The specific embodiment
below in conjunction with accompanying drawing, the present invention is described in further detail, but not as any limitation of the invention.
a kind of method that large operation platform is installed between two high buildings, as shown in Figures 1 to 4, the method is by one section of Bailey bracket of assembly in the operation layer of A high building, then by operating personnel, with crowbar, to B high building direction, prize Bailey bracket, the Bailey bracket weight on floor is unsettled Bailey bracket 1.5 times time; In Bailey bracket rear end, connect again one section of Bailey bracket as counterweight, and then prize Bailey bracket to B high building direction, make Bailey bracket weight on floor be greater than all the time 1.5 times of unsettled Bailey bracket weight, until Bailey bracket front end rides over B high building operation layer, then remove the Bailey bracket as counterweight; With same method, between A high building operation layer and B high building operation layer, set up two Bailey brackets, then between two Bailey brackets, set up i iron, form operating platform after finally laying template on i iron.Described Bailey bracket front end is connected with the bottle gouard moved by hands at B high building operation layer top with the bottle gouard moved by hands at A high building operation layer top respectively; When operating personnel prize Bailey bracket with crowbar to B high building direction, can be by the weight of the bottle gouard moved by hands at A high building operation layer top and the bottle gouard moved by hands balance Bailey bracket overhanging portion at B high building operation layer top.Described one section of Bailey bracket bottom with assembly is provided with one group of steel pipe vertical with Bailey bracket moving direction, to reduce the frictional resistance of Bailey bracket and operation layer bottom surface.The bottle gouard moved by hands at described A high building operation layer top is mentioned Bailey bracket front end, and the bottle gouard moved by hands at B high building operation layer top slowly pulls forward Bailey bracket to alleviate operating personnel, to prize the labour intensity of Bailey bracket; Bailey bracket is in prizing process, and the bottle gouard moved by hands at the bottle gouard moved by hands at A high building operation layer top and B high building operation layer top is all the time in tension.
what by preceding method, form installs the device of large operation platform between two high buildings, as shown in Figure 2, comprises the A bottle gouard moved by hands 1 that is arranged on A high building operation layer top and the B bottle gouard moved by hands 2 that is arranged on B high building operation layer top; A bottle gouard moved by hands 1 is connected with Bailey bracket 7 tops through wire rope, and B bottle gouard moved by hands 2 is connected with Bailey bracket 7 front ends through wire rope.Bailey bracket 7 bottoms are provided with one group of steel pipe 5, steel pipe 5 and vertical setting of Bailey bracket 7 length directions.Bailey bracket 7 rear ends are provided with for prizing the crowbar 6 of Bailey bracket 7.
Embodiment
during concrete enforcement, as shown in Figures 1 to 5, implement according to the following steps
step 1, as shown in Figure 1, interior by one section of Bailey bracket 7 of assembly at A high building operation layer 3, between Bailey bracket 7 bottoms and the ground of A high building operation layer 3, place the steel pipe 5 of one group of φ 48mm, steel pipe 5 is perpendicular to the length direction of Bailey bracket 7.The bottle gouard moved by hands 1 at A high building operation layer top and the bottle gouard moved by hands 2 at B high building operation layer top are installed respectively on the upper floor plated construction beam of A high building operation layer 3 and B high building operation layer 4, and the bottle gouard moved by hands 1 at A high building operation layer top is sling in the interior one section of Bailey bracket with assembly of A high building operation layer 3.The bottle gouard moved by hands 2 at B high building operation layer top is through tying up at Bailey bracket 7 front ends with wire rope.
step 2, as shown in Figure 2, pulls the bottle gouard moved by hands 1 at A high building operation layer top, and Bailey bracket body 7 is upwards promoted, and pulls the bottle gouard moved by hands 2 at B high building operation layer top simultaneously, makes to tie up wire rope at Bailey bracket 7 front ends all the time in tension.Then operating personnel use crowbar to prize Bailey bracket 7 rear ends, make Bailey bracket 7 move forward front end and stretch out A high building operation layer 3 edges in vacant state.
step 3, as shown in Figure 3, when the length of stretching out A high building operation layer 3 edges when Bailey bracket 7 is Bailey bracket 7 length approximately 2/5, the bottle gouard moved by hands 2 that stops prizing Bailey bracket 7 rear ends and pull B high building operation layer top, in Bailey bracket 7 rear ends, install again a joint Bailey bracket additional as counterweight, installed the rear bottle gouard moved by hands 2 that continues to prize Bailey bracket 7 rear ends and pull B high building operation layer top additional.Every hauling-out is installed a joint Bailey bracket additional again once joint Bailey bracket, makes Bailey bracket weight on floor be greater than all the time 1.5 times of unsettled Bailey bracket weight, guarantees that Bailey bracket can weightlessness not fall.
step 4, as shown in Figure 4, when the front end of Bailey bracket 7 rides over behind the edge of B high building operation layer 4 smoothly, adjusts lap length, and the length that Bailey bracket 7 rides over two high buildings is not less than 1 meter.Finally unclamp bottle gouard moved by hands, remove the steel pipe 5 of counterweight Bailey bracket and Bailey bracket bottom.
step 5, as shown in Figure 5, installs a Bailey bracket 7 again by step 1-4, then between two Bailey brackets 7, sets up i iron 8, finally on i iron 7, lays the installation that completes large operation platform after template 9.
aforementioned Bailey bracket 7 adopts assembly type steel bridge on highway trussed construction.By top-bottom chord, montant and brace, be welded.One end of top-bottom chord is cloudy head, and the other end is positive head.Negative and positive head has pin hole.During connection, the sun head of a joint is inserted in the cloudy head of another joint, aim at pinhole, plug pin.It is simple, quick, economical that the present invention constructs, and can meet the feasibility of setting up operating platform when large-scale component cannot be used tower crane to enter floor, and without personnel's work high above the ground, guarantee safety.
