[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-4 As shown, a prefabricated component for prefabricated building walls includes a reinforcing cage 1 for a ring beam. The reinforcing cage 1 includes four main reinforcing bars 11 distributed diagonally along a rectangle, and also includes:

[0029] 5. A precast concrete wall 6 is fitted on top of it;

[0030] The steel hoop 3 is assembled on the steel plate 6 by fixing bolt 2. Every two steel hoop 3 form a group and are respectively inserted into two main steel bars 11 that are distributed in parallel on one side of the steel cage 1.

[0031] The channel steel component 4 is inserted into the insertion interface 34 opened on the two steel hoop components 3 of a set, and the slot of the channel steel component 4 is distributed facing the steel cage 1.

[0032] Specifically, in this embodiment, the steel plate 6 is pre-welded to the reinforcing mesh of the precast concrete wall 5, and after pouring, the steel plate 6 and the precast concrete wall 5 are integrally formed. Furthermore, combined with... Figure 1 and Figure 2 As shown, the precast concrete wall 5 is structurally divided into a main wall 51 and a narrow wall 52, with the cross-sectional thickness of the narrow wall 52 being less than that of the main wall 51. The narrow wall 52 is located within the main wall 51, and its connection to the outer wall facing the reinforcing cage 1 is a slope 53. Furthermore, a steel plate 6 is embedded and fixed to the narrow wall 52, and is on the same side as the slope 53. Moreover, the angle between the slope 53 and the narrow wall 52 is 145°-165°.

[0033] Furthermore, the height of the aforementioned reinforcing cage 1 is less than the height of the steel plate 6, while the height is... Figure 1 The vertical direction is shown. Because the steel plate 6 in the embodiment is part of the model for casting the ring beam, the integrity after casting is greatly increased.

[0034] In the above technology, the reinforcing cage 1 to be poured is arranged, and then the precast concrete wall 5 is fixed in advance. When the precast concrete wall 5 is prepared, a steel plate 6 is pre-embedded, and the steel hoop 3 is fixed to the steel plate 6 by fixing bolts 2. The installed steel hoop 3 is arranged in pairs along the vertical direction, and then the two steel hoop 3 are inserted by channel steel 4. Then, the two main reinforcing bars 11 on one side of the reinforcing cage 1 are inserted to the steel hoop 3. After fixing, the precast concrete wall 5 is used as part of the casting mold. After pouring, the precast concrete wall 5 and the ring beam form an integral whole.

[0035] As a further embodiment of the present invention, the steel hoop 3 includes a groove portion 31, and multiple notches 32 arranged in a linear array are provided on the end face of the groove portion 31, which completely penetrate the groove portion 31.

[0036] Specifically, in the embodiment, the slot 31 is inserted into the main reinforcing bar 11 of the reinforcing cage 1. Therefore, when pouring concrete, the mortar contacts the main reinforcing bar 11 through the notch 32, thereby increasing the fit between the steel hoop 3 and the main reinforcing bar 11.

[0037] As a further embodiment of this utility model, a U-shaped steel bar 7 is inserted into the channel steel member 4, and the U-shaped steel bar 7 extends to the steel cage 1.

[0038] Specifically, during construction, the U-shaped steel bar 7 is fixed to the channel steel part 4 by welding. During the welding process, it is essential to ensure that the U-shaped steel bar 7 is inside the U-shaped steel bar of the steel cage 1. The purpose is to increase the fit between the channel steel part 4 and the steel cage 1 after pouring.

[0039] It should be noted that the height of the reinforcing cage 1 in the embodiment is less than the height of the steel plate 6, and the height referred to is... Figure 1 The vertical direction is shown.

[0040] As another embodiment of the present invention, the steel hoop 3 includes a connecting part 33 connected to the slot part 31, and the insertion interface 34 is located on the connecting part 33.

[0041] Specifically, the connecting part 33 is used to ensure that the distance between the channel steel part 4 and the steel plate 6 is 4cm-5cm, thereby facilitating the pouring of concrete during the casting process.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
