Description

Integral assembled reinforced concrete shear wall structure system

technical field

The utility model relates to the technical field of integrally assembled building structures, in particular to an integrally assembled reinforced concrete shear wall structure system.

Background technique

With the development of modern industrial technology, building houses can be manufactured in batches and in sets like machine production. Just transport the prefabricated building components to the construction site and assemble them.

Assembled architecture began to arouse people's interest in the beginning of the 20th century, and finally realized to the sixties. Britain, France, the Soviet Union and other countries first made attempts. Because the construction speed of prefabricated building is fast, and production cost is relatively low, it is promoted all over the world rapidly.

The shear wall structure uses reinforced concrete wall panels to replace the beams and columns in the frame structure, which can bear the internal forces caused by various loads and can effectively control the horizontal force of the structure. The structure of the force is called the shear wall structure. This structure is widely used in high-rise buildings.

The shear wall structure refers to the structure in which all the main load-bearing structures in the vertical and horizontal directions are structural walls. When the walls are properly positioned in the building, they form a structural system that effectively resists horizontal action and, at the same time, acts as a partition of space. The height of the structural wall is generally equal to the height of the entire house, from the foundation to the roof, as high as tens of meters or more than 100 meters; its width depends on the layout of the building plan, generally ranging from a few meters to more than ten meters. Relatively speaking, its thickness is very thin, generally only 200~300mm, and the minimum can reach 160mm. Therefore, the anti-sway stiffness of the structural wall in the plane of the wall is very large, but the stiffness outside the plane of the wall is very small, which can generally be ignored. Therefore, most of the horizontal acting or horizontal shear forces on a building are usually distributed to the structural walls.

The shear wall structure refers to the vertical reinforced concrete wall panels, and the horizontal direction is still a large reinforced concrete slab mounted on the wall. This constitutes a system called a shear wall structure. The higher the floor, the greater the wind load pushes it, then the wind push is called horizontal push, such as a house, the bottom is restricted, and the wind above should produce a certain swing float, the swing float limit It is very small, relying on the vertical wall panels to resist, when the wind blows, the panels have a force against the top, so that the building does not sway or the amplitude of swaying is very small, within the range allowed by the structure, for example: When the wind comes from one side, then the board has a considerable force against it, which is equivalent to a pair of forces along the height of the entire vertical wall board, just like a kind of shearing, which is equivalent to cutting the building with scissors and cutting the building. The more downward the shear force is, the greater the shear force is, therefore, such a wallboard is called a shear wallboard.

The current shear wall system is basically realized by concrete cast-in-place, and the integral assembly structure is rarely used. However, the existing integral assembly structure can only realize the standardized assembly of ordinary buildings, and it is difficult to realize the shear wall structure system. Therefore, it is an urgent problem in this field to improve the efficiency of building construction by developing and designing a shear wall structure system that can be assembled as a whole.

In the specific application process, 1) the two-body or three-body joint welding of the outer longitudinal wall panels, outer longitudinal frame panels and inner and outer transverse wall panels and frame panels, the bay modulus of this design is 300mm, and the bays start from 2100mm to 6000mm, 14 types Different shapes and different forms of bay wall panels, and frame panels are one form.

The connection method of the outer longitudinal wall panels and frame panels with the inner and outer transverse wall panels and frame panels. Regardless of the size of the bay, regardless of the upper floor, the lower floor or the middle floor, and regardless of the height of the storey, the vertical and horizontal wall panels and frame panels cooperate with each other to be unified up and down, a connection method. That is, according to the location and structure requirements of doors and windows, four sets of iron parts or four sets of steel bars are pre-embedded at the connection of each horizontal wall panel or horizontal frame panel to prepare for the corresponding steel bars protruding from the vertical wall panel or longitudinal frame panel. Weld each other.

