Description
Technical field
The utility model is related to the connection in building structural element field, particularly concrete prefabricated element and peg, specifically
It is applied to fabricated construction precast floor slab, beam, the connection between pillar and the connection between building superstructure and basis.
Background technology
Along with the fast development of assembled architecture industry, it has, and construction is convenient, and safe and reliable, anti-seismic performance is good, section
Many advantages, such as energy environmental protection, country is just in the building structure pattern of this environmental protection of iterative method.
Fabricated construction precast floor slab, beam at present, the connection between pillar is frequently with shaped steel, the connection side such as regular reinforcement
Formula, shaped steel shearing strength is fine, but its site operation is higher to welding technological level requirement, and difficulty of construction is larger, and steel using amount
Larger, regular reinforcement often take curved muscle form resist shearing, easy construction, but due to shearing direction be likely to be of uncertain
Property, the effect that curved muscle bends up effect there is also uncertainty, or even the situation being difficult to resist shearing action.
, as flexible shear connector, its range is very wide for peg, and common using method is that welding of peg exists
The outer surface of steel construction piece, such as steel pipe, the outer wall such as shaped steel, be then combined with concrete.
For assembled architecture industry, need the connected mode of more flexibility and reliability, beneficial to assembled in situ.
Content of the invention
The technical problems to be solved in the utility model is: provides a kind of steel and Combined concrete connecting elements, preparation technology
Process is simple, and the connected mode of peg is simple and reliable, functional, is particularly suitable for assembled in situ.
The technical solution of the utility model is as follows:
A kind of steel and Combined concrete connecting elements, including built-in fitting, described built-in fitting comprises the first end having through hole
Plate and the second end plate having through hole, are connected with, between described first end plate and the second end plate, the component possessing through hole, run through
Hole is connected with the through hole of first end plate and the second end plate, and described component longitudinal cross-section profile is in l shape or trapezoidal；In described through hole
It is placed with peg, in the cavity between peg and through hole, be filled with concrete.First end plate and the second end plate may be selected rectangle
Or circle slab, both parallel (for trapezoid cross section components) or vertical (for l tee section component).When actually used, will be pre-
Bury the beam of built-in fitting, after plate, post be transported to job site, then insert peg thereto, and casting concrete in cavity.
Described built-in fitting is steel components, such as engineering steel.
Described through hole is more than through hole external diameter with the cross section external diameter at first end plate through hole interface.At interface
The through-hole diameter group credit union of different through hole external diameters and first end plate brings peg and the concrete failure mode of multi-form,
So being that both external diameter diameter ratios need to calculate in advance in design.
The depth that described peg is inserted through hole is more than or equal to the half running through hole length.The length of embedment of peg will affect
The mechanical property of concrete and peg and failure mode in whole built-in fitting through hole.
Described longitudinal cross-section profile is in the through hole of l shape component, and the head depth of peg is not higher than the corner of l shape component
Place's height.The embedded mode that the special cross-section property of l shape component determines peg is different from trapezoid cross section, the head of usual peg
Embedment can give play to preferable switching performance below turning.
Described first end plate and the second end plate pass through to be weldingly connected with component.Whole built-in fitting can be that integral die-cast becomes
Type or using split welding by the way of connect.
Described peg includes that light is round and screw-type, the peg switching performance of different cross section diameter or different surfaces form
Difference, can select according to actual needs.
Described component outer wall uniform thickness, the component outer wall of usual built-in fitting is equal thickness, is easy to test and calculates outer wall thickness
The performance impact that concrete peg is connected.
The steel components that the utility model adopts and Combined concrete peg can be prefabricated in the factory, in fabricated construction structure
Carry out pre-buried during part making, arrive job site afterwards and install, convenient construction.
The utility model discloses a kind of steel and Combined concrete connecting elements, by concrete prefabricated in beam, plate, post etc.
Pre-buried above-mentioned built-in fitting in part, facilitates operation during assembled in situ, and the component of different cross section form can adapt to different demands,
Concrete grade due to filling in component can be different from the concrete grade outside component, further enhance the connection of peg
Performance.
