Abstract

The invention provides a steel bar connector with an inner ring cylindrical structure and a construction method of the steel bar connector. The steel bar connector comprises supporting rings, wherein at least two longitudinal supporting ribs are connected between the supporting ring; three or more than three inner ring supporting ribs are connected onto the inner walls of the longitudinal supporting ribs; the outer diameters of the first supporting rings are identical to those of the second supporting rings; the first supporting rings, the second supporting rings, the longitudinal supporting ribs and the inner ring supporting ribs are connected to form a latticed cylinder body; a cylindrical cavity of which the diameter of the upper part is identical to that of the lower part is formed in the latticed cylinder body; the first supporting rings, the second supporting rings, the inner ring supporting ribs and the longitudinal supporting ribs are connected to form a plurality of space lattices; a metallic sheath is arranged outside the space latticed cylinder body. A preparation method of the steel bar connector comprises the following steps of taking a columnar die and placing the columnar die into the cylindrical cavity, and pouring at the periphery of the columnar die; taking out the columnar die; pouring the concrete into connecting holes and finishing the construction. According to the steel bar connector and the construction method disclosed by the invention, the structure of the steel bar connector in the prior art is thoroughly changed, so that the defects existing in the prior art are overcome.

Description

technical field

[0001] The invention relates to a steel bar connection device used on building objects, which is a steel bar connector with an inner ring cylindrical structure and a construction method thereof. Background technique

[0002] Existing steel bar connector is commonly called as grouting sleeve, and it adopts thicker tube wall to increase the strength of grouting sleeve. But when the tube wall is thicker, the diameter of the sleeve must be larger, and the grouting sleeve with a larger diameter cannot meet the national regulations in use. Concrete thickness requirements, this thickness is collectively referred to as the protective layer, the protective layer requirements for panels and walls is at least 15 mm, and the protective layer thickness of building beams or columns is at least 20 mm. The shortage of this grouting sleeve is: due to the The space is limited. When the position of the longitudinal reinforcement remains unchanged, the thickness of the protecti...

Embodiment Construction

[0014] An inner-ring cylindrical structural steel bar connector according to the present invention includes a first support ring 1 and a second support ring 5, and at least two longitudinal support ribs 3 are connected between the first support ring 1 and the second support ring 5 , more than three inner ring support ribs 4 are connected on the inner wall of a plurality of longitudinal support ribs 3, the outer diameters of the first support ring 1 and the second support ring 5 are equal, the first support ring 1, the second support ring 5, the longitudinal support The ribs 3 and the inner ring support ribs 4 are connected to form a grid-like cylinder. There is a cylinder chamber 7 with the same upper and lower diameters in the grid-like cylinder. The first support ring 1, the second support ring 5, the inner ring support ribs 4 and the longitudinal The supporting ribs 3 are connected to form several space grids 8 , and a metal sleeve 9 is installed outside the cylinder of the ...
