Description

Technical Field

[0001] This utility model relates to the technical field of building engineering, specifically to an earthquake-resistant masonry structure. Background Technology

[0002] Masonry structures are a type of building structure with a long history and widespread use worldwide. They are constructed from bricks, stones, blocks, and other block materials and mortar. For a long time in the past, due to their advantages such as easy access to materials, simple construction, and low cost, they were widely used in various types of buildings such as residences, schools, and office buildings. However, masonry structures exhibit relatively obvious fragility under earthquake action.

[0003] Existing masonry structures, due to the high compressive strength but low tensile strength of masonry, are prone to cracking under seismic forces. These cracks include diagonal, horizontal, and vertical cracks. Diagonal cracks are typically caused by the horizontal shear force generated by an earthquake exceeding the wall's shear strength. Horizontal cracks may result from uneven foundation settlement or temperature changes combined with seismic forces. Vertical cracks may be caused by uneven distribution of vertical compressive stress in the wall or poor vertical connections in the masonry. Severe cracking weakens the wall's load-bearing capacity and integrity, leading to instability and collapse. Therefore, a seismic-resistant masonry structure is needed. Utility Model Content

[0004] The purpose of this invention is to provide an earthquake-resistant masonry structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an earthquake-resistant masonry structure, comprising a cast-in-place body, wherein a right structural column is provided inside the cast-in-place body, a structural beam is fixedly connected to the upper end of the right structural column, a left structural column is fixedly connected to the lower end of the structural beam, a protective mechanism is fixedly connected to the front side of the cast-in-place body, masonry is fixedly connected to the rear side of the protective mechanism, a toothed joint is provided on the right side of the masonry, a reinforcing layer is provided at the upper end of the toothed joint, and a tie bar is provided at the upper end of the reinforcing layer;

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This seismic-resistant masonry structure, through the installation of tie bars between the right and left structural columns and the masonry, effectively connects the masonry and structural columns together, making the wall a unified whole in the horizontal direction. The wall is less prone to misalignment, cracking, or collapse, thus improving the stability and shear resistance of the wall. Under seismic loading, the structure mainly bears horizontal shear force, and the tie bars can effectively transfer the horizontal shear force, allowing the masonry and structural columns to share the shear force, better resisting the horizontal force caused by the earthquake and reducing shear failure of the wall. Through the tie bars and the steel mesh reinforcement layer laid on the masonry surface, stress can be better transferred and dispersed, making the effect of the tie bars more uniform and effective, thereby improving the overall integrity and seismic resistance of the entire structure.

[0015] 2. This seismic-resistant masonry structure, by setting a carbon fiber reinforcement layer 1 and a steel mesh reinforcement layer 2 on the surface of the masonry and the cast-in-place body, and protecting it with a high-ductility concrete reinforcement protective layer 1 and a high-ductility concrete reinforcement protective layer 2, can significantly improve the integrity of the masonry and increase its tensile and shear strength. It can effectively restrain the development of cracks in the masonry, improve the load-bearing capacity of the masonry, and make the structure more stable under stress. Furthermore, the high-ductility concrete can further enhance the strength and stiffness of the structure, providing better seismic performance and impact resistance. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This utility model provides a technical solution: an earthquake-resistant masonry structure, including a cast-in-place body 1, with a right structural column 2 inside the cast-in-place body 1. A structural beam 3 is fixedly connected to the upper end of the right structural column 2, and a left structural column 4 is fixedly connected to the lower end of the structural beam 3. A protective mechanism 5 is fixedly connected to the front side of the cast-in-place body 1, and masonry 6 is fixedly connected to the rear side of the protective mechanism 5. A toothed joint 7 is provided on the right side of the masonry 6, with a reinforcing layer 8 at the upper end of the toothed joint 7, and tie bars 9 at the upper end of the reinforcing layer 8. The reinforcing steel mesh layer 8 laid on the surface of the reinforcing bars 9 and masonry 6 can better transfer and disperse stress, making the effect of the tie bars 9 more uniform and effective, thereby improving the overall integrity and seismic resistance of the entire structure. The protective mechanism 5 includes a first reinforcement layer 501, a first reinforcement protective layer 502, a second reinforcement layer 503, and a second reinforcement protective layer 504. The first reinforcement layer 501 is located on the front side of the masonry 6, and the first reinforcement protective layer 502 is set on the front side of the first reinforcement layer 501. The first reinforcement protective layer 504 is set on the front side of the first reinforcement protective layer 502. A second reinforcing layer 503 is formed, and a second reinforcing protective layer 504 is provided on the front side of the second reinforcing layer 503. The structural beam 3 is located at the upper end of the right structural column 2 and the left structural column 4. Masonry 6 is located between the right structural column 2 and the left structural column 4. Three toothed joints 7 are provided on both the left and right sides of masonry 6. Masonry 6 is laid using a "one header, one stretcher" method. Tie bars 9 are fixedly connected between the right structural column 2 and the left structural column 4. Six tie bars 9 are provided between the right structural column 2 and the left structural column 4. The tie bars 9 between column 4 and masonry 6 effectively connect masonry 6 and structural column, making the wall a whole in the horizontal direction. The wall is less prone to misalignment, cracking or collapse, which improves the stability of the wall and its shear resistance. Under earthquake action, the structure mainly bears horizontal shear force. The tie bars 9 can effectively transfer the horizontal shear force, so that masonry 6 and structural column share the shear force, which can better resist the horizontal force caused by earthquake and reduce shear failure of the wall.

