Technical Field
The invention relates to a wind-fire wheel type steel bar positioning device and a positioning method thereof, belonging to the field of buildings.
Background
In the field of engineering construction, in order to meet the requirement of a steel bar net protective layer, a steel bar framework is generally provided with a concrete cushion block in a main beam in a house building, and the concrete cushion block is supported between a template and a main steel bar; in the bridge structure, the beam body and the lower part structure steel reinforcement framework can be provided with convex positioning steel bars around the steel reinforcement framework besides the method of arranging the cushion blocks; in order to be under construction simply among pile foundation and the underground structure, generally set up the spacer bar on steel reinforcement framework, in order to guarantee that the spacer bar position is stable, generally be with the spacer bar welding to the main muscle of steel reinforcement cage. The method is simple in construction and easy to operate, but the cushion block is easy to deviate when the concrete is vibrated, the cushion block cannot play a role in positioning the steel bar framework, and the main steel bar is easy to corrode by atmosphere and rainwater due to the fact that the surface is smooth, the cushion block and the main body are easy to separate and cracks appear after the structure is unevenly settled; the positioning steel bars are exposed outside or soaked in underground water, so that the positioning steel bars are easily corroded by rainwater or underground water, and the main stressed steel bars are gradually influenced after the positioning steel bars are corroded, so that the structure is unstable.
Disclosure of Invention
The invention aims to solve the technical problem of providing a wind-fire wheel type steel bar positioning device and a positioning method thereof, wherein the positioning device ensures that a stressed main bar in a steel bar framework is not interfered by corrosion, ensures the stable structure, and has the advantages of simple construction method, extremely low manufacturing cost, easiness in arrangement, flexibility, convenience for workers to master and operate, safety, high efficiency and strong practicability.
In order to solve the above problems, the specific technical scheme of the invention is as follows: the utility model provides a wheeled reinforcing bar positioner of wind fire, is equipped with the preformed hole in the axle center of cylinder body, at the upper and lower surface of cylinder body and outer circumference fixed connection a plurality of filiform muscle areas that add.
The inner circumference of the preformed hole is provided with a raised longitudinal grain parallel to the axial direction.
The upper surface, the lower surface and the outer circumference of the cylinder body are respectively provided with peripheral convex stripes.
The peripheral convex stripes are in a strip shape, a circular shape or a crescent shape.
The reinforced belt is formed by compounding high-strength steel wires with high tensile strength and high corrosion resistance and an externally wrapped polypropylene film.
The method for positioning the steel bar by adopting the positioning device comprises the following steps:
the method comprises the following steps: penetrating a preformed hole of the cylindrical body through a steel bar to be positioned;
step two: arranging the cylindrical body at a preset position, inserting part of the reinforced strip close to the preformed hole into the preformed hole, improving the friction force between the raised longitudinal grains and the reinforcing steel bar, and fixing the position of the cylindrical body;
step three: the outer reinforced belt is distributed and paved along the radial direction;
step four: setting positioning devices at equal intervals in sequence along the length direction of the steel bar according to the length of the steel bar to be positioned, adding one positioning device each time, and repeating the first step to the third step to complete positioning;
step five: and pouring concrete to completely embed the cylindrical body into the concrete and play a role in positioning the reinforcing steel bars.
The utility model provides a wheeled reinforcing bar positioner of wind-fire has adopted the cylinder body that has protruding stripe and the structure that adds up with the reinforced area, the area of contact of positioner with the concrete that has changed mutually makes positioner and the later concreting closely combine, has improved the wholeness between positioner and concrete, has ensured that the interior atress owner muscle of framework of steel reinforcement does not receive the corruption interference. The circular positioning device effectively improves the construction efficiency and ensures that all directions meet the requirements of the protective layer.
The inner circumference of the preformed hole is provided with the raised longitudinal grains, so that the stability of mortar between the disc hole and the reinforcing steel bar is ensured, and the position of the disc is fixed.
Set up protruding stripe at cylinder body periphery, increased the area of contact of positioner with the concrete, improved closely knit degree.
The reinforced belt has the characteristics of high tensile strength, large elastic modulus, strong acid and alkali resistance and good flexibility, can generate enough friction force with the post-cast concrete, and ensures the integral stability of the positioning device and the post-cast concrete.
