Description
Technical field
The present invention relates to be used for highway, railway, Bridges on Urban Rail Transit sound barrier sound barrier basis connecting bolt can
Maintenance formula base and the sound barrier with the base, and in particular to railway sound barrier biases steel column, belong to sound-screen barrier technique neck
Domain.
Background technology
At present domestic built or highway in course of construction, railway, Bridges on Urban Rail Transit sound barrier basis connect spiral shell
Bolt is arranged substantially at the medial and lateral of the both sides of H profile steel column, i.e. sound barrier, is symmetric, and inserts sound-absorbing barrier
Afterwards, the bolt on the outside of sound barrier is caused to be difficult to repair and maintenance operation.
In later stage operation maintenance, because sound barrier screen body is intercepted, needs cover a long distance around the outside of sound barrier
Anchor bolt of the maintenance positioned at outside；It is abnormally dangerous or the artificial facility that sets up is climbed to sound barrier outside, and it is related to overpass
Outside when, manpower cannot be climbed, cause bolt on the outside of sound barrier be difficult to conventional maintenance, maintenance.Through long-time vehicle
Operation, anchor bolt is likely to occur loosening, causes sound barrier unstability, sheet material to drop, and causes casualties, property loss, impact
Railways train operation, consequence is very serious.
For case above, each manufacturer and R＆D institution develop various counte-rplan, to solving the problem, have
Representational scheme has opening boxlike steel column bearing and inverted L shape bias steel bracket；This two kinds of technical schemes can be solved in the future
The problem that foundation built-in bolt is safeguarded, but cost is high and easily conflicts with the installation generation of sound barrier unit, in appearance forrns also extremely
It is simple and crude.
The defect of opening boxlike steel column bearing technical scheme has：
1st, the boxlike steel column bearing that is open substantially will be moved on steel sole plate using all side coamings and produce service clearance；
2nd, double walled floor+week side coaming is needed, weight is big, and cost is very high；
3rd, during running status, two gusset plates are subjected to very big tension, very high to welding requirements；
4th, the acoustic barrier unit board between two bearings needs special, non-design and installation groove position, to acoustic barrier unit board
Making brings very big inconvenience；
5th, the boxlike steel column bearing that is open occupies setting height(from bottom), and upper unit plate hight metric lattice cannot be general.
The defect of inverted L shape Eccentric Steel support technology scheme has：
1st, inverted L shape bias steel bracket has substantially made one piece of inner opening cell board with steel plate, and weight is big, and cost is high；
2nd, pre-embedded bolt skew is arranged, and is produced using customization units plate aperture position and is safeguarded space, narrower in operation；
3rd, mode connects for screw, position is used equally to check dimension after installing in outside, upper unit plate between inverted L plate and steel column
Shield, and the M6 self threading pins extremely easy corrosion in the wild for adopting；
4th, likewise, inverted L shape bias steel bracket occupies setting height(from bottom), upper unit plate hight metric lattice cannot be general.
Therefore it provides a kind of be easy to Inspection and maintenance, improve the security of sound barrier, can meet existing or upgrading sound barrier
The railway sound barrier that cell board is general, need not carry out cell plates high adjustment and adapt to the installation on bridge at expansion joint comprehensively
Biasing steel column just becomes the technical barrier that the technical field is badly in need of solving.
The content of the invention
It is an object of the invention to provide a kind of be easy to Inspection and maintenance, improve the security of sound barrier, can meet existing or rise
The acoustic barrier unit board of level is general, need not carry out cell plates high adjustment and adapt to the installation on bridge at expansion joint comprehensively
Railway sound barrier biases steel column.
For achieving the above object, the present invention takes technical scheme below：
