Abstract
The invention discloses an inverted-V-shaped truss with the span larger than 100 m and a construction method of an inverted-V-shaped truss. and belongs to the technical field of building construction. The inverted-V-shaped truss comprises foundations, truss bodies arranged on the foundations, purlines and roof panels, and the purlines and the roof panels are arranged on the surface layers of the truss bodies. The truss bodies are of inverted-V-shaped structures, and pre-stress structures are symmetrically arranged on the two sides of the inverted-V-shaped structure respectively. The pre-stress structures comprise steel ropes used for tensioning, and the two ends of the steel ropes are arranged on the same sides of the truss bodies. One ends of the steel ropes are connected with the parts, close to the foundations, of the bottoms of the truss bodies, and the other ends of the steel ropes are connected with the parts close to the tops of the truss bodies. A plurality of steel supporting rods which are arranged at intervals are connected between the steel ropes and the side faces of the truss bodies. According to the characteristics of triangular stockpiling and through combination of the structural design of the prestress steel ropes, the dead load of the truss can be further reduced, material consumption is reduced, and therefore a large-span truss structure which is more economical and more applicable is achieved.

Technical field
The invention belongs to technical field of building construction, relate to a kind of trussed construction, herringbone truss and construction method thereof that a kind of span that particularly heavy grade trussed construction and prestressed cable are combined into is greater than 100 meters.
Background technology
Stock yard, power plant, mining stockyard etc. have the industrial and mining enterprises of airborne dust side effect, by the face of stricter environmental requirement, add a cover closed airborne dust under needing not stopping production condition.Because material storage space is huge, generally triangular in shape or trapezoidal windrow, often needs the roof structure designing large span.
But, when closing this delta stockpile field, general many employing arch-shaped space truss structures.Its arch-shaped space truss structure technology is ripe, and is extensively applied at home, but this space truss structure has the problems such as many, the on-the-spot amount of high-altitude operation of rod member are large, quality examination is difficult.It is generally acknowledged, when span is greater than 100m, the economic index of its space truss structure is not high.Meanwhile, the load that longspan structure is born comprises dead load, wind load, snow load, roofing live load, seismic load etc.Wherein the numerical values recited of wind load, snow load is except outside the Pass meteorological condition has with locality nature, also relevant with the shape of structure outline.Roof pitch, when certain limit, can take less wind load and snow load.When roof pitch is 30 degree, the impact of roofing wind load on agent structure can not be considered in theory.If when ensureing that roof pitch is 30 degree, expanding the span of trussed construction further, the physical dimension of truss will certainly be increased, not only cause its deadweight very heavy, and consume a large amount of steel.
Therefore, be necessary the feature for triangle windrow, propose the large-span truss structure be suitable for more economically.
Summary of the invention
In view of this, a kind of span is the object of the present invention is to provide to be greater than the herringbone truss of 100 meters, for the feature for triangle windrow, and in conjunction with prestressed cable structure design, truss deadweight can be reduced further, economize on material, to realize the large-span truss structure be suitable for more economically.Meanwhile, present invention also offers the construction method that a kind of span is greater than 100 meters of herringbone truss.
For achieving the above object, the present invention is achieved through the following technical solutions:
The invention provides the herringbone truss that a kind of span is greater than 100 meters, comprise basis, be located at truss body on basis and the purlin be located on this surface layer of truss and roof panel, described truss body is herringbone structure, its both sides are symmetrically arranged with prestressed structure respectively, described prestressed structure comprises the cable wire for stretch-draw, the two ends of described cable wire are all arranged on the homonymy of truss body, its one end is connected with the truss body bottom portion near basis, the other end is connected with near truss bodies top, several are connected with between this cable wire and truss body side, spaced apart steel strut.
Further, also comprise the storehouse lattice for storing material, described storehouse lattice are arranged at the below of truss bodies top, are provided with the pillar for sub-truss bodies top.
Span is greater than a construction method for 100 meters of herringbone truss, comprises the steps:
Step 1) construction basis;
Step 2) truss body is arranged on basis, form a herringbone structure system;
Step 3) cable wire is connected with truss body with steel strut;

Detailed description of the invention
Below with reference to accompanying drawing, the preferred embodiments of the present invention are described in detail; Should be appreciated that preferred embodiment only in order to the present invention is described, instead of in order to limit the scope of the invention.
Embodiment one:
As shown in Figure 1, the herringbone truss that a kind of span is greater than 100 meters, comprise basis 2, the purlin 5 being located at the truss body 1 on basis 2 and be located on this 1 surface layer of truss and roof panel 6, described truss body 1 is herringbone structure, its both sides are symmetrically arranged with prestressed structure respectively, described prestressed structure comprises the cable wire 3 for stretch-draw, the two ends of described cable wire 3 are all arranged on the homonymy of truss body 1, its one end fixed end is connected with bottom the truss body 1 on basis, the other end is connected with near truss body 1 top, several are connected with between this cable wire 3 and truss body 1 side, spaced apart steel strut 4, the quantity and spacing of described steel strut 4 can be determined according to the span of the stretching force size of cable wire 3 and truss body 1, and take the mode of 2 stretch-draw.Its construction method comprises following operating procedure:
Step 1) the good basis 2 of construction; Basis 2 is provided with the stone bolt be connected with truss body 1;
Step 2) truss body 1 is arranged on basis 2 by stone bolt, form a herringbone structure system; According to the span of structure, truss body 1 can be resolved into the sections of convenient transport and lifting.The length of every sections is 25m ~ 60m, adopts the splicing of high-strength bolt scene between sections and sections;
Step 3) cable wire 3 is connected with truss body 1 with steel strut 4, the two ends of described cable wire 3 are all arranged on the homonymy of truss body 1, its one end fixed end is connected with bottom the truss body 1 on basis, the other end is connected with near truss body 1 top, be connected with between this cable wire 3 and truss body 1 side several, spaced apart steel strut 4;
Step 4) mounting purlines 5; Purlin 5 and truss body 1 by being located by connecting, described in be located by connecting into bolt connect, welding, one or more combinations in riveted joint;
Step 5) cable wire 3 is carried out first time stretch-draw in the position near basis 2; And according to the amount of deflection of the 4th step, control the stretching force of cable wire 3; After cable wire 3 prestressed stretch-draw, the span of truss body 1 will diminish and the antiarch that truss body 1 is produced upwards is out of shape, and effectively reduces the deadweight amount of deflection of truss body 1 and purlin 5 generation and make component internal force obtain distribution again;
Step 6) roof panel 6 and other building fittings are installed, comprise the fixed equipment etc. of suspention on roof lighting board, truss body 1;
Step 7) cable wire 3 is carried out second time stretch-draw in the position near basis 2, and according to the amount of deflection that the 6th step produces, control the stretching force of cable wire 3; This time after stretch-draw cable wire 3, truss 1 can be made to produce a small amount of antiarch distortion upwards;
