With the arrangement of the post-casting belt used in many structural projects, the construction quality of the post-casting belt directly affects the quality of the main structure project. During the construction stage of the main structure, if the construction of the post-casting belt is not well controlled, it will directly affect the construction progress , increase the construction cost, and seriously affect the construction quality of structural engineering
During the process of retaining the post-cast belt of the foundation floor, the lower opening of the vertical formwork often leaks seriously, and it is very troublesome to clean up, time-consuming and labor-intensive

[0014] (1) Concrete strips are poured at the lower opening
[0015] Such as figure 1 As shown, when the post-pouring belt 1 is left in place, the lower mouth of the vertical formwork, that is, the part below the lower mesh reinforcement, often has serious grout leakage, and the method of pouring plain concrete belts at the lower mouth can effectively prevent the grout leakage at the lower mouth. After the construction of the waterproof layer is completed, when the protective layer 1 of the waterproof layer is poured, the 50mm wide concrete strip 3 is poured with formwork, and the position is as follows: figure 2 As shown, the strength grade of the concrete strip is the same as that of the bottom slab concrete, and the position of the top surface of the concrete strip is controlled at the lower opening of the lower mesh under the foundation bottom slab.
[0016] (2) The spot welding of the vertical support reinforcement is firm
[0017] The vertical supporting steel bar 6 is...

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 [0001] The invention relates to a leak-proof grout method for post-pouring a base plate, which belongs to the field of construction engineering. Background technique [0002] For the cast-in-place integrated reinforced concrete structures of high-rise residential buildings, public buildings and super-long structures, post-cast belts are required due to construction reasons. Temporary belt-shaped joints play a role in digesting settlement shrinkage and deformation. According to engineering needs, after a certain period of time, concrete is poured to form a continuous and integral structure. With the application of the post-casting belt in many structural projects, the construction quality of the post-casting belt directly affects the quality of the main structure project. In the construction stage of the main structure, if the construction of the post-casting belt is not well controlled, it will directly affect the construction progress. , increase the constr...
