Description
Technical field
The present invention relates to technical field of building construction, more particularly to large span, the big scale of construction, multi storied factory building installation steel roof joist
Reinforced concrete frame structure Factory Building construction technology.
Background technology
At present, with the continuous development of social process of industrialization, the land resource needed for industrial premises is built is more in short supply,
This requires that the construction of Factory Building must develop towards multilamellar.Multi storied industrial factory building typically adopts reinforced concrete frame structure, steel
The form that structure colored steel roof combines.Compared with steel-structure factory building, with floor space it is little, large and medium-sized machinery can be born
The characteristics of equipment heavy load.
When the industrial premises roofing of Multistory reinforced conceete frame Structure carries out steel beam lifting, generally using large-tonnage
Truck crane lifts steel roof joist along Factory Building surrounding, or the less truck crane of tonnage is hoisted to into flooring according to girder steel weight enters again
The lifting of row steel roof joist.
In view of above-mentioned hanging method, if being lifted from large-tonnage truck crane, is then first had to Factory Building surrounding
Truck crane track route enters professional etiquette and carries out necessary process to road foundation so as to meet the requirement of bearing capacity, while also
Pay high One-Shift Costs；If carrying out steel beam lifting operation from truck crane is hoisted to into flooring, when there is flooring
Concrete cast-in-place slab Lack of support is so that when bearing truck crane and carrying out lifting operation, this needs to take necessity to floor concrete again
Reinforcement measure, this undoubtedly also can development that is very uneconomical and can affecting other subsequent handlings.
The content of the invention
For the construction difficult problem of Multistory reinforced conceete frame Structure factory building roof hoisting steel beam, the present invention proposes a kind of structure
Make simple, processing and fabricating it is easy, from heavy and light, small volume, convenient lifting construction equipment of walking.
The present invention includes being provided with the base of U-shaped framework, and at least four groups universal wheels are connected below base, solid on base
Determine load-bearing vertical rod, in the upper end of vertical rod electric block is connected.
The present invention makes and draws materials extensive, cheap, can gather materials on the spot assembling at roofing scene, with traditional lifting mode phase
Than, the input of big-and-middle-sized mechanical one-shift expense had both effectively been reduced, the expenditure of other measure costs can be saved again, while the duration also obtains
Effective guarantee is arrived.The base of U-shaped framework is particularly provided with, movement of the whole loop wheel machine on roofing can be significantly facilitated.
The loop wheel machine both can conveniently lift roofing span centre longitudinal direction girder steel, roofing end bay longitudinal direction girder steel, and bundled purlin can be lifted again, can
Man-hour is greatly shortened, labor intensity is reduced.
Further, the base for being provided with U-shaped framework of the present invention includes two mobile jibs being parallel to each other, in two masters
First connecting rod, second connecting rod and third connecting rod are respectively welded in the plane of bar and between two mobile jibs, three connecting rods are mutually put down
OK, three connecting rods and two mobile jibs are respectively perpendicular arrangement, and second connecting rod is arranged between first connecting rod and third connecting rod, and described
The U-shaped plane cavity that stretch into can roofing column is surrounded between one connecting rod and two mobile jibs；The universal wheel is connected to
The lower section of two mobile jibs.This is simple and reasonable for structure, and the center of gravity for making whole loop wheel machine is maintained at middle part, improves during handling
The stability of loop wheel machine.
The load-bearing vertical rod includes a main vertical rod and two auxiliary vertical rods, and the lower end of the main vertical rod is welded on first connecting rod
Middle part, the lower end of two auxiliary vertical rods is respectively welded on second connecting rod, the main vertical rod and two auxiliary vertical rods be parallel to each other and
Perpendicular to the plane that two mobile jibs are located, between the main vertical rod and two auxiliary vertical rods some connecting rods are welded；In main vertical rod
Upper end overhanging type weld a cantilever steel girder, the electric block is connected on the cantilever steel girder.
In order to strengthen two auxiliary vertical rods, or even the support strength of whole load-bearing vertical rod, the present invention is also in the auxiliary vertical rod per root
Two differing heights on weld with one end of bracing piece respectively, the other end of each bracing piece is respectively welded at corresponding mobile jib
On.
Further, also some connecting rods can also be welded between two bracing pieces of same auxiliary vertical rod welding.
In order to further improve bonding strength, the present invention welds the first little Lian also between first connecting rod and second connecting rod
Bar, welds the second small rod between second connecting rod and third connecting rod.
It is another object of the present invention to propose application of the above loop wheel machine in the steel beam lifting of roofing span centre longitudinal direction, i.e. user
Method.
Comprise the following steps：
1）Assemble to form the unpowered walking loop wheel machine of the steel roof joist construction in roofing；
2）By universal wheel by the loop wheel machine horizontal sliding in the roofing column lower section of roofing span centre to be installed longitudinal direction girder steel, and make
The roofing column is located in the base of the U-shaped framework of the loop wheel machine, rotates the base of the loop wheel machine, makes base with the room
The axial direction of the vertical concrete beam above the column of face is in 45 ± 20 ° of angle；
3）The base of the loop wheel machine is paved by cushion block, makes universal wheel leave flooring plane；
4）Steel roof joist to be lifted is held on into the base top of the loop wheel machine；
5）Fastening is fixed at the middle part of the roofing span centre longitudinal direction girder steel to be lifted unload first；
6）Fastening positioned at the middle part of roofing span centre longitudinal direction girder steel to be lifted is unloaded into first to dock with the suspension hook of electric block,
In roofing span centre longitudinal direction, the two ends of girder steel each connect a bearing of body in the air control pull rope；
7）Start electric block, and by pulling two bearing of body in the air to control pull rope in roofing, make roofing span centre longitudinal direction
Standing to the vertical promotion along the roofing column to the pre-embedded bolt top beyond the roofing column upper top for girder steel, keeps
A piece bearing of body in the air controls the pulling force of pull rope, and another bearing of body in the air is controlled into the free end of pull rope from the roofing column
Top vertical concrete beam top pass through after, then make roofing span centre longitudinal direction steel by drawing the bearing of body in the air and controlling pull rope
Beam rotates in the horizontal plane, until roofing span centre longitudinal direction girder steel is perpendicular with vertical concrete beam；
8）Two bearing of body in the air control pull ropes of loopback and electric block, by the bolt hole in the middle part of the girder steel of roofing span centre longitudinal direction
