Description
Technical field
The utility model relates to a kind of H steel column flush type column foot connecting structure.Belong to building field, be applicable to being connected of H steel column and reinforced concrete foundation.
Background technology
Steel work is made as the master with steel, is divided into light steel and heavy steel, is one of main building structure.Because its intensity is high, from heavy and light, integral rigidity is good, deformability is strong, material is even, isotropism is good, good toughness, industrialization degree advantages of higher, and good antidetonation and stress performance, in the engineerings such as highrise building and factory building, obtain increasingly extensive application.
Steel work integral body comprises top-out main body and lower post leg structure, although it is less that the suspension column structure accounts for the ratio of monolithic architecture structure, but suspension column is the important node that firm structure middle and upper part structure is connected with concrete foundation, it is the final Force transmission parts of whole steel structure system, it is the principal element that determines its bearing capacity, play an important role in structure, so the design of suspension column structure concerning the integrally-built safety in top, is the key in the structural steel design.
The suspension column pattern depends on the section form of post and the connected mode on post and basis.Post is divided into and rigidly connects and hinged two kinds of forms with the connected mode on basis.Suspension column can only transmit vertical counter-force when suspension column was hinged, and under earthquake and the horizontal loads, suspension column often is subject to very large bending and shearing, modern high-rise steel structure building is because stressed larger at the bottom of the post simultaneously, rigidly connect suspension column under the similar operating mode and use comparatively extensively, that the connected mode that rigidly connects suspension column and concrete foundation can be divided into is exposed, outer-enwraped type and flush type.
Good integrity, the bearing capacity of flush type suspension column are large, and the flush type suspension column contacts power transmission by shaft with concrete.Generally speaking, when being subject to shearing at the bottom of the post, the contact-segment of pile body and concrete foundation can provide enough shearings resistance, but in some cases, shearing resistance is not enough, when upper axis power is delivered to base plate, usually can cause the beneath concrete local failure of base plate.Usually occur the problems such as lifting difficulty, the easy off normal in installation site, verticality are inadequate in the simultaneously H steel column construction, affect the stressed and load-carrying properties of H steel column.
In sum, the H steel column has good stressed and load-carrying properties, in engineering practice, obtain increasingly extensive application, the research of China's steel work concentrates in the research to superstructure, structural element and overall performance mostly, and relative less for the research of the steel column pin stress performance that links to each other with the basis and syndeton form.Need badly at present a kind of off normal that can effectively control the H steel column of invention, easy for installation, suspension column and basic switching performance good, can overcome suspension column concrete foundation office and crush bad H steel column flush type column foot connecting structure.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, invent that a kind of construction hoisting is convenient, speed of application is fast, the position is accurate, verticality is high, good with basic switching performance, can crush bad H steel column flush type column foot connecting structure with basic cooperative bearing and the office of avoiding.
In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:
A kind of H steel column flush type column foot connecting structure, it is characterized in that imbedding reinforced concrete foundation part two wing plate outside vertical in sidewall uniform welding peg at the bottom of the H steel column post, suspension column arranges the suspension column base plate, the expansion backing plate is set under the suspension column base plate, enlarge on the backing plate location floor is set, H type shear key is symmetricly set on the H steel column two wing plates outside, arranges stone bolt in suspension column base plate scope.
Aforesaid H steel column flush type column foot connecting structure is characterized in that suspension column base plate, expansion backing plate, positioning rib sheet material matter are steel plate.
