Description

Technical Field

[0001] This utility model relates to the field of shear wall technology, and in particular to a basement anti-cracking shear wall. Background Technology

[0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls, or structural walls, are walls in buildings or structures that primarily bear horizontal and vertical loads caused by wind loads or earthquakes to prevent structural shear failure. They are also called earthquake-resistant walls and are generally made of reinforced concrete. Shear walls are usually prefabricated in a factory and reinforced with steel bars to improve their earthquake resistance.

[0003] Currently, when traditional shear walls are subjected to vibration, although they are reinforced with steel bars inside for earthquake resistance, the rigidity of the steel structure reduces the effectiveness of earthquake resistance. Over time, the shear walls may crack due to vibration, thus reducing their stability. Utility Model Content

[0004] The purpose of this utility model is to provide a crack-resistant shear wall for basements to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a basement anti-cracking shear wall, including a shear wall, wherein the interior of the shear wall is filled with multiple hollow square steel bars, and the hollow square steel bars are made of the same material as threaded steel bars, and each hollow square steel bar forms a sheet-like mesh structure.

[0006] Preferably, the shear wall is made of cast concrete.

[0007] Preferably, the interior of the hollow square steel bar is divided into multiple cavities, and each cavity is relatively independent. Each cavity is filled with steel balls and sand.

[0008] Preferably, the shear wall has multiple honeycomb panels embedded inside.

[0009] Preferably, the honeycomb panel is made of spring steel.

[0010] Preferably, the honeycomb panels are erected with the front side facing forward, and the remaining honeycomb panels are evenly distributed in the longitudinal and transverse directions, so that the shear wall has a cross structure on both sides and the top and bottom surfaces.

[0011] This utility model provides an improved basement crack-resistant shear wall, which has the following improvements and advantages compared with the prior art:

[0012] Firstly, this utility model uses hollow square steel bars of the same material as threaded steel bars, and each hollow square steel bar forms a sheet-like mesh structure, which increases the contact area with concrete and at the same time increases the longitudinal and transverse bending resistance of concrete.

[0013] Secondly, the hollow square steel bar of this utility model is divided into multiple sections, and each section is filled with sand and steel balls. When the concrete shear wall vibrates, the steel balls vibrate accordingly, dispersing the force. The sand can also buffer the steel balls, so the hollow square steel bar can perform self-buffering and reduce the vibration amplitude.

[0014] Third, when the hollow square steel bar vibrates to one side, the steel column also moves to one side due to inertia. When the hollow square steel bar rebounds, the steel ball continues to move and collides with the hollow square steel bar, thereby canceling out the force and further reducing the vibration amplitude.

[0015] Fourth, this utility model uses honeycomb steel plates made of spring steel. Multiple honeycomb steel plates are set in both the horizontal and vertical directions, and both sides and the top and bottom have cross structures, which increases the torsional resistance of the four sides of the shear wall. At the same time, since the honeycomb steel plates are made of spring steel, the shear wall has good buffering capacity. Attached Figure Description

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved crack-resistant shear wall for basements. The technical solution of this utility model is as follows:

[0025] like Figures 1 to 4 As shown, this utility model embodiment provides a basement anti-cracking shear wall 1, including a shear wall 1, the interior of which is filled with multiple hollow square steel bars 2, and the hollow square steel bars 2 are made of the same material as threaded steel bars, and each hollow square steel bar forms a sheet-like mesh structure;

[0026] As can be seen from the above description, this utility model uses hollow square steel bars 2 with the same material as threaded steel bars, and each hollow square steel bar forms a sheet-like mesh structure, which increases the contact area with concrete and increases the longitudinal and transverse bending resistance of concrete.

[0027] Specifically, shear wall 1 is made of cast concrete; to improve waterproofing, waterproof material is filled inside the concrete.

[0028] Specifically, the interior of the hollow square steel bar 2 is divided into multiple cavities, and each cavity is relatively independent. Each cavity is filled with steel balls 5 and sand 4.

[0029] As described above, the hollow square steel bar 2 is divided into multiple sections, each filled with sand 4 and steel balls 5. When the concrete shear wall 1 vibrates, the steel balls 5 vibrate accordingly, dispersing the force. The sand 4 also cushions the steel balls 5, thus enabling the hollow square steel bar 2 to self-buffer and reduce the vibration amplitude. When the hollow square steel bar 2 vibrates to one side, the steel column moves to the same side due to inertia. When the hollow square steel bar 2 rebounds, the steel balls 5 continue to move and collide with the hollow square steel bar, thus canceling out the force and further reducing the vibration amplitude.

[0030] Specifically, multiple honeycomb panels 3 are embedded inside the shear wall 1; the honeycomb holes in the honeycomb panels 3 have good mechanical properties, and their mechanical structure will not be analyzed here.

[0031] Specifically, the honeycomb panel 3 is made of spring steel. Because the honeycomb steel panel is made of spring steel, the shear wall 1 has good buffering capacity.

[0032] Specifically, the honeycomb panel 3 is erected with its surface facing forward, and the remaining honeycomb panels 3 are evenly distributed in the longitudinal and transverse directions. This gives the shear wall 1 a cross structure on both sides and the top and bottom surfaces, thus increasing the torsional resistance of the four sides of the large shear wall 1.

[0033] Working principle: The hollow square steel rods form a sheet-like mesh structure, increasing the contact area with the concrete and simultaneously increasing the longitudinal and transverse bending resistance of the concrete. When the concrete shear wall 1 vibrates, the steel balls 5 vibrate accordingly, dispersing the force. The sand 4 further cushions the steel balls 5, allowing the hollow square steel rods 2 to self-buffer and reduce the vibration amplitude. When the hollow square steel rods 2 vibrate to one side, the steel column moves to the same side due to inertia. When the hollow square steel rods 2 rebound, the steel balls 5 continue to move and collide with the hollow square steel rods, thus canceling out the force and further reducing the vibration amplitude. Multiple honeycomb steel plates are installed in both the transverse and longitudinal directions, and have a cross structure on both sides and the top and bottom surfaces, increasing the torsional resistance of the four sides of the shear wall 1. At the same time, because the honeycomb steel plates are made of spring steel, the shear wall 1 has good buffering capacity.

[0034] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
