Problems solved by technology

When operating, first install one end of the connecting sleeve on the end of the basic steel bar and tighten it in place with a pipe wrench, then clamp the connecting sleeve in different directions, and pass the steel bar to be connected through the different direction clamps. The hole is centered, screwed into the connecting sleeve and tightened in place, the construction is relatively difficult, and the quality is not easy to guarantee

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] The present invention mainly comprises following processing steps:

[0022] 1. Straighten the steel bars;

[0023] 2. Cut out the tenon at the end of the steel bar: such as figure 1 As shown, the end of the steel bar 1 is first cut from the middle along the axial direction of the steel bar, with a length of 100 mm, and then half of the cut is removed to form the tenon 2;

[0024] 3. Butt the tenons of the two steel bars, use the matching fasteners to fit the butt joints of the steel bars, and tighten the bolts on the fasteners.

[0025] The present invention also provides a fastener that can be used in conjunction with the above method. Such as figure 2 As shown, the fastener is composed of two symmetrical steel semi-cylindrical bodies 3 . One side of the two bodies is connected together by a hinge 4 , and flanges 5 are provided on the ...

Abstract

The invention relates to a steel bar connection method which mainly includes the following process steps: straightening steel bars; cutting tenons at the ends of the steel bars; joggling the steel bars: a matched fastener is sleeved at the joggled position of the steel bars and bolts are screwed. The invention further provides the fastener used in the method in a matched mode. The fastener is formed by two symmetrical semicircular-cylinder bodies made of steel. One sides of the bodies are connected together through a hinge, and flanges are arranged on the other sides of the bodies respectively. The steel bar connection method is simple to operate and few in processing procedures, reduces labor intensity of workers, improves production efficiency and saves production cost. Meanwhile, the fastener used in the method in a matched mode is simple in structure and convenient to use, can improve mounting and demounting speed and connection reliability, improves the construction quality and facilitates construction management.

Description

technical field [0001] The invention relates to a building construction method, in particular to a steel bar connection method. The invention also relates to a building component, especially a fastener for connecting steel bars. Background technique [0002] At present, there are mainly three types of mechanical connection methods for large-diameter steel bars: [0003] 1. Reinforcement sleeve extrusion connection: Insert the ribbed steel bar to be connected into a special sleeve, and use a hydraulically driven extruder to press several times laterally to cause plastic deformation of the steel sleeve and plastic deformation of the sleeve After that, it will be tightly occluded with the ribbed steel bar to achieve the effect of connection. The crimping force must be able to protect the tight bite between the sleeve and the steel bar. Therefore, the matching degree of the sleeve and the steel bar and the quality of the sleeve are high. When using this method, the processing ...
