Description
Technical field
It is a kind of hollow floor steel girt strip the present invention relates to building element.
Background technology
Using girder steel have the advantages that bearing capacity can be increased in hollow floor.But still suffered from not using middle discovery
Foot.There is structure and owe reasonable in girder steel, the adhesion with concrete is not good enough, simultaneously as when girder steel is combined with concrete, in order to increase
Plus adhesion is exposed outside by the part-structure of girder steel, these exposed parts are also easy to produce corrosion, cause under girder steel overall performance
Drop.Although separately there are several disclosed girder steel configurations, and respectively there is feature, it is not enough more to protrude, the vertical plate of girder steel
Deformity out of plane is easily produced, the song for producing girder steel is bent and can not eliminated, and reduces the load-carrying properties of girder steel, and girder steel is destroyed compared with severe one
Overall structure, so as to reduce the service life of superstructure.This area increases girder steel to solve the problem of girder steel does not produce bent bend
2-3 times of the severe of light plate or increase reinforcement, but these schemes cause the increase of superstructure overall weight, material quantity increases,
Manufacturing cost is significantly increased.The deficiency of these girder steels is also embodied in node point connection, no matter the girder steel of which kind of structure, all nodes
Connection use linear pattern interconnection, the node of these linear pattern interconnections must weld, in construction, again need to be in section
The welding increased at point using steel plate at support strength, these nodes must go to welding slag, apply antirust paint.The section of this welding simultaneously
The error of multiple directions is also easy to produce at point, the load-bearing of girder steel is influenceed, the bulk strength of girder steel is reduced, and then influence the use of superstructure
Life-span etc..
The content of the invention
It is an object of the invention to provide a kind of hollow floor steel girt strip, it can solve the deficiencies in the prior art.
The present invention to achieve the above object, by the following technical programs：A kind of hollow floor steel girt strip, including a plurality of longitudinal direction
Set on steel plate and a plurality of horizontal steel plate, longitudinal steel plate and set several on several the first bent plates mutually rolled over angle, horizontal steel plate
Several second bent plates in the straight panel of several first bent plates on the second bent plate mutually rolled over angle, longitudinal steel plate or horizontal steel plate
Straight panel be mutually coupled respectively, extend along respective rectilinear direction continuity, be respectively equipped with the first bent plate and the second bent plate every
Plate, longitudinal steel plate sentenced with the node that horizontal steel plate intersect in any angle bent plate of a longitudinal steel plate or transverse direction steel plate every
Plate on the basis of plate, straight panel end of the dividing plate both sides respectively with longitudinal steel plate or horizontal steel plate is touched, using bolt by dividing plate and two
Individual straight panel end connection, forms longitudinal steel plate and the intersecting node apparatus of horizontal steel plate four direction.Longitudinal steel plate or horizontal steel
The width two ends of plate are bent out on several wing plates, width of the wing plate relative to longitudinal steel plate or horizontal steel plate respectively
Surface forms the 8th angle α8, steel bar groove is set between each two wing plate, the overbending direction of each two adjacent vanes is opposite.The wing
The 8th angle α that the surface of plate and longitudinal steel plate or the width of horizontal steel plate is formed8For 30o-60o.Divider height direction
Two ends be straight panel, the length direction both sides of every longitudinal steel plate and horizontal steel plate are strip straight panel, the plate of end straight panel
Face and the plate face of strip straight panel are distributed in vertical direction.The node apparatus includes the first bending plate, the second bending plate and the 3rd
The straight panel one end of bending plate, the first bending plate and the second bending plate is arranged in parallel in same level, the 3rd bending plate
Middle part sets the first angle α1With the second angle α2, the first angle α1With the second angle α2Between be dividing plate, the first bending plate it is straight
Plate one end part is in the second angle α2Place, the straight panel one end part of the second bending plate is in the first angle α1Place, dividing plate is respectively with first
The straight panel end of bending plate is parallel with the straight panel end of the second bending plate, and dividing plate, the straight panel end of the first bending plate and second are curved
The straight panel end of folded plate is connected by screw bolts.3rd bending plate is one article of Integral plate type structure.On first bending plate at least provided with
One the 3rd angle α3.At least provided with the 4th angle α on second bending plate7With the 7th angle α6.3rd bending plate
Two ends set the 5th angle α respectively5With the 6th angle α4.The outer end portion of first bending plate, the second bending plate and the 3rd bending plate
Not outwards do not extend.First bent plate（5）With the second bent plate（6）On angle be 90o.The first described angle α1With the second folder
Angle α2Respectively 90o.
The advantage of the invention is that：The structure for the hollow floor steel girt strip that the present invention is provided can thoroughly eliminate the song of girder steel
Bend, the shear(ing) area of concrete can effectively be expanded by being combined with concrete, improve the shearing resistance of armored concrete in hollow floor
Ability.Because the steel girt strip of the present invention is the connection that forms multiple crossover nodes in the same plane by bending steel plate, and respectively
Shear(ing) area is added in the wing plate being bent to form insertion concrete in bending steel plate, makes steel girt strip and reinforcing bar in hollow floor
Resistance to overturning after concrete slab is combined is high, and greatly improves the total quality of concrete slab.It is of the present invention vertical
Longitudinal steel plate and horizontal steel plate and concrete slab and bar-mat reinforcement can be effectively controlled to the end straight panel on steel plate and horizontal steel plate
Position, and then the quality of accurate control integral hollow superstructure.In longitudinal steel plate and horizontal steel plate the end straight panel of 90o bending places with
The perpendicular position distribution in direction of the end straight panel at every longitudinal steel plate or horizontal steel plate two ends, this structure can increase longitudinal direction
The anchor force of steel plate and horizontal steel plate in concrete.The node connection of steel girt strip need not be welded, it is not necessary to be added using steel plate
By force, each node has a whole plate and the straight panel shape steel plate in another two direction to touch, it is only necessary to fasten node using bolt
, the connected mode at node makes steel girt strip not produce the displacement in any one direction, and bonding strength is high, and manufacturing cost is low,
Especially batch production processing, the quality of steel girt strip is that by easily to control.
