Description
Technical field
The invention belongs to installation technology of steel structure field, more particularly to large-span steel truss high-altitude sliding in place side
Method.
Background technology
With flourishing for China's steel cause, application of the steel construction in civil buildings is more and more extensive, in order to obtain
The playground of indoor large-area is obtained, large-span steel truss roof structure is in all kinds of gymnasium, large stadium roofworks
In application it is increasing.Industry is constructed in all kinds of gymnasium, large stadium 36m above large-span steel truss roof structure
When, because truss span is too big, single truss structure weight is too heavy（Generally higher than 40t）, generally use 800t above crawler crane or
More than 1000t truck cranes carry out single truss structure lifting, in place.The conventional hoisting construction process method of industry is generally present such as at present
Lower deficiency：
（1）Due to large-scale hoisting machinery dead weight reason, large-scale hoisting machinery needs to lay at the construction field (site) higher before marching into the arena
Grade accommodation road and larger station truck position place, as job site can not provide large-scale hoisting machinery march into the arena road and station car
Position, then it can not carry out single Pin large-span steels truss integral hoisting construction.
（2）Large-scale hoisting machinery also needs to carry out the assembling of equipment, counterweight debugging at the scene after marching into the arena, and is needed after the completion of construction
The work such as equipment Removal are carried out, equipment prepares and teardown phase is required for arranging lifting to coordinate in addition, and required preparation is taken
With high, the preparation time is longer.
（3）When lifting single Pin large-span trusses using large-scale hoisting machinery, space after the lifting of large span list truss structure is in place
Stability is very poor, it is easy to causes single truss structure Spatial Instability slump accident, can not ensure safe construction.
（4）Large-scale hoisting machinery lease is very difficult, and equipment enters the difficulty that appears on the scene, and equipment enters costly, the lease expenses that appears on the scene
Height, Construction Cost are high.
（5）Large stadium job site is typically respectively provided with tower crane, but its elevating capacity is usually more than 5t, therefore can not profit
Large-scale truss integral hoisting is carried out with the existing tower crane in scene to construct.
（6）After often lifting the large-scale truss of a Pin, crane is required for shifting, and carries out next truss structure lifting construction and prepares.Often
Secondary displacement is required for place cleaning again, props up vertical crane again, is at least delayed duration half a day, causes MU efficiency low,
Mechanical one-shift is caused to waste.
The content of the invention
The technical problems to be solved by the invention are：Large-span steel truss high-altitude sliding in place method is provided, solved
Because of place or other construction reasons, it is impossible to enable large-scale hoisting machinery, and the situation of tower crane elevating capacity deficiency on construction ground
Under, carry out the high-altitude installation of large-span steel truss.
In order to solve the above-mentioned technical problem, inventor draws technical scheme by research and summary, including with
Lower step：

A2, layer Steel Structure truss both ends longitudinal axis capital position lay two groove steel rails；
A3, simultaneously coating butter will be cleaned up in groove steel rail, several slide devices are set in every groove steel rail；
A4, the end of every groove steel rail respectively installation one hoist engine；
Step 2：Truss assembling
B1, in interim the first truss structure of assembly platform over-assemble structure；
B2, the first truss structure structure is jacked into 150mm by jack on interim assembly platform, in the first truss structure structure
Four suspension column position cushioning several slide devices；
B3, decline the first truss structure structure, the first truss structure structure is seated on slide device；
Dilatory first truss structure structure, the first truss structure structure pass through simultaneously in the case of unified command for B4, two hoist engines
Hoist engine, slide device and groove steel rail sliding in place；
B5, the first truss structure structure are drawn safely to design and installation position, again by jack by the first truss structure structure
150mm is jacked, removes the slide device of four suspension column position cushionings of the first truss structure structure, declines the first truss structure structure, makes
First truss structure structure is seated on space truss bearing and welded after correction；
Step 3：Follow-up truss installa-tion
C1, follow-up large-span truss are installed successively, and truss is welded after correction, pacified after space truss bearing is in place in time
It is identical with step 2 to fill flow；
Preferably, slide device one shares 4 in the A3, is solid forging metal block.
Preferably, the both sides of every groove steel rail set several to slide side shield in the A2.
Preferably, the both sides of groove steel rail are marked every 100cm with red paint in the A2.
Preferably, two hoist engine heaves must check every 100cm and once draw the depth of parallelism and timely in the B4
Adjustment.
Compared with prior art, the present invention can obtain following technique effect：
(1) using the large-span steel truss high-altitude sliding in place method of the present invention, can effectively solve because assembling, lifting place
The situation of installation requirements can not be met.
(2) using the large-span steel truss high-altitude sliding in place method of the present invention, it is not necessary to using Large-scale Hoisting machine
Tool, the small-sized tower crane in scene is made full use of, has greatly saved engineering cost.
(3) using the large-span steel truss high-altitude sliding in place method of the present invention, truss is slid and installed, reduced
Difficulty of construction, increase the security of construction.
