Description
Technical field
The present invention relates to the advanced enclosed construction of poured band of outer wall of basement and construction method, belong to industry and civil buildings master
Outer wall of basement and post empiricism field in body structure, be mainly used in advanced protection and the later stage of poured band of outer wall of basement
Post-cast strip concrete pouring construction in.
Background technology
In the construction of outer wall of basement, due to single construction body of wall length restriction and construction in Deformation control want
Ask, outer wall of basement needs arrange post-cast strip.The construction operation carried out before poured band of outer wall of basement is closed is not only
There is potential safety hazard, and foreign material, rainwater are easily accessible in basement with construction water before post-cast strip is closed, and affect post-cast strip
Pouring quality and normal construction.Poured band of outer wall of basement concreting time interval is longer, it is generally required to underground body junction
Just carry out the pouring construction of post-cast strip after structure construction, therefore if do not carried out the advanced closing of post-cast strip, outdoor backfill can be made
Operation can not be carried out, and installs the place providing necessary also can not to agent structure and equipment.
At present poured band of outer wall of basement is closed the concrete prefabricated closing plate of employing in advance and is constructed, its enclosed construction and
Construction method document " card slot type formwork construction technology outside poured band of outer wall of basement (and " construction technology ", 2015,44
(23), disclosed in: 85-87) ", which solve the gear soil antiseepage problem of the advanced enclosed construction in post-cast strip, but still there are the following problems:
(1) enclosed construction is assembled by polylith precoated plate, easily tilts, shifts in construction, closes when causing later stage post-cast strip to pour
Structure serious displacement impact construction under malformation；(2) enclosed construction itself does not have barrier properties, becomes due to construction in outside
When shape is bigger, waterproof layer tears and destroys, the waterproof of enclosed construction can not work；(3) outer wall of basement and post-cast strip coagulation
It is complicated that soil pours formwork.
Summary of the invention
Present invention aims to the technical problem that the advanced enclosed construction of existing poured band of outer wall of basement exists, carry
Go out the advanced enclosed construction in a kind of post-cast strip and construction method, use band draw-in groove and the closing plate on-site consolidation of watertight rubber bar
And it is linked as entirety by dowel, steel plate for sealing water and accessory structure are set on closing plate simultaneously, reach sealing, gear soil, formwork
Deng technique effect.
In order to realize above-mentioned technical purpose, present invention employs techniques below scheme:
A kind of advanced enclosed construction of poured band of outer wall of basement, it is characterised in that include closing plate, brick setting overcoat, waterproof
Layer, mortar levelling layer, junction steel plate, steel plate for sealing water, connection peg, described brick setting overcoat builds by laying bricks or stones in campshed side within the walls,
Outside lower outdoor wall, described waterproof layer is arranged on brick setting overcoat, arranges mortar levelling layer, described junction steel plate outside it
Being provided with reinforcing bar through hole, the horizontal bar of framework of steel reinforcement is through reinforcing bar through hole and is welded on junction steel plate, described closing plate
Upper and lower side raised item and groove is nested with one another and is linked as entirety, described junction steel plate one end by dowel in vertical direction
Snap in the draw-in groove closed on plate, and filling flexible sealing material.

Utilize the method that the advanced enclosed construction of above-mentioned poured band of outer wall of basement carries out poured band of outer wall of basement construction, its
Being characterised by, construction procedure is as follows:
Step one, brick setting overcoat building construction: along outer wall of basement build by laying bricks or stones with the outside of post-cast strip together with brick setting protection
Layer；
Step 2, construction of waterproof layer: brick setting overcoat surface base cleaning is clean, smooth, the uniform application cold end in basic unit
Seed oil, pastes waterproof roll to form waterproof layer；
Step 3, mortar levelling layer are constructed: one layer of mortar levelling layer of constructing on waterproof layer；
Step 4, closing plate are installed: prefabricated closing plate lifting put in place, and dowel passes closes the pvc pipe reserved on plate,
Closing plate by bolt by every layer to fasten, the bolt after fastening is placed in cavity, and gripper shoe is pasted one layer of isolating membrane；
Step 5, tie with reinforcing bar and junction steel plate are fixed: the framework of steel reinforcement of colligation outer wall of basement, at outer wall of basement and
The intersection of post-cast strip, the main muscle of horizontal full-length through the reserving hole on junction steel plate, junction steel plate is welded with steel plate for sealing water and
Connecting peg, junction steel plate one end snaps in groove, and filling flexible sealing material, pre-through on junction steel plate minor face of screw rod
Hole of boxing out is welded on framework of steel reinforcement；
Step 6, outer wall of basement inner side template are installed and casting concrete: outer wall of basement inner side template uses single side formwork
Method is installed, and adopts and is bolted on screw rod, and casting concrete；
Step 7, backfill layer construction: after outer wall of basement concrete strength reaches requirement, brick setting overcoat and campshed wall it
Between fill backfill layer, and remove outer wall of basement inner side template；
Step 8, post-cast strip inner side template are installed: main structure construction is complete and after stabilization, carries out post empiricism, clearly
Except the framework of steel reinforcement surface rusty stain of post-cast strip, post-cast strip inner side template is installed；
Step 9, post-cast strip concreting: pour the concrete of post-cast strip, and vibration compacting；
Step 10, post-cast strip concrete curing form removal: after the concrete curing of post-cast strip, intensity reaches strength of mould stripping, waters after dismounting
Band inner side template.
Further, in step 8, inner side template is made by plywood, uses level stupefied and perpendicular stupefied as shuttering supporting bone
Frame, will erect stupefied being anchored on junction steel plate minor face by fastening bolt and screw rod.
The invention have the characteristics that and beneficial effect:
(1) band draw-in groove and the closing plate of watertight rubber bar are used and by the fastening of dowel, it is ensured that enclosed construction forms gear soil
Support entirety, and itself there is sealing barrier properties, be prevented effectively from the outer muddy water of wall and infiltrate on the impact constructed；
(2) gripper shoe at plate two ends and outside brick setting overcoat (including waterproof layer and mortar levelling layer) are closed outside basement
Using as outboard template during wall concreting, after construction completes, soil pressure and the hydraulic pressure of the soil that fillered after closing plate pass
Passing on outer wall of basement, the existence of isolating membrane simultaneously ensures can be certainly in vertical direction between enclosed construction and outer wall of basement
Deformed by dislocation；
(3) junction steel plate is provided with steel plate for sealing water and connects peg, it is ensured that strengthen basement while outer wall of basement barrier properties
Bonding strength between exterior wall and post-cast strip, junction steel plate snaps in the interior also filling flexible sealing material of draw-in groove of enclosed construction, enters one
Step improves the impermeability of post-cast strip；
(4) minor face of junction steel plate is provided with fixing link bolt hole and the screw rod of alter-pouring strips mould plate, facilitates propping up of alter-pouring strips mould plate
If.
