Description
Technical field
The utility model relates to a kind of cold bending thin wall truss-like floor joist for building, the truss-like floor that it adopts cold bending thin wall C Steel section member to form, and it is mainly used in light steel structure house dwelling house field.
Background technology
Housing construction style and form of structure vary, and with regard to the floor slab structure system, several main form of structure such as reinforced concrete structure, wooden construction and steel work are just arranged.Reinforced concrete floor comprises two kinds of cast-in-situ floor and precast floor slabs, though the cast-in-situ floor water proofing property is tight, and long construction period, the cost height, it is cumbersome to construct, and also needs the place.Though precast floor slab is than cast-in-situ floor short construction period, anti seismic efficiency is poor, and a little less than the water proofing property, and flooring can be smooth inadequately.Wooden construction floor slab column system formally by name; timber buildings is with a long history in China; because a variety of causes; well developed after the founding of the state; the modern wood structure building is with its particular performances; in China vast potential for future development is arranged, but be that some modern wood structure building has problems such as sound insulation of wall difference and vibration of floor are big undeniablely, China has also proposed restriction to timber and has made the protection that is used for strengthening to National Environmental recently.Therefore, develop firm durable, building rapidly, the space flexible arrangement, the novel residential structure system that is easy to reconstruct, steel work then becomes the important trend of housing construction and structural development, constantly perfect along with the development in China Real Estate market and building level, the propelling of domestic in addition all kinds of industry internationalization processes, steel house development at home has been trend of the times.
Along with the quick growth of China's output of steel, the development of building material and application, the system of steel residential structure that meets above-mentioned requirements progressively grows up and has caused widely and pays close attention to.
Summary of the invention
In order to overcome the problem that exists in the above-mentioned existing background technology, this use is novel to provide a kind of cold bending thin wall truss-like floor joist for building.It can be used as the ideal substitute of traditional residential structure system, has huge development potentiality.
The purpose of this utility model reaches by following measure: cold bending thin wall truss-like floor joist for building, it is characterized in that it comprises upper chord, lower chord, the end web member, middle web member forms similar equilateral triangle structure between two adjacent middle web members, the angle angle between middle web member and the lower chord is 45 ° to 70 °, described end web member is positioned at the two ends of upper chord and lower chord and is connected upper chord and lower chord, and middle web member is between upper chord and lower chord and connect upper chord and lower chord.
In technique scheme, described end web member or middle web member are connected with a tapping screw at least with each edge of a wing of upper chord or lower chord.
In technique scheme, described upper chord, lower chord, end web member and middle web member are cold bending thin wall C Steel section member, and two V-type grooves that work the effect of putting more energy into are arranged at the three equal parts place of cross section web.
In technique scheme, on described end web member and/or the middle web member web stiffener is arranged, adopt two tapping screws to be connected at least on described web stiffener and end web member or the middle web member.
The utility model cold bending thin wall truss-like for building floor joist adopts the basic component of cold bending thin wall C Steel section member conduct, its configuration aspects have other building types incomparable advantage:
1.: help industrialization, industrialization production.Cold bending thin wall construction steel structure house dwelling house system by cold bending thin wall C formed steel construction 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.
2.: green building, energy saving building.Cold bending thin wall C formed steel construction 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.
3.: improve utilization of space.Owing to adopted light roof and wall body structure, and cold bending thin wall C formed steel construction 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 5-8%.
4.: cold bending thin wall C Steel section member for building, by the connection of tapping screw between rod member, can make different shape, therefore, make design advanced more flexibly, it can finish its building function and art of building characteristic according to designer's wish.
5.: because cold bending thin wall C formed steel construction frame system for building is in light weight, 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.
6.: reduce foundation cost.The deadweight of cold bending thin wall C formed steel construction 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.
7.: 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.
8.: the comprehensive benefit index height.The direct cost of cold bending thin wall C formed steel construction 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.
