Abstract
A basement outer wall post-cast strip ahead water stopping structure comprises basement outer wall inner side reinforcing steel bars at a post-cast strip opening. The post-cast strip opening is sealed in advance with a prefabricated concrete cover plate. The whole prefabricated concrete cover plate is rectangular. The left and the right of the prefabricated concrete cover plate are respectively in lap joint with the basement outer walls on two sides of the post-cast strip opening. Two-way reinforcement is embedded inside the prefabricated concrete cover plate. Pull rings for hoisting are further pre-embedded into the inner side of the prefabricated concrete cover plate. The basement outer wall post-cast strip ahead water stopping structure is clear in construction, simple to construct and applicable to underground projects such as large basements and underground garages, and smooth outer wall waterproof and backfill subsequent construction before post-cast strip pouring can be guaranteed.
Description
Technical field
The utility model relates to a kind of poured band of outer wall of basement structure.
Background technology
In the in-situ concrete wall construction of building, be the shrinkage stress that reduces to produce due to temperature and the differential settlement solving due to the different generations of superstructure, outer wall of basement generally arranges ater-casting by 30m left and right.Foreign material inevitably can be dropped in ater-casting before sealing, cleaning difficulty, and rainwater and construction water easily enter in basement, affect normal construction; Post-pouring belt of outer wall the normal construction that affects external wall waterproof, outdoor backfill is set, make troubles to the management of job site.
Before building, ater-casting cannot carry out external wall waterproof and the construction of basement backfill without good construction party rule in recent years, particularly in the narrow and small situation that cannot meet execution conditions in construction plant, for reaching management, owner requires duration node, in work progress, need to adopt a kind of new late poured band structure and form of construction work, guarantee carrying out smoothly of work items.
Utility model content
The utility model provides a kind of poured band of outer wall of basement advanced water-stopping structure, solve that the existing basement post-pouring zone construction period is long, operation easier is large, and ater-casting high technical problem of cleaning up cost while building.
The utility model solves the technical scheme that its technical problem adopts:
This poured band of outer wall of basement advanced water-stopping structure, comprise reinforcing bar inside the outer wall of basement at hole, ater-casting place, hole place, described ater-casting is sealed in advance by precast concrete cover, precast concrete cover entirety is rectangle, and its right and left overlaps with the outer wall of basement of both sides, hole, ater-casting respectively; Described precast concrete cover inside is embedded with double-layer double-direction arrangement of reinforcement, and described precast concrete cover inner side is also embedded with the draw ring of lifting use, and the lifting post-tensioning ring that puts in place is connected by reinforcing bar inside the outer wall of basement at iron wire and hole, ater-casting place.
The right and left of described precast concrete cover is than the wide 100～200mm in ater-casting hole.
The outer facade the right and left of described precast concrete cover is ramped shaped.
The outer facade of described precast concrete cover is provided with floated coat.
The outer facade of described precast concrete cover is provided with building waterproof layer.
The beneficial effects of the utility model are as follows:
Late poured band structure of the present utility model adopts precast concrete cover advanced water-stopping, and structure is clear and definite, easy construction.Outer wall of basement waterproofing course, topping and outdoor backfill can integrated constructions, guaranteed outer wall of basement waterproof integral construction quality.In basement, building decorative engineering by laying bricks or stones can synchronously carry out, and has accelerated engineering construction progress.
The utility model has been saved the quadratic cost of base treatment, waterproof and the topping etc. of conventional way after the concreting of ater-casting; simultaneously seal in advance while having avoided conventional unlimited way because rubbish incidental enters the cleaning up cost of interior generation and construction water, rainwater etc. and enter drawing water and cleaning up cost of the indoor generation of basement because of ater-casting, there is good economic benefit.
The social benefit the utlity model has is as follows:
1, external wall waterproof, stemming operation are fulfiled ahead of schedule, the general layout that is conducive to upper body construction completes early, is conducive to on-the-spot civilized construction.
2, basement can be sealed early, avoid the intrusion of rainwater, construction water and foreign material, be conducive to the expansion of indoor engineering and being dried neatly of place.
3, be conducive to the insertion in advance of tube net outside and landscape engineering, meet formation early and the macromarketing plan of Construction unit's sale displaying face.
The utility model is applicable to the underground constructions such as various big basements, underground garage, guaranteed carrying out in advance of external wall waterproof before the sealing of ater-casting, backfill construction, for convenience has been created in follow-up construction.
