Description
Technical field
The utility model belongs to building engineering construction field, and in particular to a kind of structure for facilitating structure base slab post-cast strip to clear up
Make.
Background technology
During Current Engineering Construction, in order to solve the relative settlement between main structure body or garage and podium, structure both shrinks
The problems such as deformation and temperature stress are deformed, the mode of indwelling post-cast strip is used widely in architectural engineering.But midsole of constructing
Plate pouring after settlement is only waiting agent structure to bind, and can just be poured after settlement stability, indwelling time is longer, easy ponding,
Product rubbish, and clear up ponding, rubbish workload greatly and be not easily cleaned totally, such as clear up not thorough, after ensureing that post-cast strip is closed
Waterproof quality it is unfavorable.Therefore, on the premise of the stability and agent structure energy smooth construction on basis is ensured, how to bottom plate
Post-cast strip carries out Construction treatment, and before the closing of post-cast strip, internal ponding, garbage-cleaning can reach concreting condition, really
Protect post-cast strip and occur without Seepage, it has also become engineers and technicians constantly inquire into the problem of research.
CN201520302805.1 patent discloses a kind of alter-pouring strips mould plate with tipping platform, and position is installed in alter-pouring strips mould plate
A kind of template with tipping platform has been installed, side is fixed by door hinge, is opened when post-cast strip is cleared up, rubbish is poured out, when pouring
Turnover panel is closed.The alter-pouring strips mould plate that the program is provided installs structure, solves in post-cast strip that construction garbage-cleaning difficulty is big, clear up
The problem of effect is undesirable.But the post-cast strip of floor in balcony is only applicable to, it is not suitable for the cleaning of bottom plate rear pouring tape.
CN201220584882.7 patent discloses a kind of gutter for being applied to cleaning post-cast strip, is set in post-cast strip
There is a gutter, and connected with sump on the outside of wallboard, by sump draining, reached in post-cast strip without ponding, side
Convenient to operate.Construction garbage-cleaning difficulty is big in solution post-cast strip, substantially increase construction efficiency, it is ensured that construction quality.But
In exterior wall and sump connectivity part, closure requires higher, and difficulty is big, and follow-up seepage probability is big, and be not suitable for Underground Extra-long,
The application of super many post-cast strips.
CN201520929186.9 patent discloses a kind of late poured band structure, and one layer of protection steel is set on post-cast strip top
Plate and water-proofing treatment, then carry out top earthing, do not influence earthing to construct again, solve in basement and main structure construction
Be eager backfill when the rear pouring tape construction method that carries out.But exist after earthing, clear up the problem of post-cast strip rubbish is more difficult.
The content of the invention
The technical problems to be solved in the utility model is, in existing industry and civil buildings basement bottom plate rear pouring tape
Ponding and rubbish are difficult to the deficiency cleared up there is provided a kind of construction for facilitating structure base slab post-cast strip to clear up, and are put by fish tail and waterproof layer
The construction that slope is combined with reserved catch pit；Easy construction, labor intensity are low, operating efficiency is high, and cleaning effect is notable.
The utility model is to solve the technical scheme that is used of above-mentioned technical problem：
A kind of construction for facilitating structure base slab post-cast strip to clear up, including some fish tail and waterproof layers and reserved catch pit, waterproof
Protective layer declines in certain slope, rule and rises arrangement, and reserved catch pit is arranged at two fish tail and waterproof layers to form bottom of slope
Between (reserved catch pit connect with the bottom of slope of two fish tail and waterproof layers).
By such scheme, at bottom plate rear pouring tape, fish tail and waterproof layer carries out 3 ‰~5 ‰ towards reserved catch pit direction
Fish tail and waterproof layer between slope, two neighboring reserved catch pit carries out 3 ‰~5 ‰ to reserved catch pit direction respectively with midpoint
Slope.
By such scheme, the reserved catch pit is provided with concrete cushion, brick fetal membrane, SBS waterproof rolls, GRC protections
Plate, concrete water-proof protective layer, concrete cushion are cast in reserved catch pit bottom, and brick fetal membrane is built by laying bricks or stones in reserved catch pit four
Wall, SBS waterproof rolls paving is connected in reserved catch pit and with the fish tail and waterproof layer outside reserved catch pit, concrete
Fish tail and waterproof layer is cast in the reserved catch pit bottom after paving SBS waterproof rolls, and GRC protection boards are bonded in paving SBS waterproofs
The wall of reserved catch pit four after coiled material.
By such scheme, two neighboring reserved catch pit spacing Wei≤20m.
By such scheme, the reserved catch pit width and depth are 0.3~0.5m.
Compared with prior art, the beneficial effects of the utility model are：
1st, it is necessary to which use is a large amount of artificial in traditional basement post-pouring zone scale removal process, and cleaning effect is undesirable, to rear
Pouring the quality with infiltration weak link can not ensure there is high hidden leakage defect, will be prevented using the utility model at post-cast strip
Water conservation layer slope, and the reserved catch pit in post-cast strip, both construction being combined reach the purpose quickly cleared up, dropped
Low basement bottom plate rear pouring tape cleaning work amount, so as to greatly reduce labor intensity, improve that operating efficiency is high, reduce
Construction period, meanwhile, it also ensure that construction quality；
2nd, the utility model construction way utilizes slope, the combined use of catch pit, and post-cast strip is make use of to greatest extent
Internal water accumulation self is collected, and is drawn water in addition using draining pump, is reached the condition without ponding in post-cast strip；
3rd, reserve catch pit and add SBS waterproof rolls plus GRC protection board ways, and SBS waterproof rolls and collection using brick fetal membrane
It is connected as a single entity outside puddle, strengthens the waterproof effect of catch pit and whole engineering, with globality, treats that post-cast strip concrete is poured
When building, the concrete of identical strength grade of concrete, primary concreting can be used with post-cast strip；
4th, compared with traditional basement bottom plate rear pouring tape cleaning effect, the utility model cleaning effect is notable, to post-cast strip
The impervious waterproof quality gone out is significantly increased, and then reduces construction cost.
