Description

Technical Field

[0001] The utility model belongs to the technical field of fire doors and windows, and specifically relates to a smoke exhaust window for buildings. Background Art

[0002] Smoke exhaust windows for buildings are windows installed inside buildings. Their main function is to remove smoke and heat generated indoors in emergency situations such as fires to protect people's lives and reduce property losses. In the past, fires often caused serious casualties and property losses. One of the main reasons was that the thick smoke at the fire scene made it impossible for people to escape or be rescued in time. In order to improve the efficiency of fire escape and fire extinguishing, people began to pay attention to the smoke exhaust system inside buildings. Among them, smoke exhaust windows for buildings, as an important smoke exhaust channel, have become the object of much attention.

[0003] However, in actual applications, due to the limitations of the smoke exhaust window opening structure design, such as the inward opening or semi-opening style, it cannot be fully opened, which limits the smoke exhaust channel and space, resulting in unsatisfactory smoke exhaust effect. The limitations of the smoke exhaust window opening structure design make it impossible to meet the needs of rapid removal of large amounts of smoke in fire scenes. Secondly, the window size restrictions in the design of some smoke exhaust windows make it impossible to fully utilize the window space for smoke exhaust in fire emergencies, affecting the smoke exhaust effect. In addition, the design of the smoke exhaust window opening structure may have problems such as complicated operation and inconvenience in quick opening, which further affects the smoke exhaust efficiency at the fire scene.

[0004] In summary, the existing smoke exhaust windows have the problem that the smoke exhaust size is limited by the window opening, which affects the smoke exhaust effect. Utility Model Content

[0005] In view of this, the utility model provides a smoke exhaust window for a building, which can solve the problem that the smoke exhaust size of the existing smoke exhaust window is limited by the window opening, thereby affecting the smoke exhaust effect.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a smoke exhaust window for a building, which comprises a door frame and a smoke exhaust window, wherein the door frame is fixedly connected to a wall, the door frame is a rectangular structure, the smoke exhaust window is embedded in the door frame, a fireproof layer is fixedly connected to the smoke exhaust window, a flip mechanism is rotatably connected to the inner side of the door frame, the flip mechanism is rotatably connected to the smoke exhaust window through a pin shaft, the smoke exhaust window is used to exhaust smoke from the inside of the building, and the flip mechanism is used to quickly open the smoke exhaust window.

[0008] The technical effects of a smoke exhaust window for a building provided by the utility model are as follows: in emergency situations such as fire, the smoke exhaust window can quickly exhaust smoke, provide more time and space for escape, and improve the safety of the building; while exhausting smoke, it can also promote indoor ventilation, exhaust the dirty air in the room, introduce fresh air, and improve the indoor air quality. The fireproof layer can effectively prevent the fire from spreading to other parts of the building through the smoke exhaust window, thereby controlling the scope of the fire spread, reducing property losses and casualties. When the smoke exhaust window is driven to open in translation by a flip mechanism, the smoke exhaust window can be opened quickly, accelerating the speed of smoke removal and improving the efficiency of fire evacuation. The flip mechanism drives the smoke exhaust window to open in translation, so that the smoke exhaust window can be opened to a large extent, which is larger than the traditional one-way opening method. The opening space is larger and more conducive to the rapid exhaust of smoke. The translational smoke exhaust window has a large opening angle, which is convenient for repairing and cleaning the inside of the window, and convenient for maintenance personnel to maintain and manage the smoke exhaust window.

[0009] On the basis of the above technical solution, the utility model of a building smoke exhaust window can also be improved as follows:

[0010] Wherein, the flipping mechanism includes a first ring, a second ring, a third ring, a fourth ring and a support rod, the first ring and the second ring are rotationally connected to the upper top surface of the door frame, the third ring and the fourth ring are rotationally connected to the lower bottom surface of the door frame, the first ring and the third ring are symmetrically arranged, the second ring and the fourth ring are symmetrically arranged, the second ring is located at the midpoint of the upper top surface of the door frame, the fourth ring is located at the midpoint of the lower bottom surface of the door frame, the first ring is located on the left side of the second ring, and the third ring is located on the left side of the fourth ring.

[0011] Furthermore, a connecting rod is provided between the first ring and the third ring, one end of the connecting rod is fixedly connected to the first ring, and the other end of the connecting rod is fixedly connected to the third ring, the first ring is fixedly connected to one end of the first cantilever rod, and the third ring is fixedly connected to one end of the second cantilever rod.

[0012] Furthermore, the support rod includes a first support rod, a second support rod, a third support rod and a fourth support rod, one end of the first support rod is fixedly connected to the other end of the first cantilever rod, the other end of the first support rod is rotatably connected to the smoke exhaust window via a pin, one end of the third support rod is fixedly connected to the other end of the second cantilever rod, the other end of the third support rod is rotatably connected to the smoke exhaust window via a pin, one end of the second support rod is fixedly connected to the second ring, the other end of the second support rod is rotatably connected to the smoke exhaust window via a pin, one end of the fourth support rod is fixedly connected to the fourth ring, and the other end of the fourth support rod is rotatably connected to the smoke exhaust window via a pin.

[0014] Furthermore, the angle between the first cantilever rod and the first support rod is a right angle, and the angle between the second cantilever rod and the second support rod is a right angle.

[0015] Furthermore, the smoke exhaust window includes an inner layer, an outer layer and an air layer, and the air layer is arranged between the inner layer and the outer layer.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the double-layer smoke exhaust window forms an air layer between the inner and outer layers. This air layer has good thermal insulation performance, which can effectively block the influence of external cold and hot air on the indoor temperature and improve the thermal insulation performance of the building. When the double-layer smoke exhaust window is impacted from the outside, the inner window can play a certain protective role, reduce the risk of shattering, and improve the safety of the building. The double-layer smoke exhaust window has better structural strength and can resist a certain degree of external impact because the air layer between the inner and outer layers plays a role in buffering and dispersing the impact force.

[0017] Furthermore, the fireproof layer includes a fireproof board and a fireproof coating, the fireproof board is fixedly connected to the inner layer, and the fireproof coating is sprayed with the fireproof coating.

[0018] Furthermore, a gripping handle is fixedly connected to the midpoint of the connecting rod, the gripping handle is an irregular structure, the surface of the gripping handle is a rough surface, and irregular protrusions and grooves are arranged on the gripping handle.

[0019] Furthermore, a waterproof and breathable membrane is adhered to the outer layer, and a handle is fixedly connected to the inner side of the inner layer.

The fireproof layer can effectively prevent the fire from spreading to other parts of the building through the smoke exhaust window, thereby controlling the scope of the fire spread, reducing property losses and casualties. When the smoke exhaust window is driven to open in translation by a flip mechanism, the smoke exhaust window can be opened quickly, accelerating the speed of smoke removal and improving the efficiency of fire evacuation.
