Description
Technical field
The utility model relates to a kind of post ruggedized construction by increasing section, and particularly a kind of increasing section ruggedized construction of circular reinforced concrete post belongs to the fields such as building engineering, is applicable to the consolidation process of circular reinforced concrete post.
Background technology
Pillar is power transmission, primary structure member vertical in the building, bear vertical and level to load, its stress performance directly determines safety and the functional performance of building structure.In actual use, building uses Functional change, shockproof requirements to improve, design grade improves, built-loading increases, the reasons such as ratio of axial compressive force to axial compressive ultimate capacity of section does not meet the demands, structure overload, concrete aging, to cause the load-carrying properties of original pillar can not satisfy existing user demand, and may affect the safety of building structure, need to take the measure of matters to carry out consolidation process to former pillar.
The at present reinforcing and repairing measure for pillar mainly contains following several: (1) increasing section reinforcing method: improve its intensity by section area and the reinforcement ratio that increases member or building, rigidity, stability and crack resistance, construction technology is simple, improve larger to element bearing capacity, durability and fireproof performance are good, but exist the situ wet operation many, long construction period, original building is used the shortcomings such as impact is larger, sometimes also can cause because of the increase of dead load and must add reinforcing to the original structure basis, and not be suitable for the pillar that plain concrete member and Reinforcement reinforcement ratio are lower than the minimum steel ratio of existing national Specification.(2) add between steel column a staying: be in the post bottom or the post bottom adds the angle steel support simultaneously with top, supporting base end portion can adopt with being connected of post connecting portion post longitudinal reinforcement is dug out, vertical muscle two sides welding in additional short muscle and the post, again with junction plate and additional short muscle single-sided welding, and junction plate and the stiffened panel that supports be welded on the junction plate, steel is installed is at last supported, and use cement sand plaster.Add between steel column a staying and generally be applicable to pillar deflection, longitudinal strength, rigidity and the inadequate reinforcing of stability.The method operation is comparatively loaded down with trivial details, can't satisfy the needs of quick reparation.(3) reinforced with external steel encased: be with shaped steel at concrete four jiaos or two bread.Its advantage is that the sectional dimension of member increases seldom, and the bearing capacity of concrete column can have raising by a relatively large margin.Be applicable to not allow to enlarge markedly first sectional dimension of members, but require significantly to improve the reinforced concrete post of its supporting capacity.But steel using amount is larger, and cost is higher, and should not be in the high temperature place that is used in the unshielded situation more than 60 degree.Exterior glues the steel or sticking CFRP Sheet Strengthening Method are by construction structure glue affixing steel plate or the carbon fiber with special configuration in the concrete structure outside, to improve bending resistance, the shear behavior of structure, strengthen a kind of reinforcement means of structural safety.Generally be applicable to bear Static behavior and be in flexural member in the normal humidity environment, construction fast, the situ wet operation is few and reinforce after little to the structure appearance effects, be the wider reinforcement means of a kind of applicable surface.But consolidation effect depends on adhering process and operant level to a great extent, if there is larger potential safety hazard in the bonding insecure cracking phenomena that very easily occurs.
In sum, in engineering practice, often run into the reinforcing problem of old reinforced concrete post, overcome that existing reinforcing technique ruggedized construction globality is poor, newly placed concrete and former post concrete cooperative bearing weak effect, high in cost of production shortcoming, invent a kind of increasing section ruggedized construction of circular reinforced concrete post, have better economic technology benefit.
The utility model content
The purpose of this utility model is the applied in any combination by steel plate in steel plate in the transverse annular closure and the transverse annular closure, and the short steel plate of vertical anchor plate, shearing etc. is set, provide that a kind of speed of application is fast, the increasing section ruggedized construction of new-old concrete collaborative work and the circular reinforced concrete post that load-carrying properties are good, anti-seismic performance is good.
In order to realize above-mentioned technical purpose, the utility model by the following technical solutions:
A kind of increasing section ruggedized construction of circular reinforced concrete post is characterized in that at first digging the embedding hole of inboard strengthening steel slab, match board and tooth plate at circular reinforced concrete post reinforcing area;
Periphery at former circular reinforced concrete post reinforcing area, increase pile body is socketed respectively inboard hoop plate, outside hoop plate; Inboard strengthening steel slab end is welded in inboard hoop plate, and plate inserts the embedding hole of former circular reinforced concrete post; Outside strengthening steel slab penetratingly inserts increase pile body both ends and is welded in respectively inboard hoop plate, outside hoop plate;
Be evenly arranged more than one vertical anchor plate along former circular reinforced concrete post reinforcing area is elongated.
The increasing section ruggedized construction of aforesaid circular reinforced concrete post is characterized in that vertical anchor plate one side evenly arranges tooth plate, and tooth plate is imbedded in the embedding hole and by binder-reinforced.
The increasing section ruggedized construction of aforesaid circular reinforced concrete post is characterized in that medial and lateral strengthening steel slab central lines, and the interior extensions of center line intersect at the center of circle of post, evenly distributes more than one group in same cross section.
The structure that the utility model relates to has the following advantages and beneficial effect:
(1) the inboard evenly interval of vertical anchor plate arranges tooth plate, can avoid former steel concrete post in length and breadth to arrangement of reinforcement, tooth plate is implanted former reinforced concrete pile body, when vertical anchor plate installation and position were fixing during constructability, it was good to have improved new-old concrete collaborative work, carrying and anti-seismic performance.
(2) in outside hoop plate and the transverse annular closure the even interval of steel plate lay can avoid former steel concrete post in length and breadth to arrangement of reinforcement, simultaneously its separate type setting party construction and installing.
(3) setting of medial and lateral hoop plate, so that new-old concrete has good confined effect, the setting of collaborative inboard strengthening steel slab and outside strengthening steel slab, it is good to have improved new-old concrete collaborative work, carrying and anti-seismic performance.
