Abstract
The invention discloses a mortar leakage resistant method for a foundation slab late poured band and belongs to the construction engineering field. The mortar leakage resistant method for the foundation slab late poured band is concretely as follows: (1) a plain concrete belt is poured at a lower opening; (2) a vertical support reinforcing steel bar is made a firm spot welding; (3) a steel screen is bound; (4) a square timber is positioned at the top and is firmly bound with the vertical support reinforcing steel bar and the slab reinforcing steel bar. In the building structure that the mortar leakage resistant method for the foundation slab late poured band of the invention is practically applied almost has no mortar leakage phenomenon; the invention has remarkable mortar leakage resistant effect, reduces the repetitive working and improves the construction quality.
Description
Technical field
The present invention relates to a kind of foundation bedplate post-pouring strip mud-leakage preventing method, belong to building engineering field.
Background technology
Cast-in-place whole reinforced concrete structure for high residential building, public building and the super-long structural of height structure, because construction reason need be provided with the ater-casting, the ater-casting is meant in cast-in-place whole reinforced concrete structure, only the provisional band shape of retaining in construction period is stitched, play the effect of digestion sedimentation shrinkage strain, according to requirement of engineering, behind the reservation certain hour, again with the closely knit structure that becomes continuous integral body of concreting.Along with the utilization in the numerous Structural Engineerings of being arranged in of ater-casting, the construction quality of ater-casting directly influences the quality of main structural engineering, in the main structure construction stage, as bad to the ater-casting construction control, to directly influence construction speed, increase construction cost, seriously influence the Structural Engineering construction quality.In sole plate post-poured strip indwelling process, often spillage is serious for vertical template end opening, and cleaning is got up and bothered very much time-consuming taking a lot of work.
Summary of the invention
In order to solve the deficiencies in the prior art, can prevent the foundation bedplate post-pouring strip mud-leakage preventing method that a large amount of spillages occur when the object of the present invention is to provide a kind of the construction.
In order to realize the foregoing invention purpose, the present invention is achieved through the following technical solutions: foundation bedplate post-pouring strip mud-leakage preventing method of the present invention is characterized in that:
(1), builds the plain concrete band at end opening, be specially, after construction of waterproof layer is finished, when building the waterproofing course topping, formwork is built the wide concrete belt of 50mm, the strength grade of concrete belt is with the underplate concrete strength grade, and the concrete belt top side location is controlled at the end opening of sole plate lower net plate lower floor reinforcing bar;
(2), vertical bearing bar spot welding is firm, be specially, after the base plate reinforcing bar binding finishes, can carry out the spot welding work of vertical bearing bar, in ater-casting indwelling place, the top is along ater-casting length direction backguy, the below begins perpendicular to reinforcing bar on the limit of ater-casting length direction from base plate near concrete belt, and the rebar spacing perpendicular to the ater-casting length direction is suitably adjusted every 300mm or in according to base plate, place a bearing bar, and firm with the spot welding of base plate reinforcing bar;
(3), the colligation expanded metal lath, be specially, expanded metal lath will be cut off at the position that runs into the base plate reinforcing bar, making that the net sheet is suitable for reading can be equal with the underplate concrete face, end opening reaches the waterproofing course topping, opening part connects with the metal binding wire colligation; Expanded metal lath is firm with base plate reinforcing bar, bearing bar colligation respectively; Need the one side of concreting to place level at expanded metal lath, push down expanded metal lath to reinforcement, and firm with base plate reinforcing bar and vertical bearing bar colligation;
(4), place the lumps of wood, firm with vertical bearing bar and base plate reinforcing bar binding at the top.
Aforesaid foundation bedplate post-pouring strip mud-leakage preventing method is characterized in that the plain concrete band builds shaping with the waterproofing course topping.

The specific embodiment
Specifying in conjunction with content of the present invention provides following example:
(1), builds the plain concrete band at end opening
As shown in Figure 1, when keep somewhere ater-casting 1, vertical template end opening, that is, the lower net plate reinforcing bar is with the lower part, and often spillage is serious, and the method that employing is built the plain concrete band at end opening can effectively prevent the end opening spillage.After construction of waterproof layer is finished; when building waterproofing course topping 1, formwork is built the wide concrete belt 3 of 50mm, and the position as shown in Figure 2; the strength grade of concrete belt is with the underplate concrete strength grade, and the concrete belt top side location is controlled at the end opening of sole plate lower net plate lower floor reinforcing bar.
(2), vertical bearing bar spot welding is firm
Vertical bearing bar 6 is expanded metal lath 7 topmost support keels, and is reliable for guaranteeing its firm supporting, adopts spot welding mode and 4 welding of base plate reinforcing bar.
After 4 colligations of base plate reinforcing bar finish, can carry out the spot welding work of vertical bearing bar 6.Adopt Φ 18 reinforcing bars, highly be the below on earth, the top deducts protective layer thickness to underplate concrete plate face.In ater-casting indwelling place, the top is along ater-casting length direction backguy, the below is near concrete belt, from base plate, begin perpendicular to reinforcing bar on the limit of ater-casting length direction, suitably adjust perpendicular to the rebar spacing of ater-casting 1 length direction every 300mm or in according to base plate, place a bearing bar 6, and firm with 4 spot welding of base plate reinforcing bar.
(3), colligation expanded metal lath
After bearing bar 6 welds, colligation expanded metal lath 7.To note during colligation following some:
(a) expanded metal lath 7 will be cut off at the position that runs into base plate reinforcing bar 4, and making that the net sheet is suitable for reading can the base slab concrete surface, and end opening reaches fish tail and waterproof layer 2.Opening part connects with metal binding wire (not shown) colligation.
(b) expanded metal lath 7 is firm with base plate reinforcing bar 4, bearing bar 6 colligations respectively, and especially with the position of base plate reinforcing bar 4 handing-over, colligation must be solid and reliable.
(c) with reference to Fig. 3, cut off the part perk up and down for preventing expanded metal lath 7, want the one side of concreting to place level at expanded metal lath 7 to reinforcement 8, push down expanded metal lath 7, and firm with base plate reinforcing bar 4 and 6 colligations of vertical bearing bar.
(4), as shown in Figure 3, place the lumps of wood 5 at the top, firm with vertical bearing bar 6 and 4 colligations of base plate reinforcing bar.
Actual effect: use in the engineering construction of the present invention, owing to adopted above measure, almost do not have the spillage phenomenon in the ater-casting of indwelling, anti-spillage effect is very obvious.
Below announced the present invention with preferred embodiment, so it is not to be used to limit the present invention, and all technical schemes of taking to be equal to replacement or equivalent transformation acquisition all drop within protection scope of the present invention.
