Refractory glass thermal-insulation frame positioning structure

Abstract

The invention discloses a refractory glass thermal-insulation frame positioning structure. The refractory glass thermal-insulation frame positioning structure comprises a sectional material spliced frame used for positioning the edge of refractory glass, wherein a cavity for containing the edge of the refractory glass is formed in the sectional material spliced frame, and fireproof flame-retardant rubber strips attached to the refractory glass are fixed to the parts, on the two sides of the cavity, of the sectional material spliced frame; a refractory glass edge protecting frame is fixed to the part, at the bottom of the cavity, of the sectional material spliced frame and provided with a positioning clamping groove for clamping the edge of the refractory glass. The refractory glass thermal-insulation frame positioning structure is characterized in that a thermal-expansion graphite band is attached to the sectional material spliced frame, and the cavity is filled with the thermal-expansion graphite band after thermal expansion. The thermal-expansion graphite band is attached to the sectional material spliced frame, the cavity for positioning the refractory glass is filled with the graphite band after thermal expansion, the graphite band is expanded to reinforce the refractory glass and obstruct heat transfer, the fireproof flame-retardant rubber strips are protected, and the refractory glass thermal-insulation frame positioning structure is prevented from separating from the refractory glass; in this way, the positioning stability of the refractory glass is greatly improved through the whole structure, and then the flame-retardant and thermal-insulation performance of the refractory glass is further improved.

Description

technical field [0001] The invention belongs to the technical field of fire-resistant glass installation structures, and in particular relates to a fire-resistant glass heat-insulating frame positioning structure. Background technique [0002] In the prior art, during the construction of buildings and indoor structures, the sides of fire-resistant glass are positioned by profile splicing frames. This profile splicing frame has concave cavities for the sides of fire-resistant glass to be inserted. The fire-resistant and flame-retardant adhesive strips attached to the fire-resistant glass are fixed on the profile splicing frames. In this frame positioning structure, the fire-resistant and flame-retardant adhesive strips between the fire-resistant glass and the profile frame play the main role of fixing and flame-retardant heat insulation. [0003] However, in actual use, the above frame positioning structure gradually exposes the following defects: [0004] When a fire break...

Problems solved by technology

[0004] When a fire breaks out, the heat is easily transmitted to the area where the cavity is located through one side of the splicing frame of the profiles, causing the profiles in this area to expand and deform, which in turn leads to fire-retardant adhesives Strips are detached from fire-resistant glass

However, due to the lack of further positioning structure between the profile splicing frame and the refractory glass, once the adhesive strip is disengaged and fails, the positioning stability of the refractory glass will be greatly reduced. insulation function

[0005]In addition, although the profile splicing frame is equipped with a profile heat insulation cavity to slow down heat transfer, the flame retardant and heat insulation effect is still insufficient, and heat and flame are particularly easy to pass through. This type of material insulation cavity enters the inside of the frame and is transferred quickly, resulting in a decrease in the stability of the entire profile splicing frame
