Foundation beam-slab construction method

Abstract

The invention discloses a foundation beam-slab construction method. The methods comprises the following steps that a plain soil backfilling method or a foundation excavation method is used for constructing to obtain a foundation soil layer; a cushion layer is constructed on the foundation soil layer, and leveling is carried out; a waterproof layer is constructed on the cushion layer after the leveling; a plurality of crisscross waterproof protective layers extending along the strike of a foundation beam are constructed on the position, where the foundation beam needs to be constructed, of thewaterproof layer; beam mould forming strip groups which extend in the length direction of the waterproof protective layers and are used for forming a foundation beam mould are arranged on waterproof protective layers; geotechnical cloth is laid in each filling grid formed by surrounding of the beam mould forming strip groups, and the periphery of the geotechnical cloth in each filling grid extendsto the top portions of beam mould forming strips which surround the filling grids and is fixed; foamed concrete is poured in the geotechnical cloth of each filling grid to form a base plate mould; the beam mould forming strip groups are removed; and the reinforced concrete is poured on the surface of the formed foundation beam mould and the upper surface of the foundation plate to obtain the foundation beam-slab.

Description

technical field [0001] The invention relates to the field of building beam and slab construction, in particular, to a foundation beam and slab construction method. Background technique [0002] In the prior art, when constructing building foundation beams and slabs, the following steps are mainly included: 1. Backfilling and compacting plain soil layer by layer; Building brick membrane; 4. Artificial backfilling and compaction of plain soil around the brick membrane; 5. Pouring the fine stone concrete cushion at the bottom of the large panel; 6. Construction of mortar leveling layer and plastering of brick membrane; 7. Construction of waterproof membrane; 8. Laying geotextile; 9. Construction of waterproof protective layer; 10. Construction of steel plate and steel bar; 11. Pouring concrete. [0003] Problems and shortcoming existing in prior art scheme: [0004] ① There are many processes and a long construction period; the existing technology has a total of 11 processes,...
