The present invention relates to a support device for a glass curtain wall, particularly to a waterproof support device for a dual-layer glass curtain wall.
With sophisticated glass fabrication technology, glass also greatly advances in usage safety in addition to its original superior transparency. Therefore, modern buildings widely adopt glass curtain walls, which benefit interior lighting and filter ultraviolet ray. The glass curtain wall is usually installed in the building with a support device. Refer to
A Taiwan patent No. M303964 disclosed a conventional support device for a glass curtain wall, which comprises a column, a clamp ring, and a top brace. An annular block member extends from one end of the column. The column passes through a via-hole of a piece of glass. A buffer pad is interposed between the block member and one surface of the glass. The block member has at least one elastic flange on the surface facing the glass. Another buffer pad is interposed between the clamp ring and the other surface of the glass. The clamp ring and the block member will together clamp the glass tightly. One end of the top brace is integrated with the column. The two flanges of the support device will be deformed by the clamping force of the clamp ring and the block member to compensate the gaps between the glass and the column and form an airtight/waterproof structure. However, the top brace and the clamp ring are screwed together via the threads thereof, and there is none airtight/waterproof element in the threads, and water will still enter via the threads. Thus, in addition to water leakage, the threads will rust. When the support device is used in a dual-layer glass, humidity will enter the gas between the two pieces of glass, and vapor will condense on the glass, and the transparency of glass is thus decreased.
The primary objective of the present invention is to secure the installation of a dual-layer glass curtain wall and to prevent humidity from entering the gap of the dual-layer glass curtain wall to attain a full airtight/waterproof function.
To achieve the abovementioned objective, the present invention proposes a support device for a dual-layer glass curtain wall, which is used to support a dual-layer glass curtain wall and provides an airtight/waterproof function for the gap of the dual-layer glass curtain wall and comprises a column, a clamp member sleeving the column, and a top brace installed inside the column. The outer surface of the column has an external thread. The column has a block member horizontally extending from the bottom of one end, and a packing ring is arranged in the root of the block member. The other end of the column has an inward-concaved cavity, and a fixing element is accommodated in the upper part of the cavity. The cavity and the fixing element respectively have threads, which can screw along each other. The clamp member further comprises a first press element pressing against the block member of the column, a second press element having an inner thread corresponding to the external thread, and a press ring interposing between the first press element and the second press element. Further, two press plates are respectively arranged between the first press element and the press ring and between the press ring and the second press element. A packing ring is arranged in the second press element and near the inner thread and faced to the press ring. When the first press element presses the block member and the second press element presses the press plate, the two packing rings are deformed to compensate the gaps of the structure; thus, the airtight/waterproof objective is achieved. Therefore, the support device for a dual-layer glass curtain wall of the present invention not only can firmly secure a dual-layer glass curtain wall to a fixing element on a building but also can prevent humidity from entering the gap of the dual-layer glass curtain wall.
The technical contents of the present invention are to be described in detail in cooperation with the drawings below.

To intensify the airtight/waterproof function of the support device for a dual-layer glass curtain wall of the present invention, at least one packing ring 211/224 is installed on the first/second press element 21/22 and contacts the press plate 24/25; at least one packing ring 241/251 is installed on said press plate 24/25 and faced to the press ring 23; at least one packing ring 232/233 is installed on the press ring 23 and faced to the press plate 24/25. The packing rings 211, 224, 232, 233, 241 and 251 are made of elastic material and will be deformed by a pressing force. Thus, the packing rings will closely contact the surfaces. Therefore, humidity will neither enter the structure of the support device for the dual-layer glass curtain wall 40 nor enter the gap 41 of the dual-layer glass curtain wall 40.
The present invention utilizes the clamp member 20 to firmly fix a dual-layer glass curtain wall 40 to the building and utilizes a plurality of packing rings 13, 211, 223, 224, 232, 233, 241 and 251 to prevent humidity from entering the structure of the support device for the dual-layer glass curtain wall 40 or the gap 41 of the dual-layer glass curtain wall 40. Therefore, the present invention can fully achieve the airtight/waterproof objective. Via inhibiting humidity entering the structure of the support device of a dual-layer glass curtain wall, the present invention not only can prolong the service life of the support device of a dual-layer glass curtain wall but also can prevent the transparency of a dual-layer glass curtain wall from being degraded by vapor.
Those described above are the preferred embodiments to exemplify the present invention. However, it is not intended to limit the scope of the present invention. Any equivalent modification or variation according to the spirit of the present invention is to be also included within the scope of the present invention.
