Description

Structural end reinforcement system

This creation is about a steel reinforcement system, especially a steel reinforcement system applied to the end of a structure.

The strength of the reinforced concrete structure to withstand stresses such as tension, compression and shear is highly related to the design and configuration of the steel bars in the structure. In addition to increasing the diameter of the main reinforcement of the structure, it will also be added at the end of the main reinforcement. The upper anchoring structure, such as bending the end of the main bar into a right-angle shape or a hook shape, to increase the degree of adhesion between the steel bar and the concrete, and to improve the grip and anchoring force without separating the two from each other .

However, under the condition that the diameter of the main bar is larger, if the end of the main bar is welded with the same diameter as the main bar to strengthen the structure and increase the anchoring force, the larger diameter bar is made with the same curvature When the hook is used, the radius of curvature of the hook is larger, the welding length required is longer, and the space occupied will also become larger, which increases the difficulty of construction. Moreover, if the relative heights of the ends of the main ribs at different positions are not consistent, it will also affect the difficulty of anchoring. Therefore, how to anchor the end of the main bar with a relatively simple structure and construction method in a limited space is a technical problem to be solved.

In order to solve the above-mentioned conventional technical problems, one purpose of this creation is to provide a structural body end reinforcement system and a structural body using it, which can increase the convenience of construction under the premise of complying with relevant safety regulations.

One purpose of this creation is to provide a structural end reinforcement system and a structure using it, which can provide greater flexibility for the design of the structural end.

The embodiment of the present invention provides a structural end reinforcement system, which is suitable for reinforcement of the reinforcement column head of a structural body, and includes a first reinforcement and a plurality of second reinforcements. Each second steel bar is partially welded to the first steel bar, wherein the first steel bar has a first cross-sectional area, each second steel bar has a second cross-sectional area, and the first cross-sectional area of the first steel bar is not less than all the second steel bars welded The sum of the second cross-sectional area of the steel bar.

The embodiment of the present invention also provides a structure, including a structure body and the above-mentioned structural body end rebar system, the structure end rebar system is located in the structure body, and the second rebar is located at the end of the structure body for anchoring .

Based on the above, the structural end reinforcement system provided by the embodiment of the present invention has the following advantages:

By welding the second steel bar to the end of the first steel bar, the second steel bar can be used for anchoring without directly processing the first steel bar. This construction method does not need to change the first steel bar with a larger diameter, which is relatively simple .

Because the second steel bar with a smaller cross-sectional area is selected, when the end of the second steel bar is processed into a hook, the curvature of the hook can be increased, and the occupied space is therefore reduced. The space at the end of the structure can be reduced. When restricted, a certain degree of structural reinforcement is carried out, and the construction method is more flexible.

In view of the above-mentioned technical problems to be overcome, the embodiment of the present creation develops a structural end reinforcement system 10 to reinforce the strength of the structure to a certain extent when the space at the end of the structure is limited. , And the construction method is also more flexible.

The length of the upright portion 121 and the length of the welding on the first steel bar 110 can be adjusted according to the degree of reinforcement required and the spatial configuration, and are not limited.

In order to make the most effective use of the space in the end area of the first steel bar 110, the hook 122 of the second steel bar 120 is bent in a direction away from the axis of the first steel bar 110 to form the shape of the hook, reducing the number of different second bars. The influence between the hooks 122 of the steel bar 120. Moreover, the extent to which the top end of the hook 122 of the second steel bar 120 exceeds the top end of the first steel bar 110 can be selectively adjusted according to the size of the space above the top end of the first steel bar 110. In addition, whether the hook portion 122 exceeds the top of the first steel bar 110 or the excess length can be adjusted according to the size of the reserved part between the end of the upright column 100 and the top of the first steel bar 110. In this embodiment, each hook portion 122 exceeds the same length of the first steel bar 110; however, in different embodiments, each hook portion 122 may respectively exceed the first steel bar 110 by different lengths to provide structural design elasticity.

The aforementioned vertical column 100, for example, may be a reinforced concrete column. The vertical column 100 is combined with the structural end rebar system 10, that is, the vertical column 100, the first steel bar 110, and the second steel bar 120 to form a well-known building. The important structure of the steel, such as beams, columns, etc., and in the structure is the hook 122 of each second steel bar 120 to anchor the reinforced concrete column to increase the degree of adhesion between the steel bar and the concrete. Prevent the two from being separated due to force, thereby increasing the strength of the structure. Since the cross-sectional area A1 of the first steel bar 110 is not greater than the sum of the cross-sectional areas A2 of all the second steel bars 120 welded to the first steel bar 110, sufficient end anchoring strength can be provided.
