hardening, it becomes an integrated box-shaped frame.The box-shaped frame is inserted into the opening of the frame 1, and the frame and the plate-shaped body are combined. The adhesive material 4 is injected and filled into the gap between the glass plate 6 and the glass plate 6, resulting in a window glass without a sash around the glass plate 6. The strip-shaped plate bodies 2 arranged around the opening are
A single plate may be used instead of a strip of paper, or a frame may be formed by combining glass with other similar materials, and adhesives 4 of various colors may be combined at the joints. Adhesive material 4 is a low modulus silicone sealant that also serves as a weather seal, and structural sealant 7 is used to bond the glass plate 6.
It is preferable to use a high modulus type silicone sealant with high adhesiveness. The joint design value is determined by taking the design wind pressure and the size of the glass plate 6, that is, the joint allowance for the wind pressure, the thickness and depth dimensions such as the joint width calculated for the amount of interlayer displacement, and filling the gap. The operation of the present invention will be explained below. The mounting structure in which the end face of the plate-shaped body 2 and the edge of the glass plate 6 are bonded and held by the structural sealing material 7 is made of a material that has reliable adhesive strength in combination with the structural sealing material 7, that is, the glass plate 6 Alternatively, by constructing the frame 5 with a plate-like body 2 made of a similar material, the phenomenon of interfacial peeling between a silicone sealant and a metal can be eliminated, and the adhesive strength can be maintained even against wind pressure applied to the glass plate 6. Using a high-quality structural sealing material 7, this sealing material absorbs the amount of interlayer displacement, is smooth and has excellent workability, and has excellent design.
By filling the area around the joint adhesive 4 for the purpose of weather sealing, water and air sealing properties can be maintained. Depending on the size of the opening, the frame 5 and the glass plate 6 may be bonded together and cured in advance at a factory, and the integrated structure may be attached to the frame 1 to ensure dimensional accuracy and easy on-site construction. The construction period can also be shortened. Note that there is also a method of embedding the mounting structure of the frame body 5 in concrete instead of the adhesive material 4, but a supporting method that can withstand wind pressure must be considered. (Effect of the invention) The mounting structure according to the invention using adhesive material is
By using glass or a similar material on the surface to be bonded and eliminating the need for metal parts, the bonding reliability is extremely high, and this makes it possible to meet requirements such as wind pressure, interlayer displacement, moisture, and airtightness. In addition to the ease of work achieved by the saturationless window glass, it also has excellent design features and eliminates the phenomenon of thermal cracking.
