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 tubular truss roof girder, specifically a kind of spelling moulding bed of Node In Large-span Pipe Truss roof girder.
Background technology
Cross section is the tubular truss roof girder of del is arch space truss structure, be laterally two across, span has more than 100 meter, and setting height(from bottom) is at three, 40 meters.During installation, the two ends welding of roof girder is supported on the steel column support of triangular-section; Middle span is supported on the capital of concrete support post.Because single product span of tubular truss roof girder is large, weight large, version is special, so be generally at making factory sectional making, be then transported to scene, assemble in high-altitude.This mounting means makes the bulk of tubular truss roof girder wayward, and install time security risk larger.
Summary of the invention
Object of the present invention is just to provide a kind of spelling moulding bed of Node In Large-span Pipe Truss roof girder, to overcome many unfavorable factors that Node In Large-span Pipe Truss roof girder high-altitude spelling exists, simplifies the installation of tubular truss roof girder, improves installation accuracy.
The present invention is achieved in that a kind of spelling moulding bed of Node In Large-span Pipe Truss roof girder, comprising:
Based on steel floor;
Be welded on the support pier on described steel floor, its height is identical with the springing height of the tubular truss roof girder at arch camber Support Position place residing for this moulding bed, and its width is identical with the cross section Breadth Maximum of the tubular truss roof girder at arch camber Support Position place residing for this moulding bed;
Be positioned at described support pier both sides, the column be welded on described steel floor;
Be arranged on for reinforcing the diagonal brace of described column outside described column, the upper end of described diagonal brace is welded on the outside of described column, and the lower end of described diagonal brace is welded on described steel floor;
Be welded on described support pier, for carrying out the lower edge positioning baffle of lateral register to the lower chord tube of tubular truss roof girder; And
Be welded on inside described column, for carrying out the positioning baffle that winds up of support location to the pipe that winds up of tubular truss roof girder.
Spacing between two described columns is limited with two pipes that wind up that can hold on the tubular truss roof girder at residing arch camber Support Position place.
The invention provides a kind of spelling moulding bed that can carry out spelling to Node In Large-span Pipe Truss roof girder.Adopt this spelling moulding bed, the entirety of tubular truss roof girder or the spelling of office's section can be carried out on the ground, and then lifting lift-off, install fixing, can ensure the dimensional accuracy of tubular truss component so to greatest extent, and spelling also can be increased work efficiency greatly on the ground, save big machinery expense, other installation methods, also reduce security risk during lifting relatively.
Accompanying drawing explanation
Fig. 1 is spelling moulding bed of the present invention and the structural representation of the tubular truss roof girder supported.
In figure: 1, steel floor, 2, support pier, 3, column, 4, diagonal brace, 5, roof girder, 6, lower edge positioning baffle, 7, wind up positioning baffle.
Detailed description of the invention
As shown in Figure 1, the space truss structure of tubular truss roof girder to be cross section be del, is made up of a lower chord tube (bar), two mutually level pipe (bar) and some web members be connected between upper and lower string pipe of winding up.Spelling moulding bed of the present invention is exactly custom-designed as ground arch camber bracing frame during tubular truss roof girder spelling.
The bottom of spelling moulding bed of the present invention is the steel floor 1 as brace foundation, steel floor 1 is welded with support pier 2, the height of support pier 2 is identical with the springing height of the tubular truss roof girder at arch camber Support Position place residing for this moulding bed, and the width of support pier 2 is consistent with the cross section Breadth Maximum of the tubular truss roof girder at arch camber Support Position place residing for this moulding bed.The steel floor of support pier 2 both sides is welded with column 3 respectively, and the spacing between two root posts 3 is limited with two pipes that wind up that can hold on the tubular truss roof girder at residing arch camber Support Position place.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 steel floor 1, and the effect of diagonal brace 4 is that column 3 plays reinforcement effect.
For preventing the skew of tubular truss roof girder on this spelling moulding bed, weld two parallel lower edge positioning baffles 6, to carry out lateral register to the lower chord tube on tubular truss roof girder at the end face of support pier 2; In the inner side of two columns 3, be welded with the positioning baffle 7 that winds up respectively, to carry out support location to two on tubular truss roof girder the pipe that winds up respectively.
Formed thus some height by the requirement of roof girder springing height one of gradual change serial spelling moulding bed, in one line, be arranged on the ground of roof girder erecting bed, with to by making factory makes and the assembly of the some sections of tubular truss roof girders transported carry out overall counterpart spelling support, after tubular truss roof girder components welding is become a roof girder entirety, lifting is in place.
Spelling moulding bed of the present invention is after the overall spelling of the ground of erecting bed enterprising line pipe truss roof girder, vertical upright method of hull section construction can be used to lift tubular truss roof girder and install, not only the whole geometry size (comprising length, chord length, action, linearity, perpendicularity etc.) of tubular truss component is controlled, and ground spelling substantially increases operating efficiency, save big machinery expense, other installation methods, also reduce security risk during lifting relatively.
