The invention provides a kind of prestressing force assembling slab column system supporting with steel, the setting that steel supports can replace the shear wall in original structure, greatly reduces dead load, and the Hysteresis Behavior that steel supports is on the other hand better, the effectively lateral displacement of control structure, the anti-seismic performance of raising structure.
According to the prestressing force assembling slab column system supporting with steel of the present invention, by the prefabricated post with built-in fitting, precast plate and steel, support and form, precast plate is two-way close rib precast plate with ribbing, built-in fitting and the moulding of prefabricated post formed by integrally casting, the prestressing force that prefabricated post produces by presstressed reinforcing steel and frictional force and precast plate link together, and steel supports and is connected with the built-in fitting of prefabricated post by high-strength bolt.
Preferably, built-in fitting is comprised of two single angles, a gusset plate and four crab-bolts with crotch, single angle comprises first side and Second Edge, and gusset plate splices between the first side of two single angles, and crab-bolt is stretched out respectively and is anchored in prefabricated post from the Second Edge of single angle.
Preferably, between single angle and gusset plate, by high-strength bolt, splice, steel supports and is connected with the gusset plate of built-in fitting by high-strength bolt.
On the other hand, the present invention relates to a kind of method of building above-mentioned prestressing force assembling slab column system, comprise the following steps:
(1) in factory, built-in fitting, prefabricated post, precast plate and steel support manufacturing are completed, wherein built-in fitting and prefabricated post are by the crab-bolt formed by integrally casting moulding with crotch;
(2) prefabricated post with built-in fitting and precast plate being transported to job site applies prestressing force and splices;
(3) steel is supported with gusset plate and be connected to form by high-strength bolt the prestressing force assembling slab column system supporting with steel.
The prestressing force assembling slab column system supporting with steel provided by the invention has the following advantages:
1. make processing simple, easy for installation.Plate in structure and post all can prefabrications, are easy to ensure the quality of products, and on-the-spotly only each member need be lifted to splicing, easy for installation, can obviously improve the comprehensive benefit of structure.
2. the steel in the present invention supports and can replace the shear wall in existing structure, greatly reduces dead load, increases economic efficiency to a great extent, cost-saving.
3. the Hysteresis Behavior that steel supports is better, and the effectively lateral displacement of control structure meets the antidetonation demand of structure.
