The specific embodiment

Further auspiciously in conjunction with the accompanying drawings add explanation;

As Fig. 1, shown in 3, link gear is that the structure of spring action formula is, the top board 2 of the web 1 of channel-section steel type and two vertical edge 3 (left sides, the right side) the supporting sealing device that is equipped with in the groove 4 that forms is, has weather strip 5, its cross section is " worker " font, the fixed open slot that is contained in the elongate member 6 that is arranged in groove 4 that complements one another, the cross section of elongate member 6 is the open slot shape of under shed formula, and it is supporting with groove 4, articulated joint 8 is housed on the end face of elongate member 6, rotary head 10 on the lower end of articulated joint 8 and action bars 9 formula that complements one another is hinged, and rotary head 10 can be spool freely to rotate according to the axis of action bars 9; Be upward through after the top board 2 of web 1 after the action bars 9 cover upper springs 7, operating grip 15 be housed on it, the also fixed spacing bar 12 that is equipped with, on top board 2, be equipped be with locator card 13 and with the supporting reference column 14 of spacing bar 12; Spacing bar 12 is at least one, is preferably two, and locator card 13 is at least one and is preferably four.Promote action bars 9 by operating grip 15, and while rotating operation bar 9, make spacing bar 12 supporting being stuck on the corresponding locator card 13, so the 7 compressed whiles of spring, elongate member 6 rises together with weather strip 5, thereby removes shutoff; Reverse operating then makes weather strip 5 transfer, thereby realizes shutoff; Weather strip 5 is transferred when realizing shutoff and the size of pressure between the Roofing slab face, depends on the downforce of action bars 9 or the prestressed size of spring 7.

As Fig. 2, shown in 3, link gear is that the structure of threaded function formula is, in the groove 4 of the top board 2 of the web 1 of channel-section steel type and two vertical edge 3 formation supporting sealing device being housed is, has weather strip 5, its cross section is " worker " font, the fixed open slot that is contained in the elongate member 6 that complements one another and be arranged in groove 4, the cross section of elongate member 6 is the open slot shape of under shed formula, and it is supporting with groove 4, articulated joint 8 is housed on the end face of elongate member 6, rotary head 10 on the lower end of articulated joint 8 and action bars 9 formula that complements one another is hinged, rotary head 10 can be that axle freely rotates according to the axis of action bars 9, and it is shaft-like that action bars 9 is screw thread, is upward through the top board 2 of web 1, be screwed into simultaneously and pass after the supporting nut 11 that is contained on the top board 2, its rod end is equipped with operating grip 15.Rotate and lifting action bars 9 by operating grip 15, promptly drive elongate member 6 and rise together with weather strip 5, thereby remove shutoff, reverse operating then makes weather strip 5 transfer, thereby realizes shutoff.Weather strip 5 is transferred when realizing shutoff and the pressure size between the Roofing slab face, depends on the size of the downforce of action bars 9.

As shown in Figure 3, rotary head 10 on the lower end of action bars 9 with the articulated structure of articulated joint 8 is, articulated joint 8 is a perpendicular type spare, it has the gap 16 supporting with rotary head 10 on one side, on the end face that is welded on elongate member 6 that another side is vertical, action bars 9 pushes gap 16, and rotary head 10 free shapes are between the end face of the right-angle side of being with gap 16 and elongate member 6; The supporting sealing device of a general large form, the latter's length equals the former width, and respectively establishing an action bars 9 by position, two on each sealing device, promptly respectively join an articulated joint 8, and relatively export-oriented shown in Fig. 3 (a) and putting preferably on the length direction of sealing device of the gap 16 in two articulated joints 8, difficult introversion is put in opposite directions, and is more in the same way difficult and put, so that the position stability of elongate member 6, and be easy to safeguard.

As shown in Figure 1, 2, web 1 with the bindiny mechanism that the detachable property of template is fitted together is, on the same side of web 1, be welded with the junction plate 17 of band connecting hole, associated mechanisms on this plate and large form root limit are stupefied is supporting, the two can interconnect by securing member, and must guarantee, after the two interconnects, the left surface of the left vertical edge 3 of web 1 can be close on the stupefied outerplanar in large form root limit, and when the weather strip 5 of sealing device was realized shutoff, elongate member 6 must not be deviate from groove 4; Two cover junctor structures need be arranged on each sealing device at least.

As shown in Figure 1, 2, weather strip 5 has the left foot 18 that directly links to each other with its bottom surface, and the left surface of the left vertical edge 3 of the left surface of left foot 18 and web 1 is positioned at same plane.

Weather strip 5 adopts resilient rubber, plastics or rubber-plastics material to make.
