Description
Technical field
The invention belongs to steel structure truss technical fields.
Background technique
With the continuous development of Chinese society economy, increasingly higher demands are proposed to the structure and function of building, are removed
Meet outside people's daily work life demand, it is also often desirable to meet the needs of some special occasions, wherein there is exhibitions function
The large span of energy, the tier building of large space are applied more and more.And traditional reinforced concrete structure is by its structure and construction
The limitation of technique is difficult to construct the building of large span large space floor.And existing steel building, mainly use round steel truss
It constructs large span large-spatial structures system, then is laid with or pours build floor on steel structure system, but due to existing circle
The limited load bearing capacities of steel truss, the building span constructed to ensure safety and space can not be excessive.In addition, it is constructed
Complexity, high construction cost cause using limited.
Summary of the invention
Purpose of the utility model is to solve the deficiencies in the prior art, comply with the direction of modern architecture development, provide
A kind of structural strength is high and simple and reliable, economical and efficient large-span steel truss.
The purpose of this utility model is achieved through the following technical solutions:
A kind of large-span steel truss is in profound bar on the upright H-type section being vertically arranged, web in level including web
Under the horizontal H-type section being arranged profound bar, upper and lower ends be respectively welded Yu Shangxuan bar bottom plate and under equidistantly setting on profound bar web
It is the vertical round steel pipe web member set, symmetrical in the diagonal brace round steel pipe abdomen being diagonally welded between adjacent two vertical round steel pipe web members
Bar；The length of profound bar, entire large span steel truss shape are trapezoidal under the length of the upper profound bar is greater than.
The utility model is located at vertical round steel pipe web member in the groove of profound bar web lower part under and Xia Xuan bar intersection welds
It is connected to ribbed stiffener.
The large span steel truss of the utility model is since web has been respectively adopted in vertically and horizontally in profound bar to upper profound bar under
Yu Shangxuan bar bottom plate is respectively welded under on profound bar web in the H-type section (H profile steel) of setting, the upper and lower ends of web member, sufficiently benefit
With the structural advantage of horizontal H profile steel, the bearing capacity of profound bar is substantially increased down, the mechanical property of profound bar performs to by under
Maximum also eliminates plane outer support rod piece, and web member is located in the slot of H profile steel, accurate positioning, will not deflection and positioning,
Keep entire steel truss structure specification firm, so as to be made into the truss of large span and floor carrying people and object can be installed additional.On
Peg is set on profound bar top flange, can be good at realizing the connection with floor, and make full use of the compressive strength of upper floor,
So as to realize large span and realizing in the system makes exhibitions exhibition room etc. using function.Compared to traditional round tube greatly across
Truss is spent, the utility model structure is lighter and handier, and bearing capacity is bigger.In addition, the top surface of upper profound bar is plane, convenient for being laid with floor,
Convenient and quick construction.The utility model structural strength is high and simple and reliable, is easy to construction and installation, and cost is lower, economical and efficient, tool
Have wide practical use.

Fig. 2 is the schematic diagram that the utility model is looked up；
Fig. 3 is the utility model local nodes schematic diagram；
Fig. 4 is the scheme of installation using the large-span steel truss floor system of the utility model building.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model.
Profound bar 1, horizontal H-type are cut on large-span steel truss as shown in Figure 1, Figure 2, Figure 3 shows, including upright H-type section
Under face profound bar 2, upper and lower ends be respectively welded Yu Shangxuan bar bottom plate and under spaced set on profound bar web vertical round steel pipe
Web member 3 is symmetrically in the diagonal brace round steel pipe web member 4 being diagonally welded between adjacent two vertical round steel pipe web members；The upper profound bar 1
Length be greater than under profound bar 2 length, entire large span steel truss shape is trapezoidal.Under in the groove of profound 2 web lower part of bar
It is welded with ribbed stiffener 5 with Xia Xuan bar intersection positioned at vertical round steel pipe web member 3, with the intensity of profound bar under raising.Upper profound bar web
1a in being vertically arranged, under profound bar web 2a in horizontally disposed, welded in the slot of the lower end insertion H profile steel of vertical round steel pipe web member 3
Under on profound bar web 2a, upper end is welded in the base plate plane of profound bar.
As shown in figure 4, large-span steel truss floor system is constructed using the utility model, it can be by the utility model
Steel truss is fabricated to the trapezoidal truss of shape, profound pole length under upper profound pole length is greater than.Upper profound 1 both ends of bar are installed on bearing
On component 6, horizontal secondary beam 7 is installed between profound bar on two neighboring large span steel truss, is sequentially laid with finished product building on secondary beam
Plate 8.Beams of concrete, concrete column, concrete bracket, girder steel, steel column, any in steel corbel can be used in the supporting member 6
A kind of structural elements.Finished product floor can be prefabricated board, plank etc..
