Problems solved by technology

[0004] 1. The overall rigidity of prefabricated shear walls and special-shaped columns is worse than that of cast-in-place structures
Especially at the joints where the upper and lower members are spliced, the stiffness is prone to sudden changes, resulting in shear slip damage that is prone to occur at the site of sudden changes in the stiffness of the shear wall
[0005] 2. In the case of relatively large axial compression of shear wall components, buckling damage may occur to prefabricated shear wall components. At this time, the compressed steel bars are buckled and the concrete is crushed, eventually leading to structural damage
[0006] 3. When the prefabricated shear wall is relatively low, under the action of horizontal force, oblique diagonal cracks or cross oblique cracks appear on the wall, causing the concrete to be crushed and peeled off in pieces, and the stirrups bulge or break , the final member undergoes shear baroclinic failure

Embodiment 1

[0050] Such as figure 1 , 3, 5, and 7, the present embodiment discloses a corrugated steel plate 1, a concrete 12, a steel strip 2 and a horizontal butt joint steel plate 3; The surface welded steel strips 2 form a ten-shaped steel skeleton, and the corrugated steel plate 1 has an isosceles trapezoidal waveform;

[0051] Concrete 12 is poured on the ten-shaped steel skeleton to form the assembled built-in corrugated steel plate reinforced concrete ten-shaped section member; it can better ensure the integrity of the steel skeleton, better restrain the concrete, and increase the gap between the corrugated steel plate and the concrete. Mechanical interlocking force, thereby improving the bearing capacity of components.

[0052] In the intersecting area where the ten-shaped steel skeleton is perpendicular to the two directions of the ten-shaped cross-section, the steel strips 2 are arranged in a staggered manner, and the longitudinal steel bars 6 are arranged at the staggered po...

Embodiment 2

[0067] Such as figure 2 , 4 , 6, and 7, this embodiment discloses a prefabricated built-in corrugated steel plate reinforced concrete ten-shaped column member, which is different from embodiment 1 in that the assembled built-in corrugated steel plate reinforced concrete ten-shaped column member in this embodiment The length of the column body is 1043mm, the column thickness is 300mm, the ratio of the length h of the column body to the column thickness b is less than or equal to 4, and the thickness of the corrugated steel plate 1 arranged in it is 4-6mm, and the waveform is isosceles trapezoidal. The gradation of the concrete poured by the ten-shaped column member is grade two, and the maximum particle size of the coarse aggregate shall not exceed 25mm. In order to ensure that the concrete can be vibrated and compacted smoothly, the wave length 10 of the corrugated steel plate arranged in the ten-shaped column member is 40-60 mm, and the maximum bending angle 9 is 30 degrees...

Abstract

The invention discloses an assembly type built-in corrugated steel plate reinforced concrete cross-shaped section component and a construction process. The assembly type built-in corrugated steel plate reinforced concrete cross-shaped section component comprises corrugated steel plates, concrete, steel lacing bars and horizontal butt joint steel plates; the four corrugated steel plates are vertically spliced together, the steel lacing bars are welded to the side surfaces of the corrugated steel plates to form a cross-shaped steel framework, and the corrugations of the corrugated steel plates are isosceles trapezoids; and the concrete is poured on the cross-shaped steel framework to form the assembly type built-in corrugated steel plate reinforced concrete cross-shaped section component. The corrugated steel plates are used for replacing vertical distribution ribs of a traditional shear wall and longitudinal ribs in special-shaped columns to form regional confined concrete, the confinedstrength of the concrete can be effectively improved, and therefore the vertical load bearing capacity of the component is greatly improved.

Description

technical field [0001] The invention relates to the field of building assembly structure design, in particular to an assembly type built-in corrugated steel plate reinforced concrete ten-shaped section member and a construction process. Background technique [0002] Nowadays, with the rapid development of construction industrialization represented by prefabricated buildings in my country, prefabricated shear wall structures are more and more widely used in residential buildings. The prefabricated shear wall structure is mainly used in high-rise, small high-rise residential buildings and other buildings. It has the advantages of high degree of industrialization, controllable cost, and faster construction speed than cast-in-place shear wall. However, the current prefabricated shear walls still have many deficiencies in construction, such as: more complex connections, more work at nodes, low construction efficiency, poor construction accuracy, and high technical requirements fo...
