Description

Construction method for pre-closing post-pouring zone of external wall of ground warehouse without bricking

Technical Field

The invention relates to the technical field of concrete pouring, in particular to a construction method for pre-closing a post-pouring zone of an external wall of a ground warehouse without bricking.

Background

In many residential engineering at present, many post-cast strips of design drawing ground storehouse are subsided post-cast strips, require all to need main part capping after 2 months and just can pour post-cast strip concrete, have two influences under the circumstances like this: the first post-pouring zone and the post-pouring zone are not closed, the outer wall cannot be constructed in a waterproof manner, backfilling cannot be carried out, and the second post-pouring zone and the post-pouring zone are not backfilled for a long time, so that the danger source of the foundation pit exists for a long time, and the post-pouring zone of the outer wall of the ground warehouse needs to be closed in advance for inserting other and working procedures in advance to eliminate the danger source. If the post-cast strip sealing measures are used for bricking, the bricking engineering is complicated, plastering is performed on the outer side, and the outer wall cannot be immediately inserted into the construction for one day after the plastering is finished (the post-working is performed), so that analysis is performed, and the economic rationality is poor.

Disclosure of Invention

The invention aims to overcome the defects, and provides a construction method for sealing post-cast strips of an external wall of a ground warehouse in advance without bricking, which adopts a precast slab hoisting mode to seal, so that the construction of the procedures of external wall waterproofing and fertilizer groove backfilling can be inserted in advance, the low-efficiency and poor-strength masonry process is solved, the construction progress is integrally accelerated, the cost is saved, and the quality is improved.

In order to achieve the above object, the present invention is achieved by:

a construction method for pre-closing post-pouring zone of external wall of ground warehouse without brick laying comprises

Step 1, construction of an outer wall post-cast strip precast slab:

step 1.1, prefabricating an outer wall post-pouring belt prefabricated plate;

step 1.2, hanging wires;

step 1.3, hoisting;

step 1.4, reinforcing;

step 1.5, leveling waterproof mortar at the splicing position of the plates;

step 1.6, hoisting the subsequent precast slab

Step 1.7, leveling after hoisting is finished;

step 1.8, smearing an arc at the internal corner;

step 1.9, waterproof coiled materials;

step 1.10, sticking an extruded sheet;

step 1.11, backfilling soil;

step 2, sealing and blocking the basement outer wall post-pouring belt by adopting a concrete precast slab with the thickness of 100:500:1200: 1200mmC 40;

step 2.1, sequentially upwards discharging from a foundation slab, wherein the size of the uppermost precast slab is based on the actual measurement size in the field;

step 3, hanging rings ∅ on the prefabricated plates are cut off after the prefabricated plates are hung, and then the prefabricated plates are hung after leveling is carried out by waterproof mortar;

step 4, connecting the concrete precast slabs with the basement outer wall, and tying the concrete precast slabs with the horizontal ribs of the basement outer wall by utilizing ∅ steel bars on the concrete precast slabs;

step 5, paving waterproof mortar between the precast slabs for leveling;

step 6, the joint of the concrete precast slab and the basement outer wall is smeared into an oblique angle of 45 degrees by waterproof mortar;

and 7, paving waterproof coiled materials at the post-pouring belt, and expanding prefabricated plates by 1000mm on two sides.

By adopting the steps, the construction method is capable of inserting the waterproof construction of the external wall and the backfilling process of the fertilizer groove in advance on the premise that the post-cast strip of the external wall cannot be poured, and solves the problems of low efficiency and poor strength of masonry, thereby accelerating the construction progress, saving the cost and improving the quality.
