Description

TECHNICAL FIELD

[0001] The utility model belongs to vacuum glass technical field relates to the fireproof structure for vacuum glass. BACKGROUND

[0002] Vacuum glass is a new type of glass deep processing product, which is developed based on the principle of thermos bottle. The structure of vacuum glass is similar to that of hollow glass, and the difference lies in that the gas in the cavity of vacuum glass is very thin, almost close to vacuum. The vacuum glass is sealed around the two flat glass plates, and the gap therebetween is pumped into vacuum and sealed exhaust hole. The two plates of vacuum glass are generally at least one low-emissivity glass, so as to minimize the heat loss through the conduction, convection and radiation modes of vacuum glass. The working principle is the same as that of the heat insulation principle of glass thermos bottle. Vacuum glass is the result of cooperation and coordination of glass technology, material science, vacuum technology, physical measurement technology, industrial automation and building science, and various disciplines, technologies and processes.

[0003] The conventional vacuum glass can achieve good sound insulation effect through the characteristic that sound cannot be transmitted in a vacuum environment, but in a fire, the external high temperature will rapidly heat the outer layer of the vacuum glass. Due to the existence of the vacuum layer, the heat cannot be effectively transmitted to the inner layer by convection or conduction, resulting in rapid temperature rise of the outer glass. In this case, the outer glass will be subjected to strong thermal stress, because the temperature difference between the inner and outer layers will cause uneven expansion of the material, thereby generating high stress concentration, leading to breakage of the outer glass and causing secondary injury.

[0004] Therefore, it is necessary to design a fireproof structure for avoiding breakage of vacuum glass due to uneven expansion under high temperature in a fire. INVENTION CONTENTS

DETAILED DESCRIPTION

[0021] The present application will be described in detail below in combination with the drawings and specific embodiments.

[0022] Example 1:

[0023] like Figure 1 As shown, it includes a strip-shaped fireproof box 1, such as Figure 2 As shown, the fireproof box 1 contains a collection column 2, which is filled with thermally conductive adhesive. A squeezing rod 3 runs through the side wall of the fireproof box 1. A drain groove 4 is provided on the side of the fireproof box 1 along its length. A glass fixing groove 5 is provided on each side of the drain groove 4 along the length of the fireproof box 1. A U-shaped frame 6 is fixedly connected to the outer wall of the fireproof box 1 where the drain groove 4 is located, and the two ends of the U-shaped frame 6 are fixedly connected to the outer wall of the fireproof box 1.

[0024] Each of the two glass fixing slots 5 has a piece of glass fixed in it. When in use, pressure is applied to the extrusion rod 3 to puncture the collecting adhesive column 2, causing the heat-conducting adhesive inside to flow out and into the gap between the two glass pieces through the drainage groove 4, thereby improving the heat conduction between the two glass pieces.

[0025] Example 2:

[0026] Based on Example 1:

[0027] like Figure 2 As shown, a V-shaped support frame 7 is fixedly connected to one end of the extrusion rod 3 on the outside of the fireproof box 1, and the opening of the support frame 7 faces the fireproof box 1. The extrusion rod 3 is connected to the center of the support frame 7, and both ends of the support frame 7 abut against the surface of the fireproof box 1.

[0028] The support frame 7 is made of a flexible metal sheet.

[0029] The support frame 7 keeps the extrusion rod 3 away from the collection column 2, preventing the extrusion rod 3 from accidentally puncturing the collection column 2 and causing leakage of the thermally conductive adhesive unnecessarily, resulting in unnecessary waste. At the same time, the elastic support frame 7 can return to its original position after being pressed, preventing the extrusion rod 3 and its connected components inside the fireproof box 1 from being in the center of the fireproof box 1 for a long time, which would affect the flow of the thermally conductive adhesive.

[0030] Example 3:

[0031] Based on Example 1:

[0032] like Figure 2 As shown, a fixing plate 8 is fixedly connected to one end of the extrusion rod 3 located inside the fireproof box 1. Four rows of puncture needles 9 are fixedly connected to the side of the fixing plate 8 facing the receiving glue column 2 along the length of the fireproof box 1.

[0033] The fixed plate 8 can provide greater pressure to ensure that the assembled glue column 2 is pierced to make the heat-conducting glue flow out, and the fixed plate 8 is used to connect a plurality of piercing needles 9 to pierce the assembled glue column 2 from different points to make the heat-conducting glue flow uniformly to the drainage groove 4 and enter between the two glasses, thereby avoiding the problem that part of the heat-conducting glue preferentially contacts the glass to cause part of the glass to rapidly drop in temperature and break due to the increase in thermal stress.

