Specific embodiment
With reference to the accompanying drawings and detailed description the present invention is described in further detail.A kind of pier cap beam construction
Steel truss support method, comprise the steps:
(1) according to technological requirement, after performance of concrete column confined 1 pours, form preformed hole on performance of concrete column confined 1 top；In concrete
The reserved in the hole of pier stud 1 penetrates rod iron 9；
(2) according to technological requirement, it is symmetrically installed bridle iron 2 at rod iron two ends, lifting platform is symmetrically installed on bridle iron 2 and adjusts
Device 3；Bridle iron 2 is the steel structure support that can bear weight, and lifting platform adjusting means 3 can lift, and relies on pneumatic, liquid
Dynamic or machinery is lifted, to adjust the height of platform；
(3) according to technological requirement, setting in lifting platform adjusting means 3 carries steel girder platform 4, carries steel girder platform 4
It is supported in the lifting platform adjusting means 3 of adjacent two performance of concrete column confined 1；Adjust one or more platform liters as needed
Falling tone regulating device 3 is to adjust the height carrying steel girder platform 4 or levelness；On carrying steel girder platform 4, cushion block 5 is set,
Set shaped steel formwork 6 is installed on cushion block 5, casting concrete then forms the concrete lid of bridge pier in the cavity that set shaped steel formwork 6 is formed
Beam 7.Carrying steel girder platform 4 is the steel structure support that can bear weight, and cushion block 5 is evenly arranged in carrying steel girder platform 4
On, set shaped steel formwork 6 is arranged according to the shape (structure) of the concrete bent cap 7 of bridge pier, pours in the cavity that set shaped steel formwork 6 is formed
Concrete, is met the concrete bent cap 7 of technological requirement after being dried.
The concrete bent cap 7 being formed, after concrete strength reaches, when needing to remove, is carried out: first by the following method
First the left and right being symmetrically installed on bridle iron 2 two lifting platform adjusting means 3 is carried out step-down operation, turns down the height of platform,
So that set shaped steel formwork 6 and concrete bent cap 7 is separated from or loosen；Then, remove set shaped steel formwork according to technological requirement or prior art
6；Preferably, according to the reverse order installed, remove cushion block 5 successively, dismounting carries steel girder platform 4, remove bridle iron 2 and reserved
The rod iron 9 of in the hole.
The lower end of bridle iron 2 is supported on rod iron 9, and matched with the lateral surface of performance of concrete column confined 1 in its side, in order to prevent
Bridle iron 2 produces, and the present invention improves as follows further to bridle iron 2: the riser medial surface of bridle iron 2 and performance of concrete column confined
1 lateral surface is the arc-shaped curved surface coincideing, and mating surface between the two is the arc-shaped curved surface design matching, and can prevent bridle iron
2 inclination, and can be close together；In addition, for guaranteeing bridle iron 2 positioning correcting and the install convenient that couple, bridle iron 2 with
Carried using bridle iron sleeve 8 form between rod iron 9 and design and produce, bridle iron 2 is connected on bridle iron sleeve 8, or steel props up
Cover for seat cylinder 8 and bridle iron 2 make into a single integrated structure (arranging bridle iron sleeve 8 on bridle iron 2), and bridle iron sleeve 8 is enclosed within steel
On rod 9, several steel bushing trip bolt holes 10 are radially designed with bridle iron sleeve 8 simultaneously, in steel bushing trip bolt hole
It is screwed into screw 11, the front end of screw 11, just can bridle iron 2 when mounted and rod iron 9 tight against on the lateral surface of rod iron 9 in 10
Between fastening combine, and the overall cambered design due to riser of bridle iron 2 and bridge pier surface fit tightly anti-incline, formed surely
Fixed, complete steel truss support system.
As shown in Figure 2,3, bridle iron 2 is provided with bridle iron curved plate 12, by bridle iron curved plate 12 and coagulation
Knoll post 1 lateral surface matches, and mating surface between the two is identical arc；Bridle iron sleeve 8 adds under setting steel bushing
Floor 13, bridle iron platform ribbed panel 14, to improve the strength and stiffness of bridle iron sleeve 8, can also prop up in the steel of bridle iron 2
Seat curved plate 12 outer surface setting curved plate ribbed panel 15, to improve its strength and stiffness.
Using steel truss support construction technology and the method for the pier cap beam construction after improving, pier cap beam construction can be shortened
Activity time it is ensured that the quick formation of the steel truss support of pier cap beam construction, improve the working security of support system, real
Stablizing of existing pier cap beam template, ensures the closely knit quality technology effect of bent cap concrete placings.Its technological process is as follows:
(1) erection sequence: 1. performance of concrete column confined 1 pour formation → 2. performance of concrete column confined 1 top reserve in the hole penetrate rod iron 9 →
3. it is symmetrically installed bridle iron 2 at rod iron 9 two ends, bridle iron sleeve 8 → be 4. symmetrically installed lifting platform on bridle iron adjusts dress
Put 3 → 5. install in lifting platform adjusting means 3 and carry the equal cloth pad on carrying steel girder platform 4 of steel girder platform 4 → 6.
The casting concrete of block 5 → 7. install on cushion block 5 set shaped steel formwork 6 → 8. then forms the concrete bent cap 7 of bridge pier.
(2) dismounting order: concrete bent cap 7 concrete strength 1. being formed reaches → 2. to being symmetrically installed on bridle iron
Lifting platform adjusting means 3 is turned down height → 3. remove set shaped steel formwork 6 → 4. remove cushion block 5 → 5. remove and is carried steel truss and puts down
The rod iron 9 of platform 4 → 6. remove bridle iron 2 and reserved in the hole.
A kind of described steel truss support construction technology of pier cap beam construction and method, can shorten pier cap beam construction
Activity time, it is ensured that the quick formation of the steel truss support of pier cap beam construction, improves the working security of support system, realizes
Stablizing of pier cap beam template, ensures the closely knit quality technology effect of bent cap concrete placings.Also dependent on meeting different shape pier stud
Condition and the needs of reserved bearing duct form, enrich existing bridge coping arrangement and method for construction engineering legislation.
Above example only in order to technical scheme to be described and unrestricted, although with reference to preferred embodiment to this
Bright be described in detail, it will be understood by those within the art that, technical scheme can be modified
Or equivalent, the objective without deviating from technical solution of the present invention and scope, it all should cover the claim in the present invention
In the middle of scope.
