Description
Technical field
The utility model relates to the leading sealing of a kind of basic exterior wall ater-casting, belongs to a kind of ater-casting of building engineering field.
Background technology
In recent years, along with the development of construction technology, the engineering of high level, superelevation layer, the big scale of construction is more and more, and the application of ater-casting frequently occurs thereupon.The ater-casting generally can be divided into flexible ater-casting and pouring after settlement by purposes.No matter flexible ater-casting, or pouring after settlement, its retention time is all longer.When the building foundation is positioned at groundwater table when following, adopt traditional ater-casting to stay the mode of establishing, the ater-casting must be built the ater-casting concrete again after main structure construction is finished.This just requires to continue to carry out precipitation, guarantees that groundwater table remains on below the basis, after the ater-casting concrete is finished and built to agent structure, just can stop precipitation.When the building main body construction time is longer, will certainly increase the precipitation expense greatly, increase engineering cost; Foundation Design is exposed to outdoor for a long time, because day and night temperature is bigger, basic exterior wall easily produces flexible crack; After finish on the basis, do not carry out backfill immediately and have potential safety hazard for deep-foundation pit engineering; Simultaneously, not backfill of basic earthwork, the construction with follow-up other operations of influence influences the duration of a project.
The utility model content
The technical problems to be solved in the utility model is: overcome traditional ater-casting precipitation expense height, exterior wall easily produces crack, deep foundation ditch potential safety hazard and influences deficiencies such as duration of a project, provide a kind of and can carry out leading sealing underground water, after finishing, the basis can carry out follow-up works such as external wall waterproof, backfill, can stop the leading sealing of a kind of basic exterior wall ater-casting of precipitation at any time according to requirement of engineering.
The technical scheme that its technical problem that solves the utility model adopts is: the leading sealing of this a kind of basic exterior wall ater-casting, comprise the ater-casting that basic exterior wall, basic exterior wall are provided with, fast easy-to-closing net and water-swellable sealing rod are installed in the side, ater-casting, it is characterized in that: outside left is provided with concrete guide wall in the ater-casting of basic exterior wall, fill the isolation seam of extruded polystyrene board between the ater-casting, setting up leading wall, expansion joint, expansion joint middle part horizontally set rubber fastening band are set leading in the middle of the wall, exterior wall is provided with the bar construction frame within the walls with leading.
Isolate colligation exterior wall reinforcing bar cushion block between seam and the exterior wall outside reinforcing bar, lead within the walls that the side reinforcing bar is provided with the mortar cushion block between stitching with isolation.
The bar construction frame comprises leads within the walls the side reinforcing bar and leads wall outside reinforcing bar, and exterior wall outside reinforcing bar.
Increase concrete guide wall at basic post-pouring belt of outer wall position, lead the wall middle part and stay and establish the shrinkage joint, the middle part, shrinkage joint is provided with rubber fastening band, in project subject construction period, this leads wall both can waterproof, can freely stretch again, did not influence follow-up works such as basic external wall waterproof, backfilling of earthwork.Owing to lead within the walls that side is difficult for installing template, between exterior wall, increase and isolate seam leading wall, isolate seam and adopt extruded polystyrene board to fill, isolate the effect of side template within the walls of leading of having played of stitching.For guaranteeing to lead side thickness of protection tier within the walls, colligation mortar cushion block on inboard reinforcing bar.For guaranteeing the topping of exterior wall outside reinforcing bar, adopt bar dowel as topping, play the effect that extruded polystyrene board is isolated the seam support member simultaneously.
The beneficial effect that the leading sealing of a kind of basic exterior wall of the present utility model ater-casting is had is: increase concrete guide wall at basic post-pouring belt of outer wall position, leading wall middle part stays and establishes the shrinkage joint, the middle part, shrinkage joint is provided with rubber fastening band, in project subject construction period, this leads wall both can waterproof, can freely stretch again, shorten the foundation pit dewatering time, reduce operating expenses; Reduction produces the probability of structural cracks because of day and night temperature between the basement exposure period; Simultaneously, in time carry out backfilling of earthwork after, can carry out the construction of subsequent handlings such as masonry, more reasonably carry out operation and intert, the reduction of erection time; Carry out external wall waterproof, backfilling of earthwork operation after finish on the basis immediately, eliminated the potential safety hazard that deep foundation ditch brings; The timely backfill of foundation ditch has increased the construction plant of main body construction, for civilized construction has been created better condition; Its precipitation time shortens greatly, and pump-out reduces greatly, has protected groundwater resources effectively.
