Description

Node construction device for energy-saving transformation of glass curtain wall

technical field

The invention relates to a connecting device for installing an inner glass curtain wall.

Background technique

As a new form of contemporary building exterior wall, glass curtain wall is widely used because of its large lighting area, beautiful appearance and good decorative performance. However, the glass curtain wall is also an important part of building energy loss, and its heat transfer coefficient is relatively large. The energy consumption of transparent curtain walls is about three times that of ordinary walls, accounting for 40% to 50% of the total energy consumption of building envelope components. Therefore, , the energy-saving transformation of existing building curtain walls has become one of the important breakthroughs in my country's building energy conservation.

However, the glass curtain wall renovation of existing buildings will generally affect the use of internal functions of the building, the process is complicated, the construction efficiency is low, and the renovation cost is high.

Contents of the invention

The object of the present invention is to provide a node structure device for energy-saving transformation of glass curtain walls in order to solve the problems of poor thermal insulation performance and high building energy consumption of existing building single-layer glass curtain walls.

Shaped veneer and right stepped veneer enclose a convex-shaped cavity inside. The upright column is in the shape of a rectangular tube filled with thermal insulation cotton. The upright column is set on the internal building structure and passes through the left stepped veneer and right In the cavity surrounded by stepped veneers, a connecting insert is embedded between the left stepped veneer and the right stepped veneer and the outer wall of the column. The vertical frame of the built-in glass curtain wall is clamped and fixed by bolts on the left In the cavity convex formed by the stepped veneer and the right stepped veneer, the left stepped veneer and the right stepped veneer are respectively fixed on the internal building structure through connectors.

The node construction device used for energy-saving transformation of building glass curtain walls is a structural design that facilitates adding an inner glass curtain wall to the inner side of the existing glass curtain wall. It can be applied to the renovation of existing buildings and the construction of new buildings. The vertical frame of the newly added glass curtain wall is connected to the building structure through the node structure device, so as to achieve the overall improvement of energy-saving performance. This node is simple in structure, convenient for construction, and can effectively improve engineering efficiency.

The invention solves the problems of poor thermal insulation performance and high building energy consumption of the single-layer glass curtain wall of the existing building. The inner glass curtain wall can be added on the inner side of the original glass curtain wall through the node construction device. Connect the vertical frame with glass curtain wall inside to the building structure, realize the curtain wall system of inner and outer double-layer glass curtain walls without destroying the original glass curtain wall, affecting the use of the building and changing the appearance of the building, significantly reducing the construction of energy-saving renovation difficulty.

The present invention can independently regulate the distance between the inner and outer glass curtain walls according to the requirements of building renovation, so as to facilitate targeted adjustment of the building interior environment according to the actual building use conditions. At the same time, the inner glass curtain wall can also cooperate with the outer glass curtain wall or other structural devices. For example, it can cooperate with the outer glass curtain wall to form a double-layer breathing curtain wall to further enhance the ventilation effect of the building. It can also be combined with translucent roller blinds to adjust the indoor temperature and light environment of the building.
