Basement reconstruction structure with raft foundation building
Technical field
The present invention relates to a kind of Basement reconstruction method, in particular to a kind of Basement reconstruction with raft foundation building Structure.
Background technique
With the development of the city, parking difficulty becomes the problem of puzzlement common people.It is necessary to have transformation condition to some Building is transformed, and resets basement.For band raft foundation building, Basement reconstruction structure is due in raft plate base Stake is disposed below in plinth, and stake spacing is relatively close, and stake spacing is generally between 1.8~2.5mm, and these stakes are main vertical How load-carrying member can ensure that the safety of building and can ensure that the use function of basement, be engineering staff's class to be faced Topic.
Summary of the invention
The present invention is to provide a kind of Basement reconstruction structure with raft foundation building, during solving Basement reconstruction The problem of safety.
The present invention during Basement reconstruction of building using original as basement bearing column, and removably under Room site portion stake carries out reinforcing to original stake and forms bearing column, bearing column and original for the situation that original dowel section area is inadequate Have and effective connection is carried out using dedicated connecting structure between stake.It is logical that original stake and concrete floor contact site easily become infiltration Road carries out waterproof using watertight rubber ring.
Bearing column is the cylinder after original stake is reinforced, the original half 120~300mm of path length of stake of bearing column radius ratio, i.e., It is 120~300mm that annular concrete width is reinforced in bearing column, and the principal rod that annular concrete is reinforced in bearing column uses diameter For the reinforcing bar of 22~25mm, adjacent load intercolumniation is 3.5~6m;The total sectional area of bearing column is always cut with former all piles after reinforcing Area is identical or difference is less than 10%;Basement bottom board sets with a thickness of 400~550mm, basement bottom board in bearing column position Shearing resistance muscle is set, shearing resistance muscle diameter uses 32~35mm, and shearing resistance muscle shape is split heads shape.Original outer surface is set in concrete floor Watertight rubber ring is set, it is that ring seal slot is arranged along original outer surface in the middle part of concrete floor that position, which is arranged, in watertight rubber ring, Ring seal slot 3~5mm of indent, ring seal slot are embedded in watertight rubber ring;Polyurethane water-proof sand is set above concrete floor Slurry, polyurethane water-proof mortar thickness are 15~25mm.
When original stake is hollow shell pill, annular concrete is reinforced in bearing column with original connecting structure using as follows: Hollow shell pill is inserted into joint bar, and joint bar hole is arranged in hollow shell pill, and joint bar hole is arranged symmetrically, and joint bar bore dia is 28~31mm, joint bar Diameter is 25~28mm;If reinforcing annular concrete section width is less than or equal to 150mm, joint bar combines to form cross, such as Fruit reinforces ring section width and is greater than 150mm, and joint bar combines to form M shape;Joint bar is evenly arranged along stake length direction, joint bar edge The spacing of stake length direction arrangement is 500~600mm, and gap is closed using high-strength epoxy resin between joint bar and joint bar hole.
Construction procedure includes:
(1) foundation soil is excavated to basement bottom board elevation of bottom position;
(2) casting concrete bottom plate
Ring seal slot is dug out in original outer surface, and watertight rubber ring is embedded in annular water stopping trough;Bind concrete floor Reinforcing bar, shearing resistance muscle, supporting module are simultaneously poured;
(3) in concrete raft plate following settings temporary steel support, temporary steel support uses I-steel, and spacing is arranged in I-steel For 2~2.5mm, setting cross bar is attached between adjacent I-steel, to guarantee the globality of I-shaped bracing members;Topmost cross bar It is 0.6~0.8mm from concrete raft plate distance from bottom, remaining cross bar distance is 1.8~2.2mm;
(4) original stake is reinforced, bearing column is formed;
Bearing column by original of part as basement, and original stake is reinforced;It is hollow pipe for original stake When stake, joint bar hole is set in hollow shell pill, joint bar is inserted into behind joint bar hole and is closed using high-strength epoxy resin, binding is held The principal rod of power column is simultaneously welded with joint bar, and supporting module, is then poured and is reinforced annular concrete in bearing column;
The pile concrete of concrete raft plate and basement bottom board in addition to bearing column is cut, and cuts off a reinforcing bar;
(5) the hollow shell pill hollow parts of the position concrete floor and concrete floor or less 500mm are protruded into using strong Concrete of the degree more than or equal to C30 is closed, and steel pallet is first transferred before concrete enclosing, steel pallet is as closed concrete Bracket, steel pallet is with a thickness of 15~18mm;
(6) the brushing polyurethane water-proof mortar on concrete floor.
Structure of the invention performance is good, securely and reliably.
