Cast-in-place integrated heat insulation plate bolt hole plugging device and method

Abstract

The invention provides a cast-in-place integrated heat insulation plate bolt hole plugging device and method. The plugging device comprises a shrinkable end plugging part and a grouting pipe. The endplugging part penetrates through a bolt hole when shrinking, and the end plugging part plugs one end of the bolt hole when unfolded. A first clamping structure is formed on one side of the end plugging part. A second clamping structure is arranged at the end of the grouting pipe, and the second clamping structure and the first clamping structure are matched and clamped. According to the cast-in-place integrated heat insulation plate bolt hole plugging device and method, the bolt hole can be plugged on the inner side of a wall at a major structure construction stage, and it is avoided that dueto the fact that the indwelling time of the bolt hole is too long, rainwater immerging is caused, and the heat insulation effect is influenced; and meanwhile the defects that aerial plugging is carried out on the outer side of the wall, and consequently the risk is high, the efficiency is low, and the cost is high are avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a bolt hole plugging device and a plugging method of a cast-in-place integrated thermal insulation board. Background technique [0002] At present, prefabricated buildings are becoming more and more popular, and more and more projects adopt cast-in-place integrated thermal insulation, that is, the external wall thermal insulation is constructed simultaneously during the construction stage of the main structure, but after the thermal insulation is completed with the structural construction, there will be left bolt holes. The traditional sealing The plugging technology is in the construction phase of the external decoration, using hanging baskets and other high-altitude operations to block the bolt holes on the outside of the external wall. If the plugging is not timely, it is very easy to cause rainwater to soak into the insulation board and cause damage to the finish...

AI Technical Summary

Problems solved by technology

[0003] In view of the above situation, the present invention provides a bolt hole plugging device and a plugging method for cast-in-place integrated thermal insulation boards that are convenient in construction and do not require facilities such as hanging baskets or climbing frames on the outside of the wall, so as to solve the existing high-altitude plugging of bolt holes For the defects of time-consuming, high cost, high risk and low construction efficiency, the end plugging part is pushed from the end of the bolt hole close to the indoor side to the bolt hole close to the outdoor side by clamping the grouting pipe and the end plugging part. After one end, the connection between the end plugging piece and the grouting pipe is cancelled, and then the grouting is used for plugging. The construction is convenient and efficient, and can effectively save time and construction costs.
