Description
Technical field
The present invention relates to a kind of construction method of steel construction, the turn sliding in place method of especially a kind of Steel Truss Beam.
Background technique
Building Atrium Structure typically refers to the courtyard space of building interior, and maximum feature forms building interior
" exterior space " is that a kind of peculiar form be not only isolated but also merged with exterior space is built in architectural design.Surrounding structure is mixed
When Xtah Crude Clay structure, Atrium Structure can reduce beam size using steel structure girder, mitigate self weight, and two parts construction needs week of first constructing
Concrete structure is enclosed to construct again the part of steel construction.When surrounding concrete structure size is excessive, crane needs outside building
Side lifts Zhongting steel structure girder, there are the crane radius of gyration is big during this, steel structure girder constructional difficulties, can not accurate positioning,
The problems such as wasting manpower and material resources.
Summary of the invention
The object of the present invention is to provide the construction methods that a kind of Steel Truss Beam turns over sliding in place, to solve Zhongting steel construction
There are the crane radius of gyration is big when beam is installed, steel structure girder constructional difficulties, can not accurate positioning, the technology of wasting manpower and material resources asks
Topic.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of Steel Truss Beam turns over the construction method of sliding in place, and the Steel Truss Beam includes waiting pacifying at the Zhongting of building
Longitudinal steel truss of dress, longitudinal steel truss are completed structure from surrounding and are completed in structure to Zhongting in place, and knot is around completed
The junction that structure is completed in structure and Zhongting is equipped with first structure column, and it includes longitudinal steel truss to be installed that structure, which is completed, in the Zhongting
Connect on the first structure crossbeam and the second structural column connected between second structural column of frame, first structure column and the second structural column
The absolute altitude of the second structural beams connect, the second structural beams is higher than first structure crossbeam,
The construction method includes turn step, sliding step and the step in place that Steel Truss Beam is sequentially completed,
Steps are as follows for the turn:
Step 1 is completed in structure around and is laid with platform for lining, by the segment of longitudinal steel truss on platform for lining
One whole beam is pieced together using prone position, the top boom of longitudinal direction steel truss and lower boom fall and set in platform for lining when split is completed
On；
Step 2, is respectively set two the first door frames at two end positions of longitudinal steel truss, and the first door frame is stood
Column is fixed with platform for lining, is set on the crossbeam of the first door frame there are two lifting lug, hangs with a jack on each lifting lug, and respectively the
One jack and the second jack, with respect to the first jack at Zhongting, the top boom of longitudinal steel truss is located at first and falls the second jack
The lower section of chain, the first jack and the second jack are each attached on the top boom of longitudinal steel truss；
Step 3 is lifted top boom by constantly loosening the first jack and straining at the second jack until longitudinal steel truss
Frame is pulled to standing position, and longitudinal steel truss is equal to towards movement at Zhongting in whole process, and lower boom falls set in platform for lining always
On；
Step 4, installation truss overturning-preventing support, removes the first door frame；
Steps are as follows for the sliding:
Step 5, along first structure crossbeam direction, the first sliding rail beam is installed between two parties on first structure crossbeam,
First sliding rail beam is concordant with the absolute altitude that structure is completed in surrounding, one end of the first sliding rail beam and first structure column
It is detachably connected, the detachable spreading of the other end has the second sliding rail beam above the second structural column, second sliding
The other end of track girder and the side of the second structural beams are detachably connected；
Step 6, the mounting slip vehicle in the first sliding rail beam；
Step 7, is respectively set two the second door frames at two end positions of longitudinal steel truss, the second door frame across
Surrounding is completed at structure and Zhongting, and the column of the second door frame is fixed with platform for lining and the first sliding rail beam respectively, and second
It is set on the crossbeam of door frame there are two lifting lug, hangs with a jack, respectively third jack and the 4th jack on each lifting lug, the 4th
For jack with respect to third jack at Zhongting, the sliding vehicle of alignment lower section, the top boom of longitudinal steel truss is located at third jack
Lower section, third jack and the 4th jack are each attached on the top boom of longitudinal steel truss；
Longitudinal steel truss is completed from surrounding by constantly loosening third jack and straining at the 4th jack for step 8
Structure moves at Zhongting；
The top boom of longitudinal steel truss is transferred to sliding on vehicle and connecting with sliding vehicle, then removes second by step 9
Door frame；
Step 10 is slid forward in the first sliding rail beam until the second sliding rail beam using jack traction sliding vehicle
On；
It is described that steps are as follows in place:
Step 11, is respectively set two third door frames at two end positions of longitudinal steel truss, and third door frame is horizontal
Across the second structural beams and the first sliding rail beam, the column of third door frame respectively with the second structural beams and the first sliding rail
Beam is fixed, and the crossbeam of third door frame is equipped with a lifting lug, hangs with the 5th jack on lifting lug, the top boom of longitudinal steel truss is located at
The lower section of 5th jack；
Step 12 tenses the 5th jack, longitudinal steel truss is risen, and removes sliding vehicle and the second sliding rail beam；
Step 13: loosening the 5th jack, longitudinal steel truss is transferred, top boom is in place in advance on the second structural column
On mounted support, then its support is connected；
Step 14 removes third door frame and the first sliding rail beam.
The platform for lining is floor.
Second door frame is to install to obtain again by translation after the first door frame is removed.
First door frame, the second door frame or third door frame are equipped with support, and the support is skewed horizontal load bar and/or cable
Wind rope.
