Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a fire-resistant window and firewall. Background Technology

[0002] Fire-resistant windows, also known as fireproof windows, are windows whose connecting frames can meet the requirements for fire resistance stability and fire resistance integrity for a certain period of time. They must also meet requirements for lighting, heat insulation, sun shading, and sound insulation.

[0003] Existing fire-fighting windows, such as the fire rescue window curtain wall system disclosed in patent publication number CN114809390A, include irregularly shaped exterior panels, upper aluminum alloy subframes, and lower aluminum alloy subframes, with tempered glass embedded in the upper and lower aluminum alloy subframes. These systems use single-pane tempered glass, which is susceptible to fire resistance degradation or failure due to edge impacts, breakage, or surface scratches, exhibiting a degree of uncertainty and failing to effectively block radiant heat from flames. Utility Model Content

[0004] The purpose of this invention is to provide a fire-resistant window and firewall that can improve the fire resistance of the fire-resistant window.

[0005] The technical solution of this utility model is: a fire-resistant window, comprising tempered glass, fireproof glass, a ring-shaped PC outer frame formed by concrete casting, a first end seat embedded in the ring-shaped PC outer frame for installing the fireproof glass, and a second end seat embedded in the ring-shaped PC outer frame for installing the tempered glass.

[0006] Preferably, the first end seat includes an outer frame, an inner frame, a fireproof plate, and a reinforcing plate. One side of the outer frame is a first closed end, and the other side of the outer frame is a first open end. One side of the inner frame is a second closed end, and the other side of the inner frame is a second open end. The inner frame is placed inside the outer frame. The first open end and the second open end are located on the same side and communicate with each other. The periphery of the fireproof glass is embedded in the first open end and the second open end. The second closed end, the reinforcing plate, and the first closed end are sequentially attached from the inside to the outside and connected to the PC outer frame by expansion bolts. Fireproof plates are provided between the outer frame and the inner frame, and inside the inner frame.

[0007] Preferably, the outer surface of the outer frame is provided with a thermal insulation mortar layer, the thermal insulation mortar layer is bonded to the PC outer frame, and the expansion bolts connect the thermal insulation mortar layer.

[0008] Preferably, the second end seat includes a first frame and a second frame located inside the first frame, the first frame being connected to the PC outer frame, and the periphery of the tempered glass being embedded in the second frame.

[0009] Preferably, the PC outer frame is provided with a U-shaped ring, and the first frame is connected to the U-shaped ring by fasteners.

[0010] Preferably, both the first frame and the second frame are provided with sound insulation cotton.

[0011] Preferably, the installation gap between the fireproof glass and the first end seat is filled with sealant, and the second end seat is provided with a sealing strip that adheres to the tempered glass.

[0012] Preferably, a waterproof and vapor barrier membrane is provided between the first end seat and the second end seat, and the waterproof and vapor barrier membrane is located close to the PC outer frame.

[0015] Compared with related technologies, the beneficial effects of this utility model are as follows: I. The fire-fighting window of this utility model adopts a PC frame made of cast concrete and is fitted with fireproof glass and tempered glass. PC concrete has fireproof properties, which greatly improves the fire resistance and fire resistance of the fire-fighting window. In addition, the various parts of the fire-fighting window are connected as one unit by the PC frame, which facilitates transportation and avoids damage during transportation. II. The fire-fighting window of this utility model adopts a structure that combines fire-resistant glass and tempered glass. Each of them can give full play to its advantages in performance and can effectively block the radiant heat of flames. This effectively solves the problem that the fire resistance performance of the fire-fighting window will decrease after the single-layer tempered glass is broken. Third, the first end seat of the fireproof glass in this utility model is filled with a fireproof board, which makes the fire resistance integrity ≥3 hours, and can be used in large-area street-facing firewalls. Fourth, the second end seat for installing the steel protective glass in this utility model is filled with sound insulation cotton, which greatly improves the sound insulation effect of the fire window; Fifth, the fire-resistant window firewall of this utility model improves indoor lighting and beautifies the building facade.
