Abstract
The invention discloses a construction method of a lattice light-gauge steel house. The construction method of the lattice light-gauge steel house comprises the following steps of foundation treatment, wall body construction, and storied building panel construction. The construction method of the lattice light-gauge steel house is ingenious in design and simple in process, the light-gauge steel house has better structure strength and earthquake resistant property, and construction material cost is reduced. The storied building panels and the wall body are formed by removal-free templates and plaster at a time, and plaster processing is not needed. Metal meshes and cement mortar are combined closely, the quality common faults of hollow bulge and the like caused by traditional secondary plastering are overcome, and additional heat-preservation and thermal-insulation materials and secondary construction procedures are not needed.
Description
Technical field
The present invention relates to a kind of construction method of building, especially a kind of construction method of lattice light-gauge steel house.
Background technology
Current building construction generally can be divided into brick mixed building body structure, reinforced concrete structure (framework, frame are cut, shear wall) and steel work (normal steel structure, lightweight steel construction) by form of structure, wherein lightweight steel construction generally has two kinds of forms, is respectively cold-formed thin-walled C steel structure and light-wall pipe purlin lightweight steel construction.Light steel structure house is the advantage such as wall is thin, light weight, installation rate are fast, anti-seismic performance good, pipeline arrangement convenience owing to having, and is at home and abroad widely used in low layer and multistoried building.
The light steel house of tradition is in actual applications because its many performance indications and ordinary concrete or masonry structure still have larger gap, so be difficult to allow user accept completely, the heat preservation and soundproof weak effect of such as floor and roof panel, when people walks on floor, floor easily trembles, when raining, roof panel noise is large, and floor feels shaky etc.; In addition, the floor of traditional lightweight steel construction and the installation procedure complexity of roof panel, cost is high.
Light steel structure house is made up of the part such as body of wall, building panel.Traditional body of wall and building panel formwork way first prop up bed die (with punching block or wooden model), and brush release agent, then concreting, reach form removal again after some strength until concrete, have enough to meet the need as secondary.This construction technology is due to formwork form removal twice, in addition concrete setting is waited in the middle of, need the long period, in addition due to the impact of concrete match ratio when construction environment (temperature and humidity), striking time is difficult to accurate assurance, easily causes the common quality defects such as concrete component losing fangle, pitted skin, dew muscle when form removal.Due to the existence of these common quality defects, can cause again after plastering at the bottom of plate and form hollowing phenomenon, use to ornament and bring problem.
Application number is the construction method that the Chinese patent application of 2009103028467.X discloses a kind of lightweight steel construction floor: step one, the light steel skeleton top of body of wall erection square steel pipe, by the two end supports of two string ladder beam on the square steel pipe at body of wall top, both sides, the upper and lower chord member of two string ladder beam lays respectively at the upper and lower of square steel pipe, and two string ladder beam is intervally arranged on flooring by design; Step 2, two string ladder beam be equipped with the die-cut expansion of muscle draw in the net, with self-tapping screw connect above-mentioned both; Step 3, have the die-cut expansion of muscle draw in the net on cast-in-place concrete, formed concrete cast surface layer.Application number be 200910302847.4 China application discloses that a kind of construction method of lightweight steel construction body of wall, scalariform post both sides connect non-dismantling formwork net, fill concrete pouring layer in wall body construction cavity, and then smear cement mortar outside non-dismantling formwork net.The first cast wall of the method, then cement mortar is smeared inside and outside body of wall.Above-mentioned two kinds of construction methods due to reasons such as casting qualities, after smear mortar and very easily form the common quality defect such as hollowing, crack.Simultaneously owing to adopting ordinary concrete as deck, reach the requirement of national compulsory heat preservation energy-saving also needs to increase other heat insulation measure.
Summary of the invention
The object of this invention is to provide a kind of construction method of lattice light-gauge steel house.This construction method is skillfully constructed, simple process, makes light steel house have better structural strength and anti-seismic performance; Building panel and body of wall realize non-dismantling formwork and plaster one-shot forming, do not need to remake process of plastering; Wire lath is combined closely with cement mortar, overcomes traditional secondary and to plaster the common quality defects such as the hollowing that easily formed; Without the need to additional heat preserving and insulating material and secondary construction sequence.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:
A construction method for lattice light-gauge steel house, comprises the following steps:
A, based process:
A1, by designing requirement construction basis;
A2, light steel quarter bend and standard connector are fixed together formation light steel keel frame, described light steel keel frame is installed on basis;
A3, by designing requirement, hydroelectric facility pipeline is installed;
B, wall construction:
B1, to be fixedly connected with in light steel keel frame both sides and to exempt to tear wire lath open;
