Abstract
The utility model discloses a positioner for a concrete filled steel tubular column reverse building method. The positioner comprises upper portion guide positioning elements, an upper portion elevation positioning ring, and a lower portion elevation positioning ring, wherein the upper portion elevation positioning ring is connected with the lower portion elevation positioning ring through supporting rods. The positioner for the concrete filled steel tubular column reverse building method has the advantages that a certain gap between a concrete filled steel tubular column and a foundation or the top of a cushion cap through the positioner body is achieved, and when concrete is poured, the pressure of the concrete and externally-wrapped concrete produced can be removed. Due to large space in each element of the positioner, the blocking problem of coarse particles of the concrete is effectively avoided. A cross intersection formed in the top of the positioner body is convenient to coincide with measure of a wellhead center when the positioner is installed. Due to the fact that setscrews are adopted in a bearing portion of the positioner, danger caused by welding operation at the bottom of the well is avoided.
Description
Technical field
The utility model relates to a kind of locator that is applied to the steel core concrete column contrary sequence method.
Background technology
At present, be positioned with the location technology of comparative maturity at the bottom of the post for steel pipe column when the reverse construction, but when running into encased structures, owing to need concrete perfusion in the steel pipe, traditional location technology (locator) can not be suitable for then.Subject matter is that traditional position location techniques has limited the normal pressure release of concrete in the casting process process, causes the concrete casting leakiness or can't inner perfusion directly form the external wrapping concrete structure.
The utility model content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, a kind of normal pressure release in concreting process to be provided, to build closely knit, as to realize the concrete outside steel pipe locator that is applied to the steel core concrete column contrary sequence method.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of locator that is applied to the steel core concrete column contrary sequence method, comprise upper guide to keeper, top absolute altitude locating ring, bottom absolute altitude locating ring, be connected by support column between described top absolute altitude locating ring and the bottom absolute altitude locating ring.
Described upper guide is the guiding centrum to keeper, and the side arm of described guiding centrum is provided with limited block.
Described bottom absolute altitude locating ring is fixed on the shaft bottom by setscrew.
The utility model adopts said structure, has the following advantages: 1, realize that by locator itself steel core concrete column and basis or cushion cap top have certain space, the eliminating concrete in the filling concrete process pressure and form the concrete outsourcing; 2, there is larger space effectively to avoid the coarse grained stuck issue of concrete between each assembly of locator; Overlap with the measurement at well head center when 3, locator self top formation right-angled intersection point is convenient to the locator installation; 4, the locator bearing partly adopts the danger that setscrew has fixedly avoided the shaft bottom welding operation to cause.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model;
In Fig. 1 ~ Fig. 2,1, upper guide is to keeper; 2, top absolute altitude locating ring; 3, bottom absolute altitude locating ring; 4, support column; 5, setscrew.
The specific embodiment
Such as Fig. 1 ~ a kind of locator that is applied to the steel core concrete column contrary sequence method shown in Figure 2, comprise upper guide to keeper 1, top absolute altitude locating ring 2, bottom absolute altitude locating ring 3, be connected by support column 4 between top absolute altitude locating ring 2 and the bottom absolute altitude locating ring 3.Upper guide is the guiding centrum to keeper 1, and the side arm of described guiding centrum is provided with limited block.Bottom absolute altitude locating ring 3 is fixed on the shaft bottom by setscrew 5.
Realize that by locator itself certain space is arranged at steel core concrete column and basis or cushion cap top, the eliminating concrete in the filling concrete process pressure and form the concrete outsourcing.There is larger space effectively to avoid the coarse grained stuck issue of concrete between each assembly of locator, when being convenient to the locator installation, locator self top formation right-angled intersection point overlaps the danger that the locator bearing partly adopts setscrew fixedly to avoid the shaft bottom welding operation to cause with the measurement at well head center.By bottom absolute altitude locating ring locator is fixed on the design elevation of shaft bottom, steel core concrete column is inserted on the design elevation, by locator Self-adjustment deviation, in concrete filled steel tube, inject concrete and form steel core concrete column.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
Claims (3)
1. locator that is applied to the steel core concrete column contrary sequence method, it is characterized in that: comprise upper guide to keeper (1), top absolute altitude locating ring (2), bottom absolute altitude locating ring (3), be connected by support column (4) between described top absolute altitude locating ring (2) and the bottom absolute altitude locating ring (3).
2. a kind of locator that is applied to the steel core concrete column contrary sequence method according to claim 1 is characterized in that: described upper guide is the guiding centrum to keeper (1), and the side arm of described guiding centrum is provided with limited block.