[0034] As shown in Figure 2 , the inner wall opposite to the piercing needle 9 in the fireproof box 1 is fixedly connected with a fixed adhesive plate 11, and one side of the fixed adhesive plate 11 facing the inner side of the fireproof box 1 has adhesion, and the assembled glue column 2 is fixed on the fixed adhesive plate 11.

[0035] The fixed adhesive plate 11 fixes the assembled glue column 2 on the inner wall of the fireproof box 1 through adhesion to limit the displacement of the assembled glue column 2 and prevent the assembled glue column 2 from being broken by collision with the extrusion rod 3 and the components connected thereto under external force during transportation and installation, thereby causing accidental leakage of the heat-conducting glue.

[0036] Example Four:

[0037] Based on example one:

[0038] As shown in Figure 2 , a barrier pad 10 is arranged between the piercing needle 9 and the assembled glue column 2.

[0039] The barrier pad 10 provides a protective effect for the assembled glue column 2, and the barrier pad 10 absorbs the impact force of the extrusion rod 3 by being broken or deformed, thereby avoiding the problem that the assembled glue column 2 is broken by collision with the extrusion rod 3 and the components connected thereto under external force during transportation and installation, and improving the stability of the device.

[0040] Example Five:

[0041] Based on example one:

[0042] As shown in Figure 2 , the inner wall of the fireproof box 1 in which the drainage groove 4 is arranged is provided with an inclined slope 12 inclined to the drainage groove 4.

[0043] The arrangement of the inclined slope 12 facilitates the flow of the heat-conducting glue to the interlayer between the two glasses, thereby ensuring that the heat-conducting glue can stably flow to the interlayer between the two glasses through the drainage groove after the assembled glue column 2 is pierced, and avoiding the problem that part of the glue is left in the corners of the fireproof box 1 to cause the glue to be unable to completely fill between the two glasses.

[0044] As shown in Figure 1 and Figure 3 , a groove 13 corresponding to the glass fixing groove 5 is arranged in the inner side of the U-shaped frame 6.

[0045] The U-shaped frame 6 cooperates with the glass fixing groove 5 to close the side edges of the two glasses, so that a cavity is formed between the two glasses, thereby facilitating the maintenance of the vacuum state.

[0046] The fireproof structure provided by the application can effectively maintain the vacuum state between the double-layer glasses when no fire occurs, and has good sound insulation effect through the sound transmission characteristic of the vacuum state, thereby helping to isolate external noise and effectively improving the comfort of the interior of the building.

[0047] When a fire occurs, the heat-conducting glue liquid can be released between the two glasses by pushing the extrusion rod 3, thereby significantly enhancing the heat conduction performance between the two glasses, preventing excessive thermal stress caused by the direct action of external high temperature on the glass, and thereby preventing the risk of glass breakage. When the glass breaks, the heat-conducting glue liquid can also absorb the impact force generated when the glass breaks, thereby avoiding secondary damage.

[0048] Method for use:

[0049] When no fire occurs:

[0050] The support frame 7 supports the fixed plate 8, the puncture needle 9 is away from the storage glue column 2, and the blocking pad 10 is arranged between the puncture needle 9 and the storage glue column 2, thereby preventing the fixed plate 8 from accidentally puncturing the storage glue column 2. At this time, the two glasses in the glass fixing groove 5 are in a vacuum state, and the sound insulation effect is achieved through the sound transmission characteristic of the vacuum state.

[0051] When a fire occurs:

[0052] The user presses the support frame 7, the support frame 7 pushes the fixed plate 8 to move to one side of the storage glue column 2 through the extrusion rod 3 and the fixed plate 8, punctures the blocking pad 10 and the storage glue column 2, and then, because the support frame 7 is elastic, when the support frame 7 restores to its original shape, the fixed plate 8 and the puncture needle 9 are driven to move towards the inner wall of the fireproof box 1 through the extrusion rod 3, and the heat-conducting glue liquid in the storage glue column 2 flows to between the two glasses through the liquid discharge groove 4, fills the gap between the two glasses, and acts as a heat-conducting medium between the two glasses. The heat on the glass subjected to high-temperature baking is transferred to the part with lower temperature, thereby reducing the thermal stress generated by the glass in the high temperature, and preventing the glass from breaking under high-temperature baking.
