Manufacturing and mounting method for combined wall of fabricated house

Abstract

A manufacturing and mounting method of a combined wall for a fabricated house comprises the steps that firstly, a plurality of outer walls and inner walls are prefabricated, each outer wall is provided with a light microcrystalline plate and a concrete wall layer, each inner wall is provided with a concrete wall layer, and a plurality of floor connecting pieces are arranged on the top sides of ceiling keels of the outer walls and the inner walls in a penetrating mode through a plurality of connecting bolts; a plurality of foundation bolts are arranged on the bottom sides of the ground keels of the outer wall body and the inner wall body in a penetrating mode; a concrete foundation is manufactured, a plurality of wall body mounting holes are machined in the concrete foundation, then the wall body mounting holes are filled with grouting materials, the outer wall body and the inner wall body are hoisted to the concrete foundation, and the foundation bolts are inserted into the wall body mounting holes respectively; and the floor slab is hoisted to the top side of the bottommost layer of combined wall body, and the outer wall body and the inner wall body are hoisted to the lower layer of combined wall body layer by layer. The combined wall can be prefabricated in a factory or on site, wet operation of concrete pouring on site is avoided, and the installation precision is easy to control.

Description

technical field [0001] The invention relates to the field of prefabricated houses, in particular to a method for manufacturing and installing a combined wall used in a prefabricated house. Background technique [0002] Lightweight steel structure prefabricated houses have the advantages of light weight, good seismic performance, short construction period, energy saving and environmental protection, and high degree of industrialization. Its shortcomings seriously affect its promotion and application. The combined walls of existing prefabricated houses are usually prefabricated in the factory or on site, so wet work of pouring concrete is required on site, the installation accuracy is not easy to control, and the combined walls are prone to overall and local instability and corrosion. The thermal insulation, fire prevention and sound insulation performance are poor, and the cost and installation cost are high, which limits the production of large quantities of light steel kee...
