The invention relates to the field of house construction, and provides a construction method for impermeability leakage prevention of a secondary structure aiming at the problem that an impermeable effect of a secondary structure is reduced because a waterproof layer easily falls off. The technical solution is as follows: the method comprises the following steps: step 1, building a reinforced barframe; step 2, building a casting template; step 3, pouring impermeable concrete; step 4, disassembling a casting template after the impermeable concrete is initially settled; and step 5, sprinkling water for curing, wherein the impermeable concrete comprises the following components, in parts by mass: 100 parts of Portland cement, 300-400 parts of coarse aggregate, 200-250 parts of fine aggregate, 100-150 parts of a nano filler, 30-50 parts of an adhesive, and 90-110 parts of water. According to the method provided by the invention, the nano filler is added into the impermeable concrete to fill gaps and fine pores in the concrete structure, the adhesive fills crack fine pores in the concrete structure, so that the concrete structure is very compact, the impermeability of the concrete structure is improved, even without addition of a waterproof layer, the impermeable effect is better and more stable, and the construction is more convenient.

The invention discloses a connecting structure of a floor slab and wallboards and a construction method of the connecting structure, relates to the technical field of house construction, and solves the problem that the connecting stability of the fabricated wallboards and the floor slab is poor. The connecting structure of the floor slab and the wallboards comprises the floor slab, the prefabricated upper wallboard and the prefabricated lower wallboard, a positioning piece is arranged on the upper end face of the floor slab, the bottom of the upper wallboard is provided with a positioning groove allowing the positioning piece to be inserted therein; and the top of the lower wallboard is provided with a fixing piece pre-buried in the lower wallboard and an adjusting piece movably arranged on the fixing piece in the vertical direction, the bottom of the floor slab is provided with a mounting groove allowing the upper end of the adjusting piece to be inserted therein, a vertically-arranged hollow pipe is mounted at the inner part of the floor slab, the lower end of the hollow pipe communicates with the interior of the mounting groove, the upper end of the hollow pipe communicates withthe positioning groove, a partition plate for enclosing the top sections of the lower wallboard and the floor slab is arranged between the lower wallboard and the floor slab, a grouting hole is formed in the partition plate, and an exhaust hole which communicating with the interior of the positioning groove is formed in the bottom of the upper wallboard. According to the connecting structure of the floor slab and the wallboards and the construction method of the connecting structure, the connection stability of the fabricated wallboards and the floor slab can be improved.
