Detailed Description
The term "burn out" in the present utility model 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, an additional installation kit for enhancing the fire resistance of a bridge-cut-off aluminum window, wherein the bridge-cut-off aluminum window comprises a window frame, a glass plate 1 embedded in the glass frame, a lock seat 21 and a hinge 22 arranged between the window frame and the glass frame, wherein the window frame and the glass frame are formed by splicing three layers of profiles which are in line contact with each other, the three layers of profiles are distributed from indoor to outdoor, the profile positioned in the middle is marked as a connecting profile, and the other two layers of profiles are marked as main profiles; the main section bar is a hollow section bar, and the glass plate 1 is fireproof glass;
the retrofit kit includes a form-maintaining system made of refractory 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 1 in place after both the window frame and the glass frame are burned, a fire-proof potting compound 4 filled in the main profiles and for extending the time required for the window frame and the glass frame to be burned and preventing heat transfer into the room, and a fire-proof expansion strip 5 layered between the window frame and the glass frame and for filling the void left after both the window frame and the glass frame are burned.
The fireproof filling material 4 refers to a filler which has a heat insulation effect and can absorb a large amount of heat, can keep the main profile from yielding or melting in a short time, and has the effect of caulking and sealing. The fireproof expansion strip 5 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 consisting of fire protection expansion bars 5 are provided, namely fire protection expansion bars 5 between the outer main profiles, fire protection expansion bars 5 between the connecting profiles, and fire protection expansion bars 5 between the inner main profiles. The three-layer profile is matched for use, and as the three-layer profiles are in line contact only and the fireproof expansion strips 5 are separated, the three-layer profiles and the fireproof expansion strips 5 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 5 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 cannot enter the room in one hour and one side of the room is not scalded by only the outermost layer of the fire protection line. In this embodiment, the window frame and the glass frame are not used to block fire, and the glass plate 1 is further provided with a fixing system which is still connected with the wall hole when the window frame and the glass frame are not present, so that after the window frame and the glass frame are burnt, the glass can still be ensured to be maintained in situ, and all the holes are filled.
As shown in fig. 1-3, the form retention system includes a form retention core 31 that is forced, a sash restraint strap 33 for securing two main profiles of the sash to the form retention core 31 to prevent the main profiles from yielding quickly in a fire, a glass restraint strap 34 for preventing the main profiles of the glass frame from yielding quickly in a fire and clamping the glass sheet 1 after the glass frame has been burned, and a glass backing block 35 for preventing the glass sheet 1 from falling after the glass frame has been burned.
The form maintaining insert core 31 is inserted into the main section bar near the room and connected into a rigid frame, and the hinge 22 and the lock seat 21 are both made of steel (fire-resistant) 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 1 remains in place when both the window and glass frames are burned. The form-retaining insert 31 of the outer ring needs to be fixed to the wall hole to ensure that the form-retaining insert 31 does not fall over after the entire window and bezel are burned out. The fixing can be selected according to the situation of the site, for example, a connecting rod penetrating the main section bar and extending to the outside can be used for fixing.
The window frame restraining bands 33 are arranged at intervals along the periphery of the window frame and are respectively and detachably fixedly connected with the two main sections of the window frame and the form maintaining insert core 31 in the window frame; the glass restraint bands 34 are arranged at intervals along the inner periphery of the glass frame and are respectively and fixedly connected with the two main profiles of the glass frame and the form maintaining insert core 31 in the glass frame in a detachable manner; the combination of the window frame restraint strip 33 and the glass restraint strip 34 with the fire resistant potting compound 4 allows the window frame and the glass frame to stand still even when they are softened, prevents subsequent components from coming into direct contact with an open fire before they are completely melted, and also allows the entire window frame and glass frame to be more stable.
The glass restraint belt 34 is also provided with clamping jaws which are integrally formed with the glass restraint belt 34 and are used for clamping the glass sheet 1; the purpose of the clamping jaw here is to avoid that the glass plate 1 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 1. In this embodiment, the clamping jaw is arranged on the outer side of the glass plate 1 because other refractory components are blocked in the inner side of the glass plate 1 and flame is difficult to spread into the chamber due to layer by layer blocking.
The glass support bottom block 35 is arranged at the bottom of the glass plate 1, the glass support bottom block 35 is a hard block made of refractory materials which are not pulverized after being burned, and the glass support bottom block 35 is in direct contact with the bottom of the glass plate 1 and is separated from the form maintaining insert core 31 by a wall plate of one layer of main materials. After both the window frame and the glass frame are burnt, the connection between the two rigid frames only leaves the lock seat 21 and the hinge 22, and the dead weight of the glass plate 1 is carried by the lock seat 21 and the hinge 22 which are possibly burnt by fire, so that the glass supporting bottom block 35 needs to be arranged below. The glass backing block 35 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.
A gap for installing a sealing belt and a fireproof expansion strip 5 is reserved between the window frame and the glass frame; the main profile is provided with a protuberance which extends to the wall of the window opening and is used for forming a reserved gap for installing the window frame restraining belt 33; padding is filled between the glass frame and the glass plate 1; the spacer is provided to ensure a gap between the glass frame and the glass plate 1, and to ensure a space for mounting when the glass restraint belt 34 and the glass block 35 are required, and to enable smooth mounting even when glass thinner than fire-proof glass is selected to be mounted.
The padding material positioned on the periphery of the side face of the glass plate 1 is rock wool blocks, and the rest positions are fire-resistant cotton fiber strips. These gaskets, although not replacing the glass backing block 35, do not burn at least to exacerbate the fire and at the same time stabilize the glass sheet 1 over time.
The form maintaining insert core 31 is connected into a rigid frame through an insert core connecting angle code 32, the insert core connecting angle code 32 is respectively arranged at the inner angle position of the mosaic frame and the outer angle position of the window frame, and the insert core connecting angle code 32 is detachably and fixedly connected with two main profiles of the mosaic frame and the two main profiles of the window frame.
The cross section of the form maintaining insert core 31 is U-shaped with an opening facing the outside, and the form maintaining insert core 31 is filled with fireproof filling material 4. The form-retaining insert 31 does not block the fire-protecting potting compound 4 but allows the fire-protecting potting compound 4 to open a fire on a straight face, thereby allowing it to function as it were, and also allows the final line of protection of the form-retaining insert 31 to be later in contact with the open fire.
The main section bar of the outer layer of the glass frame extends towards the glass plate 1 and forms an extra cavity which wraps the edge of the glass plate 1, and the extra cavity is filled with fireproof filling material 4. The extra cavity is to seal off the void around the glass plate 1.
In the embodiment, the connecting section bar comprises two plates, wherein two sides of the plates are expanded and respectively inserted into the two main section bars, and flame-retardant modified polyurethane sponge is filled between the two plates; the main section bar is made of aluminum alloy, the connecting section bar is made of nylon, and all the parts in the form maintaining system are made of stainless steel.
The above examples are only illustrative of the preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model, and various modifications and improvements made by those skilled in the art to the technical solution of the present utility model should fall within the scope of protection defined by the claims of the present utility model without departing from the spirit of the present utility model.
