Background technology
When structure was made by precast concrete plank, common connected mode was welding.At the connecting line place of each concrete slab, steel part is molded in each concrete slab, is arranged so that and can welds, and is rigidly connected thereby form between concrete slab.
These steel parts are not followed a standard, but make in each is used.Usually steel part is in the local production of concrete slab manufacturer, and this manufacturer is usually as the steel reinforcement that is used for concrete slab.The scheme that its result normally prepares temporarily, expensive and inappropriate steel part.Modal equipment is smooth, huge steel plate, and some tubular steel reinforcements are welded to its rear side, to produce tearing toughness.
Select the physical dimension of steel part, so that produce enough mechanical strengths between the concrete slab in this structure, to meet the necessary cross sectional area of fillet welding.Steel part also should be designed to bear the distortion that stress that hot weld produces occurs, and if the steel part temperature surpasses the relevant rank of concrete type, this concrete also will damage.These fringe conditionss often make to be selected the steel part thickness minimum value required far above reality, and often this thickness is not subjected to the control of the analytical calculation value of design stage.
Steel part should have and use relevant minimum tearing toughness, and it can determine with analyzing.Calculated value still carries out actual extension test so that it is confirmed once in a while without the tear-proof characteristic that is usually used in designing steel part.Usually, crooked steel reinforcement is soldered to the rear side of steel part, to increase tearing toughness, still, the most normally is directly to carry out by using available steel reinforcement.
When structure was made by precast concrete plank, the common mode that is used to adhere to door and other light-weight parts was to use bolt or other screwed part.
Light-weight parts is not defined as and loads very big power to its braced structures [concrete slab].The size of these power may be different in each is used, and under every kind of situation, should more clearly limit.
