Description

Glass panel for curtain wall and curtain wall construction method using it {Shop Glazing System by Structural Silicone in Stick System Curtain Wall}

The present invention is for constructing a glass-finished outer wall using structural sealant in a stick system curtain wall, and in particular, pre-fabricated assembled glass panel in which a structural sealant is filled by skilled workers in a factory having excellent working environment (shop-glazing). Then, the construction of the curtain wall by assembling it to the curtain wall frame structure installed in the field is not only easy to install, but also a part (pillar, concrete retaining wall, spandral part) where the conventional structural sealant was poorly injected. The present invention relates to a glass wall assembly panel for curtain walls and a curtain wall construction method using the same.

Conventionally, in the construction of the outer wall of the structure in which only the glass is visible on the outer wall of the building using the structural sealant in the stick system curtain wall, as shown in Figure 1,

After installing the vertical member (2) and the horizontal member (3) to the building structure (1) to form a curtain wall frame,

After adhering the adhesive gap holding member 4 to the outer surface of the vertical member 2 and the horizontal member 3 forming the curtain wall frame,

The glass 5 is attached and temporarily fixed to this gap holding material 4,

Filling and filling the structural sealant (6) in the space between the curtain wall frame formed by the spacer and the glass (5),

In order to prevent the glass 5 from falling off until the structural sealant 6 is cured and exhibits a predetermined adhesive strength, the pressing plate 7 is attached to the protruding piece 2a of the vertical member 2 by the binding pin 8. To hold the glass (5),

When the structural sealant 6 has the required adhesive strength, it has been constructed in such a way that the pressing plate 7 and the binding pin 8 are removed.

However, in the related art, the vertical members 2 and the horizontal members 3 are formed in the building structure 1 due to the nature of the work in which the structural sealant injected between the curtain wall frame and the glass 5 must be injected from the interior side of the building. In the case of the column, the concrete retaining wall, and the spandral portion, the structural sealant 30 has been impossible to be injected.

In particular, the structural sealant 6 injected between the glass 5 and the curtain wall frame is dependent upon the gap retaining material 4 bonded between the glass 5 and the curtain wall structure until the desired adhesive strength is achieved. In order to withstand the weight of the building and the wind load on the exterior of the building, the loads on the bonding strength of the spacer 4 are not fully supported in this process and adversely affect the structural sealant 6 which is in progress. The original bond strength cannot be sufficiently exhibited, and the subsidiary work is caused due to the irrationality in which the performance of the structural sealant 6 depends on the skill of the field technicians.

In addition, because the glass must be attached in a high altitude of poor working environment, there are various problems such as failing to take advantage of the curtain wall system that finishes the outer wall of the building with glass, and the finishing surface is uneven to reduce the aesthetic effect.

Accordingly, the present inventors in order to solve the problems caused by injecting the structural sealant of the concrete retaining wall, column, spandral part in the field in the prior art of constructing the glass finish type by the stick system curtain wall, The present invention has been devised to exclude the injection of structural sealants in the field.

Therefore, the object of the present invention is to fill the structural sealant by skilled workers in a factory with excellent working environment and completely harden it until the bonding strength required in the curtain wall is obtained. Is to provide prefabricated glass panels manufactured in the factory so that they can only be assembled.

Another object of the present invention is to use the assembled glass panel, not only easy construction, but also ensure structural stability, using the assembled glass panel to maximize the aesthetics of the building appearance according to the glass finish type in the stick curtain wall system To provide a curtain wall construction method.

The present invention for achieving the above object is to form a curtain wall frame by connecting the vertical and horizontal members of the aluminum extruded material in a lattice form on the building structure of the site, and separately from the fixing frame on the back edge of the glass panel in the factory After fabricating the assembled glass panel by attaching it with sealant, the assembled glass panel is transported to the site and fixed to the vertical and horizontal members of the curtain wall frame installed on the site through fixtures and fixing screws. It is done.

Hereinafter, the technical configuration of the present invention will be described in detail with reference to the accompanying drawings in accordance with an embodiment of the present invention.

Assembled glass panel according to an embodiment of the present invention, as shown in Figures 2 to 4, the four-sided glass panel 10, which is processed to be installed as the outer wall plate material of the curtain wall, along the outer side of the four sides The fixed frame 20 is assembled into a rectangular frame having a channel-shaped groove 21 and attached to the rear edge of the glass, and the glass panel 10 and the fixing frame 20 are placed on both sides thereof, and enter into a predetermined thickness between them. It is characterized by consisting of a structural sealant 30 is filled with two members attached to each other.

The fixing frame 20 is cut into lengths corresponding to the four sides of the glass panel 10 and assembled into a channel steel, and an aluminum extrusion material is used as the channel steel.

The channel-shaped groove 21 is formed on the outer side of the channel steel, and the gasket groove 22 is formed on the inner side.

The fixing frame 20 is formed by the grooves, the channel-shaped groove 21 is formed on the four outer sides of the four sides, the inner side is completed with a four-sided frame formed with a gasket groove 22.

Both ends of the channel steels are cut at an angle of 45 ° so that neighboring ones are assembled to each other.

The four corners of the channel-shaped grooves are joined to the channel-shaped groove 21, the corner stiffener 23 is made of an angle plate is inserted and then screwed to reinforce at the same time to connect the adjacent channel-shaped steel.

Between the glass panel 10 and the fixing frame 20 based on the exact structural calculation, the gap retainer 40 having a predetermined thickness and adhesiveness on both sides before the sealant 30 is filled. It enters inside and is primarily bonded

The glass panel 10 and the fixing frame 20 are bonded to each other by filling the sealant 30 evenly in the spaces between them while a predetermined interval is maintained by the gap maintaining material 40.

The glass panel 10 and the fixing frame 20 integrated with the structural sealant 30 are maintained to maintain the correct level until the structural sealant 30 is completely cured to fully exhibit a given adhesive strength.

Therefore, the assembled glass panel 100 according to the present invention is manufactured in a factory in which all products are standardized to a certain quality according to the design of the curtain wall.

Curtain wall construction method according to an embodiment of the present invention, as shown in Figures 5 to 8, the channel-shaped grooves 21 along the outer side of the glass panel for the curtain wall 10 and the four sides in the factory as described above After joining the fixing frame 20 having a structural sealant 30 to manufacture the assembled glass panel 100, the assembled glass panel 100 is transported to the site of the channel-shaped groove of the neighboring assembled glass panel 100 ( The fittings 200 are inserted in half at regular intervals 21, and the fixtures 200 are disposed on the vertical members 300a and the horizontal members 300b of the curtain wall frame which are tightly installed in a grid structure on the building structure S of the site. ) By fastening the fixing screw 400 to the fixing frame 20 of the assembled glass panel 100 to the vertical member (300a) and the horizontal member (300b) through the operation, the glass wall frame to the frame It characterized in that the installation (10).
