Description
Technical field
The present invention relates to technical field of bridge construction more particularly to a kind of bridge structure object bottom leakproof sizing device and its apply
Work method.
Background technique
It is more demanding to Structure Appearance Quality in bridge on highway work progress, due to most of works template
Using punching block, often has at form joint or with the position of ground face contact compared with big gap, the matter of works bottom spillage often occur
Common fault is measured, the method for traditional mortar leakage prevention is foam glue closed bottom gap of manually getting blisters, but is connect due to punching block seam crossing or with ground
The position of contact portion position is lower, and when worker operation is unsighted, and needing to squat down checks each position, operates highly inconvenient, Yi Zao
Closing is leaked at contact surface or closes incomplete problem, and so as to cause works bottom spillage, presentation quality is poor after demoulding.And
Manually breaking foamed glue needs to waste a large amount of foam materials, both polluted environment and has also increased construction cost, has extended construction
Time.In consideration of it, need to invent one kind at present and can recycle, the mortar leakage prevention dress of quick closure bridge structure object template bottom
It sets.
Summary of the invention
It is recycled and the bridge of quick closure bridge structure object template bottom the main purpose of the present invention is to provide a kind of
Girder construction object bottom leakproof sizing device and its construction method.
To achieve the above object, the present invention provides a kind of bridge structure object bottom leakproof sizing device, including is fixed on bridge
The length of the fixation device of works two sides and the air bag being installed on fixed device, air bag is greater than or equal to bridge structure object
Length, fixed device are made using channel steel or angle steel.
Preferably, when bridge structure object is bridge prefabrication T beam, air bag uses round balloon, and fixed device is to be fixed on
Channel steel in bar planting.
Preferably, the fixed device is welded using the first channel steel, the second channel steel and third channel steel, the first channel steel,
The end of second channel steel and third channel steel is welded together, and third channel steel and bar planting are welded, and the second channel steel and third channel steel are vertically set
It sets to clamp the side of air bag.
Preferably, the length direction of the third channel steel is provided with takes root in muscle more.
Preferably, when bridge structure object is bridge reinforcement concrete structure guardrail, abutment pier shaft junction or cushion cap and pier
When body junction, air bag uses rectangular air bag, and fixed device is the angle steel for being welded in steel form bottom.
Present invention further propose that a kind of construction method based on above-mentioned bridge structure object bottom leakproof sizing device, including
Following steps:
After bridge structure object template is installed, in bridge structure object template two sides fixing device for installing；
Air bag is coated into release agent close to bridge structure object template side, and is put it into fixed device,
After being inflated to air bag, starts casting concrete, deflate after concrete initial set to air bag and take out air bag to put into
Next bridge structure object template production.
Preferably, when being inflated to air bag, air bag is inflated by air compressor, adjusts air bag angle in the process,
So that air bag has just been filled up gap rear enclosed air bag between fixed device and bridge structure object template, is poured again after inspection is errorless mixed
Solidifying soil.
Bridge structure object proposed by the present invention bottom leakproof sizing device, has the advantages that.
1, using more resilient air bag instead of traditional foamed plastics glue, air bag can be recycled and is used for multiple times,
To save construction material, pollution of the foamed plastics glue to environment is avoided.
2, in bridge structure object template, once inflation can realize all standing to its bottom gap after the installation is completed, when construction
Between it is short, construction efficiency is high, has saved manpower and material resources.
3, fixation balloon is used between gap plugging template, channel steel or angle steel using flexible air bag, position is unbiased
Difference, leak stopping lasting effect is good, effectively prevents the dropping situations that conventional foam glue leak stopping is easy to appear.
4, leakproof sizing device in this bridge structure object bottom can be promoted to all kinds of structures of bridge, for example, bridge cushion cap with
The mortar leakage prevention of ground contact portion, bridge floor anticollision barrier bottom and deck paving border on position mortar leakage prevention, and application range is wider.
