Description
Technical field
The present invention relates to Architectural Equipment technical field more particularly to a kind of buffer-type bridge extension joints.
Background technique
Bridge refers generally to be erected in rivers,lakes and seas, the structures for making traffic etc. that can smoothly pass through.It is modern to adapt to
The transportation industry of high speed development, bridge be also extended to across mountain stream, unfavorable geology or meet other traffic need and set up make
Current more convenient and fast building.Bridge is generally made of superstructure, substructure, support and attached structure, top knot
Structure is also known as bridge span structure, is across the primary structure of obstacle；Substructure includes abutment, bridge pier and basis；Support is spanning knot
The load transfer device of the bearing place setting of structure and bridge pier or abutment；Attached structure then refer to transition slab at bridge head, truncated cone banking, shore protection,
Training works etc..In the prior art, bridge mostly uses pitch to fill, so greatly when building bridge body between bridge
Although playing buffer function, it is not connected firmly, the rugged performance of bridge entirety reduces, and accordingly, there exist rooms for improvement.
Summary of the invention
The object of the invention is that providing a kind of buffer-type bridge extension joint to solve the above-mentioned problems.
The present invention through the following technical solutions to achieve the above objectives:
The present invention includes bridge, pre-buried steel part, connection steel loop, connection bolt, cushioning materials connecting cover plate, buffering
Steel spring plate, connection shaft and bridge deck concrete, the pre-buried steel part freeze solidly on the end of the bridge, the pre-buried steel part
Upper end be exposed to the upper surface of the bridge, the connection steel loop is fixed by the connection bolt and the pre-buried steel part
It connects, passes through the both ends of the connection shaft and the buffer spring steel plate between the connection steel loop of two sections of bridges
Between be rotatablely connected, the bridge deck concrete freeze solidly on it is described connection steel loop two sides, the cushioning materials connecting cover plate
It is fixed on the bridge deck concrete on two sections of bridges.
The cushioning materials connecting cover plate is by iron, titanium, chromium, natural rubber, acrylic resin, aluminium oxide ultra micro
Powder, ethylene glycol, diethanol amine, triethyl group diamines, carborundum grain, sodium hydroxide and polyether polyol are made；
It uses metal working process to be prepared into the iron, titanium, chromium metal net shaped, then natural rubber heating is melted
Change, acrylic resin, aluminium oxide Ultramicro-powder, ethylene glycol, diethanol amine, triethyl group two will be added in the natural rubber after thawing
Amine, carborundum grain, sodium hydroxide and polyether polyol are stirred evenly in the case where keeping the temperature melting state；Metal mesh is put into mold
In, the mixture for pouring into thawing is filled in metal mesh, and sizing to be cooled demoulds.
Preferably, the iron, the titanium, the chromium mass ratio be 8:1:1.
Preferably, the natural rubber, the acrylic resin, the aluminium oxide Ultramicro-powder, the ethylene glycol, described two
Ethanol amine, the triethyl group diamines, the carborundum grain, the sodium hydroxide and the polyether polyol mass ratio be 6:
1:2:2:1:1:3:1:2.
The beneficial effects of the present invention are:
The present invention is a kind of buffer-type bridge extension joint, and compared with prior art, the present invention is made by the design of structure
Bridge is connected firmly, and be provided simultaneously with cushion performance, meanwhile, using the not only intensity of cover board made of proportion material of the invention
Height, and shock absorbing effect is further played, guarantee to increase shock absorbing effect in the case where bridge intensity, has and push away
The value extensively applied.
