Description
Technical field
The present invention relates to T beam pier top continuous segment hogging moment anchor heads sealing end field more particularly to a kind of T beams pier top continuous segment are negative
Moment of flexure tooth block blocks mold.
Background technology
Tee girder bridge is widely used on various highway bridges, is applied in T beam pier top continuous segment hogging moment tooth block anchor heads sealing end
In working hour, the sealing end of hogging moment tooth block becomes a great problem in construction on the outside of side bar.Generally mould is installed using tooth block structure reinforcing bar
Plate sealing off and covering anchorage directly carries out package processing with high grade mortar to anchorage, the former can retain reinforcing bar, shape in tooth block protection layer
At steel bar corrosion channel；The latter under the dynamic load repeated action after being open to traffic, tooth block sealing end mortar can gradually fall off, cause anchorage and
Steel strand wires head is exposed, last corrosion, girder pre-stressed to entire T to cause great security-hidden trouble.
Invention content
The purpose of the present invention is not damaging the T beam wings to provide a kind of T beams pier top continuous segment hogging moment tooth block sealing end mold
In the case of listrium and hogging moment tooth block concrete, hogging moment tooth block sealing end template is fixed using channel steel and screw rod, anchor is perfused
Head concrete solves the problems, such as security-hidden trouble existing for conventional end blocking method.Before ironware not being remained in structure protective layer
It puts, realizes the fixation of hogging moment tooth block template, by staying the filling for setting embedded hole and carrying out sealing end concrete on T beam flange plates
Note keeps hogging moment sealing end concrete really outer beautiful and interior reality, is effectively protected hogging moment prestressing force.
To achieve the above object, the technical scheme is that：A kind of T beams pier top continuous segment hogging moment tooth block sealing end mould
Tool, it mainly include the first channel steel, the second channel steel, third channel steel, the 4th channel steel, the 5th channel steel and the 6th channel steel, described first
Channel steel and third channel steel are parallelly with the second channel steel side welding in 90 °, and the 4th channel steel and the 5th channel steel are parallelly with the
Three channel steel bottom welding in 90 °, the 6th channel steel are vertically welded with third channel steel, first channel steel, third channel steel, the
It opens up grooved hole on the web of four channel steels, the 5th channel steel and the 6th channel steel, is welded in the slot and is worn for screw rod
Nut, screw rod one end on the third channel steel, the 4th channel steel, the 5th channel steel and the 6th channel steel is equipped with nut, the other end is equipped with
Steel plate, screw rod one end on first channel steel is equipped with two Ribbed Bars, the other end is equipped with steel plate, and the 6th channel steel bottom is logical
Two Ribbed Bars are crossed to be fixedly connected with the 4th channel steel, the 5th channel steel respectively.
Further, first channel steel, the second channel steel, third channel steel, the 4th channel steel, the 5th channel steel are generally aligned in the same plane
Interior, the 6th channel steel is perpendicular to the plane.
Further, first channel steel, the second channel steel, be also welded with stiffened steel plates on third channel steel.
The actively progressive advantageous effect that the present invention has：Under the premise of not remaining ironware in structure protective layer, realize
The fixation of hogging moment tooth block template makes hogging moment by staying the perfusion for setting embedded hole and carrying out sealing end concrete on T beam flange plates
It blocks that concrete is really outer beautiful and interior reality, is effectively protected hogging moment prestressing force.The sealing end mold has effects that improve, improve
Construction quality, safety and environmental protection and cost-effective advantage.
