Description

The cast-in-place Integral Steel frame wall filled with masonry system of the spacing connection of steel disc and construction method
Technical field
The present invention relates to building engineering field, particularly a kind of filling wall construction system and construction method thereof.
Background technology
Frame wall filled with masonry some small-sized hollow building blocks of many employings or porous brick are built by laying bricks or stones at present, be connected by a number of lacing wire with agent structure, but this structure exists certain defect.
For structure tension performance, due to the problem of masonry quality, filling wall overall performance is poor, under geological process, fills wall and the sliding rupture of masonry mortar layer easily occurs.Meanwhile, easily there is shrinkage phenomenon during air-drying in masonry mortar, and causes filled wall to occur sedimentation to depart from Vierendeel girder, thus produces crack.
For from construction, building block or building by laying bricks or stones of brick body are wasted time and energy, and add cost of labor, reduce efficiency of construction.
For the energy-saving heat preserving angle of body of wall, existing building block and brick body material can not reach body of wall energy-saving heat preserving requirement mostly, need to do external thermal insulation at surface of wall and process, and external thermal insulation usually uses the inflammable sheet material such as styrofoam, extruded sheet, there is disaster hidden-trouble in building, adds potential safety hazard.
In addition; the Slope protection filling wall in steel-frame structure is mainly under geological process; filling wall and steel frame can not cooperative transformation; mostly because steel frame and filling wall are to be rigidly connected; relative displacement and corner is not had between steel frame and filling wall; therefore, fill wall and be the most directly destroyed in earthquake, lose the Protection significance of body of wall itself.
Summary of the invention
It is an object of the invention to provide cast-in-place Integral Steel frame wall filled with masonry system and the construction method of the spacing connection of a kind of steel disc, solve existing steel frame fill that wall overall performance is poor, insulation and the bad technical problem of anti seismic efficiency;Solve steel frame and fill wall problem of deformation under geological process;And solve existing steel frame filling wall construction problem complicated, inefficient.

The setting of steel disc stopping means of the present invention and reinforced mesh is effectively guaranteed cast-in-place filling wall and the disengaging of rectangular frame, and ensure under geological process or wind action, rectangular frame and cast-in-place filling wall can really realize relative level sliding, reach the purpose that both flexibly connect, and due to the spacing stop outer to wall plane of steel disc stopping means, it is to avoid cast-in-place filling wall throws away destruction under geological process.
The cast-in-place filled wall of the present invention uses up-narrow and down-wide trapezium structure, and matched steel disc stopping means is then wide at the top and narrow at the bottom, up big and down small consistent with rectangular frame displacement under geological process, avoids the destruction of cast-in-place filled wall to greatest extent.
The cast-in-place filled wall of the present invention uses one-piece casting, and the wall integrity after pouring can be good, and body of wall itself can regard a rigid body as, does not haves crack.Concrete material used has the feature of light weight, and under geological process, the geological process suffered by body of wall is little, reduces the possibility that body of wall is destroyed under geological process to greatest extent.
For overall performance, there is compared with building block and brick masonry superior overall performance, it is to avoid during use, crack occurs in body of wall self, it is to avoid body of wall generation local failure under geological process.
For construction, the form of construction work of cast-in-place concrete, save the input of the time of building by laying bricks or stones and manpower, improve efficiency of construction, reduce construction cost.
For heat-insulating property, outer filling wall is that self-heat conserving fills wall, it is achieved structural thermal insulation integration, has good thermal and insulating performance, it is to avoid hollowing that external application insulation material occurs, ftracture, the defect such as come off, and has saved the construction cost of external thermal insulation.
To sum up, the present invention uses the mode flexibly connected, it is allowed to occur relative displacement and corner between rectangular frame and filled wall, is that a kind of cast-in-place monoblock type fills wall, its efficiency of construction is high, overall performance is good, reduce labor intensity, and good as first anti-vibration defense lines anti-seismic performance.
The composite can be widely applied to steel frame and fill wall construction.
