Abstract
The invention discloses a spiral rebar connector, and belongs to the technical field of constructional engineering. The spiral rebar connector is characterized by comprising a spiral rebar and lap-joint rebars, wherein the spiral rebar and the lap-joint rebars are fixed; the number of the lap-joint rebars is not less than 1; to-be-connected rebars are connected through grouting in the spiral rebar; and the lap-joint rebars are fixed on the spiral rebar to guarantee tensile properties of the spiral rebar connector. The spiral rebar has a restraint effect on grouting materials, thereby enhancing the interaction of the rebars and the grouting materials. The spiral rebar connector enables connecting areas to easily deform and coordinate with surrounding materials through small resistant-lateral rigidity and by adopting a mounting method of area grouting. The spiral rebar connector has the advantages of simple process, low cost, reliable performance and the like, is particularly suitable to connect rebars between assembled components, can be widely applied to assembled concrete structures, and has a wide prospect of engineering application.
Description
Technical field
The present invention relates to a kind of grouting connector for bar connecting between precast unit, belong to construction engineering technical field, be specially a kind of spiral reinforcement connector.
Background technology:
Prefabricated assembled concrete structure, as a kind of form of structure meeting industrialized production, has that speed of application is fast, labour intensity is low, noise pollution and an advantage such as wet trade is few and product quality is easy to control, is widely applied in countries in the world.The construction techniques of prefabrication and assembly construction is adopted effectively to economize on resources and the energy, improve material in the utilization rate realizing building energy conservation and strengthen in structural performance, overcome construction plant and ambient conditions to the restriction of site operation, reduce site operation labour scale, alleviate the harmful effect of building waste and Construction on Environment, improve building function and structural performance.Promote the Green Development requirement that prefabricated assembled concrete structure is conducive to realizing " four joint one environmental protection ", realize the building course of low energy consumption, low emission, can promote the sound development of Building Trade in China, realize predetermined target for energy-saving and emission-reduction, be the developing direction of China's future architecture.
But the connectivity problem of reinforcing bar is core and the difficulties of prefabricated assembled concrete structure always.
Metal grout sleeve is current most widely used fabricated construction connector, and great many of experiments and research prove itself to have the feature effectively transmitting axial load; But, recent numerous academic researches show, because the anti-side rigidity of metal sleeve itself is larger, the existence of the multiple connector of Nodes, make connector area rigidity comparatively large, cause the concrete of sleeve section and surrounding concrete to be out of shape and cannot to coordinate, be out of shape the crack produced and mostly concentrate on the overseas concrete of connector area, the mechanical property of material cannot be made full use of, be unfavorable for the anti-seismic performance of fabricated construction entirety.
Visible, current prefabricated member method of attachment also has certain technological deficiency, therefore, need a kind of connector, there is good tensile property and more soft anti-side rigidity simultaneously, can make reinforcing bar under seismic loading, meet the requirement of axial load effect, component can also be made in join domain compatibility of deformation.
Summary of the invention:
A kind of spiral reinforcement connector, is characterized in that, comprising: spiral reinforcement and overlap joint reinforcing bar; Described spiral reinforcement is fixed with overlap joint reinforcing bar; Described overlap joint reinforcing bar is no less than 1 reinforcing bar; Be in the milk connecting reinforcement in spiral reinforcement.
The application of described a kind of spiral reinforcement connector, is characterized in that: longitudinal hole is reserved in the side that prefabricated units needs connect, and to make spiral reinforcement connector connector insert, needs to be reserved with the reinforcing bar be partly connected in hole; Laterally reserving grout hole, to pour into grouting material in longitudinal hole; Spiral reinforcement connector is inserted longitudinal hole, and inserts the reinforcing bar that side is connected, then the reinforcing bar be connected by opposite side inserts connector, to be finally in the milk connection from the grout hole that component is reserved.
Beneficial effect is as follows:
A kind of spiral reinforcement connector of the present invention, utilize normal spiral muscle and plain bars to combine, cost is lower, and processing mounting process is simple, is applicable to batch production; The diameter of spiral reinforcement of the present invention is greater than and is connected bar diameter, is connected reinforcing bar and easily can inserts spiral reinforcement, and therefore, the present invention's construction is comparatively convenient.Overlap joint reinforcing bar of the present invention, can provide effective axial tensile property for connector, can meet the axial action of connecting portion; Meanwhile, the anti-side rigidity that spiral reinforcement is less can make connector area and adjacent material compatibility of deformation.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of a kind of spiral reinforcement connector of the present invention;
Fig. 2 is the A-A sectional drawing of Fig. 1;
Fig. 3 is one application schematic diagram of the present invention;
Wherein: 1-spiral reinforcement; 2-overlap joint reinforcing bar; 3-be connected reinforcing bar; 4-grouting material;
Detailed description of the invention:
When building structure needs the connection carrying out reinforcing bar between component, a kind of spiral reinforcement connector of the present invention can be used, to reach the mechanical property being not less than reinforcing bar and directly connecting.The present invention both may be used for the designed and calculated of new building, also can be used for the seismic hardening of existing building, as shown in Figure 1-Figure 3, wherein, Fig. 1 is the structural representation of a kind of spiral reinforcement connector of the present invention, and Fig. 2 is the A-A sectional drawing of Fig. 1, and Fig. 3 is one application schematic diagram of the present invention; Specifically comprise: 1-spiral reinforcement, 2-overlap joint reinforcing bar, 3-be connected reinforcing bar, 4-grouting material, M-lower end prefabricated units, N-upper end prefabricated units.
Wherein, spiral reinforcement fixedly can be no less than an overlap joint reinforcing bar, and the overlap joint reinforcing bar of a greater number can provide better tensile property and the binding effect to grouting material for connector;
Preferably, the cross-sectional area of all overlap joint reinforcing bars and mechanical properties of materials should be not less than the cross-sectional area and mechanical property that are connected reinforcing bar.
During use, can the side connected be needed to reserve longitudinal hole prefabricated units, to make connector insert, need in hole to be reserved with the reinforcing bar be partly connected; Grout hole can be reserved, to pour into grouting material in longitudinal hole horizontal; Connector is inserted longitudinal hole, and inserts the reinforcing bar that side is connected, then the reinforcing bar be connected by opposite side inserts connector, to be finally in the milk connection from the grout hole that component is reserved.
Because the connecting structure of prefabricated units also has various ways, therefore a kind of spiral reinforcement connector of the present invention also can make the change on part-structure according to dissimilar connecting structure, if these change or are out of shape still in claim of the present invention, then the present invention also comprises those changes or distortion automatically.
Claims (2)
1. a spiral reinforcement connector, is characterized in that, comprising: spiral reinforcement and overlap joint reinforcing bar; Described spiral reinforcement is fixed with overlap joint reinforcing bar; Described overlap joint reinforcing bar is no less than 1 reinforcing bar; Be in the milk connecting reinforcement in spiral reinforcement.
