Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to fire-fighting doors and windows with good sealing performance. Background Art

[0002] Doors and windows are divided into enclosure components or partition components according to their location. They have different design requirements and should have functions such as thermal insulation, heat insulation, sound insulation, waterproofing, fire prevention, etc. The new requirement is energy saving. The heat lost through gaps in doors and windows in cold areas accounts for about 25% of the total heating heat consumption. The airtightness requirement of doors and windows is an important part of energy-saving design. Doors and windows are important components of the building envelope system. Doors and windows are important components of architectural shape (virtual-real contrast and rhythmic artistic effects play an important role). Therefore, their shape, size, proportion, arrangement, color, shape, etc. have a great influence on the overall shape of the building.

[0003] The existing fire doors and windows have poor sealing performance, resulting in that when the fire doors and windows are in use, when the upper and lower ends are pulled through the hinges to rotate and are in a closed state, there is still a gap in the contact seal between the sealing strip and the door frame. When the contact is too tight, it is easy to cause large friction resistance, making it inconvenient to open and close; when the contact is not tight, the sealing cannot be guaranteed. Therefore, a fire door and window with good sealing performance is proposed to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides fire doors and windows with good sealing properties. When the doors and windows are in a closed state, the connection between the doors and windows and the door frames is more tightly sealed, and rainwater is less likely to penetrate. This solves the problem that when the existing fire doors and windows are in use, the sealing properties are poor when the contact between the doors and windows and the door frames is too loose, and rainwater is easily penetrated.

[0005] To achieve the above object, the utility model provides the following technical solution: a fire door and window with good sealing performance, comprising a bottom plate, a door frame is fixedly connected to the top of the bottom plate, and a sealing component is arranged on the surface of the door frame;

[0006] The sealing assembly includes doors and windows, which are hinged to a door frame, a first sealing gasket is fixedly connected to the inner wall of the door frame, a limit stop plate is fixedly connected to the inner wall of the door frame, a second sealing gasket is fixedly connected to the back of the door and window, two fixing plates are fixedly connected to the top of the base plate, the interiors of the two fixing plates are both threadedly connected with first fastening bolts, and the door frame is fixedly connected to the two fixing plates via the first fastening bolts.

[0007] Furthermore, a first mounting groove is provided inside the bottom plate, and the bottom of the door frame is located inside the bottom plate through the first mounting groove.

[0008] Furthermore, four hinges are fixedly connected to the outer surface of the door frame, and the four hinges are symmetrically distributed on the outer surface of the door frame in groups of two each. The door and window are hinged to the door frame via the four hinges.

[0009] Furthermore, transparent glass is fixedly connected to the inside of the door and window, a handle is fixedly connected to the outer surface of the door and window, and an anti-slip pad is fixedly connected to the outer surface of the handle.

[0010] Furthermore, two second fastening bolts are fixedly connected to the interior of the door frame, the limit baffle is fixedly connected to the door frame via the two second fastening bolts, and the first sealing gasket and the second sealing gasket are in the shape of annular gaskets.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] 1. The fire-fighting doors and windows with good sealing performance, when the doors and windows are installed to the outer surface of the door frame through hinges, the limit baffle is fixedly connected to the door frame through the second fastening bolts. When the doors and windows are in close contact, the second sealing gasket contacts the limit block for sealing. At the same time, when the doors and windows are in a closed state, the first sealing gasket will be squeezed, thereby achieving the purpose of good overall sealing effect and preventing rainwater from penetrating as much as possible.

[0013] 2. The fire-fighting door and window with good sealing performance is provided with a limit baffle and a second sealing gasket, so that when the door and window are in a closed state, the second sealing gasket can be in a close contact state with the limit baffle, and at the same time, the opposite side of the door and window adopts a cross design to prevent rainwater from penetrating as much as possible, thereby further improving the sealing performance. The first fastening bolts are connected to the internal threads of the two fixing plates, so that the door and window can be quickly assembled during assembly, thereby achieving the purpose of improving assembly efficiency.
