Wall-through sleeve capable of fixing external wall heat-preservation plate to prevent water seepage of external wall

Abstract

The invention discloses a wall-through sleeve capable of fixing an external wall heat-preservation plate to prevent water seepage of an external wall. The wall-through sleeve comprises a wall-throughpipe, a flange and a pipe plug; the flange is arranged at one end of the wall-through pipe, and a flange internal hole notched table is arranged on the periphery of a flange internal hole; and a pipeplug head matched with the wall-through pipe in internal diameter is arranged at one end of the pipe plug, and a pipe plug cap matched with the flange internal hole notched table arranged on the periphery of the flange internal hole in diameter is arranged at the other end of the pipe plug. According to the wall-through sleeve, the functions of a traditional wall-through sleeve and a heat-preservation bolt are combined into one, the wall-through sleeve replaces the heat-preservation bolt while being used for mounting of a fastener, the wall-through sleeve achieves the good fixing effect on theexternal wall heat-preservation plate, and falling and cracking of the external wall heat-preservation plate can be reduced; the wall-through pipe is filled with foamed adhesive, and thus the water seepage problem of the external wall can be solved; and the pipe plug cap is sunken into the flange internal hole notched table on the periphery of the flange internal hole, the thickness of a late plastering surface layer is decreased, and the purpose of improving the construction quality, reducing construction consumables, simplifying the construction process and lowering the construction cost are achieved.

Description

technical field [0001] The invention relates to the technical field of building material manufacturing, in particular to a wall-piercing sleeve capable of fixing an external wall insulation board to prevent external wall water seepage. Background technique [0002] At present, the construction process of the external formwork composite thermal insulation system is to first stand the external wall thermal insulation board on the outside of the concrete external wall with thermal insulation anchor bolts, then punch holes in the external wall thermal insulation board, and place the wall-through sleeve for installing fasteners Pipe, and then pass the fastening bolt rod through the wall sleeve to fasten the inner and outer formwork, and then pour concrete. There are following defects in this construction process: [0003] First of all, the wall-piercing sleeve used only plays a channel role for the installation of fastening bolt rods. The wall-piercing sleeve cannot be taken ou...

AI Technical Summary

Problems solved by technology

The wall bushing cannot be taken out after the formwork is removed to take out the fastening bolt rod, which not only wastes construction materials, but also causes water seepage on the outer wall

Although the inner hole of the wall casing is filled with foam glue, sealed with waterproof mortar, and painted with polyurethane waterproof paint, there will still be water seepage on the outer wall

The second is that the wall-piercing sleeve is punched through the external wall insulation board, which not only fails to reinforce the external wall insulation board, but also destroys the strength of the external wall insulation board, causing the outer wall insulation board to crack easily

Third, during the concrete vibration process, some thermal insulation anchor bolts will loosen and protrude from the external wall insulation board, which not only makes the thermal insulation anchor bolts lose the fixing effect of the external wall insulation board, but also causes the external wall insulation board to fall off easily

Fourth, the loose insulation anchor bolt protruding from the external wall insulation board will also increase the thickness of the plastering surface layer in the later stage, increasing the consumption of construction materials and man-hours

Fifth, each external wall insulation board must be nailed with an insulation anchor bolt, the construction process is cumbersome, and the construction cost is increased

[0004] Due to the above defects, the construction process is cumbersome, the construction quality is not high, the construction consumables are increased, and the construction cost is increased.
