Abstract
The utility model relates to a special-shaped column of steel plate reinforced concrete, which belongs to the technical field of special-shaped columns in civil engineering. The shape of the cross section of the special-shaped column is a section combined of more than two rectangles, and longitudinal bars (2) and hoping bars (3) are bound to form a steel frame with a rectangular section. The special-shaped column is characterized in that the steel frame is internally provided with a steel plate (1) and the steel plate is continuous and integral inside the whole special-shaped column. The two steel plates (1) are welded into one, the steel plate is provided with a reserved hole, the diameter of the reserved hole is larger than the diameter of the steel bar by 2 mm and the hooping bars (3) adopt U-shaped hoops, pass through the reserved hole on the steel plate and then are butt-welded into closed hoping bars.
Description
Technical field
The utility model relates to a kind of steel plate and strengthens concrete profiled pile, belongs to the special-shaped column structure technical field of civil engineering.
Background technology
Along with the improving constantly of living standard, people are more and more higher to the requirement of dwelling house condition in recent years.Compare with the ordinary construction dwelling house, the shaped rc columns frame construction can improve the architectural space utilization rate, increases the usable floor area in house, alleviates dead load, improves stock utilization etc.This structural system has obtained promoting comparatively widely and using in China, especially is used in housing construction.
It is to be solved that the application of special-shaped column structure system in high earthquake intensity area also has a lot of problems to have, and particularly the weakness that the shear-carrying capacity of bean column node under geological process is lower is particularly outstanding.At this problem, Chinese scholars has been made a lot of researchs, has proposed the measure of many reinforcement special-shaped column structures, but in actual conditions, because constructional difficulties and cost are crossed problems such as height, these measures can not obtain excellent popularization and use.
Summary of the invention
The utility model is improved special-shaped column structure at these problems.Under the various restrictive conditions of actual engineering, keep the original cross-sectional sizes of hetermorphiscal column, further improve the stress performance of its node, improve bearing capacity, improve ductility.And by numerical simulation, proved that the utility model can effectively strengthen the node of special-shaped column structure really.
Steel plate is strengthened concrete profiled pile, at plane section is in L, T, the criss-cross concrete profiled pile node, according to an amount of steel plate and the reinforcing bar of engineering actual conditions configuration, steel plate is in aggregates continuously in whole hetermorphiscal column node, vertical muscle of the peripheral configuration of steel plate and stirrup, be combined into cage of reinforcement by vertical muscle and stirrup, bear shearing together by steel plate, reinforcing bar and concrete.The hetermorphiscal column shape of cross section is two cross sections that above rectangle is combined into, and having formed the cross section by vertical muscle and stirrup colligation is the cage of reinforcement of rectangle, disposes steel plate in cage of reinforcement, and steel plate is in aggregates continuously in whole hetermorphiscal column.The central point of two steel plates at two rectangle intersection positions intersects, and is L, T, cross, and two steel plates are welded into a whole.Establish preformed hole on steel plate, the diameter of preformed hole is bigger 2 millimeters than bar diameter.Stirrup adopts U type hoop to pass the steel plate preformed hole, then to being welded into closed stirrups.
The beneficial effects of the utility model are: simple structure, easy construction has obviously improved special-shaped column structure bean column node bearing capacity and ductility.For example under steel ratio was 5% situation, the ultimate bearing capacity of joints of L, T, crisscross joint improved 48%, 47%, 58% respectively, and when beam surrender, node was examined the core district and cracking phenomena do not occurred.

The specific embodiment
Steel plate is strengthened concrete profiled pile, the hetermorphiscal column shape of cross section is two cross sections that above rectangle is combined into, having formed the cross section by vertical muscle 2 and stirrup 3 colligations is the cage of reinforcement of rectangle, configuration steel plate 1 in cage of reinforcement, and steel plate is in aggregates continuously in whole hetermorphiscal column; The central point of two steel plates 1 at two rectangle intersection positions intersects, and is L, T, cross, and two steel plates 1 are welded into a whole.Establish preformed hole on steel plate, the diameter of preformed hole is bigger 2 millimeters than bar diameter.Stirrup 3 adopts U type hoop to pass the steel plate preformed hole, then to being welded into closed stirrups.Reserve thickness of concrete cover in the cage of reinforcement outside then, a template; Build the post concrete again at the bottom of the beam.Prop up beam forms and wear the vertical muscle of beam; The casting beams board concrete is to back again.Bear shearing together by steel plate, reinforcing bar and concrete.
