Technical Field
[0001] The utility model relates to the field of concrete product production, in particular to a casting jig for the welding position of an annular concrete electric pole. Background Art
[0002] Circular concrete poles are poles made of concrete and steel bars or steel wires, and the length of the poles is generally 4.5 to 15 meters. There are two types of circular poles: conical poles and equal-diameter poles. The tip diameter of the conical pole is generally 100 to 230 mm, and the taper is 1:75; the diameter of the equal-diameter pole is 300 to 550 mm; the wall thickness of both is 30 to 60 mm. In recent years, with the transformation of rural power grids and the construction of mobile communications in my country, the production and application of circular concrete poles have developed rapidly.
[0003] When the length of a 15-meter pole cannot meet the use requirements, two circular concrete poles are welded and lengthened to make a welded and lengthened circular concrete pole. The steel pipes at the welding point are generally treated with anti-rust paint. This treatment method has a poor anti-rust effect. Rust on the steel pipes at the connection will reduce the strength of the pole, posing a safety hazard. Therefore, a casting mold for the welding point of a circular concrete pole is proposed to solve the above problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Reference Figure 1-Figure 3 The utility model provides an embodiment: a casting jig for an annular concrete pole welding part, comprising a pole body 1 and a vibrating rod 4, wherein the vibrating rod 4 is a prior art, and during the concrete pouring process, the vibrating rod 4 is used to stir the filled concrete, so that the internal gap is fully filled, and the outer wall of the pole body 1 is detachably mounted with two groups of annular cover plates 2, wherein the annular cover plates 2 are provided with two groups, and the outer side walls of the two groups of annular cover plates 2 are in contact with the outer wall of the fixed plate 31, and the outer wall of the pole body 1 is detachably mounted with a trough casting jig 3, wherein the trough casting jig 3 is made of a steel plate as a whole, and the trough casting jig 3 comprises a fixed plate 31, and the connection between the fixed plate 31 and the fixed plate 31 is provided with a plurality of grooves. A plurality of bolt holes are provided so as to fit with M10 bolts to splice and fix the two sets of fixing plates 31 together. Two sets of fixing plates 31 are provided. The inner side walls of the two sets of fixing plates 31 are in contact with the outer wall of the pole body 1. The contact position between the two is the outer wall of the steel pipe at the welding place of the pole body 1. A material guide trough 32 is fixedly connected to the bottom end of the outer wall of the fixing plate 31. The shape of the material guide trough 32 is funnel-shaped. By setting the material guide trough 32 to be funnel-shaped, it is convenient to pour concrete from the top. A slot plate 33 is fixedly connected to the bottom end of the outer wall of the material guide trough 32. Three sets of reinforcing ribs 35 are fixedly connected to the surface of the slot plate 33. A plurality of limit plates 34 are fixedly connected to the surface of the slot plate 33.
