Description

Technical Field

[0001] The utility model belongs to the technical field of building beam construction, and specifically relates to a composite beam structure. Background Art

[0002] A composite beam is a building structure that is formed by stacking and overlapping two or more prefabricated beams (slabs) to form a floor structure. This type of structure is usually formed by pouring some concrete after the prefabricated slabs are installed in place to connect the prefabricated beams into a whole, thus forming the so-called composite beam. The cross-section of a composite beam is generally rectangular or T-shaped, but in some cases, such as when the floor structure is a prefabricated floor, in order to reduce the height of the structure and increase the building clearance, the frame beam cross-section often adopts a cross or basket shape. In the assembled integral frame structure, the prefabricated beam is often made into a T-shaped cross-section to further optimize the structural performance.

[0003] The concept of composite beams also includes a structural form called high-strength reinforced composite beams, in which the columns (or shear walls) are cast in situ, the slabs are cast in situ flat plates or new cast in situ multi-ribbed slabs, and the beams are prestressed composite beams. This structural form combines the use of high-strength steel bars to further improve the overall performance and durability of the structure.

[0004] In summary, a composite beam is a floor structure formed by superimposing and overlapping precast beams (slabs). Its characteristics include reducing the height occupied by the structure, improving the overall performance and durability of the structure, and in certain cases connecting the precast beams into a whole through cast-in-place concrete.

[0005] The problem with the prior art is that, when the prefabricated composite beams are hoisted and placed on the supporting columns, there is a lack of corresponding positioning measures, and the beam body is in a movable state, which can easily affect the accuracy of building construction and there is a certain risk of falling off; when the composite beams are installed, the steel bars of adjacent beam bodies are easily interfered with each other, requiring on-site correction, making the installation operation inconvenient and the construction efficiency low.
