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). At least one reinforcing steel bar (5) parallel or crossed with the upper chord is in the soleplate; the web member is connected with the reinforcing steel. 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 to set up the interim scaffold of regulation at the construction field (site), and sets template, and configuration reinforcement as required, the concrete cast is carried out at the scene then.What replace the template 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 corresponding scaffold 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 and prestress concrete template etc., and still, 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, and is too high as cost, and weight is too big, and is light inadequately.When for example adopting profiled sheet as the permanent formwork do not removed, though the intensity height, rigidity is big, the cost height, and simultaneously, the easy corrosion of the steel form that exposes has a strong impact on the attractive in appearance of building and uses.When adopting concrete form as the permanent formwork do not removed, as the patent No. is 03227765.2, name is called the utility model patent of " a kind of floor spiced by steel reinforced concrete ", Instructions Page 3 the 13rd in this patent walks to the implementation that has specifically described this utility model in the 22nd row, " this floor spiced by steel reinforced concrete; comprise precast member for reinforcing bar concrete; reinforcing bar; floor is assemblied to form by the polylith precast member for reinforcing bar concrete; both sides have hole under the precast member for reinforcing bar concrete longitudinal rib; reinforcing bar passes the hole of member both sides, connect the polylith precast member for reinforcing bar concrete, after floor spiced, in the groove again concreting fill and lead up."; in this utility model patent scheme; floor is assemblied to form by the polylith precast member for reinforcing bar concrete; and form crisscross layout and form bi-directional configuration by now wearing the existing reinforcing bar of reinforcing bar and precast member for reinforcing bar concrete; do not need on-the-spot formwork; now wear the original reinforcing bar of reinforcing bar and precast member for reinforcing bar concrete and form crisscross layout, can bear bidirectional load, but, itself be check configuration, need now wear reinforcing bar and can bear bidirectional load, and, its member longitudinal rib structure has caused horizontal partition, be not easy to pipeline and wear, the shear resistance at the superimposed interface between Cast-in-place concrete and the template is low, the reinforcing bar that superstructure or roof construction are used, material consumptions such as concrete are big, the cost height, globality is poor.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, can participate in the common power transmission of load-carrying construction, and have intensity height, strong, the characteristics such as cost is low, good integrity of rigidity shear resistance big, superimposed interface.
Solution of the present invention is on the basis of existing technology, comprise base plate, it is characterized in that also including upper chord, web member, upper chord and base plate connect into integral body by web member, constitute the space load-carrying member of bar plate girder, the reinforcing bar of at least one or quadrature parallel with upper chord is arranged in the base plate, and web member and reinforcing bar connect into integral body.Like this, owing to also include upper chord, web member, upper chord and base plate connect into integral body by web member, constitute the space load-carrying member of bar plate girder, the reinforcing bar of at least one or quadrature parallel with upper chord is arranged in the base plate, web member and reinforcing bar connect into integral body, when this force-bearing type superposed component is applied to In-situ cast concrete board, but the common power transmission of participation structure, and the intensity height of superposed member, rigidity is big; And, can improve the mutual wedge action between Cast-in-place concrete and the truss greatly, improve the shear resistance at the superimposed interface between Cast-in-place concrete and the superposed member, improve the overall performance of superstructure, simultaneously, can give full play to the mechanical property of truss member, reduce the consumption of the reinforcing bar of In-situ cast concrete board, the thickness of attenuate In-situ cast concrete board reduces cost, in addition, superposed member can be realized producing in enormous quantities in factory, help reducing production costs and construction cost, be applicable to the hollowcore slab of various cast-in-situ reinforced concretes or prestressed reinforced concrete, superstructure, roof system, sole plate, body of wall and bridge use, and are specially adapted to arch without beam and use.
