SU101367A1 - The device butt joint reinforcing beams - Google Patents

Description

The invention relates to the design of a butt joint of reinforcement bars prior to the design of reinforced concrete, with anchor cups at the ends.

The production of known butt joints is laborious and requires a large amount of metal and great precision in outlets.

The described butt jointing device differs in the design of paired linings, represented by two but; hutzilindra (a pipe cut on the diametral plane) with tapered portions at the ends, covered with anchor glasses and fixed to them with compression rings wearing on conical parts of paired plates and pressing them to conical washers, put on aji beams.

When loading a butt joint, a self-sticking of the conical ends of the lining between the} crimping pieces and co-washers occurs, which ensures the reliability of the movement with comparative simplicity of manufacturing the metal.

The drawing shows the described device in the longitudinal section.

The installation of the butt-joint device і1pp1 is produced in the following way.

Before skipping reinforcement jjy4KOB, large washer 2, small niaii6a 3, taper washer 4 and supporting ring 5 are put on anchor glasses / conical washer 4.

Tolipi more) And a few) washers are selected from the installation of the compression ring and 1-gauge prefab. end gripping during tensioning of reinforcement by the corresponding device. During the tensioning of the reinforcement, a gap between the end of the valve / 6 and the patient with the patient is inserted into the fork-shaped arms 7. After the installation of the reinforcements;); items to the design position their hot glasses are set; V. Chpr, Ayut odigg npOTjii; Dru) T) GO.

In a usable F-position, two ciliydric pads 8 are applied to the cups, on which conical ends are pressed onto ferrules. The internal space of the junction of reinforced concrete elements is filled with cement cement,

The device of butt joining of reinforcing beams is pre-stressed reinforced concrete structure, HMeiOHiHX at the ends of anchor metal cups, in which the ends of the bars of the reinforcement are bent into consumable hooks, poured into the concrete, HI, e with the use of pair lining a diametrically cut pipe with conical parts at the ends; covering connected anchor glasses and crimp rings fixed on them, put on conical parts of plates and pressing them to conical nuts, put on reinforcing beams and inserted into conical parts of the nipple.
