Aging device and aging method for hidden framing glass curtain wall

Abstract

The invention discloses an aging device and an aging method for a hidden framing glass curtain wall. The aging device comprises an experimental test work box, an ultraviolet control system, a temperature control system and a main control system, the ultraviolet control system, the temperature control system and the main control system are arranged on the side surface of the experimental test work box, the experimental test work box is used for placing a hidden frame glass curtain wall unit, and the ultraviolet control system and the temperature control system are controlled by the main control system; the ultraviolet control system and the temperature control system generate ultraviolet rays and temperature so as to accelerate aging of the glass curtain wall in the experimental test work box, and irradiance and temperature information in the experimental test work box is fed back to the main control system. The device is easy to assemble, facilitates the carrying of the hidden frame glass curtain wall unit in the testing process, and solves the problem that the existing aging equipment can only accelerate the aging of I-shaped pieces and dumbbell-shaped test pieces with specific sizes, but cannot be used for the aging of the full-scale hidden frame glass curtain wall unit.

Description

technical field [0001] The invention relates to the field of building structural adhesive testing, more specifically to an aging device and aging method for hidden-frame glass curtain walls. Background technique [0002] Architectural curtain wall integrates technology and art, decorates urban space with unique artistic expression, endows buildings with new aesthetic connotations, and has become an important symbol of modern architecture. During the whole life cycle service of the building curtain wall, the overall performance of the curtain wall gradually declines under the coupling effect of ultraviolet radiation, cold and heat cycle, wind load and other factors. social influence. Evaluating the safety performance of building curtain walls has become a topic that cannot be ignored in urban public safety research. [0003] Hidden frame glass curtain wall is a kind of building curtain wall. Its panel material is tempered glass. The horizontal and vertical frame members are...

Problems solved by technology

However, this research method cannot be used in the research of full-scale curtain wall units, mainly for three reasons: First, the research objects are different, and I-shaped and dumbbell-shaped specimens of specific sizes cannot replace full-scale curtain wall units, especially silicon When the ketone structural adhesive is used as the boundary constraint of the curtain wall panel to study the vibration characteristics of the panel, it is necessary to study the full-scale curtain wall unit as a whole; second, the existing aging equipment has a single function, which is used for I-shaped and dumbbell-shaped The standard aging box cannot meet the aging requirements of the curtain wall unit; third, the real stress state of the silicone structural adhesive cannot be simulated, and the glass curtain wall panel is affected by wind load and self-weight load, so that the silicone structural adhesive is subjected to a combination of tensile and shear forces. The action presents a complex stress state, which cannot be realized in the existing aging box
