The side column beam comprises a stand column and cross beams, the cross beams are fixedly arranged at one side of the stand column by flange plates in a threaded mode, and cable-stayed beams are arranged between one side of the upper and lower ends of the stand columns by the flange plates in a threaded mode. Due to the fact that a connecting way of combining the columns and the cross beams, square bars, and triangle supports respectively added at the upper portion and lower portion of the joint part of the stand columns and cross beams are used by the steel structure building column beam, compared with an H-shaped steel and concrete structure, the steel structure building column beam has the obvious advantages that the structure is reasonable, the anti-earthquake performance is good, standardized mass production of a factory is convenient, construction is easy, the mounting is quick, good docility and toughness are supplied and wide application to high-rise steel structure building can be achieved.
Description
Technical field
The utility model relates to building material technical field, is specifically related to a kind of steel building post beam.
Background technology
Iron and steel is compared with traditional constructional materials higher mechanical strength and toughness, also has the properties such as heat-resisting, corrosion-resistant, wear-resisting.Country's building trade has steel work and two kinds of selections of concrete structure, and for heavy construction, steel work is undoubtedly optimal selection.Concrete structure material will become building waste after 50 years, steel work but can be recovered utilization, add the advantages such as weight ratio is reasonable, anti-seismic performance good, can weld, sealing is strong, today large-scale steel structure engineering very flourishing in industry often has the huge market advantage than conventional concrete structure.
The national policy advantage: employed raw material all meet national low-carbon (LC) and energy-conservation requirement in the large-scale steel structure engineering, are real 21st century green buildings.
The raw material advantage: along with China's iron and steel output occupies first place in the world, country begins to promote, supports to use steel, and has set up and united the steel group that uses.Steel building industry steel using amount is large, and China's steel building industry is always flourish in recent years, and this has promoted the development of steel work raw material to a certain extent.
In addition, because land resources is non-renewable, the Ministry of Construction has ordered to ban use of traditional loam brick, and adopt the steel house of novel wall material can improve energy-saving efficiency 50%, increase effective usable floor area 6% to 8%, save construction water, but reduction of erection time also is one of best residence form of realizing the energy and land saving target.The related industry policy that meets China's energy-conserving and environment-protective, meet propose in China's Eleventh Five-Year Plan " developing a circular economy, is the important channel of building a resource-conserving and environment-friendly society and realizing sustainable development.Therefore, the development of steel work industry has obtained all the time the great attention of relevant government department and has supported energetically, and relevant technical policy and standard criterion also are further improved.Explicitly point out in China's steel work industry Eleventh Five-Year Development Plan planning: enlarge the proportion of steel work in construction project, strive that to 2010 the proportion of national construction steel structure in construction work investment cost total amount expands 20% to from 10%; Devoting Major Efforts To Developing and development new technology make the industry be in the status of technological precedence in the whole nation; Aspect process equipment, development, popularization manipulator weld knot equipment, guarantee the welding quality of special engineering, by the production domesticization of new material, new equipment, reduce cost, the promoting enterprise technology innovation.
In all kinds of steel work, Elements of Space Grid Truss is with its diversified outward appearance, good antidetonation, tensile structure, stable physics ability to bear, be applicable to heavy construction, such as sports palace, high building etc., the Elements of Space Grid Truss building occupies an important position in China urban municipal construction.2010, national steel structural construction engineering surpassed 4000, and wherein the Elements of Space Grid Truss building surpasses 2000, and the demand of Elements of Space Grid Truss is constantly soaring.The whole world is so far in the completed 101 building super highrise buildings, reinforced concrete structure Building 16, pure steel structure Building 59; Its comprehensive cost is not high, and shock resistance is good.
At present, the high-rise building steel structure beam column connects the general following several types of attachment that adopt: the one, and all-weld joint, the 2nd, high-strength bolt mixes with welding and is connected, the 3rd, by the high-strength bolt connection of T-shaped connector, domestic and international many scientific research structures have been carried out experimental study to above-mentioned three kinds of multi-form switching performances, think: make good all-weld joint point under loading effect repeatedly, the node ability to bear does not reduce, load one amount of deflection hysteresis loop is stable spindle, connects to have good ductility.But difficulty of construction is large, and progress is slow, and the Site Welding quality is not allowed to guarantee; Weld fully on the second type of attachment flange of beam and the post edge of a wing, web is connected with post with high-strength bolt, with the next time repetition of line of iso-deflection, expression is through after repeatedly loading, the node supporting capacity does not also reduce, but this type of attachment through repeatedly very violent complete solid repeatedly after, suddenly fracture, show to be connected the ductility that has with pillar web this to have ductility than the all-weld joint node slightly poor, also can satisfy the desired ductility of earthquake resistant engineering but the bolt weldering mixes tie point; The third connection can be simplified manufacturing and convenient the installation, but is subjected to the impact of T-steel and high-strength bolt performance larger, does not sometimes reach rigidly connected requirement.
Summary of the invention
The purpose of this utility model provides a kind of steel building post beam, and this steel building post girder construction is reasonable, and intensity is high, and shock resistance is good, is convenient to factory normalization production, and is easy for installation.
For achieving the above object, the technical solution of the utility model is: a kind of steel building post beam comprises intermediolateral column beam and side column beam, described intermediolateral column beam comprises column and crossbeam, crossbeam is spirally connected through the flange symmetry and is fixedly installed on the column, connect through the farad valve snail respectively between column upper and lower side both sides and crossbeam and be fixedly installed the oblique pull beam, described side column beam comprises column and crossbeam, crossbeam is spirally connected through flange and is fixedly installed on a side of column, and being spirally connected through flange respectively between column upper and lower side one side and crossbeam is fixedly installed the oblique pull beam.
