[0027] During implementation, please refer to Figure 4 、 Figure 5 、 Figure 6 which shows an embodiment of the present utility model.
[0028] This embodiment Figure 4 Figure 5 provides a shear wall closed horizontal reinforcement structure, including steel bars. The two ends of the steel bars have hook portions X402. The steel bars are bent multiple times to form a closed horizontal reinforcement X400. The closed horizontal reinforcement X400 has a cavity structure K4, and the hook portions X402 are located in the cavity structure K4.
[0029] In this embodiment, the closed horizontal reinforcement X400 is integrally formed by using a bending machine to bend the steel bars. This is a conventional operation of the prior art, and the specific model of the bending machine is not limited here. The cavity structure K4 is used to set the longitudinal reinforcements Z2 and Q3, and the hook portions X402 are used to hook the longitudinal reinforcements of the wall columns. Since the closed horizontal reinforcement X400 is formed by one steel bar, it is not easily damaged when being disturbed. The present utility model reduces the reinforcement ratio and has high construction efficiency.
[0030] This embodiment Figure 6 The closed horizontal reinforcement X500 is formed by bending and combining two groups of horizontal reinforcements. The connection ports form a whole inside the cavity of the shear wall K4, with more uniform force and more convenient construction, and it is suitable for longer shear walls.
[0031] In the prior art, there are three types of conventional shear wall horizontal reinforcement structures, which are respectively Figure 1 、 Figure 2 、 Figure 3 , and the horizontal reinforcements are separately arranged;
[0032] Figure 1 is composed of two end columns Z1 and the cavity structure K4; Z1 is respectively composed of the longitudinal reinforcement Z2 and the stirrup 112, and the cavity K4 is formed by tying the horizontal reinforcements 100 on both sides of the shear wall and the longitudinal reinforcement Q3. The horizontal reinforcement 100 of the shear wall is bent into a 90-degree horizontal reinforcement 101° and buckled into the cavity of the column Z1.
[0033] Figure 2It is a cavity structure K4; the longitudinal bars are Z2 and Q3, and the horizontal bars of the shear wall are U-shaped horizontal bars 200 and straight bars 201. The U-shaped horizontal bars 200 of the shear wall are continuously bent at two 90° to form a U shape; the U-shaped horizontal bars 200 are closely attached to the outside of the longitudinal bar Z2 and are tied and formed with the straight bar 201.
[0034] Figure 3 Two ends of the two horizontal bars 300 of the shear wall are bent into 135° hooks 301 to form a cavity structure K4; after being bent at 90° at the end, it is bent at 135° once and buckled to the longitudinal bar Z2, and the shear wall longitudinal bar Q3 is placed inside and tied and formed.
[0035] In this embodiment Figure 4 Figure 5 The closed horizontal bar X400 is integrally formed, and there is no connection port on the outer ring, forming a whole, with more uniform force, and can bear the in-plane bending moment of the wall. Therefore, the present utility model also has better seismic performance.
[0036] In some embodiments of the present utility model, the above-mentioned closed horizontal bar X400 has five bending parts, including three 90° bends X401 and two 135° bends X402. The five bending parts are all in arc transition. Such a setting reduces the dead angle between the closed horizontal bar X400 and the longitudinal bar Z2, making the closed horizontal bar X400 and the longitudinal bar Z2 more fitting.
[0037] In this embodiment Figure 6 The closed horizontal bar X500 is formed by bending two groups of horizontal bars through bends X501 and X502. The connection port forms a whole inside the cavity of the shear wall K4 and is tied and formed with Q3, with more uniform force, and is suitable for use in shear walls with larger lengths.
[0038] In order to make the present utility model create greater value, when the three specifications and spacings in the prior art are the same, the present utility model can be used instead.
[0039] For those skilled in the art, it is obvious that this application is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic characteristics of this application, this application can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of this application is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in this application. Any reference signs in the claims should not be regarded as limiting the claimed rights.
