The present invention relates to the bolt fastening structure of the laminated glass laminated glass, to enable the construction of the front plate to the thin plate through the reinforcing strength of the laminated glass being constructed by the Special Point Glazing system.

In general, the exterior wall finishing method of high-rise buildings is making full use of the advantages in design, structure, construction, etc., and the front or side glass buildings based on the curtain-wall method are becoming common. Most of these buildings have a light and beautiful exterior, which makes the aesthetics of the city more clean and lively.

On the other hand, if you look closely to the recent windshield or horizontally extending continuous windows in detail, the number and size of the window frames noticeable in the conventional window frame method is gradually decreasing, and attempts to conceal the window frame on the back of the glass as much as possible. These efforts have evolved into SPG (Special Point Glazing), SSG (Structural Sealant Glazing), and SGS (Structural Glazing System), and are actively spreading not only in Europe and Japan but also in Korea.

The special point glazing system is a state-of-the-art construction that supports the structure with glass, rod truss, wire and stainless pipe inside because the surface of the glass is flat because it combines the specially processed bolts with the grooved grooves. .

This Special Point Glazing system maintains excellent safety without using a frame or structural silicone, and has an excellent design to maximize the natural beauty of the building, and to ensure maximum openness and lightness.

Generally, the glass used in the Special Point Glazing system includes single glass, laminated glass, and laminated glass.

The use of multi-layer glass in the Special Point Glazing system creates a space layer between the front panel and the back panel, which provides good sound insulation and insulation effect. Its quality and delivery time can be improved, and the airtightness and watertightness are excellent by sealing around the hole with butyl and silicone.

On the other hand, in recent years, attempts to improve the construction efficiency by reducing the construction cost and processing cost by reducing the thickness of the glass to be thinner, and weight reduction, but the thickness of the glass 10mm due to the strength reinforcing bolt coupling structure There was a problem that the design is difficult below.

In other words, when machining a bolt hole in a predetermined position of the glass, the mounting groove in which the bolt head is seated should be processed together. In the conventional case, the thickness of the glass is reduced because a stress concentration part occurs according to the glass load. There was a limit.

The present invention has been proposed to improve the above problems in the prior art, by providing a fastening structure capable of evenly dispersing the stress while maximizing the bonding force between the glass and the fastening bolt during the construction of the multilayer glass sheet thickness of the glass The purpose is to enable processing.

The object is a multi-layered glass fastening structure in which the front plate and the back plate made of a transparent body are integrally coupled by the coupling force of the fastening bolt and the end nut in a state where they are spaced apart from each other by a spacer, wherein the front plate penetrates the fastening bolt. A fastening hole for insertion is formed, and curved grooves are formed on both upper and lower peripheral portions of the fastening hole; The fastening bolt is provided with a head to be seated in the curved groove, the bottom surface of the head is formed in a curved shape corresponding to the curved groove; At the other side of the fastening hole, the bottom plate is fastened to the fastening bolt, and the fastening is performed. The upper surface of the bottom plate has a bolted structure for strengthening the multi-layer glass, characterized in that the curved part is formed at the portion corresponding to the lower curved groove. This can be achieved through

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, looking at the bolt fastening structure of the multilayer glass according to the present embodiment, the front plate 1 and the back plate 3 made of 6mm tempered glass bolt holes (2, 4) in the predetermined position at the same position, respectively Among them, in the bolt hole 2 of the front plate 1, curved grooves 2a and 2b having a predetermined curvature shape are formed in the upper and lower portions, respectively, in a symmetrical form.

In addition, a spacer 50 for space support is configured between the front plate 1 and the rear plate 3, and a bottom plate 20 mounted on the lower curved groove 2b is provided. The spacer 50 forms a sealing space 52 so that the bolt hole 51 is formed in the center thereof and the sealing agent S is filled around the bolt hole 51.

And, the lower plate 3 is provided with a washer 30 and the end nut 40 for the final fastening with the fastening bolt 10.

On the other hand, the fastening bolt 10 to be used to couple the parts integrally has a circular head portion 11 at the top of the center forming a screw portion 12 for fastening with the end nut 40 at the end; However, the head portion 11 forms a protruding curved portion 10a having the same curvature as the curved groove 2a formed in the glass surface.

In addition, the bottom plate 20 also has the same curved portion 20a on the top surface as the curved groove 2a on the front plate 1 side.

The silicon coating layers 13 and 23 are formed on the curved portion 10a of the bottom of the head 11 corresponding to the curved grooves 2a and 2b and the curved portion 20a of the upper surface of the bottom plate 20, respectively. It is preferable to prevent the generation of stress on the glass surface due to the pressing force.
