Brick-concrete structure building lifting add-layer method

Abstract

The invention discloses a brick-concrete structure building lifting add-layer method comprising the following steps: excavating building bottom earthwork so as to expose the bar shaped base; respectively arranging a transfer girder on the inner side and outer side of the building wall, and penetrating traction ropes into the building wall on the bottom of the transfer girders; penetrating the bar shaped base so as to arrange transfer columns, wherein the bottoms of the transfer columns support in the hard soil layer under the bar shaped base; arranging a traction lifting device on the top of the transfer column; cutting off the connecting portion between the transfer girder bottom building wall and the bar shaped base; using the traction lifting device to lift the building up to a set position; excavating earthwork so as to form a ground pit; casting a basement base plate on the bottom of the ground pit, and casting basement walls and the building first floor wall; constructing the basement and the building first floor board; backfilling the earthwork outside the basement walls in the ground pit, and recovering the ground. The lifting method can realize framework structure building add-layer and basement adding, can prevent roofing waterproof and heat-insulation layer repetition construction, and can reinforce ground floor members.

Description

technical field [0001] The invention relates to a civil construction technology, in particular to a method for increasing the storey of an existing building by means of lifting, specifically a method for increasing the storey of a brick-concrete structure building. Background technique [0002] Adding floors to existing buildings is an effective way to protect land resources, expand the use area, and improve use functions. Adding a layer on the top of a building requires removing the insulation and waterproof layer of the original roof, and constructing a new insulation and waterproof layer on the top of the newly added structure layer, which is likely to cause waste of resources; The vertical members at the bottom have insufficient bearing capacity and need to be reinforced. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of brick-concrete structure building promotion and...
