Detailed Description

The following detailed description of the present invention will be provided in conjunction with the accompanying drawings and specific embodiments for the purpose of more clearly understanding the structure and the operation of the present invention, which should not be taken as limiting the scope of the present invention.

The first embodiment of the steel wire positioning fixture of the present invention is shown in fig. 1 to 3. The fixture 1 is a cylinder (the cross section is circular ring shape) with a core hole 3, the outer diameter size is determined according to the wall thickness of a product to be cast, the height-diameter ratio of the outer wall is 1.2:1, the core part of 2 end faces is concave along the cambered surface, and the diameter of the core hole 3 is determined according to the diameter of a steel wire 4 to be positioned. The fixture 1 is provided with 1 equal-gap clamping grooves 2 which radially penetrate from the outer wall of the circular ring to the core hole 3, and the gaps of the clamping grooves 2 are slightly smaller than the diameter of the steel wire 4.

When producing thin-wall concrete or cement products, firstly cutting the steel wire 4 according to the design requirements, selecting a fixture 1 with a proper specification (the diameter of a core hole 3 is matched with that of the steel wire 4, and the outer diameter of the fixture 1 is matched with the thickness of the thin-wall product), aligning the clamping groove 2 of the fixture 1 with the steel wire 4, and sliding the steel wire 4 to the core hole 3 along the clamping groove 2 by hand. The fixture 1 is made of nylon and has certain elasticity, and the steel wire 4 slides through the narrow-gap clamping groove 2 to reach the core hole 3 under the action of external force, so that the fixture 1 at the position 1 is installed.

After a proper number of fixtures 1 are arranged on the steel wires 4 according to the size of the product, the steel wires 4 are laid in the template 5, and the prepared concrete or cement mixture is poured, so that the pouring molding of the product can be completed. In the product, the steel wire 4 is positioned at the center of the section of the product (the distance from the 2 surfaces is equal), and the outer diameter of the fixture 1 is the wall thickness of the formed product.

In the present embodiment, the aspect ratio of the jig 1 is 1.2: 1. For thin-walled products, the steel wire 4 has a small diameter and low rigidity, and it is difficult to provide a stopper in the template during molding (fixing the fittings at the mutual positions between the templates to prevent the template from deforming to cause the wall thickness of the product to be too poor), so the fixture 1 needs to play a role of the template stopper while positioning the steel wire 4. By adopting the fixture 1 with a smaller height-diameter ratio, although the material can be saved, the bearing capacity is low, the fixture 1 is easy to incline when the steel wire 4 is laid, and the wall thickness of the product is difficult to ensure. Therefore, the present embodiment employs a large height/diameter ratio, and serves to position the wire 4 and also to receive external pressure and the fixed die plate pitch.

The second embodiment of the steel wire positioning fixture of the present invention is shown in fig. 4. The fixture 1 is made of carbon steel and has a height-diameter ratio of 1: 3. The carbon steel has good bonding effect with concrete or cement and has certain fire resistance. The gap of the clamping groove 2 is in a flaring shape, namely the gap at the outer wall is large, and the gap at the core hole 3 is small. And 3 longitudinal (parallel to the direction of the steel wire 4) grooves are distributed on the outer wall. The flaring-shaped clamping groove 2 can facilitate the sliding of the steel wire 4, and the groove on the outer wall can enhance the bonding between the fixture 1 and concrete or cement.

The third embodiment of the steel wire positioning fixture of the present invention is shown in fig. 5 and 6. Chamfers are arranged at two ends of the flaring-shaped clamping groove 2, and a bulge is arranged at the position, close to the core hole 3, of the clamping groove 2. And 5 longitudinal (parallel to the direction of the steel wire 4) convex ribs are distributed on the outer wall. The clamping groove 2 with the chamfer is more beneficial to the sliding of the steel wire 4; the gap at the bulge is minimum, so that the steel wire 4 can be fully ensured not to slip off due to other external force after being in place in the core hole 3; the ribs on the outer wall may enhance the adhesion between the fixture 1 and the concrete or cement. The fixture 1 is made of ceramic materials, the height-diameter ratio of the outer wall of the fixture is 1:2, and the core parts of 2 end faces are concave inwards (the height-diameter ratio of the concave core parts is 1: 6). The ceramic is a refractory material and can be used for thin-wall products with higher requirements on refractory performance.

In addition to the above embodiments and the description of the usage, the steel wire positioning fixture of the present invention has other similar structural components, and the object of the present invention can be accomplished equally. For example, the cross-sectional shape may be a polygon, a cross or a rectangle, and the longitudinal section (i.e., a cross section) may be a circle; non-functional holes can be arranged for saving materials; besides steel wires, the steel wire can also be applied to steel bars with smaller diameters and the like. Modifications and substitutions which will be apparent to those skilled in the art are intended to be included within the scope of the invention.
