Description
Technical field
The utility model belongs to the realm of building construction, is specifically related to door shape lifting appliance for a kind of building operations.
Background technology
Existing high pier construction, generally with over-form construction, over-form construction refers to tripod over-form construction technique, this kind of template bottom propped up into tripod with hack lever and supported, but the template weight of existing over-form construction is large, is inconvenient to transport, concrete placement layer by layer thickness is large, be not easy vibration compacting, its dress mould and form removal trouble, reduced operating efficiency and safety not high in addition.And form construction technology, embedded steel tube (being referred to as support bar) in works concrete, utilizes jack and hoisting frame that whole working load of sliding formwork are transferred on support bar exactly.After concrete reaches some strength, by self hydraulic lifting system by whole device along sliding on support bar, after Template Location, continue again to build concrete continuous a kind of job practices of circulation.Adopt slding form operation, can overcome the above-mentioned deficiency of over-form construction.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and door shape lifting appliance for a kind of building operations is provided, simple in structure, reasonable in design, can reduce the input to equipment such as delivery pump, tower cranes for implementing slding form operation, alleviate the weight of equipment.And concrete is worked continuously, there is no constuction joint, workmanship is reliable, and construction is fast, increases work efficiency, and has guaranteed construction safety, very practical.
The technical scheme that the utility model adopts is: door shape lifting appliance for a kind of building operations, comprise spaced two vertical support columns, described vertical support column is telescopic sleeve structure, between two vertical support columns, be provided with crossbeam, described crossbeam is positioned at vertical support column middle part, vertically support column top is provided with top board, on described top board, be provided with hopper, described hopper is connected on top board by steel cable and pulley, between top board and vertical support column, be provided with stiffening girder, vertically support column lower end is provided with base, the relative bilateral symmetry of described base is provided with installing plate, on described installing plate, be evenly provided with screwed hole, installing plate bottom is provided with rubber pad.
As preferably, described vertical support column adopts D159 steel pipe to make, and vertically on support column, is provided with locking device, and described top board and crossbeam adopt No. 12 channel-section steels to make.
As preferably, top board and crossbeam removably connect by U-bolt and vertical support column respectively, and described rubber pad adopts polyurethane rubber to make, and position corresponding with screwed hole on rubber pad has through hole.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, use the utility model, coordinate slip form frame, can carry out slding form operation, reduce the input to equipment such as delivery pump, tower cranes.A set of sliding mode system only weighs 12 tons, is 1/2 left and right of turning over mould weight.Concrete placement layer by layer thickness is 30cm only, easy vibration compacting, and concrete is worked continuously under normal circumstances, there is no constuction joint, and workmanship is reliable.Aspect progress, need only climbing forms at every turn, continuous circulation operation, has saved the operation of dress mould and form removal, and construction speed is fast, and can complete 4～6 meters every day, is the more than 4 times of over-form construction progress, shortened the duration, reduced engineering cost.Secure context, personnel carry out construction operation on the external mold die body sealing and scratch diskette, and falling from high altitude risk is minimum, and construction safety is secure.The relative bilateral symmetry of base is provided with installing plate, on installing plate, be evenly provided with screwed hole, facilitate installing/dismounting of the present utility model, installing plate bottom is provided with rubber pad, make installation of the present utility model more firm closely, and the effect with damping, has extended service life of equipment, there is good practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, vertical support column; 2, top board; 3, crossbeam; 4, stiffening girder; 5, base; 6, pulley; 7, hopper; 8, installing plate; 9, rubber pad.
The specific embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, door shape lifting appliance for a kind of building operations, comprise spaced two vertical support columns 1, described vertical support column 1 is telescopic sleeve structure, between two vertical support columns 1, be provided with crossbeam 3, described crossbeam 3 is positioned at vertical support column 1 middle part, vertically support column 1 top is provided with top board 2, on described top board 2, be provided with hopper 7, described hopper 7 is connected on top board 2 by steel cable and pulley 6, between top board 2 and vertical support column 1, be provided with stiffening girder 4, described stiffening girder 4 is obliquely installed, and has strengthened stability of the present utility model.Vertically support column 1 lower end is provided with base 5, the relative bilateral symmetry of described base 5 is provided with installing plate 8, on described installing plate 8, be evenly provided with screwed hole, facilitate installing/dismounting of the present utility model, installing plate 8 bottoms are provided with rubber pad 9, make installation of the present utility model more firm closely, and have the effect of damping, extend service life of equipment, there is good practicality.
In the present embodiment, as preferably, described vertical support column 1 adopts D159 steel pipe to make, and vertically on support column 1, is provided with locking device, and described top board 2 and crossbeam 3 adopt No. 12 channel-section steels to make.
In the present embodiment, as preferably, top board 2 and crossbeam 3 removably connect by U-bolt and vertical support column 1 respectively, facilitate transportation of the present utility model, installation and removal, and contracture while not affecting sliding pier shaft.Described rubber pad 9 adopts polyurethane rubber to make, and intensity is high, and abrasion resistance is good, long service life.Position corresponding with screwed hole on rubber pad 9 has through hole.
The utility model is the hoisting mechanism of sliding formwork die body, and when sliding pier shaft, the utility model is located on long fringe truss, and while building bent cap, design, on minor face truss, is loaded onto the utility model but assemble duration fringe truss and minor face truss on die body ground simultaneously.When bent cap is built, first the utility model of long fringe truss is removed, avoided superaltitude operation that the utility model is installed.
