Description

Technical Field

[0001] This utility model relates to the field of glass curtain wall technology, and in particular to a glass curtain wall structure using glass fiber reinforced composite materials. Background Technology

[0002] A glass curtain wall is a building structure composed of glass panels and a supporting structure, primarily serving functions such as enclosure, lighting, and decoration. As a major external envelope structure of modern buildings, the thermal insulation and energy-saving performance of glass curtain walls directly affects the building's energy consumption, indoor comfort, environmental friendliness, and long-term economic viability.

[0003] Currently used insulated glass curtain walls primarily improve their thermal insulation and energy-saving effects by modifying the glass structure. For example, patent CN208347070U describes a glass curtain wall insulation structure that incorporates an air gap between the inner and outer glass panes, with a thermal insulation strip fixed within this gap. The glass curtain wall uses this thermal insulation strip to insulate against external high temperatures, thus improving its insulation performance. However, the supporting structure of the glass curtain wall also increases heat transfer, leading to higher energy consumption. Current support structures use thermal break bridges to improve insulation performance, but due to the increasingly severe energy situation and higher requirements for building energy conservation, the thermal conductivity of thermal break bridges is insufficient to meet current requirements. Therefore, it is necessary to use fiberglass reinforced composite materials with lower thermal conductivity and higher structural strength in the support structure.

[0004] Therefore, it is hoped that a glass curtain wall structure using fiberglass reinforced composite materials can solve the problems existing in the current technology. Utility Model Content

[0048] Step (5): Install the energy-saving insulating glass 1. Install the energy-saving insulating glass 1 on both sides of the first fiberglass reinforced composite connector 3.

[0049] Step (6): Select a suitable steel vertical pressure plate 4, set a first through hole in the middle of the vertical pressure plate 4, set mountain-shaped protrusions on both sides, and install the extruded second vertical sealing strip 11 in the mountain-shaped protrusions of the vertical pressure plate 4.
