Description

Technical Field

[0001] The utility model relates to the technical field of fireproof steel doors, in particular to a green building energy-saving and fireproof steel structure. Background Art

[0002] Green buildings refer to buildings that maximize resource conservation (energy, land, water, and materials), protect the environment, and reduce pollution throughout the life cycle of the building, provide people with healthy, applicable, and efficient use of space, and coexist harmoniously with nature. Green buildings are also called ecological buildings or energy-saving and environmentally friendly buildings. The "green" here does not refer to three-dimensional greening or roof gardens in the general sense, but represents a concept or symbol, referring to a building that is harmless to the environment, can make full use of the natural resources of the environment, and is built without destroying the basic ecological balance of the environment. During the construction process of green buildings, steel structures are used to support the construction of the main structure or doors, windows, and other structures.

[0003] Steel structure doors are a common steel structure used in green building construction, usually installed in the emergency passages of green buildings. Steel structure doors can be connected to steel structure frames by welding or rivet structures to achieve high-strength connections. The structure is hollow inside and has a light weight, but has high earthquake and impact resistance, so it has energy-saving effects. Existing steel structure doors only have a barrier function in the event of a fire and cannot have fire-fighting performance. The door handles on the outside of the steel door are usually wrapped with heat-insulating materials, but the door handles on the outside of the steel door may be directly heated by smoke and flames. The heat-insulating materials cannot prevent the temperature from directly heating the door handles, which may cause users to be burned by the door handles when escaping through the fireproof steel door.

[0028] See also Figure 3 The driving mechanism 4 is installed on the front and back of the door body group 2. The driving mechanism 4 includes a hollow box 41. The hollow box 41 can guide the block 42. The hollow box 41 is connected to the door body group 2. The front of the hollow box 41 is penetrated by the block 42, and the block 42 can transmit the inclined rod 44.

[0029] Springs 43 are connected at equal intervals between the block 42 and the hollow box 41, and the springs 43 can drive the block 42 to return. The back of the block 42 is connected to an inclined rod 44 through a hinge, and the inclined rod 44 can transmit power to a long arm 45. The back of the inclined rod 44 is connected to a long arm 45 through a hinge, and the long arm 45 can drive the toothed plate 46 to move. Sliding blocks 451 are connected to both sides of the long arm 45.

[0030] The sliding block 451 is externally slidably connected with a sliding groove block 452, and the sliding groove block 452 is connected to the door body group 2. The sliding block 451 cooperates with the sliding groove block 452 to guide the long arm 45 to make the long arm 45 move linearly. The top of the long arm 45 is contact-connected with a tooth plate 46. The tooth plate 46 and the long arm 45 are not directly connected, but are in a contact relationship. The left side of the tooth plate 46 is connected with a guide block 462.

[0031] The outside of the guide block 462 is slidably connected to a guide groove block 461, which is connected to the door body group 2. The guide block 462 cooperates with the guide groove block 461 to make the tooth plate 46 move in a straight line. The right side of the tooth plate 46 is meshingly connected to a gear 47, which can drive the door handle 3 to rotate. The gear 47 is sleeved on the outside of the door handle 3.

[0032] See also Figure 4The limiting mechanism 5 is installed on both sides of the hollow box 41. The limiting mechanism 5 includes an airbag 51. The airbag 51 is connected to the hollow box 41. A trapezoidal block 52 is connected to the front of the airbag 51. One end of the airbag 51 is fixedly connected to the hollow box 41.

The injection port of the fire extinguisher tank 6 faces the indoor direction of the door body group 2, and a ratchet structure is also installed between the sliding block 521 and the hollow box 41 to prevent the trapezoidal block 52 from returning to its original position, so that the trapezoidal block 52 can continue to press against the switch of the fire extinguisher tank 6 to achieve continuous fire extinguishing and spraying operation.

[0034] In this solution, the door frame 1 is first installed, and then the door body assembly 2 is installed inside the door frame 1. The door body assembly 2 is opened and closed by rotating the door handle 3. When a fire occurs, the flame or smoke will heat the outside of the door body assembly 2, and then the air bag 51 will be driven to extend through the principle of thermal expansion and contraction, and then the trapezoidal block 52 will be driven to move, so that the trapezoidal block 52 slides out of the bottom of the block 42, and the restriction on the block 42 is released. The user kicks the block 42, and then drives the inclined rod 44 to drive, thereby driving the long arm 45 to rise, and finally drives the gear 47 to mesh with the gear 47 to rotate, and drives the door body assembly 2 to open. At the same time, when the trapezoidal block 52 is driven, it can drive the switch of the fire extinguisher tank 6 to work, and then the fire is extinguished;

[0035] When a fire occurs, the user can kick the drive mechanism 4, which in turn drives the door handle 3 to rotate and control the opening and closing of the door body group 2, to prevent the high-temperature door handle 3 from burning the user's palm. At the same time, the drive mechanism 4 is controlled by the limiting mechanism 5, so that the limiting mechanism 5 can only limit the drive mechanism 4 by high-temperature unlocking in case of a fire, to prevent the drive mechanism 4 from being kicked by the user when there is no fire, thereby affecting the use effect in case of a fire. At the same time, the outside of the door body group 2 is sprayed with environmentally friendly fire-retardant paint, which is green and environmentally friendly.
