Abstract
The invention relates to a barrier-free decoration structure of high and low incorporated buildings and a construction method thereof, post-pouring joints are arranged at a horizontal connecting part for the high and the lower buildings, which is close to the ends of the high and the low buildings, and support beams are arranged in the positions for setting the post-pouring joints on the bottom surface of the horizontal connecting part, thereby solving the differential settlement problem of the high and the low buildings, simultaneously solving the problem of enabling the low-rise building to be used as early as possible after completing the structure, having the advantages of simple construction measures, flexibility, effects of accelerating the construction progress and realizing economic benefits as early as possible and the like and being capable of being widely applied in construction of high and low incorporated structures.
Description
Technical field
The present invention relates to a kind of disjunctor building and job practices thereof.
Background technology
Continuous development along with the continuous increase of City Building scale and anti-seismic technology, increasing height building is linked to be an integral body, form in picturesque disorder construction aesthetic perception, also can bring because the potential safety hazards such as relative settlement that difference in height causes to building construction simultaneously, if in work progress, can not well solve these hidden danger, very likely cause structural cracks even destruction.In order to address the above problem, present common way is to connect span centre and stay last-cost joint about 1m arranging, and treats that the height building settlement of both sides builds the last-cost joint concrete after stable.There is following problem in this technology: low-rise building tends to complete than highrise building is early, but before the shutoff last-cost joint, need support with beam and the plate of scaffold to the last-cost joint both sides, finish until high-building construction, just can carry out the last-cost joint construction behind the settlement stability, the use as early as possible that this will have influence on low-rise building tends to cause bigger economic loss.And settlement stability and foundation soil have relation, is difficult to accurately control the time of shutoff last-cost joint.
How to find a kind ofly can solve the height relative settlement, can not influence the use as early as possible of bottom building again, a difficult problem that has just become construction technical staff to face.
Summary of the invention
The purpose of this invention is to provide a kind of height disjunctor and build accessible fitting structure and job practices thereof, solve height disjunctor building owing to settlement difference, low-rise building is out of use technical problem before highrise building does not build up.
For achieving the above object, the present invention adopts following technical scheme:
A kind of height disjunctor is built accessible fitting structure, low building connects as one by being connected horizontal member with high building, described connection horizontal member is reinforced concrete member, the one end is supported on the low major structure of construction primary structure member, the other end is supported on the high building agent structure primary structure member, the bottom supporting of described connection horizontal member has brace summer, at least be installed with two last-cost joints on the described connection horizontal member, described last-cost joint is positioned at the brace summer length range, its both sides are provided with wire lath, the steel bar stress of described connection horizontal member is elongated at the last-cost joint place, and described brace summer one end is fixedlyed connected with low building primary structure member with the high building primary structure member.
Described high building agent structure primary structure member and low major structure of construction primary structure member are beam, post or wall.
Described connection horizontal member is beam or plate.
Described brace summer is cross binding beam, longitudinal bracing beam or both combinations, and the longitudinal bracing beam rides on the cross binding beam or is supported on the adjacent structural beams of striding.
Described brace summer is steel I-beam, the H section steel beam, and steel channel beam or rectangular steel pipe beam, above-mentioned brace summer is welding or rolling.
Described cross binding beam is fixedlyed connected with low major structure of construction primary structure member with high building agent structure primary structure member by built-in fitting, or directly is embedded in high building agent structure primary structure member and the low major structure of construction primary structure member.
The described cross binding beam that connects by built-in fitting be connected the horizontal member contact surface on be welded with peg, the position of burying underground of the cross binding beam of directly burying underground is opened and is worn the muscle hole, and is welded with peg at its external surface.
Described built-in fitting is made up of pre-embedded steel slab and pre-buried anchoring piece, and described pre-embedded steel slab is one or two, and described pre-buried anchoring piece is reinforcing bar or angle steel, is arranged between two pre-embedded steel slabs, and is welded to connect with pre-embedded steel slab.
The width of described last-cost joint is 10～1000mm.
Described height disjunctor is built the job practices of accessible fitting structure, and step is as follows:
After finishing, described step 8 removes the brace summer of horizontal connector bottom surface.
Compared with prior art the present invention has following characteristics and beneficial effect:
At first, can allow the free settling of height disjunctor building in the construction stage, discharge stress, can later stage operations such as finishing not produced obstacle again, make to enter operation stage in advance, effectively improve the utilization of building, thereby effectively increase economic efficiency.
Because structure of the present invention is owing to be provided with twice last-cost joint at least, and the steel bar stress of deformation joint position is elongated, when differential settlement takes place in the height building, the horizontal connector distortion that rotates, reinforcing bar in it can be out of shape with horizontal connector, therefore, need not to adopt sleeve or is welded to connect reinforcing bar, save operation, increased the globality of structure.
The differential settlement of handling between the height building of the present invention by taking simple structural measure, has been realized the just accessible construction of building, and especially low building can be utilized in advance, has accelerated construction speed, has saved construction cost.
The present invention can be widely used in two highly different constructions that building links into an integrated entity.
