Specific embodiment

See also Figure 1 and Figure 2, the present invention mainly comprises supporting seat group 1, height tilt shim pack 2, base group 3 and water collection sheet 4, wherein: supporting seat group 1 comprises stretchable sheet group 12 again, and it is to form by the groove 121 of several independent telescope sheets S and 122 staggered cooperations of tongue piece; Supporting seat group 1 also comprise supporting

seat

111 and 112 and with stretchable sheet group 12 combination, the lug 114 and 115 and the

lug

117 and 118 of stretchable sheet group 12 that promptly

links supporting seat

111 and 112 by diaxon 12A and 12B, in addition, supporting

seat

111 and 112 upper ends can increase thickness, to strengthen support force to diaxon 12A, 12B and lug 114,115,117 and 118, and this supporting

seat

111 and 112 also viewable design need and add ribs 113, with the rigidity intensity of

reinforcement supporting seat

111 and 112; The bottom of base group 3 is provided with

slide slot

33,34, and the side of this

slide slot

33,34 is respectively arranged with

guide groove

31,32; In addition, along this base profile, be provided with several fins B, this fin B is provided with several through holes A; This supporting seat group 1

places pad

21,22 tops of the shim pack 2 that just tilts, and the bottom of this shim pack 2 that just tilts, then be placed on the

slide slot

33,34 of base group 3, the

set guide groove

31,32 of these

slide slot

33,34 sides can cooperate (please cooperate the A referring to Fig. 2) with the

set flange

41,42 in water collection sheet 4 two ends.After the present invention forms, in position, utilize screw M locking supporting seat group 1, height tilt shim pack 2 and base group 3.

Please referring to shown in Fig. 3 A, it is the bridge floor vertical displacement schematic diagram of adjustable road surface expansion gap device; When the pedestal of bridge or pavement of road C is influenced by external force and does vertical displacement, lug 114,115 that supporting seat group 1 is set and the lug 117,118 of stretchable sheet S, can do displacement action with respect to

diaxon

12A, 12B, this moment is by the cooperation of groove 121 and the tongue piece 122 of independent telescope sheet S, in the scope of allowing nargin E, make bridge or pavement of road C can remain on connection status, and do not separate immediately; In addition, because water collection sheet 4 is to adopt elastic water-proofing material made, thus after bridge or pavement of road C displacement, still can compile water W, to keep the function of its draining of catchmenting.

Please referring to shown in Fig. 3 B, it is the bridge floor horizontal movement schematic diagram of adjustable road surface expansion gap device; When bridge or pavement of road C are influenced by external force, become the horizontal direction skew, and when surpassing the design strength of locking screw M, the supported seat group 1 of locking screw M, the height shearing force that is produced between shim pack 2 or the base group 3 that tilts is blocked, this moment, supporting seat group 1 can slippage above inclination shim pack 2, or slippage is done in shim pack 2 bottoms that just tilt in the

slide slot

33,34 of base group 3, this moment is under the rigid structures that does not damage bridge or pavement of road C, be beneficial to maintenance again and the location of bridge or pavement of road C, and need not give up; Same, because water collection sheet 4 is to adopt elastic water-proofing material made, after the bridge floor distortion, still can compile water W, to keep the function of its draining of catchmenting.

See also shown in Figure 4ly, it is that the stretchable sheet pattern of adjustable road surface expansion gap device changes schematic diagram; The independent telescope sheet S that stretchable sheet group 12 is contained, area or environment that visual the present invention uses, change and make different patterns, stretchable sheet 13 as shown in Figure 4, this stretchable sheet 13 has groove 131 and tongue piece 132, this groove 131 and tongue piece 132 can cooperatively interact, and simultaneously at stretchable sheet 13 1 ends, respectively are provided with the

lug

137 and 138 that contains the hole; In addition, the front end that each stretchable sheet was in contact with one another can be made as arcuation or can be designed to other different pattern because of demand.The change of different types, but the variability of the present invention and the scope of application can be increased.

Please referring to shown in Figure 5, it is the height inclination shim pack variation schematic diagram of adjustable road surface expansion gap device; The tiltable pad 21a of height oblique plate group 2a of the present invention and 22a can be designed to an angle D according to actual state, to adjust the planarization on road surface.

See also shown in Fig. 6 A and Fig. 6 B, it is the road surface asymmetric displacement stretchable sheet group variation schematic diagram of adjustable road surface expansion gap device; Stretchable sheet group 12 of the present invention in the permissible scope of stretchable sheet S side nargin, also can cooperate integral body of the present invention, does the action of asymmetric horizontal movement, but increases variability of the present invention.

Please be simultaneously referring to Fig. 7 and shown in Figure 8, Fig. 7 is the space instrument seat mode of occupation schematic perspective view of adjustable road surface expansion gap device, Fig. 8 is the space instrument seat mode of occupation lateral view of this adjustable road surface expansion gap device; This space instrument seat H is a ribs H1, this ribs H1 two ends be fixed with two groups be parallel to each other stride sheet H21 and H22, two spacings of striding sheet H21 and H22 are pre-designed size; The through hole A of the fin B that this base group 3 is contained can be earlier with reinforcing bar T polyphone in advance, be about to base group 3 behind the polyphone again to be embedded in the bridge that two desires link or the two sections of road in advance, the polyphone of this reinforcing bar T can increase the pull-out capacity of base group 3 and bridge or road; At first, with space instrument seat H stride sheet H21 and H22 places on the slide slot 33 and 34 of base group 3, please cooperate referring to Fig. 2, Fig. 7 and Fig. 8, by the design of the width of space instrument seat H, determined the spacing of two base groups 3 after, remove space instrument seat H again; Secondly, the bottom of the shim pack 2 that will just tilt again places on the slide slot 33,34 of base group 3; Afterwards, supporting seat group 1 is positioned over the top of height oblique plate group 2, by diaxon 12A, 12B assembling and adjust stretchable sheet group 12 and be placed on the set lug 115 of supporting seat group 1; At this moment, again by screw M lock respectively supporting seat group 1, height tilt shim pack 2 and base group 3; At last,, cooperate the guide groove 31,32 of base group, load onto water collection sheet 4 with the flange 41,42 of water collection sheet.

According to aforesaid structure, the method for the present invention's installing comprises following steps:

1, space instrument seat is placed in the slide slot of base group, by the width of space instrument seat, determine two base groups spacing and pre-buried fixing after, remove space instrument seat again.
