Description

Technical Field

[0001] This utility model belongs to the field of composite wall technology, and in particular relates to a double steel plate concrete composite wall with built-in I-beam connection. Background Technology

[0002] In the construction industry, composite walls are widely used as an important structural component in various buildings. Traditional composite walls employ different combination methods depending on the specific needs. For example, when used for thermal insulation and soundproofing, insulation material is added to one side of the brick wall, or an air gap is created in the middle of the brick wall. When used for earthquake resistance, structural columns and ring beams are added to the wall, or steel-reinforced concrete composite walls are used. However, earthquake-resistant walls also have some drawbacks. Traditional earthquake-resistant composite walls typically consist of brick, concrete, and tie bars, requiring precise control of the installation sequence, position, and connection method of each material during construction, making the construction process cumbersome. Furthermore, in the connection between the brick wall and the concrete structural columns, if the tie bars are not properly installed, cracks can easily appear under stress, affecting the integrity and earthquake resistance of the wall.

[0004] Each of the I-beams has multiple positioning holes at equal intervals. The multiple I-beams are arranged in a cubic shape. Then, a longitudinal I-beam is inserted through the multiple positioning holes at the same vertical position. Multiple bent and twisted steel bars are installed between the multiple I-beams in each layer to fix the cubic shape. The transverse steel plates are welded to the upper ends of the multiple I-beams in each layer for fixation.

[0005] Preferably, the bent and twisted steel bar is X-shaped with four ends, with an upper hook at the upper end and a lower hook at the lower end, the opening of the upper hook facing downward and the opening of the lower hook facing upward.

[0006] Preferably, the multiple positioning holes of the different I-beams are located in the same position.

[0007] Preferably, there are multiple transverse steel plates, and the upper ends of the multiple I-beams in each layer are welded together at equal intervals.

[0008] Preferably, the two sides of the cube shape are each connected to a steel plate by a plurality of screws.

[0009] Preferably, the plurality of longitudinal I-beams and the plurality of I-beams are perpendicular to each other.

[0010] Preferably, the transverse steel plate is a rectangular sheet structure.

[0011] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The X-shaped structure of the bent and twisted steel bars in this invention achieves three-dimensional spatial constraint, thereby improving the shear bearing capacity of the composite wall; the insertion and connection of the positioning holes and the longitudinal I-beams ensures effective transfer of vertical loads; and the modular assembly process improves construction efficiency. It can meet the long-term, stable, and efficient safety protection requirements under complex and high-risk working conditions. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1-9 As shown, a double-steel plate concrete composite wall with built-in I-beam connection according to this utility model includes: multiple I-beams 1, steel plates 2, multiple bent and twisted steel bars 3, transverse steel plates 4 and multiple longitudinal I-beams 6.

[0025] Each of the I-beams 1 has multiple positioning holes 101 at equal intervals. The multiple I-beams 1 are arranged in an array to form a cube shape. Then, a longitudinal I-beam 6 is inserted through the multiple positioning holes 101 at the same vertical position. Multiple bent and twisted steel bars 3 are installed between the multiple I-beams 1 in each layer to fix the cube shape. The transverse steel plates 4 are welded to the upper ends of the multiple I-beams 1 in each layer for fixation.

[0026] Furthermore, the bent and twisted steel bar 3 is X-shaped with four ends, with an upper hook 301 at the upper end and a lower hook 302 at the lower end. The opening of the upper hook 301 faces downward and the opening of the lower hook 302 faces upward.

[0027] Furthermore, the multiple positioning holes 101 opened on the different I-beams 1 are distributed in the same position.

[0028] Furthermore, there are multiple transverse steel plates 4, and multiple transverse steel plates 4 are welded to each other at equal intervals at their upper ends.

[0029] Furthermore, the two sides of the cube shape are respectively connected to a steel plate 2 by multiple screws 5.

[0030] Furthermore, the plurality of longitudinal I-beams 6 and the plurality of I-beams 1 are perpendicular to each other.

[0031] Furthermore, the transverse steel plate 4 is a rectangular sheet structure.

[0032] The aforementioned composite wall structure allows for carbon dioxide gas shielded welding or manual arc welding at the connection points. Afterwards, concrete containing slag and fine powder can be poured into the composite wall structure for fixation. Compared to traditional composite wall structures, this invention offers superior overall stability and seismic performance, meeting various structural protection requirements. It can be used as a seismic wall in high-rise buildings, immersed tunnels, and next-generation nuclear power plants.

[0033] The composite wall includes the following core components:

[0034] I-beam 1: Multiple I-beams 1 are arranged in an array to form a cubic frame. Each I-beam 1 has positioning holes 101 (preferably with a diameter of 10-15mm) at equal intervals. The positions of the positioning holes of all I-beams 1 correspond to each other.

[0035] Steel plate 2: Inserted vertically into the positioning hole 101 in the same vertical direction, forming a grid structure with the I-beam 1.

[0036] The bent and twisted steel bar 3 is an X-shaped four-end structure with an upper hook 301 (opening downward) and a lower hook 302 (opening upward) with opposite directions at the upper and lower ends, which are used to hook the flange of the adjacent I-beam 1.

[0037] Horizontal steel plate 4: rectangular sheet structure (thickness 8-12mm), welded at equal intervals to the upper end face of each layer of I-beam 1.

[0038] Longitudinal I-beam 6: Arranged perpendicularly to I-beam 1, with its bottom inserted into the lower layer of I-beam 1 and its top penetrating through the upper layer of I-beam 1.

[0039] This utility model relates to a composite wall system that tightly integrates steel plates and concrete into a single structure. This integrated design significantly improves the lateral stiffness and seismic performance of the composite wall. Simultaneously, it achieves a synergistic enhancement of impact resistance and tensile strength, resulting in a comprehensive improvement in the overall structural safety.

[0040] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
