Abstract
The utility model provides a kind of two-way large-span prestressed frame beam structure of haunch angle-changing extension, including the first beam, the second beam, floor；First beam intersects with the second beam；First beam, the second beam, floor formed by integrally casting；The equal Horizontal hunche in beam body both sides at first beam and the intersecting end of the second beam；Presstressed reinforcing steel is installed with first beam, the second beam body；The presstressed reinforcing steel is bent upwards at haunch, and top passes at haunch.Prestressed frame girder construction provided by the utility model, is easy to construct, improves operating efficiency.With high strength wire, and the anchorage arrangement caused by tensioning end bar is intensive, prestressed stretch-draw are efficiently solved, pours and the difficulty such as smashes.Using beam-ends haunch plate face angle-changing extension, reduce staying for reserved opening and set and the closure in later stage, it is cost-effective, accelerate the duration.
Description
Technical field
Technical field of building construction is the utility model is related to, specifically a kind of two-way haunch angle-changing extension large span is pre-
Stress frame girder construction.
Background technology
Post-stressed concrete structure can effectively solve the problem that long span building requirement, control concrete cracking, enhancing
The durability of structure.Along with the fast development of China's economic technology, some are used similar to buildings such as warehouse, factory building, cinemas
Post-stressed concrete structure is more and more, and prestressed designing technique, construction technology, quality requirement are also constantly being carried
High and improvement.
Compared to other prestressed structure engineerings, for plane super large, two-way girder is prestressed frame beam, and girder intersects
Joint reinforcing bar sets closeer, and presstressed reinforcing steel is more, and operation requires higher, the installation of bellows and rise control, stretching end and solid
The process difficulty of construction such as the installation of fixed end, the tensioning of steel strand wires are big.Traditional construction method is, in tensioning position Horizontal hunche,
Presstressed reinforcing steel laterally passes tensioning at haunch, this construction method, result in the need for the plate face above haunch position reserve it is larger
Hole, increase difficulty of construction, and tensioning is completed also to block hole, waste of materials and cost of labor.
Utility model content
The purpose of this utility model is to solve to pass structure for the presstressed reinforcing steel of long-span beams in the prior art and lead
A kind of the defects of causing construction technology and tensioning difficulty to increase, there is provided two-way large-span prestressed frame beam structure of haunch angle-changing extension
To solve the above problems.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of two-way large-span prestressed frame beam structure of haunch angle-changing extension, including the first beam, the second beam, floor；Institute
The first beam is stated with the second beam to intersect；First beam, the second beam, floor formed by integrally casting；
The equal Horizontal hunche in beam body both sides at first beam and the intersecting end of the second beam；
Presstressed reinforcing steel is installed with first beam, the second beam body；The presstressed reinforcing steel is bent upwards at haunch, from haunch
Place top passes.
Preferably, the presstressed reinforcing steel from beam body to both sides horizontal curvature while be bent upwards, at haunch
And top passes at haunch.
Preferably, the presstressed reinforcing steel is through in bellows.
Preferably, bleeding hole and grout hole are offered respectively at the crest and trough of the bellows.
Preferably, respectively covered with sponge at bleeding hole and grout hole, covered with plastic cover plate on sponge；The modeling
Expect on cover plate banding fixed bellows；Offer what is connected with bleeding hole and grout hole on the sponge and plastic cover plate
Hole.
Preferably, in the plastic cover plate top plastic tube spreading to setting position.
The utility model compared with prior art, has the advantages that：
Prestressed frame girder construction provided by the utility model, is easy to construct, improves operating efficiency.With high-strength prestressed
Muscle, and efficiently solve the anchorage arrangement caused by tensioning end bar is intensive, prestressed stretch-draw, pour and the difficulty such as smash.
Using beam-ends haunch plate face angle-changing extension, reduce staying for reserved opening and set and the closure in later stage, it is cost-effective, add
The fast duration.
The utility model uses fixes sponge at bleeding hole, grout hole, has good mortar leakage prevention to act on.

Embodiment
The effect of to make to architectural feature of the present utility model and being reached, has a better understanding and awareness, to compared with
Good embodiment and accompanying drawing coordinate detailed description, are described as follows：
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of two-way large-span prestressed frame beam structure of haunch angle-changing extension, including first
Beam 1, the second beam 2, floor 3；First beam 1 intersects with the second beam 2；First beam 1, the second beam 2, the formed by integrally casting of floor 3；
The equal Horizontal hunche 4 in beam body both sides at the intersecting end of the first beam 1 and the second beam 2, the width of haunch 4 and length are according to setting
Count to determine.
Presstressed reinforcing steel 5 is installed with first beam 1, the body of the second beam 2；While presstressed reinforcing steel 5 is from beam body to both sides horizontal curvature
It is bent upwards, hence into top passes at haunch 4 and at haunch 4.
As shown in figure 4, presstressed reinforcing steel 5 is through in bellows 6.Offer and secrete respectively at crest (trough) place of bellows 6
