Description

Building with brick-concrete structure lifts increasing layer method
Technical field
The present invention relates to a kind of building building technology, especially a kind of side using lifting implementation existing building increasing layer Method, specifically a kind of building with brick-concrete structure lifting increasing layer method.
Background technology
Existing building increasing layer is protection land resource, expands usable floor area, and lifting uses the effective ways of function.Building Building thing top increasing layer needs to remove the insulation of former roofing and waterproof layer, in the new insulation of the top construction of newly-increased structure sheaf and prevents Water layer, easily cause the waste of resource;Meanwhile increasing layer makes the increase of original structure load, the vertical member bearing capacity of building bottom is not Foot is, it is necessary to consolidation process.
The content of the invention
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of building with brick-concrete structure lifts increasing layer Method, after building with brick-concrete structure is lifted, with underground increasing layer more than the ground of bottom, expand building usable floor area.
To achieve the above object, the present invention uses following technical proposals:
Building with brick-concrete structure lifts increasing layer method, comprises the following steps:
Step 1:The earthwork of building bottom is excavated, exposes strip footing;
Step 2:Transform beams are laid inside and outside the building masonry wall of strip footing top surface, by building masonry wall It is sandwiched between transform beams, the building masonry wall in transform beams bottom penetrates pull rope;
Step 3:Exchange pillar is laid through strip footing, underpins the hard soil layer that column bottom is supported on strip footing bottom On;
Step 4:Traction enhancement device is installed at the top of exchange pillar, pull rope is connected with traction enhancement device;
Step 5:Traction enhancement device is set to tighten up pull rope, by the connection of transform beams bottom building masonry wall and strip footing Place is blocked;
Step 6:Traction enhancement device is worked on, and building is promoted into setting position;
Step 7:The earthwork below strip footing is excavated, forms foundation ditch;
Step 8:Basement bottom board is built in foundation ditch bottom pour mold, basement wall and building are poured immediately below building masonry wall One layer of wall;
Step 9:Removal traction enhancement device and pull rope, exchange pillar and transform beams are removed, carry out basement and building The construction of first floor plate;
Step 10:The earthwork in the external foundation ditch of basement wall is backfilled, recovers ground.
Preferably, in the step 2, along the connecting key for underpining distance between girders setpoint distance setting passing through building wall, lead Messenger passes through along connecting key in the building wall body of connecting key bottom.
Preferably, the vertical building masonry wall of the connecting key is laid;Easily lay and implement, more save connecting key material Material, traction enhancement process are relatively reliable.
In the step 3, exchange pillar is laid in inside and outside building masonry wall, and the laying position of exchange pillar and pull rope Put corresponding.
The traction enhancement device is hoist engine or Lift-slab machine.
The pull rope is steel wire rope.
The step 4 concretely comprises the following steps:Hoist engine or Lift-slab machine are installed at the top of exchange pillar, pull rope is penetrated into elevator The drum barrel of machine or Lift-slab machine.
The step 5 concretely comprises the following steps:Hoist engine or Lift-slab machine are started, after pull rope is tightened up painstakingly, closes down elevator Machine or Lift-slab machine, the junction of transform beams bottom building masonry wall and strip footing is blocked.
The depth of earth excavation is equal to the floor height of one layer or two layers basement in the step 7.
The present invention operation principle be:
By setting transform beams to clamp building masonry wall, and connecting key is laid between transform beams, penetrated by connecting key Pull rope, the instrument as lifting building;Exchange pillar is laid in building masonry wall both sides, is carried by exchange pillar installation traction Device is risen, after building is promoted into setting position by traction enhancement device after being connected with pull rope, under earth excavation construction ground Room and floor building, existing building increasing layer is realized using lifting.
Beneficial effects of the present invention are:
Method of the invention using jacking realizes frame structure building and adds layer and set up basement, avoids roofing and prevents Water and the repetition construction of heat-insulation layer and the reinforcing of infrastructure.
The method that the present invention is lifted reduces the carrying of cushion block compared with jacking method and resting for process of jacking (jacked Cheng Zhong, the stroke of a jack, about 20cm are often risen to, cushion block is installed with regard to that need to rest).
In addition, lifting process building is walked along lifting circuit, it is not susceptible to offset, process is more easy to control, economy effect It is beneficial notable.

Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
Embodiment:
By three layer three exemplified by the building of brick mix structure strip footing, Fig. 1 and Fig. 2 build for original brick mix structure before lifting The schematic diagram of thing is built, the building masonry wall 1 is supported in the basic bottom of bearing stratum 4 by strip footing 2, mixed by 3 layers between wall 1 Coagulate native beam slab 3 to connect, the basic bottom of bearing stratum 4 is supported on hard soil layer 5.
As shown in Fig. 3-Figure 14, by three layer three exemplified by the building of brick mix structure strip footing, building lifting increasing layer Method includes procedure below:
