Description
Technical field
The utility model relates to bridge construction technical field, specifically relates to a kind of braced structures of bridge expanssion joint pecten.
Background technology
Bridge expanssion joint refers to as preventing bridge beam body component due to climate temperature change (heat expansion, shrinkage), structure is made to produce crack or destruction and a build joint arranging along the suitable position in bridge beam body constuction joint direction, generally arrange between two beam-ends, between beam-ends and abutment or in the articulated position of bridge, to meet the requirement of bridge floor distortion.
When there is the disasters such as earthquake, between bridge beam body, generation transversion malposition is moved, general each bridge expansion joint installation is under this transversion malposition migration, the damage phenomenons such as supporting traverse fractures, bearing comes off can be produced, the board-like bridge expansion joint installation of comb is under this transversion malposition migration, comb easily wrecks, and bolt frangibility comes off, thus causes whole expansion gap device to damage.
In existing technology, had the more advanced shrinkage joint that can meet above-mentioned transversion malposition movement, but its weight capacity there is certain defect, when running into vehicle weight, the damage of whole expanded joint structure can be caused, affecting the quality of whole bridge.
So, urgently develop one and can either meet and produce transversion malposition between bridge beam body and move, there is again the bridge expanssion joint of good supporting capacity.
Utility model content
The technical problem that the utility model solves is to provide one and can either meets and produce transversion malposition between bridge beam body and move, and has again the braced structures of the bridge expanssion joint pecten of good supporting capacity.
The technical solution of the utility model is, a kind of braced structures of bridge expanssion joint pecten, comprise pecten, base plate, bolt, nut I, resilient sleeve, back-up block, cushion, safety supports bolt, nut II, spring, longitudinal embedded bar, laterally pre-reinforcing bar, described pecten is L shape, described pecten is made up of the long section of L shape side and short section of opposite side, described short section has through hole and groove I, pecten is fixed on Liang Tishang by through hole by described bolt, described nut I matches with described bolt, described base plate has groove II, described back-up block upper end is inserted in groove I, lower end is inserted in groove II, pecten and base plate couple together by described safety supports bolt, centre is provided with spring.
Further, described groove I is identical with described groove II geomery, and the cross section of the two is the rectangle with chamfering.The cross sectional dimensions of groove I is greater than the size of back-up block cross section, to the transverse shifting of pecten and vertically move reserved certain space.
Further, the lateral length of the cross section of described through hole is greater than vertical height.Meet pecten transversion malposition and move requisite space, ensure the stable of vertical supporting.
Further, the external surface shape of the cross section of described resilient sleeve is identical with the inner surface configuration of described through hole, and the inner surface configuration of described resilient sleeve is identical with the external surface shape of described bolt.Resilient sleeve and through hole and bolt fit tightly, and play certain cushioning effect.
Further, described cushion is spill, and bottom shape is identical with groove I shape, and middle groove shapes is identical with back-up block shape of cross section.Cushion and groove I and back-up block 6 fit tightly, and while the horizontal and vertical displacement space of guarantee pecten, play buffering and stable effect.
Further, seal washer is provided with between described nut II and pecten.Sealing ring can isolate rainwater and the dirt of bridge floor, ensures that shrinkage joint internal construction is not damaged.
The utility model surveys beneficial effect, and the utility model structure can either meet and produces transversion malposition between bridge beam body and move, and has again good supporting capacity.

Detailed description of the invention
The utility model is described in detail, to make advantage of the present utility model more obvious below in conjunction with detailed description of the invention.
A kind of braced structures of bridge expanssion joint pecten, comprise pecten 1, base plate 2, bolt 3, nut I4, resilient sleeve 5, back-up block 6, cushion 7, safety supports bolt 8, nut II9, spring 11, longitudinal embedded bar 12, laterally pre-reinforcing bar 13, described pecten 1 is L shape, described pecten 1 is made up of the long section 101 of L shape side and short section 102 of opposite side, described short section 102 has through hole 103 and groove I104, described back-up block 6 upper end is inserted in groove I104, lower end is inserted in groove II201, described groove I104 is identical with described groove II201 geomery, the cross section of the two is the rectangle with chamfering, the cross sectional dimensions of groove I104 is greater than the size of back-up block 6 cross section, to the transverse shifting of pecten and vertically move reserved certain space, the lateral length of the cross section of described through hole 103 is greater than vertical height, meet pecten transversion malposition and move requisite space, ensure the stable of vertical supporting, pecten 1 is fixed on beam body 14 by through hole 103 by described bolt 3, and described nut I4 matches with described bolt 3, and described base plate 2 has groove II201, the external surface shape of the cross section of described resilient sleeve 5 is identical with the inner surface configuration of described through hole 103, the inner surface configuration of described resilient sleeve 5 is identical with the external surface shape of described bolt 3, resilient sleeve and through hole and bolt fit tightly, and play certain cushioning effect, described cushion 7 is spill, bottom shape is identical with groove I104 shape, and middle groove shapes is identical with back-up block 6 shape of cross section, and cushion 7 fits tightly with groove I and back-up block 6, while the horizontal and vertical displacement space of guarantee pecten, play buffering and stable effect, be provided with seal washer 10 between described nut II9 and pecten 1, sealing ring can isolate rainwater and the dirt of bridge floor, ensures that shrinkage joint internal construction is not damaged, pecten 1 and base plate 2 couple together by described safety supports bolt 8, and centre is provided with spring 11.
