Description
Technical field
The utility model belongs to building structure technology field, and in particular to a kind of basement basic unit mortar leakage prevention post-cast strip knot
Structure.
Background technology
For large-sized reinforced concrete cast-in-place structural, when concrete base layer is poured into a mould, Temperature Joint, subsiding crack are reserved
Deng movement joint (being referred to as post-cast strip in construction)；Post-cast strip is blocked after concrete base layer stabilization, then with concrete, makes deformation
Seam both sides connect with concrete base layer structure, to ensure the globality of concrete base layer and integrality.With concrete knot
Structure engineering development, the implementation of more big construction items, the utilization of post-cast strip are more and more frequent；So that the construction of post-cast strip
Quality will directly affect the security performance of main structural engineering.During main structure construction, if not controlling post empiricism matter strictly
Amount, construction speed will be influenceed, increase construction cost, or even cause Structural Engineering quality dissatisfaction.In concrete base layer post-cast strip
In reservation procedure, often spillage is serious by post-cast strip both sides Xia Kou, and cleaning is very cumbersome, i.e., time-consuming and take a lot of work, and traditional post-cast strip
Section be quadrangle, in later stage casting process, concrete in post-cast strip can not good contract with both sides concrete base layer
Close, cause easy leak, while have an effect on total intensity.
Utility model content
Based on this, in view of the above-mentioned problems, the utility model proposes a kind of basement basic unit mortar leakage prevention late poured band structure, it is not
Meeting spillage, good waterproof performance, and structural strength is high.

Sandstone packed layer, concrete water-proof layer and the concrete base layer of secondary setting；The concrete water-proof layer is provided with water leg, described
Concrete base layer is provided with the post-cast strip corresponding with the water leg, and the both sides of the post-cast strip are laciniation；It is described
Water leg and the joining place of post-cast strip are provided with concrete banquette.
In work progress, after the completion of sandstone packed layer and the construction of concrete water-proof layer, in the water leg of concrete water-proof layer
Both sides cast concrete banquette, after concrete banquette drying distortions are stable, pour into a mould concrete base layer, pour into a mould concrete base layer
When, reserve post-cast strip using zigzag concrete baffle plate well prepared in advance, due to the plugging action of concrete banquette, after pour
Band two bottom sides are not in spillage phenomenon, have saved clearance time, that is, have saved the cost of labor of cleaning, accelerated construction again
Progress, shorten the duration；After concrete base layer drying distortions are stable, zigzag concrete baffle plate is removed, is poured into post-cast strip
Concrete is noted, because post-cast strip both sides are zigzag, during compacted concrete, the both sides of concrete and post-cast strip can be filled
Divide stress, the mixed mud in post-cast strip is compacted closer, and make the concrete and both sides concrete base layer contract in post-cast strip
Conjunction is closer, makes total intensity higher, and water proofing property is more preferable.
As further improvement of the utility model, the angle of each slot is 120 degree -150 in the zigzag structure
Degree.
Slot is too small, can influence agreeing with for post-cast strip inner concrete and both sides concrete base layer on the contrary, it is necessary to assure slot
It is sufficiently large, it is advisable with 120 degree of -150 degree.
It is provided with along its length as further improvement of the utility model, on the concrete banquette multiple flexible
Stitch, the spacing between adjacent two expansion joint is 45m-55m.Temperature deformation influences banquette quality when avoiding concrete banquette long.
As further improvement of the utility model, the surface of the laciniation is adhesive with waterproofing protection film.
As further improvement of the utility model, the post-cast strip top open part is provided with sealing plate.Sealing plate is set
Put, avoid debris from falling into post-cast strip, and play waterproof action.
As further improvement of the utility model, reinforcement is equipped with the concrete base layer and post-cast strip.Add
The setting increase structural strength of strengthening tendons.
The beneficial effects of the utility model are：
(1) it is provided by the utility model go out basement basic unit mortar leakage prevention late poured band structure, its will not spillage, good waterproof performance,
And structural strength is high；
(2) because the plugging action of concrete banquette, post-cast strip two bottom sides are not in spillage phenomenon, cleaning has been saved
Time, that is, the cost of labor of cleaning is saved, construction speed has been accelerated again, shortens the duration；
(3) because post-cast strip both sides are zigzag, during compacted concrete, the both sides of concrete and post-cast strip can
Abundant stress, the mixed mud in post-cast strip is compacted closer, and make the concrete and both sides concrete base layer in post-cast strip
Agree with more closely, make total intensity higher, and water proofing property is more preferable；
(4) by rationally designing the size of post-cast strip both sides slot, post-cast strip inner concrete and both sides concrete base layer are made
Preferably agree with, enhancing structure strength and stability.
