Splicing type prefabricated wall body and upper and lower connecting structure thereof

Abstract

The invention belongs to the field of building engineering, and relates to a splicing type prefabricated wall body and an upper and lower connecting structure thereof. According to the technical scheme, a first prefabricated wall body and a second prefabricated wall body are spliced up and down, wherein a first steel pipe is pre-buried at the bottom of the first prefabricated wall body, the upperpart of the first steel pipe is buried in the first prefabricated wall body, and the lower part of the first steel pipe is exposed out of the first prefabricated wall body; a second steel pipe is pre-buried at the bottom of the second prefabricated wall body, the lower part of the second steel pipe is buried in the second prefabricated wall body, and the upper part of the second steel pipe is exposed out of the second prefabricated wall body; the first steel pipe and the second steel pipe are vertically aligned and connected in position; and longitudinally distributed reinforcing steel bars exposed out of the first prefabricated wall body and the second prefabricated wall body are in staggered lap joint anchoring with one another. According to the splicing type prefabricated wall body andthe upper and lower connecting structure thereof, a grouting sleeve is omitted, the upper and lower prefabricated wall bodies are connected with each other through adopting the additionally-arranged upper and lower steel pipes, so that a temporary support is formed, in this way, construction of upper and lower splicing of the prefabricated wall body is facilitated, and meanwhile the cost of the grouting sleeve is saved, and therefore the method is economical and reliable.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to the connection of prefabricated walls and spliced ​​prefabricated walls. Background technique [0002] In the prior art, the upper and lower joints between the prefabricated walls are as follows: part of the longitudinally distributed steel bars of the upper prefabricated wall protrude from the wall, and the exposed longitudinally distributed steel bars extend into the sleeve from top to bottom; the lower prefabricated walls Part of the longitudinally distributed steel bars of the wall protrude from the wall, and the exposed longitudinally distributed steel bars extend into the sleeve from bottom to top; finally, the grouting in the sleeve completes the connection and fixation between the upper and lower steel bars, and joins the horizontal joint of the splicing section. Steel bars, and finally the splicing section of the upper and lower prefabricated walls is ...

Problems solved by technology

However, on the one hand, during on-site construction, the grouting of the grouting sleeve is often not dense, and the quality cannot be guaranteed; on the other hand, there is currently no effective means of detecting the grouting density of the sleeve, resulting in uncontrollable grouting quality
