Abstract

The utility model relates to a sliding framework platform for a large-column gird large-area net frame structure. The sliding framework platform comprises towers, a suspended span frame and an overhanging frame, wherein at least two columns of towers are included, two longitudinal towers are connected through transverse frames; the bottoms and the top parts of the transverse towers are connected with the suspended span frame, and the top parts of the outer sides of the transverse towers are connected with the overhanging frame; steel pipes at the bottom ends of the transverse towers are sleeved on pulleys, the axis of the steel pipes is coincided with that of the pulleys; and the pulleys are placed on guide rails, cross sleepers are laid below the guide rails, and the guide rails and the cross sleepers are fixed through spot welding. Pulleys are installed on the bottom surface of the sliding framework platform, and the sliding framework platform for construction can be realized through the moving of the pulleys. Compared with the traditional scaffold, the quantity of erected scaffolds and the disassembly and assembly are reduced, and at the same time, the problems of overlarge flexibility value and large displacement deflection of net frames planned to be erected caused by overlarge overall settling amount of construction brackets are avoided, therefore the sliding framework platform can be widely applied to the installation and construction of large-column gird large-area net frame structures.

Technical field

The utility model relates to the operation platform that a kind of steel mesh frame is installed, particularly a kind of huge pillar net large tracts of land space truss structure balladeur train platform.

Background technology

Usually job practicess such as full hall frame high altitude bulk method, lift-on/lift-off system, whole lift method, rack sliding method are adopted in the rack construction, but for huge pillar net large tracts of land space truss structure, because the scaffold area that need set up is excessive, or the lifting appliance tonnage is excessive, tend to produce common quality defects such as excessive such as support bulk settling amount, that the rack deflection value is excessive, offset deviation is big, and the above several method is owing to the time of setting up of construction supporting facility is longer, often cause the duration longer, thereby cause construction costs higher.

The utility model content

The purpose of this utility model provides a kind of huge pillar net large tracts of land space truss structure balladeur train platform, solve the technical problem that causes the rack distortion in traditional rack construction easily; And the problem of large tracts of land rack is set up in solution in the short duration.

For achieving the above object, the utility model adopts following technical scheme:

A kind of huge pillar net large tracts of land space truss structure balladeur train platform comprises support body, and it is characterized in that: described support body is by pylon, the suspended span frame and the frame of encorbelmenting are formed, pylon is at least two row, connects by crossbearer between two vertical pylons, and the bottom all is connected with the suspended span frame with the top between two lateral towers, the pylon outside top connects the frame of encorbelmenting, the steel pipe socket of pylon bottom on pulley, its axis and pulley dead in line, described pulley is placed on the guide rail, be laid with sleeper under the described guide rail, both fix in spot welding.

Described balladeur train platform is at least one group, connects by connector between every group of balladeur train platform.

The bottom surface of described suspended span frame is equipped with bridging.

Be welded to connect between described guide rail and the continued access guide rail.

The bottom surface of the part of described crossbearer between two pulleys is connected with the adjustable seats that is used for fixing the balladeur train platform.

The height of described balladeur train platform is following 2.5 meters of the lower chord of intending setting up rack.

Compared with prior art the utlity model has following characteristics and beneficial effect: (1) quality is controlled easily.Rack is installed on the handling frame of similar full hall scaffold and operates, and handling frame intensity, rigidity, stability are all better, and each span rack forms a stable structure unit, and error is controlled easily; Generally take from the centre can to reduce accumulated error to the job practices of both sides slippage.(2) shorten the construction period and save construction cost.Only need set up the sliding platform of a unit truss, rack is installed one, and the slippage handling frame carries out the installation of next unit truss more forward, can provide a plurality of work planes to construct simultaneously.The save operation frame is set up the time, accelerates the rack set-up time.(3) effectively utilize the place.Placing of material is evacuated relatively, and material loading is convenient, has effectively utilized the construction plant.

(4) the employed pulley of sliding platform, sliding rail are reusable, can not cause harmful effect to environment.

The utility model has overcome traditional rack and has set up platform and tend to produce common quality defects such as support bulk settling amount is excessive, the rack deflection value is excessive, offset deviation is big, and because the time of setting up of construction supporting facility is longer, often cause the duration longer, thereby cause the higher shortcoming of construction costs, solved the technical problem of efficiently setting up the large tracts of land rack in the short period of time fast.

The utility model can be widely used in the erection construction of huge pillar apart from the large tracts of land rack.
