Abstract
The invention discloses a method for hoisting a silo top steel beam by using a sliding form platform. The method comprises the following steps of: after sliding form equipment is assembled and before a silo wall is hoisted in a slip mode, finding positions corresponding to ends of the silo top steel beam on the sliding form platform, placing a steel beam bracket at each position, and welding with the sliding form equipment firmly; hoisting the steel beam on the brackets, and temporarily welding stably; erecting four sets of slip hoisting devices added at two ends of the steel beam on the sliding form platform, and uniformly controlling the slip hoisting devices by a hydraulic system in the sliding form equipment; and after the steel beam is well placed, performing construction according to normal sliding form construction programs, wherein after the construction of the silo wall is finished, the steel beam rises to the silo top together with the platform. By the method, the steel beam can be installed without a large crane, so that the construction cost is effectively reduced, the construction period is quickened, and the construction safety is improved.
Description
Technical field
The invention belongs to the realm of building construction, utilize the method and the device thereof of its sliding formwork equipment lifting storehouse-top steel girder when being specifically related to the wall slding form operation of a kind of silos storehouse.
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.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.The girder steel of 2t of after the storehouse wall has been constructed, will weighing again winches to the 50m eminence, needs the above crane of lifting capacity 150t, 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.Simultaneously in work progress, because the girder steel span is big, sling height is high, receives environment, climatic effect big, and construction technology and construction safety are all brought more acid test.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing the sliding formwork equipment lifting storehouse-top steel girder in the raw material silo slding form operation.
The objective of the invention is to realize like this: when the raw material silo bottom of the reservior part (about the about 9.000m of absolute altitude) of having constructed; Begin to get into storehouse wall slding form operation, assembled sliding formwork equipment after, on the sliding formwork platform, find out the pairing position of beam; Lay a girder steel carriage on each position; The carriage height calculates according to the girder steel height, can not touch mutually on carriage to guarantee steel girder erection with other parts of platform, carriage must with sliding formwork equipment firm welding.After the girder steel carriage installs, can girder steel be winched to and lay on the carriage firmly, and be welded on the carriage temporarily; On the sliding formwork platform, set up simultaneously the sliding device that rises of the extra increase quadruplet in both sides of girder steel; To rise device identical for the cunning of this device and sliding formwork equipment self; Form by hydraulic jack and the steel pipe that is embedded in the wall of storehouse; And by the unified control of the hydraulic system in the sliding formwork equipment, to improve the supporting capacity of sliding formwork platform; All are ready, can construct according to normal slding form operation program, and constructing when the storehouse wall finishes, and girder steel is also along with platform rises to the top, storehouse.
The device that utilizes the sliding formwork platform to promote girder steel provided by the present invention mainly contains girder steel carriage, jack and steel pipe, and the girder steel carriage can be accomplished by the channel-section steel field fabrication.Jack is employed consistent with sliding formwork equipment, and steel pipe is that φ 48 * 3.5mm common building scaffold is used steel pipe.
Job practices more in the past relatively; This method can be positioned over girder steel on the sliding formwork platform device wall bottom in the raw material Kuku; Along with platform rises to storehouse top,, need not the installation that large-scale crane can be accomplished girder steel because the sling height of girder steel is reduced to about 10m about by original about 50m; Effectively reduce construction cost, accelerate the duration and improve construction safety.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 utilizes sliding formwork equipment lifting girder steel floor map.
Fig. 2 utilizes sliding formwork equipment lifting girder steel elevational schematic view.
Among the figure: 1. sliding formwork equipment, 2. girder steel, 3. girder steel carriage, 4. jack, 5. φ 48 * 3.5mm steel pipe, 6. concrete storehouse wall.
The specific embodiment
Specify the method for sliding formwork equipment lifting storehouse-top steel girder of the present invention below in conjunction with accompanying drawing.
When raw material silo sliding formwork device assembles finishes, prepare storehouse wall slding form operation.Go up at sliding formwork equipment (1) earlier and find pairing position, girder steel (2) two ends by design drawing, on each corresponding position, lay a girder steel carriage (3), this carriage can utilize [50 channel-section steels making at the scene.Girder steel carriage (3) must be firm with sliding formwork equipment (1) welding, avoids sliding and rise in the process carriage displacement or tumble.When in place the finishing of girder steel carriage (3), can girder steel (2) be worked winching on the girder steel carriage (3), and firm welding.
Putting on the shelf at sliding formwork equipment, the newly-increased quadruplet in two ends of girder steel is sliding to rise device, and this device is made up of jack (4) and φ 48 * 3.5mm steel pipe (5), and to rise device identical with cunning on the sliding formwork equipment, and unification is by the HYDRAULIC CONTROL SYSTEM of sliding formwork equipment (1).Improve the bearing capacity of sliding formwork equipment.Steel pipe (5) is along with the lifting of sliding formwork will be imbedded in the storehouse wall concrete (6) piecemeal.
This girder steel lift method is successful implementation in the construction of a plurality of raw material silos, bigger saving construction cost, simplify construction sequence.Construction speed, quality all are improved.
