Description
Technical field
The utility model is related to a kind of prestressing steel strand reinforced concrete girder construction, it is adaptable to building field.
Background technology
When beams of concrete bearing capacity is inadequate, conventional method is utilized in beams of concrete bottom and reinforced using girder steel, this
The method of kind is primarily present following shortcoming：The rigidity of girder steel and beams of concrete is different, in stressing conditions lower girder steel and concrete
The deformation of beam is inconsistent, and girder steel and concrete floor are difficult to cooperate with load.Experiment shows when beams of concrete reaches destruction edge
Girder steel load does not often reach 50%, and the bearing capacity of girder steel plays limited.
Utility model content
The utility model is to provide a kind of prestressing steel strand reinforced concrete girder construction, solves beams of concrete bearing capacity not
Enough the problem of.
In order to improve bearing capacity performance degree of the girder steel in loading process, precompressed is employed to beams of concrete bottom concrete
Technological means, due to beams of concrete, in stress, centre position occurs larger moment of flexure, and centre position beams of concrete is cut
Tension phenomenon occurs in face bottom concrete, and being pulled open easily occurs when upper load constantly increases in the concrete of this position
It is bad, therefore be necessary to set pre- pressure point in this position.Easily occur instead along the position of span direction 1/4 and 3/4 position in addition
Curved, shearing can be very big, sets pre- pressure point that girder steel can be made to participate in stress as early as possible at this position, alleviate significantly beams of concrete by
Power situation.
Girder steel is provided below in beams of concrete in the utility model, and girder steel uses channel-section steel, and cage bar and the girder steel of beams of concrete are welded
Connect, beams of concrete span centre position sets central bearing point steel strand wires, central bearing point steel strand wires are located in the middle part of beams of concrete section, beams of concrete
Pre-punching is set in the middle part of section, and a diameter of 35mm of pre-punching, a diameter of 32mm of central bearing point steel strand wires, central bearing point steel strand wires pass through pre-
Perforation and concrete floor preformed hole are fixed on steel anchoring hoop, and a diameter of 35mm of concrete floor preformed hole is twisted with central bearing point steel
The steel anchoring hoop of line connection is arranged on 600~700mm positions above concrete floor, in order to ensure steel anchors the company of hoop and brick wall
Connect, steel anchors garter spring and arranged around brick wall, steel anchoring hoop cross sectional shape is square, the steel plate thickness of composition steel anchoring hoop for 15~
18mm, width is 120~150mm；Beams of concrete is respectively provided with side fulcrum steel strand wires, side along the position of span direction 1/4 and 3/4 position
Fulcrum steel strand wires are located in the middle part of beams of concrete section, and pre-punching, a diameter of 35mm of pre-punching, side are set in the middle part of beams of concrete section
The a diameter of 32mm of fulcrum steel strand wires, side fulcrum steel strand wires are fixed on steel anchoring hoop through pre-punching and concrete floor preformed hole,
The a diameter of 35mm of concrete floor preformed hole, the steel anchoring hoop coupled with side fulcrum steel strand wires is arranged on above concrete floor
300~400mm positions.
The utility model safe operation is reliable, and structural behaviour is good.
