Abstract
The invention discloses a construction method for a basement floor post-cast strip waterproofing structure and belongs to the technical field of waterproofing of buildings. The construction method comprises the following steps: laying a main drain pipe and a branch drain pipe in a water filtering tank to a floor sump, fully laying graded broken stone in the water filtering tank to form a broken stone water filtering layer, arranging mortar stop blocks on two sides at the lower part of a post-cast strip, and mounting floor reinforcing bars; mounting mortar stop blocks on two sides at the upper part of the post-cast strip after mounting a post-cast strip side form; and pouring post-cast strip concrete after pouring floor concrete on two sides of the post-cast strip, and curing concrete under a strip-film heat and moisture preservation condition for not less than 14 days. The construction method provided by the invention can reduce water pressure of a basement floor, realizes the waterproofing function of the basement floor post-cast strip and guarantees the pouring quality of concrete.
Description
Technical field
The invention belongs to building waterproofing technique field, be specifically related to a kind of construction method of basement bottom plate rear pouring tape waterproof construction.
Background technology
In big basement structure construction, need to establish ater-casting to solve differential settlement and to reduce the problem of shrinkage stress, the structure design of ater-casting and construction technology can affect the construction quality of rear whole basement structure, even affect normal usage function.Present stage basement bottom plate rear pouring tape waterproof construction mainly to adopt to block up be main construction method, the construction measure of waterproofing course is set at the bottom of pre-embedded steel slab waterstop and plate in the soleplate, but still there is leakage scenarios in various degree in basement bottom plate rear pouring tape.
Summary of the invention
The object of the invention is to the technical problem for existing in existing basement bottom plate rear pouring tape construction method, a kind of construction method of basement bottom plate rear pouring tape waterproof construction is provided.
The construction method concrete steps of a kind of basement bottom plate rear pouring tape waterproof construction provided by the present invention are as follows:
(1) after foundation pad 6 has been constructed, drain header 5 and branch drain 7 to base plate sump is buried underground in drainage trap, be paved with graded broken stone in drainage trap after installation below ater-casting 2 and form rubble drainage layer 4, then on rubble drainage layer 4, lay plastic sheeting separation layer 9 along direction, ater-casting 2.
(2) before base plate lower floor reinforcement installation, in ater-casting, 2 liang of side lower parts arrange mortar block 8, are placed on by reinforcing bar in the groove of described mortar block 8, prevent concrete in basement bottom board 1 casting process from flowing in ater-casting 2, then install other baseplate reinforcing bar.
(3) install ater-casting side form, ater-casting side form 3 adopts dense mesh and cage of reinforcement to install, and dense mesh is placed on the concrete side of basement bottom board 1, and firm with tied silk colligation; Cage of reinforcement and base plate top reinforcement and base plate lower floor reinforcement welding are fixed, and install mortar block 8 at top reinforcement mesh sheet ater-casting upper position.
(4) build both sides, ater-casting underplate concrete, build both sides, ater-casting concrete and vibration compacting by the requirement of underplate concrete job specfication, clear up the loose concrete in both sides, ater-casting in time and rinse well.
(5) until basement bottom board concrete shrinkage and building settlement basicly stable and carry out ater-casting concreting after reaching the designing requirement time, foreign material before building in cleaning ater-casting 2 and dismounting are positioned at the mortar block of ater-casting 2 upper position, inspection adjustment is carried out to reinforcing bar, water water-wet, adopt the concreting ater-casting of admixture micro-expanding agent, abundant vibration compacting, take curing concrete under band film heat and moisture preserving condition, curing time is no less than 14 days.
The present invention has following technical characterstic:
1, late poured band structure is simple, constructability operation and quality control;
2, reduce basement bottom board water pressure, realize basement bottom plate rear pouring tape water-proof function;
3, in ater-casting without ponding, concrete pouring quality is guaranteed;
4, adopt rubble drainage layer to substitute ater-casting bottom reinforcement bars concrete and strengthen structure, cancel coil waterproof layer, steel plate water stopper, saved cost, accelerating construction progress.
Accompanying drawing explanation
Fig. 1 is the ater-casting waterproof construction schematic diagram after the inventive method construction.
In figure: 1: basement bottom board; 2: ater-casting; 3: ater-casting side form; 4: rubble drainage layer; 5: drain header; 6: foundation pad; 7: branch drain; 8: mortar block; 9: plastic sheeting separation layer.
Detailed description of the invention
The construction sequence of basement bottom plate rear pouring tape waterproof construction provided by the present invention is specific as follows:
1, after foundation pad 6 has been constructed, drain header 5 and branch drain 7 to base plate sump is buried underground in drainage trap, drain header 5 first half is provided with the drain hole of φ 8-10mm, be paved with graded broken stone after installation in basement bottom plate rear pouring tape bottom and form rubble drainage layer 4, macadam gradating is preferably 10-31.5; Finally on rubble drainage layer, spread the wide 1.5m of one deck thick 0.5mm plastic sheeting separation layer 9 along direction, ater-casting 2 sky.
2, before base plate steel bar binding, mortar block 8 is placed at ater-casting, both sides lower position, bottom layer of the reinforcing steel mesh sheet lower floor reinforcing bar is placed in the groove of mortar block 8, prevents concrete in basement bottom board 1 casting process from flowing in ater-casting 2, then other baseplate reinforcing bars are installed.
3, ater-casting side form 3 adopts dense mesh and cage of reinforcement to install, dense mesh is placed on basement bottom board 1 concrete side, and it is firm with tied silk colligation, cage of reinforcement and base plate top reinforcement and base plate lower floor reinforcement welding are fixed, and install mortar block 8 at top reinforcement mesh sheet ater-casting upper position.
4, build both sides, ater-casting 2 basement bottom board 1 concrete and vibration compacting by underplate concrete constructure scheme and code requirement, clear up the loose concrete in both sides, ater-casting 2 in time and rinse well.
5, treat basement bottom board 1 concrete shrinkage and building settlement basicly stable, and can ater-casting 2 concreting be carried out after reaching the designing requirement time; Foreign material before building in cleaning ater-casting 2 and dismounting are positioned at the mortar block 8 on top, ater-casting 2, and watering, it is wetting to rinse, and carry out inspection adjustment to reinforcing bar; Adopt the concreting ater-casting 2 of admixture micro-expanding agent, abundant vibration compacting; Take curing concrete under band film heat and moisture preserving condition, curing time is no less than 14 days.
