Abstract
The invention discloses a separate hoisting method of a wide-span steel roof truss. The method comprises the following steps: firstly, separating the steel roof truss into a left steel roof truss segment, a middle steel roof truss segment and a right steel roof truss segment; secondly, using a temporary auxiliary fixing rod to ensure an angle and a position relation between a lower chord and a web member of the left steel roof truss segment and the right steel roof truss segment; thirdly, using the temporary auxiliary fixing rod to ensure the angle and the position relation between the lower chord and the web member of the middle steel roof truss segment; fourthly, hoisting the left steel roof truss segment and the right steel roof truss segment in place by an erecting mechanism and firmly fixing; fifthly, hoisting the middle steel roof truss segment in place by the erecting mechanism; sixthly, connecting upper chords of the left steel roof truss segment and the right steel roof truss segment with the upper chord of the middle steel roof truss segment by upper chord splicing angle steel and an upper chord splicing gusset plate of the steel roof truss; and seventhly, connecting the lower chords of the left steel roof truss segment and the right steel roof truss segment with the lower chord of the middle steel roof truss segment by lower chord splicing angle steel and a lower chord splicing gusset plate of the steel roof truss, and removing or remaining the temporary auxiliary fixing rod.
Description
Technical field
The invention belongs to a kind of building structure.
Background technology
In new construction, the lifting of superstructure is the elevating capacity that machinery is installed according to the building site, is assembled into bigger installation unit on the ground, to reduce the workload of work high above the ground, if singly refer to steel roof truss, adopts the mode of integral hoisting usually.But in transformation, because the interior equipment installation and operation that constructed the factory buildings, construction lifting space is limited, causes very difficulty of wide span steel roof frame integral hoisting.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of wide span steel roof frame split hanging method is provided, during with, the installation machinery that can not enter be complementary elevating capacity comparatively narrow that overcomes that prior art exists in working face, the deficiency of wide span steel roof frame lifting difficulty.
In order to solve the problems of the technologies described above, the present invention has taked following technical scheme: it may further comprise the steps: first, the steel roof truss of design is divided into steel roof truss left side section 1, steel roof truss stage casing 2 and 3 three sections making of the right section of steel roof truss, the second, guarantee about steel roof trusses that with interim auxiliary fixed beam 14 angle, the position between the section web member 12 concerns about section lower chord 6 and steel roof truss; The 3rd, guarantee that with interim auxiliary fixed beam 14 angle, position between steel roof truss stage casing lower chord 7 and the steel roof truss stage casing web member 13 concern; The 4th, with steel roof truss left side section 1 and steel roof truss right section 3 hoisted in position and fixed; The 5th, with steel roof truss stage casing 2 hoisted in position; The 6th, adopt equal strength welding connecting method, is connected section upper chord 4 and steel roof truss stage casing upper chord 5 about steel roof truss with steel roof truss splicing angle steel 8 and the steel roof truss splicing gusset plate 10 that winds up that winds up; The 7th, adopt equal strength welding connecting method, be connected section lower chord 6 and steel roof truss stage casing lower chord 7 about steel roof truss with steel roof truss lower edge splicing angle steel 9 with steel roof truss lower edge splicing gusset plate 11.
In first step, steel roof truss stage casing 2 slightly is longer than other two sections.
In the 4th, the 5th step, adopt and machinery is installed respectively with steel roof truss left side section 1, the right section 3 of steel roof truss and steel roof truss stage casing 2 hoisted in position.
In the 6th, the 7th step, adopt equal strength welding connecting method, is connected section upper chord 4 and steel roof truss stage casing upper chord 5 about steel roof truss with steel roof truss splicing angle steel 8 and the steel roof truss splicing gusset plate 10 that winds up that winds up; Be connected section lower chord 6 and steel roof truss stage casing lower chord 7 about steel roof truss with steel roof truss lower edge splicing angle steel 9 with steel roof truss lower edge splicing gusset plate 11.
After finishing the 7th step, can remove interim auxiliary fixed beam 14, can not remove yet and kept.
In such scheme, wide span steel roof frame adopted segmental hoisting is in place, the method for assembly unit, the construction emphasis is to produce the inside and outside distortion in plane when avoiding the roof truss lifting, takes strengthening measure before lifting.
Compare with method in the past, wide span steel roof frame manufacturing in the industrial premises of the installation machinery that the present invention is comparatively narrow for working face, can not enter the elevating capacity that is complementary, lifting provide easy, effective processing method, this method node processing is simple, construction install convenience.
