Problems solved by technology

[0009] The utility model patent (CN202325149U) discloses a door with a door closing device, which includes a door body and a door seam closing device. The door seam closing device includes a manual transmission mechanism and a baffle plate. The concave cavity where the baffle is placed and adapted to the baffle. The baffle is placed in the concave cavity. The transmission mechanism includes a worm, a worm wheel and a rotating handle. The rotation of the rotating handle drives the rotation between the worm wheel and the worm, so that the baffle is up and down. Move, the baffle of this technical scheme adopts polyolefin foam board, which has poor plasticity and flame retardancy, and needs to make a special door body suitable for the baffle. Dual-purpose (normal and fire) fire door problem, and installation is troublesome

Embodiment 1

[0040] Such as figure 1 As shown, a door bottom gap sealing device, which is located at the bottom of the door body 6, includes a U-shaped guide sleeve 1, a foam glass block 2, a fixing piece, a reinforcement block 4 and an opening and closing bolt 5, and the fixing piece is a notched elastic Ring rubber sleeve 3.

[0041] The width of the U-shaped guide sleeve 1 and the foam glass block 2 is consistent with the width of the door body 6. The U-shaped open end of the U-shaped guide sleeve 1 is downward and fixed on the bottom of the door body 6, and the two ends of the two sides of the U-shaped guide sleeve 1 All are provided with elongated chute 11.

[0042] Such as Figure 2~3 As shown, the height of the foam glass block 2 is greater than the height of the gap at the bottom of the door, and it is embedded in the opening end of the U-shaped guide sleeve 1. The two ends of the foam glass block 2 are provided with pin holes 21, and the elastic ring rubber sleeve 3 is located i...

Embodiment 2

[0054] The door bottom gap sealing device of this embodiment is basically the same as that of Embodiment 1, the difference lies in that the fixing parts are two arc-shaped latches 7 .

[0055] Such as Image 6 As shown, the arc lock 7 includes an arc lock arm 71, a rotating shaft 72 and a magnet-absorbing piece 73. The arc-shaped lock arm 71 is fixed on the U-shaped guide sleeve 1 through the rotating shaft 72, and the magnet-absorbing piece 73 is fixed on the arc-shaped The bottom of the locking arm 71 is in contact with the outer edge, and a pressing portion 74 is provided above the arc-shaped locking arm 71 .

[0056] The installation process of this embodiment is as follows:

[0057] 1. Install and fix the reinforcing block 4 above the foam glass block 2, so that the outer pin hole 41 of the reinforcing block 4 is coaxial with the pin hole 21 of the foam glass block 2.

[0058] 2. Install the two arc locks 7 above the elongated chute 11 of the U-shaped guide sleeve 1 thr...

Abstract

The invention discloses a door bottom seam sealing device and application thereof in a fireproof door and a small refuge room. The door bottom seam sealing device comprises a U-shaped guide sleeve, a foam glass block, fixing pieces and an opening and closing latch; a U-shaped opening end of the U-shaped guide sleeve faces downwards and is fixed at the bottom of a door body; elongated chutes are respectively formed in two ends of each of two side surfaces of the U-shaped guide sleeve; the foam glass block is inlaid in the opening end of the U-shaped guide sleeve; latch holes are formed in two ends of the foam glass block; and the fixing pieces are positioned above the elongated chutes of the U-shaped guide sleeve. The door bottom seam sealing device is simple in structure and wide in application range; requirements of fireproofing and breathability of doors are met; and requirements of residential building are also met.

Description

technical field [0001] The invention relates to the field of architectural design, in particular to a door bottom gap sealing device and its application in fire doors and building refuge rooms. Background technique [0002] Article 5.5.32 of the new version of the "Code for Fire Protection Design of Buildings" implemented on May 1, 2015 stipulates: "For residential buildings with a building height greater than 54m, each household shall have a room that meets the following requirements: [0003] 1. It should be installed against the outer wall, and should be equipped with openable outer windows; [0004] 2. The fire resistance rating of the inner and outer walls should not be lower than 1.00h, the door of this room should be a Class B fire door, and the fire resistance integrity of the outer windows should not be lower than 1.00h. " [0005] In the actual design, the room with the least combustibles in the residential building and with water or wet towels to prevent smoke s...
