Transmission column places at the top precast beam, and both ends are connected with the gravity base, and the anti - stand of steel case is installed at gravity base top, and the welding of the anti - stand left end of steel case has the stretch -draw crossbeam, and the space of walking that has broken line prestressing force steel hinge line is reserved to the stretch -draw crossbeam. The anti - stand of steel case stretches into the gravity base and joins as an organic wholely through crab -bolt and gravity base, the anti - stand of steel case adopt the steel construction, the microdilatancy concrete is filled to inside. Transmission column is equipped with a plurality of provided groove mouths, conduct simultaneously according to 2 meters modulus the die block of precast beam. The utility model discloses satisfy multiple elder generation of striding the footpath and open the stretch -draw of broken line prestressing force precast beam, and satisfy multi -disc roof beam prefabricated construction simultaneously, simultaneously the utility model discloses but reuse can effectively reduce the roof beam body and build the cost, save the time limit for a project, guarantee roof beam physique volume and durability.
Description
Technical field
This utility model is related to a kind of precast beam stretching bed seat and in particular to one kind first opens folding prestressed prefabricated girder tensioning
Pedestal.
Background technology
At present, the across footpath of Bridges in Our Country pre-tension prestressed concrete beam is mostly below 20 meters, more than 25 meters of across footpaths
First Zhang Liang does not almost have, and its main cause is that the arrangement of presstressed reinforcing steel adopts straight line Distribution form s, folding prestressed first opens
The construction technology of beam does not also have the technology of maturation.
In recent years, some R＆D institutions also were setting about studying the construction technology of broken line cloth muscle, achieved some achievements, Qinghai-Tibet
Railroad bridge employs 24 meters of broken lines and first opens simply supported beam.But stretching bed seat can only produce a piece of beam, and broken line muscle is at turner
The stress loss producing is larger, and concentrates on turnover at, stretching bed seat is required higher, need to arrange uplift pile and pull out with meeting
The requirement of power is it is more difficult to large scale application.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one kind first to open folding prestressed precast beam and opens
Draw pedestal, solve stretching bed seat and can only produce a piece of beam, the larger problem of the stress loss that broken line muscle produces at turner.
For achieving the above object, this utility model adopts following technical proposals：
One kind first opens folding prestressed precast beam stretching bed seat, horizontal including force-transmitting pole, gravity base, precast beam and tensioning
Beam, described power transmission column top is provided with multiple reserved notches, and precast beam is placed in described power transmission column top.
Described force-transmitting pole two ends are connected with gravity base, and described gravity base top is provided with the anti-column of steel case, institute
The steel case anti-column left end stated is welded with stretch-drawing beam, and what described stretch-drawing beam was reserved with folding prestressed steel hinge line walks sky
Between.
The described anti-column of steel case is stretched into gravity base and is integrated with gravity base link by crab-bolt；Described steel case
Anti- column adopts steel construction, internal perfusion microdilatancy concrete.
Described force-transmitting pole is a kind of axis compression member, using concrete structure；Described force-transmitting pole sets according to 2 meters of modulus
There are multiple reserved notches, described reserved notch is folding prestressed steering gear installation notch；Described force-transmitting pole simultaneously as
The bed die of described precast beam.
Described gravity base is a kind of concrete structure relying on own wt to offset moment of flexure caused by prestressed stretch-draw, and with
Described force-transmitting pole connects as one.
The anti-column of two steel casees is had on described gravity base.
The beneficial effects of the utility model：
This utility model meets the tensioning first opening folding prestressed precast beam, be assume responsibility for folding prestressed by gravity base
The larger moment of flexure that stretching force causes, reserves installation notch in power transmission column top and meets the need first opening folding prestressed steering
Ask, notch is pressed modulus and reserved, and can meet multiple across footpaths first opens folding prestressed prefabricated girder tensioning, and can meet multi-disc beam simultaneously
Prefabricated construction, this utility model is repeatable simultaneously utilizes, and can effectively reduce beam body construction costs, saves the duration, ensures beam body matter
Amount and durability.
