Abstract
Description
Technical Field
[0001] The present application relates to the technical field of building structures, and in particular to a reinforced concrete composite shear wall structure. Background Art
[0002] Shear wall, also known as wind-resistant wall, earthquake-resistant wall or structural wall, is a wall in a house or structure that mainly bears horizontal loads and vertical loads (gravity) caused by wind loads or earthquakes to prevent structural shear (shear) damage. It is also called earthquake-resistant wall and is generally made of reinforced concrete.
[0003] Reinforced concrete composite shear wall structure is a commonly used structural form that can effectively bear the horizontal load of the building and improve the overall seismic performance.
[0004] However, due to the insufficient performance of the bearing capacity and stiffness of the shear wall in the existing technology, the seismic load will have a certain impact on the shear wall structure to a greater or lesser extent.
[0005] To this end, this application proposes a reinforced concrete composite shear wall structure. Utility Model Content
[0006] The present application proposes a reinforced concrete composite shear wall structure to solve the problems raised in the above-mentioned background technology; the shear wall structure is divided into a left area, a right area and a middle area. By arranging H-shaped steel in the middle area, the H-shaped steel is longer than the I-steel wing plate and can withstand forces in two directions, one force from top to bottom and the other force from left to right, so the bearing capacity is stronger. By arranging multiple steel plates in the left area and the right area, the force on the wall can be dispersed, the impact of seismic loads on the structure can be reduced, the overall stability can be improved, and the practicality of the device can be greatly improved.
[0007] In order to achieve the above objectives, this application adopts the following technical solutions:
[0008] A reinforced concrete composite shear wall structure includes a first formwork, a second formwork, side panels and H-shaped steel. Two side panels are fixedly connected on both sides of the first formwork and the second formwork. A left area is provided between the first formwork and the second formwork and located on one side of one of the side panels. A right area is provided between the first formwork and the second formwork and located on one side of the other side panel. An intermediate area is provided between the left area and the right area, and an H-shaped steel is provided inside the intermediate area.
[0009] As a preferred embodiment, three groups of carrying steel bars are respectively provided between the first template and the second template and in the left area and the right area, and each group of carrying steel bars is provided with load-bearing steel bars;
[0010] By setting up load-bearing steel bars, the main function of the load-bearing steel bars is to bear tensile and compressive stresses so that the bearing capacity of the components meets the structural function requirements. The load-bearing steel bars are also called stress bars. They are the main steel bars configured in concrete structures and are used to bear tensile stress or compressive stress caused by loads, thereby improving the practicality of the device.
[0011] As a preferred embodiment, a steel plate is provided on the outside of each of the bearing steel bars, and the total number of the steel plates is six, three of which are provided in the left area and three in the right area;
[0012] By arranging a plurality of steel plates in the left area and the right area, the force on the wall can be dispersed, and the overall stability can be improved, thereby enhancing the practicality of the device.
[0013] As a preferred embodiment, concrete is poured between the first formwork and the second formwork, and the concrete is divided into a first layer of concrete, a second layer of concrete and a third layer of concrete, and the first layer of concrete is poured on the bottom layer between the first formwork and the second formwork;
[0014] By pouring concrete in layers, the generation of bubbles and voids is avoided, the integrity and bearing capacity of the structure are improved, thereby enhancing the practicality of the device.
[0015] As a preferred embodiment, the second layer of concrete is poured in the middle layer between the first formwork and the second formwork, and the second layer of concrete is located on the first layer of concrete;
[0016] By pouring concrete in layers, deformation or expansion of the first formwork and the second formwork is avoided, thereby improving the practicality of the device.
[0017] As a preferred embodiment, the third layer of concrete is poured on the top layer between the first formwork and the second formwork, and the third layer of concrete is located on the second layer of concrete;
[0018] By pouring in layers, the vibration quality of concrete can be better controlled to ensure that each layer of concrete is fully compacted, thereby improving the practicality of the device.
[0019] Beneficial effects of this application:
[0020] 1. This reinforced concrete composite shear wall structure is divided into a left area, a right area, and a middle area. By installing H-shaped steel in the middle area, the H-shaped steel is longer than the I-beam flange and can withstand forces in two directions: one from top to bottom and the other from left to right. Therefore, the load-bearing capacity is stronger. By installing multiple steel plates in the left and right areas, the force on the wall can be dispersed, reducing the impact of seismic loads on the structure, improving the overall stability, and greatly enhancing the practicality of the device.
[0021] 2. In this reinforced concrete composite shear wall structure, when pouring concrete, if the concrete is poured full at once, the first and second formworks may be deformed or expanded due to the concrete's own weight and pouring pressure, thereby causing cracks in the concrete. By pouring in layers, the vibration quality of the concrete can be better controlled, ensuring that each layer of concrete is fully dense, avoiding the generation of bubbles and voids, improving the integrity and bearing capacity of the structure, and greatly enhancing the practicality of the device.

Two side plates 3 are fixedly connected on both sides of the first formwork 1 and the second formwork 2. A left area 4 is provided between the first formwork 1 and the second formwork 2 and on one side of one of the side plates 3.

The load-bearing steel bars 8 are also called stress bars, which are the main steel bars configured in the concrete 11 structure and are used to bear tensile stress or compressive stress caused by the load, thereby improving the practicality of the device.
[0029] A steel plate 9 is provided on the outside of each load-bearing steel bar 8, and the total number of steel plates 9 is six, three of which are provided in the left area 4 and three in the right area 5; by arranging multiple steel plates 9 in the left area 4 and the right area 5, the force on the wall can be dispersed, the overall stability can be improved, and the practicality of the device can be enhanced.
[0030] Concrete 11 is poured between the first formwork 1 and the second formwork 2. The concrete 11 is divided into a first layer of concrete 111, a second layer of concrete 112 and a third layer of concrete 113. The first layer of concrete 111 is poured on the bottom layer between the first formwork 1 and the second formwork 2. By pouring the concrete 11 in layers, the generation of bubbles and voids is avoided, the integrity and bearing capacity of the structure are improved, and the practicality of the device is improved.
[0031] The second layer of concrete 112 is poured in the middle layer between the first formwork 1 and the second formwork 2, and the second layer of concrete 112 is located on the first layer of concrete 111; by pouring concrete in layers, deformation or expansion of the first formwork 1 and the second formwork 2 is avoided, thereby improving the practicality of the device.
[0032] The third layer of concrete 113 is poured on the top layer between the first formwork 1 and the second formwork 2, and the third layer of concrete 113 is located on the second layer of concrete 112; by layered pouring, the vibration quality of the concrete 11 can be better controlled to ensure that each layer of concrete 11 is fully dense, thereby improving the practicality of the device.
[0033] Working principle: The shear wall structure is divided into a left area 4, a right area 5 and a middle area 6. By arranging an H-shaped steel 10 in the middle area 6, the H-shaped steel 10 is longer than the I-beam flange and can withstand forces in two directions, one from top to bottom and the other from left to right, so it has stronger bearing capacity.
[0034] By arranging a plurality of steel plates 9 in the left area 4 and the right area 5, the stress on the wall can be dispersed and the overall stability can be improved.
[0035] When pouring concrete 11, if the concrete 11 is poured all at once, the first formwork 1 and the second formwork 2 may be deformed or expanded due to the self-weight of the concrete 11 and the pouring pressure, thereby causing cracks in the concrete 11. By pouring in layers, the vibration quality of the concrete 11 can be better controlled, ensuring that each layer of concrete 11 is fully dense, avoiding the generation of bubbles and voids, and improving the integrity and bearing capacity of the structure.
