Description

A long-span rib beam prefabricated reinforced concrete composite thermal insulation external wall hanging board

technical field

The utility model belongs to the technical field of civil engineering, in particular to a long-span rib-type prefabricated reinforced concrete composite thermal insulation external wall hanging board.

Background technique

As the component with the largest surface area in construction engineering, the enclosure wall panel is one of the important components of the building. It not only bears the external load, but also can block the heat exchange between indoor and outdoor. At present, there are three main types of thermal insulation wall panels: external thermal insulation, internal thermal insulation, and prefabricated sandwich thermal insulation. However, there are more and more large-span projects, and the above insulation wall panels can no longer meet the project requirements. The cost of external insulation is high and the construction is difficult, especially the high-rise construction technology requirements are high, which affects the decoration of the external wall. The insulation effect of the inner insulation is poor, the wall is cold, the insulation layer is hot, and the temperature difference between the inside and outside forms condensed water. Prefabricated sandwich insulation is a prefabricated reinforced concrete composite thermal insulation wall panel connected by steel trusses. The inner and outer blades are thick, self-heavy, and the integrity is not good, so it is not suitable for large spans. The connecting parts adopt steel truss, which is easy to conduct heat, has poor thermal insulation performance, and cannot achieve the expected thermal insulation effect.

Utility model content

The technical problem to be solved by the utility model is to provide a hanging board suitable for large-span rib-beam composite thermal insulation external walls. Compared with the traditional thermal insulation board, the lateral stiffness of the composite board is improved, the weight of the composite board is reduced, and the amount of materials is reduced. It is suitable for large spans, reduces costs, improves thermal insulation effects, and is convenient and quick to construct.

In order to solve the above-mentioned technical problems, the utility model provides a large-span rib beam prefabricated reinforced concrete composite thermal insulation external wall hanging panel, which includes an inner leaf plate, an outer leaf plate, an insulating layer, horizontal steel bars, and vertical steel bars, and is characterized in that: Rib beams are arranged on the leaf plate, and the inner leaf plate and the outer leaf plate are connected by carbon fiber rods.

The shape of the carbon fiber rod is Z-shaped.

Rib beams criss-cross to form a grid structure.

The utility model improves the overall rigidity and reduces the self-weight by adding rib beams, and at the same time relies on the bonding force between the carbon fiber rods with a low heat transfer coefficient and the concrete to connect the inner and outer blades, further enhancing the integrity of the structure and improving the bearing capacity. capacity, to ensure the safety of the construction and use phases, and to avoid the appearance of cold bridges.
