Description

Lightweight steel construction that the truss compound beam 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 that is used for lightgage steel joist system house.
Background technology
But the lightgage steel joist building systems has light weight, anti-seismic performance is 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, pipe line arrangement is convenient, the remaining years discarded object is few, can promote energy-conserving and environment-protective batch production production and can promote the advantage of building industry development, has therefore at home and abroad obtained using widely in the building trade in recent years.
In present lightgage steel joist building systems; Body of wall truss principal and truss compound beam adopt two kinds of ways: 1, traditional C type light gauge cold-formed steel shape truss principal and truss compound beam promptly is to be body of wall truss principal and the truss compound beam that C type light gauge cold-formed steel shape is formed by connecting through self-tapping screw in the cross section; The shortcoming of this way is, because the width on the C type light gauge cold-formed steel shape cross section web and the edge of a wing is bigger, and easy generation cripling under the axial load effect and reduce element bearing capacity.2, closed side's square type light gauge cold-formed steel shape truss principal and truss compound beam promptly are to be body of wall truss principal and the truss compound beam that closed side's square type light gauge cold-formed steel shape is formed by connecting with self-tapping screw through the standard connector in the cross section; The advantage of this way is because square tube is the closed type steel pipe, so under the axial load effect, be difficult for taking place cripling, bearing capacity is high.
Present lightgage steel joist building systems has following some shortcoming: 1, each layer body of wall truss principal at the lightgage steel joist building systems include body of wall sheet post, be connected between the top of body of wall sheet post on tube connector and be connected the following tube connector between the bottom of body of wall sheet post; The upper chord of the floor beam in the truss compound beam directly is shelved on the last tube connector of lower floor's body of wall truss principal, and the following tube connector of upper strata body of wall truss principal is pressed on the upper chord of floor beam.Though the floor beam of this structure can't directly be connected with levels body of wall truss principal simultaneously, can only be that the upper chord of floor beam rides over arbitrarily on the last tube connector of lower floor's body of wall truss principal, so easy for installation; But insecure, simultaneously the partial pressing of floor beam is difficult for satisfying force request, and floor beam has that bearing capacity is weak, the shortcoming of steadiness difference; And; Floor beam directly rides on the last 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 floor beam, tube connector and floor plate that vibration and distortion take place easily; And destroy the flooring decorative layer thus, produce sense of insecurity.
2, the connected mode of closed side's square type light gauge cold-formed steel shape truss compound beam rod member is welding, bolt connection or self-tapping screw connection etc.Welding is first kind of direct connected mode 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 big; Take a lot of work; And because steel truss rod member cross section is thinner, welding operation is inconvenience very, and welding quality is difficult to be guaranteed; Adopting bolt to connect through gusset plate is second kind of 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 inequality, this brings very burden for the making and the processing of truss, and the perforated area of bolt hole is too big; It is too many that the cross section weakens, so use few; Through metal sheet and the continuous solution of self-tapping screw panel point problem is the third connected mode between the light gauge cold-formed steel shape rod member, but present gusset plate generally is designed to flat board, no punching press beading; No flange, and not general, and for making things convenient for the installation of self-tapping screw; Gusset plate is generally thinner, easily local buckling takes place during pressurized and has reduced the supporting capacity of panel point, in addition; Need punching in advance on each gusset plate; So that self-tapping screw is in place, this has increased the workload that node is made virtually again, makes construction inconvenient.
3, body of wall sheet post is a steel column form of structure commonly used in the steel work, and its common way that is connected with the basis is in the post bottom surface base plate to be set, and the post two sides are provided with the boots beam; If bearing capacity is not enough, 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, have complex structure, installation and processing inconvenience, the not high shortcoming of production, construction precision that can't intensify simultaneously, in addition; The job site need be cut and weld member; Technical requirements to the site operation personnel is higher, and on-the-spot heat construction workload is big, simultaneously easily at the construction field (site) breaking out of fire have potential safety hazard.
