Description

Technical Field

[0001] This utility model relates to the field of glass door technology, specifically a curtain wall glass door. Background Technology

[0002] In modern building curtain wall systems, glass doors are widely used in commercial complexes, transportation hubs, and high-end office buildings due to their advantages such as transparency, aesthetics, and strong spatial integration. However, existing glass doors have significant defects in sealing, insulation, and fire resistance: conventional rubber sealing strips are often used between the door frame and the glass, which are prone to aging and deformation over long-term use, leading to a decrease in airtightness and watertightness, increased heat exchange, and increased building energy consumption. Furthermore, in the event of a fire, the sealing structure at the door gaps lacks sufficient heat resistance and fails rapidly at high temperatures, allowing flames and toxic fumes to easily leak out, not only accelerating the spread of fire but also seriously threatening the safety of personnel evacuation. Therefore, we need to propose a new type of curtain wall glass door. Utility Model Content

[0003] The purpose of this utility model is to provide a curtain wall glass door to solve the problems mentioned in the background art, such as poor sealing and heat insulation between the door frame and the glass, and the easy leakage of flames and toxic fumes from the gaps during a fire.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A curtain wall glass door includes: a mounting frame, and two sets of door panels movably connected to the mounting frame via door hinges; a fireproof mechanism installed on the top, bottom, and sides of the two sets of door panels for sealing the gaps between the door panels and the mounting frame, the gaps between the two sets of door panels, and the gaps between the bottom of the door panels and the ground; and protective glass installed on the door panels.

[0006] The fireproof mechanism includes a mounting shell, a first expanded graphite fireproof strip, and a second expanded graphite fireproof strip. The first expanded graphite fireproof strip is fixedly installed inside the mounting shell.

The mounting shell is fixedly installed inside the first mounting groove. The top, bottom, and sides of the door panel are each provided with two sets of second mounting grooves. The first mounting groove is located between the two sets of second mounting grooves. The second expanded graphite fireproof strip is installed inside the second mounting groove.

[0007] Preferably, a locking block for positioning the second expanded graphite fireproof strip is fixedly connected to the door panel, and the side of the second expanded graphite fireproof strip contacts the locking block.

[0008] Preferably, the top, bottom and sides of the door panel are provided with two sets of inclined portions.

[0009] Preferably, the protective glass includes a first fireproof glass, a second fireproof glass, an interlayer, and a Low-E film. The interlayer is disposed between the first fireproof glass and the second fireproof glass, and is fixedly connected to the first fireproof glass and the second fireproof glass. The first fireproof glass and the second fireproof glass are connected and fixed through the interlayer. A hollow cavity is left between the first fireproof glass and the second fireproof glass. The Low-E film is coated on the inner side of the first fireproof glass and the second fireproof glass facing the hollow cavity.

[0010] Preferably, the system further includes a positioning mechanism, which comprises a positioning frame, sealant, pressure strip, and rubber frame.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution:

[0022] A curtain wall glass door includes: a mounting frame 8, and two sets of door panels 1 movably connected to the mounting frame 8 via door hinges 5; a fireproof mechanism 3 installed on the top, bottom and sides of the two sets of door panels 1, for sealing the gaps between the door panels 1 and the mounting frame 8, the gaps between the two sets of door panels 1, and the gaps between the bottom of the door panels 1 and the ground; and protective glass 2 installed on the door panels 1.

[0023] It should be noted that the mounting frame 8 is made of 6063-T5 high-strength aluminum alloy profile, which is anodized and has excellent corrosion resistance and anti-aging properties. It can be adapted to the structural dimensions of different building curtain walls. During installation, it is fixed to the building concrete structure with M12 stainless steel expansion bolts to ensure the stability of the frame.

[0024] Door panel 1 uses a hollow aluminum alloy frame, with flame-retardant insulation cotton filled inside the frame, which reduces the weight of the door and improves its insulation performance.

[0025] In an optional embodiment: such as Figure 5As shown, the fireproof mechanism 3 includes a mounting shell 301, a first expanded graphite fireproof strip 302, and a second expanded graphite fireproof strip 303. The first expanded graphite fireproof strip 302 is fixedly installed inside the mounting shell 301. The top, bottom, and sides of the door panel 1 are all provided with first mounting grooves 304 that are adapted to the mounting shell 301. The mounting shell 301 is fixedly installed inside the first mounting grooves 304. The top, bottom, and sides of the door panel 1 are all provided with two sets of second mounting grooves 305. The first mounting grooves 304 are located between the two sets of second mounting grooves 305. The second expanded graphite fireproof strip 303 is installed inside the second mounting grooves 305.

[0026] It should be noted that the first expanded graphite fireproof strip 302 on one side of door panel 1 contacts the inner side of the mounting frame 8, the first expanded graphite fireproof strip 302 on the other side of door panel 1 contacts the first expanded graphite fireproof strip 302 on the side of another set of door panels 1, the first expanded graphite fireproof strip 302 at the top of door panel 1 contacts the inner top of the mounting frame 8, and the first expanded graphite fireproof strip 302 at the bottom of door panel 1 contacts the ground. The first expanded graphite fireproof strip 302 can seal the gaps between the mounting frame 8, the two sets of door panels 1, and the ground, thus preventing the leakage of internal building temperature.

