Problems solved by technology

Usually the sealant plug cannot be taken out and will remain permanently in the building, which is extremely wasteful, and the rubber plug permanently retained in the grouting sleeve will cause discontinuous defects inside the building material
[0004] There are also integral rubber seals that can be taken out. For example, the Chinese invention patent application (publication number: CN111945959A) disclosed a machined full-grouting sleeve multifunctional auxiliary part and its loading and unloading method in 2020. The sealing auxiliary part has a setting The middle cylinder, the first end plug and the second end plug are of an integral structure; although the method of loading and unloading the multi-functional auxiliary

Abstract

The invention discloses a combined multifunctional accessory of a grouting sleeve for steel bar connection and a combined use method. The combined multifunctional accessory comprises a rubber plug, a middle column body part and a rubber column which are connected in a combined mode. A metal lining is arranged in the end, close to the middle cylinder part, of the rubber plug, and a plurality of buckles are arranged on the exposed part of the metal lining and arranged in the first end of the middle cylinder part in a clamped and sleeved mode. A boss is arranged at the end, close to the middle column body part, of the rubber column and connected into the second end of the middle column body part through threads. The end where the rubber column is located is sleeved with a positioning screw rod with a pressing check ring, the positioning screw rod penetrates through the rubber column and the boss and extends into the middle column body part, and the exposed part of the positioning screw rod is detachably sleeved with a gasket and a locking nut. The rubber plug can be replaced at any time in the splitting structure, and is convenient to mount and easy to split.

Description

technical field [0001] The invention relates to the technical field of grouting sleeves, in particular to a combined multifunctional accessory of a grouting sleeve for steel bar connection and a combined use method thereof. Background technique [0002] The grouting sleeve for steel bar connection is an important part for steel bar connection in the field construction process. With the development of prefabricated buildings, its application has become more and more mature. The grouting sleeve solves the problem of inconvenient connection of the prefabricated on-site assembled steel bars. It improves the construction efficiency and saves time, manpower and site costs. [0003] No matter in the prefabrication factory or on-site assembly, it is indispensable to seal the rubber plug and the rubber column. The rubber column realizes the positioning of the grouting sleeve on the end plate of the prefabricated formwork, and plays a sealing role to prevent the pouring process. The...
