Description
Technical field
The utility model relates to a kind of cable channel, is specifically related to a kind of middle span, under identical stressing conditions, can save the H-shaped steel of corrugated web cable channel of steel using amount.
Background technology
Cable channel is a kind of in order to cabling, sets up skyborne channel design.When span is less, Corridor generally adopts H profile steel girder steel; When span reaches 15m and be above, Corridor generally adopts steel truss structure form.
The H profile steel that architectural shape uses is a kind of section area allocation optimized, the rational high efficiency section bar of the ratio of strength to weight, all have that bending resistance is strong, the advantages such as simple, cost-saving and lightweight construction of constructing in all directions, oneself is widely used heavy construction and bridge, boats and ships, handling machinery, equipment Foundations etc.At present what adopt is hot rolled H-shaped, welded H section steel and hot rolling i iron more.Wherein, hot rolling i iron and hot rolled H-shaped shaping in factory, by the restriction of various technical condition, web is necessary for module extender board, and ratio of height to thickness is thinner.There is not cripling in welded H section steel beam, web ratio of height to thickness can not be excessive before ensureing surrender, so need the stability strengthening web by arranging the measures such as stiffening rib, and welded H section steel many employings dihedral weld seam, welding capacity is large.The weak points such as in sum, common shaped steel at stress form comparatively reasonably simultaneously, also has flexing as easy in web, and during stability requirement height steel using amount is large.
Utility model content
For the problems referred to above, main purpose of the present utility model is to provide a kind of middle span, under identical stressing conditions, can save the H-shaped steel of corrugated web cable channel of steel using amount.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of H-shaped steel of corrugated web cable channel, it is characterized in that: described cable channel comprises H-shaped steel of corrugated web girder steel, flat web H shaped steel steel column, bracing members, junction plate and gusset plate, steel column and H-shaped steel of corrugated web are by being connected as a single entity with junction plate welding (or hinged), bracing members is welded on gusset plate, described H-shaped steel of corrugated web comprises upper flat plate, lower flat board and middle Corrugated webs, described upper flat plate and lower platen parallel, middle Corrugated webs is perpendicular to upper flat plate and lower flat board and between upper flat plate and lower flat board, middle Corrugated webs presents the setback shape of periodically repeating along its length.
In specific embodiment of the present utility model, the distance range between two steel columns that described H-shaped steel of corrugated web cable channel is adjacent is 15 meters-20 meters.
In specific embodiment of the present utility model, in described H-shaped steel of corrugated web, cross section is trapezoidal, and end cross-sectional is straight line, and when adopting hinged, this straight line web place, end is provided with installing hole.
Positive progressive effect of the present utility model is: the longitudinal girder of cable channel of the present utility model adopts H-shaped steel of corrugated web beam.Economic span of the present utility model is generally 15m ~ 20m, and beam-ends can be designed to hinged or consolidation, installs node complicated unlike common H profile steel beam.
The utility model is owing to have employed H-shaped steel of corrugated web beam, and under the prerequisite not using stiffening rib, web adopts steel sheet can obtain higher out of plane stiffness and intensity, and Out-of-plane Stability is obviously better than common H profile steel beam.Under identical force-bearing situation, can save girder steel using amount, and reduce secondary beam quantity, economic benefit is very remarkable.
The utility model according to the outer different designs load condition of plane, by adjusting typical setback shape and web thickness, can also meet the needs of different stressing conditions outside structural plan.
