Description
Technical field
The present invention relates to a kind of building structure technology.Specifically related to prefabrication and assembly construction concrete structure technique.
Background technology
At present building, in bridge structure, precast concrete is connected with following manner：Connect prefabricated by Cast-in-Situ Segment
Component and prefabricated components are connected by shear connector.
It is most common way in concrete component by set Cast-in-Situ Segment to connect prefabricated components；It is hinged by shearing prefabricated
Component is more suitable for the connection between Prefabricated steel construction component and concrete component.The mode of both connection prefabricated components has two
Feature, first, the joint is consolidation, and larger moment of flexure can be produced at this after malformation；Second, the joint connects A, B component
It is integrated, it is difficult to change one of component.
Current architecture configuration development trend is standardization, factory prefabricating, so not only improves guarantee construction quality, and energy
Enough speed up the work and reduce cost.
When prefabricated components are concrete component, relation is hinged for reliable structure needs component again between, and requires
When portion's structure is replaceable, prior art is just difficult in adapt to.
By taking Fig. 1 as an example, prefabricated freely-supported cover plate is installed on wall, when loaded vehicle passes through, produces very big active earth pressure,
Causing structure wall has diagram deformation tendency, and the optimal path for solving the problem is exactly that setting can between prefabricated cover plate and wall
The hinged structures leaned on, disadvantageous deformation is resisted by opposite side passive earth pressure.
The content of the invention
It is an object of the invention to provide a kind of hinged structures suitable for prefabricated concrete structure, to solve to work as prefabricated structure
When part is concrete component, relation is reliably hinged between structure needs component, and structure wall is indeformable, and superstructure is replaceable
Etc. technical problem.
In order to realize foregoing invention purpose, the technical solution adopted in the present invention is as follows：
A kind of hinged structures suitable for prefabricated concrete structure, including prefabricated components A, prefabricated components B and pre-buried spiral shell
Bar；
Prefabricated components B needs to set the reserved circular hole of prefabricated components B, and circular hole size is according to pre embedded bolt specification and prefabricated peace
Dress precision determines；Pre embedded bolt bottom is embedded in prefabricated components A, and its top passes through the pre-buried circular hole, pre embedded bolt top
Fixed by billet and nut, screw rod specification and pre-buried depth determine that the screw rod bears axial tension according to stress size；In advance
Component A processed and prefabricated components B is rotatable by axis of concavo-convex notch, and as hinged structures, the notch bears horizontal shear；
Concavo-convex notch is set between prefabricated components A and prefabricated components B lap-joints, and angle is spent in notch slope into certain；It is described recessed
Notch top surface multilayer oil felt pad is set between tongue mouthful；One end can only laterally set a row hinge and connect structure in same prefabricated components B
Make, multiple hinged structures can be set in a row, and this row must on the same line, and the straight line is exactly structure hinge rotary shaft
Line.
A kind of hinged structures suitable for prefabricated concrete structure, the width of rebate is prefabricated components A width
1/3rd；Notch slope is into 45 degree of angles；Thickness a thirtieth of the multilayer oil felt pad gross thickness not less than prefabricated components A,
And the malthoid number of plies is no less than three layers.
Advantages of the present invention is as follows：
The inventive structure is simple, cheap, convenient, hinged structures function reliability of constructing.It is not only convenient for installing, and just
In the replacing of prefabricated components.It is widely used in the concrete structures such as building, bridge, piping lane.
Brief description of the drawings
Fig. 1 is the deformation tendency schematic diagram that prefabricated freely-supported cover plate is installed to wall.
Fig. 2 is structural representation of the invention.
Accompanying drawing number：1 pre embedded bolt, 2 billets, 3 nuts, 4 concavo-convex notches, 5 multilayer malthoids, 6 stay circular hole, 7 loaded vehicle rows
Track, 8 ground, 9 active earth pressures, 10 wall deformation tendencies, 11 pre-buried cover plates, 12 passive earth pressures.
Specific embodiment
Structure of the invention is shown in Figure 2.
A kind of hinged structures suitable for prefabricated concrete structure, pre embedded bolt 1 needs to be embedded in component A, screw rod
Screw rod specification and pre-buried depth determine according to stress size.Prefabricated components B needs to set the reserved circular holes 6 of prefabricated components B, circular hole chi
It is very little to be determined according to screw rod specification and prefabricated installation accuracy.Screw tip is fixed by billet 2 and nut 3, billet size rule
Lattice according to preformed hole size and the determination of stress size, nut and bolt matching, tighten and do not loosen during installation by nut, it is not necessary to
Excessive pretightning force.Concavo-convex notch 4 is set between component A and B, and into 45 degree of angles, width of rebate is about the three of component A on notch slope
/ mono-.Notch top surface pad multilayer malthoid 5 is set between concavo-convex notch, and malthoid total thickness is not less than wall thickness 1/30.Same
One end can only laterally set row's hinged structures in prefabricated components B, and multiple hinged structures can be set in a row, and this row must
Must on the same line, the straight line is exactly structure hinge pivot center.
Based on features above, the working mechanism of structure hinge is：
1st, component A and component B is rotatable by axis of concavo-convex notch, as structure hinge；
2nd, the viscoplasticity feature of multilayer malthoid is suitable for the small changing of the relative positions and rotation between component A, B between concavo-convex notch；
3rd, when with causing prefabricated components B and the external force of the component A changing of the relative positions to increase, prefabricated components B has along notch slope
The trend of the upward changing of the relative positions, now screw rod generation pulling force, passively prevents the changing of the relative positions trend, and screw rod is subjected only to axle all the time in this configuration
To pulling force, shearing is not subject to, horizontal shear is received by tongue and groove mouthpiece all the time, and stress is clearly reliable.
Prefabricated components B of the invention is replaceable.
