Description
Technical Field
The invention relates to the technical field of fireproof doors or similar closing devices, in particular to a light and easily-installed modular fireproof heat-insulating window.
Background
5.5.32 in the building design fire Specification GB50016-2014 specifies: "residential building with a building height of more than 54 meters, each household should have a room meeting the following regulations: 1. the outer window is arranged close to the outer wall and can be opened; 2. the fire resistance limit of the inner wall body and the outer wall body is not lower than 1.00h, the door of the room is preferably a fire-proof door of class B, and the integrity of the outer window is not lower than 1.00h. "6.7.7 rule: "except for public buildings with B1-level heat insulating materials and building heights not more than 24m or residential buildings with B1-level heat insulating materials and building heights not more than 27m, the fire-resistant integrity of doors and windows on the outer walls of the buildings should not be lower than 0.50h".
Windows meeting the above requirements are fire resistant windows and fire resistant windows. Fire windows are well defined and indexed (GB 16009-2008 fire window). Fire-resistant window is not clearly defined, and the industry generally considers that the fire-resistant window is a non-heat-insulating glazing member (heat insulation refers to a position where the back surface is not burned after being burned and the heat insulation performance of the window is not an index, and is judged by heat insulation test results in the fire resistance detection of GB/T12513-2006 glazing member, and the average temperature rise amplitude of the indoor side temperature after being burned is not more than 140 ℃ and the temperature rise amplitude is not more than 180 ℃) which is arranged on the outer wall of a building and the fire resistance integrity meets the fire-proof acceptance requirements. Because fire-resistant window is compared with fire-resistant window and satisfies the index that is far less, its cost is less than fire-resistant window.
Currently, fire resistant windows are commonly known as steel fire resistant windows and non-steel fire resistant windows. The steel fire-resistant window is generally made up by referring to non-heat-insulating fire-proof window, and is composed of window frame, glass plate and connecting piece which can not be burnt out, and is very heavy, and there are a large number of thermal bridges which affect heat-insulating property of building, and its structure and appearance are completely different from other windows in building, and the adopted components are not universal with other windows in building. Instead of steel fire resistant windows typically comprise a frame and a bezel of aluminum alloy or plastic steel or a combination of both, which are not fire resistant, a steel lining is required to be provided in the frame and bezel to increase the strength after a fire, but the steel lining is ineffective after the frame and bezel are burned out, and thus a fire resistant potting compound is also required to be filled to further enhance the fire resistance, ensuring that the main body of the frame and bezel is not burned out. However, the fire-proof filling material is heavy, so that the weight-reducing advantage of the non-steel fire-proof window is lost, and meanwhile, the installation process of the window is complicated due to the large quantity of fire-proof filling material and the steel lining.
The inventors have found that the design of existing fire resistant windows presents a misleading area in either making the window frame and the bezel from fire resistant materials or protecting the window frame and the bezel from fire resistant potting compound. However, the fire-resistant window does not actually need to function when the window frame and the glass frame are not burned, and even if the window frame and the glass frame are burned by fire, the fire-resistant window can function as long as the fire and the smoke can be blocked. After all, the fire-resistant window cannot be used continuously even if the window is not damaged in the fire, so that the window is not damaged in the fire.

Detailed Description
The term "burn out" in the present invention means that the strength is completely lost after the fire is received, and the position before the fire cannot be occupied, so that a gap appears in the position occupied before the fire is received. In addition to being completely melted, burned soft and fallen or blown out holes are also noted as burned out.
As shown in fig. 1, a light and easy-to-install module type fire-resistant heat-insulating window comprises a window frame, a glass plate 2 embedded in the glass frame, a lock seat 31 and a hinge 32 arranged between the window frame and the glass frame, wherein the window frame and the glass frame are formed by splicing three layers of hollow profiles in line contact with each other, the three layers of hollow profiles are distributed from indoor to outdoor, the hollow profile positioned in the middle is marked as a connecting profile 12, and the other two layers of hollow profiles are marked as a main profile 11; the main section bar 11 of the outer layer of the glass frame extends towards the glass plate 2 and forms a folded plate wrapping the edge of the glass plate 2, and a gap is reserved between the folded plate and the glass plate 2;
the three-layer hollow section bar has two functions, namely, a space for adding various new components is reserved in the three-layer hollow section bar, and a cold bridge is broken; and the flap is for installing the fire-resistant expansion strip 7 to close the void around the glass pane 2.
The fire-resistant heat-insulating window also comprises a fire-resistant module which is additionally arranged when the fire-resistant module exists and a heat-insulating module which is additionally arranged when the heat-insulating requirement exists, and a gap for installing the fire-resistant module and the heat-insulating module is reserved in the fire-resistant heat-insulating window; the glass plate 2 is fireproof glass when fire resistance is required and is provided with an air interlayer or a vacuum interlayer when heat preservation is required, and the width of the glass embedding groove in the glass frame is not smaller than the total thickness of the glass plate 2 with the air interlayer or the vacuum interlayer.
