Abstract
A combined split bolt belongs to clamp technical field, which comprises a bolt and a nut. The combined split bolt is characterized in that a sleeve pipe is provided to match the bolt which has at least two segments, the bolts are connected by internal screw joint, and the sleeve pipe covers the bolt. The sleeve pipe is plastic pipe; a bell mouth is arranged on the end of sleeve pipe, screw threads more than 0.08m is arranged on both end of the bolt to match the nut. The utility model has advantages of simple rotational structure, easy production, and convenient application. According to the width of different concrete products, a plurality of bolt of different length are selected and connected by internal screw joint. The bolt is in sleeve pipe and concrete is poured, after the concrete product pouring, the bolt can be easily taken out from the sleeve pipe, then the bolt can be repeatedly used by adding another sleeve pipe. The service life of the bolt is prolonged; the project construction cost is reduced, energy is saved, the work efficiency is enhanced, and the utility model has good popularization and application value.
Description
Technical field
The utility model relates to the split bolt that formboard fastening is used in the concrete work building, belongs to technical field of tooling clamps.
Background technology
In the concrete product construction of no waterproof requirement, as bent cap, precast beam etc. under concreting board wall, large-scale single footing, the bridge, all need adopt template, and the split bolt of existing formboard fastening, generally be according to himself width in the concrete product construction at the scene, process single quite long bolt, a sleeve pipe as PVC, steel pipe etc. is worn in the outside, and it is fastening that the template both sides add plain nut with the butterfly clip.
This split bolt, a concrete product build finish after, if there is not the concrete product of same widths, the split bolt of this length has not just temporarily had use value, perhaps will prescind than long bolt to be processed into to meet the split bolt that thin concrete product is built use.Split bolt not only needs a large amount of former materials, and two ends also need mantle fiber, processes the wasting manpower and material resources repeatedly.
The purpose of this utility model be to provide a kind of and economize on resources, combined type split bolt easy to use.
The purpose of this utility model is achieved in that the combined type split bolt, comprises bolt and is used for bolt two ends clamp nut, it is characterized in that being provided with the sleeve pipe that uses with bolt matching, described bolt is at least two sections, has female adapter to be connected between bolt and the bolt, and sleeve pipe is nested with on bolt.
Described sleeve pipe is a plastic pipe, and sleeve end is provided with horn mouth.The two ends of described bolt are respectively equipped with greater than 0.08 meter long and screw thread nut coupling.
The length of bolt can be made into plurality of specifications such as 0.16m, 0.25m, 0.45m, 0.95m, 1.05m, 1.5m, and the bell-mouthed diameter of sleeve pipe can be made into plurality of specifications such as Ф 16, Ф 20, Ф 25, Ф 32.
The utility model is rational in infrastructure simple, manufactures easily, and is easy to use.Bolt places concreting in the sleeve pipe, a concrete product build finish after, bolt can be extracted out in sleeve pipe easily, add a sleeve pipe again, reuses.And can select the bolt of several length specifications to connect according to the concrete product of different in width by female adapter is arranged.Prolong the application life of bolt, reduce the engineering construction cost, economize on resources, use installation convenient, raise labour productivity, the excellent popularization using value is arranged.
