Technical Field
The utility model belongs to the technical field of concrete pole, communication pole, wind power tower section of thick bamboo preparation, especially, relate to a core mould supports concrete pole to muscle area recess.
Background
ZL201410062493.1 discloses a concrete pole with hoop prestress and a manufacturing method thereof, the basic principle is that the tension of the hoop reinforcement is transmitted to a core film through a longitudinal reinforcement to support the hoop reinforcement, and finally transmitted to a core mold, and the core mold is removed after the concrete is cured, so that the hoop stress is transmitted to the concrete to achieve the hoop prestress effect. Although the method can achieve the effect of generating the annular prestress, the core film supporting annular rib is relatively complex to manufacture, the processing efficiency of the hard limiting block or the hard limiting line is low, and the mass production is difficult to a certain extent. The frame force ring of the common concrete pole is simple in structure and also plays a role in supporting the longitudinal ribs, but the frame force ring is buried in the concrete, and the structure mode of the frame force ring cannot generate annular prestress, so that the frame force ring is not beneficial to preventing the concrete from cracking.

Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
As shown in fig. 1, 2 and 3, the utility model discloses a concrete pole of hoop muscle area recess is supported to mandrel, including the concrete pole body 1, evenly distributed is at vertical muscle 2 of this concrete pole body 1, and the mandrel that peripheral and this vertical muscle 2 contacted supports hoop muscle 4, sets up vertical 2 outlying prestressing force hoop muscle 3 of muscle, mandrel support hoop muscle 4, vertical muscle 2 and prestressing force hoop muscle 3 between in proper order in close contact with, its characterized in that is in mandrel support hoop muscle 4 on be equipped with the several to the bellied recess 5 in the centre of a circle, to the bellied recess 5 in the centre of a circle interior salient with the internal surface parallel and level of concrete pole body 1, and with the contact of mandrel surface.
The plurality of grooves 5 protruding towards the circle center are uniformly distributed along the circumference, and the number is larger than or equal to 3.
The mandrel support ring is characterized in that the ribs 4 of the mandrel support ring are equally spaced rings or equally spaced spiral lines, the distance between the ribs 4 of the mandrel support ring is 0.3-1 m, and the ribs 4 of the mandrel support ring are wire rods made of metal or high polymer materials.
The utility model discloses a concrete pole of hoop muscle area recess is supported to mandrel, including concrete pole body 1, mandrel support hoop muscle 4, vertical muscle 2 and outer prestressing force hoop muscle 3 constitute, mandrel support hoop muscle 4 is equidistant ring or equidistant winding helix, and mandrel support hoop muscle 4's interval is 0.3 to 1 meter, and mandrel support hoop muscle 4 can be the wire rod that metal or macromolecular material made. The concrete pole support structure is characterized in that grooves 5 protruding towards the circle center are formed in the mandrel support ring ribs 4, the grooves 5 protruding towards the circle center are uniformly distributed along the circumference, the number of the grooves 5 is larger than or equal to 3, inner convex points of the grooves 5 protruding towards the circle center are flush with the inner surface of a pole body, namely the inner convex points of the grooves 5 are in contact with the outer surface of a mandrel, the position of longitudinal ribs 2 located on the outer layer of the grooves is kept unchanged when radial pressure of outer prestressed ring ribs 3 is applied to the longitudinal ribs by means of rigid mandrel support, the outer diameter of the rigid mandrel is the same as the inner diameter of a concrete pole body 1, and the inner convex points are flush with the inner surface of the concrete pole body 1 after the concrete pole body 1 is formed. The longitudinal ribs 2 are uniformly distributed on the periphery of the mandrel supporting circumferential ribs 4, the outer layer prestressed circumferential ribs 3 are positioned on the periphery of the longitudinal ribs 2 and are wound in a certain tensioning prestressed state, and therefore the concrete pole steel bar framework with the circumferential prestress formed by the mandrel supporting circumferential ribs 4, the longitudinal ribs 2 and the outer layer prestressed circumferential ribs 3 is formed, and the circumferential prestress can be kept unchanged due to the supporting of the rigid mandrel. The rigid core mould with the steel bar framework is placed into the external mould of the rod body, concrete is poured between the core mould and the external mould, the rigid core mould is drawn out after the concrete is solidified, and the circumferential prestress acting on the core mould is transferred to the concrete rod body, so that the concrete rod with the circumferential prestress is manufactured.
The utility model discloses a concrete pole of mandrel support hoop muscle area recess through increase on mandrel support hoop muscle 4 to the bellied recess 5 in the centre of a circle, replaces stereoplasm stopper or stereoplasm spacing line on mandrel support hoop muscle 4, and this kind of recess 5 is fit for mechanized production, and this scheme makes production efficiency improve when guaranteeing hoop prestressing force effect.
