Abstract
The invention belongs to the construction structure field, and especially relates to a sectional steel concrete column-steel bar concrete beam joint connection method, which is a novel connection method, aiming to solve the problems of large welding work load and big construction operation difficulty at a joint position of a steel concrete column and a steel bar concrete beam. The sectional steel concrete column-steel bar concrete beam joint connection method comprises an upper flange plate, a lower flange plate, a plurality of vertical bars and a column-shaped steel flange. The advantages are that a vertical plate is narrow, so the stirrup construction at the sectional steel column joint won't be influenced and the arrangement of a pull bar on the beam end won't be influenced by the vertical plate; because the steel bar end is provided with a bent section, the length of the lap joint section is reduced; the length of the upper and the lower flange plates is shortened for transporting conveniently and saving steel material; the connections between the upper and the lower flange plates, the vertical plate and the column-shaped steel flange are finished in a factory; the welding work is free from the construction period, thus the construction is rapid and convenient.
Description
Technical field
The invention belongs to building structure field, particularly a kind of profile steel concrete column-steel concrete girder connection connected mode.
Background technology
At profile steel concrete column-reinforced concrete beam Nodes, when beam indulge muscle be obstructed cannot through also cannot in node concrete when anchoring, reinforcing bar is mainly through welding, overlapping or utilizing several mode of reinforced bar sleeve to be connected with junction plate (steel corbel, short girder steel).But above-mentioned several connected mode, all respectively has shortcoming.Be welded to connect with bracket, by the impact of execute-in-place condition and operator's level, welding quality is difficult to ensure, and labour cost is high.To structure manufacture, Steel Reinforcing Bar Material, position location, sleeve connection requires that precisely, difficulty of construction is large, and affects the duration.And overlapping mode convenient and quick construction, steady quality, but be subject to many limitations in practice.Such as, pillar stirrup need through the web of the short girder steel be connected with shaped steel in post; In concrete beam, lacing wire hinders by steel beam web plate, causes difficulty of construction to increase; Girder steel and lapped length of steel bar longer cause transporting and hoisting difficulty and waste of material.
Summary of the invention
In order to solve, profile steel concrete column and steel concrete beam connecting node place's welding job amount are large, constructing operation difficulty is large and propose a kind of method of attachment adopting the connecting elements that welds with the post edge of a wing and beam longitudinal reinforcement to overlap for object of the present invention.
The technical scheme adopted for realizing the object of the invention is such, a kind of profile steel concrete column-reinforced concrete beam joint connecting method, comprises top flange plate, bottom wing listrium, riser, some vertical muscle and post section steel flange.
Described top flange plate is connected with post section steel flange.The plate face of described top flange plate and plane-parallel.The length direction of described top flange plate is perpendicular to post section steel flange.Described bottom wing listrium is connected with post section steel flange.The plate face of described bottom wing listrium and plane-parallel.The length direction of described bottom wing listrium is perpendicular to post section steel flange.
The upper end of described riser is connected with the lower face of top flange plate.The lower end of described riser is connected with the upper face of bottom wing listrium.The plate face of described riser and horizontal plane.A side of described riser is connected with post section steel flange.
Some described vertical muscle are positioned at the upper and lower plates face of top flange plate and bottom wing listrium.The end of some described vertical muscle is with quarter bend trisection.The bending segment of some described vertical muscle and the surface contact of post section steel flange.The bending segment of some described vertical muscle is all perpendicular to horizontal plane.
What deserves to be explained is, pulling force and pressure are reached upper and lower frange plate by concrete by some described vertical muscle respectively, then pass to section steel flange to node area.Because the concrete thickness at vertical muscle bending segment place is little, the peg on the post edge of a wing can ensure that concrete is not pulled.The shearing of beam is born by concrete and stirrup.
Further, the position of described top flange plate and bottom wing listrium overlaps in vertical direction.
Further, the centre of described top flange plate and bottom wing listrium is gone up along its length and is arranged circular hole all at a certain distance.
Further, the upper face of described top flange plate and the lower face of bottom wing listrium are provided with some outsides peg; The lower face of described top flange plate and the upper face of bottom wing listrium are provided with some inner sides peg.
Further, the bending segment of some described vertical muscle is provided with some post edges of a wing peg in the region that column type steel flange surfaces extends.
Further, the quantity of the vertical muscle of the upper and lower plates EDS maps of described top flange plate is identical and symmetrical about top flange plate; The quantity of the vertical muscle of the upper and lower plates EDS maps of described bottom wing listrium is identical and symmetrical about bottom wing listrium.
Further, the reinforcing bar of some described vertical muscle employing HPB235, HRB335, HRB400 or RRB400 strength grades.
Profile steel concrete column-reinforced concrete beam joint connecting method that the present invention proposes has following advantages:
1, because riser is narrow, the construction of steel column node area stirrup will not hinder by it, and beam-ends lacing wire is arranged also not to be affected by riser.
2, upper and lower frange plate, riser and post section steel flange are welded to connect each other and all complete in factory, and construction stage welding work, quick construction is convenient.
3, because vertical muscle end has bending segment, lap segment length reduces, and the length of upper and lower frange plate is shortened convenient transport and saves steel.
