Description
Technical Field
The invention relates to the field of atrium smallpox construction operation, in particular to a building method of an atrium floating bridge.
Background
With the rapid development of economy, large-scale consumption places such as shopping malls, hotels and the like are decorated very beautifully and complexly in order to attract customers, the most typical example is that a shopping mall atrium is designed into a hollow form, the design is already a basic design style of most large shopping malls at present, a ceiling or various decorations are often arranged on the ceiling of the atrium, and in later maintenance work, the maintenance work is difficult due to the fact that no standing surface exists; and many market atrium ground can reach more than 20 meters to smallpox height, if directly build vertical ascending scaffold frame then can greatly increased construction cost and time to occupy very big space, influence the market business.
The most common construction method at present is as follows: build the long bridge of a connection on the corridor of two opposite facades, transversely promote atrium department by the avris is whole again to the long bridge, and the workman stands and carries out maintenance work to the smallpox on the long bridge, and this kind of way has very big limitation, can only be used for atrium not have the condition of stand all around just can use, if there is the stand, can block the promotion process of long bridge. At present, shopping malls visiting various large cities find that more than half of the shopping malls have stand columns which are tightly attached to the hollow edge of the atrium, so that the long bridge of the building method cannot be pushed to the atrium.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the method for building the atrium floating bridge, which is not limited by the stand column, has high applicability and meets the requirement of atrium ceiling operation.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a building method of an atrium floating bridge comprises the following steps:
step one, respectively placing two bridging machines on two opposite corridors, and installing bridge seats on the bridging machines to form a firm frame;
step two, building a combined aluminum alloy frame along the bridge seat at the corridor until the building of the snake frame is completed;
rotating the bridging machine to enable the two groups of snake racks to float out and face each other;
step four, materials are conveyed to the inner cavity of the snake-shaped frame from the corridor, a combined plate bridge unit is assembled in the inner cavity of the snake-shaped frame, the plate bridge unit is pushed towards the drifting-out direction, after the space is vacated, the next plate bridge unit is continuously assembled, and the steps are repeated until the drifting-out length of the two groups of plate bridges meets the requirement of the butt joint length;
step five, pushing one group of the plate bridges to enable the rod piece on one group of the plate bridges to be in butt joint and buckling with the locking buckle on the other group of the plate bridges, and pre-tightening and assembling the two groups of the plate bridges;
and step six, the operator walks near the front end of the plate bridge, fastens the two groups of plate bridges by using the connecting piece, and completes the construction.
As an improvement of the above technical scheme, in the second step, the inner cavity of the snake rack is also paved with slide rails, and in the fourth step, the sheet bridge unit is pushed along the slide rails to the drifting direction.
As an improvement of the above technical solution, before or after the sixth step, the following steps are further performed: laying platform plates at the bottoms of the snake rack and the slab bridge, then installing protective guards on the left side and the right side of the slab bridge, and building a scaffold leading to the top of the atrium at the front end of the slab bridge.
As an improvement of the technical scheme, in the first step, the lower end of the bridge seat is provided with a supporting leg which can stretch up and down.
As an improvement of the technical scheme, the locking buckle is provided with a release handle for unlocking the locking buckle, and one end of the release handle is provided with a pull rope extending to the bridge seat.
As an improvement of the technical scheme, the sheet bridge is a combined aluminum alloy frame, and the weight of the sheet bridge is lighter than that of the snake rack.
The invention has the following beneficial effects:
the building method starts to build on two opposite corridors, the floating bridge is built by overhanging towards the atrium direction from the corridor, the floating bridge is extended in length and finally butted and fastened to form a complete bridge, so that the stand column is bypassed, the requirement of atrium ceiling operation is met, the applicability is improved, the side corridor does not need to be built and then pushed to a working surface, the limitation of the stand column is avoided, the floor area is reduced, and the building method is safe and reliable.
