Description
Technical field
The utility model relates to girder steel and steel roof joist or steel roof truss connected node under a kind of roof natural ventilation, is used for the factory building that the roofing load-carrying members are girder steel or steel roof truss.
Background technology
Roof natural ventilation has been widely used in the factory building of industries such as electric power, metallurgy, chemical industry, most of girder steel or the steel roof truss load-carrying members of adopting of the roofing of these factory buildings.Ventilator and their connection are usually adopted girder steel 1 under the parallel elongated ventilator of twice vertically are being set along factory building under the ventilator bearing, girder steel 1 directly is welded in the steel rest 2 that is located on steel roof joist or the steel roof truss under the ventilator, simultaneously between the girder steel 1 horizontal linking beam 3 is set under corresponding to the twice ventilator at each bearing place, to prevent that cross section, bearing place from twisting and, to see Fig. 1 as lateral-supporting point stressed outside 1 plane of girder steel under the ventilator.So the advantage of way is that girder steel 1 can be pressed linking beam calculating under the ventilator, can reduce the girder steel model effectively, saves steel, and bearing place node processing is simpler simultaneously, is convenient to construction.But there is following problem in this way: 1. owing to girder steel 1 under the ventilator is not only acting on the vertical load that is transmitted by the ventilator bearing, the wind load that acts on simultaneously on the ventilator is finally also passed to girder steel 1 top flange under the ventilator by bearing.This just makes, and girder steel 1 is not only two-way under the ventilator is bent, and is also turned round simultaneously.And only bottom flange and the welding of steel rest of above-mentioned way bearing place, the steel rest only can provide the constraint of bottom flange lateral deformation.Though the top flange is connected with linking beam by stiffening rib, linking beam 3 itself is a kind of elastic restraint the girder steel 1 top flange lateral deformation under the restriction ventilator.So, outside girder steel 1 plane during moment of flexure, Continuous Beam Model does not conform to actual conditions outside the plane of being adopted under calculating ventilator.2. because girder steel 1 is along the vertical elongated setting of factory building under the ventilator, and length is often longer, this just need be provided with many places splicing node, has increased a large amount of welding job amounts, has also improved the requirement to welding quality.3. this way must be provided with horizontal linking beam 3 at the bearing place, when the longitudinal length of factory building is longer, has just strengthened the consumption of steel, has caused certain waste.
Summary of the invention
The utility model is exactly that girder steel and steel roof joist or steel roof truss connected node under a kind of roof natural ventilation are provided in order to address the above problem, purpose is under the prerequisite that computation model is tried one's best with actual conditions conform to of girder steel under ventilator, make support node place more reasonable stress, power transmission clearer and more definite, and reduce rolled steel dosage, convenient construction to greatest extent, thereby reach the purpose that reduces engineering cost.
For reaching girder steel and steel roof joist or steel roof truss connected node under above-mentioned purpose the utility model roof natural ventilation, comprise girder steel under the ventilator, the steel rest that the bottom flange of girder steel is placed on steel rest riser both sides under the ventilator props up on the seat board, steel beam web plate is connected with steel rest top stiffening rib by bolt under the ventilator of steel rest riser both sides, and the top flange of girder steel is connected with steel rest top board by connecting cover plate under the ventilator.
Described steel rest top stiffening rib is located at the steel rest and props up between seat board and the steel rest top board, and two steel rest top stiffening ribs are welded in the both sides of steel rest riser, and two steel rest top stiffening ribs and steel rest prop up seat board and the welding of steel rest top board.
The steel rest of described steel rest riser both sides props up seat board and steel roof joist top flange or steel roof truss and is respectively equipped with steel rest bottom stiffening rib between winding up.
Girder steel is a H shaped steel under the described ventilator.
Described steel rest riser and steel rest bottom stiffening rib and steel roof joist or steel roof truss wind up is connected to continuous fillet weld.
Described steel rest top board and steel rest prop up between the seat board apart from being girder steel height under the ventilator.
Steel roof joist top flange attachment weld adopts continuous fillet weld under described connection cover plate and steel rest top board and the ventilator.
Described steel rest top stiffening rib one end and steel rest riser, steel rest prop up seat board and three welding of steel rest top board, and steel rest top stiffening rib one end is inserted under the ventilator and fixes with the web of girder steel under bolt and the ventilator in the girder steel.
The utility model has the advantages of: being connected between girder steel under the ventilator and the steel rest is approximately rigidity, and steel rest height is generally less, so both the steel rest can be considered as bearing in the plane of girder steel under the ventilator, also can be considered as the plane outer support, calculate so in the plane that girder steel adopted under the ventilator with the plane outside Continuous Beam Model conform to more with actual conditions.Owing to adopted to be rigidly connected, guaranteed the anti-twisting property of girder steel end section under the bearing place ventilator.Comprehensive above-mentioned advantage can not established horizontal linking beam between the two girder steel bearings under ventilator, reduced rolled steel dosage widely, has reduced engineering cost.Simultaneously, adopt this programme can reduce a large amount of steel beam splicing nodes, convenient construction.
The utility model only will be in the past under steel rest in the way and the ventilator connected mode of girder steel adjust, computation model and actual conditions are met more, stressed more reasonable.And reduce rolled steel dosage, convenient construction again to greatest extent, thus reach the purpose that reduces engineering cost, really embodied connection and reasonable arrangement, stressed reasonable, the rational characteristics of materials.
