Abstract
The invention discloses a construction method for clustered type assembling arch ribs. The construction method adopts a clustered type assembling method. The construction method comprises the following steps of laterally dividing arch ribs into a plurality of arch rib bunches arranged in parallel for step-by-step construction; firstly assembling each of the arch rib bunches in the longitudinal direction one by one; and after assembling each of the arch rib bunches is completed, performing lateral permanent connection, namely completing the construction of the arch ribs. According to the construction method disclosed by the invention, according to the span size of the arch ribs, the arch ribs are divided into the arch rib bunches arranged in parallel for step-by-step construction, and the divided arch rib bunches are light in weight, so that the required bearing capacity of a steel structure arch frame is low, the using of basal materials and equipment is reduced, the construction cost is reduced, the construction cycle is reduced, and potential safety hazards to foundations of peripheral environment are avoided.
Description
Technical field
The present invention relates to the assembled technical field of arch rib, in particular to a kind of construction method of cluster type assembly arch rib.
Background technology
Existing stiff skeleton method is made by cable crane and temporary towers drag-line, first sets up steel pipe stiff skeleton 8, profit
With the bearing capacity of the steel pipe stiff skeleton 8 of erection, then irrigate high-strength concrete in steel pipe, to further enhance its carrying
Ability, then by the use of steel tube concrete soil skeleton as supporter, finally hangs mould construction and forms armored concrete arch rib 9.
However, the armored concrete arch rib being supported using support support or stiff skeleton, its steel pipe stiff skeleton 8 is permanent
Property structure it is not possible to recycling, lead to the cost of arch rib high.Particularly, when building large span arch rib, to stiff skeleton
Requirement for bearing capacity is higher, and the basic material of needs and equipment are more, further increases cost expense, extends construction period,
Also there is potential safety hazard to surrounding enviroment ground.
Content of the invention
Present invention aim to providing a kind of construction party of the assembled arch rib of cluster type safe, that operating expenses is low
Method.
For achieving the above object, a kind of construction method of the cluster type assembly arch rib designed by the present invention, walks including following
Rapid:
1) the transverse width size according to arch rib, arch rib is transversely divided into the arch rib bundle substep of several laid out in parallel apply
Work；
2) assembly is longitudinally docked section by section in first arch rib Shu Caiyong some sections rib-lifting section edge, closes up formation entirety, completes
The construction of first arch rib bundle；
3) assembling construction of second arch rib bundle, repeat step 2 are carried out in first laterally adjacent empty place of arch rib bundle)
Assembled second arch rib bundle；
4) carry out the assembling construction of next arch rib bundle in second laterally adjacent empty place of arch rib bundle, often assembly completes
One arch rib bundle, just installs next arch rib bundle in its laterally adjacent empty place, until assembly completes all arch rib bundles；
5) finally using transverse prestress cable wire, each arch rib bundle is connected, completes the construction of arch rib.
Further, in step 2) in, in described first arch rib bundle, some section rib-lifting sections are along longitudinally docking spelling section by section
Dress method is: along longitudinally two spaced apart steel construction bow members of erection, the horizontal spacing between described two steel construction bow members
Not less than the transverse width of first arch rib bundle, carry out first arch rib bundle using two described steel construction bow members as supporting body
Assembly, first arch rib bundle is arranged in the interval between two described steel construction bow members, and keeps lateral connection.
Further, the horizontal spacing between two steel construction bow members is the transverse width of first arch rib bundle.
Further, in step 3) in, described first laterally adjacent room of arch rib bundle is: laterally moved out one of
The room that steel construction bow member reserves, the transverse width in this room is defined by the transverse width of second arch rib bundle, second arch rib
Bundle is arranged in the room between first arch rib bundle and laterally moved out steel construction bow member.
Further, in described step 4) in, often assembly completes an arch rib bundle just in its laterally adjacent empty place peace
The next arch rib bundle of dress particularly as follows: often assembly complete an arch rib bundle just laterally moved out one of steel construction bow member left room
The room installed as next arch rib bundle.
Further, in step 2) in, in described first arch rib bundle, some section rib-lifting sections are along longitudinally docking spelling section by section
Dress order is: often section rib-lifting section docks assembly from arch springing successively to vault.
Further, each described steel construction bow member is formed along longitudinal being detachably connected by some section box beams.
Further, it is respectively adopted splicing board component between each side of box beam described in two adjacent sections to connect.
Further, described splicing board component includes being arranged on the first splice plate inside two adjacent sections box beam, is arranged on
The second splice plate outside two adjacent sections box beam and bolt assembly, described first splice plate and the second splice plate are by adjacent two
The side wall clamping of section box beam, and the gap between two adjacent sections box beam is adjusted according to the curvature of corresponding arch rib, finally by bolt
Assembly is locked.
Further, described arch rib is reinforced concrete structure.
Compared with prior art, the present invention has the advantage that
First, the present invention by applying arch rib according to the arch rib bundle substep that arch rib span size is divided into several laid out in parallel
Work, the arch rib Shu Chongliang after decomposition is little, and the bearing capacity of required steel construction bow member diminishes, and decreases basic material and equipment uses,
Thus reducing cost expense, shorten construction period, it is to avoid potential safety hazard is caused to the ground of surrounding enviroment.
Second, the steel construction bow member of the present invention is detachably connected using splicing board component, it is possible to use a upper arch rib bundle
Laterally moved out steel construction bow member as next arch rib bundle steel construction bow member so that steel construction bow member repeat profit
With greatling save operating expenses.
Third, the construction method of the present invention has universality to all kinds of arch rib assembly and simple, construction is convenient, tool
There are very strong operability and practicality.
