Referring to Figures 1 and 2, the present invention is a hermetic fire and smoke prevention roll door structure comprising a roll box portion 10 and a pair of door rail portions 20. The roll box portion 10 has a reel 11 and a fire and smoke prevention roll screen 12, and the fire and smoke prevention roll screen 12 is wound around the reel 11, and can be changed between winding and unwinding. And a hollow sleeve structure 121 is disposed on each side of the fire and smoke prevention curtain 12, and the hollow sleeve structure 121 has a pair of contact segments 12A. The pair of door rail portions 20 are disposed below the magazine portion 10 and correspond to the two hollow bundle structures 121. Each of the door rail portions 20 has a frame body 21, a guiding post 22, a pair of inner limiting pieces 23 and a pair of curved surface guiding portions 24. The guide post 22 is erected in the frame body 21, and the hollow sleeve structure 121 is sleeved on the guide post 22, and can be moved relative to the guide post 22 when being rolled in and out. . The pair of inner limiting flaps 23 are disposed in the frame body 21, and have a passage 231 therebetween for the fireproof smoke prevention curtain 12 to pass; the pair of curved surface guiding portions 24 are disposed on the pair of inner limiting flaps 23 on. Thereby, when the fire and smoke prevention roll screen 12 is unrolled and subjected to an external force P (refer to FIG. 3), one of the pair of contact segments 12A is used to (force) contact the corresponding pair of arcs. One of the surface guiding portions 24, and a planar airtight effect is achieved by corresponding to the curved surface. In practice, the roll box portion 10 is for being disposed above a passage opening (not shown, such as a doorway). The pair of door rail portions 20 are corresponding to the magazine portion 10 and are respectively disposed at two sides of the passage opening. Each of the curved surface guiding portions 24 is one of a combined structure and an integrally formed structure. In the case of a combined structure, it may be in the form of a C-tube (see Fig. 4), corresponding to the end of the inner flap 23, extending into the C-tube structure and fixed. When it is an integrally formed structure, it is directly bonded to the end of the corresponding inner limiting piece 23, and can be further divided into a semicircular structure (refer to FIG. 5), a circular structure (refer to FIG. 6), an elliptical shape. The structure (see Fig. 7), the convex and concave structure (see Fig. 8, the pair of curved surface guides 22 are formed like a two-handed arch). The external force P can be a high temperature gas pressure generated during a fire. This case is mainly used for fire prevention and smoke prevention at the entrance of the building. That is, when one of the two spaces in the building generates high temperature gas pressure (i.e., the external force P) due to a fire, the fire and smoke may spread through the passage opening toward another space. At this time, the air-tight fire and smoke prevention roll door structure is disposed at the passage opening, and the fire and smoke prevention roll screen 12 is rolled out to isolate the two spaces, and when the fire generates high temperature gas pressure (ie, the external force P) is pushed to the fire prevention The smoke-proof roll screen 12 causes the contact portion 12A to be pressed into contact with the corresponding pair of curved surface guiding portions 24, and can be formed into a "face shape" by a curved surface (a non-known point shape or a line shape can be compared) ) Better airtight effect. The fire and smoke of one of the two spaces can be prevented from diffusing through the door rail portion 20 to the other of the two spaces. The advantages and effects of the present invention are as follows: [1] A more airtight effect with a planar shape. When the fire and smoke prevention roll is rolled out and subjected to the high temperature gas pressure generated by the fire, the contact section is (forced) to contact the corresponding curved surface guide portion, and the surface is formed corresponding to the "curved surface" Better airtight effect. Therefore, it has a better airtight effect. [2] The curved guide can be selected according to the needs of different structures. The curved surface guiding portion may be one of a combined structure and an integrally formed structure. In the case of a combined structure, it may be in the form of a C-shaped tube, and the end of the inner limiting flap extends into the C-shaped tube structure and is fixed. When it is an integrally formed structure, it is directly bonded to the end of the corresponding inner limiting piece, and can be further divided into one of a semicircular structure, a circular structure, an elliptical structure, and a convex and concave structure. Therefore, the curved surface guiding portion can select different structures according to requirements. [3] Face contact facilitates relative movement. The fire and smoke prevention roll screen contacts the corresponding curved surface guiding portion with the contact portion (forced), and achieves a "face contact" corresponding to the "arc surface", in addition to achieving a better airtight effect, The relative contact surface is made smoother, which facilitates the relative movement of the fire and smoke prevention curtain and the curved surface guiding portion. Therefore, the surface contact facilitates relative movement.
