Description

A kind of T beam pier top continuous segment hogging moment tooth block sealing end mold

Technical field

The present invention relates to T beam pier top continuous segment hogging moment anchor head sealing end field more particularly to a kind of T beam pier top continuous segment are negative Moment of flexure tooth block blocks mold.

Background technique

Tee girder bridge is widely used on various highway bridges, is applied in T beam pier top continuous segment hogging moment tooth block anchor head 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 to anchorage with high grade mortar, 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, finally corrodes, girder pre-stressed to entire T to cause great security-hidden trouble.

Summary of the invention

It is an object of the present invention to provide a kind of T beam pier top continuous segment hogging moment tooth block sealing end mold, the T beam wing is not being damaged In the case where 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 not remaining ironware 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 plate 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 beam pier top continuous segment hogging moment tooth block blocks mould Tool, it mainly includes the first channel steel, the second channel steel, third channel steel, the 4th channel steel, the 5th channel steel and the 6th channel steel, and described first Channel steel and third channel steel are in parallel with the second channel steel side welding in 90 °, and the 4th channel steel and the 5th channel steel are in parallel 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 progress that the present invention has the utility model has the advantages that 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 plate Concrete really outer beauty and interior reality are blocked, hogging moment prestressing force is effectively protected.The sealing end mold has effects that improve, improve The advantages of construction quality, safety and environmental protection and save the cost.
