Abstract
The invention discloses a method for assembling fixed ends of a scaffold of a large-volume triangular variable-section tubular truss structure. The method is characterized in that: a concrete base is poured on the ground; a large tubular truss, of which two ends are provided with triangular sections, is horizontally assembled above the concrete base; after finishing the assembly, the whole is pulled by a hoisting mechanism, and a rod piece between the two sections is assembled above a scaffold supporting system at a certain angle; and after finishing the assembly, tail sections of the fixed end sections on two sides are dismounted, and are mounted to the start sections of the next section of assembled structural member. The method has the advantages that: under the condition that pre-assembly cannot be performed on the construction site, the assembly precision is guaranteed as much as possible; furthermore, the two fixed end sections are positioned, and the rod piece between the two sections is used as a pivot, so that the manufacturing material of the scaffold is saved.
Description
Technical field
The present invention relates to a kind of big volume triangularity cross section pipe trussed construction moulding bed fixed end assembly unit method.
Background technology
Present especially big triangularity cross section steel building has been increasing to have obtained application; And mostly existing job practices is ground falsework bulk technique, and the reliable supporting system is set, the loose mail lifting; Install in the high-altitude; Progressively accomplish the method for building, claim for eot, and also work high above the ground is abnormally dangerous and efficient is very low.Also useful in recent years ground moulding bed assembly unit triangle varying cross-section duct truss carries out integral installation, and is regular little but present big triangle varying cross-section duct truss ground moulding bed assembly unit exists, the characteristics of moulding bed quantity and the many cases of specification.The engineering urgent for the duration and the place is limited, the big segmented assembly in ground, the method for integral lifting exists some insoluble problems, as in limited construction plant, being difficult to arrange assembly unit moulding bed various and that kind is various.Therefore demand developing novel big volume triangularity cross section pipe trussed construction moulding bed fixed end assembly unit method urgently and existing problem is installed to solve present big triangularity cross section steel building.
Summary of the invention
The objective of the invention is to solve big triangularity cross section steel building installation employing loose mail lifting in the prior art, existing the problems referred to above are installed in the high-altitude, and pipe trussed construction moulding bed fixed end assembly unit method in a kind of big volume triangularity cross section is provided.The present invention designs big volume triangular-section pipe trussed construction moulding bed fixed end assembly unit method, it is characterized in that: build the concrete basis on ground, crouch above it and piece together triangular-section, large-scale pipe truss two ends.After assembly unit finishes, rise with lifting appliance and to pull and be positioned at the moulding bed support system top rod member between two cross sections of assembly unit again by certain angle.After assembly unit finishes the concluding paragraph in fixed end cross section, both sides is removed the The initial segment of getting off to be mounted to next section assembling members.It is characterized in that: concrete basis, described ground is a triangle concrete bar, and its maximal side is greater than the variable cross-section triangle maximal side that needs assembly unit.It is characterized in that: described moulding bed support system be the assembled support system of i iron comprising the Chain block hitch point, the jack strong point.Advantage of the present invention be restricted at the construction field (site) can't preframed situation under, must guarantee splicing accuracy as far as possible, because locate in fixed end cross section, two ends, middle rod member assembly unit can rely on it save the moulding bed manufacturing materials as the strong point simultaneously.
Description of drawings
Fig. 1 is a triangle tube truss typical section form sketch map.
Fig. 2 is a H shaped steel support system sketch map.
Fig. 3 is pipe trussed construction assembly unit schematic flow sheet.
Fig. 4 removes the local reinforcement sketch map for the triangular-section.
The specific embodiment
Build the concrete basis on ground among the figure, crouch above it and piece together triangular-section, large-scale pipe truss two ends.After assembly unit finishes, rise with lifting appliance and to pull and be positioned at the moulding bed support system top rod member between two cross sections of assembly unit again by certain angle.After assembly unit finishes the concluding paragraph in fixed end cross section, both sides is removed the The initial segment of getting off to be mounted to next section assembling members.It is characterized in that: concrete basis, described ground is a triangle concrete bar, and its maximal side is greater than the variable cross-section triangle maximal side that needs assembly unit.It is characterized in that: described moulding bed support system be the assembled support system of i iron comprising the Chain block hitch point, the jack strong point.
Among Fig. 1,2,3,4 above triangle concrete basis 1 assembly unit all size pipe diameter be 1 meter triangle typical section member 2.After assembly unit finishes; Pull 2 of triangular-section members to certain angle and utilize in the H shaped steel support system of every main chord 3 belows Chain block 4 to proofread and correct the back and fix with crane with diagonal brace with jack 5, whether consistent with the coordinate figure of apparatus measures both sides each end points of typical section with theoretical value.After treating triangle tube truss cross section, two ends positioned, assembly unit horizon bar 6 and brace 7 after integral assembling finishes, are removed the triangular-section 8 of an end successively, and use the end that is put in next Pin pipe truss, and the like finish until assembly unit.Such method can not have the whole preframed job site of condition to guarantee the precision of assembly unit.Before removing, the triangular-section root of dismounting need be done local reinforcement 9 to guarantee safety.Can avoid a large amount of moulding beds of producing owing to erratic behavior that variable cross-section causes in the whole process, thereby the typical moulding bed system simultaneously among Fig. 1 can effectively be practiced thrift moulding bed quantity and reached the purpose of having saved construction cost and having reduced the construction plant demand.Especially as far as the narrow and small engineering in construction plant, when having solved the place problem especially, also guaranteed this patent the precision of assembly unit.
