Abstract
The utility model discloses a base for a high-voltage transmission and transformation wire and a communication tower, comprising a base, and a bearing platform surface disposed on the upper end surface of the base. The base for a high-voltage transmission and transformation wire and a communication tower is characterized in that a steel twisted rope is coaxially disposed in the base; a fixing-connecting piece after a stretching-drawing is disposed at the upper end of the steel twisted rope; the upper end of the steel twisted rope and the connecting piece thereof are located in the bearing platform surface; and a bulge is disposed on the steel twisted rope. In the utility model, because a pre-stress steel twisted rope is disposed in the base, the bearing capacity and the stable performance after a long-time service of the base are greatly enhanced; and steel consumption is reduced, so that the resource is saved.
Description
Technical field
The utility model relates to reinforced concrete footing, is specifically related to the defeated modified line of a kind of high pressure, communications tower base.
Background technology
High pressure is failed modified line, communications tower in order to resist wind load and defeated line equipment is pullled, and prevents to topple, and needs firm and stocky base.Traditional tower base is a reinforced concrete structure, and its defective is: not only the base volume is big, and the steel material that need expend is many, and its bearing capacity is also not fully up to expectations, and the step-down of the stability of base meeting as time passes exists potential safety hazard.
Summary of the invention
The technical problem that the utility model will solve provides the defeated modified line of a kind of high pressure, communications tower base, and the base steel using amount is few, and bearing capacity is high, long service life.
The utility model is realized through following technical scheme:
A kind of high pressure is failed modified line, communications tower base; Comprise base, be arranged at the cushion cap face of base upper surface; Characteristics are coaxial prestress steel strand cables that are provided with in the base, and steel strand cable upper end is provided with the fixed connecting piece after the stretch-draw, and said steel strand cable upper end and connector thereof are positioned at the cushion cap face.
The further improvement project of the utility model is that described prestress steel strand cable is provided with convexity (in order to strengthen prestress steel strand cable and concrete adhesion stress).Described convexity is nut or extruding anchor or the concrete precast element that is fixedly connected on the prestress steel strand cable.
The utility model further improvement project is, said prestress steel strand cable along the base limit one week of portion etc. branch arrange.
The utility model further improvement project is that said prestress steel strand cable bottom is bonded in base (greatly
Cause 1/2nd following positions and be bonded in base), top is provided with sleeve pipe, and (the steel strand cable itself has sleeve pipe, and sliding agent is arranged in the sleeve pipe.If the steel strand cable is not established outer tube, then need add sleeve pipe and pipe in-lubricant in addition).Steel strand cable top is provided with sleeve pipe, and the steel strand cable of this part is in free state, is convenient to stretch-draw, forms stress.
The utility model compared with prior art has following advantage:
Therefore the utility model, makes the bearing capacity of base owing in base, be provided with the prestress steel strand cable, and the stability after long-time the use strengthened greatly, simultaneously, has reduced rolled steel dosage, has practiced thrift resource.
Description of drawings
Fig. 1 is the axial cross-sectional schematic of the utility model;
Fig. 2 overlooks enlarged diagram for Fig. 1.
The specific embodiment
As shown in Figure 1, the utility model comprises base 3, is arranged at the cushion cap face 1 of base 3 upper surfaces, is embedded with the stone bolt 5 (also can preset bolt hole) of king-post on the base cushion cap face 1.Still as shown in Figure 1, the coaxial prestress steel strand cable 2 that is provided with in the base 3, said steel strand cable upper end is provided with the fixed connecting piece after the stretch-draw, and said steel strand cable upper end and connector thereof are positioned at the cushion cap face.In the present embodiment, connector is selected anchor clamp for use.Still as shown in Figure 1; Steel strand cable 2 is provided with two convexities 4, and described protruding 4 for being fixedly connected on the extruding anchor of steel strand cable 2, and said steel strand cable bottom is bonded in base 3 (in the present embodiment; Steel strand cable 1/4th following positions are bonded in base 3), top is provided with sleeve pipe 6.
As shown in Figure 2, steel strand cable 2 is arranged along branches such as base one weeks of 3 limit portions.
The utility model prepares process: when colligation base reinforcing cage; Set the steel strand cable on request and do corresponding connection; After the concrete strength of base and cushion cap face thereof reaches requirement, the steel strand cable is carried out stretch-draw, behind the tensioning fixation; With concrete the stretch-draw hole on the cushion cap face is tamped again, steel strand cable and connector are embedded in the cushion cap face.
