Description

The sleeper formula is assembled building to withstand earthquake and engineering method entirely

Technical field

The present invention relates to a kind of full assembling building to withstand earthquake and job practices thereof.

Background technology

Architectural industrialization is the inexorable trend of construction industry development, factory's formula mechanization production of building unit, standardized construction, intensive management, scientific management, reach the high unity of fund and technology, thereby creating the livable building of high-efficient energy-saving environment friendly, is the inevitable requirement of social progress.

Assembled architecture because the construction period is short, quality is higher, environmental protection and energy saving, construction safe, need at western developed country, be widely used by advantages such as the labour are few.In China, because reducing day by day with security incident, the labour who is engaged in builing industry takes place frequently, and assembled architecture has been included development plan in, and many enterprises and R&D institution start experimental exploitation already.In existing assembled architecture, the processing of assembly node does not all reach shockproof requirements and installation requirement usually, be difficult to large scale application aspect highrise building, particularly can't solve antidetonation and the installation question of prefabricated post and precast beam node, prefabricated post and precast wall body node.Prefabricated panel only manufactured and installs usually by the assembling high-rise building, the crucial supporting member such as post, beam still needs to pour into a mould at the construction field (site), cause the construction part of building to be prefabricated in the factory, another part is wet trade at the scene, can only realize the partial assembled industrialization, can't solve and guarantee to realize simultaneously post, beam and wallboard prefabricated, the full assembling manufacture entirely of building under the shockproof requirements prerequisite.

Summary of the invention

The purpose of this invention is to provide a kind of sleeper formula and entirely assemble building to withstand earthquake and job practices, solve in traditional assembled architecture, assembly node does not reach the technical problem of shockproof requirements or installation requirement, solving simultaneously traditional assembled architecture can't guarantee under the shockproof requirements prerequisite, and post, beam and the wallboard of realizing simultaneously building be the technical problem of prefabricated, full assembling manufacture entirely.

For achieving the above object, the present invention adopts following technical scheme:

A kind of reserved sleeper duct prefabricated post, its cylinder is to be formed by reinforced concrete prefabricated, the core of described cylinder along the column length direction have at least one elongated be used to wearing reinforcing bar, fluid concrete, construct the reserved sleeper duct of sleeper.

Described cylinder is that cross section is that criss-cross cross column, cross section are that T-shaped t head post, cross section are that L shaped corner post or cross section piled up neatly the door side column of shape for door.

A kind of sleeper formula is assembled building to withstand earthquake entirely, comprise basis, prefabricated post, precast beam, prefabricated panel, precast floor slab and precast stair, described prefabricated post is reserved sleeper duct prefabricated post, reserved sleeper is installed with a branch of sleeper reinforcing bar in duct, and being solidified as sleeper in cylinder with the pea gravel concreten of cast, the top of reserved sleeper duct prefabricated post is connected with beam column edge sealing steel plate;

The position of the inherent joint pin in described basis is embedded with pre-embedded steel slab and basic reserving rib bundle in basis, the bundle number that described basic reserving rib bundle protrudes upward is identical with reserved sleeper duct prefabricated post number, its extension elongation is not less than 600mm, described basic reserving rib bundle stretch out termination from reserved sleeper opening of the channel at the bottom of the post of reserved sleeper duct prefabricated post pierce into duct in the sleeper bar splicing, lap-joint is by centring ring and steel bar end anchoring.

Expose at the two ends of described precast beam built-in fitting, described built-in fitting passes the part that the sleeper reinforcing bar stretches out capital, at bean column node place anchoring together, the Si Ge corner, two ends of beam is embedded with beam bound edge shaped steel, described beam bound edge shaped steel and beam column edge sealing steel plate weld at the bean column node place, and are consolidated into one with concrete.
