Abstract
The invention discloses a kind of for dividing the anti-throwing net of band in bridge, and the anti-throwing net of half elliptic, which is anchored on the inside of the width bridge of left and right by the way of crossing over, divides band in anti-collision wall guardrail top and covering bridge.Bridge of the present invention suitable for construction initial stage without anti-throwing net design has smaller front face area, more existing to commonly use anti-throwing web area reduction about 71%, while preventing object from leaving, can be avoided parabolic and springs back into lane influence traffic safety.Can be applied in framing bridge divide prevents anti-cast for leaving object influence bridge down train safety from applying with installation on concrete anti-collision wall, combined type guard bar.
Description
Technical field
It is the invention belongs to anti-throwing network technology field, in particular to a kind of for dividing the anti-throwing net of band in bridge, specifically one
Kind increases the anti-throwing net of half elliptic in the framing type formula bridge of left and right at point band.
Technical background
A point band, which is prevented casting applying, in existing highway framing type bridge mostly uses upright anti-throwing web form.For example, concrete structure
It is mostly be anti-collision wall top surface be arranged the anti-throwing net of vertical type, steel reinforced concrete combination anti-collision wall the anti-throwing of vertical type is set mostly on the outside of anti-collision wall
Net, and in point band a two sides anti-collision wall be both needed to be arranged.For the anti-throwing net of vertical type because highly higher, front face area is larger, so to guarantee
Safety, need to when anti-collision wall pours the attachmentes such as preburied column, ring flange or foundation bolt, attachment quantity is more, and cost is higher.
Vertical type anti-throwing net needs to carry out when newly-built pre-buried, and it is more difficult when being further added by that the later period is in need.The anti-throwing net of vertical type is being driven a vehicle
Because easily entering fast and runway after highly higher item rebound when parabolic, traffic safety is seriously affected.
Summary of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, provide a kind of for dividing the anti-throwing of band in bridge
Net is a kind of for dividing band is anti-to cast the anti-throwing net of abnormity applied in increasing on being completed bridge, is anchored by the way of leap
Divide band in anti-collision wall guardrail top and covering bridge on the inside of the width bridge of left and right.Anti- throwing net provided by the invention is suitable for building just
Phase without the anti-bridge for throwing net design, has smaller front face area, more existing to commonly use anti-throwing web area reduction about 71%, prevents object
While body leaves, it can be avoided parabolic and spring back into lane influence traffic safety.
Technical solution is as follows:
It is a kind of for dividing the anti-throwing net of band in bridge, which is characterized in that the anti-throwing net of half elliptic using cross over by the way of anchor
Gu dividing band in anti-collision wall guardrail top and covering bridge on the inside of the width bridge of left and right.
Further, the anti-cartouche long axis for throwing net of the half-oval shaped is 66cm, short axle 40.8cm.
Further, the anti-throwing net of the half-oval shaped is a pair of two-by-two using L50X32X4 angle steel and spacing 2m be anchored at it is mixed
The top of solidifying soil anti-collision wall.
Further, the anti-steel plate supporting network for throwing net in the centre of anchoring angle steel spacing using 50x4 of the half-oval shaped
Piece.
Further, the anti-braided mesh size 30x40cm for throwing net of the half-oval shaped.
Further, the anti-steel plate base thrown net anchoring angle steel and be welded on 160x160cm of the half-oval shaped.
Further, the steel plate base is anchored in concrete anti-collision wall using expansion bolt.
Further, the steel plate base anchoring expansion bolt uses the quadrangle at away from steel plate edge 3cm four M16X120
Symmetrical anchoring.
Further, angle steel, steel plate support and the mesh sheet for welding Junk prevention net soak the anti-corrosion of modeling using first galvanizing by dipping again
Treatment measures, leaching modeling layer is with a thickness of 0.5~0.6mm.
The present invention provides a kind of simple possible, anti-cast of point band is applied in separate type bridge convenient to carry out, suitable for building
Initial stage is made without the anti-bridge for throwing net design, there is smaller front face area, it is more existing to commonly use anti-throwing web area reduction about 71%, prevent
While only object leaves, it can be avoided parabolic and spring back into lane influence traffic safety.It can be applied in framing bridge divide band
Installation prevents anti-cast for leaving object influence bridge down train safety from applying on concrete anti-collision wall, combined type guard bar.

Specific embodiment
To make those skilled in the art more fully understand technical solution of the present invention, below with reference to embodiment to the present invention
Offer it is a kind of for dividing the anti-throwing net of band to be described in detail in bridge.Following embodiment is merely to illustrate the present invention rather than uses
In limiting the scope of the invention.
Embodiment 1
In the Class I highway framing type bridge of existing overpassing expressway at point band, anti-throwing net is installed additional, bridge protects at this
Column is combined concrete Bridge guardrail.
For dividing the anti-throwing net of band in bridge, the anti-throwing net of half elliptic is anchored in the width bridge of left and right by the way of crossing over
Divide band in side anti-collision wall guardrail top and covering bridge.The anti-cartouche long axis for throwing net of half-oval shaped is 66cm, short axle
For 40.8cm, braided mesh size 30x40cm, using L50X32X4 angle steel, a pair of and spacing 2m is anchored at concrete anticollision two-by-two
The top of wall.The anti-steel plate support mesh sheet for throwing net in the centre of anchoring angle steel spacing using 50x4 of half-oval shaped.Half elliptic
The anti-steel plate base thrown net anchoring angle steel and be welded on 160x160cm of shape, steel plate base are anchored in concrete using expansion bolt and prevent
Hit wall.Steel plate base anchoring expansion bolt is symmetrically anchored quadrangle at away from steel plate edge 3cm using four M16X120.Welding is anti-
Angle steel, steel plate support and the mesh sheet of junk net soak the preservative treatment measure of modeling using first galvanizing by dipping again, and leaching modeling layer is with a thickness of 0.5
~0.6mm.
Steps are as follows for above-mentioned anti-throwing net installation:
Step 1: carrying out dabbing processing to top concrete on combination guardrail concrete structure top.
Step 2: by being anchored to a thickness of the steel plate base of 8mm with M16x120 expansion bolt having a size of 160cmx160cm
The top surface of concrete structure.
Step 3: good every two meter Wei Yi section of segmentation of the half elliptic anti-throwing net of prefabrication is installed to steel plate base, adopt
It is soldered to steel plate base with L50X32X4 angle steel, wherein angle steel, which is placed, uses route direction 32mm vertical path direction 50mm, electricity
Weldering welded seam length should meet code requirement.
Step 4: steel welding in the adjacent segment angle of fall successively welds completion using back-to-back mode.
Step 5: to all ironwares and carrying out necessary antirust treatment after the completion of welding.To guarantee to assist with ambient enviroment
Tune, anti-throwing mesh sheet and attachment plastic-spraying color and environment are unified.
Example of the invention is explained in detail above in conjunction with embodiment, but the present invention is not limited to examples detailed above,
Within the knowledge of a person skilled in the art, it can also make without departing from the purpose of the present invention
Various change also should be regarded as protection scope of the present invention.
