Description
Technical field
The utility model relates to a kind of prefabricated plate advanced water-stoppings of poured band of outer wall of basement to backfill structure, belong to ground
Lower room exterior wall late poured band structure field.
Background technique
During building basement exterior wall cast-in-place concrete structure construction, in order to cut down concrete shrinkage stress,
Post-cast strip generally can be all arranged in outer wall of basement.Post-cast strip inevitably falls into sundries before closing, and later period cleaning is difficult,
Influence concrete pouring quality；Meanwhile the post-cast strip outer water (construction water, rainwater etc.) of closing cup is easily scurried into basement,
Influence normal construction；In addition, post-pouring belt of outer wall restricts and limit the construction workings times such as outdoor water-proof, outdoor backfill, influence
Construction speed.
Traditional poured band of outer wall of basement processing mode and expense.240 thick wall bodies are built at post-pouring belt of outer wall, in wall
Plastering processing in outer surface can just do waterproof and the construction of masonry process later.But have following hidden danger of quality: 1, outer wall of basement is used
240 building walls, after reaching the post-cast strip concreting time, the unilateral formwork reinforcement difficulty in inside is (with outside without counter brace
Part), easily rise mould quality problems, increases manually pick the expense of beating instead.Traditional approach processing cost: 1,240 walls are built
Expense (fee of material and labour cost, calculated according to comprehensive unit price): 475 yuan/m3 × 3.9m × 0.24m × (0.8+0.3+0.3) m=
622.44 first；2, basement post-pouring zone external wall plastering expense: 50 Yuan/㎡ × 3.9m × (0.8+0.3+0.3+0.24 × 2) m=
366.6 first；3, consider post-cast strip cleaning (because masonry mortar fall off etc. fall off in post-cast strip and post-cast strip steel bar pollution processing)
And unilateral template mounting cost on the inside of the later period: 3 labour cost × 350 yuan/day=1050 yuan.After conventional process outer wall of basement
Pouring band to amount to expense is 2039.04 yuan.
Utility model content
Technical problem to be solved by the utility model is: it is advanced to provide a kind of prefabricated plate of poured band of outer wall of basement
Sealing backfills structure, to solve difficult existing poured band of outer wall of basement sundries cleaning, infiltration influence pouring quality and process
Between contradiction the problem of restricting and extending construction speed.
The technical solution of the utility model is: a kind of prefabricated plate advanced water-stopping backfill knot of poured band of outer wall of basement
Structure, comprising: outer wall of basement and the post-cast strip that outer wall of basement is arranged in, the hole of the post-cast strip is by several prefabricated mixed
Concrete board successively overlaps seal in advance from bottom to up；The precast concrete intralamellar part is embedded with screw rod, matches on screw rod and is arranged
There are butterfly button and fastening nut；The precast slab both sides are outer vertical with the outer wall of basement of post-cast strip hole two sides respectively
Face overlap joint, and screw rod is socketed after pouring with hole by butterfly button and the cross bar for the interior facade for being overlapped on outer wall of basement,
It pushes butterfly button mobile by tightening fastening nut, is tightly attached to precast slab and cross bar on outer wall of basement.
The upper and lower end parts of the precast slab are respectively equipped with card slot and boss, and contiguous prefabricated concrete slab passes through boss
Protrude into clamping in card slot.
Before the hole sealing of post-cast strip, the contact area of contiguous prefabricated concrete slab is pre-coated with ointment, in post-cast strip
After the sealing of hole, the seam crossing of contiguous prefabricated concrete slab is coated with grease seal.
Before the hole sealing of post-cast strip, the contact area of the precast slab and outer wall of basement is pre-coated with oil
Cream, after the hole sealing of post-cast strip, the seam crossing of the precast slab and outer wall of basement is coated with grease seal.
Pre-buried on the precast slab to be provided with hanging ring, the hanging ring and the screw rod are located at precast concrete
The both ends of the surface of plate.
The hanging ring is 2, and the screw rod is 4.
The screw rod is sealing up screw.
Compared with prior art, as follows the advantages of the utility model:
1, conditions to release restricts, the effectively save duration.Using the prefabricated plate in post-cast strip, outer wall of basement waterproof layer,
Protective layer and outdoor backfill can integrated construction, the construction for eliminating post-pouring belt of outer wall restricts, and guarantees waterproof integral construction quality, together
When basement in other processes can be organized to construct, in addition after outdoor backfill, do not influence adjacent building construction, therefore saved work
Phase.
2, effectively save cost.The prefabricated plate production in post-cast strip and installation cost are low, and installation is quick, easy,
Strong operability；Closure construction in advance, the problem more than cleaning difficulty, recruitment before reducing post-cast strip closing.It is handled according to this engineering method
Basement post-pouring zone required cost: 1611.44 yuan (prefabricated and installation post-cast strip concrete expense: 365 yuan/m3 × (1.2m ×
0.6m × 0.08 × 6)=1261.44 yuan；The unilateral template installation in inside: 1 labour cost × 350 yuan/day=350 yuan), using this
Engineering method processing poured band of outer wall of basement amounts to expense and is.
, can be 427.6 yuan of direct saving expense from the point of view of a poured band of outer wall of basement, it in addition shortens the construction period up to 10 days
(conventional construction method spends the time: 1., which build 240 walls, needs 3 days, and point 3 masonry, building height daily by code requirement is
1.5m；2. cannot plaster immediately after building, 2 progress of plastering point need 3 days；3. can be applied after plastering mortar reaches intensity
Brush water-repellent paint, this area generally consider 5 days.And this engineering method install after directly can brush water-repellent paint, installation only need just
Calculate 1 day.To sum up save 10 days durations).
3, it improves quality and eliminates safe hidden trouble.It is anti-that outer wall of basement can be carried out in time after the completion of outer wall of basement construction
Water, outdoor backfilling of earthwork reduce the probability for generating structural cracks because of day and night temperature due to basement structure exposure for a long time, eliminate
Deep basal pit bring security risk.
4, the prefabricated plate in post-cast strip is able to achieve efficient, volume production.The routinely reserved setting of size substantially of post-cast strip size,
Efficient, volume production can be able to achieve using the prefabricated plate technique in post-cast strip.
In summary, the utility model avoids reinforcing bar rust in post-cast strip caused by the preceding infiltration of basement post-pouring zone closing
Erosion, basement ponding, improve construction quality, reduce engineering construction difficulty.Meanwhile the prefabricated plate in post-cast strip installs
After can carry out next procedure construction, reduce the contradiction between process, greatly accelerate speed of application, shorten the duration, be
Construction unit and unit in charge of construction all bring considerable economic benefit.
The utility model is suitable for the construction of skyscraper, large public building basement (garage) post-pouring belt of outer wall,
The basement engineering of backfilling of earthwork need to be carried out immediately suitable for that must stay to set post-cast strip but construct because of adjacent building, while being suitable for applying
Work narrow field, duration need to tightly carry out the interspersed engineering of the subsequent handlings such as indoor masonry.
