Abstract
The utility model relates to a tower foot connection leg device for a power transmission tower. The connection leg device comprises a column body. Flange plates which are used for being connected with tower feet and a concrete tower foundation are respectively arranged at the upper end and the lower end of the column body, bolt holes are formed in the flange plates, and reinforcing ribs connected with the upper flange plate and the lower flange plate are arranged at the periphery of the column body. Compared with the prior art, the tower foot connection leg device has the advantages of being wide in application range, small in field construction area, good in correcting effect, excellent in economy and practicability and the like.
Description
Technical field
The utility model relates to a kind of power transmission tower attending device, especially relates to a kind of column foot for power transmission tower and connects leg device.
Background technology
The inclination of building is a problem that exists in worldwide, and Leaning Tower of Pisa, Italy is the most famous inclined building, the also run-off the straight of Huqiu, China Suzhou tower.The inclination of building generally be since the construction of the asymmetry of place distribution of strata or contiguous new building cause down soil layer different parts generation differential deformation for sleeping in extremely.The inclination of building not only can be brought out disadvantageous subgrade reaction in big sedimentation side (but also claiming soft side) and concentrates, and then As time goes on aggravates the inclination of building, finally may cause collapsing of building.
When the iron tower run-off the straight, need take rational measure to handle.To the transmission line of electricity that has moved, common processing method is mainly by two big classes: a class is the strange land transformation, i.e. near route selection again existing line, and newly-built one basic iron tower is replaced; Another kind of then is to the iron tower that the tilts processing of rectifying a deviation.
The correction of iron tower of power transmission line is very different with the correction of industry with civilian construction: on the one hand, the transmission line of electricity undertaker send the task of electricity power supply, tower body itself is not only only considered in its correction, also need consider the economic society influence that the iron tower power cut construction brings simultaneously.On the other hand, iron tower belongs to tall and slender structure, and it is stressed based on horizontal loading, wherein mainly comprises lines load and wind load, has larger difference with the industry of generally bearing vertical load and civilian construction.
The utility model content
The purpose of this utility model is exactly to provide a kind of column foot for power transmission tower to connect leg device for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of column foot for power transmission tower connects leg device, the described leg device that connects comprises a cylinder, described cylinder two ends up and down is respectively equipped with for the flange that connects column foot and concrete column foot, offer bolt hole on this flange, be provided with the reinforcing rib of lower flange in a plurality of connections around the described cylinder.
The shape that is positioned at the column foot plate on shape and the column foot of flange of cylinder upper end is consistent.
Described reinforcing rib is provided with 12 at least, evenly arranges around cylinder.
The middle position of described spiro keyhole position between adjacent two reinforcing ribs.
Compared with prior art, the utility model connects leg by setting up at the column foot place, with bed hedgehopping should the place column foot position, realize the correction of electric power pylon, have applied widely, characteristics such as the place construction area is little, and rectifying effect is good, and economy and practicality are good; There is differential settlement for the basis, and continues the situation of development, can also at first carry out consolidation process to foundation, adopt this device to rectify a deviation again.In addition, this device can also be implemented charged correction to iron tower, better reduces because the economic loss that power cut construction brings more.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic cross-section at A-A place.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As depicted in figs. 1 and 2, a kind of column foot for power transmission tower connects leg device, connect leg device and comprise a cylinder 1, described cylinder is respectively equipped with for the flange 2 that connects column foot and concrete column foot at two ends about in the of 1, the shape that is positioned at the flange 2 of cylinder upper end need be consistent with the shape of column foot plate on the column foot, and is firm with what guarantee to connect.All offer bolt hole 3 on two flange 2 up and down, be provided with the reinforcing rib 4 of lower flange 2 in a plurality of connections around the cylinder 1.In the present embodiment, reinforcing rib is provided with 16, evenly arranges around cylinder 1, and the interval is 22.5 ° between each reinforcing rib 4, and bolt hole is the middle position between adjacent two reinforcing ribs 4 then.
The utility model connects leg by setting up at the column foot place, be somebody's turn to do the column foot position at place with bed hedgehopping, realize the correction of electric power pylon, have applied widelyly, the place construction area is little, and rectifying effect is good, characteristics such as economy and practicality are good, mainly be applicable to following several situation: 1, since the iron tower that uneven settlement of foundation produces tilt: body of the tower does not deform or other tops such as unstability are destroyed, and foundation has been finished sedimentation, no longer continues to take place the iron tower of foundation deformation.2, since the iron tower that design or construction error produce tilt: differential settlement does not take place in ground, and body of the tower does not deform or other tops such as unstability are destroyed, and makes the iron tower inclination because pre-error partially appears in the pre-deviator error that designing institute is set or work progress.3, tower is angle steel tower or steel tube tower.
Claims (4)
1. a column foot that is used for power transmission tower connects leg device, it is characterized in that, the described leg device that connects comprises a cylinder, described cylinder two ends up and down is respectively equipped with for the flange that connects column foot and concrete column foot, offer bolt hole on this flange, be provided with the reinforcing rib of lower flange in a plurality of connections around the described cylinder.
2. a kind of column foot for power transmission tower according to claim 1 connects leg device, it is characterized in that, the shape that is positioned at the column foot plate on shape and the column foot of flange of cylinder upper end is consistent.
