Embodiment Construction
[0037] In order to make the purpose of the invention, technical solutions and beneficial effects of the present invention clearer, the embodiments of the present invention will be described below in conjunction with the accompanying drawings. The features in can be combined arbitrarily with each other.
[0038] Example figure 2 as shown, figure 2 Provided is a steel bar connection grouting sleeve with a spare hole 5, which is the same as that of the prior art figure 1 The difference between the grouting sleeves provided in is that the grouting sleeve body 1 is pre-opened with a spare hole 5 that can be opened without damage and a plugging structure that blocks the spare hole 5, and the plugging structure is in the grouting process. Blocking the spare hole allows the grouting sleeve body to form a through passage required for grouting. After the grouting is completed, the plugging structure is taken out without damage (partially taken out, and the protective shell remains i...

The invention relates to a rebar connecting grout sleeve with standby holes and a sleeve connection quality detecting method. The grout sleeve with the standby holes comprises a grout sleeve body, a grout filling hole and a grout discharge hole, wherein the grout filling hole and the grout discharging hole are formed in the grout sleeve body. The standby holes capable of being opened without damage and a blocking structure used for blocking the standby holes are formed in the grout sleeve body in advance. The blocking structure is used for blocking the standby holes in the grouting process, so that a through channel required for grouting is formed in the grout sleeve body. The blocking structure is taken out without damage after grouting is completed. By adoption of the sleeve, the application quality of the rebar connecting grout sleeve in the building construction process can be finally detected. The sleeve and method can be widely applied to construction of fabricated structures of constructional engineering.
Description
technical field [0001] The application provides a grouting sleeve and a method for detecting the connection quality of the sleeve. Background technique [0002] Prefabricated buildings are the development direction of industrial upgrading in the construction industry. The components of prefabricated buildings are connected by sleeves. Therefore, the quality of the connection position is the key point to ensure the quality of prefabricated buildings. At present, prefabricated buildings are still a new technology in my country. In the promotion of each new technology, it is necessary to study and formulate a series of new standards that adapt to my country's domestic quality control system. Such as design standards, project quality acceptance standards, there is no relevant quality control standards at present. [0003] At present, the quality acceptance criteria of construction projects in our country are mainly process control and control after final completion. The curren...