[0027] Furthermore, in the event of a fire, when the flame temperature reaches 300℃ or higher, the first expanded graphite fireproof strip 302 and the second expanded graphite fireproof strip 303 will expand 200-300 times in volume, forming a loose and porous expanded carbon layer (density 0.3-0.5g / cm³), which tightly seals all gaps between the door panel 1 and the mounting frame 8, the two sets of door panels 1, and the door panel 1 and the ground (the maximum gap filling thickness can reach 50mm), effectively blocking the penetration of flames and the leakage of toxic fumes (such as CO and NO2), preventing the spread of fire, and buying time for personnel evacuation.

[0028] After the flame burns the first expanded graphite fireproof strip 302 and the second expanded graphite fireproof strip 303, the loose expanded carbon layer formed by the first expanded graphite fireproof strip 302 and the second expanded graphite fireproof strip 303 can block the gaps, prevent the flames and toxic fumes from leaking out of the gaps, and prevent the fire from spreading.

[0029] In an optional embodiment: such as Figure 5 As shown, a locking block 306 for positioning the second expanded graphite fireproof strip 303 is fixedly connected to the door panel 1, and the side of the second expanded graphite fireproof strip 303 contacts the locking block 306.

[0030] It should be noted that the second expanded graphite fireproof strip 303 can be positioned by the locking block 306, so as to fix the second expanded graphite fireproof strip 303 after installation.

[0031] In an optional embodiment: such as Figure 5As shown, the top, bottom and sides of the door panel 1 are provided with two sets of inclined parts 307.

[0032] It should be noted that in the event of a fire, the flames can quickly contact the second expanded graphite fireproof strip 303 along the inclined surface, shortening the thermal response time of the fireproof strip; at the same time, the inclined part can guide the expanded carbon layer to accumulate towards the gap, improving the sealing efficiency.

[0033] In an optional embodiment: such as Figure 5 As shown, the protective glass 2 includes a first fireproof glass 201, a second fireproof glass 202, an interlayer 203, and a Low-E film 204. The interlayer 203 is disposed between the first fireproof glass 201 and the second fireproof glass 202, and the interlayer 203 is fixedly connected to the first fireproof glass 201 and the second fireproof glass 202. The first fireproof glass 201 and the second fireproof glass 202 are connected and fixed through the interlayer 203. A hollow cavity is left between the first fireproof glass 201 and the second fireproof glass 202. The Low-E film 204 is coated on the inner side of the first fireproof glass 201 and the second fireproof glass 202 facing the hollow cavity.

[0034] It should be noted that the 203 interlayer contains nano-cerium oxide ultraviolet absorbers, which can block more than 90% of ultraviolet rays with wavelengths of 300-400nm, preventing indoor furniture and decorations from fading due to ultraviolet radiation.

[0035] The hollow cavity is filled with argon gas (an inert gas) with a purity of over 90%, which can reduce the heat transfer coefficient K value of the door to ≤1.8W / (㎡・K) and improve the thermal insulation performance; at the same time, argon gas has a better sound insulation effect than air, making the sound insulation of the door ≥35dB;

[0036] Low-E 204 film can reflect more than 70% of far-infrared rays, further reducing indoor and outdoor heat exchange, providing significant heat preservation in winter and heat insulation in summer, without affecting the transparency of the glass.

[0037] In an optional embodiment: such as Figure 5 As shown, it also includes a positioning mechanism 4, which includes a positioning frame 401, sealant 403, pressure strip 404, and rubber frame 405. A positioning groove 402 is provided in the door panel 1, the positioning frame 401 is installed in the positioning groove 402, and a placement groove is provided in the positioning frame 401. The rubber frame 405 is installed in the placement groove. The surfaces of the first fireproof glass 201 and the second fireproof glass 202 are in contact with the inner side of the rubber frame 405. The pressure strip 404 is provided in the placement groove and is pressed against the first fireproof glass 201 and the second fireproof glass 202. The sealant 403 is fixedly connected to the first fireproof glass 201, the second fireproof glass 202, and the pressure strip 404.

[0038] It should be noted that the sealant 403 acts as a buffer (reducing the impact of door opening and closing vibrations on the glass and lowering the risk of breakage), and also initially seals the gap between the glass and the positioning frame; the pressure strip 404 can evenly press the first fireproof glass 201 and the second fireproof glass 202 together; applying the sealant evenly to the joint between the glass and the pressure strip can effectively block rainwater and air penetration, while also having a certain degree of elasticity to adapt to thermal expansion and contraction caused by temperature changes.

[0039] In an optional embodiment: such as Figures 1 to 3 As shown, it also includes a door lock 6 fixedly installed at the bottom of the door panel 1, with the door lock 6 precisely aligned with the preset lock hole on the ground.

[0040] It should be noted that the glass door is fixed by the door lock 6, and handles 7 are fixedly installed on both sides of the two sets of door panels 1. The door panels 1 can be opened by pushing or pulling the handles 7.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