When the common glass is adopted and no module is added, the common window is common;
when the fire-resistant module is additionally arranged and the C-type fireproof glass is used, the fire-resistant module is a fire-resistant window;
when the heat preservation module is additionally arranged and the glass with the air interlayer or the vacuum interlayer is used, the heat preservation window is formed;
when the fire-resistant module and the heat-insulating module are additionally arranged at the same time and the multi-layer C-type fireproof glass is used, the fire-resistant heat-insulating window is formed;
when the fireproof expansion strips 7 in the main section 11 of the fireproof window and the back of the clamping jaw are changed into fireproof pouring materials and composite fireproof glass is used, the fireproof window is formed; the heat preservation module is additionally arranged on the fireproof window to form the fireproof heat preservation window.
The fire-resistant module comprises a form-maintaining system made of fire-resistant profiles (profiles which do not soften/melt after being burned by a normal fire, such as steel or cermet) and for maintaining the glass pane 2 in position after both the window frame and the glass frame have been burned, and fire-resistant expansion strips 7 which act differently in different positions; the form maintenance system comprises a clamping jaw for clamping the glass plate 2; the fireproof expansion strips 7 are arranged in the main section bar 11, between the window frame and the glass frame and between the clamping jaw and the folded plate, the main section bar 11 on the outer layer is made of a material which can be burnt, the main section bar 11 is used for preventing the main section bar from falling down even if being burnt by the fireproof expansion strips 7 in the main section bar 11 before being burnt, and the fireproof expansion strips 7 in the main section bar 11, between the window frame and the glass frame and between the clamping jaw and the folded plate are connected into a whole after being burnt and the clamping jaw is pressed on the glass plate 2; the fireproof expansion strips 7 between the window frame and the glass frame are divided into three parts which are mutually separated and respectively arranged between the main profiles 11 of the outer layer, the connecting profiles 12 and the main profiles 11 of the inner layer, and the three parts of the fireproof expansion strips 7 between the window frame and the glass frame are sequentially started after being subjected to fire;
the fire-resistant expansion strip 7 is a fire-resistant strip which can expand tens times when meeting fire, thereby blocking the gap. In this embodiment, three lines of fire-protection expansion bars 7 are provided, namely fire-protection expansion bars 7 between the outer main profiles 11, fire-protection expansion bars 7 between the connecting profiles 12, and fire-protection expansion bars 7 between the inner main profiles 11. The three-layer profile is matched for use, and as the three-layer profiles are in line contact only and the fireproof expansion strips 7 are separated, the three-layer profiles and the fireproof expansion strips 7 cannot be burnt out by fire once, only one layer can be burnt out each time, and after each layer of profile is burnt out, the fireproof expansion strips 7 corresponding to the layer of profile expand to fill gaps immediately, so that the fire and the smoke are prevented from going deep, and the next layer of profile is prevented from being burnt out by flame. By using the layer-by-layer blocking mode, only one layer of components is contacted with the flame at a time to be consumed, so that all components are prevented from being contacted with the flame at one time to be consumed rapidly, and the fire-resistant time is prolonged. The test result shows that the fire and smoke can not enter the room in one hour only by the outermost layer of the fire protection line.
Note that the main section 11 of the outer layer is made of a burnable material such as aluminum alloy or plastic steel, and the shape maintaining insert core 61 is not provided inside, so that a complete cavity is left after the main section 11 of the outermost layer is burnable, and the cavity is completely filled with the fire-proof expansion strip 7, so that the fire is blocked outside and insulated. This effect is not achieved if the outer main profile 11 cannot be burnt. The fire resistant window in this example changed after the fire:
stage 1: the main profiles 11 of the outer layers are burned and softened, the fireproof expansion strips 7 of the outer layers expand, wherein the fireproof expansion strips 7 in the main profiles 11 expand and support the burned and softened main profiles 11, so that the main profiles are kept in place and are not fallen down or deformed, the fireproof expansion strips 7 between the main profiles 11 are filled with gaps, and the fireproof expansion strips 7 on the back surfaces of the clamping jaws press the clamping jaws; the fire-proof expansion strip 7 greatly delays the burning time of the outer layer main section bar 11;
stage 2: the main section bar 11 of the outer layer is burnt out, and all the fireproof expansion strips 7 of the outer layer are fused into a whole to form a porous protective layer; the process can be maintained for a very long time, the total time used by the stage 1 and the stage 2 exceeds one hour, which can meet the fire-fighting requirement, in general fire, the fire is extinguished before the stage 3 because the combustible substances burn out, and the safety margin is provided at the later stage;
stage 3: the outer fireproof expansion strips 7 are gradually consumed, the middle fireproof expansion strips 7 expand and are integrated with the heat-insulating filler 4, and the heat-insulating filler 4 is also fireproof in the embodiment, so that the process consumes more time than the stage 2;
stage 4: the middle fireproof expansion strips 7 are gradually depleted, the inner fireproof expansion strips 7 expand, the burned soft main section bars 11 are supported, and gaps among the inner main section bars 11 are filled; similar to stage 1, here the fire-resistant intumescent strip 7 greatly delays the time in which the inner main profile 11 is burned out;
stage 5: the main section bar 11 of the inner layer is burnt out, and then the fireproof expansion strip 7 of the inner layer is gradually consumed, and the process is almost as long as the period 2 is consumed;
stage 6: with the only remaining form maintaining ferrule 61, the fumes begin to enter the chamber and the fire resistant window fails, but the glass remains in place and blocks the flame.
