Description
Technical Field
The utility model belongs to the technical field of the building engineering assembled, concretely relates to exempt from to support steel bar truss built-up plate of removable die block.
Background
With the year-by-year reduction of the young labor force engaged in the construction of the building engineering and the transformation and upgrading of the building industry, the popularization strength of the assembly type structure is gradually increased by the nation, and the popularization strength of the assembly type structure is increased in all places recently. Regardless of the fabricated steel structure or the fabricated concrete structure, the floor slab adopts the fabricated floor slab, and the fabricated floor slab adopted at present generally adopts the prefabricated composite floor slab of the steel bar truss and the steel bar truss floor bearing plate. The prefabricated laminated floor slab with the steel bar trusses is characterized in that prefabricated slabs with the thickness of 50-60 mm are prefabricated firstly, the steel bar trusses are embedded in the prefabricated slabs, and the floor slab has four remarkable defects: (1) The floor at the joint basically generates shrinkage cracks because the effective thickness of the floor slab at the joint is only the thickness of the post-pouring laminated layer and is much smaller than that of the floor slab at the non-joint, and the floor slab cracks at the joint due to stress concentration when the concrete shrinks; (2) The prefabricated laminated slab is heavy and needs to be hoisted in place by a tower crane, so that the construction period is influenced; (3) it is difficult to make a bi-directional plate; (4) When the plate bottom is applied to civil residential buildings, the joints at the plate bottom are not attractive, and the pipeline is not convenient to embed. The steel bar truss floor bearing plate is formed by spot welding a galvanized steel plate with the thickness of about 0.5mm below the steel bar truss, and the galvanized bottom plate is only used as a template and does not participate in structural stress. The steel bar truss floor support plate also has three disadvantages: (1) The galvanized steel plate as the template is easy to rust, the appearance of a building is influenced, and the bottom plate is too smooth and is not easy to plaster; (2) The galvanized steel plate as the template does not participate in structural stress and can not be disassembled, so that waste is caused, namely at least 4 kilograms of steel bar steel is wasted per square meter, 400 tons of steel is wasted in 10 ten thousand square meters, and the general policy of energy conservation and environmental protection in China is not met; and (3) the floor slab is inconvenient to cut.
At present, the steel bar truss floor bearing plate with the detachable bottom die is tried on the market, but the use is not simple and convenient, especially, the number of bolts below the bottom die is too large, the form removal is time-consuming, and too many bolts are left at the bottom of a floor slab after the form removal, a nut buried in concrete cannot be removed, although the nut does not protrude out of the bottom surface of the floor slab, the mark is obvious, the appearance is influenced, for example, a glued wood template is taken as an example, the width range of 3 meters in span of 0.915 meters is required, at least three steel bar trusses are required, two lower chord steel bars of each steel bar truss need bolt lifting points, the distance is within 600mm, and two ends are required to be encrypted, so that the range of 3 meters multiplied by 0.92 meters needs 42 bolt lifting points. Because the hoisting point bolt is flush with the bottom of the plate, the repair by cement mortar cannot be carried out, the appearance is influenced, the workload of removing the die is large, and at least 42 nuts need to be removed when the bottom die in the range needs to be removed, thereby wasting time and labor.
