Description
Technical field
The present invention relates to building structure technology field, be specifically related to a kind of corrugated web deck-molding utilization rate circle accessory that punches.
Background technology
Corrugated web girder steel is that steel web is processed into periodically trapezoidal, fold-line-shaped or curved along beam span direction.Compare with traditional girder steel, corrugated web girder steel has plurality of advantages, because corrugated steel web local stability improves greatly, so can reduce web thickness, compare with the tradition flat steel web of putting more energy into, under identical shear resistant capacity condition, corrugated web girder steel than traditional flat web girder steel from important reduction by 30%.Corrugated steel web can be avoided the too early flexing phenomenon being caused by geometrical defect to a certain extent simultaneously, because it is very little that the degree of depth of corrugated steel web thickness defect and corrugated steel web folding groove or wave height are compared, so the sensitivity of corrugated steel web thickness defect is also reduced greatly.Corrugated steel web has also improved the anti-surrender ability of flange of beam, has strengthened lateral bending rigidity and the stability of web, the fatigue life of having improved beam.Meanwhile, the waveform outward appearance of its web of corrugated web girder steel has good building sight.
Extremely strong anti-shearing flexion capabilities, the unique advantage of corrugated web web makes it in the larger building of span, have a lot of application.But because the cross section of beam is higher, in order effectively to improve the usage space of building, main equipment pipeline need to pass web conventionally, and this just need to punch on the web of corrugated web beam.
When large dimension lines must laterally run through ripple web beam, need be on its web opening holes, because the more flat web of corrugated web is thin, after large scale punches, must consider the reinforcement measure of its web.
Summary of the invention
The present invention proposes a kind of corrugated web deck-molding utilization rate circle accessory that punches, by to the punching of corrugated web girder steel, can make pipeline pass from web, improved architectural space utilization rate, part arranges the thickening of stiffening rib and local web, reaches the stress concentration phenomenon after avoiding punching greatly.
The technical solution used in the present invention is: a kind of corrugated web deck-molding utilization rate circle accessory that punches, comprises top flange steel plate, bottom flange steel plate, circle punch flat web, the pipe that punches, short stiffener and junction plate;
Between described top flange steel plate and bottom flange steel plate, be provided with the circle flat web that punches, wherein the circular periphery punching is provided with the pipe that punches, punch two sides of flat web of described rectangle are equipped with junction plate, described punching is provided with horizontal short stiffener between pipe and junction plate, and described junction plate is connected with the junction plate of corrugated web beam by bolt;
Described circle punches between each parts of accessory all by being welded to connect.
As preferably, punch two jiaos of the long side directions of flat web of described circle need cut welding corner cut by < < Code for design of steel structures > > GB5007-2003 regulation.
As preferably, the described circle accessory that punches is used steel consistent with corrugated web beam wood property.The concrete size of the present invention need be arranged according to the concrete size of structural element by structural engineer.
The overhanging size of junction plate of the present invention and bolt arrangement and number needs are arranged according to concrete structure by Structural Engineering.When pipeline need to be when the corrugated web beam, structural engineer can arrange the corresponding corrugated web deck-molding utilization rate circle accessory that punches according to pipeline desired location and size and be connected with corrugated web beam, and formation can be worn the new-type corrugated web beam of required pipeline.The described corrugated web beam circle accessory that punches is connected by high-strength bolt with corrugated web beam junction plate, is combined into the punch beam of accessory of corrugated web beam and arranges at building assigned address.By the design of horizontal and vertical stiffening rib, meet its bearing capacity and stability.
Beneficial effect: the present invention realizes punching of corrugated web web by stiffening rib is set, for the use of corrugated web has later brought wider application prospect, it is a kind of equipment installation arrangement that can effectively improve space availability ratio, substantially do not changing under the stress performance of corrugated web girder steel and the basis of deflection deformation, having solved the floor height causing because pipeline arranges reduces, space wasting phenomenon, makes pipeline be able to flexible arrangement, has increased the attractive in appearance of architectural space.
Accompanying drawing explanation
Fig. 1 is the circle of the present invention accessory structure schematic diagram that punches;
Fig. 2 is the circle of the present invention accessory scheme of installation that punches.
The specific embodiment
Below in conjunction with the specific embodiment and accompanying drawing, the present invention will be further described:
As illustrated in fig. 1 and 2, a kind of corrugated web deck-molding utilization rate circle accessory that punches, comprises top flange steel plate 1, bottom flange steel plate 2, circle punch flat web 3, the pipe 4 that punches, short stiffener 5 and junction plate 6;
Between described top flange steel plate 1 and bottom flange steel plate 2, be provided with the circle flat web 3 that punches, wherein the circular periphery punching is provided with the pipe 4 that punches, punch two sides of flat web 3 of described rectangle are equipped with junction plate 6, described punch to be provided with between pipe 4 and junction plate 6 horizontal shortly put more energy into 5, described junction plate 6 is connected with the junction plate 7 of corrugated web beam 9 by high-strength bolt 8;
Described circle punches between each parts of accessory all by being welded to connect.
Punch two jiaos of the long side direction of flat web 3 and two jiaos of corrugated web beam junction plate end webs of described circle need cut welding corner cut 10 by < < Code for design of steel structures > > GB5007-2003 regulation.The described circle accessory that punches is used steel consistent with corrugated web beam wood property.
Water-feeding drainaging line and HVAC pipeline, in the time must laterally running through ripple web beam, punch, under the effect of uniform load in the middle of the web of beam, consider the smallest point place of shearing and moment, apart from beam-ends approximately 1/3 place, punching, the shape that punches, depending on institute's drawing-in wire, is got circle.At the web place that punches, consider that on cross section, the web place of punching, action moment is born by the edge of a wing, to web, adopt the steel that equate with strength of parent grade to strengthen, shearing is by the web that punches, reinforcement stiffening rib and thicken local web shared, the section area sum of the web at the place of punching and stiffening plate is greater than the section area of former web, and concrete size is determined according to selected girder steel size by engineer.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
