Rebar sleeve grouting connection member for prefabricated assembled type concrete component and connection method

Abstract

The invention discloses a rebar sleeve grouting connection member for a prefabricated assembled type concrete component and a connection method. The rebar sleeve grouting connection member comprises a metal sleeve, a sealing gasket and a grouting structure, the metal sleeve connects an insertion rebar and an embedded rebar, the sealing gasket is arranged at the upper end of the metal sleeve, the grouting structure is formed by a grouting material which is poured in a cavity between the metal sleeve and the insertion rebar, the insertion rebar is a ribbed rebar, and a connection end of the embedded rebar is a threaded connection end; the metal sleeve is divided into an upper sleeve section, a middle connection sleeve section and a lower sleeve section, the upper sleeve section and the middle connection sleeve section form a grouting sleeve, a conical inner cavity is formed inside the upper sleeve section, the inner diameter of the conical inner cavity gradually increases from top to bottom, the lower sleeve section is a threaded connection joint, and a grouting port and an exhaust port are formed in the upper sleeve section. The connection method includes the steps of 1, connecting of the embedded rebar; 2, inserting of the insertion rebar; 3, grouting; and 4, maintaining. The rebar sleeve grouting connection member is reasonable in design, convenient to realize and good in using effect, and rebar connection can be completed simply, conveniently and quickly while reliability in connection is realized.

Description

technical field [0001] The invention belongs to the technical field of construction of prefabricated assembled concrete components, and in particular relates to a steel sleeve grouting connector for prefabricated assembled concrete components and a connection method. Background technique [0002] Prefabricated concrete components are also called prefabricated concrete structures, and prefabricated concrete is referred to as PC (Precast Concrete). Prefabricated prefabricated concrete components are concrete structures that are assembled, connected and partially cast-in-place with concrete prefabricated components as the main component. Foreign concrete prefabricated components and reinforced concrete started almost at the same time, but industrialized prefabricated concrete components in the modern sense were not really developed until half a century ago. [0003] The development of construction industrialization is the fundamental transformation of the construction producti...

AI Technical Summary

Problems solved by technology

However, most of the commonly used sleeves currently have complex internal structures, cumbersome manufacturing processes, high cost, and high requirements for the centering accuracy of the steel bars to be connected. There are defects such as complicated steel bar connection process, high manual labor intensity, and slow connection speed.

In addition, when using the steel sleeve grouting connection method to connect steel bars at present, there is no unified, standardized and specific construction method to follow. In actual construction, it is inevitable that the construction operation is relatively random, irregular, cumbersome, and the construction work is relatively low. , poor connection quality, etc.
