Abstract
The invention relates to a double-layer steel plate combined shear wall formed by drawing and connecting a corrugated web plate and an I-shaped steel member, belonging to the field of structural engineering. The combined shear wall is composed of a double-layer steel plate shear wall formed by welding a plurality of steel plate shear wall units with corrugated web I-shaped steel members and integrally poured concrete. The steel plate shear wall unit is formed by welding two outer steel plates which are symmetrical front and back and a corrugated web plate I-shaped steel member which is as long as the outer steel plates. The web width of the I-shaped steel member of the corrugated web can be obviously larger than the horizontal distance of the I-shaped steel member of the corrugated web, so that the elastic buckling load of the plates among the cells is close, and the economy of the steel plate shear wall is effectively improved. The corrugated web plate in the I-shaped steel member of the corrugated web plate only bears the lateral force and does not bear the vertical force basically in the stress process of the wall body, and compared with a flat web plate, the corrugated web plate is not unstable under compression, so that the connection performance of the I-shaped steel member of the corrugated web plate and an outer steel plate is effectively ensured, and the overall stability is obviously improved.

Technical Field
The patent relates to a double-deck steel sheet composite wall of corrugated web I shaped steel drawknot belongs to the structural engineering field.
Background
Along with the continuous development and progress of economic level, scientific level and building level, the building structure in China also presents a more and more complex development trend, the building height is increased day by day, and high-rise and super high-rise buildings are common in all big cities. Along with the increasing height of buildings, horizontal load gradually replaces vertical load to become an important control factor in the design of high-rise buildings, and the traditional lateral force resisting member cannot meet the requirements of the high-rise buildings on energy consumption capacity and horizontal bearing capacity.
The steel plate composite wall structure is a novel lateral force resistant structure system developed in the last 70 th century, and becomes a structure favored by many designers due to the extremely high bearing capacity, the stable energy consumption capacity and the good ductility. Over the past 40 years, experimental studies and numerical analysis on steel plate walls as the main horizontal lateral force resisting system revealed its unique performance, including large elastic initial stiffness, large deformability and good plasticity properties, stable hysteresis characteristics, etc. The steel plate wall becomes a high-rise lateral force resisting system with great development prospect, and is particularly suitable for buildings in high-intensity earthquake areas.
The double-layer steel plate and concrete filled combined wall is one of steel plate-concrete combined walls. In the combined wall, concrete is positioned at a core position and is restrained by two steel plates; meanwhile, the core concrete can also play a role in preventing the steel plate from buckling too early. From the aspect of stress performance, the combined mode can exert the advantages of two materials, has very high compression bearing capacity and shear bearing capacity, and is particularly suitable for high-rise and super high-rise buildings.
On the basis, in order to overcome the defect that the double-layer steel plate composite wall is prone to out-of-plane buckling, further enhance the bearing capacity and the energy consumption capacity of the double-layer steel plate composite wall, improve the buckling mechanism of the double-layer steel plate composite wall and achieve the assembly of steel structure residential construction, the invention provides the corrugated web plate I-shaped steel drawknot double-layer steel plate composite wall.
The double-layer steel plate combined wall structure applies the corrugated web I-shaped steel to the wall structure, and the two outer steel plates which are symmetrical front and back are tightly connected together through the corrugated web I-shaped steel, so that the overall rigidity of the structure is enhanced, and the shearing resistance and the pressure resistance of the wall are improved. The use of the combined wall unit enables the installation and use of the whole wall to develop towards the direction of an assembly type, the arrangement mode is more flexible, the construction is convenient and fast, and the quality is easy to guarantee.
Disclosure of Invention
The invention provides a steel plate composite wall with a corrugated web plate and I-shaped steel, and belongs to the field of structural engineering. Two steel plates on the outer side and the middle I-shaped steel with the corrugated web are welded to form a steel plate shear wall unit; forming a pure steel plate wall by welding the steel plate shear wall units; and finally, pouring concrete among the steel plates to form the steel plate composite wall with the corrugated web plate I-shaped steel.
In order to achieve the purpose, the invention adopts the following technical means:
the combined wall is composed of a double-layer steel plate shear wall formed by welding a plurality of steel plate shear wall units with corrugated web I-shaped steel and integrally poured concrete. The steel plate shear wall unit comprises two outer steel plates which are symmetrical front and back and a corrugated web I-shaped steel which has the same length with the outer steel plates; the I-shaped steel flanges of the corrugated web plates in the steel plate shear wall units are respectively welded with the two outer steel plates to tie the two outer steel plates; the steel plate shear wall units form a double-layer steel plate shear wall by welding outer steel plates; the direction of a welding seam between the steel plate shear wall units is along the length direction of the outer steel plate; and after the double-layer steel plate shear wall is welded and formed, pouring concrete to form the corrugated web plate I-shaped steel drawknot double-layer steel plate combined wall.
The corrugated web I-shaped steel is welded on an outer steel plate in the steel plate shear wall unit in the middle, and the central axis of the corrugated web I-shaped steel is enabled to coincide with the central axis of the outer steel plate.
The advantages of the patent are mainly shown in the following aspects:
1. the corrugated web plate I-shaped steel is connected with the two outer steel plates, the integrity of the wall body is improved, the bending resistance bearing capacity of the corrugated web plate I-shaped steel perpendicular to the flange direction is high, the integral side resistance of the wall can be improved when the corrugated web plate I-shaped steel is applied to the wall body structure, the corrugated web plate I-shaped steel is arranged in the full length direction of the wall height, and the bearing capacity and the bending resistance bearing capacity of the wall body are improved.
2. The inner filling concrete provides transverse support for the peripheral steel plate, instability of the steel plate towards the inner side is avoided, and meanwhile the peripheral steel plate provides lateral restraint for the inner filling concrete, so that the inner filling concrete is in a bidirectional compression state, the compression resistance of the concrete is improved, and development of concrete cracks is slowed down.
3. The double-layer steel plate can be used as a concrete template, so that a formwork supporting procedure is omitted, the construction period is shortened, and the concrete is restrained by the steel plate and cannot fall down even being crushed.
4. The arrangement mode is more flexible, and because the area of wall body is great, the steel sheet size is great for traditional steel sheet wall, and there are a lot of inconveniences no matter transport or installation. The form of using the combination wall unit splices into whole wall body at the scene in this patent, can satisfy the requirement of different sizes and form.
5. This patent has very big partly work to accomplish in the factory in the work progress, very big shortening construction period, the error that probably appears in the effectual field construction of having avoided has still alleviateed the environmental pollution of job site simultaneously.
