First, the economic and technological advantages of reinforced concrete truss floor boards
(1) Fast construction
Reinforced concrete truss floor slabs are directly supported on steel beams or concrete beams. It is not only the reinforced concrete of the concrete floor slab, but also the construction scaffolding is the template of the concrete floor slab, which saves the time for erecting the scaffolding and supporting the formwork.
The reinforced concrete truss floor bearing plate has achieved the steel reinforced material blanking, positioning forming and lengthening in the factory, less steel scrap, and is conducive to environmental protection. The construction site of the floor slab only needs to arrange the horizontal distribution ribs and connecting ribs, and the steel bar binding workload can be reduced by 60-70. %, increase the overall construction speed.
Reinforced concrete truss floor slabs are directly supported on the floor beams. The reasonable force pattern of the trusses provides a spacious and safe working platform for multi-work operations. Pouring concrete and other types of work can be multi-layered and three-dimensional construction, and floors can be simultaneously poured. The advantages of commodity concrete can be brought into full play, and the construction period can be greatly shortened, especially for large-scale high-rise and high-rise buildings with obvious construction period advantages.
(2) good stress performance
The self-respect of the concrete floor is completely borne by the steel bars and does not generate tensile stress in the concrete. The tensile stress of the concrete in the negative bending moment zone and the positive bending moment zone of the service period is significantly reduced, the crack width is reduced, and the presence of galvanized steel sheet prevents the exposed cracks below the floor slab. Improves floor performance and durability.
After using reinforced truss floor boards, the floor board can be designed as a two-way board according to needs, which is equivalent to the traditional cast-in-situ reinforced concrete two-way reinforcement floor slabs. The press-type steel sheet combination floor slab is difficult to realize two-way slabs, and the use of two-way slabs not only reduces floor slabs. The thickness of the structural layer, reducing the weight of the structure, increasing the span and opening, and more economical and reasonable. The steel bars are completely covered with concrete and have a reliable fire resistance, equivalent to traditional cast-in-situ floor slabs. The test results indicate that when the floor thickness is 100mm thick (corresponding to a truss height of 70mm), the fireproof time limit is 1.68 hours, and the galvanized steel sheet does not require fire protection.
Reinforced truss floor boards are made of galvanized steel sheet, which has anti-corrosion function. However, the role of galvanized steel sheet is not considered in the use stage and no anti-corrosion treatment is required. Compared to the profiled steel plate combination floor, the reinforced truss floor plate has superior anti-corrosion performance.
The overall rigidity of the floor slab is small, the vibration is small, the sound insulation performance is good, the floor surface is flat and easy for building decoration. The deflection of the reinforced concrete truss floor slab is less than the deflection of the traditional profiled steel floor slab.
(3) Good economy
The lower surface of the reinforced concrete truss floor is smooth and beautiful, and there is no need for pressure plate ribs and corrugations. The utilization rate of the galvanized steel plate is 96%, and the thickness is only 0.5mm. Compared with conventional profiled steel plates with a thickness of 0.8-1.2mm, the use of profiled steel plates has been changed, only as a template for the construction of floor slabs, reducing the thickness of steel plates and the thickness of galvanized layers. Reduced costs and better economics.
The total thickness of concrete floor slabs of reinforced concrete truss floor slabs can be reduced by 30 mm to 50 mm compared to the use of ordinary profiled steel slabs. Under the same headroom requirement, the building height can be reduced by 30 mm to 50 mm. For buildings with high-rise buildings and seismic fortification zones, there are obvious advantages in saving investment.
The galvanized steel sheet is only 0.5mm thick, the power consumption of the field peg penetration welding is greatly reduced, the demand for electricity at the site is reduced, and energy is saved. After the floor slab concrete is completed and reaches the design strength, the galvanized steel sheet can be dismantled for recycling, which not only satisfies the needs of the floor of the structural floor, but also contributes to environmental protection.
