Problems solved by technology

[0005] In order to solve the above traditional problems, the purpose of the present invention is to provide a floor entrance and exit device for elevators. One of the purposes is to effectively control the warping of the panel by alleviating the restraint of the panel by the reinforcement member or the liner when the panel undergoes thermal expansion during a fire. To prevent the fire gate from falling off and improve the fire performance

Abstract

This elevator landing entrance device comprises a surface plate 4 constituting a decorated face of a vertical frame 2 of a jamb; a reinforcing member 5 enabling the surface plate 4 to slide at a joint part in a horizontal direction at the time of thermal expansion of the surface plate 4; and a fire protecting shutter 10 guided by a rail groove 12 and lowered by an upper frame 3 of the jamb. As another constitution of this invention, the reinforcing member 5 is composed of a material having a linear expansion coefficient larger than the surface plate 4, or ends are rotatably jointed to both ends of the surface plate 4 at stepped positions against a horizontal direction, bridging both ends of the surface plate 4. The rear plate 6 is separated from the surface plate 4 and jointed with the reinforcing member 5.

Description

technical field [0001] The invention relates to a floor entrance and exit device of an elevator, in particular to a three-sided frame of the elevator. Background technique [0002] Figure 7 It is a schematic configuration diagram showing the floor entrance and exit device of an elevator viewed from the floor entrance and exit side of a general elevator. exist Figure 7 Among them, 1 is the floor entrance and exit door of the elevator, 2 is the three-sided frame mullion arranged opposite to the left and right, and 3 is the upper frame of the three-sided frame. Figure 8 yes Figure 7 The horizontal section view of the three-sided frame mullion of . exist Figure 8 Among them, 4 is a panel, and 5 is a reinforcing member. The face plate 4 and each end of the reinforcement member 5 are fixed by welding, and 5a is the welded fixing part. [0003] In the event of a fire, fire gates are sometimes installed on three-sided frames for the purpose of improving fire performance. ...
