According to the structure provided by the utility model, through applying force to the arch steel plates, a reverse torque opposite to the bearing load is applied to the I-shaped steel beam, the deformation and the stress of the I-shaped steel beam are relieved; the reinforced-type I-shaped beam structure is good in integral intensity, is simple and reasonable in structure, and has a favorable technical economical benefit.

Description

A kind of reinforced steel I-beam structure
Technical field
The utility model relates to a kind of i shaped steel girder construction, particularly relates to a kind of reinforced i shaped steel girder construction with arch-shaped steel plate simple in structure.Belong to the structural steelwork field, the i-shape steel beam that is applicable to high level and large span architecture is strengthened structure.
Background technology
The i iron i iron is a kind of economical section steel of section good mechanical performance, and the wide lateral rigidity in its edge of a wing is large, and bending resistance is strong, is widely used in various building structure, bridge, vehicle, support, machinery etc.Two surfaces, the edge of a wing are parallel to each other and make connection, processing, easy for installation.With normal section steel, compare, cost is low, and precision is high, and residual stress is little, without expensive welding material and weld seam detection, saves structure steel fabrication cost 30% left and right.With concrete structure, compare, i-beam structure can increase 6% usable floor area, and dead load alleviates 20%-30%, reduces structure design internal force.
Girder steel has a wide range of applications in industry and civilian construction.In field of house buildings, girder steel is mainly used in building roof beam, the working platform beam in factory, crane girder in multilayer and high-story house, wall is set a roof beam in place and roof system in purlin etc.At other civil construction field girder steels, also have a wide range of applications, as various Longspan Bridges, the steel gate in hydro-structure etc.Steel work is compared with widely used reinforced concrete structure in building structure, has the cross section profile size little, the gentle thin characteristics of the elongated and plate of member.Steel work can be subject to the erosion of natural environment, the effect of external loads or the destruction of human factor in running, therefore inevitably can have various defects and damage.Now, need be strengthened girder steel element.
The main method of existing reinforced steel beam and girder is to utilize the easily characteristics of welding of girder steel, at span centre, lateral support is set or strengthens the edge of a wing of original member and web thickness etc.The former,, by intermediate stiffener being set at the steel I-beam span centre or supporting stiffening rib, arranges more stiffening rib welding procedure difficulty larger, and steel I-beam also tool is had a certain impact, and consumptive material is more; Latter is not suitable for the situation that loads change is larger.
In sum, along with steel beam structure is employed more and more in construction work, for solving the problems such as current girder steel bulk strength is low, support degree is low, need badly at present a kind of good integral strength of invention, simple in structure, do not waste raw material, with the reinforced i shaped steel girder construction of arch-shaped steel plate.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model be to provide a kind of good integral strength, simple in structure, do not waste raw material, with the reinforced i shaped steel girder construction of arch-shaped steel plate.
In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:
A kind of reinforced i shaped steel girder construction, arrange " L " shape drag plate at i shaped steel web place; Arrange arch-shaped steel plate between two drag plates that are oppositely arranged and i-shape steel beam top flange, the arch-shaped steel plate top is connected by screw rod with top flange, and two ends are placed on the drag plate.
The quantity of arch-shaped steel plate is more than 1 or 1, uniformly-spaced is laid in symmetrically i shaped steel web both sides.
The drag plate is preset the bolt spacing hole, drag plate one end and the welding of i shaped steel web, and the other end and i-shape steel beam bottom flange are fixed by screw rod.
At drag plate and arch-shaped steel plate fixed end, square baffle plate also is set.
The utlity model has following characteristics and beneficial effect:
(1) the drag plate is " L " type, an end and the welding of i shaped steel web, and an end firmly is connected by screw rod with the i-shape steel beam bottom flange.The drag plate is the position of arch-shaped steel plate fixedly, also can play the effect of transverse stiffener.
(2) the arch-shaped steel plate center is connected by screw rod with the i-shape steel beam top flange, and end and drag plate join, and the baffle plate arranged on the drag plate can avoid arch-shaped steel plate the problems such as inclination, skew to occur in work progress.
(3) arch-shaped steel plate applies an opposing torque contrary with its bearing load by the combinations thereof way to i-shape steel beam, with the distortion that alleviates i-shape steel beam and stressed.
The accompanying drawing explanation
Fig. 1 is the structural representation of the reinforced i-shape steel beam of the utility model.
In figure: 1-web, 2-top flange, 3-bottom flange, 4-hold-down nut, 5-screw rod, 6-drag plate, 7-baffle plate, 8-arch-shaped steel plate, 9-drag plate set bolt, 10-i-shape steel beam.
The specific embodiment
The welding procedure of i-shape steel beam and drag plate, arch-shaped steel plate, the screw rod of arch-shaped steel plate are connected in the present embodiment such as technique and are not repeated, and specifically set forth the embodiment that the utility model relates to structure.
Fig. 1 is the structural representation of the reinforced steel I-beam of the utility model.
Shown in Fig. 1, a kind of reinforced i shaped steel girder construction, mainly be comprised of i-shape steel beam 10, arch-shaped steel plate 8, drag plate 6, baffle plate 7.I-shape steel beam 10 is comprised of web 1, top flange 2, bottom flange 3, i-shape steel beam 10 adopts the common i iron of hot rolling, for 360mm, width, is highly that 136mm, waist thickness are 10mm, the average thick 15.8mm of leg, inner arc radius 12.0mm, leg end arc radius 6.0mm.At steel I-beam web 1 place, " L " shape drag plate 6 is set, between drag plate 6, on arch-shaped steel plate 8 is set between bottom flange, and on an end of the drag plate 6 of being close to bottom flange 3, fixed dam 7 is set.