[0025] Please see Figure 2-6In this embodiment, protective mechanisms 5 are provided on both the front and rear sides of the masonry 6. The cast-in-place body 1 is cast on the outside of the right structural column 2, structural beam 3, and left structural column 4. The first reinforcement layer 501 is made of carbon fiber cloth, the second reinforcement layer 503 and the reinforcing layer 8 are both made of steel mesh, and the first reinforcement protective layer 502 and the second reinforcement protective layer 504 are both made of high-ductility concrete. The first reinforcement protective layer 502 is located between the first reinforcement layer 501 and the second reinforcement layer 503. The protective mechanism 5 is formed by setting carbon fiber cloth on the surface of the masonry 6 and the cast-in-place body 1. The fiber cloth reinforcement layer 501 and the steel mesh reinforcement layer 503, along with the high-ductility concrete reinforcement protective layer 502 and reinforcement protective layer 504, can significantly improve the integrity of the masonry 6 and increase its tensile and shear strength. This can effectively restrain the development of cracks in the masonry 6, improve its load-bearing capacity, and make the structure more stable under stress. Furthermore, the high-ductility concrete can further enhance the strength and stiffness of the structure, providing better seismic performance and impact resistance.

[0026] Working principle: By setting the tie bars 9 between the right structural column 2, the left structural column 4, and the masonry 6, the masonry 6 and the structural columns can be effectively connected together, making the wall a whole in the horizontal direction. The wall is less prone to misalignment, cracking, or collapse, thus improving the stability and shear resistance of the wall. Under earthquake action, the structure mainly bears horizontal shear force. The tie bars 9 can effectively transfer the horizontal shear force, allowing the masonry 6 and the structural columns to share the shear force, which can better resist the horizontal force caused by the earthquake and reduce shear failure of the wall. Through the tie bars 9 and the steel mesh reinforcement layer 8 laid on the surface of the masonry 6, stress can be better transferred and dispersed. To make the effect of the tie bars 9 more uniform and effective, thereby improving the overall integrity and seismic resistance of the entire structure, carbon fiber cloth reinforcement layer 501 and steel mesh reinforcement layer 503 are set on the surface of the masonry 6 and the cast-in-place body 1, and protected by high-ductility concrete reinforcement protective layer 502 and reinforcement protective layer 504. This can significantly improve the integrity of the masonry 6 and increase its tensile and shear strength, effectively restrain the crack propagation of the masonry 6, improve the load-bearing capacity of the masonry 6, make the structure more stable under stress, and further enhance the strength and stiffness of the structure under the action of high-ductility concrete, providing the structure with better seismic performance and impact resistance.
