Abstract
A basement outer wall post-cast strip assembly type advanced backfilling structure comprises outer walls, a top plate, a waterproof layer and a protective layer, wherein bulges are arranged at the bottom of the outer walls; the protective layer is arranged on the outer sides of the outer wall and the top board, and a waterproof layer is arranged between the protective layer and the outer wall; and a post-cast strip is arranged above the top plate between the two outer walls, and a single-side formwork is arranged on the inner side of the post-cast strip. The utility model realizes the operation of backfilling the basement roof in advance, after the post-cast strip reaches the designed casting condition, self-compacting concrete is poured through the vertical pipe, and the final casting of the post-cast strip is realized by utilizing the characteristics that the self-compacting concrete has strong fluidity, does not need external force vibration, can flow under the action of self weight and is full of space; the sealing construction process is effectively simplified, and the basement earthwork backfilling progress is accelerated.
Description
Technical Field
The utility model relates to a post-cast strip technical field, concretely relates to basement outer wall post-cast strip assembled structure of backfilling in advance.
Background
In the building construction, the post-cast strip is arranged to prevent the reinforced concrete structure from generating harmful cracks due to uneven settlement, temperature and shrinkage, and reduce the damage to the structural integrity. According to the requirements of relevant standards, the post-cast strip can be constructed after certain conditions are met. However, more and more projects are limited by the construction period at present, the processes of basement side wall soil reclamation, outdoor pipe network, road, landscape greening and the like are alternated in advance, and the traditional post-cast strip construction method is mainly limited by the construction time, so that the development of related follow-up work is greatly influenced. Basement outer wall post-cast strip assembled structure of backfilling in advance, the outer wall post-cast strip seals usually and is the peripheral brickwork of building of post-cast strip, but because the long period intensity of brickwork period can appear the condition that the brickwork enclosure is destroyed by earthwork backfill machinery inadequately, and need plaster before the waterproofing membrane is pasted outward to the brickwork and make level, the construction is comparatively loaded down with trivial details and the cycle length is unfavorable for outdoor return native stringing.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is, overcome the above-mentioned defect that prior art exists, provide the construction simple and easy, practice thrift time limit for a project and the good advanced structure of backfilling of basement outer wall post-cast strip assembled.
The utility model provides a technical scheme that its technical problem adopted is: a basement outer wall post-cast strip assembly type advanced backfilling structure comprises outer walls, a top plate, a waterproof layer and a protective layer, wherein bulges are arranged at the bottom of the outer walls, grooves matched with the bulges are formed in the two ends of the upper portion of the top plate, the grooves in the two ends of the top plate are respectively clamped with the bulges of the two outer walls, a water stopping layer is arranged at the bottom of the inner side of each groove, and a glue layer is arranged on the side wall of the inner side of each groove; the protective layer is arranged on the outer sides of the outer wall and the top board, and a waterproof layer is arranged between the protective layer and the outer wall; and a post-cast strip is arranged above the top plate between the two ends of the outer wall, and a single-side formwork is arranged on the inner side of the post-cast strip.
Furthermore, the outer sides of the two ends of the top plate are inclined planes.
Furthermore, the glue layer is epoxy resin stone glue.
Further, the water stopping layer is an expansion water stopping strip.
Furthermore, the waterproof layer is a waterproof coiled material of SBS modified asphalt.
Further, the protective layer is an EPS molding polystyrene board or brick masonry protective layer.
Furthermore, the waterproof coiled material is lapped up and down by 80mm, and the waterproof coiled material extends to the two sides of the post-cast strip by 300 mm.
The utility model has the advantages that the advanced backfilling operation of the basement roof is realized, and the outdoor procedures of outdoor pipe networks, roads, landscape greening and the like are alternated in advance; after the post-cast strip reaches the designed casting condition, the final casting of the post-cast strip is realized by utilizing the characteristics that the self-compacting concrete has strong fluidity, does not need external vibration, can flow under the action of self weight and is full of space; the sealing construction process is effectively simplified, and the basement earthwork backfilling progress is accelerated.
