The self-adapting split column is characterized by comprising a reinforced concrete bar unit and an entire cross-section column with a separation material, wherein the reinforced concrete bar unit consists of 2 or 4 bar subunits; the separation material is arranged between the bar subunits, and is perpendicularly arranged at set parting positions along the reinforced concrete bar unit to ensure that the concrete of protective layers of peripheral longitudinal bars in the cross section of the column is not separated; the parting positions refer to at least one vertical slot which appears in the reinforced concrete column along the interface of the separation material and the concrete along with the increase of load; and the separation material is a sheet material.
Description
Technical field
Self adaptation divides scapus to belong to the reinforced concrete structure technical field, relates in particular to a kind of pillar and manufacturing approach thereof that is applicable to multilayer, high-level structure.
Background technology
In steel concrete multilayer and high building structure, because the restriction of function of use requirement and ratio of axial compressive force to axial compressive ultimate capacity of section etc. often form short column even ultrashort post in structure.The destruction of Reinforced Concrete Short generally is shear failure or bond damage, all is the very poor brittle fracture of ductility, and destructive process is of short duration suddenly, and it is very little to consume energy, and in earthquake, is easy to cause structural damage even collapses.
In order to improve the particularly anti-seismic performance of utmost point short column of short column, a kind of minute scapus appearred, promptly pillar is separated into the assembly of several pillars with barrier material, the ratio of shear span to effective depth of section of each pillar is bigger, thereby improves the anti-seismic performance of pillar.Divide the cross section of the barrier material perforation pillar of scapus, functional performance is affected, and the ratio of rigidity integral post of normal operational phase is little.
Self adaptation divides the barrier material of scapus not connect the pillar cross section, therefore shows as integral post in normal operational phase.Along with the raising of horizontal loading, self adaptation is divided the scapus experience evolution process from integral post to minute scapus: load hour, pillar is in elastic stage, shows as the mechanical characteristic of integral post, rigidity is big; Along with load increases; Pillar is along sheet material and the concrete perps that occurs at the interface; Perps width, length is along with the increase of pillar sidesway increases gradually, the process of the carrying out difference of different parts perps, and perps has according to the stressed automatic appearance of pillar and changes the characteristics of condition; After reaching the peak value bearing capacity, the condition of perps tends towards stability, and pillar is divided into the branch scapus, has improved the ductility and the energy dissipation capacity of pillar greatly.Self adaptation divides scapus that short column or ultrashort brittle shear of living are destroyed the ductile fracture that changes the branch scapus into, and the pillar anti-seismic performance is significantly improved
The utility model content
The purpose of the utility model provides a kind of reinforced-concrete post with self-adaptive parting function, can improve the ductility of short column or ultrashort post, improves its stress performance.
The utility model is characterised in that it is integral post that said self adaptation is divided scapus; Contain a steel concrete arrangement of reinforcement unit and barrier material; Barrier material only accounts for the part in pillar cross section, and its size is no more than pillar cross-sectional perimeter stirrup, and main effect is to weaken concrete section; The topping place concrete of the vertical muscle of periphery in the pillar cross section is not separated out, and the concrete of pillar is an integral body; Pillar cross-sectional perimeter stirrup is continuous.Said steel concrete arrangement of reinforcement unit is made up of two or four uniform section body arrangement of reinforcement subelements; Said barrier material is that the parting position of in said steel concrete arrangement of reinforcement unit, setting is vertically arranged; And be arranged between the uniform section body arrangement of reinforcement subelement; Said parting position is meant along with load increases in described reinforced concrete column along described barrier material and concrete at least one perps that occurs at the interface; Pillar is divided into 2 uniform section unit posts at least, and said barrier material is a sheet material, and said sheet material is metal sheet or fibre reinforced composites (FRP) plate or high molecule plastic thin plate or similar materials such as gypsum plank or plank.In order to adjust the pillar performance, in needs, can hole-opening on barrier material.
Along with load increases, said self adaptation divides scapus to change the less whole cross section post of ratio of shear span to effective depth of section into ratio of shear span to effective depth of section bigger branch scapus, thereby has improved the ductility when pillar destroys significantly.
The utility model self adaptation divides the manufacturing approach of scapus to summarize as follows:
(1) stirrup and the vertical muscle that self adaptation is divided two or four unit posts of scapus formed in colligation;
(2) the unit intercolumniation after placing colligation to finish barrier material, barrier material only accounts for the part of self adaptation split column section, and size is no more than pillar cross-sectional circumference stirrup, and above-mentioned barrier material adopts sheet material;
(3) the peripheral stirrup of colligation encloses bundle together with all unit posts;
(4) template is fixed on the cage of reinforcement periphery;
(5) concreting and guarantee concrete compaction;
(6) concrete is carried out maintenance, promptly make self adaptation after the form removal and divide scapus.
The utility model compared with prior art has following advantage:
(1) the utility model self adaptation is divided ductility and the energy dissipation capacity that scapus can significantly improve short column and ultrashort post, improves its anti-seismic performance.
(2) the utility model self adaptation divides scapus to be whole cross section post in normal operational phase, and rigidity is big, and functional performance is good.
(3) the utility model self adaptation split base for post does not originally increase difficulty of construction and cost.
Description of drawings
Fig. 1. the utility model self adaptation split column section figure, 1 is barrier material, and 2 is the unit post, and 3 is the peripheral stirrup of pillar, 4 unit tie muscle;
Fig. 2. the utility model self adaptation is divided peripheral stirrup of scapus and unit tie muscle structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
In the drawings, the utility model self adaptation is divided scapus to be separated material 1 and is divided into 4 uniform section unit posts 2, and " seismic design provision in building code " (GB50011-2010) regulation of 6.3.7,6.3.8 and 6.3.9 bar is satisfied in the vertical muscle of each unit post 2 and the configuration of stirrup 4.Barrier material 1 is for being sheet material, and its size is no more than the peripheral stirrup 3 of pillar.The peripheral stirrup 3 of pillar encloses the concrete of bundle 4 unit posts 2 and whole pillar.The utility model self adaptation is divided the concrete of scapus not to be separated material 1 and is separated fully, and the concrete of 4 unit posts 2 links together outside topping and barrier material 1 scope.
Self adaptation is divided ratio of shear span to effective depth of section≤2 pillars in frame construction, frame shear wall structure and the frame supported shear wall structure that scapus is applicable to the earthquake zone.
The utility model self adaptation divides the manufacturing process of scapus following:
(1) the vertical muscle of colligation unit post 2 and stirrup 4, the vertical muscle of each unit post 2 adopts symmetric reinforcement, and " seismic design provision in building code " (GB50011-2010) regulation of 6.3.7,6.3.8 and 6.3.9 bar is satisfied in the configuration of vertical muscle and stirrup 4.
