[specific embodiment]
Below in conjunction with accompanying drawing better embodiment of the present utility model is elaborated.
See also Fig. 1, the utility model is a cold bending thin wall type combined girder steel for building, and it comprises steel web 1, wind up 2, lower edge 3 and screw 4.In the illustrated embodiment, steel web 1 is a thin steel sheet, winds up 2 to be the double C shape cross section, and lower edge 3 is the double C shape cross section, winds up 2 to be fixed on the upper limb and the lower edge of steel web 1 respectively by two row's screws 4 with lower edge 3.Winding up 2 comprises left boom plate 22, goes up right boom plate 24, goes up that left boom plate 22 is respectively C tee section steel member with last right boom plate 24 and is that axis is symmetrical arranged with steel web 1.Lower edge 3 comprises bottom left boom plate 32, bottom right boom plate 34, and bottom left boom plate 32 is respectively C tee section steel member with bottom right boom plate 34 and is that axis is symmetrical arranged with steel web 1.For ease of carrying with deposit, screw 4 can adopt the self-taped type screw, steel web 1 with wind up 2, lower edge 3 can assemble at the construction field (site), can be adapted to various industrial and minerals scene.
In the illustrated embodiment, steel web 1 can be zinc-plated flat board, and its height H is 400mm, and its thickness D is greater than 1.15mm.The double C shape cross section wind up 2 and double C shape lower edge 3 between spacing L be 120mm, fixedly wind up 2 or the spacing 1 of two rows between the screws 4 of lower edge 3 less than 30mm.
Please in conjunction with consulting Fig. 2 and Fig. 3, because last left boom plate 22, last right boom plate 24, bottom left boom plate 32, bottom right boom plate 34 are cold bending thin wall C shape steel member, its wall thickness d is 0.75mm in the illustrated embodiment, for strengthening the intensity of C shape steel member, two V-type grooves 5 (as shown in Figure 2) that work the effect of putting more energy into can be set at the three equal parts place of its vertical plate respectively.Equally, also can stiffener 6 be set in the vertical plate and the transverse plate junction of C shape steel member.
See also Fig. 4, the schematic diagram that it is connected with bracing frame 10 for the utility model combined girder steel.In the application scenario of Fig. 4, the lower edge 3 of combined girder steel serves as ceiling to be used.
See also Fig. 5, it is the connection diagram of the utility model combination joist steel and wall frame 20.Combined girder steel uses as the house top support structure, combined girder steel wind up 2 as roof panel, the lower edge 3 of combined girder steel is as the furred ceiling beam.
See also Fig. 6 and Fig. 7, it is the schematic diagram of the bracing frame of employing the utility model combined girder steel.Combined girder steel is used in combination with wall trestle 30 and ceiling 40.The deck-molding of combined girder steel can be undertaken by the height that changes steel web 1 according to using needs.
The utility model combined girder steel adopts the basic component of cold bending thin wall C shape steel member conduct, its configuration aspects have other building types incomparable advantage:
One, helps industrialization, industrialization production.Cold bending thin wall construction steel structure house dwelling house system by cold bending thin wall C shape steel work prefabricated units for building (frame sheet, net sheet etc.) and match with it safeguard what wallboard, door, window, partition etc. were formed, therefore satisfy the industrialization typing and produced the characteristics of on-site consolidation.
Two, green building, energy saving building.Cold bending thin wall C shape steel structure frame system for building, environmental disruption and pollute few, reconstruction and remove easily the recyclable and regeneration rate height of material.Therefore, this structural system has reached the requirement of green building, adopts the light material of its supporting technology simultaneously, meets the requirement of energy saving building more.
Three, improve utilization of space.Owing to adopted light roof and wall body structure, and cold bending thin wall C shape steel structure frame system for building is as the strength of materials height of its support steel structure, and materials are economized, and are small, so from heavy and light.So when doing support system with steel work, can build the standard width of a room in an old-style house, depth is bigger, the indoor dwelling house of not establishing the flexible separation of post of house type satisfies the requirement of architectural plane function; Can improve simultaneously the space availability ratio of dwelling house, be suitable for the transformation of the vertical moral interlayer of dwelling house, local staggered floor.And the cross section of required member is little, and the architectural space utilization rate under identical building area increases by 5%～8%.
Four, cold bending thin wall C shape steel member for building by the connection of tapping screw between rod member, can be made different shape, therefore, makes design advanced more flexibly, and it can finish its building function and art of building characteristic according to designer's wish.
Five, because cold bending thin wall C shape steel structure frame system weight for building is light, volume is little, and steel work itself has good ductility, so the situation analysis of the antidetonation of its steel house destruction, and this type of structural construction obviously is better than brick mix structure and reinforced concrete frame structure.
Six, reduce foundation cost.The deadweight of cold bending thin wall C shape steel structure frame system for building is lighter, and foundation load also reduces accordingly, has therefore reduced the difficulty of construction and the cost of Foundation Design.
Seven, short construction period, the returns of investment of raising fund, job site civilization.Except that foundation construction; member is all by professional factory normalization production; speed of application is fast; construction period shortens half than traditional architecture; each parts transports assembled on site to; job site civilization situ wet operation is few; noise dust and building waste are also few; satisfy requirement on environmental protection, construction operation is subjected to weather and seasonal effect less (winter can at produce in factory steel member), and can produce in factory and on-the-spot parallel carrying out be installed; even some standardized dwelling house systems; can with construction, shorten construction period and occupation of capital time greatly with order.
Eight, comprehensive benefit index height.The direct cost of cold bending thin wall C shape steel structure frame system dwelling house for building is a little more than concrete structure about about 5%.But its economic benefit, social benefit height, in today of real estate enterprise keen competition, it is the concentrated reflection of real estate enterprise comprehensive strength, for improving the enterprise product brand, the social popularity that improves enterprise all has bigger influence.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
