Abstract

The invention discloses a PVC-FRP pipe restrained section steel concrete column-reinforced concrete beam L-shaped node which comprises the components of two sets of circular steel pipe fasteners, a PVC-FRP pipe, core section steel, two sets of U-shaped hidden brackets, a column longitudinal rib, a column tie-rib, a beam longitudinal rib, a beam tie-rib, high-strength bolts, core-crossing anchor bolts and a stiffening rib plate. The core section steel penetrates through the center of the circular steel pipe fastener. The PVC-FRP pipe sleeves the core section steel. The two sets of U-shaped hidden brackets are fixedly connected with the two sets of circular steel pipe fasteners through high-strength bolts. The two sets of U-shaped hidden brackets are arranged in an L-shape. Core passing anchor bolt pass through the U-shaped hidden bracket. The directions of the core-passing anchor bolts in the same layer are same. The directions of the core-passing anchor bolts are opposite. The circularsteel pipe fasteners are connected through the core-crossing anchor bolt. The PVC-FRP pipe restrained section steel concrete column-reinforced concrete beam L-shaped node can realize quick splicing of steel components in the node and further has advantages of high bearing force, high integrity, convenient construction, high industrialization degree, etc.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a PVC-FRP pipe-constrained steel concrete column-reinforced concrete beam L-shaped joint. Background technique [0002] At present, construction in my country's construction industry is dominated by on-site wet operations. During the construction process, there are problems such as complex on-site procedures, unsuitable construction quality assurance, and serious environmental pollution. Therefore, traditional construction methods can no longer meet the development trend of modern construction industry. [0003] The prefabricated structure refers to the prefabricated components in the processing plant or on-site, and through certain technical means, the prefabricated components are connected into a whole structure. The prefabricated structure has the advantages of high production efficiency, convenient construction, energy saving and emission reduction. Generally spea...
