Problems solved by technology

[0004] This connection method can achieve a very firm connection between the two prefabricated components under the condition of ensuring the construction quality, but various problems may occur during the construction process, which may cause the steel bars that should be inserted into the sleeve to be cut off or the steel bars are not as long as required. Inserted into the steel bar sleeve, thus affecting the quality of the on-site connection nodes of prefabricated components, so that there are certain safety hazards in the assembled prefabricated building

Embodiment 1

[0024] like figure 1 As shown, it is a schematic diagram of the grouting sleeve-type steel bar joint method after endoscopic detection in this embodiment, which is applicable to the case where the overflow channel 5 and the grouting channel 6 of the sleeve steel bar joint protrude from the outside of the wall. The structure of the post-grouting plug-in sleeve steel bar joint is detected by endoscopy, including the embedded steel bar 1 of the upper member, the embedded steel bar 2 of the lower member, the grouting sleeve 3 and the industrial endoscope, and the top of the grouting sleeve 3 is provided with threads The hole has a groove in the inner cavity, and the pre-embedded steel bar 2 of the lower member is preferably ribbed steel bar to increase the grouting strength. The end of the pre-embedded steel bar 1 of the upper member is threaded and screwed and fixed in the threaded hole on the top of the grouting sleeve 3 . The upper and lower parts of the grouting sleeve 3 are ...

Embodiment 2

[0030] The difference from the previous embodiment is only that the grouting channel 5 and the grouting channel 6 of the sleeve steel joint to be detected in this embodiment are located inside the wall 8, and the grouting channel 6 and the grouting channel 5 are far away from the grouting operation. The face wall 8 is far away, so it is necessary to use a connecting hose to connect the surface of the wall in advance to form an extended grouting channel 6 and a grouting channel 5 . Then the industrial endoscopic probe 4 is sent into the extended channel to carry out the above-mentioned detection work.

[0031] One of the main problems that may arise when using the post-grouting sleeve insertion type steel bar connection method to connect prefabricated building components is whether the steel bar is really completely inserted into the sleeve (whether it may be intercepted for various reasons). The invention uses an industrial endoscope to observe whether the position of the stee...

Abstract

The invention discloses a structure for detecting a post-grouted inserting type sleeve and steel bar connector through an endoscope method and a method applying the structure and belongs to the technical field of detection. Whether the position of a steel bar in a sleeve is in place or not is observed through an industrial endoscope. According to the method, operation is easy and convenient, the result is visual and reliable, the applicable working condition is wide, and the influence of the site construction condition on themethod is less; and meanwhile, whether a grouting channel and an overflowing channel are unobstructed or not can be inspected, and the guarantee is provided for the quality of subsequent grouting construction.

Description

technical field [0001] The invention belongs to the field of detection methods, and in particular relates to a structure and a method of an endoscopic detection post-grouting plug-in sleeve steel bar joint. Background technique [0002] With the continuous development of my country's social economy, the housing industry has also developed rapidly, which has led to the adjustment and upgrading of the entire national economic structure and has become an important pillar industry of the national economy. An important task of my country's current housing construction is to promote the modernization of the housing industry. As an emerging green, environmentally friendly and energy-saving building method, the prefabricated building structure has attracted the attention of real estate developers, construction companies and designers due to its advantages such as fast construction speed, good economic and environmental benefits. The prefabricated building structure is an effective w...
