Description

[Detailed description of the invention] double glazed window fittings Main skin food R member The present invention relates in more detail to the installation of double glazed window units in buildings. includes a secondary attachment means for attaching sealed double glazed window units to a building structure. That is, it relates to a device that provides secure attachment means.

Glass units made from two, and sometimes more, glass panes are well known. be. These glass units are, in detail, two pieces of glass spaced apart. It is used as an insulating glass unit sealed to each other. two galas The spacers are separated by spacers, and these spacers extend around the entire perimeter of the glass combination. are attached to each glass. Thus, these glasses are typically Air or other gases are trapped between two pieces of glass and are firmly attached to the unit. , ensure the insulation of the unit.

Office buildings often use fairly large glass units, e.g. extending from floor to ceiling. A glass unit that expands may be used. Building glass units like this Many different techniques have been developed to attach the The glass unit is installed using a doped camp or outdoor stopper. child These end camps or struts are located on the exterior glass of the unit and are constructed Anchored to an object and reframped. This type of installation means that the mechanism is e.g. This is shown in National Patent No. 3367077, but this patent includes a double glazing unit. is not mentioned.

According to the above method, the glass unit can be installed very well in the building. However, many buildings install the unit without an outdoor strike, bar or cap. You need to install. One common way to accomplish this is with the unit This is a method of directly attaching the guide side glass to the building. This can be done on-site or in production. Attach the unit to the frame far away from the job site, then attach the frame to the building. This can be done by attaching the unit to the appropriate location (generally referred to as unitization). Wear. In either case, the structural adhesive used is typically a primary or secondary component type. A silicone sealant, preferably a fast curing silicone sealant. child Apply a sealant around the entire perimeter of each unit to weather-proof the unit against the building structure. -Seal.

It is of course easy to see that the entire weight of the unit is supported by the sealant. Similar to the stretching forces imposed by the expansion and contraction of the inner glass, which may Supported directly by sealant.

If the sealant is unfortunate enough to fail, the entire unit will fall off the building.

This potentially catastrophic failure of the sealant around the glass unit are typically difficult to detect unless leakage elements are observed in the building; Roots of sealant failure if not properly surfaced for good adhesion. Good bonding is difficult to complete and inspect on site, as shown during construction. Ru. Although four-sided fixed silicone systems are attractive to industry, they are still This proved to be inconvenient for these reasons.

Matasato Mai! The main objective of the invention is that it can be easily used with standard glass units and frames. , easy to install, eliminates the need for end camps or outdoor stops, and is flexible For double-glazed glass units that use a connector member as a mounting means component The objective is to provide a reliable and reliable mounting means. double glazed glass The main means of attachment for the unit, e.g. to reinforce structural silicone adhesives. A more specific aspect of this primary purpose is to apply it as an attachment means such as a secondary attachment means. It is.

This purpose is received in the groove formed between the glass plates of the glass unit of double glazing. and a second portion extending beyond the perimeter of the glass unit. The second part of the zero elastic member achieved by the invention with an elastic or flexible member The portion is fixed to the structure to which the glass unit is to be installed, for example a building.

The means for securing the resilient member to the building structure advantageously take the form of a separate anchor member. The anchor member can be fixed to the building, and the second part of the elastic member The fit of this embodiment is a tongue/groove engagement with a resilient member and an abutment. A mutual sliding fit between complementary contoured portions of the anchor member is used.

In this embodiment, the elastic member is an elongated block of rubber or elastic material such as EPDM. It is This block is typically located between the glasses in a double glazed glass unit. a first portion sized to fit into a recessed groove formed around the periphery of the unit; have The second portion of the block extends beyond the perimeter of the glass unit. this The second part includes one, preferably more lateral (i.e. glass unit) is formed with a contoured surface having a flange or ridge extending at right angles to the general plane of the There is.

The anchor member used in this example is an L-shaped metal bracket. L shaped bra The base of the bracket is fixed to the building, for example by welding it to the mullion. Ru. The other part of the L-shaped bracket has a table that is complementary to the surface of the second part of the block. Surfaces are formed to allow the blocks and anchors to fit and interlock with each other. For example, a concave groove is formed on the surface of the L-shaped bracket in this example. This groove has one of the flanges of the block with tongue/groove interengagement. Acceptable.

The above fittings are suitable for installing such double glazing units in buildings. found a specific use. There are multiple connectors spaced around the glass unit. Positioned in a flat relationship. In this regard, the present invention provides Using silicone adhesive, which can also be easily applied as the main mounting means It is said that it is most useful as a secondary attachment means, that is, a safety attachment means for the main attachment. Conceivable. That is, the glass units are attached to the building using traditional methods with adhesives. The connector of the present invention can be used as a back-up amplifier in case the adhesive is damaged. . When so applied, the glass unit is fitted in place using standard techniques. or can be attached to a building in a unitized structure.

By welding the anchor's L-bracket to the mullion, for example, the unit can be position around the perimeter of the block and secure it in place.The installation then begins with the first insert the second part into the groove between the glass plates and the second part into the complementary recess of the L-shaped bracket.
