Abstract
The invention relates to a method for manually installing a steel beam at the top of a silo. The method is characterized in that a silo top steel beam is arranged on a slip form device in the beginning of slip form and is lifted to the top of the silo by using the sliding form device, before last concrete is poured into the wall of the silo, two pre-embedded steel slabs are embedded at two sides of a design installation site of the steel beam on the top surface of the silo, and two door-shaped hanging brackets straddle two ends of the steel beam and are firmly welded with the pre-embedded steel slabs arranged at two sides; and two chain hoists are respectively arranged on the two door-shaped hanging brackets arranged at two ends of the steel beam, two end sockets of the steel beam are respectively and firmly connected with the chain hoists arranged on the two door-shaped hanging brackets by using steel wire ropes, the two chain hoists are operated by a constructor to slowly lift the steel beam so that the steel beam is separated from a steel beam bracket arranged on the slip form device, then the steel beam bracket is dismantled, and finally the chain hoists are manually and slowly adjusted to place the steel beam in the structure position of the wall of a concrete storage. The method has the advantages that the construction cost is more greatly reduced, good economic benefit is obtained, simultaneously, manual operation is finer in comparison with mechanical operation, and the construction quality and safety are increased.
Description
Technical field
The invention belongs to the realm of building construction, when particularly relating to the wall slding form operation of silos storehouse, adopt the artificial method that storehouse-top steel girder is installed.
Background technology
The silos structure in present industrial construction field, the girder steel form is all adopted in roof girder design in top, storehouse, and conventional construction method utilizes large-scale crane that the girder steel lifting of making is pushed up to the storehouse for after silos storehouse wall has been constructed; Perhaps girder steel is promoted to storehouse top, and then utilizes large-scale crane that girder steel is hung oneself from sliding formwork equipment to be filled to roof construction position, storehouse by sliding formwork equipment.The silos structure is often higher, is example with the raw material silo of cement plant, and its storehouse heights of roofs surpasses 50m, and clear height also reaches more than the 40m between top, storehouse and bottom of the reservior.2 tons the girder steel of after the storehouse wall has been constructed, will weighing again winches to the 50m eminence, needs the crane of lifting capacity more than 150 tons, and cost of use is high, also is difficult for finding this kind equipment in remote districts, needs call in from the other places, delays the duration.Though the activity duration that a kind of method in back can reduce large-scale crane is reduced part crane cost of use, can't fundamentally eliminate the dependence to large-scale crane; Do not reduce how many costs yet; The crane operation amplitude is bigger simultaneously, and lifting personnel and commanding need highly to keep synchronously, and be careless slightly; Cause girder steel and sliding formwork equipment or storehouse wall to collide easily, bring danger to the constructor.
Summary of the invention
The object of the invention will overcome the above problems exactly; The method of top, a kind of artificial installation tube Kuku girder steel is provided, utilize artificial with storehouse-top steel girder by the sliding formwork equipment hoisting to structure position, need not be by large-scale crane; Be completely free of dependence to large-scale crane; Only need simple device can accomplish the installation of girder steel, greatly reduce construction cost, improved benefit by manual work; The amplitude of manually-operated simultaneously is less, is easy to control, and can not cause the collision of girder steel and sliding formwork equipment or storehouse wall, has reduced construction safety risk effectively.
Technical scheme of the present invention is achieved like this: the method for top, a kind of artificial installation tube Kuku girder steel; At the beginning promptly be placed in sliding formwork equipment at sliding formwork storehouse-top steel girder; Utilize sliding formwork equipment that it is promoted to the top, storehouse, be characterized in: along with finishing of storehouse wall construction, before Ku Bi builds last concrete; Each embedding two pre-embedded steel slab of the both sides of the design and installation position of girder steel on its end face; Adopt channel-section steel to make second mate's " door " font suspension bracket at the scene, " door " font ceiling height need be above about girder steel end face 1m, second mate's " door " font suspension bracket ride on the girder steel two ends and with the pre-embedded steel slab firm welding of both sides; On two " door " font suspension brackets on the girder steel two ends, a bottle gouard moved by hands is installed respectively; With wire rope with the two ends of girder steel respectively with two " door " font suspension bracket on bottle gouard moved by hands be connected firmly; Operating two bottle gouards moved by hands by the constructor slowly mentions girder steel; Make that the girder steel carriage is separated on itself and the sliding formwork equipment, remove the girder steel carriage then, artificially slowly regulate bottle gouard moved by hands again girder steel is put to the locations of structures of concrete storehouse wall; Dismountable after having lifted a Pin " door " font suspension bracket removes to install next Pin, until steel roof joist is all installed end.
The present invention has reduced construction cost significantly, has obtained good economic benefit, and manually-operated simultaneously is more meticulousr than machinery, and construction quality, safety all are improved.

Fig. 2 is the artificial girder steel device elevational schematic view of installing.
Among the figure: 1---sliding formwork equipment; 2---girder steel; 3---pre-embedded steel slab; 4---door-shaped hanging bracket; 5---bottle gouard moved by hands; 6---concrete storehouse wall; 7---wire rope.
The specific embodiment
Storehouse-top steel girder 2 promptly is placed on the sliding formwork equipment 1 at sliding formwork at the beginning; Utilize sliding formwork equipment 1 that it is promoted to the top, storehouse, when finishing, before storehouse wall 6 is built last concrete along with 6 constructions of storehouse wall; Each embedding two pre-embedded steel slab 3 of the both sides of the design and installation position of girder steel 2 on its end face; Simultaneously field by using 10# channel-section steel is made second mate's " door " font suspension bracket 4, door-shaped hanging bracket 4 highly need above about girder steel 2 end face 1m, door-shaped hanging bracket 4 ride to girder steel 2 and with pre-embedded steel slab 3 firm welding of both sides.For strengthening the stability of door-shaped hanging bracket 4, do the oblique connection of twice with 50 angle steel and support.Girder steel 2 two ends respectively are provided with a door-shaped hanging bracket 4, lay a 5t bottle gouard moved by hands 5 on each door-shaped hanging bracket 4.With wire rope 7 bottle gouard moved by hands 5 on girder steel 2 and the door-shaped hanging bracket 4 is connected firmly; Operating bottle gouard moved by hands 5 by the constructor slowly mentions girder steel 2; Make that the girder steel carriage is separated on itself and the sliding formwork equipment 1; Remove the girder steel carriage then, the locations of structures that bottle gouard moved by hands 5 is put girder steel on the wall 6 to the concrete storehouse is slowly regulated in manual work again.Dismountable door-shaped hanging bracket 4 is installed next Pin after having lifted a Pin, until steel roof joist is all installed end.
