Description

The lightweight steel construction that truss combination beams is connected with levels and job practices thereof
Technical field
The present invention relates to a kind of lightweight steel construction and job practices thereof, particularly a kind of lightweight steel construction and job practices thereof for lightgage steel joist system house.
Background technology
But the lightgage steel joist building systems has, and quality is light, anti-seismic performance good, thickness of wall body is little, thermal and insulating performance is good, construction pollution is little, speed of application is fast, need not to touch plate, pipeline arrangement convenience, remaining years discarded object are few, can promote energy-conserving and environment-protective batch production production and can promote the advantage of building industry development, therefore at home and abroad is widely used in the building trade in recent years.
In present lightgage steel joist building systems, body of wall truss principal and truss combination beams adopt two kinds of ways: 1, traditional C type light gauge cold-formed steel shape truss principal and truss combination beams namely is to be body of wall truss principal and the truss combination beams that C type light gauge cold-formed steel shape is formed by connecting by self-tapping screw by the cross section; The shortcoming of this way is, because the Width on C type light gauge cold-formed steel shape cross section web and the edge of a wing is larger, easily cripling occurs and reduce element bearing capacity under the axial load effect.2, closed side's square type light gauge cold-formed steel shape truss principal and truss combination beams namely are to be body of wall truss principal and the truss combination beams that closed side's square type light gauge cold-formed steel shape is formed by connecting with self-tapping screw by the standard connector by the cross section; The advantage of this way is because square tube is the closed type steel pipe, so be difficult for occuring cripling under the axial load effect, bearing capacity is high.
Present lightgage steel joist building systems has following some shortcoming: 1, the every one deck body of wall truss principal at the lightgage steel joist building systems includes body of wall sheet post, is connected to the upper tube connector between the top of body of wall sheet post and is connected to lower tube connector between the bottom of body of wall sheet post, the upper chord of the floor beam in the truss combination beams directly is shelved on the upper tube connector of lower floor's body of wall truss principal, and the lower tube connector of upper strata body of wall truss principal is pressed on the upper chord of floor beam.The floor beam of this structure can't directly be connected with levels body of wall truss principal simultaneously, the upper chord that can only be floor beam rides over arbitrarily on the upper tube connector of lower floor's body of wall truss principal, although so easy for installation, but insecure, the partial pressing of floor beam is difficult for satisfying force request simultaneously, floor beam has a little less than the bearing capacity, the shortcoming that steadiness is poor, and, floor beam directly rides over the words on the upper tube connector of lower floor's body of wall truss principal, because tube connector will directly bear floor beam and upper strata load, so cause easily floor beam, vibration and distortion occur in tube connector and floor plate, and destroy thus the flooring decorative layer, produce sense of insecurity.
2, the connected mode of closed side's square type light gauge cold-formed steel shape truss combination beams rod member is welding, bolt connection or self-tapping screw connection etc.Welding is the direct connected mode of the first between the light gauge cold-formed steel shape truss member, although this connected mode bearing capacity greatly, does not need contact panel, the welding job amount is large, take a lot of work, and because steel truss rod member cross section is thinner, welding operation is very inconvenient, and welding quality is difficult to be guaranteed; With bolts by gusset plate is the second connected mode between the light gauge cold-formed steel shape truss member, the layout of the shape of each gusset plate and bolt hole can be decided according to the internal force of rod member around the node on the truss, generally all not identical, this brings very burden for making and the processing of truss, and the perforated area of bolt hole is too large, it is too many that the cross section weakens, so use few; Linking to each other by metal sheet and self-tapping screw, to solve the panel point problem be the third connected mode between the light gauge cold-formed steel shape rod member, but present gusset plate generally is designed to flat board, without the punching press beading, without flange, and it is not general, and for making things convenient for the installation of self-tapping screw, gusset plate is generally thinner, easily local buckling occuring during pressurized and has reduced the supporting capacity of panel point, in addition, need in advance punching on each gusset plate, so that self-tapping screw is in place, this has increased again the workload that node is made virtually, makes construction inconvenient.
3, body of wall sheet post is steel column structure form commonly used in the steel work, its common way that is connected with the basis is in the post bottom surface base plate to be set, the post two sides arrange the boots beam, if bearing capacity is inadequate, can also between the boots beam, increase dividing plate, outside the boots beam, floor is set, this suspension column form is connected insecure with the basis, there is simultaneously complex structure, inconvenience is installed in processing, can't carry out intensive production, the shortcoming that construction precision is not high, in addition, the job site need to be cut and weld member, and is higher to site operation personnel's technical requirements, on-the-spot heat construction workload is large, simultaneously easily at the construction field (site) breaking out of fire have potential safety hazard.
