Description

A kind of force-bearing type template component

(1) technical field

The present invention relates to a kind of force-bearing type template component.

(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 this member longitudinal rib structure has caused horizontal partition, is not easy to pipeline and wears, 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, and globality is poor.Therefore, develop a kind of novel force-bearing type template component for being badly in need of.
