Described truss bars net and two lower chords between sustained height place also establish the Reinforcement parallel with lower chord.
Described truss is parallel chord truss, comprises at least two upper chords that be arranged in parallel, at least two lower chords that be arranged in parallel, two web members, at least one bending reinforcing steel bar; Between described upper chord, be connected to same plane by bending reinforcing steel bar; Upper and lower chord member is connected by web member.
Described bending reinforcing steel bar is waveform or bow font.
Described truss is triangular truss or parallel chord truss, comprises a upper chord, at least two lower chords that be arranged in parallel, two web members; Described upper chord is horizontally disposed with, and two web member upper ends are connected in upper chord lower surface, and lower chord is connected to web member bottom.
Described upper chord is reinforcing bar, steel plate, shaped steel or steel pipe.
Handling reinforcement described in the utility model is plain bars, and effect is to connect stirrup, and for it provides fulcrum, its quantity can change flexibly;
Stirrup described in the utility model is plain bars, the Reinforcement that it connects lower chord, handling reinforcement and may set up.
The beneficial effects of the utility model:
1. when beam is constructed, without temporary supporting, can reduce corresponding artificial and Master Cost, be conducive to improve speed of application, when what is more important is multilayer superstructure, precondition has been created in construction.
2. for floor provides larger shelving length, during for construction, remove restriction without the application of temporary supporting floor, will bring the decline of lifting greatly, labour demand and correlative charges of floor construction speed.Development for assembled architecture will be significant.
3. because truss can effectively connect preformed layer and overlapping layers, make the globality of superposed beam obtain strong assurance.
4. superposed beam scene, except the reinforcing bar at bearing place, without layout and the colligation of other extra reinforcing bars, and does not need template, and site work amount is very little, and site operation is simple and quick, and artificial demand is very little.
5. steel bar girder can suitability for industrialized production, precast plate suitability for industrialized production, and upper and lower protective layer thickness is secure, and site operation is simple, and the quality of superposed beam can effectively be guaranteed.
Situ wet workload reduce, without support and template, consumptive material is few, economizes on resources and expense, and is conducive to safety construction and protection of the environment; The batch production of preformed layer, artificial, support and formwork cost reduces and speed of application promotes the comprehensive benefit of bringing, makes this superposed beam have stronger competitiveness.
