Description

A kind of bearing type base plate member
(1) technical field
The present invention relates to a kind of bearing type base plate member.
(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 base plate, and configuration reinforcement as required, the concrete cast is carried out at the scene then.The base plate construction that replaces using in this scene be in advance at the prefabricated base plate of plant-manufactured what is called, then this prefabricated base plate 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 base plate that this class is made in advance has profiled sheet, concrete base plate and prestress concrete base plate etc., and still, also there are some problems in the prefabricated base plate 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 base plate do not removed, though the intensity height, rigidity is big, the cost height, and simultaneously, the easy corrosion of the steel sole plate that exposes has a strong impact on the attractive in appearance of building and uses.When adopting the concrete base plate as the permanent base plate 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, the Cast-in-place concrete in this floor and the shear resistance at the superimposed interface between the base plate are low, material consumptions such as the reinforcing bar that superstructure or roof construction are used, concrete are big, the cost height, and globality is poor.Therefore, develop a kind of novel bearing type base plate member for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of bearing type base plate member, 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.
Solution of the present invention is on the basis of existing technology, comprise base plate, it is characterized in that also including the truss of parallel alternate laying, truss is arranged on the base plate, and the formation that links to each other is whole, and truss is provided with upper chord, lower chord, web member, and web member links to each other with lower chord with upper chord, the lower chord of truss is cemented in the base plate, forms whole long slab truss with base plate.Like this, the lower chord of truss is cemented in the base plate, form whole long slab truss with base plate, in transportation and install in the application process, not fragile, coming off has guaranteed the quality of product, simultaneously, base plate member can be realized producing in enormous quantities in factory, help reducing production costs and construction cost, be applicable to that hollowcore slab, superstructure, roof system, sole plate, body of wall and the bridge of various cast-in-situ reinforced concretes or prestressed reinforced concrete uses, be specially adapted to arch without beam and use.
