A dense column system for prefabricated concrete houses

Abstract

A dense column system for a prefabricated concrete house. The square prefabricated concrete wall columns are sprayed with light slurry to form a load-bearing wall. The outer side of the load-bearing wall is equipped with a thermal insulation and decorative integrated board, and the inner side of the load-bearing wall is installed with gypsum boards; the square prefabricated concrete wall The columns and special-shaped precast concrete corner columns are divided into several layers, and the layers are connected by precast concrete beams, and the upper end is embedded with a sleeve, and the lower end is fixed in the prefabricated strip foundation with a cup mouth or the cup mouth of the precast concrete beam; the precast concrete beam Bolt holes are provided in the mouth of the cup, and the bolts pass through the bolt holes to connect with the square precast concrete wall column and / or the pre-embedded sleeve at the upper end of the special-shaped precast concrete corner column under the precast concrete beam. Prestressed laminated panels are used for the floor and roof, and prefabricated dormer windows are used for sloping roof dormer windows. The dense column system of the prefabricated concrete house is spliced ​​and assembled by prefabricated concrete components on site, and the components are connected by bolts, which reduces the amount of wet work on site and improves the assembly rate and construction speed.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a dense column system for a prefabricated concrete house. Background technique [0002] The concrete dense column system house is an improvement based on the cold-formed thin-walled steel system. The load-bearing system is different from the concrete frame system and the brick-concrete system. The square prefabricated concrete wall column system is used for load-bearing. [0003] With the deepening of my country's reform and opening up, cold-formed thin-walled steel light steel houses from abroad have entered our country, and the main technology has been introduced to low-rise villas in Japan, the United States, Australia and other countries. After decades of development, the cold-formed thin-walled light steel system has reached a certain scale in China, but the market recognition and acceptance by the common people are not very optimistic. People who are accus...

Problems solved by technology

[0004] Traditional low-rise residences are mostly brick-concrete structures and frame structures, with heavy on-site wet work and a low degree of mechanization. In addition, the demographic dividend in my country is gradually fading out. At the same time, under the policy of vigorously advocating residential industrialization in my country, there is an urgent need to improve or update the original system. system, and the patent of the present invention is proposed based on the above problems and the current situation
