Abstract
The invention relates to an assembly type jig frame for a longspan pipe truss roof girder. According to the structure, a support pillar is welded on a steel floor; upright posts are respectively welded on the steel floor which is positioned on two sides of the support pillar; inclined struts are respectively arranged on the outer sides of two upright posts; a lower chord positioning baffle plate is welded on the top surface of the support pillar; and upper chord positioning baffle plates are welded on the inner sides of the upright posts. By the assembly type jig frame, the overall assembly of the pipe truss roof girder is carried out on the spot ground, the pipe truss roof girder is hoisted and mounted by using a vertical type normal assembly method, so that the overall geometric dimensionings (including length, chord length, chord height, straightness, perpendicularity and the like) of pipe truss components are controlled; and because of the assembly on the ground, the working efficiency is greatly improved, the expenses of large-scale machines are saved, and the safety risks during the hoisting are also reduced relative to other mounting methods.
Description
Technical field
The present invention relates to a kind of spelling bearing tool of pipe truss roof girder, specifically a kind of spelling moulding bed of large-span pipe truss roof girder.
Background technology
The cross section is that the pipe truss roof girder of del is an arch space truss structure, laterally is two to stride, and span has more than 100 meter, and setting height(from bottom) is at three, 40 meters.During installation, the welding of the two ends of roof girder is supported on the steel column support of triangular-section; Middle span is supported on the capital of concrete support column.Because single article span of pipe truss roof girder is big, weight is big, form of structure is special, so generally be to make factory's sectional making, be transported to the scene then, assembling in the high-altitude.This mounting means makes the bulk of pipe truss roof girder wayward, and the security risk when installing is bigger.
Summary of the invention
The object of the invention just provides a kind of spelling moulding bed of large-span pipe truss roof girder, to overcome many unfavorable factors that large-span pipe truss roof girder high-altitude spelling exists, simplifies the installation of pipe truss roof girder, improves installation accuracy.
The present invention is achieved in that a kind of spelling moulding bed of large-span pipe truss roof girder, comprising:
Steel floor as the basis;
Be welded on the support pier on the said steel floor, its height is identical with the springing height of the pipe truss roof girder at place, this moulding bed arch camber of living in Support Position, and its width is identical with the cross section Breadth Maximum of the pipe truss roof girder at place, this moulding bed arch camber of living in Support Position;
Be positioned at said support pier both sides, be welded on the column on the said steel floor;
Be arranged on the diagonal brace that the said column outside is used to reinforce said column, the upper end of said diagonal brace is welded on the outside of said column, and the lower end of said diagonal brace is welded on the said steel floor;
Be welded on the said support pier, be used for the lower chord tube of pipe truss roof girder is carried out the lower edge positioning baffle of lateral register; And
Be welded on the positioning baffle that winds up that said column is inboard, be used for the pipe that winds up of pipe truss roof girder is carried out the support location.
Spacing between two said columns is exceeded with two on the pipe truss roof girder that can hold place, the arch camber of living in Support Position pipes that wind up.
The invention provides and a kind ofly can carry out the spelling moulding bed that spelling is used large-span pipe truss roof girder.Adopt this spelling moulding bed, can manage the spelling of the whole of truss roof girder or office's section on the ground, and then the lifting lift-off; Install and fix; Can guarantee to manage the dimensional accuracy of trussmember so to greatest extent, and spelling can be increased work efficiency greatly also on the ground, save the big machinery expense; Other mounting methods have also reduced the security risk when lifting relatively.
Description of drawings
Fig. 1 is a spelling moulding bed of the present invention and the structural representation of the pipe truss roof girder that is supported.
Among the figure: 1, steel floor, 2, support pier, 3, column, 4, diagonal brace, 5, roof girder, 6, the lower edge positioning baffle, 7, positioning baffle winds up.
The specific embodiment
As shown in Figure 1, pipe truss roof girder is the space truss structure that the cross section is del, is made up of the some web members that wind up pipe (bar) and be connected between the upper and lower string pipe of a lower chord tube (bar), two equal heights.Spelling moulding bed of the present invention is exactly a ground arch camber bracing frame during as pipe truss roof girder spelling and custom-designed.
The bottom of spelling moulding bed of the present invention is the steel floor 1 as brace foundation; On steel floor 1, be welded with support pier 2; The height of support pier 2 is identical with the springing height of the pipe truss roof girder at place, this moulding bed arch camber of living in Support Position, and the cross section Breadth Maximum of the width of support pier 2 and the pipe truss roof girder at place, this moulding bed arch camber of living in Support Position is consistent.Spacing being welded with respectively on the steel floor of support pier 2 both sides between column 3, two root posts 3 is exceeded with two on the pipe truss roof girder that can hold place, the arch camber of living in Support Position pipes that wind up.Be respectively arranged with diagonal brace 4 in the outside of two columns 3, the upper end of diagonal brace 4 is welded on the outside of column 3, and the lower end of diagonal brace 4 is welded on the steel floor 1, and the effect of diagonal brace 4 is that column 3 plays reinforcement effect.
For preventing to manage the skew of truss roof girder on this spelling moulding bed, at two parallel lower edge positioning baffles 6 of end face welding of support pier 2, so that the lower chord tube on the pipe truss roof girder is carried out lateral register; In the inboard of two columns 3, be welded with the positioning baffle 7 that winds up respectively, respectively two pipes that wind up on the pipe truss roof girder are carried out the support location.
Form the spelling moulding bed of some height series of gradual change thus by the requirement of roof girder springing height; In one line; Be arranged on the ground of roof girder erecting bed; Supporting to carrying out whole counterpart spelling by the assembly of making the plurality of sections pipe truss roof girder that factory makes and transport, will manage after truss roof girder assembly is welded into a roof girder integral body, lifting is in place.
Spelling moulding bed of the present invention is behind the whole spelling of the ground of erecting bed enterprising administration-management truss roof girder; Can use vertical upright method of hull section construction that pipe truss roof girder is lifted and installs; The whole geometry size (comprising length, chord length, action, straightness accuracy, verticality etc.) of not only managing trussmember is controlled, and ground spelling improved operating efficiency greatly, has saved the big machinery expense; Other mounting methods have also reduced the security risk when lifting relatively.
