Description

Double spiral stirrup combined with steel mesh structure

technical field

The utility model relates to a spiral hoop structure; specifically, the utility model relates to a structure of multiple spiral hoops combined with a steel mesh, which has the effect of temperature ribs.

Background technique

In the known reinforced concrete design structure, in order to enhance the earthquake resistance of the structure, stirrups are generally used to enclose the steel bar and the concrete, so that the steel bar and the concrete can still be effectively combined during the earthquake process, thereby enhancing the earthquake resistance of the structure.

Taiwan is located in a geographical location with frequent earthquakes, which is very important for the building strength to resist tensile and shear forces. In the design of steel-reinforced concrete, steel reinforcement is mostly used as the main component for load-bearing, tensile and shear resistance. Afterwards, steel bars and stirrups are added around the steel frame to share the force of the steel frame, increase the adsorption force of the concrete, and reduce the resonance when the lateral force is applied. However, in the current steel-reinforced concrete design, the design and application of the reinforcement part are relatively simple, which is difficult to meet the actual design and construction requirements. In addition, limited by the manufacturing technology and assembly technology of the spiral stirrup, under a reasonable design, the strength that a single spiral stirrup can provide is still limited.

In view of this, in order to improve and solve the above-mentioned shortcomings, the utility model proposes a utility model with a reasonable design and effectively improves the above-mentioned deficiencies through deep thinking research and cooperation with the operation of academic theories.

The plurality of first tangential reinforcing bars are not connected to each other. Generally speaking, the arrangement of the first tangential reinforcing bars is parallel to each other; however, it can also be adjusted according to the construction environment and site needs. Therefore, the plurality of first tangential reinforcing bars must be cross-fixed via at least one axial bar to form the first side reinforcing mesh. Among them, generally speaking, the axial reinforcement is vertically cross-connected with the first tangential reinforcement. If the strength of the overall structure is not affected, the mutual arrangement can also be adjusted according to the construction efficiency requirements.

The middle part of the steel mesh on the first side can be tangent to the circumference of the first spiral hoop and the second spiral hoop respectively, and its two bent parts are respectively inserted into the circumference of the first spiral hoop and the second spiral hoop, thereby increasing the concrete confinement A large surface area makes it difficult for steel bars and concrete to separate during earthquakes, thereby enhancing the rigidity of the structure.

But add the second side reinforcement mesh that is arranged on opposite first side reinforcement mesh, promptly form the multiple spiral stirrup of the present utility model combined with reinforcement mesh structure, can greatly increase the surface area of side confinement concrete, make reinforcement and concrete shear It is not easy to separate under the action of force, thereby enhancing the relative toughness of the structure.

In addition, both the first side reinforcement mesh and the second side reinforcement mesh are inserted into the first gap and the second gap of the first spiral hoop and the second spiral hoop, in other words, the two bends of the first side reinforcement mesh and the second side reinforcement mesh The folded part is not in direct contact with the first coil and the second coil; however, appropriate adjustments can be made to meet different structural requirements or material designs.

The utility model provides a compound spiral stirrup combined with steel mesh structure, which is formed by combining spiral stirrups and mesh bars of different sizes and shapes, which can increase the confining force and strengthen the rigidity of the overall structure, and can be used as a grouting forming structure body skeleton.

In the utility model, the first spiral hoop 200, the second spiral hoop 300 and the first side steel mesh 400 can preliminarily form a compound spiral hoop combined with a steel mesh structure 100, which is already more stable than the skeleton formed by a single spiral hoop . If the second side reinforcement mesh 500 arranged on the opposite first side reinforcement mesh 400 is added, the double spiral stirrup combined with the reinforcement mesh structure 100 of the present invention can be formed, which can greatly increase the surface area of the side confining concrete, and make the reinforcement and the reinforcement mesh Concrete does not easily separate under shear forces, thereby enhancing the relative toughness of the structure.

However, the above-mentioned included angles can also be adjusted according to the requirements of different design structures. As shown in the top view 3b of the embodiment, the bent side 422 is opposite to the side branch 522 of the vertical bottom branch 521.

Moreover, the side branch 522 of the second tangential reinforcing bar 510 opposite to the first tangential reinforcing bar 410 is also opposite to the bent side 422 . In other words, the side 422 adjacent to the bent side 422 and the opposite side branch 522 must be perpendicular to the middle portion 421 or the bottom branch 521 . This design makes the double spiral stirrup combined with the steel mesh structure 100 have the characteristics of temperature bars, which makes the shrinkage stress larger and can cover more concrete surface area.
