Abstract
Description
Technical Field
[0001] This utility model relates to the field of doors and windows, specifically to a fireproof and sealing window structure. Background Technology
[0002] In the traditional field of indoor fireproofing, most measures focus primarily on fireproofing walls to prevent fire from burning through interior finishes and threatening the structural integrity and safety of occupants. However, a critical vulnerability that is often overlooked is the window area between adjacent units. Due to the lack of effective fireproofing design in this area, in the event of a fire, flames can easily spread to adjacent units through window gaps, significantly increasing the risk of fire spread and the extent of the damage. Utility Model Content

[0006] The fireproof cavity is filled with a layer of fireproof rock wool;
[0007] A galvanized steel plate is installed outside the fireproof cavity to seal it.
[0008] Furthermore, fireproof sealant is applied to the joint between the galvanized steel sheet and the fireproof cavity.
[0009] Furthermore, the column is equipped with multiple fireproof cavities.
[0010] Furthermore, galvanized steel sheets are installed between the building structure and columns, as well as between structural beams and the building structure, and are fixed with screws or bolts, the heads of which are covered with fireproof putty.
[0011] Furthermore, a rubber pad is installed between the galvanized steel sheet and the building structure, columns, and structural beams.
[0012] Furthermore, the column includes a male column and a female column. The male column has several interlayers, and the female column has a connecting strip extending into the interlayers. A rubber strip is provided between the connecting strip and the interlayer.
[0013] Beneficial effects: This application uses a composite fireproofing measure consisting of a fireproof rock wool layer and a galvanized steel plate to form a gradient flame-retardant barrier, effectively solving the problem of easy spread of fire between windows. Attached Figure Description

[0017] 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.
[0018] A fireproof and fire-resistant window structure, comprising:
[0019] Column 1 is installed between adjacent building units;
[0020] At least one side of column 1 is provided with a fireproof cavity;
[0021] The fireproof cavity is filled with a layer of fireproof rock wool 2;
[0022] A galvanized steel plate 3 is installed outside the fireproof cavity to seal it;
[0023] The support column 1, installed between adjacent building units, is a crucial supporting component of the entire fire-stopping system. The fire-resistant cavity on at least one side of the support column 1 provides space for subsequent fire-resistant measures. The fire-resistant cavity is filled with a layer of fire-resistant rock wool 2. Fire-resistant rock wool has excellent fire-resistant and heat-insulating properties, effectively preventing heat transfer and slowing the spread of fire. In the event of a fire, the fire-resistant rock wool layer 2 can quickly absorb heat, lowering the surrounding ambient temperature and buying valuable time for evacuation and fire rescue. A galvanized steel plate 3 is installed outside the fire-resistant cavity to completely seal it. The galvanized steel plate 3 not only has good strength, protecting the internal fire-resistant rock wool layer 2 from external physical damage, but also, due to its non-combustible nature, further enhances the fire resistance of the entire fire-resistant structure. The galvanized steel plate 3 and the fire-resistant cavity together constitute a composite fire-resistant measure, forming a gradient flame-retardant barrier and significantly improving the fire-stopping effect.
[0024] As a preferred embodiment, fireproof sealant 4 is provided at the joint between the galvanized steel plate 3 and the fireproof cavity. The fireproof sealant 4 can effectively fill the gaps and prevent smoke and flames from leaking from the joints, further enhancing the sealing and fireproof performance of the fireproof structure.
[0025] As a preferred embodiment, the column 1 is provided with multiple fireproof cavities 5. This design mainly utilizes the internal cavity structure to form an air barrier, thereby further improving the overall fire resistance and better resisting the attack of fire.
[0026] In a preferred embodiment, the galvanized steel sheet 3 is installed between the building structure 6 and the column 1, and between the structural beam 7 and the building structure 6, and is fixed by screws or bolts. To ensure the fire resistance of the fixing points, the heads of the screws or bolts are covered with fire-retardant putty. The fire-retardant putty effectively seals the screw holes, preventing heat and flame from spreading through the holes, thus ensuring the fire resistance integrity of the entire installation area of the galvanized steel sheet 3.
[0027] In a preferred embodiment, a rubber pad (not shown in the figure) is provided between the galvanized steel sheet 3 and the building structure 6, column 1, and structural beam 7. The rubber pad, sandwiched in between, acts as a separator, effectively preventing the galvanized steel sheet 3 from shifting due to thermal expansion and contraction, thus preventing seal failure. Specifically, this rubber pad contains a flame retardant and has a Shore hardness of 60±5. The flame retardant-containing rubber pad can delay its own combustion in the event of a fire, further enhancing its fire resistance; while the suitable Shore hardness ensures that the rubber pad maintains good elasticity and sealing properties during long-term use.
[0028] In a preferred embodiment, the support column 1 includes a male support column 101 and a female support column 102 as the mounting base for the windows on both sides; the male support column 101 is provided with several interlayers 101a, and the female support column 102 is provided with a connecting strip 102a extending into the interlayers 101a, and a rubber strip 8 is provided between the connecting strip 102a and the interlayers 101a; this unique structural design of the support column 1 not only improves the installation convenience and stability of the support column 1, but the setting of the rubber strip 8 also enhances the sealing and fire resistance of the connection of the support column 1, effectively preventing the spread of fire from the connection of the support column 1.
[0029] Specifically, the installation method in this embodiment is as follows:
[0030] Column 1 installation: Install column 1 at the interval between adjacent building units, with a fireproof cavity of 200mm width reserved on one side of column 1;
[0031] Fireproof rock wool filling: A layer of fireproof rock wool with a thickness of 2 is tightly filled into the fireproof cavity;
[0032] Galvanized steel plate 3 sealing: Galvanized steel plate 3 with a thickness of 1.5mm is used to wrap the outside of the fireproof cavity, and fireproof sealant 4 such as silicone fireproof sealant with a fire resistance limit of ≥2 hours is applied to the joints.
[0033] Fixing method: The galvanized steel plate 3 is connected to the building structure beam 6 and column 1 by screws or bolts, and the head is covered with fireproof putty with a thickness of ≥5mm;
[0034] Rubber padding layer: A rubber padding layer is added at the edge where the galvanized steel plate 3 contacts the building structure 6.
[0035] 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.
