Description

Technical Field

[0001] This utility model relates to the field of fireproof door and window technology, specifically to a fireproof door and window sealing structure that is easy to assemble. Background Technology

[0002] The fire-resistant expansion strips used in fire doors and windows are prone to aging and cracking after long-term use due to environmental temperature and humidity, ultraviolet radiation and daily friction, resulting in a decline in sealing performance. They need to be replaced regularly to maintain the fire-resistant effect.

[0003] In existing sealing structures, fire-resistant expansion strips are mostly fixed to door and window frames by strong adhesive or welding. Replacement requires the use of professional tools to remove residual adhesive or disassemble metal fasteners, which is not only cumbersome and time-consuming, but also easily causes scratches, deformation and other damage to the door and window frame itself. Although some split sealing structures can be replaced in sections, they require precise matching of the original size and installation hole positions. The replacement process still requires professional operation, making it difficult to complete maintenance quickly. Especially in shopping malls, where maintenance efficiency is required, the inconvenience of replacing traditional fire-resistant expansion strips increases maintenance costs and may also leave fire safety hazards due to excessively long replacement cycles. Therefore, we need to provide a fireproof door and window sealing structure that is easy to assemble. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a fireproof door and window sealing structure that is easy to assemble, comprising:

[0025] Door frame 100, which includes an outer frame 110 and a flame-retardant frame 120 connected to the outer frame 110;

[0026] Window frame 200, which includes an inner frame 210 and a flame-retardant mechanism 220 installed on one side of the inner frame 210. One side of the inner frame 210 is hinged to the outer frame 110 via a hinge.

[0027] The flame-retardant mechanism 220 includes a slide groove 222 and a slide bar 221 that is slidably installed in the slide groove 222. The inner frame 210 is provided with mounting parts 300 at each of the four corners. The mounting parts 300 are used to fix the slide bar 221 in the slide groove 222.

[0028] Specifically, a flame-retardant mechanism 220 is installed on one side of the inner frame 210 to seal and block smoke, and facilitates the replacement of the fire-resistant expansion-type abutment strip 221c. The flame-retardant mechanism 220 integrates the sliding groove 222 and the fire-resistant expansion-type abutment strip 221c, and is directly installed on one side of the inner frame 210. It can precisely align with the adhesive layer frame 6 of the door frame 100, and the groove 5 of the abutment strip 221c matches the protrusion 7 of the adhesive layer frame 6 to form a double sealing structure, which can effectively block the smoke penetration at the gaps. When exposed to fire, the abutment strip 221c expands rapidly, which can further fill any gaps that may be generated, preventing flames and high-temperature smoke from spreading through the gaps in the doors and windows.

[0029] The frame is fixed by the mounting parts 300 at the four corners of the inner frame 210. When replacing, there is no need to disassemble the entire door and window structure. Simply loosen the bolts 8 on the limiting corner seat 320 and remove the corner seat. Then, the abutment strip 221c in the slide groove 222 can be pulled out directly. After replacing the new strip, the limiting corner seat 320 is re-clamped and the bolts 8 are tightened to complete the operation. This greatly reduces maintenance costs and replacement time and avoids safety hazards caused by long replacement cycles.

[0030] The slider 221 includes a middle strip 221a, a limiting strip 221b and an abutting strip 221c. The middle strip 221a is located between the limiting strip 221b and the abutting strip 221c, and the abutting strip 221c extends to the outside of the inner frame 210.

[0031] Furthermore, in the slider 221, the middle strip 221a and the limiting strip 221b adopt an integral molding structure, and the two together form a T-shaped structure; the abutment strip 221c is fixedly connected to the side of the middle strip 221a away from the limiting strip 221b by adhesive bonding, and the abutment strip 221c is made of fire-resistant expanding material, and its side away from the middle strip 221a extends to the outside of the inner frame 210 and corresponds to the adhesive layer frame 6; the T-shaped middle strip 221a and the limiting strip 221b can be adapted and engaged with the T-shaped limiting groove 4 in the slide groove 222, which not only realizes the stable sliding of the slider 221 in the slide groove 222, but also prevents the slider 221 from falling out of the slide groove 222.

[0032] A limiting groove 4 is provided in the sliding groove 222 for the sliding of the limiting strip 221b;

[0033] Specifically, the slide groove 222 and the inner frame 210 are manufactured using an integral molding process. The groove wall of the limiting groove 4 is made of high-temperature resistant metal material, and its inner wall surface is smoothed. When the slide bar 221 slides in the slide groove 222, the limiting bar 221b slides along the inner wall of the limiting groove 4. The smooth groove wall can reduce the frictional resistance between the limiting bar 221b and the limiting groove 4, making it easy for the slide bar 221 to be quickly installed and disassembled. At the same time, the limiting groove 4 made of high-temperature resistant metal material can maintain structural stability in high-temperature environments and avoid limiting failure due to high-temperature deformation.

[0034] A groove 5 is provided on one side of the contact strip 221c, and the contact strip 221c is set as a fireproof expansion strip;

[0035] It should be noted that the groove 5 on the side of the contact strip 221c away from the middle strip 221a faces the protrusion 7 of the adhesive frame 6; the fire-resistant expansion material of the contact strip 221c is an expandable graphite-based composite material, which can expand rapidly when exposed to high temperature and open flame, and its volume can increase significantly after expansion; under normal conditions, the groove 5 can precisely align with the protrusion 7 of the adhesive frame 6 to form a preliminary seal; when exposed to fire, the contact strip 221c expands, filling the tiny pores between the groove 5 and the protrusion 7, significantly improving the fire and smoke blocking performance.

