A light steel structure house and its construction method

Abstract

The invention relates to a light-weight steel structure house and a construction method thereof. The light-weight steel structure house comprises a house frame, double-layer outer wall plates, inner wall plates and lightweight floor plates. The house frame comprises a foundation, supporting upright columns, truss beams and cross sleeve connecting pieces; the supporting upright columns comprise four corner supporting upright columns, a plurality of outer supporting upright columns and a plurality of inner supporting upright columns; each supporting upright column is of an I-shaped steel structure; and the supporting upright columns are mounted on the foundation in mutually-parallel mode. The double-layer outer wall plates are arranged between every two adjacent outer supporting upright columns or between the adjacent corner supporting upright columns and the outer supporting upright columns. The inner wall plates are arranged between every two adjacent inner supporting upright columns or between the adjacent inner supporting upright columns and the outer supporting upright columns. The lightweight floor plates are parallelly arranged between every two adjacent truss beams. The light-weight steel structure house and the construction method thereof have the advantages that by means of the house frame, the double-layer outer wall plates, the inner wall plates and the lightweight floor plates and adjustment of connection of all the structures, the house is convenient for correction, effective heat dissipation and noise reduction are achieved, and meanwhile the overall strength of the house is guaranteed.

Description

technical field [0001] The invention relates to the field of construction, to a construction structure and a construction method, in particular to [0002] A light steel structure house and a construction method thereof. Background technique [0003] With the economic construction and social development, there are more and more light steel structure buildings. With the country's advocacy of energy-saving and low-carbon buildings, light-weight steel structure housing has been vigorously developed as a green, environmentally friendly and energy-saving housing system. The light steel structure residence has the advantages of short construction period, light weight, earthquake resistance, sound insulation performance, and good thermal insulation performance. As the concrete wall panel occupies a large proportion in the low-rise prefabricated light steel structure residence, its influence on the whole system cannot be ignored. The new type of low-rise prefabricated steel struc...

[0006] After searching, the patent CN 205617554 U discloses a prefabricated light steel structure house, such as figure 1 As shown, it includes a foundation 1a, a ground floor prefabricated room body 2a and an upper floor prefabricated room body 3a, the foundation 1a is provided with a foot foundation 4a, and the foot foundation 4a is provided with more than one, and the side of the foundation 1a is provided There is an outer wall frame partition 5a, and the outer wall frame partition 5a is fixed to the foot foundation 4a, and the middle part of the foundation 1a is provided with an inner wall frame partition 6a, and the outer wall frame partition 5a and the inner wall frame partition 6a A floor fixing frame 7a is arranged above, and the floor fixing frame 7a is fixed with the outer wall frame partition 5a and the inner wall frame partition 6a, and the bottom prefabricated room 2a is fixed with the foundation 1a, and the bottom prefabricated room 2a Window frames 8a are arranged on both sides, the upper prefabricated room body 3a is located above the bottom prefabricated room body 2a, a backing plate 9a is arranged below the upper layer prefabricated room body 3a, and the upper layer prefabricated room body 3a is provided with The top plate 10a, the bottom of the top plate 10a is provided with a roof bracket; but the prefabricated light steel structure house of this structure has certain disadvantages: the prefabricated structure of the patented house is not conducive to the correction process after matching

[0007] After searching, it is also found that the patent CN 203977626 U discloses a load-bearing wall of a light-weight steel structure prefabricated house, such as figure 2 As shown, it includes a wall column 2b, the upper end of the wall column 2b is provided with a top beam 3b, and the lower end of the wall column 2b is provided with a bottom beam 1b, and the bottom beam 1b is fixed on the concrete foundation through an anchor bolt. Together, an outer support is provided on the outside of the wall column 2b, an inner support is provided on the inner surface of the wall column 2b, an outer corner 5b is provided at the end of the load-bearing wall, and an inner corner 6b is provided at the middle of the load-bearing wall , a lintel 4b is arranged above the door and window openings of the load-bearing wall; the above-mentioned patent, as a load-bearing wall structure of a light-weight steel structure assembly, only plays a load-bearing effect, but cannot reflect the thermal insulation performance required for the load-bearing outer wall , and a single-layer exterior wall structure is adopted; in addition, the above-mentioned load-bearing interior wall panels are installed inside the house. Although the load-bearing wall structure solves the load-bearing problem of the wall to a certain extent, the noise reduction performance of the wall Poor, and use a monolithic wall structure

[0008] In addition, the floor slabs used for the roof structure of the existing light-gauge steel structure prefabricated houses have a single structure and high cost. The floor slab only adopts a set of C-shaped steel structure, and it is located in the extension direction of the floor. There is no C-shaped steel at both ends of the floor, which leads to the fact that the end of the floor cannot be welded with the truss beam. Only a set of C-shaped steel structures along the extension direction of the floor is used. C-shaped steel welding can easily lead to insufficient welding strength of the whole house