The insulation module comprises an insulation filler 4 filled in the connecting profile 12, and a sealing tape arranged between the window frame and the glass frame. These are intended to interrupt the convection heat transfer and to achieve sealing, so that no large volume is required, the heat transfer being interrupted by the glass pane 2 and the multi-layer, heat-bridge-free profile.
As shown in fig. 2-3, the form retention system includes a form retention core 61 that is forced, a sash restraint strap 63 for securing two main profiles 11 of the sash to the form retention core 61 to prevent the main profiles 11 from yielding quickly in a fire, a glass restraint strap 64 for preventing the main profiles 11 of the glass frame from yielding quickly in a fire and clamping the glass sheet 2 after the glass frame has been burned, and a glass backing block 65 for preventing the glass sheet 2 from falling after the glass frame has been burned.
The form maintaining insert core 61 is inserted into the main section bar 11 near the indoor space and connected into a rigid frame, the rigid frame in the window frame is anchored on the wall of the door and window hole, and the hinge 32 and the lock seat 31 are made of steel and are respectively and detachably fixedly connected with the two rigid frames; this allows the two rigid frames to be joined together, ensuring that the glass pane 2 remains in place when both the window and glass frames are burned. The form-retaining insert 61 of the outer collar needs to be secured to the wall hole to ensure that the form-retaining insert 61 does not fall over after the entire window and bezel are burned out. The fixing can be chosen by the user according to the situation in question, for example by means of a connecting rod which extends through the main profile 11 to the outside.
The window frame restraining bands 63 are arranged at intervals along the periphery of the window frame and are respectively and fixedly connected with the two main profiles 11 of the window frame and the form maintaining insert core 61 in the window frame in a detachable manner; the glass restraint bands 64 are provided at intervals along the inner periphery of the glass frame, and are detachably and fixedly connected to the two main profiles 11 of the glass frame and the form-maintaining ferrule 61 in the glass frame, respectively. The combination of the window frame restraint 63 and glass restraint 64 with the fire resistant potting compound allows the window frame and glass frame to stand still even when softened, preventing subsequent components from coming into direct contact with the open fire before being completely melted, and also allows the entire window frame and glass frame to be more stable.
The clamping jaw is integrally formed with the glass restraint band 64; the purpose of the clamping jaw here is to avoid that the glass plate 2 falls down after the glass frame has been burnt, it being generally necessary to provide one clamping jaw on both the indoor side and the outdoor side of the glass plate 2. In this embodiment, the clamping jaw is arranged outside the glass plate 2 because the glass plate 2 is blocked by other refractory components at the indoor side and flame is difficult to spread into the indoor side due to layer by layer resistance.
The glass bottom block 65 is arranged at the bottom of the glass plate 2, the glass bottom block 65 is a hard block made of refractory materials which are not pulverized after being burned, and the glass bottom block 65 is in direct contact with the bottom of the glass plate 2 and is separated from the form maintaining insert core 61 by a wall plate of the main material 11. After both the window frame and the glass frame are burnt, only the lock seat 31 and the hinge 32 are left for connection between the two rigid frames, and the dead weight of the glass plate 2 is carried by the lock seat 31 and the hinge 32 which are possibly burnt by fire, so that the glass supporting bottom block 65 is required to be arranged below. The glass backing block 65 must be hard and not sintered (the refractory fiber mat may be sintered after being burned, such as rock wool) to avoid bursting of the glass by falling into contact with the metal.
