Description

Technical Field

[0001] The utility model relates to the technical field of fireproof construction structures, in particular to a door opening blocking structure. Background Art

[0002] Fireproof rolling shutter doors are a type of fireproof and heat-insulating facility suitable for larger openings in industrial and civil buildings. They can effectively prevent the spread of fire and protect the safety of life and property. They are an indispensable fireproof facility in modern buildings.

[0003] During the installation of fire shutter doors in basements and large shopping malls, the floor heights in basements and large shopping malls are relatively high, and there are some pipes on the door openings. The fire shutter doors cannot reach the top of the door openings. There is a large space above the fire shutter doors that needs to be sealed. The conventional sealing method uses concrete hanging plates to seal the space above the fire shutter doors.

[0004] However, concrete lower hanging plates generally require post-embedded reinforcement construction, which has a long construction period and is difficult to ensure construction quality. In order to avoid the pipes arranged in the upper space of the fire shutter door, it is necessary to drill holes, bury pipes, and seal the concrete lower hanging plates. Moreover, the concrete lower hanging plates have a large deadweight, and the structure of the door opening needs to be reinforced, which greatly increases the construction period and construction difficulty.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0024] Reference Figure 1 and Figure 2 An example of the utility model provides a door opening blocking structure for blocking a door opening 400, comprising a fire shutter door 100 and a fire curtain 200. The fire shutter door 100 is installed at the lower part of the door opening 400, an upper opening is formed between the fire shutter door 100 and the door opening 400, the edge of the fire curtain 200 covers the edge of the upper opening, and a pressing edge assembly 300 is provided on the edge of the fire curtain 200. The pressing edge assembly 300 is used to press the edge of the fire curtain 200 against the edge of the upper opening, so as to seal the upper opening, thereby shortening the construction period, reducing the construction difficulty, and reducing the pressure on the door opening 400.

[0025] Structurally, the fireproof rolling shutter door 100 includes a rolling shutter box 110, a reel 120 rotatably connected to the rolling shutter box 110, a fireproof rolling shutter 130 wound on the reel 120, guide rails 140 respectively arranged on both sides of the fireproof rolling shutter 130, and an electric control device 150 for controlling the rotation of the reel 120. The two ends of the rolling shutter box 110 are respectively fixed on both sides of the door opening 400, and the two guide rails 140 are respectively fixed on both sides of the door opening 400. The side of the door opening 400 can provide support for the guide rails 140. The electric control device 150 controls the reel 120 to rotate forward or reverse to drive the fireproof rolling shutter 130 to reel or unreel. At the same time, the side of the fireproof rolling shutter 130 slides in the guide rail 140, so that the fireproof rolling shutter door 100 can be automatically opened and closed.

[0026] Furthermore, two reels 120 and two fireproof roller shutters 130 are provided, and the two reels 120 are arranged in parallel in the horizontal direction. The electric control device 150 can simultaneously control the two reels 120 to retract and unreel the two fireproof roller shutters 130 respectively, thereby improving the fireproof and heat-insulating effects.

[0027] Furthermore, the bottom ends of the two fireproof rolling shutters 130 are connected by a buckle plate 160, so that the bottom ends of the two fireproof rolling shutters 130 can be raised and lowered at the same time when they are retracted and unreeled, thereby improving the stability of the fireproof rolling shutter door 100.

[0028] Reference Figure 3 Furthermore, after the guide rail 140 is fixed to the side of the door opening 400, the two sides of the guide rail 140 are sealed by the brickwork structure 170. On the one hand, the brickwork structure 170 provides side support for the guide rail 140 to prevent the guide rail 140 from deformation or displacement. On the other hand, it can improve the sealing effect of the guide rail 140, thereby improving the fireproof and heat-insulating effect of the fireproof rolling shutter door 100.

[0029] In some preferred embodiments, there are two fireproof curtains 200, which are arranged on both sides of the rolling shutter box 110, respectively. Specifically, the upper edge and both side edges of the fireproof curtain 200 are respectively fixed on the upper part and both sides of the door opening 400, and the lower edge of the fireproof curtain 200 is fixed on the side of the rolling shutter box 110, so that the upper opening can be double-sealed to further improve the fireproof and heat-insulating effects.

[0030] It should be noted that the fire resistance limit of the fireproof curtain 200 is not less than 3 hours.

[0031] Furthermore, the edge pressing assembly 300 includes a plurality of pressure strips 310 and screws 320. The upper edge and both side edges of the fireproof curtain 200 are respectively fixed to the upper part and both sides of the door opening 400 by a plurality of pressure strips 310. The pressure strips 310 are fixed to the edge of the door opening 400 by expansion screws 320. The lower edge of the fireproof curtain 200 is fixed to the side of the shutter box 110 by a plurality of screws 320. Thus, the edge pressing firmness of the fireproof curtain 200 can be improved, the fireproof curtain 200 can be prevented from falling off, and its service life can be improved.

[0032] Furthermore, the lower edge of the fireproof curtain 200 is sealed with the side of the rolling shutter box 110 by the fireproof sealant 340 , which can prevent smoke and fire from overflowing from the gap between the fireproof curtain 200 and the rolling shutter box 110 .

[0033] Furthermore, the fireproof curtain 200 is provided with holes for accommodating the passage of the pipe 500, and the pipe 500 and the fireproof curtain 200 are sealed by a fireproof sealant 340, thereby facilitating the arrangement of the pipe 500 and reducing the difficulty of construction.

[0034] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
