Abstract
The utility model discloses a carrying pole device used for construction. The utility model has the key points that the carrying pole device at least comprises two girders arranged in parallel; the included angle R between the longitudinal center lines of the two adjacent girders is 5-10 degrees; and the lower end surface of one end of each of the girders is fixed with a lower beam, and the other end surface thereof is fixed with an upper beam. The carrying pole device has convenient processing and is easy for hoisting a beam slab, so as to well maintain hoisting equipment; in addition, the carrying pole device has simple structure and convenient use.
Description
Technical field
The utility model relates to a kind of construction equipment, especially relates to two suspension centre vertical-lift shoulder pole devices in a kind of bridge construction process.
Background technology
At present, in the bridge construction process of mountain area, bridge construction is subjected to the restriction of narrow landform easily, the installation of beam slab need be carried out vertical-lift, because beam slab length and heterogeneity, beam slab that can not each length is provided with a Hoisting System, will increase difficulty of construction and equipment cost greatly like this, and is both uneconomical also impracticable.And the lifting of traditional beam slab is directly to adopt lifting appliance to promote the fixing back of beam slab, when if beam slab is too short like this, lifting appliance will be subjected to the pulling force of an inclination, so both be not easy to the lifting of beam slab, simultaneously also can cause the lifting appliance bending, use the destruction that lifting appliance can be in various degree for a long time.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of construction shoulder pole device of realizing that fast, reliably beam slab is installed.
The technical solution of the utility model is as follows: the construction of design shoulder pole device, its main points are: comprise two girders at least, described girder is placed side by side, and the angle R between adjacent two girder longitudinal centre lines is 5 °～10 °, lower surface at described girder one end all is fixed with lower transverse beam, and other end upper surface all is fixed with top rail.
The deficiency that the utility model promotes at beam slab in traditional beam slab installation process creatively designs, when carrying out the beam slab lifting, determine the position of fulcrum by the Heave Here, then that lower transverse beam and beam slab is firm with the cable wire binding, at last hanging apparatus on the overhead traveling crane and top rail are bundled, thereby beam slab is sling, and section adjusts the position of the utility model and beam slab or hanging apparatus binding according to the length of beam slab in hoisting process, satisfies the requirement of vertical lifting; The utility model is designed to 5 °～10 ° with the angle R between adjacent two girder longitudinal centre lines, thereby makes more reasonable stress of the present utility model.
In order to be easy to realize and make fixing more reliable between girder and lower transverse beam and the top rail more, described girder and described lower transverse beam and top rail all are welded to connect, and described lower transverse beam is welded on the less end of adjacent girder distance, and described top rail is welded on the bigger end of adjacent girder distance.
As of the present utility model one preferred: described girder is two, and the longitudinal centre line extended line of these two girders intersects, and the angle R between these two girders is 7 °, is set to two girders in the rigidity that satisfies lifting, is easy to realize.
In order to satisfy rigidity requirement of the present utility model, described girder is welded side by side by three i iron, and the i iron of this girder adopts the 40b i iron, and with steel plate i iron is sealed, and the thickness of steel plate is 2cm; Described lower transverse beam and top rail are welded side by side by three i iron, and this i iron adopts the 32b i iron, and with steel plate i iron are sealed, and the thickness of steel plate is 1.6cm.
Beneficial effect: the utility model is easy to process, is easy to realize the lifting of beam slab, thereby well safeguards hanging device, and simple in structure, easy to use.
