Cast-in-place superposed formwork integrated structure of prefabricated building and construction method

Abstract

The invention relates to a cast-in-place superposed formwork integrated structure of a prefabricated building and a construction method and belongs to the field of building engineering. The structurecomprises shear wall members, superposed column members, superposed beam members, superimposed slab members, inner partition members, peripheral guard wall members, stair members and balcony members.The members are connected through sleeve grouting and then connected into a whole by grouting concrete from grouting holes, so that the cast-in-place superposed formwork integrated structure of the prefabricated building is formed. The integrated structure is used for constructing the prefabricated building; all nodes of the building have the same performance as cast-in-place nodes; and the prefabricated building has the same integrity as cast-in-place building and excellent shock resistance, water resistance and sound insulation performance.

Description

technical field [0001] The invention relates to an integrated structure and construction method of cast-in-place laminated formwork for an assembled building, belonging to the field of construction engineering. Background technique [0002] With the continuous development and progress of new building technology and materials, the extensive traditional cast-in-place construction technology gradually cannot meet the needs of my country's building industrialization, and prefabricated buildings have regained new vitality in my country. In many countries with developed building industrialization, prefabricated buildings have undergone long-term experiments and applications. Modern prefabricated building products have been able to highly integrate various functions of the building. Compared with traditional building houses, it has reduced wet work and faster construction. Advantage. [0003] Prefabricated building planning has been introduced intensively since 2015. The state has...

Problems solved by technology

Although the research and application of prefabricated concrete structures in my country has made great progress, there are many studies on the performance of joints and components of prefabricated structures, but there is not enough research on the overall performance, only focusing on strong joints and weak components, and the seismic performance remains to be seen. At the same time, the existing prefabricated system nodes can better realize the requirements for bearing capacity and stiffness, but the ductility often fails to meet the requirements, and the bearing capacity, stiffness and ductility of the nodes are not up to the similar cast-in-place structures. degree, there is a certain security risk

In addition, the waterproof problem of the prefabricated concrete building joints cannot be ignored. The existing prefabricated buildings are different from the overall cast-in-place construction on site. The joints of the building have common quality problems of leakage, and the sound insulation and heat resistance are also poor.
