Problems solved by technology

[0008] The semi-grouting sleeve disclosed in Chinese patent document CN102587586A has the above-mentioned advantages, but there are still the following problems: ① The grooves and / or ribs are cast or machined, and the disadvantages of time-consuming and labor-intensive processing have not been fundamentally resolved; ②The grooves and / or convex ribs are made by rolling or spinning, and rely on multiple grooves inside the sleeve to resist shearing. It is required that the wall thickness of the sleeve is relatively large, so as to ensure that the tensile force at the thinnest position of the sleeve wall after rolling (pressing) is greater than the tensile force of the connecting steel bar, which will directly lead to the bulky shape of the sleeve; on the other hand, Machining multiple grooves and / or ribs is still time-consuming and labor-intensive
[0009] In summary, the existing semi-grouting sleeves have disadvantages such as difficult processing, bulky form, and high cost, which is not conducive to the current development of housing industrialization and construction industrialization in China.

Abstract

The invention discloses a shearing reinforcing type semi-grouting sleeve which comprises a sleeve body, wherein the sleeve body is of a tubular structure; an elastic rubber sealing ring is arranged at the opening of one end of the sleeve body; a threaded connecting piece is arranged at the opening of the other end of the sleeve body; a grouting hole and a discharge hole are formed in side walls close to the end parts of the sleeve body; bolt holes are formed in the side wall along the sleeve body; anti-shearing bolts are arranged inside the bolt holes. The shearing reinforcing type semi-grouting sleeve has the advantages of wide material resource, simplicity in machining and manufacturing, reliability in property and the like, can greatly overcome the defects that the conventional cast iron or cast iron steel sleeve is complex to manufacture and high in cost, a mechanical milling sleeve is labor and time waste, and the like, can be widely applied to assembled type concrete structures, and has wide engineering application prospects.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to a slurry-anchored sleeve connector used for connecting steel bars between prefabricated concrete components. Background technique [0002] Prefabricated concrete structures, as a structural form in line with industrial production methods, have the advantages of fast construction speed, low labor intensity, less noise pollution and wet work, and easy control of product quality, and have been widely used in developed countries. The construction method of prefabricated assembly can effectively save resources and energy, improve the utilization rate of materials in realizing building energy saving and structural performance, overcome the restrictions of construction site and environmental conditions on site construction, reduce the number of on-site construction labor force, and reduce construction waste And the adverse impact of construction on the environment, impr...
