Fabricated building prefabricated steel reinforced concrete end column-beam joint prestressing tendon interlaced tension anchoring structure and construction method

Abstract

The invention discloses a fabricated building prefabricated steel reinforced concrete end column-beam joint prestressing tendon interlaced tension anchoring structure. The fabricated building prefabricated steel reinforced concrete end column-beam joint prestressing tendon interlaced tension anchoring structure comprises prefabricated columns, and further comprises reserved hole channels reservedin the prefabricated columns, T-shaped steel columns integrated with the prefabricated columns, prefabricated column laminated layers arranged on the upper parts of the prefabricated columns, superimposed beams arranged at one ends of the prefabricated columns, top steel bars exposed to the upper parts of the superimposed beams, external extension steel bars extending outside the sides of the prefabricated columns, a plurality of reserved penetrating holes formed in the T-shaped steel columns, prestressing tendons penetrating through the multiple reserved penetrating holes, and prestressing tendon anchoring devices fixed to the T-shaped steel columns, and the prestressing tendons are fixed to the T-shaped steel columns through the prestressing tendon anchoring devices. The structure ensures the overall stress requirements of beam-column joints and enables the joints to have a good hogging moment resisting effect.

Description

technical field [0001] The invention relates to a structure and a construction method of a column-beam connection node of an assembled building, in particular to a structure and a construction method of a prestressed tendon cross-tensioned anchorage structure and a construction method of a prefabricated steel concrete end column-beam node of an assembled building. Background technique [0002] In recent years, with the continuous development and progress of new building technologies and materials, prefabricated buildings have been widely used. In many countries with developed building industrialization, prefabricated buildings have experienced long-term experiments and applications. Modern prefabricated building products can already highly integrate various functions of buildings, and the forms and components of buildings are very delicate. [0003] my country's construction demand is large and the construction speed is fast. It is necessary to develop prefabricated buildi...

Problems solved by technology

Traditional prefabricated structures have high hoisting costs and low hoisting speed and precision, which brings great difficulties to building construction. If the hoisting of prefabricated buildings wants to realize industrial modernization, the hoisting methods and detailed structure design of connection nodes must be paid attention to. Need further innovative research, for this reason the present invention has made relevant creation according to the innovation of actual construction on the basis of this problem

[0004] Combining the existing technology, the main problem of the prefabricated steel concrete end column-beam joint prestressed tendon interlaced tension anchorage structure of prefabricated buildings is that the superimposed prestressing technology cannot be effectively improved without the development and adoption of superimposed prestressing technology. The force characteristics cannot guarantee the integrity of the beam-column joints, and the negative moment resistance of the joints is poor; the current construction method of the prefabricated steel concrete end column-beam joint prestressed tendon cross-tensioned anchorage structure has problems Yes: The cost of hoisting is high, and the speed and precision of hoisting are low, which brings great difficulties to the construction
