Description
- The invention relates to a safeguard device applied in buildings, and more particularly to an escape chute. The invention is a later application of a
Chinese prior application No. 201110065649.8 CN102114311A , titled an escape chute from skyscrapers. - With the rapid development of society and economy, the available building land is increasingly scarce, and thus to construct skyscrapers has become an inevitable trend. However, the skyscrapers generally have weak feedback mechanisms for disasters, for example, when fire disaster happens, how to escape from the skyscrapers becomes an international tough problem. Chinese prior application titled an escape chute from skyscrapers solves the problem to some extent. The prior application has the following characteristics: 1) in the non-disaster period, the chute can be erected up and leans against the middle standing wall of the stairs, thereby being free of interfering with the ordinary use of the stairs. When disaster occurs, the chute can be laid down to form a U-shaped sliding channel for people to escape. 2) The chute includes a mechanical interlocking device which can trigger a domino effect so that when one chute in a specific storey is turn over, the other downstream chutes automatically turn over whereby forming a continuous escape channel. 3) the escape chute includes a turning chute at the terrace of the stair. The turning chute includes a front section, a middle section, and a rear section, which are connected to the upper straight chute and the lower straight chute, respectively, to form an integrated structure. The turning chute has proper slope, gradient, and curvature and thus when evacuation people slide to the turning chute, the sliding speed is lowered but the sliding is still continuing, which ensures the sliding safety and improves the evacuation efficiency. The prior application effectively solves the problem of rapid escape from high rise in case of disaster.
- It is one objective of the invention to perfect the types and shapes of an escape chute disclosed in the prior application titled an escape chute from skyscrapers. The new escape chute is convenient for use, safe and fast for people to evacuate, and is reasonably designed to save occupied space as much as possible when it is not used.

Thebaffle 39 separates an upper stairway from a lower stairway from a middle position for allowing the fume to rise regularly. The fume vent and thefume extraction fan 42 are disposed on an outer wall of a top of each floor for allowing the fume of an inner side of the wall to communicate with the ventilation pipe arranged on an outer side of the wall. The ventilation pipe is disposed on an outer side of the wall from the top floor to the ground floor. When two ends of the ventilation pipe are open, a strong gas current is produced inside the ventilation pipe and a negative pressure is formed, so that thefume 43 is able to be extracted out from the stairway to the outdoor space through theventilation pipe 41 while the fume extraction fan is started to work. Once the fume is extracted out, the danger of the fire is largely lowered and is beneficial to the evacuation of the people. - The escape chute of the invention has a reasonable structure and low cost. It is convenient and safe in use, and is suitable for the high-stair buildings. For a building having thirty floors, the escape chute of the invention allows each person to take three seconds to slide over each floor and two minutes to the ground floor. If three persons slide down from each floor, the escape chute allows hundreds of people to evacuate simultaneously. It is preferable to use the escape chute combined with technics of the fire-proof ventilation device.

