Description

Technical Field

[0001] The present invention belongs to the field of building structures, and particularly relates to an embedded folded - plate lattice core tube. Background Art

[0002] In the early days, tower - barrel structures such as water towers were mostly constructed with masonry or reinforced concrete materials. The tower - barrel of masonry structure, relying on the piling of masonry materials, has a certain compressive capacity. However, it has a large self - weight and poor seismic performance. When facing natural disasters such as earthquakes, it is extremely prone to serious damages such as cracking and collapse, posing a huge threat to the surrounding environment and personnel safety. The reinforced - concrete tower - barrel has improved the structural performance to a certain extent. The combination of the good compressive characteristics of concrete and the tensile strength advantage of steel bars enables the tower - barrel to have better load - bearing capacity. However, with the development of society and the diversification of engineering requirements, traditional reinforced - concrete tower - barrels also expose many drawbacks. On the one hand, the pouring construction process of concrete is complex, requiring a large amount of manpower, material resources and time costs. Processes such as on - site formwork support, steel - bar binding, pouring and vibration, and long - term curing not only have a long construction period, but are also greatly affected by environmental factors such as weather.

[0003] In the field of high - rise core - tube structures, although reinforced - concrete and composite structures are widely used, their disadvantages are significant. The self - weight of the concrete core - tube is large. In super - high - rises, its huge weight increases the burden on the foundation, has extremely high requirements for the foundation, and increases the difficulty and cost of foundation construction. Moreover, the tensile strength of concrete is low. When facing complex external forces such as earthquakes and strong winds, it is easy to crack, affecting the structural safety and durability. During the construction of composite structures, the coordinated work of different materials requires complex joint designs and construction techniques, increasing the construction difficulty and cycle, and is also prone to reducing the overall performance of the structure due to improper joint treatment. In addition, concrete is not recyclable, generating a large amount of construction waste after being discarded, and having poor environmental protection. Summary of the Invention

[0004] In view of this, the present invention provides an embedded folded - plate lattice core tube to solve the above problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: An embedded folded - plate lattice core tube, comprising: a plurality of structural units; the plurality of structural units are spliced together to form a core tube; the structural unit includes an outer panel, a core panel and an inner panel, the core panel is a corrugated plate, located between the outer panel and the inner panel; both the outer panel and the inner panel are fixedly connected to the core panel, and the space surrounded by the outer panel, the inner panel and the core panel is filled with heat - insulating materials.

[0006] Furthermore, the plurality of structural units are spliced into a square or circular core tube.

[0008] Furthermore, both the outer panel and the inner panel are fixedly connected to the core panel by spot welding or plug welding.

[0009] Furthermore, the corrugated plate structure of the core panel is a trapezoidal corrugated steel plate, a sinusoidal corrugated steel plate, a rectangular corrugated steel plate or a semi-circular corrugated steel plate.

[0010] Furthermore, the corrugation arrangement direction of the core panel is horizontal corrugation, vertical corrugation or 45°-angle diagonal corrugation.

[0011] Furthermore, the number of core panels in the structural unit is multiple, and the multiple core panels are fixedly connected through the connecting member, plug welding or pressure welding.

[0012] Furthermore, the corrugation directions of the multiple core panels are arranged in the same direction or orthogonally.

[0013] Furthermore, the thermal insulation material is lightweight foamed concrete or foamed polyurethane.

[0014] Furthermore, the cavity formed by the outer panel, the inner panel and the core panel can be used for laying pipelines.

[0015] The beneficial effects of the present invention are as follows: The structural units of the present invention can be spliced with each other, which is convenient for standardized production, transportation and on-site assembly, realizing intelligent construction. Both the outer panel and the inner panel are connected to the core panel through connecting members, and the connection performance is stable, which can ensure the common force and coordinated deformation among the three.
