Abstract
The utility model provides a steel column positioning rack based on a reverse-building method. The steel column positioning rack is mounted on the ground surrounding the top of a steel pipe column which is based on the reverse-building method and is put in a post hole previously. The positioning rack comprises four corner posts symmetrically arranged at the corners of a rectangle; cantilevers are fixed to the sides, facing the steel pipe column, of the corner posts hierarchically and alternately; a shaft bracket and an adjustable pulley are connected to the inner ends of the cantilevers; the adjustable pulley is in rolling connection with the surface of the steel pipe column; connecting rods are fixed hierarchically between the adjacent corner posts; four connecting rods of each layer are corresponding to the cantilevers, respectively, and are located on the same horizontal plane together with the cantilevers; and a hawser cable connected with the ground is arranged on the sides, far away from the steel pipe column, of the corner posts. The steel column positioning rack based on the reverse-building method can be used for solving the technical problem that the verticality of the steel pipe column cannot be adjusted in the hoisting process of a steel steel reinforcement cage when the steel reinforcement cage is used for positioning the steel pipe column in the traditional one-column and one post construction process based on the reverse-building method.
Description
Technical field
The utility model relates to a kind of auxiliary installation device of building unit, particularly the locating rack of steel pipe column use in place during a kind of contrary sequence method.
Background technology
When high-building construction, current increasing employing " inverse method one-column one-pile " constructs to control the duration." contrary sequence method " is exactly first along building basement axis or construct on every side diaphragm wall or other supporting and protection structure, intermediate support stake and post are built or laid in the relevant position of interior of building simultaneously, bearing superstructure as construction period before the base plate back cover conducts oneself with dignity and Supporting of construction load, then the construct beam slab floor structure of ground one deck, as the very large support of diaphragm wall rigidity, downward earth excavation and build each layer underground structure successively subsequently is until the base plate back cover.Simultaneously, because the floor structure of ground one deck is finished, for Superstructure Construction has been created condition, successively carry out the construction of superstructure so can make progress simultaneously.So ground is upper and lower constructs simultaneously, until engineering finishes." one on a post " is exactly the foundation structure form of only having a pile under post.As seen, the verticality of construction steel tubing string becomes the key component of whole construction technology.When adopting at present " inverse method one-column one-pile " construction, adopt reinforcing cage that steel pipe column is positioned more.Because reinforcing cage needs hoisted in position, but can't adjust its verticality in the hoisting process.
The utility model content
The purpose of this utility model provides a kind of contrary sequence method steel column locating rack, solve when reinforcing cage positions steel pipe column in tradition " inverse method one-column one-pile " construction technology, reinforcing cage can't carry out the technical problem that verticality is adjusted to steel pipe column in hoisting process.
For achieving the above object, the utility model adopts following technical scheme:
A kind of contrary sequence method steel column locating rack, be installed in and put on the ground of contrary sequence method steel pipe column top, hole periphery, described locating rack comprises symmetrically arranged four corner posts in rectangular angle, described corner post is fixed with cantilever lever towards steel pipe column one side layering interval, the inner of described cantilever lever is connected with pedestal and adjustable pulley, described adjustable pulley is rolled with the surface of steel pipe column and is connected, layering is fixed with connecting rod between the adjacent corner post, four connecting rods of every layer and cantilever lever are corresponding and be on the same level respectively, and described corner post dorsad steel pipe column one side is provided with the cable wind rope that is connected with the earth.
Described connecting rod can be i iron, channel-section steel, steel pipe or H shaped steel.
The number of plies of described adjustable pulley and cantilever lever setting is the 2-5 layer.
Described connecting rod all is that plug-in type connects with cantilever lever and being connected of steel pipe column, and adjacent two connecting rods intersect in steel pipe column and are welded and fixed, and the outer wall that described cable wind rope passes steel pipe column is fixedly connected with the outer end of the cantilever lever of the superiors.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The utility model Assembling, easy and simple to handle, can have enough to meet the need use, and not be subjected to the steel pipe column size restrictions, and in hoisting process, can adjust steel pipe column, guarantee that steel pipe column is concentric with pile foundation.
When the utility model can be widely used in erection of steel pipe column to the adjustment of steel pipe column verticality.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Reference numeral: 1-corner post, 2-adjustable pulley, 3-cantilever lever, 4-cable wind rope, 5-steel pipe column, 6-connecting rod, 7-distance pole, 8-pedestal.
The specific embodiment
A kind of contrary sequence method steel column locating rack, be installed in and put on the ground of hole contrary sequence method steel pipe column 5 top peripheries, described locating rack comprises symmetrically arranged four corner posts 1 in rectangular angle, described corner post 1 is fixed with cantilever lever 3 towards steel pipe column 5 one side layering intervals, the inner of described cantilever lever 3 is connected with pedestal 8 and adjustable pulley 2, described adjustable pulley 2 is rolled with the surface of steel pipe column 5 and is connected, layering is fixed with connecting rod 6 between the adjacent corner post 1, four connecting rods 6 of every layer and cantilever lever 3 are corresponding and be on the same level respectively, and described corner post 1 dorsad steel pipe column 5 one sides is provided with the cable wind rope 4 that is connected with the earth.
Described corner post 1 is common steel tube or scaffolding steel pipe.Described connecting rod 6 is i iron, channel-section steel, steel pipe or H shaped steel.Described adjustable pulley 2 is the 2-5 layer with the number of plies that cantilever lever 3 arranges.Described connecting rod 6 is connected with being connected of steel pipe column 5 with cantilever lever all be that plug-in type connects, and adjacent two connecting rods intersect in steel pipe column and are welded and fixed, and the outer wall that described cable wind rope 4 passes steel pipe column is fixedly connected with the outer end of the cantilever lever 3 of the superiors.
In the present embodiment, connecting rod 6 is set to 3 layers with cantilever lever 3.
Mounting method of the present utility model:
Locating rack is installed on the ground, is set the cross position line in hole and locating rack upper end that steel pipe column 5 is transferred with steel wire respectively, determine the position of adjustable pulley according to the cross position line.Connecting rod 6 is three layers with cantilever lever 3 in the present embodiment, and every layer of totally four adjustable pulley 2 are adjusted its verticality by adjustable pulley.
For guaranteeing that steel pipe column reaches the verticality requirement of designing requirement, the verticality that hangs in the installation process can only be read by surveying through big instrument, so must guarantee the required precision of latitude instrument, operating personnel must be conscientious careful.In place and by after adjusting verticality and reaching requirement when erection of steel pipe column, subsequent handling all must avoid making steel pipe column to be shifted and collision-deformed accident.
