Abstract
The utility model discloses a double-pre-buried-plate opposite-pulling-type built-in fitting and belongs to the technical field of building design construction. The double-pre-buried-plate opposite-pulling-type built-in fitting comprises an anchoring piece, a shear key and two side pre-buried plates. The two ends of the anchoring piece are connected with the two side pre-buried plates. The shear key is connected with the inner side of the pre-buried plate on one side. The outer surfaces of the pre-buried plates are flush with the outer surface of a concrete structure component. The double-pre-buried-plate opposite-pulling-type built-in fitting has the advantages that structure force transmission is clear and direct, welding joint quality is controllable, and the requirement for structure stress can be fully met. Meanwhile, the problem that the size of components such as a concrete structure beam or column cannot meet the requirement of the anchoring length of the built-in fitting is solved, and the shear capacity of the built-in fitting is greatly improved by adding the shear key.
Description
Technical field
The utility model relates to steel and concrete structure building member, specifically relevant to pull-type built-in fitting with a kind of pair of embedded board.
Background technology
Steel-concrete combined structure is a very fast direction of Structural Engineering field development in recent years, and countries in the world have been successfully applied to combining structure a lot of super highrise buildings and Loads of Long-span Bridges.And along with China's economic construction fast development of nearly more than 20 years, steel-concrete combined structure has also obtained development rapidly and application more and more widely in China, range of application has related to the fields such as building, bridge, tall and slender structure, underground structure, structural strengthening.Engineering application attestation, combining structure combines the advantage of steel work and concrete structure, can obtain good structural performance by traditional construction method and simple construction technology.Technical economic benefit and social benefit are remarkable, are applicable to very much the national conditions of China's present stage infrastructure, are one of new structure systems having broad prospect of application.
Steel-concrete combined structure is a kind of new structure growing up on steel work and reinforced concrete structure basis, now be widely used in the engineerings such as high-rise super highrise building, Loads of Long-span Bridges and subway tunnel, become the fifth-largest structure arranged side by side with conventional concrete structure, masonry structure, steel work, wooden construction.
In present stage steel-mixed combining structure, being connected mainly between steel work and concrete structure is connected by built-in fitting, develop rapidly along with China's economy, structure presents towards higher, the trend of large span, more special-shaped future development more, the load that steel work and concrete structure connected node transmit is increasing, dowel quantity and diameter specifications get over increase, this has just brought collaborative work capability problems between embedded part and concrete structure, the problem of dowel anchorage length.Between this present situation, the utility model uses and gives birth to.
Utility model content
In order to overcome deficiency of the prior art, the utility model provides a kind of power transmission direct, and Path of Force Transfer clear and definite is constructed convenient, and welding quality has controllability, and the high two embedded boards of node strength are to pull-type built-in fitting.Solve the problem that the scantlings such as the concrete structured beam that is connected with built-in fitting or post cannot meet built-in fitting anchorage length, by adding shear key, greatly improved the shear resistance of embedded part.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
Pair embedded board, to a pull-type built-in fitting, comprises anchoring piece, shear key and both sides embedded board; Anchoring piece two ends are connected with both sides embedded board respectively, and shear key is connected with a side embedded board inner side, and embedded board external surface flushes with concrete structure member external surface.
Described anchoring piece is dowel, by perforation plug welding mode, is connected with both sides embedded board.
Described anchoring piece is crab-bolt, and the mode that is bolted is connected with both sides embedded board.
Described shear key is connected with a side embedded board inner side by fillet weld.
Described shear key can be selected angle steel, H shaped steel, channel-section steel form.
Adopt after such scheme, the utlity model has many beneficial effects:
(1), solve built-in fitting anchoring piece anchorage length problem.By embedded board is set in embedded part both sides simultaneously, therefore anchoring piece length just can be determined according to the actual requirements, and need not be subject to anchoring piece length restriction, solve the problem of anchoring piece anchorage length deficiency, to reaching the coefficient target of embedded part and concrete structure.
(2), ultimate bearing capacity of joints is high.In the utility model, clearly, directly, weldquality has controllability in embedded part power transmission, and bearing capacity is high, has greatly improved the shear-carrying capacity of embedded part by adding shear key.
(3), can form standardized production.
Accompanying drawing explanation
Fig. 1 is the elevation of the utility model preferred embodiment;
Fig. 2 is the top view of the utility model preferred embodiment;
Fig. 3 is the left view of the utility model preferred embodiment;
Label declaration wherein: 1-anchoring piece, 2-shear key, the pre-embedded board of 3-, the 4-plug welding of boring a hole, 5-fillet weld.
The specific embodiment
By reference to the accompanying drawings, to the utility model, preferred embodiment is described in further details.
The built-in fitting of the present embodiment as Figure 1-3, comprises anchoring piece 1, shear key 2 and embedded board 3.
Embedded board 3 is two, is oppositely arranged, and embedded board 3 external surfaces flush with concrete structure member external surface.Between two embedded boards 3, by anchoring piece 1, connect.In the present embodiment, anchoring piece 1 has 8, forms 4 row and arranges.Have the form that anchoring piece 1 in the utility model can adopt dowel, dowel is connected with two embedded board 3 inner sides by perforation plug welding mode.During site operation, left side embedded board 3 and being connected of dowel be right side embedded board 3 is on-the-spot install after, before concreting, connect passing on left perforation plug welding mode again.
Anchoring piece 1 can also be the form of crab-bolt in addition, by bolt, is connected with embedded board 3, forms drawing the form of crab-bolt.The scene of built-in fitting is installed more convenient like this.
Above-described embodiment is only for the inventive concept of the present utility model of explaining; but not restriction to the utility model rights protection; allly utilize this design to carry out the change of unsubstantiality to the utility model; such as form and the quantity of anchoring piece 1 and shear key 2 are done suitable adjustment etc., all should fall into protection domain of the present utility model.
