Description
Technical field
It the utility model is related to box beam technical field, more particularly to a kind of assembly type concrete-filled rectangular steel tube box beam inner membrance.
Background technology
The current bridge prefabrication box beam in the fields such as highway, water conservancy, urban construction, its internal template from traditional rubber pneumatic bag progressively
It is transformed into the rigidity template that sizing makes, for this rigidity inner membrance while globality is preferable, there is also many defects：
1st, high processing costs.
Box beam size (length, width, height), angle in most of design are different from, so the inner membrance ruler of box beam
It is very little also to differ, single steel box-girder inner membrance will be made per bridge block, due to turnover or the duration limitation, will make
Make a few set steel box-girder inner membrances, make new steel box-girder inner membrance, the cost of box beam certainly will be increased.
2nd, reuse, the rate of recovery are low.
After as soon as the prefabricated box -beam of bridge block is completed, the box beam inner membrance mission of this batch of processing finishes.It is otherwise just idle
Get up, otherwise handled as scrap iron.If standby time is too long, by wind and weather solarization, different degrees of rust just occurs
Erosion, the value of recycling are lower.And it is idle for a long time, except occupied space, the expense of also to produce storage, manage etc..
3rd, volume, weight are big, and flexibility is small.
Weight per a piece of box beam inner membrance is all needed from hundreds of kilograms to several tons from the process such as assembling, mobile, dismounting, storage
Lifting equipment is wanted to coordinate, manually or small machine can not operate at all.The flexibility of construction is small, is limited by large lifting equipment
System.
4th, construction, operation difficulty are big.
Box beam steel inner membrance, if the joint number made is more, certainly will produce excessive connector, influences quality；If the length made
Degree is big, causes monolithic quality big, and when dismounting is often limited and long range handling by space, or to wait adjacent beam slab to remove it
After could remove.Extend the turnaround time of box beam, reduce benefit, increase cost.
Sometimes due to film-strength is big in steel, in demolishing process, the cement concrete strength on periphery is relatively low, and steel inner membrance is easy to
The defects of phenomena such as colliding, is damaged is produced to concrete, causes box beam concrete.
Utility model content
The purpose of this utility model is and a kind of group proposed in order to solve to exist in the prior art the shortcomings that inconvenient for use
Dress formula concrete-filled rectangular steel tube box beam inner membrance.
To achieve these goals, the utility model employs following technical solution：
A kind of assembly type concrete-filled rectangular steel tube box beam inner membrance is designed, including base, the both sides of the base vertically connect
Side shield is connected to, inner membrance main body is placed with the base, inner membrance main body includes interior membrane support, the exterior bag of the interior membrane support
Intermediate layer is with, the intermediate layer is the rectangular tube the being parallel to each other composition for being looped around inner membrance bracket outer, the intermediate layer
Outside is surrounded by separation membrane, and the outside of the separation membrane is surrounded with a plurality of plastic-steel belt being parallel to each other.
Preferably, the interior membrane support isThe frame structure that round bar is welded into.
Preferably, the rectangular tube is the galvanized steel rectangular tube of 40mm × 20mm × 3mm, and the corner in the intermediate layer is three
Gusset.
Preferably, connecting seat is equipped with the interior membrane support, a plurality of strut is connected with the connecting seat, the strut
Wherein one end is connected with interior membrane support.
Preferably, support plate, the inner membrance body surfaces and branch are respectively connected between the both sides of the base and side shield
Fagging contacts.
The utility model proposes a kind of assembly type concrete-filled rectangular steel tube box beam inner membrance, beneficial effect is：This practicality
It is new to has the following advantages：
1st, processing is simple：Membrane support in several groups need to only be processed, rectangular tube, the plastics of various specifications that purchase matches it is thin
The equipment such as film, manual plastic steel belt packer.
2nd, processing cost is low, reduces the investment of box beam：Only fixed slot steel bracket, stent reinforcing bar need simple welding,
Processing, significantly reduces processing, cost of transportation.
3rd, high recycling rate, maneuverability are strong：Corresponding form can be assembled into according to the shape difference of interior membrane support
Inner membrance, high recycling rate, maneuverability are strong.
4th, it is good, efficient that operation, flowing water performance are readily produced：Almost all is manual operations, and 1-2 worker just can be real
Apply, process, assemble, being not required large lifting equipment to coordinate in demolishing process, preferable continuous productive process, production efficiency can be formed
It is high.
