The upper chord connected to the whole with the soleplate by the web member to form the room load-carrying component of the bar-plate girder (4). So it is used for the hollow board, the floor, the roof, the base soleplate, the wall and the bridge of pouring reinforced concrete or the prestressed reinforced concrete, especially for the hollow floor with no girder.
Description
(1) technical field
The present invention relates to a kind of force-bearing type superposed component for concrete building lid.
(2) background technology
At present, the main Cast-in-place concrete monobloc cast that adopts such as the superstructure of multi-rise building, roof system, general job practices is process regulation at the construction field (site) interim framed, and configuration reinforcement as required, the concrete cast is carried out at the scene then.What replace the framed construction used in this scene is in advance in the prefabricated template of plant-manufactured what is called, then this prefabricated template is moved into the scene, be installed on the building and construct, because its operation advanced person, can the reduction of erection time, so be widely adopted in recent years.The template that this class is made in advance has profiled sheet, concrete form etc., but, also there are some problems in the prefabricated template of this class in In-situ cast concrete board construction application processes such as Cast-in-place Concrete Building Floor, roof system, intensity as template is not high, rigidity is little, the shear resistance at the superimposed interface between Cast-in-place concrete and the template is low, material consumptions such as the reinforcing bar that superstructure or roof construction are used, concrete are big, cost height, globality difference etc.Therefore, develop a kind of novel force-bearing type superposed component for concrete building lid for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of force-bearing type superposed component for concrete building lid, when being applied to In-situ cast concrete board, have intensity height, strong, the characteristics such as cost is low, good integrity of rigidity shear resistance big, superimposed interface.