Meanwhile, the lower straight chute is turned downwardly drawn by the chute-linkedwire rope 27, and thechute base 22A of therear section 22 is allow to connect to the lower straight chute, thereby forming a continuous escape chute. - As shown in
FIGS. 6A ,6B , thechute base 20A of thefront section 20 of the turning chute comprises a front part in a rectangular shape and a rear part in a sector shape. A front end of thechute base 20A of thefront section 20 is in lap joint with a rear end of thechute base 2 of the upper straight chute and is disposed on a supportingplate 2F arranged on the rear end of thechute base 2 of the upper straight chute. A rear end of thechute base 20A of thefront section 20 is in lap joint with an upper end of thechute base 21A of themiddle section 21 and is disposed on a supportingplate 21B of thechute base 21A of themiddle section 21. Thechute base 21A of themiddle section 21 comprises: an inner end being in hinge joint with the middle wall via the secondrotating axle 8, and a rear end being in hinge joint with a front end of thechute base 22A of therear section 22. A rear end of thechute base 22A of therear section 22 is in butt joint with a front end of thechute base 2 of the lower straight chute. - Each hinge joint between the chute bases of corresponding chutes is provided with a
hinge roller 8B. Each butt joint and lap joint is provided with a combinedpulley 6. - As shown in
FIGS. 2-5 , the escape chute is also provided with a chute-linkedwire rope 27, a laterally positioningwire rope 27A, a slidinghole 27B, adetachable device 27C, and apositioning hole 27D to realize the linkage of the chutes and to tie theguard rails 2A at a straight angle to the corresponding chute bases. - Structures and embodiments of the
guard rails 2A are the same those of Example 1, that is, the linkage of theguard rails 2A and functions thereof are realized by using the slidinghole 27B, thedetachable device 27C, thepositioning hole 27D, and the laterally positioningwire rope 27A. - When the upper straight chute is rotated downwardly, the
chute base 20A of thefront section 20 of the turning chute slides downwardly along with the supportingplate 2F of thechute base 2 of the upper straight chute and the supportingplate 21B of thechute base 21 of themiddle section 21. Thechute base 20A of thefront section 20 is then located at theguard rail 2A of themiddle section 21. Thus, the supportingplate 2F of the upper straight chute and the supportingplate 21B of themiddle section 21, thereby forming the lap joint with the upper straight chute and themiddle section 21, respectively. - Structures of the guard rails are shown in
FIGS. 2-6 . Theguard rail 2A of thefront section 20 comprises: a front part divided into two members of the same shapes and in hinge joint with the rectangular-shaped front chute base; and a rear part in hinge joint with the sector-shaped rear chute base. The upper end of theguard rail 2A of thefront section 20 is connected with theguard rail 2A of the upper straight chute, and the lower end of theguard rail 2A of thefront section 20 is connected to guard rails of themiddle section 21, therear section 22, and the guard rail of the lower straight chute one after another. - As shown in
FIGS. 7-8 , the turningchute 7 is provided with a lifting device comprising a liftingslide 32, abalance iron slide 33, apulley 34, ahanging wire rope 35, and a balance iron36. One end of thehanging wire rope 35 is fixed on the balance iron36, and the other end of thehanging wire rope 35 is fixed on the turningchute 7 after passing through thepulley 34. The turningchute 7 comprises a supportingplate 7A on a bottom, and the supporting plate is able to support the turning chute and drive the turning chute to move upwardly and downwardly inside the lifting slide. Thebalance iron 36 is disposed inside thebalance iron slide 33 and is downwardly and upwardly movable in an opposite direction of the movement of the turning chute. - The weight of the
balance iron 36 is relatively light to the weight of the turningchute 7. When the upper straight chute is turned downwardly, the supportingplate 7A of the turningchute 7 is removed from being supported by the coupling devices, thereby sliding downwardly at a uniform velocity under the force of the self-gravity and the drag of thebalance iron 36. A preferable weight difference between the turningchute 7 and thebalance iron 36 is 3 Kg, thereby ensuring that persons will not hurt when they are hit by the descending turning chute. As shown inFIG. 7 , the turningchute 7 employs an integrated structure, the lifting device is arranged on the end face of the middle wall for integrally raising or lowering the turning chute. The turning case can be lifted and fixed at a top of the stairway. In case of fire, the turning chute is dragged downwardly by the upper straight chute on thestair landing 5A, and draws the lower straight chute to descend, thus, a continuous escape chute is formed. - As shown in
FIG. 9 , the escape chute further comprises a fire-proof ventilation device comprising abaffle 39, aventilation pipe 41, a fume vent, and afume extraction fan 42. Thebaffle 39 separates anupper stairway 37 from alower stairway 38 from a middle position for allowing the fume to rise regularly. The fume vent and thefume extraction fan 42 are disposed on an outer wall of a top of each floor for allowing the fume of an inner side of the wall to communicate with theventilation pipe 41 arranged on an outer side of the wall. The ventilation pipe41 is disposed on an outer side of the wall from the top floor to the ground floor. When two ends of the ventilation pipe are open, a strong gas current is produced inside the ventilation pipe and a negative pressure is formed, so that the fume is able to be extracted out from the stairway to the outdoor space through the ventilation pipe while the fume extraction fan is started to work. Once the fume is extracted out, the danger of the fire is largely lowered and is beneficial to the evacuation of people.