The shelving connection accounts for 65% of the compressive area in low-rise buildings with low seismic requirements, and 45% of the compressive area in middle-rise buildings with high seismic requirements. The upper and lower floors are vertically connected, mainly relying on the reinforced concrete columns inside the wall panels. For low-rise buildings with low seismic requirements, the reinforced concrete columns account for about 35% of the compressive area, and for middle-rise buildings with high seismic requirements. Reinforced concrete columns account for about 55% of the area, and the vertical connection between the upper and lower floors is mainly the connection of reinforced concrete columns. At the position of the reinforced concrete columns on the upper and lower floors, there is a gap in the floor, which is only 10mm pressed against the wall panels, so that the internal reinforcement of the wall panels or frame panels The vertical steel bars in the concrete column are all inserted into the upper wall panel or frame slab reinforced concrete column through the floor slab to connect with the reinforcement of the upper reinforced concrete column (the space part of the upper frame not connected with the floor, the pre-embedded steel bars of the frame beam and the floor are poured on the Integral), the reinforced concrete column area in the upper wall panel and frame plate is concave 120mm, and the steel bars protrude from the bottom of the floor below, so that after the upper wall panel and frame plate are installed and positioned, they will be in the compression area of the reinforced concrete column of the wall panel and frame plate A space with a floor thickness plus 120mm is formed within the scope. In this space, the steel bars in the reinforced concrete of the upper and lower floors are interspersed and welded, and the steel bars protruding from the adjacent floors are interspersed and welded, and then poured with high-strength expanded steel wire concrete to form a whole. The space left is large, and the operation surface is on the upper floor, which is easy to weld steel bars and pour concrete. Using high-strength concrete such as super-C100 grade concrete to pour the joints can enhance the pressure transmitted between the upper and lower floors, and can enhance the overall stability of the building, just like the overall stability of a wooden structure depends on the riveting and tenon structure.

The connection between the upper and lower layers of the inner and outer longitudinal wall panels or frame panels, in the calculation of the whole set of structures, it does not bear the force transmission, it only bears the force transmitted by its own weight from top to bottom, when necessary. When the force generated by its own weight cannot bear it, it can be transferred to the transverse wall. In addition to its use function, the internal and external longitudinal wall panels and frame panels mainly support and tie the building to achieve stability. The vertical and horizontal wall panels and the frame panels are connected up and down mainly by the connecting lines between the vertical and horizontal wall panels and the frame panels. As for the connection between the upper and lower vertical wall panels and frame panels, the upper vertical wall panels or frame panels are directly pressed on the lower vertical wall panels or frames, and the middle is bonded with 10mm mortar. The upper and lower vertical wall panels and frame panels are also connected by steel bars. , and it is also welded, but it is a steel connection configured according to the structural requirements. The vertical structural steel bar of the longitudinal wall panel or frame panel of the lower layer protrudes 120mm from the wall panel or frame panel, and is welded with the corresponding vertical steel bar of the vertical wall panel or frame panel of the upper layer. 100mm wide and 120mm high welding slots are reserved for the upper vertical wall panels or frame panels, and high-grade concrete is poured after the steel bars are welded.

The utility model is based on the current civil building structure theory and design specifications, and according to the span, bay, and floor height modulus generally adopted in the architectural patterns of various countries in the world today, and more than 100,000 component drawings are designed according to the component standardization series. The figure uses thermal insulation filling materials for internal modeling, and the combination of wall panels and frames is used for large spaces. Low, medium, and high-rise buildings have different thicknesses, different shapes, and different configurations of steel bars to correspond to the components. Every part of any civil building has a corresponding component. Try to make the space in each bay consist of four pieces. Combination of components.

Adjacent component structures, construction joints are standardized, and reinforcement joints are standardized. Combining completely in accordance with the current structural codes, the shape of the components selected for each part of the composite building is fixed, and the number of steel bars is fixed, but the concrete grade of the components and the specification and model of the steel bars are determined by structural calculations and seismic calculations.
