Description
Technical field
The utility model belongs to light steel structure house house field, is specifically related to the structure of a kind of house roof truss, says more specifically a kind of cold bending thin wall arched roof truss for building.
Background technology
Housing construction style and form of structure vary, and with regard to the structural system of house roof truss, just have several main form of structure such as reinforced concrete structure, wooden construction and steel work.
The house roof truss of reinforced concrete structure comprises two kinds of cast-in-situ floor and precast floor slabs, although cast-in-situ floor water proofing property is tight, and long construction period, cost is high, constructs loaded down with trivial details, also needs place.Although precast floor slab is than cast-in-situ floor short construction period, anti seismic efficiency is poor, and a little less than water proofing property, and flooring can be smooth not.
Wooden construction floor is also referred to as slab column system; timber buildings is with a long history in China; due to a variety of causes; well developed after the founding of the state; Modern Wood Construction is with its unique performance; have vast potential for future development in China, but be that some Modern Wood Constructions have the problems such as the poor and vibration of floor of sound insulation of wall is large undeniablely, China has also proposed restriction to timber and has made for strengthening the protection to National Environmental recently.
Steel house is firm durable because having, building rapidly, the feature of space flexible arrangement, therefore steel house has become the important trend of housing construction and structural development, constantly perfect along with the development in China Real Estate market and building level, in addition the propelling of domestic all kinds of industry internationalization processes, steel house development has at home been trend of the times.
Along with the rapid growth of China's output of steel, and the development of building material and application, the light gauge cold-formed steel shape structure dwelling house system that meets above-mentioned requirements progressively grows up and has caused widely and pays close attention to.
In light gauge cold-formed steel shape structure dwelling house system, cold bending thin wall type roof truss is in order to improve the mechanical performance (as intensity, bending resistance and torsional property etc.) of himself, prior art is achieved by the following technical solution: existing house roof truss comprises the first roof truss and the second roof truss, between the first roof truss and the second roof truss, entirety is inverted v-shaped, between the first roof truss low side and the second roof truss low side, is connected with crossbeam.Because above-mentioned prior art structure is more complicated, can not meet part client's individual demand, and prior art uses the condition restriction that is subject to operating mode scene, for construction brings inconvenience, be therefore necessary to improve.
Summary of the invention
The purpose of this utility model is the weak point in order to overcome background technology, and a kind of cold bending thin wall arched roof truss for building is provided.
To achieve these goals, the technical solution of the utility model is: cold bending thin wall arched roof truss for building, comprise the first roof truss, and the second roof truss that is connected with the first roof truss upper end and is arranged symmetrically with the first roof truss, it is characterized in that: the both sides, junction of described the first roof truss and the second roof truss are connected with stiffener, described the first roof truss comprises upper chord, lower chord, end web member and multiple middle web member, between adjacent two middle web members, form similar equilateral triangle, angle between middle web member and lower chord is 45～70 °, described end web member is positioned at upper chord with lower chord two ends and is connected upper chord and lower chord, described middle web member is between upper chord and lower chord and connect upper chord and lower chord, angle between described upper chord and horizontal plane is 30～60 °, angle between lower chord and horizontal plane is 15～45 °, angle between upper chord and lower chord is 6～20 °.
Upper chord 5, lower chord 6, end web member 7 and middle web member 8 are cold bending thin wall C-shaped steel component, and the wall thickness of C Steel section member is preferably 0.65～0.75mm.
Between adjacent two Pin roof trusses, carry out fastening (upper chord is connected with upper chord, and lower chord is connected with lower chord) every 600～1200mm with C Steel section member, to prevent that roof truss is unbalance and so that roof building material is installed.
Cold bending thin wall arched roof truss for building described in the utility model adopts cold bending thin wall C-shaped steel component as basic component, and it has the incomparable advantage of other building types in structure aspects:
1.: be conducive to industrialization, industrialization production.The utility model 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. formed, therefore met industrialization sizing and produced, the feature of on-site consolidation.
2.: green building, energy saving building.The environmental disruption of the utility model the utility model and pollution are few, and easily, material is recyclable high with regeneration rate for reconstruction and removal.Therefore, the utility model has reached the requirement of green building, adopts the light material of its supporting technology simultaneously, more meets the requirement of energy saving building.
3.: the utilization rate that improves space.Because the utility model has adopted light roof and wall body structure, and the utility model braced structures (cold bending thin wall C shaped steel) intensity is high, and materials are economized, small, so from heavy and light.Therefore while doing support system with steel work, can build the standard width of a room in an old-style house, depth is larger, the house of the indoor flexible isolation of not establishing post of house type meets the requirement of architectural plane function; The space availability ratio that can improve house simultaneously, is suitable for the transformation of the vertical interlayer of house, local staggered floor.And the cross section of required member is little, the architectural space utilization rate under identical building area increases 5-8%.
4.: the utility model, by the connection of tapping screw between rod member, can be manufactured various shapes, therefore, make design advanced more flexibly, it can complete its building function and art of building feature according to designer's wish.
5.: because the utility model is lightweight, volume is little, and steel work itself has good ductility, the situation analysis that therefore antidetonation of its steel house is destroyed, and this type of structural construction is obviously better than brick mix structure and reinforced concrete frame structure.
6.: reduce foundation cost.Because the utility model deadweight is lighter, therefore its foundation load also reduces accordingly, therefore reduce difficulty of construction and the cost of Foundation Design.
7.: short construction period, the returns of investment of raising fund, job site civilization.Except foundation construction, member is all produced by professional factory normalization, speed of application is fast, construction period shortens half than traditional architecture, each parts transport Assembling to, job site civilization situ wet operation is few, noise dust and building waste are also few, meet the requirement of environmental protection, construction operation is subject to weather and seasonal effect less (winter can at produce in factory steel member), and can make produce in factory and parallel the carrying out of on-the-spot installation, even some standardized dwelling house systems, can order goods at any time, build at any time, shortening production cycle and the occupation of capital time greatly.
8.: comprehensive benefit index is high.The direct cost of the utility model is a little more than about 5% left and right of concrete structure.But its economic benefit, social benefit are high, and in today of program of real estate enterprise keen competition, it is the concentrated reflection of program of real estate enterprise comprehensive strength, for improving enterprise product brand, all larger impacts of the social popularity that improves enterprise.
