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 oft

Example Embodiment

[0093] Example one

[0094] The first embodiment is an integrated structure of prefabricated building cast-in-place laminated formwork, which includes a shear wall member 55, a laminated column member 56, a laminated beam member 59, a laminated plate member, an inner partition wall member 58, Peripheral retaining wall member 57, stair member 60 and balcony member 61;

[0095] The above-mentioned components are connected by sleeve grouting, and then concrete is poured from the grouting hole to connect as a whole, thereby forming an integrated structure of the prefabricated building with cast-in-place laminated formwork;

[0096] The superimposed column member 56 and the shear wall member 55 are connected by sleeve grouting, pressure casing or local spalling bars;

[0097] The outer retaining wall member 57 is connected with the shear wall member 55 or the laminated column member 56 by using the concealed column partial rejection reinforcement;

[0098] The vertical connection of the inn...

Example Embodiment

[0119] Example two

[0120] The second embodiment is a construction method of an integrated structure of cast-in-place laminated formwork in a prefabricated building:

[0121] The construction method is mainly divided into two parts: the production and processing method of the formwork component and the construction and installation method of the formwork component;

[0122] Production and processing methods of main mold shell components:

[0123] 1. After the completion of all kinds of mold shell component drawings, deepen the mold shell component drawings into mold shell processing drawings, including the accurate size of each mold shell component section, the configuration of skeleton steel or steel wire, and the specifications, models, and other materials of insulation boards and other materials. Positioning and size of prefabricated pipelines, detailed drawings of material specifications and shapes of embedded parts, hook positions and sizes, positioning and fixing parts, and inf...

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...
