Description
Technical field
The utility model relates to a kind of Portal Frames of Light-weight Steel Structures, and specifically, what relate to is a kind of angle brace cold working bracing means.
Background technology
Current increasing solar photovoltaic power plant is built on original steel concrete and steel structural plant roof, due to it, can Roof Resources to be installed limited, when installable roofing often designed originally in order to control cost, do not consider that roofing can set up load, design surplus capacity is few, therefore at the local structure increasing after load, can not meet intensity and rigidity requirement completely through retrying; In the case, build again power station, meet Structural Design Requirement again, just need to carry out local stiffening and meet Structural Design Requirement, want can be by the confirmation of former design school or third-party design institute simultaneously.
Existing steel-structure factory building adopts Portal Frames of Light-weight Steel Structures pattern mostly, and its design feature is; Roofing adopts lightweight structures (roof panel), beam cross-section reduces relatively, basis also reduces relatively, the angle brace of the lateral rigidity nationality purlin of rigid frame design guarantees, save longitudinal rigid member, can reduce like this flange width, make structure stress more reasonable, cost has good cost performance.But due to gantry beam planar with plane outward all by bending component computed strength and stable, design purlin arranges all by 1.5 meters of settings, angle brace arranges all by 3 meters of layouts, the out-of-plane calculated length of gantry beam is general presses 3 meters of designing and calculating; But theoretically, the tightness degree that angle brace arranges, has strengthened better the globality between steelframe crossbeam and purlin, and can improve purlin rigidity planar.
The load that the construction reality of photovoltaic increases on roofing is 15KG/m2 left and right, comprises solar module, aluminium alloys mounting bracket, electric wire cable bridge etc.According to design of building structures load code, depending on area, the roof live load of steel work is generally 50kg/m2 left and right, for example: Physicians in Shaoxing Area: snow load is 45kg/m2, after using professional structure software for calculation to retry, in the time that gantry beam Out-of-plane Effective Length is 3 meters, gantry beam plane there will be part rigidity not meet the demands outward, but in the time that Out-of-plane Effective Length setting is adjusted into 1.5 meters, because plane has been strengthened lateral support rigidity outward, therefore rigid frame strength and stiffness all can meet the designing requirement after loading.The reinforcing that absolutely proves angle brace makes overall rigid frame system be strengthened and improve.
Meet theoretically after designing requirement, just need in Practical Project, used and realize.Therefore the reinforcing of setting up of the rigid frame angle brace to original roofing has proposed new problem.What employing is set due to traditional angle brace is full welding method, installation technology falls behind, and junction node is coarse, and factory building has all dropped into overall production operation at present, for fear of the fire safety requirement of impact production and factory building, the construction that roofing is reinforced had not both adopted member Site Welding scheme completely.Current object of construction production structural system not only needs to meet outside bearing capacity and stiffness requires, also should focus on the renewal of structure node details construction technique, change the defective work that engineering node processing is relatively coarse, make object of construction production rise to a more level for Gao Gengxin.
