The invention provides a method for building a house through inflation molds and a mold house. The method comprises the steps of constructing a base of the house according to the bottom face shapes of a plurality of prefabricated inflation molds, fixing the inflated inflation molds to the corresponding positions of the base, inserting a building connecting component into the portion between every two adjacent inflation molds needing to be communicated from the side face, sticking a finished door, a finished window, an inflated outer window inflation mold and an outer door inflation mold to the preset positions of the surface of the inflation molds, fixing equipment pipelines to the outer sides of the inflation molds, spraying and pouring rapidly-hardened and heat preservation materials to the outer surfaces of the inflation molds, forming the materials to be sprayed and poured to obtain the stable house structure, then deflating and taking down the outer window inflation mold and the outer door inflation mold, and deflating the inflation molds to take the inflation molds out of a hole of the outer window inflation mold or the outer door inflation mold. The mold house built through the method has the advantages that building is rapid, forming is achieved at a time, stability and safety are high, and the inflation molds can be repeatedly used.

The invention belongs to the technical field of construction engineering and particularly relates to a prefabricated assembly type strip foundation and a construction technology. The prefabricated assembly type strip foundation is characterized in that the prefabricated assembly type strip foundation comprises a longitudinal rebar; a plurality of hooping ribs are wound and fixed outside the longitudinal rebar; and the longitudinal rebar and the hooping ribs serve as a whole stress body through concrete pouring. The prefabricated assembly type strip foundation has the beneficial effects that factory prefabricated production can be achieved, quality control is convenient, construction difficulty caused by outdoor weather changes is avoided, field installation is safe, fast and convenient, energy conservation and environment protection are achieved, labor and time are saved, and the assembly efficiency is high.

The invention discloses a combined long-span ribbed slab structure. The ribbed slab is formed by splitting steel form shells of different shapes; the frontages of the steel form shells of the different shapes are uniformly distributed with rivets (1), the sides of the steel form shells of the different shapes are connected through bolts, and the backs of the steel form shells of the different shapes are connected to form a slab plane through connecting plates (2) and bolts (3); a reinforced bar casting concrete layer (4) is paved on the plane of the slab and is closely connected with the plane of the slab to form the combined long-span ribbed slab through the uniformly distributed rivets (1). Compared with the prior art, the combined long-span ribbed slab structure provided by the invention has a few of combined components; furthermore, the combined long-span ribbed slab is processed in batches by a professional factory, good interchangeability and convenience in field splitting can be realized, the field labor capacity can be reduced, the construction period can be reduced significantly and the economic benefit can be improved; an existing wooden form can be substituted by the plane of the slab formed by splitting the steel form shells, therefore, the compressive property can be improved and the cost saving can be realized; in addition, lightening holes are formed in side plates, therefore materials can be saved and dead weight can be reduced.

The invention discloses a masonry building concrete filled steel tubular column pedestal shock isolation foundation structure and a construction method thereof. The masonry building concrete filled steel tubular column pedestal shock isolation foundation structure comprises a building peripheral outer wall shock isolation foundation and a building peripheral inner wall shock isolation foundation; the building peripheral outer wall shock isolation foundation is composed of a lower part structure, a peripheral upper supporting beam and an upperpart structure; the peripheral upper supporting beam and the upperpart structure are arranged above the lower part structure; and shock isolation devices are arranged between the peripheral upper supporting beam and the lower part structure as well as between a middle upper supporting beamand the lower part structure respectively. The construction method comprises the following steps: arranging the shock isolation devices; arranging the upper supporting beams; prefabricating a shock isolation device component; excavating earthwork; detecting the lower part structure; carrying out location and line laying of the shock isolation devices; installing the shock isolation devices; carrying out reinforcement operation on the shock isolation devices; constructing the upper supporting beams; filling sealing materials; constructing concrete composite slabs; and constructing earth-retaining walls and scattered-water concrete. The masonry building concrete filled steel tubular column pedestal shock isolation foundation structure is low in construction cost and ensures the service life when reducing the backfilling engineering quantity of an indoor foundation.

The invention discloses a modular assembly house system, which is characterized in that it includes one or more modular houses (1), and the houses (1) within two floors extend infinitely in the horizontal direction, Each house (1) is composed of a steel structure frame (2), a cold-formed thin-walled steel system wall panel (3), a cold-formed thin-walled steel system floor plate (4) and a cold-formed thin-walled steel system roof (5) Composition; described steel structure frame (2) comprises crossbeam (2.1) and vertically connected column (2.2) that are parallel to each other up and down, and the eight corners that described beam (2.1) and column (2.2) surround are all used The connecting piece (7) is connected; it overcomes the disadvantages of inconvenient folding and assembly in the prior art, poor combination, and unsuitability for complicated environments, and has the advantages of detachable, interchangeable, and increase-reducible.

The invention discloses an implementing method of a fabricated under-rail foundation of a tramcar in a soft soil area. The implementing method comprises the steps that three parts of components of PHCpile foundations, reinforced concrete cross beams and reinforced concrete slab structures are prefabricated in a factory; steel bars are reserved in the position, corresponding to the pile foundations, of prefabricated roadbed beams, after under-beam steel bars and steel plates at the tails of the under-beam steel bars are placed in prefabricated pile hollow parts, shearing pin son-openings are reserved in the prefabricated reinforced concrete cross beams, during fabricating, shearing pin mother-openings in the prefabricated reinforced concrete slab structures and the shearing pin son-openings in the prefabricated reinforced concrete cross beams are subjected to socket welding to form a common beam-slab force-transferring structure; and different slab blocks of prefabricated reinforced concrete slabs are lapped on the cross beams. The implementing method has the beneficial effects that prefabricated components are adopted, the manufacturing precision is high, the quality is ensured, meanwhile, the on-site installation efficiency and installation precision are improved, on-site labor force can be saved, the construction period is shortened, and the integrity of the roadbed structure is improved; and an under-rail foundation structure of the tramcar can be completed quickly, safely, and efficiently in an environmentally friendly mode.

The invention provides a prefabricated steel concrete shear wall prefabricated structure assembly building, the building has a prefabricated structure in the factory, including prefabricated steel concrete shear walls, prefabricated steel concrete beams, reinforced truss concrete floors, prefabricated reinforced concrete stairs, A lightweight masonry partition wall and a prefabricated foam concrete exterior wall; and an installation method for the prefabricated steel concrete shear wall prefabricated structure prefabricated building is also provided.
