Abstract
The utility model relates to a civil engineering structure, in particular to a connected node of a steel girder and a combined steel and concrete column. The connected node comprises the steel girder and the combined steel and concrete column; a sleeve formed through the end-to-end welding of a prefabricated steel plate is sleeved on the combined steel and concrete column; and a fixed plate at the end part of the steel girder is connected with the prefabricated steel plate forming the sleeve through a bolt. Therefore, the limit value of the axial compression of the column can be effectively increased, the sectional dimension of the column is effectively reduced, the building use space is increased, a short column can be prevented from occurring, the arrangement number of shear connectors at a column end is greatly reduced, the cost can be effectively reduced, and the construction progress is speeded up. The utility model is suitable for components in the form of different sections such as the T-shaped section, the L-shaped section, the cross section and the like as well as different types of components such as the column, the shear wall embedded column, the irregular column, the short-pier shear wall embedded column and the like; and in addition, the construction difficulties caused by concrete pouring in a core steel pipe concrete structure are avoided.
Description
Technical field:
The utility model relates to civil engineering structure, especially a kind of girder steel and steel reinforced concrete column jointing gusset.
Background technology:
Main application is reinforced concrete structure in China's industry and civilian construction, comprise the high-level structure that individual multistory frame of extensive use in the past and nearly more than ten years rise, steel work is applied to the industrial premises structure more, but because the fault in material of concrete and formed steel construction self, and along with the development of China's economic society, for the raising day by day of the instructions for use of building function, constructional materials is analyzed less, it is very few to make the concrete filled steel tube slab column system use in civil high-rise buildings.Critical problem is being connected of steel core concrete column and concrete slab, i.e. slab-column connections problem in concrete filled steel tube slab column system design.For concrete filled steel tube slab column system slab-column connections, owing to be that steel is connected with concrete, the continuity that is not so good as whole steel work or cast-in-place concrete structure is good.If produce deformation at this position, then its joint behavior no longer is a rigidity, must have influence on the stress performance and the deformation of total system.
Summary of the invention:
Technical problem to be solved in the utility model is: provide a kind of rational in infrastructure, the working strength height is stablized firm girder steel and steel reinforced concrete column jointing gusset.
The technical scheme that solves its technical problem employing is:
A kind of girder steel and steel reinforced concrete column jointing gusset, comprise section steel beam, combined steel and concrete column, be set with the sleeve that is welded into from beginning to end by prefabricated steel on the described reinforced concrete post, the fixed head of described section steel beam end is connected with the prefabricated steel bolt that constitutes this sleeve.
Compared with prior art, the beneficial effects of the utility model are:
(1) relative reinforced concrete structure can effectively improve the axis of a cylinder pressure limit, effectively reduce column cross-section size, increases the building usage space, and can avoid the appearance of short column; Because shaped steel mainly is configured in column section nuclear core, can effectively improve the post shear resistant capacity simultaneously, effectively improve the ability of elastic-plastic deformation and the ductility of frame construction post, be very beneficial for the anti-ability of collapsing of structure.
(2) adopt girder steel and steel reinforced concrete column jointing gusset structure can effectively reduce the structure building cost; Secondly because the shaped steel sectional dimension is less; simultaneously because the shaped steel sectional dimension is less; the shaped steel protective layer thickness is relatively large; therefore the cementation between shaped steel and the concrete can effectively improve; make structure under geological process, have ductility preferably; and can reduce the quantity that is provided with of styletable shear connector greatly, can effectively reduce cost and accelerating construction progress.
(3) adopt girder steel and steel reinforced concrete column jointing gusset structure to have extraordinary fireproof performance, can effectively reduce the cost of fireproof paint; Joint structure is simpler.
(4) girder steel and steel reinforced concrete column jointing gusset structure are more flexible on section form, be suitable for different cross section form member and dissimilar members such as post, shear wall sleeper, hetermorphiscal column and shear wall with short piers sleeper such as T shape, L shaped and cross, and many constructional difficulties of having avoided core encased structures fluid concrete to bring.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model structure vertical view.
Among the figure: section steel beam 1, reinforcing bar 2, combined steel and concrete column 3, reinforcing bar 4, prefabricated steel 5, fixed head 6, bolt 7.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to accompanying drawing, a kind of girder steel and steel reinforced concrete column jointing gusset, comprise section steel beam 1, combined steel and concrete column 3, be set with the sleeve that is welded into by prefabricated steel 5 head and the tail on the described reinforced concrete post 3, the fixed head 6 of described section steel beam 1 end is connected with prefabricated steel 5 bolts that constitute this sleeve.
Welding between the reinforced concrete post prefabricated steel 5 among the embodiment, when building structure is normally used, because prefabricated steel 5 is evenly distributed on node steel plate inboard, can play effective increase working strength and good stable to node, when node was changed, girder steel fixed head 6 can be according to adjusting at any time, to adapt to the instructions for use of different nodes, and then reach working strength height, stable performance.When floor relatively moves,,, node can not tilt to such an extent as to being kept relative stability because the bolt of 6 settings of reinforced concrete post 3 and girder steel fixed head produces relative pulling force.Prefabricated steel 5 and 6 actings in conjunction of girder steel fixed head utilize mutual constraint to prevent the node area cracking destruction; In girder steel and steel reinforced concrete column jointing gusset, frame construction is subjected to vertical and two kinds of load actions of level, incipient crack stage when operate as normal, nuclear core district steel plate all is in elastic stage, stress distribution is even, and when the node entire crack, nuclear core district prefabricated steel 5 principal strains reach yield strain substantially.Thereafter, district's prefabricated steel 5 strains of nuclear core increase rapidly, enter strain. in the main stretching strain of each stage center core district prefabricated steel always greater than main compressive strain, its reason is that nuclear core district prefabricated steel 5 is under the tension and compression state, being different from clean steel node nuclear core district prefabricated steel 5 tension and compression stress bears by self, but in the pressurized direction, concrete is resisted a part of compressive stress, therefore, district's prefabricated steel 5 stretching strains of nuclear core are greater than compressive strain, and the web overstrain is bigger when the concrete fragmentation unloads later on; Because embedded prefabricated steel 5 mainly is configured in column section nuclear core, can effectively improve the post shear resistant capacity, effectively improves the ability of elastic-plastic deformation and the ductility of frame construction post, has increased the anti-down ability of collapsing of structure.
