Description

A kind of high-low connected house relative settlement reply structure

Technical field

This utility model is related to a kind of structure of reply high-low connected house relative settlement.

Background technology

Constantly increase the requirement with anti-seismic technology with City Building scale, increasing height building is linked to be One entirety, the larger building of difference in height has differences the problem of sedimentation, is likely to result in structural cracks and even destroys, there is peace Full hidden danger.In order to solve the above problems, at present generally adopt post-cast strip, span centre stay 1m about post-cast strip, treat the height of both sides Concrete on the stable after-pouring of low building settlement, this technology is there is problems in that before closure post-cast strip, need to use foot Hand cradle is supported beam and the plate of post-cast strip both sides, and this will have influence on the low-level portion that can start a business in early days, and settles Stable and foundation soil has relation it is difficult to accurate control the time blocking post-cast strip.

How to find one kind and can solve height relative settlement, can not affect to fit up again, the technology of normal business is to solve The difficult problem that high-low connected building relative settlement is faced.The immediate prior art solving problems is patent Cn201110125443, discloses a kind of high-low connected building barrier-free decoration structure and its construction method, this patent after pour Bottom surface with position, existing contignation is additionally arranged support beam, and support beam is located on the downside of contignation.And this kind of structure is passed through Find after scene is actually used, this structural beam slab lower space strongly reduces, and is highly detrimental to later stage decoration construction, pours afterwards simultaneously At band position, support beam only plays supporting role, and node power transmission stressing conditions do not occur big improvement, at post-cast strip still It is subject to the weak link of load.

Utility model content

The purpose of this utility model is to provide a kind of high-low connected house relative settlement reply structure, solve existing no to hinder Hinder beam slab lower space present in fitting structure to strongly reduce, at the position of post-cast strip power transmission stressing conditions do not occur big Improve the technical problem of the weak link being still bearing load.

For achieving the above object, this utility model adopts the following technical scheme that

A kind of high-low connected house relative settlement reply structure, including low building, high building and level connection joint component, level The two ends of connecting elements are connected with low building primary structure member and high building primary structure member respectively, and described level connection joint component includes steel Reinforced concrete main body and support steel beam, described support steel beam be embedded in adjacent reinforced concrete bodies inside and corresponding at least provided with Two, described adjacent reinforced concrete bodies are located in the range of support steel beam and are installed with least twice construction hinge, described reinforced concrete The steel bar stress of native main body is elongated at construction hinge.

Described low building primary structure member and high building primary structure member are beam, post or wall.

Described level connection joint component is beam.

Described support steel beam is the combination beam that single cross-brace beam or cross-brace beam are connected with longitudinal support beam, institute State longitudinal support beam two ends be connected to adjacent across cross-brace beam on.

Described support steel beam is steel I-beam, H type girder steel, steel channel beam or rectangular steel pipe beam, production method be welding or Rolling.

In described whole embedment adjacent reinforced concrete bodies of cross-brace beam, or whole embedment reinforced concrete of cross-brace beam While in native main body, its one end extends in embedment low building primary structure member and high building primary structure member.

Described cross-brace beam is imbedded with low building primary structure member and high building primary structure member and is all provided with the contact surface at position There is peg, this embedment position also has concrete trickling hole or first and wears muscle hole.

Described longitudinal support beam is fixedly connected with cross-brace beam by connecting plate, and connected mode is welding or bolts, institute State and have second on connecting plate and wear muscle hole.

The width of described construction hinge is 10～1500mm.

Compared with prior art this utility model has the characteristics that and beneficial effect:

First, support steel beam being imbedded in advance level connection joint component is in beam, before beam slab thickness and applying support steel beam Identical, lower space will not be compressed, later stage finishing is convenient without consideration construction.

Secondly, in underground particularly basement construction, at post-cast strip, only has the steel bar stress of level connection joint component Bear the horizontal pressure force from both sides, horizontal pressure force cannot effectively transmit herein, support steel beam embedment of the present utility model In level connection joint component, particularly can also imbed in post further, preferably transmit horizontal pressure force.

Further, it is still the more weak link of bearing load at post-cast strip, this utility model support steel beam imbeds level In connecting elements, ultimate bearing capacity of joints is significantly improved.

This utility model passes through improvements over the prior art, beneficial to height building free settling, reduces settlement stress, keeps away Exempt from security risk, be conducive to low area building to fit up in advance and normal operation, advantageously reduce crack.This utility model is conducive to Lifting lower space, without consideration, it is convenient to construct, and can effectively transmit horizontal pressure force, beam-ends shearing resistance is held simultaneously for later stage finishing Load power is significantly improved, and is advantageously implemented the performance of the strong shear capacity and weak bending capacity of agent structure, and then improves shock resistance.
