Description

Technical Field

[0001] This utility model belongs to the field of building curtain wall construction technology, and specifically relates to a cantilever support structure for sawtooth-shaped exterior curtain walls. Background Technology

[0002] In contemporary architecture, designers use a variety of interwoven, uneven, and textured variations to express the textural characteristics of a building's exterior, creating textured curtain walls. Textured curtain walls incorporate more geometric elements such as folds, diagonal lines, curves, and irregular lines to create a three-dimensional and rhythmic surface, not only expressing different textures but also providing diverse visual effects. To enrich the building's form, some building plans use irregularly connected diagonal lines to form a sawtooth-like plane, resulting in a sawtooth-textured curtain wall. In recent years, sawtooth-shaped exterior curtain walls have become increasingly popular due to their aesthetic appeal and strong sense of layering.

[0003] The sawtooth-shaped exterior curtain wall has a complex shape, and to meet its installation requirements, a cantilevered concrete structure is usually required. However, in the existing cantilevered concrete construction process, traditional internal and external scaffolding support systems are usually used. In areas with high formwork, the amount of scaffolding erected is large, the construction cost is high, and the cantilevered scaffolding support will generate cumulative deformation, which has a significant impact on the stability of the scaffolding and poses a safety hazard. Secondly, the construction precision requirements of the concrete structure are high, and the traditional wooden formwork reinforcement system is difficult to guarantee the forming quality of the concrete structure. Utility Model Content

[0007] The thickened drop slab includes cantilever beams, a steel truss floor deck, inner connecting beams, outer connecting beams, outer side panels, and a concrete structure. The cantilever beams are spaced apart along the length of the thickened drop slab, and their inner ends are fixedly connected to the structural beams. The steel truss floor deck is fixed above the cantilever beams. The inner connecting beams are set on the structural beams along the inner edge of the thickened drop slab and connect the cantilever beams as a whole. The outer connecting beams are set along the outer edge of the thickened drop slab and connect to the cantilever beams. The outer side panels are set vertically along the outer edge of the thickened drop slab, and their bottoms are fixedly connected to the outer connecting beams. The concrete structure is poured into the casting cavity formed by the outer side panels, the steel truss floor deck, and the structural beams, and is integrated with the floor slab.

[0008] Furthermore, the thickness of the thickened drop plate is greater than the thickness of the floor slab, and its top surface is lower than the top surface of the floor slab.

[0009] Furthermore, the thickened drop plate is a regular sawtooth plate, composed of sawtooth units connected together; the outer end of the cantilever beam is set at the farthest point from the floor slab corresponding to the sawtooth unit.

[0010] Furthermore, a connecting bar is provided inside the floor slab, with one end of the connecting bar located inside the floor slab and the other end extending into the thickened drop slab.

[0011] Furthermore, the height of the outer side plate is the same as the thickness of the thickened lower plate.

[0012] Furthermore, the outer side plate is a galvanized steel plate with an L-shaped vertical section, including a horizontal plate and a vertical plate; the horizontal plate is welded to the outer connecting beam; the vertical plate has a protrusion on the side near the concrete structure, and the protrusion is embedded in the concrete structure.

[0013] Furthermore, the structural beam is an H-shaped steel beam; the cantilever beam is a channel steel structure; and both the inner and outer connecting beams are angle steel structures.
