Abstract

The invention provides an advanced water-stopping isolation structure of a later poured band for a basement, which comprises early poured armored concrete slabs positioned at both sides of the later poured band, extending flanges are both arranged below the later poured band on the early poured armored concrete slabs at the two sides, and a rubber water-stopping band is arranged between the two extending flanges, wherein both ends of the rubber water-stopping band are respectively inserted in the two extending flanges. Before the concreting of the later poured band, the water-stopping isolation can be effectively realized inside and outside building structures, so that water-dropping expense is reduced. Meanwhile, the earthwork backfilling construction can be carried out as soon as possible, the eliminate safety management hidden dangers of a foundation pit is eliminated, the operation fields of construction sites is increased, and advantages for the safe production and civil construction management of the construction sites are created.

Description

The leading sealing isolation structure of a kind of basement post-pouring zone

Technical field

The present invention relates to the realm of building construction, be specifically related to the leading sealing isolation structure of a kind of basement post-pouring zone.

Background technology

Along with the continuous development of Building technology, building underground space utilization development is rapid, and the building basement is increasing, more and more darker; Basement post-pouring zone is essential as the structure safety control measure, and the ater-casting often need just can build after main structure construction is accomplished, when the basement base arrangement is positioned at groundwater table when following; Pour in indoorly for fear of underground water, need continue to carry out precipitation, remain on below the basement bottom board structure to guarantee groundwater table; After main structure construction is accomplished and is built the ater-casting concrete, can stop precipitation, cause high level or super highrise building precipitation time long; The precipitation expense is high; The existence of ater-casting simultaneously influences the pit earthwork backfill, causes the waste in field operation place, is unfavorable for job site safety in production and civilized construction management simultaneously.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of basement post-pouring zone leading sealing isolation structure, can before the concreting of ater-casting, realize effective sealing isolation that building structure is inside and outside, reduces the precipitation expense.

For solving above-mentioned existing technical problem; The present invention adopts following scheme: the leading sealing isolation structure of a kind of basement post-pouring zone; Comprise be positioned at the both sides, ater-casting water armored concrete slab earlier; The below that is positioned at the ater-casting on the armored concrete slab of watering earlier of said both sides is equipped with the extension edge of a wing, is provided with two ends between said two extension edges of a wing and inserts two rubber fastening bands that extend in the edge of a wing respectively.

As preferably, be filled with the filler of soft material between said two extension edges of a wing.Can prevent the space between the extension edge of a wing, concrete or other constructional materials filling both sides, ater-casting, hinder structure normal deformation and displacement, cause the leading sealing isolation structure in ater-casting to destroy.

As preferably, the watering earlier of said both sides is provided with two ends and inserts the downward opening U type steel plate for sealing water that waters earlier in armored concrete slab and the ater-casting respectively between armored concrete slab and the ater-casting.Can prevent ater-casting new-old concrete seam crossing infiltration.

As preferably, saidly water armored concrete slab earlier and extend edge of a wing downside and be overlapped with waterproofing course.The peripheral waterproof of ability implementation structure shortens precipitation time greatly.

As preferably, said waterproofing course and water armored concrete slab earlier and extend between the edge of a wing and be provided with topping.Can protect waterproofing course, underground water gets into the ater-casting to avoid waterproofing course to break afterwards.

As preferably, said waterproofing course downside is provided with bed course.As the construction basis of waterproofing course, simultaneously, this structure is effectively isolated building structure and outer rock-soil layer,

Beneficial effect:

The leading sealing isolation structure of a kind of basement post-pouring zone that the present invention adopts technique scheme to provide can be realized effective sealing isolation that building structure is inside and outside before the concreting of ater-casting, reduce the precipitation expense.Simultaneously, can carry out backfilling of earthwork construction as early as possible, eliminate foundation ditch safety management hidden danger, increase operation place, job site, manage with civilized construction for the job site safety in production and created advantage.

Description of drawings

Fig. 1 is a structural representation of the present invention.

The specific embodiment

As shown in Figure 1; The leading sealing isolation structure of a kind of basement post-pouring zone; Comprise be positioned at 9 both sides, ater-casting water armored concrete slab 1 earlier; The below that is positioned at ater-casting 9 on the armored concrete slab 1 of watering earlier of said both sides is equipped with the extension edge of a wing 2, is provided with two ends between said two extension edges of a wing 2 and inserts two rubber fastening bands 3 that extend in the edges of a wing 2 respectively.Said two are extended the filler 8 that is filled with soft material between the edge of a wing 2.The watering earlier of said both sides is provided with two ends and inserts the downward opening U type steel plate for sealing water 7 that waters earlier in armored concrete slab 1 and the ater-casting 9 respectively between armored concrete slab 1 and the ater-casting 9.The said armored concrete slab 1 that waters earlier is overlapped with waterproofing course 5 with the extension edge of a wing 2 downsides.Said waterproofing course 5 and water armored concrete slab 1 earlier and extend between the edge of a wing 2 and be provided with topping 6.Said waterproofing course 5 downsides are provided with bed course 4.

Filler 8 adopts polyphenyl plate or soft material in this structure, and bed course 4 all adopts concrete with topping 6, and waterproofing course 5 adopts waterproof roll.In the construction, accomplish bed course 4, waterproofing course 5, fish tail and waterproof layer 6 earlier; Accomplish the structure that 9 both sides, ater-casting are watered armored concrete slab 1 earlier and extended the edge of a wing 2 again; The installation of completion rubber fastening band 3 and steel plate for sealing water 7 and fixing in the structure construction procedure; Be specially 9 both sides, ater-casting water armored concrete slab 1 earlier and extend the edge of a wing 2 in the ater-casting during structure on two sides construction one-time-concreting accomplish; Rubber fastening band 3 is installed at the extension edge of a wing 2 reinforcing bar bindings and template erection stage; Be cast in when building and extend in 2 structures of the edge of a wing, steel plate for sealing water 7 installs and fixes in basement post-pouring zone 9 biside plate reinforcing bar bindings, builds during concreting and into waters earlier in the armored concrete slab 1; Filler 8 is filled in the gap of before the concreting of watering the armored concrete slab 1 and the extension edge of a wing 2 thereof earlier of both sides, ater-casting, extending between the edge of a wing in the both sides, ater-casting.

This structure can effectively stop underground water to get into the ater-casting, can realize that the ater-casting shifts to an earlier date sealing, prevents that underground water from pouring in the ater-casting; Can shorten watering time greatly, antiseep, simultaneously; This structure is effectively isolated building structure and outer rock-soil layer, can carry out the backfilling of earthwork construction as early as possible, eliminates foundation ditch safety management hidden danger; Increase operation place, job site, manage with civilized construction for the job site safety in production and created advantage.
