Prefabricated building prefabricated steel concrete intermediate column-beam joint prestressed tendon interlaced tension anchorage structure and construction method

Abstract

The invention discloses a prefabricated steel-concrete intermediate column-beam node interlaced tension anchoring structure for prefabricated buildings. Formed cross-shaped steel column; prefabricated column laminate layer arranged on the upper part of the prefabricated column; laminated beam arranged at one end of the prefabricated column; top steel bars exposed on the upper part of the The outstretched reinforcement on the side of the prefabricated column; the multiple reserved perforations on the cross-shaped steel column; the prestressed tendons passing through the multiple reserved perforations; the prestressed steel bars fixed on the cross-shaped steel column A tendon anchoring device, the prestressed tendons are fixed on the cross-shaped steel column through the prestressed tendon anchoring device; this structure ensures the integral stress requirements of the beam-column joints, and makes the joints have a good anti-negative bending moment effect.

Description

technical field [0001] The invention relates to a post-beam connection node structure and a construction method of an assembled building, in particular to a prestressed tendon staggered tension anchoring structure and a construction method of a prefabricated steel-concrete intermediate post-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 construction industrialization, prefabricated buildings have undergone long-term experiments and applications. Modern prefabricated building products can 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 buildings, so the requirements for the node structure...

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] In terms of the existing technology, the main problem of the prefabricated steel-concrete intermediate column-beam joint prestressed tendon cross-tensioned anchorage structure of prefabricated buildings is that the stress of beam-column joints cannot be effectively improved without the development and use of superimposed prestressing technology The characteristics of the beam-column joints cannot guarantee the integrity of the force requirements, and the negative bending moment resistance of the joints is poor; the current construction method of the prefabricated steel concrete intermediate column-beam joint prestressed tendon cross-tensioned anchorage structure of prefabricated buildings has the following problems: High hoisting cost, low hoisting speed and precision, which brings great difficulties to construction
