Description
Technical field
The utility model relates to the machinery folding device that can realize fire-proof function in a kind of heavy construction.
Background technology
The machinery folding device that is used for building fire protection belongs to a kind of of folding house roof.Folding house roof is that a kind of part or all of roof system can move or the form of structure of folding, its realization is that a complete roof structure is divided into several movable and fixed cells according to certain rules, makes mobile unit move the purpose that reaches the roof system folding according to certain track.In China, though built up the folding house roof in several sports palace, generally speaking folding house roof still is in the starting stage, does not also have national standard or local design specifications at present.Though the folding house roof in building fire protection mechanical device and sports palace has certain similarity, they have very big difference on purpose of design and technology emphasis.Because it will satisfy fire-proof function, so its reliability requirement height can be realized passive opening, and will guarantee certain opening speed.
Summary of the invention
In order to realize utilizing folding house roof to reach the purpose of building fire protection, the purpose of this utility model is to provide a kind of building fire protection machinery folding device of opening by deadweight.
The technical scheme that the utility model adopted is:
Comprise linkage, two junction plates, two slip roof systems, two groups of V-arrangement line slideways and two are roof system fixedly; Two fixedly roof system is tilting respectively on the anchor post of both sides, every fixing roof system friction factor one group of V-arrangement line slideway smaller of one section above the both sides of Dou face are respectively equipped with than following one section friction factor, two groups of V-arrangement line slideways are connected with separately slip roof system respectively, the upper end bottom surface of two slip roof systems is connected with an end of junction plate respectively, the other end of two junction plates connects with linkage, two slip roof system roof intersection.
Described linkage comprises sleeve, spring, pin loaded axle, reaction rod, reaction box; Sleeve is inverted in the insertion reaction box, and reactive material is housed in the reaction box, assembles spring, pin loaded axle, reaction rod in the sleeve from top to down successively, and reaction reactive material excellent and in the reaction box contacts.
The beneficial effect that the utlity model has is:
When the condition of a fire took place, machinery folding device can be opened rapidly under the effect of specific drive unit, thereby made ground smog toward rising, and was discharged to outside the building, reduced the influence of smog to the inside personnel, also was fire fighter rescue by force and put out a fire creation time and condition simultaneously.Simultaneously, machinery folding device also should have ventilation and lighting function, wind resistance snow function, the rainproof drain function of roofing.This device reliability height can be opened when the condition of a fire takes place reliably; Can realize passive opening, smooth opening under the effect that does not have drive sources such as electric, machinery; Can guarantee certain opening speed, the whole device time of opening is not more than 45s.

Among the figure: 1. connecting pin, 2. junction plate, 3. slip roof system, 4.V shape line slideway, 5. fixing roof system, 6. fixing roof system, 7.V shape line slideway, 8. slip roof system, 9. junction plate, 10. spring, 11. pin loaded axles, 12. sleeves, 13. reaction rods, 14. reaction boxes.
The specific embodiment
Below in conjunction with drawings and embodiments the utility model is further specified
As shown in Figure 1, the utility model comprises 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 fixing roof system friction factor one group of V-arrangement line slideway smaller of one section above the both sides of Dou face are respectively equipped with than following one section friction factor, article two, V- arrangement line slideway 4,7 is connected with separately slip roof system 3,8 respectively, the upper end bottom surface of two slip roof systems 3,8 is connected with an end of 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 2, 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.The oblique roof system 3 that slides, the oblique roof system 8 that slides 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 pin apparatuses 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 pin apparatuses 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 bigger, below one section friction factor smaller.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.
