A kind of little, easy for installation and prestressing force assembling slab column system that anti-seismic performance is good of conducting oneself with dignity is needed in prior art.
Summary of the invention
The invention provides a kind of prestressing force assembling slab column system with bracing members, the setting of bracing members can replace the shear wall in original structure, greatly reduces dead load, and the Hysteresis Behavior of bracing members is better on the other hand, can the lateral displacement of effective control structure, improve the anti-seismic performance of structure.
According to the prestressing force assembling slab column system of band bracing members of the present invention, form by with the prefabricated post of built-in fitting, precast plate and bracing members, precast plate is two-way close rib precast plate with ribbing, built-in fitting and prefabricated post formed by integrally casting shaping, the prestressing force that prefabricated post is produced by presstressed reinforcing steel and frictional force and precast plate link together, and bracing members is connected with the built-in fitting of prefabricated post by high-strength bolt.
Preferably, built-in fitting is made up of the crab-bolt of two single angles, one piece of gusset plate and four band crotches, single angle comprises the first limit and Second Edge, and gusset plate splicing is between the first limit 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, spliced between single angle and gusset plate by high-strength bolt, bracing members 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) built-in fitting, prefabricated post, precast plate and bracing members are completed in factory, wherein built-in fitting and prefabricated post are by being with the crab-bolt formed by integrally casting of crotch shaping;
(2) splice being transported to job site Shi Hanzhang with the prefabricated post of built-in fitting and precast plate;
(3) bracing members is connected to form the prestressing force assembling slab column system with bracing members by high-strength bolt with gusset plate.
The prestressing force assembling slab column system of band bracing members provided by the invention has the following advantages:
1. processing is made 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 component need be carried out lifting and splice, easy for installation, can significantly improve the comprehensive benefit of structure.
2. the bracing members in the present invention 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 of bracing members is better, can the lateral displacement of effective control structure, meets the antidetonation demand of structure.