[0036] A glue layer frame 6 is fixedly installed on the surface of the flame-retardant frame 120 near the inner frame 210. The surface of the glue layer frame 6 is provided with a protrusion 7 that matches the groove 5.

[0037] It is worth noting that the adhesive layer frame 6 is made of elastic flame-retardant rubber material, which is fixedly connected to the side of the flame-retardant frame 120 near the inner frame 210 through an injection molding process; the protrusion 7 on the surface of the adhesive layer frame 6 is an integrally molded structure with the adhesive layer frame 6, and the cross-sectional shape of the protrusion 7 is adapted to the cross-sectional shape of the groove 5 of the contact strip 221c; when the outer frame 110 and the inner frame 210 are closed, the protrusion 7 is embedded in the groove 5 and is squeezed against the inner wall of the groove 5, and the elastic flame-retardant rubber material of the adhesive layer frame 6 will deform, filling the gap between the protrusion 7 and the groove 5 to achieve double sealing; at the same time, the elastic material can buffer the impact force when the door and window are closed.

[0038] Mounting component 300 includes a slot 310 and a limiting angle seat 320. The inner frame 210 has slots 310 at all four corners. The limiting angle seat 320 is engaged in the slot 310. The limiting angle seat 320 is slidably installed in the limiting angle seat 320. The inner frame 210 has holes 9 on its surface for threaded installation of the bolts 8.

[0039] Furthermore, the mounting component 300 has an L-shaped slot 310, which is integrally formed with the inner frame 210. The inner wall of the slot 310 is roughened. The limiting angle seat 320 is made of wear-resistant metal material, and its shape matches the L-shaped slot 310. The inner wall of the limiting angle seat 320 has a sliding hole that matches the bolt 8. The bolt 8 is threadedly connected to the hole 9 on the surface of the inner frame 210. During installation, the limiting angle seat... The corner bracket 320 is inserted into the slot 310. The rough inner wall of the slot 310 increases the friction between the corner bracket 320 and the slot 310, preventing the corner bracket 320 from loosening. The bolt 8 passes through the sliding hole of the corner bracket 320 and connects to the hole 9 of the inner frame 210, which can fix the corner bracket 320 in the slot 310, thereby limiting the slider 221. When disassembling, the corner bracket 320 can be removed from the slot 310 by loosening the bolt 8.

[0040] The card slot 310 is L-shaped and is compatible with the limiting angle seat 320;

[0041] The lengths of the two right-angled sides of the L-shaped slot 310 are matched with the lengths of the two right-angled sides of the limiting angle seat 320. The depth of the slot 310 is greater than the thickness of the limiting angle seat 320. The sliding hole of the limiting angle seat 320 is a through hole with a diameter slightly larger than the diameter of the bolt 8, so that the bolt 8 can slide smoothly in the sliding hole.

[0042] All threaded mounting surfaces in this application utilize a modified triangular thread with a self-locking function. The thread helix angle is designed to be 1.5°-2.5° to enhance the anti-loosening effect. After phosphating, the thread surface is coated with an 8-12μm Dacromet coating and impregnated with silicone sealant to form a sealing layer, resulting in excellent corrosion resistance. In addition, the thread can effectively expel dust, and it can still be used normally even if a small amount of dust adheres to it.

[0043] This device features an outer frame 110 hinged to an inner frame 210. One side of the outer frame 110 has a rectangular groove, and a flame-retardant frame 120 is fixed to this rectangular groove on one side of the outer frame 110 by bolts 8. A frame-shaped adhesive layer 6 is integrally molded on one side of the flame-retardant frame 120. The protruding strips 7 on the surface of the adhesive layer 6 are adapted to the grooves 5 on the surface of the contact strip 221c. The adhesive layer 6 has a deformation effect; when the protruding strips 7 and grooves 5 are pressed together, it has the ability to deform and fill the gaps. The contact strip 221c is a fire-resistant expansion strip that can expand upon contact with a high-temperature open flame, filling the space between the outer frame 110 and the inner frame 210, thus providing fire and smoke resistance. The inner frame 210 contains high-temperature resistant tempered glass. When the contact strip 221c needs to be replaced... First, rotate bolt 8 to separate bolt 8 from hole 9, which can separate the limiting angle seat 320 from the slot 310. After removing the limiting angle seats 320 at all four corners of the inner frame 210, pull the slide bar 221 out of the slide groove 222 to replace the slide bar 221. The slide bar 221 includes a middle strip 221a, a limiting strip 221b, and an abutting strip 221c. The middle strip 221a is located between the limiting strip 221b and the abutting strip 221c. The abutting strip 221c is an expansion strip that is attached to the adhesive layer frame 6. The limiting strip 221b and the middle strip 221a are integrally formed into a T-shape, and the limiting groove 4 and the slide groove 222 are integrally formed into a T-shape. The two fit together to prevent the slide bar 221 from falling off, making it easy to replace the slide bar 221.

[0044] 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.
