2) influence architectural appearance and use: the structure of the node of cast-in-situ floor beam slab often has with architectural appearance and function of use and conflicts, and cause the layout of superstructure beam slab dumb, girder system complicated layout as the twin beams node, and single beam joint makes the width of building roof beam excessive, not only increase dead load but also cause waste of material, and influence the attractive in appearance of superstructure;
3) application of node is dumb: at present applied node all only is applicable to conventional situation in the engineering, comparatively special superstructure is arranged, and as nonopiate girder system, the absolute altitude of each beam and square one not highly, its application just has been subjected to certain restriction.
2. the node of building roof beam conitnuous forms
Its main thought is: keep the continuity of concrete floor system, each floor covers at the bottom of the beam face of beam column junction and beam and is connected with steel pipe column.
This category node has solved the connectivity problem of building roof beam and steel core concrete column, but still has following problem:
1) the post steel pipe is not communicated with the transmission capacity that has weakened its shaft pressuring load significantly in node area, though the ring beam of being furnished with circumferential reinforcement by setting can solve the axial bearing capacity problem, axial deformation is bigger than normal, and it is bigger to the stressed influence of structural entity;
2) the moment of flexure transmission of the joint face of post steel pipe at the bottom of beam face, beam and shearing transmission capacity are poor, and corresponding structure is handled the complexity of the consumption and the structure that have increased material again;
3) the centering difficulty of last lower prop in the construction;
4) steel pipe needs every layer of lifting, fixing, and construction is not easy when using in super highrise building.