The connecting section bars 12 are plates with the plate surfaces perpendicular to the wall where the fire-resistant heat-insulating window is located, each connecting section bar 12 comprises two plates, two sides of each plate are expanded and respectively inserted into the two main section bars 11, the heat-insulating filler 4 is flame-retardant modified polyurethane sponge filled between the two plates, gaps are reserved or heat-insulating materials are filled at the positions, inserted into the main section bars 11, of the plates, and gaps are reserved or heat-insulating materials are filled between the window frame restraining bands 63 and the glass restraining bands 64 and the main section bars 11. The sheet material in this embodiment is a plastic profile of low thermal conductivity such as PA66 nylon insulating strips, which does not form a cold bridge. However, if a high thermal conductivity profile such as an aluminum alloy is selected, the plate is inserted into the main profile 11 with a certain gap or with some insulation material to avoid cold bridge formation. Similarly, the window frame restraining strip 63 and the glass restraining strip 64 are also spaced from the main profile 11 or are lined with some thermal insulation material.
A gap for installing a sealing belt and a fireproof expansion strip 7 is reserved between the window frame and the glass frame; the main profile 11 has protrusions extending towards the walls of the window opening for forming a void for the installation of the window frame restraining strip 63; padding is filled between the glass frame and the glass plate 2; the spacer is provided to ensure a gap between the glass frame and the glass plate 2, to ensure a space for mounting the glass restraint belt 64 and the glass retainer block 65 when required, and to smoothly mount the glass thinner than the composite fire-resistant glass when selected. Among the padding between the glass frame and the glass plate 2, the padding located on one periphery of the side face of the glass plate 2 is a rock wool block doped with fireproof expansion strips 7, and the rest positions are fireproof cotton fiber strips. These gaskets, while not replacing the glass backing block 65, do not burn at least to exacerbate the fire and at the same time stabilize the glass sheet 2 over time. The rock wool block with the fire-resistant expansion strips 7 incorporated therein can further grip the glass pane 2 after a fire.
The form maintaining insert 61 is connected into a rigid frame through an insert connecting angle code 62, the insert connecting angle code 62 is respectively arranged at the inner angle position of the mosaic frame and the outer angle position of the window frame, and the insert connecting angle code 62 is detachably and fixedly connected with two main profiles 11 of the mosaic frame and is detachably and fixedly connected with two main profiles 11 of the window frame. The ferrule connecting angle 62 not only maintains the ferrule 61 in the connected configuration, but also functions like a window frame restraint band 63 and a glass restraint band 64.
The cross section of the form maintaining insert core 61 is U-shaped with an opening facing the outside, and the form maintaining insert core 61 is internally provided with a fireproof expansion strip 7. The shape maintenance insert 61 does not block the front of the fire-protection expansion strip 7, but allows the fire-protection expansion strip 7 to directly face open fire, thereby exerting the due function, and also allows the final line of protection of the shape maintenance insert 61 to contact open fire later.
The sealing tape comprises a main sealing tape 51 which is respectively arranged on the connecting section bar 12 of the window frame and the connecting section bar 12 of the glass frame and is meshed with each other, and a self-tightening sealing tape 52 which is arranged between the main section bar 11 of the window frame and the main section bar 11 of the glass frame and is fixed on one main section bar 11; two main profiles 11 adjacent to each other and respectively positioned in the window frame and the glass frame extend in opposite directions to form an air flow channel parallel to the wall where the fire-resistant heat-insulating window is positioned, the self-tightening sealing tape 52 is a tongue-and-groove adhesive tape arranged in the air flow channel, and when the fire-resistant heat-insulating window is an inward opening window, the tongue-and-groove adhesive tape is provided with a blocking tape for blocking the tongue-and-groove adhesive tape to form a seal before being driven by air flow entering the room to bend; when the fire-resistant heat-insulating window is an outward-opening window, the tongue-and-groove adhesive tape is provided with a blocking tape for blocking the tongue-and-groove adhesive tape to form a seal before being driven to bend by air flow entering the outdoor.
The self-sealing strip 52 herein provides enhanced sealing at both the location of the self-sealing strip, whether it is at ambient or outdoor pressure. The window in this embodiment is the inwardly opened window, and when indoor atmospheric pressure is big, the tight pressure of glass frame makes sealed effect by reinforcing on the window frame, and when outdoor atmospheric pressure is big, the air current between glass frame and the window frame makes the tongue-and-groove adhesive tape press on the fender area, makes sealed effect by reinforcing.
The main seal belt 51 is a pair of equal pressure rubber strips which are mutually overlapped, and the overlapped surface of the equal pressure rubber strips is provided with a protrusion for enhancing the sealing effect.
The heat-insulating filler 4 is arranged coplanar with the cavity in the glass plate 2, so that heat loss is reduced.
The main section bar 11 is made of aluminum alloy, the connecting section bar 12 is made of nylon, and all the parts in the form maintaining system are made of stainless steel.
