The specific embodiment
The present invention is further described below in conjunction with drawings and embodiments
As shown in Figure 1, the present invention includes fixedly roof system 5,6 of 4,7 and two of 3,8, two groups of V-arrangement line slideways of 2,9, two slip roof systems of 1, two junction plate of linkage; Two fixedly roof system 5,6 is tilting respectively on the anchor post of both sides, every fixedly its incline direction of roof system upper edge be respectively arranged with the top one section friction factor one group V-arrangement line slideway littler than following one section friction factor, two groups of V- arrangement line slideways 4,7 are connected with each self-corresponding slip roof system 3,8 respectively, the upper end bottom surface of two slip roof systems 3,8 is connected with an end of each self- corresponding junction plate 2,9 respectively, the other end of two junction plates 2,9 connects two slip roof system 3,8 roof intersection with linkage 1
As shown in Figure 3, described linkage 1: comprise sleeve 12, spring 10, pin loaded axle 11, reaction rod 13, reaction box 14; Sleeve 12 is inverted and is inserted in the reaction boxes 14, in the reaction box 14 reactive material is housed, and assembles spring 10, pin loaded axle 11 and reaction rod 13 in the sleeve 12 from top to down successively, and reaction rod 13 contacts with reactive material in the reaction box 14.
As shown in Figure 1, V-arrangement line slideway 4, V-arrangement line slideway 7, fixedly roof system 5, fixedly roof system 6 is fixedly mounted on the building foundation.In order to obtain reliable frictional force, guide rail all adopts the V-arrangement line slideway.Slip roof system 3, slip roof system 8 are installed in respectively on the bearing surface of corresponding guide rail separately. and when the roof was closed, junction plate on the two slip roof systems 2,9 interconnected by linkage 1, and joint face is a pin loaded axle outer sleeve face, as shown in Figure 3.Make the slip roof system form an integrated stand on the V-arrangement line slideway like this, and can not glide.When the condition of a fire, make linkage 1 rupture by trigger mechanism, two slip roof systems were opened in 3,8 minutes, thus along V-arrangement line slideway downslide separately, this moment, the roof was opened.As shown in Figure 2, two equal segments (U1=U2) before and after the V-arrangement line slideway divides, the friction factor of two sections V-arrangement line slideway is different, above one section friction factor littler than following one section friction factor.When the slip roof system has just begun to glide its gravity along the component on inclined-plane greater than frictional force, this moment the roof system acceleration alpha maximum of sliding, speed of service v is zero.Frictional force increases gradually in the process that the slip roof system glides, and acceleration alpha progressively reduces, when acceleration alpha is reduced to zero, and slip roof system gliding speed v maximum.When the slip roof system continue to glide, frictional force was greater than partical gravity, the retarded motion of roof system, and the roof system speed v of to the last sliding is kept to zero.Speed v was zero just when the design by the friction factor size can guarantee that roof system is covered stroke.
In Fig. 3, spring 10 is housed from top to bottom, pin loaded axle 11, reaction rod 13 in the sleeve 12.Under normal circumstances, pin loaded axle 11 is at shown position, and pin loaded axle 11 and sleeve 12 are carrying the shear stress that junction plate applies together.When the condition of a fire takes place when, temperature (smog) sensor sends triggering signal and gives flip flop equipment, flip flop equipment makes the material of reaction rod 13 and reaction box 14 the insides react, and during loss for reaction, pin loaded axle 11 leaves original position and down moves reaction rod 13 under the thrust of spring gradually.When being reacted to certain degree, pin loaded axle 11 leaves initial position fully, and this moment, shear stress was born separately by sleeve 12 fully, and therefore sleeve 12 is cut off owing to can't bear so big shear stress, thereby realizes the separation of two junction plates.
